[發明所欲解決之課題][The problem that the invention wants to solve]
在專利文獻1記載之冰箱中，由臭氧生成裝置200生成之臭氧供給至蔬果保鮮室120(段落0038)。因此，臭氧不供給至冷藏室110。在專利文獻2記載之實施形態1之冰箱中，臭氧供給至冷藏室52(段落0049)。然而，在該實施形態1之冰箱中，雖然藉由冷藏室用冷卻器56產生之冷氣自外部冷卻蔬果保鮮室53，但包含臭氧之冷氣不供給至蔬果保鮮室53。因此，在專利文獻1及2記載之冰箱中，可發揮臭氧之效果之儲藏室有限定性。 本揭示所欲解決之課題在於提供一種可向使用者充分地賦予臭氧之效果之冰箱。 [解決課題之技術手段] In the refrigerator described in Patent Document 1, ozone generated by the ozone generating device 200 is supplied to the fruit and vegetable fresh-keeping room 120 (paragraph 0038). Therefore, ozone is not supplied to the refrigerator 110. In the refrigerator of Embodiment 1 described in Patent Document 2, ozone is supplied to the refrigerator 52 (paragraph 0049). However, in the refrigerator of Embodiment 1, although the cold air generated by the refrigerator 56 cools the fruit and vegetable fresh-keeping room 53 from the outside, the cold air containing ozone is not supplied to the fruit and vegetable fresh-keeping room 53. Therefore, in the refrigerators described in Patent Documents 1 and 2, the storage room where the effect of ozone can be exerted is limited. The problem to be solved by this disclosure is to provide a refrigerator that can fully give the effect of ozone to the user. [Technical means for solving the problem]
本揭示之冰箱包含：第1儲藏室，其係可儲藏食品之冷藏室或冷鮮室之至少一者；冷卻器，其產生冷氣；供給口，其將前述冷卻器產生之冷氣供給至前述第1儲藏室；返回口，其將冷卻前述第1儲藏室之冷氣導引至前述冷卻器；及臭氧生成器，其向由前述冷卻器產生之冷氣之氣流供給臭氧；且藉由前述冷卻器產生之冷氣不供給至冷凍溫度帶之第2儲藏室，且不冷卻可儲藏蔬果、較前述第1儲藏室為高溫之蔬果保鮮室，或除了前述第1儲藏室以外亦對前述蔬果保鮮室供給。其他解決手段在用於實施發明之形態中將於後述。The refrigerator disclosed herein includes: a first storage chamber, which is at least one of a refrigeration chamber or a fresh-keeping chamber for storing food; a cooler, which generates cold air; a supply port, which supplies the cold air generated by the cooler to the first storage chamber; a return port, which guides the cold air used to cool the first storage chamber to the cooler; and an ozone generator, which supplies ozone to the airflow of the cold air generated by the cooler; and the cold air generated by the cooler is not supplied to the second storage chamber in the freezing temperature zone, and is not cooled to the fruit and vegetable fresh-keeping chamber which can store fruits and vegetables and is at a higher temperature than the first storage chamber, or is supplied to the fruit and vegetable fresh-keeping chamber in addition to the first storage chamber. Other solutions will be described later in the form used to implement the invention.

In the description of one of the following implementation forms, descriptions of other implementation forms applicable to one implementation form will also be appropriately made. The present disclosure is not limited to one of the following implementation forms, and different implementation forms may be combined with each other, or arbitrarily changed within the scope that does not obviously damage the effect of the present disclosure. In addition, the same symbols are given to the same components, and repeated descriptions are omitted. Furthermore, those with the same functions are also given the same names. The contents of the diagrams are ultimately for illustration only. For the convenience of illustration, there may be changes from the actual structure within the scope that does not obviously damage the effect of the present disclosure, or the illustration of some components may be omitted between the drawings.
圖1係本揭示之冰箱1之前視圖。冰箱1自上起依序包含：冷藏室2(圖2)、蔬果保鮮室3(圖2)、左右配置之製冰室(未圖示)及第1冷凍室5(圖2)、以及第2冷凍室6(圖2)。冰箱1之進一步之詳情將一面參照圖2而於後述，在冷藏室2之下部包含冷鮮室7(圖2)。冷藏室2、蔬果保鮮室3、製冰室、第1冷凍室5及第2冷凍室6分別在前方(正面側)具有開口(未圖示)。FIG. 1 is a front view of the refrigerator 1 of the present disclosure. The refrigerator 1 includes, from the top, a refrigerating chamber 2 (FIG. 2), a fruit and vegetable preservation chamber 3 (FIG. 2), an ice-making chamber (not shown) arranged on the left and right, a first freezing chamber 5 (FIG. 2), and a second freezing chamber 6 (FIG. 2). The refrigerator 1 will be described in further detail with reference to FIG. 2. A fresh-keeping chamber 7 (FIG. 2) is included below the refrigerating chamber 2. The refrigerating chamber 2, the fruit and vegetable preservation chamber 3, the ice-making chamber, the first freezing chamber 5, and the second freezing chamber 6 have openings (not shown) at the front (front side) respectively.
門2a、2b藉由其轉動，而將冷藏室2之開口露出或閉塞。門2a、2b以沿鉛直方向延伸之轉動軸為軸中心而轉動。門3a、4a、5a、6a分別藉由其等之拉出或推入，而將蔬果保鮮室3、製冰室、第1冷凍室5及第2冷凍室6之開口露出或閉塞。The doors 2a and 2b are rotated to expose or close the opening of the refrigerating chamber 2. The doors 2a and 2b are rotated with the rotation axis extending in the vertical direction as the axis center. The doors 3a, 4a, 5a, and 6a are pulled out or pushed in respectively to expose or close the openings of the fruit and vegetable preservation chamber 3, the ice making chamber, the first freezing chamber 5, and the second freezing chamber 6.
圖2係圖1之A-A線剖視圖。在圖2中，實線箭頭表示由冷卻器41、51產生之冷氣流。再者，在圖2之例中，冷卻器41係不是將冷凍溫度帶之儲藏室包含於冷氣供給範圍、而是將冷藏溫度帶之儲藏室設為冷氣供給範圍之冷藏帶冷卻器。又，在圖2之例中，冷卻器51係不是將冷藏溫度帶之儲藏室包含於冷氣供給範圍、而是將冷凍溫度帶之儲藏室設為冷氣供給範圍之冷凍區冷卻器。FIG. 2 is a cross-sectional view taken along line A-A of FIG. 1. In FIG. 2, the solid arrows indicate the cold air flow generated by the coolers 41 and 51. Furthermore, in the example of FIG. 2, the cooler 41 is a refrigerated zone cooler that does not include the storage room in the freezing temperature zone in the cold air supply range, but sets the storage room in the refrigerated temperature zone as the cold air supply range. Furthermore, in the example of FIG. 2, the cooler 51 is a freezing zone cooler that does not include the storage room in the refrigerated temperature zone in the cold air supply range, but sets the storage room in the freezing temperature zone as the cold air supply range.
冷藏室2(第1儲藏室)係可儲藏肉、魚等食品之室。此處所言之第1儲藏室係冷藏室2或冷鮮室7(後述)之至少一者，在本揭示之例中為冷藏室2及冷鮮室7。冷藏室2固定於冷藏溫度帶。冷藏室2之溫度例如作為門2a、2b關閉之狀態之平均溫度，為並不限定於該數值範圍之例如2°C以上4°C以下。冷藏室2具備可載置食品之複數個擱架21。The refrigerating chamber 2 (first storage chamber) is a chamber for storing food such as meat and fish. The first storage chamber mentioned here is at least one of the refrigerating chamber 2 and the fresh-keeping chamber 7 (described later), and in the example disclosed herein, it is the refrigerating chamber 2 and the fresh-keeping chamber 7. The refrigerating chamber 2 is fixed in a refrigerating temperature zone. The temperature of the refrigerating chamber 2 is, for example, an average temperature when the doors 2a and 2b are closed, which is not limited to the numerical range, for example, 2°C or more and 4°C or less. The refrigerating chamber 2 has a plurality of shelves 21 on which food can be placed.
圖3係顯示冷藏室2之內部之自正面側之立體圖。擱架21在上下方向上排列而配置複數個。在冷藏室2之內部之左右側壁，配置有支持擱架21之肋27。冰箱1具備將冷卻器41(圖2)產生之冷氣向冷藏室2(第1儲藏室)供給冷氣之供給口24。詳情將於後述，因冷鮮室7之密閉度不太高，故供給至冷藏室2之冷氣亦多少供給至冷鮮室7。因此，供給口24向上述第1儲藏室供給冷氣。供給口24形成於構成冷藏室2之背面壁(內壁)之背面面板20。詳情將於後述，自供給口24供給之冷氣係冷卻器41(圖2)產生者。又，在被供給之冷氣中，包含由臭氧生成器42(圖2)生成之臭氧(後述)。FIG. 3 is a perspective view showing the interior of the refrigerating chamber 2 from the front side. A plurality of shelves 21 are arranged in an up-down direction. Ribs 27 for supporting the shelves 21 are arranged on the left and right side walls of the interior of the refrigerating chamber 2. The refrigerator 1 is provided with a supply port 24 for supplying the cold air generated by the cooler 41 (FIG. 2) to the refrigerating chamber 2 (the first storage chamber). As will be described in detail later, since the airtightness of the fresh-keeping chamber 7 is not too high, the cold air supplied to the refrigerating chamber 2 is also supplied to the fresh-keeping chamber 7 to a certain extent. Therefore, the supply port 24 supplies cold air to the above-mentioned first storage chamber. The supply port 24 is formed on a back panel 20 constituting the back wall (inner wall) of the refrigerating chamber 2. As will be described in detail later, the cold air supplied from the supply port 24 is generated by the cooler 41 (FIG. 2). Furthermore, the supplied cold air includes ozone (described later) generated by the ozone generator 42 ( FIG. 2 ).
供給口24將冷卻器41產生之冷氣首先供給至冷藏室2。在本揭示之例中，上述第1儲藏室至少包含冷藏室2。而且，供給口24包含：第1供給口22，其設置於相鄰之擱架21之間；及第2供給口23，其設置於較最上段之擱架21靠上方。第2供給口23亦可設置於冷藏室2之頂面。包含臭氧之冷氣經由第1供給口22及第2供給口23供給至冷藏室2。藉此，亦可對最上段之擱架21之上方供給臭氧。因臭氧較空氣重，故自最上段之擱架21供給之冷氣所含之臭氧在供給後往向冷藏室2之下方。藉此，使臭氧遍布於冷藏室2之整體，而可在冷藏室2之整體發揮臭氧之除菌(殺菌)效果及脫臭效果。The supply port 24 first supplies the cold air generated by the cooler 41 to the cold storage room 2. In the example of the present disclosure, the above-mentioned first storage room at least includes the cold storage room 2. Moreover, the supply port 24 includes: a first supply port 22, which is arranged between adjacent shelves 21; and a second supply port 23, which is arranged above the uppermost shelf 21. The second supply port 23 can also be arranged on the top surface of the cold storage room 2. The cold air containing ozone is supplied to the cold storage room 2 through the first supply port 22 and the second supply port 23. In this way, ozone can also be supplied to the upper part of the uppermost shelf 21. Because ozone is heavier than air, the ozone contained in the cold air supplied from the uppermost shelf 21 moves to the lower part of the cold storage room 2 after supply. Thereby, ozone is spread throughout the entire refrigerating chamber 2, and the sterilization (sterilization) effect and deodorization effect of ozone can be exerted in the entire refrigerating chamber 2.
圖4係區劃冷藏室2之背面側之背面面板20之前視圖。供給口24如上述般形成於背面面板20。供給口24以沿水平方向開口之方式朝向正面側及左右方向分別各形成2個，以沿鉛直方向開口之方式面向上側形成1個。又，在背面面板20之下側，形成有將冷藏室2及蔬果保鮮室3之冷氣返回冷卻器41(圖2)之返回口25、34。FIG. 4 is a front view of the back panel 20 that demarcates the back side of the refrigerating chamber 2. The supply port 24 is formed on the back panel 20 as described above. Two supply ports 24 are formed in a horizontal direction toward the front side and the left and right directions, and one is formed in a vertical direction toward the upper side. In addition, return ports 25 and 34 are formed on the lower side of the back panel 20 to return the cold air of the refrigerating chamber 2 and the fruit and vegetable preservation chamber 3 to the cooler 41 (FIG. 2).
圖5係背面面板20之後視圖。在背面面板20之背面側形成有流路26。自返回口25、34吸入之空氣藉由風扇43之驅動而沿鉛直上方向流過流路26。藉由冷卻器41產生之冷氣流過流路26，經由供給口24供給至冷藏室2。FIG5 is a rear view of the rear panel 20. A flow path 26 is formed on the rear side of the rear panel 20. The air sucked from the return ports 25 and 34 flows through the flow path 26 in a straight upward direction driven by the fan 43. The cold air generated by the cooler 41 flows through the flow path 26 and is supplied to the refrigerating chamber 2 through the supply port 24.
圖6係自背面側觀察背面面板20之立體圖。在區劃流路26之壁面，配置有臭氧生成器42。臭氧生成器42係向由冷卻器41產生之冷氣之氣流供給臭氧者，詳情將於後述，藉由冷氣中之放電而在冷氣中生成臭氧。臭氧生成器42配置於複數個供給口24中之最下側之供給口29與風扇43(圖5)之間。藉由如此般配置，可使自所有供給口24供給之冷氣分別包含臭氧。又，臭氧生成器42以埋沒於區劃流路26之壁面之方式配置，開口428(圖7A、圖7B)面向流路26。FIG6 is a three-dimensional view of the back panel 20 as viewed from the back side. An ozone generator 42 is arranged on the wall surface of the partitioned flow path 26. The ozone generator 42 supplies ozone to the airflow of the cold air generated by the cooler 41. The details will be described later. The ozone generator 42 generates ozone in the cold air by discharge in the cold air. The ozone generator 42 is arranged between the lowest supply port 29 of the plurality of supply ports 24 and the fan 43 (FIG. 5). By such an arrangement, the cold air supplied from all the supply ports 24 can contain ozone respectively. In addition, the ozone generator 42 is arranged in a manner buried in the wall surface of the partitioned flow path 26, and the opening 428 (FIG. 7A, FIG. 7B) faces the flow path 26.
返回圖2，在冷藏室2之內部在下部配置有冷鮮室7。冷鮮室7係固定為例如食品在即將結冰之前之冷藏溫度帶、而可儲藏食品之室。冷鮮室7構成為在正面具有開口(未圖示)，可藉由門(未圖示)而閉塞該開口。冷鮮室7之溫度例如作為該門關閉之狀態之平均溫度，為並不限定於該數值範圍之例如-3°C以上4°C以下。Returning to FIG. 2 , a fresh-keeping room 7 is disposed at the lower part of the refrigerator compartment 2. The fresh-keeping room 7 is a room that is fixed to a refrigeration temperature zone, for example, before the food is about to freeze, and can store food. The fresh-keeping room 7 is configured to have an opening (not shown) on the front, and the opening can be closed by a door (not shown). The temperature of the fresh-keeping room 7 is, for example, an average temperature when the door is closed, which is not limited to the numerical range, for example, above -3°C and below 4°C.
冷鮮室7藉由在與冷藏室2之間可通過氣體之程度之氣密性而自冷藏室2區劃出，在冷藏室2之內部配置於下部。因此，詳情將於後述，充滿於冷藏室2之臭氧通過自冷藏室2區劃冷鮮室7之構件71之間隙，擴散至冷鮮室7之內部。又，冷鮮室7之內部之冷氣通過構件71之間隙而返回冷藏室2。The fresh-keeping room 7 is separated from the refrigerating room 2 by airtightness to the extent that gas can pass therebetween, and is arranged at the lower part inside the refrigerating room 2. Therefore, as will be described in detail later, the ozone filled in the refrigerating room 2 diffuses into the inside of the fresh-keeping room 7 through the gap of the component 71 separating the fresh-keeping room 7 from the refrigerating room 2. In addition, the cold air inside the fresh-keeping room 7 returns to the refrigerating room 2 through the gap of the component 71.
在冷藏室2之背面側，設置產生冷氣之冷卻器41。冷卻器41設置於冰箱1。冷卻器41如上述般產生向非為冷凍溫度帶之儲藏室(食品不結冰之冷藏溫度帶之儲藏室)供給之冷氣。冷卻器41係溫度設定成冷藏溫度帶之儲藏室之冷卻所需之充分之程度(例如為-18°C以上，但並不限定於該數值範圍)之冷卻器。因此，與設定成冷凍溫度帶之冷卻器51相比，容易將冷藏室2及冷鮮室7之內部設為高濕，且容易設為適宜於冷藏室2及冷鮮室7之冷卻之範圍之低溫。特別是，若臭氧發揮作用之區域愈為高濕，則臭氧之除菌及脫臭效果愈優異。因此，藉由將冷藏室2及冷鮮室7之內部形成為高濕，而可充分地發揮該等之效果。A cooler 41 for generating cold air is provided on the back side of the refrigerating chamber 2. The cooler 41 is provided in the refrigerator 1. As described above, the cooler 41 generates cold air for supply to a storage chamber that is not in a freezing temperature zone (a storage chamber in a refrigerating temperature zone where food does not freeze). The cooler 41 is a cooler whose temperature is set to a sufficient degree required for cooling a storage chamber in a refrigerating temperature zone (for example, above -18°C, but not limited to this numerical range). Therefore, compared with the cooler 51 set to a freezing temperature zone, it is easy to set the interior of the refrigerating chamber 2 and the fresh-keeping chamber 7 to a high humidity, and it is easy to set the temperature to a low temperature suitable for cooling the refrigerating chamber 2 and the fresh-keeping chamber 7. In particular, the higher the humidity of the area where ozone works, the better the sterilization and deodorization effect of ozone. Therefore, by forming the interior of the refrigerating chamber 2 and the fresh-keeping chamber 7 into a high humidity, these effects can be fully exerted.
冷卻器41配置於背面面板20之背面側。冷卻器41收容於配置在背面面板20之背面側之室44。冰箱1設置將冷卻冷藏室2(第1儲藏室)之冷氣到導引至冷卻器41之返回口25。上述第1儲藏室至少包含冷藏室2，返回口25包含設置於冷藏室2之返回口28(冷藏室返回口)。返回口28例如設置於冷藏室2之背面側。經由返回口28排出至冰箱1之外之冷氣經由蔬果保鮮室3返回冷卻器41。The cooler 41 is arranged on the back side of the back panel 20. The cooler 41 is housed in a chamber 44 arranged on the back side of the back panel 20. The refrigerator 1 is provided with a return port 25 for guiding the cold air of the cold storage chamber 2 (the first storage chamber) to the cooler 41. The first storage chamber at least includes the cold storage chamber 2, and the return port 25 includes a return port 28 (cold storage chamber return port) provided in the cold storage chamber 2. The return port 28 is provided, for example, on the back side of the cold storage chamber 2. The cold air discharged to the outside of the refrigerator 1 through the return port 28 returns to the cooler 41 through the fruit and vegetable preservation chamber 3.
在冷卻器41之上方(在冷氣氣流中為下游側)，設置有風扇43。風扇43例如為離心風扇 ，設置於冰箱1。風扇43經由形成於冷藏室2之供給口24及返回口25，使包含臭氧之冷氣在冷藏室2之內外循環。A fan 43 is provided above the cooler 41 (on the downstream side in the cold air flow). The fan 43 is, for example, a centrifugal fan and is provided in the refrigerator 1. The fan 43 circulates the cold air containing ozone inside and outside the cold room 2 through the supply port 24 and the return port 25 formed in the cold room 2.
經由供給口24供給至冷藏室2之冷氣如上述般往向自上向下之方向。因冷鮮室7設置於冷藏室2之下部，故在冷氣往向返回口25時，與冷鮮室7之至少上表面(在本揭示之例中為至少上下表面)接觸。藉此，冷氣冷卻冷藏室2及冷鮮室7。如此般冷卻冷藏室2及冷鮮室7(第1儲藏室)之冷氣經由返回口25導引至冷卻器41。The cold air supplied to the refrigerating chamber 2 through the supply port 24 flows in the direction from top to bottom as described above. Since the fresh food compartment 7 is disposed at the lower part of the refrigerating chamber 2, when the cold air flows toward the return port 25, it contacts at least the upper surface (at least the upper and lower surfaces in the example disclosed herein) of the fresh food compartment 7. Thus, the cold air cools the refrigerating chamber 2 and the fresh food compartment 7. The cold air that cools the refrigerating chamber 2 and the fresh food compartment 7 (the first storage chamber) is guided to the cooler 41 through the return port 25.
在風扇43之上方(冷氣氣流中為下游側)，設置臭氧生成器42。臭氧生成器42設置於冰箱1。臭氧生成器42在由冷卻器41產生之冷氣之流動方向上，配置於冷卻器41與返回口25之間。An ozone generator 42 is provided above the fan 43 (on the downstream side in the cold air flow). The ozone generator 42 is provided in the refrigerator 1. The ozone generator 42 is disposed between the cooler 41 and the return port 25 in the flow direction of the cold air generated by the cooler 41.
在本揭示之例中，臭氧生成器42如參照上述圖5及圖6所說明般，設置於冷卻器41與供給口24之間。其中，臭氧生成器42設置於冷卻器41與向複數個供給口24之分支部分(即較最下側之供給口24更靠下側)之間。基於不向風扇43供給高濃度之臭氧之觀點，亦可設為較風扇43靠下游。因此，自供給口24供給有包含臭氧之冷氣。藉由設置在如此之位置，而可向供給至冷藏室2及冷鮮室7之前之冷氣放出臭氧。In the example disclosed herein, the ozone generator 42 is disposed between the cooler 41 and the supply port 24 as described with reference to the above-mentioned FIG. 5 and FIG. 6 . The ozone generator 42 is disposed between the cooler 41 and the branch portion to the plurality of supply ports 24 (i.e., lower than the supply port 24 at the lowermost side). From the viewpoint of not supplying high-concentration ozone to the fan 43, it may also be disposed downstream of the fan 43. Therefore, cold air containing ozone is supplied from the supply port 24. By being disposed in such a position, ozone can be released to the cold air before being supplied to the refrigerating chamber 2 and the fresh-keeping chamber 7.
在冷卻器41與供給口24之間流動之冷氣為了被冷卻器41冷卻，與冷藏室2、冷鮮室7等相比為低溫低濕。臭氧生成器42之臭氧之生成量較佳的是產生之區域為低溫低濕，因此，可增大臭氧生成量，且可容易在冷藏室2及冷鮮室7整體將臭氧設為高濃度。The cold air flowing between the cooler 41 and the supply port 24 is cooled by the cooler 41 and has a lower temperature and humidity than the refrigerating chamber 2 and the fresh-keeping chamber 7. The ozone generated by the ozone generator 42 is preferably generated in a region with a lower temperature and humidity, so the ozone generation amount can be increased and the ozone concentration can be easily set to a high level in the refrigerating chamber 2 and the fresh-keeping chamber 7 as a whole.
更佳的是，臭氧生成器42在冷卻器41之動作中(冷卻動作中)生成臭氧。亦即，在冷卻器41作為冷媒循環之冷凍循環之一構件而配置之情形下，動作中係低溫冷媒流通至冷卻器41之期間。又，在冷卻器41為珀爾帖元件之情形下，動作中為通電中。藉由在冷卻器41之動作中生成臭氧，而可在因動作而成為低溫之冷氣中生成臭氧，故可增大臭氧生成量。More preferably, the ozone generator 42 generates ozone during the operation of the cooler 41 (during cooling operation). That is, when the cooler 41 is configured as a component of a refrigeration cycle of a refrigerant cycle, the operation is a period when a low-temperature refrigerant flows to the cooler 41. In addition, when the cooler 41 is a Peltier element, the operation is when power is supplied. By generating ozone during the operation of the cooler 41, ozone can be generated in the cold air that has become low temperature due to the operation, so the amount of ozone generated can be increased.
又，臭氧生成器42於在冷卻器41不進行冷卻動作之狀態下生成臭氧時，可使後述之加熱器423作動。即，臭氧生成器42在冷卻器41之非動作中一面使加熱器423動作一面生成臭氧。所謂不進行冷卻動作之狀態(即非動作中)係指冷卻器41在作為冷媒循環之冷凍循環之一構件而配置之情形下，通常為冷媒之循環停止之狀態。又，在冷卻器41為珀爾帖元件之情形下，不進行冷卻動作之狀態為通電停止中。Furthermore, when the ozone generator 42 generates ozone while the cooler 41 is not performing cooling operation, the heater 423 described later can be operated. That is, the ozone generator 42 generates ozone while the heater 423 is operated while the cooler 41 is not operating. The so-called state of not performing cooling operation (i.e., not operating) refers to the state in which the cooler 41 is configured as a component of the refrigeration cycle of the refrigerant circulation, and the circulation of the refrigerant is usually stopped. Furthermore, in the case where the cooler 41 is a Peltier element, the state of not performing cooling operation is the state of power-off.
如此之臭氧生成器42之動作在臭氧生成器42周圍不被冷卻器41低濕化之情況下有效。特別是，為了確保臭氧之生成量，較佳的是在臭氧生成器42或其附近不產生結露。若在冷卻器41未進行冷卻動作之狀態下打開冷藏室2之門2a、2b，則有高濕之外部大氣到達臭氧生成器42之虞。因此，因使相對濕度下降而不易產生結露，故如此實施為較佳。亦可使用檢測門2a、2b打開之感測器資訊，相應於打開檢測而使加熱器423作動。Such an operation of the ozone generator 42 is effective when the surrounding of the ozone generator 42 is not dehumidified by the cooler 41. In particular, in order to ensure the amount of ozone generated, it is better not to generate condensation on the ozone generator 42 or in its vicinity. If the doors 2a, 2b of the cold storage room 2 are opened when the cooler 41 is not performing a cooling operation, there is a risk that high-humidity external air will reach the ozone generator 42. Therefore, it is better to implement it in this way because it is not easy to generate condensation due to the decrease in relative humidity. It is also possible to use sensor information that detects the opening of the doors 2a, 2b, and activate the heater 423 in response to the opening detection.
惟，臭氧生成器42較佳的是設置於冷藏室2或冷鮮室7之至少一者之內部。藉此，可在抑制臭氧分解之狀態下，使由臭氧生成器42生成之臭氧迅速地遍布於冷藏室2或冷鮮室7之至少一者之整體。其結果，可充分地發揮臭氧之除菌及脫臭效果。However, the ozone generator 42 is preferably installed inside at least one of the refrigerating chamber 2 or the fresh food chamber 7. In this way, the ozone generated by the ozone generator 42 can be quickly distributed throughout at least one of the refrigerating chamber 2 or the fresh food chamber 7 while suppressing the decomposition of ozone. As a result, the sterilization and deodorization effects of ozone can be fully exerted.
圖7A係臭氧生成器42之俯視圖。圖7B係圖7A之B-B線剖視圖。在圖7A中，為了便於圖示，而省略絕緣層425之圖示。臭氧生成器42包含：基板422、加熱器423、電極424、及絕緣層425。電極424包含感應電極426及放電電極427。基板422、加熱器423、感應電極426、放電電極427、及絕緣層425以特定間隔隔開，但該等藉由絕緣構件(未圖示)而相互固定。基板422、加熱器423、電極424、及絕緣層425收容在具備開口428之殼體421中。FIG. 7A is a top view of the ozone generator 42. FIG. 7B is a cross-sectional view taken along line B-B of FIG. 7A. In FIG. 7A, the insulating layer 425 is omitted for ease of illustration. The ozone generator 42 includes a substrate 422, a heater 423, an electrode 424, and an insulating layer 425. The electrode 424 includes a sensing electrode 426 and a discharge electrode 427. The substrate 422, the heater 423, the sensing electrode 426, the discharge electrode 427, and the insulating layer 425 are separated by a specific interval, but are fixed to each other by an insulating member (not shown). The substrate 422 , the heater 423 , the electrode 424 , and the insulating layer 425 are housed in a housing 421 having an opening 428 .
基板422供搭載用於自電極424高壓放電之電源電路(未圖示)等。電源電路由控制裝置100(圖2)控制。因此，控制裝置100控制電源電路而控制放電。電極424藉由在空氣中(冷氣中)放電而生成臭氧。藉由在被施加高壓電壓之放電電極427、與接地連接之感應電極426之間例如進行沿面放電，而在感應電極426與放電電極427之間生成臭氧。再者，在本揭示之冰箱1中，藉由沿面放電而生成臭氧，但亦可藉由例如電暈放電而生成臭氧。所生成之臭氧通過殼體421之開口428，向流通於流路26(圖6)之冷氣放出。The substrate 422 is provided for mounting a power supply circuit (not shown) for high-voltage discharge from the electrode 424. The power supply circuit is controlled by the control device 100 (FIG. 2). Therefore, the control device 100 controls the power supply circuit to control the discharge. The electrode 424 generates ozone by discharging in the air (in the cold air). Ozone is generated between the inductive electrode 426 and the discharge electrode 427 by, for example, performing a surface discharge between the discharge electrode 427 to which a high voltage is applied and the inductive electrode 426 connected to the ground. Furthermore, in the refrigerator 1 of the present disclosure, ozone is generated by surface discharge, but it can also be generated by, for example, coma discharge. The generated ozone is released to the cold air flowing in the flow path 26 (FIG. 6) through the opening 428 of the shell 421.
在圖示之例中，加熱器423對電極424進行加熱。藉此，可局部地加熱電極424附近之空氣之溫度，而可局部地降低相對濕度。而且，藉由可局部地降低相對濕度，可於放電時不易受到水分之影響，從而可增大臭氧之生成量。In the example shown in the figure, the heater 423 heats the electrode 424. In this way, the temperature of the air near the electrode 424 can be locally heated, and the relative humidity can be locally reduced. In addition, by locally reducing the relative humidity, the discharge can be less susceptible to the influence of moisture, thereby increasing the amount of ozone generated.
臭氧生成器42主要生成臭氧。藉此，可充分地利用臭氧之殺菌效果及脫臭效果。此處所言之主要，係指如下情形：除了僅生成臭氧之形態以外，亦允許次要之其他產物之生成，但與其他產物之生成量(例如每單位時間之物質量)相比臭氧之生成量更多。The ozone generator 42 mainly generates ozone. In this way, the sterilization effect and deodorization effect of ozone can be fully utilized. The "mainly" mentioned here refers to the following situation: in addition to the form of ozone, the generation of other secondary products is also allowed, but the amount of ozone generated is greater than the amount of other products generated (for example, the amount of material per unit time).
返回圖2，包含由臭氧生成器42生成之臭氧之冷氣，在形成於背面面板20之背面側之流路26中自臭氧生成器42向上方流動，經由供給口24被供給至冷藏室2(第1儲藏室)。藉由使冷氣如此般流動，而可在冷藏室2之內部空間中自上側供給，可容易使臭氧遍布於冷藏室2之整體。Returning to FIG. 2 , the cold air containing ozone generated by the ozone generator 42 flows upward from the ozone generator 42 in the flow path 26 formed on the back side of the back panel 20, and is supplied to the refrigerating chamber 2 (first storage chamber) through the supply port 24. By making the cold air flow in this way, it can be supplied from the upper side in the inner space of the refrigerating chamber 2, and the ozone can be easily distributed throughout the refrigerating chamber 2.
蔬果保鮮室3係可儲藏蔬菜等之蔬果之室。蔬果保鮮室3固定為冷藏溫度帶。蔬果保鮮室3之溫度較冷藏室2及冷鮮室7即第1儲藏室為高溫，例如作為門3a關閉之狀態之平均溫度，為並不限定於該數值範圍之例如5°C以上7°C以下。亦即 ，可較冷藏室2及冷鮮室7設定成高溫。在本揭示之冰箱1中，藉由冷卻器41產生之冷氣除了施加於冷藏室2及冷鮮室7外亦對蔬果保鮮室3供給，而將蔬果保鮮室3冷卻。The fruit and vegetable fresh-keeping room 3 is a room for storing fruits and vegetables such as vegetables. The fruit and vegetable fresh-keeping room 3 is fixed to a refrigeration temperature zone. The temperature of the fruit and vegetable fresh-keeping room 3 is higher than that of the refrigerator room 2 and the fresh-keeping room 7, i.e., the first storage room. For example, as an average temperature when the door 3a is closed, it is not limited to the numerical range, for example, 5°C or more and 7°C or less. That is, it can be set to a higher temperature than that of the refrigerator room 2 and the fresh-keeping room 7. In the refrigerator 1 of the present disclosure, the cold air generated by the cooler 41 is not only applied to the refrigerator room 2 and the fresh-keeping room 7, but also supplied to the fruit and vegetable fresh-keeping room 3, thereby cooling the fruit and vegetable fresh-keeping room 3.
在蔬果保鮮室3之背面側，設置將冷卻冷藏室2後之冷氣供給至蔬果保鮮室3之供給口31。冰箱1具備供給口31。供給口31連接於流路32(第1流路)。流路32連接於蔬果保鮮室3及返回口28。因此，經由返回口28自冷藏室2排出之冷氣通過流路32，經由供給口31供給至蔬果保鮮室3。On the back side of the fruit and vegetable fresh-keeping chamber 3, a supply port 31 is provided to supply the cold air after cooling the refrigerator chamber 2 to the fruit and vegetable fresh-keeping chamber 3. The refrigerator 1 has the supply port 31. The supply port 31 is connected to the flow path 32 (first flow path). The flow path 32 is connected to the fruit and vegetable fresh-keeping chamber 3 and the return port 28. Therefore, the cold air discharged from the refrigerator chamber 2 through the return port 28 passes through the flow path 32 and is supplied to the fruit and vegetable fresh-keeping chamber 3 through the supply port 31.
在蔬果保鮮室3之背面側，設置將冷卻蔬果保鮮室3之冷氣返回冷卻器41之返回口34(蔬果保鮮室返回口)。冰箱1具備返回口34。返回口34與收容有冷卻器41之室44連通。因此，藉由冷卻器41產生之冷氣施加於冷藏室2及冷鮮室7且亦對蔬果保鮮室3供給。而且，在亦對蔬果保鮮室3供給時，冷卻蔬果保鮮室3之冷氣經由返回口34自蔬果保鮮室3排出，且返回冷卻器41。藉此，可藉由冷卻器41將使用於蔬果保鮮室3之冷卻而成為高濕之冷氣除濕，而可抑制在其他儲藏室之非意圖之結露。On the back side of the fruit and vegetable fresh-keeping chamber 3, a return port 34 (fruit and vegetable fresh-keeping chamber return port) is provided for returning the cold air that has cooled the fruit and vegetable fresh-keeping chamber 3 to the cooler 41. The refrigerator 1 is provided with the return port 34. The return port 34 is connected to a chamber 44 that houses the cooler 41. Therefore, the cold air generated by the cooler 41 is applied to the refrigerating chamber 2 and the cold-keeping chamber 7 and is also supplied to the fruit and vegetable fresh-keeping chamber 3. Moreover, when the fruit and vegetable fresh-keeping chamber 3 is also supplied, the cold air that has cooled the fruit and vegetable fresh-keeping chamber 3 is discharged from the fruit and vegetable fresh-keeping chamber 3 through the return port 34 and returns to the cooler 41. In this way, the cold air that has become high humidity due to cooling the fruit and vegetable fresh-keeping chamber 3 can be dehumidified by the cooler 41, and unintentional condensation in other storage chambers can be suppressed.
在臭氧生成器42之下方，配置有返回口25、28、或返回口34之至少一者。在圖示之例中，返回口34配置於臭氧生成器42之下方。藉此，在風扇43停止時，可將包含臭氧生成器42之附近之流路26之冷氣，經由返回口34流入蔬果保鮮室3。其結果為，可將由臭氧生成器42生成之臭氧毫無浪費地使用於殺菌及脫臭。較佳的是，在蔬果保鮮室3之門之閉塞時，容器33位於返回口34之正下方，以便將臭氧有效果地供給至容器33(後述)內。At least one of the return ports 25, 28, or the return port 34 is disposed below the ozone generator 42. In the illustrated example, the return port 34 is disposed below the ozone generator 42. Thus, when the fan 43 stops, the cold air of the flow path 26 near the ozone generator 42 can flow into the fruit and vegetable fresh-keeping chamber 3 through the return port 34. As a result, the ozone generated by the ozone generator 42 can be used for sterilization and deodorization without waste. Preferably, when the door of the fruit and vegetable fresh-keeping chamber 3 is closed, the container 33 is located directly below the return port 34 so that ozone can be effectively supplied to the container 33 (described later).
在蔬果保鮮室3配置有收容蔬果之容器33。容器33之上方開口，以覆蓋該開口之方式配置有蓋(未圖示)。若使用者將門3a向正面側拉出，則容器33與門3a成為一體地向正面側被拉出。此時，蓋未自蔬果保鮮室3拉出，而遺留於蔬果保鮮室3之內部。另一方面，若使用者推進門3a，則容器33與門3a成為一體地推入至蔬果保鮮室3，而容器33之上部開口被蓋閉塞。蓋為氣體可通過容器33之上部開口之程度之氣密性。藉此，臭氧可供給至容器33。又，本實施形態之蔬果保鮮室3因供給來自冷藏室2之高濕冷氣，故不一定需要蓋。因此，供給口31可設為向蔬果保鮮室3之容器33內噴出冷氣之所謂直接冷卻方式。A container 33 for storing fruits and vegetables is arranged in the fruit and vegetable preservation chamber 3. The upper part of the container 33 is opened, and a lid (not shown) is arranged in a manner to cover the opening. If the user pulls the door 3a to the front side, the container 33 and the door 3a are pulled out to the front side as a whole. At this time, the lid is not pulled out from the fruit and vegetable preservation chamber 3, but remains inside the fruit and vegetable preservation chamber 3. On the other hand, if the user pushes the door 3a, the container 33 and the door 3a are pushed into the fruit and vegetable preservation chamber 3 as a whole, and the upper opening of the container 33 is closed by the lid. The lid is airtight to the extent that gas can pass through the upper opening of the container 33. In this way, ozone can be supplied to the container 33. In addition, since the fruit and vegetable preservation chamber 3 of the present embodiment is supplied with high-humidity cold air from the refrigerator chamber 2, it is not necessarily necessary to have a lid. Therefore, the supply port 31 can be configured to spray cold air into the container 33 of the fruit and vegetable preservation chamber 3, which is a so-called direct cooling method.
在本揭示之冰箱1中，藉由冷卻器41產生之冷氣在經由供給口24供給至冷藏室2(第1儲藏室)之後，自冷藏室2排出且供給至蔬果保鮮室3。因此，在冷藏室2中冷卻後稍許升溫、且包含臭氧之冷氣，通過流路32被供給至蔬果保鮮室3。藉此，可抑制較冷藏室2為高溫之蔬果保鮮室3之過冷。又，因在蔬果保鮮室3例如充滿臭氧，故蔬果之表面被臭氧殺菌。藉此，可長期間地維持蔬果之鮮度。又，亦可將蔬果保鮮室3之內部脫臭。進而，藉由配置於容器33之上方之蓋而抑制包含臭氧之冷氣向容器33之內部之流入。藉此，可抑制因冷氣向蔬果之接觸所致之蔬果之乾燥。In the refrigerator 1 of the present disclosure, the cold air generated by the cooler 41 is supplied to the refrigerator chamber 2 (first storage chamber) through the supply port 24, and then discharged from the refrigerator chamber 2 and supplied to the fruit and vegetable preservation chamber 3. Therefore, the cold air containing ozone, which is slightly heated after being cooled in the refrigerator chamber 2, is supplied to the fruit and vegetable preservation chamber 3 through the flow path 32. In this way, the overcooling of the fruit and vegetable preservation chamber 3, which is higher in temperature than the refrigerator chamber 2, can be suppressed. In addition, since the fruit and vegetable preservation chamber 3 is filled with ozone, the surface of the fruit and vegetable is sterilized by the ozone. In this way, the freshness of the fruit and vegetable can be maintained for a long time. In addition, the interior of the fruit and vegetable preservation chamber 3 can also be deodorized. Furthermore, the inflow of the cold air containing ozone into the interior of the container 33 is suppressed by a cover arranged above the container 33. In this way, the drying of fruits and vegetables caused by the contact of cold air with the fruits and vegetables can be suppressed.
圖8係顯示風扇43及臭氧生成器42之動作時序之時序圖。控制裝置100(圖2)進行如下之控制：在使風扇43驅動而使包含臭氧之冷氣在冷藏室2與冷卻器41之間循環特定時間後，使風扇43停止且待機特定時間。藉由如此之控制，可藉由冷氣之循環而在冷藏室2充滿臭氧，同時藉由在充滿之狀態下待機，而使冷藏室2內部之冷氣及臭氧擴散地供給至冷鮮室7(圖2)之內部。其結果為，可對儲藏於冷鮮室7之食品進行殺菌。又，可對冷鮮室7之內部進行脫臭。FIG8 is a timing chart showing the operation timing of the fan 43 and the ozone generator 42. The control device 100 (FIG2) performs the following control: after the fan 43 is driven to circulate the cold air containing ozone between the refrigerator 2 and the cooler 41 for a specific time, the fan 43 is stopped and waited for a specific time. By such control, the refrigerator 2 can be filled with ozone by the circulation of the cold air, and at the same time, by waiting in a filled state, the cold air and ozone inside the refrigerator 2 can be diffusely supplied to the inside of the fresh room 7 (FIG2). As a result, the food stored in the fresh room 7 can be sterilized. In addition, the inside of the fresh room 7 can be deodorized.
控制裝置100在風扇43之驅動中利用臭氧生成器42生成臭氧，且在風扇43之停止中利用臭氧生成器42停止臭氧之生成。藉由如此般設置，可抑制不使用於殺菌及脫臭之臭氧之生成量，而可有效率地生成臭氧。The control device 100 generates ozone using the ozone generator 42 when the fan 43 is driven, and stops the generation of ozone using the ozone generator 42 when the fan 43 is stopped. By setting in this way, the generation amount of ozone not used for sterilization and deodorization can be suppressed, and ozone can be generated efficiently.
在本揭示之冰箱1中，在時刻t0而門2a、2b打開時，控制裝置100停止風扇43及臭氧生成器42。在時刻t1而由使用者關閉門2a、2b時，控制裝置100使風扇43及臭氧生成器42驅動。藉此，包含臭氧之冷氣至少在冷藏室2之內外循環。藉此，在冷藏室2充滿臭氧。在到達經過特定時間後之時刻t2時，控制裝置100使風扇43及臭氧生成器42停止。然後，控制裝置100持續停止風扇43及臭氧生成器42直至時刻t3。因此，在時刻t2至時刻t3，執行臭氧向冷鮮室7之擴散。In the refrigerator 1 of the present disclosure, at time t0 when the doors 2a and 2b are opened, the control device 100 stops the fan 43 and the ozone generator 42. At time t1 when the user closes the doors 2a and 2b, the control device 100 drives the fan 43 and the ozone generator 42. Thereby, the cold air containing ozone circulates at least inside and outside the refrigerating chamber 2. Thereby, the refrigerating chamber 2 is filled with ozone. At time t2 after a specific time has passed, the control device 100 stops the fan 43 and the ozone generator 42. Then, the control device 100 continues to stop the fan 43 and the ozone generator 42 until time t3. Therefore, from time t2 to time t3, the diffusion of ozone to the fresh-keeping chamber 7 is performed.
使冷氣以何一程度之時間循環(即時刻t1至t2之特定時間)、及為了擴散而待機何一程度之時間 (亦即時刻t2至t3之特定時間)，根據冰箱1之構造(例如冷藏室2之容積、冷鮮室7之構造)等而不同。因此，該等時間例如可藉由模擬、實驗等而決定。The time for circulating the cold air (i.e., the specific time from time t1 to t2) and the time for waiting for diffusion (i.e., the specific time from time t2 to t3) vary according to the structure of the refrigerator 1 (e.g., the volume of the refrigerating chamber 2, the structure of the fresh-keeping chamber 7), etc. Therefore, these times can be determined by simulation, experiment, etc.
圖9係控制裝置100之方塊圖。控制裝置100除了上述控制以外，亦控制冰箱1之運轉(例如構成冷凍循環(未圖示)之壓縮機101之運轉等)。控制裝置100例如構成為包含CPU(Central Processing Unit，中央處理單元)1001、RAM(Random Access Memory，隨機存取記憶體)1002、ROM(Read Only Memory，唯讀記憶體)1003等。控制裝置100之儲存於ROM 1003之特定之控制程式(例如冷藏方法)藉由在RAM 1002展開，且利用CPU 1001執行而具體化。FIG9 is a block diagram of the control device 100. In addition to the above-mentioned control, the control device 100 also controls the operation of the refrigerator 1 (for example, the operation of the compressor 101 constituting the refrigeration cycle (not shown)). The control device 100 is configured to include, for example, a CPU (Central Processing Unit) 1001, a RAM (Random Access Memory) 1002, and a ROM (Read Only Memory) 1003. The specific control program (for example, the refrigeration method) stored in the ROM 1003 of the control device 100 is expanded in the RAM 1002 and executed by the CPU 1001 to be embodied.
返回圖2，製冰室(未圖示)、第1冷凍室5及第2冷凍室6分別係可儲藏製成之冰、及冷凍食品等冷凍物、且固定為冷凍溫度帶之儲藏室(第2儲藏室)。製冰室、第1冷凍室5及第2冷凍室6之溫度分別作為例如門3a、4a、5a、6a關閉之狀態之平均溫度，為並不限定於該數值範圍之例如-20°C以上-10°C以下。Returning to FIG. 2 , the ice making room (not shown), the first freezing room 5 and the second freezing room 6 are storage rooms (second storage rooms) fixed to a freezing temperature zone for storing made ice and frozen foods. The temperatures of the ice making room, the first freezing room 5 and the second freezing room 6 are not limited to the numerical range, for example, above -20°C and below -10°C, as average temperatures when the doors 3a, 4a, 5a and 6a are closed.
在冰箱1中，藉由冷卻器41產生之冷氣不供給至製冰室、第1冷凍室5及第2冷凍室6等之冷凍溫度帶之第2儲藏室。因此，冰箱1具備用於冷卻製冰室、第1冷凍室5及第2冷凍室6之冷卻器51。藉由風扇52之驅動而由冷卻器51產生之冷氣，經由配置於製冰室、第1冷凍室5及第2冷凍室6之背面側之供給口53供給至製冰室、第1冷凍室5及第2冷凍室6。冷卻製冰室、第1冷凍室5及第2冷凍室6之冷氣，經由返回口54返回收容冷卻器51之室55。In the refrigerator 1, the cold air generated by the cooler 41 is not supplied to the second storage room of the freezing temperature zone such as the ice-making room, the first freezing room 5 and the second freezing room 6. Therefore, the refrigerator 1 is provided with a cooler 51 for cooling the ice-making room, the first freezing room 5 and the second freezing room 6. The cold air generated by the cooler 51 driven by the fan 52 is supplied to the ice-making room, the first freezing room 5 and the second freezing room 6 through the supply port 53 arranged on the back side of the ice-making room, the first freezing room 5 and the second freezing room 6. The cold air cooling the ice-making room, the first freezing room 5 and the second freezing room 6 returns to the room 55 accommodating the cooler 51 through the return port 54.
圖10係又一實施形態之冰箱1之剖視圖。在圖10所示之實施形態中，返回口28連接於流路32(第1流路)、及連接於收容冷卻器41之室44之流路45(第2流路)。在流路32或流路45之至少一者，設置控制機構46，其控制使冷卻冷藏室2之冷氣向流路32與流路45之任一者流動。藉由如此般設置，而可使用控制機構46控制將冷卻冷藏室2之冷氣供給至蔬果保鮮室3、抑或返回冷卻器41。FIG. 10 is a cross-sectional view of a refrigerator 1 according to another embodiment. In the embodiment shown in FIG. 10 , the return port 28 is connected to the flow path 32 (first flow path) and the flow path 45 (second flow path) connected to the chamber 44 containing the cooler 41. A control mechanism 46 is provided in at least one of the flow path 32 and the flow path 45, and controls the cold air of the refrigerating chamber 2 to flow to either the flow path 32 or the flow path 45. By providing in this way, the control mechanism 46 can be used to control whether the cold air of the refrigerating chamber 2 is supplied to the fruit and vegetable fresh-keeping chamber 3 or returned to the cooler 41.
控制機構46在圖示之例中係將流路32之蔬果保鮮室3側之開口端即供給口31閉塞之風閥，但控制機構46並不限定於風閥。又，控制機構46可設在流路32之中途，可設在流路45之開口端，亦可設在流路45之中途。控制機構46例如可由控制裝置100控制。例如，在蔬果保鮮室3升溫等之情形下對蔬果保鮮室3進行冷卻時，控制裝置100將控制機構46即風閥設為全開。另一方面，在蔬果保鮮室3之溫度過於下降等之情形下不對蔬果保鮮室3進行冷卻時，控制裝置100將控制機構46即風閥設為全閉。In the illustrated example, the control mechanism 46 is a damper that closes the open end of the flow path 32 on the fruit and vegetable preservation chamber 3 side, i.e., the supply port 31, but the control mechanism 46 is not limited to the damper. In addition, the control mechanism 46 can be arranged in the middle of the flow path 32, at the open end of the flow path 45, or in the middle of the flow path 45. The control mechanism 46 can be controlled by the control device 100, for example. For example, when the fruit and vegetable preservation chamber 3 is cooled when the temperature of the fruit and vegetable preservation chamber 3 rises, the control device 100 sets the control mechanism 46, i.e., the damper, to be fully opened. On the other hand, when the fruit and vegetable preservation chamber 3 is not cooled when the temperature of the fruit and vegetable preservation chamber 3 drops too much, the control device 100 sets the control mechanism 46, i.e., the damper, to be fully closed.
在圖10所示之冰箱1中，可自冷藏室2之內部適當省略冷鮮室7。該情形下，可將冷藏室2設定成冷鮮溫度帶(-3°C以上4°C以下。更佳為-3°C以上2°C以下)。冷藏室2可設為除了冷鮮溫度帶以外，亦可選擇較其為高溫且較蔬果保鮮室3之設定溫度為低溫作為設定溫度。此時，冷藏室2之設定溫度可選擇至少2種。因此，該情形下，第1儲藏室係可切換成包含冷鮮溫度帶之複數個冷藏溫度帶的冷藏室2。In the refrigerator 1 shown in FIG. 10 , the fresh-keeping compartment 7 can be appropriately omitted from the interior of the refrigerating compartment 2. In this case, the refrigerating compartment 2 can be set to a fresh-keeping temperature zone (above -3°C and below 4°C. More preferably, above -3°C and below 2°C). In addition to the fresh-keeping temperature zone, the refrigerating compartment 2 can also be set to a temperature that is higher than the fresh-keeping temperature zone and lower than the setting temperature of the fruit and vegetable preservation compartment 3. At this time, at least two setting temperatures of the refrigerating compartment 2 can be selected. Therefore, in this case, the first storage compartment can be switched to a refrigerating compartment 2 having multiple refrigeration temperature zones including the fresh-keeping temperature zone.
如此般，在本揭示之冰箱1中，因冷藏室2之設定溫度可設為溫度比通常為低之冷鮮溫度帶，故與蔬果保鮮室3之設定溫度差變大。又，因亦向蔬果保鮮室3供給冷氣，故容易凸顯出蔬果保鮮室3之過度冷卻之虞。因此，藉由如上述般配置控制機構46，而可抑制冷卻冷藏室2之影響超出必要地波及至蔬果保鮮室3而使得蔬果保鮮室3變得過度低溫。As such, in the refrigerator 1 of the present disclosure, since the set temperature of the refrigerating chamber 2 can be set to a cold and fresh temperature zone lower than usual, the difference between the set temperature of the fruit and vegetable preservation chamber 3 becomes larger. In addition, since cold air is also supplied to the fruit and vegetable preservation chamber 3, the risk of overcooling of the fruit and vegetable preservation chamber 3 is easily highlighted. Therefore, by configuring the control mechanism 46 as described above, it is possible to prevent the influence of cooling the refrigerating chamber 2 from exceedingly affecting the fruit and vegetable preservation chamber 3 and causing the fruit and vegetable preservation chamber 3 to become excessively low in temperature.
流路32及流路45構成為流路32之風量小於流路45之風量。因此，由冷卻器41產生之冷氣在亦對蔬果保鮮室3供給時，以較冷藏室2為少量之方式供給至蔬果保鮮室3。藉由如此般設置，可使供給至蔬果保鮮室3之冷氣少於返回冷卻器41之冷氣，而可抑制蔬果保鮮室3過冷。在流路32及流路45各者中，風量控制例如可藉由改變流路剖面積而執行。例如，藉由使流路32中最窄之流路部分之流路剖面積較流路45中最窄之流路部分之流路剖面積更窄，而可使流路32之風量小於流路45之風量。The flow path 32 and the flow path 45 are configured such that the air volume of the flow path 32 is smaller than the air volume of the flow path 45. Therefore, when the cold air generated by the cooler 41 is also supplied to the fruit and vegetable preservation chamber 3, it is supplied to the fruit and vegetable preservation chamber 3 in a smaller amount than the refrigerating chamber 2. By setting it in this way, the cold air supplied to the fruit and vegetable preservation chamber 3 can be less than the cold air returned to the cooler 41, and the fruit and vegetable preservation chamber 3 can be suppressed from being overcooled. In each of the flow path 32 and the flow path 45, the air volume control can be performed by changing the flow path cross-sectional area, for example. For example, by making the flow path cross-sectional area of the narrowest flow path portion in the flow path 32 narrower than the flow path cross-sectional area of the narrowest flow path portion in the flow path 45, the air volume of the flow path 32 can be made smaller than the air volume of the flow path 45.
圖11係再一實施形態之冰箱1之剖視圖。在圖11所示之實施形態中，藉由冷卻器41產生之冷氣不冷卻蔬果保鮮室3。因此，在圖11所示之冰箱1中，藉由冷卻器41產生之冷氣僅將冷藏室2及冷鮮室7作為冷卻對象。因此，冷卻冷藏室2後之冷氣經由連接於收容冷卻器41之室44之返回口28，直接返回冷卻器41。FIG. 11 is a cross-sectional view of a refrigerator 1 in another embodiment. In the embodiment shown in FIG. 11 , the cold air generated by the cooler 41 does not cool the fruit and vegetable fresh-keeping chamber 3. Therefore, in the refrigerator 1 shown in FIG. 11 , the cold air generated by the cooler 41 only cools the refrigerating chamber 2 and the fresh-keeping chamber 7. Therefore, the cold air after cooling the refrigerating chamber 2 directly returns to the cooler 41 via the return port 28 of the chamber 44 connected to the accommodating cooler 41.
蔬果保鮮室3藉由冷卻器51所產生之冷氣而被冷卻。收容冷卻器51之室55與蔬果保鮮室3經由供給口56及返回口57而連通。供給口56及返回口57形成於蔬果保鮮室3之例如背面側，但該等之形成位置並不限定於背面側及圖示之位置。藉由未圖示之風扇驅動，經由供給口56將室55之冷氣供給至蔬果保鮮室3。藉此，冷卻蔬果保鮮室3。冷卻蔬果保鮮室3後之冷氣經由返回口57返回室55。The fruit and vegetable fresh-keeping chamber 3 is cooled by the cold air generated by the cooler 51. The chamber 55 that accommodates the cooler 51 is connected to the fruit and vegetable fresh-keeping chamber 3 through the supply port 56 and the return port 57. The supply port 56 and the return port 57 are formed on the back side of the fruit and vegetable fresh-keeping chamber 3, for example, but the formation positions are not limited to the back side and the positions shown in the figure. The cold air in the chamber 55 is supplied to the fruit and vegetable fresh-keeping chamber 3 through the supply port 56 by driving a fan (not shown). In this way, the fruit and vegetable fresh-keeping chamber 3 is cooled. The cold air after cooling the fruit and vegetable fresh-keeping chamber 3 returns to the chamber 55 through the return port 57.
在上述各實施形態中，冰箱1具備製冰室、第1冷凍室5及第2冷凍室6等之第2儲藏室。然而，亦可不具備第2儲藏室。在不具備第2儲藏室之冰箱1中，藉由冷卻器41產生之冷氣，不冷卻第2儲藏室。又，在上述各實施形態中，冰箱1具備蔬果保鮮室3。然而，可不具備蔬果保鮮室3。在不具備蔬果保鮮室3之冰箱1中，藉由冷卻器41產生之冷氣不冷卻蔬果保鮮室3。In each of the above-mentioned embodiments, the refrigerator 1 has a second storage room including an ice-making room, a first freezing room 5, and a second freezing room 6. However, the second storage room may not be provided. In the refrigerator 1 not having the second storage room, the cold air generated by the cooler 41 does not cool the second storage room. In addition, in each of the above-mentioned embodiments, the refrigerator 1 has a fruit and vegetable fresh-keeping room 3. However, the fruit and vegetable fresh-keeping room 3 may not be provided. In the refrigerator 1 not having the fruit and vegetable fresh-keeping room 3, the cold air generated by the cooler 41 does not cool the fruit and vegetable fresh-keeping room 3.
