To simplify the disclosure of the present utility model, components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present utility model.

[0035] The hot water tank assembly 100 according to an embodiment of the first aspect of the present utility model will be described below with reference to the accompanying drawings.

[0036] As Figures 1 to 9 shown, the hot water tank assembly 100 according to an embodiment of the first aspect of the present utility model is for a water dispenser. The hot water tank assembly 100 includes: a tank body 1. A water storage cavity 11 is formed inside the tank body 1. A vacuum insulation cavity 12 is formed inside the wall of the water storage cavity 11. In the wall thickness direction of the water storage cavity 11, the size ( Figure 4 L shown therein) of the vacuum insulation cavity 12 is not less than 4.5 mm. That is to say, at least part of the water storage cavity 11 is separated from the external space of the tank body 1 by the vacuum insulation cavity 12. Among them, the inside of the vacuum insulation cavity 12 is in a vacuum state. By evacuating the air inside the vacuum insulation cavity 12, heat transfer caused by air can be better reduced, that is, convective heat transfer can be better reduced, so that the heat loss inside the water storage cavity 11 can be reduced. And by setting the size of the vacuum insulation cavity 12 in the wall thickness direction of the water storage cavity 11 to be equal to 4.5 mm or greater than 4.5 mm, the heat insulation effect of the vacuum insulation cavity 12 can be improved, so that the heat transfer between the water storage cavity 11 and the external space can be slowed down, and further the heat preservation effect of the tank body 1 can be improved.

[0037] For the hot water tank assembly 100 according to an embodiment of the first aspect of the present utility model, a water storage cavity 11 is formed inside the tank body 1, and a vacuum insulation cavity 12 is formed inside the wall of the water storage cavity 11. In the wall thickness direction of the water storage cavity 11, the size of the vacuum insulation cavity 12 is not less than 4.5 mm, which can improve the heat insulation effect of the vacuum insulation cavity 12, so that the heat transfer between the water storage cavity 11 and the external space can be slowed down to reduce the heat loss inside the water storage cavity 11, and further the heat preservation effect of the tank body 1 can be improved.

[0038] In addition, by reducing the heat loss in the water storage cavity 11, the opening frequency of the heating component 6 for heating the water in the water storage cavity 11 can be reduced. That is, the heating component 6 does not need to frequently turn on to heat the water in the water storage cavity 11, thereby reducing the energy consumption of the hot water tank assembly 100.

[0039] According to some embodiments of the present invention, the dimension of the vacuum insulation cavity 12 in the wall thickness direction of the water storage cavity 11 is not greater than 8 mm. That is, the dimension of the vacuum insulation cavity 12 in the wall thickness direction of the water storage cavity 11 ( Figure 4 L shown therein) is controlled within the range of 4.5 mm to 8 mm. For example, the dimension of the vacuum insulation cavity 12 in the wall thickness direction of the water storage cavity 11 can be 4.5 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, etc., and no specific limitation is made here. It can be understood that, on the basis of the unchanged size of the tank body 1, the smaller the dimension of the vacuum insulation cavity 12 in the wall thickness direction of the water storage cavity 11, the larger the space reserved for the water storage cavity 11, and the larger the water storage capacity of the water storage cavity 11, but the worse the heat insulation effect of the vacuum insulation cavity 12 and the worse the heat preservation performance of the tank body 1; on the contrary, the larger the dimension of the vacuum insulation cavity 12 in the wall thickness direction of the water storage cavity 11, the smaller the space reserved for the water storage cavity 11, and the smaller the water storage capacity of the water storage cavity 11, but the stronger the heat insulation effect of the vacuum insulation cavity 12 and the stronger the heat preservation performance of the tank body 1.

[0040] Therefore, controlling the dimension of the vacuum insulation cavity 12 in the wall thickness direction of the water storage cavity 11 within the range of 4.5 mm to 8 mm can avoid the too small dimension of the vacuum insulation cavity 12 in the wall thickness direction of the water storage cavity 11 from affecting the heat insulation effect of the vacuum insulation cavity 12, and at the same time can avoid the too large dimension of the vacuum insulation cavity 12 in the wall thickness direction of the water storage cavity 11 from resulting in too small a volume of the water storage cavity 11, thereby increasing the water storage capacity of the tank body 1 while ensuring the heat preservation effect of the tank body 1.

[0041] According to some embodiments of the present invention, the dimension range of the vacuum insulation cavity 12 in the wall thickness direction of the water storage cavity 11 is 5 - 5.4 mm. That is, the dimension of the vacuum insulation cavity 12 in the wall thickness direction of the water storage cavity 11 is controlled within the range of 5 mm to 5.4 mm. For example, the dimension of the vacuum insulation cavity 12 in the wall thickness direction of the water storage cavity 11 can be 5 mm, 5.1 mm, 5.15 mm, 5.2 mm, 5.25 mm, 5.3 mm, 5.35 mm, 5.4 mm, etc., and no specific limitation is made here. Therefore, the requirement for the balance between the heat preservation effect and the water storage capacity of the tank body 1 can be further met.

[0042] According to some embodiments of the present utility model, the tank body 1 includes an outer tank 13 and an inner tank 14 disposed within the outer tank 13. The water storage cavity 11 is located within the inner tank 14, and the outer tank 13 and the inner tank 14 jointly define a vacuum insulation cavity 12. That is to say, a cavity isolated from the external space and the water storage cavity 11 is jointly defined between the inner side surface of the outer tank 13 and the outer side surface of the inner tank 14, and the vacuum insulation cavity 12 is formed by evacuating the sealed cavity between the outer tank 13 and the inner tank 14. Therefore, when hot water is stored in the water storage cavity 11, since the vacuum insulation cavity 12 is in a vacuum state, the heat of the hot water in the inner tank 14 can be prevented from dissipating outward through gas convection, that is, the heat dissipation of the hot water through the tank body 1 can be reduced through the vacuum insulation cavity 12 to improve the heat preservation effect of the tank body 1 on the hot water.

[0043] In a specific example, the outer peripheral contours of the projections of the outer tank 13 and the inner tank 14 on a plane perpendicular to the axial direction of the tank body 1 are circular. Thereby, the structures of the outer tank 13 and the inner tank 14 can be preferably simplified, thereby reducing the processing and forming difficulty of the outer tank 13 and the inner tank 14. In addition, the outer tank 13 and the inner tank 14 have higher structural strength, thereby improving the overall structural stability of the tank body 1.

[0044] According to some embodiments of the present utility model, the projection of the water storage cavity 11 on a reference plane is a first projection, and the projection of the vacuum insulation cavity 12 on the reference plane is a second projection. The reference plane is parallel to the axial direction of the tank body 1. In the axial direction of the tank body 1, the first projection is located within the second projection. It should be noted that in the description of the present application, when the outer peripheral contour of the tank body 1 is approximately circular, the axial direction of the tank body 1 refers to the extending 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 square, the axial direction of the tank body 1 refers to the extending direction of the tank body 1. As Figure 1 shown, the tank body 1 extends in the up and down direction, and the axial direction of the tank body 1 is the up and down direction.

[0045] For ease of description, the side on one side of the first projection in the axial direction of the tank body 1 is defined as the first side, the side on the other side of the first projection in the axial direction of the tank body 1 is defined as the second side, the side of the second projection adjacent to the first side in the axial direction of the tank body 1 is defined as the third side, and the side of the second projection adjacent to the second side in the axial direction of the tank body 1 is defined as the fourth side. That is, in the axial direction of the tank body 1, the first side does not extend beyond the side of the third side away from the fourth side, and the second side does not extend beyond 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 vacuum insulation cavity 12 completely covers the water storage cavity 11, thereby improving the heat insulation effect of the vacuum insulation cavity 12 on the water storage cavity 11.

[0046] According to some embodiments of the present invention, in the axial direction of the tank body 1, the two side edges opposite to 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 range between the first side and the third side and the distance range between the second side and the fourth side are both 2 - 10 mm. That is, the axial spacing between the first side and the third side in the tank body 1 is controlled within the range of 2 mm to 10 mm, and at the same time, the axial spacing between the second side and the fourth side in the tank body 1 is also controlled within the range of 2 mm to 10 mm. For example, the axial spacing between the first side and the third side in the tank body 1 and the axial spacing between the second side and the fourth side in the tank body 1 can be 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, etc., and no specific limitation is made here.

[0047] Among them, on the basis that the axial dimension of the tank body 1 remains unchanged, the smaller the distance between the first side and the third side and the distance between the second side and the fourth side are, the larger the size of the water storage cavity 11 can be in the axial direction of the tank body 1. However, the more heat is dissipated through the parts of the tank body 1 on both sides of the vacuum insulation cavity 12 in the axial direction of the tank body 1. On the contrary, the larger the distance between the first side and the third side and the distance between the second side and the fourth side are, the smaller the size of the water storage cavity 11 is in the axial direction of the tank body 1, but the less heat is dissipated through the parts of the tank body 1 on both sides of the vacuum insulation cavity 12 in the axial direction of the tank body 1. 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 2 mm to 10 mm, it is possible to ensure the heat preservation effect of the tank body 1 while ensuring that the water storage cavity 11 has sufficient water storage space.

[0048] According to some embodiments of the present invention, both the inner tank 14 and the outer tank 13 are metal parts. It can be understood that the metal parts have good structural strength and high temperature resistance, and at the same time have good plasticity. Therefore, the structural strength of the tank body 1 can be improved preferably, and the requirement of the inner tank 14 for storing hot water can be met. At the same time, the outer tank 13 made of metal can provide better protection for the inner tank 14. Secondly, the requirements for different shapes of the tank body 1 can be met through the good plasticity of the metal parts.

[0049] According to some embodiments of the present invention, on the axial direction of the tank body 1, both ends of the outer tank 13 are welded to both ends of the inner tank 14 respectively. That is to say, the outer tank 13 and the inner tank 14 are connected by welding, which can save the components for connecting the outer tank 13 and the inner tank 14 and steps such as punching, thereby reducing the production cost of the tank body 1 and improving the production efficiency of the tank body 1. At the same time, good sealing performance can be provided through welding, so as to improve the sealing performance of the vacuum insulation cavity 12 to ensure the heat insulation effect of the vacuum insulation cavity 12.

[0050] According to some embodiments of the present invention, the inner tank 14 and the outer tank 13 are made of the same material. Thus, the types of materials required for processing and producing the inner tank 14 and the outer tank 13 can be reduced preferably. That is, only one type of material, such as stainless steel, needs to be purchased when producing the inner tank 14 and the outer tank 13, which can reduce the management difficulty of production materials.

[0051] In a specific example, the axial direction of the tank body 1 is parallel to the up-and-down direction. The outer tank 13 is in the shape of a cylinder penetrating in the up-and-down direction. The outer tank 13 surrounds the outer peripheral side of the inner tank 14. The inner tank 14 is in the shape of a cylinder extending in the up-and-down direction. A first opening 111 is formed at the upper end of the inner tank 14, and a second opening 112 is formed at the lower end of the inner tank 14. The tank body 1 further includes a cover plate 15 and a bottom plate 16. The cover plate 15 is arranged in the first opening 111 of the inner tank 14 and is used to seal the first opening 111. The bottom plate 16 is arranged in the second opening 112 of the inner tank 14 and is used to seal the second opening 112. A downward-bent flange is formed at the outer peripheral edge of the bottom plate 16. The outer peripheral surface of the flange of the bottom plate 16 and the inner peripheral surface of the lower end of the inner tank 14 are arranged in a stacked manner along the radial direction of the tank body 1 and are welded together. The outer peripheral surface of the lower end of the inner tank 14 and the inner peripheral surface of the lower end of the outer tank 13 are arranged in a stacked manner along the radial direction of the tank body 1 and are welded together. At the same time, the outer peripheral surface of the upper end of the inner tank 14 and the inner peripheral surface of the upper end of the outer tank 13 are arranged in a stacked manner along the radial direction of the tank body 1 and are welded together. Thus, a sealed cavity can be formed between the outer tank 13 and the inner tank 14. By evacuating the sealed cavity between the outer tank 13 and the inner tank 14, a vacuum insulation cavity 12 is formed. The inner tank 14, the cover plate 15, and the bottom plate 16 jointly define a water storage cavity 11. The lower surface of the cover plate 15 is lower than the welding position of the upper ends of the outer tank 13 and the inner tank 14, and the upper surface of the bottom plate 16 is higher than the welding position of the lower ends of the outer tank 13 and the inner tank 14. Thus, the heat in the water storage cavity 11 can be prevented from dissipating outward through the welding positions of the outer tank 13 and the inner tank 14, so as to improve the heat preservation effect of the tank body 1.

[0052] According to some embodiments of the present invention, the vacuum insulation cavity 12 surrounds the outer peripheral side of the water storage cavity 11. That is to say, the vacuum insulation cavity 12 is located on the outer peripheral side of the water storage cavity 11 and extends along the outer periphery of the water storage cavity 11 to form a closed ring. Thus, in the circumferential direction of the tank body 1, the vacuum insulation cavity 12 can completely cover the water storage cavity 11 to improve the heat insulation effect of the vacuum insulation cavity 12 on the water storage cavity 11. At the same time, the space on both sides of the inner tank 14 in the axial direction of the tank body 1 can be avoided from being occupied by the vacuum insulation cavity 12, so as to facilitate the arrangement of structures such as the water inlet and outlet pipelines and the heating component 6 in the areas on both sides of the inner tank 14 in the axial direction.

[0053] According to some embodiments of the present utility model, first openings 111 and second openings 112 communicating with the water storage cavity 11 are respectively formed at both ends of the inner tank 14 in the axial direction of the tank body 1. The tank body 1 further includes a cover plate 15 for blocking the first opening 111 and a bottom plate 16 for blocking the second opening 112. The hot water tank assembly 100 further includes a top seat 2 and a bottom seat 3. The top seat 2 and the tank body 1 define a first heat insulation cavity 4 above the cover plate 15, and the bottom seat 3 and the tank body 1 define a second heat insulation cavity 5 below the inner bottom wall of the inner tank 14. That is to say, the tank body 1 blocks the first opening 111 through the cover plate 15 and blocks the second opening 112 through the bottom plate 16. The first heat insulation cavity 4 defined by the top seat 2 and the tank body 1 can reduce the loss of heat in the water storage cavity 11 to the outside through the cover plate 15, and the second heat insulation cavity 5 defined by the bottom seat 3 and the tank body 1 can reduce the loss of heat in the water storage cavity 11 to the outside through the bottom plate 16. That is, through the first heat insulation cavity 4 and the second heat insulation cavity 5, the heat in the water storage cavity 11 can be blocked from dissipating to the outside on both sides of the inner tank 14 in the axial direction of the tank body 1. Thus, through the cooperation of the vacuum heat insulation cavity 12, the first heat insulation cavity 4 and the second heat insulation cavity 5, the temperature in the water storage cavity 11 can be stored more comprehensively, so as to improve the heat preservation effect of the tank body 1.

[0054] In a specific example, a water inlet is formed on the cover plate 15, and external water sources enter the water storage cavity 11 through the water inlet. A water outlet is provided on the bottom plate 16, and the water in the water storage cavity 11 is discharged through the water outlet. In addition, the hot water tank assembly 100 further includes a water pump 71 and a water pipe 72. One end of the water pipe 72 is communicated with the water outlet, and the other end of the water pipe 72 can be connected to a structure such as a faucet for supplying water to users. The water pump 71 is arranged on the water pipe 72 to drive the water flow to be discharged from the water pipe 72.

[0055] According to some embodiments of the present utility model, the hot water tank assembly 100 further includes a heating assembly 6, and the heating assembly 6 is arranged in the second heat insulation cavity 5. The bottom seat 3 is made of a flame retardant material. It can be understood that a large amount of heat will be generated during the operation of the heating assembly 6. Therefore, by using a flame retardant material to make the bottom seat 3, the flame retardant ability of the bottom seat 3 can be improved, so as to avoid the spread of high-temperature fire caused by the heating assembly 6, and thus improve the safety of the hot water tank assembly 100.

[0056] Among them, the heating assembly 6 is a heating plate, and the heating plate is attached to the outer side surface of the bottom plate 16. The bottom plate 16 is heated by the heating plate so that the bottom plate 16 can transfer heat to the water in the water storage cavity 11 to realize the heating of the water. Specifically, the bottom plate 16 is a steel plate, and the heating plate is brazed to the bottom surface of the steel plate.

[0057] According to some embodiments of the present utility model, the base 3 includes a base body 31 and a plurality of limiting edges 32 disposed on the upper surface of the base body 31. The plurality of limiting edges 32 are arranged at intervals on the outer peripheral side of the tank body 1 and jointly define a limiting space 33 for limiting the tank body 1. Therefore, the plurality of limiting edges 32 can preferably limit the freedom of movement of the tank body 1 in the radial direction, thereby improving the stability of the installation position of the tank body 1 on the base 3. In addition, the arrangement of the plurality of limiting edges 32 at intervals can, while ensuring the limiting effect on the tank body 1, reduce the weight and cost investment of the base 3.

[0058] In a specific example, the top seat 2 covers the first opening 111, and a plug-in groove 34 is formed on the side surface of the chassis facing the tank body 1. The plug-in groove 34 is annular, and the welding positions of the outer tank 13, the inner tank 14, and the lower end of the bottom plate 16 are inserted into the plug-in groove 34 to prevent the tank body 1 from moving radially relative to the base 3 through the plug-in groove 34.

[0059] The water dispenser according to the second aspect embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0060] The water dispenser according to the second aspect embodiment of the present utility model includes a hot tank assembly 100.

[0061] The water dispenser according to the second aspect embodiment of the present utility model can improve the heat insulation effect of the vacuum heat insulation cavity 12, thereby slowing down the heat transfer between the water storage cavity 11 and the external space to reduce the heat dissipation in the water storage cavity 11, and further improving the heat preservation effect of the tank body 1.

[0062] Among them, the water dispenser can be a water purifier, a water purifying and drinking machine, or any water-using device with a heating function or a refrigerating function. In a specific embodiment, the water dispenser is a combined hot and purified water machine. Specifically, the water dispenser further includes a water purification module, and the water outlet of the water purification module is communicated with the water storage cavity 11. Therefore, the water purification module can convey the purified water into the hot tank assembly 100 for heating to provide hot purified drinking water for users. That is, the water dispenser can simultaneously purify and heat water, which can preferably improve the integration degree of the water dispenser to reduce the space occupied by additionally using a water purifier.

[0063] In the present utility model, unless otherwise clearly specified and defined, the terms "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense.
