If the direction of the air flow blown out by the second air supply device 600 is parallel, only a small amount of air flow passes through the bottom of the wine storage cavity 120, the refrigerating and humidifying effect at the bottom area of the wine storage cavity 120 is poor, so that the humidity and the temperature inside the whole compartment are uneven, in this embodiment, the second air supply device 600 blows out towards the bottom of the wine storage cavity 120 when the air flow is set, so that the humidified air flow is blown to the bottom of the wine storage cavity 120 first, then the air flow at the bottom position is sucked upwards through the suction effect of the first air supply device 400 at the top position, and further the air flow can flow in a uniform circulation way inside the whole wine storage cavity 120, so that the refrigerating and humidifying effect of the wine cabinet is better.
In order to ensure that the air flow blown out from the air outlet 210 can be blown into the water storage container 500, an air guiding member 920 for guiding the air from the air outlet 210 to the water storage container 500 is further provided at the bottom of the air duct 200 near the air outlet 210. The air guide 920 may be connected between the rear back plate of the liner 110 and the water storage container 500, or between the duct cover 130 and the water storage container 500, without being particularly limited thereto.
The invention also provides a temperature and humidity control method for the wine cabinet in the embodiment, which comprises the following steps: the start and stop of the compressor is controlled primarily by the temperature in the wine storage chamber 120.
The set temperature in the wine storage cavity 120 is pre-stored in the controller, and when the difference between the temperature in the wine storage cavity 120 and the set temperature is larger than a first threshold value, the temperature in the wine storage cavity 120 is higher, and the compressor needs to be started for refrigeration;
when the difference between the temperature in the wine storage cavity 120 and the set temperature is smaller than the first threshold value, the compressor is not required to be started for refrigeration;
when the difference between the temperature in the wine storage chamber 120 and the set temperature is smaller than the second threshold value, the temperature in the wine storage chamber 120 is lower, and at this time, the compressor needs to be controlled to stop refrigerating.
Meanwhile, a range of relatively constant humidity corresponding to the wine storage cavity 120 is prestored in the controller, namely, the humidity in the wine storage cavity 120 is defaulted to be constant humidity when the humidity is between a first preset humidity value and a second preset humidity value;
when the humidity in the wine storage chamber 120 is less than the second preset humidity, it indicates that the humidity in the wine storage chamber 120 is low,
when the humidity in the wine storage cavity 120 is greater than the second preset humidity and less than the first preset humidity, it indicates that the humidity in the wine storage cavity 120 is relatively constant;
when the humidity in the wine storage chamber 120 is greater than the first preset humidity, it represents that the humidity in the wine storage chamber 120 is higher.
When the temperature is set, the set temperature can be set in the controller to be TS, the temperature of the wine storage cavity is T1, the humidity in the wine storage cavity is d1, and the first threshold value is as follows: 0.5, the second threshold is-0.5, the first preset humidity value is 70%, and the second preset humidity value is 50%.
Specifically, when the wine cabinet is in operation, the temperature in the wine storage cavity 120 is detected firstly, when the difference between the temperature in the wine storage cavity 120 and the set temperature is detected to be greater than a first threshold value, the compressor is started to perform refrigeration, in order to ensure the humidity in the wine storage cavity 120, the humidity value in the wine storage cavity 120 is further detected at this time, if the humidity in the wine storage cavity 120 is detected to be less than a first preset humidity, the first refrigeration cycle loop is controlled to be conducted, the first air supply device 400 and the second air supply device 600 are controlled to work simultaneously, and specifically, in the embodiment, the humidity in the wine storage cavity 120 is less than the first preset humidity and is divided into two different conditions: the first case is: the humidity is smaller than the second preset humidity, when the humidity in the wine storage cavity 120 is smaller than the second preset humidity, the humidity value in the wine storage cavity 120 is lower, meanwhile, the temperature in the wine storage cavity 120 also reaches the starting temperature corresponding to the compressor, at the moment, the first refrigeration cycle loop is required to be controlled to be conducted, the compressor controls the evaporator 300 to cool the interior of the wine storage cavity 120, the pipeline corresponding to the first refrigeration cycle loop is the pipeline where the first capillary throttling piece 710 is located, the flow rate of the pipeline corresponding to the second capillary throttling piece 720 is large, and the refrigerating capacity is large, so that the first refrigeration cycle loop is controlled to be conducted in order to ensure that the temperature in the wine storage cavity 120 can reach the set temperature quickly;
meanwhile, the second air supply device 600 and the first air supply device 400 are controlled to work simultaneously, so that the humidifying airflow flows in the wine storage cavity 120 in a rapid circulating way to realize rapid humidification, so that the humidity in the wine storage cavity 120 can rapidly reach relatively constant humidity, and the first refrigeration circulation loop can be controlled to be disconnected when the difference between the temperature in the wine storage cavity 120 and the set temperature is smaller than a second threshold value, namely, the shutdown temperature of the compressor is reached;
the second case is: the humidity in the wine storage cavity 120 is between the second preset humidity and the first preset humidity, at this time, the humidity in the wine storage cavity 120 is relatively constant, but the temperature cannot meet the requirement, at this time, the first refrigeration cycle loop needs to be controlled to be conducted, the first air supply device 400 and the second air supply device 600 work, refrigeration is realized by conducting the first refrigeration cycle loop, and the first air supply device 400 and the second air supply device 600 are opened to keep the humidity in the wine storage cavity 120 constant.
In the setting, the rotation speeds of the first blower 400 and the second blower 600 may be reduced.
If the humidity in the wine storage cavity 120 is detected to be higher than the first preset humidity, the humidity in the wine storage cavity 120 is higher, but the temperature in the wine storage cavity 120 does not meet the requirement, at this time, only the first refrigeration cycle loop is controlled to be conducted, the first air supply device 400 is controlled to work, refrigeration is performed through the first refrigeration cycle loop, meanwhile, the first air supply device 400 drives the driving air flow to flow in the wine storage cavity 120 to realize humidification, the second air supply device 600 is stopped to work, and the first refrigeration cycle loop is controlled to be disconnected until the difference between the temperature in the wine storage cavity 120 and the set temperature is smaller than the second threshold value;
if the difference between the temperature in the wine storage cavity 120 and the set temperature is detected to be smaller than the first threshold value, the evaporator 300 is not required to be controlled to refrigerate by the compressor, at this time, the humidity in the wine storage cavity 120 is further detected, if the humidity in the wine storage cavity 120 is detected to be smaller than the second preset humidity, the first air supply device 400 and the second air supply device 600 are controlled to be started to operate, namely, the humidity value in the wine storage cavity 120 is lower at this time, and the temperature in the wine storage cavity 120 meets the temperature requirement, at this time, only the first air supply device 400 and the second air supply device 600 are controlled to be started, so that the air flow circularly flows in the wine storage cavity 120 to achieve the effect of rapid humidification.
If the humidity of the wine storage cavity 120 is detected to be greater than the second preset humidity and smaller than the first preset humidity, that is, the temperature and the humidity in the whole wine storage cavity 120 meet the requirements of the temperature and the humidity, at this time, the first air supply device 400 and the second air supply device 600 are controlled to stop working, and the first refrigeration cycle loop and the second refrigeration cycle loop are disconnected;
if the humidity of the wine storage chamber 120 is detected to be greater than the first preset humidity, the first air supply device 400 is controlled to be turned on, the second air supply device 600 is controlled to be turned off, and the second refrigeration cycle is conducted.
When the humidity in the wine storage cavity 120 is higher than the first preset humidity, which means that the humidity in the wine storage cavity 120 is higher, and meanwhile, the temperature in the wine storage cavity 120 meets the requirement, at this time, the second refrigeration cycle loop is controlled to be conducted, and because the second capillary throttling element 720 is arranged on the second refrigeration cycle loop, the length of the second capillary throttling element is longer, the refrigerant flow is throttled when passing through the second capillary throttling element 720, the pressure is fast reduced, the flow becomes low, meanwhile, the temperature on the evaporator 300 is rapidly reduced, the temperature becomes very low, so that a large amount of water vapor can be condensed on the surface of the evaporator, and rapid dehumidification is realized, and meanwhile, the first air supply device 400 can be started, so that the air flow can rapidly circulate in the wine storage cavity 120, thereby realizing rapid condensation of the water vapor and accelerating the dehumidification efficiency.
The above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be apparent to one skilled in the art that modifications may be made to the technical solutions described in the foregoing embodiments, or equivalents may be substituted for some of the technical features thereof; such modifications and substitutions do not depart from the spirit and scope of the corresponding technical solutions.
