Description

Horizontal energy-saving water heater (I)

The present invention relates to a horizontal energy-saving water heater, the purpose of which is to extend the time that the hot water inside the water heater can be kept warm without being heated.

A water heater is a very important device. Its function is to raise the temperature of the water source from normal temperature to the target temperature. The most common application in life is to heat tap water in cold weather to provide users with hot water for bathing.

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 the 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.

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 needs to be solved with great priority.

Generally speaking, based on the convection phenomenon of water, the hotter water in the water heater will be concentrated in the upper half of the entire 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 inner barrel and the top of the outer barrel, and at the same time reduces the distance between the bottom of the inner 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 in the water storage space without heating, and the overall volume does not need to be increased compared to traditional water heaters, which is indeed novel and progressive.

To achieve the above-mentioned purpose and effect, the present invention provides a horizontal energy-saving water heater, which includes: an outer barrel; an inner barrel, which is located in the outer barrel, a first distance length between the top of the inner barrel and the top of the outer barrel, a second distance length between the bottom of the inner barrel and the bottom of the outer barrel, the first distance length is greater than the second distance length, and the inner barrel has a water storage space; an insulation layer, which fills the space between the outer barrel and the inner barrel. a cold water pipe, one end of which is exposed outside the outer barrel, the cold water pipe partially penetrates the inner barrel and the outer 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 penetrates the inner barrel and the outer 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; a control device, which is electrically connected to the heating device.

Furthermore, the material of the thermal insulation layer can be either styrofoam or foam.

Furthermore, the insulation layer can be a vacuum.

Furthermore, the material of the outer barrel and the inner barrel is stainless steel.

Furthermore, the first distance length is more than five times the second distance length.

Furthermore, the positions of the inner barrel and the outer barrel relative to each other make the overall configuration asymmetrical.

To understand the implementation of the present invention in more detail, please refer to the drawings. As shown in the first and second figures, the present invention is a horizontal energy-saving water heater, which includes: an outer barrel 1; an inner barrel 2, which is located in the outer barrel 1, a first distance length A between the top of the inner barrel 2 and the top of the outer barrel 1, a second distance length B between the bottom of the inner barrel 2 and the bottom of the outer barrel 1, the first distance length A is greater than the second distance length B, the inner barrel 2 has a water storage space 21; an insulation layer 3, which is filled with water. Between the outer barrel 1 and the inner barrel 2; a cold water pipe 4, one end of which is exposed outside the outer barrel 1, the cold water pipe 4 partially penetrates the inner barrel 2 and the outer barrel 1, and the other end of the cold water pipe 4 is located inside the inner barrel 2; a hot water pipe 5, one end of which is exposed outside the outer barrel 1, the hot water pipe 5 partially penetrates the inner barrel 2 and the outer barrel 1, and the other end of the hot water pipe 5 is located inside the inner barrel 2; a heating device 6, at least part of which is located inside the inner barrel 2; a control device 7, which is electrically connected to the heating device 6.

In the present invention, the control device 7 is set in the outer barrel 1 as an example. In practice, different setting positions can be used according to different control methods such as manual control and wireless control. The control methods of the control device 7 and the heating device 6 are known technologies and will not be elaborated here.

As shown in the second figure, the material of the thermal insulation layer 3 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).

As shown in the third figure, the insulation layer 3 can be a vacuum.

The above content is followed to further describe the implementation of the present invention. When the present invention is installed, the end of the cold water pipe 4 exposed from the outer barrel 1 is used to connect to the water source, the end of the hot water pipe 5 exposed from the outer barrel 1 is used to connect to the water outlet device (e.g., shower head, faucet), and the control device 7 is connected to the power source (e.g., mains socket). In this embodiment, the cold water pipe 4 and the hot water pipe 5 are two-section type. Generally speaking, based on the convection phenomenon of water, the hotter water in the water heater will be concentrated in the upper half of the entire water storage space 21. Therefore, the upper half of the water storage space 21 of the water heater requires more water than the lower half. In order to improve the heat preservation, the present invention increases the distance between the top of the inner barrel 2 and the top of the outer barrel 1, and reduces the distance between the bottom of the inner barrel 2 and the bottom of the outer barrel 1 (the first distance length A in the figure is greater than the second distance length B), so that the top of the insulation layer 3 will be thicker, and the upper half of the water storage space 21 can achieve better heat preservation effect than the lower half, so that the hot water in the water storage space 21 can be extended without heating. The duration of continuous heat preservation, and the overall volume does not need to be increased compared with the traditional water heater, which is novel and progressive.

The effect is better when the first distance length A is more than five times the second distance length B.

The positions of the inner barrel 2 and the outer barrel 1 make the whole present an asymmetric configuration. Please refer to Figures 4 to 7 for the asymmetric configuration. The center lines L1~L4 in the above figures can clearly understand the so-called asymmetric configuration. The advantage of this configuration is that it can maximize the thermal insulation effect. For example, taking Figure 4 as an example, based on the direction in the figure, the thickness of the right side of the thermal insulation layer 3 is obviously thinner. This configuration is more suitable for the right side against the wall, because the part against the wall itself is not easy to dissipate heat, so only a thinner thickness is needed. The configuration of Figures 5 to 7 is similar. The key is that the thinner part of the thermal insulation layer 3 is suitable for the wall, so that the thermal insulation effect of the side not against the wall can be maximized.

In addition to the above configuration, the inner barrel 2 can also be located at the horizontal center of the outer barrel 1 (distance length C = distance length D) as shown in the second figure.

In addition, looking at Figure 8 and Figure 9, which are experimental data diagrams of the heating times of the conventional water heater and the present invention when not in use, it can be seen that the present invention has a better heat preservation effect under the same time, so the heating times are less, which proves that the present invention can indeed extend the continuous heat preservation time of the hot water in the water storage space when it is not heated compared to the conventional water heater.

The above is only used to explain the preferred embodiment of the present invention, and is not intended to limit the present invention in any form. Therefore, any modification or change made to the present invention under the same spirit of the invention, which is another form that can be implemented and has the same effect, should still be included in the scope of protection intended by the present invention.
