Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0032] A hot pot assembly 100 according to an embodiment of the first aspect of the present invention will be described below with reference to the accompanying drawings.

[0033] like Figures 1 to 9 As shown, a hot tank assembly 100 according to an embodiment of the first aspect of the present invention is used in a water dispenser. The hot tank assembly 100 includes: a tank body 1 and an insulation layer 2. A water storage chamber 111 is formed in the tank body 1, and the insulation layer 2 is installed on the outer surface of the tank body 1. In other words, the hot tank assembly 100 stores water through the water storage chamber 111 of the tank body 1, wherein the insulation layer 2 has a good thermal insulation effect. By installing the insulation layer 2 on the outer surface of the tank body 1, the insulation layer 2 can slow down the heat transfer between the water storage chamber 111 and the external space, thereby reducing heat loss in the water storage chamber 111 and improving the thermal insulation effect of the tank body 1. In addition, the activation frequency of the heating assembly 7 of the hot tank assembly 100 for heating the water in the water storage chamber 111 can be reduced. That is, the heating assembly 7 does not need to be frequently activated to heat the water in the water storage chamber 111, thereby reducing the energy consumption of the hot tank assembly 100.

[0034] According to the hot tank assembly 100 of the first embodiment of the present invention, the heat transfer between the water storage chamber 111 and the external space can be slowed down by the insulation layer 2, thereby reducing the heat loss in the water storage chamber 111, thereby improving the insulation effect of the tank body 1, and at the same time reducing the energy consumption of the hot tank assembly 100.

[0035] According to some embodiments of the present invention, the insulation layer 2 surrounds the outer circumference of the tank body 1. That is, the insulation layer 2 is located on the outer circumference of the water storage cavity 111 and extends along the outer circumference of the water storage cavity 111 to form a closed ring. As a result, the insulation layer 2 can completely cover the water storage cavity 111 along the circumference of the tank body 1, thereby enhancing the insulation effect of the insulation layer 2 on the water storage cavity 111. At the same time, the insulation layer 2 can be prevented from occupying the space on both sides of the inner liner 11 in the axial direction of the tank body 1, thereby facilitating the arrangement of water inlet and outlet pipes, the heating assembly 7, and other structures in the axially opposite areas of the inner liner 11.

[0036] In a specific example, the outer peripheral contour of the projection of the inner liner 11 on a plane perpendicular to the axial direction of the tank body 1 is circular. This can greatly simplify the structure of the inner liner 11, thereby reducing the difficulty of processing and forming the inner liner 11. In addition, the inner liner 11 has a higher structural strength, thereby improving the overall structural stability of the tank body 1.

[0037] According to some embodiments of the present invention, the projection of the water storage chamber 111 on the reference plane is the first projection, the projection of the thermal insulation layer 2 on the reference plane is the second projection, the reference plane is parallel to the axial direction of the tank body 1, and the first projection is located inside the second projection in the axial direction of the tank body 1. It should be noted that in the description of this application, when the outer peripheral contour of the tank body 1 is roughly circular, the axial direction of the tank body 1 refers to the extension direction of the central axis of the tank body 1. When the outer peripheral contour of the tank body 1 is non-circular, such as a square, the axial direction of the tank body 1 refers to the extension direction of the tank body 1, such as Figure 1 As shown, the tank body 1 extends in the up-down direction, and the axial direction of the tank body 1 is the up-down direction.

[0038] For the convenience of description, the side of the first projection on one side of the tank body 1 in the axial direction is defined as the first side, the side of the first projection on the other side of the tank body 1 in the axial direction is defined as the second side, the side of the second projection on the axial direction of the tank body 1 adjacent to the first side is defined as the third side, and the side of the second projection on the axial direction of the tank body 1 adjacent to the second side is defined as the fourth side. That is to say, in the axial direction of the tank body 1, the first side does not extend out of the side of the third side away from the fourth side, and the second side does not extend out of the side of the fourth side away from the third side. For example, the first side may overlap with the third side, and the second side may overlap with the fourth side; or the first side may overlap with the third side, and the second side may be located on the side of the fourth side facing the third side; or the first side may be located on the side of the third side facing the third side, and the second side may overlap with the fourth side; or the first side may be located on the side of the third side facing the third side, and the second side may be located on the side of the fourth side facing the third side. Thus, in the axial direction of the tank body 1 , it can be ensured that the thermal insulation layer 2 completely covers the water storage cavity 111 , thereby improving the heat insulation effect of the thermal insulation layer 2 on the water storage cavity 111 .

[0039] According to some embodiments of the present invention, in the axial direction of the can body 1, the two opposite sides of the first projection are respectively the first side and the second side, the side of the second projection adjacent to the first side is the third side, and the side of the second projection adjacent to the second side is the fourth side. The distance between the first side and the third side, and the distance between the second side and the fourth side are both in the range of 2-10 mm. That is, the spacing between the first side and the third side in the axial direction of the can body 1 is controlled within the range of 2 mm to 10 mm, and the spacing between the second side and the fourth side in the axial direction of the can body 1 is also controlled within the range of 2 mm to 10 mm. For example, the spacing between the first side and the third side in the axial direction of the can body 1, and the spacing between the second side and the fourth side in the axial direction of the can body 1 can be 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, etc., without specific limitation here.

[0040] On the basis of the unchanged axial dimension of the tank body 1, the smaller the spacing between the first side and the third side, and the spacing between the second side and the fourth side, the larger the size of the water storage chamber 111 in the axial direction of the tank body 1 can be, but more heat will be dissipated from the parts of the tank body 1 on both sides of the axial direction of the tank body 1 through the thermal insulation layer 2; conversely, the larger the spacing between the first side and the third side, and the spacing between the second side and the fourth side, the smaller the size of the water storage chamber 111 in the axial direction of the tank body 1, but less heat will be dissipated from the parts of the tank body 1 on both sides of the axial direction of the tank body 1 through the thermal insulation layer 2. Therefore, by controlling the distance range between the first side and the third side, and the distance range between the second side and the fourth side within the range of 2mm to 10mm, it is possible to ensure that the water storage chamber 111 has sufficient water storage space while maintaining the thermal insulation effect of the tank body 1.

[0041] According to some embodiments of the present invention, the tank body 1 includes an inner liner 11, a cover plate 12 and a bottom plate 13. A water storage chamber 111 is formed in the inner liner 11, and the inner liner 11 is respectively formed with a first opening 112 and a second opening 113 at both ends in the axial direction of the tank body 1, which are connected to the water storage chamber 111. The cover plate 12 is used to block the first opening 112, and the bottom plate 13 is used to block the second opening 113. The hot tank assembly 100 also includes a top seat 3 and a base 4. The top seat 3 and the tank body 1 define a first insulation chamber 5 located on the upper side of the cover plate 12, and the base 4 and the tank body 1 define a second insulation chamber 6 located on the lower side of the inner bottom wall of the inner liner 11. That is to say, the tank body 1 blocks the first opening 112 through the cover plate 12 and blocks the second opening 113 through the bottom plate 13. The first insulation cavity 5 defined by the top seat 3 and the tank body 1 can reduce the heat loss in the water storage cavity 111 through the cover plate 12. The second insulation cavity 6 defined by the base 4 and the tank body 1 can reduce the heat loss in the water storage cavity 111 through the bottom plate 13. That is, the first insulation cavity 5 and the second insulation cavity 6 can block the heat loss in the water storage cavity 111 from the axial sides of the inner liner 11 on the tank body 1. Therefore, the cooperation of the insulation layer 2, the first insulation cavity 5 and the second insulation cavity 6 can more comprehensively preserve the temperature in the water storage cavity 111, thereby improving the insulation effect of the tank body 1.

[0042] In a specific example, the axial direction of the tank body 1 is parallel to the up-down direction, the thermal insulation layer 2 is cylindrical and extends in the up-down direction, the thermal insulation layer 2 surrounds the outer peripheral side of the inner liner 11, the inner liner 11 is cylindrical and extends in the up-down direction, the upper end of the inner liner 11 is formed with a first opening 112, and the lower end of the inner liner 11 is formed with a second opening 113. The tank body 1 also includes a cover plate 12 and a bottom plate 13. The cover plate 12 is arranged in the first opening 112 of the inner liner 11 and is used to block the first opening 112. The bottom plate 13 is arranged in the second opening 113 of the inner liner 11 and is used to block The second opening 113, the outer peripheral edge of the bottom plate 13 is formed with a downwardly bent flange, the outer peripheral surface of the flange of the bottom plate 13 and the inner peripheral surface of the lower end of the inner liner 11 are stacked and welded along the radial direction of the tank body 1, and the inner liner 11, the cover plate 12 and the bottom plate 13 jointly define a water storage chamber 111, the lower surface of the cover plate 12 is lower than the upper end of the insulation layer 2, and the upper surface of the bottom plate 13 is higher than the lower end of the insulation layer 2, thereby preventing the heat in the water storage chamber 111 from dissipating outward through the upper and lower ends of the insulation layer 2, thereby improving the insulation effect of the insulation layer 2 on the tank body 1.

[0043] In addition, a water inlet is formed on the cover plate 12, through which external water enters the water storage chamber 111. A water outlet is provided on the bottom plate 13, through which the water in the water storage chamber 111 is discharged. In addition, the hot pot assembly 100 also includes a water pump 81 and a water pumping pipe 82. One end of the water pumping pipe 82 is connected to the water outlet, and the other end of the water pumping pipe 82 can be connected to a structure such as a faucet for supplying water to the user. The water pump 81 is installed in the water pumping pipe 82 to drive water out of the water pumping pipe 82.

[0044] According to some embodiments of the present invention, the hot pot assembly 100 further includes a heating assembly 7 disposed within the second insulating cavity 6, and a base 4 constructed of a flame-retardant material. It is understood that the heating assembly 7 generates a significant amount of heat during operation. Therefore, by constructing the base 4 from a flame-retardant material, the base 4's flame retardancy can be enhanced, thereby preventing the spread of high-temperature fires from the heating assembly 7 and improving the safety of the hot pot assembly 100.

[0045] The heating assembly 7 is a heating plate, which is attached to the outer surface of the bottom plate 13. The heating plate heats the bottom plate 13 so that the bottom plate 13 can transfer heat to the water in the water storage chamber 111 to heat the water. Specifically, the bottom plate 13 is a steel plate, and the heating plate is brazed to the bottom surface of the steel plate.

[0046] According to some embodiments of the present invention, the base 4 includes a base body 41 and a plurality of limiting ribs 42 provided on the upper surface of the base body 41. The plurality of limiting ribs 42 are arranged at intervals on the outer circumference of the tank body 1 and together define a limiting space 43 for limiting the position of the tank body 1. Therefore, the plurality of limiting ribs 42 can effectively limit the radial freedom of movement of the tank body 1, thereby improving the stability of the installation position of the tank body 1 on the base 4. In addition, the plurality of limiting ribs 42 arranged at intervals can reduce the weight and cost of the base 4 while ensuring the limiting effect on the tank body 1.

[0047] In a specific example, the top seat 3 is covered at the first opening 112, and a plug-in groove 44 is formed on the side of the chassis facing the tank body 1. The plug-in groove 44 is annular, and the welding positions of the outer liner, the inner liner 11 and the lower end of the bottom plate 13 are plugged into the plug-in groove 44 to prevent the tank body 1 from moving radially relative to the base 4 by limiting the tank body 1 through the plug-in groove 44.

[0048] In some embodiments of the present invention, insulation layer 2 is a vacuum insulation panel. This effectively prevents heat transfer caused by air convection, significantly reducing the panel's thermal conductivity. This significantly enhances the insulation performance of insulation layer 2 and, consequently, the thermal insulation performance of hot pot assembly 100.

[0049] In a specific example, the insulation layer 2 is in the shape of a hollow cylinder extending along the axial direction of the tank body 1, and the insulation layer 2 is sleeved on the cylindrical part of the tank body 1, or the outer peripheral surface of the tank body 1 is in the shape of a cylinder extending along the axial direction of the tank body 1, thereby reducing the difficulty of deformation of the insulation layer 2 to adapt to the shape of the tank body 1.

[0050] According to some embodiments of the present invention, the thickness of the thermal insulation layer 2 is in the range of 4-8 mm. That is, the dimension of the thermal insulation layer 2 in the direction of the wall thickness of the inner liner 11 ( Figure 4 The L shown in FIG is controlled within the range of 4 mm to 8 mm. For example, the thickness of the thermal insulation layer 2 can be 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, and so on, without specific limitation. The thicker the thermal insulation layer 2, the better the thermal insulation effect of the thermal insulation layer 2, but the more space the thermal insulation layer 2 occupies and the higher the cost of use. Conversely, the thinner the thermal insulation layer 2, the worse the thermal insulation effect of the thermal insulation layer 2, but the less space the thermal insulation layer 2 occupies and the lower the cost of use. Therefore, controlling the thickness of the thermal insulation layer 2 within the range of 4 mm to 8 mm can ensure the thermal insulation effect of the thermal insulation layer 2 while controlling the cost of use of the thermal insulation layer 2.

[0051] According to some embodiments of the present invention, the thermal insulation layer 2 is adhesively connected to the tank body 1. The adhesive connection ensures connection stability without requiring additional connection components, requiring only the application of adhesive on the inner side of the thermal insulation layer 2 or the outer surface of the tank body 1. Furthermore, the adhesive connection is applicable to connecting structures of various shapes, i.e., to thermal insulation layers 2 and tank bodies 1 of various shapes, and is easy to operate and highly efficient.

[0052] The following describes a water dispenser according to an embodiment of the second aspect of the present utility model with reference to the accompanying drawings.

[0053] The water dispenser according to the second embodiment of the present invention includes: a hot tank assembly 100.

[0054] According to the water dispenser of the second embodiment of the present invention, the heat transfer between the water storage chamber 111 and the external space can be slowed down by the insulation layer 2, thereby reducing the heat loss in the water storage chamber 111, thereby improving the insulation effect of the tank body 1, and at the same time reducing the energy consumption of the hot tank assembly 100.

[0055] The water dispenser can be a water purifier, a water purifier, or any water-using device with a heating or cooling function. In one embodiment, the water dispenser is an all-in-one water purifier and heat dispenser. Specifically, the water dispenser further includes a water purification module, the water outlet of which is connected to the water storage chamber 111. Therefore, the water purification module can transfer purified water to the hot tank assembly 100 for heating to provide hot, pure drinking water to the user. In other words, the water dispenser can simultaneously purify and heat water, which can effectively improve the integration of the water dispenser and reduce the space occupied by the additional water purifier.
