Detailed Description

An evaporator cleaning structure can be used for cleaning an evaporator 6 in an automatic cleaning air conditioner or other heat exchange systems, and can also be used for cleaning other equipment if necessary, such as shown in figures 1-2, and comprises a volute 8 and a supply assembly.

The volute 8 and the evaporator 6 are fixedly mounted on the frame 4, the air outlet 7 of the volute 8 is opposite to the evaporator 6, the volute 8 conventionally belongs to a centrifugal fan, therefore, the volute 8 is also connected with a fan, but the volute can also be connected with other non-centrifugal fans, as long as a normal air supply function can be met, the air supply through the volute 8 and the fan and the evaporator 6 complete a sufficient heat exchange process, and the process often causes the evaporator 6 to be attached to the surface of more dust or impurities.

In order to facilitate the connection between the volute 8 and the supply assembly, as shown in fig. 1-2, an inlet 1 is formed at the bottom of the volute 8, and the supply assembly includes a storage tank 5 for storing a cleaning medium, a pump body 3 for pumping the cleaning medium in the storage tank 5 into the volute 8, and a pipeline 2 for communicating the storage tank 5, the pump body 3 and the volute 8. This pump body 3 adopts the self priming pump, and storage tank 5 also can be for general basin, when needs self-cleaning, can be by the manual work press the corresponding button on the controller to the self priming pump receives control to open, passes through pipeline 2 pump with the cleaning medium in the storage tank 5 and sends to in the spiral case 8.

Because the setting of spiral case 8 is originally for abundant heat transfer, therefore air-out position just right with evaporimeter 6 in the spiral case 8, and the cleaning medium who spouts from spiral case 8 air outlet 7 this moment just in time is relative with the dust attached position, can play comparatively good cleaning performance.

Of course, the water receiving tray 9 is installed below the evaporator 6, and the water receiving tray is also connected with a drainage pipeline for discharging the condensed water on the evaporator 6 at ordinary times and the cleaning medium generated during automatic cleaning together, so that the condensed water and the cleaning medium are prevented from flowing out, and the use experience of a user is prevented from being influenced.

In this embodiment, the cleaning medium may be water, and certainly, in another embodiment, the cleaning medium may also be water-based spray, and a joint between the pipeline 2 and the inlet 1 in the supply assembly may be set with an installation angle, so as to ensure that the cleaning medium can move along the inner side wall of the volute 8 after entering the volute 8, improve kinetic energy after the cleaning medium is sprayed, and facilitate improvement of a cleaning effect.

In another embodiment, the storage tank may be disposed at a higher position, and the height of the storage tank is higher than that of the inlet, or the storage tank may be higher than that of the volute, and only a communicating pipe is disposed between the storage tank and the inlet, and an electric valve is mounted on the pipe. When the automatic cleaning is needed to be started, the valve is controlled to be opened, and the cleaning medium in the storage tank automatically flows downwards and enters the volute due to the high position, so that the installation of a pump is omitted, and part of pipeline cost is saved. Furthermore, in order to utilize potential energy effect brought by the height, the inlet can be arranged at the top of the volute and is obliquely arranged towards one side of the evaporator, so that moisture in the storage tank can be favorably and directly rushed towards the evaporator through the guiding effect of the volute, and a better cleaning effect is achieved.

Through the aforesaid setting, will regard as cleaning medium's output device with the supporting current equipment spiral case of evaporimeter, the position on the evaporimeter is attached to impurity in the accurate flush air of cleaning medium is guaranteed to the flow path that can combine the air supply on the one hand, reach good cleaning performance, on the other hand need not extra installation washing output device, reduce the space of equipment and occupy, adopt extra cleaning medium also can be more thorough simultaneously with the evaporimeter sanitization, also can maintain indoor temperature's stability for current self-cleaning mode.

Of course, as shown in fig. 1-2, the impeller 10 is disposed inside the volute 8, and the cleaning medium entering the bottom of the volute 8 from the inlet 1 can be rotated upward along with the rotation of the impeller 10, and is thrown out from the air outlet 7 to the evaporator 6 opposite to the air outlet 7, so as to achieve the cleaning effect.

It should be noted that, necessary additives, such as a detergent or a deicing agent, may be added to the cleaning medium, and the additives may be selected according to the needs of the actual situation, for example, some oil-soluble additives may be added when oil needs to be removed, so as to achieve the corresponding effect.

The present embodiment also discloses an air conditioner including the evaporator 6 cleaning structure as described above.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
