Description

Technical Field

[0001] This utility model relates to a novel water heater. Background Technology

[0002] Currently, the most common types of water heaters on the market are storage-type water heaters and gas water heaters. Storage-type water heaters have the function of storing hot water, and in addition to daily showering, they can also provide whole-house heating. Most storage-type water heaters on the market typically have a thermal insulation layer between the inner tank and the outer shell. This insulation layer is made of foam material, which automatically fills the gap between the inner tank and the outer shell. However, this insulation method is not conducive to the later recycling of the water heater. Because the foam adheres firmly to the inner tank and the outer shell, it is usually necessary to break the outer shell to remove the inner tank. Moreover, a large amount of foam material adheres to the surface of the removed inner tank, and this foam material is very difficult to remove.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems. We provide a new type of water heater that improves the insulation structure between the inner tank and the outer shell, so as to facilitate the recycling and reuse of the water heater in the later stage.

[0005] To achieve the above objectives, this utility model provides a novel water heater, comprising an outer shell, an inner tank, a left end cover, and a right end cover. The left and right end covers are respectively connected to the left and right ends of the outer shell. A positioning frame is provided on the inner wall of the left end of the outer shell. The inner tank is placed inside the outer shell, and its left end is fixedly connected to the positioning frame by screws. A heat insulation area is formed between the inner tank and the outer shell. A heat insulation layer is provided in the heat insulation area. The inner and outer sides of the heat insulation layer are tightly attached to the inner tank and the outer shell. A heat insulation cover is provided between the right end cover and the inner tank. The heat insulation cover is connected to the heat insulation layer and covers the right end of the inner tank.

[0006] In one or more embodiments, at least two connecting posts are circumferentially distributed on the left side end of the inner liner, and the connecting posts have threaded holes for screw connection.

[0007] In one or more embodiments, the positioning frame is provided with an annular enclosure, and a positioning groove is formed between the annular enclosure and the inner wall of the outer shell, and at least a portion of the thermal insulation layer extends into the positioning groove.

[0008] In one or more embodiments, both the thermal insulation layer and the thermal insulation cover are made of polyurethane.

[0009] In one or more embodiments, both the left end cap and the right end cap are connected to the outer casing by snap-fit.

[0010] In one or more embodiments, the positioning frame is made of iron and is welded to the outer casing, while the left and right end caps are made of plastic.

[0011] In one or more embodiments, the thickness of the thermal insulation layer is 15mm-30mm.

[0012] Compared with the prior art, the advantages of this utility model are: by improving the structure of the heat insulation layer between the inner tank and the outer shell, the installation of the inner tank is more convenient in the early stage, and the recycling of the inner tank is also more convenient in the later stage. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the water heater in this embodiment. Detailed Implementation

[0014] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0015] Please refer to Figure 1 This application provides a novel water heater, comprising an outer shell 1, an inner tank 2, a left end cover 3, and a right end cover 4. The left end cover 3 and the right end cover 4 are respectively connected to the left and right ends of the outer shell 1. A positioning frame 5 is provided on the inner wall of the left end of the outer shell 1. The inner tank 2 is placed inside the outer shell 1, and its left end is fixedly connected to the positioning frame 5 by screws 6. A heat insulation area is formed between the inner tank 2 and the outer shell 1. A heat insulation layer 7 is provided in the heat insulation area. The inner and outer sides of the heat insulation layer 7 are closely attached to the inner tank 2 and the outer shell 1, and the heat insulation layer provides heat insulation for the inner tank while fixing the inner tank. A heat insulation cover 8 is provided between the right end cover 4 and the inner tank 2. The heat insulation cover 8 is connected to the heat insulation layer 7 and covers the right end of the inner tank 2. The connection between the heat insulation cover and the heat insulation layer further provides heat insulation for the inner tank. When assembling the water heater, first place the inner tank into the outer shell and secure the left side of the inner tank with screws. Then, insert the insulation layer and insulation cover, and finally close the right and left end covers. This structure facilitates initial assembly, saves the waiting time for the foam material to solidify, and allows for non-destructive disassembly of the inner tank and insulation layer when recycling the water heater later.

[0016] At least two connecting posts 10 are distributed circumferentially on the left side end of the inner liner 2. The connecting posts have threaded holes for screws 6 to connect. In this embodiment, three connecting posts are provided. By opening the left end cover and screwing in the screws, the inner liner is fixed on the positioning frame.

[0017] The positioning frame 5 is provided with an annular wall 11, and a positioning groove 12 is formed between the annular wall 11 and the inner wall of the outer shell 1. At least part of the heat insulation layer 7 extends into the positioning groove. When assembling the water heater, the heat insulation layer can be put in first, and then the inner tank can be put in. Since the inner tank is relatively heavy and has a smooth surface, it can be put into the heat insulation layer relatively easily.

[0018] Both the thermal insulation layer 7 and the thermal insulation cover 8 are made of polyurethane. Polyurethane material technology is mature and has good thermal insulation effect.

[0019] Both the left end cover 3 and the right end cover 4 are connected to the outer shell 1 by snap-fit ​​fasteners, which are easy to install and remove. Of course, screws can also be used for fixing; the specific fixing method can be selected according to actual needs.

[0020] The outer shell 1 and the positioning frame 5 are made of iron to ensure the structural strength of the outer shell and the positioning frame. The positioning frame 5 is welded and fixed to the outer shell 1. The left end cover 3 and the right end cover 4 are made of plastic. The plastic left end cover and right end cover have the advantage of being lightweight and can meet the requirements of slight deformation when the buckle is installed and removed.

[0021] The thickness of the thermal insulation layer 7 is 15mm-30mm, preferably 18mm, 23mm, 25mm and 30mm, depending on the volume of the inner liner, and is not limited here.

[0022] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
