In this application embodiment, carry out the moisturizing for moisturizing water tank 11 in the follow external water source through the branch road of intaking, during water in the moisturizing water tank 11 flows to heating water tank 12 through the branch road of intaking, the humidification load heats the vaporization to heating water tank 12's water to realize the humidification function. Alternatively, the external water source refers to a water source outside the humidifier, and may be, for example, a faucet, water poured manually, or a liquid generated by the air conditioner during heat exchange when used in combination with the air conditioner, and is not limited in particular. When water is added to the water supplementing water tank 11 and the heating water tank 12, a fixed time for water supplementing may be set, for example, a switch may be set at one end of the water inlet branch, and the switch is controlled by the control unit to turn on the water supplementing water tank 11 and the heating water tank 12 at every preset time interval; in addition, in order to reduce the occurrence of the overflow of the water replenishing tank 11 and the water heating tank 12, the water level detection based on the principle that the maximum water level in the water heating tank 12 and the maximum water level in the water replenishing tank 11 coincide with each other, that is, the closing control of the switch can be performed. It should be noted that, in other embodiments, the split type water replenishing water tank 11 and the split type heating water tank 12 may not be provided, an integrated water tank may be provided, the integrated water tank is replenished with water through the water inlet branch, and then the water in the integrated water tank is heated and vaporized through the humidification load, which is not particularly limited.

Optionally, the humidifying load includes, but is not limited to, an electric bar or the like that can warm the water.
In the embodiment of the present application, the refrigerant branch 2 has an inlet a and an outlet b. Optionally, the inlet a is used for being connected with the output end c of the condenser 5, and the refrigerant (high-temperature and high-pressure liquid) output by the output end c of the condenser 5 can enter the inlet a; the outlet b is used for being connected with the input end d of the evaporator 6 and outputting the refrigerant flowing through the refrigerant branch 2 to the input end d of the evaporator 6. It should be noted that the refrigerant branch 2 is disposed outside the water storage container 1 and contacts the water replenishing water tank 11 and the heating water tank 12, so that when the refrigerant flows through the refrigerant branch 2, the high-temperature and high-pressure refrigerant can transfer heat to the water replenishing water tank 11 and the heating water tank 12, so that the temperature of the water in the water replenishing water tank 11 and the heating water tank 12 is increased, which is beneficial to reducing the condition that the water in the water replenishing water tank 11 and the heating water tank 12 is frozen to become solid, and the humidification load cannot realize the humidification function. Specifically, when the refrigerant in the high-temperature and high-pressure liquid state is output from the output end c of the condenser 5, enters the inlet a and flows through the refrigerant branch 2, the water in the water replenishing water tank 11 is heated by the water replenishing water tank 11 in the flowing process of the refrigerant, then the refrigerant flows through the heating water tank 12 to heat the water in the heating water tank 12, and then flows to the input end d of the evaporator 6 through the outlet b. It should be noted that when the refrigerant flows through the refrigerant branch 2, the refrigerant may also first pass through the heating water tank 12 to heat the water in the heating water tank 12, then pass through the water replenishing water tank 11 to heat the water in the water replenishing water tank 11, and then flow from the outlet b to the input end d of the evaporator 6; or, the refrigerant branch may be set to heat the water in the heating water tank 12 and the water replenishing water tank 11 simultaneously when the refrigerant flows through the refrigerant branch 2, and then the heated water flows from the outlet b to the input end d of the evaporator 6, which is not limited specifically.

Specifically, the control unit controls the closing and the conduction of the first valve 3, so as to control whether the refrigerant output from the output end c of the condenser 5 can flow through the refrigerant branch 2 to heat the water in the refill water tank 11 and the heating water tank 12, for example: when the first valve 3 is in the on state, the refrigerant output from the output end c of the condenser 5 can flow through the refrigerant branch 2 through the inlet a to heat the water in the water replenishing water tank 11 and the heating water tank 12, and conversely, when the first valve 3 is in the off state, the refrigerant cannot flow through the refrigerant branch 2 to heat the water in the water replenishing water tank 11 and the heating water tank 12. Optionally, the first valve 3 includes, but is not limited to, a solenoid valve, an electric butterfly valve, an electric ball valve, or the like.
In this embodiment, the second valve 4 is disposed between the outlet b of the refrigerant branch 2 and the input end d of the evaporator 6, and is configured to realize one-way flow from the refrigerant to the evaporator 6, that is, the refrigerant can only flow out from the outlet b, and then flows to the input end d of the evaporator 6 in one-way. Optionally, the second valve 4 may be a one-way valve, and the refrigerant is conducted from the outlet b of the refrigerant branch 2 to the input end d of the evaporator 6 in a one-way manner, that is, the refrigerant can only flow from the outlet b to the input end d of the evaporator 6; alternatively, in other embodiments, the second valve 4 may also be an electromagnetic valve, an electric butterfly valve, an electric ball valve, or the like, and the control unit controls the second valve 4 to be turned on when the refrigerant enters the inlet a and flows through the refrigerant branch 2, and otherwise controls the second valve 4 to be turned off, so as to prevent the refrigerant from flowing in the refrigerant branch 2 through the outlet b from the input end d of the evaporator 6.
In the embodiment of the present application, the detection unit is configured to obtain an inlet temperature at an inlet a of the refrigerant branch 2 and a water temperature in the water reservoir 1 (i.e., a temperature of water in the water reservoir 1). Alternatively, the sensing unit includes a first temperature sensor T1, a second temperature sensor T2, and a third temperature sensor T3. The first temperature sensor T1 is disposed at an inlet a of the refrigerant branch 2, for example, at the inlet a or within a preset range from the inlet a, and is configured to obtain an inlet temperature Tr, for example, including but not limited to, within 10cm from the inlet a; the second temperature sensor T2 is disposed on the water replenishing tank 11 and configured to obtain a third temperature Tb of the water replenishing tank 11, that is, the temperature of water in the water replenishing tank 11; the third temperature Tb sensor T3 is provided to the heating water tank 12 for acquiring a fourth temperature Tj of the heating water tank 12, i.e., the temperature of the water in the heating water tank 12. Alternatively, the second temperature sensor T2 may be disposed on the outer wall of the refill water tank 11 to indirectly obtain the temperature of the water in the refill water tank 11, or the inner wall of the refill water tank 11 to obtain the temperature of the water in the refill water tank 11 to obtain a more accurate temperature, and the second temperature sensor T2 may be protected by a waterproof material when disposed on the inner wall of the refill water tank 11. Similarly, the third temperature sensor T3 may be disposed on the outer wall of the heating water tank 12 to indirectly obtain the temperature of the water in the heating water tank 12, or disposed on the inner wall of the heating water tank 12 to obtain the temperature of the water in the heating water tank 12 to obtain a more accurate temperature, or the third temperature sensor T3 may be protected by a waterproof material.
In the embodiment of the present invention, the water temperature includes the third temperature Tb and the fourth temperature Tj, and when the subsequent temperature determination is performed, the third temperature Tb and the fourth temperature Tj need to be considered when the water temperature is taken as a determination factor. It will be appreciated that when the reservoir 1 is an integral tank in some embodiments, the temperature of the water is the temperature of the water in the integral tank.
In this embodiment of the application, the control unit is a main control unit of the humidifier, and the control unit is connected to the first temperature sensor T1, the second temperature sensor T2, the third temperature sensor T3, the first valve 3, and the humidification load, and is configured to process data of the first temperature sensor T1, the second temperature sensor T2, and the third temperature sensor T3, that is, process the inlet temperature Tr, the third temperature Tb, and the fourth temperature Tj, and control the operating states of the first valve 3 and the humidification load according to a processing result, so as to control the operating state of the humidifier to be on or off. Specifically, when the water temperature is less than the first temperature and the inlet temperature Tr is greater than the second temperature, optionally, when the third temperature Tb or the fourth temperature Tj is less than the first temperature, and the inlet temperature Tr is greater than the second temperature, the first valve 3 is controlled to be in the on state, so that the refrigerant enters the inlet a from the output end c of the condenser 5. It should be noted that in the embodiment of the present application, a part of the refrigerant (high-temperature and high-pressure liquid) flowing out of the output end c of the condenser 5 enters the inlet a, and another part of the refrigerant flows into the evaporator 6, so that the evaporator 6 can normally operate, and in other embodiments, the refrigerant (high-temperature and high-pressure liquid) flowing out of the output end c of the condenser 5 may completely enter the inlet a, so as to improve the heating effect on the water in the water replenishing water tank 11 and the heating water tank 12, that is, in the embodiment of the present application, at least a part of the refrigerant is controlled to enter the inlet a. Then, when a part of the refrigerant (high-temperature and high-pressure liquid) enters the inlet a, the refrigerant flows through the refrigerant branch 2 to transfer heat of the refrigerant to the water in the makeup water tank 11 and the heating water tank 12, so that the water in the makeup water tank 11 and the heating water tank 12 is heated.

When at least one of the third temperature Tb or the fourth temperature Tj is lower than the first temperature, that is, it indicates that the refill water tank 11 and the heating water tank 12 need to be heated, water in the refill water tank 11 and the heating water tank 12 may be frozen or may be frozen, and when the inlet temperature Tr is higher than the second temperature, the first valve 3 is controlled to be in a conducting state, so that a portion of the refrigerant enters the inlet a and flows through the refrigerant branch 2, thereby heating the water in the refill water tank 11 and the heating water tank 12, and flows through the outlet b and the second valve 4 to enter the input end d of the evaporator 6 after being heated, while another portion of the refrigerant also reaches the input end d of the evaporator 6 after passing through the first throttling component 9, and the refrigerant absorbs heat in the evaporator 6 and then is output from the output end of the evaporator 6 through the four-way valve 8 to return to the input end of the compressor 7. It should be noted that when the third temperature Tb and the fourth temperature Tj gradually increase until both the third temperature Tb and the fourth temperature Tj are greater than or equal to the first temperature, the humidification load is controlled to start, and the humidification load is switched to start, so as to heat and vaporize the water in the heating water tank 12 to achieve the humidification function.

As shown in fig. 3, when the air conditioner is in the cooling mode, the indoor heat exchanger 5 'is an evaporator, the outdoor heat exchanger 6' is a condenser, and the flow paths of the refrigerant are: compressor 7 → four-way valve 8 → outdoor heat exchanger 6 '→ first throttling part 9 → indoor heat exchanger 5' → four-way valve 8 → compressor 7.

Specifically, the indoor units of the two multi-split air conditioners are a first indoor unit 51 and a second indoor unit. It should be noted that the specific structure and connection relationship of the second indoor unit are similar to those of the condenser 5 described above, and therefore the second indoor unit is described as the condenser 5. In the embodiment of the present invention, the inlet a is connected to the output end of the first indoor unit 51, the inlet end of the condenser 5 is connected to the input end of the first indoor unit 51, the first electronic expansion valve 10A is disposed between the output end of the condenser 5 and the inlet a, the second electronic expansion valve is disposed between the output end of the first indoor unit 51 and the inlet a, the second throttling component 10C is disposed between the input end of the first indoor unit 51 and the four-way valve 8, the third throttling component 10D is disposed between the input end of the evaporator 6 and the output end of the first indoor unit 51, and the fourth throttling component 10E is disposed between the output end of the condenser 5 and the inlet a.

It should be noted that the value of the second temperature is greater than the value of the first temperature, for example, the second temperature includes but is not limited to 20 ℃, and the first temperature includes but is not limited to 2 ℃. Specifically, the first temperature and the second temperature are set according to the size relationship, so that when the temperatures of the water in the water replenishing water tank 11 and the water in the heating water tank 12 need to be heated, the refrigerant entering from the inlet a can provide a function of heating the water in the water replenishing water tank 11 and the water in the heating water tank 12, and the realization of a subsequent humidifying function is facilitated.
