[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1-Figure 6 As shown, the refrigeration device of this embodiment includes a shell 1 and an inner tank 2 and a storage cylinder 3 arranged in the shell 1, the inner tank 2 has a drain port 21 for discharging condensed water to the outside, and a humidity sensor (not shown) is arranged in the storage cylinder 3; the refrigeration device also includes a humidification component 4, and the humidification component 4 includes:

[0027] A water receiving tray 41, used to receive condensed water discharged from the drain port 21;

[0028] The fan 42 is used for blowing air toward the water receiving tray 41 to generate moisture so as to humidify the storage cylinder 2 .

[0029] Specifically, during the refrigeration process of the refrigeration device of this embodiment, condensed water will be formed in the inner tank 2, and the condensed water will be discharged from the drain port 21 to the outside of the inner tank 2, and the humidification component 4 can use the condensed water discharged from the inner tank 2 to humidify the storage barrel 3. Specifically, the water receiving tray 41 in the humidification component 4 can receive and store the condensed water discharged from the drain port 21, and under the action of the fan 42, accelerate the evaporation efficiency of the condensed water in the water receiving tray 41 to form moisture, and the moisture enters the storage barrel 3 to humidify the inside thereof, thereby realizing the automatic humidification of the storage barrel 3 by using condensed water without adding external water. In conjunction with the humidity sensor in the storage barrel 3, when the humidity in the storage barrel 3 is lower than the set value, the fan 42 is started, and the condensed water is received by the water receiving tray 41 and humidified under the action of the fan 42.

[0030] Among them, in order to achieve uniform and efficient humidification inside the storage barrel 3, the humidification component 4 also includes a humidification circulation air duct 43, which is used to transport the moisture formed by the blowing of the fan 42 to the storage barrel 3. Specifically, after the fan 42 blows the condensed water in the docking water tray 41 to form moisture, the moisture will be transported into the storage barrel 3 through the humidification circulation air duct 43, and the return air output by the storage barrel 3 will flow into the humidification circulation air duct 43, thereby realizing the circulation of air in the storage barrel 3 to achieve fast, efficient and uniform humidification. The humidification circulation air duct 43 has an air outlet and a return air outlet, and the air outlet and the return air outlet are respectively connected to the storage barrel 3. Specifically, the moisture enters the storage barrel 3 through the air outlet, and the air in the storage barrel 3 flows back to the humidification circulation air duct 43 through the return air outlet.

[0031] In addition, in order to ensure that the condensed water discharged from the inner tank 2 can flow out smoothly when the humidification treatment is not performed, the bottom of the humidification circulation air duct 43 is also connected to a drain pipe 44, and the water receiving tray 41 is arranged in the humidification circulation air duct 43. The water receiving tray 41 is also used to selectively transport the condensed water discharged from the drain port 21 to the drain pipe 44. Specifically, the water receiving tray 41 can, on the one hand, receive and hold the condensed water during humidification, and on the other hand, can guide the water discharged from the drain port 21 into the drain pipe 44 under non-humidification operation, so that the requirements of effectively collecting condensed water for rapid humidification under humidification operation and smoothly discharging condensed water under non-humidification operation are met. Preferably, the water receiving tray 41 is rotatably arranged in the humidification circulation air duct 43, and the water receiving tray 41 is provided with a water receiving groove 411 for holding condensed water. The water receiving tray 41 is also provided with a drainage channel 412 for transporting condensed water to the drainage pipe 44. Specifically, the water receiving tray 41 can be rotated in the humidification circulation air duct 43 as needed. When humidification treatment is required, the water receiving tray 41 is rotated so that the water receiving groove 411 receives the condensed water discharged from the inner tank 2 to achieve humidification operation. When humidification is not required, the water receiving tray 41 is rotated so that the drainage channel 412 guides the condensed water discharged from the inner tank 2 to flow into the drainage pipe 44. In order to facilitate the automatic rotation control of the water receiving tray 41, a driving mechanism 45 for driving the water receiving tray 41 to rotate is also provided on the humidification circulation air duct 43. The controller of the refrigeration equipment controls the action of the driving mechanism 45 according to the humidity signal detected by the humidity sensor to realize the driving mechanism 45 to rotate the water receiving tray 41 to meet the requirements of humidification or drainage. The driving mechanism 45 can adopt a motor, and the controller can control the forward and reverse rotation of the motor to realize the water receiving tray 41 switching the water receiving trough 411 or the drainage channel 412 to be in the working position.

[0032] Furthermore, the humidification circulation air duct 43 includes a shell 431 and a return air duct 432, the return air duct 432 is connected to the shell 431, the shell 431 is provided with the air outlet, the return air duct 432 is provided with the return air outlet, the fan 42 and the water receiving tray 41 are located in the shell 431, and a water receiving funnel 433 is provided on the top of the shell 431. The water receiving funnel 433 is located at the bottom of the inner tank 2 and covers the drain outlet 21. The water receiving tray 41 is located below the water receiving funnel 433, and the drain pipe 44 is connected to the bottom of the shell. Specifically, during assembly, the shell 431 is installed in the outer shell 1 and is located at the rear of the storage barrel 3. The water collecting funnel 433 on the shell 431 is connected to the drain port 21 at the bottom of the inner tank 2. The condensed water discharged from the inner tank 2 through the drain port 21 enters the shell 431 and is then processed by the water receiving tray 41 to achieve humidification or drainage operations. The shell 431 forms a moisture generating cavity. After the fan 42 is started, the moisture formed by blowing the condensed water in the water receiving groove 411 on the water receiving tray 41 enters the storage barrel 3 through the air outlet on the shell 431. The gas in the storage barrel 3 will flow back to the shell 431 through the return air duct 432 to achieve the circulation of air in the storage barrel 3. Preferably, in order to ensure that the condensed water is discharged smoothly without overflowing into the storage tube 3, the bottom of the shell 431 forms a downwardly recessed concave surface, and a through hole is opened on the concave surface. The drain pipe 44 is connected to the through hole. Specifically, during the drainage process, the condensed water discharged from the inner tank 2 through the drain port 21 is guided to the bottom of the shell 431 through the drainage channel 412 on the water receiving tray 41, and the condensed water is collected on the concave surface at the bottom of the shell 431 and discharged smoothly through the drain pipe 44, wherein the through hole connected to the drain pipe can be set at the bottom of the groove to ensure smooth drainage of the condensed water.

[0033] The present invention also provides a control method for the above-mentioned refrigeration equipment, comprising: when the humidity sensor detects that the humidity value in the storage barrel is lower than a set value, the fan starts to blow air to the condensed water in the docking water tray to form moisture, and the moisture enters the storage barrel to increase the humidity; when the humidity sensor detects that the humidity value in the storage barrel reaches the set value, the fan is turned off.

[0034] Specifically, in the control method of the refrigeration equipment provided by the present invention, during the actual operation of the refrigeration equipment, the humidity sensor in the storage cylinder detects the humidity inside the storage cylinder, and when the humidity is lower than the set value, the humidification component is started to perform humidification treatment. The water receiving tray can collect the condensed water discharged from the inner tank, and realize rapid humidification under the action of the fan. During the humidification treatment, the driving mechanism drives the water receiving tray to rotate so that the water receiving trough and the water receiving funnel are arranged relative to each other to collect the condensed water. At the same time, the fan is started to blow the condensed water in the water receiving tray; when the humidity value in the storage cylinder reaches the requirement, the fan is turned off, and the water receiving tray rotates so that the drainage channel and the water receiving funnel are arranged relative to each other to transport the condensed water to the drain pipe for discharge, and at the same time, the fan is turned off. Preferably, in order to accurately control the humidity and improve the accuracy of humidification, the inclination angle of the water receiving tray and the horizontal plane can be controlled during the humidification process to achieve control of the humidification efficiency, thereby achieving improved humidification accuracy. Specifically, during the humidification process, according to the formula θ=(φ 设定 -φ 当前 )÷φ×90-45, where θ is the inclination angle between the water tray and the horizontal plane, φ 设定 is the humidity value set for the storage cylinder, φ 当前 is the humidity value detected by the humidity sensor, φ is the difference between the maximum humidity and the minimum humidity allowed in the storage cylinder. During the humidification process, the inclination angle of the water receiving tray and the horizontal plane is dynamically adjusted according to the humidity value detected by the humidity sensor, so that the contact area between the condensed water and the wind flow is different to obtain different humidification efficiencies. When the difference between the set humidity value and the actual humidity value is large, the water receiving groove of the water receiving tray is tilted and faces the fan to increase the contact area between the condensed water and the wind flow, thereby accelerating the humidification speed. When the set humidity value and the actual humidity value gradually approach each other, the water receiving tray gradually rotates to a horizontal level and continues to rotate away from the fan to reduce the contact area between the condensed water and the wind flow, thereby slowing down the humidification speed, and finally obtaining an accurate humidity value.

[0035] Compared with the prior art, the advantages and positive effects of the present invention are: by adding a humidifying component, the water receiving tray in the humidifying component can hold the condensed water discharged from the inner tank, and under the action of the fan, the evaporation rate of the condensed water in the water receiving tray is accelerated to form moisture, and the moisture enters the storage cylinder to realize humidification and adjustment of the internal humidity. Since the user does not need to add water and humidify from the outside, the condensed water discharged from the inner tank is used for automatic humidification operation, which improves the convenience of use and user experience.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
