Description

TECHNICAL FIELD

[0002] The refrigeration chamber of a refrigeration device such as a refrigerator or a freezer often lacks fresh air circulation, and gas exchange can only be performed when the door is opened. If the door is opened less frequently, the gas in the box cannot be replaced for a long time, which can easily breed bacteria and affect the preservation effect of food in the refrigeration chamber. In related technologies, a refrigeration device is provided with a fresh air structure that communicates the inside and outside of the refrigeration device and can be controlled to open to introduce fresh air from the outside of the refrigeration device to the inside to achieve gas exchange. However, in the case of introducing fresh air, the air humidity in the refrigeration chamber depends on the humidity of the introduced fresh air, and accurate control of the air humidity in the refrigeration chamber cannot be achieved.

DETAILED DESCRIPTION

[0038] The exemplary embodiments will be described in detail herein with reference to the accompanying drawings.

[0039] In conjunction Figures 1 to 5 As shown, the present application provides a refrigeration equipment 10, which comprises a refrigeration chamber 100, and the refrigeration equipment 10 is operated to realize temperature regulation in the refrigeration chamber 100. In conjunction Figure 1 As shown, the refrigeration equipment 10 further comprises a controller 20, and a first fresh air system 30, a second fresh air system 40 and a humidity monitoring device 50 electrically connected with the controller 20. The first fresh air system 30 is configured to humidify fresh air to be introduced into the refrigeration chamber 100 in a starting state, and input the humidified fresh air into the refrigeration chamber 100. The second fresh air system 40 is configured to dehumidify fresh air to be introduced into the refrigeration chamber 100 in a starting state, and input the dehumidified fresh air into the refrigeration chamber 100. The humidity monitoring device 50 is configured to monitor air humidity in the refrigeration chamber 100. The controller 20 is configured to control the first fresh air system 30 and the second fresh air system 40 to start or stop operation according to the air humidity monitored by the humidity monitoring device 50.

[0040] By using the refrigeration equipment 10 provided by the present application, the first fresh air system 30 configured to humidify fresh air to be introduced into the refrigeration chamber 100, and the second fresh air system 40 configured to dehumidify fresh air to be introduced into the refrigeration chamber 100, the controller 20 controls the first fresh air system 30 and the second fresh air system 40 according to the air humidity in the refrigeration chamber 100, so as to control the humidity of fresh air to be introduced into the refrigeration chamber 100 according to the current air humidity, and the humidity in the refrigeration chamber 100 can be controlled while the fresh air in the refrigeration chamber 100 is replaced.

[0041] Here, the controller 20 controlling the first fresh air system 30 and the second fresh air system 40 to start or stop operation includes: the controller 20 controlling the first fresh air system 30 to start operation alone, the controller 20 controlling the second fresh air system 40 to start operation alone, and the controller 20 controlling the first fresh air system 30 and the second fresh air system 40 to stop operation.

[0042] In conjunction Figure 2 In some embodiments, the refrigeration equipment 10 further comprises a bacterial density monitoring device 60 electrically connected with the controller 20. The bacterial density monitoring device 60 is arranged in the refrigeration chamber 100, and is configured to monitor the bacterial density in the refrigeration chamber 100. Exemplarily, the bacterial density monitoring device 60 is a biological sensing counting device. In some embodiments, the controller 20 is configured to control the first fresh air system 30 or the second fresh air system 40 to start according to the bacterial density monitoring device 60.

[0043] Specifically, in some embodiments, the controller 20 is configured to control the first fresh air system 30 or the second fresh air system 40 to start up in the case that the bacterial density in the refrigeration compartment 100 is greater than a first density threshold.

[0044] In some embodiments, the controller 20 is configured to control the first fresh air system 30 or the second fresh air system 40 to stop running according to the bacterial density monitoring device 60. Specifically, in some embodiments, the controller 20 is configured to control the first fresh air system 30 or the second system currently in the starting state to stop running in the case that the bacterial density in the refrigeration compartment 100 is less than a second density threshold. In this way, the need for fresh air replacement can be realized by bacterial density monitoring, so as to automatically perform fresh air replacement when the bacterial density is large and the bacterial density needs to be reduced by fresh air replacement, and to automatically end the fresh air replacement process when the bacterial density is reduced to the extent that fresh air replacement is no longer needed to continue reducing the bacterial density.

[0045] In some embodiments, the first density threshold is greater than the second density threshold. In the implementation process, the first density threshold and the second density threshold can be set according to actual needs, and are not specifically limited. Exemplarily, the first density threshold can be 3000 CFU / m 3 , and the second density threshold can be 1000 CFU / m 3 .

[0046] In some embodiments, the controller 20 is configured to control the first fresh air system 30 to start up in the case that the air humidity in the refrigeration compartment 100 is less than a first humidity threshold, and to control the second fresh air system 40 to start up in the case that the air humidity in the refrigeration compartment 100 is greater than a second humidity threshold. The first humidity threshold is less than or equal to the second humidity threshold. In this way, the humidity can be automatically increased in the case of low humidity, and the humidity can be automatically reduced in the case of high humidity, so as to realize automatic adjustment of the humidity in the refrigeration compartment 100.

[0047] In some embodiments, the refrigeration device 10 further comprises a third fresh air system for blowing fresh air into the refrigeration compartment 100 in the starting state, where the fresh air is not humidified nor dehumidified. The controller 20 is configured to control the third fresh air system to start up in the case that the air humidity in the refrigeration compartment 100 is greater than or equal to the first humidity and less than or equal to the second humidity.

[0048] In some embodiments, it can be determined whether the fresh air function needs to be started, i.e., the first fresh air system 30 or the second fresh air system 40, according to the bacterial density obtained by the bacterial density monitoring device 60. Then, it can be determined that the fresh air system to be started is the first fresh air system 30 or the second fresh air system 40 according to the air humidity in the refrigeration compartment 100.

[0049] In combination Figure 2 And Figure 3 The structure of the refrigeration device 10 is specifically described as shown in the figure. The first fresh air system 30 described above includes a first fresh air pipe 31, a first fan 32 and a humidifying device 33. Among them, the first fresh air pipe 31 is connected between the external environment and the refrigeration room 100. The first fan 32 is used to suck fresh air in the external environment into the first fresh air pipe 31 in the starting state. The humidifying device 33 is used to increase the humidity of the fresh air blown from the first fresh air pipe 31 to the refrigeration room 100.

[0050] The second fresh air system 40 described above includes a second fresh air pipe 41, a second fan 42 and a dehumidifying device 43. Among them, the second fresh air pipe 41 is connected between the external environment and the refrigeration room 100. The second fan 42 is used to suck fresh air in the external environment into the second fresh air pipe 41 in the starting state. The dehumidifying device 43 is used to reduce the humidity of the fresh air blown from the second fresh air pipe 41 to the refrigeration room.

[0051] It should be noted that the humidifying device 33 and the dehumidifying device 43 can be a normally open device that cannot be controlled to close, or a controllable device that can be controlled to close or open. Corresponding to different device settings, the connection mode of the controller 20 with the first fresh air system 30 and the second fresh air system 40 is different, and the control range of the controller 20 is also different, which is described here:

[0052] In some embodiments, the humidifying device 33 and the dehumidifying device 43 are in a normally open state, and the controller 20 is electrically connected with the first fan 32 and the second fan 42. At this time, controlling the first fresh air system 30 to open is to control the first fan 32 to open, and controlling the second fresh air system 40 to open is to control the second fan 42 to open. In the case that the first fan 32 is opened, the humidified fresh air enters the refrigeration room 100; in the case that the second fan 42 is opened, the dehumidified fresh air enters the refrigeration room 100. The controller 20 is configured to control the first fan 32 and the second fan 42 to open or close according to the air humidity monitored by the humidity monitoring device 50. Specifically, the controller 20 is configured to control the first fan 32 to open when the air humidity in the refrigeration room 100 is less than the first humidity threshold, and to control the second fan 42 to open when the air humidity in the refrigeration room 100 is greater than the second humidity threshold.

[0053] In some embodiments, the humidifying device 33 is in an open state, and the dehumidifying device 43 is controllable to open or close. The controller 20 is electrically connected with the first fan 32, the second fan 42 and the dehumidifying device 43. At this time, controlling the first fresh air system 30 to open means controlling the first fan 32 to open, and controlling the second fresh air system 40 to open means controlling the second fan 42 and the dehumidifying device 43 to open. Specifically, in the case that the first fan 32 is opened, the humidified fresh air enters the refrigeration compartment 100; in the case that the second fan 42 and the dehumidifying device 43 are opened, the dehumidified fresh air enters the refrigeration compartment 100. The controller 20 is configured to control the first fan 32, the second fan 42 and the dehumidifying device 43 to open or close. Specifically, the controller 20 is configured to control the first fan 32 to start in the case that the air humidity in the refrigeration compartment 100 is less than the first humidity threshold, and control the second fan 42 and the dehumidifying device 43 to open in the case that the air humidity in the refrigeration compartment 100 is greater than the second humidity threshold.

[0054] In some embodiments, the humidifying device 33 is controllable to open or close, and the dehumidifying device 43 is in an open state. The controller 20 is electrically connected with the first fan 32, the second fan 42 and the humidifying device 33. At this time, controlling the first fresh air system 30 to open means controlling the first fan 32 and the humidifying device 33 to open, and controlling the second fresh air system 40 to open means controlling the second fan 42 to open. In the case that the first fan 32 and the humidifying device 33 are opened, the humidified fresh air enters the refrigeration compartment 100; in the case that the second fan 42 is opened, the dehumidified fresh air enters the refrigeration compartment 100. The controller 20 is configured to control the first fan 32, the second fan 42 and the humidifying device 33 to open or close according to the air humidity monitored by the humidity monitoring device 50. Specifically, the controller 20 is configured to control the first fan 32 and the humidifying device 33 to open in the case that the air humidity in the refrigeration compartment 100 is less than the first humidity threshold, and control the second fan 42 to open in the case that the air humidity in the refrigeration compartment 100 is greater than the second humidity threshold.

[0055] In some embodiments, the humidifying device 33 and the dehumidifying device 43 can be controlled to be opened or closed, and the controller 20 is electrically connected with the first fan 32, the second fan 42, the humidifying device 33 and the dehumidifying device 43. At this time, the first fresh air system 30 is controlled to be turned on, i.e. the first fan 32 and the humidifying device 33 are controlled to be turned on, and the second fresh air system 40 is controlled to be turned on, i.e. the second fan 42 and the dehumidifying device 43 are controlled to be turned on. In the case that the first fan 32 and the humidifying device 33 are turned on, the humidified fresh air enters the refrigeration compartment 100, and in the case that the second fan 42 and the dehumidifying device 43 are turned on, the dehumidified fresh air enters the refrigeration compartment 100. The controller 20 is configured to control the first fan 32, the second fan 42, the humidifying device 33 and the dehumidifying device 43 to be opened or closed according to the air humidity monitored by the humidity monitoring device 50. Specifically, the controller 20 is configured to control the first fan 32 and the humidifying device 33 to be turned on in the case that the air humidity in the refrigeration compartment 100 is less than the first humidity threshold, and to control the second fan 42 and the dehumidifying device 43 to be turned on in the case that the air humidity in the refrigeration compartment 100 is greater than the second humidity threshold. In this way, since the humidifying device 33 and the dehumidifying device 43 can be independently controlled to be turned on or off, the first fresh air system 30 and the second fresh air system 40 both have two modes of adjusting humidity and sending fresh air and sending fresh air alone, and can be controlled according to actual humidity adjustment requirements, which is beneficial to improving the accuracy of the fresh air control process.

[0056] In combination Figure 4 As shown in FIG. 8, in some embodiments, the refrigeration equipment 10 further comprises a water storage device 70 and an air vent pipe 80, the humidifying device 33 comprises a heating device 331, and the dehumidifying device 43 comprises a refrigeration device 431. Specifically, the water storage device 70 has a water storage cavity 700 with an upper opening. The air vent pipe 80 comprises a collection port 801 connected to the refrigeration compartment 100 and a water outlet 802 connected to the water storage cavity 700. In some embodiments, the water storage device 70 is a water receiving box, and the air vent pipe 80 is a drain pipe. The condensed water in the refrigeration compartment 100 enters the drain pipe through the collection port 801 and enters the water storage cavity 700 of the water receiving box through the drain pipe. In this way, the structure is improved on the basis of the original water receiving box and drain pipe of the refrigeration equipment 10 for processing condensed water, which is beneficial to saving the cost of modification. In other embodiments, the water storage device 70 and the air vent pipe 80 are not the aforementioned water receiving box and drain pipe, but are separately added devices. In this way, the water storage device 70 and the air vent pipe 80 can be set according to actual humidity adjustment requirements and fresh air adjustment requirements, which is beneficial to further meeting the humidity adjustment and fresh air supply requirements.

[0057] The first fresh air duct 31 includes a first air inlet 311 and a first air outlet 312, and the second fresh air duct 41 includes a second air inlet 411 and a second air outlet 412. The first air inlet 311 and the second air inlet 411 are connected to the external environment, and the first air outlet 312 and the second air outlet 412 extend into the ventilation pipe 80, so that the first fresh air duct 31 and the second fresh air duct 41 are in communication with the inner cavity of the ventilation pipe 80. The humidifying device 33 includes a heating device 331 for heating the water in the water storage cavity 700 in the starting state. The dehumidifying device 43 includes a refrigeration device 431 for cooling the water in the water storage cavity 700 in the starting state. The water storage cavity 700 stores water, which can evaporate to a certain extent at any temperature, and the evaporation degree is related to the temperature. When the heating device 331 is running, it has a warming effect on the water in the water storage cavity 700, promoting the evaporation of the water in the water storage cavity 700, so that the humidity of the fresh air entering the refrigeration compartment 100 through the first fresh air duct 31 increases. When the refrigeration device 431 is running, it has a cooling effect, so that the humidity of the fresh air entering the refrigeration compartment 100 through the second fresh air duct 41 decreases. In this way, the humidity of the fresh air can be adjusted.

[0058] Here, the specific implementation of the first air inlet 311 and the second air outlet 412 extending into the ventilation pipe 80 is described: in some embodiments, the first air outlet 312 and the second air outlet 412 extend into the ventilation pipe 80 through the water outlet 802. In some embodiments, the sidewall of the ventilation pipe 80 is provided with a connecting port, one of the first air outlet 312 and the second air outlet 412 extends into the ventilation pipe 80 through the water outlet 802, and the other of the first air outlet 312 and the second air outlet 412 extends into the ventilation pipe 80 through the connecting port. In some embodiments, the sidewall of the ventilation pipe 80 is provided with a first connecting port and a second connecting port, the first air outlet 312 extends into the ventilation pipe 80 through the first connecting port, and the second air outlet 412 extends into the ventilation pipe 80 through the second connecting port.

[0059] In some embodiments, the refrigeration device 10 further comprises a partition device 90. One end of the partition device 90 extends into the air duct 80 and abuts against the inner wall of the air duct 80, and the other end abuts against the bottom wall of the water storage device 70. The height of the partition device 90 arranged in the air duct 80 is greater than the height of the first air outlet 312 and the second air outlet 412. In this way, the first fresh air duct 31 and the second fresh air duct 41 can be partially separated to avoid interference between them. For example, when the second fan 42 starts to operate, the time interval between the operation of the second fan 42 and the stop of the first fan 32 can be short. The air duct 80 near the second fresh air duct 41 and the second air outlet 412 can still contain humid air or even water on the inner wall. After the partition device 90 is arranged, the air path of the second fan 42 will not pass through the second fresh air duct 41 and the air duct 80 near the second air outlet 412 when the second fan 42 is running, thereby avoiding the introduction of air with too high humidity into the refrigeration compartment 100. In addition, the air can be directly blown out from the fresh air duct on the other side when the fan on one side is running.

[0060] For the foregoing heating device 331, in combination Figure 5 As shown in FIG. 13, in some embodiments, the heating device 331 comprises an exhaust pipe 3311 of the compressor. Specifically, the first fresh air duct 31 is closer to the exhaust pipe 3311 of the compressor than the second fresh air duct 41. In this way, the heat generated by the operation of the compressor itself can be used to achieve the heating function, without the need to add a separate heating device 331, which is beneficial to save costs. In some embodiments, the heating device 331 is a heating wire, a heating sheet or other heating element with independent heating function. In this way, the heating function can be controlled to start and stop, which can ensure the real-time and accuracy of the start and stop control. Further, in some embodiments, the heating device 331 comprises a plurality of heating sheets.

[0061] In some embodiments, when the heating device 331 comprises the exhaust pipe 3311 of the compressor, the controller 20 is further configured to adjust the rotation speed of the compressor according to the air humidity in the refrigeration compartment 100. In this way, the temperature of the exhaust pipe 3311 of the compressor can be controlled by controlling the rotation speed of the compressor, thereby changing the amount of water evaporated by heat, and further controlling the humidity of the fresh air entering the refrigeration compartment 100.

[0062] Specifically, in some embodiments, the smaller the air humidity in the refrigeration compartment 100, the greater the compressor rotation speed. The smaller the air humidity in the refrigeration compartment 100, the greater the humidification demand. Increasing the compressor rotation speed is conducive to increasing the temperature of the compressor exhaust pipe 3311, thereby increasing the humidification efficiency of the fresh air and making the air humidity in the refrigeration compartment 100 increase faster. In some embodiments, the controller 20 is configured to adjust the compressor rotation speed according to the air humidity in the refrigeration compartment 100 when the first fan 32 runs for a first set time length. Specifically, when the first fan 32 runs for the first set time length, if the air humidity in the refrigeration compartment 100 is less than a third humidity threshold, the compressor rotation speed is increased. If the first fan 32 has run for the first set time length and the air humidity in the refrigeration compartment 100 is less than the third humidity threshold, it indicates that the current humidification efficiency is low and cannot meet the humidity adjustment demand in the refrigeration compartment 100. Therefore, the temperature of the compressor exhaust pipe 3311 is increased by increasing the compressor rotation speed, thereby increasing the humidification efficiency. It can be understood that, on the contrary, if the air humidity in the refrigeration compartment 100 is greater than a set humidity threshold when the first fan 32 runs for the first set time length, the compressor rotation speed is decreased, thereby meeting the humidity adjustment demand while reducing energy consumption. The set humidity threshold is greater than the third humidity threshold described above.

[0063] In some embodiments, when the heating device 331 includes a plurality of heating pieces, the controller 20 is further configured to adjust the number of heating pieces in the starting state according to the air humidity in the refrigeration compartment 100. Specifically, the plurality of heating pieces are connected in parallel with the power supply and are provided with switches to control the on-off of the power supply and each heating piece. By controlling each switch, the number of heating pieces in the starting state can be adjusted. In this way, by adjusting the number of heating pieces in the starting state, the control of the heating temperature can be realized, thereby changing the amount of water evaporated by heating, and further realizing the control of the humidity of the fresh air entering the refrigeration compartment 100.

[0064] Specifically, in some embodiments, the smaller the air humidity in the refrigeration compartment 100, the more the number of heating elements in the starting state. The smaller the air humidity in the refrigeration compartment 100, the greater the humidification demand. Increasing the number of heating elements in the starting state helps to improve the humidification efficiency of the fresh air, so that the air humidity in the refrigeration compartment 100 is increased faster. In some embodiments, the controller 20 is configured to adjust the number of heating elements in the starting state according to the air humidity in the refrigeration compartment 100 when the first fan 32 runs for a first set time length. Specifically, when the first fan 32 runs for the first set time length, if the air humidity in the refrigeration compartment 100 is less than a third humidity threshold, the number of heating elements in the starting state is increased. If the first fan 32 has run for the first set time length, and the air humidity in the refrigeration compartment 100 is less than the third humidity threshold, it means that the current humidification efficiency is low and cannot meet the humidity adjustment demand in the refrigeration compartment 100. Therefore, by increasing the number of heating elements in the starting state, the temperature of the compressor exhaust pipe 3311 is increased, thereby improving the humidification efficiency. It can be understood that, on the contrary, if the air humidity in the refrigeration compartment 100 is greater than a set humidity threshold when the first fan 32 runs for the first set time length, the number of heating elements in the starting state is reduced, so as to meet the humidity adjustment demand while reducing energy consumption. Here, the set humidity threshold is greater than the third humidity threshold mentioned above.

[0065] For the foregoing refrigeration device 431, in some embodiments, the refrigeration device 431 includes a plurality of refrigeration elements 4311. The controller 20 is further configured to adjust the number of refrigeration elements 4311 in the starting state according to the air humidity in the refrigeration compartment 100. As shown, the plurality of refrigeration elements 4311 are connected in parallel and connected to the power supply, and are provided with switches to realize on-off control between the power supply and each refrigeration element 4311, and the number of refrigeration elements 4311 in the starting state can be adjusted by controlling each switch. In this way, by adjusting the number of refrigeration elements 4311 in the starting state, the control of the heating temperature can be realized, so as to change the amount of water evaporated by heating, and then realize the control of the humidity of the fresh air entering the refrigeration compartment 100. The refrigeration element 4311 can be a semiconductor refrigeration sheet. Figure 5

[0066] ​Specifically, in some embodiments, the greater the air humidity in the refrigeration compartment 100, the greater the number of refrigeration pieces 4311 in the starting state. The greater the air humidity in the refrigeration compartment 100, the greater the dehumidification demand. Increasing the number of refrigeration pieces 4311 in the starting state is conducive to reducing the amount of water evaporated by heat, thereby improving the dehumidification efficiency of the fresh air, and further reducing the air humidity in the refrigeration compartment 100. In some embodiments, the controller 20 is configured to adjust the number of refrigeration pieces 4311 in the starting state according to the air humidity in the refrigeration compartment 100 when the time length of the second fan 42 in the open state reaches the first set time length. Specifically, when the time length of the second fan 42 in the open state reaches the first set time length, if the air humidity in the refrigeration compartment 100 is greater than the fourth humidity threshold, the number of refrigeration pieces 4311 in the starting state is increased. If the time length of the second fan 42 in the open state has reached the first set time length, and the air humidity in the refrigeration compartment 100 is greater than the fourth humidity threshold, it indicates that the current dehumidification efficiency is low and cannot meet the humidity adjustment demand in the refrigeration compartment 100. Therefore, the dehumidification efficiency is improved by increasing the number of refrigeration pieces 4311 in the starting state. It can be understood that, on the contrary, if the air humidity in the refrigeration compartment 100 is lower than the set humidity threshold when the time length of the second fan 42 reaches the first set time length, the number of refrigeration pieces 4311 in the starting state is reduced, thereby meeting the humidity adjustment demand while reducing energy consumption. Here, the set humidity threshold is less than the fourth humidity threshold described above.

[0067] In combination Figure 6 As shown in the drawings, the embodiments of the present application provide a control method of a refrigeration device, the refrigeration device comprising a refrigeration compartment, the control method comprising steps S101 and S103.

[0068] Step S101, in response to a fresh air starting instruction, obtaining the air humidity in the refrigeration compartment.

[0069] Step S102, determining the humidity adjustment demand in the refrigeration compartment according to the air humidity.

[0070] Step S103, adjusting the humidity of the fresh air to be entered into the refrigeration compartment according to the humidity adjustment demand.

[0071] The control method of the refrigeration device provided by the embodiments of the present application can determine the humidity adjustment demand according to the current air humidity in the refrigeration compartment when the fresh air needs to be started, and further adjust the humidity of the fresh air to be entered into the refrigeration compartment according to the current humidity adjustment demand, thereby realizing the consideration of the humidity control in the refrigeration compartment while the fresh air in the refrigeration compartment is replaced.

[0072] In some embodiments, the refrigeration device herein is the refrigeration device in any of the preceding embodiments, and the control method of the refrigeration device is applied to a controller of the refrigeration device.

[0073] The air humidity in the refrigeration compartment is obtained, i.e., the controller obtains the air humidity monitored by the humidity monitoring device arranged in the refrigeration compartment. The humidity of the fresh air to be introduced into the refrigeration compartment is adjusted according to the humidity adjustment requirement, i.e., the first fresh air system and the second fresh air system are started or stopped.

[0074] In combination with Figure 7 It is shown that the present application provides another control method of a refrigeration device, including steps S201 to S207.

[0075] Step S201, in response to a fresh air starting instruction, obtaining the air humidity in the refrigeration compartment.

[0076] Step S202, determining whether the air humidity is less than a first humidity threshold.

[0077] If yes, steps S203 and S204 are executed; if no, step S205 is executed.

[0078] Step S203, determining that the humidity adjustment requirement is to increase humidity.

[0079] Step S204, performing a humidification operation on the fresh air to be introduced into the refrigeration compartment.

[0080] That is, starting the first fresh air system. Specifically, the operation of starting the first fresh air system is related to the specific structure of the first fresh air system. The specific operation can be determined by referring to the related description of the structure of the refrigeration device in the preceding embodiments, which will not be described here.

[0081] Step S205, determining whether the air humidity is greater than a second humidity threshold.

[0082] The first humidity threshold is less than or equal to the second humidity threshold.

[0083] If yes, step S206 is executed.

[0084] Step S206, determining that the humidity adjustment requirement is to reduce humidity.

[0085] Step S207, performing a dehumidification operation on the fresh air to be introduced into the refrigeration compartment.

[0086] That is, starting the second fresh air system. Specifically, the operation of starting the second fresh air system is related to the specific structure of the second fresh air system. The specific operation can be determined by referring to the related description of the structure of the refrigeration device in the preceding embodiments, which will not be described here.

[0087] It is to be noted that Figure 7The judgment process in the illustrated embodiment is only an example, and in actual implementation, a judgment mode capable of screening out both cases of air humidity less than the first humidity threshold value and air humidity greater than the second humidity threshold value can be implemented.

[0088] In some embodiments, the control method further includes: adjusting a running power of the humidifying operation and / or the dehumidifying operation according to the air humidity in the refrigeration compartment. In this way, the humidity of the fresh air entering the refrigeration compartment can be adjusted according to the air humidity in the refrigeration compartment, which is conducive to improving the accuracy of air humidity control in the refrigeration compartment.

[0089] Specifically, in some embodiments, adjusting the running power of the humidifying operation and / or the dehumidifying operation according to the air humidity in the refrigeration compartment includes: if the current humidity adjustment requirement is to increase humidity, the smaller the air humidity in the refrigeration compartment, the greater the running power of the humidifying operation. In this way, better humidification effect can be achieved, and the air humidity in the refrigeration compartment can be increased faster. In some embodiments, adjusting the running power of the humidifying operation and / or the dehumidifying operation according to the air humidity in the refrigeration compartment includes: if the current humidity adjustment requirement is to decrease humidity, the greater the air humidity in the refrigeration compartment, the greater the running power of the dehumidifying operation. In this way, better dehumidification effect can be achieved, and the air humidity in the refrigeration compartment can be decreased faster.

[0090] Specifically, in some embodiments, adjusting the running power of the humidifying operation and / or the dehumidifying operation according to the air humidity in the refrigeration compartment includes: in the case where the duration of the fresh air entering the refrigeration compartment reaches the first set duration, if the air humidity in the refrigeration compartment is less than a third humidity threshold value, increasing the running power of the humidifying operation. In this case, the efficiency of the running humidifying operation is low, and cannot meet the current humidification requirement, so the running power of the humidifying operation is increased to increase the air humidity in the refrigeration compartment faster. In some embodiments, adjusting the running power of the humidifying operation and / or the dehumidifying operation according to the air humidity in the refrigeration compartment includes: in the case where the duration of the fresh air entering the refrigeration compartment reaches the first set duration, if the air humidity in the refrigeration compartment is greater than a fourth humidity threshold value, increasing the running power of the dehumidifying operation. In this case, the efficiency of the running dehumidifying operation is low, and cannot meet the current dehumidification requirement, so the running power of the dehumidifying operation is increased to decrease the air humidity in the refrigeration compartment faster.

[0091] In some embodiments, the control method further includes: obtaining a bacteria density in the refrigeration compartment, and adjusting an air intake rate of the fresh air entering the refrigeration compartment according to the bacteria density. Here, the controller obtains the bacteria density in the refrigeration compartment through a bacteria density monitoring device. The bacteria density in the refrigeration compartment can reflect the actual requirement of the fresh air replacement, and thus adjusting the air intake rate of the fresh air according to the bacteria density is conducive to improving the accuracy of the fresh air replacement process and ensuring the fresh air replacement effect.

[0092] Specifically, in some embodiments, the adjusting the fresh air intake rate into the refrigeration compartment according to the bacteria density comprises: in a case where the duration of the fresh air intake into the refrigeration compartment reaches a second set duration, and the bacteria density in the refrigeration compartment is greater than a third density threshold, increasing the fresh air intake rate into the refrigeration compartment. In a case where the duration of the fresh air intake into the refrigeration compartment has reached the second set duration, and the bacteria density is still greater than the third density threshold, it indicates that the current fresh air operation may not meet the requirement of reducing the bacteria density by replacing fresh air at this time, and therefore the fresh air intake rate is increased to improve the efficiency of replacing fresh air. In a case where the second density threshold is used as a boundary condition for controlling the fresh air function to be closed, the third density threshold is set to be greater than the second density threshold.

[0093] The adjustment of the fresh air intake rate is achieved by controlling the rotation speed of the fan, i.e., the first fan or the second fan mentioned above. Increasing the fresh air intake rate means increasing the rotation speed of the fan. If the fan currently running is the first fan, the rotation speed of the first fan is adjusted; if the fan currently running is the second fan, the rotation speed of the second fan is adjusted.

[0094] In some embodiments, the control method further comprises: adjusting the fresh air intake rate into the refrigeration compartment according to the air humidity in the refrigeration compartment. The air humidity in the refrigeration compartment can reflect the humidity adjustment requirement, and the control of the fresh air intake rate according to the air humidity is conducive to improving the accuracy of the humidity adjustment process.

[0095] Specifically, in some embodiments, the adjusting the fresh air intake rate into the refrigeration compartment according to the air humidity in the refrigeration compartment comprises: in a case where the duration of the fresh air intake into the refrigeration compartment reaches a third set duration, and the humidity adjustment requirement is to increase the humidity, if the air humidity in the refrigeration compartment is less than a fifth humidity threshold, increasing the fresh air intake rate into the refrigeration compartment. This case indicates that the current humidification process cannot meet the requirement of increasing the humidity, and therefore the fresh air intake rate into the refrigeration compartment is increased, which improves the rate of the fresh air with high humidity into the refrigeration compartment, thereby increasing the air humidity in the refrigeration compartment more quickly.

[0096] In some embodiments, the adjusting the air intake rate of the fresh air into the refrigeration compartment according to the air humidity in the refrigeration compartment comprises: in a case that the duration of the fresh air into the refrigeration compartment reaches the third set duration and the humidity adjustment requirement is to reduce the humidity, if the air humidity in the refrigeration compartment is greater than the sixth humidity threshold, increasing the air intake rate of the fresh air into the refrigeration compartment. This case means that the current operation condition cannot meet the humidity reduction requirement, so the air intake rate of the fresh air into the refrigeration compartment is increased, the rate of the fresh air with lower humidity into the refrigeration compartment is increased, and the air humidity in the refrigeration compartment is reduced faster.

[0097] For the first set duration, the second set duration and the third set duration described above, in the implementation process, they can be set according to actual requirements and the actual operation capacity of the fresh air function, and are not limited to specific values. For example, in some embodiments, the first set duration, the second set duration and the third set duration can be set to 2 hours. That is, the fresh air function is judged and adjusted every 2 hours.

[0098] In some embodiments, the control method further comprises obtaining the bacterial density in the refrigeration compartment and issuing a fresh air start instruction according to the bacterial density. Specifically, issuing the fresh air start instruction according to the bacterial density comprises: issuing the fresh air start instruction in a case that the bacterial density is greater than the first density threshold. Because the bacteria in the refrigeration compartment breed and gradually accumulate due to a long time without fresh air, the bacterial density in the refrigeration compartment can reflect the fresh air replacement requirement. In the use process of the refrigeration device, the bacterial density in the refrigeration compartment is monitored to reflect the fresh air replacement requirement, so that the fresh air function is automatically started in time to replace the fresh air. In some embodiments, the fresh air start instruction can also be input by the user through the input device. In this way, the user experience can be optimized in response to the current actual requirement of the user.

[0099] In some embodiments, the control method further comprises obtaining the bacterial density in the refrigeration compartment and issuing a fresh air stop instruction according to the bacterial density. Specifically, issuing the fresh air stop instruction according to the bacterial density comprises: issuing the fresh air stop instruction in a case that the bacterial density is less than the second density threshold. After the fresh air function is started, the bacterial density is continuously monitored so that the fresh air function is automatically stopped when the bacterial density decreases to the second density threshold, thereby avoiding unnecessary operation of the fresh air function and wasting energy. The second density threshold is less than the first density threshold. The fresh air stop instruction controls the fresh air function to stop, and the specific control component is determined according to the current operation condition. For example, the first fan and the heating device are in the open state, and the controller controls the first fan and the heating device to stop running in response to the fresh air stop instruction. Other cases operate in a similar manner, which will not be listed one by one here.

[0100] Herein Figure 8 The control method of the refrigeration equipment includes steps S301 to S308.

[0101] In step S301, the bacterial density in the refrigeration chamber is obtained.

[0102] In step S302, it is determined whether the bacterial density is greater than a first density threshold.

[0103] If yes, step S303 is executed. If no, step S301 can be continuously executed to continuously monitor the bacterial density in the refrigeration chamber.

[0104] In step S303, a fresh air starting instruction is issued.

[0105] In step S304, the air humidity in the refrigeration chamber is obtained in response to the fresh air starting instruction.

[0106] In step S305, the humidity adjustment requirement in the refrigeration chamber is determined according to the air humidity.

[0107] In step S306, the humidity of the fresh air to be introduced into the refrigeration chamber is adjusted according to the humidity adjustment requirement.

[0108] In step S307, it is determined whether the bacterial density is less than a second density threshold.

[0109] If yes, step S308 is executed.

[0110] In step S308, a fresh air stopping instruction is issued.

[0111] That is, whether the fresh air function needs to be started or stopped is determined according to the bacterial density in the refrigeration chamber, and during the operation of the fresh air function, the fresh air with different humidity is controlled to enter the refrigeration chamber according to the air humidity in the refrigeration chamber, so that the fresh air and humidity control are considered.
