Technical Field
[0001] The utility model relates to the technical field of household appliances, in particular to an energy-saving water-boiling liner and a water-boiling bottle having the same. Background Art
[0002] This section only provides background information related to the present application to help those skilled in the art understand the present application more thoroughly and accurately, and it is not necessarily prior art.
[0003] In order to effectively reduce the heat exchange between the water in the water boiling tank and the outside, maintain the water temperature, and reduce the energy consumption of the product, the existing water boiling tank usually adopts the following methods for heat insulation:
[0004] (1) The first method is to design the water boiling tank into a double-layer stainless steel structure and evacuate the interior. Although this method can achieve good thermal insulation, the processing technology is very complicated and the cost is high. (2) The second method is to set a heat insulation cover on the outside of the water boiling tank and fill the space between the two with foam material. Although this method can also achieve good thermal insulation, it is more troublesome to operate because it is necessary to open holes in the heat insulation cover to fill the foam material. At the same time, the foam material is prone to aging after a long period of use, resulting in poor thermal insulation effect. In addition, some foam materials will also produce pollutants, which are harmful to human health. (3) The third method is to cover the water boiling tank with thermal insulation cotton. Although this method is low-cost and simple to operate, the thermal insulation effect is poor.
[0005] Therefore, how to provide a water boiling tank structure with simple structure, convenient assembly, low cost and good heat insulation effect is a technical problem to be solved urgently by those skilled in the art. Utility Model Content

[0029] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0030] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the modules or components referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0032] Embodiment 1
[0033] See also Figure 1-4The utility model provides an energy-saving water-boiling inner pot, comprising an inner pot body 1 and a heat-insulating sleeve 2 sleeved on the outer periphery of the inner pot body 1. The heat-insulating sleeve 2 comprises a cylindrical body part 23, an upper closing part 24 arranged at the top of the body part 23 and contracted toward the center, and a lower closing part 25 arranged at the bottom of the body part 23 and contracted toward the center; the diameters of the upper closing part 24 and the lower closing part 25 are both smaller than the diameter of the body part 23; when the heat-insulating sleeve 2 is sleeved on the outer periphery of the inner pot body 1, the upper closing part 24 is sealed with the outer side wall of the upper end of the inner pot body 1, and the lower closing part 25 is sealed with the outer side wall of the lower end of the inner pot body 1 so that a sealed cavity for heat insulation and heat preservation is formed between the heat-insulating sleeve 2 and the inner pot body 1.
[0034] On the basis of the above structure, the upper closing portion 24 and the lower closing portion 25 of the insulation sleeve 2 are respectively sealed with the upper and lower outer side walls of the inner tank body 1, so that a closed cavity is formed between the insulation sleeve 2 and the inner tank body 1. The air in the cavity is used for insulation and heat preservation, which can effectively reduce the heat energy exchange between the water in the boiling water tank and the outside, thereby maintaining the temperature of the water in the inner tank and reducing the energy consumption of the product.
[0035] Among them, it is easy to think that when the heat insulation sleeve 2 is set close to the inner tank body 1, the heat of the inner tank body 1 is easily transferred to the heat insulation sleeve 2 and exchanges heat energy with the outside world because the heat insulation sleeve 2 is close to the inner tank body 1, thereby greatly reducing the heat insulation effect. Therefore, it is necessary to control the distance between the heat insulation sleeve 2 and the inner tank body 1; preferably, the maximum width of the sealed cavity in the horizontal direction is L, and L≥1mm.
[0036] Therefore, within this width range, it is possible to ensure that there is a certain amount of air in the sealed cavity, so that the air can be used for insulation and heat preservation, thereby improving the heat preservation effect of the water boiling tank.
[0037] In addition, in order to further improve the heat insulation effect of the heat insulation sleeve 2, the heat insulation sleeve 2 needs to be extended as much as possible in the vertical direction under the condition that the structure allows. Specifically, the highest position of the sealed cavity in the vertical direction needs to be higher than the highest liquid level in the liner body 1, so as to improve the heat insulation of the upper end of the liner body 1; preferably, a first height difference H1 is formed between the highest position of the sealed cavity and the highest liquid level in the liner body 1, and H1≥1mm is satisfied.
[0038] Similarly, the lowest position of the sealed cavity in the vertical direction needs to be lower than the lowest liquid level of the inner liner body 1, so as to improve the thermal insulation of the lower end of the inner liner body 1; preferably, a second height difference H2 is formed between the lowest position of the sealed cavity and the lowest liquid level in the inner liner body 1, and H2≥1mm.
[0039] Furthermore, since a heating component 3 is provided at the bottom of the inner tank body 1, in order to further improve the thermal insulation effect, the lowest position of the sealed cavity in the vertical direction can be lower than the lowest position of the heating component 3, so that the sealed cavity is used to insulate the heating component 3, thereby reducing the energy consumption of the heating component 3 and improving the thermal insulation performance of the product.
[0040] Of course, in order to further improve the thermal insulation effect of the thermal insulation sleeve 2, a layer of high-reflectivity thermal insulation film (such as PET composite film) can be bonded to the inner wall of the thermal insulation sleeve 2, or a layer of high-reflectivity thermal insulation coating (such as varnish, etc.) can be coated on the inner wall of the thermal insulation sleeve 2, so as to effectively block the heat radiation and thus improve the thermal insulation effect of the thermal insulation sleeve 2.
[0041] See also Figure 1-4 The liner body 1 comprises an liner body 11 and an liner bottom 12 arranged at the bottom opening of the liner body 11, and a heating component 13 is arranged at the bottom of the liner bottom 12. Specifically, the liner body 11 is cylindrical, and the liner bottom 12 is an inverted disc-shaped structure. The bottom edge of the liner bottom 12 is bent outward to form a flange 121. The liner body 11 is sleeved on the outer side of the liner bottom 12, and the bottom of the liner body 11 extends into the flange 121 and is connected and fixed by gluing.
[0042] Among them, the middle section of the inner liner body 11 is bulged to form a special-shaped structure that is wide in the middle and narrow at both ends. At this time, it is necessary to design the insulation sleeve 2 into a split structure to be split into two parts, a first insulation sleeve unit 21 and a second insulation sleeve unit 22. Then, the first insulation sleeve unit 21 and the second insulation sleeve unit 22 are spliced left and right to be mounted on the outer side of the inner liner body 11.
[0043] Specifically, a plurality of first mounting plates 211 are sequentially arranged at intervals from top to bottom on the edge of the first thermal insulation sleeve unit 21, and mounting holes 2111 are provided on the first mounting plates 211; a second mounting plate 221 is provided at a position corresponding to the first mounting plate 211 on the edge of the second thermal insulation sleeve unit 22, and a nut column 2211 is provided on the second mounting plate 221. Therefore, the first thermal insulation sleeve unit 21 and the second thermal insulation sleeve unit 22 can be connected and fixed by using bolts passing through the mounting holes 2111 and being threadedly fixed on the nut column 2211.
[0044] It can be understood that when the first insulation sleeve unit 21 and the second insulation sleeve unit 22 are spliced into the insulation sleeve 2, the diameter of the upper closing portion 24 of the insulation sleeve 2 is slightly smaller than the upper end diameter of the inner liner body 1, and the diameter of the lower closing portion 25 of the insulation sleeve 2 is slightly smaller than the lower end diameter of the inner liner body 1, so that the upper closing portion 24 can be interference fit with the upper end outer wall of the inner liner body 1 to achieve sealing, and the lower closing portion 25 can be interference fit with the lower end outer wall of the inner liner body 1 to achieve sealing.
[0045] It should be noted that the heat insulation sleeve 2 is made of plastic material, which has a certain elastic deformation, so as to facilitate the splicing of the first heat insulation sleeve unit 21 and the second heat insulation sleeve unit 22 to achieve sleeve installation outside the liner body 1. Preferably, the heat insulation sleeve 2 is made of PP material.
[0046] In addition, this embodiment also provides a water boiling bottle (not shown in the figure), including an outer shell and a water boiling liner arranged in the outer shell. Therefore, by arranging the water boiling liner in the water boiling bottle, the heat energy exchange between the water boiling liner and the outside can be effectively reduced, thereby maintaining the temperature of the water boiling liner and reducing the energy consumption of the product.
[0047] Embodiment 2
[0048] See also Figure 5 The difference between the water boiling liner in this embodiment and the first embodiment is that the structure of the liner body 11 is different. In this embodiment, the liner body 11 is a straight cylindrical structure; at this time, the heat insulation sleeve 2 can be designed as an integrated structure and ensure that the diameter of the upper closing part 24 and the lower closing part 25 of the heat insulation sleeve 2 are slightly larger than the diameter of the liner body 11; when assembly is required, the heat insulation sleeve 2 only needs to be set on the outer part of the liner body 1 from top to bottom, and then the upper closing part 24 of the heat insulation sleeve 2 and the upper end outer wall of the liner body 1 are sealed with glue, and the lower closing part 25 and the lower end outer wall of the liner body 1 are sealed with glue to achieve the connection and fixation of the heat insulation sleeve 2 and the liner body 1.
[0049] Of course, it should be noted that, in this embodiment, the heat insulation sleeve 2 can also be designed as a split structure (such as the method in the first embodiment), which is not limited here.
[0050] In summary, the utility model provides an energy-saving water-boiling liner and a water bottle having the same, wherein the upper closing portion 24 and the lower closing portion 25 of the heat-insulating sleeve 2 are respectively sealed with the upper and lower outer side walls of the liner body 1, so that a closed cavity is formed between the heat-insulating sleeve 2 and the liner body 1, and the air in the cavity is used for insulation and heat preservation, which can effectively reduce the heat energy exchange between the water-boiling liner and the outside, thereby maintaining the temperature of the water-boiling liner and reducing the energy consumption of the product.
[0051] It should be understood that the orientations or positional relationships indicated by the terms "top", "bottom", "inside", "outside", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the modules or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0052] In addition, in the description of the present utility model, "multiple" and "several" mean two or more than two, unless otherwise clearly and specifically defined.
[0053] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
