Hollow glass doors have also been widely used as refrigerator doors. Hollow glass doors can sink due to long-term use or transportation, affecting the user experience.

[0003] Existing Chinese patent number CN104373020B provides a door structure and cabinet that solves the door sinking problem by integrating rollers at the door's bottom with a door support structure. However, there's a long sliding distance between the rollers and the door support structure, which creates friction during the closing process, causing the door to not close tightly, impacting overall performance and even causing a sense of clogging or noise. The only way to ensure tight closure is by increasing the self-closing force of the door closer on the other side.

[0051] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0052] The disclosure below provides many different embodiments or examples for implementing different configurations of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.
[0053] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.
[0054] like Figures 1-8 As shown, an embodiment of the present application provides a door support device for use in refrigeration equipment, which includes a cabinet body 1 and a door body 2 rotatably connected to the cabinet body 1. The door support device is arranged on the cabinet body 1, away from the installation side of the door body 2, and includes a fixing member 3 and a supporting member 4. Specifically, the door body 2 can be connected to the cabinet body 1 via a hinge, so that the door body 2 can be rotated in a horizontal plane to achieve opening and closing. The door support device supports the bottom of the door body 2 away from the hinge, thereby ensuring the stability of the support for the door body 2.
[0055] The fixing member 3 is connected to the cabinet 1. The fixing member 3 includes a fixing portion and a mounting portion connected to the fixing portion, and the fixing portion is fixedly connected to the cabinet.
[0056] The support member 4 is rotatably connected to the fixing member 3, and the support member 4 has a support surface 41 for supporting the door body 2. Specifically, the support member 4 is rotatably connected to the mounting portion of the fixing member 3.
[0057] like Figure 2-5 As shown, the support member 4 can rotate between a first state and a second state. When the support member 4 is in the first state, the support surface 41 forms a guiding slope for guiding the bottom of the door body 2 to move onto the support surface 41; when the support member 4 is in the second state, the support surface 41 forms a supporting plane for supporting the bottom of the door body 2 to keep the door body 2 in a closed state.
[0058] In the present application, by rotatably setting the support member 4 between the first state and the second state, when closing the door, the support surface 41 of the support member 4 forms a guiding slope, which facilitates the door body 2 to slide onto the support surface 41, and the support member 4 rotates as the door body 2 closes until the door body 2 is fully closed. At this time, the support member 4 is in the second state to support the door body 2. In the process of opening and closing the door body 2, the sliding friction between the support member 4 and the door body 2 is reduced through its own rotation, avoiding the door body 2 from closing loosely due to sliding friction and affecting the performance of the entire machine, so that the door closer can ensure the tightness of the door body 2 with a smaller self-closing force, thereby improving the user experience.
[0059] In the related art, the existing door support assembly supports the bottom of the door body 2. During the opening and closing process of the door body 2, there is a long sliding period between the door support assembly and the door body 2. In order to ensure the supporting effect on the door body 2, the interaction force between the door support assembly and the door body 2 is relatively large. The friction generated during the closing process will cause the door body 2 to be not closed tightly, affecting the performance of the entire machine, and even causing a sense of blockage or noise; in order to solve the problem of the door body 2 not closing tightly, the self-closing force of the door closer can only be increased, but increasing the self-closing force of the door closer will increase the effort spent on opening and closing the door body 2, thereby affecting the user experience.
[0060] In the embodiment of the present application, by configuring the support member 4 to be rotatable, when the door body 2 is open, the support member 4 is in a first state, and the support surface 41 forms a guiding slope, which facilitates the bottom of the door body 2 to slide onto the support surface 41. As the door body 2 closes, the support member 4 rotates synchronously, thereby reducing the sliding friction between the support member 4 and the door body 2. When the door body 2 is fully closed, the support member 4 rotates to the second state, supporting the bottom of the door body 2 via the support plane, ensuring the stability of the support for the door body 2. The sliding friction between the support member 4 and the door body 2 is reduced, thereby reducing the sense of obstruction and noise when opening and closing the door body 2, and avoiding the situation where the door body 2 is not closed tightly due to sliding friction. The door closer can ensure the tightness of the door body 2 with a smaller self-closing force, thereby improving the user experience. While ensuring the support effect for the door body 2, it is convenient for the door body 2 to switch from the open state to the fully closed state.
[0061] like Figure 5 As shown, in some embodiments, the support surface 41 includes a support portion 411 and a transition portion 412 that smoothly transitions with the support portion 411 , the transition portion 412 is used to guide the bottom of the door body 2 to move to the support portion 411 , and the support portion 411 is used to support the bottom of the door body 2 .
[0062] In the present application, during the process of closing the door body 2, the bottom of the door body 2 first abuts against the transition portion 412. As the door body 2 closes, the support member 4 rotates so that a small sliding distance exists between the bottom of the door body 2 and the transition portion 412. When the door body 2 is fully closed, the bottom of the door body 2 slides to the support portion 411, and the support portion 411 supports the door body 2 to ensure the support effect of the door body 2. During the process of opening the door body 2, as the door body 2 opens, the rotation in the support frame reduces the sliding distance between the bottom of the door body 2 and the support portion 411. Moreover, the rotation of the support member 4 can also increase the gap between the support surface 41 and the bottom of the door body 2 to reduce frictional resistance, until the door body 2 is fully opened and the bottom of the door body 2 is separated from the support member 4.
[0063] In one embodiment, the supporting portion 411 and the transition portion 412 are located on the same plane.
[0064] In this application, by arranging the support part 411 and the transition part 412 on the same plane, the processing and forming of the support member 4 is facilitated, and the support part 411 and the transition part 412 are transitioned through a plane, which facilitates the transition of the door body 2 between the support part 411 and the transition part 412.
[0065] In another embodiment, the plane where the support portion 411 is located and the plane where the transition portion 412 is located are arranged at an angle.
[0066] In the present application, the support portion 411 and the transition portion 412 can also be set at an angle, and it is only necessary to ensure that the transition portion 412 of the support surface 41 can form a guiding inclined surface in the first state, and the support portion 411 of the support surface 41 can form a supporting plane in the second state. Specifically, the support portion 411 and the transition portion 412 form an obtuse angle. When the support member 4 is in the first state, the guiding inclined surface of the transition portion 412 is used for the door body 2 to slide onto the support surface 41. When the door body 2 is fully closed, the support portion 411 forms a supporting plane to support the door body 2. At this time, the transition surface can have a certain limiting effect on the door body 2, thereby ensuring the tightness of the door body 2. Moreover, when the door body 2 is opened, the transition portion 412 will not cause resistance to the opening of the door body 2 due to the rotation of the support member 4. Optionally, the angle formed between the support portion 411 and the transition portion 412 can be greater than 180°. In this way, even if the support member 4 cannot rotate due to a malfunction, a guide slope can be formed in the transition portion 412 to slide the bottom of the door body 2 from the transition portion 412 to the support portion 411.
[0067] In some embodiments, the support member 4 and the fixing member 3 are rotatably connected via a rotating shaft 5 , the transition portion 412 is adjacent to the rotating shaft 5 , and the support portion 411 is away from the rotating shaft 5 .
[0068] In the present application, the transition portion 412 is adjacent to the rotating shaft 5, so that when the bottom of the door body 2 contacts the transition portion 412, the support member 4 can rotate smoothly, thereby reducing the sliding friction between the door body 2 and the transition portion 412 through the rotation of the support member 4; when the door body 2 is fully closed, the support portion 411 supports the bottom of the door body 2. Since the support portion 411 is far away from the rotating shaft 5, the stability of the support member 4 in the second state is improved, and the support effect on the door body 2 can be guaranteed.
[0069] In some embodiments, the support member 4 switches from the second state back to the first state by its own gravity.
[0070] In this application, the self-part can be switched from the second state back to the first state by its own gravity. When the door body 2 is opened, the support part 4 is separated from the door body 2 and is no longer subjected to the pressure of the door body 2. It flips to the first state by its own gravity to guide the door body 2 when it is closed next time.
[0071] In another embodiment, the door support device further includes an elastic member, two ends of which respectively abut against the fixing member 3 and the supporting member 4 to provide elastic force for the supporting member 4 to switch from the second state back to the first state.
[0072] In the present application, an elastic member is provided, which may be a spring or a spring sheet, and the elastic force of the elastic member assists the support member 4 in switching from the second state back to the first state, thereby effectively avoiding the situation where the support member 4 cannot smoothly switch back to the first state due to uneven rotation due to long-term use, thereby ensuring the reliability of the door support device.
[0073] In some embodiments, during the closing process of the door body 2 , the support member 4 switches from the first state to the second state under the pressure of the door body 2 .
[0074] In the present application, during the closing process of the door body 2, the bottom of the door body 2 abuts against the transition portion 412 of the support surface 41. As the door body 2 closes, the bottom of the door body 2 generates a force on the support surface 41, thereby pushing the support member 4 to rotate until the support member 4 rotates to the second state. At this time, the door body 2 is fully closed, and the support portion 411 supports the door body 2. During the closing process of the door body 2, the rotation of the support member 4 is driven by the door body 2, thereby ensuring that the support member 4 can rotate synchronously during the closing process of the door body 2 to reduce the sliding friction between the door body 2 and the support member 4.
[0075] like Figure 3 As shown, in some embodiments, the support member 4 has a first abutting portion 42 , and the fixing member 3 is provided with a first limiting portion 31 for limiting the first abutting portion 42 , so that the support member 4 remains in the first state.
[0076] In this application, when the support member 4 rotates to the first state, the first limiting portion 31 abuts against the first abutting portion 42 to complete the limiting of the support member 4, so that the support member 4 remains in the first state, so as to guide the door body 2 well when closing the door body 2.
[0077] like Figure 4 As shown, in some embodiments, the support member 4 has a second abutting portion 43 , and the fixing member 3 is provided with a second limiting portion 32 for limiting the second abutting portion 43 , so that the support member 4 remains in the second state.
[0078] In this application, when the support member 4 rotates to the second state, the second limiting portion 32 abuts against the second abutting portion 43 to complete the limiting of the support member 4, so that the support frame can be maintained in the second state, providing good and stable supporting force for the door body 2.
[0079] like Figure 4 and 6As shown, in some embodiments, a heating component is provided on the door body 2, and a trigger switch 6 is provided at the bottom of the door body 2. The trigger switch 6 is electrically connected to the heating component through a controller. The door support device also includes a trigger member 7 provided on the support member 4, and the trigger member 7 is used to trigger the trigger switch 6; when the support member 4 is in the second state, the trigger member 7 triggers the trigger switch 6 to put the trigger switch 6 in the on state; when the support member 4 is in the first state, the trigger member 7 is disengaged from the trigger component to put the trigger switch 6 in the off state.
[0080] Specifically, the door body 2 adopts a hollow glass door. In order to prevent condensation on the hollow glass, a heating component is generally provided on the door body 2, and the heating component is used to prevent condensation on the door body 2. In the present application, by coordinating the trigger switch 6 with the trigger member 7 on the door support device, when the door body 2 is in the open state, the support member 4 is in the first state, at which time the trigger switch 6 is in the disconnected state, and the controller controls the working state of the heating component through the controller according to the disconnected state of the trigger switch 6, thereby adjusting the situation of preventing condensation on the door body 2; when the door body 2 is in the fully closed state, the support member 4 is in the second state, at which time the trigger switch 6 is in the connected state, and the controller controls the working state of the heating component through the controller according to the connected state of the trigger switch 6, thereby adjusting the situation of preventing condensation on the door body 2. Thus, the working state of the heating component is adjusted according to the switch state of the door body 2, while ensuring the anti-condensation effect, the energy consumption of the heating component is balanced, and the overall energy consumption of the refrigeration equipment is reduced.
[0081] Specifically, when the door body 2 is opened, it is necessary to increase the power of the heating component or extend the time the heating component is turned on. When the door body 2 is closed, the power of the heating component can be appropriately reduced or the time the heating component is turned on can be shortened to ensure anti-condensation while reducing the energy consumption of the heating component.
[0082] Specifically, the trigger switch 6 is a magnetically controlled switch, and the trigger member 7 is a magnet. When the door 2 is closed, the distance between the magnet and the magnetically controlled switch is closest, thereby triggering the trigger switch 6. When the door 2 is opened, the distance between the magnet and the magnetically controlled switch becomes farther, thereby disconnecting the trigger switch 6. The trigger switch 6 can be turned on and off without the trigger member 7 making contact, which can effectively protect the trigger switch 6 and the trigger member 7.
[0083] Optionally, the trigger switch 6 and the trigger member 7 may also be configured as other forms of travel switches, such as distance sensors.
[0084] In some embodiments, a mounting groove 44 is provided on a side of the support member 4 away from the support surface 41 , and the trigger member 7 is installed in the mounting groove 44 .
[0085] In the present application, by arranging the trigger member 7 in the installation groove 44 away from the support surface 41, that is, below the support member 4, the trigger member 7 will not come into contact with or rub against other structures, thereby improving the protection of the trigger member 7.
[0086] like Figure 3 and 4 As shown, in some embodiments, the door support device further includes a cover plate 8 installed at the notch of the installation slot 44 to limit the trigger member 7 in the installation slot 44.
[0087] In the present application, by providing a cover plate 8 at the notch of the mounting slot 44 , the protection of the trigger member 7 can be further improved, thereby preventing the trigger member 7 from falling off due to loose fixation, thereby improving the reliability of use.
[0088] The door support device is configured so that the support member 4 can rotate between a first state and a second state. When closing the door, the support surface 41 of the support member 4 forms a guiding slope, which facilitates the door body 2 to slide onto the support surface 41. The support member 4 rotates as the door body 2 closes until the door body 2 is fully closed. At this time, the support member 4 is in the second state to support the door body 2. During the process of opening and closing the door body 2, the sliding friction between the support member 4 and the door body 2 is reduced through its own rotation, thereby preventing the door body 2 from closing loosely due to sliding friction and affecting the performance of the entire machine. As a result, the door closer can ensure the tightness of the door body 2 with a smaller self-closing force, thereby improving the user experience.
[0089] An embodiment of the present application provides a refrigeration device, comprising: a cabinet body 1 and a door body 2 rotatably connected to the cabinet body 1; and the above-mentioned door support device.
[0090] In this application, the refrigeration equipment is a refrigerator, and the door body 2 is supported by a door support device to prevent the door body 2 from sinking during transportation or use. The support member 4 of the door support device can be rotatable, which can effectively reduce the sliding friction between the door body 2 and the door support device during the opening and closing process, thereby ensuring the tightness of the door body 2. The tightness of the door body 2 can be ensured without increasing the self-closing force of the door closer, and the effort spent on opening and closing the door is less, which improves the user experience.
[0091] In some embodiments, a roller 9 is rotatably provided at the bottom of the door body 2 , and the roller 9 is used to abut against the support surface 41 of the door support device.
[0092] In the present application, the roller 9 is rotatably arranged at the bottom of the door body 2, and part of the roller 9 protrudes to the bottom surface of the door body 2, which can cooperate with the support surface 41 of the support member 4, and can further reduce the friction between the door body 2 and the support member 4. In conjunction with the rotation of the support member 4, the sliding distance between the door body 2 and the support member 4 can also be shortened, making it convenient for the door body 2 to switch between the open state and the fully closed state.
[0093] In some embodiments, a heating assembly is provided on the door body 2, and a trigger switch 6 is provided at the bottom of the door body 2. The trigger switch 6 is electrically connected to the heating assembly (not shown) through a controller (not shown). The door support device also includes a trigger member 7 provided on the support member 4, and the trigger member 7 is used to trigger the trigger switch 6; when the support member 4 is in the second state, the trigger member 7 triggers the trigger switch 6 to make the trigger in the on state; when the support member 4 is in the first state, the trigger member 7 is disengaged from the trigger assembly to make the trigger switch 6 in the off state; wherein the controller controls the opening and closing of the heating assembly according to the state of the trigger switch 6.
[0094] In the present application, the opening and closing states of the door body 2 are linked to the operation of the heating component through the cooperation of the trigger switch 6 and the trigger member 7, that is, the cooperation of the door support device and the trigger switch 6 enables the controller to control the working state of the heating component according to the opening and closing conditions of the door body 2, thereby realizing the adjustment of the working state of the heating component when the door body 2 is in different states or different opening times, opening times, and opening times per unit time, thereby ensuring the anti-condensation effect while reducing the energy consumption of the heating component.
[0095] Specifically, when the door body 2 is in the open state, the controller controls the heating component to operate at maximum power or at the maximum on-off rate, where the on-off rate refers to the proportion of time that the heating component is in the on state per unit time; when the door body 2 is in the closed state, the controller controls the heating component to operate at a lower power or a lower on-off rate.
[0096] Specifically, the roller 9 and the trigger switch 6 are both arranged at the bottom of the door body 2. The length of the roller 9 protruding from the bottom of the door body 2 is greater than the length of the trigger switch 6 protruding, and the trigger component can also be protected so that the trigger component will not contact the support surface 41.
[0097] In some embodiments, the controller controls the on-off rate of the heating component according to the length of time the trigger switch 6 is in the off state.
[0098] In a specific embodiment, the controller controls the on-off rate of the heating component according to the duration of a single off state of the trigger switch 6, that is, adjusts the on-off rate of the heating component according to the length of a single opening time of the door body 2.
[0099] In another specific embodiment, the on-off rate of the heating component is controlled according to the total time that the trigger switch 6 is in the off state per unit time, that is, the on-off rate of the heating component is adjusted according to the cumulative opening time of the door body 2 per unit time.
[0100] In summary, the working state of the heating component can be adjusted more accurately according to the opening state of the door body 2, thereby further reducing the energy consumption of the heating component while ensuring the anti-condensation effect.
[0101] In some embodiments, the controller controls the on-off rate of the heating component according to the number of switching between the on state and the off state of the trigger switch 6 per unit time.
[0102] In this application, the controller controls the on-off rate of the heating component according to the number of times the trigger switch 6 switches between the on state and the off state per unit time, that is, the on-off rate of the heating component is controlled according to the number of times the door body 2 is opened or closed per unit time, thereby further reducing the energy consumption of the heating component while ensuring the anti-condensation effect.
[0103] In some embodiments, the trigger switch 6 is electrically connected to a lighting lamp (not shown) of the refrigeration device. When the trigger switch 6 is in an off state, the lighting lamp is turned on, and when the trigger switch 6 is in an on state, the lighting lamp is turned off.
[0104] In the present application, the trigger switch 6 can also control the on and off of the lighting. When the door body 2 is opened, the trigger switch 6 is disconnected, and the lighting is turned on. When the door body 2 is fully closed, the trigger switch 6 is connected, and the lighting is turned off. The control module of the lighting can be integrated into the door support device, and there is no need to set a special control module for controlling the on and off of the lighting on the cabinet body 1. In addition, the control accuracy can be guaranteed. When the door body 2 is not closed tightly, the trigger switch 6 is still in the disconnected state, that is, the lighting is still on, which can provide the user with a sense that the door body 2 is not closed tightly.
[0105] The present invention provides a method for controlling a refrigeration device, including:
[0106] S1, obtain the switch status of door 2;
[0107] S2, when the door body 2 is in the open state, controlling the heating component on the door body 2 to operate at a first on-off rate;
[0108] S3. When the door body 2 is in a closed state, the heating component is controlled to operate at a second on-off rate, which is smaller than the first on-off rate.
[0109] Specifically, the first on-off rate is the maximum on-off rate of 100%, that is, the heating component is always in the on state. When the door body 2 is in the open state, the heating component operates at the maximum on-off rate. The second on-off rate is the normal operating state of the heating component. Specifically, the second on-off rate can be 50%-60%, that is, the heating component is on for 50%-60% of the unit time.
[0110] In some embodiments, the control method further includes:
[0111] S4, obtaining the duration that the door body 2 is in the open state;
[0112] S5. When the door 2 is in the open state for a period longer than the first preset period, after the door 2 is closed, the heating component is controlled to operate at a third on-off rate for the first period, and time information of the door 2 opening and closing is reset, wherein the third on-off rate is greater than the second on-off rate and less than the first on-off rate;
[0113] S6. When the duration that the door body 2 is in the open state is less than the first preset duration, after the door body 2 is closed, the heating component is kept running at the second on-off rate.
[0114] Specifically, when the door 2 is open for a duration greater than a first preset duration, i.e., the duration of a single opening of the door 2 exceeds the first preset duration, after the door 2 is closed, the heating component operates at the third on-off rate for the first duration, and then recalculates the time information of the opening and closing of the door 2. When the duration of the door 2 remaining open does not exceed the first preset duration, after the door 2 is closed, the heating component operates at the original first on-off rate.
[0115] Optionally, when the door body is in the open state for a time period greater than a third preset time period, after the door body 2 is closed, the heating component is controlled to operate at the first on-off rate for a fourth time period, and the time information of the door body 2 opening and closing is reset.
[0116] In some embodiments, the control method further includes:
[0117] S7, obtaining the number of times door 2 is opened per unit time;
[0118] S8, when the number of times the door body 2 is opened per unit time is greater than a preset value, after the door body 2 is closed for the last time per unit time, controlling the heating component to operate at a fourth on-off rate for a second time period, and resetting the number of times the door body 2 is opened and closed, wherein the fourth on-off rate is greater than the second on-off rate and less than the first on-off rate;
[0119] S9. When the number of times the door body 2 is opened per unit time is less than a preset value, after the door body 2 is closed for the last time per unit time, the heating component is kept running at the second on-off rate.
[0120] Specifically, when the number of times door 2 is opened per unit time exceeds a preset value, after door 2 is closed for the last time, the operating state of the heating component is switched to the fourth on-off rate, and after running for a second time, the number of times door 2 is opened and closed is reset. When the number of times door 2 is opened per unit time is less than a preset value, the heating component maintains operation at the second on-off rate.
[0121] In some embodiments, the control method further includes:
[0122] S10, obtaining the cumulative opening time of door 2 per unit time;
[0123] S11, when the cumulative door opening time of the door body 2 per unit time is greater than the second preset time, after the door body 2 is closed for the last time within the unit time, controlling the heating component to operate at a fifth on-off rate for a third time, and resetting the time information of the door body 2 opening and closing, wherein the fifth on-off rate is greater than the second on-off rate and less than the first on-off rate;
[0124] S12: When the accumulated opening time of the door body 2 per unit time is less than the second preset time, the heating component is kept running at the second on-off rate after the door body 2 is closed for the last time per unit time.
[0125] Specifically, when the cumulative door opening time per unit time of door 2 exceeds the second preset time, after door 2 is closed, the heating component operates at the fifth on-off rate for the third time, and the time information of the opening and closing of door 2 is reset. When the cumulative door opening time per unit time of door 2 is less than the second preset time, after door 2 is closed, the heating component maintains the original second on-off rate.
[0126] In this application, the duration of a single door opening, the cumulative door opening time per unit time, and the number of door openings per unit time are all monitored simultaneously. The heating component's operating state is adjusted based on whichever standard is met, and the information on the duration of the door opening, the cumulative door opening time per unit time, and the number of door openings per unit time are all reset. When both standards are met simultaneously, the heating component operates with a higher on-off rate and a longer operating time to ensure the anti-condensation effect.
