Description

洗衣機washing machine

發明領域
本發明是有關於一種清洗衣物等的洗滌物的洗衣機。FIELD OF THE INVENTION The present invention relates to a washing machine for washing laundry and the like.

發明背景
以往，已有將衣物等的洗滌物在旋轉槽內攪拌來進行清洗的直立型洗衣機、或是將洗滌物在旋轉槽內朝其旋轉方向提起後使其從上方落下來進行拍擊清洗的滾筒式洗衣機。不論何種洗衣機，都是構成為除了洗劑的化學力之外，還使機械力作用於洗滌物來進行清洗。BACKGROUND OF THE INVENTION Conventionally, there has been an upright washing machine in which laundry such as laundry is stirred in a rotary tub, or the laundry is lifted in a rotary tub in the direction of rotation, and then it is dropped from above to perform tap cleaning Drum type washing machine. No matter what kind of washing machine is used, in addition to the chemical force of the lotion, a mechanical force is applied to the laundry for washing.

上述洗衣機中，一種具有如下構成的一般洗衣機已在例如日本專利特開平10-201988號公報(以下標記為「專利文獻1」)中被提出，該構成是藉由以旋轉槽之高速旋轉所造成的離心力將水分從洗滌物分離的離心力脫水，來進行已清洗之洗滌物的脫水。Among the above-mentioned washing machines, a general washing machine having the following structure has been proposed, for example, in Japanese Patent Laid-Open No. 10-201988 (hereinafter referred to as "Patent Document 1"). This structure is caused by high-speed rotation with a rotating tank. The centrifugal force dehydrates the centrifugal force that separates the water from the laundry to dehydrate the washed laundry.

然而，使機械力作用於洗滌物來進行清洗的上述洗衣機並不適合以下所示之洗滌物的洗滌。又，清洗後的脫水中之離心力脫水並不適合以下所示之洗滌物。具體而言，是容易產生布料損傷的洗滌物、或是容易因洗滌物糾纏被拉扯而導致變形走樣的洗滌物等。甚至是觸感容易劣化(一般而言要手洗，例如毛衣、開襟毛衣等之毛線的編織物或毛織物、以極細纖維製作之細緻素材的圍巾等)的洗滌物等。However, the above-mentioned washing machine in which a mechanical force is applied to the laundry for washing is not suitable for washing the laundry shown below. In addition, centrifugal dehydration during dehydration after washing is not suitable for the laundry shown below. Specifically, it is a laundry which is prone to damage to cloth, or a laundry which is easily deformed due to entanglement and pulling of the laundry. Even the touch is easy to deteriorate (in general, hand-washing, such as knitted fabrics or woolen fabrics of sweaters, cardigan sweaters, scarves made of fine materials made of ultra-fine fibers, etc.).

一般而言，離心力脫水有脫水效率高的優點。但從另一面來看，卻容易產生旋轉槽之高速旋轉所造成的振動或噪音。因此，為了減低脫水動作時的振動、噪音，一種從洗滌物吸引水分來進行脫水的構成的洗衣機已在例如日本專利特開平7-222894號公報(以下標記為「專利文獻2」)中被提出。Generally speaking, centrifugal dehydration has the advantage of high dehydration efficiency. However, from the other side, it is easy to produce vibration or noise caused by the high-speed rotation of the rotating groove. Therefore, in order to reduce vibration and noise during a dehydration operation, a washing machine having a structure that absorbs moisture from laundry to perform dehydration has been proposed in, for example, Japanese Patent Laid-Open No. 7-222894 (hereinafter referred to as "Patent Document 2"). .

如圖8所示地，專利文獻2所記載的的滾筒式全自動洗衣機會從洗滌物52將水分與滾筒51內的空氣一併吸引。具體而言，上述洗衣機具有覆蓋滾筒51之外周壁並與滾筒51之通水孔53連通的吸引體54。然後，會藉由吸引泵55而通過吸引體54來吸引貼附於滾筒51之內周壁之洗滌物52所包含的水分。藉此，將洗滌物52所包含的水分脫水。As shown in FIG. 8, the drum type full-automatic washing machine described in Patent Document 2 sucks moisture from the laundry 52 together with the air in the drum 51. Specifically, the above-mentioned washing machine has an attracting body 54 that covers the outer peripheral wall of the drum 51 and communicates with the water passing hole 53 of the drum 51. Then, the water contained in the laundry 52 attached to the inner peripheral wall of the drum 51 is sucked by the suction body 54 by the suction pump 55. Thereby, the water contained in the laundry 52 is dehydrated.

亦即，藉由一起吸引空氣與洗淨水的吸引脫水方式，而變得可以進行抑制了洗滌物的布料損傷的脫水。然而，因空氣會流入洗淨水中，使得洗淨水所包含的洗劑成分會起泡。因此，必須構成為被吸引的水不會進入吸引空氣與洗淨水的吸引泵。所以，一般而言，具有上述構成的洗衣機會具備分離空氣與液體的氣液分離裝置。That is, by the suction dehydration method that sucks air and washing water together, it becomes possible to perform dehydration that suppresses damage to the cloth of the laundry. However, since air flows into the washing water, the lotion components contained in the washing water may foam. Therefore, the suction pump must be configured so that the suctioned water does not enter the suction pump for sucking air and washing water. Therefore, in general, a washing machine having the above-mentioned configuration is provided with a gas-liquid separation device that separates air and liquid.

更進一步地，一種具有防止在洗滌中所產生的洗劑泡沫朝風路等浸入的構成的洗衣機已在例如日本專利特開2008-253589號公報、日本專利特開2008-73126號公報(以下標記為「專利文獻3」、「專利文獻4」)等中被提出。Furthermore, a washing machine having a structure that prevents the detergent foam generated during washing from entering the wind path or the like has been disclosed in, for example, Japanese Patent Laid-Open No. 2008-253589 and Japanese Patent Laid-Open No. 2008-73126 (hereinafter referred to as "Patent Document 3", "Patent Document 4") and so on.

具體而言，如圖9所示地，專利文獻3所記載的滾筒式洗滌乾燥機具備在洗滌中阻塞風路57的閥體56。藉此，防止泡沫朝風路57的浸入。Specifically, as shown in FIG. 9, the drum-type washing and drying machine described in Patent Document 3 includes a valve body 56 that blocks the air passage 57 during washing. This prevents the foam from entering the air path 57.

又，如圖10所示地，專利文獻4所記載的滾筒式洗衣機具備：設置於水槽58內的泡沫偵測感測器59、及加熱送風部60。而且，是構成為在泡沫偵測感測器59偵測到水槽58內的起泡後，會藉由加熱送風部60，對已產生的泡沫吹附熱風來消泡。As shown in FIG. 10, the drum-type washing machine described in Patent Document 4 includes a foam detection sensor 59 provided in the water tank 58 and a heating air blowing unit 60. In addition, after the foam detection sensor 59 detects foaming in the water tank 58, it is configured to defoam by applying hot air to the generated foam by heating the air blowing unit 60.

然而，專利文獻2所記載的洗衣機的構成中，藉由吸引泵55所吸引之洗淨水與空氣，會在排水槽中被分離出水。此時，吸引體54內會因為吸引而被減壓，成為比大氣壓低的負壓。因此，從洗淨水產生的泡沫會因為負壓而膨脹增加。而且，膨脹後的泡沫會被吸引，而恐有泡沫浸入連接氣液分離裝置與吸引泵的風路、或是通過該風路而浸入吸引泵內之虞。However, in the configuration of the washing machine described in Patent Document 2, the washing water and air sucked by the suction pump 55 are separated in the drain tank. At this time, the inside of the suction body 54 is decompressed due to suction, and becomes a negative pressure lower than the atmospheric pressure. Therefore, the foam generated from the washing water may expand due to the negative pressure. Moreover, the expanded foam may be attracted, and there is a possibility that the foam may be immersed in the air path connecting the gas-liquid separation device and the suction pump or may be immersed in the suction pump through the air path.

發明概要
本發明提供一種在不適合使機械力作用來擰擠之被洗淨物的脫水動作時，會防止泡沫朝吸引部的浸入，而實現穩定之脫水性能的洗衣機。SUMMARY OF THE INVENTION The present invention provides a washing machine that can prevent the infiltration of foam toward the suction portion and achieve stable dehydration performance when it is unsuitable to use a mechanical force to spin the washed object.

本發明的洗衣機包含：洗淨槽，收容被洗淨物與洗淨水；按壓部，按壓洗淨槽內之被洗淨物；吸引部，從被洗淨物吸引洗淨水；及脫水路徑，連通連接洗淨槽與吸引部。更進一步地，洗衣機包含：外部氣體導入部，將外部氣體導入洗淨槽內；氣液分離部，設置於脫水路徑，並將已從被洗淨物吸引之洗淨水與空氣分離；及控制部，控制包含洗衣機的脫水動作之洗滌運轉。氣液分離部具有：儲水部，積存已吸引之洗淨水；水量偵測部，偵測積存於儲水部之洗淨水的量；及加壓部，使外部氣體流入儲水部內。而且，控制部在脫水動作中，會藉由按壓部按壓被洗淨物，並且藉由吸引部吸引洗淨水與空氣，並在藉由水量偵測部偵測到積存於儲水部之洗淨水成為規定量後，停止吸引部的驅動，並藉由加壓部使外部氣體流入儲水部內。The washing machine of the present invention comprises: a washing tank, which contains the objects to be washed and washing water; a pressing part, which presses the objects to be washed in the washing tank; a suction part, which sucks the washing water from the objects to be washed; and a dehydration path , Connect and connect the washing tank and the suction part. Furthermore, the washing machine includes: an external air introduction part to introduce external air into the washing tank; a gas-liquid separation part provided in the dehydration path, and separating washing water that has been attracted from the object to be cleaned from air; The unit controls a washing operation including a dehydration operation of the washing machine. The gas-liquid separation section includes a water storage section that stores the attracted washing water, a water amount detection section that detects the amount of the washing water stored in the water storage section, and a pressurizing section that allows external air to flow into the water storage section. In the dehydration operation, the control unit presses the object to be washed by the pressing unit, and sucks the washing water and air by the suction unit, and detects the washing stored in the water storage unit by the water amount detecting unit. After the purified water reaches a predetermined amount, the driving of the suction section is stopped, and the external air flows into the water storage section through the pressurizing section.

根據該構成，在脫水動作時，會防止泡沫朝吸引部的浸入，並從被洗淨物將洗淨水與被導入之外部氣體一併吸引。藉此，對於不適合透過由機械力的作用所造成之清洗或擰擠等洗滌動作來洗滌之被洗淨物，可以在不施加扭轉等機械力的情況下，良好地執行脫水。其結果，可以獲得能夠實現穩定之脫水性能的洗衣機。According to this configuration, during the dehydration operation, the foam is prevented from entering the suction portion, and the washing water is sucked together with the introduced external air from the object to be washed. With this, it is possible to perform dehydration well without applying mechanical force such as torsion to the washed object that is not suitable for washing by washing action such as washing or squeezing caused by the action of mechanical force. As a result, a washing machine capable of achieving stable dehydration performance can be obtained.

The second pressure reducing section 7b includes a second pressing section 8b, a second hose 9b, a second pressure pump 10b, a second on-off valve 11b, and the like.

此處，後續在將第1加壓減壓部7a及第2加壓減壓部7b總稱而進行說明時，僅單純標記為加壓減壓部7。又，在將第1按壓部8a及第2按壓部8b、第1軟管9a及第2軟管9b、第1加壓泵10a及第2加壓泵10b、第1開閉閥11a及第2開閉閥11b總稱而進行說明時，僅單純標記為按壓部8、軟管9、加壓泵10、及開閉閥11。亦即，針對個別顯示複數個的a、b的符號，只要不須特別區別，便會省略來進行標示。Herein, when the first pressurized and decompressed portion 7 a and the second pressurized and decompressed portion 7 b are collectively described below, they are simply labeled as the pressurized and decompressed portion 7. In addition, the first pressing portion 8a and the second pressing portion 8b, the first hose 9a and the second hose 9b, the first pressure pump 10a and the second pressure pump 10b, the first on-off valve 11a, and the second When the on-off valve 11 b is collectively described, only the pressing portion 8, the hose 9, the pressure pump 10, and the on-off valve 11 are simply labeled. That is, for a plurality of a and b symbols that are individually displayed, as long as there is no special difference, they will be omitted for labeling.

上述的加壓減壓部7是以：按壓部8、軟管9、加壓泵10、及開閉閥11等所構成。按壓部8是例如橡膠或合成樹脂等具有可撓性的袋狀，且形成為例如蛇腹狀。加壓泵10是通過軟管9而與按壓部8連通。加壓泵10在動作時，會通過軟管9而將氣體(例如，空氣等)、或液體(例如，水、水溶液或油等)等之流體供給至按壓部8之內部。開閉閥11會藉由開閉動作，將供給至按壓部8之流體朝外部排出、或蓄積於內部。The above-mentioned pressurizing and decompressing section 7 is constituted by a pressing section 8, a hose 9, a pressure pump 10, an on-off valve 11, and the like. The pressing portion 8 has a flexible bag shape such as rubber or synthetic resin, and is formed into a bellows shape, for example. The pressure pump 10 communicates with the pressing portion 8 through a hose 9. When the pressure pump 10 operates, a fluid such as gas (for example, air or the like) or liquid (for example, water, aqueous solution, or oil) is supplied to the inside of the pressing section 8 through the hose 9. The on-off valve 11 discharges or accumulates the fluid supplied to the pressing portion 8 to the outside through the opening and closing operation.

第1加壓減壓部7a與第2加壓減壓部7b是在蓋體5的內側，於例如前後方向上排列配設。加壓減壓部7的按壓部8是安裝於蓋體5之蓋部5b的洗淨槽4側(下方側)，並藉由膨脹收縮而構成為伸縮自如。亦即，按壓部8是構成為會相對於收容在洗淨槽4之底部4a之被洗淨物2，在例如上下方向上進退自如。The first pressure-reducing and pressure-reducing portion 7 a and the second pressure-reducing and pressure-reducing portion 7 b are arranged inside the cover body 5 in the front-rear direction, for example. The pressing portion 8 of the pressurizing and decompressing portion 7 is attached to the washing tank 4 side (lower side) of the cover portion 5 b of the cover body 5 and is configured to expand and contract freely by expansion and contraction. That is, the pressing portion 8 is configured to move forward and backward in the vertical direction with respect to the object 2 to be cleaned accommodated in the bottom portion 4 a of the cleaning tank 4.

具體而言，按壓部8包含：按壓被洗淨物2的按壓面8c、及蛇腹狀的伸縮部8d。按壓部8在被洗淨物2的洗滌運轉時，伸縮部8d會伸長至按壓面8c到達洗淨槽4之底部4a的程度為止。Specifically, the pressing portion 8 includes a pressing surface 8c that presses the object 2 to be washed, and a bellows-like telescopic portion 8d. When the pressing portion 8 is in the washing operation of the object 2 to be washed, the telescopic portion 8 d is extended until the pressing surface 8 c reaches the bottom portion 4 a of the washing tank 4.

加壓減壓部7更包含：當按壓部8之內部成為規定的壓力時，會開放以朝外部排出的定壓開放閥(未圖示)。定壓開放閥會防止按壓部8被加壓超過規定的壓力。另外，實施形態1中，是以供給至按壓部8之內部的流體為空氣的情況為例子進行說明。The pressure reducing section 7 further includes a constant pressure release valve (not shown) that is opened to be discharged to the outside when the inside of the pressing section 8 reaches a predetermined pressure. The constant pressure release valve prevents the pressing portion 8 from being pressurized beyond a predetermined pressure. In the first embodiment, a case where the fluid supplied to the inside of the pressing portion 8 is air will be described as an example.

蓋部5b包含：環狀地設置於按壓部8的外側且變形自如之中空的墊件12。墊件12在蓋部5b與蓋體5一併被關閉時，會與沿著洗淨槽4的開口部3之周緣部形成為凹狀的密封部13密接。藉此，洗淨槽4之內部會成為水密且氣密的空間。因此，在洗滌運轉時，可防止水或空氣從洗淨槽4的開口部3朝外部洩漏。The cover portion 5 b includes a hollow cushion 12 that is provided annularly on the outside of the pressing portion 8 and is freely deformable. When the cover member 5 b is closed together with the cover body 5, the cushion member 12 is in close contact with the sealing portion 13 formed in a concave shape along the peripheral edge portion of the opening portion 3 of the washing tank 4. Thereby, the inside of the washing tank 4 becomes a watertight and airtight space. Therefore, during the washing operation, water or air can be prevented from leaking from the opening 3 of the washing tank 4 to the outside.

在蓋體5會配設將洗淨水供給至洗淨槽4的供水路徑16。在供水路徑16會配設供水閥14，並透過洗劑盒15來與洗淨槽4之內部連通。藉由供水閥14的開閉動作，來進行朝洗淨槽4之內部的自來水(洗淨水)的供水與停止。The lid body 5 is provided with a water supply path 16 for supplying washing water to the washing tank 4. A water supply valve 14 is provided in the water supply path 16 and communicates with the inside of the washing tank 4 through the detergent box 15. The opening and closing operation of the water supply valve 14 supplies and stops the supply of tap water (washing water) to the inside of the washing tank 4.

水位偵測部17是連通洗淨槽4之內部而設置。水位偵測部17會偵測積存於洗淨槽4內之洗淨水的水位。The water level detection unit 17 is provided in communication with the inside of the washing tank 4. The water level detecting section 17 detects the water level of the washing water stored in the washing tank 4.

水位偵測部17包含：在上方具有開口部的水位偵測槽18、浮標(float)19、及水位開關20等。浮標19會因應水位偵測槽18內的水位之變動而上下浮動。水位開關20會在浮標19藉由洗淨水的供給而上升至規定的位置時，偵測到該情況。The water level detection unit 17 includes a water level detection tank 18 having an opening above, a float 19, a water level switch 20, and the like. The buoy 19 will float up and down in response to changes in the water level in the water level detection tank 18. The water level switch 20 detects this when the buoy 19 is raised to a predetermined position by the supply of washing water.

洗淨槽4包含：形成於底部4a，且會將清洗步驟等所使用之洗淨水排出的排水孔21。排水孔21會與配設有排水閥22的排水路徑23連通。藉由排水閥22的開閉，會執行洗淨槽4之內部的洗淨水的排水與停止。The washing tank 4 includes a drainage hole 21 formed in the bottom 4a and discharging the washing water used in the washing step and the like. The drain hole 21 communicates with a drain path 23 provided with a drain valve 22. The opening and closing of the drain valve 22 drains and stops the washing water inside the washing tank 4.

又，水槽部6包含溢水路徑24。溢水路徑24是構成在洗淨槽4之內部的洗淨水的水位成為規定以上時，將洗淨水從洗淨槽4排水至外部的路徑。溢水路徑24具有在洗淨槽4之上部開口的溢水孔24a，並在排水閥22之下游側與排水路徑23連接。The water tank portion 6 includes an overflow path 24. The overflow path 24 is a path for draining the washing water from the washing tank 4 to the outside when the level of the washing water included in the washing tank 4 becomes a predetermined level or more. The overflow path 24 has an overflow hole 24 a opened on the upper part of the washing tank 4, and is connected to the drain path 23 on the downstream side of the drain valve 22.

在溢水路徑24會配設止回閥(未圖示)。止回閥在溢水路徑24中，是以在出自洗淨槽4之排出方向上開放，且在朝洗淨槽4之流入方向上封閉(閉塞)的方式來動作。亦即，止回閥在清洗步驟及沖洗步驟中，會使從溢水孔24a流出之洗淨水通過並朝外部排出。又，止回閥在沖洗步驟及脫水步驟的脫水動作時，在以後述之吸引泵27吸引洗淨槽4之內部的空氣的情況下，會防止外部氣體通過溢水路徑24朝洗淨槽4之內部流入。A check valve (not shown) is provided in the overflow path 24. The check valve operates in the overflow path 24 so as to be opened in the discharge direction from the washing tank 4 and closed (closed) in the inflow direction of the washing tank 4. That is, in the cleaning step and the flushing step, the check valve allows the washing water flowing out of the overflow hole 24a to pass through and is discharged to the outside. In the dehydration operation of the flushing step and the dewatering step, the check valve prevents the outside air from passing through the overflow path 24 toward the washing tank 4 when the suction pump 27 sucks the air inside the washing tank 4 described later. Internal inflow.

更進一步地，洗淨槽4包含：設置於底部4a之大致中央部(包含中央部)的吸引口25。當被洗淨物2被放置於洗淨槽4之內部時，吸引口25會藉由被洗淨物2而被覆蓋。吸引口25是連通脫水路徑26而設置。Furthermore, the washing tank 4 includes a suction port 25 provided at a substantially central portion (including the central portion) of the bottom portion 4a. When the object to be cleaned 2 is placed inside the cleaning tank 4, the suction port 25 is covered by the object to be cleaned 2. The suction port 25 is provided in communication with the dehydration path 26.

吸引部即吸引泵27是透過後述之氣液分離部30及吸引路徑32，來連通脫水路徑26而配設。吸引泵27會從被洗淨物2吸引洗淨水等。The suction pump 27, which is a suction unit, is arranged to communicate with the dewatering path 26 through a gas-liquid separation unit 30 and a suction path 32 described later. The suction pump 27 sucks washing water and the like from the object 2 to be washed.

當藉由吸引泵27從被洗淨物2吸引洗淨水時，洗淨槽4之內部的空氣也會被吸引。因此，會配設將外部氣體從洗淨槽4之外部導入內部的外部氣體導入部28。另外，外部氣體導入部28只要是在比積存於洗淨槽4之內部的洗淨水的水位更上方側形成開口的構成，配設位置便可為任意。例如在圖1、圖2、及圖4中，外部氣體導入部28是配置於與洗淨槽4之內部連通之水位偵測部17的上方側。又，在圖3A、及圖3B中，外部氣體導入部28是配設於洗淨槽4的上方側。When the washing water is sucked from the object to be washed 2 by the suction pump 27, the air inside the washing tank 4 is also sucked. Therefore, an external air introduction part 28 for introducing external air into the interior from the outside of the washing tank 4 is provided. In addition, the arrangement position of the outside air introduction part 28 may be arbitrary as long as it is a structure which forms an opening above the water level of the wash water accumulated in the inside of the washing tank 4, and is provided. For example, in FIG. 1, FIG. 2, and FIG. 4, the outside air introduction section 28 is disposed above the water level detection section 17 that communicates with the inside of the washing tank 4. In FIG. 3A and FIG. 3B, the outside air introduction part 28 is disposed on the upper side of the washing tank 4.

外部氣體導入部28具備風量調整閥29。風量調整閥29會調節被導入洗淨槽4內之外部氣體的風量。風量調整閥29是例如像針閥(needle valve)一樣地在流路具有狹小的風路面積部。藉由風路面積部的調整，而構成為可以調整藉由吸引泵27而被吸引至洗淨槽4內之外部氣體的風量。另外，被導入洗淨槽4之外部氣體亦可從洗衣機1之外部直接導入。又，亦可作成為經由洗衣機1之內部空間，來將外部氣體導入洗淨槽4的構成。The outside air introduction unit 28 includes an air volume adjustment valve 29. The air volume adjustment valve 29 adjusts the air volume of the external air introduced into the washing tank 4. The air volume adjustment valve 29 has a narrow air passage area portion in a flow path like a needle valve, for example. The air passage area is adjusted to adjust the air volume of the external air that is sucked into the washing tank 4 by the suction pump 27. The outside air introduced into the washing tank 4 may be directly introduced from the outside of the washing machine 1. Moreover, it can also be set as the structure which introduce | transduces external air into the washing tank 4 through the internal space of the washing machine 1.

在脫水路徑26會配設氣液分離部30。氣液分離部30會將洗淨槽4內的空氣、與已從被洗淨物2吸引之洗淨水分離，並將已吸引之洗淨水儲水。具體而言，氣液分離部30包含：以耐壓容器所構成的儲水部30a。儲水部30a包含：形成於上方且與脫水路徑26連通的二次側通風口31、及通過吸引路徑32且與吸引泵27連通的一次側通風口33。在一次側通風口33與二次側通風口31之間會設置障壁34。障壁34是從氣液分離部30的頂面朝下方突出而形成。障壁34會防止從二次側通風口31被吸引至氣液分離部30內之洗淨水朝一次側通風口33浸入。A gas-liquid separation unit 30 is provided in the dehydration path 26. The gas-liquid separation unit 30 separates the air in the washing tank 4 from the washing water that has been sucked from the object to be washed 2 and stores the sucked washing water. Specifically, the gas-liquid separation unit 30 includes a water storage unit 30a constituted by a pressure-resistant container. The water storage unit 30 a includes a secondary air vent 31 formed above and communicating with the dewatering path 26, and a primary air vent 33 communicating with the suction pump 27 through the suction path 32. A barrier 34 is provided between the primary air vent 33 and the secondary air vent 31. The barrier 34 is formed to protrude downward from the top surface of the gas-liquid separation unit 30. The barrier 34 prevents the washing water drawn into the gas-liquid separation unit 30 from the secondary air vent 31 from entering the primary air vent 33.

氣液分離部30具有設置於底部的脫水排水口35。脫水排水口35會連通具有開閉自如之脫水排水閥36的脫水排水路徑37。The gas-liquid separation unit 30 includes a dehydration and drainage port 35 provided at the bottom. The dewatering drainage port 35 communicates with a dewatering drainage path 37 having a dewatering drainage valve 36 that can be opened and closed freely.

又，氣液分離部30具備設置於內壁之規定高度位置的水量偵測部38。具體而言，設置水量偵測部38的高度位置宜相對於儲水部30a可儲水之最大水位在1/2到4/5的範圍內為佳。The gas-liquid separation unit 30 includes a water amount detection unit 38 provided at a predetermined height position on the inner wall. Specifically, it is preferable that the height position of the water detection unit 38 is set within a range of 1/2 to 4/5 with respect to the maximum water level that the water storage unit 30a can store water.

水量偵測部38是以例如1對電極等所構成。水量偵測部38會偵測到氣液分離部30的儲水部30a所儲水之洗淨水已到達規定量。更進一步地，水量偵測部38在洗淨水包含泡沫時，會偵測到泡沫之上部已到達規定高度位置。亦即，在水量偵測部38偵測到洗淨水(水及/或泡沫)後，後述之控制部40會開啟脫水排水閥36。藉此，洗淨水會通過脫水排水路徑37而朝機外排水。The water amount detection unit 38 is configured by, for example, a pair of electrodes. The water detection unit 38 detects that the washing water stored in the water storage unit 30a of the gas-liquid separation unit 30 has reached a predetermined amount. Furthermore, when the washing water contains foam, the water amount detecting unit 38 detects that the upper portion of the foam has reached a predetermined height position. That is, after the washing water (water and / or foam) is detected by the water amount detecting unit 38, the control unit 40 described later will open the dehydration and drainage valve 36. As a result, the washing water is discharged outside the machine through the dewatering drainage path 37.

此處，當洗淨水包含泡沫時，若泡沫附著且殘留於障壁34，便會成為臭味的主要原因。為了防止該泡沫殘留，在偵測洗淨水時，水量偵測部38會配設於：在障壁34的下端與洗淨水面之間有一定空間存在的位置。亦即，水量偵測部38會偵測已考慮到洗淨水所包含的泡沫量之規定量。Here, when the washing water contains foam, if the foam adheres and remains on the barrier ribs 34, it becomes a cause of odor. In order to prevent the foam from remaining, when detecting the washing water, the water amount detecting unit 38 is disposed at a position where a certain space exists between the lower end of the barrier 34 and the washing water surface. That is, the water amount detecting unit 38 detects a predetermined amount that takes into account the amount of foam contained in the washing water.

加壓部即開放閥39是配設於連通連接氣液分離部30與吸引泵27的吸引路徑32之分岐的路徑。藉由開放閥39的開閉，會進行氣液分離部30內與大氣(外部氣體)的連通或阻斷。The open valve 39 which is a pressurizing section is a path provided in a branched manner between the suction path 32 that connects the gas-liquid separation section 30 and the suction pump 27. By opening and closing the open valve 39, communication or blocking of the atmosphere (outside air) in the gas-liquid separation unit 30 is performed.

控制部40是配設於蓋體5內部之前方的側面部。控制部40是在上表面配設操作顯示部41。控制部40會依據被輸入的資訊，控制各種構成要素，來執行洗滌運轉。The control unit 40 is a side surface portion disposed in front of the inside of the cover 5. The control section 40 is provided with an operation display section 41 on the upper surface. The control unit 40 executes a washing operation by controlling various components based on the inputted information.

具體而言，控制部40會被輸入以水位偵測部17所偵測到的洗淨槽4內之洗淨水的水位、及以水量偵測部38所偵測到的儲水部30a內之洗淨水的量等資訊。Specifically, the control section 40 is input with the water level of the washing water in the washing tank 4 detected by the water level detection section 17 and the water storage section 30a detected by the water amount detection section 38. The amount of washing water and other information.

而且，控制部40會依據該等輸入資訊，控制加壓泵10、開閉閥11、供水閥14、排水閥22、吸引泵27、風量調整閥29、脫水排水閥36、及開放閥39等的動作。藉此，控制部40會依次控制清洗步驟、沖洗步驟、及脫水步驟等各步驟，來執行洗滌運轉。另外，控制部40是以例如微電腦等所構成。In addition, the control unit 40 controls the pressure pump 10, the on-off valve 11, the water supply valve 14, the drain valve 22, the suction pump 27, the air volume adjustment valve 29, the dewatering drain valve 36, and the open valve 39 based on the input information. action. Thereby, the control part 40 sequentially controls each step, such as a washing process, a washing process, and a spin-drying process, and performs a washing operation. The control unit 40 is configured by, for example, a microcomputer.

如以上地，即構成實施形態1的洗衣機1。As described above, the washing machine 1 of the first embodiment is configured.

以下，針對上述構成之洗衣機1的動作及作用進行說明。The operation and effect of the washing machine 1 configured as described above will be described below.

首先，使用者會透過設置於蓋體5之上表面前部的操作顯示部41，來輸入洗滌行程的選擇或各步驟的動作時間等。藉此，控制部40會依據已輸入的設定內容，執行例如圖5所示之從清洗步驟到脫水步驟為止的各步驟之一系列動作來作為洗滌行程。此時，使用者可以任意地設定例如僅執行清洗步驟等的內容。另外，上述設定作業亦可在將後述之被洗淨物2放置於洗淨槽4內之底部4a後再進行。First, the user inputs the selection of a washing course, the operation time of each step, and the like through the operation display portion 41 provided on the front portion of the upper surface of the cover 5. As a result, the control unit 40 executes a series of operations such as each step from the washing step to the dehydration step shown in FIG. 5 as a washing cycle according to the input setting content. At this time, the user can arbitrarily set, for example, the content such that only the washing step is performed. In addition, the above-mentioned setting operation may be performed after the to-be-cleaned object 2 described later is placed on the bottom portion 4 a in the washing tank 4.

接著，使用者會操作蓋體5之握把5a，來將鎖定洗淨槽4與蓋體5的鎖定裝置解鎖。然後，使用者會開啟蓋體5，並將被洗淨物2的形狀整理後，以至少會覆蓋吸引口25的方式放置於洗淨槽4之底部4a。此時，視被洗淨物2的大小，亦可摺疊放置。Next, the user operates the handle 5a of the cover 5 to unlock the locking device for locking the washing tank 4 and the cover 5. Then, the user opens the cover 5 and arranges the shape of the object 2 to be cleaned, and then places it on the bottom 4a of the cleaning tank 4 so as to cover at least the suction opening 25. At this time, depending on the size of the object 2 to be washed, it may be folded.

接著，當被洗淨物2的放置結束後，使用者會以蓋體5來關閉洗淨槽4的開口部3，並藉由鎖定裝置來鎖定洗淨槽4與蓋體5。After the placement of the object to be cleaned 2 is completed, the user closes the opening 3 of the washing tank 4 with the cover 5 and locks the washing tank 4 and the cover 5 with a locking device.

然後，控制部40會因應以操作顯示部41所設定的例如圖5所示之洗滌行程，來開始洗滌運轉。Then, the control unit 40 starts the washing operation in accordance with the washing schedule set in the operation display unit 41, for example, as shown in FIG.

以下，以圖5所示之洗滌行程為例子，針對洗衣機的動作及作用進行說明。The operation and function of the washing machine will be described below using the washing cycle shown in FIG. 5 as an example.

一開始，作為洗滌行程，針對僅設定了清洗步驟之情況下的洗衣機1的動作及作用，具體地進行說明。First, as the washing cycle, the operation and effect of the washing machine 1 when only the washing step is set will be specifically described.

在清洗步驟中，控制部40會執行例如供水動作、及清洗動作。In the cleaning step, the control unit 40 performs, for example, a water supply operation and a cleaning operation.

首先，在清洗步驟中，控制部40會進行供水動作。亦即，控制部40會開放供水閥14。藉由供水閥14的開放，自來水與洗劑會作為洗淨水，經由洗劑盒15而從供水路徑16供給至洗淨槽4之內部。被供給至洗淨槽4之洗淨水會慢慢地滲透至被洗淨物2之內部。藉此，會成為在被洗淨物2的纖維之間包含有洗淨水的狀態。First, in the washing step, the control unit 40 performs a water supply operation. That is, the control unit 40 opens the water supply valve 14. When the water supply valve 14 is opened, tap water and lotion are used as washing water and are supplied from the water supply path 16 to the inside of the washing tank 4 through the lotion box 15. The washing water supplied to the washing tank 4 slowly penetrates into the inside of the object 2 to be washed. As a result, a state is obtained in which washing water is contained between the fibers of the object 2 to be washed.

接著，控制部40會以水位偵測部17的水位開關20來監視洗淨水是否已供給至洗淨槽4之內部的規定水位。然後，在以水位開關20偵測到洗淨水已供給至規定水位後，控制部40會關閉供水閥14。Next, the control unit 40 monitors whether or not the washing water has been supplied to a predetermined water level inside the washing tank 4 with the water level switch 20 of the water level detecting unit 17. After detecting that the washing water has been supplied to a predetermined water level with the water level switch 20, the control unit 40 closes the water supply valve 14.

供水動作結束後，在清洗步驟中，控制部40會執行清洗動作。亦即，控制部40首先會關閉第1加壓減壓部7a的第1開閉閥11a。然後，控制部40會將第1加壓泵10a驅動規定時間、或直到第1按壓部8a到達規定壓為止。藉此，空氣會被供給至第1按壓部8a之內部，第1按壓部8a便會膨脹。After the water supply operation is completed, the control unit 40 executes the cleaning operation in the cleaning step. That is, the control unit 40 first closes the first on-off valve 11a of the first pressurizing and decompressing unit 7a. Then, the control unit 40 drives the first pressure pump 10a for a predetermined time or until the first pressing part 8a reaches a predetermined pressure. As a result, air is supplied to the inside of the first pressing portion 8a, and the first pressing portion 8a is expanded.

具體而言，如圖3A所示地，藉由朝第1按壓部8a之內部的空氣供給，第1按壓部8a的伸縮部8d會向下方伸長，第1按壓部8a便會朝向被洗淨物2延伸。藉此，放置於第1按壓部8a之下方的被洗淨物2會被第1按壓部8a的按壓面8c按壓，且被按壓之被洗淨物2的部分會被壓縮。因此，被洗淨物2的厚度會變薄。此時，控制部40會開放第2加壓減壓部7b的第2開閉閥11b，以將第2按壓部8b作成為可收縮的狀態。Specifically, as shown in FIG. 3A, by supplying air to the inside of the first pressing portion 8a, the telescopic portion 8d of the first pressing portion 8a is extended downward, and the first pressing portion 8a is washed toward the target.物 2Extended. As a result, the object to be cleaned 2 placed below the first pressing part 8a is pressed by the pressing surface 8c of the first pressing part 8a, and the part of the object 2 to be washed that is pressed is compressed. Therefore, the thickness of the object to be washed 2 becomes thin. At this time, the control unit 40 opens the second on-off valve 11b of the second pressurizing and decompressing unit 7b, so that the second pressing unit 8b can be contracted.

亦即，藉由第1按壓部8a的膨脹，被洗淨物2會被壓縮，且體積會變化。藉此，被洗淨物2之內部所包含之洗淨水會從被洗淨物2擠出。此時，在被洗淨物2之內部會產生水流。其結果，附著於被洗淨物2的髒污會藉由水流而從纖維等分離而被除去。That is, by the expansion of the first pressing portion 8a, the object to be washed 2 is compressed, and the volume thereof changes. Thereby, the washing water contained in the inside of the to-be-washed object 2 is squeezed out from the to-be-washed object 2. At this time, a water flow is generated inside the object to be cleaned 2. As a result, the dirt adhering to the object to be cleaned 2 is separated from the fibers and the like by the water flow and removed.

又，被洗淨物2所包含之洗淨水會在被洗淨物2之內部，從第1按壓部8a之下方朝第2按壓部8b之下方，亦即，朝圖3A之以箭頭A所示的方向移動。此時，會藉由移動之洗淨水，一邊使第2按壓部8b之下方的被洗淨物2例如向上方膨脹，一邊將第2按壓部8b的按壓面8c朝上方上推。藉此，第2按壓部8b之內部的空氣會從開放的第2開閉閥11b被排出。其結果，第2按壓部8b便會收縮。In addition, the washing water included in the object to be washed 2 will be inside the object to be washed 2 from below the first pressing portion 8a to below the second pressing portion 8b, that is, toward the arrow A in FIG. 3A Move in the direction shown. At this time, the moving object is used to push the pressing surface 8c of the second pressing portion 8b upward while expanding the object to be washed 2 below the second pressing portion 8b. Thereby, the air inside the second pressing portion 8b is discharged from the opened second on-off valve 11b. As a result, the second pressing portion 8b contracts.

接著，控制部40會關閉第2加壓減壓部7b的第2開閉閥11b。然後，控制部40會將第2加壓泵10b驅動規定時間、或直到第2按壓部8b到達規定壓為止。藉此，空氣會被供給至第2按壓部8b之內部，第2按壓部8b便會膨脹。Next, the control unit 40 closes the second on-off valve 11b of the second pressurizing and decompressing unit 7b. Then, the control unit 40 drives the second pressure pump 10b for a predetermined time or until the second pressing unit 8b reaches a predetermined pressure. As a result, air is supplied to the inside of the second pressing portion 8b, and the second pressing portion 8b is expanded.

具體而言，如圖3B所示地，藉由朝第2按壓部8b之內部的空氣供給，第2按壓部8b的伸縮部8d會向下方伸長，第2按壓部8b便會朝向被洗淨物2延伸。而且，放置於第2按壓部8b之下方的被洗淨物2會被第2按壓部8b的按壓面8c按壓，且被按壓之被洗淨物2的部分會被壓縮。因此，被洗淨物2的厚度會變薄。此時，控制部40會開放第1加壓減壓部7a的第1開閉閥11a，以將第1按壓部8a作成為可收縮的狀態。Specifically, as shown in FIG. 3B, by supplying air to the inside of the second pressing portion 8b, the telescopic portion 8d of the second pressing portion 8b is extended downward, and the second pressing portion 8b is washed toward the target.物 2Extended. Further, the object to be cleaned 2 placed below the second pressing part 8b is pressed by the pressing surface 8c of the second pressing part 8b, and the part of the object 2 to be washed that is pressed is compressed. Therefore, the thickness of the object to be washed 2 becomes thin. At this time, the control unit 40 opens the first on-off valve 11a of the first pressurizing and decompressing unit 7a, so that the first pressing unit 8a can be contracted.

亦即，藉由第2按壓部8b的膨脹，被洗淨物2會被壓縮，且體積會變化。藉此，被洗淨物2之內部所包含之洗淨水會從被洗淨物2擠出。此時，在被洗淨物2之內部會產生水流。其結果，附著於被洗淨物2的髒污會藉由水流而從纖維等分離而被除去。That is, by the expansion of the second pressing portion 8b, the object 2 to be washed is compressed, and the volume thereof is changed. Thereby, the washing water contained in the inside of the to-be-washed object 2 is squeezed out from the to-be-washed object 2. At this time, a water flow is generated inside the object to be cleaned 2. As a result, the dirt adhering to the object to be cleaned 2 is separated from the fibers and the like by the water flow and removed.

又，被洗淨物2所包含之洗淨水會在被洗淨物2之內部，從第2按壓部8b之下方朝第1按壓部8a之下方，亦即，朝圖3B之以箭頭B所示的方向移動。此時，會藉由移動之洗淨水，一邊使第1按壓部8a之下方的被洗淨物2例如向上方膨脹，一邊將第1按壓部8a的按壓面8c朝上方上推。藉此，第1按壓部8a之內部的空氣會從開放的第1開閉閥11a被排出。其結果，第1按壓部8a便會收縮。In addition, the washing water included in the object to be washed 2 will be inside the object to be washed 2 from below the second pressing portion 8b to below the first pressing portion 8a, that is, toward arrow B in FIG. 3B Move in the direction shown. At this time, the moving object is used to push the pressing surface 8c of the first pressing portion 8a upward while expanding the object to be washed 2 below the first pressing portion 8a. Thereby, the air inside the first pressing portion 8a is discharged from the opened first on-off valve 11a. As a result, the first pressing portion 8a is contracted.

亦即，在清洗動作中，會以不同的時間點交互地使第1按壓部8a與第2按壓部8b反覆膨脹與收縮規定時間。藉此，對被洗淨物2會發揮搓洗效果。因此，攪拌或拍擊清洗等所造成之機械力不會對被洗淨物2作用。亦即，會使被洗淨物2之內部產生在多方向上移動的水流。藉此，便可在不使機械力作用的情況下，將被洗淨物2的髒污除去。此處，上述的膨脹與收縮之不同的時間點具體而言，是例如由第1按壓部8a的膨脹所進行的加壓1秒、由第2按壓部8b的收縮所進行的減壓1秒。又，規定時間是例如10分鐘左右。另外，膨脹與收縮之不同的時間點及規定時間當然不限於上述值，只要因應被洗淨物2的狀態來任意設定即可。That is, during the cleaning operation, the first pressing portion 8a and the second pressing portion 8b are repeatedly expanded and contracted repeatedly at different time points for a predetermined time. As a result, a scrubbing effect is exerted on the object 2 to be washed. Therefore, the mechanical force caused by stirring, tapping, washing, etc. does not act on the object 2 to be cleaned. That is, a water flow that moves in multiple directions is generated inside the object to be cleaned 2. Thereby, the stain | pollution | contamination of the to-be-cleaned object 2 can be removed without applying a mechanical force. Here, specifically, the time difference between the expansion and contraction described above is, for example, pressing for 1 second by the expansion of the first pressing portion 8a, and decompressing for 1 second by the contraction of the second pressing portion 8b. . The predetermined time is, for example, about 10 minutes. In addition, it is needless to say that the time point and the predetermined time at which the expansion and contraction differ are not limited to the above values, and may be arbitrarily set in accordance with the state of the object 2 to be washed.

如以上地，僅執行清洗步驟來作為洗滌行程。As described above, only the washing step is performed as the washing course.

以下，針對設定了一貫地執行從清洗步驟到脫水步驟為止的洗滌行程的情況進行說明。Hereinafter, a case where a washing cycle from the washing step to the dehydration step is set consistently will be described.

在此情況下，控制部40首先會執行上述的清洗步驟。In this case, the control unit 40 first performs the above-mentioned cleaning step.

然後，在清洗步驟之後，控制部40會接著依序執行沖洗步驟、及脫水步驟。After the washing step, the control unit 40 then sequentially performs the washing step and the dehydration step.

在沖洗步驟中，控制部40是例如執行脫水動作及蓄水漂洗動作。以下，將沖洗步驟中的脫水動作標記為中間脫水動作。In the rinsing step, the control unit 40 performs, for example, a dehydration operation and a water storage rinsing operation. Hereinafter, the dehydration operation in the washing step is referred to as an intermediate dehydration operation.

亦即，控制部40在中間脫水動作中，首先會開放排水閥22來進行排水。藉此，洗淨槽4內之洗淨水會從排水孔21通過排水路徑23而朝外部排水。That is, in the intermediate dehydration operation, the control unit 40 first opens the drain valve 22 to drain water. As a result, the washing water in the washing tank 4 is discharged from the drainage hole 21 through the drainage path 23 to the outside.

排水結束後，控制部40會在中間脫水動作中進行壓縮。亦即，控制部40會在開放排水閥22的狀態下，關閉第1開閉閥11a及第2開閉閥11b，並驅動第1加壓泵10a及第2加壓泵10b。藉此，第1按壓部8a及第2按壓部8b會膨脹，被洗淨物2便會被按壓而被壓縮。其結果，被洗淨物2所包含之洗淨水的一部分會從被洗淨物2被擠出，並從排水孔21強制地被排出。After the drainage is completed, the control unit 40 compresses during the intermediate dehydration operation. That is, the control unit 40 closes the first on-off valve 11 a and the second on-off valve 11 b in a state where the drain valve 22 is opened, and drives the first pressure pump 10 a and the second pressure pump 10 b. Thereby, the 1st pressing part 8a and the 2nd pressing part 8b expand, and the to-be-cleaned material 2 is pressed and compressed. As a result, a part of the washing water included in the object to be washed 2 is squeezed out from the object to be washed 2 and is forcibly discharged from the drainage hole 21.

壓縮結束後，控制部40會在中間脫水動作中進行吸引。亦即，控制部40會在按壓被洗淨物2的狀態下，關閉排水閥22，並驅動吸引泵27。藉此，外部氣體會透過風量調整閥29而從外部氣體導入部28被導入洗淨槽4之內部。藉由被導入之外部氣體，洗淨槽4內之洗淨水與空氣會從吸引口25被吸引，並通過脫水路徑26而被搬運至氣液分離部30。更進一步地，被吸引的空氣會藉由吸引泵27而朝外部排出。另一方面，洗淨水會積存於氣液分離部30的儲水部30a，藉此來進行被洗淨物2的脫水。After the compression is completed, the control unit 40 sucks during the intermediate dehydration operation. That is, the control unit 40 closes the drain valve 22 and drives the suction pump 27 in a state where the object to be washed 2 is pressed. Thereby, the outside air passes through the air volume adjustment valve 29 and is introduced into the washing tank 4 from the outside air introduction part 28. With the introduced external air, the washing water and air in the washing tank 4 are sucked from the suction port 25 and are conveyed to the gas-liquid separation unit 30 through the dehydration path 26. Furthermore, the sucked air is discharged to the outside by the suction pump 27. On the other hand, the washing water is accumulated in the water storage unit 30 a of the gas-liquid separation unit 30, and thereby the object to be washed 2 is dehydrated.

在沖洗步驟中，控制部40在脫水動作之後，會接著執行蓄水漂洗動作。In the rinsing step, after the dehydration operation, the control unit 40 then performs a water storage rinsing operation.

在蓄水漂洗動作中，控制部40首先會進行供水。控制部40會開放供水閥14，並將規定量之洗淨水供給至洗淨槽4之內部。此時，洗劑盒15內的洗劑在上述的清洗步驟中會全部使完。因此，蓄水漂洗動作時之洗淨水是自來水。In the water storage rinsing operation, the control unit 40 first supplies water. The control unit 40 opens the water supply valve 14 and supplies a predetermined amount of washing water to the inside of the washing tank 4. At this time, the lotion in the lotion box 15 is completely used up in the above-mentioned washing step. Therefore, the washing water during the water rinsing operation is tap water.

然後，與上述的清洗動作同樣地，控制部40會驅動第1加壓泵10a及第2加壓泵10b，交互且反覆地執行第1按壓部8a及第2按壓部8b的膨脹與收縮。藉此，被洗淨物2之內部的洗淨水的洗劑濃度會被稀釋。Then, similar to the cleaning operation described above, the control unit 40 drives the first pressure pump 10a and the second pressure pump 10b, and executes the expansion and contraction of the first pressing portion 8a and the second pressing portion 8b alternately and repeatedly. As a result, the detergent concentration of the washing water inside the object to be washed 2 is diluted.

以上，沖洗步驟便結束。This concludes the rinsing step.

然後，控制部40會反覆執行上述沖洗步驟複數次(例如2次)。具體而言，會執行圖5所示之沖洗步驟1與沖洗步驟2。此時，在沖洗步驟1與沖洗步驟2之間，也會執行與上述同樣的中間脫水動作。Then, the control unit 40 repeatedly executes the above-mentioned rinsing step a plurality of times (for example, twice). Specifically, the rinsing step 1 and the rinsing step 2 shown in FIG. 5 are performed. At this time, between the rinsing step 1 and the rinsing step 2, the same intermediate dehydration operation as described above is also performed.

接著，控制部40在執行沖洗步驟之後，會執行圖5所示之脫水步驟。在脫水步驟中，會執行脫水動作。以下，將脫水步驟中的脫水動作標記為最終脫水動作。Next, the control unit 40 executes the dehydration step shown in FIG. 5 after performing the rinsing step. During the dehydration step, a dehydration action is performed. Hereinafter, the dehydration operation in the dehydration step is referred to as a final dehydration operation.

以下，針對脫水步驟的最終脫水動作，一邊參照圖6一邊進行說明。Hereinafter, the final dehydration operation in the dehydration step will be described with reference to FIG. 6.

亦即，控制部40在脫水步驟中，首先會進行在沖洗步驟中使用過之洗淨水的排水。That is, in the dehydration step, the control unit 40 first performs drainage of the washing water used in the rinsing step.

具體而言，控制部40會開放排水閥22。藉此，洗淨槽4之內部的洗淨水會從排水孔21通過排水路徑23而排水至外部。此時，控制部40會開啟風量調整閥29，並開放外部氣體導入部28。藉此，洗淨槽4之內部會與外部連通，而導入外部氣體。然後，藉由外部氣體的導入，洗淨水會順利地被排出至外部。此時，第1開閉閥11a、第2開閉閥11b、及脫水排水閥36是關閉的。Specifically, the control unit 40 opens the drain valve 22. As a result, the washing water inside the washing tank 4 is discharged from the drainage hole 21 through the drainage path 23 to the outside. At this time, the control unit 40 opens the air volume adjustment valve 29 and opens the external air introduction unit 28. Thereby, the inside of the washing tank 4 communicates with the outside, and external air is introduced. Then, by the introduction of the external air, the washing water is smoothly discharged to the outside. At this time, the first on-off valve 11a, the second on-off valve 11b, and the dehydration and drainage valve 36 are closed.

排水結束後，控制部40會在最終脫水動作中進行壓縮。亦即，如圖6所示地，控制部40首先會開放排水閥22。然後，控制部40會在關閉第1開閉閥11a及第2開閉閥11b兩者的狀態下，幾乎同時(包含同時)驅動第1加壓泵10a及第2加壓泵10b兩者。藉此，空氣會被供給至第1按壓部8a及第2按壓部8b之內部，且藉由第1按壓部8a及第2按壓部8b的膨脹，被洗淨物2會被按壓而被壓縮。其結果，被洗淨物2所包含之洗淨水的一部分會強制地被排出，並從排水孔21通過排水路徑23而被排水至外部。After the drainage is completed, the control unit 40 performs compression in the final dehydration operation. That is, as shown in FIG. 6, the control unit 40 first opens the drain valve 22. Then, the control unit 40 drives both the first pressure pump 10a and the second pressure pump 10b almost simultaneously (including simultaneously) in a state in which both the first on-off valve 11a and the second on-off valve 11b are closed. Thereby, air is supplied to the inside of the first pressing portion 8a and the second pressing portion 8b, and the expansion of the first pressing portion 8a and the second pressing portion 8b causes the object 2 to be compressed and compressed . As a result, a part of the washing water included in the object to be washed 2 is forcibly discharged, and is discharged to the outside through the drainage hole 21 through the drainage path 23.

亦即，藉由實施形態1的按壓部8的構成及作用，可以使按壓面8c緊貼於被洗淨物2而均勻地按壓。藉此，可以將被洗淨物2之內部所包含之洗淨水強制地擠出。That is, with the configuration and function of the pressing section 8 of the first embodiment, the pressing surface 8c can be pressed closely against the object 2 to be pressed uniformly. Thereby, the washing water contained in the inside of the to-be-cleaned material 2 can be forced out.

壓縮結束後，控制部40會在最終脫水動作中進行吸引。亦即，控制部40會使第1加壓泵10a及第2加壓泵10b停止，並在規定時間T1(例如1分鐘)後，在以按壓部8按壓被洗淨物2的狀態下，關閉排水閥22，並驅動吸引泵27。藉此，洗淨槽4之內部的空氣與水會透過吸引口25、脫水路徑26，而被吸引至氣液分離部30內。因此，藉由吸引，圖4所示之洗淨槽4內會從大氣壓被減壓。然後，被洗淨物2會藉由按壓部8內的壓力與洗淨槽4內的壓力之壓力差而被按壓。After the compression is completed, the control unit 40 performs suction in the final dehydration operation. That is, the control unit 40 stops the first pressure pump 10a and the second pressure pump 10b, and after a predetermined time T1 (for example, one minute), the control unit 40 presses the object 2 to be washed with the pressing unit 8, The drain valve 22 is closed and the suction pump 27 is driven. Thereby, the air and water inside the washing tank 4 pass through the suction port 25 and the dehydration path 26, and are sucked into the gas-liquid separation part 30. Therefore, the inside of the washing tank 4 shown in FIG. 4 is decompressed from atmospheric pressure by suction. Then, the object to be cleaned 2 is pressed by a pressure difference between the pressure in the pressing portion 8 and the pressure in the washing tank 4.

更進一步地，外部氣體會透過風量調整閥29而從外部氣體導入部28被導入洗淨槽4之內部，且外部氣體會侵入被第1按壓部8a及第2按壓部8b按壓過之被洗淨物2之內部。此時，藉由第1加壓泵10a及第2加壓泵10b的驅動而膨脹的第1按壓部8a及第2按壓部8b之內部的壓力，會藉由例如定壓開放閥等而被保持在規定的壓力。因此，被洗淨物2會維持在被一定的壓力加壓的狀態。Furthermore, the outside air passes through the air volume adjustment valve 29 and is introduced into the cleaning tank 4 from the outside air introduction part 28, and the outside air intrudes into the washed part pressed by the first pressing part 8a and the second pressing part 8b. Inside of Net 2. At this time, the internal pressures of the first pressing portion 8a and the second pressing portion 8b, which are expanded by the driving of the first pressure pump 10a and the second pressure pump 10b, are controlled by, for example, a constant pressure release valve. Keep it under pressure. Therefore, the object to be cleaned 2 is maintained in a state of being pressurized by a certain pressure.

又，從外部氣體導入部28被導入洗淨槽4之內部的外部氣體會一邊將留在被洗淨物2的纖維之間之洗淨水擠出，一邊一起被吸引而朝吸引口25移動。此時，藉由外部氣體而被搬運至吸引口25之洗淨水會因為表面張力而留在被洗淨物2的纖維中。但是，藉由因外部氣體的氣流所造成之剪力，洗淨水會從被洗淨物2的纖維分離，並從洗淨槽4的吸引口25通過脫水路徑26而被朝氣液分離部30搬運。The external air introduced into the washing tank 4 from the external air introduction part 28 is sucked together and moves toward the suction port 25 while squeezing the washing water remaining between the fibers of the object 2 to be washed. . At this time, the washing water carried to the suction port 25 by the external air will remain in the fibers of the object 2 due to surface tension. However, due to the shearing force caused by the external air flow, the washing water is separated from the fibers of the object to be washed 2 and is drawn from the suction port 25 of the washing tank 4 through the dewatering path 26 toward the gas-liquid separation section 30. Moving.

而且，從二次側通風口31朝氣液分離部30流入之洗淨水與被吸引的空氣當中，只有空氣會從氣液分離部30之上部的一次側通風口33，藉由吸引泵27而被排出。另一方面，洗淨水會因本身重量而從二次側通風口31落下，並儲水於氣液分離部30的儲水部30a。此時，藉由設置於一次側通風口33與二次側通風口31之間的障壁34，洗淨水朝一次側通風口33的浸入便會被阻止。因此，可以將洗淨水朝吸引泵27的浸入防範於未然。Moreover, among the washing water and the suctioned air flowing from the secondary-side ventilation port 31 toward the gas-liquid separation section 30, only air flows from the primary-side ventilation port 33 above the gas-liquid separation section 30 through the suction pump 27. Be discharged. On the other hand, the washing water falls from the secondary-side vent 31 due to its own weight, and is stored in the water storage section 30 a of the gas-liquid separation section 30. At this time, the barrier 34 provided between the primary air vent 33 and the secondary air vent 31 prevents entry of the washing water into the primary air vent 33. Therefore, infiltration of the washing water into the suction pump 27 can be prevented beforehand.

另外，通常，被吸引的洗淨槽4之內部的洗淨水與空氣會通過阻力最少的路徑。因此，當伴隨著脫水的進行，而在被洗淨物2形成不含洗淨水的短路路徑(short circuit path)時，空氣的流動會集中於所形成的短路路徑，導致洗淨水的吸引變得不會有進展。In addition, in general, the washing water and air inside the suctioned washing tank 4 pass through a path having the least resistance. Therefore, when a short circuit path containing no washing water is formed in the object to be cleaned 2 with the progress of dehydration, the flow of air will concentrate on the formed short circuit path, causing the suction of the washing water. No progress will be made.

然而，在實施形態1的洗衣機1中，被洗淨物2會藉由第1按壓部8a及第2按壓部8b，而隨時被一定的壓力加壓。因此，會抑制上述短路風路的形成。藉此，連同被導入洗淨槽4之內部的外部氣體，洗淨水的吸引脫水會在不停滯的狀態下進行。亦即，實施形態1的洗衣機1會藉由吸引泵27使按壓部8膨脹，以使按壓部8的按壓面8c緊貼於被洗淨物2而均勻地按壓。其結果，外部氣體會被導入被洗淨物2之內部，而可以獲得所欲的脫水性能。However, in the washing machine 1 according to the first embodiment, the object to be washed 2 is pressurized by a certain pressure at any time by the first pressing portion 8a and the second pressing portion 8b. Therefore, the formation of the short-circuit air path is suppressed. Thereby, together with the external air introduced into the inside of the washing tank 4, the suction and dehydration of the washing water is performed without stagnation. That is, the washing machine 1 according to the first embodiment expands the pressing portion 8 by the suction pump 27 so that the pressing surface 8c of the pressing portion 8 is brought into close contact with the object 2 to be pressed uniformly. As a result, external air is introduced into the object to be cleaned 2 and a desired dehydration performance can be obtained.

接著，如圖6所示地，控制部40會將洗淨水與藉由吸引泵27而被導入洗淨槽4之外部氣體，一併吸引規定時間T2(例如4分鐘)。然後，在經過規定時間T2後，控制部40會開啟第1開閉閥11a及第2開閉閥11b，並且停止第1加壓泵10a、第2加壓泵10b、及吸引泵27的驅動。藉此，第1按壓部8a及第2按壓部8b之內部的空氣會透過第1開閉閥11a及第2開閉閥11b而被排出至外部。Next, as shown in FIG. 6, the control unit 40 sucks the washing water together with the external air introduced into the washing tank 4 by the suction pump 27 for a predetermined time T2 (for example, 4 minutes). After a predetermined time T2 has elapsed, the control unit 40 opens the first on-off valve 11a and the second on-off valve 11b, and stops driving of the first pressure pump 10a, the second pressure pump 10b, and the suction pump 27. Thereby, the air inside the 1st pressing part 8a and the 2nd pressing part 8b passes through the 1st on-off valve 11a and the 2nd on-off valve 11b, and is discharged | emitted outside.

然後，被洗淨物2會被解除以第1按壓部8a及第2按壓部8b所進行的按壓，最終脫水動作便結束。Then, the object to be washed 2 is released from the pressing performed by the first pressing portion 8a and the second pressing portion 8b, and the dehydration operation is finally ended.

藉由上述一系列的動作，在脫水步驟結束後，控制部40會將積存於儲水部30a之洗淨水通過脫水排水路徑37排出，來結束洗滌行程。With the series of operations described above, after the dehydration step is completed, the control unit 40 discharges the washing water stored in the water storage unit 30a through the dewatering drainage path 37 to end the washing cycle.

另外，雖然是以圖6來說明了上述最終脫水動作，但在中間脫水動作中亦可進行與圖6同樣的脫水動作。此處，中間脫水動作包含：在沖洗步驟中所進行的中間脫水動作、及在反覆執行複數次的沖洗步驟之間所進行的中間脫水動作。又，上述規定時間T1及規定時間T2在各個中間脫水動作中也是設定為最適當值。Although the above-mentioned final dehydration operation has been described with reference to FIG. 6, the same dehydration operation as in FIG. 6 may be performed in the intermediate dehydration operation. Here, the intermediate dehydration operation includes an intermediate dehydration operation performed in the rinsing step, and an intermediate dehydration operation performed between repeatedly performing a plurality of rinsing steps. The predetermined time T1 and the predetermined time T2 are also set to optimal values in each intermediate dehydration operation.

另外，在圖6的T3中，控制部40進行了使吸引泵27的驅動暫時停止等的動作。這是當儲水部30a中積存於儲水部的洗淨水超過了規定量時的動作。控制部40會將積存於儲水部30a的泡沫與洗淨水排水至機外。然後，在圖6的T4中，控制部40會使吸引泵27再驅動等，來返回至脫水步驟。In T3 in FIG. 6, the control unit 40 performs operations such as temporarily stopping the driving of the suction pump 27. This is an operation when the washing water accumulated in the water storage unit 30a exceeds the predetermined amount. The control unit 40 drains the foam and washing water accumulated in the water storage unit 30a to the outside of the machine. Then, at T4 in FIG. 6, the control unit 40 returns the dehydration step by re-driving the suction pump 27 or the like.

亦即，在清洗步驟後所進行的中間脫水動作及最終脫水動作中，儲水於儲水部30a的洗淨水會隨著各步驟的進行而慢慢地增加。因此，實施形態1中，在脫水動作時，控制部40會以水量偵測部38來監視氣液分離部30的儲水部30a的儲水量。然後，當在以水量偵測部38偵測到超過規定量之洗淨水(水及/或泡沫)的蓄積時，控制部40會停止吸引泵27的驅動並開啟開放閥39。藉此，會與大氣連通，外部氣體便會流入氣液分離部30內。控制部40會幾乎同時(包含同時)將原本關閉的脫水排水閥36開啟。藉此，積存於儲水部30a的泡沫與洗淨水會從脫水排水口35通過脫水排水路徑37而朝外部排水。That is, in the intermediate dehydration operation and the final dehydration operation performed after the washing step, the washing water stored in the water storage unit 30a gradually increases as each step proceeds. Therefore, in the first embodiment, during the dehydration operation, the control section 40 monitors the water storage amount of the water storage section 30 a of the gas-liquid separation section 30 with the water amount detection section 38. Then, when the accumulation of the washing water (water and / or foam) exceeding a predetermined amount is detected by the water amount detecting section 38, the control section 40 stops driving the suction pump 27 and opens the open valve 39. This allows communication with the atmosphere, and external air flows into the gas-liquid separation unit 30. The control unit 40 opens the dehydration and drainage valve 36 that was originally closed almost simultaneously (including simultaneously). As a result, the foam and washing water accumulated in the water storage unit 30 a are discharged from the dewatering drainage port 35 through the dewatering drainage path 37 to the outside.

此時，外部氣體會從已被開啟的開放閥39通過吸引路徑32，而流入已因為吸引泵27的吸引而成為比大氣低的負壓(-P)之氣液分離部30內。藉此，氣液分離部30的內壓會上升。At this time, the outside air passes through the suction path 32 from the opened open valve 39 and flows into the gas-liquid separation unit 30 having a negative pressure (−P) lower than the atmosphere due to the suction by the suction pump 27. Thereby, the internal pressure of the gas-liquid separation part 30 rises.

又，在緊接於清洗步驟後的沖洗步驟的中間脫水動作中，包含多量洗劑成分之洗淨水會被吸引至氣液分離部30的儲水部30a內。此時，藉由洗淨水的吸引，氣液分離部30內的空間體積會減少。藉此，氣液分離部30內的洗淨水會從減壓狀態被加壓。因此，氣液分離部30內的泡沫的體積會減少，就結果而言，包含泡沫之洗淨水的體積會減少。然後，體積減少後的包含泡沫之洗淨水會通過脫水排水路徑37而朝外部排水。藉此，會防止包含泡沫之洗淨水朝吸引泵27內的浸入。Moreover, in the intermediate dehydration operation of the rinsing step immediately after the washing step, the washing water containing a large amount of the detergent component is sucked into the water storage section 30 a of the gas-liquid separation section 30. At this time, the space volume in the gas-liquid separation unit 30 is reduced by the suction of the washing water. Thereby, the washing water in the gas-liquid separation part 30 is pressurized from a reduced pressure state. Therefore, the volume of the foam in the gas-liquid separation section 30 is reduced, and as a result, the volume of the washing water including the foam is reduced. Then, the volume-reduced washing water including the foam is discharged to the outside through the dewatering drainage path 37. This prevents the washing water containing foam from entering the suction pump 27.

更進一步地，在流入氣液分離部30內時，即便從洗淨水飛散的泡沫附著於吸引路徑32內，藉由通過吸引路徑32來流入外部氣體，就可將附著的泡沫推回氣液分離部30內。Furthermore, when flowing into the gas-liquid separation unit 30, even if the foam scattered from the washing water adheres to the suction path 32, and the external air flows in through the suction path 32, the adhered foam can be pushed back to the gas-liquid Inside the separation section 30.

又，藉由外部氣體的導入，已被減壓的氣液分離部30內的壓力便會回復。藉此，泡沫的體積會在短時間內減少。因此，可以在下一次吸引時，防止殘留於氣液分離部30之上部的泡沫侵入吸引泵27。In addition, the pressure in the decompressed gas-liquid separation unit 30 is restored by the introduction of external air. As a result, the volume of the foam is reduced in a short time. Therefore, it is possible to prevent the foam remaining in the upper part of the gas-liquid separation section 30 from entering the suction pump 27 during the next suction.

另外，實施形態1中，是利用：加壓減壓部7是由具有可撓性的按壓部8、將空氣供給至按壓部8之內部而使其膨脹的加壓泵10、及將按壓部8之內部的空氣排出而使其收縮的開閉閥11來構成之例子進行了說明，但並不限於此。亦可作成為例如，取***閉閥11改設置減壓泵，並透過減壓泵來使按壓部8收縮而減壓的構成。更進一步地，藉由使加壓泵10逆轉旋轉，而將加壓泵10作為減壓泵來利用亦可。In addition, in the first embodiment, the pressurizing and decompressing section 7 is a pressurizing section 8 having flexibility, a pressurizing pump 10 that supplies air to the inside of the pressing section 8 to expand it, and a pressing section Although an example in which the on-off valve 11 is exhausted and contracted by the air inside 8 has been described, it is not limited thereto. For example, a configuration may be adopted in which a pressure reducing pump is provided instead of the on-off valve 11, and the pressure portion 8 is contracted and reduced in pressure by the pressure reducing pump. Furthermore, the pressure pump 10 may be used as a pressure reducing pump by rotating the pressure pump 10 in the reverse direction.

又，實施形態1中，作為被供給至按壓部8之內部來使按壓部8膨脹之流體，雖然是以空氣為例子而進行了說明，但並不限於此。亦可為例如，氮氣或氬氣等安全性高的其他氣體，甚至是液體。為氣體的情況下，只要像實施形態1一樣以加壓泵10等將周圍的空氣吸氣即可，又，由於排氣時的限制也會變少，因此在構成等方面上是很方便的。另一方面，為液體的情況下，可以使用例如水、水溶液、或油等。為液體的情況下，若有積存液體的蓄積部，則會更佳。亦即，由於液體的密度比空氣更高，並且彈性不像氣體那麼大，因此可以確實地使按壓部8膨脹。In the first embodiment, the fluid supplied to the inside of the pressing portion 8 to expand the pressing portion 8 has been described using air as an example, but it is not limited to this. It can also be other gases with high safety such as nitrogen or argon, or even liquids. In the case of a gas, it is sufficient to suck in the surrounding air with a pressure pump 10 or the like as in the first embodiment, and the restriction on exhausting will be reduced, so it is convenient in terms of structure and the like. . On the other hand, in the case of a liquid, for example, water, an aqueous solution, or an oil can be used. In the case of a liquid, it is more preferable if there is an accumulation portion that accumulates liquid. That is, since the density of the liquid is higher than that of the air and the elasticity is not as great as that of the gas, the pressing portion 8 can be surely expanded.

如以上地，實施形態1的洗衣機1包含：洗淨槽4，收容被洗淨物2與洗淨水；按壓部8，按壓洗淨槽4內之被洗淨物2；吸引泵27，從被洗淨物2吸引洗淨水；及脫水路徑26，連通連接洗淨槽4與吸引泵27。更進一步地，洗衣機1包含：外部氣體導入部28，將外部氣體導入洗淨槽4內；氣液分離部30，設置於脫水路徑26，並將已從被洗淨物2吸引之洗淨水與空氣分離；及控制部40，控制包含洗衣機的脫水動作之洗滌運轉。氣液分離部30包含：儲水部30a，積存已吸引之洗淨水；水量偵測部38，偵測積存於儲水部30a之洗淨水的量；及開放閥39，使外部氣體流入儲水部30a內。而且，控制部40是構成為在脫水動作中，會藉由按壓部8按壓被洗淨物2，並且藉由吸引泵27吸引洗淨水與被導入之空氣，並在藉由水量偵測部38偵測到規定量後，停止吸引泵27的驅動，使得外部氣體從開放閥39流入儲水部30a內。As described above, the washing machine 1 according to the first embodiment includes the washing tank 4 containing the object to be cleaned 2 and the washing water; the pressing part 8 pressing the object 2 in the washing tank 4; the suction pump 27, The object to be washed 2 sucks the washing water; and the dewatering path 26 communicates with the washing tank 4 and the suction pump 27. Furthermore, the washing machine 1 includes an external air introduction part 28 for introducing external air into the washing tank 4; a gas-liquid separation part 30 provided in the dehydration path 26, and washing water that has been attracted from the object 2 to be washed Separate from the air; and the control unit 40 controls the washing operation including the dehydration operation of the washing machine. The gas-liquid separation section 30 includes: a water storage section 30a that stores the attracted washing water; a water amount detection section 38 that detects the amount of the washing water stored in the water storage section 30a; and an open valve 39 to allow external air to flow in Inside the water storage unit 30a. In addition, the control unit 40 is configured to press the object to be washed 2 by the pressing portion 8 during the dehydration operation, and suck the washing water and the introduced air by the suction pump 27, and the water amount detection portion When a predetermined amount is detected by 38, the driving of the suction pump 27 is stopped, so that external air flows into the water storage unit 30a from the open valve 39.

根據該構成，藉由氣液分離部30內的壓力上升，會使產生的泡沫的體積減少，且在脫水動作時，能夠防止泡沫朝吸引泵27的浸入。又，可透過脫水路徑26，將從被洗淨物2擠出之洗淨水與被導入氣液分離部30之外部氣體一併吸引。因此，對於不適合透過由機械力的作用所造成之清洗或擰擠等洗滌動作來洗滌之被洗淨物2，可以在不施加扭轉等機械力的情況下，良好地執行脫水。According to this configuration, the pressure in the gas-liquid separation unit 30 is increased to reduce the volume of the generated foam, and it is possible to prevent the foam from entering the suction pump 27 during the dehydration operation. In addition, the dewatering path 26 can suck the washing water extruded from the object to be washed 2 together with the external air introduced into the gas-liquid separation unit 30. Therefore, it is possible to perform dehydration well without applying mechanical force such as torsion to the washed object 2 that is not suitable for washing by washing action such as washing or squeezing caused by the action of mechanical force.

又，實施形態1的洗衣機1的加壓部設置於連接氣液分離部30與吸引泵27的吸引路徑32。The pressurizing section of the washing machine 1 according to the first embodiment is provided in a suction path 32 connecting the gas-liquid separation section 30 and the suction pump 27.

根據該構成，可以藉由開放閥39的開放所造成之外部氣體的導入，將飛散而附著於吸引路徑32的泡沫朝氣液分離部30推回。藉此，可以更確實地防止泡沫朝吸引泵27的浸入。With this configuration, it is possible to push the foam that has scattered and adhered to the suction path 32 toward the gas-liquid separation unit 30 by the introduction of external air caused by the opening of the open valve 39. This makes it possible to more reliably prevent the foam from entering the suction pump 27.

又，實施形態1的洗衣機1的加壓部是以開放閥39所構成，前述開放閥39會進行朝儲水部30a內之外部氣體的流入與遮蔽。In addition, the pressurizing section of the washing machine 1 according to the first embodiment is constituted by an open valve 39 that inflows and shields the outside air into the water storage section 30a.

根據該構成，可以藉由開放閥39的開啟，使外部氣體流入氣液分離部30內，並以簡略的構成使氣液分離部30內的壓力上升。藉此，會使產生的泡沫的體積減少，並在脫水動作時，能夠防止泡沫朝吸引泵27的浸入。According to this configuration, by opening the open valve 39, the outside air can flow into the gas-liquid separation unit 30, and the pressure in the gas-liquid separation unit 30 can be increased with a simple structure. This reduces the volume of the generated foam and prevents the foam from entering the suction pump 27 during the dehydration operation.

又，實施形態1的洗衣機1的氣液分離部30包含：脫水排水路徑37，將積存於儲水部30a之洗淨水朝洗衣機外排水；及脫水排水閥36，設置於脫水排水路徑37。而且，控制部40是構成為在外部氣體從開放閥39朝儲水部30a內流入時，會開啟脫水排水閥36。The gas-liquid separation unit 30 of the washing machine 1 according to the first embodiment includes a dewatering drainage path 37 for draining the washing water stored in the water storage unit 30a to the outside of the washing machine, and a dehydration drainage valve 36 provided in the dehydration drainage path 37. The control unit 40 is configured to open the dehydration and drainage valve 36 when external air flows from the open valve 39 into the water storage unit 30a.

根據該構成，可以將氣液分離部30內的泡沫與洗淨水排出至機外，並快速地返回至脫水步驟。藉此，可以防止泡沫朝吸引泵27的浸入，並且可以縮短脫水時間。
(實施形態2)According to this configuration, the foam and the washing water in the gas-liquid separation unit 30 can be discharged to the outside of the machine and quickly returned to the dehydration step. Thereby, it is possible to prevent the foam from entering the suction pump 27 and shorten the dehydration time.
(Embodiment 2)

以下，針對本發明之實施形態2的洗衣機，一邊參照圖7一邊進行說明。Hereinafter, a washing machine according to a second embodiment of the present invention will be described with reference to FIG. 7.

圖7是本發明之實施形態2中的洗衣機1的加壓部的構成圖。FIG. 7 is a configuration diagram of a pressurizing section of the washing machine 1 in Embodiment 2 of the present invention.

實施形態2的洗衣機1在具備具有加壓功能的加壓部42這點上，與實施形態1不同。其他的構成均與實施形態1相同，因此對同樣的構成附加同樣的符號，且詳細的說明援用實施形態1。The washing machine 1 according to the second embodiment is different from the first embodiment in that the washing machine 1 includes a pressurizing section 42 having a pressurizing function. The other configurations are the same as those of the first embodiment. Therefore, the same reference numerals are assigned to the same configurations, and the detailed description will refer to the first embodiment.

亦即，如圖7所示地，實施形態2的加壓部42包含：開放閥39、及送風部42b。開放閥39會依據控制部40的開閉動作指示，進行朝氣液分離部30的儲水部30a內之外部氣體的流入與遮蔽。送風部42b會依據控制部40的驅動指示，將外部氣體送風至儲水部30a內。That is, as shown in FIG. 7, the pressurizing section 42 of the second embodiment includes an open valve 39 and an air blowing section 42 b. The open valve 39 performs inflow and shielding of external air into the water storage unit 30 a of the gas-liquid separation unit 30 in accordance with the opening and closing operation instruction of the control unit 40. The air blowing unit 42b sends external air into the water storage unit 30a according to the driving instruction of the control unit 40.

加壓部42是配置於從連接氣液分離部30與吸引泵27的吸引路徑32分岐的路徑。另外，送風部42b是以例如空氣泵等所構成。The pressurizing section 42 is a path which is divided from a suction path 32 connecting the gas-liquid separation section 30 and the suction pump 27. The air blowing unit 42b is configured by, for example, an air pump.

以下，針對實施形態2中的洗衣機的加壓部42的動作進行說明。The operation of the pressurizing section 42 of the washing machine in the second embodiment will be described below.

首先，在脫水排水閥36的開放時，控制部40會驅動送風部42b，以將外部氣體送風至氣液分離部30的儲水部30a內。藉由被送風之外部氣體，儲水部30a內會被加壓。藉此，蓄積於氣液分離部30的儲水部30a內的泡沫與洗淨水便會迅速地從脫水排水口35朝機外排出。其結果，可以縮短脫水時間，並且可以抑制儲水部30a內的泡沫殘留。First, when the dehydration and drainage valve 36 is opened, the control unit 40 drives the air supply unit 42 b to send external air into the water storage unit 30 a of the gas-liquid separation unit 30. With the external air being blown, the inside of the water storage unit 30a is pressurized. Thereby, the foam and wash water accumulated in the water storage part 30 a of the gas-liquid separation part 30 are quickly discharged from the dewatering drainage port 35 to the outside of the machine. As a result, the dehydration time can be shortened, and the foam remaining in the water storage unit 30a can be suppressed.

如以上所說明地，本發明的洗衣機包含：洗淨槽，收容被洗淨物與洗淨水；按壓部，按壓洗淨槽內之被洗淨物；吸引部，從被洗淨物吸引洗淨水；及脫水路徑，連通連接洗淨槽與吸引部。更進一步地，洗衣機包含：外部氣體導入部，將外部氣體導入洗淨槽內；氣液分離部，設置於脫水路徑，並將已從被洗淨物吸引之洗淨水與空氣分離；及控制部，控制包含洗衣機的脫水動作之洗滌運轉。氣液分離部包含：儲水部，積存已吸引之洗淨水；水量偵測部，偵測積存於儲水部之洗淨水的量；及加壓部，使外部氣體流入儲水部內。而且，控制部是構成為在脫水動作中，會藉由按壓部按壓被洗淨物，並且藉由吸引部吸引洗淨水與空氣，並在藉由水量偵測部偵測到積存於儲水部之洗淨水成為規定量後，停止吸引部的驅動，並藉由加壓部使外部氣體流入儲水部內。As described above, the washing machine of the present invention includes: a washing tank that houses the object to be washed and washing water; a pressing part that presses the object to be washed in the washing tank; and a suction part that sucks and cleans the object from the object to be washed Water purification; and a dehydration path, which connects the washing tank and the suction part. Furthermore, the washing machine includes: an external air introduction part to introduce external air into the washing tank; a gas-liquid separation part provided in the dehydration path, and separating washing water that has been attracted from the object to be cleaned from the air; and control The unit controls a washing operation including a dehydration operation of the washing machine. The gas-liquid separation section includes: a water storage section that stores the attracted washing water; a water amount detection section that detects the amount of the washing water stored in the water storage section; and a pressurizing section that allows external air to flow into the water storage section. In addition, the control unit is configured to press the object to be washed by the pressing portion during the dehydration operation, and suck the washing water and air by the suction portion, and the water amount detection portion detects that it is accumulated in the water storage After the washing water in the part reaches a predetermined amount, the driving of the suction part is stopped, and the external air flows into the water storage part through the pressurizing part.

根據該構成，在脫水動作時，氣液分離部的儲水部會對大氣開放，已因為吸引而成為負壓的儲水部內的壓力便會上升。藉此，會使產生的泡沫的體積減少，能夠防止泡沫朝吸引部的浸入。又，可透過脫水路徑，將從被洗淨物擠出之洗淨水與被導入氣液分離部之外部氣體一併吸引。因此，對於不適合透過由機械力的作用所造成之清洗或擰擠等洗滌動作來洗滌之被洗淨物，可以在不施加扭轉等機械力的情況下，良好地執行脫水。According to this configuration, during the dehydration operation, the water storage section of the gas-liquid separation section is opened to the atmosphere, and the pressure in the water storage section that has become negative pressure due to suction increases. Thereby, the volume of the generated foam is reduced, and it is possible to prevent the foam from entering the suction portion. Moreover, it is possible to suck the washing water extruded from the object to be cleaned together with the external air introduced into the gas-liquid separation part through the dehydration path. Therefore, for objects to be washed that are not suitable for washing by washing action such as washing or squeezing caused by the action of mechanical force, dehydration can be performed well without applying mechanical force such as torsion.

又，本發明的洗衣機以在加壓部設置連接氣液分離部與吸引部的吸引路徑的構成為佳。The washing machine of the present invention preferably has a configuration in which a suction path that connects the gas-liquid separation section and the suction section is provided in the pressurizing section.

根據該構成，可以藉由加壓部的開放所造成之外部氣體的導入，將飛散而附著於吸引路徑的泡沫朝氣液分離部推回。藉此，可以更確實地防止泡沫朝吸引部的浸入。With this configuration, it is possible to push the foam that has scattered and adhered to the suction path by the introduction of external air caused by the opening of the pressurizing section toward the gas-liquid separation section. This makes it possible to more reliably prevent the foam from entering the suction portion.

又，本發明的洗衣機的加壓部宜由開放閥來構成為佳，前述開放閥會進行朝儲水部內之外部氣體的流入與遮蔽。The pressurizing section of the washing machine of the present invention is preferably constituted by an open valve, and the open valve performs inflow and shielding of external air into the water storage section.

根據該構成，可以藉由開放閥的開啟，使外部氣體流入氣液分離部內，並以簡略的構成使氣液分離部內的壓力上升。藉此，會使產生的泡沫的體積減少，並在脫水動作時，能夠防止泡沫朝吸引部的浸入。According to this configuration, by opening the open valve, external air can flow into the gas-liquid separation section, and the pressure in the gas-liquid separation section can be increased with a simple configuration. Thereby, the volume of the generated foam is reduced, and it is possible to prevent the foam from entering the suction portion during the dehydration operation.

又，本發明的洗衣機的氣液分離部包含：脫水排水路徑，將積存於儲水部之洗淨水朝洗衣機外排水；及脫水排水閥，設置於脫水排水路徑。而且，控制部宜構成為在外部氣體從加壓部朝儲水部內流入時，會開啟脫水排水閥為佳。The gas-liquid separation section of the washing machine of the present invention includes a dewatering and drainage path for draining the washing water stored in the water storage section toward the outside of the washing machine; and a dehydration and drainage valve provided on the dehydration and drainage path. Furthermore, it is preferable that the control section is configured to open the dehydration and drainage valve when external air flows from the pressurizing section into the water storage section.

根據該構成，可以將氣液分離部內的泡沫與洗淨水排出至機外，並快速地返回至脫水步驟。藉此，可以防止泡沫朝吸引部的浸入，並且可以縮短脫水時間。According to this configuration, the foam and the washing water in the gas-liquid separation section can be discharged to the outside of the machine and quickly returned to the dehydration step. Thereby, it is possible to prevent the foam from penetrating into the suction portion, and to shorten the dehydration time.

又，本發明的洗衣機的加壓部更包含：送風部，將外部氣體送風至儲水部內，控制部宜構成為在脫水排水閥的開放時，會驅動送風部為佳。In addition, the pressurizing part of the washing machine of the present invention further includes a blower part that blows outside air into the water storage part, and the control part is preferably configured to drive the blower part when the dehydration drain valve is opened.

根據該構成，可以將氣液分離部內的泡沫與洗淨水迅速地朝機外排出。藉此，可以縮短脫水時間，並且可以抑制氣液分離部內的泡沫殘留。With this configuration, the foam and the washing water in the gas-liquid separation section can be quickly discharged to the outside of the machine. Thereby, the dehydration time can be shortened, and the foam remaining in the gas-liquid separation section can be suppressed.
