Description

Technical Field

[0001] The present disclosure relates to the technical field of heat pumps, and in particular to a water tank assembly and a water heater. Background Art

[0002] With the development of social economy and the improvement of people's living standards, air-energy water heaters, as the fourth generation of water heaters, have gradually entered thousands of households due to their comfort, environmental protection, energy saving and other advantages. More and more air-energy water heaters are composed of indoor and outdoor units, and the heat exchange speed with the environment is slow, and they need to be equipped with large-capacity water tanks (about 40 to 50L per person).

[0003] Due to the large area occupied, more and more people install products in open places such as rooftops and balconies, which means that the products are exposed to harsh working conditions such as wind, sun, and rain, and require regular maintenance and inspection. Once internal components corrode and fail, the product will be damaged and scrapped.

[0004] Conventional sealing treatment is to use soft materials such as silicone rubber, soft plastic, sponge, etc. to fill the assembly gap to prevent overflow, and sealants are also used to further enhance reliability. However, this treatment method still has high assembly consistency requirements, low efficiency, and potential failure risks due to long-term aging.

[0005] Since the heat pump water tank in the prior art uses soft materials such as silicone rubber, soft plastic, sponge, etc. to fill the assembly gap inside the water tank to prevent overflow, water can still flow into the internal area of ​​the water tank through the assembly gap, resulting in poor sealing effect, which can easily lead to corrosion and failure of internal components of the water tank, and the thermal insulation effect is still not ideal. Therefore, the present invention studies and designs a water tank assembly and a water heater. Summary of the invention

[0042] like Figure 1-3 As shown, the present disclosure provides a water tank assembly, which includes:

[0043] An outer shell 1 and an inner shell 2, wherein the inner shell 2 is arranged inside the outer shell 1, and the outer shell 1 is provided with a water inlet 11 and a water outlet 12, through which water can flow into the inner shell 2, and through which water in the inner shell 2 can be discharged;

[0044] The water tank assembly further includes a first sealing component 31 (the water inlet refers to a pipe joint or other components in the water inlet hole) disposed on the outer periphery of the water inlet 11, and the first sealing component 31 is inserted into the outer periphery of the water inlet 11 from the outside of the shell 1 toward the inside of the shell 1; and / or, the water tank assembly further includes a second sealing component 32 (the water outlet refers to a pipe joint or other components in the water outlet hole) disposed on the outer periphery of the water outlet 12, and the second sealing component 32 is inserted into the outer periphery of the water outlet 12 from the outside of the shell 1 toward the inside of the shell 1;

[0045] The water tank assembly also includes a foaming material 4 filled between the outer shell 1 and the inner tank 2, and the foaming material 4 can flow to the periphery of the water inlet 11 in a liquid state and foam into shape, and / or the foaming material 4 can flow to the periphery of the water outlet 12 in a liquid state and foam into shape.

[0046] The present invention can effectively seal the water inlet and the water outlet from the outside to the inside by arranging the first and second sealing components at the water inlet and the water outlet from the outside to the inside of the shell, and can effectively seal the water inlet and the water outlet by combining the foaming material filled between the inner tank and the shell, and flowing the foaming material to the outer periphery of the water inlet for foaming molding, and flowing the foaming material to the outer periphery of the water outlet for foaming molding, so as to effectively seal the water inlet and the water outlet. Compared with the existing method of arranging materials such as silicone rubber inside the shell to prevent overflow, the present invention can effectively seal the water inlet and the water outlet by using the first and second sealing components outside. The water inlet and the water outlet play an effective role in preventing material from overflowing. At the same time, the internally flowing foamed material entering the periphery of the water inlet and the water outlet can effectively ensure the sealing effect of the water inlet and the water outlet. There will be no assembly gap, which effectively prevents water from entering the water tank from the outside through the assembly gap and causing corrosion of components (such as working fluid pipe joints, temperature sensing packages, water pipe joints and microchannel heat exchangers, refrigerant pipelines and inner tanks, etc.), thereby improving the sealing effect. In addition, the foamed material disclosed in the present invention is filled to the periphery of the water inlet and the water outlet, which greatly improves the thermal insulation performance.

[0047] The present invention provides a new rainproof water tank product, which can fill all gaps with the fluidity of polyurethane foam to wrap all surfaces of the product, avoid the pipe seat and the surface from contacting the outside world, achieve integrated sealing, and fundamentally waterproof and heat-insulating. The foaming material of the present invention adopts hard polyurethane foam material, and the closed-cell rate of the material is greater than 95%, which can seal and block water. At the same time, since the foaming material is in a fluid state before pouring, it can penetrate all pores and flow into and fill all gaps. After a certain period of reaction and maturation, it becomes hard foam, forming an overall water-blocking and sealing effect on all interfaces of the water tank.

[0048] The present invention eliminates the existing method of preventing overflow by arranging silicone rubber, sponge, etc. in the shell, and uses foaming material to wrap and fill all the gaps between the inner liner and the outer shell to achieve overall water blocking; at the same time, the overall polyurethane is used to wrap the surface of the inner liner as a whole, and its heat dissipation area is reduced by about 1% to 10% compared with the existing technical solutions, and is concentrated in the bottom heating area, and the thermal insulation performance is improved by about 10%.

[0049] In some embodiments, the first sealing component 31 is a rubber structure, and the second sealing component 32 is a rubber structure; and / or,

[0050] The water tank assembly further includes a first fastener 61 , which fastens the first sealing component 31 to the housing 1 ; the water tank assembly further includes a second fastener 62 , which fastens the second sealing component 32 to the housing 1 .

[0051] This is the preferred structural form of the first sealing component and the second sealing component of the present invention. The rubber structure can effectively play a sealing and heat-insulating effect to prevent water from entering the interior from the inner wall of the hole and causing corrosion of internal components. The present invention can also fasten the first sealing component through a first fastener arranged at the water inlet, further improve the anti-overflow effect of the water inlet, and ultimately improve the sealing performance and heat-insulating performance of the water inlet. The present invention can also fasten the second sealing component through a second fastener arranged at the water outlet, further improve the anti-overflow effect of the water outlet, and ultimately improve the sealing performance and heat-insulating performance of the water outlet.

[0052] In some embodiments, when the water tank assembly further includes a first fastener 61 and a second fastener 62: the first fastener 61 is an injection molded part; the second fastener 62 is an injection molded part. This is the preferred structural form of the first fastener and the second fastener of the present disclosure, preferably a rubber ring.

[0053] In some embodiments, the water tank assembly also includes a temperature sensing component 5 and a third sealing component 33. The outer shell 1 is also provided with a temperature sensing port 13. The temperature sensing component 5 is inserted into the temperature sensing port 13 from the outside of the outer shell 1 toward the inside of the outer shell 1. After the temperature sensing component 5 is inserted into the temperature sensing port 13, the third sealing component 33 is arranged on the outer shell 1 and is located outside the temperature sensing port 13. The foaming material 4 flows to the inside of the temperature sensing port 13 in a liquid state and is foamed into shape.

[0054] The present invention also provides a third sealing component at the temperature sensing port of the temperature sensing component, which can effectively prevent material from overflowing at the temperature sensing port. Further, the foaming material enters the temperature sensing port for internal foaming molding, which can greatly improve the sealing performance of the temperature sensing port and solve the problem of corrosion of internal components caused by water ingress therein; and effectively improve the thermal insulation effect of the temperature sensing port.

[0055] The temperature sensing port disclosed in the present invention is assembled by a rubber ring buckle and a screw, which tightly fits the end face of the temperature sensing port to prevent overflow. The patch-type temperature sensing package is preferably tightly attached by tin foil adhesive tape, screw locking, etc. to prevent foaming material from entering the temperature sensing probe.

[0056] The temperature sensing port can also use a blind tube probe, which is inserted through a joint. Its structural form can refer to the water outlet form.

[0057] In some embodiments, there are at least two temperature sensing components 5, the temperature sensing ports 13 are arranged in a one-to-one correspondence with the temperature sensing components 5, and the third sealing component 33 is arranged in a one-to-one correspondence with the temperature sensing ports 13. By using more than two temperature sensing components, the temperature of multiple positions of the inner tank can be measured, and the temperature of the hot water inside the water tank assembly can be constantly monitored, which facilitates temperature control.

[0058] In some embodiments, the third sealing component 33 is a rubber ring structure; and / or, the water tank assembly further includes a third fastener 63, and the third fastener 63 fastens the third sealing component 33 to the housing 1. This is a preferred structural form of the third sealing component of the present disclosure, and the rubber structure can effectively play a sealing role and a heat preservation effect, preventing water from entering the interior from the inner wall of the hole and causing corrosion of the internal components; the present disclosure also fastens the third sealing component by setting the third fastener at the temperature sensing port, further improving the anti-overflow effect of the temperature sensing port, and ultimately improving the sealing performance and heat preservation performance of the temperature sensing port.

[0059] In some embodiments, the water tank assembly further includes a heat exchanger 7, the heat exchanger 7 is disposed inside the shell 1, the water inlet 11 is connected to the inner tank 2, and the heat exchanger 7 is connected to a working fluid pipe 71; and a working fluid pipe interface 15 is provided on the shell 1, and the working fluid pipe 71 can pass through the working fluid pipe interface 15 to be connected to the outside of the shell 1;

[0060] The water tank assembly further includes a fourth sealing component 34 disposed outside the working fluid pipe interface 15 , and the foaming material 4 flows to the outer periphery of the working fluid pipe interface 15 to be foamed and formed when in a liquid state.

[0061] The present disclosure also provides a fourth sealing component at the interface of the working fluid pipe, which can effectively prevent the interface of the working fluid pipe from overflowing. The foaming material enters the periphery of the interface of the working fluid pipe for foaming, which can greatly improve the sealing performance of the interface of the working fluid pipe, solve the problem of corrosion of internal components caused by water inflow there, and effectively improve the insulation effect of the interface of the working fluid pipe. Since the working fluid pipe and the joint are usually made of copper / aluminum materials, which are easily corroded when in contact with water, the fourth sealing component and the foaming material of the present disclosure can completely seal and block the external water, preventing the external water from entering the interior.

[0062] The present invention uses a contoured working medium rubber ring to fit the interface of the working medium pipe, and uses screws to assemble the silicone rubber tightly against the curved surface of the shell to eliminate gaps and prevent overflow.

[0063] In some embodiments, the water tank assembly further includes a fourth fastener 64, which fastens the fourth sealing component 34 to the housing 1; and / or the fourth sealing component 34 is a rubber ring structure. The present disclosure also fastens the fourth sealing component by providing a fourth fastener at the interface of the working fluid pipe, further improving the anti-overflow effect of the interface of the working fluid pipe, and ultimately improving the sealing performance and thermal insulation performance of the interface of the working fluid pipe; this is the preferred structural form of the fourth sealing component of the present disclosure, which can effectively play a sealing role and thermal insulation effect through the rubber structure, preventing water from entering the interior from the inner wall of the hole and causing corrosion of internal components.

[0064] In some embodiments, the foaming material 4 is a polyurethane material, and the flowing polyurethane material is poured into between the outer shell 1 and the inner liner 2 and reaches the periphery of the water inlet 11 and the periphery of the water outlet 12 for foaming molding.

[0065] This is the preferred material structure of the foaming material disclosed in the present invention. Due to the characteristic of rigid polyurethane foam with more than 95% closed pores, the foaming material can be bonded to the contact surface to fundamentally prevent water from entering the water tank product from the outside and causing corrosion failure of the inner tank and its components (including heat exchanger components / joint components, etc.).

[0066] Since the polyurethane foam is in a fluid state before reaction, it can penetrate seamlessly and completely fill each assembly gap of the product, thereby achieving overall sealing and fundamentally eliminating contact with the outside world.

[0067] Since polyurethane foam is used for integrated sealing, each component is tightly wrapped in the foam, and the heat dissipation area is greatly reduced, so that the thermal insulation effect can be improved by nearly 10%.

[0068] In some embodiments, a positioning port 16 is further provided on the outer shell 1, and the water tank assembly further includes a fifth sealing component 35, the fifth sealing component 35 is inserted into the outer periphery of the positioning port 16 from the outside of the outer shell 1 toward the inside of the outer shell 1 and abuts against the inner tank 2, and the foaming material 4 flows to the outer periphery of the positioning port 16 in a liquid state and is foamed into shape.

[0069] The present invention also provides a fifth sealing component at the positioning port, which can extend into the positioning port and abut against the inner tank, thereby effectively positioning the inner tank, preventing the inner tank from being excessively deviated inside the water tank and causing the pipe joint to bulge or concave, and effectively preventing overflow. Further, the foaming material enters the periphery of the positioning port for foaming molding, which can greatly improve the sealing performance at the positioning port and solve the problem of corrosion of internal components caused by water ingress there.

[0070] In order to prevent the inner tank from being excessively offset inside the water tank and causing the pipe joint to protrude or be concave (the pipe joint includes other pipe joints such as electric heating joints), the present invention adopts hard foam to half-wrap or fully wrap the pipe mouth structure, and at the same time reserves a foaming material flow channel to facilitate the foaming material to flow to the outer periphery of the pipe joint to form a sealing surface.

[0071] In some embodiments, the water tank assembly further includes a fifth fastener 65, which fastens the fifth sealing component 35 to the housing 1; and / or the fifth sealing component 35 is a hard foam structure (preferably made of polyurethane material). The present disclosure also fastens the fifth sealing component by providing the fifth fastener at the positioning port, further improving the anti-overflow effect of the positioning port, and ultimately improving the sealing performance and thermal insulation performance of the positioning port; this is the preferred structural form of the fifth sealing component of the present disclosure, which can effectively seal through the hard foam structure and effectively position the liner.

[0072] In some embodiments, the fifth sealing component 35 is further provided with a guide hole 351, and the guide hole 351 can guide the liquid foaming material 4 on the outer periphery of the fifth sealing component 35 into the inner periphery of the fifth sealing component 35 and is located at the outer periphery of the positioning port 16. The present disclosure can guide the liquid foaming material on the outer periphery of the fifth sealing component into the inner periphery of the fifth sealing component through the provision of the guide hole, thereby further sealing the outer periphery of the positioning port.

[0073] The present disclosure also provides a water heater, which comprises the water tank assembly described in any of the preceding items.
