Description

Technical Field

[0001] The utility model belongs to the technical field of heating equipment, and particularly relates to a wall-mounted heating unit and a heating system. Background Art

[0002] A heating unit mainly refers to a device that can raise the temperature of cold water to hot water within a certain period of time through various physical principles. According to different principles, it can be divided into electric heating units, gas heating units, solar heating units, magnetic energy heating units, air energy heating units, and so on.

[0003] Among them, when heating units such as electric heating units and gas heating units are applied in small spaces such as homes and offices, a wall-mounted installation structure is often adopted. However, there are still certain defects in the existing wall-mounted heating units during use: 1. When using electric heating technology to heat water, the electric heating element is in direct contact with the water. Therefore, after long-term use, a layer of scale will form on the surface of the electric heating element, resulting in poor heat exchange efficiency and poor energy utilization rate. At the same time, under the influence of scale, most of the heat is likely to be concentrated on the electric heating element, thereby causing the temperature of the electric heating element to rise, and even seriously, it will directly cause damage to the electric heating element; 2. Most of the existing wall-mounted heating units are directly fixed to the wall through expansion bolts. However, the bolt connection method is not only inconvenient to disassemble when repairing the heating unit, but also easily damages the wall again during secondary installation, and even directly causes damage to the wall. Summary of the Utility Model

[0004] The technical problem solved by the utility model is to provide a new type of wall-mounted heating unit and a heating system, so that scale will not form on the surface of the electric heating element, and it is convenient for maintenance personnel to disassemble and install it.

[0005] In order to solve the above technical problems, on the one hand, the utility model provides a wall-mounted heating unit, which includes a mounting bracket and a wall-mounted box body, one side of the mounting bracket can be fixedly connected to the wall, and the other side of the mounting bracket is detachably connected to the wall-mounted box body through a quick-release mechanism; a heating box is arranged inside the wall-mounted box body, a liquid replenishing port is arranged on the top of the heating box, an electric heating element and a heat-conducting medium are arranged in the inner cavity of the heating box, a liquid inlet and a liquid outlet are arranged on the side of the heating box, a liquid inlet joint is installed on the outer side of the liquid inlet, a liquid outlet joint is installed on the outer side of the liquid outlet, a metal bellows is connected between the inner side of the liquid inlet and the inner side of the liquid outlet, and the bellows is immersed in the heat-conducting medium. In this way, when the utility model is used to heat the water to be heated, the return pipe of the fluid to be heated can be directly connected to the liquid inlet joint, and the input pipe of the fluid to be heated can be connected to the liquid outlet joint. At this time, when the fluid to be heated flows through the heating box in the utility model, the utility model can prevent the fluid to be heated from contacting with the heat-conducting medium and the electric heating element under the isolation of the bellows, thereby preventing scale from forming on the surface of the electric heating element. At the same time, in this process, since the bellows has special internal and external waveforms, the turbulent medium to be heated will continuously wash the internal and external surfaces of the bellows, making it difficult for scale to accumulate on the surface. Even if scale is formed, since the bellows is a flexible element, the curvature of each part of the bellows will continuously change after being affected by the temperature difference during operation. Although the deformation caused by this curvature change is not very large, the linear expansion coefficient of the scale and the metal bellows is very different. Therefore, a large pulling force will be generated between the scale and the surface of the bellows, which is sufficient to make the scale fall off, thereby realizing automatic cleaning and automatic descaling.

[0006] Further, the quick-release mechanism includes an L-shaped hanging block disposed on the hanging seat and an L-shaped card slot disposed on the outer side wall of the wall-mounted box body. The L-shaped hanging block includes a horizontal section and a vertical section. One end of the horizontal section is fixedly connected to the hanging seat, and the lower end of the vertical section is vertically disposed above the end of the horizontal section away from the hanging seat. The L-shaped card slot includes a horizontal groove portion with an opening facing the hanging seat and a vertical groove portion with an opening facing downward. The horizontal groove portion is disposed on the outer side wall of the wall-mounted box body facing the hanging seat, and the height of the horizontal groove portion is greater than the height of the L-shaped hanging block, and the width of the horizontal groove portion is greater than the width of the L-shaped hanging block. The vertical groove portion is disposed at one end of the upper groove wall of the horizontal groove portion away from the opening, and the groove depth of the vertical groove portion is greater than or equal to the height of the vertical section, and the width of the vertical groove portion is greater than the width of the vertical section. When installing the wall-mounted box body at this time, the hanging seat can be first installed on the wall, and then the wall-mounted box body is pushed in the direction close to the hanging seat so that the L-shaped hanging block is located in the L-shaped card slot until the vertical section of the L-shaped hanging block is disposed opposite to the vertical groove portion of the L-shaped card slot. Then, under the action of the self-gravity of the wall-mounted box body, the vertical section of the L-shaped hanging block is inserted into the vertical groove portion of the L-shaped card slot, thereby quickly realizing the installation of the wall-mounted box body. On the contrary, when it is necessary to disassemble the wall-mounted box body, only need to push the wall-mounted box body upward first and then pull it outward to realize the separation between the wall-mounted box body and the hanging seat, without using other tools, and avoiding the damage to the wall caused by secondary installation, achieving the purpose of being convenient for disassembly and assembly.

[0007] Further, the surface of the hanging seat is penetrated with bolt holes and can be fixedly installed on the wall through expansion bolts penetrating through the bolt holes.

[0008] Further, a U-shaped pipe is connected between the liquid outlet end of the corrugated pipe and the liquid outlet. A sewage outlet is disposed at the lower part of the U-shaped pipe. If there are some sediment particles in the corrugated pipe at this time, they can be collected through the U-shaped pipe to avoid them entering the external heat supply circulation pipeline and blocking equipment such as the pump body.

[0009] Further, the sewage outlet is connected to a sewage pipeline, and the output end of the sewage pipeline extends out of the heating box to facilitate maintenance personnel to perform regular sewage treatment on it.

[0010] Further, a liquid level sensor is disposed inside the heating box, and the water level of the heat-conducting medium inside the heating box is monitored in real time through the liquid level sensor to avoid too little heat-conducting medium in the heating box.

[0011] Further, the heat-conducting medium is a superconducting liquid, and it has the characteristics of fast heat conduction speed, high thermal efficiency, no corrosion, non-flammable, etc.

[0012] On the other hand, the present invention also provides a heating system, which includes the above-mentioned wall-mounted heating unit. An external heat supply circulation pipeline is connected between the liquid inlet joint and the liquid outlet joint of the wall-mounted heating unit, and heat supply to an external place is realized through the external heat supply circulation pipeline.

[0013] As can be seen from the above technical solutions, the utility model has the following advantages: 1. When using the utility model to heat water or other fluids to be heated, the fluid to be heated can be isolated by the corrugated pipe, avoiding contact between the fluid to be heated, the heat-conducting medium and the electric heating element, thereby preventing scale from forming on the surface of the electric heating element. At the same time, during this process, due to the special inner and outer waveforms of the corrugated pipe, scale formation on the surface of the corrugated pipe can also be avoided. 2. It can achieve rapid installation and separation between the wall-mounted box body and the hanging seat through the quick-release structure between the hanging seat and the wall-mounted box body, without the need to use other tools, and damage to the wall caused by secondary installation is avoided.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0020] Embodiment 1

[0021] As Figure 1 、 Figure 2As shown in the figure, Embodiment 1 of the present invention provides a wall-mounted heating unit, which includes a hanging seat 12 and a wall-mounted box body 2. Among them, one side of the hanging seat 12 can be fixedly connected to the wall through surface-penetrating bolt holes and expansion bolts, and the other side of the hanging seat 12 is detachably connected to the wall-mounted box body 2 through a quick-release mechanism.

[0022] Specifically, as Figure 2 shown, the quick-release mechanism includes an L-shaped hanging block 14 provided on the hanging seat 12 and an L-shaped card slot 13 provided on the outer side wall of the wall-mounted box body 2. Among them, the L-shaped hanging block 14 includes a horizontal section and a vertical section, and one end of the horizontal section is fixedly connected to the hanging seat 12, and the lower end of the vertical section is vertically arranged above one end of the horizontal section away from the hanging seat 12; the L-shaped card slot 13 includes a horizontal groove portion with an opening facing the hanging seat 12 and a vertical groove portion with an opening facing downwards, and the horizontal groove portion is arranged on the outer side wall of the wall-mounted box body 2 facing the hanging seat 12, and the height of the horizontal groove portion is greater than the overall height of the L-shaped hanging block 14, and the width of the horizontal groove portion is greater than the width of the L-shaped hanging block 14; the vertical groove portion is arranged at one end of the upper groove wall of the horizontal groove portion away from the opening, and the groove depth of the vertical groove portion is greater than or equal to the height of the vertical section, and the width of the vertical groove portion is greater than the width of the vertical section. At this time, when installing the wall-mounted box body 2, the hanging seat 12 can be installed on the wall first, and then the wall-mounted box body 2 is pushed towards the hanging seat 12, so that the L-shaped hanging block 14 is located in the L-shaped card slot 13 until the vertical section of the L-shaped hanging block 14 is arranged opposite to the vertical groove portion of the L-shaped card slot 13, and then under the action of the self-gravity of the wall-mounted box body 2, the vertical section of the L-shaped hanging block 14 is inserted into the vertical groove portion of the L-shaped card slot 13, so as to quickly realize the installation of the wall-mounted box body 2; conversely, when it is necessary to disassemble the wall-mounted box body 2, only need to push the wall-mounted box body 2 upwards first, and then pull the wall-mounted box body 2 outwards, then the separation between the wall-mounted box body 2 and the hanging seat 12 can be realized, without using other tools, and the damage to the wall caused by secondary installation is avoided, achieving the purpose of being convenient for disassembly and assembly.

[0023] A power supply 1, a controller 3 and a heating box 5 are arranged inside the wall-mounted box body 2. A liquid filling port 6 and an exhaust port are arranged at the top of the heating box 5. An electric heating element 7, a heat conduction medium and a liquid level sensor 11 are arranged in the inner cavity of the heating box 5, and the heat conduction medium is preferably a superconducting liquid. A liquid inlet and a liquid outlet are arranged on the side of the heating box 5, and a liquid inlet joint 8 is installed outside the liquid inlet, and a liquid outlet joint 4 is installed outside the liquid outlet. A metal bellows 10 is connected between the inner side of the liquid inlet and the inner side of the liquid outlet. The bellows 10 is immersed in the heat conduction medium and is used to convey the fluid to be heated.

[0024] When heating the fluid waiting for heating using the first embodiment in this way, the return pipeline of the fluid to be heated can be directly connected to the liquid inlet joint 8, and the input pipeline of the fluid to be heated can be connected to the liquid outlet joint 4. At this time, when the fluid to be heated flows through the heating tank 5 in the first embodiment, the first embodiment can, under the isolation of the corrugated pipe 10, prevent the fluid to be heated from contacting the heat-conducting medium and the electric heating element 7, thereby preventing scale from forming on the surface of the electric heating element 7. At the same time, during this process, due to the special inner and outer waveforms of the corrugated pipe 10, the turbulent fluid to be heated will continuously scour the inner and outer surfaces of the corrugated pipe 10, making it difficult for scale to accumulate on the surface. Moreover, even if scaling occurs, since the corrugated pipe 10 is a flexible element, after being affected by the temperature difference during the working process, the curvature of each part of the corrugated pipe 10 will continuously change. Although the deformation caused by this curvature change is not large, the linear expansion coefficients of the scale and the metal corrugated pipe 10 are quite different. Therefore, a relatively large pulling force will be generated between the scale and the surface of the corrugated pipe 10, which is sufficient to make the scale fall off, thus achieving automatic cleaning and automatic descaling.

[0026] As Figure 3 shown, the second embodiment provides a second wall-mounted heating unit. Compared with the first embodiment, the difference is that in the second embodiment, a U-shaped pipe is added between the liquid outlet end of the corrugated pipe and the liquid outlet. A sewage outlet is provided at the lower part of the U-shaped pipe, and the sewage outlet is communicated with a sewage pipeline, and the output end of the sewage pipeline extends outside the heating tank. At this time, if there are some sediment particles in the corrugated pipe, they can be collected and drained through the U-shaped pipe and the sewage pipeline, so as to prevent them from entering the external heat supply circulation pipeline and blocking equipment such as the pump body.

[0027] Embodiment 3

[0028] The third embodiment provides a heating system, which includes the wall-mounted heating unit described in the first embodiment. An external heat supply circulation pipeline 9 is connected between the liquid inlet joint 8 and the liquid outlet joint 4 of the wall-mounted heating unit, and heating of an external place is achieved through the external heat supply circulation pipeline 9.
