Description

Technical Field

[0001] This utility model relates to water dispensers, and more particularly to a heating tank. Background Technology

[0002] Currently, there are two common types of heating tanks for car water dispensers on the market. The first type uses stainless steel welded into a tank body, with the inlet, outlet, and vent all fully sealed. A heating element is welded to the inside of the bottom of the tank body, and insulation cotton is wrapped around the tank body to keep the hot water warm. An external device enables the heating tank to automatically fill with water. The second type uses upper and lower plastic shells ultrasonically welded together, with inlet, outlet, and vent reserved. A heating element is embedded inside the shell, and a heating film is wrapped around the outside of the shell for insulation. At the same time, a resistive sensor is embedded inside the shell to detect the water level and determine whether there is a shortage of water in the tank so as to replenish it.

[0003] However, the first structure, which wraps the tank with insulation cotton, does not keep the heating tank completely warm, resulting in frequent heating starts of the water dispenser; the second structure, which wraps the shell with a heating film for insulation, results in high power consumption of the water dispenser.

The heating tank 1 has a water outlet 11 at one end and an opening 12 at the other end; the base 2 is located at one end of the heating tank 1; the top cover assembly 3 is connected to the other end of the heating tank 1 and covers the opening 12, and the top cover assembly 3 has a water inlet 31 and a vent 32 communicating with the heating tank 1; one end of the connecting frame 4 is connected to the base 2, and the other end is connected to the top cover assembly 3; one end of the water outlet pipe 5 is connected to the water outlet 11, and the other end passes through and extends out of the base 2; the heating pipe 6 is connected to the heating tank 1 and is located between the heating tank 1 and the base 2; wherein, the top cover assembly 3 has a first receiving cavity 33, and the first receiving cavity 33 has a first heat insulation layer 331; the connecting frame 4 and the base 2 form a second receiving cavity 7 between the heating tank 1 and the connecting frame 4, the base 2, and the heating tank 1, and the second receiving cavity 7 has a second heat insulation layer 71.

[0024] In this embodiment of the utility model, the heating tank 1 is provided with a water outlet 11 and an opening 12, and the upper cover assembly 3 is provided with a water inlet 31 and an exhaust outlet 32 ​​that connect the heating tank 1, which helps the heating tank to enter and exit water and exhaust air, so that the heating tank can work normally. The heating tube 6 is used to heat the heating tank 1, and the heating tube 6 is located between the heating tank 1 and the base 2, which can prevent heat loss.

[0025] Understandably, the upper cover assembly 3 and the base 2 are connected together by the connecting frame 4, sealing the heating element 1 between the upper cover assembly 3 and the base 2, thus achieving a sealing effect on the heating element 1. The upper cover assembly 3 and the base 2 form a structure similar to a thermos cup, which can effectively keep the heating element 1 warm. Moreover, a first insulation layer 331 is provided in the first receiving cavity 33 formed by the upper cover assembly 3, and a second insulation layer 71 is provided in the second receiving cavity 7 formed between the connecting frame 4, the base 2 and the heating element 1, forming an insulation layer similar to a thermos cup. Insulation material is filled in the first insulation layer 331 and the second insulation layer 71 to further seal and keep the heating element 1 warm, resulting in a better heat preservation effect of the heating tank. It eliminates the need for frequent heating of the heating tank and solves the problems of poor heat preservation or high power consumption in existing heating tanks.

[0026] In some embodiments, the cover assembly 3 includes an inner plate 34 and a cover plate 35, the inner plate 34 covering the opening 12; the cover plate 35 is connected to the inner plate 34, and a first receiving cavity 33 is formed between the cover plate 35 and the inner plate 34.

[0027] In this embodiment, the upper cover assembly 3 is configured as a two-layer structure consisting of an inner plate 34 and a cover plate 35. This not only effectively seals the heating element 1, but also forms a first receiving cavity 33 between the cover plate 35 and the inner plate 34, which is convenient for accommodating the first insulation layer 331. The first insulation layer 331 is filled with insulation material, and together with the second insulation layer 71, it can provide all-round insulation for the heating element 1.

[0028] In some embodiments, the cover assembly 3 further includes a sealing strip 36 disposed between the inner plate 34 and the opening 12.

[0029] In this embodiment, the sealing strip 36 effectively seals the inner plate 34 and the opening 12, preventing liquid from overflowing from the heating tank 1 and preventing heat loss, thereby further improving the heat preservation effect of the heating tank. Specifically, the sealing strip 36 is made of silicone material, and the contact between the silicone sealing strip 36 and the liquid inside the heating tank 1 will not harm the health of the drinker.

[0030] In some embodiments, the water outlet pipe 5 is a silicone water outlet pipe 5, which penetrates the second insulation layer 71.

[0031] In this embodiment, the water outlet pipe 5 is connected to the liquid in the heating tank 1. The water outlet pipe 5 made of silicone material can isolate the second insulation layer 71 from the liquid in the heating tank 1, thereby preventing the second insulation layer 71 from contaminating the liquid and protecting the health of the drinker.

[0032] In some embodiments, the heating tank further includes: a water inlet pipe (not shown), which is a silicone water inlet pipe that penetrates the first insulation layer 331, with one end of the water inlet pipe connected to the water inlet 31 and the other end connected to the opening 12.

[0033] In this embodiment, the water inlet pipe is used to connect the top cover assembly 3 and the heating tank 1, which helps to replenish the liquid in the heating tank 1. The water inlet pipe made of silicone material can isolate the first insulation layer 331 from the liquid in the heating tank 1, thereby preventing the first insulation layer 331 from contaminating the liquid and thus protecting the health of the drinker.

[0034] In some embodiments, the heating tank further includes: an exhaust pipe temperature sensor, the exhaust pipe being a silicone exhaust pipe that penetrates the first insulation layer 331, with one end of the exhaust pipe connected to an exhaust port 32 and the other end connected to an opening 12.

[0035] In this embodiment, the exhaust pipe is used to connect the top cover assembly 3 and the heating tank 1, which helps to maintain the pressure between the heating tank 1 and the outside world, and ensures that the water inlet and outlet of the heating tank are normal. The silicone material exhaust pipe can isolate the first insulation layer 331 from the liquid in the heating tank 1, thereby preventing the first insulation layer 331 from contaminating the liquid and thus protecting the health of the drinker.

[0036] It is understood that in some embodiments, both the first insulation layer 331 and the second insulation layer 71 are made of polymer materials. Since the water outlet pipe 5, the water inlet pipe, and the exhaust pipe are all made of silicone, and these pipes penetrate the insulation layer, they isolate the insulation layer from the liquid inside the heating tank 1, thus preventing contamination of the liquid by the insulation layer and protecting the health of the drinker. Specifically, both the first insulation layer 331 and the second insulation layer 71 are made of polyurethane. Polyurethane has good sealing and insulation properties, effectively keeping the liquid inside the heating tank 1 warm.

[0037] In some embodiments, the heating tank further includes a liquid level sensor 8, which is disposed inside the heating tank 1, with one end of the liquid level sensor 8 facing one end of the heating tank 1 and the other end penetrating through the inner plate 34 and inserted into the first insulation layer 331.

[0038] In this embodiment, the liquid level sensor 8 is used to detect the liquid level in the heating tank 1. One end of the liquid level sensor 8 faces one end of the heating tank 1. Even when the heating tank 1 is short of water, the liquid level can be detected in time and the information can be fed back to the outside. This helps to add liquid to the heating tank in time and prevent damage to the heating tank caused by insufficient liquid inside.

[0039] In a specific embodiment, the cover plate 35, the inner plate 34, and the liquid level sensor 8 are formed by foaming polymerization. Foaming polymerization can improve the sealing of the heating tank, prevent liquid leakage, and further improve the overall heat preservation performance of the heating tank.

[0040] In some embodiments, the heating tank further includes a temperature sensor 9, which is attached to the outside of the heating chamber 1 and located within the second insulation layer 71.

[0041] In this embodiment, the temperature sensor 9 is used to detect the temperature of the liquid inside the heating tank 1, which helps to heat the liquid inside the heating tank 1 in a timely manner, thereby ensuring the temperature of the liquid inside the heating tank.

[0042] In some embodiments, the heating tube 6 is spiral-shaped (not shown) and coiled between the heating element 1 and the base 2.

[0043] In this embodiment, the spiral heating tube 6 can improve the heating effect of the heating tube 6 on the heating tank 1. Moreover, the heating tube 6 is coiled between the heating tank 1 and the base 2 to prevent heat loss, thereby slowing down the cooling rate of the liquid inside the heating tank 1 and improving the heat preservation effect of the heating tank.

[0044] In other embodiments, the heating tube 6 is wavy (not shown) and is attached between the heating element 1 and the base 2.

[0045] In this embodiment, the wavy heating tube 6 can improve the heating effect of the heating tube 6 on the heating tank 1. Moreover, the heating tube 6 is attached between the heating tank 1 and the base 2 to prevent heat loss, thereby slowing down the cooling rate of the liquid inside the heating tank 1 and improving the heat preservation effect of the heating tank.

[0046] In some embodiments, the connecting frame 4 has a first connecting part 41 at one end and a second connecting part 42 at the other end. The first connecting part 41 is connected to the base 2, and the second connecting part 42 is connected to the top cover assembly 3.

[0047] In this embodiment, the first connecting part 41 is connected to the base 2, and the second connecting part 42 is connected to the top cover assembly 3, which helps to improve the overall sealing of the heating tank. The top cover assembly 3 and the base 2 form a structure similar to a thermos cup, which can effectively keep the heating chamber 1 warm, thereby improving the heat preservation effect of the heating tank.

[0048] In a specific embodiment, the first connecting part 41 and the base 2 are detachably fastened together, and the upper cover assembly 3 is detachably covered on the second connecting part 42. The upper cover assembly 3, the connecting frame 4, and the base 2 are all detachable, which facilitates the removal of the heating tank 1 and the heating tube 6, and makes it convenient for the maintenance and replacement of the internal components of the heating tank.

[0049] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model.
