Detailed implementation manners

[0018] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Components of the embodiments of the present application usually described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application to be protected, but merely represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the scope of protection of the present application.

[0020] It should be noted that like reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0021] In the description of the present application, it should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", etc. is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this application is usually placed during use. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present application. In addition, terms such as "first", "second", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.

[0022] It should be noted that, without conflict, different features in the embodiments of the present application can be combined with each other.

[0023] The inventor found through research that during the production and assembly of the door body of a refrigeration device (such as a push-pull refrigerator), due to the gravity of the door body itself, it may tilt downward after assembly, resulting in a smaller gap between the bottom of the door body and the bottom of the cabinet, while the gap between the upper part of the door body and the cabinet is normal or larger. At this time, a gap difference is formed between the upper and bottom parts of the door body and the cabinet. On the one hand, since the gap between the upper part of the door body and the cabinet is relatively large, it may lead to loose connection between the door body and the cabinet, and then cause the cold air in the refrigeration device to flow out, increasing the energy consumption of the refrigeration device and easily causing condensation or frosting. On the other hand, due to the gap difference formed between the upper and bottom parts of the door body and the cabinet, the different surfaces and unequal heights of the door body affect the aesthetics of the refrigeration device, thereby reducing the overall quality of the refrigeration device.

[0024] To solve the above-mentioned technical problems, the inventor has innovatively designed the following technical solutions. The specific implementation solutions of this application will be described in detail below with reference to the accompanying drawings.

[0025] Please refer to Figure 1 , Figure 1 which is a schematic flow chart of the steps of the method for adjusting the door body gap of the refrigeration device provided in this embodiment. This method is applied to the control unit in the refrigeration device. The refrigeration device further includes a cabinet, a door body fixedly connected to the cabinet, and a gap adjustment device provided on one side of the cabinet close to the door body. In this embodiment, the refrigeration device can be a refrigerator, such as a push-pull refrigerator, or a freezer, or other devices for refrigeration. The specific type of the refrigeration device is not specifically limited here.

[0026] The cabinet includes a cabinet bottom. The refrigeration device further includes a first sensor and a second sensor. The first sensor is provided inside the cabinet and is used to detect the opening and closing state of the door body. The first sensor can be provided on the side wall of the cabinet or on the bottom of the cabinet. The specific installation position of the first sensor is not specifically limited here. It can be installed close to the door body. The second sensor is provided on one side of the cabinet bottom close to the door body and is used to detect the gap between the cabinet bottom and the door body bottom. For a push-pull door body, due to the gravity of the door body itself, it may tilt downward after assembly, resulting in a smaller gap between the cabinet bottom and the door body bottom. Therefore, in this embodiment, the second sensor can be used to detect the gap value between the cabinet bottom and the door body bottom, and determine whether there is a deviation based on the gap value.

[0027] In addition, in this embodiment, the number of the second sensors can also be two. One is provided on the cabinet at the bottom of the door body, and the other is provided on the cabinet at the upper part of the door body. Whether there is a deviation is determined by detecting the gap values of the two. And if a gap difference is detected, after gap adjustment by the gap adjustment device, the two second sensors can be used to detect whether the gaps between the upper and bottom parts of the door body and the cabinet are uniform.

[0028] Among them, the first sensor and the second sensor are electrically connected to the control unit. In this embodiment, the control unit can be electrically connected to the first sensor and the second sensor through wireless communication means (such as Bluetooth, WiFi, etc.). Exemplarily, the control unit can obtain switch state parameters and the clearance value between the bottom of the box body and the bottom of the door body, etc. from the first sensor and the second sensor. The control unit can generate a control instruction according to the collected parameters, and control operations such as the closing and starting of the second sensor and the clearance adjustment of the clearance adjustment device based on the control instruction.

[0029] It should be noted that the specific number of the first sensor and the second sensor is not specifically limited here and can be selected according to the actual situation.

[0030] Next, the Figure 1 shown process will be elaborated in detail. The method for adjusting the door clearance of the refrigeration equipment can specifically include the following steps.

[0031] Step S11, obtain the switch state parameter of the door detected by the first sensor at a preset time interval.

[0032] In this step, the switch state parameter may include parameters such as the opening and closing angle of the door and the switch speed.

[0033] In this embodiment, the first sensor can be a door switch sensor.

[0034] It should be noted that the preset time interval is not specifically limited here and can be set according to the actual situation. The specific type of the first sensor is not specifically limited here and can be selected according to the actual situation.

[0035] Step S12, determine the switch state of the door based on the switch state parameter.

[0036] In this step, the control unit of the refrigeration equipment analyzes and processes the switch state parameter to judge the switch state of the door. Among them, the switch state includes the closed state and the open state. For example, when the first sensor detects that the opening and closing angle of the door is close to 0 degrees and the switch speed is 0, the control unit determines that the door of the refrigeration equipment is in the closed state at this time. When the first sensor detects that both the opening and closing angle of the door and the switch speed are within the preset opening and closing angle range and the preset switch speed range, it is determined that the door of the refrigeration equipment is in the open state at this time.

[0037] Step S13, control the working state of the second sensor according to the switch state of the door, where the initial working state of the second sensor is the closed state.

[0038] In this embodiment, when the door body is in the open state, there is no need to adjust the gap between the door body and the box body. Therefore, only when it is detected that the door body is in the closed state, the control unit generates a first control instruction and sends the first control instruction to the second sensor to activate the second sensor.

[0039] Step S14, when the operating state of the second sensor is the activated state, obtain the gap value between the bottom of the box body and the bottom of the door body detected by the second sensor.

[0040] In this embodiment, the second sensor can be a radar sensor, which uses the reflection principle of electromagnetic waves to accurately measure the distance (i.e., the gap value) between the bottom of the box body and the bottom of the door body.

[0041] It should be noted that the specific type of the second sensor is not specifically limited here and can be selected according to the actual situation. For example, the second sensor can also be a laser distance sensor or an ultrasonic sensor, etc.

[0042] Step S15, control the gap adjustment device to adjust the gap according to the gap value.

[0043] In this embodiment, when it is determined based on the gap value that there is a gap deviation, the control unit generates a second control instruction and sends the second control instruction to the gap adjustment device to achieve gap adjustment.

[0044] Furthermore, step S13 can be implemented in the following manner.

[0045] First, if the door body is in the open state, maintain the operating state of the second sensor as the closed state.

[0046] Next, if the door body is in the closed state, adjust the operating state of the second sensor to the activated state.

[0047] In this embodiment, if the door body is in the open state, it is in a non-sealed contact state with the box body, and at this time, it is meaningless to measure the gap between the bottom of the box body and the bottom of the door body. Therefore, only when the door body is in the closed state, the second sensor is activated, which avoids additional sensor activation and data collection operations, thereby saving energy, reducing the energy consumption of the refrigeration equipment, and at the same time extending the service life of the second sensor.

[0048] Furthermore, step S15 can be implemented in the following manner.

[0049] Step S150, control the gap adjustment device to adjust the gap according to the gap value and the preset gap value.

[0050] Furthermore, please refer to Figure 2 , Figure 2It is a schematic diagram of the sub-step process of step S150. Step S150 can also be implemented in the following manner.

[0051] Sub-step S151: Compare the clearance value with a preset clearance value.

[0052] Sub-step S152: Control the clearance adjustment device to adjust the clearance according to the comparison result between the clearance value and the preset clearance value.

[0053] In this embodiment, it is possible to determine whether the clearance deviation between the door body and the cabinet body is normal by comparing the clearance value detected by the second sensor with the preset clearance value.

[0054] It should be noted that the specific magnitude of the preset clearance value is not specifically limited herein and can be set according to the actual situation.

[0055] Further, please refer to Figure 3 , Figure 3 is Figure 2 a schematic diagram of the sub-step process of step S152 in

[0056] Sub-step S1520: If the clearance value is greater than or equal to the preset clearance value, return to the step of obtaining the switch state parameters of the door body detected by the first sensor at a preset time interval.

[0057] In this step, if the clearance value is greater than or equal to the preset clearance value, it is determined that the clearance deviation between the door body and the cabinet body is normal when the door body is in the closed state.

[0058] Sub-step S1521: If the clearance value is less than the preset clearance value, control the clearance adjustment device to adjust the clearance between the bottom of the door body and the bottom of the cabinet body.

[0059] In this step, if the clearance value is less than the preset clearance value, it indicates that when the door body is in the closed state, due to the self-weight of the door body, the clearance between the bottom of the door body and the bottom of the cabinet body becomes smaller, and it is determined that the clearance deviation between the door body and the cabinet body is abnormal at this time, and a clearance adjustment operation is required.

[0060] Further, please refer to Figure 4 and Figure 5 , Figure 4 is a partial structural schematic diagram of the refrigeration device 1 provided in this embodiment, Figure 5 is a schematic diagram of the refrigeration device 1 provided in this embodiment. The clearance adjustment device includes a push rod 12 and a push rod driving member (not shown in the figure) connected to the push rod 12. Among them, the push rod driving member is electrically connected to the control unit. Sub-step S1521 can also be implemented in the following manner.

[0061] First, if the gap value is less than the preset gap value, determine the adjustment parameter of the gap adjustment device based on the difference between the preset gap value and the gap value, and generate an adjustment instruction.

[0062] In this step, the adjustment instruction may include parameters such as the extending direction of the ejector rod 12 and the extending length of the ejector rod 12.

[0063] Next, the ejector rod driving member adjusts the gap between the bottom 110 of the door body and the bottom 100 of the box body by driving the ejector rod 12 based on the adjustment instruction.

[0064] In this embodiment, since the refrigeration device 1 usually includes a plurality of accommodating spaces, the box body 10 at each accommodating space is connected to the corresponding door body 11. Exemplarily, the box body 10 may further include a support rod 101. The ejector rods 12 of the gap adjustment device may be respectively arranged on the support rod 101 and the bottom 100 of the box body. Among them, the ejector rod 12 can extend and retract relative to the plane where the support rod 101 and the bottom 100 of the box body are located, so as to make the gap between the door body 11 and the box body 10 at this accommodating space uniform. The number of ejector rods 12 can be 4, 8, etc. When the number of ejector rods is 4, their distribution is as Figure 4 shown. In addition, for a refrigeration device with a small volume and only one accommodating space, the ejector rod 12 of the gap adjustment device can be directly arranged on the upper part of the box body and the side of the bottom 100 of the box body close to the door body 11. Therefore, the installation position of the ejector rod 12 of the gap adjustment device on the box body 10 is not specifically limited here and can be selected according to the actual situation.

[0065] In this embodiment, the ejector rod driving member drives the ejector rod 12 to extend a preset length in the direction of the door body 11 based on the adjustment instruction, thereby driving the door body 11 to generate a small displacement, realizing precise gap adjustment until the gap value measured by the second sensor between the bottom 100 of the box body and the bottom 110 of the door body reaches the preset gap value, so as to ensure the uniformity of the gap between the bottom 100 of the box body and the bottom 110 of the door body of the refrigeration device 1, and further improve the overall quality of the refrigeration device 1 (such as a push-pull refrigerator).

[0066] Based on the same inventive concept, please refer to Figure 5 , Figure 5Schematic diagram of the functional modules of a door gap adjustment device 20 for a refrigeration device provided in this embodiment. In this embodiment, the door gap adjustment device 20 of the refrigeration device can be divided into functional modules according to the above method embodiment. For example, each functional module can be corresponding to each function, or two or more functions can be integrated into one processing module. The above integrated module can be implemented in the form of hardware or in the form of a software functional module. It should be noted that the division of modules in the embodiments of the present application is schematic, only a logical function division, and there may be other division methods in actual implementation. For example, in the case of dividing each functional module corresponding to each function, Figure 4 The shown door gap adjustment device 20 of the refrigeration device is a schematic diagram of a device. Among them, the door gap adjustment device 20 of the refrigeration device may include a first acquisition module 200, a determination module 210, a control module 220, a second acquisition module 230, and an adjustment module 240.

[0069] The control module 220 is configured to control the working state of the second sensor according to the opening and closing state of the door, where the initial working state of the second sensor is the closed state; In this embodiment, the control module 220 can be used to execute Figure 1 The step S13 shown.

[0070] The second acquisition module 230 is configured to acquire the gap value between the bottom of the cabinet and the door detected by the second sensor when the working state of the second sensor is the start state; In this embodiment, the second acquisition module 230 can be used to execute Figure 1 The step S14 shown. For the specific description of the second acquisition module 230, reference can be made to the description of step S14.

[0071] An adjustment module 240 is configured to control a gap adjustment device to perform gap adjustment according to a gap value.

[0072] In this embodiment, the adjustment module 240 can be used to execute Figure 1 step S15 shown. For the specific description of the adjustment module 240, reference can be made to the description of step S15.

[0073] Furthermore, the control module 220 is specifically configured to: if the door body is in an open state, keep the operating state of the second sensor in a closed state; if the door body is in a closed state, set the operating state of the second sensor to a startup state.

[0074] In this embodiment, the second sensor is started only when the door body is in a closed state, avoiding additional sensor startup and data acquisition operations, thereby saving energy, reducing the energy consumption of the refrigeration device, and also extending the service life of the second sensor.

[0076] In this embodiment, the adjustment module 240 can be used to execute Figure 1 step S15 shown. For the specific description of the adjustment module 240, reference can be made to the description of step S15.

[0077] Furthermore, please refer to Figure 6 , Figure 6 which is a schematic diagram of the refrigeration device 1 provided in this embodiment. An embodiment of the present application further provides a refrigeration device 1, which includes a box body 10, a door body 11 fixedly connected to the box body 10, a gap adjustment device provided on one side of the box body 10 close to the door body 12, and a control unit (not shown in the figure). The door body 11 can move relative to the box body 10, and the box body 10 includes a box body bottom 100.

[0078] The refrigeration device 1 further includes a first sensor (not shown in the figure) and a second sensor (not shown in the figure). The first sensor is disposed inside the cabinet 10 for detecting the opening and closing state of the door body 11. The second sensor is disposed on one side of the bottom 100 of the cabinet close to the door body 11 for detecting the gap between the bottom 100 of the cabinet and the bottom 110 of the door body. The first sensor and the second sensor are electrically connected to the control unit, and the control unit is configured to execute the method for adjusting the gap between the door bodies of the refrigeration device provided in the above method embodiment. In this way, during the production and assembly of the door body of the refrigeration device 1, the method for adjusting the gap between the door bodies of the refrigeration device can ensure that the gap between the cabinet 10 and the door body 11 of the refrigeration device is uniform, thereby improving the overall quality of the refrigeration device 1 (such as, a push-pull refrigerator).

[0079] In summary, a method, a device, and a refrigeration device for adjusting the gap between the door bodies provided in the present application are applied to the control unit of the refrigeration device. First, the opening and closing state parameters of the door body detected by the first sensor are obtained at a preset time interval. Then, the opening and closing state of the door body is determined based on the opening and closing state parameters. Next, the working state of the second sensor is controlled according to the opening and closing state of the door body, where the initial working state of the second sensor is the closed state. Then, when the working state of the second sensor is the starting state, the gap value between the bottom of the cabinet and the bottom of the door body detected by the second sensor is obtained. Finally, the gap adjusting device is controlled to adjust the gap according to the gap value. In the above solution, when the door body of the refrigeration device is in the closed state, the gap value between the bottom of the cabinet and the bottom of the door body is detected in real time by the second sensor, and when a deviation in the gap between the two is detected, the gap is adjusted by the gap adjusting device.
