Description

Technical Field

[0001] The utility model relates to the technical field of water boilers, in particular to a non-convection hollow heat-insulating cavity. Background Art

[0002] A water boiler, also known as a water boiler, is a water boiling device that converts electrical energy into thermal energy.

[0003] Existing water boilers typically include a housing, a heating device, a heat preservation barrel, and a water outlet pipe. The heating device heats water until it boils, which is then temporarily stored in the heat preservation barrel before being directed to a cup via the water outlet pipe. However, existing water boilers have the following drawbacks: the heat preservation barrel is only insulated by a stainless steel inner liner, resulting in poor insulation performance.

[0004] Therefore, there is an urgent need for a non-convective hollow insulation cavity to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the current technical deficiencies and provide a non-convection hollow heat preservation cavity.

[0006] The technical solution adopted by the present invention to achieve the above-mentioned purpose is:

[0007] A non-convection hollow insulation cavity comprises an outer wall, an inner wall and a connecting piece, wherein the outer wall and the inner wall are connected via the connecting piece, the inner wall encloses an accommodating space, and a hollow cavity is formed between the outer wall and the inner wall, a first through hole for inserting a water outlet pipe is provided on the outer wall, and a second through hole for inserting the water outlet pipe is provided on the inner wall, and the first through hole and the second through hole are arranged correspondingly.

[0008] As a further improvement, the hollow cavity is arranged around the periphery of the inner wall.

[0009] As a further improvement, the connecting piece is arranged in the hollow cavity.

[0010] As a further improvement, there are at least two connecting members, which extend along the length direction of the hollow cavity and separate the hollow cavity into a first cavity and a second cavity that are independent of each other.

[0011] As a further improvement, the volume of the first cavity is smaller than the volume of the second cavity, and the first through hole and the second through hole are located between two connecting members used to separate the first cavity.

[0012] As a further improvement, the second cavity is divided into at least two independent parts with the same volume by the connecting piece.

[0013] As a further improvement, the non-convective hollow insulation cavity is an integrated structure.

[0014] As a further improvement, the outer contour of the inner wall is cylindrical.

[0015] As a further improvement, the outer contour of the outer wall is cylindrical.

[0016] As a further improvement, the outer wall, the inner wall, the hollow cavity and the connecting piece are arranged at the same height.

[0017] The beneficial effects of the present invention are as follows: the present invention provides a non-convection hollow heat-insulating chamber, comprising an outer wall, an inner wall, and a connector. The outer wall and the inner wall are connected by the connector. The inner wall encloses a storage space. A hollow chamber is formed between the outer wall and the inner wall. A first through hole for inserting a water outlet pipe is provided on the outer wall. A second through hole for inserting the water outlet pipe is provided on the inner wall.

[0026] Please refer to Figures 1 to 3 The utility model provides a non-convection hollow heat preservation chamber 100, comprising an outer wall 10, an inner wall 20 and a connector 30. The outer wall 10 and the inner wall 20 are connected by the connector 30. The inner wall 20 encloses a receiving space 20a. A hollow chamber 100a is formed between the outer wall 10 and the inner wall 20. A first through hole 10a for inserting a water outlet pipe is provided on the outer wall 10, and a second through hole 20b for inserting a water outlet pipe is provided on the inner wall 20. The first through hole 10a and the second through hole 20b are arranged correspondingly. Figure 3 As shown, as one of the embodiments of the non-convection hollow insulation cavity 100, in actual use, the insulation liner 200 can be installed in the accommodating space 20a, and at the same time, an insulation baffle 300 is installed above and below the non-convection hollow insulation cavity 100 to limit the air flow in the hollow cavity 100a, and the water outlet pipe 400 is inserted into the non-convection hollow insulation cavity 100, thereby achieving a good insulation effect.

[0027] Please continue to refer to Figures 1 to 3 As one of the preferred embodiments, the hollow cavity 100a is arranged around the periphery of the inner wall 20. At this time, the hollow cavity 100a is annular and is arranged around the outer side of the inner wall 20, so that a good thermal insulation effect can be achieved.

[0028] Please continue to refer to Figures 1 to 3The connector 30 is disposed in the hollow cavity 100a. Of course, in other embodiments, part of the connector 30 may also extend outside the hollow cavity 100a. Preferably, there are at least two connectors 30, which extend along the length of the hollow cavity 100a and separate the hollow cavity 100a into a first cavity 101a and a second cavity 102a that are independent of each other. The volume of the first cavity 101a is smaller than that of the second cavity 102a. The first through hole 10a and the second through hole 20b are located between the two connectors 30 used to separate the first cavity 101a. This is because the water outlet pipe is inserted into the first cavity 101a. At this time, the temperature of the first cavity 101a will drop faster than that of the second cavity 102a. In order to avoid the influence of the external environment on the second cavity 102a and to achieve good thermal insulation performance, the volume of the first cavity 101a needs to be set to be smaller than that of the second cavity 102a.

[0029] Please continue to refer to Figures 1 to 3 As one of the preferred embodiments of the present invention, the second cavity 102a is divided into at least two independent parts with the same volume by the connecting member 30, such as Figure 1 As shown in the independent area 1021a shown in FIG. For example, those skilled in the art can divide the second cavity 102a into two, three, or four or more independent areas. This can effectively reduce the impact of temperature changes between the independent areas while achieving uniform thermal insulation of all parts within the accommodating space 20a. Of course, in other embodiments, the volumes of the independent areas divided into the second cavity 102a are different.

[0030] Please continue to refer to Figures 1 to 3 In order to increase the structural strength and thermal insulation effect, the non-convection hollow thermal insulation chamber 100 is an integrated structure, but is not limited to this. In addition, in order to achieve the purposes of uniform thermal insulation, large water storage capacity, and easy cleaning and arrangement, the outer contour of the inner wall 20 is preferably cylindrical, and the outer contour of the outer wall 10 is also cylindrical; of course, those skilled in the art can also set the inner wall 20 and the outer wall 10 to different shapes according to actual needs, so it is not limited to this. In addition, if Figures 1 to 3 As shown, the outer wall 10 , the inner wall 20 , the hollow cavity 100 a and the connecting member 30 are arranged at the same height, but the present invention is not limited thereto.

[0031] It is worth noting that the material of the non-convective hollow insulation chamber 100 of the present invention can be various materials such as plastic and stainless steel, so no further limitation is made here.

[0032] Beneficial effects of the present invention: The present invention provides a non-convection hollow heat-insulating chamber 100, comprising an outer wall 10, an inner wall 20, and a connector 30. The outer wall 10 and the inner wall 20 are connected by the connector 30. The inner wall 20 encloses a receiving space 20a. A hollow chamber 100a is formed between the outer wall 10 and the inner wall 20. A first through hole 10a for inserting a water outlet pipe is provided on the outer wall 10, and a second through hole 20b for inserting a water outlet pipe is provided on the inner wall 20. The first through hole 10a and the second through hole 20b are arranged correspondingly. Therefore, in actual use, the present invention can be used to replace the barrel wall of an ordinary heat-insulating barrel, and the heat-insulating inner liner can be installed in the receiving space 20a. Then, further heat preservation can be achieved through the hollow chamber 100a, so that the overall heat-insulating effect is greatly improved.

[0033] The present invention is not limited to the above-mentioned embodiments. Other non-convection hollow insulation chambers obtained by using the same or similar structures or devices as the above-mentioned embodiments of the present invention are within the protection scope of the present invention.
