[0002] At present, humidifiers and dehumidifiers are two independent products on the market. Users need to buy two products for wet and dry weather. Not only does it cost more money, it also takes up a lot of space at home, and the daily cleaning workload will also increase. In response to the above problems, the prior art also installs a humidifier and a dehumidifier in one machine. The humidification and dehumidification functions are realized by their respective mechanisms. Humidification mainly includes fog humidification and fogless humidification.

Due to the combination of humidification and dehumidification, the body structure is complex and the volume is relatively large. Therefore, in order to avoid the shortcomings existing in the prior art, it is necessary to improve the prior art. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figure 1 The utility model is shown as a humidifying and dehumidifying machine, comprising a casing, a compressor 1 installed in the casing, a condenser 2, an evaporator 3, a fan assembly 4, a water tank, a four-way valve 5 and a water sprinkling assembly 6, the four-way valve 5 being respectively connected to the compressor 1, the condenser 2 and the evaporator 3, the water sprinkling assembly 6 comprising a water pump, a spray head, a water outlet pipe respectively connected to the water pump and the spray head, and a water inlet pipe respectively connected to the water pump and the water tank, the spray head being arranged above the condenser 2 and the evaporator 3, and the water tank being arranged below the condenser 2 and the evaporator 3.

[0018] The evaporator 3 and the condenser 2 are respectively provided with fins, and the spray head is arranged above the fins.

[0019] A controller is provided on the casing, and the controller is electrically connected to the compressor 1, the condenser 2, the evaporator 3, the fan assembly 4, the four-way valve 5 and the water sprinkling assembly 6 respectively.

[0020] A humidity sensor is arranged outside the casing, a water level sensor and a temperature sensor are arranged in the water tank, and the humidity sensor, the water level sensor and the temperature sensor are electrically connected to the controller respectively.

[0021] An air inlet is provided on one side of the casing, and a filter is provided inside the air inlet.

[0022] The fan assembly 4 includes a fan, an air duct and an air outlet opened at the upper end of the casing. The fan is arranged on the opposite side of the air inlet, the inlet of the air duct is connected to the fan, and the outlet of the air duct is connected to the air outlet.

[0023] Universal wheels 7 are provided at the bottom of the casing.

[0024] Here’s how it works:

[0025] 1. Dehumidification internal cycle: When compressor 1 is running, compressor 1 sends high-temperature and high-pressure gas into condenser 2 through four-way valve 5 for cooling, so that the gas becomes low-temperature and high-pressure gas, and then becomes low-temperature and low-pressure liquid through capillary interception and filtration, and then evaporates and absorbs heat through evaporator 3, and finally returns to compressor 1 to become low-temperature and low-pressure gas. This cycle repeats.

[0026] 2. Dehumidification external circulation: Through the operation of the fan, the humid air is sucked in from the air inlet, and the water vapor in the air is condensed into water through the evaporator 3 and adsorbed on the fins. The humid air becomes dry air and is discharged from the air outlet.

[0027] 3. Humidification principle: When compressor 1 is running, compressor 1 passes high-temperature and high-pressure gas into evaporator 3 through four-way valve 5, then enters condenser 2 through capillary interception and filtration, and finally returns to compressor 1. When the high-temperature and high-pressure gas generated by compressor 1 passes through evaporator 3, water spraying component 6 controls water to spray from the top of evaporator 3 and condenser 2. When water flows through evaporator 3, it will increase the temperature of water through heat exchange, which will accelerate the volatilization of water. Part of the water vapor will directly volatilize into the room to realize the humidification function; when water sprays through condenser 2, it helps condenser 2 to cool down and reduce the pressure of refrigerant. At the same time, the water in condenser 2 also plays the role of humidifying air. These humidified air is sent to the room through the fan to realize the humidification function. Evaporator 3 and condenser 2 play the role of heat exchange and the role of humidifying cotton in traditional household humidifiers. By controlling the amount of water sprayed on evaporator 3 and condenser 2, as well as the temperature and program settings of the performance system, compressor 1 can be realized to work continuously or intermittently or not. When the compressor 1 is not working, the evaporator 3 and the condenser 2 replace the humidifying cotton of the traditional household humidifier. Since the offset of the fins of the evaporator 3 and the condenser 2 is small but can guide the water well, when the water flows through the surface of these fins, the water will cover the surface of the fins. When the air flows through the surface of these fins under the action of the fan, the humidity of the air will also increase. When the air with high humidity is sent to the room through the fan, it plays a humidifying role.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
