Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The air-conditioning indoor unit of the invention can be a cabinet type indoor unit, and the person skilled in the art can apply the invention to other scenes without departing from the principle of the invention. For example, the present application can also be applied to a wall-mounted indoor unit. Specifically, the indoor unit of an air conditioner includes a cabinet, in which a water washing device 10 is provided, and the water washing device 10 is used to purify and humidify an air flow passing therethrough, thereby improving air quality. The water washing device 10 is electrically connected with a main control device of the air conditioner, and the water washing device 10 is powered by the main control device.
It will be appreciated that as the air conditioner operates for a longer period of time, the amount of water in the water washing device 10 will gradually decrease, requiring the user to replenish water in a timely manner. As mentioned above, in the conventional water washing apparatus 10, a sensor generally detects the position of the water tank 200, and a feedback signal is generated according to the position of the water tank 200 to control whether a main control device (an electronic control computer) of the indoor unit switches on or off the water washing apparatus 10. In fact, the entire water washing apparatus 10 is still powered in this power-off mode, but is not powered. Therefore, the water washing device 10 is low in protection performance and safety coefficient, and a user has a large potential safety hazard in the water replenishing process. Therefore, the invention can realize real power-off by improving the conductive structure of the water washing device 10, thereby ensuring that a user can safely carry out water replenishing operation. The structure of the water washing apparatus 10 will be described in detail below.
Fig. 1 is a schematic structural view of a water washing apparatus 10 according to an embodiment of the present invention. Referring to fig. 1 in conjunction with fig. 2-5, the water washing apparatus 10 includes at least a housing 100, a water tank 200, and a contact switch 300. One side of the housing 100 is recessed into the housing 100 to form a receiving chamber 110, the water tank 200 is operably pulled out or pushed into the receiving chamber 110, and the contact switch 300 is disposed between the water tank 200 and an inner wall of the receiving chamber 110, and is configured such that the contact switch 300 is turned off when the water tank 200 is pulled out of the receiving chamber 110, and the contact switch 300 is turned on when the water tank 200 is completely pushed into the receiving chamber 110.
According to the washing device 10 provided by the embodiment of the invention, the contact switch 300 is arranged between the water tank 200 and the inner wall of the accommodating cavity 110, when water needs to be supplemented into the water tank 200, the water tank 200 can be pulled out of the accommodating cavity 110, the contact switch 300 is switched off at the moment, the whole washing device 10 is in a power-off state, a user cannot get an electric shock accidentally during water supplementing, and the protection performance and the safety coefficient of the washing device 10 are improved. After the water replenishing is completed, the water tank 200 can be completely pushed into the accommodating cavity 110, so that the contact switch 300 is switched on, and at the moment, the water washing device 10 is in a switching-on state and can normally work to purify and humidify the air flow.
In an alternative embodiment, the contact switch 300 may include a plug 310 and a socket 320, the plug 310 is adapted to the socket 320, wherein one end of the plug 310 is fixed to an end surface of the pushing end of the water tank 200, the other end extends toward the inside of the receiving cavity 110, and the socket 320 is fixed to an inner wall of the receiving cavity 110 opposite to the pushing end of the water tank 200 and has a socket 321 formed thereon for the plug 310 to be inserted.

In an alternative embodiment, a water level detecting device 210 is provided in the water tank 200, and the water level detecting device 210 is used to detect the height of the water level in the water tank 200, so that the user can clearly know the water level in the water tank 200. The water level detecting means 210 may be a liquid level sensor, a magnetic float, or the like.
Further, the reminding device 130 is further configured to send a second prompt signal for adding water into the water tank 200 when it is detected that the water level in the water tank 200 is lower than the preset height, where the second prompt signal may be a voice prompt, for example, "the current water level is lower, please confirm whether to add water into the water tank 200", because the water consumption in the water tank 200 is not fixed, the water consumption is dry in winter, and the water consumption is relatively high, the water consumption condition in the water tank 200 can be timely fed back to the user through the additionally arranged reminding device 130, and the use experience of the user is improved.
In this embodiment, a sliding assembly is further disposed between the water tank 200 and the accommodating cavity 110, and the sliding assembly may include two sliding rails 410 and two sliding rails 420, wherein the two sliding rails 410 are relatively connected to two sides of the water tank 200, the two sliding rails 420 are relatively connected to inner walls of two sides of the accommodating cavity 110, and the two sliding rails 410 are respectively slidably connected to the two sliding rails 420, so that a user can push and pull the water tank 200 conveniently and laborsavingly through the cooperation of the sliding rails 410 and the sliding rails 420.
According to any one or a combination of multiple optional embodiments, the embodiment of the present invention can achieve the following beneficial effects:
according to the washing device 10 provided by the embodiment of the invention, the contact switch 300 is arranged between the water tank 200 and the inner wall of the accommodating cavity 110, when water needs to be supplemented into the water tank 200, the water tank 200 can be pulled out of the accommodating cavity 110, the contact switch 300 is switched off at the moment, the whole washing device 10 is in a power-off state, a user cannot get an electric shock accidentally during water supplementing, and the protection performance and the safety coefficient of the washing device 10 are improved. After the water replenishing is completed, the water tank 200 can be completely pushed into the accommodating cavity 110, so that the contact switch 300 is switched on, and at the moment, the water washing device 10 is in a switching-on state and can normally work to purify and humidify air flow.
Further, by setting the insertion hole 321 to be a tapered shape, when the insertion column 310 and the insertion hole 321 are slightly misaligned, the insertion column 310 can still be guided to be smoothly inserted into the insertion hole 321, so that the safety and effectiveness of the contact switch 300 are ensured; the limiting column 112 can stop the water tank 200 after the water tank 200 is pushed in place, so that the phenomenon that the inserting column 310 and the socket 320 are damaged due to the fact that the water tank 200 is pushed hard in the pushing process is avoided, and the service life of the contact switch 300 is prolonged.
