It can be understood that the first water outlet 111 and the second water outlet 112 are located at different positions on the sidewall of the water inlet region 11, for example, the first water outlet 111 and the second water outlet 112 are arranged at intervals in the up-down direction and the circumferential direction, and when the water plug 20 is moved to block the first water outlet 111, the second water outlet 112 is in an open state. When the water plug 20 moves to block the second water outlet 112, the first water outlet 111 is in an open state, wherein in a switching process of switching the water plug 20 from a state of blocking the first water outlet 111 to a state of blocking the second water outlet 112 or from the state of blocking the second water outlet 112 to the state of blocking the first water outlet 111, the first water channel 12 and the second water channel 13 are both communicated with the water inlet area 11, so that the switching of the water channels is simple and reliable.

Specifically, the pressure plate 21 can limit the movement displacement of the water plug 20 to prevent the water plug 20 from falling off the water inlet area 11 when moving. When the push rod 22 is driven to move, the water plug 20 can be driven to move, so that the water plug 20 can open the first water outlet 111 or the second water outlet 112. Therefore, the structure of the switching assembly 2 is simple, and the water plug 20 can effectively control the waterway conduction of the first waterway 12 and the second waterway 13.
In particular, the pressure plate 21 may be fixed to the water distribution tray 1 in any manner, for example, may be fixed to the water distribution tray 1 by screws.

Specifically, when the water distribution device 100 is applied to the air conditioner 1000, the floater 23 is disposed on the base plate 300, the suction pump body 3 pumps the condensed water in the base plate 300 to the water inlet region 11, the condensed water in the water inlet region 11 may flow to the water distribution region 10 through the first water channel 12, the condensed water in the water distribution region 10 may flow to the condenser 200 through the plurality of first water distribution ports 101, and the heat of the condenser 200 may evaporate the condensed water. The condensate water which is not evaporated flows to the chassis 300, the condensate water slowly rises in the chassis 300, the float 23 rises along with the rise of the water level in the process of the rise of the water level, the push rod 22 is driven to move when the float 23 rises to lift the water plug 20, the water plug 20 moves to gradually close the first water outlet 111 and gradually open the second water outlet 112, and the condensate water in the water inlet area 11 flows to the second water channel 13 from the second water outlet 112 to be discharged to the water tank 400.
After the condensed water flows to the water tank 400, the level of the condensed water in the base plate 300 is lowered, the float 23 descends to drive the ejector rod 22 to move so as to lower the water plug 20, the water plug 20 descends to close the second water outlet 112, the condensed water flows to the water distribution area 10 through the first water outlet 111, and then the condensed water flows to the condenser 200 through the first water distribution port 101.

Therefore, the speed of the condensed water flowing to the plurality of first water distribution openings 101 can be increased, and the evaporation speed of the condensed water is increased.
Specifically, as shown in fig. 1 to 7, each of the inlet cavities 113 may be formed in a cylindrical shape, each of the water stoppers 20 includes a first portion 201 and a second portion 202 having different diameters, the first portion 201 has a smaller diameter than the second portion 202, the water stopper 20 is moved to be engaged with an inner circumferential wall of the corresponding inlet cavity 113, and when the water stopper 20 is moved upward, the second portion 202 blocks the first outlet 111 and the second outlet 112 is in an open state.

According to the control method of the air conditioner 1000 in the embodiment of the invention, when the water level in the chassis 300 exceeds the first set water level, the water pump body 3 is controlled to be opened to guide the condensed water to the condenser 200 and/or the water tank 400 by using the water distribution device 100, so that the condensed water can be recycled to reduce the temperature of the condenser 200, the heat exchange effect of the condenser 200 can be improved, more energy is saved, the condensed water is evaporated, the evaporation speed of the condensed water is increased, the condensed water can be recycled to the water tank 400 when the amount of the condensed water is large, the service life of the air conditioner 1000 can be prolonged, the situation that the water tank 400 is taken out for pouring when the service life of the air conditioner 1000 is short is avoided, the condensed water does not flow outwards, and the environment is not affected. After the water level in the water tank 400 exceeds the second set water level, the water pump body 3 is controlled to be closed, and the compressor of the air conditioner 1000 is controlled to stop running, so that the evaporator 500 stops producing condensed water, and the fan corresponding to the base plate 300 runs for a set time period, so that the phenomenon of overflowing caused by water fullness can be avoided by evaporating the condensed water in the base plate 300 by the fan.
Further, when the acquired water level in the water tank 400 exceeds the second set water level, the air conditioner 1000 is controlled to send an alarm message (which may be a voice alarm and/or a display message) to prompt the user that the water tank is full, and to prompt the user to treat the condensed water in the water tank 400, for example, to open a plug for draining.

It should be noted that the third set water level may be the same as the second set water level, or the third set water level may be lower than the second set water level.
According to the air conditioner 1000 of the embodiment of the invention, the water level in the water tank 400 is obtained before the air conditioner 1000 is controlled to be started, when the water level in the water tank 400 exceeds the third set water level, the phenomenon that more liquid exists in the water tank 400 or the water tank is full is indicated, and a prompt message is sent to remind a user of treating the water in the water tank 400 first. When the water level in the water tank 400 is lower than the third set water level, it indicates that the water tank 400 can continue to store water, and the air conditioner 1000 is turned on. Thereby avoiding the phenomenon of water overflow when the air conditioner 1000 is started to operate when the water tank 400 has more liquid or is full of water.
In some embodiments of the present invention, the water level in the water tank 400 is detected when the computer is powered on, and if the water tank 400 is detected to be full (i.e., the water level in the water tank 400 exceeds the third set water level), the system is prohibited from operating, and the user is prompted to drain when the water tank is full; if it is detected that the water tank 400 is not full (i.e., the water level in the water tank 400 is lower than the third set water level), the normal power-on operation is performed.
The refrigeration process condensate flows through the condenser 200 and collects on the base pan 300.
When a first water level switch of the chassis 300 detects that the liquid level reaches a first set water level, the water suction pump body 3 is started to operate, condensed water collected on the chassis 300 is sucked into the water inlet area 11 located above the condenser 200 through the water suction pump body 3, the condensed water in the water inlet area 11 can flow to the water distribution area 10, the condensed water in the water distribution area 10 uniformly flows through the condenser 200 through the first water distribution port 101 under the action of gravity, at the moment, the floater 23 does not float upwards, and the water tank channel is closed (namely, the second water channel 13 is closed).
If the condenser 200 cannot completely consume the condensed water, the condensed water flows back to the base plate 300 after flowing through the condenser 200, the water level of the base plate 300 rises, the float 23 is driven to move upwards, the channel of the water tank is opened (i.e. the second water channel 13 is opened), and the condensed water pumped by the suction pump body 3 preferentially enters the water tank 400 to be stored.
When a second water level switch in the water tank 400 detects that the liquid level reaches a second set water level, the compressor is immediately stopped, the fan is turned off in a delayed mode, the system stops running, full water protection is prompted, and a user is reminded to open the plug to drain water.
According to the control method of the air conditioner 1000 in the embodiment of the invention, the condensed water is consumed and processed in the form of water pump circulation and water tank 400 storage, so that overflow is avoided, and meanwhile, the condensed water cools the condenser 200, so that the energy efficiency of the refrigeration system can be improved, and more energy is saved.
