Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration, and particularly to refrigeration equipment. Background Art

[0002] With the improvement of people's living standards, the demand for red wine and cigars has increased. Red wine and cigars have strict requirements for storage temperature and humidity. Temperatures and humidity outside the standard range will directly affect their taste and texture. Currently, the wine cabinets or cigar cabinets on the market adopt direct refrigeration methods and cannot accurately control the evaporation temperature. Due to the start and stop of the compressor, the temperature fluctuates greatly, which in turn leads to large fluctuations in the humidity inside the cabinet. When the humidity is too low, the cork of the red wine is prone to cracking, and air enters the wine bottle, resulting in the oxidation and deterioration of the stored wine. When the humidity is too high, the cork is prone to mildew, causing damage to the wine. For cigars, low humidity will cause the cigar wrapper to crack, and high humidity will cause the cigars to mildew. Therefore, it is necessary to study a refrigeration device to solve the above problems. Summary of the Invention

[0008] As a further improvement of an embodiment of the present invention, the refrigeration device further includes an air duct plate cooperatively arranged with the evaporation plate. The air duct plate extends downward from a position near the lower end of the evaporation plate and, together with the evaporation plate, separates the cooling chamber and the cold air circulation chamber. The air inlet is formed on the air duct plate.

[0009] As a further improvement of an embodiment of the present invention, the blower is fixedly mounted on the heat-conducting partition board forwardly, and has a suction port opposite to the air inlet and an air outlet opening towards the cold air circulation chamber.

The blower is fixed to the rear wall of the partition board body and disposed at the bottom of the flow-dividing guide plates;

A fan is provided in the cooling chamber or the cold air circulation chamber. The cold energy generated by the plate evaporator enters the cold air circulation chamber in the form of cold air under the promotion of the fan and conducts the cold energy to the heat conduction partition. The heat conduction partition radiates and transfers the cold energy to the air in the storage room to complete the refrigeration of the storage room. After the cold air exchanges heat with the heat conduction partition, it becomes hot air and then enters the cooling chamber to exchange heat with the plate evaporator to become cold air, thus completing the refrigeration cycle. Since the dry cold air in the cooling chamber does not enter the storage room and the storage room is no longer refrigerated by the forced circulation of low-temperature cold air, the moisture in the storage room will not be taken away, which is beneficial to controlling the humidity in the storage room. It has the advantages of high refrigeration efficiency, controllable humidity, high space utilization rate, and compact structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following elaborates on the preferred embodiments of the present invention in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making the protection scope of the present invention more clearly defined.

[0032] The terms "comprising" and "having" and any variations thereof in the present invention are intended to cover non-exclusive inclusion. Mentioning "embodiment" in this article means that the specific features, structures or characteristics described in connection with the embodiment can be included in at least one embodiment of the present application. The phrase appears at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0033] Combined with Figure 1 As shown, the present invention mainly relates to: a refrigeration device, which includes a cabinet 1. The cabinet 1 includes an inner liner 11, and the inner liner 11 defines a storage compartment 12. The inner liner 11 includes a rear wall 13 of the inner liner. The refrigeration device in this embodiment is explained by taking a refrigerator as an example. The inner liner 11 further includes an opening of the inner liner, and the opening of the inner liner is disposed opposite to the rear wall 13 of the inner liner.

[0034] Preferably, the refrigeration device is configured as a refrigerator for storing red wine and / or cigars.

[0035] Combined with Figure 2 And Figure 3 As shown, in this embodiment, the refrigeration device further includes a heat conduction partition 2 disposed in the inner liner 11. One side of the heat conduction partition 2 forms a storage compartment 12. The other side of the heat conduction partition 2 includes a cooling chamber 35.

[0036] Furthermore, the refrigeration device further includes a plate evaporator 3 disposed between the heat conduction partition 2 and the rear wall 13 of the inner container. The plate evaporator 3 and the heat conduction partition 2 are sequentially arranged at intervals in the direction from the rear to the front.

[0037] A cooling chamber 35 is defined between the plate evaporator 3 and the rear wall 13 of the inner container, and a cold air circulation chamber 25 communicating with the cooling chamber 35 is defined between the plate evaporator 3 and the heat conduction partition 2. A blower 4 is disposed in the cooling chamber 35 or the cold air circulation chamber 25. The other side of the heat conduction partition 2 includes the cooling chamber 35 and the cold air circulation chamber 25. The cold generated by the plate evaporator 3 enters the cold air circulation chamber 25 in the form of cold air under the promotion of the blower 4 and conducts the cold to the heat conduction partition 2. After the cold air exchanges heat with the heat conduction partition 2, it becomes hot air and then enters the cooling chamber 35 to exchange heat with the plate evaporator 3 to become cold air, thus completing the refrigeration cycle.

[0038] Wherein, at least a part of the heat conduction partition 2 is exposed in the storage compartment 12 so that the cold of the plate evaporator 3 is radiated into the storage compartment 12 through the heat conduction partition 2. The cold on the heat conduction partition 2 exchanges heat with the heat load in the storage compartment 12, so as to achieve the purpose of cooling the storage compartment 12.

[0039] In the refrigeration device provided in this embodiment, the space between the heat conduction partition 2 and the inner container 11 is divided into a cooling chamber 35 and a cold air circulation chamber 25 by the plate evaporator 3. The plate evaporator 3 serves as a heat exchange component to provide cold for the storage compartment 12, and at the same time serves as a partition wall between the cooling chamber 35 and the cold air circulation chamber 25, enhancing the heat exchange efficiency, improving the space utilization rate, and reducing the cost. A blower 4 is disposed in the cooling chamber 35 or the cold air circulation chamber 25. The cold generated by the plate evaporator 3 enters the cold air circulation chamber 25 in the form of cold air under the promotion of the blower 4 and conducts the cold to the heat conduction partition 2. The heat conduction partition 2 radiates and transfers the cold to the air in the storage compartment 12 to complete the refrigeration of the storage compartment 12. After the cold air exchanges heat with the heat conduction partition 2, it becomes hot air and then enters the cooling chamber 35 to exchange heat with the plate evaporator 3 to become cold air, thus completing the refrigeration cycle. Since the dry cold air in the cooling chamber 35 does not enter the storage compartment 12 and the storage compartment 12 is no longer refrigerated by the forced circulation of low-temperature cold air, the moisture in the storage compartment 12 will not be taken away, which is beneficial to controlling the humidity in the storage compartment 12, and has the advantages of high refrigeration efficiency, controllable humidity, high space utilization rate, and compact structure.

[0040] Combined with Figure 4As shown, in this embodiment, the plate evaporator 3 includes an evaporation plate 31 arranged in parallel with the rear wall 13 of the inner container, and a refrigeration pipeline 32 arranged on the evaporation plate 31. The cooling chamber 35 and the cold air circulation chamber 25 are respectively communicated at the upper and lower ends of the evaporation plate 31. Specifically, there are intervals between the upper and lower ends of the evaporation plate 31 and the inner wall of the inner container 11 respectively, so that there are preset distances between the upper and lower ends of the evaporation plate 31 and the inner wall of the inner container 11 respectively. Or, through holes communicating the cooling chamber 35 and the cold air circulation chamber 25 are respectively arranged at the upper and lower ends of the evaporation plate 31.

[0041] Preferably, the plate evaporator 3 is set as a blown evaporator.

[0042] Further, an air return port 33 flowing from the cold air circulation chamber 25 to the cooling chamber 35 is formed above the evaporation plate 31, and an air inlet 34 flowing from the cooling chamber 35 to the cold air circulation chamber 25 is formed below the evaporation plate 31. Among them, the cold air in the cooling chamber 35 enters the cold air circulation chamber 25 from the air inlet 34 and flows upward, and then enters the cooling chamber 35 through the air return port 33 and flows downward to the air inlet 34. Thus, the cold air circulation between the cold air circulation chamber 25 and the cooling chamber 35 is completed.

[0043] The fan 4 is arranged at the position of the air inlet 34. The fan 4 sucks the cold air in the cooling chamber 35 through the air inlet 34 and discharges it upward.

[0044] Combined Figure 3 、 Figure 4 As shown, further, the refrigeration equipment further includes an air duct plate 36 arranged in cooperation with the evaporation plate 31. The air duct plate 36 extends downward from a position near the lower end of the evaporation plate 31, and together with the evaporation plate 31, separates the cooling chamber 35 and the cold air circulation chamber 25. The air inlet 34 is formed on the air duct plate 36. The air duct plate 36 includes a vertical portion extending upward to a position near the lower end of the evaporation plate 31 and a horizontal portion formed by bending the vertical plate backward.

[0045] The shape of the air inlet 34 is adapted to the shape of the fan 4 and is set as a circle.

[0046] Further, the fan 4 is fixedly mounted forward on the heat conduction partition plate 2. The fan 4 includes a fan and a fan housing for mounting the fan. The fan housing is fixed to the heat conduction partition plate 2 through fasteners.

[0047] The fan 4 has an air suction port 41 opposite to the air inlet 34 and an air discharge port 42 opening toward the cold air circulation chamber 25. The air suction port 41 of the fan 4 sucks the cold air in the cooling chamber 35 through the air inlet 34 and discharges it upward through the air discharge port 42.

[0048] Further, the heat-conducting partition 2 includes a partition body 21 and a plurality of diversion guide plates 22 formed by the partition body 21 extending backward. The fan 4 is fixed to the rear wall of the partition body 21 and is disposed at the bottom of the diversion guide plates 22.

[0049] Combined Figure 5 As shown, in this embodiment, further, the heat-conducting partition 2 further includes an arc-shaped air guide plate 24 formed by the partition body 21 extending backward for installing the fan 4. The arc-shaped air guide plate 24 defines an arc space for installing the fan 4. Preferably, the air outlet 42 faces upward.

[0050] Wherein, the lower end surfaces of the plurality of diversion guide plates 22 are disposed at the upper end opening of the arc space.

[0051] A diversion air duct 23 extending upward from the air outlet 42 of the fan 4 is defined between two adjacent diversion guide plates 22. The fan 4 sucks the cold air in the cooling chamber 35 through the air inlet 34 and discharges it upward through the plurality of diversion air ducts 23, so as to ensure that the cold quantity distribution of the heat-conducting partition 2 is relatively uniform, and improve the contact area between the cold air and the heat-conducting partition 2, enhance the radiation quantity and radiation efficiency of the cold quantity of the heat-conducting partition 2, and avoid waste of cold air. It has the advantages of energy saving, high efficiency and high refrigeration efficiency.

[0052] Further, a gap is preset between the evaporation plate 31 and the diversion guide plates 22 and the air duct plate 36 respectively, so that the defrosting water generated when the plate evaporator 3 defrosts flows downward along the evaporation plate 31 and is discharged.

[0053] Preferably, the size range of the gap is below 5 mm, and the occupied space is reduced as much as possible to improve the space utilization rate.

[0054] Further, the evaporation plate 31 is fixed to the inner container 11 through fasteners.

[0055] Further, the refrigeration device further includes a turbulent flow air duct 51 at least partially adjacent to the heat-conducting partition 2, a turbulent flow fan 4 disposed in the turbulent flow air duct 51, a turbulent flow air outlet 52, and a turbulent flow air return port 53.

[0056] Wherein, the turbulent flow air outlet 52 and the turbulent flow air return port 53 are respectively communicated with the turbulent flow air duct 51 and the storage compartment 12. The turbulent flow air duct 51 circulates the cold air in the storage compartment 12, which is beneficial to ensuring the temperature uniformity in the storage compartment 12.

[0057] Further, the heat-conducting partition 2 includes a heat-conducting partition body 21 and a fixing portion formed by the heat-conducting partition body 21 extending backward and being in limit snap connection with the rear wall;

[0058] The fixing portion includes a limit abutting plate and a hook disposed at the rear side of the limit abutting plate.

[0059] The rear wall includes a contact and cooperation part that cooperates with the limit contact plate and a card slot that cooperates with the hook.

[0060] Further, the turbulent flow air duct 51 includes a first air duct 511 disposed at the bottom of the inner container 11 and used to accommodate the turbulent flow fan 4, and a second air duct 512 extending upward from the first air duct 511 and disposed adjacent to the heat conduction partition plate 2. The first air duct 511 and the second air duct 512 are in communication with each other.

[0061] Wherein, the turbulent flow air outlet 52 is in communication with the second air duct 512, and the turbulent flow air return port 53 is in communication with the first air duct 511. The turbulent flow air return port 53 is disposed at the bottom of the storage compartment 12, and air returns through the turbulent flow air return port 53 at the bottom of the storage compartment 12. A turbulent flow air path with upper air outlet and bottom air return is formed. The hot air entering the turbulent flow air duct 51 from the turbulent flow air return port 53 at the bottom of the storage compartment 12 contacts and exchanges heat with the heat conduction partition plate 2 from bottom to top, becomes cold air and then enters the storage compartment 12 through the turbulent flow air outlet 52. The cold air naturally sinks and then passes through the turbulent flow air return port 53, having the advantages of reasonable turbulent flow path setting and high refrigeration efficiency.

[0062] Further, the refrigeration device further includes a turbulent flow guide plate 55 disposed on the side of the heat conduction partition plate 2 close to the storage compartment 12.

[0063] The turbulent flow guide plate 55 and the heat conduction partition plate 2 define the second air duct 512 therebetween, and the turbulent flow air outlet 52 is disposed at the upper part of the second air duct 512. Thus, the turbulent flow air duct 51 with bottom air return and upper air outlet is formed. The cold quantity received by the heat conduction partition plate 2 is guided to the storage compartment 12 through the turbulent flow air duct 51, thereby improving the refrigeration efficiency of the storage compartment 12.

[0064] Wherein, the turbulent flow plate is fixed relative to the heat conduction partition plate 2.

[0065] Further, the heat conduction partition plate 2 is provided with a dehumidification port 26 that communicates the cooling chamber 35 and the storage compartment 12. A dehumidification air door 27 for opening or closing the dehumidification port 26 is disposed at the dehumidification port 26.

[0066] Combined Figure 5 、 Figure 6 As shown, further, the humidity control system of the present invention includes a humidifying component and a dehumidifying component.

[0067] The inner container 11 defines a storage compartment 12 and a cooling chamber 35, and a partition wall is disposed in the inner container 11 between the storage compartment 12 and the cooling chamber 35.

[0068] The partition wall is provided with a dehumidification opening 26 that communicates with the storage room 12 and the cooling room 35. A dehumidification air damper 27 for opening or closing the dehumidification opening 26 is provided at the dehumidification opening 26. The dehumidification component includes the dehumidification opening 26 and the dehumidification air damper 27. When dehumidification is not required, there is no air flow exchange between the storage room 12 and the cooling room 35, so as to reduce the temperature and humidity fluctuations in the storage room 12. Fixed-point humidity control can be achieved to ensure that the humidity fluctuation in the storage room 12 is ±2%.

[0069] Specifically, after the dehumidification air damper 27 is opened, the storage room 12 and the cooling room 35 are communicated. Due to the large temperature difference between the cooling room 35 and the storage room 12, there is a pressure difference. When the dehumidification air damper 27 is opened, under the action of the pressure difference, the air in the storage room 12 and the refrigeration cavity forms natural convection, and the cold air in the cooling room 35 is used to dehumidify the storage room 12. Compared with multiple air dampers and air inlets, a single air inlet can better control the air exchange rate and frequency between the two rooms, further reducing the temperature and humidity fluctuations while ensuring the reliability of the dehumidification air damper 27.

[0070] The refrigeration device further includes a humidification component 6 that is respectively arranged in the inner container 11 and is adjacent to the storage room 12.

[0071] The humidification component 6 includes a water storage box 61 having a water storage cavity 611, a humidification air duct 62 that communicates the water storage cavity 611 with the storage room 12, and a humidification fan 63 located in the humidification air duct 62. The humidification fan 63 is configured to blow the humidified air in the water storage cavity 611 into the storage room 12. The humidification fan 63 is arranged in the humidification air duct 62 so that air circulates between the water storage cavity 611 and the storage room 12, thereby humidifying the storage room 12 with the humidified air.

[0072] Furthermore, the humidification component 6 is arranged at the bottom of the inner container 11. The humidification component 6 further includes a housing 64 provided on the top of the water storage box 61, a humidification air inlet 65 and a humidification air outlet 66 respectively formed on the housing 64. Among them, the upper side of the housing 64 forms the storage room 12. The housing 64 is arranged between the water storage box 61 and the storage room 12.

[0073] The humidification air inlet 65 and the humidification air outlet 66 are arranged at both ends of the humidification air duct 62 and respectively communicate the water storage cavity 611 with the storage room 12. The humidification air inlet 65 communicates the water storage cavity 611 with the storage room 12, and the humidification air outlet 66 communicates the water storage cavity 611 with the storage room 12.

[0074] Furthermore, the housing 64 includes a housing body 641 and a cover body 642 covering the top of the housing body 641, and the upper side of the cover body 642 forms the storage room 12.

[0075] The humidifying air inlet 65 includes a through air inlet hole 651 formed by the housing body 641, an air inlet channel 652 formed by the housing body 641 and communicating with the through air inlet hole 651, and an air inlet opening 653 formed by the cover body 642 and communicating the storage compartment 12 with the air inlet channel 652. The air inlet opening 653 is arranged facing the storage compartment 12. The through air inlet hole 651 penetrates the housing body 641 in the up and down direction to communicate the water storage cavity 611 with the air inlet channel 652. The air inlet channel 652 communicates the through air inlet hole 651 with the air inlet opening 653. The air in the storage compartment 12, under the promotion of the humidifying fan 63, sequentially passes through the air inlet opening 653, the air inlet channel 652, the humidifying fan 63, the through air inlet hole 651, and the water storage cavity 611, fully contacts with the water storage cavity 611 to become wet air, and then enters the storage compartment 12 through the humidifying air outlet 66 to humidify the storage compartment 12, so as to complete the humidifying process.

[0076] Among them, the humidifying fan 63 is arranged at the air inlet channel 652.

[0077] Further, the first air duct 511 of the turbulent flow air duct 51 and the turbulent flow air return opening 53 are formed on the housing 64. The humidifying air inlet 65 and the humidifying air outlet 66 are arranged on two opposite sides of the first air duct 511, so as to improve the integration degree of the overall structure of the refrigeration equipment, and has the advantages of compact structure and strong integrity.

[0078] Further, the humidifying assembly 6 further includes a water-absorbing sponge, a sterilization module and a water level sensor respectively arranged in the water storage cavity 611. Preferably, the water-absorbing sponge is a wavy water-absorbing and antibacterial sponge.

[0079] Further, 2 / 3 of the height direction of the water-absorbing sponge is placed in the water, and 1 / 3 of the height direction of the water-absorbing sponge is placed in the air above the water surface. Its function is to increase the contact area between water and air, and under the action of the humidifying fan 63, the storage compartment can be quickly humidified.

[0080] Further, the humidifying assembly 6 further includes shutter plates 68 respectively rotatably arranged at the humidifying air inlet 65 and the humidifying air outlet 66. The humidifying assembly 6 further includes a rotating shaft cooperatively arranged with the shutter plates 68, and the shutter plates 68 rotate around the rotating shaft. Preferably, the shutter plates 68 are light shutter plates 68 with relatively light mass.

[0081] Among them, when the humidifying fan 63 is started, the shutter plates 68 respectively rotate to open the humidifying air inlet 65 and the humidifying air outlet 66. Specifically, when the humidifying fan 63 is under the action of wind force, the shutter plates 68 rotate around the rotating shaft to open a certain opening of the humidifying air inlet 65 and the humidifying air outlet 66, and the humidifying air duct 62 is conducted to communicate the water storage cavity 611 with the storage compartment 12.

[0082] When the humidifying fan 63 is turned off, the baffles 68 rotate to close the humidifying air inlet 65 and the humidifying air outlet 66 respectively. Specifically, in the non-humidifying state, under the action of gravity, the baffles 68 are closely fitted with the humidifying air inlet 65 and the humidifying air outlet, switching the connection between the water storage cavity 611 and the storage compartment 12, and preventing the humidifying component 6 from affecting the humidity of the storage compartment 12.

[0083] Combined with Figure 7 、 Figure 8 As shown, further, the internal air path in the water storage box 61 can be designed as a "one" shape, a "U" shape, an "M" shape or other internal air paths. For the "one" shaped internal air path, there is no partition plate between the water storage boxes 61 to separate the humidifying air inlet space and the humidifying air outlet space.

[0084] Further, for the "U" shaped internal air path in the water storage box 61, specifically, the humidifying component 6 further includes a partition plate 69 with one end connected to the inner wall of the water storage box 61, and the humidifying air inlet 65 and the humidifying air outlet 66 are respectively arranged on opposite sides of the partition plate 69.

[0085] The humidifying air duct 62 includes an air inlet path extending from the humidifying air inlet 65 to the other end of the partition plate 69, and an air outlet path extending from the air inlet path to the humidifying air outlet 66. This is to extend the passing path of the air in the water storage cavity 611, so that the air has a longer contact time with water, improving the humidifying amount and the humidifying efficiency.

[0086] Further, the humidifying component 6 further includes a plurality of partition plates 69 respectively connected to the inner wall of the water storage box 61. The plurality of partition plates 69 are arranged between the humidifying air inlet 65 and the humidifying air outlet 66.

[0087] Among them, one of the adjacent two partition plates 69 is connected to one side inner wall of the described water storage box 61, and the other is connected to the other side inner wall of the described water storage box 61. The humidifying air duct 62 extends from the humidifying air inlet 65 along the partition plate 69 to the humidifying air outlet 66. Further extending the passing path of the air in the water storage cavity 611, so that the air has a longer contact time with water, improving the humidifying amount and the humidifying efficiency.

[0088] Further, the refrigeration device further includes a plate evaporator 3 arranged in the inner tank 11, and the partition wall is a heat conduction partition plate 2 on the side of the rear wall of the plate evaporator 3 facing away from the inner tank 11. The description of the heat conduction partition plate 2 has been detailed in the previous text and will not be elaborated here.

[0089] The plate evaporator 3 divides the space between the heat conduction partition plate 2 and the rear wall of the inner tank 11 into a cooling chamber 35 and a cold air circulation chamber 25. At least part of the heat conduction partition plate 2 is exposed in the storage compartment 12, and a fan 4 is arranged in the cooling chamber 35 or the cold air circulation chamber 25; among them, the dehumidifying port 26 is arranged on the part of the heat conduction partition plate 2 exposed in the storage compartment 12.

[0090] Among them, the cooling capacity of the plate evaporator 3 is radiated into the storage compartment 12 through the heat-conducting partition 2.

[0091] Further, an air return port 33 for the cold air to flow from the cold air circulation chamber 25 to the cooling chamber 35 is formed above the evaporation plate 31, and an air inlet 34 for the cold air to flow from the cooling chamber 35 to the cold air circulation chamber 25 is formed below the evaporation plate 31. The fan 4 is arranged at the position of the air inlet 34. The description of the circulation path between the cooling chamber 35 and the cold air circulation chamber 25 has been detailed in the foregoing text and will not be elaborated here.

[0092] Further, the dehumidification port 26 is arranged opposite to the air return port 33. The cold air in the cooling chamber 35 enters the cold air circulation chamber 25 from the air inlet 34 and flows upward, and then enters the cooling chamber 35 through the air return port 33 and flows downward to the air inlet 34. Thus, the cold air circulation between the cold air circulation chamber 25 and the cooling chamber 35 is completed. The dehumidification port 26 adds the cold air in the cooling chamber 35, thereby improving the convection between the air in the storage compartment 12 and the refrigeration cavity, and using the cold air in the cooling chamber 35 to dehumidify the storage compartment 12 to improve the dehumidification efficiency. The dehumidification port 26 is a grid-shaped opening structure. The size of the dehumidification port 26 is smaller than the size of the air return port 33.

[0093] To solve the above problems, the present embodiment also provides a control method.

[0094] A control method for a refrigeration device as described above includes,

[0095] respectively obtaining the actual humidity RH 实际 and the set humidity RH 设定 in the storage compartment 12, and adjusting the opening and closing degree of the dehumidification damper 27 and the dehumidification port 26 according to the difference between RH 实际 and RH 设定 .

[0096] Specifically, the difference between RH 实际 and RH 设定 reflects whether the storage compartment 12 needs dehumidification.

[0097] In the case of no need for dehumidification, there is no air flow exchange between the storage compartment 12 and the cooling chamber 35 to reduce the temperature and humidity fluctuations in the storage compartment 12. After the dehumidification damper 27 is opened, the storage compartment 12 and the cooling chamber 35 are connected. Due to the large temperature difference between the cooling chamber 35 and the storage compartment 12, there is a pressure difference. When the dehumidification damper 27 is opened, under the action of the pressure difference, the air in the storage compartment 12 and the refrigeration cavity forms natural convection, and the cold air in the cooling chamber 35 is used to dehumidify the storage compartment 12. Compared with multiple damper air inlets, a single air inlet can better control the air exchange rate and frequency between the two chambers, further reduce the temperature and humidity fluctuations, and ensure the reliability of the dehumidification damper 27.

[0098] Further,

[0099] After obtaining the actual humidity RH 实际 and the set humidity RH 设定 , calculate the difference RH 实际 between RH 设定 and RH 实际 , i.e., RH 设定 , and determine whether RH 实际 -RH 设定 satisfies RH 实际 -RH 设定 > 0;

[0100] When RH 实际 -RH 设定 > 0, set the dehumidification air door 27 to open the dehumidification port 26;

[0101] When RH 实际 -RH 设定 ≤ 0, set the dehumidification air door 27 to close the dehumidification port 26.

[0102] Specifically, RH 实际 -RH 设定 > 0 indicates that the humidity in the storage room 12 is high, and the dehumidification port 26 is opened by the dehumidification air door 27 to dehumidify the storage room 12.

[0103] RH 实际 -RH 设定 < 0 indicates that the storage room 12 does not need dehumidification.

[0104] Further,

[0105] When RH 实际 -RH 设定 > 0, determine whether RH 实际 -RH 设定 satisfies RH 实际 -RH 设定 > RH 预设1 ;

[0106] When RH 实际 -RH 设定 satisfies RH 实际 -RH 设定 > RH 预设1 at this time, set the dehumidification air door 27 to fully open the dehumidification port 26;

[0107] When RH 实际 -RH 设定 satisfies RH 实际 -RH 设定 ≤ RH 预设1 at this time, determine RH 实际 -RH设定 Whether it meets RH 实际 -RH 设定 >RH 预设2 , where 0 < RH 预设2 <RH 预设1 ;

[0108] When RH 实际 -RH 设定 meets RH 预设2 <RH 实际 -RH 设定 ≤RH 预设1 , set the dehumidification damper 27 to open 2 / 3 of the dehumidification port 26;

[0109] When RH 实际 -RH 设定 meets 0 < RH 实际 -RH 设定 ≤RH 预设2 , set the dehumidification damper 27 to open 1 / 3 of the dehumidification port 26.

[0110] Specifically, the opening degree of the dehumidification damper 27 is related to the actual humidity RH 实际 , the set humidity RH 设定 . The greater the difference between RH 实际 -RH 设定 , the greater the opening degree of the dehumidification damper 27 and the greater the opening of the dehumidification port 26, thereby improving the dehumidification amount and the dehumidification efficiency.

[0111] Preferably, the aforementioned RH 预设1 is 10%. The aforementioned RH 预设2 is 5%.

[0112] Specifically, when the actual humidity RH 实际 is more than 10% greater than the set humidity RH 设定 , the damper is fully open; when the actual humidity RH 实际 is between 5 - 10% greater than the set humidity RH 设定 , the dehumidification damper 27 opens 2 / 3; when the actual humidity RH 实际 is between 0 - 5% greater than the set humidity RH 设定 , the dehumidification damper 27 opens 1 / 3; in other states, the dehumidification damper 27 is closed, which has the advantage of finely adjusting the opening degree of the dehumidification damper 27.

[0113] Compared with the prior art, the refrigeration device provided by the present invention is provided with a dehumidification port 26 communicating the storage room 12 and the cooling room 35 on the partition wall between the storage room 12 and the cooling room 35, and a dehumidification air damper 27 for opening or closing the dehumidification port 26 is arranged at the dehumidification port 26. When dehumidification is not required, there is no air flow exchange between the storage room 12 and the cooling room 35 to reduce the temperature and humidity fluctuations in the storage room 12. When dehumidification is required, the dehumidification air damper 27 is opened to connect the storage room 12 and the cooling room 35, and the air in the storage room and the refrigeration cavity forms natural convection, and the cold air in the cooling room 35 is used to dehumidify the storage room 12. Compared with multiple air dampers and air inlets, a single air inlet can better control the air exchange rate and frequency between the two rooms, further reduce the temperature and humidity fluctuations and ensure the reliability of the dehumidification air damper 27. And through a water storage box 61 having a water storage cavity 611, a humidification air duct 62 connecting the water storage cavity 611 and the storage room 12, and a humidification fan 63 located in the humidification air duct 62, the humidification fan 63 is arranged in the humidification air duct 62 to enable air to flow between the water storage cavity 611 and the storage room 12, so as to humidify the storage room 12 through the humidified air. Through the joint cooperation of humidification and dehumidification, the humidity requirement of the storage room 12 can be met as soon as possible, the convenience of humidity regulation is enhanced, and it has the advantages of diverse humidity regulation, easy regulation, compact structure and high space utilization rate.
