Example 2

This embodiment is a window type air conditioner provided with the muffler of embodiment 1, and as shown in fig. 3 to 5, the window type air conditioner includes a base plate 4 and a cover body 7, and the cover body 7 covers the base plate 4. An inner air duct system and an outer air duct system 3 are arranged on the chassis 4, the inner air duct system faces indoors, the outer air duct system 3 faces outdoors, the inner air duct system and the outer air duct system 3 are separated by a partition plate 5, the inner air duct system comprises an inner air duct component 23, an evaporator 21 and a panel 22, the inner air duct component 23 is arranged on one side of the partition plate 5 close to the panel 22, and the evaporator 21 is arranged between the inner air duct component 23 and the panel 22. The outer air duct system 3 includes an outer air duct member 32 and a condenser 31. The fan 321 is provided on the outer air duct member 32. The cover body 7, the condenser 31 component and the mask component jointly form a box type structure of the window type air conditioner. An electrical box and a compressor 6 are arranged between the outer air duct system 3 and the inner air duct system. The box body is arranged between the outer air duct system 3 and the inner air duct system, and the position which can be set comprises that the box body is arranged on one side of the outer air duct component 32 close to the partition plate 5, arranged on the partition plate 5 or arranged on the cover body 7. Since the noise source of the window type air conditioner is mainly from the compressor 6 and the compressor 6 generates a large amount of heat during operation, it is preferable that the case is disposed above the compressor 6 and fixed to the top of the cover 7.

Because the evaporator 21 of window air conditioner can produce the comdenstion water in the course of the work, and the comdenstion water directly arranges to the chassis 4 through the hose 142, because the chassis 4 has certain degree of depth, can store the comdenstion water, the water pump 143 of muffler directly sets up and extracts the comdenstion water on the chassis 4 and spray on the chassis 4. Alternatively, a water collecting box is arranged on the chassis 4, condensed water is discharged into the water collecting box through a hose 142, and a water pump 143 of the silencer is connected with the water collecting box to extract water in the water collecting box for spraying. So, just can reuse the comdenstion water that evaporimeter 21 produced, avoided the comdenstion water to arrange outward and cause the influence to external environment on the one hand, on the other hand the comdenstion water is in time cleaned the box body 111 of muffler after the nozzle blowout of shower head 141, the comdenstion water of flow has the lower temperature in the through-hole 1111 of box body 111, still can cool down to heating parts such as compressor 6, improve the operating efficiency and the life-span of compressor 6, also make the whole operational environment's of muffler temperature reduction simultaneously, improve the noise reduction effect and the life of muffler.

The window type air conditioner of the embodiment also executes a cleaning spraying program after the operation is finished, namely, the spraying device is controlled to extract condensed water of the air conditioner to clean and spray the box body, and the spraying is stopped after the first preset time is reached. The method specifically comprises the following steps: the water pump 143 is controlled to start, the water pump 143 pumps the condensed water on the cover plate 112 and then sprays the condensed water on the box body 111 through the spray head 141, and the water pump 143 stops running after the first preset running time is reached. The preset operation time can be set by user self, or recorded in the controller of the air conditioner without user change when the controller is shipped from factory.

Further, based on the scheme, the air conditioner can be controlled to execute the cleaning spraying program according to the spraying instruction sent by the user. For example, a spray control button is provided on a remote controller of an air conditioner, and a user sends a control instruction through the control button of the remote controller of the air conditioner, or a mobile terminal of the user is connected to an air conditioner network and sends the control instruction through the mobile terminal.

Further, based on the above scheme, in order to ensure that the evaporator 21 generates enough condensed water, it is preferable to control the air conditioner to perform the cleaning spraying program after the air conditioner finishes operating for the second preset time. For example, after the air conditioner receives the shutdown signal 30s, the water pump 143 is started to control the water pump 143 to start.

Further, based on the above solution, in order to avoid the situation that the water level of the condensed water in the chassis 4 or the water collecting box is too low to cause the water pump 143 to be unable to pump the condensed water, a water level detecting device is disposed in the chassis 4 or the water collecting box, the water level of the condensed water on the chassis 4 is detected during the cleaning spraying process, and whether the water level in the chassis 4 or the water collecting box can be pumped by the water pump 143 is determined by the water level detecting device. When the water level is lower than the preset water level, the water pump 143 is controlled to stop, and the cleaning spraying program is stopped.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
