[0001] The utility model relates to the technical field of household appliances, and more specifically, to a facial mask heating assembly, a door body and a refrigerator. Background Art

[0002] In order to bring a better experience to users, the door body of a beauty refrigerator can be equipped with a device for heating facial masks. However, for the beauty refrigerators equipped with facial mask heaters on the market currently, generally, the facial mask is placed between the door body and the facial mask fixing cover, and the facial mask is clamped and fixed by the door body and the facial mask fixing cover so that the facial mask is closely attached to the heating surface for heating.

[0003] For example, Chinese Patent No. CN212778174U discloses a refrigerator door and a refrigerator. The refrigerator door includes: a door body, an object placing area is arranged on the outer side of the door body, and a heating device is also arranged on the door body to heat the articles placed in the object placing area; a baffle plate, the baffle plate is movably installed on the outer side of the door body facing outward, when the baffle plate moves to the first position, the object placing area can be sealed to form a closed cavity, and when the baffle plate moves to the second position, the object placing area can be opened to take out the articles. The gap between the object placing area and the baffle plate in this prior art where a facial mask can be inserted is small, resulting in inconvenient access to the facial mask and affecting the use experience; moreover, when the baffle plate is rotated open, it is easy to scrape against the surface of the door body, affecting the appearance of the door body. Summary of the Utility Model

[0004] In order to overcome the above-mentioned drawbacks of the prior art, the utility model provides a facial mask heating assembly, a door body and a refrigerator, which are convenient for accessing facial masks, improve the heating efficiency, and prevent scratching of the door body.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a facial mask heating assembly, which includes a receiving cavity and an outer cover arranged on the outer side of the door body. A first heating surface is arranged on the inner side of the receiving cavity. The outer cover is rotatably connected to the outside of the receiving cavity through a spiral rising structure, and the outer cover is configured to close the receiving cavity when closed; the spiral rising structure includes a spiral rising shaft body arranged on the outer cover and a double spiral rising step body arranged on the receiving cavity. Two spiral rising slide rail grooves corresponding to the double spiral rising step body are arranged at the front end of the spiral rising shaft body. A through hole for the spiral rising shaft body to pass through is arranged at the center of the double spiral rising step body, and the spiral rising shaft body is installed in the through hole; when the outer cover is rotated open, the two slide rail grooves on the spiral rising shaft body are driven to rotate and rise along the double spiral rising step body, so that the outer cover moves away from the receiving cavity while being rotated open.

[0006] A facial mask heating component provided by this technical solution has an outer cover that can move away from the accommodating cavity while being opened laterally and rotated upward in a spiral structure, thereby creating a gap with the door body, providing a larger operating space and facilitating the access and storage of facial masks. At the same time, since there is a gap between the outer cover and the door body after the outer cover is rotated open, it can prevent the inner surface of the outer cover from rubbing against the door body and protect the appearance of the door body. In addition, when the outer cover is closed, it makes a rotational downward pressing movement, which can press the facial mask in the accommodating cavity, enabling the facial mask to fully contact the heating surface and improving the heating efficiency.

[0007] In a preferred technical solution, two rotation-opening limiting parts protrude from one end of the double-spiral upward step body on the back of the accommodating cavity. The two rotation-opening limiting parts are respectively located at the ends of the upward slope and the downward slope of the double-spiral upward step body. Two opposite buckles protrude from the circumferential surface at the rear end of the spiral upward shaft body, and the chamfers of the two buckles are respectively arranged on the upward slope and the downward slope and can slide.

[0008] In this technology, the double-spiral upward step body is equipped with a limiting structure, enabling the outer cover to rotate to the optimal angle and stop, only opening a fixed angle. This is convenient for users to place and take facial masks, and also has a certain fixing effect, preventing the outer cover from opening and closing at too large an angle and causing the facial mask to fall due to lack of fixation. At the same time, through the buckle structure of the outer cover, the connection between the outer cover and the accommodating cavity is more stable, allowing for rotational movement without falling off.

[0009] In a preferred technical solution, among the two buckles, the chamfer angle of the buckle arranged on the upward slope is greater than the chamfer angle of the buckle arranged on the downward slope. In this technology, the chamfer angles of the two side buckles change differently. The chamfer angle of the buckle close to the upward slope is large, facilitating cooperation with the slope of the inclined plane and making the rotation smoother and more stable. The chamfer angle of the other buckle is small, facilitating rotation without jamming.

[0010] In a preferred technical solution, a second heating surface is provided on the inner side of the outer cover, and the second heating surface corresponds to the position of the first heating surface. This technology can heat the facial mask simultaneously from both sides of the accommodating cavity and the outer cover, improving the heating speed and efficiency.

[0011] In a preferred technical solution, a reset limiting groove is also provided on the accommodating cavity, and a reset limiting protrusion corresponding to the reset limiting groove is provided on the inner side of the outer cover, which can reset the outer cover to a fixed angle and prevent the second heating surface from contacting the door body part near the accommodating cavity, causing damage to the door body.

[0012] In a preferred technical solution, the reset limiting groove is an inverted triangular groove, and the reset limiting protrusion is an inverted triangular protrusion. This technology adopts an inverted triangular concave-convex matching structure, which is convenient for cooperation and has stable positioning, preventing deviation.

[0013] In a preferred technical solution, the first heating surface includes a first heat insulation plate, a first heating element, and a first heating plate sequentially arranged from the inside of the accommodation cavity to the outside; the second heating surface includes a second heating plate, a second heating element, and a second heat insulation plate sequentially arranged from the inside of the outer cover to the outside. This technology uses indirect heating by the heating plate, which can avoid overheating. The first heat insulation plate is used to reduce the impact of heating on the internal heat preservation of the beauty refrigerator and the cosmetic storage cabinet, and the second heat insulation plate is used to prevent the outer surface of the outer cover from overheating.

[0014] In a preferred technical solution, a first sensor is provided inside the accommodation cavity, and a second sensor is provided on the side of the outer cover facing the accommodation cavity; when the outer cover is closed on the accommodation cavity, the positions of the first sensor and the second sensor correspond. Through the mutual cooperation of the first sensor and the second sensor with corresponding positions, this technology can sense whether there are items placed in the accommodation cavity, facilitating an understanding of the items placed in the accommodation cavity.

[0015] A door body includes a mask heating assembly in any of the above technical solutions.

[0016] The door body in this technology adopts the above mask heating assembly, which is convenient for taking and placing masks, has a better heating effect, and can avoid scratching with the outer cover of the mask heating assembly, protecting the appearance.

[0017] A refrigerator includes a door body in any of the above technical solutions.

[0018] The refrigerator in this technology adopts the above door body. While providing the mask heating function, it is convenient for taking and placing masks, has a better heating effect, and can avoid scratching between the outer cover of the mask heating assembly and the door body, protecting the appearance.

[0019] From the above technical solutions, it can be seen that compared with the prior art, the beneficial effects of the present utility model are as follows: A mask heating assembly provided by the present utility model realizes the connection between the outer cover and the accommodation cavity of the door body through a spiral rising structure. The outer cover can be rotated open to the side. While rotating open, the outer cover moves forward, and the gap between the outer cover and the door body becomes larger, providing a larger operating space, and it is more convenient to place and take out masks; at the same time, since the outer cover rises when it is rotated open, the outer cover will not scratch the door body when it is rotated open, and will not affect the appearance of the door body; rotating the outer cover to press the mask makes the mask fit more closely to the heating surface, and the heating effect is better. A door body adopts the above mask heating assembly, which is convenient for taking and placing masks, has a better heating effect, and can avoid scratching with the outer cover of the mask heating assembly, protecting the appearance. A refrigerator adopts the above door body. While providing the mask heating function, it is convenient for taking and placing masks, has a better heating effect, and can avoid scratching between the outer cover of the mask heating assembly and the door body, protecting the appearance.

[0038] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model 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 cannot be construed as a limitation to the present utility model. In addition, in the description of the present utility model, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0039] Refer to Figures 1-14 Describe a facial - mask heating assembly, a door body and a refrigerator according to an embodiment of the present utility model.

[0040] In one embodiment, as Figures 1-14 shown, a facial - mask heating assembly includes an accommodation cavity 1 and an outer cover 2 provided on the outer side of the door body 100. A first heating surface 11 is provided on the inner side of the accommodation cavity 1. The outer cover 2 is rotatably connected to the outside of the accommodation cavity 1 through a helical - upward structure, and the outer cover 2 is configured to close the accommodation cavity 1 when closed.

[0041] The helical - upward structure includes a helical - upward - rising shaft body 22 provided on the outer cover 2 and a double - helical upward - stepped body 12 provided on the accommodation cavity 1. At the front end of the helical - upward - rising shaft body 22, there are two helical - upward slide - rail grooves 221 corresponding to and cooperating with the double - helical upward - stepped body 12. A through - hole for the helical - upward - rising shaft body 22 to pass through is provided at the axis of the double - helical upward - stepped body 12, and the helical - upward - rising shaft body 22 is installed in the through - hole.

[0042] When the outer cover 2 is unscrewed, the two slide rail grooves 221 on the spiral ascending shaft body 22 are driven to rotate and ascend along the double spiral ascending step body 12, so that the outer cover 2 moves away from the accommodating chamber 1 while being unscrewed.

[0043] Among them, the central axis of the spiral rising shaft body 22 is a circular axis, and the outer cover 2 is connected to the door body 100 provided with the accommodating cavity 1 through the circular axis, which can realize coaxial rotation movement; the double spiral rising step body 12 is arranged around the spiral rising shaft body 22 to form a spiral rising bottom track; the bottom surface of the two spiral rising slide rail grooves 221 is composed of a gradual curved surface matching the double spiral rising step body 12, and the two side walls are composed of the inner walls of a pair of concentric circular convex parts on both sides of the gradual curved surface. The two slide rail grooves 221 cooperate with the double spiral rising step body 12, so that the outer cover 2 is rotated to the side and the height is increased at the same time.

[0044] The accommodating cavity 1 of the facial mask heating assembly and the outer cover 2 cooperate with each other to use a spiral ascending structure, so that the spiral ascending movement and the swirling downward pressing movement of the outer cover 2 can be realized.

[0045] The outer cover 2 spirally moves upward: that is, when the outer cover 2 is unscrewed, the outer cover 2 moves upward from the closed state through the spiral structure as a whole, and moves forward while opening sideways. Since a certain distance is left between the outer cover 2 and the accommodating cavity 1 after unscrewing, more space can be left for placing and taking out the mask.

[0046] The outer cover 2 performs a rotary downward pressing movement: that is, during the closing process of the outer cover 2, the outer cover 2 performs a reverse rotation and reset operation from the open state through the spiral ascending structure, so that the outer cover 2 performs a rotary downward pressing movement, which can press the mask in the accommodating cavity 1 that has bulged on the surface due to placement and other factors, so that the mask is in full contact with the heating surface, which is beneficial to improving the heating efficiency.

[0047] In the above embodiment, the outer cover 2 and the accommodating cavity 1 are fixed by mechanical snap fastening, which is easy to install and does not require the tedious steps of screw installation. It also avoids deformation of the profile caused by screw fixing, which may hinder the movement of the components and affect the normal use of the components.

[0048] The mask heating assembly provided in this embodiment can be unscrewed to be raised and rotated to be compressed. The unscrewing and rotating operations are simple and convenient, and will not scratch the door body. It has the advantages of convenient access and protection of the appearance of the door body, and can provide a better user experience. It is suitable for products that require heated masks, such as beauty refrigerators, cosmetics cabinets, etc.

[0049] In this embodiment, two unlocking limiting parts 121 protrude from one end of the double-helical rising stepped body 12 on the back surface of the accommodating cavity 1. The two unlocking limiting parts 121 are respectively located at the ends of the rising slope surface and the falling slope surface of the double-helical rising stepped body 12; two opposite buckles 222 protrude from the circumferential surface at the rear end of the helically rising shaft body 22, and the chamfers of the two buckles 222 are respectively arranged on the rising slope surface and the falling slope surface and can slide and move.

[0050] Among them, the rear end of the helically rising shaft body 22 passes through the through hole and is located at the back of the accommodating cavity 1. During specific implementation, the two unlocking limiting parts 121 enable the outer cover 2 to be opened only at a fixed angle. On the basis of ensuring convenient access to the facial mask, it is avoided that the opening and closing angle of the outer cover 2 is too large, and the facial mask drops due to lack of fixation; at the same time, the part of the double-helical rising stepped body 12 on the back surface of the accommodating cavity 1 contacts the buckle 222 of the outer cover 2. When the outer cover 2 makes a rotational rising movement, the buckle 222 moves synchronously and is always clamped on the stepped body to maintain a stable movement, and it can be avoided that the outer cover 2 shakes and falls off significantly.

[0051] In this embodiment, among the two buckles 222, the chamfer angle of the buckle 222 arranged on the rising slope surface is larger than the chamfer angle of the buckle 222 arranged on the falling slope surface. The chamfer angles of the two side buckles 222 change differently. The chamfer angle of the buckle 222 close to the rising slope surface is large, which is convenient for matching with the slope of the inclined surface and the rotation is smoother and more stable. The chamfer angle of the other side buckle 222 is small, which is convenient for turning back without jamming.

[0052] In this embodiment, a second heating surface 21 is provided on the inner side of the outer cover 2. The second heating surface 21 corresponds to the position of the first heating surface 11, and the facial mask can be heated simultaneously on both sides, and the heating efficiency is higher.

[0053] In this embodiment, a reset limiting groove 13 is further provided on the accommodating cavity 1, and a reset limiting protrusion 23 corresponding to the reset limiting groove 13 is provided on the inner side of the outer cover 2. During specific implementation, the reset limiting protrusion 23 on the inner side of the outer cover 2 cooperates with the reset limiting groove 13 on the accommodating cavity 1, so that the outer cover 2 is reset to a fixed angle, which can ensure that when the outer cover 2 is reset, the second heating surface 21 on the inner side of the outer cover 2 returns to a fixed position and is in full contact with the facial mask, and it is avoided that the heating surface contacts other positions of the door body, causing damage to the door body and resulting in potential safety hazards.

[0054] In this embodiment, the reset limiting groove 13 is an inverted triangular groove, and the reset limiting protrusion 23 is an inverted triangular protrusion, with stable positioning and can prevent deviation.

[0055] In this embodiment, the first heating surface 11 includes a first heat insulation plate, a first heating element, and a first heating plate sequentially arranged from the inside of the accommodating cavity 1 to the outside; the second heating surface 21 includes a second heating plate, a second heating element, and a second heat insulation plate sequentially arranged from the inside of the outer cover 2 to the outside. In specific implementation, when the facial mask is placed in the accommodating cavity 1, it will be attached to the heating plates on both sides, and the heat generated by the heating element is conducted to the facial mask through the heating plate to achieve heating.

[0056] In this embodiment, a first sensor is provided inside the accommodating cavity 1, and a second sensor is provided on the side of the outer cover 2 facing the accommodating cavity 1; when the outer cover 2 is closed on the accommodating cavity 1, the positions of the first sensor and the second sensor correspond to each other. In this embodiment, the first sensor and the second sensor can cooperate with each other to sense whether an item such as a facial mask is placed in the accommodating cavity 1. Among them, one of the first sensor and the second sensor is a signal sending device, and the other is a signal receiving device. In specific implementation, the first sensor and the second sensor can be a pair of infrared sensors.

[0057] In another embodiment, the present utility model provides a door body 100, which includes the facial mask heating assembly in any of the above embodiments, facilitating the taking and placing of the facial mask, having a better heating effect, and being able to avoid scratching of the door body, which helps to protect the appearance of the door body. The above door body 100 can be the door body of products such as a beauty refrigerator, a cosmetic cabinet, etc.

[0058] In still another embodiment, the present utility model provides a refrigerator, which includes the door body 100 in the above embodiment. The refrigerator has the function of heating the facial mask, is convenient for taking and placing the facial mask, has a better heating effect, and can also avoid scratching of the door body. The above refrigerator can be products such as a beauty refrigerator, a cosmetic cabinet, etc.
