Abstract

The corresponding humidification strategy can be selected according to the working states of the compressor and the defrosting heater and the action state of the cabinet door, so that the storage humidity in the wine cabinet is maintained within a proper humidity range.

Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration equipment, and particularly to a wine cabinet and a humidity control method for refrigeration equipment. Background Art

[0002] With the continuous improvement of people's living standards, wine cabinets have entered ordinary families as household appliances. Most of the wine cabinets on the market are single-temperature zone wine cabinets, which usually can only maintain a constant temperature state. However, for the storage of some special wines, humidity and temperature control are equally important. For example, the ideal humidity for storing wine is between 60% and 70%. Insufficient humidity in the wine cabinet will cause the cork to lose elasticity and unable to seal the bottle mouth, resulting in the invasion of outside air, changing the quality of the red wine, and causing the wine to volatilize through the cork, resulting in the phenomenon of "empty bottle". In order to achieve humidity control in the wine cabinet, currently, most wine cabinets use the method of setting a humidifying water box at the bottom of the cabinet to humidify the wine cabinet. The humid air enters the wine cabinet through the natural evaporation of the water in the water box or by using a blower to assist in blowing. This is often not overly related to the working state of the wine cabinet itself, or only roughly adjusts the humidity in the wine cabinet compartment by controlling the defrosting and operation of the refrigeration blower of the wine cabinet, and cannot accurately and permanently maintain the compartment humidity within a small fluctuation range.

[0003] In addition, WO2021103520A1 and WO2021103521A1 describe a method for controlling the start and stop of a compressor and a blower according to the temperature and humidity in a refrigerator compartment. Although it can achieve constant temperature and humidity control in the compartment, it is necessary to adjust the working modes of the compressor and the blower, which will affect the refrigeration efficiency of the refrigerator. The prior art also describes a humidification control strategy with corresponding gradients according to the current humidity of the compartment after the refrigeration equipment compartment is opened and then closed. However, after the refrigeration equipment compartment is opened and then closed, it takes some time for the gas state in the compartment to stabilize. At this time, there will be a certain error between the monitored compartment humidity and the actual humidity. If the humidification control strategy set originally is still used for humidification, the phenomenon of too low / high humidity in the compartment will occur. Summary of the Invention

Specific embodiments

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] See Figure 1 , Figure 1 is a schematic structural diagram of a wine cabinet 100 provided by an embodiment of the present invention. The wine cabinet 100 described in the embodiment of the present invention has an approximate cuboid shape. The wine cabinet 100 includes a cabinet body 10 that defines a storage space and a cabinet door 20 provided at the opening of the cabinet body 10. The cabinet body 10 is provided with a chamber, where the chamber includes a component storage chamber for placing components in the wine cabinet 100, such as a compressor compartment, a fan compartment, etc., and also includes a compartment 30 for storing items. In the wine cabinet 100 shown in the embodiment of the present invention, the compartment 30 is provided with two shelves 31. The two shelves 31 form upper, middle, and lower storage spaces. There are a humidification air inlet 32 and a humidification air outlet 33 on the shelf 31 for communicating the compartment space with the humidification module. The humidification module draws in the air in the compartment 30 through the humidification air inlet 32. After being humidified by the humidification module, the high-humidity air then enters the compartment 30 from the humidification air outlet 33, so as to achieve the effect of adjusting the humidity of the compartment 30.

[0041] See Figure 2 , Figure 2 is another schematic structural diagram of a wine cabinet 100 provided by an embodiment of the present invention. The bottom of the wine cabinet 100 is provided with a compressor compartment 40. The compressor compartment 40 is provided with a compressor 41. The compressor 41 is used to provide power for the refrigeration cycle of the wine cabinet 100.

[0042] See Figure 3 , Figure 3: is a schematic diagram of the distribution of humidity sensors 50 in a wine cabinet provided in some embodiments. Since the middle chamber 30 of the wine cabinet in this embodiment is divided into three storage spaces: upper, middle and lower, a humidity sensor 50 is set in each storage space. Since the storage spaces in the wine cabinet are interconnected, when the embodiment of the present invention subsequently calculates the real-time humidity of the compartment, it is necessary to obtain the humidity detected by the three humidity sensors 50, and then take the average value as the real-time humidity of the compartment 30. In some embodiments, a wine cabinet with a single refrigeration space can also be provided with only one first humidity sensor 50. In order to ensure that the temperature of each storage space is balanced, a refrigeration air outlet 34 is provided in each storage space, and the cold air generated by the refrigeration system in the wine cabinet 100 is introduced into each storage space of the compartment 30 through the refrigeration air outlet 34.

[0043] See also Figure 4 , Figure 4 4 is a schematic diagram of the structure of the refrigeration system in the wine cabinet provided by an embodiment of the present invention. In addition to the above-mentioned compressor 41, the refrigeration system also includes an evaporator 42, a refrigeration fan 44, a condenser, a gas-liquid separator and a capillary tube, etc., wherein, when the contacts of the thermostat are turned on, the compressor 41 starts to work, and the low-temperature and low-pressure refrigerant is sucked into the compressor 41, compressed into a high-temperature and high-pressure superheated gas in the cylinder of the compressor 41, and then discharged to the condenser; the high-temperature and high-pressure refrigerant gas dissipates heat through the condenser, and the temperature continues to drop, and is gradually cooled to a saturated vapor at room temperature and high pressure, and is further cooled to a saturated liquid, and the temperature no longer drops. The temperature at this time is called the condensation temperature, and the refrigerant is in the entire refrigeration The pressure during the condensation process remains almost unchanged; the condensed refrigerant saturated liquid flows into the capillary tube after being filtered by the drying filter to remove moisture and impurities, and the refrigerant is throttled and depressurized through the capillary tube, and the refrigerant becomes wet steam at room temperature and low pressure; the wet steam at room temperature and low pressure begins to absorb heat and vaporize in the evaporator 42, which not only reduces the temperature of the evaporator 42 and its surroundings, but also turns the refrigerant into a low-temperature, low-pressure gas. The refrigerant coming out of the evaporator 42 passes through the gas-liquid separator and returns to the compressor 41 again, repeating the above process, transferring the heat in the wine cabinet to the air outside the cabinet, and the cold air generated by the heat exchange of the evaporator is fed into the compartment 30 after the action of the refrigeration fan 44, achieving the purpose of refrigeration. In addition, a temperature sensor 45 is provided on the upper part of the evaporator 42, and a defrost heater 43 is provided at the bottom of the evaporator 42. The defrost heater 43 starts to melt the ice on the evaporator 42 at a fixed time, performs the defrost operation, and prevents the evaporator 42 from frosting. The temperature sensor 45 is used to monitor the defrost temperature. After the defrost heater is started, if it is detected that the defrost temperature reaches the set value, defrosting is stopped and the wine cabinet resumes refrigeration.

[0044] See also Figure 5 , Figure 5It is a schematic structural diagram of the humidification module 60 in the wine cabinet provided by an embodiment of the present invention. The humidification module 60 includes a large water box 61, a small water box 62, a liquid level sensor 63, a water pipe 64, a water pump 65, a water valve 66, and a water injection port 67. Among them, see Figure 6 , the large water box 61 is arranged at the bottom of the wine cabinet 100, the water valve 66 is arranged on the external water pipeline to control the external water source to inject water into the large water box 61. In addition, a water injection port 67 is also arranged at the top of the large water box 61, and the user can manually inject water into the large water box 61 through the water injection port 67. The small water box 62 is arranged in the shelf 31 of the compartment 30 and is connected to the large water box 61 through a water pipe 64. A water pump 65 is arranged on the water pipe 64. The water pump 65 is turned on and operates every once in a while to pump the water in the large water box 61 into the small water box 62. A liquid level sensor 63 is arranged on the small water box 62. When the water level in the small water box 62 reaches a certain height, the liquid level sensor 63 outputs a signal to the controller of the wine cabinet 100, so that the controller controls the water pump 65 to stop working. The small water box 62 works together with auxiliary humidification components such as humidifying fibers and humidifying fans. When the humidifying fan is started, the water in the small water box 62 is consumed to adjust the humidity of the compartment 30, and when the humidifying fan is turned off, the humidification stops.

[0045] It should be noted that when the wine cabinet 100 needs to refrigerate, the compressor 41 operates. At this time, the cold air generated after the heat exchange of the evaporator 42 will flow into the compartment 30 through the refrigeration air outlet 34. Since the temperature inside the compartment decreases, the water molecules in the air condense and the air humidity becomes smaller. Therefore, the humidity of the compartment 30 will decrease during the refrigeration process, but the amplitude of the humidity decrease is relatively low; since the wine cabinet 100 is generally used in summer (high temperature), and the environmental humidity in summer is generally high. Therefore, when the user opens the cabinet door 20 of the wine cabinet 100, the gas with higher humidity outside the wine cabinet 100 will be mixed with the gas with lower humidity inside the compartment 30, resulting in an increase in the humidity of the gas inside the compartment 30, and the amplitude of the humidity increase is average; when the wine cabinet 100 needs to defrost, the defrost heater 43 is started. Since during the heating process of the defrost heater 43, the frost layer (ice layer) condensed on the evaporator 42 will melt due to high temperature, a large amount of gas carrying moisture will be generated during this process, and a part of this high-humidity gas will flow into the compartment 30 along with the refrigeration air outlet 34, resulting in an increase in the humidity of the compartment 30, and the amplitude of the humidity increase is relatively high. It can be seen that the operation of the compressor for refrigerating the compartment, the start of the defrost heater to perform the defrost operation, and the opening of the cabinet door to allow the outside air to flow into the compartment will all cause changes in the humidity of the compartment. Therefore, in the embodiment of the present invention, factors such as the working state of the wine cabinet and the action state of the cabinet door are considered to achieve the humidity control of the wine cabinet.

[0046] Specifically, the controller is configured to: when the wine cabinet is powered on for non-first time, obtain the real-time humidity detected by the humidity sensor; when the real-time humidity is lower than a preset low humidity threshold, obtain the working state of the defrost heater and the action state of the cabinet door; when the defrost heater is in a shutdown state and the cabinet door is in a closed state, start the humidification module; when the defrost heater is in an operating state or the cabinet door is in an open state, control the humidification module to stop operating.

[0047] Exemplarily, referring to Figure 7 , Figure 7 is the first working flowchart of the controller in the wine cabinet provided by the embodiment of the present invention. The controller is configured to execute steps S11 to S18. When it is detected that the wine cabinet is powered on for non-first time, it means that the wine cabinet has been running for a period of time, and at this time, the temperature and humidity are relatively balanced. The low humidity threshold can be set according to empirical values, such as set to 55%, or can be set to other values, and the present invention does not make specific limitations thereto. Obtain the real-time humidity of the compartment detected by the humidity sensor. When the real-time humidity is lower than the preset low humidity threshold, it means that the humidity of the compartment is low at this time and humidification operation is required. However, at this time, the humidification module (start the humidification fan) is not directly started, but further obtain the working state of the defrost heater and the action state of the cabinet door. When the defrost heater is in a shutdown state and the cabinet door is in a closed state, it means that at this time, there will be no situations of "the humidity of the compartment increases due to the defrost heater performing defrost operation" and "the humidity of the compartment increases due to opening the cabinet door", and only by starting the humidification module to increase the humidity of the compartment. During the process of starting the humidification module, the working state of the defrost heater and the action state of the cabinet door should also be monitored all the time. If it is detected that the defrost heater is in an operating state or the cabinet door is in an open state, at this time, the humidity will increase, and the humidification module can be controlled to stop operating (turn off the humidification fan) to avoid excessive humidity in the compartment and save electric energy. In addition, when the real-time humidity is lower than the low humidity threshold, since the humidity is already very low at this time, it is necessary to give priority to ensuring the humidity balance of the compartment. Therefore, regardless of whether the compressor is in a shutdown state or an operating state, the humidification module needs to be started.

[0048] Specifically, the controller is further configured to: after starting the humidification module, if the real-time humidity reaches a preset medium humidity threshold, obtain the action state of the cabinet door, the operating states of the compressor and the defrosting heater; when the compressor is in a stopped state, the defrosting heater is in a stopped state, and the cabinet door is in a closed state, control the humidification module to keep running; until the real-time humidity reaches a preset high humidity threshold, control the humidification module to stop running. When the compressor is in an operating state, the defrosting heater is in an operating state, or the cabinet door is in an open state, control the humidification module to stop running.

[0049] Exemplarily, referring to Figure 8 , Figure 8 FIG. is the second working flowchart of the controller in the wine cabinet provided by the embodiment of the present invention. After the controller executes step S17, it is further configured to execute steps S19 to S25. The medium humidity threshold can be set according to empirical values, such as set to 70%, or can be set to other values, and the present invention does not make specific limitations thereto. After starting the humidification module, the humidity in the time chamber 30 will gradually increase. When the real-time humidity reaches the medium humidity threshold, in addition to monitoring the operating state of the defrosting heater and the action state of the cabinet door, it is also necessary to monitor the operating state of the compressor. If at this time the compressor is in a stopped state, the defrosting heater is in a stopped state, and the cabinet door is in a closed state, it means that at this time, the situations of "the humidity in the chamber decreases due to the refrigeration operation of the compressor", "the humidity in the chamber increases due to the defrosting operation of the defrosting heater", and "the humidity in the chamber increases due to the opening of the cabinet door" will not occur. At this time, only by starting the humidification module to increase the humidity in the chamber, so control the humidification module to keep running until the real-time humidity reaches a preset high humidity threshold, and then control the humidification module to stop running. At this time, the highest humidity required by the chamber has been reached. As the storage time increases, the items stored in the chamber (such as wine) will consume the humidity in the chamber, and during the refrigeration process of the compressor, the humidity will also be reduced. Therefore, humidifying to the highest humidity is to ensure that the humidity in the chamber will not be too low even when the humidity decreases subsequently. The high humidity threshold can be set according to empirical values, such as set to 75%, or can be set to other values, and the present invention does not make specific limitations thereto.

[0050] Exemplarily, during the process that the real-time humidity increases from the medium humidity threshold to the high humidity threshold, monitor the operation state of the cabinet door, the operating states of the compressor and the defrost heater. When the compressor is in the operating state, the defrost heater is in the operating state, or the cabinet door is in the open state, control the humidification module to stop operating. At this time, start the defrost operation by means of the defrost heater or open the cabinet door to allow outdoor air to flow into the compartment, so as to increase the humidity of the compartment. The humidification module stops operating (turn off the humidification fan), which can avoid excessive humidity in the compartment and save electrical energy. In addition, since the amplitude of the decrease in the humidity of the compartment caused by the compressor during refrigeration is very small, and the real-time humidity of the compartment is not very low at this time and is already greater than the medium humidity threshold, the purpose of stopping the humidification module at this time is to ensure that the temperature of the compartment reaches equilibrium first. If the humidification module is started during the refrigeration process, at this time, the cold air in the compartment needs to pass through the humidification inlet, the small water box, the humidification fiber and the humidification outlet for humidification. The temperature of the humidified gas output from the humidification outlet is much higher than the temperature of the cold air output after the heat exchange of the evaporator. As a result, the process of cooling the compartment is slow, which will increase the operating duration of the compressor and lead to an increase in energy consumption. Therefore, in the embodiment of the present invention, when it is detected that the compressor is running and the real-time humidity is between the medium humidity threshold and the high humidity threshold, it is necessary to control the humidification module to stop operating.

[0051] Specifically, the controller is further configured to: when the real-time humidity is greater than or equal to the low humidity threshold and less than a preset medium humidity threshold, obtain the operation state of the cabinet door, the operating states of the compressor and the defrost heater; when the compressor is in the shutdown state, the defrost heater is in the shutdown state, and the cabinet door is in the closed state, control the humidification module to keep running; until the real-time humidity reaches the preset high humidity threshold, control the humidification module to stop operating.

[0052] Exemplarily, refer to Figure 9 , Figure 9This is the third working flowchart of the controller in the wine cabinet provided by the embodiments of the present invention. After the controller executes step S12, it is further configured to execute steps S31 to S37. When it is detected that the wine cabinet is not powered on for the first time, it means that the wine cabinet has been running for a period of time, and at this time, the temperature and humidity are relatively balanced. Obtain the real-time humidity of the compartment detected by the humidity sensor. When the real-time humidity is greater than or equal to the low humidity threshold and less than the medium humidity threshold, it means that the humidity of the compartment is relatively low at this time and humidification operation is required. If at this time the compressor is in the shutdown state, the defrost heater is in the shutdown state, and the cabinet door is in the closed state, it means that the situations of "the humidity of the compartment decreases due to the refrigeration operation of the compressor", "the humidity of the compartment increases due to the defrost operation of the defrost heater", and "the humidity of the compartment increases due to the opening of the cabinet door" will not occur at this time. The humidity of the compartment can be increased only by starting the humidification module. Therefore, control the humidification module to keep running until the real-time humidity reaches the preset high humidity threshold, and then control the humidification module to stop running. During the process of the real-time humidity increasing from the medium humidity threshold to the high humidity threshold, monitor the action state of the cabinet door, the working states of the compressor and the defrost heater. When the compressor is in the running state, the defrost heater is in the running state, or the cabinet door is in the open state, control the humidification module to stop running. At this time, by means of the defrost heater starting to perform the defrost operation or the cabinet door being opened and the outdoor air flowing into the compartment, the humidity of the compartment is increased. The humidification module stops running (turn off the humidifying fan), which can avoid the humidity of the compartment being too high and save electric energy. In addition, since the amplitude of the humidity reduction in the compartment caused by the refrigeration of the compressor is very small, and the real-time humidity of the compartment at this time is not very low and is already greater than the low humidity threshold, the purpose of stopping the humidification module at this time is to ensure that the temperature of the compartment reaches equilibrium first. If the humidification module is started during the refrigeration process, the cold air in the compartment needs to pass through the humidification inlet, the small water box, the humidification fiber and the humidification outlet for humidification. The temperature of the humidified gas output from the humidification outlet is much higher than the temperature of the cold air output after the heat exchange of the evaporator. As a result, the temperature reduction process of the compartment is slow, which will increase the running time of the compressor and lead to an increase in energy consumption. Therefore, in the embodiments of the present invention, when it is detected that the compressor is running and the real-time humidity is between the low humidity threshold and the high humidity threshold, it is necessary to control the humidification module to stop running.

[0053] Specifically, the controller is further configured to: when the wine cabinet is powered on for the first time, start the humidification module; obtain the real-time humidity detected by the humidity sensor; when the real-time humidity reaches the preset high humidity threshold, control the humidification module to stop running.

[0054] Exemplarily, refer to Figure 10 , Figure 10It is the fourth working flowchart of the controller in the wine cabinet provided by the embodiment of the present invention. After the controller finishes executing step S11, it is further configured to execute S41-S45. Since the wine cabinet is used for the first time and its temperature and humidity are not balanced, after the wine cabinet is powered on, the humidification module is directly started for humidification. At this time, it is not necessary to monitor the working states of the compressor, the defrost heater, and the movement state of the cabinet door. It is necessary to make the compartment reach the optimal temperature and humidity conditions as soon as possible, and then control the humidification module to stop running. Subsequently, the working processes of steps S11-S25 or steps S31-S35 are executed.

[0055] Furthermore, a dehumidification module is also provided in the wine cabinet. Considering that the start of the defrost heater to perform defrosting operations and the opening of the cabinet door causing outdoor air to flow into the compartment will both cause changes in the humidity of the compartment. If the humidity continues to be too high all the time, such as when it is detected that the real-time humidity is greater than the high humidity threshold and the continuous duration is greater than the preset duration threshold (such as 1h), at this time, the dehumidification module is started to start dehumidification until the real-time humidity is lower than the high humidity threshold, and then the dehumidification module is turned off. The dehumidification module can adopt a functional module in the prior art that has an initial function and can be controlled by the controller to start / stop dehumidification, and will not be elaborated here.

[0056] Compared with the prior art, the wine cabinet disclosed by the present invention uses an independent humidification module to humidify the compartment of the wine cabinet, and monitors the working states of the compressor, the defrost heater, and the movement state of the cabinet door in the process of humidification. Since the operation of the compressor for refrigerating the compartment, the start of the defrost heater to perform defrosting operations, and the opening of the cabinet door causing outdoor air to flow into the compartment will all cause changes in the humidity of the compartment, therefore, in the embodiment of the present invention, factors such as the working state of the wine cabinet and the movement state of the cabinet door are considered to realize the humidity control of the wine cabinet, and corresponding humidification strategies can be selected according to the working states of the compressor, the defrost heater, and the movement state of the cabinet door, so as to maintain the storage humidity in the wine cabinet within a suitable humidity range.

[0057] See Figure 11 , Figure 11 is the flowchart of a humidity control method for a refrigeration device provided by the embodiment of the present invention. The humidity control method for the refrigeration device is implemented by the controller in the refrigeration device. The humidity control method for the refrigeration device includes:

[0058] S1. When the refrigeration device is not powered on for the first time, obtain the real-time humidity in the middle compartment of the refrigeration device;

[0059] S2. When the real-time humidity is lower than the preset low humidity threshold, obtain the working state of the defrost heater and the movement state of the cabinet door in the refrigeration device;

[0060] S3. When the defrosting heater is in the shutdown state and the cabinet door is in the closed state, start the humidification module;

[0061] S4. When the defrosting heater is in the running state or the cabinet door is in the open state, control the humidification module to stop running.

[0062] Specifically, the method further includes: after starting the humidification module, if the real-time humidity reaches the preset medium humidity threshold, obtain the action state of the cabinet door, and the working states of the compressor and the defrosting heater;

[0063] When the compressor is in the shutdown state, the defrosting heater is in the shutdown state, and the cabinet door is in the closed state, control the humidification module to keep running; until the real-time humidity reaches the preset high humidity threshold, control the humidification module to stop running.

[0064] Specifically, after obtaining the action state of the cabinet door, and the working states of the compressor and the defrosting heater, the method further includes: when the compressor is in the running state, the defrosting heater is in the running state, or the cabinet door is in the open state, control the humidification module to stop running.

[0065] Specifically, the method further includes: when the real-time humidity is greater than or equal to the low humidity threshold and less than the preset medium humidity threshold, obtain the action state of the cabinet door, and the working states of the compressor and the defrosting heater; when the compressor is in the shutdown state, the defrosting heater is in the shutdown state, and the cabinet door is in the closed state, control the humidification module to keep running; until the real-time humidity reaches the preset high humidity threshold, control the humidification module to stop running.

[0066] Specifically, the method further includes: when the refrigeration device is powered on for the first time, start the humidification module; when the real-time humidity of the compartment reaches the preset high humidity threshold, control the humidification module to stop running.

[0067] It should be noted that the specific working process in the humidity control method of the refrigeration device described in the embodiments of the present invention may refer to the working process of the controller in the wine cabinet described in the above embodiments, and will not be elaborated here.

[0068] Compared with the prior art, the humidity control method for a refrigeration device disclosed in the present invention uses an independent humidification module to humidify the compartments of the refrigeration device, and monitors the operating states of the compressor and defrost heater in the refrigeration device and the movement state of the cabinet door during the humidification process. Since the operation of the compressor for compartment refrigeration, the start of the defrost heater to perform defrost operation, and the opening of the cabinet door to allow outdoor air to enter the compartment will all cause changes in the humidity of the compartment, the embodiments of the present invention consider these factors such as the operating state of the refrigeration device and the movement state of the cabinet door to achieve the humidity control of the refrigeration device, and can select corresponding humidification strategies according to the operating states of the compressor, defrost heater, and the movement state of the cabinet door, so as to maintain the storage humidity in the refrigeration device within a suitable humidity range.

[0069] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art in the technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
