The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0026] In the description of the present invention, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood as not including the number itself, and "above", "below", "within" etc. are understood as including the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0028] In the related art, the ambient temperature of the refrigeration equipment is high (for example, the external environment is above 35°C), while the internal temperature setting is relatively low (for example, 5°C), so the compressor needs to be turned on frequently or for a long time for cooling. However, the air-cooled refrigeration method will cause moisture to condense, which will also cause the humidity in the refrigeration equipment to drop significantly. When the refrigeration equipment needs to maintain a high humidity (for example, the humidity requirement is 80%), the humidification component in the related art is difficult to meet the humidification requirements, so the humidification efficiency needs to be improved.

[0029] Refer to the following Figures 1 to 5 As shown, it is explained how the humidifying component 100 and the refrigeration device according to the embodiment of the present invention solve the above-mentioned problems.

[0030] Reference Figure 1 and Figure 2 As shown, it can be understood that the humidification component 100 of the first embodiment of the present invention includes a water storage member 410 and a first fan 401. Liquid can be stored in the water storage member 410. The first fan 401 generates a conveying airflow. The air outlet of the first fan 401 faces the water storage member 410, so that the conveying airflow passes through the water storage member 410 to take away the moisture in the water storage member 410, thereby forming high-humidity air, which enters the target space and mixes with the air in the target space to increase the humidity of the target space.

[0031] It is understandable that, due to the limited space in the refrigeration equipment, in order not to affect the use of space, the installation space for placing the humidification component 100 is relatively small, resulting in limited power of the first fan 401. When faced with a high temperature external environment and low temperature storage requirements, resulting in increased water loss, and also requiring high humidity storage conditions, the humidification efficiency is low with only the combination of the first fan 401 and the water storage member 410, and it is difficult to meet the above requirements.

[0032] Reference Figure 1 and Figure 2 As shown, it can be understood that the humidification component 100 of the first embodiment of the present invention further includes an ultrasonic generator 406 and a water guide 407, the water guide 407 connects the ultrasonic generator 406 and the water storage member 410 to transfer the moisture of the water storage member 410 to the ultrasonic generator 406, and the water guide 407 can be a device with a water guide function such as a cotton swab. The ultrasonic generator 406 vibrates to emit a waveform to convert liquid water into tiny water mist particles. These tiny water mist particles are then blown into the air by the first fan 401, thereby achieving a humidification effect.

[0033] Specifically, the humidification component 100 includes a shell 402 and a cover plate 408. The shell 402 is provided with a first mounting groove 403 and a second mounting groove 404. A partition bar 405 is provided between the first mounting groove 403 and the second mounting groove 404. The partition bar 405 is located at the bottom of the first mounting groove 403 and the second mounting groove 404, so that the bottoms of the first mounting groove 403 and the second mounting groove 404 cannot be connected, while the tops of the first mounting groove 403 and the second mounting groove 404 can be connected. The first fan 401 is arranged in the first mounting groove 403, and liquid is stored in the second mounting groove 404 to form a water storage member 410. The airflow blown out by the first fan 401 enters the second mounting groove 404 from above the partition bar 405, contacts with the liquid and takes away the moisture of the liquid, thereby forming high-humidity air. The cover plate 408 is connected to the shell 402 and is located above the first mounting groove 403 and the second mounting groove 404. There is a gap between the cover plate 408 and the liquid surface to form a humidification channel. The cover plate 408 is provided with a first air outlet 104, and high humidity air flows out from the first air outlet 104. The first fan 401 is powered on, and after the relatively dry air is sucked into the first fan 401 and accelerated, the dry air quickly passes through the liquid surface, and the air with high humidity on the liquid surface is quickly taken away from the first air outlet 104 on the cover plate 408 to the target space to mix with the air, thereby increasing the relative humidity of the target space. When the ultrasonic generator 406 is turned on, the air humidity can be further increased, and under the action of the conveying airflow blown out by the first fan 401, it can be mixed with the air in the target space faster, thereby improving the humidification efficiency.

[0034] It is understandable that the ultrasonic generator 406 is mounted on the cover plate 408, and the cover plate 408 is provided with a humidification hole 409. The water mist particles generated by the vibration of the ultrasonic generator 406 can enter the target space from the humidification hole 409, shortening the conveying distance. And the humidification hole 409 is close to the first air outlet 104, and the airflow of the first fan 401 can be used to accelerate the mixing rate of the water mist particles and the air in the target space. Since the ultrasonic generator 406 is integrated on the cover plate 408, the occupied space of the humidification component 100 can be reduced. That is, the ultrasonic generator 406 and the water guide 407 are arranged between the cover plate 408 and the housing 402, and the original space of the humidification component 100 is utilized. Under the premise of not increasing the occupied space of the humidification component 100, the overall humidification efficiency of the humidification component 100 is increased, which can better meet the requirements of setting low temperature and high humidity for refrigeration equipment at high ambient temperature.

[0035] Reference Figure 1 and Figure 2As shown, it can be understood that the cover plate 408 includes an air outlet area, the first air outlet 104 is arranged in the air outlet area, the first fan 401 is located on one side of the air outlet area, and the ultrasonic generator 406 is located on the other side of the air outlet area, that is, the conveying airflow blown out by the first fan 401 is first blown out through the first air outlet 104, and will not be blocked by the ultrasonic generator 406 and the water guide member 407, thereby preventing the ultrasonic generator 406 and the water guide member 407 from affecting the humidification efficiency of the first fan 401 and the water storage member 410.

[0036] Reference Figures 3 to 5 As shown, it can be understood that the refrigeration equipment of the second embodiment of the present invention can be specifically a refrigerator, a wine cabinet and other products. The refrigeration equipment includes a cabinet 101, a refrigeration component and a humidification component 100 of the first embodiment of the present invention. The cabinet 101 is provided with a storage room and an air supply duct 201 for conveying airflow to the storage room. The refrigeration component is used to provide a refrigeration environment for the storage room. The refrigeration component includes an evaporator 301 and a compressor, which is configured to generate a cooling airflow in a controlled manner and promote the cooling airflow to be sent to the storage room through the air supply duct 201. In other words, the refrigeration component is used to refrigerate the storage room. The humidification component 100 is arranged in the cabinet 101, configured to generate a high-humidity airflow in a controlled manner, and convey the high-humidity airflow to the air supply duct 201, so that the high-humidity airflow flows into the storage room with the cooling airflow. It can be understood that the moisture in the high-humidity airflow is large, which can increase the humidity in the storage room.

[0037] Reference Figure 4 and Figure 5 As shown, it can be understood that the air supply duct 201 includes a second air outlet 202 and a return air outlet 302 connected to the storage compartment, the second air outlet 202 is located at the top of the storage compartment, and the return air outlet 302 is located at the bottom of the storage compartment. The refrigeration device includes a second fan for promoting air circulation between the storage compartment and the air supply duct 201, and the first air outlet 104 is arranged at a position close to the return air outlet 302, that is, the first air outlet 104 is arranged on a side of the cabinet 101 close to the return air outlet 302, for example, the first air outlet 104 is located directly below the return air outlet 302, or the first air outlet 104 is located obliquely below the return air outlet 302. When the second fan and the humidification component 100 are both in working state, the high humidity airflow generated by the humidification component 100 is sent to the air supply duct 201 through the return air outlet 302, and enters the storage compartment through the second air outlet 202. After secondary acceleration by the second fan, the high-humidity airflow comes out from the second air outlet 202 and mixes more fully with the air in the storage room, thereby further improving the humidification efficiency.

[0038] For example, refer to Figure 3As shown, the cabinet 101 includes a shelf 103, and the humidifying assembly 100 is arranged on the shelf 103. The cabinet 101 is provided with an opening 102, and the opening 102 is connected to the storage room. The humidifying assembly 100 is located in the storage room, and the return air port 302 and the opening 102 are located on opposite sides of the storage room. The user takes and puts items from the opening 102, and the return air port 302 is far away from the user. The return air port 302 is located at the deepest part of the cabinet 101. That is, the return air port 302 and the humidifying assembly 100 are located on the same side of the storage room. In other words, the humidifying assembly 100 is located on the side of the shelf 103 close to the return air port 302. More specifically, the humidifying assembly 100 is located in the half area of ​​the shelf 103 close to the return air port 302, that is, the humidifying assembly 100 is located on the side of the midline of the shelf 103 close to the return air port 302.

[0039] It is understandable that the first fan 401 has a relatively small power and a relatively weak driving capability, and it is difficult to effectively deliver the high-humidity airflow generated by it to the upper area of ​​the storage compartment. The second fan is used to deliver cooling airflow to the storage compartment, and it has a relatively large power and a relatively strong driving capability. Therefore, the second fan can be cleverly used to deliver air to cause the high-humidity airflow generated by the humidification assembly 100 to flow at a high speed, thereby effectively delivering it to the entire space of the storage compartment.

[0040] It should be noted that when the humidifying component 100 is in working state, mainly in the stage of stopping cooling, even if the evaporator 301 is located in the air supply duct 201, the evaporator 301 is in a non-working state, and the second fan is kept turned on to accelerate the high-humidity air blown out by the humidifying component 100 and interact with the indoor air of the storage room, thereby reducing the probability of frost of the high-humidity airflow due to low temperature.

[0041] It is understandable that the refrigeration device further includes a first temperature sensor, a second temperature sensor, a humidity sensor and a controller, the first temperature sensor is used to detect the ambient temperature, the second temperature sensor is used to detect the temperature in the storage space, the humidity sensor is used to detect the humidity in the storage space, the controller is connected to the first temperature sensor, the second temperature sensor, the humidity sensor, the first fan 401 and the ultrasonic generator 406, and the controller is based on the signals transmitted by the first temperature sensor, the second temperature sensor and the humidity sensor. When the first temperature sensor detects that the ambient temperature is at a high temperature, and the temperature set by the refrigeration device is low temperature, the temperature in the storage space is detected to be lower than the set temperature, the set humidity is high humidity, and the humidity in the storage space is detected to be lower than the set humidity, the controller controls the first fan 401 and the ultrasonic generator 406 to turn on together. In other cases, when the humidity in the storage space is detected to be lower than the set humidity, the controller controls the first fan 401 to turn on and the ultrasonic generator 406 to turn off. When the humidity in the storage space is detected to be greater than or equal to the set humidity, the controller controls the first fan 401 and the ultrasonic generator 406 to turn off.

[0042] An embodiment of the present invention provides a control method for a refrigeration device, which is applied to a controller provided in the refrigeration device in the above embodiment, wherein the structure or component composition of the controller has been described in detail in the above embodiment and will not be repeated here. Figure 6 As shown, the control method of the embodiment of the present invention includes but is not limited to step S100, step S200, step S300, step S400, and step S500.

[0043] Step S100, obtaining the ambient temperature value Th, the temperature setting value Ts, the humidity setting value y, and the humidity measurement value x of the storage room.

[0044] In one embodiment, the temperature setting value Ts and the humidity setting value y are input by the user.

[0045] In another embodiment, the temperature setting value Ts and the humidity setting value y are called from a program stored in the refrigeration device.

[0046] In one embodiment, the ambient temperature value Th and the humidity measurement value x are detected by a humidity sensor.

[0047] Step S200: the humidity measurement value x is less than the humidity setting value y.

[0048] When the humidity measurement value x is less than the humidity setting value y, it indicates that the humidity in the storage room is low and does not meet the expected requirements. The humidification mode needs to be turned on to humidify the storage room to increase the humidity.

[0049] Step S300, determine whether the following conditions are met at the same time: the ambient temperature value Th is greater than the first preset value, the temperature setting value Ts is less than the second preset value, and the humidity setting value y is greater than the third preset value. If so, execute step S300; if not, execute step S400.

[0050] In one embodiment, the first preset value can be set to 30°C, the second preset value can be set to 8°C, and the third preset value can be set to 75%. When these three conditions are met at the same time, it means that the refrigeration equipment is in a high temperature environment and requires a low temperature and high humidity storage environment, and step S300 is executed to achieve efficient humidification. When one or more of the conditions are not met, step S400 is executed to adopt a general humidification solution to reduce the frequency of use of the ultrasonic oscillator and increase the service life.

[0051] In another embodiment, the first preset value can also be set to 28°C, 32°C, 35°C and other values, the second preset value can be set to 9°C, 6°C, 5°C and other values, and the third preset value can be set to 70%, 80%, 85% and other values.

[0052] Step S400, the refrigeration equipment operates in the first working mode: the first fan and the ultrasonic generator are controlled to turn on.

[0053] It is understandable that when the refrigeration equipment is set to low temperature and high humidity under high ambient temperature, turning on the first fan and the ultrasonic generator can superimpose the humidity increased by the two humidification methods, effectively improve the humidification efficiency, and meet the humidity requirements.

[0054] Step S500: the refrigeration device operates in the second working mode, the first fan is controlled to be turned on, and the ultrasonic generator is turned off.

[0055] It can be understood that when the refrigeration equipment is set to low temperature and high humidity in a non-high temperature environment, that is, the ambient temperature value Th is less than or equal to the first preset value, the temperature setting value Ts is less than the second preset value, and the humidity setting value y is greater than the third preset value, the high humidity air generated by turning on the first fan can meet the humidity requirements.

[0056] It can be understood that when the refrigeration equipment is set to non-low temperature and high humidity in a high temperature environment, that is, the ambient temperature value Th is greater than the first preset value, the temperature setting value Ts is greater than or equal to the second preset value, and the humidity setting value y is greater than the third preset value, the high humidity air generated by turning on the first fan can meet the humidity requirements.

[0057] It can be understood that when the refrigeration equipment is set to low temperature but not high humidity in a high temperature environment, that is, the ambient temperature value Th is greater than the first preset value, the temperature setting value Ts is less than the second preset value, and the humidity setting value y is less than or equal to the third preset value, the high humidity air generated by turning on the first fan can meet the humidity requirements.

[0058] Another embodiment of the present invention also provides a control method for a refrigeration device, such as Figure 7 As shown, Figure 7 yes Figure 6 FIG. 4 is a schematic diagram of an embodiment of a detailed process of step S400 in FIG. 4 , wherein step S400 includes but is not limited to step S410.

[0059] Step S410, controlling the second fan to turn on.

[0060] In this embodiment, when the refrigeration device enters the humidification mode, the second fan also enters the on state, and the second fan is used to supply air to cause the high-humidity airflow generated by the humidification component to enter the air supply duct from the return air port, thereby increasing the flow rate of the high-humidity airflow, thereby effectively delivering the high-humidity airflow to the entire space of the storage compartment, improving the humidification efficiency, and shortening the humidification time. By arranging the first air outlet of the humidification component adjacent to the return air port, after turning on the second fan and the humidification component, the high-humidity airflow enters the air supply duct through the return air port, and finally enters the storage compartment from the second air outlet. The second fan is used to deliver cooling airflow to the storage compartment, and has a large power and a strong driving ability. Therefore, the second fan can be cleverly used to participate in humidity control. The second fan supplies air to cause the high-humidity airflow generated by the humidification component to flow at a high speed, thereby reducing the humidity control cost and improving the humidification efficiency.

[0061] Another embodiment of the present invention also provides a control method for a refrigeration device, such as Figure 8 As shown, Figure 8 yes Figure 7 FIG. 4 is a schematic diagram of an embodiment of a detailed process of step S410 in FIG. 4 , wherein step S410 includes but is not limited to step S411.

[0062] Step S411, when the refrigeration component is in the on state, the speed of the second fan is Rn1.

[0063] Referring to Table 1, it can be understood that the speed of the second fan is divided into four gears: R1, R2, R3 and R4, and the speeds from R1 to R4 are arranged from small to large. The ambient temperature range is divided into eight ranges, and the ambient temperatures corresponding to ranges one to eight are increasing. It can be understood that when the refrigeration component is in the on state, it indicates that the storage room is in the refrigeration state. At this time, the speed Rn1 of the second fan is specifically R2 or R3. That is, the speed of the second fan is set to meet the refrigeration demand, and the temperature requirement is given priority when adjusting the humidity.

[0064] Table 1 Speed ​​control table of the second fan

[0065] Another embodiment of the present invention also provides a control method for a refrigeration device, such as Fig. 9 As shown, Fig. 9 yes Figure 7 FIG. 4 is a schematic diagram of an embodiment of a detailed process of step S410 in FIG. 4 , wherein step S410 includes but is not limited to step S412.

[0066] Step S412, when the refrigeration component is in the closed state, the rotation speed of the second fan is Rn2, wherein Rn2>Rn1.

[0067] It is understandable that when the refrigeration component is in the off state, indicating that the storage room is in a non-refrigeration state, the speed Rn2 of the second fan is set to R3 or R4, and Rn2>Rn1 is satisfied. That is, when Rn1 is set to R2, Rn2 is specifically R3 or R4; when Rn1 is set to R3, Rn2 is set to R4. In some embodiments, Rn2 is fixedly set to R4, that is, when the refrigeration component is in the off state, the speed of the second fan is increased to the maximum speed, which can make the humidity reach the set humidity as quickly as possible, with little impact on the temperature.

[0068] Another embodiment of the present invention also provides a control method for a refrigeration device, such as Fig.10 As shown, Fig.10 yes Figure 6 FIG. 5 is a schematic diagram of an embodiment of a detailed process of step S500 in FIG. 5 , wherein step S500 includes but is not limited to step S510.

[0069] Step S510, when x<ya, control the first fan and the second fan to turn on, wherein a is the first humidity compensation value.

[0070] It is understandable that when the set humidity is changed from a single point value y to a range value [ya,y], that is, when the humidity measurement value x falls within the range [ya,y], there is no need to turn on the humidification component and the second fan, which can avoid frequent startup of the second fan and the humidification component. The value of a can be a constant such as 8%, 5%, 3%. If the humidity setting value y is 60% and a is 5%, when the humidity measurement value x is 50%, the humidification component needs to be turned on to supplement the high-humidity airflow, and the refrigeration equipment enters the humidification mode; when the humidity measurement value x is 58%, the humidification component does not need to be turned on. However, this also has disadvantages, that is, when the refrigeration equipment enters the humidification mode, the detected humidity measurement value x is already much different from the humidity setting value y. If only the first fan is turned on, the humidification efficiency is slow and it takes a long time to reach the humidity setting value y. In this embodiment, when the refrigeration device enters the humidification mode, the second fan also enters the on state, and the second fan is used to supply air to cause the high-humidity airflow generated by the humidification component to enter the air supply duct from the return air port, thereby increasing the flow rate of the high-humidity airflow, thereby effectively delivering the high-humidity airflow to the entire space of the storage compartment, improving the humidification efficiency, and shortening the humidification time. By arranging the first air outlet of the humidification component adjacent to the return air port, after turning on the second fan and the first fan, the high-humidity airflow enters the air supply duct through the return air port, and finally enters the storage compartment from the second air outlet. The second fan is used to deliver cooling airflow to the storage compartment, and has a large power and a strong driving ability. Therefore, the second fan can be cleverly used to participate in humidity control. The second fan supplies air to cause the high-humidity airflow generated by the humidification component to flow at a high speed, thereby reducing the humidity control cost and improving the humidification efficiency.

[0071] The wind speed control logic of the second fan refers to step S411 and step S412.

[0072] Another embodiment of the present invention also provides a control method for a refrigeration device, such as Fig.11 As shown, Fig.11 yes Figure 6 FIG. 5 is a schematic diagram of an embodiment of a detailed process of step S500 in FIG. 5 , wherein step S500 includes but is not limited to step S520.

[0073] Step S520, when x>y+b, control the humidification component to be turned off, detect the temperature value Ti of the storage compartment and control the working state of the refrigeration component and the second fan according to the working state of the refrigeration component, wherein b is the second humidity compensation value, that is, the value of b is a constant, and the unit is humidity unit.

[0074] It is understandable that when the set humidity is changed from the single point value y to the range value [y,y+b], that is, when the humidity measurement value x falls within the range [y,y+b], the humidification component and the second fan do not need to be turned on, which can avoid frequent startup of the second fan and the humidification component. The value of b can be a constant such as 8%, 5%, 3%. If the humidity setting value y is 80% and a is 5%, when the humidity measurement value x is 88%, the humidification component needs to be turned off, and the refrigeration component and the second fan need to be turned on, and the refrigeration equipment enters the dehumidification mode; when the humidity measurement value x is 82%, the refrigeration component and the second fan do not need to be turned on. In the refrigeration mode, the air is cooled by the evaporator, so that the water vapor in the air condenses into water droplets, thereby achieving the dual effects of cooling and dehumidification. Specifically, when the refrigeration equipment is set to the refrigeration mode, the air in the storage room is sucked in and cooled by the evaporator. In this process, the water vapor in the air condenses due to the cold and is converted into liquid water, thereby achieving the dehumidification of the air in the storage room.

[0075] Another embodiment of the present invention also provides a control method for a refrigeration device, such as Fig.12 As shown, Fig.12 yes Fig.11 FIG. 5 is a schematic diagram of an embodiment of a detailed process of step S520 in FIG. 5 , wherein step S520 includes but is not limited to step S521.

[0076] Step S521, when the temperature value Ti of the storage compartment is less than or equal to the preset temperature value Ts, and the refrigeration component is in the on state, the refrigeration component and the second fan are controlled to be turned off.

[0077] It can be understood that when x>y+b, it indicates that the humidity measurement value x is greater than the required humidity setting value y, and dehumidification is normally required, and the refrigeration component is also in the on state, and dehumidification can be performed. However, the temperature sensor detects that the temperature value Ti of the storage room is less than or equal to the preset temperature value Ts, and starting the refrigeration component will cause the temperature of the storage room to continue to drop, affecting the temperature control. Therefore, the refrigeration component and the second fan are controlled to be turned off here. When there is a conflict between humidity control and temperature control, the temperature requirement is met first.

[0078] Another embodiment of the present invention also provides a control method for a refrigeration device, such as Fig.13 As shown, Fig.13 yes Fig.10 FIG. 5 is a schematic diagram of an embodiment of a detailed process of step S520 in FIG. 5 , wherein step S520 includes but is not limited to step S522.

[0079] Step S322, when the temperature value Ti of the storage compartment is greater than the preset temperature value Ts, and the refrigeration component is in the on state, the refrigeration component and the second fan remain in the on state.

[0080] It can be understood that when x>y+b, it indicates that the humidity measurement value x is greater than the required humidity setting value y. Normally, dehumidification is required, and the refrigeration component is also in the on state. The refrigeration component and the second fan continue to be in the on state, and the requirements of refrigeration and dehumidification are met at the same time. At this time, the speed of the second fan is controlled according to the temperature control logic when the storage room is in the refrigeration state.

[0081] Another embodiment of the present invention also provides a control method for a refrigeration device, such as Fig.14 As shown, Fig.14 yes Fig.11 FIG. 5 is a schematic diagram of an embodiment of a detailed process of step S520 in FIG. 5 , wherein step S520 includes but is not limited to step S523.

[0082] Step S323: When the temperature value Ti of the storage compartment is less than or equal to the preset temperature value Ts, and the refrigeration component is in the off state, the refrigeration component and the second fan are controlled to remain in the off state.

[0083] It can be understood that when x>y+b, it indicates that the humidity measurement value x is greater than the required humidity setting value y, and dehumidification is normally required. However, the temperature sensor detects that the temperature value Ti of the storage room is less than or equal to the preset temperature value Ts. Starting the refrigeration component will cause the temperature of the storage room to continue to drop, affecting the temperature control, and the refrigeration component is currently in the off state. Therefore, the refrigeration component and the second fan are controlled to remain in the off state. When there is a conflict between humidity control and temperature control, the temperature requirement is given priority.

[0084] Another embodiment of the present invention also provides a control method for a refrigeration device, such as Fig.15 As shown, Fig.15 yes Fig.11 FIG. 5 is a schematic diagram of an embodiment of a detailed process of step S520 in FIG. 5 , wherein step S520 includes but is not limited to step S524.

[0085] Step S524: when the temperature value Ti of the storage compartment is greater than the preset temperature value Ts, and the refrigeration component is in the off state, the refrigeration component and the second fan are controlled to be turned on.

[0086] It can be understood that when x>y+b, it indicates that the humidity measurement value x is greater than the required humidity setting value y. Normally, dehumidification is required, and the temperature value Ti of the storage room is detected to be greater than the preset temperature value Ts. Refrigeration is required to lower the temperature. The refrigeration component and the second fan are turned on to meet the requirements of refrigeration and dehumidification at the same time. At this time, the speed of the second fan is controlled according to the temperature control logic when the storage room is in the refrigeration state.

[0087] Another embodiment of the present invention also provides a control method for a refrigeration device, such as Fig.16 As shown, Fig.16 yes Figure 6 FIG. 5 is a schematic diagram of an embodiment of a detailed process of step S500 in FIG. 5 , wherein step S500 includes but is not limited to step S530.

[0088] Step S530: when ya≤x≤y+b, the humidification component is controlled to be turned off.

[0089] It is understandable that when the set humidity is changed from the single point value y to the range value [ya, y+b], that is, when the humidity measurement value x falls within the range [ya, y+b], the compressor and the second fan do not need to be turned on, which can avoid frequent starting of the compressor and the second fan. The value of a can be a constant such as 8%, 5%, 3%, and the value of b can be a constant such as 8%, 5%, 3%. If the humidity setting value y is 60%, a is 5%, and b is 5%, when the humidity measurement value x is 50%, the humidification component needs to be turned on to supplement the high humidity airflow, and the refrigeration equipment enters the humidification mode; when the humidity measurement value x is 58%, the humidification component does not need to be turned on; when the humidity measurement value x is 80%, the humidification component needs to be turned off, and it is determined whether to turn on the refrigeration component for dehumidification based on the detected temperature value. When ya≤x≤y+b, if the storage room is in the cooling state, the speed of the second fan is R2 or R3; if the storage room is in the non-cooling state, the speed of the second fan is R1 or R2. When the humidity is sufficient, the second fan is turned on to improve the uniformity of temperature and humidity in the refrigeration equipment. The wind is constantly rotating to ensure that the upper and lower parts of the storage room have uniform temperature and humidity.

[0090] Another embodiment of the present invention also provides a control method for a refrigeration device, such as Fig.17 As shown, Fig.17 This is a complete embodiment of a control method for a refrigeration device in which a single first fan performs humidification, which will be described below in conjunction with specific steps.

[0091] Get the humidity setting value y and the humidity measurement value x, judge the humidity, confirm the range of humidity, control the working mode of the refrigeration equipment, and then perform corresponding control. When x<y-5, it indicates that the humidity of the storage space is low, and the refrigeration equipment is controlled to be in humidification mode. When x>y+5, it indicates that the humidity of the storage space is high, and the refrigeration equipment is controlled to be in dehumidification mode. When y-5≤x≤y+5, it indicates that the humidity of the storage space meets the requirements and humidity control is not required. The following describes in detail the specific control process of each humidity range combined with the temperature conditions.

[0092] When x<y-5, it is determined whether the refrigeration equipment is in the refrigeration stage. If the refrigeration equipment is in the refrigeration stage, the speed of the second fan is the same as that of the fan with the same temperature control specification under the same conditions, that is, the opening and closing of the second fan, as well as the speed control are adjusted according to the needs of temperature control. You can refer to the speed control table of the storage room in the refrigeration state in Table 1, and turn on the first fan. If the refrigeration equipment is not in the refrigeration stage, the second fan runs at the speed of R4 gear, that is, the speed of the second fan is increased to the maximum speed, and the first fan is turned on until the humidity reaches the set humidity.

[0093] When x>y+5, it is determined whether the refrigeration equipment is in the refrigeration stage. If the refrigeration equipment is in the refrigeration stage, the speed of the second fan is the same as that of the fan with the same temperature control specification under the same conditions, that is, the opening and closing of the second fan, as well as the speed control are adjusted according to the needs of temperature control. You can refer to Table 1, the speed control table of the storage room in the refrigeration state, and turn on the humidification component. And it is determined in real time whether the temperature reaches the shutdown point, that is, whether the detected temperature value reaches the preset temperature value. If it reaches the shutdown point, the evaporator does not refrigerate, that is, the compressor is turned off, the second fan is not turned on, and the humidification component is not turned on. If the shutdown point is not reached, the evaporator continues to refrigerate, and the previous fan speed control strategy is continued. If the refrigeration equipment is not in the refrigeration stage, it is also necessary to determine whether the temperature reaches the shutdown point. If it does not reach the shutdown point, the evaporator starts to refrigerate, and the speed of the second fan is the same as that of the fan with the same temperature control specification under the same conditions. If it reaches the shutdown point, the evaporator does not refrigerate, that is, the compressor is turned off, the second fan is not turned on, and the humidification component is not turned on.

[0094] When y-5≤x≤y+5, the speed of the second fan is the same as that of the fan with temperature control specifications under the same conditions. You can refer to the speed control table in Table 1, where the storage room is in a non-refrigeration state (only executed when the humidity meets the requirements), and the humidification component is not turned on.

[0095] In the control strategies for the above three humidity ranges, it is finally necessary to read the new measurement value x in real time and then return to the step of judging the humidity.
