[0035] The optional embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] Example 1

[0037] In the preferred embodiment 1 of the present invention, a control method for a fresh-keeping compartment is provided, and the control method can be directly applied to a moisturizing compartment. A humidifier and a fan are arranged in the fresh-keeping compartment, and the humidifier can be an atomizer for uniform humidification. When there is condensation in the fresh-keeping compartment, there is moisture on the surface of the fresh-keeping items, and the fan is used to increase air convection, accelerate the evaporation of moisture on the surface of the food, and thus reduce the condensation on the surface of the food.

[0038] Specifically, Figure 1 An optional flow chart of the method is shown as follows: Figure 1 As shown, the method includes the following steps S102-S106:

[0039] S102: Obtain the current air humidity of the fresh-keeping room;

[0040] S104: Detecting the condensation area of ​​the fresh-keeping items in the fresh-keeping space;

[0041] S106: Control the humidification rate of the humidifier and the speed of the fan according to the current air humidity and condensation area to adjust the air humidity and control condensation.

[0042] In the above embodiment, a control scheme for a fresh-keeping room is provided, in which a humidifier and a fan are arranged for humidification and accelerating air flow. During the control process, the current air humidity of the fresh-keeping room and the condensation area of ​​the fresh-keeping items are obtained, and the humidification rate of the humidifier and the speed of the fan are controlled according to the current air humidity and the condensation area, so that the condensation is controlled while adjusting the air humidity, especially reducing the condensation during the humidification process, avoiding excessive condensation causing the fresh-keeping items to be soaked in water for a long time and causing decay and deterioration, thereby improving the fresh-keeping effect of the fresh-keeping room and the storage time of the fresh-keeping items.

[0043] In a preferred embodiment of the present invention, the humidification rate of the humidifier and the speed of the fan are controlled according to the current air humidity and the condensation area, including: determining the humidification rate of the humidifier according to the current air humidity; determining the speed of the fan according to the condensation area and adjusting the humidification rate. The humidification effect is mainly affected by the humidification rate of the humidifier. Therefore, in the humidity adjustment stage, the acceleration rate of the humidifier is first adjusted, such as the operating gear or operating power of the humidifier, so that the humidity is preliminarily adjusted. After adjusting the humidification rate of the humidifier, condensation control is performed. The condensation control is mainly adjusted by the speed of the fan, and the air flow is accelerated by the fan to reduce condensation. However, when there is more condensation, the fan reduces the condensation, the water evaporates, and the air humidity is further increased. Therefore, condensation control will also affect the air humidity. In the condensation control stage, it is also necessary to further adjust the humidification rate of the humidifier.

[0044] Specifically, the speed of the fan is determined according to the condensation area and the humidification rate is adjusted, including: when the condensation area is less than the first preset area, the larger the condensation area, the higher the speed of the fan, and the humidification rate remains unchanged; when the condensation area is greater than or equal to the first preset area, the speed of the fan is no longer increased and the humidification rate of the humidifier is reduced; or, the area ratio of the condensation area to the total area of ​​the fresh-keeping items is calculated, when the area ratio is less than the first preset ratio, the larger the area ratio, the higher the speed of the fan; when the area ratio is greater than or equal to the first preset ratio, the speed of the fan is no longer increased and the humidification rate of the humidifier is reduced. The amount of condensation can be characterized by the condensation area or the condensation area ratio. When the condensation is less, that is, the condensation area or the condensation area ratio is small, the condensation control has little effect on the humidity, so the humidity is not adjusted during the condensation control stage. When there is a lot of condensation, that is, when the condensation area or the condensation area ratio is large, the condensation control has a greater impact on the humidity. Therefore, the humidification rate of the humidifier is further adjusted in the condensation control stage. The main method is that the fan speed is no longer increased and the humidification rate of the humidifier is reduced. In this way, reducing the operating power of the humidifier and combining with a higher fan speed can accelerate the evaporation of water on the surface of the food, thereby reducing condensation. The reduced humidification rate of the humidifier is compensated by the water evaporated by condensation, that is, the air humidity is maintained. In addition, the fan speed is no longer increased and the humidification rate of the humidifier also achieves the effect of reducing power consumption, making the whole machine more energy-efficient.

[0045] Optionally, the humidification rate of the humidifier is determined according to the current air humidity, including: judging whether the current air humidity has reached the preset humidity; when the current air humidity has not reached the preset humidity, calculating the difference between the preset humidity and the current air humidity; determining the humidification rate of the humidifier according to the difference between the preset humidity and the current air humidity; wherein, the greater the difference between the preset humidity and the current air humidity, the faster the humidification rate of the humidifier. Since increasing the air humidity during the humidification process will increase condensation, and reducing the air humidity during the dehumidification process will inhibit condensation, the humidity adjustment stage of the present invention is mainly a humidification stage, and condensation is inhibited while humidifying. In the humidification stage, the humidification rate of the humidifier can be determined by the difference between the preset humidity and the current air humidity, that is, the larger the difference, the lower the indoor humidity, and the humidification rate of the humidifier needs to be increased to adjust the humidity as soon as possible so that the humidity meets the demand.

[0046] In order to achieve further energy saving and avoid unnecessary energy waste, after determining the speed of the fan according to the condensation area and adjusting the humidification rate, it also includes: when the condensation area is less than the first preset area, detecting whether the current air humidity reaches the preset humidity; when the current air humidity reaches the preset humidity, controlling the humidifier and the fan to stop running; when the current air humidity does not reach the preset humidity, maintaining the current running state of the humidifier and the fan. Control the humidifier and the fan to humidify the room while controlling the condensation, so that the humidifier and the fan are stopped when the humidity in the room reaches the preset humidity and the condensation is less, so that after humidification and reducing the condensation on the surface of the food, energy waste is further avoided and energy efficiency is improved.

[0047] Optionally, after the user puts the food in, the humidity H in the chamber is detected, and the humidity difference ΔH with the preset humidity H0 is calculated. If the humidity difference ΔH≤H1, the ratio S of the moisture area on the surface of the food to the surface area of ​​the food is identified. If S≤S2, the atomizer runs at power W1 for time t2 and the fan speed V1 for time t3; otherwise, the atomizer stops running, maintains the fan speed V1 for time t1 and then stops, and continues to humidify the chamber by evaporating the moisture on the surface of the food, t3=t1+t2.

[0048] If the humidity difference H1≤ΔH≤H2, then identify the ratio S of the moisture area on the surface of the food to the surface area of ​​the food. If S≤S1, the atomizer runs at power W2 and the fan speed V1; if S1≤S≤S2, the atomizer runs at power W2 and the fan speed V2; if S>S2, the atomizer runs at W1 and the fan speed V2.

[0049] If the humidity difference ΔH>H2, the ratio S of the moisture area on the surface of the food to the surface area of ​​the food is identified. If S≤S1, the atomizer runs at power W3 and the fan speed V1; if S1≤S≤S2, the atomizer runs at power W3 and the fan speed V2; if S>S2, the atomizer runs at W2 and the fan speed V2. Among them, 5%≤H1≤10%, 30%≤H2≤50%, 0<S1≤25%, 50%≤S2≤75%, 0<W1<W2<W3, 0<V1<V2. In this way, the condensation on the surface of the food can be controlled while humidifying.

[0050] In a preferred embodiment of the present invention, an ion generator is also provided in the fresh-keeping room, and the ion generator and the fan are turned on and off at the same time. The ion generator can generate negative ions with a sterilizing function, and the atomizer can atomize water and discharge it through the atomizing water outlet. Then, under the action of the fan, the negative ions generated by the ion generator are combined with the atomized water to sterilize the atomized water. At the same time, the atomized water carries the negative ions into the fresh-keeping room to sterilize the fresh-keeping room.

[0051] Preferably, an image recognition device is also provided in the fresh-keeping room, which is used to collect images of fresh-keeping items in the fresh-keeping room; detect the condensation area of ​​the fresh-keeping items in the fresh-keeping space, including: obtaining images of the fresh-keeping items in the fresh-keeping room; and identifying the moisture area on the fresh-keeping items according to the images of the fresh-keeping items as the condensation area. The image recognition device can collect images of food in the fresh-keeping room, and calculate the moisture area and surface area of ​​the food through the image and data processing system. The operation of the atomizer and the fan is controlled according to the ratio of the moisture area on the surface of the food to the surface area of ​​the food, that is, the ratio of the condensation area.

[0052] Another method for controlling a fresh-keeping compartment is provided in a preferred embodiment 1 of the present invention. Specifically, Figure 2 An optional flow chart of the method is shown as follows: Figure 2 As shown, the method includes the following steps S201-S222:

[0053] S201: Start;

[0054] S202: Detect the humidity H in the room, calculate and preset the humidity H 0 Humidity difference ΔH=H 0 -H;

[0055] S203: Is ΔH≤H1 true? If so, proceed to step S204; otherwise proceed to step S210; calculate the humidity difference ΔH between the indoor humidity H and the preset humidity H0. If the humidity difference ΔH≤H 1 , it means that the humidity in the room is slightly different from the preset humidity. At this time, the ratio S of the surface moisture of the food to the surface area of ​​the food is identified;

[0056] S204: Identify the ratio S of the moisture area on the surface of the food to the surface area of ​​the food;

[0057] S205: Is S≤S1 true? If so, proceed to step S207; otherwise, proceed to step S206;

[0058] S206: the atomizer stops running and the fan runs at a speed of V1; if S>S1, the atomizer is controlled to stop running and the fan runs at a speed of V1. At this time, the fan blows air into the room to increase air convection, accelerate the evaporation of water on the surface of the food, and thus reduce condensation on the surface of the food;

[0059] S207: Is H≥H0 established? If yes, proceed to step S209; otherwise, proceed to step S208;

[0060] S208: The atomizer is operated at power W1 and fan speed V1; when S≤S1, it is determined whether the humidity H in the room reaches the preset humidity H0. If H<H0, the atomizer is controlled to operate at power W1 and fan speed V1 to humidify the room. When the humidity in the room reaches the preset humidity, the atomizer stops operating, so that condensation on the surface of the food can be reduced while humidifying.

[0061] S209: The atomizer stops running, and the fan stops running;

[0062] S210: Is ΔH≤H2 established? If yes, proceed to step S211; otherwise, proceed to step S217;

[0063] S211: Identify the ratio S of the moisture area on the surface of the food to the surface area of ​​the food; if the humidity H1<ΔH≤H2, it means that the humidity in the room is at a medium state, and then identify the ratio S of the moisture area on the surface of the food to the surface area of ​​the food;

[0064] S212: Is S≤S1 true? If so, proceed to step S206; otherwise, proceed to step S213;

[0065] S213: Is S≤S2 established? If yes, proceed to step S215; otherwise, proceed to step S214;

[0066] S214: The atomizer runs at power W1 and fan speed V2; if S>S2, the atomizer runs at W1 and fan speed V2. The fan runs at a higher speed to accelerate the evaporation of moisture on the surface of the food. The evaporated moisture further increases the humidity in the room, and the low-power atomizer is used to achieve a humidification effect in the room;

[0067] S215: The atomizer runs at power W2 and the fan speed V2; if S1<S≤S2, the atomizer runs at W2 and the fan speed V2. The higher fan speed increases the air convection in the room, which can accelerate the evaporation of moisture on the surface of the food, thereby reducing condensation while quickly humidifying;

[0068] S216: The atomizer runs at power W2 and fan speed V1; if S≤S1, the atomizer is controlled to run at W2 and fan speed V1. The atomizer humidifies at a higher power, which can achieve rapid humidification in the room. Since the condensation area is small, a lower fan speed can be used to avoid energy waste;

[0069] S217: Identify the ratio S of the moisture area on the surface of the food to the surface area of ​​the food; if the humidity ΔH>H2, it means that the humidity in the room is low, and then identify the ratio S of the moisture area on the surface of the food to the surface area of ​​the food;

[0070] S218: Is S≤S1 established? If yes, proceed to step S219; otherwise, proceed to step S220;

[0071] S219: The atomizer runs at power W3 and fan speed V1, and then returns to S202; if S≤S1, the atomizer is controlled to run at W3 and fan speed V1. The atomizer humidifies quickly with higher power and lower fan speed, and with the higher humidity difference in the room, it can reduce condensation on the food while humidifying;

[0072] S220: Is S≤S2 established? If yes, proceed to step S221; otherwise, proceed to step S222;

[0073] S221: The atomizer runs at power W3 and fan speed V2, then returns to S202; S1<S≤S2, then the atomizer runs at W3 and fan speed V2. Increasing the fan speed can accelerate the evaporation of condensed water on the surface of the food, thereby reducing condensation on the surface of the food;

[0074] S222: The atomizer runs at power W2 and fan speed V2, then returns to S202; S>S2, the atomizer runs at W2 and fan speed V2. Reducing the operating power of the atomizer and combining it with a higher fan speed can accelerate the evaporation of water on the surface of the food, thereby reducing condensation.

[0075] In the above embodiment, the power and speed of the humidification device are controlled by linking the humidity of the compartment with the condensation area on the surface of the food, so as to finally control the condensation on the surface of the food while humidifying, and prevent the food from being soaked in water for a long time and causing it to rot and deteriorate. At the same time, the humidified water is sterilized, and the sterilizing substance can enter the compartment with the water to sterilize the compartment environment and the surface of the food, so as to avoid cross contamination of the food.

[0093] Figure 6 An optional structural schematic diagram of a humidifying device is shown, such as Figure 6 As shown, the humidifying device 1 is composed of a fan 2, an ion generator 3, and an atomizer 4 (humidifier). The ion generator can generate negative ions with a sterilizing function, and the atomizer 4 can atomize water and discharge it through the atomizing water outlet 5. Then, under the action of the fan 2, the negative ions generated by the ion generator combine with the atomized water to sterilize the atomized water. At the same time, the atomized water carries the negative ions into the fresh-keeping room to sterilize the fresh-keeping room. In the humidifying device, the fan and the ion generator are started and stopped at the same time, that is, when the fan is started, the ion generator is also started, and when the fan stops running, the ion generator also stops running. The atomizer can be controlled to start and stop separately.

[0094] The image recognition device 6 can collect images of food in the fresh-keeping room, and calculate the surface moisture area and surface area of ​​the food through the image and data processing system. According to the ratio of the surface moisture area of ​​the food to the surface area of ​​the food, the operation of the atomizer and fan of the humidification device is controlled. The humidity sensor 7 can detect the humidity in the fresh-keeping room, and according to the change of humidity, the operation of the humidification device is controlled by the controller.

[0095] In the above embodiment, a control scheme for a fresh-keeping room is provided, in which a humidifier and a fan are arranged for humidification and accelerating air flow. During the control process, the current air humidity of the fresh-keeping room and the condensation area of ​​the fresh-keeping items are obtained, and the humidification rate of the humidifier and the speed of the fan are controlled according to the current air humidity and the condensation area, so that the condensation is controlled while adjusting the air humidity, especially reducing the condensation during the humidification process, avoiding excessive condensation causing the fresh-keeping items to be soaked in water for a long time and causing decay and deterioration, thereby improving the fresh-keeping effect of the fresh-keeping room and the storage time of the fresh-keeping items.
