[0027] Reference Figure 1-3 This embodiment discloses a constant humidity system for a refrigeration device. The refrigeration device includes a cabinet 10 having a storage room 20 and a controller installed on the cabinet 10. The constant humidity system includes:

[0028] A humidifying box 30 is installed on the cabinet 10. The humidifying box 30 is provided with an air inlet 31 and an air outlet 32 ​​communicating with the interior of the storage chamber 20. A fan 40 is provided in the humidifying box 30 at a position corresponding to the air outlet 32.

[0029] A water storage chamber 33 is provided at the lower end of the humidifying box 30, and the humidifying paper 50 is arranged at the air inlet 31 and immersed in the water in the water storage chamber 33.

[0030] The humidity detection probe 60 is installed on the cabinet 10 and is used to detect the humidity in the storage room 20. The humidity detection probe 60 and the fan 40 are electrically connected to the controller respectively.

[0031] The humidity detection probe 60 is used to detect the humidity in the storage chamber 20. When the humidity in the storage chamber 20 is lower than the preset humidity, the fan 40 starts and blows air into the storage chamber 20 for humidification, thereby ensuring that the humidity in the storage chamber 20 is constant to meet the storage humidity requirements of different goods in the storage chamber 20.

[0032] In response to the above technical solution, the present application provides a water filling box 70 on the outer wall of the cabinet 10, and the water filling box 70 is provided with a water filling port 71. The water filling box 70 is distributed above the water storage chamber 33 and is connected to the water storage chamber 33 in the humidification box 30 through a water pipe.

[0033] Since a certain water level needs to be maintained in the water storage chamber 33 so that the humidification paper 50 is sufficiently moistened, a water injection box 70 is provided on the outer wall of the cabinet 10. The water injection box 70 is distributed above the water storage chamber 33 and communicates with the water storage chamber 33 in the humidification box 30 through a water pipe. Figure 1 As shown, the water filling box 70 is arranged on the top of the cabinet 10 and is connected to the inside of the water storage chamber 33 through a hose. After water is filled into the water filling box 70, the water will flow into the water storage chamber 33 through the hose to ensure that the humidification paper 50 is immersed in water.

[0034] The water inlet 71 is provided with a detachable sealing cover 72 to facilitate water injection and prevent dust from falling into the sealing cover 72 and causing water pollution.

[0035] Furthermore, a water baffle 34 is provided at the lower end of the humidification box 30 , one side of the water baffle 34 and the inner wall of the humidification box 30 enclose the water storage cavity 33 , and an overflow hole 36 is provided at the lower end of the humidification box 30 on the other side of the water baffle 34 .

[0036] When the fan 40 starts to blow air into the storage chamber 20, the wind blown into the storage chamber 20 by the fan 40 carries moisture for humidification through the humidification paper 50. Therefore, it is necessary to ensure that there is a certain water level in the humidification box 30 to avoid immersing the humidification paper 50 and the fan 40 in water. By setting a water baffle 34 in the humidification box 30, when the water level exceeds the water baffle 34, the water will overflow the water baffle 34 and be discharged from the overflow hole 36.

[0037] The upper waste water box 80 is open at the upper end and is disposed below the humidification box 30 , so that water escaping from the overflow hole 36 in the humidification box 30 can flow into the upper waste water box 80 under the action of gravity.

[0038] In this embodiment, a condenser 100 is provided on the cabinet 10, and the humidification box 30 is arranged below the condenser 100. A water receiving groove 37 is provided at the upper end of the humidification box 30, and a water drop hole 38 is provided in the water receiving groove 37. The water drop hole 38 is connected to the inside of the water storage chamber 33 to collect the condensed water generated by the condenser 100.

[0039] In order to facilitate the collection of overflow water, a lower waste water box 90 is also included. An inspection compartment 11 is provided on the cabinet 10. The lower waste water box 90 is arranged in the inspection compartment 11 and is located below the upper waste water box 80. A drain hole 81 is provided at the bottom of the upper waste water box 80. The drain hole 81 is connected to the lower waste water box 90, so that the overflow water in the cabinet 10 and the condensed water generated by the condenser 100 can be collected into the lower waste water box 90 through the upper waste water box 80, so as to facilitate the treatment of accumulated water.

[0040] In the present application, at least two storage chambers 20 are provided on the cabinet 10 , each of the storage chambers 20 is provided with a humidity detection probe 60 , and the cabinet 10 is provided with a humidification box 30 corresponding to each storage chamber 20 .

[0041] The controller controls the operation of the corresponding fans 40 by detecting the humidity in different storage chambers 20. As shown in the drawings, the humidification boxes 30 corresponding to the storage chambers 20 at different levels are connected in sequence from top to bottom.

[0042] As described with reference to the drawings, the humidification boxes 30 are horizontally staggered so that the overflow holes 36 of the humidification boxes 30 are horizontally staggered, and the water in the overflow cavity 35 in each humidification box 30 can fall into the upper waste water box 80 .

[0043] Of course, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
