Description

Technical Field

[0001] The invention belongs to the technical field of heating equipment production, and in particular relates to a multifunctional heating table. Background Art

[0002] As a household appliance that combines heating and tabletop functions, electric heating tables are widely used in various settings during cold weather, including living rooms, bedrooms, and offices. Whether it's a place for friends and family to chat, children to study, or adults to work, electric heating tables, with their combination of practicality and comfort, can become a core piece of furniture in any space. They typically consist of a tabletop, support columns, and a base. The tabletop, often made of heat-resistant, easy-to-clean materials, is used to place items such as cups, books, and office supplies, or for direct use. The support columns not only connect the tabletop and base and provide structural support, but some models also incorporate internal circuitry to power the heating function. The base provides a shield and protection for the bottom of the table, preventing dust and debris from entering and affecting the circuit components. Some electric heating tables also have integrated heating elements in the base, radiating heat downward to warm the user's legs and feet, further enhancing the warmth.

[0003] In existing electric heating tables, the base is typically rigidly connected to the surrounding support columns through welding or bolting. This design primarily takes into account the ease of movement and heat dissipation requirements of the electric heating table. From a mobility perspective, if the base is in direct contact with the ground, significant friction will be generated between the base and the ground when the electric heating table is moved. This, combined with the weight of the table itself, makes the process very laborious. This friction can also cause wear and tear on the floor, especially in homes with wooden floors or carpets. From a heat dissipation perspective, the base of the heating table generates a certain amount of heat during operation. If it is in direct contact with the ground, this heat cannot be dissipated quickly, causing the base to continue to heat up. This not only reduces heating efficiency but can also accelerate the aging of internal circuits, potentially leading to safety hazards such as short circuits. Therefore, existing electric heating tables often leave a gap of approximately 2-5 cm between the base and the ground to balance ease of movement and heat dissipation requirements.

[0004] However, this seemingly necessary reserved gap has brought new problems. Due to the existence of the gap, dust, food crumbs, pet hair, hair and other debris in daily life can easily enter and accumulate under the bottom plate of the table during sweeping, mopping or daily activities, forming a sanitary dead corner that is difficult to clean. And because the gap space is narrow, the brush heads of conventional cleaning tools such as brooms and mops are difficult to penetrate into it. Even if the user wants to clean it, they can only do it by bending the tool or leaning over to pick it up with their hands, or moving the weighed electric heating table away, which is not only inconvenient to operate, but also difficult to completely remove the accumulated stains. Over time, the stains under the bottom plate of the table will accumulate more and more, which not only affects the overall appearance and cleanliness of the electric heating table, but may also become a breeding ground for mites and bacteria, posing a potential threat to the health of the residents and causing great trouble to the user's daily cleaning and maintenance. Summary of the Invention

[0005] The present invention aims to provide a multifunctional heating table, which is mainly used to solve the technical problem in the prior art that a gap is maintained between the bottom plate of the table and the ground, which makes it easy for dirt and grime to accumulate in the gap and is inconvenient to clean.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: A multifunctional heating table comprises a table bottom plate, wherein support columns are arranged at four corners of the table bottom plate, and a table top plate is fixed to the top surfaces of the four support columns; the table bottom plate and the support columns can slide relative to each other.

[0007] The beneficial effects of the present invention are as follows: In this solution, the table bottom plate and the support column can slide relative to each other. During use, when it is necessary to clean under the table bottom plate, it is only necessary to lift the table bottom plate to clean under the table bottom plate, which is more convenient to use.

[0008] Preferably, the table bottom plate includes a sliding frame slidably connected to the support column, and a main bottom plate is fixed to the sliding frame. A receiving slot is defined in the middle of the main bottom plate, and the two ends of the receiving slot are slidably connected to the auxiliary bottom plates. In this solution, when the table bottom plate is moved up to the middle of the support column, the user can place their feet under the table bottom plate and then push the auxiliary bottom plates into the receiving slots, which is equivalent to the concave sides of the main bottom plate for the user to place their knees, thereby improving the comfort of using the heating table in different conditions.

[0009] Preferably, the sliding frame includes a sliding assembly slidably connected to the support column, and a driving assembly is commonly installed at the bottom of the four sliding assemblies; A first slide groove is provided on the support column, the first slide groove opens vertically downward, a fixed cylinder with an opening direction vertically downward is fixed in the center of the first slide groove, the inner wall of the fixed cylinder is provided with a thread, the sliding assembly includes a slider that can slide in the first slide groove, the middle of the slider is provided with a sliding hole for accommodating the fixed cylinder and over-matching with the fixed cylinder, and a screw is connected to the internal thread of the fixed cylinder; The driving device includes a housing detachably connected to the bottom of the slider, the lower end of the screw penetrates into the interior of the housing and is rotatably connected to the housing, and a first bevel gear is coaxially fixed to the screw inside the housing; The driving device also includes an active driving rod and two driven driving rods, wherein the second bevel gear meshing with the first bevel gear is symmetrically and coaxially fixed at both ends of the driven driving rod, and the third bevel gear is coaxially fixed to the middle of the driven driving rod. The fourth bevel gear meshing with the third bevel gear is coaxially fixed to both ends of the active driving rod, and the fifth bevel gear is coaxially fixed to the middle of the active driving rod. A driving motor is fixed to the side wall of the housing, and a sixth bevel gear meshing with the second bevel gear is fixed to the output shaft of the driving motor.

[0010] In this solution, when the motor rotates, it transmits the power through the sixth, fifth, fourth, third, second and first bevel gears, thereby driving the screw to rotate, and then driving the slider to slide in the first slide groove, and finally realizing the sliding frame, that is, the table bottom plate slides up and down relative to the support column.

[0011] Preferably, the table base is detachably connected to a food warming stand. In this solution, when the table base is raised, the food warming stand can be installed on it, and food can be temporarily placed on the warming stand. The air heated by the heating tube can keep the food warm. Furthermore, because the height of the table base is adjustable, the distance between the food warming stand and the table top can be adjusted according to the height of the tableware.

[0012] Preferably, a barrier cloth is detachably connected around the desktop panel, and the barrier cloth is a one-piece structure with a plurality of slits in the middle and lower part of the barrier cloth. In this solution, the slits in the barrier cloth are provided so that when the user extends his hands and feet under the desktop panel, the barrier cloth can better cover the user's body and achieve a better heat preservation effect.

[0013] Preferably, the retaining cloth is detachably connected to the desktop panel via Velcro, and the Velcro includes a hook surface and a fleece surface; a hook surface is fixed on one side of the upper edge of the retaining cloth surface, and a fleece surface is fixed on the other side; a plurality of first fixing plates and a plurality of second fixing plates are equidistantly and cross-distributed on the side of the desktop panel; a side of the first fixing plate away from the desktop panel is set to the hook surface, and a side of the second fixing plate away from the desktop panel is set to the fleece surface.

[0014] Conventional heating tables require a cloth to lock heat under the tabletop, and users pass their hands and feet through the cloth and place them under the tabletop to keep warm. However, the tabletop area of ​​the heating table in this solution is adjustable, and ordinary cloths cannot adapt well to this tabletop. We have designed a customized cloth. When using it, you can use the front or back of the cloth to face the perimeter of the tabletop, and then directly stick the hook or fleece side of the Velcro to the first or second fixing piece, and then surround it in a circle. After connecting the ends, the excess part is directly covered and adhered to the surface of the cloth with Velcro. This structure of the cloth can adjust the enclosed area at any time according to the changes in the area of ​​the tabletop when in use, and there is no need to distinguish which side of the cloth is fixed to the tabletop, which is very convenient to use.

[0015] Preferably, the desktop panel includes a main panel with a sub-panel slidably connected below the main panel. In this solution, when the number of people warming increases, the sub-panel can be slid out to increase the desktop area and accommodate more people sitting around the desktop to share warmth.

[0016] Preferably, a second sliding groove for accommodating the auxiliary panel is provided in the middle of the main panel; A first limiting plate is fixed on the upper sides of both ends of the second chute, and a second limiting plate is fixed on the middle of the upper surface of the auxiliary panel. The second limiting plate is located inside the second chute and the upper end thereof is in sliding contact with the top of the second chute; The bottom of the auxiliary panel is in sliding contact with the bottom of the second chute; A third limiting plate is fixed to the end surface of one end of the auxiliary panel located outside the second sliding groove, which is used to prevent the auxiliary panel from being completely pushed into the second sliding groove.

[0017] In this solution, when the secondary panel is pulled out of the second slot, the second limiting plate contacts the first limiting plate, preventing further extension of the secondary panel. When the secondary panel is pushed into the second slot, the third limiting plate prevents further insertion. This solution, through the provision of three limiting plates, allows the secondary panel and the main panel to slide freely relative to each other.

[0018] Preferably, the second chute is provided with rubber damping strips on both sides, which are in contact with the side surfaces of the secondary panel. In this solution, when the secondary panel is pushed, the damping strips and the secondary panel generate a large friction force, so that the secondary panel will not be easily touched and moved after being pulled out or pushed in.

The terms "first," "second," and "third" are used solely for descriptive purposes and to distinguish technical features. They are not to be construed as indicating or implying relative importance, or as implicitly specifying the number or order of the technical features indicated.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified or limited, the terms "installed," "connected," "connected," and "set" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium, or they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances. The following describes an embodiment of the present invention based on its overall structure.

[0027] like Figure 1 As shown, a multifunctional heating table includes a table bottom plate, and support columns 21 are provided at the four corners of the table bottom plate, and a table top plate is fixed to the top surfaces of the four support columns 21; the table bottom plate and the support columns 21 can slide relative to each other. During use, when it is necessary to clean the bottom of the table bottom plate, it is only necessary to lift the table bottom plate to clean the bottom of the table bottom plate, which is more convenient to use.

[0028] A groove is provided in the support column 21, and a heating tube is provided in the groove. The side opening of the groove is covered with an isolation net with a curved surface. The isolation net and the groove together form a heating chamber. The heating tube continuously heats the gas in the heating chamber and then releases it outside the heating chamber to provide heating for the user.

[0029] like Figure 1-Figure 3 The table bottom plate includes a sliding frame slidably connected to the support column 21 (a guard plate 46 is provided at the bottom of the sliding frame, and the sliding frame can be repaired by removing the guard plate 46). A main bottom plate 41 is also fixed on the sliding frame. The main bottom plate 41 is I-shaped, and the two waists are concave for storing the auxiliary bottom plate 43. A receiving groove 42 is opened in the concave part of the middle part of the main bottom plate 41, and the two ends of the internal side of the receiving groove 42 are slidably connected to the auxiliary bottom plate 43; Figure 3 As shown, when the table bottom plate is moved up to the middle of the support column 21, the user can place their feet under the table bottom plate, and then push the auxiliary bottom plate 43 into the receiving groove 42, which is equivalent to the depressions on both sides of the main bottom plate 41 for the user to place his knees, thereby improving the comfort of using the heating table in different states. In order to achieve the limitation of the main bottom plate 41 and the auxiliary bottom plate 43, a first limiting block 431 is fixed to the end of the auxiliary bottom plate 43 located outside the receiving groove 42, and a second limiting block 44 is also provided at the edge of the depressions on both sides of the main bottom plate 41 to prevent the auxiliary bottom plate 43 from falling out. It should be noted that after the auxiliary bottom plate 43 is fully extended, at least 1 / 4 of its volume is still located in the receiving groove 42.

[0030] like Figure 7 、 Figure 8 As shown, in order to achieve the sliding of the sliding frame, the sliding frame is set to the following structure: the sliding frame includes a sliding component slidably connected to the support column 21, and a driving component is commonly installed at the bottom of the four sliding components.

[0031] A first slide groove 22 is provided on the support column 21, and the lower edge of the first slide groove 22 is bent. The first slide groove 22 opens vertically downward, and a fixed cylinder 23 with an opening direction vertically downward is fixed to the center of the first slide groove 22. The inner wall of the fixed cylinder 23 is provided with a thread. The sliding assembly includes a slider 31 that can slide in the first slide groove 22, and the cross-sectional shape of the slider 31 is consistent with the shape of the lower edge of the first slide groove 22, and a limiting ring is fixed on the upper edge of the slider 31. The lower surface of the limiting ring can interfere with the inward bending part of the lower surface of the first slide groove 22 to prevent the slider 31 from being directly pulled out of the first slide groove 22 (because this structure belongs to a conventional sliding limit structure and is not closely related to the core innovation of this solution, it is not described in drawings here, only in text).

[0032] like Figure 6 、 Figure 6 、 Figure 8As shown, a sliding hole is opened in the middle of the slider 31 for accommodating the fixed cylinder 23 and overfitting with the fixed cylinder 23. The internal thread of the fixed cylinder 23 is connected with a screw 32, and the screw 32 can move inside the fixed cylinder 23 when it rotates. like Figure 3 、 Figure 8 As shown, the driving device includes a housing 33 detachably connected to the bottom of the slider 31. The lower end of the screw 32 penetrates into the interior of the housing 33 and is rotatably connected to the housing 33 via a bearing. Therefore, when the screw 32 moves, the housing 33 can also be driven to move up and down. like Figure 7 As shown, the screw rod 32 is coaxially fixed with a first bevel gear 321 inside the housing 33; the driving device also includes an active driving rod 35 and two driven driving rods 34, and the two ends of the driven driving rod 34 are symmetrically and coaxially fixed with a second bevel gear 341 that meshes with the first bevel gear 321, and the middle part of the driven driving rod 34 is also coaxially fixed with a third bevel gear 342, and the two ends of the active driving rod 35 are coaxially fixed with a fourth bevel gear 351 that meshes with the third bevel gear 342, and the middle part of the active driving rod 35 is also coaxially fixed with a fifth bevel gear 352, and a driving motor 36 is fixed to the side wall of the housing 33, and the output shaft of the driving motor 36 is fixed with a sixth bevel gear 361 that meshes with the second bevel gear 341.

[0033] When in use, when the motor rotates, it transmits power through the sixth, fifth, fourth, third, second and first bevel gears 321, thereby driving the screw 32 to rotate, and then driving the slider 31 to slide in the first slide groove 22, and finally realizing the sliding frame, that is, the table bottom plate slides up and down relative to the support column 21.

[0034] like Figure 1 As shown, the table base is detachably connected to a food warming stand 5. The stand 5 can be placed directly on the main base 41, or it can be screwed to the main base 41 as needed. Once the table base is raised, the stand 5 can be installed, and food can be temporarily placed on it. The air heated by the heating tubes keeps the food warm. Because the table base is height-adjustable, the distance between the stand 5 and the tabletop can be adjusted based on the height of the tableware.

[0035] At the same time, the support column 21 includes a main support column 21 and a secondary support column 21. A sliding cavity is provided in the main support column 21, and the secondary support column 21 can slide in the sliding cavity in a controllable state. This part is the height adjustment function of most electric heating tables, which belongs to the existing technology. The technical details are not repeated here. However, this function is combined with the table bottom plate lifting function in this solution to make the multifunctional heating table more flexible in operation. For example, when the table top plate can be adjusted in height, the table bottom plate is further raised to match the distance between it and the table top plate, which is used to place dishes for insulation or to form an adjustable height storage space for placing daily necessities such as paper towels, providing a more flexible usage solution for the heating table.

[0036] At the same time, the heat source in this solution is located on the four-sided support columns 21. When the table bottom plate is raised to a certain height, the user's feet can still step freely and comfortably on the bottom surface, and the heat released by the four-sided support columns 21 can still directly contact the human feet. Compared with some heating tables that set the heat source under the table top plate (if the heat source is set under the table top plate, the raising of the table bottom plate will block the heat transfer from above, resulting in insufficient heating for the user's feet), the heat source setting position of this solution is highly matched with the specific structure of this heating table. No matter what height the table bottom plate is raised or lowered, there is sufficient heat supply in the multi-layer space under the table top plate.

[0037] like Figure 9 、 Figure 10 、 Figure 11 As shown, the desktop panel includes a main panel 11, and a sub-panel 12 is slidably connected to the bottom of the main panel 11; when the number of people warming up increases, the sub-panel 12 can be slid out to increase the desktop area and accommodate more people sitting around the desktop to keep warm together.

[0038] A second chute for accommodating the sub-panel 12 is provided in the middle of the main panel 11; first limiting plates 111 are fixed to the upper sides of both ends of the second chute, and a second limiting plate 121 is fixed to the middle of the upper surface of the sub-panel 12. The second limiting plate 121 is located inside the second chute and its upper end is in sliding contact with the top of the second chute; the bottom of the sub-panel 12 is in sliding contact with the bottom of the second chute. This structure ensures that the sub-panel 12 is in stable contact with the second chute and will not shake under reasonable use pressure after unfolding; A third limiting plate 122 is fixed to the end surface of the auxiliary panel 12 located outside the second sliding groove, which is used to prevent the auxiliary panel 12 from being completely pushed into the second sliding groove.

[0039] When in use, the secondary panel 12 is pulled out of the second chute. When the second limiting plate 121 contacts the first limiting plate 111, the secondary panel 12 cannot be pulled out any further. When the secondary panel 12 is pushed into the second chute, the third limiting plate 122 limits the position, preventing the secondary panel 12 from being pushed into the second chute. This solution, through the provision of three limiting plates, allows the secondary panel 12 and the main panel 11 to achieve free relative sliding.

[0040] like Figure 1 As shown, damping strips 7 made of rubber are provided on both sides of the second slide groove. The damping strips 7 are in contact with the side surfaces of the sub-panel 12. When the sub-panel 12 is pushed, the damping strips 7 and the sub-panel 12 generate a large friction force, so that the sub-panel 12 will not be easily touched and moved after being pulled out or pushed in.

[0041] like Figure 12 、 Figure 13 As shown, a detachable barrier cloth 8 is attached around the tabletop (the barrier cloth 8 is not shown, but its structure is clear from the text description). The barrier cloth 8 is a one-piece structure with a plurality of slits in the middle and lower part of the barrier cloth 8. In this embodiment, the slits are provided to better cover the user's body when the user extends his or her hands and feet under the tabletop, thereby improving the heat preservation effect.

[0042] The retaining cloth 8 is detachably connected to the desktop panel via Velcro, which includes a hook surface and a fleece surface. A hook surface is fixed on one side of the upper edge of the retaining cloth 8, and a fleece surface is fixed on the other side. A plurality of first fixing pieces 61 and a plurality of second fixing pieces 62 are equidistantly and cross-distributed on the side of the desktop panel. The first fixing pieces 61 and the second fixing pieces 62 can be attached to the desktop panel by means of traceless adhesive and can be torn off when not needed. The first fixing piece 61 is provided with a hook surface on a side away from the desktop panel, and the second fixing piece 62 is provided with a fleece surface on a side away from the desktop panel.

[0043] Conventional heating tables require a barrier cloth 8 to lock heat under the tabletop. Users pass their hands and feet through the barrier cloth 8 and place them under the tabletop to keep warm. However, the tabletop area of ​​the heating table in this solution is adjustable, and ordinary barrier cloth 8 cannot adapt well to the tabletop. Now, a customized barrier cloth 8 is designed. When using it, you can use the front or back side of the barrier cloth 8 to face the periphery of the tabletop, and then directly stick the hook side or the fleece side of the Velcro to the first fixing piece 61 or the second fixing piece 62, and then surround it. After connecting the ends, the excess part is directly covered and adhered to the surface of the barrier cloth 8 with Velcro. The barrier cloth 8 with this structure can adjust the enclosed area at any time according to the change of the tabletop area when in use, and there is no need to distinguish which side of the barrier cloth 8 is fixed to the tabletop, which is very convenient to use. The foregoing descriptions of specific exemplary embodiments of the present invention are for the purpose of illustration and description. These descriptions are not intended to limit the invention to the precise form disclosed, and it is obvious that many changes and variations can be made based on the above teachings. Although an embodiment of the present invention has been shown and described, this specific embodiment is only an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described can be combined in an appropriate manner in any one or more embodiments or examples. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present invention and its practical application, so that those skilled in the art can make modifications, substitutions, variations and various different selections and changes to the embodiments as needed without departing from the principles and purpose of the present invention after reading this specification, but they are protected by patent law as long as they are within the scope of the claims of the present invention.
