Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0042] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplicity, the elements and settings of particular examples in the following description are shown in great detail. Of course, they are merely examples and are presented to provide an enabling description of the application. Also, the present application can repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and / or settings discussed.

[0043] In order to facilitate the description, spatial relative terms can be used in the description to describe the relative position relationship or movement condition of one element or feature with respect to another element or feature as shown in the drawings, such as "inner", "outer", "inboard", "outboard", "under", "below", "on", "above", "front", "back", and the like. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is flipped over or the posture is changed or the movement state is changed, then the directional indications will also change accordingly, for example: the element described as "under" or "below" another element or feature will be oriented as "above" or "above" another element or feature. Therefore, the example term "below" can include both up and down orientations. The device can be additionally oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the description are interpreted accordingly.

[0044] In order to solve the technical problem of single function of the dehumidifier in the prior art, the application provides a dehumidifier which can have both dehumidification function and humidification function, and specifically as follows.

[0045] Figures 1 to 6 A dehumidifier provided by the application includes a box body 1, an evaporator 2, a condenser 3, a water spraying pipeline 4 and a water tank 5. The box body 1 has an installation cavity 11 inside; the evaporator 2 is arranged in the installation cavity 11 and used for absorbing heat in humid air to cool the air and condense water vapor in the air into water droplets; the condenser 3 is arranged in the installation cavity 11 and used for changing refrigerant from gas state back to liquid state to release heat, heat air, and then discharge to keep indoor temperature stable; the evaporator 2 and the condenser 3 work cooperatively to achieve dehumidification effect; the condenser 3 is arranged at intervals from the evaporator 2, and the water spraying pipeline 4 is arranged between the condenser 3 and the evaporator 2; the water spraying pipeline 4 is provided with water spraying holes 41 which can spray water in the water spraying pipeline 4 to fins of the evaporator 2 and the condenser 3 to increase indoor humidity through water vapor evaporation and air flow; the water tank 5 is arranged in the installation cavity 11 and communicates with the water spraying pipeline 4 through a water pipe 51, and the water tank 5 is used for loading cooled water vapor in the dehumidification function and providing water vapor loaded and transmitted to the water spraying pipeline 4 in the humidification function.

[0046] In the embodiment, the dehumidifier includes the box body 1 which has the installation cavity 11 for installing the remaining components, the evaporator 2 and the condenser 3 which are arranged in the installation cavity 11 and used for performing heat exchange to dehumidify, and the water spraying pipeline 4 which is arranged between the evaporator 2 and the condenser 3 and communicates with the water tank 5. During dehumidification, water vapor in air forms water droplets through the evaporator 2 to reduce humidity of the discharged air; during humidification, water in the water tank 5 is pumped to the water spraying pipeline 4 and sprayed to the evaporator 2 and the condenser 3 through the water spraying holes 41, and air passing through the evaporator 2 and the condenser 3 will take away water to increase humidity of the discharged air.

[0047] As Figures 1-5As shown in the technical scheme of the embodiment, both ends of the water spraying pipeline 4 are connected with side plates 42, each of which is fixedly connected with the box body 1, and a water spraying pipe interface 43 is formed in one of the side plates 42, which is communicated with the water spraying pipeline 4, and a water pipe 51 is connected with the water spraying pipe interface 43. Preferably, the side plates 42 are arranged in the same manner as and parallel to the evaporator 2 and the condenser 3, and a plurality of water spraying pipelines 4 can be arranged along the side plates 42, which can spray water simultaneously to improve the humidifying efficiency. Further, a plurality of water spraying holes 41 can be arranged along the water spraying pipeline 4, and two rows of the water spraying holes 41 are formed, one row of the water spraying holes 41 is formed at an upward angle of 45° with respect to the water spraying pipeline 4 in the direction opposite to the evaporator 2, and the other row of the water spraying holes 41 is formed at an upward angle of 45° with respect to the water spraying pipeline 4 in the direction opposite to the condenser 3. In this way, the water in the water spraying pipeline 4 can be sprayed upward at an angle of 45° with respect to the evaporator 2 and the condenser 3, and the water can be evenly distributed on the fins of the evaporator 2 and the condenser 3 in the form of mist under the action of gravity. According to the law of maximum range of projectile, the horizontal range is the largest when the projection angle is 45° under the same initial speed. Therefore, the water in the water spraying pipeline 4 can be sprayed to the far end of the fins when the water is sprayed upward at an angle of 45° with respect to the evaporator 2 and the condenser 3.

[0048] As Figures 2-6 shown in the technical scheme of the embodiment, one side of the water tank 5 is provided with a water pump 52, the input end of the water pump 52 is communicated with the water tank 5 through a water suction pipe 57, one end of a water pipe 51 is connected with the output end of the water pump 52, and the other end of the water pipe 51 is communicated with the water spraying pipeline 4, and the water pipe 51 is provided with a first electromagnetic valve 53.

[0049] The water tank 5 is filled with water, when humidification is needed, the first electromagnetic valve 53 is opened, and the water pump 52 is started to pump the water in the water tank 5 out, which enters the water spraying pipeline 4 through the first electromagnetic valve 53, and is sprayed out through the water spraying holes 41. This structure is compact and low in cost.

[0050] As Figures 2-6 shown in the technical scheme of the embodiment, the box body 1 is provided with a water outlet 17, the water pipe 51 between the water pump 52 and the first electromagnetic valve 53 is connected with a water drainage pipeline 54 through a three-way valve 58, the water drainage pipeline 54 is communicated with the water outlet 17, and the water drainage pipeline 54 is provided with a second electromagnetic valve 55.

[0051] When dehumidifying, the water vapor in the humid air is cooled and attached to the evaporator 2 after passing through the evaporator 2, and then is discharged into the water tank 5. When the water in the water tank 5 is full, the water pump 52 is opened, the first electromagnetic valve 53 is closed, and the second electromagnetic valve 55 is opened. The water pump 52 pumps the water in the water tank 5 out, through the three-way valve 58 into the drain pipe 54, and out of the box body 1 through the drain port 17 after passing through the second electromagnetic valve 55. Preferably, a water level sensor can be arranged in the water tank 5 to monitor the water level in the water tank 5 and preset an alarm value. When the water level in the water tank 5 reaches the alarm value, the water level sensor automatically opens the water pump 52 to pump the water in the water tank 5 out. This method can reduce labor costs and achieve automation.

[0052] As shown in Figure 2 , 4 , in the technical solution of the embodiment, the installation cavity 11 is provided with a water receiving tray 6, the evaporator 2 and the condenser 3 are installed above the water receiving tray 6, and the water tank 5 is arranged below the water receiving tray 6. The water tank 5 is provided with a water inlet 56 above it, the water receiving tray 6 is provided with a water leakage port, the water leakage port is aligned with the water inlet 56, the water receiving tray 6 is provided with a plurality of insertion slots above it, and the side plate 42, the evaporator 2 and the condenser 3 are inserted into the insertion slots.

[0053] When dehumidifying, the water vapor in the humid air is cooled and attached to the evaporator 2 after passing through the evaporator 2, and then is discharged into the water tank 5. When the water in the water tank 5 is full, the water pump 52 is opened, the first electromagnetic valve 53 is closed, and the second electromagnetic valve 55 is opened. The water pump 52 pumps the water in the water tank 5 out, through the three-way valve 58 into the drain pipe 54, and out of the box body 1 through the drain port 17 after passing through the second electromagnetic valve 55. Preferably, a water level sensor can be arranged in the water tank 5 to monitor the water level in the water tank 5 and preset an alarm value. When the water level in the water tank 5 reaches the alarm value, the water level sensor automatically opens the water pump 52 to pump the water in the water tank 5 out. This method can reduce labor costs and achieve automation.

[0054] As shown in Figures 2-6 , in the technical solution of the embodiment, the installation cavity 11 is provided with a middle seat 12, the water tank 5 is installed in the middle seat 12, the water receiving tray 6 is arranged above the middle seat 12, and a water guide hole is formed above the middle seat 12 and aligned with the water inlet 56.

[0055] The middle seat 12 is used for installing the water tank 5 and providing positioning of the water receiving tray 6 during installation. The water guide hole is obliquely arranged along the radial direction of the water inlet 56 to increase the water inlet range of the water inlet 56 and prevent the water dripping from the water leakage hole from falling outside the water tank 5.

[0056] As shown in Figure 1 , 4 , in the technical solution of the embodiment, the box body 1 is provided with an air inlet 13 and an air outlet 14. The air inlet 13 is arranged on the side of the evaporator 2 away from the condenser 3, and the air outlet 14 is arranged at the upper end of the box body 1.

[0057] During dehumidification, humidified air enters the housing 1 through the air inlet 13. As the air passes through the evaporator 2, the water vapor on the air condenses upon contact with the condenser and adheres to the fins of the evaporator 2. It then falls into the water collection tray 6 below due to gravity, thus entering the water tank 5. After passing through the evaporator 2, the air enters the condenser 3, where it is heated to the temperature outside the housing 1. Because hot air is less dense than cold air, the heated air is discharged from the air outlet 14 at the top. During humidification, the water spray pipe 4 sprays water from the water tank 5 onto the fins of the evaporator 2 and condenser 3. The condenser 3 heats the water, causing it to turn into water vapor. Air entering through the air inlet 13 passes through the evaporator 2 and condenser 3, carrying the water vapor, and is discharged from the air outlet 14, thus increasing the humidity of the air outside the housing 1. This setup helps improve airflow efficiency, avoids airflow obstruction by ground obstacles, saves space, reduces noise, and provides more even air distribution, improving user comfort.

[0058] A fan assembly 7 is provided inside the mounting cavity 11. The fan assembly 7 includes a bracket 71, a blower 72, a motor mounting base 73, and a motor 74. The bracket 71 is installed on the cavity wall of the mounting cavity 11. The bracket 71 has a mounting hole 711. The blower 72 is installed in the mounting hole 711. The motor mounting base 73 is installed at the end of the blower 72 away from the bracket 71. The motor 74 is installed at the end of the motor mounting base 73 away from the blower 72. The motor mounting base 73 has a through hole 731. The output end of the motor 74 passes through the through hole 731 and connects to the blower 72.

[0059] During operation, the motor 74 starts and drives the blower 72 to rotate, expelling the air inside the housing 1 to create negative pressure. Then, external air enters the housing 1 through the air inlet 13 and passes through the condenser 3 and evaporator 2 before being discharged outdoors. Preferably, the air intake device and the air inlet 13 are symmetrically arranged on the front and rear sides of the housing 1. This arrangement ensures a uniform airflow velocity as the air passes through the evaporator 2 and condenser 3 from the air inlet 13, guaranteeing effective humidification / dehumidification.

[0060] like Figures 2-6 As shown, in the technical solution of this embodiment, a compressor 15 is also provided in the mounting cavity 11. The compressor 15 is connected to the condenser 3 by a circulation pipe 16. The circulation pipe 16 is filled with refrigerant. The refrigerant is compressed into a high-temperature and high-pressure gas by the compressor 15. After passing through the condenser 3, the refrigerant releases heat and is converted into liquid refrigerant. The released heat is dissipated into the air through the fins, thereby heating the air. The condenser 3 is also connected to the evaporator 2 by a circulation pipe 16. The liquid refrigerant flows from the condenser 3 into the evaporator 2 and absorbs heat from the air through the fins of the evaporator 2 to remove water vapor from the air during dehumidification and evaporate back into gaseous refrigerant. The evaporator 2 is connected to the compressor 15 by a circulation pipe 16. The gaseous refrigerant in the evaporator 2 returns to the compressor 15 to complete the cycle.

[0061] As Figure 1 shown, in the technical solution of the embodiment, the bottom of the box 1 is provided with universal wheels 8 to facilitate the movement of the device. The universal wheels 8 have the advantage of 360-degree omnidirectional rotation design, which enables the object to be easily moved and turned in any direction without the need to adjust the angle or change the position, greatly improving flexibility and convenience.

[0062] As Figure 1 shown, in the technical solution of the embodiment, the two sides of the box 1 are provided with grabbing parts 9 for picking up the dehumidifier or pushing the dehumidifier to move with the universal wheels 8. The embodiment adopts the method of forming the grabbing part 9 by opening a hole in the side of the box 1, which can reduce the weight and volume.
