Description

Technical Field

[0001] This utility model relates to the field of heater technology, and in particular to a hot water insulation device and a series-connected hot water machine including the same. Background Technology

[0002] With the increasing global demand for renewable energy, the solar photovoltaic industry has developed rapidly. In the manufacturing process of solar cells, silicon wafers undergo processes such as cleaning, diffusion, annealing, coating, and screen printing. The cleaning process requires the use of various cleaning solutions, and the required temperature of these solutions varies depending on the process, typically necessitating auxiliary heating with a heater.

[0003] For example, patent number CN221944485U discloses a clean-type online heater. This heater heats water through a heating chamber (containing a heating medium). However, during the heating process, the hot water easily loses heat, reducing heating efficiency and affecting production capacity. Furthermore, the heating temperature of this type of heater is relatively high, making it impossible to directly attach ordinary insulation cotton to the coil; otherwise, the insulation cotton would burn. Existing technologies also include solutions that use an insulated box as the heater housing, such as patent number CN201721817629.0. However, the insulated box needs to simultaneously meet the requirements of rigidity and insulation, which increases the manufacturing cost of the insulated box and significantly increases the cost of subsequent maintenance and replacement. Therefore, there is a need to design a water heater with low operating costs and reduced heat loss. Utility Model Content

[0004] To address the technical problems of heat loss and high manufacturing cost in existing medicine liquid heaters, this utility model provides a hot water insulation device and a series-connected hot water heater containing the device to solve the above problems.

[0005] This utility model proposes a hot water insulation device, including a box and a heating coil located inside the box. The heating coil includes a columnar main body and liquid inlet and liquid outlet located at both ends of the columnar main body. The box has through holes for the liquid inlet and liquid outlet to extend out. The outer periphery of the columnar main body is covered with an annular heat insulation plate. Lateral heat insulation cotton is attached to the outside of the annular heat insulation plate. The top height of the annular heat insulation plate is higher than the height of the columnar main body. A top heat insulation cotton connected to the annular heat insulation plate is located above the columnar main body. The lateral heat insulation cotton, the top heat insulation cotton, and the bottom of the box form an insulation cavity.

[0006] In an optional embodiment of this utility model, the annular heat insulation plate is formed by splicing together mica sheets.

[0007] In an optional embodiment of this utility model, the annular heat insulation plate is fixed to the bottom of the box body, and a pad is provided at the bottom of the box body and inside the annular heat insulation plate. Bottom insulation cotton is fixed on the pad, and the bottom insulation cotton is separated from the columnar main body.

[0008] In an optional embodiment of this utility model, the lateral insulation cotton is rolled and wrapped around the annular heat insulation plate, and the lateral insulation cotton is fixed by clamps.

[0009] In an optional embodiment of this utility model, the mica sheet has a planar structure, and four mica sheets form the four side plates of the annular heat insulation plate.

[0010] In an optional embodiment of this utility model, the annular heat insulation plate is arranged in close contact with the columnar main body.

[0011] In an optional embodiment of this utility model, the thickness of the annular heat insulation plate is 2 to 4 cm.

[0012] This utility model also proposes a series-connected water heater, including a cabinet, electrical components, a control panel, and multiple hot water insulation devices as described above, with the heating coils of the multiple hot water insulation devices connected in series.

[0013] In an optional embodiment of this utility model, the cabinet is divided into a heating chamber and a control chamber along the front-to-back direction. The control panel is located in the control chamber, the hot water insulation device is located in the heating chamber, and the heating chamber is provided with multiple platforms, with electrical components located on the uppermost platform.

[0014] In an optional embodiment of this utility model, the hot water insulation device is arranged in an even number of layers in the heating chamber. The liquid inlet and liquid outlet on each cabinet are located on the same panel of the cabinet. The hot water insulation devices on the same layer are connected in series and then connected to the hot water insulation devices on the adjacent platform so that the inlet and outlet on the cabinet are located on the same side of the cabinet.

[0015] The beneficial effects of this utility model are:

[0016] (1) The present invention designs the heating coil as a regular columnar structure, which makes it convenient to cover the outer ring heat insulation plate. The heat is isolated by the ring heat insulation plate. The side insulation cotton is then attached to the outside of the ring heat insulation plate to avoid contact between the side insulation cotton and the heating coil. The top insulation cotton is supported by the top of the ring heat insulation plate to separate it from the heating coil. Thus, the heat preservation effect is achieved and the insulation cotton is protected.

[0017] (2) The materials used in this utility model are simple. By setting insulation materials inside the box, the insulation requirements of the box are reduced, thereby reducing the manufacturing cost of the entire hot water insulation device.

[0018] (3) Each hot water insulation device in this utility model can be designed in a small size. High temperature heating can be achieved by connecting multiple hot water insulation devices in series. The heating effect is good and maintenance is convenient.

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] Example 1

[0029] like Figures 1-3As shown, a hot water insulation device includes a housing 1 and a heating coil 2 located inside the housing 1. The heating coil 2 includes a columnar main body 201 and liquid inlet 202 and liquid outlet 203 located at both ends of the columnar main body 201. The housing 1 has through holes 101 for the liquid inlet 202 and liquid outlet 203 to extend out. The outer periphery of the columnar main body 201 is covered with an annular heat insulation plate 3. Lateral heat insulation cotton 4 is attached to the outside of the annular heat insulation plate 3. The top height of the annular heat insulation plate 3 is higher than the height of the columnar main body 201. A top heat insulation cotton 5 connected to the annular heat insulation plate 3 is located above the columnar main body 201. The lateral heat insulation cotton 4, the top heat insulation cotton 5, and the bottom of the housing 1 form an insulation cavity 6.

[0030] This invention designs the heating coil 2 as a regular columnar structure, facilitating the external covering with an annular heat insulation plate 3. The annular heat insulation plate 3 is made of a high-temperature resistant material, such as mica. The annular heat insulation plate 3 is fixed to the housing 1, and its outer side is covered with lateral insulation cotton 4. Since heat easily dissipates to the surroundings and upwards, a top insulation cotton 5 is installed above the heating coil 2. The top insulation cotton 5 is supported by the annular heat insulation plate 3 to prevent it from contacting the heating coil 2.

[0031] Normally, the insulation cotton does not come into contact with the heating coil 2, which can prevent it from being burned to a certain extent. However, the insulation cotton itself is not rigid enough, so it needs to be supported by the annular heat insulation plate 3. In the outer peripheral direction, the side insulation cotton 4 has a large surface area facing the heating coil 2. The high-temperature resistant annular heat insulation plate 3 can further prevent the side insulation cotton 4 from being burned. The top insulation cotton 5 has a very small area facing the heating coil 2, so it can be separated by air.

[0032] It should be noted that since the heating coil 2 has an inlet 202 and an outlet 203 extending out of the housing 1, the annular heat insulation plate 3 also needs to be provided with a corresponding hole structure, that is, the heat insulation cavity 6 is not a completely sealed structure.

[0033] The annular heat insulation plate 3 can be formed by splicing mica sheets. Mica sheets are usually planar structures. In this embodiment, the annular heat insulation plate 3 consists of four mica sheets forming four side panels. The thickness of the annular heat insulation plate 3 is preferably 2 to 4 cm.

[0034] To ensure the stability of the annular heat insulation plate 3, the annular heat insulation plate 3 and the columnar main body 201 are preferably arranged in close contact, in which case the columnar main body 201 can provide a certain support for the annular heat insulation plate 3.

[0035] The lateral insulation cotton 4 can be wrapped around the annular heat insulation plate 3 by rolling, and finally fixed by clamps 7. Specifically, after two clamps 7 are wrapped around the lateral insulation cotton 4, the two clamps 7 are tightened with bolts.

[0036] Example 2

[0037] Based on the above embodiment, a pad 8 is provided at the bottom of the box 1 and inside the annular heat insulation plate 3. Bottom insulation cotton 9 is fixed on the pad 8, and the bottom insulation cotton 9 is separately set from the columnar main body 201. The function of the pad 8 is to raise the bottom insulation cotton 9, reduce the space of the heat insulation cavity 6, improve the heat insulation effect, and at the same time prevent the bottom of the box 1 from overheating.

[0038] Example 3

[0039] A series-connected water heater includes a cabinet 10, electrical components 11, a control panel 12, and multiple hot water insulation devices 13 as described above, wherein the heating coils 2 of the multiple hot water insulation devices 13 are connected in series.

[0040] Multiple hot water insulation devices 13 connected in series can gradually raise the temperature of the heated medium, thereby reducing the size of each hot water insulation device 13, facilitating the arrangement of the insulation structure inside each hot water insulation device 13, and allowing for independent removal and replacement when individual hot water insulation devices 13 malfunction, resulting in low maintenance costs.

[0041] In further design, such as Figure 3 and Figure 4 As shown, the cabinet 10 is divided into a heating chamber 14 and a control chamber 15 along the front-to-back direction. The control panel 12 is located in the control chamber 15, and the hot water insulation device 13 is located in the heating chamber 14. The heating chamber 14 is equipped with multiple platforms 16, and the electrical components 11 are located on the top platform 16. The heating chamber 14 is separated from the control chamber 15 and adjacent platforms 16 by partitions, so that the components do not interfere with each other. The electrical components 11 are located on the top layer to prevent damage to the electrical components 11 caused by leakage from the cabinet 1.

[0042] Considering the pipeline layout, the hot water insulation device 13 is preferably arranged in an even number of layers within the heating chamber 14. The inlet 202 and outlet 203 on each cabinet 1 are located on the same panel of the cabinet 1. The hot water insulation devices 13 on the same layer are connected in series and then connected to the hot water insulation devices 13 on the adjacent platform 16, so that the inlet 17 and outlet 18 on the cabinet 10 are located on the same side of the cabinet 10. For example... Figure 4 As shown, the platform 16 on which the hot water insulation device 13 is placed has an inlet 17 of two cabinets 10. The inlet 17 connects the hot water insulation device 13 from the right side of the first layer, and then connects the hot water insulation devices 13 in sequence between the hot water insulation devices 13 on the first layer platform 16. Then, the hot water insulation device 13 on the left side of the second layer platform 16 is connected to the hot water insulation device 13 on the right side, and finally the hot water is discharged from the outlet 18 of the second layer cabinet 10.

[0043] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0045] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature and another element or feature illustrated in the figures. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0046] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
