Embodiment approach 1

[0030] This Embodiment 1 intends to provide the air conditioner 10 which can hold down the usage cost by being able to replace only the cleaning part. In addition, this Embodiment 1 also intends to provide the air conditioner 10 which can be easily replaced with the cleaning part etc., when the cleaning part etc. which are provided with the special additional function are developed in the future.

[0031]

[0032] Below, refer to figure 1 , the overall configuration of the air conditioner 10 according to Embodiment 1 will be described. figure 1 It is a schematic diagram showing the overall configuration of the air conditioner 10 according to the first embodiment.

[0033] Such as figure 1 As shown, the air conditioner 10 has an indoor unit 11 disposed indoors and an outdoor unit 12 disposed outdoors.

[0034] The indoor unit 11 draws indoor air into the inside, and passes the sucked indoor air through the heat exchanger 31 (refer to figure 2 ) to obtain conditioned air ...

Embodiment approach 2

[0088] The brush 41 of the fan cleaning device 40 of Embodiment 1 (refer to image 3 and Figure 5 ) flocking the fiber portion 42 over the entire area of ​​the upper surface of the brush base 43. In such a fan cleaning device 40 , when cleaning the blower 38 , the brush 41 is in contact with the blower 38 , and therefore, when the brush 41 etc. are rotated, a load is applied to the brush 41 and the brush 41 becomes dirty easily.

[0089] Therefore, in this Embodiment 2, 40 A of fan cleaning apparatuses are provided, when rotating the brush 41 grade|etc., it reduces the load applied to the brush 41, and makes it difficult for the brush 41 to become dirty.

[0090] Below, refer to Figure 10 to Figure 12 Next, the configuration of the brush 41A (cleaning unit) of the fan cleaning device 40A according to the second embodiment will be described. Figure 10 and Figure 11 Each is a front view showing the structure of the brush 41A of the fan cleaning device 40A. Figure 12 It...

Abstract

The air conditioner (10) includes a heat exchanger (31), a blower (38), and a fan cleaning device (40) for cleaning the blower. The fan cleaning device has a rotary shaft (45), a motor (34) that rotates the rotary shaft in a direction around the shaft, and a cleaning unit (brush (41)) attached to the rotary shaft. The cleaning part and the rotating shaft are separated.

Description

technical field [0001] The present invention relates to air conditioners. Background technique [0002] Generally, the longer an air conditioner with a blower inside is used, the more dust adheres to the blower. As a result, the air volume of the air conditioner may decrease and power consumption may increase. In addition, the air conditioner may generate mold or the like due to the adhesion of dust, and may be unsanitary. Therefore, there is provided an air conditioner provided with a fan cleaning device that removes dust adhering to the blower and cleans the blower (for example, refer to Patent Document 1). The air conditioner described in Patent Document 1 includes a fan cleaning device and a control device for controlling the fan cleaning device, and has a normal operation mode in which conditioned air is blown indoors, and a fan cleaning operation mode in which the fan rotates at a low speed and moves the fan cleaning device. The fan cleaning device is configured to ...
