When the wine storage device works specifically, the compressor controls the evaporator 500 to operate to refrigerate, a large amount of condensed water is condensed on the surface of the evaporator 500, so that the humidity in the wine storage cavity 151 is reduced, the controller controls the air supply device 700 to suck air flow from the wine storage cavity 151 through the air inlet 310 and blow the sucked air flow to the evaporator 500, a part of the air flow blown to the evaporator 500 passes through the first flow passage 330 formed between the air duct cover plate 200 and the evaporator 500, a part of the air flow flowing through the first flow passage 330 is discharged from the multiple rows of air discharge holes 321 at different positions, the air discharge holes 321 are sequentially arranged along the height direction of the air duct cover plate 200, so that the air flow discharged through the air discharge holes 321 at a high position during circulation partially flows through the partial area of the first side surface 510 of the evaporator 500 to take away water vapor on the partial area of the evaporator 500 and blow the water vapor to different height positions of the wine storage cavity 151, refrigeration and humidification of different positions of the wine storage cavity 151 are realized to make up for the loss of water vapor in the wine storage cavity 151; a part of the air flow is discharged to the wine storage chamber 151 through the air outlet 321 in the lower region, and the part of the air flow completely flows through the first side surface 510 of the evaporator 500, takes away a large amount of water vapor on the first side surface 510 of the evaporator 500, and is blown into the wine storage chamber 151, so that the humidity in the wine storage chamber 151 is compensated.

Another portion of the air flow blowing toward the evaporator 500 will flow through the second flow channel 340 and out, and due to the shielding and guiding of the evaporator 500, this portion of the air flow will pass completely through the second side 520 of the evaporator 500, carrying away a large amount of water vapor on the second side 520 of the evaporator 500. There is also a water storage element 600 at the bottom of the evaporator 500, and there is a gap between the water storage element 600 and the bottom of the evaporator 500, and this part of the air flow will flow through the water storage element 600, sweep the water surface of the water storage element 600, carry away a large amount of water vapor in the water storage element 600, and finally join with the air flow with water vapor flowing from the first flow channel 330 to the bottom position to be discharged from the air discharge hole 321 at the bottom, so as to humidify the wine storage chamber 151.

Preferably, in the present embodiment, the evaporator 500 is a plate-shaped blow-up evaporator 500, and the plate-shaped blow-up evaporator 500 can be fixed to the inner container by screws. Adopt plate-like evaporimeter 500 to have great heat transfer area, when setting up, can make evaporimeter 500 extend to the position that is close to water storage element 600 from air intake 310 bottom, ensure that evaporimeter 500 has enough big heat transfer area, and then make the evaporimeter 500 area that can be used to condense the comdenstion water also grow, then can make the quantitative of condensing the comdenstion water on evaporimeter 500 surface grow like this, the quantitative of the vapor that can be used to take away grows, make whole evaporimeter 500 not only refrigerate effectually but also the humidification effect also grow.

In this embodiment, the air flow in the wine storage chamber 151 enters from the air inlet 310, is pressurized by the air blowing device 700, is blown to the evaporator 500, and is discharged from the air outlet 320. The air flow velocity is increased after the air flow is pressurized and acted by the air supply device 700, when the air flow passes through the evaporator 500, the condensed water on the surface of the evaporator 500 can be taken away, and a large amount of water vapor can be taken away from the water storage element 600, meanwhile, because the air flow sucked from the wine storage cavity 151 can rapidly flow through the side surface of the evaporator 500 under the pressurization effect of the air supply device 700, only a small amount of water vapor contained in the air flow can be condensed on the side surface of the evaporator 500 when the air flow passes through the evaporator 500, the humidity loss of the air flow sucked from the wine storage cavity 151 is reduced, and the humidity of the air flow blown to the wine storage cavity 151 is ensured to be constant.

Furthermore, because the air current can pass through two sides of the evaporator 500 in the embodiment, the contact area of the air current and the condensed water on the evaporator 500 is enlarged due to the contact of the two sides, the humidification area of the evaporator 500 with the condensed water and used for humidification is increased, and then the quantity of the vapor in the condensed water taken away is large, the humidification effect is good, the problems of high humidity reduction speed and large humidity fluctuation in the refrigeration process are further avoided, the humidity fluctuation range in the whole wine storage cabinet in the refrigeration process is ensured to be small, and the original constant humidity can be basically maintained.

In this embodiment, when the evaporator 500 performs cooling, since the air flow passes through the first flow channel 330 and the second flow channel 340, condensed water is also generated on the air duct cover plate 200 and the inner container rear wall 111, and the air flow blown out from the air supply device 700 and blown to the evaporator 500 takes away a part of water vapor in the condensed water on the air duct cover plate 200 and the inner container rear wall 111 when passing through the first flow channel 330 and the second flow channel 340, so as to further increase the amount of the taken water vapor and enhance the humidification effect.

In the embodiment, the humidifying of the wine storage cavity 151 adopts the condensed water on the surface of the evaporator 500 and the condensed water collected by the water storage element 600, so that an external water box is not needed to be arranged separately during humidifying, and the occupation of the inner space of the wine storage cavity 151 is reduced. Meanwhile, in the humidification process, the air flow automatically flows through the surface of the evaporator 500 to take away the condensed water for automatic humidification, so that manual humidification water addition into the water storage element 600 is not needed, and the user experience is improved.

In order to realize constant control of the humidity and the temperature in the whole wine cabinet, a controller is further arranged in the embodiment and is connected and communicated with the air supply device 700; in order to detect the humidity and the temperature inside the wine cabinet, a temperature and humidity detecting element 800 is further provided in the embodiment, as shown in fig. 1. The temperature and humidity detecting element 800 comprises a temperature sensor 810 and a humidity sensor 820, which are respectively used for detecting the temperature and the humidity in the wine storage cavity 151, wherein the temperature sensor 810 and the humidity sensor 820 are connected with the controller, and the detected temperature value and the detected humidity value are sent to the controller. As a preferred embodiment, the humidity sensor 820 and the temperature sensor 810 in this embodiment are both disposed at a position close to the air inlet 310 or around the air inlet 310, the humidity and the temperature of the air collected from the air inlet 310 are the humidity and the temperature closest to the wine storage cabinet, and by detecting the humidity and the temperature at the position of the air inlet 310, a more accurate humidity value and temperature value in the wine storage cavity 151 can be obtained. When the controller detects that the temperature value in the wine storage cavity 151 is higher than the set temperature, the compressor is controlled to operate, and the evaporator 500 refrigerates to cool. If the humidity value is detected to be decreased, the controller may control the air blowing device 700 to operate to generate an air flow flowing to the evaporator 500 and the water storage element 600, so as to convert the condensed water formed on the surface of the evaporator 500 and the water stored in the water storage element 600 into steam, and the steam is blown into the wine storage cavity 151 along with the air flow, thereby implementing a humidifying function. Of course, the compressor and the blower 700 may be controlled to operate simultaneously, and humidification may be performed while cooling. The synchronous humidification in the refrigeration process compensates the humidity in the wine cabinet, and the problem that the fluctuation of the internal humidity is large due to the refrigeration of the wine cabinet can be effectively solved.

In order to ensure the uniformity of the temperature and humidity inside the wine storage cavity 151, in this embodiment, an air guiding channel 400 is further provided, as shown in fig. 13-17, which is formed in the air duct 300 and is used for guiding and blowing out the air flow at the bottom of the air duct 300 to the air outlet 321 at the top of the air duct cover plate 200, and through the air guiding channel 400, the air flow with cold energy at the bottom of the air duct 300 can be guided to the top air outlet 321 to be blown out to the top area of the wine storage cavity 151; because the air blowing device 700 in this embodiment is operated in a reverse air-suction mode, it sucks air from the top of the wine storage cavity 151 and blows the air flow to the evaporator 500, and then the air flow is discharged from the air outlets 321 at different height positions, because the air flow blown out from the air outlet 321 at the top position into the wine storage cavity 151 does not substantially pass through the evaporator 500, the temperature and humidity of the air flow blown out therefrom cannot meet the requirements, and the air flow blown out from the middle after partial flow passes through the evaporator 500 or the air flow blown out from the bottom after completely passing through the evaporator 500 is lower in temperature and higher in humidity, at this time, the temperature in the top area of the wine storage cavity 151 is high, the humidity is low, and the humidity in the bottom area of the wine storage cavity 151 is high and the temperature is low. In this embodiment, can be with the leading-in top of the wet cold air current of bottom through setting up an air guide channel 400, and blow to the top region of storing up wine chamber 151 from top air exit 321, and then reduced the temperature of storing up the regional department in wine chamber 151 top, the humidity that stores up wine chamber 151 top region has been increaseed, and simultaneously, because the wet cold air current of bottom is by the water conservancy diversion to the top, the humidity of storing up the regional department in wine chamber 151 bottom has also been reduced, make temperature and humidity in the wine chamber 151 of storing up more even, the constant temperature and humidity of gradevin have been guaranteed.
