Description

Technical Field

[0001] The present application belongs to the field of refrigeration technology, and in particular to a storage device. Background Art

[0002] Whether it is a refrigerator or a freezer, both are devices that preserve food and other items at low temperatures and are widely used in all walks of life. However, since the air inside the freezer will cool down quickly after the door is closed, on the one hand, it is easy to cause partial deformation of the door and cause a gap between the sealing strip and the cabinet body. When the cold air inside the cabinet contacts the outside of the cabinet through the gap, condensation or even ice will be generated; on the other hand, the pressure inside the cabinet will decrease accordingly as the temperature inside the cabinet decreases, so that a certain pressure difference will be formed between the inside and outside of the cabinet, both of which will cause the door to be unable to be opened quickly.

[0039] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0040] Reference below Figure 1-Figure 4 The storage device provided in an embodiment of the present application is described, and the storage device includes a cabinet body 100, a door body 200, a door seal 300, a second magnetic member 400 and a connecting device 500.

[0041] The cabinet 100 has a cabinet opening 110. The material of the cabinet 100 includes but is not limited to hard plastic, stainless steel, aluminum alloy or titanium alloy, etc. It should be noted that the number, shape and specific distribution of the cabinet opening 110 can be designed according to actual conditions, and this embodiment does not impose specific restrictions on this.

[0042] In this embodiment, the cabinet opening 110 is arranged upwards to facilitate users to put in and take out items. Decorative parts such as a deodorizing box, a sterilizing lamp, a lighting lamp, or a temperature adjustment knob may also be arranged in the cabinet 100. There is no specific limitation on this in the embodiment of the present application. Furthermore, the inner side wall of the cabinet 110 is also provided with a protective layer to prevent scratches.

[0043] The door body 200 is installed on the cabinet body 100. The material of the door body 200 includes but is not limited to hard plastic, stainless steel, aluminum alloy or titanium alloy. It should be noted that the door body 200 corresponds to the cabinet opening 110 one by one, and the shape and size of the door body 200 can be designed according to the cabinet opening 110, and this embodiment does not impose specific restrictions on this.

[0044] It can be understood that one side of the door body 200 is pivotally connected to the cabinet body 100 so that the other side of the door body 200 can selectively abut against the cabinet body 100, thereby realizing that the door body 200 has two states of opening and closing.

[0045] The door seal 300 is installed on the door body 200, and the door seal 300 is used to seal with the cabinet opening 110, and the door seal 300 is provided with a first magnetic member. The door seal 300 can be made of a material with a certain elasticity such as rubber. The connection method between the door seal 300 and the door body 200 includes but is not limited to gluing. The connection method between the first magnetic member and the door seal 300 includes but is not limited to gluing.

[0046] It should be noted that the storage equipment in the embodiment can be understood as a broad refrigeration storage equipment, including but not limited to refrigerators, freezers, display cabinets, beverage cabinets, wine cabinets, cold cabinets, and refrigeration vending machines. The storage equipment has various structural forms and a wide range of applications. As a specific example, the freezer is used as a specific example in the embodiment of the present application. That is, to ensure the refrigeration effect of the freezer, when the door body 200 is closed, the door seal 300 is pressed by the door body 200 on the periphery of the cabinet opening 110, thereby ensuring a low temperature environment in the cabinet body 100.

[0047] It can be understood that since the cabinet opening 110 in this embodiment faces upward, that is, the freezer is a horizontal freezer, the sealing performance of the door seal 300 to the cabinet opening 110 can be further improved under the action of gravity of the door body 200 .

[0048] The second magnetic member 400 is installed on the cabinet 100 and is close to the cabinet opening 110. The connection between the second magnetic member 400 and the cabinet 100 includes but is not limited to a snap connection or a threaded connection.

[0049] The connecting device 500 is connected to at least one of the first magnetic member and the second magnetic member 400. The connecting device 500 has a first state in which an attractive force is generated between the first magnetic member and the second magnetic member 400 when the door body 200 is closed, and a second state in which a repulsive force is generated between the first magnetic member and the second magnetic member 400 when a trigger signal for opening the door is received.

[0050] It can be understood that, on the one hand, when the door body 200 is closed, even if there is a problem of partial deformation of the door body 200, the connecting device 500 can generate an attractive force between the first magnetic member arranged on the door seal 300 and the second magnetic member 400 arranged on the cabinet 100, so as to achieve a sealed connection between the door seal 300 and the cabinet 100, thereby ensuring that the temperature inside the cabinet 100 can be maintained at a relatively low temperature as much as possible, thereby extending the storage time of the items placed in the cabinet 100 and avoiding condensation from affecting the user's opening of the door; on the other hand, considering that when the door body 200 is closed, the air pressure inside the cabinet 100 is much lower than the air pressure outside the cabinet 100, when the door body 200 needs to be opened, the connecting device 500 is used to generate a repulsive force between the first magnetic member and the second magnetic member 400, so that the first magnetic member drives the door seal 300 away from the cabinet 100, so that the door body 200 has a tendency to open, thereby assisting the user to quickly open the door body 200, reducing the difficulty of the user opening the door, and improving the user experience.

[0051] According to the storage device provided in the embodiment of the present application, when the door body 200 is closed, even if the door body 200 is partially deformed, an attraction force is generated between the first magnetic component provided on the door seal 300 and the second magnetic component 400 provided on the cabinet 100 through the connecting device 500, thereby achieving a sealed connection between the door seal 300 and the cabinet 100. When the door body 200 needs to be opened, the mutual repulsion force generated between the first magnetic component and the second magnetic component 400 is utilized by the connecting device 500, so that the first magnetic component drives the door seal 300 away from the cabinet 100, and the door body 200 has a tendency to open, thereby assisting the user to quickly open the door body 200, reducing the difficulty of the user opening the door, and improving the user experience.

[0052] In some embodiments, Figure 2 As shown, one side of the door body 200 is pivotally connected to the cabinet body 100 , and at least part of the first magnetic member is located in the middle of the door seal 300 corresponding to the other side of the door body 200 .

[0053] It is understandable that, considering that evaporators are provided around the inner walls of the current cabinet 100 to play the role of cooling and dehumidification, the temperature at the periphery of the door body 200 corresponding to the evaporator is also lower than the temperature of the rest of the door body 200, resulting in serious deformation of the middle part of the door body 200. Based on the fact that one side of the door body 200 is pivotally connected to the cabinet 100 through a hinge, that is, the sealing between the side of the door body 200 with the hinge and the cabinet 100 can be guaranteed under the pre-tightening force of the hinge, at least part of the first magnetic part is located in the middle of the door body 200 on the other side of the door body 200, which can increase the contact area between the entire door seal 300 and the cabinet opening 110 as much as possible, thereby ensuring the sealing and reducing energy consumption.

[0054] In this embodiment, the first magnetic member is located in the middle of the door seal 300 on the other side of the door body 200 where the hinge is provided. Of course, in other embodiments, if the manufacturing and maintenance costs are not considered, since the door body 200 is often a quadrilateral structure, the middle of the door seal 300 corresponding to the other three sides of the door body 200 where no hinge is provided has a first sealing member, so as to further improve the sealing effect of the cabinet opening 110.

[0055] In some embodiments, Figure 2 As shown, a mounting cavity is provided on the side of the door seal 300 facing the cabinet 100, and the first magnetic member is mounted in the mounting cavity. The connection relationship between the first magnetic member and the mounting cavity includes but is not limited to bonding. It should be noted that the specific shape and size of the mounting cavity can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0056] It can be understood that by setting the installation cavity on the side of the door seal 300 close to the cabinet 100, the first magnetic part is made as close to the second magnetic part 400 as possible. On the one hand, it is ensured that when the door body 200 needs to be opened, the repulsive force generated by the connecting device 500 can move the first magnetic part to a position close to the door body 200, thereby driving the door seal away from the cabinet 100 or even deforming it, so that there is a gap between the side of the door seal 300 close to the cabinet 100 and the cabinet 100, thereby ensuring that the internal and external gases of the cabinet 100 can be exchanged through the gap, so as to achieve the effect of balancing the air pressure inside and outside the cabinet 100, thereby improving the effect of assisting the user to open the door; on the other hand, when the door body 200 is closed, the attractive force generated by the connecting device 500 can move the first magnetic part to a position as close to the cabinet 100 as possible, thereby ensuring that the contact area between the door seal 300 and the cabinet 100 is as large as possible, thereby improving the sealing performance.

[0057] In this embodiment, the installation cavity is provided through the length direction of the door seal 300 to facilitate installation of the first magnetic member.

[0058] In some embodiments, Figure 2 As shown, the first magnetic member includes a magnet, and the second magnetic member 400 includes an electromagnetic coil, wherein the connecting device 500 is configured to change the current direction of the electromagnetic coil.

[0059] It can be understood that the electromagnetic coil is always energized, that is, when the door body 200 is closed, the connecting device 500 controls the current flowing through the electromagnetic coil to be in a first direction, so that an attraction force is generated between the electromagnetic coil and the magnet, so that the magnet drives the door seal 300 close to the cabinet 100, so that the door seal 300 is in as close contact with the cabinet 100 as possible; when the door body 200 needs to be opened, the connecting device 500 controls the current flowing through the electromagnetic coil to be in a second direction opposite to the first direction, so that a repulsive force is generated between the electromagnetic coil and the magnet, so that the magnet drives the door seal 300 away from the cabinet 100, thereby playing a role in assisting the door opening.

[0060] In some embodiments, projections of the magnet and the electromagnetic coil in the direction of the cabinet opening 110 at least partially overlap.

[0061] It can be understood that by making the projection of the magnet on the cabinet 100 and the projection of the electromagnetic coil on the cabinet 100 at least partially overlap, it is ensured that the attraction or repulsion generated by the electromagnetic coil is directly facing the magnet, thereby improving the effect on the magnet as much as possible, making full use of the attraction or repulsion, and improving the corresponding sealing effect and auxiliary door opening effect.

[0062] In this embodiment, the projection of the magnet on the cabinet 100 and the projection of the electromagnetic coil on the cabinet 100 completely overlap, that is, the length of the first magnetic member is the same as the length of the second magnetic member 400, so that the attraction or repulsion between the two is maximized.

[0063] In some embodiments, the door seal 300 and the first magnetic member may also be integrated, that is, the door seal 300 is a rubber magnet, so as to reduce the assembly process.

[0064] In some embodiments, Figure 2 and Figure 3 As shown, the connection device 500 is installed in the cabinet 100, and the second magnetic member 400 further includes a storage box 410 and a wire portion 420. The storage box 410 is installed in the cabinet 100, and a part of the electromagnetic coil is installed in the storage box 410; the wire portion 420 is installed in the storage box 410, and the other part of the electromagnetic coil passes through the wire portion 420 and is electrically connected to the connection device 500. The wire portion 420 is made of insulating materials such as plastic or rubber. The connection method between the wire portion 420 and the storage box 410 includes but is not limited to welding, threaded connection and clamping.

[0065] It is understandable that the storage box 410 is provided with a receiving cavity 411 with an upper opening, so that the electromagnetic coil can be placed in the receiving cavity 411 from the upper side of the opening, thereby supporting and receiving the electromagnetic coil, and reducing the obstacles between the electromagnetic coil and the magnet. At the same time, the lower bottom surface of the storage box 410 is provided with a mounting hole connected to the receiving cavity 411, and one end of the wire portion 420 is installed at the mounting hole, so that both ends of the electromagnetic coil pass through the wire portion 420 through the mounting hole and then are connected to the connecting device 500 through the other end of the wire portion 420, that is, the wire portion 420 guides and protects the end of the electromagnetic coil. It should be noted that the shape and size of the receiving cavity 411 and the shape, size and number of the mounting hole and the wire portion 420 can be designed according to actual needs, and this embodiment is limited to this.

[0066] In this embodiment, Figure 2 As shown, the connection device 500 is located directly below the storage box 410 to facilitate wiring. The connection device 500 includes an electrically connected main control board and a power supply, the power supply is connected to the electromagnetic coil, and the main control board controls the current direction of the power supply to change the magnetic pole generated by the electromagnetic coil, so that the electromagnetic coil and the magnet attract or repel each other.

[0067] In some embodiments, the storage box 410 is made of flame retardant materials to ensure the safety of the entire storage device. The flame retardant materials include but are not limited to aluminum hydroxide, rubber, and epoxy resin.

[0068] In some embodiments, Figure 2 and Figure 4As shown, the cabinet body 100 includes an abutment portion 120 arranged around the cabinet opening 110, the side of the door seal 300 away from the door body 200 is sealed with one side of the abutment portion 120, and the other side of the abutment portion 120 is provided with a mounting member 121, and the storage box 410 is detachably connected to the mounting member 121. The connection method between the mounting member 121 and the abutment portion 120 includes but is not limited to welding and threaded connection. The material of the mounting member 121 includes but is not limited to hard plastic, stainless steel, aluminum alloy or titanium alloy, etc.

[0069] It is understandable that in order to facilitate the positioning of the storage box 410, the upper surface of the abutment portion 120 abuts against the door seal 300 to seal the cabinet opening 110, and the lower surface of the abutment portion 120 is provided with a mounting part 121 detachably connected to the storage box 410 to facilitate subsequent disassembly and maintenance.

[0070] In some embodiments, Figures 2 to 4 As shown, the mounting member 121 forms a mounting groove 1211 with one end open, and the opening is opposite to the cabinet opening 110, and the outer wall of the storage box 410 is snap-fitted with the inner wall of the mounting groove 1211. It should be noted that the size and shape of the mounting groove 1211 can be designed according to actual needs, and this embodiment is not limited to this.

[0071] It is understandable that, since the opening of the mounting member 121 faces the opposite direction to the cabinet opening 110, that is, the cabinet opening 110 faces upward and the opening faces downward, the storage box 410 can be directly snapped into the mounting groove 1211 from bottom to top, thereby avoiding interference between the mounting member 121 and the wire portion 420 when installing the second magnetic member 400. At the same time, since the outer wall of the storage box 410 and the inner wall of the mounting groove 1211 are snapped, a detachable connection can be achieved while maximizing the speed of disassembly and assembly.

[0072] In some embodiments, Figure 3 and Figure 4 As shown, one of the storage box 410 and the mounting member 121 is provided with at least one buckle 412, and the other of the storage box 410 and the mounting member 121 is provided with at least one slot 1212, and the buckles 412 correspond to and are engaged with the slots 1212 one by one.

[0073] It can be understood that by providing a buckle 412 on one of the outer wall of the storage box 410 and the inner wall of the installation groove 1211 and providing a slot 1212 on the other, a snap connection between the two is achieved.

[0074] In this embodiment, the buckle 412 is protruded from the storage box 410 , and the locking slot 1212 is formed in the mounting member 121 and communicates with the mounting slot 1211 .

[0075] In some embodiments, Figure 3As shown, a guide slope 4121 is provided on the side of the buckle 412 away from the storage box 410. The guide slope 4121 is inclined downward, which not only facilitates the storage box 410 to slide into the installation slot 1211 from below, but also plays a role of reverse limit, that is, the lower surface of the buckle 412 abuts against the inner bottom surface of the slot 1212, ensuring the stability of the connection between the two. It should be noted that the number, shape and specific distribution of the buckle 412 and the corresponding slot 1212 can be designed according to actual needs, and this embodiment is not limited to this.

[0076] In some embodiments, the storage device further includes a handle and a pressure sensor, wherein the handle is mounted on the door body 200; the pressure sensor is mounted on the handle and is communicatively connected to the connection device 500. The material of the handle includes but is not limited to hard plastic, stainless steel, aluminum alloy or titanium alloy. It should be noted that the shape and size of the handle can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0077] It should be noted that a pressure sensor is a device or apparatus that can sense pressure signals and convert pressure signals into usable output electrical signals according to certain rules. A pressure sensor is usually composed of a pressure sensitive element and a signal processing unit. Pressure sensors include but are not limited to gauge pressure sensors, differential pressure sensors, and absolute pressure sensors.

[0078] It can be understood that when the door needs to be opened, the user presses the handle, the pressure sensor detects the pressure signal and sends it to the main control board of the controller. After receiving the pressure signal, the main control board sends a control signal to the power supply to change the direction of the current, so that a repulsive force is generated between the electromagnetic coil and the magnet, making it easier to open the door.

[0079] In other embodiments, the storage device further includes an infrared sensor, which is mounted on the handle and is communicatively connected to the connecting device 500 .

[0080] It should be noted that infrared sensors refer to sensors that use the physical properties of infrared rays for measurement. Infrared rays, also known as infrared light, have properties such as reflection, refraction, scattering, interference, and absorption. Any substance, as long as it has a certain temperature (above absolute zero), can radiate infrared rays. When measuring, infrared sensors do not directly contact the object being measured, so there is no friction, and they have the advantages of high sensitivity and fast response. Infrared sensors include optical systems, detection elements, and conversion circuits. Optical systems can be divided into two types according to their structures: transmission and reflection. Detection elements can be divided into thermal detection elements and photoelectric detection elements according to their working principles. The most commonly used thermistor is thermistor. When thermistor is radiated by infrared rays, the temperature rises and the resistance changes (this change may be larger or smaller, because thermistors can be divided into positive temperature coefficient thermistors and negative temperature coefficient thermistors), which are converted into electrical signals through the conversion circuit for output. Photoelectric detection elements commonly used are photosensitive elements, which are usually made of materials such as lead sulfide, lead selenide, indium arsenide, antimony arsenide, cadmium mercury telluride ternary alloy, germanium and silicon doping.

[0081] It can be understood that when the door needs to be opened, the user presses the handle, the infrared sensor detects the temperature increase and sends it to the main control board of the controller. After receiving the pressure signal, the main control board sends a control signal to the power supply to change the direction of the current, so that a mutual repulsion force is generated between the electromagnetic coil and the magnet, making it easier to open the door.

[0082] It should be noted that the handle may be installed with both a pressure sensor and an infrared sensor, or only one of the pressure sensor and the infrared sensor may be installed, and this embodiment does not impose any specific limitation on this.

[0083] In this embodiment, Figure 1 , Figure 2 and Figure 4 As shown, the handle includes a handle groove 600 opened on one side of the door body 200 to improve the aesthetics. It should be noted that the size and shape of the handle groove 600 can be designed according to actual needs, and this embodiment is not limited to this.
