Description

Technical Field

[0001] The invention relates to a horizontal energy-saving water heater, which aims to prolong the time for which hot water inside the water heater is kept warm without being heated. Background Art

[0002] A water heater is a very important device. Its function is to raise the temperature of water from room temperature to the target temperature. A common application in life is to heat tap water in colder weather to supply users with hot water for bathing.

[0003] Water heaters are generally classified into gas-fired and electric-heated types in terms of heating methods. Gas-fired water heaters have many restrictions on installation locations because the exhaust gas produced during combustion can be fatal, such as carbon monoxide. Therefore, they must be installed in areas where exhaust gas can be discharged, which is not easy for many residents, so they choose to use electric-heated water heaters. However, compared to gas-fired water heaters, although electric-heated water heaters do not produce fatal exhaust gas during use, the common basic type has a power consumption of more than 4kw, which has the disadvantage of high power consumption.

[0004] In view of the above content, it can be known that how to develop an electric water heater that improves the efficiency of hot water supply to save electricity expenses and energy consumption is a problem that is of great priority to be solved. Summary of the invention

[0005] The main technical problem to be solved by the present invention is to overcome the above-mentioned defects of the prior art and provide a horizontal energy-saving water heater. Generally speaking, based on the convection phenomenon of water, the hotter water in the water storage of the water heater will be concentrated in the upper half of the overall water storage space. Therefore, the upper half of the water storage space of the water heater requires more insulation than the lower half. Therefore, the present invention increases the distance between the top of the middle barrel and the top of the outer barrel, and at the same time reduces the distance between the bottom of the middle barrel and the bottom of the outer barrel. In this way, the upper half of the water storage space can achieve better insulation effect than the lower half. This can indeed extend the continuous insulation time of the hot water inside the water storage space when it is not heated, and the overall volume does not need to be increased compared to traditional water heaters, which is truly novel and progressive.

[0006] The technical solution adopted by the present invention to solve its technical problem is:

[0007] A horizontal energy-saving water heater comprises: an outer barrel; a middle barrel located inside the outer barrel, a distance length A between the top of the middle barrel and the top of the outer barrel, a distance length B between the bottom of the middle barrel and the bottom of the outer barrel, and the distance length A is greater than the distance length B; an inner barrel located inside the middle barrel, the inner barrel having a water storage space; a first heat-insulating layer located between the outer barrel and the middle barrel; a second heat-insulating layer located between the middle barrel and the inner barrel The outer barrel is provided with a plurality of heating elements, wherein the heating elements are provided between the outer barrel and the middle barrel; a cold water pipe, one end of which is exposed outside the outer barrel, the cold water pipe partially passes through the outer barrel, the middle barrel and the inner barrel, and the other end of the cold water pipe is located inside the inner barrel; a hot water pipe, one end of which is exposed outside the outer barrel, the hot water pipe partially passes through the outer barrel, the middle barrel and the inner barrel, and the other end of the hot water pipe is located inside the inner barrel; a heating device, at least part of which is located inside the inner barrel; and a control device, which is electrically connected to the heating device.

[0008] Furthermore, the material of the first thermal insulation layer and the second thermal insulation layer is one of styrofoam and foam material.

[0009] Furthermore, the material of the first thermal insulation layer and the second thermal insulation layer is vacuum.

[0010] Furthermore, the outer barrel, the middle barrel and the inner barrel are made of tinplate.

[0011] Furthermore, the distance length A is more than five times the distance length B.

[0012] Furthermore, there is a distance length C between the top of the middle barrel and the top of the inner barrel, and a distance length D between the bottom of the middle barrel and the bottom of the inner barrel, and the distance length C is greater than the distance length D.

[0013] Furthermore, the positions of the inner barrel, the middle barrel and the outer barrel relative to each other make the whole present an asymmetric configuration.

[0014] The beneficial effect of the present invention is that the present invention increases the distance between the top of the middle barrel and the top of the outer barrel, and at the same time reduces the distance between the bottom of the middle barrel and the bottom of the outer barrel, so that the upper half of the water storage space can achieve better insulation effect than the lower half, which can indeed extend the time for the hot water inside the water storage space to be kept warm without heating, and the overall volume does not need to be increased compared with traditional water heaters, which is truly novel and progressive.

[0051] To understand the embodiments of the present invention in more detail, please refer to the accompanying drawings. Figure 1 , Figure 2 The present invention is a horizontal energy-saving water heater, comprising: an outer barrel 1; a middle barrel 2, which is located in the outer barrel 1, a distance length A is between the top of the middle barrel 2 and the top of the outer barrel 1, a distance length B is between the bottom of the middle barrel 2 and the bottom of the outer barrel 1, and the distance length A is greater than the distance length B; an inner barrel 3, which is located in the middle barrel 2, and the inner barrel 3 has a water storage space 31; a first insulation layer 4, which is located between the outer barrel 1 and the middle barrel 2; a second insulation layer 5, which is located between the middle barrel 2 and the outer barrel 1 The inner barrel 3 is provided with a cold water pipe 6, one end of which is exposed outside the outer barrel 1, and the cold water pipe 6 partially passes through the outer barrel 1, the middle barrel 2, and the inner barrel 3, and the other end of the cold water pipe 6 is located inside the inner barrel 3; a hot water pipe 7, one end of which is exposed outside the outer barrel 1, and the hot water pipe 7 partially passes through the outer barrel 1, the middle barrel 2, and the inner barrel 3, and the other end of the hot water pipe 7 is located inside the inner barrel 3; a heating device 8, which is at least partially located inside the inner barrel 3; a control device 9, which is electrically connected to the heating device 8.

[0052] In the present invention, the control device 9 is set in the outer barrel 1 as an example. In fact, it can have different setting positions according to different control methods such as manual control and wireless control. The control method of the control device 9 and the heating device 8 is the existing technology and will not be described in detail here.

[0053] like Figure 2 As shown, the material of the first insulation layer 4 and the second insulation layer 5 can be one of styrofoam and foam material, and the foam material can be polystyrene (EPS), polyurethane (PU), polyethylene (PE), polyvinyl chloride (PVC), polystyrene-butadiene rubber (EPP), polyoxymethylene foam (PF), and polypropylene (PP).

[0054] like Figure 3 As shown, the first thermal insulation layer 4 and the second thermal insulation layer 5 can be vacuum.

[0055] The outer barrel 1, the middle barrel 2 and the inner barrel 3 are made of tin.

[0056] The above content is followed to further describe the implementation mode of the present invention. When the present invention is installed, the end of the cold water pipe 6 exposed from the outer barrel 1 is used to connect to the water source, the end of the hot water pipe 7 exposed from the outer barrel 1 is used to connect to the water outlet device (for example, a shower head, a faucet), and the control device 9 is connected to the power supply (for example, a mains socket). In this embodiment, the cold water pipe 6 and the hot water pipe 7 are taken as two-section types. Generally speaking, based on the convection phenomenon of water, the hotter water in the water storage of the water heater will be concentrated in the upper half of the overall water storage space 31. Therefore, the upper half of the water storage space 31 of the water heater requires more insulation than the lower half. For this reason, the present invention is as follows. Figure 2 As shown, the distance between the top of the middle barrel 2 and the top of the outer barrel 1 is increased, and at the same time the distance between the bottom of the middle barrel 2 and the bottom of the outer barrel 1 is reduced (the distance length A in the figure is greater than the distance length B). In this way, the top part of the first insulation layer 4 will be thicker, and the upper half of the water storage space 31 can achieve better insulation effect than the lower half. In this way, the hot water in the water storage space 31 can be kept warm for a longer time without being heated, and the overall volume does not need to be increased compared with traditional water heaters. It is indeed novel and progressive.

[0057] When the distance length A is more than five times the distance length B, the effect is better.

[0058] In addition, Figure 4 As shown, there is a distance length C between the top of the middle barrel 2 and the top of the inner barrel 3, and a distance length D between the bottom of the middle barrel 2 and the bottom of the inner barrel 3. The distance length C is greater than the distance length D. In this configuration, in addition to the first insulation layer 4, the top part of the second insulation layer 5 will also be thicker to further enhance the insulation effect of the upper half of the water storage space 31.

[0059] The positions of the inner barrel 3, the middle barrel 2 and the outer barrel 1 make the overall configuration asymmetrical. Figures 5 to 8 The so-called asymmetric configuration can be clearly understood from the center lines L1 to L4 in the above-mentioned figures. The advantage of this configuration is that it can maximize the thermal insulation effect. Figure 5 For example, based on the direction in the attached figure, the thickness of the right side of the first insulation layer 4 and the second insulation layer 5 is obviously thinner. This configuration is more suitable for the setting on the right side against the wall, because the part against the wall itself is not easy to dissipate heat, so only a thin thickness is required. Figures 6 to 8The configuration is similar, the key is that the thinner parts of the first insulation layer 4 and the second insulation layer 5 are suitable for being close to the wall, so that the insulation effect of the side not close to the wall can be maximized.

[0060] In addition to the above configuration, it can also be Figure 2 As presented, the inner barrel 3 is located at the center of the middle barrel 2 (distance length E = distance length F, distance length G = distance length H), and the middle barrel 2 is located at the horizontal center of the outer barrel 1 (distance length I = distance length J).

[0061] Also watch Fig. 9 and Fig.10 This is an experimental data chart of the number of heating times of the existing water heater and the present invention when not in use. It can be seen that under the same time, the present invention has a better insulation effect, so the number of heating times is less. This proves that compared with the existing water heater, the present invention can indeed extend the continuous insulation time of the hot water inside the water storage space when it is not heated.

[0062] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
