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, which will change the quality of the red wine and cause the wine to volatilize through the cork, resulting in the "empty bottle" phenomenon. 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 the way of using a blower to assist blowing. This is often not much 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, the monitored compartment humidity will have a certain error from the actual humidity. If the humidification control strategy set originally is still used for humidification, the compartment humidity will be too low / high. Summary of the Invention

Detailed implementation manners

[0035] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0036] 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 cavity, where the cavity includes a component storage cavity 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 three storage spaces: upper, middle, and lower. 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 sucks 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, thereby achieving the effect of adjusting the humidity of the compartment 30.

[0037] See Figure 2 , Figure 2 is another schematic structural diagram of a wine cabinet 100 provided by an embodiment of the present invention. A compressor compartment 40 is provided at the bottom of the wine cabinet 100. A compressor 41 is provided in the compressor compartment 40. The compressor 41 is used to provide power for the refrigeration cycle of the wine cabinet 100.

[0038] See Figure 3 , Figure 3It is a schematic diagram of the distribution of humidity sensors in a wine cabinet provided in some embodiments. Since the middle compartment 30 in the wine cabinet in this embodiment is divided into three storage spaces: upper, middle, and lower, a first humidity sensor 51 is provided in each storage space. Since the storage spaces in the wine cabinet are interconnected, when calculating the real-time humidity of the compartment in the embodiments of the present invention, it is necessary to obtain the humidity detected by the three first humidity sensors 51 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 may also be provided with only one first humidity sensor 50. A second humidity sensor 52 is provided outside the cabinet 10. The number of the second humidity sensors 52 can be 1 or multiple, and can be set according to the actual placement environment of the wine cabinet. The second humidity sensor 52 is used to detect the real-time humidity of the environment. In addition, to ensure the temperature balance of each storage space, 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 the respective storage spaces of the compartment 30 through the refrigeration air outlet 34.

[0039] See Figure 4 , Figure 44 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.

[0040] See also Figure 5 , Figure 5 6 is a schematic diagram of the structure of a humidification module 60 in a wine cabinet provided in 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. 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 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 started and operates at regular intervals 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 to enable the controller to control the water pump 65 to stop working. The small water box 62 works in cooperation with auxiliary humidifying components such as a humidifying fiber and a humidifying fan. 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.

[0041] 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 decrease amplitude 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 increase amplitude is relatively high. The situation is opposite in winter. 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, and 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. If the wine cabinet is equipped with a damper, the damper can be closed during defrosting. At this time, most of the high-humidity gas can be blocked from flowing into the compartment, and the increase amplitude of the humidity is relatively low. 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 embodiments 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 achieve the humidity control of the wine cabinet.

[0042] In addition, when the cabinet door of the wine cabinet is opened, the gas with higher humidity outside the wine cabinet 100 will be mixed with the gas with lower humidity in the compartment 30, resulting in an increase in the humidity of the gas in the compartment 30. And since the external gas flowing into the compartment during the opening and closing of the wine cabinet door only enters when the user closes the door and there is no additional fan, the mixing process of the two gases takes a certain amount of time. And since the first humidity sensor 51 is fixedly arranged in the compartment 30, when the two gases are not fully mixed, the real-time humidity of the compartment detected by the first humidity sensor 51 may not accurately reflect the true humidity at this time. Therefore, in the embodiment of the present invention, by pre-establishing a humidity calculation model for the opening and closing of the wine cabinet door, the humidity value of the wine cabinet after experiencing an opening-closing cycle is calculated to reflect the true humidity of the compartment. It should be noted that the gas generated by the compressor refrigeration is introduced through the refrigeration fan 44 and can be fully mixed with the gas in the compartment 30; and, for the gas generated when the defrosting heater 43 works, if the air damper in the compartment 30 is closed, only a very small part of the gas carrying moisture generated by heating can flow into the compartment. Therefore, in the embodiment of the present invention, there is no need to establish a humidity calculation model for compressor refrigeration and defrosting heater defrosting.

[0043] Specifically, the controller is configured to: when detecting that the cabinet door is opened, obtain the real-time humidity of the compartment detected by the first humidity sensor; when detecting that the cabinet door is closed, record the opening duration of the cabinet door during this opening, and obtain the real-time humidity of the environment detected by the second humidity sensor; calculate the standard humidity of the compartment according to the real-time humidity of the compartment, the opening duration and the real-time humidity of the environment; when the standard humidity is less than a preset low humidity threshold, control the humidifying fan to operate at a preset first rotation speed. When the standard humidity is greater than or equal to the low humidity threshold and less than a preset medium humidity threshold, control the humidifying fan to operate at a preset second rotation speed; wherein, the first rotation speed is greater than the second rotation speed.

[0044] Exemplarily, refer to Figure 7 , Figure 7This 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 S19. When it is detected that the cabinet door is opened, the real-time humidity of the compartment detected by the first humidity sensor is immediately obtained. This real-time humidity of the compartment can reflect the humidity of the compartment before the wine cabinet door is opened. During the period when the user accesses items, no detection is performed, but the opening duration of the cabinet door needs to be accumulated. The timer can be started when it is detected that the cabinet door is opened. When it is detected that the cabinet door is closed, the wine cabinet has experienced an "open - close" cycle. At this time, the humidity in the compartment will change, but since the gas from outside the compartment and the gas inside the compartment have not been fully mixed, the real-time humidity of the compartment detected by the first humidity sensor cannot accurately reflect the true humidity. Therefore, at this time, when the cabinet door is closed, the real-time environmental humidity detected by the second humidity sensor is obtained, and the timing of the timer is stopped to obtain the opening duration of the cabinet door during this opening. Then, the standard humidity is calculated according to the real-time humidity of the compartment, the opening duration, and the real-time environmental humidity. When the standard humidity is lower than the low humidity threshold, it indicates that the humidity in the compartment is very low at this time and humidification is required immediately. The humidifying fan is controlled at the first speed to achieve the purpose of humidifying as soon as possible. When the standard humidity is greater than or equal to the low humidity threshold and less than the preset medium humidity threshold, it indicates that the humidity in the compartment is not very low at this time, and the humidifying fan can be controlled to operate at the second speed.

[0045] It should be noted that the low humidity threshold and the medium humidity threshold can be set according to empirical values. For example, the low humidity threshold is set to 55%, and the medium humidity threshold is set to 60%, or other values can be set. The present invention does not make specific limitations on this. The first speed is the high speed of the humidifying fan. For example, the first speed is 1.5 PMW, and the second speed is the low speed of the humidifying fan. For example, the first speed is 1.2 PMW. Or, the first speed and the second speed can be other values. The present invention does not make specific limitations on this. It can be understood that the higher the speed of the humidifying fan, the higher its humidifying efficiency, and thus the higher the humidity growth rate in the compartment 30.

[0046] Further, calculating the standard humidity of the compartment according to the real-time humidity of the compartment, the opening duration, and the real-time environmental humidity includes: calculating the humidity difference between the real-time humidity of the compartment and the real-time environmental humidity; calculating the product of the humidity difference, the opening duration, and a preset humidity coefficient, and taking the product as the humidity adjustment value; taking the sum of the real-time humidity of the compartment and the humidity adjustment value as the standard humidity.

[0047] Exemplarily, the standard humidity is calculated according to the following humidity calculation model:

[0048] D = Dj + (Dh - Dj) * t * k;

[0049] Wherein, D is the standard humidity; Dj is the real-time humidity of the compartment; Dh is the real-time environmental humidity; t is the opening duration; and k is the humidity coefficient, which can be measured through experiments.

[0050] Specifically, after starting the humidifying fan, the controller is further configured to: obtain the real-time humidity of the compartment detected by the first humidity sensor; when the real-time humidity of the compartment reaches a preset medium humidity threshold, obtain the action state of the cabinet door, the working 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 humidifying fan to maintain the current rotation speed until the real-time humidity of the compartment reaches a preset high humidity threshold, and then control the humidifying fan 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 humidifying fan to stop running.

[0051] Exemplarily, refer 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 or S19, it is further configured to execute steps S20 to S28. After starting the humidifying fan, the humidity in the compartment 30 will gradually increase at this time. When the real-time humidity reaches the medium humidity threshold, start monitoring the working states of the compressor and the defrosting heater and the action state of the cabinet door. 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 the situations of "the humidity in the compartment decreases due to the refrigeration operation of the compressor", "the humidity in the compartment increases due to the defrosting operation of the defrosting heater", and "the humidity in the compartment increases due to the opening of the cabinet door" will not occur at this time. At this time, only by starting the humidifying module to increase the humidity in the compartment, so control the humidifying module to keep running until the real-time humidity reaches a preset high humidity threshold, and then control the humidifying module to stop running. At this time, the highest humidity required for the compartment has been reached. As the storage time increases, the items stored in the compartment (such as wine) will consume the humidity in the compartment, and during the refrigeration process of the compressor, the humidity will also decrease. Therefore, humidifying to the highest humidity is to ensure that the humidity in the compartment will not be too low 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 on this.

[0052] Exemplarily, during the process that the real-time humidity increases from the medium humidity threshold to the high humidity threshold, monitor the action state of the cabinet door, and 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 in 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 reduction in the humidity in the compartment caused by the compressor during refrigeration is very small, and the real-time humidity in the compartment at this time is not very low 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 in 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 reducing the temperature in 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 operating 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.

[0053] Specifically, the controller is further configured to: when the standard humidity is greater than or equal to a preset medium humidity threshold and less than a preset high humidity threshold, obtain the action state of the cabinet door, and 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 fan to operate until the real-time humidity in the compartment reaches the high humidity threshold, and then control the humidification fan to stop operating; 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 fan to stop operating.

[0054] Exemplarily, refer to Figure 9 , Figure 9 FIG. is the third working flowchart of the controller in the wine cabinet provided by the embodiment of the present invention. After the controller executes step S15, it is further configured to execute steps S31 to S38. The processes of steps S31 to S38 can refer to the processes of the above steps S22 to S28 and will not be elaborated here. At this time, the rotational speed of the humidification fan during the operation of step S36 can be the first rotational speed or the second rotational speed.

[0055] Compared with the prior art, the wine cabinet disclosed in the present invention uses an independent humidification module to humidify the compartments of the wine cabinet and monitors the opening state of the cabinet door during the humidification process. Since the opening of the cabinet door will cause the gas outside the wine cabinet to flow into the wine cabinet, resulting in a change in the humidity of the compartment. During the process of the user opening the cabinet door, the humidity state of the compartment is monitored by a humidity sensor, and the influence of the humidity of the wine cabinet environment on the humidity of the compartment is judged by the opening time and the humidity difference between the inside and outside of the wine cabinet, and a humidification strategy with different humidification speeds is formulated. At the same time, two factors, namely the working state of the defrost heater and the action state of the cabinet door, are introduced, and the corresponding humidification strategy can be selected according to the working states of the compressor and the defrost heater and the action state of the cabinet door, so as to maintain the storage humidity in the wine cabinet within a suitable humidity range.

[0059] S3. Calculate the standard humidity of the compartment according to the real-time humidity of the compartment, the opening duration, and the real-time environmental humidity;

[0060] S4. When the standard humidity is less than a preset low humidity threshold, control the humidification fan in the refrigeration device to operate at a preset first speed.

[0061] Specifically, the method further includes: when the standard humidity is greater than or equal to the low humidity threshold and less than a preset medium humidity threshold, control the humidification fan to operate at a preset second speed; wherein, the first speed is greater than the second speed.

[0063] Specifically, the method further includes: 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, controlling the humidifying fan to stop operating.

[0064] Specifically, calculating the standard humidity of the compartment according to the real-time humidity of the compartment, the opening duration, and the real-time humidity of the environment includes: calculating the humidity difference between the real-time humidity of the compartment and the real-time humidity of the environment; calculating the product of the humidity difference, the opening duration, and a preset humidity coefficient, and using the product as the humidity adjustment value; using the sum of the real-time humidity of the compartment and the humidity adjustment value as the standard humidity.

Since the opening of the cabinet door will cause the gas outside the refrigeration device to flow into the refrigeration device, resulting in a change in the humidity of the compartment, during the process of the user opening the cabinet door, the humidity state of the compartment is monitored by a humidity sensor, and the influence of the environmental humidity of the refrigeration device on the humidity of the compartment is judged based on the opening time and the humidity difference inside and outside the refrigeration device, and a humidification strategy with different humidification speeds is formulated. At the same time, two factors, namely the working state of the defrosting heater and the action state of the cabinet door, are introduced, and 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 as to maintain the storage humidity in the refrigeration device within a suitable humidity range.
