Description

空調機air conditioner

本發明有關空調機。The present invention relates to an air conditioner.

一般，在內部具備送風風扇的空調機使用時間越長，塵埃在送風風扇附著得越多。由此，空調機有風量減低、耗電增加的情事。另外，空調機有時由於塵埃的附著而產生黴等，存在不衛生的情況。因此，提供有一種空調機，其具備去除附著於送風風扇的塵埃清掃送風風扇的風扇清掃裝置(例如，參閱專利文獻1)。專利文獻1記載的空調機具備風扇清掃裝置和控制風扇清掃裝置的控制裝置，且具有向室內吹出調節空氣的通常運轉模式、和使風扇低速旋轉並且使風扇清掃裝置可動的風扇清掃運轉模式。風扇清掃裝置構成為，包含風扇清掃運轉模式時抵接於風扇的清掃部，且通常運轉模式下可移動至使清掃部避開風扇的位置。 [先前技術文獻] [專利文獻]Generally, the longer the use time of an air conditioner equipped with a blower fan is, the more dust will adhere to the blower fan. As a result, the air conditioner may have reduced air volume and increased power consumption. In addition, the air conditioner may produce mold or the like due to adhesion of dust, which may be unsanitary. Therefore, there is provided an air conditioner provided with a fan cleaning device that cleans the blower fan by removing dust attached to the blower fan (for example, refer to Patent Document 1). The air conditioner described in Patent Document 1 includes a fan cleaning device and a control device that controls the fan cleaning device, and has a normal operation mode in which conditioned air is blown into the room, and a fan cleaning operation mode in which the fan is rotated at a low speed and the fan cleaning device is movable. The fan cleaning device is configured to include a cleaning part that abuts against the fan in the fan cleaning operation mode, and is movable to a position where the cleaning part avoids the fan in the normal operation mode.

專利文獻1：日本特許第4046755號公報Patent Document 1: Japanese Patent No. 4046755

[本發明所欲解決之課題][Problem to be solved by the present invention]

專利文獻1雖然記載了用風扇清掃裝置的清掃部除去附著於送風風扇的塵埃，但是關於清掃部的更換並未記載。另一方面，風扇清掃裝置具備抵接於送風風扇的刷子等清掃部。就該清掃部而言，累計清掃時間越長，越劣化、越磨損，因此存在清掃效果降低的可能性。因此，希望使空調機的風扇清掃裝置的清掃部的更換容易化。Although Patent Document 1 describes that the cleaning part of the fan cleaning device removes dust adhering to the blower fan, it does not describe the replacement of the cleaning part. On the other hand, the fan cleaning device is equipped with cleaning parts, such as a brush which contact|abuts to a blower fan. With regard to this cleaning part, the longer the accumulated cleaning time, the more deteriorated and worn, and therefore there is a possibility that the cleaning effect will decrease. Therefore, it is desired to facilitate the replacement of the cleaning part of the fan cleaning device of the air conditioner.

本發明是為了解決前述的課題而為之創作，主要目的在於提供可以容易地進行清掃部的更換的空調機。 [用以解決課題之手段]The present invention was created to solve the aforementioned problems, and its main object is to provide an air conditioner that can easily replace the cleaning part. [Means to solve the problem]

為了實現前述目的，本發明為空調機，其構成為，具備熱交換器、送風風扇、以及清掃前述送風風扇的風扇清掃裝置，前述風扇清掃裝置具有軸桿、將前述軸桿繞軸旋轉方向旋轉驅動的馬達、以及安裝於前述軸桿的清掃部，前述清掃部和前述軸桿為分體。 對於其它方案，後述之。 [發明效果]In order to achieve the foregoing object, the present invention is an air conditioner, which is configured to include a heat exchanger, a blower fan, and a fan cleaning device for cleaning the blower fan. The fan cleaning device has a shaft and rotates the shaft around the axis. The driving motor and the cleaning part attached to the shaft, and the cleaning part and the shaft are separate bodies. For other solutions, I will describe them later. [Effects of the invention]

根據本發明，可以容易地進行風扇清掃裝置的清掃部更換。According to the present invention, the cleaning part of the fan cleaning device can be easily replaced.

以下，參閱附圖，對本發明的實施方式(以下，稱為「本實施方式」)詳細地進行說明。此外，各圖指示在可以充分理解本發明的程度上概略地示出。因此，本發明不被僅限定於圖示例。另外，各圖中，對共通的構成要素、相同的構成要素標注相同的符號，省略它們的重複的說明。Hereinafter, referring to the drawings, an embodiment of the present invention (hereinafter referred to as "this embodiment") will be described in detail. In addition, each figure indicates a schematic diagram to the extent that the present invention can be fully understood. Therefore, the present invention is not limited only to the illustrated example. In addition, in each figure, common components and the same components are denoted by the same reference numerals, and their overlapping descriptions are omitted.

[實施方式1] 本實施方式1意圖提供一種空調機10，以可以僅進行清掃部的更換的方式，從而抑制使用成本。另外，本實施方式1還意圖提供一種空調機10，在將來研發出被賦予特殊的附加功能的清掃部等的情況下，可以容易地更換為該清掃部等。[Embodiment 1] This Embodiment 1 intends to provide an air conditioner 10 in a manner that only the cleaning part can be replaced, thereby suppressing the use cost. In addition, this Embodiment 1 also intends to provide an air conditioner 10, which can be easily replaced with the cleaning unit or the like when a cleaning unit or the like to which a special additional function is provided in the future is developed.

＜空調機的整體結構＞ 以下，參閱圖1，對本實施方式1的空調機10的整體結構進行說明。圖1是表示本實施方式1的空調機10的整體結構的概略圖。＜The overall structure of the air conditioner＞ Hereinafter, referring to Fig. 1, the overall configuration of the air conditioner 10 of the first embodiment will be described. Fig. 1 is a schematic diagram showing the overall configuration of an air conditioner 10 according to the first embodiment.

如圖1所示，空調機10具有配置於室內的室內機11、和配置於室外的室外機12。As shown in Fig. 1, the air conditioner 10 has an indoor unit 11 arranged indoors and an outdoor unit 12 arranged outdoors.

室內機11將室內空氣吸入內部，使吸入的室內空氣通過熱交換器31(參閱圖2)，得到被實施了加熱、冷卻、以及除濕的某任意的處理的調節空氣，通過將得到的調節空氣向室內吹出，從而對室內進行空氣調節。室內機11經由連接配管13與室外機12連接，在與室外機12之間使冷媒循環。室外機12在與循環的冷媒之間進行熱交換。The indoor unit 11 sucks indoor air into the interior, passes the sucked indoor air through the heat exchanger 31 (see FIG. 2), and obtains conditioned air that has been subjected to any arbitrary processing of heating, cooling, and dehumidification. Blow into the room to air-condition the room. The indoor unit 11 is connected to the outdoor unit 12 via a connecting pipe 13 and circulates a refrigerant between the outdoor unit 12 and the outdoor unit 12. The outdoor unit 12 exchanges heat with the circulating refrigerant.

室內機11利用框體21和作為其外裝構件的裝飾框22將送風風扇38(參閱圖2)、熱交換器31(參閱圖2)等構造體包含於內部。送風風扇38是從空氣吸入口24側向空氣吹出口25側輸送空氣的貫流風扇，輸送通過熱交換器31進行了熱交換的空氣。熱交換器31是在與冷媒之間進行熱交換的單元。The indoor unit 11 includes structural bodies such as a blower fan 38 (refer to FIG. 2) and a heat exchanger 31 (refer to FIG. 2) using a frame body 21 and a decorative frame 22 as its exterior member. The blower fan 38 is a cross-flow fan that sends air from the air suction port 24 side to the air blowout port 25 side, and sends air that has been heat-exchanged by the heat exchanger 31. The heat exchanger 31 is a unit that exchanges heat with the refrigerant.

在圖1所示的例子中，在裝飾框22(外裝構件)的前部面的上側部分安裝有前部面面板23。前部面面板23是覆蓋室內機11的前部面的構件。另外，在裝飾框22的前部面的下側部分安裝有上下風向板26。In the example shown in FIG. 1, the front surface panel 23 is attached to the upper part of the front surface of the decorative frame 22 (exterior member). The front face panel 23 is a member that covers the front face of the indoor unit 11. In addition, a vertical wind direction plate 26 is attached to the lower part of the front surface of the decorative frame 22.

上下風向板26是限定從空氣吹出口25吐出的調節空氣的上下方向的朝向的構件。上下風向板26構成為，以上側部分在上下方向上開閉的方式在下端附近軸支撐於裝飾框22(或框體21)，並且藉由未圖示的驅動部而旋轉。室內機11經由打開上下風向板26而形成空氣吹出口25。The vertical wind direction plate 26 is a member that restricts the vertical direction of the conditioned air discharged from the air blowing port 25. The up-and-down wind direction plate 26 is configured to be pivotally supported by the decorative frame 22 (or the frame body 21) near the lower end such that the upper side portion opens and closes in the up-down direction, and is rotated by a driving unit not shown. The indoor unit 11 forms an air blowing port 25 by opening the up and down wind direction plate 26.

＜送風風扇附近的結構＞ 以下，參閱圖2，對空調機10的室內機11的送風風扇38附近的結構進行說明。圖2是表示送風風扇38附近的結構的概略圖。＜Structure around the blower fan＞ Hereinafter, referring to FIG. 2, the structure in the vicinity of the blower fan 38 of the indoor unit 11 of the air conditioner 10 will be described. FIG. 2 is a schematic diagram showing the structure in the vicinity of the blower fan 38.

如圖2所示，在室內機11的內部配置有前述的送風風扇38、前述的熱交換器31等構造體。室內機11若連續使用，則塵埃等附著於送風風扇38。因此，室內機11具有用於清掃送風風扇38的風扇清掃裝置40。As shown in FIG. 2, structures such as the aforementioned blower fan 38 and the aforementioned heat exchanger 31 are arranged inside the indoor unit 11. If the indoor unit 11 is used continuously, dust and the like will adhere to the blower fan 38. Therefore, the indoor unit 11 has a fan cleaning device 40 for cleaning the blower fan 38.

＜風扇清掃裝置的結構＞ 以下，參閱圖3及圖4，對風扇清掃裝置40的刷子41(清掃部)的結構進行說明。圖3及圖4分別是表示刷子41的結構的立體圖。圖3示出了刷子41為滑動的構造。圖4示出了刷子41為可彎曲的構造。＜Structure of fan cleaning device＞ Hereinafter, referring to FIGS. 3 and 4, the structure of the brush 41 (cleaning part) of the fan cleaning device 40 will be described. 3 and 4 are perspective views showing the structure of the brush 41, respectively. Fig. 3 shows a configuration in which the brush 41 is sliding. FIG. 4 shows that the brush 41 has a bendable configuration.

如圖3所示，在本實施方式中，風扇清掃裝置40具有刷子41、保持部44、軸桿45、以及馬達34(參閱圖2)。刷子41的刷底座43和保持部44的一方具有可在送風風扇38的縱長方向上滑動地收容另一方的槽狀的收容部。在此，設為保持部44具有槽狀的收容部44a而進行說明。另外，保持部44和軸桿45的一方具有可在送風風扇38的縱長方向上滑動地收容另一方的槽狀的收容部。在此，設為軸桿45具有槽狀的收容部45a來進行說明。As shown in FIG. 3, in this embodiment, the fan cleaning device 40 has the brush 41, the holding part 44, the shaft 45, and the motor 34 (refer FIG. 2). One of the brush base 43 and the holding portion 44 of the brush 41 has a groove-shaped accommodating portion slidably accommodating the other in the longitudinal direction of the blower fan 38. Here, the description will be made assuming that the holding portion 44 has a groove-shaped accommodating portion 44a. In addition, one of the holding portion 44 and the shaft 45 has a groove-shaped accommodating portion slidably accommodating the other in the longitudinal direction of the blower fan 38. Here, the description will be made assuming that the shaft 45 has a groove-shaped accommodating portion 45a.

刷子41是抵接於送風風扇38來清掃的構件(清掃部)。 保持部44是保持刷子41的構件。 軸桿45是將保持部44與刷子41(清掃部)一起保持的構件。 馬達34是將軸桿45在繞軸旋轉方向上旋轉驅動的驅動機構。The brush 41 is a member (cleaning part) which comes into contact with the blower fan 38 and cleans. The holding portion 44 is a member that holds the brush 41. The shaft 45 is a member that holds the holding part 44 together with the brush 41 (cleaning part). The motor 34 is a drive mechanism that rotationally drives the shaft 45 in the direction of rotation around the shaft.

此外，刷子41和軸桿45為分體。刷子41在送風風扇38的縱長方向上自如移動規定距離地安裝於軸桿45。刷子41直接或透過其它構件(在此，後述的保持部44)安裝於軸桿45。在此，設為刷子41透過作為其它構件的保持部44安裝於軸桿45來說明。刷子41安裝於保持部44，由此可以確保可彎曲的適度的彈性，並且得到適於向軸桿45安裝的剛性。因此，刷子41可以實現相對於軸桿45的安裝的容易化。但是，風扇清掃裝置40可以設為刪除保持部44的結構。該結構的情況下，刷子41直接相對於軸桿45進行安裝及拆卸。此外，「彈性」是指若從外部對物體施加力，則發生變形，若去除該力，則欲返回原始形狀的性質。另外，「剛性」是指，在對物體施加外力而欲使之變形時，物體抵擋該變形的性質。In addition, the brush 41 and the shaft 45 are separate bodies. The brush 41 is attached to the shaft 45 so as to freely move a predetermined distance in the longitudinal direction of the blower fan 38. The brush 41 is attached to the shaft 45 directly or through another member (here, a holding portion 44 described later). Here, it is assumed that the brush 41 is attached to the shaft 45 through the holding portion 44 as another member. The brush 41 is attached to the holding portion 44, thereby ensuring moderate flexibility for bending and obtaining rigidity suitable for attachment to the shaft 45. Therefore, the brush 41 can be easily attached to the shaft 45. However, the fan cleaning device 40 may be configured to delete the holding portion 44. In the case of this structure, the brush 41 is directly attached to and detached from the shaft 45. In addition, "elasticity" refers to the property that if a force is applied to an object from the outside, it will deform, and if the force is removed, it will return to its original shape. In addition, "rigidity" refers to the property of the object to resist the deformation when an external force is applied to the object to make it deform.

刷子41、保持部44以及軸桿45分別為長條的構件。以下，將刷子41、保持部44以及軸桿45總稱為「刷子41等」。刷子41等可繞軸旋轉地配置於熱交換器31的鰭片32與送風風扇38之間。刷子41等比送風風扇38的縱長方向長度稍長，以覆蓋送風風扇38的縱長方向的整個區域。刷子41等以兩端部貫通配置於熱交換器31的兩端部的2個側板33(參閱圖12)的方式配置。The brush 41, the holding portion 44, and the shaft 45 are long members. Hereinafter, the brush 41, the holding portion 44, and the shaft 45 are collectively referred to as "brush 41 etc.". The brush 41 and the like are arranged between the fin 32 of the heat exchanger 31 and the blower fan 38 so as to be rotatable about an axis. The brush 41 is slightly longer than the length of the blower fan 38 in the longitudinal direction so as to cover the entire area of the blower fan 38 in the longitudinal direction. The brush 41 etc. are arrange|positioned so that both ends penetrate the two side plates 33 (refer FIG. 12) arrange|positioned at the both ends of the heat exchanger 31. As shown in FIG.

刷子41等的兩端部被封閉構件封閉。封閉構件例如由馬達34(或者被馬達34驅動的齒輪、與其連結的接合器35等構件)、旋轉自如地保持刷子41等的端部的安裝構件36(參閱圖12)等構成。Both ends of the brush 41 and the like are closed by a closing member. The closing member is composed of, for example, a motor 34 (or a gear driven by the motor 34, an adapter 35 connected to the motor 34), a mounting member 36 (see FIG. 12) that rotatably holds the end of the brush 41 and the like.

刷子41具有複數個纖維部42和刷底座43。纖維部42是抵接於送風風扇38的抵接部。刷底座43是保持各纖維部42的基部。The brush 41 has a plurality of fiber parts 42 and a brush base 43. The fiber portion 42 is a contact portion that abuts on the blower fan 38. The brush base 43 is a base that holds each fiber portion 42.

如圖3所示，本實施方式中，刷底座43(基部)側視呈矩形狀，在上表面植絨複數個纖維部42(抵接部)。刷底座43收容於在保持部44所形成的收容部44a。As shown in FIG. 3, in this embodiment, the brush base 43 (base part) has a rectangular shape in a side view, and a plurality of fiber parts 42 (abutting parts) are flocked on the upper surface. The brush base 43 is accommodated in a accommodating portion 44 a formed in the holding portion 44.

圖示例中，保持部44側視為在矩形狀部位之下接合有倒T字狀部位的形狀。保持部44具有槽狀的收容部44a和軌道部44b。 收容部44a是可在送風風扇38的縱長方向(參閱箭頭A12)上滑動地收容刷底座43的部位。收容部44a形成為在送風風扇38的縱長方向上貫通保持部44的矩形狀部位的內部。收容部44a側視呈矩形狀，而且以可以使纖維部42在送風風扇38的縱長方向上移動的方式使其上方開口比纖維部42的粗細稍大。 軌道部44b是收容於在軸桿45所形成的收容部45a的部位。軌道部44b側視呈倒T字狀。軌道部44b形成於保持部44的縱長方向的整個區域。In the illustrated example, the holding portion 44 side is regarded as a shape in which an inverted T-shaped portion is joined under a rectangular portion. The holding portion 44 has a groove-shaped receiving portion 44a and a rail portion 44b. The accommodating portion 44a is a portion that slidably accommodates the brush base 43 in the longitudinal direction of the blower fan 38 (see arrow A12). The accommodating portion 44 a is formed to penetrate the inside of a rectangular portion of the holding portion 44 in the longitudinal direction of the blower fan 38. The accommodating portion 44 a has a rectangular shape in a side view, and the upper opening is slightly larger than the thickness of the fiber portion 42 so that the fiber portion 42 can be moved in the longitudinal direction of the blower fan 38. The rail part 44b is a part housed in the accommodating part 45a formed in the shaft 45. As shown in FIG. The rail 44b has an inverted T shape in a side view. The rail portion 44b is formed over the entire area of the holding portion 44 in the longitudinal direction.

軸桿45側視呈圓角的矩形狀。軸桿45具有槽狀的收容部45a。在圖示例中，軸桿45具有2個收容部45a。The shaft 45 has a rectangular shape with rounded corners when viewed from the side. The shaft 45 has a groove-shaped receiving portion 45a. In the illustrated example, the shaft 45 has two accommodating portions 45a.

收容部45a是可在送風風扇38的縱長方向(參閱箭頭A11)上滑動地收容軌道部44b的部位。收容部45a形成為在送風風扇38的縱長方向上貫通軸桿45的內部。收容部45a以可以使軌道部44b***而滑動的方式形成為與軌道部44b同樣的側視形狀且比軌道部44b稍大的尺寸。The accommodating portion 45a is a portion that slidably accommodates the rail portion 44b in the longitudinal direction of the blower fan 38 (see arrow A11). The accommodating portion 45 a is formed to penetrate the inside of the shaft 45 in the longitudinal direction of the blower fan 38. The accommodating portion 45a is formed in the same side view shape as the rail portion 44b and a size slightly larger than the rail portion 44b so that the rail portion 44b can be inserted and slid.

在該結構中，保持部44可以通過將軌道部44b***收容部45a進行滑動而容易地安裝於軸桿45。另外，保持部44可以藉由從收容部45a抽出軌道部44b的方式而從軸桿45卸下。另外，刷子41可以藉由使刷底座43***收容部44a進行滑動的方式而容易地安裝於保持部44。另外，刷子41可以藉由從收容部44a抽出刷底座43的方式而從保持部44卸下。In this structure, the holding portion 44 can be easily attached to the shaft 45 by inserting the rail portion 44b into the accommodating portion 45a and sliding. In addition, the holding portion 44 can be detached from the shaft 45 by pulling out the rail portion 44b from the accommodating portion 45a. In addition, the brush 41 can be easily attached to the holding portion 44 by inserting the brush base 43 into the accommodating portion 44a and sliding it. In addition, the brush 41 can be detached from the holding part 44 by pulling out the brush base 43 from the accommodating part 44a.

刷底座43及保持部44例如由樹脂構成。軸桿45例如由金屬或樹脂構成。The brush base 43 and the holding portion 44 are made of resin, for example. The shaft 45 is made of, for example, metal or resin.

刷子41的刷底座43及保持部44具有彈性。因此，如圖4所示，刷子41及保持部44在彎曲的狀態下相對於軸桿45可以安裝及拆卸(參閱箭頭A11a)。The brush base 43 and the holding portion 44 of the brush 41 have elasticity. Therefore, as shown in FIG. 4, the brush 41 and the holding part 44 are attachable and detachable with respect to the shaft 45 in the curved state (refer arrow A11a).

刷底座43的彈性力比軸桿45的彈性力大者為佳。也就是，刷底座43的剛性比軸桿45的剛性小者為佳。另外，刷底座43的彈性力最好比保持部44的彈性力大。也就是，刷底座43的剛性比保持部44的剛性小者為佳。由此，風扇清掃裝置40可以對刷子41及保持部44確保可以彎曲的合適的彈性，並且得到適於刷子41及保持部44向軸桿45安裝(***)的剛性。因此，風扇清掃裝置40可以實現刷子41及保持部44相對於軸桿45的安裝的容易化。此外，「彈性力」是指彈性體因外力而變形時，基於彈性而產生的力。The elastic force of the brush base 43 is preferably greater than the elastic force of the shaft 45. That is, the rigidity of the brush base 43 is preferably smaller than the rigidity of the shaft 45. In addition, the elastic force of the brush base 43 is preferably greater than the elastic force of the holding portion 44. That is, it is preferable that the rigidity of the brush base 43 is smaller than the rigidity of the holding portion 44. As a result, the fan cleaning device 40 can secure the brush 41 and the holding portion 44 with suitable flexibility that can be bent, and obtain the rigidity suitable for the installation (insertion) of the brush 41 and the holding portion 44 to the shaft 45. Therefore, the fan cleaning device 40 can facilitate the attachment of the brush 41 and the holding portion 44 to the shaft 45. In addition, "elastic force" refers to the force generated based on elasticity when an elastic body is deformed by an external force.

此外，保持部44優選具有不會因安裝於軸桿45時在軸桿45與保持部44之間產生的摩擦力而變形的程度的剛性。In addition, the holding portion 44 preferably has rigidity to such a degree that it is not deformed by the frictional force generated between the shaft 45 and the holding portion 44 when it is attached to the shaft 45.

如圖5所示，刷子41的纖維部42的間距P42比設於熱交換器31的鰭片32的間距P32小。圖5是表示風扇清掃裝置40的刷子41(清掃部)的纖維部42與熱交換器31的鰭片32的關係的圖。As shown in FIG. 5, the pitch P42 of the fiber part 42 of the brush 41 is smaller than the pitch P32 of the fin 32 provided in the heat exchanger 31. FIG. 5 is a diagram showing the relationship between the fiber portion 42 of the brush 41 (cleaning portion) of the fan cleaning device 40 and the fin 32 of the heat exchanger 31.

風扇清掃裝置40由於刷子41(清掃部)的纖維部42的間距P42比鰭片32的間距P32小，因此，可以以密集的狀態抵接於送風風扇38，可以高效地清掃送風風扇38。Since the pitch P42 of the fiber part 42 of the brush 41 (cleaning part) of the fan cleaning device 40 is smaller than the pitch P32 of the fin 32, it can abut against the blower fan 38 in a dense state, and can clean the blower fan 38 efficiently.

此外，刷子41為了即使在纖維部42撓曲的情況下，也可以使纖維部42抵接於送風風扇38進行清掃，而具有比較長的纖維部42。該纖維部42的長度例如比以下的過濾器清掃裝置60的刷子61的纖維部62長(參閱圖6)。In addition, the brush 41 has a relatively long fiber portion 42 in order to make the fiber portion 42 abut on the blower fan 38 for cleaning even when the fiber portion 42 is bent. The length of this fiber part 42 is longer than the fiber part 62 of the brush 61 of the following filter cleaning device 60, for example (refer FIG. 6).

圖6是風扇清掃裝置40的刷子41與過濾器清掃裝置60的刷子61的對比圖。過濾器清掃裝置60例如是用於清掃設於熱交換器31的周圍的過濾器(未圖示)的裝置。過濾器清掃裝置60與風扇清掃裝置40同樣地使用刷子61(參閱圖6)清掃過濾器(未圖示)。FIG. 6 is a comparison diagram of the brush 41 of the fan cleaning device 40 and the brush 61 of the filter cleaning device 60. The filter cleaning device 60 is, for example, a device for cleaning a filter (not shown) provided around the heat exchanger 31. The filter cleaning device 60 uses a brush 61 (see FIG. 6) to clean a filter (not shown) in the same manner as the fan cleaning device 40.

如圖6所示，刷子61與刷子41同樣地具有複數個纖維部62和刷底座63。纖維部62是抵接於未圖示的過濾器的抵接部。刷底座63是保持各纖維部62的基部。刷子61與刷子41同樣地構成為在刷底座63植絨複數個纖維部62。而且，如圖6對比所示地，刷子41的纖維部42的長度t42比刷子61的纖維部62的長度t62長。纖維部42的長度t42例如為10~30mm左右。此外，刷子41的被保持部44保持的部分的長度為幾mm左右。As shown in FIG. 6, the brush 61 has a plurality of fiber parts 62 and a brush base 63 similarly to the brush 41. The fiber portion 62 is a contact portion that abuts on a filter not shown. The brush base 63 is a base that holds each fiber portion 62. The brush 61 is configured to flock a plurality of fiber portions 62 on the brush base 63 in the same manner as the brush 41. Moreover, as shown in FIG. 6 for comparison, the length t42 of the fiber portion 42 of the brush 41 is longer than the length t62 of the fiber portion 62 of the brush 61. The length t42 of the fiber part 42 is about 10-30 mm, for example. In addition, the length of the portion of the brush 41 held by the holding portion 44 is about several mm.

風扇清掃裝置40由於刷子41(清掃部)的纖維部42的長度t42比刷子61的纖維部62的長度t62長，因此即使在纖維部42撓曲的情況下，也可以使纖維部42抵接於送風風扇38而清掃。In the fan cleaning device 40, since the length t42 of the fiber portion 42 of the brush 41 (cleaning portion) is longer than the length t62 of the fiber portion 62 of the brush 61, the fiber portion 42 can be brought into contact even when the fiber portion 42 is bent. It is cleaned by the blower fan 38.

如圖7所示，軸桿45是可安裝複數個(圖示例中，2個)刷子41的構造。圖7是表示刷子41(清掃部)向軸桿45安裝的例的立體圖。風扇清掃裝置40通過使軸桿45旋轉而交替使用複數個刷子41，從而可以使送風風扇38的累計清掃時間長期化。也就是，風扇清掃裝置40可以比較長的時間更換刷子41，可以連續清掃送風風扇38。As shown in Fig. 7, the shaft 45 has a structure in which a plurality of (two in the example of the figure) brushes 41 can be attached. FIG. 7 is a perspective view showing an example in which the brush 41 (cleaning part) is attached to the shaft 45. As shown in FIG. The fan cleaning device 40 rotates the shaft 45 to alternately use a plurality of brushes 41, so that the cumulative cleaning time of the blower fan 38 can be prolonged. That is, the fan cleaning device 40 can replace the brush 41 for a relatively long time, and can continuously clean the blower fan 38.

＜清掃部的安裝例＞ 空調機10的室內機11設置於室內比較高的位置。因此，例如，在進行刷子41(清掃部)的更換作業的情況下，作業者需要將手上舉至高的位置進行更換作業。因此，刷子41的更換作業難操作，另外給作業者帶去較大的負擔。＜Installation example of cleaning part＞ The indoor unit 11 of the air conditioner 10 is installed at a relatively high position indoors. Therefore, for example, when performing replacement work of the brush 41 (cleaning part), the operator needs to raise his hand to a high position to perform the replacement work. Therefore, the replacement operation of the brush 41 is difficult to operate, and it also imposes a large burden on the operator.

因此，在進行刷子41(清掃部)的更換作業的情況下，例如，最好使用圖8及圖9所示的安裝治具59。圖8及圖9是適於刷子41(清掃部)的安裝的安裝治具59的說明圖。圖8示出了安裝治具59的使用例。圖9示出了安裝治具59的結構。Therefore, when performing replacement work of the brush 41 (cleaning part), for example, it is preferable to use the mounting jig 59 shown in FIGS. 8 and 9. 8 and 9 are explanatory diagrams of an attachment jig 59 suitable for attachment of the brush 41 (cleaning part). FIG. 8 shows an example of use of the mounting jig 59. FIG. 9 shows the structure of the installation jig 59.

圖8示出了從框體21卸下裝飾框22的左側部分，然後將刷子41及保持部44(以下，簡稱為「刷子41」)安裝於軸桿45時的例。軸桿45配置於室內機11的內部。FIG. 8 shows an example in which the left part of the decorative frame 22 is removed from the frame body 21, and then the brush 41 and the holding portion 44 (hereinafter referred to as “brush 41”) are attached to the shaft 45. The shaft 45 is arranged inside the indoor unit 11.

如圖8所示，風扇清掃裝置40例如通過將安裝治具59安裝於軸桿45，並使刷子41在安裝治具59中穿過，從而可以將刷子41安裝於軸桿45。As shown in FIG. 8, the fan cleaning device 40 can attach the brush 41 to the shaft 45 by, for example, attaching the installation jig 59 to the shaft 45 and passing the brush 41 through the installation jig 59.

安裝治具59是用於將刷子41安裝於軸桿45的管。安裝治具59構成為，長度比刷子41短，且可彎曲。The mounting jig 59 is a tube for mounting the brush 41 to the shaft 45. The installation jig 59 is configured to be shorter than the brush 41 and bendable.

如圖9所示，在安裝治具59的內部，從其中一方的端面安裝治具59a橫貫至另一方的端面安裝治具59b，形成有貫通的貫通孔OP44。另外，在安裝治具59的其中一方的端面安裝治具59a形成有與軸桿45的端部嵌合的槽狀的嵌合部OP45。As shown in Fig. 9, in the inside of the mounting jig 59, a through hole OP44 is formed across from one end surface mounting jig 59a to the other end surface mounting jig 59b. In addition, a groove-shaped fitting part OP45 that is fitted to the end of the shaft 45 is formed on one end surface of the fitting jig 59.

安裝治具59通過端面安裝治具59a的嵌合部OP45與軸桿45的端部嵌合而安裝於室內機11。The attachment jig 59 is attached to the indoor unit 11 by fitting the fitting portion OP45 of the end surface attachment jig 59a to the end of the shaft 45.

刷子41從另一方的端面安裝治具59b***貫通孔OP44中，朝向室內機11的裡側(圖的右方向)在送風風扇38的縱長方向上滑動。由此，刷子41從另一方的端面安裝治具59b通到一方的端面安裝治具59a。然後，刷子41的前端部穿過一方的端面安裝治具59a時，保持部44的軌道部44b***軸桿45的收容部45a。刷子41在該狀態下朝向室內機11的裡側(圖的右方向)進一步在送風風扇38的縱長方向上滑動，從而安裝於軸桿45。之後，將卸下的裝飾框22的左側部分安裝於框體21。由此，刷子41的安裝作業完成。 The brush 41 is inserted into the through hole OP44 from the other end surface mounting jig 59b, and slides in the longitudinal direction of the blower fan 38 toward the inner side of the indoor unit 11 (right direction in the figure). Thereby, the brush 41 passes from the other end surface mounting jig 59b to one end surface mounting jig 59a. Then, when the front end portion of the brush 41 passes through one end surface to install the jig 59a, the rail portion 44b of the holding portion 44 is inserted into the receiving portion 45a of the shaft 45. In this state, the brush 41 further slides in the longitudinal direction of the blower fan 38 toward the inner side of the indoor unit 11 (the right direction in the figure), and is attached to the shaft 45. After that, the left part of the removed decorative frame 22 is attached to the frame 21. Thus, the installation work of the brush 41 is completed.

<空調機的主要特徵> <Main features of air conditioners>

(1)空調機10的風扇清掃裝置40通過僅使刷子41(清掃部)滑動，便可以容易地進行刷子41的安裝及拆卸。因此，風扇清掃裝置40可以容易地進行刷子41的更換。另外，風扇清掃裝置40可以在將來研發出被賦予了特殊的附加功能的清掃部等的情況下，容易地更換為該清掃部等。 (1) The fan cleaning device 40 of the air conditioner 10 can easily attach and detach the brush 41 by simply sliding the brush 41 (cleaning part). Therefore, the fan cleaning device 40 can easily replace the brush 41. In addition, the fan cleaning device 40 can be easily replaced with the cleaning unit or the like when a cleaning unit or the like to which a special additional function is provided in the future is developed.

此外，風扇清掃裝置40的清掃部不僅為刷子41，也可以由海綿、橡膠等彈性材料構成。 In addition, the cleaning part of the fan cleaning device 40 is not only the brush 41, but may also be made of elastic materials such as sponge and rubber.

(2)刷子41等以容易***軸桿45的收容部45a的方式設定保持腰部的強度。由此，刷子41等可以從軸桿45的旁邊抽出、***，從而容易地更換。 (2) The brush 41 and the like are set to maintain the strength of the waist so as to be easily inserted into the receiving portion 45a of the shaft 45. Thereby, the brush 41 etc. can be withdrawn and inserted from the side of the shaft 45, and can be replaced easily.

(3)風扇清掃裝置40可以將刷子41(清掃部)的刷底座43(基部)及保持部44彎曲而在軸桿45安裝(***)及 拆卸(抽出)。也就是，風扇清掃裝置40可以將刷底座43及保持部44彎曲，並進行更換作業。這樣的風扇清掃裝置40可以容易地進行狹小空間的刷子41等的更換作業(例如，設置於房間的端部附近的空調機10的刷子41等的更換作業)。 (3) The fan cleaning device 40 can bend the brush base 43 (base) and the holding part 44 of the brush 41 (cleaning part) to be installed (inserted) on the shaft 45 and Disassemble (extract). That is, the fan cleaning device 40 can bend the brush base 43 and the holding portion 44 and perform replacement work. Such a fan cleaning device 40 can easily perform replacement work of the brush 41 and the like in a small space (for example, replacement work of the brush 41 and the like of the air conditioner 10 installed near the end of the room).

此外，刷底座43(基部)比軸桿45容易彎曲者為佳。另外，刷底座43(基部)比保持部44容易彎曲者為佳。另外，保持部44具有不會由於安裝於軸桿45時在軸桿45與保持部44之間產生的摩擦力而變形的程度的剛性者為佳。 In addition, the brush base 43 (base) is preferably easier to bend than the shaft 45. In addition, it is preferable that the brush base 43 (base portion) bends more easily than the holding portion 44. In addition, it is preferable that the holding portion 44 has a rigidity that is not deformed due to the frictional force generated between the shaft 45 and the holding portion 44 when it is attached to the shaft 45.

(4)如圖12所示，刷子41等的兩端部例如被馬達34、接合器35、安裝構件36等封閉構件封閉。這些封閉構件可以任意卸下。風扇清掃裝置40通過卸下這些封閉構件，可以更換刷子41、保持部44。此外，在將馬達34作為封閉構件使用的情況下，可以削減相應的零件個數。 (4) As shown in FIG. 12, both ends of the brush 41 and the like are closed by closing members such as the motor 34, the adapter 35, and the mounting member 36, for example. These closing members can be detached arbitrarily. The fan cleaning device 40 can replace the brush 41 and the holding part 44 by removing these closing members. In addition, when the motor 34 is used as a closing member, the number of corresponding parts can be reduced.

如上所述，根據本實施方式1的空調機10，僅通過使刷子41滑動，便可以容易地進行風扇清掃裝置40的刷子41的安裝及拆卸，因此，可以容易地進行刷子41的更換。 As described above, according to the air conditioner 10 of the first embodiment, only by sliding the brush 41, the brush 41 of the fan cleaning device 40 can be easily attached and detached. Therefore, the brush 41 can be easily replaced.

[實施方式2] [Embodiment 2]

實施方式1的風扇清掃裝置40的刷子41(參閱圖3及圖5)在刷底座43的上表面的整個區域植絨纖維部42。這樣的風扇清掃裝置40在清掃送風風扇38時，刷子41抵接於送風風扇38，因此，在使刷子41等旋轉時，對刷子41施加負荷，刷子41容易變髒。The brush 41 (refer to FIG. 3 and FIG. 5) of the fan cleaning device 40 of Embodiment 1 flocks the fiber part 42 in the whole area|region of the upper surface of the brush base 43. As shown in FIG. When such a fan cleaning device 40 cleans the blower fan 38, the brush 41 abuts on the blower fan 38. Therefore, when the brush 41 or the like is rotated, a load is applied to the brush 41, and the brush 41 is likely to become dirty.

因此，在本實施方式2中，提供一種風扇清掃裝置40A，在使刷子41等旋轉時，減輕施加於刷子41的負荷，並且使刷子41難以變髒。Therefore, in the second embodiment, a fan cleaning device 40A is provided that reduces the load applied to the brush 41 when the brush 41 or the like is rotated, and makes the brush 41 less likely to become dirty.

以下，參閱圖10至圖12，對本實施方式2的風扇清掃裝置40A的刷子41A(清掃部)的結構進行說明。圖10及圖11分別是表示風扇清掃裝置40A的刷子41A的結構的主視圖。圖12是表示風扇清掃裝置40A的刷子41A的兩端部的結構的主視圖。Hereinafter, referring to FIGS. 10 to 12, the structure of the brush 41A (cleaning part) of the fan cleaning device 40A of the second embodiment will be described. 10 and 11 are front views showing the structure of the brush 41A of the fan cleaning device 40A, respectively. Fig. 12 is a front view showing the structure of both ends of the brush 41A of the fan cleaning device 40A.

圖10示出了從保持部44抽出後述的刷子41A，並且從軸桿45抽出保持部44的狀態。圖11示出了後述的刷子41A收容於保持部44，並且保持部44收容於軸桿45的狀態。FIG. 10 shows a state where the brush 41A, which will be described later, is drawn out from the holding part 44 and the holding part 44 is drawn out from the shaft 45. FIG. 11 shows a state in which a brush 41A, which will be described later, is housed in the holder 44 and the holder 44 is housed in the shaft 45.

如圖10及圖11所示，與實施方式1的風扇清掃裝置40(參閱圖3及圖5)比較，本實施方式的風扇清掃裝置40A的不同點在於取代刷子41而具備刷子41A。As shown in FIGS. 10 and 11, compared with the fan cleaning device 40 of Embodiment 1 (see FIGS. 3 and 5 ), the fan cleaning device 40A of the present embodiment is different in that it includes a brush 41A instead of the brush 41.

刷子41A在刷底座43具有植絨有纖維部42的植絨區域43a、和未種植纖維部42的非植絨區域43b。植絨區域43a形成於刷底座43的其中一方的端部或兩端部以外的部分。非植絨區域43b形成於刷底座43的其中一方的端部或兩端部。The brush 41A has a flocking area 43a where the fiber part 42 is flocked and a non-flocking area 43b where the fiber part 42 is not planted on the brush base 43. The flocking area 43a is formed in a part other than one end or both ends of the brush base 43. As shown in FIG. The non-flocking area 43b is formed at one end or both ends of the brush base 43.

如圖11所示，本實施方式的風扇清掃裝置40A以可以用人手容易地保持刷底座43的方式在刷底座43具有把手部43c。As shown in FIG. 11, the fan cleaning device 40A of this embodiment has the handle part 43c in the brush base 43 so that the brush base 43 can be easily hold|maintained by a human hand.

把手部43c是形成於刷底座43的端部的非植絨區域43b中進一步成為端部的部位。如圖11所示，在刷子41A等安裝於軸桿45的狀態下，把手部43c從保持部44的端部突出至外部。The handle part 43c is a part which becomes an end part in the non-flocking area 43b formed in the end part of the brush base 43 further. As shown in FIG. 11, in a state where the brush 41A and the like are attached to the shaft 45, the handle portion 43c protrudes from the end of the holding portion 44 to the outside.

風扇清掃裝置40A藉由人手把持該把手部43c的方式而可以從保持部44容易地卸下刷子41A。此時，作業者操作把手部43c，手動改變刷子41A等的朝向，經此，可以在碰不到送風風扇38、熱交換器31的位置更換刷子41A等。The fan cleaning device 40A can easily remove the brush 41A from the holding portion 44 by holding the handle portion 43c by a human hand. At this time, the operator manipulates the handle portion 43c to manually change the orientation of the brush 41A and the like. With this, the brush 41A and the like can be replaced at a position where the blower fan 38 and the heat exchanger 31 are not touched.

如圖12所示，在室內機11的內部，刷子41A等配置為其兩端部貫通在熱交換器31的兩端部所配置的2個側板33。刷子41A等的其中一方的端部被馬達34(或被馬達34驅動的齒輪、與之連結的接合器35等構件)封閉。另外，刷子41A等的另一方的端部被安裝構件36等封閉。馬達34(或被馬達34驅動的齒輪、與之連結的接合器35等構件)和安裝構件36旋轉自如地保持刷子41A等。As shown in FIG. 12, inside the indoor unit 11, the brush 41A etc. are arrange|positioned so that both ends penetrate the two side plates 33 arrange|positioned at the both ends of the heat exchanger 31. As shown in FIG. One end of the brush 41A and the like is closed by the motor 34 (or a gear driven by the motor 34, and a member such as an adapter 35 connected thereto). In addition, the other end of the brush 41A and the like is closed by the attachment member 36 and the like. The motor 34 (or the gear driven by the motor 34, the adapter 35 connected thereto, etc.) and the mounting member 36 rotatably hold the brush 41A and the like.

此外，在圖示例中，馬達34配置於側板33的外側，而且構成為其旋轉軸34a經由齒輪、與之連結的接合器35等構件連結於刷子41A等。In the example shown in the figure, the motor 34 is arranged outside the side plate 33, and the rotating shaft 34a is connected to the brush 41A or the like via a gear, an adapter 35 connected thereto, and the like.

風扇清掃裝置40A在清掃送風風扇38時，在使刷子41A等旋轉時，在刷子41A的兩端部纖維部42不碰到熱交換器31的側板33的方式在纖維部42設置有非植絨區域43。因此，風扇清掃裝置40A在使刷子41A等旋轉時，可以減輕施加於刷子41A的負荷。另外，風扇清掃裝置40A可以使刷子41A難以變髒。When the fan cleaning device 40A cleans the blower fan 38, when the brush 41A or the like is rotated, the fiber portion 42 at both ends of the brush 41A does not touch the side plate 33 of the heat exchanger 31, and the fiber portion 42 is provided with non-flocking. Area 43. Therefore, when the fan cleaning device 40A rotates the brush 41A and the like, the load applied to the brush 41A can be reduced. In addition, the fan cleaning device 40A can prevent the brush 41A from becoming dirty.

另外，風扇清掃裝置40A在刷底座43設有把手部43c，因此可以從熱交換器31的旁邊的空間容易地抽出刷子41。In addition, since the fan cleaning device 40A is provided with the handle portion 43c on the brush base 43, the brush 41 can be easily drawn out from the space beside the heat exchanger 31.

如上所述，根據本實施方式2，與實施方式1同樣地，僅通過使刷子41A滑動，便可以容易地進行風扇清掃裝置40A的刷子41A的安裝及拆卸，因此，可以容易地進行刷子41A的更換。 而且，根據本實施方式2，與實施方式1相比，可以減輕清掃送風風扇38時施加於刷子41A的負荷。另外，可以使刷子41A難以變髒。As described above, according to the second embodiment, similarly to the first embodiment, only by sliding the brush 41A, the brush 41A of the fan cleaning device 40A can be easily installed and removed. Therefore, the brush 41A can be easily installed and removed. replace. Furthermore, according to the second embodiment, compared with the first embodiment, the load applied to the brush 41A when cleaning the blower fan 38 can be reduced. In addition, the brush 41A can be made difficult to become dirty.

此外，本發明不限定於前述的實施方式，在不脫離本發明的宗旨的範圍內，可以進行各種變更、變形。In addition, the present invention is not limited to the aforementioned embodiments, and various changes and modifications can be made without departing from the spirit of the present invention.

例如，前述的實施方式是為了易於理解地說明本發明的宗旨而詳細地說明的例子。因此，本發明並非限定於必須具備所說明的全部的構成要素。另外，本發明可以對某構成要素追加其它構成要素、將一部分構成要素變更成其它構成要素。另外，本發明也可以刪除一部分構成要素。For example, the foregoing embodiment is an example explained in detail in order to easily understand the gist of the present invention. Therefore, the present invention is not limited to having all the components described. In addition, in the present invention, other components may be added to a certain component, and some components may be changed to other components.
