[0027] A towel heater is a small household appliance whose main function is to heat and keep towels warm so that they can provide a warm and comfortable experience when used.
[0028] Existing towel heating devices, in order to ensure that the towel is heated and dried evenly, not only have heating elements at the bottom but also on the inner wall of the device. Users reach into the tub to retrieve the heated towel, but there is a risk of accidentally touching the inner wall of the tub and getting burned during this process.
[0029] This utility model proposes a heating device 100, which aims to prevent users from being burned when they take out heated items and touch the inner wall of the bucket.
[0030] Please see Figures 1 to 4 In one embodiment of the present invention, the heating device 100 includes a barrel 1, a heating mechanism 2 and a lifting mechanism 3. The barrel 1 has an open receiving cavity 11; the heating mechanism 2 is disposed in the receiving cavity 11; the lifting mechanism 3 is movably disposed in the receiving cavity 11. The lifting mechanism 3 is used to place the heated item and can be lifted up and down to remove the heated item.
[0031] In this embodiment, the barrel 1 can be made of metal, such as stainless steel, or of rigid plastic. In a preferred embodiment, the barrel 1 can be made of double-layered material, with insulation material inside to reduce heat loss through the barrel 1. The heating mechanism 2 is located inside the receiving cavity 11 of the barrel 1. The heating mechanism 2 can be a PTC heating element, which consists of a PTC ceramic heating element and an aluminum tube, and has the advantages of low thermal resistance and high heat exchange efficiency. It can also be an electric heating tube or other heating device, without further limitation. In a preferred embodiment, the heating mechanism 2 also includes a fan, which is located at the bottom of the heating element to carry away the heat generated by the heating element through airflow, thereby improving heating efficiency. The lifting mechanism 3 can be a manual lifting mechanism 3 or an electric lifting mechanism 3. It can be implemented through a sliding connection between a guide rail and a tray 33 slidably connected to the guide rail. The tray 33 can be manually or electrically driven to slide relative to the guide rail, so that the heated item on the tray 33 is exposed outside the barrel 1, allowing the user to directly take the heated item without touching the barrel wall and getting burned. Understandably, other structures, such as pop-out mechanisms, can also be used to lift the heated items outside the bucket 1, so that users do not have to reach into the bucket to retrieve them, thus preventing burns from touching the bucket wall.
[0032] The heating device 100 proposed in this utility model includes a barrel 1, a heating mechanism 2, and a lifting mechanism 3. The barrel 1 has an open receiving cavity 11. The heating mechanism 2 and the lifting mechanism 3 are both located in the receiving cavity 11. The lifting mechanism 3 is located above the heating mechanism 2 and can move along the axial direction of the barrel 1. The lifting mechanism 3 is used to place the heated item. Driving the lifting mechanism 3 can lift at least part of the heated item to the outside of the barrel 1, so that the user can directly take the heated item without having to reach into the barrel to take it, reducing the safety hazard of being burned by touching the inner wall.
[0033] In one embodiment of the present invention, the heating device 100 includes a guide post 31, which is fixedly disposed in the receiving cavity 11. The lifting mechanism 3 is sleeved on the guide post 31 and can move along the guide post 31 and can be suspended relative to the guide post 31.
[0034] In this embodiment, the heating device 100 also includes a guide post 31 fixedly disposed in the receiving cavity 11. The lifting mechanism 3 can slide along the extension direction of the guide post 31. The cooperation between the lifting mechanism 3 and the guide post 31 can make the movement of the lifting mechanism 3 more stable and prevent the lifting mechanism 3 from tilting during the movement. The lifting mechanism 3 can be suspended relative to the guide post 31 so that the user can pick up the heated item on the lifting mechanism 3 without having to hold the lifting mechanism 3 with the other hand when picking up the heated item.
[0035] In one embodiment of the present invention, the lifting mechanism 3 includes a sleeve 32 and a tray 33. The sleeve 32 is sleeved on the guide post 31 and can move along the guide post 31 and can be suspended relative to the guide post 31. The tray 33 is connected to the sleeve 32 and is used to support the heated item.
[0036] In this embodiment, the lifting mechanism 3 includes a sleeve 32 fitted onto the guide post 31 and a tray 33 connected to one end of the sleeve 32. The sleeve 32 can slide along the extension direction of the guide post 31. The tray 33 is used to support items to be heated, such as towels. The sleeve 32 can be manually or electrically driven to make the tray 33 slide along the extension direction of the guide post 31. The heated items supported on the tray 33 are partially exposed outside the bucket body 1, so the user does not need to reach into the bucket to get them, thus preventing burns from touching the bucket wall. The tray 33 is connected to the end of the sleeve 32 facing the bottom of the guide post 31, making the space above the tray 33 larger, allowing for the placement of more heated items.
[0037] In one embodiment of the present invention, the guide post 31 has a heat-conducting inner cavity 311, the side wall of the guide post 31 has a first opening 312, the side wall of the sleeve 32 has a second opening 321, the second opening 321 communicates with the heat-conducting inner cavity 311, and when the sleeve 32 is not lifted, the first opening 312 communicates with the second opening 321.
[0038] In this embodiment, a heat-conducting inner cavity 311 communicating with the heating chamber 111 is provided inside the guide post 31, and a first opening 312 and a second opening 321 are respectively provided on the side wall of the guide post 31 and the side wall of the sleeve 32. When the sleeve 32 is in the initial state, that is, when the sleeve 32 is completely sleeved on the guide post 31, the first opening 312 and the second opening 321 are aligned, so that the hot air in the heating chamber 111 can directly enter the storage cavity 112 through the heat-conducting inner cavity 311, the first opening 312 and the second opening 321, thereby improving the heat transfer efficiency and thus improving the heating effect.
[0039] In one embodiment of this utility model, the tray 33 has a plurality of ventilation holes 323.
[0040] In this embodiment, the tray 33 has multiple ventilation holes 323, which connect the top and bottom of the tray 33. This allows heat to be transferred to the heated item not only through the heat conduction effect of the tray 33, but also through heat convection through the ventilation holes 323, thereby improving the heat transfer efficiency and thus enhancing the heating effect.
[0041] In one embodiment of the present invention, the heating device 100 further includes a base 35, which is disposed in the receiving cavity 11. The guide post 31 is connected to the base 35, and the heat-conducting inner cavity 311 is open on the side near the base 35.
[0042] In this embodiment, the heating device 100 further includes a base 35, which divides the receiving cavity 11 of the barrel 1 into a heating cavity 111 and a storage cavity 112. This divides the receiving cavity 11 into different functional areas, facilitating future maintenance or component replacement, and prevents the two cavities from interfering with each other, such as causing the towel to burn due to excessively high temperature in the storage cavity 112. A guide post 31 is disposed on the surface of the base 35, serving a guiding function. Connected to the barrel 1 via the base 35, it is positioned within the storage cavity 112. A sleeve 32 and a tray 33 are fitted onto the guide post 31 and can move along the extension direction of the guide post 31 within the storage cavity 112, thus exposing the heated item to the barrel 1 for easy access by the user. The heat-conducting inner cavity 311 of the guide post 31 is open on the side near the base 35, allowing the heat-conducting inner cavity 311 to communicate with the base 35.
[0043] In one embodiment of the present invention, the base 35 includes a main body and a support platform disposed on the main body, the tray 33 abuts against the support platform, the main body of the base 35 and the tray 33 are spaced apart, and the support platform is provided with ventilation holes.
[0044] In this embodiment, the base 35 includes a main body and a support platform disposed on the main body. The support platform has a vent hole that communicates with the vent hole 323 on the tray 33, so that the heating chamber 111 and the storage chamber 112 are connected. This allows heat to be transferred to the storage chamber 112 not only through the heat conduction effect of the support platform and the tray 33, but also through heat convection through the vent hole 323, thereby improving the heat transfer efficiency and thus improving the heating effect.
[0045] In one embodiment of the present invention, one of the inner wall of the sleeve 32 and the outer wall of the guide post 31 is provided with a limiting part 313 and the other is provided with a limiting groove 322. The limiting part 313 can be engaged with the limiting groove 322 so that the lifting mechanism 3 is suspended on the guide post 31.
[0046] In this embodiment, the cooperation of the limiting part 313 and the limiting groove 322 enables the sleeve 32 to hover relative to the guide post 31. After releasing the hand, the sleeve 32 will not slide downwards relative to the guide post 31, allowing the user to free one hand and use both hands to pick up the heated item. The limiting part 313 can be a ball-shaped structure. When not subjected to external force, the ball-shaped structure is in an ejected state and can be locked within the limiting groove 322, preventing the sleeve 32 from sliding downwards. When the sleeve 32 is driven, the vertical force can compress the ball-shaped structure, causing it to retract without affecting the sliding of the sleeve 32. It is understood that in other embodiments, the limiting part 313 can also be a buckle structure with beveled surfaces on both sides. The buckle engages with the limiting groove 322 to prevent the sleeve 32 from sliding downwards. When the sleeve 32 is driven, the beveled surfaces on both sides act as a guide, causing the buckle to disengage from the limiting groove 322 without affecting the sliding of the sleeve 32. Preferably, the limiting groove 322 is provided on the sleeve 32, and the sleeve 32 can use the elasticity of its own material to achieve the engagement and disengagement of the limiting groove 322 and the limiting part 313. There are multiple limiting parts 313 and limiting grooves 322, which can achieve the effect of multi-stage suspension of the sleeve 32 relative to the guide post 31.
[0047] In one embodiment of the present invention, the lifting mechanism 3 is provided with a handle 34 so as to lift the lifting mechanism 3 by means of the handle 34.
[0048] In this embodiment, a handle 34 is provided at one end of the lifting mechanism 3 near the opening of the receiving cavity 11. The direction of the handle 34 can be perpendicular to or the same as the extension direction of the lifting mechanism 3, depending on the actual use of the product. The handle 34 can save effort. Driving the handle 34 will slide the lifting mechanism 3 relative to the guide column 31, thereby exposing the heated item supported on the tray 33 outside the barrel 1. The user does not need to reach into the barrel to retrieve it, thus preventing burns from touching the barrel wall. The handle 34 is made of heat-insulating material, such as silicone, rubber, or high-temperature resistant plastic, to prevent heat from being transferred from the sleeve 32 to the handle 34, thereby preventing burns from excessive temperature when the user manually drives the handle 34.
[0049] In one embodiment of the present invention, the heating device 100 further includes a cover 4, which covers the opening connected to the barrel 1. The heating mechanism 2 includes a fan and a heating element that heats the air blown out by the fan. The barrel 1 includes an inner barrel and an outer barrel. The heating mechanism 2 is located at the bottom of the outer barrel, and the inner barrel is located inside the outer barrel. The lifting mechanism 3 is movably located inside the inner barrel. The inner barrel has an air hole that communicates with the outer barrel.
[0050] In this embodiment, the heating device 100 further includes a lid 4 connected to the barrel 1. The lid 4 can reduce heat loss from the opening of the barrel 1, thereby improving the overall heating and heat preservation effects of the heating device 100. In a preferred embodiment, the lid 4 has an internal structure filled with heat-insulating material and is rotatably connected to the edge of the opening of the barrel 1, and can achieve stepless hovering to prevent the lid 4 from rotating and affecting the retrieval of items. The heating mechanism 2 includes a fan and a heating element that heats the air blown by the fan. Part of the hot airflow enters the inner barrel through the air hole to directly heat the items inside the inner barrel, while the other part enters the space between the inner barrel and the outer barrel to indirectly heat the items inside the inner barrel.
[0051] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
