Description

Technical Field

[0001] This utility model relates to the technical field of centralized heating heat pump units, and in particular to a novel drainage structure for an indoor unit with a water tank. Background Technology

[0002] Indoor units with water tanks are an important component of centralized heating heat pump units. Their application not only stores hot water to meet hot water demand and achieve energy savings, but also reduces frequent main unit starts, facilitates efficient defrosting, ensures smooth water flow, and prevents system blockage. Thanks to these advantages, indoor units with water tanks are becoming increasingly widely used in the market. Since these units are typically installed indoors and store a large amount of water, leaks can cause damage to indoor items. Therefore, the leak-proof and drainage design of indoor units with water tanks is particularly important.

[0003] Currently, most indoor air conditioners with water tanks on the market only have drainage structures for condensate from components such as the water pump and piping. A small drip tray is placed below these components, and condensate drips onto the tray and drains away through its drain outlet. However, when a leak occurs in the system piping, water sprays out. The existing drip tray has large gaps between itself and the water tank and surrounding sheet metal, making it impossible to catch and drain all the leaking water. Furthermore, when the water tank itself leaks, the leaking water flows into the room through gaps in the sheet metal covering the tank. The existing drip tray cannot protect against leaks at pipe joints inside the tank, nor can it protect against leaks caused by perforations in the tank itself. Utility Model Content

[0004] The main purpose of this utility model is to provide a new type of indoor unit drainage structure with water tank, which can effectively discharge leaked water or condensate water inside the unit along the reserved water receiving tray drain outlet, and avoid the technical problem of water inside the unit leaking to the outside and causing damage to indoor items.

[0005] In order to achieve the above-mentioned utility model objectives, the first aspect of this utility model proposes a novel indoor unit drainage structure with a water tank, including a tank body, a water tank body, a base, and a water receiving tray disposed between the water tank body and the tank body.

[0006] The water receiving tray is arranged around the lower part of the water tank body, and the water receiving tray completely covers the outer surface of the water tank body and fills the gap between the water tank body and the tank body.

[0007] An upper sealing element is provided between the water receiving tray and the water tank body, a side sealing element is provided between the water receiving tray and the tank body, and a lower sealing element is provided between the water tank body and the base;

[0008] The bottom of the water receiving tray is provided with at least one water receiving tray drain port, which is used to direct leaked water or condensate water to the outside of the water tank.

[0009] Furthermore, the water receiving tray is fixed to the water tank body by screws, and / or connected to the tank body by a support plate.

[0010] Furthermore, the upper seal, side seal, and lower seal are made of sponge, rubber, or silicone.

[0011] Furthermore, the height of the water receiving tray is ≥20mm.

[0012] Furthermore, the bottom of the water receiving tray is inclined towards the drain outlet of the water receiving tray.

[0013] Furthermore, the water receiving tray is composed of a detachable first water receiving tray and a second water receiving tray, or is an integral structure. When the water receiving tray is composed of parts, the joint between the first water receiving tray and the second water receiving tray is sealed with sealant or rubber strip.

[0014] Furthermore, the portion of the water tank shell seam located below the water receiving tray is filled with sealant, or the outer surface of the seam is covered with a rubber sealing layer.

[0015] Furthermore, the material of the water receiving tray is a sheet metal stamping part, an injection molded plastic part, a foamed polyethylene integral molded part, or a plastic material part.

[0016] Furthermore, the drain outlet of the water receiving tray is located at the lowest point of the water receiving tray, and the outlet end of the drain outlet of the water receiving tray extends to the outside of the box.

[0018] Beneficial effects:

[0019] 1. This utility model features a water collection tray surrounding the lower part of the water tank, completely enclosing the outer surface of the tank to ensure that leaks from any direction are caught. It employs triple sealing elements (top, side, and bottom) to handle leaks from different directions, preventing leaks due to single-point failure. The bottom of the water collection tray has at least one angled drain outlet, allowing leaked water to flow naturally to the outside without manual intervention. This effectively drains leaked water or condensate from inside the unit through the pre-installed drain outlet, preventing water from leaking out and causing damage to indoor items.

[0031] Reference Figure 1 - Figure 3 An embodiment of this utility model provides a novel drainage structure for an indoor unit with a water tank, including a tank body 1, a water tank body 2, a base 4, and a water receiving tray 3 disposed between the water tank body 2 and the tank body 1;

[0032] The water receiving tray 3 is arranged around the lower part of the water tank body 2, and the water receiving tray 3 completely covers the outer surface of the water tank body 2 and fills the gap between the water tank body 2 and the tank body 1.

[0033] An upper sealing element 8 is provided between the water receiving tray 3 and the water tank body 2, a side sealing element 6 is provided between the water receiving tray 3 and the tank body 1, and a lower sealing element 7 is provided between the water tank body 2 and the base 4.

[0034] The bottom of the water receiving tray 3 is provided with at least one water receiving tray drain port 5, which is used to guide leaked water or condensate water to the outside of the water tank.

[0035] Optionally, the upper seal 8, the side seal 6, and the lower seal 7 may be made of sponge, rubber, or silicone.

[0036] In this embodiment, the water tray 3 is arranged around the lower part of the water tank body 2, completely covering the outer surface of the water tank body 2 and filling the gap between the water tank body 2 and the tank body 1. This structure ensures that leaked water can flow into the water tray 3 regardless of which direction it leaks, preventing water from flowing directly into the indoor environment. The upper seal 8 is located between the water tray 3 and the water tank body 2 to prevent leaked water from flowing under the water tray 3 through the gap between the water tray 3 and the water tank body 2. The material is selected as sponge, rubber, or silicone to ensure good sealing performance. The side seal 6 is located between the water tray 3 and the tank body 1 to prevent leaked water from flowing under the water tray 3 through the gap between the water tray 3 and the tank body 1. It also uses sponge, rubber, or silicone material. The lower seal 7 is located between the water tank body 2 and the base 4 to prevent leaked water from flowing to the outside of the whole machine through the gap between the water tank body 2 and the base 4 when a leak occurs inside the water tank body 2. The bottom of the water tray 3 has at least one water tray drain port 5 to ensure that leaked water can flow naturally to the outside.

[0037] The drip tray 3 is made of sheet metal stamping, injection-molded plastic, foamed polyethylene integral molding, or other plastic materials. These materials have good corrosion resistance and strength, making them suitable for long-term use.

[0038] The water tray 3 and its seals are made of corrosion-resistant materials such as stainless steel, PP plastic, or foamed polyethylene to enhance anti-aging performance. Especially for the selection of seals, considering the potential aging issues caused by prolonged contact with moisture, materials with excellent waterproof properties such as sponge, rubber, or silicone are chosen, but not limited to these three; other sealing methods, such as sealants, can also be used. Simultaneously, chemical adhesives are used to fill and reinforce the joints, further improving the overall sealing effect.

[0039] Optionally, the water tray 3 is fixed to the water tank body 2 with screws, and / or connected to the tank body 1 via a support plate 303. The water tray 3 is made of sheet metal stamping, injection molded plastic, foamed polyethylene integral molding, or other plastic material. The support plate 303 is an L-shaped sheet metal part, with one end fixed to the water tank body 2 and the other end supporting the edge of the water tray 3.

[0040] The water tray 3 can be fixed to the water tank body 2 with screws, or supported and fixed by the support plate 303, or a combination of both. The support plate 303 is an L-shaped sheet metal part. One end of the support plate 303 is fixed to the water tank body 2 or the chassis, and the other end supports the edge of the water tray 3 to ensure the stability of the water tray 3.

[0041] Optionally, the height of the water receiving tray 3 is ≥20mm. The bottom of the water receiving tray 3 is inclined towards the drain outlet 5 of the water receiving tray.

[0042] According to the principles of fluid mechanics, liquids will flow along the lowest path under the influence of gravity. Therefore, the bottom of the water receiving tray 3 is inclined towards the drain outlet 5 to ensure that even a small amount of leaked water can flow smoothly into the drain outlet 5.

[0043] The water receiving tray 3 is composed of a detachable first water receiving tray 301 and a second water receiving tray 302 or is an integral structure. When the water receiving tray 3 is composed of splices, the splice of the first water receiving tray 301 and the second water receiving tray 302 is sealed with sealant or rubber strip.

[0044] When the water receiving tray 3 is assembled from multiple parts, the first water receiving tray 301 and the second water receiving tray 302 are assembled together, and the joint is sealed with sealant or rubber strip to ensure the overall sealing of the water receiving tray 3.

[0045] The portion of the water tank outer shell joint 201 of the water tank body 2 located below the water receiving tray 3 is filled with sealant, or the outer surface of the joint is covered with a rubber sealing layer.

[0046] The portion of the water tank body 2's outer shell seam 201 located below the water receiving tray 3 is filled with sealant or covered with a rubber sealing layer to prevent water leakage from the inside of the water tank body 2 from flowing out into the indoor environment through the seam.

[0047] The drain outlet 5 of the water receiving tray is located at the lowest point of the water receiving tray 3, and the outlet end of the drain outlet 5 extends to the outside of the box body 1.

[0048] The drain outlet 5 of the water receiving tray is located at the lowest point of the water receiving tray 3 and extends to the outside of the tank 1 to ensure that leaked water will not remain in the water receiving tray 3.

[0049] Explanation: When the water tank body 2 or its connecting pipes leak, the leaking water first comes into contact with the water receiving tray 3. Since the water receiving tray 3 completely covers the outer surface of the water tank body 2 and forms multiple layers of protection through the upper seal 8, side seal 6, and lower seal 7, the leaking water is effectively guided into the water receiving tray 3. The bottom of the water receiving tray 3 has one or more water receiving tray drain ports 5. These drain ports 5 are angled to ensure that the leaking water flows naturally to the drain ports 5 under gravity and is ultimately discharged to the outside of the tank body 1 through the drain ports 5.

[0050] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
