[0033] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0034] Reference below Figure 1-Figure 3A storage device according to an embodiment of the present application is described.

[0035] The present application embodiment provides a storage device, such as Figure 1 and Figure 2 As shown, the storage device includes a box, a first evaporator 100 , a compressor assembly 200 , a condenser, a first branch 700 and a second branch 800 .

[0036] Among them, such as Figure 1 and Figure 2 As shown, the storage equipment in this embodiment can be understood as refrigeration storage equipment in a broad sense, including but not limited to refrigerators, freezers, display cabinets, beverage cabinets, wine cabinets, cold storage cabinets and refrigerated vending machines and other refrigeration storage equipment. The storage equipment has diverse structural forms and a wide range of applications.

[0037] The box body of the storage device defines a compartment and an air duct. The compartment is used to place items. The compartment can be one or more. For example, when the storage device is a refrigerator, the compartment can be multiple, and the compartment includes a refrigeration compartment and a freezer compartment; when the storage device is a small freezer, the compartment can be one.

[0038] like Figure 1 and Figure 2 As shown, the storage device also includes a fan 900, and an air outlet and a return air outlet are provided in the compartment. The air outlet and the return air outlet are both connected to the air duct. The fan 900 can be provided in the air duct or at the air outlet of the compartment. The air in the air duct and the compartment is circulated through the fan 900.

[0039] like Figure 1 and Figure 2 As shown, the first evaporator 100, the compressor assembly 200, the condenser, the first branch 700 and the second branch 800 are connected to form a refrigeration circuit of the storage device, and the refrigeration circuit is used for the flow of refrigerant.

[0040] like Figure 1 and Figure 2 As shown, the first evaporator 100 is installed in the air duct for cooling the air in the air duct. When the refrigerant flows through the first evaporator 100, it evaporates in the first evaporator 100 and absorbs heat from the air in the air duct, thereby reducing the temperature of the air in the air duct.

[0041] like Figure 1 and Figure 2 As shown, the compressor assembly 200 is installed in the box, and the outlet of the first evaporator 100 is connected to the inlet of the compressor assembly 200. The compressor is used to compress the refrigerant after absorbing heat to increase the temperature.

[0042] like Figure 1 and Figure 2As shown, the condenser is installed in the box, the outlet of the compressor assembly 200 is connected to the inlet of the condenser, and the condenser may include a back condenser 300 and a side plate condenser 400. The back condenser 300 is arranged on the back of the box, and the side plate condenser 400 is arranged on the side of the box. The outlet of the compressor assembly 200 is connected to the inlet of the back condenser 300, and the outlet of the back condenser 300 is connected to the inlet of the side plate condenser 400.

[0043] like Figure 1 and Figure 2 As shown, the storage device may further include a drying filter 500, and the outlet of the side plate condenser 400 is connected to the inlet of the drying filter 500, that is, the first evaporator 100, the compressor assembly 200, the back condenser 300, the side plate condenser 400 and the drying filter 500 are connected in sequence to form part of a refrigeration circuit.

[0044] like Figure 1 As shown, the first branch 700 and the second branch 800 are connected in parallel between the inlet of the first evaporator 100 and the outlet of the condenser. When the storage device includes a drying filter 500, the first branch 700 and the second branch 800 are connected in parallel between the inlet of the first evaporator 100 and the outlet of the drying filter 500, thereby forming a closed refrigeration circuit with the first evaporator 100, the compressor assembly 200, the back condenser 300, the side plate condenser 400 and the drying filter 500.

[0045] like Figure 1 As shown, a first throttling device 710 is provided on the first branch 700. The first throttling device 710 is provided between the first evaporator 100 and the drying filter 500. The first throttling device 710 can be a capillary tube, a float valve, an expansion valve or other devices capable of throttling.

[0046] like Figure 1 As shown, the second branch 800 is provided with a second throttling device 820 and a second evaporator 810 connected in series. The second throttling device 820 can also be a capillary tube, a float valve, an expansion valve or other devices capable of throttling.

[0047] like Figure 1 and Figure 2 As shown, the second evaporator 810 is installed in the air duct and is used to dehumidify the air in the air duct. When the refrigerant flows through the second evaporator 810, it evaporates in the second evaporator 810 and absorbs heat from the air in the air in the air duct, and reduces the temperature of the water vapor in the air to a level where it can condense into frost and remain in the second evaporator 810.

[0048] It should be noted that if Figure 2As shown, when the air circulates in the storage device, the air first passes through the second evaporator 810 in the air duct and then passes through the first evaporator 100.

[0049] One of the first branch 700 and the second branch 800 is connected. When the first branch 700 is connected, the refrigerant flows through the drying filter 500 and then passes through the first throttling device 710 and directly flows into the first evaporator 100; when the second branch 800 is connected, the refrigerant flows through the drying filter 500 and then passes through the second throttling device 820 and the second evaporator 810 in sequence and then flows into the first evaporator 100.

[0050] In the actual implementation process, Figure 1 and Figure 2 As shown, when dehumidification is not required inside the storage device, the first branch 700 is connected, and the refrigerant is compressed by the compressor and flows through the back condenser 300 and the side plate condenser 400 in sequence, and is dried and filtered in the drying filter 500. After passing through the first throttling device 710 in the first branch 700, it flows into the first evaporator 100. At the same time, the fan 900 is turned on, and the fan 900 circulates the air in the compartment and the air duct. The air passes through the second evaporator 810 and the first evaporator 100 in the air duct. When the air flows through the first evaporator 100, the refrigerant absorbs the heat of the air in the first evaporator 100 to reduce the temperature of the air. The cooled air is blown into the compartment by the fan 900, thereby reducing the temperature of the compartment.

[0051] like Figure 1 and Figure 2 As shown, when the storage device needs to be dehumidified, the second branch 800 is connected, and the refrigerant is compressed by the compressor and flows through the back condenser 300 and the side plate condenser 400 in sequence, and is dried and filtered in the drying filter 500. In the second branch 800, it passes through the second throttling device 820 and the second evaporator 810 in sequence. At the same time, the fan 900 is turned on, and the fan 900 circulates the air in the compartment and the air duct. The air passes through the second evaporator 810 and the first evaporator 100 in the air duct. When the air When the air flows through the second evaporator 810, the refrigerant absorbs the heat of the air in the second evaporator 810, so that part of the water vapor in the air condenses on the second evaporator 810, and at the same time cools the uncondensed air. The refrigerant continues to flow into the first evaporator 100, and the uncondensed air also continues to flow in the air duct to the first evaporator 100, and exchanges heat with the refrigerant in the first evaporator 100 to further cool it down. The cooled air is blown into the compartment by the fan 900, thereby lowering the temperature of the compartment.

[0052] like Figure 1 and Figure 2As shown, when the interior of the storage device needs to be humidified, the first branch 700 is connected, and the refrigerant is compressed by the compressor and flows through the back condenser 300 and the side plate condenser 400 in sequence, and is dried and filtered in the drying filter 500. After passing through the first throttling device 710 in the first branch 700, it flows into the first evaporator 100. At the same time, the fan 900 is turned on, and the fan 900 circulates the air in the compartment and the air duct. The air passes through the second evaporator 810 and the first evaporator 100 in the air duct. Since the second evaporator 810 does not work during humidification, its own temperature gradually increases. Therefore, part of the water vapor condensed on the second evaporator 810 can melt and be carried away to the compartment by the air flowing through the second evaporator 810, thereby achieving humidification of the storage device.

[0053] According to the storage device provided in the embodiment of the present application, through the arrangement of the above-mentioned first branch 700, the second branch 800 and the second evaporator 810, the air can only be cooled when the storage device does not need dehumidification, thereby reducing energy consumption. When the storage device needs dehumidification, the second evaporator 810 is used to condense water vapor and directly perform low-temperature dehumidification on the air, thereby improving the accuracy of humidity control of the storage device. At the same time, the second evaporator 810 can pre-cool the air so that the air can be cooled to a lower temperature in the first evaporator 100, thereby reducing the impact of humidity on the internal temperature of the storage device during dehumidification.

[0054] In some embodiments, as Figure 1 and Figure 2 As shown, the first evaporator 100 is an inflation evaporator; and / or, the second evaporator 810 is a fin evaporator.

[0055] Among them, such as Figure 1 and Figure 2 As shown, the first evaporator 100 is an inflation evaporator, and the second evaporator 810 is a fin evaporator.

[0056] It can be understood that the heat transfer area of ​​the fin evaporator is larger than that of the blown evaporator. At the same time, the performance of the fin evaporator itself can cool the air to a lower temperature. Therefore, setting the second evaporator 810 as a fin evaporator can improve the efficiency of water vapor condensation in the second evaporator 810 and improve the dehumidification effect of the storage equipment. At the same time, since the first evaporator 100 is used to cool the air in the air duct and the temperature of the blown evaporator is relatively high, it is difficult for water vapor to condense in the blown evaporator after passing through the blown evaporator. Therefore, setting the first evaporator 100 as a blown evaporator can reduce the amount of water vapor condensed in the first evaporator 100. Even if a small amount of water vapor condenses in the first evaporator 100, the blown evaporator can automatically melt the condensed water vapor after shutdown, without the need for a separate defrosting operation, thereby reducing costs to a certain extent.

[0057] In some embodiments, as Figure 1 As shown, the storage device further includes a three-way valve 600, a humidity sensor and a controller.

[0058] Among them, such as Figure 1 As shown, the three-way valve 600 may be a solenoid valve, an electric valve or other types of three-way valves 600 . For example, the three-way valve 600 is a solenoid valve.

[0059] like Figure 1 As shown, the three-way valve 600 has a first port, a second port and a third port. The first port of the three-way valve 600 is connected to the outlet of the condenser, the second port of the three-way valve 600 is connected to the first branch 700, and the third port of the three-way valve 600 is connected to the second branch 800. One of the second port and the third port is connected to the first port, and the connection of the first branch 700 or the second branch 800 is achieved through one of the second port and the third port in the three-way valve 600 being connected to the first port.

[0060] The humidity sensor is installed in the compartment to collect humidity information in the compartment. The controller is electrically connected to the three-way valve 600 to control the connection state of the three-way valve 600 based on the humidity information collected by the humidity sensor.

[0061] During actual implementation, the humidity sensor collects humidity information in the compartment in real time. When the humidity sensor detects that the humidity in the compartment is greater than a preset range, it sends a signal to the controller. The controller controls the first port and the third port of the three-way valve 600 to be connected, that is, the second branch 800 is connected, and the second evaporator 810 is used to dehumidify the air in the air duct, thereby reducing the humidity of the air flowing into the compartment.

[0062] When the humidity sensor detects that the humidity in the compartment is within or below a preset range, a signal is sent to the controller, which controls the first port of the three-way valve 600 to connect with the second port, that is, the first branch 700 is connected. At this time, only the first evaporator 100 is used to cool the air in the air duct, thereby maintaining the temperature in the storage device. At the same time, some condensed water vapor on the second evaporator 810 melts, which can increase the humidity of the air flowing into the compartment to a certain extent.

[0063] Through the setting of the above-mentioned three-way valve 600, humidity sensor and controller, the humidity information collected by the humidity sensor can be used to accurately control the on and off of the first branch 700 and the second branch 800, thereby further improving the accuracy of the storage device in controlling the humidity. At the same time, the setting of the three-way valve 600 can facilitate the switching of the first branch 700 and the second branch 800.

[0064] In some embodiments, the storage device further includes a heater, which is installed on the second evaporator 810 . The controller is electrically connected to the heater and is configured to control the operating state of the heater based on humidity information collected by the humidity sensor.

[0065] The heater may be a resistance wire heater, a ceramic heater, a quartz tube heater or other types of heaters.

[0066] During the actual implementation process, when the humidity sensor detects that the humidity in the compartment is less than a preset range, a signal is sent to the controller. The controller controls the first port of the three-way valve 600 to be connected to the second port, and controls the heater to start. Under the heating action of the heater, the water vapor condensed on the second evaporator 810 melts and drips into the water receiving tray in the air duct. Since the air in the compartment needs to pass through the air duct when circulating, the air takes away part of the water vapor and flows back into the compartment when flowing through the water receiving tray in the air duct, thereby increasing the humidity of the air in the compartment. When the air with increased humidity passes through the first evaporator 100, it is difficult for water vapor to condense in the first evaporator 100. Therefore, the first evaporator 100 can be used to cool the air before entering the compartment, thereby increasing the humidity while lowering the temperature.

[0067] By setting the above-mentioned heater, the melting speed of the condensed water vapor on the second evaporator 810 can be increased, thereby improving the defrosting effect of the second evaporator 810 and improving the humidification efficiency and humidification effect of the storage device.

[0068] In some embodiments, as Figure 3 As shown, the storage device has a first working mode. When the storage device is in the first working mode, the first port of the three-way valve 600 is connected to the second port of the three-way valve 600, and the heater is in working state.

[0069] Among them, such as Figure 3 As shown, when the storage device is in the first working mode, the storage device is in a humidifying state.

[0070] In the actual implementation process, Figure 1 and Figure 3 As shown, when the humidity sensor detects that the humidity in the compartment is less than a preset range, a signal is sent to the controller, and the controller controls the first port of the three-way valve 600 to be connected to the second port, that is, the first branch 700 is connected, and controls the heater to start. Under the heating action of the heater, the water vapor condensed on the second evaporator 810 melts and drips into the water receiving tray in the air duct. Since the air in the compartment needs to pass through the air duct when circulating, the air takes away part of the water vapor when flowing through the water receiving tray in the air duct and flows back into the compartment, thereby increasing the humidity of the air in the compartment. When the air with increased humidity passes through the first evaporator 100, it is difficult for the water vapor to condense in the first evaporator 100. Therefore, the first evaporator 100 can be used to cool the air before entering the compartment, thereby increasing the humidity while lowering the temperature.

[0071] By setting the first working mode, the humidity of the storage device can be increased when the humidity inside the storage device is insufficient, so that the items stored in the compartment can be preserved in a suitable environment, thereby extending the use or edible period of the items.

[0072] In some embodiments, as Figure 1 and Figure 3 As shown, the storage device has a second working mode. When the storage device is in the second working mode, the heater is in operation, and the first evaporator 100, the compressor assembly 200, the condenser and the second evaporator 810 are all in shutdown.

[0073] Among them, such as Figure 1 and Figure 3 As shown, when the storage device is in the second working mode, the storage device is in a defrosting state.

[0074] In the actual implementation process, Figure 1 and Figure 3 As shown, when too much water vapor condenses on the second evaporator 810, or before starting the storage device, the storage device can be placed in the second working mode. At this time, except for the heater in the refrigeration circuit, all other components are in the shutdown state. The heater heats the second evaporator 810 to melt the water vapor condensed on the second evaporator 810, and the melted water vapor drips into the water receiving tray in the air duct.

[0075] By setting the above-mentioned second working mode, the heater can be used to melt the water vapor on the second evaporator 810 before the storage device is started, or when too much water vapor condenses on the second evaporator 810, thereby reducing the probability of excessive condensation of water vapor affecting the operation of the second evaporator 810. At the same time, the remaining equipment in the refrigeration circuit is in a shutdown state, which can reduce the impact of the lower temperature air circulating in the compartment and the air duct on the melting efficiency of water vapor.

[0076] In some embodiments, the height of the first evaporator 100 is greater than the height of the second evaporator 810 .

[0077] The first evaporator 100 and the second evaporator 810 are both arranged in an air duct. The air duct can be arranged in a vertical direction, or can be arranged at an angle relative to the vertical direction, or can be arranged in other ways.

[0078] The height of the first evaporator 100 is greater than that of the second evaporator 810 , and the height of the fan 900 is greater than that of the first evaporator 100 . Air enters the air duct and passes through the second evaporator 810 , the first evaporator 100 and the fan 900 in sequence.

[0079] During actual implementation, when the storage device is in the first operating mode or the second operating mode, the heater is in working state, the water vapor condensed on the second evaporator 810 melts and drips downward under the action of gravity. Since the first evaporator 100 and the fan 900 are both located above the second evaporator 810, the dripping water vapor can fall directly into the water receiving tray.

[0080] By setting the height of the first evaporator 100 to be greater than the height of the second evaporator 810 , the probability of water vapor dripping from the second evaporator 810 during defrosting and affecting the first evaporator 100 can be reduced, thereby extending the service life of the first evaporator 100 .

[0081] In some embodiments, the second evaporator 810 is disposed at the bottom of the air duct.

[0082] The second evaporator 810 can be arranged at the bottom of the air duct, the first evaporator 100 can be arranged at the top of the air duct, and the water receiving tray can be arranged at the bottom of the air duct, and the air enters from the bottom of the air duct and flows out from the top of the air duct.

[0083] During actual implementation, when the storage device is in the first working mode or the second working mode, the heater is in working state, the water vapor condensed on the second evaporator 810 melts and drips downward under the action of gravity. Since the second evaporator 810 and the water receiving tray are both located at the bottom of the air duct, when the water receiving tray needs to be cleaned, the water receiving tray can be easily taken out from the bottom of the air duct.

[0084] By arranging the second evaporator 810 at the bottom of the air duct, it is convenient to take out the water collecting tray from the bottom of the air duct for cleaning, and it is convenient to repair and replace the second evaporator 810. At the same time, the first evaporator 100 is arranged at the top of the air duct, which is convenient to repair and replace the first evaporator 100.

[0085] In some embodiments, as Figure 1 and Figure 3 As shown, the storage device has a third working mode. When the storage device is in the third working mode, the first branch 700 is connected and the second branch 800 is not connected.

[0086] Among them, such as Figure 1 and Figure 3 As shown, when the storage device is in the third working mode, neither humidification nor dehumidification is required inside the storage device. At this time, the first branch 700 is connected and the second branch 800 is not connected, that is, the second evaporator 810 is in a shutdown state.

[0087] During actual implementation, when the storage device is in the third working mode, the inlet of the first evaporator 100 is connected to the outlet of the drying filter 500 through the first branch 700. At this time, the refrigerant circulates in the refrigeration circuit, and the air in the air duct passes through the second evaporator 810 and the first evaporator 100 in turn and flows into the compartment. Since the second evaporator 810 is in a shutdown state, it is difficult for the air to condense on the second evaporator 810 when passing through the second evaporator 810. Therefore, the air in the air duct is blown into the compartment by the fan 900 only after being cooled in the first evaporator 100.

[0088] By setting the third working mode, the energy consumption of the second evaporator 810 can be reduced when the storage device does not need humidification and dehumidification, thereby reducing costs to a certain extent.

[0089] In some embodiments, as Figure 1 and Figure 3 As shown, the storage device has a fourth working mode. When the storage device is in the fourth working mode, the second branch 800 is connected and the first branch 700 is not connected.

[0090] Among them, such as Figure 1 and Figure 3 As shown, when the storage device is in the fourth working mode, the interior of the storage device needs to be dehumidified.

[0091] During the actual implementation process, when the storage device is in the fourth working mode, when the air in the air duct passes through the second evaporator 810, most of the water vapor in the air condenses on the second evaporator 810 to achieve dehumidification of the air in the air duct. The remaining air is cooled down under the action of the second evaporator 810, and continues to flow through the first evaporator 100, further cooled down in the first evaporator 100, and finally blown into the room by the fan 900.

[0092] By setting the fourth working mode, the second evaporator 810 can be used to dehumidify the air in the air duct when the storage device needs to be dehumidified, and the switching method is simple.
