[0002] The refrigeration chamber and / or freezing chamber in a refrigeration device (such as a refrigerator) often rely on the opening and closing of a damper in the refrigeration device to control the refrigeration demand of the refrigeration device.

[0072] Embodiments of the present application are described in detail below with reference to the accompanying drawings, in which the same or similar notations used throughout the drawings and the specific description below mean the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0073] The refrigeration equipment and the control method and device thereof in the embodiments of the present application are described below with reference to the accompanying drawings.

[0074] It should be noted that the refrigeration equipment in the embodiments can be but not limited to a refrigerator, a freezer, etc.

[0075] Figure 1 is a flowchart of a control method of a refrigeration equipment in one embodiment disclosed by the present application. As shown in the figure, the control method of the refrigeration equipment in the embodiments includes the following steps: Figure 1

[0076] S101, obtaining a chamber humidity of a target chamber in the refrigeration equipment.

[0077] Specifically, a humidity sensor is arranged in the target chamber in the refrigeration equipment, and the humidity sensor can be used to detect the humidity in the target chamber, so as to obtain the chamber humidity of the target chamber. The target chamber can be but not limited to a refrigerating chamber, a freezing chamber, etc.

[0078] S102, identifying that the chamber humidity is greater than a first humidity threshold value, controlling a damper to open to a preset angle, and controlling a fan in the refrigeration equipment to open, wherein the preset angle is less than a maximum opening angle of the damper.

[0079] ​Specifically, the obtained chamber humidity is compared with the first humidity threshold, that is, the size relationship between the chamber humidity and the first humidity threshold can be identified. Wherein, when it is identified that the chamber humidity is greater than the first humidity threshold, it indicates that the current humidity in the target chamber is large; since the temperature near the damper in the refrigeration equipment is low, at this time, the condensate water is easy to be generated on the damper and / or near the damper area, and when the condensate water freezes, it will cause the damper switch to be abnormal, thereby affecting the refrigeration effect of the refrigeration equipment. Therefore, in the embodiment, when the chamber humidity is greater than the first humidity threshold, the damper is controlled to be opened to a preset angle, and the fan in the refrigeration equipment is controlled to be opened, so that the airflow generated by the fan can immediately remove the condensate water on the damper and / or near the damper area, thereby preventing the problem of freezing of the condensate water and causing the damper switch to be abnormal.

[0080] It should be noted that the preset angle in the embodiment is less than the maximum opening angle of the damper, for example, when the maximum opening angle is 90°, the preset angle can be 30°. Wherein, the contact area between the airflow and the damper can be increased through the preset angle, so that the airflow can blow away the condensate water on the damper, and then be guided to the platform at the bottom of the damper; at the same time, an inclined angle can be formed between the damper and the platform at the bottom of the damper, so that the airflow can directly blow or obliquely blow the area near the damper, thereby facilitating the airflow to guide the condensate water in the area near the damper to the platform at the bottom of the damper.

[0081] It should be understood that since when the damper is opened, it often means that the target chamber needs to be refrigerated, at this time, the fan needs to be opened; and when the damper is closed, it often means that the target chamber does not need to be refrigerated, at this time, the fan needs to be closed to save energy. Therefore, in the embodiment, the damper and the fan work synchronously, that is, when the damper is opened, the fan is opened, and when the damper is closed, the fan is closed. That is to say, in the embodiment, when it is identified that the damper is in the opened state, the fan is controlled to be opened; when it is identified that the fan is in the closed state, the fan is controlled to be closed.

[0082] In summary, the control method of the refrigeration equipment provided in the embodiment, when it is identified that the chamber humidity is greater than the first humidity threshold, the damper is controlled to be opened to a preset angle, and the fan in the refrigeration equipment is controlled to be opened, so that the airflow generated by the fan can immediately remove the condensate water on the damper and near the damper area, thereby avoiding the problem of freezing of the condensate water on the damper and / or near the damper area and causing the damper switch to be abnormal.

[0083] In some embodiments, in the refrigeration equipment, whether the chamber temperature is high or low is a criterion for whether the chamber sends a refrigeration request. Among them, when the chamber temperature is low, if the damper is in the open state, the temperature in the chamber will continue to decrease, which cannot meet the user's demand, so the chamber does not need to send a refrigeration request, and the refrigeration equipment controls the damper to be closed to avoid the temperature in the chamber continuing to decrease; when the chamber temperature is high, if the damper is in the closed state, the temperature in the chamber will continue to increase, which cannot meet the user's demand, so the chamber needs to send a refrigeration request, and the refrigeration equipment controls the damper to be opened to avoid the temperature in the chamber continuing to increase. It can be seen that the chamber temperature has a great influence on the state of the damper, and the state of the damper affects the use effect of the refrigeration equipment. Therefore, in order to ensure the stable operation of the refrigeration equipment to meet the user's demand and improve the user's satisfaction, after the damper is controlled to be opened to the preset angle, the damper can be controlled according to the chamber temperature of the target chamber.

[0084] As a possible implementation manner, as shown in Figure 2 After the damper is controlled to be opened to the preset angle, the damper is controlled according to the chamber temperature of the target chamber, including the following steps:

[0085] S201, obtaining the chamber temperature of the target chamber.

[0086] Specifically, a temperature sensor is arranged in the target chamber of the refrigeration equipment, and the temperature sensor can be used to detect the temperature in the target chamber, so as to obtain the chamber temperature of the target chamber.

[0087] S202, identifying that the chamber temperature is less than a first preset temperature, and controlling the damper to be periodically opened and closed.

[0088] Specifically, the obtained chamber temperature is compared with the first preset temperature, that is, the size between the chamber temperature and the first preset temperature is identified. When the chamber temperature is less than the first preset temperature, it indicates that the temperature in the target chamber at this time has reached the expected temperature of the user, that is, the target chamber no longer needs to send a refrigeration request, so the refrigeration equipment needs to close the damper. But when the damper is in the closed state and the chamber humidity in the target chamber is less than the first humidity threshold, condensate water is easy to be generated on the damper and / or in the area near the damper, so at this time the damper can be controlled to be periodically opened and closed, so that the condensate water on the damper and / or in the area near the damper can be immediately removed, thereby avoiding the problem that the condensate water freezes when the temperature in the target chamber is low, causing abnormal opening and closing of the damper.

[0089] Further, after identifying that the intermediate chamber temperature is less than the first preset temperature, if it is identified that the intermediate chamber humidity is less than or equal to the first humidity threshold, it indicates that it is difficult to generate condensate water on and / or near the damper at this time, and at this time, the damper can be controlled to be closed, i.e., the damper is no longer controlled to be periodically opened and closed.

[0090] Further, in order to ensure that the damper can be stably opened and closed to ensure stable operation of the refrigeration equipment, before controlling the damper to be periodically opened and closed, the opening and closing period and / or the opening duration of the damper can also be determined. For example, as shown in Figure 3 the following steps can be included:

[0091] S301, obtaining a target humidity interval to which the intermediate chamber humidity belongs.

[0092] Generally, by comparing the obtained intermediate chamber humidity with the pre-set humidity interval, the target humidity interval to which the intermediate chamber temperature belongs can be obtained. For example, the pre-set humidity interval includes (20, 25) and (26, 30); if the intermediate chamber humidity is 27, the target humidity interval to which the intermediate chamber humidity belongs is (26, 30).

[0093] S302, determining the opening and closing period and / or the opening duration of the damper according to the target humidity interval.

[0094] Generally, after the target humidity interval is determined, by querying the pre-set mapping relationship between the humidity interval and the opening and closing period and / or the opening duration of the damper, the corresponding opening and closing period and / or the opening duration can be determined. For example, the pre-set mapping relationship between the humidity interval and the opening and closing period and / or the opening duration of the damper includes: when the humidity interval is (20, 25), the opening and closing period is 8s and the opening duration is 3s; when the humidity interval is (26, 30), the opening and closing period is 6s and the opening duration is 4s; therefore, when the target humidity interval is (26, 30), the corresponding opening and closing period is 6s and the opening duration is 4s.

[0095] Optionally, as shown in Figure 4 the following steps can be included in determining the opening and closing period and / or the opening duration of the damper according to the target humidity interval:

[0096] S401, identifying that the upper endpoint of the target humidity interval is less than or equal to a second humidity threshold, and determining that the opening and closing period is a first opening and closing period and / or the opening duration is a first duration, wherein the first humidity threshold is less than the second humidity threshold.

[0097] S402, identifying that the lower endpoint of the target humidity interval is greater than the second humidity threshold, and determining that the opening and closing period is a second opening and closing period and / or the opening duration is a second duration, wherein the first opening and closing period is greater than the second opening and closing period.

[0098] That is, in this embodiment, as the chamber humidity gradually increases and the target humidity interval to which it belongs changes, the opening and closing period of the damper is controlled to be shortened to ensure that the condensate water on and / or near the damper is immediately eliminated. In addition, the opening duration of the damper can be controlled to remain unchanged, or the opening duration of the damper can be controlled to be extended, which can be determined according to actual conditions and is not limited here.

[0099] As another possible implementation, as shown in Figure 5 After the damper is controlled to open to the preset angle, the damper is controlled according to the chamber temperature of the target chamber, including the following steps:

[0100] S501, obtaining the chamber temperature of the target chamber.

[0101] Specifically, a temperature sensor is arranged in the target chamber of the refrigeration device, and the temperature sensor can be used to detect the temperature in the target chamber, so as to obtain the chamber temperature of the target chamber.

[0102] S502, identifying that the chamber temperature is greater than or equal to a first preset temperature, and obtaining the duration for maintaining the opening angle of the damper at a preset angle.

[0103] S503, identifying that the duration reaches a preset duration, and controlling the damper to open to a maximum opening angle.

[0104] Specifically, after obtaining the chamber temperature, the chamber temperature is compared with the first preset temperature, that is, the size between the chamber temperature and the first preset temperature is identified. When the chamber temperature is greater than or equal to the first preset temperature, it indicates that the temperature in the target chamber does not reach the expected temperature of the user at this time, that is, the target chamber needs to send a refrigeration request at this time, and therefore the damper needs to be opened by the refrigeration device. However, when the chamber humidity in the target chamber is less than the first humidity threshold, condensate water is easily generated on and / or near the damper. At this time, when the damper is directly opened to the maximum opening angle from the closed state, the contact area between the airflow generated by the fan and the damper is small, and the angle between the flow direction of the airflow and the area near the damper is approximately a straight angle, which makes it difficult for the condensate water generated on and / or near the damper to be blown away by the airflow. Therefore, in this embodiment, when the target chamber requests refrigeration, the damper also needs to be controlled to open to a preset angle.

[0105] In addition, after identifying that the chamber temperature is greater than or equal to the first preset temperature, if it is identified that the chamber humidity is less than or equal to the first humidity threshold, it indicates that it is difficult to generate condensate water on and / or near the damper at this time, and at this time the damper can be controlled to continuously open to the maximum opening angle at a preset speed, that is, the damper does not need to be opened to the preset angle again, but is directly opened to the maximum opening angle.

[0106] Further, after the damper is opened for a certain time, the condensate water on and / or near the damper has been drained to the platform at the bottom of the damper, at which time the damper can be controlled to open to the maximum opening angle. That is, when it is identified that the chamber temperature is greater than or equal to the first preset temperature, the opening angle of the damper can be recorded by using a timer or other timing device for a predetermined duration, and when it is identified that the duration reaches the predetermined duration, the damper is controlled to open to the maximum opening angle.

[0107] Further, because the amount of condensate water generated on and / or near the damper is different under different chamber humidities, the time required for airflow to blow away the condensate water of different amounts is different. Therefore, in order to ensure that the condensate water on and / or near the damper can be completely eliminated under different chamber humidities, the predetermined duration can also be determined according to the chamber humidity. As shown in Figure 6 The control method comprises the following steps:

[0108] S601, determining a third duration required for the damper to open according to a target humidity interval to which the chamber humidity belongs.

[0109] Specifically, according to the target humidity interval to which the chamber humidity belongs, the mapping relationship between the humidity interval and the third duration is queried, and the third duration required for the damper to open can be determined.

[0110] S602, taking the third duration as the predetermined duration.

[0111] Specifically, after obtaining the third duration required for the damper to open, the third duration can be taken as the predetermined duration.

[0112] For ease of understanding, the control method of the refrigeration equipment provided in the embodiment is explained and described below. As shown in Figure 7 The control steps of the control method of the refrigeration equipment comprise:

[0113] S701, obtaining the chamber humidity of the target chamber.
