Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and specifically relates to a heating tube of an electric water heater and an electric water heater. Background Art

[0002] In scenarios where household water use is concentrated, users will have higher requirements for the water heater's output. To meet these requirements, it is generally recommended that users choose a larger model. However, for large-volume water heaters, on the one hand, their larger size places higher demands on the installation environment, and on the other hand, the increase in volume itself does not necessarily guarantee a significant increase in hot water output. This is because the heating tube structure and heating method of large-volume water heaters are the same as those of small-volume water heaters.

[0003] Therefore, the development of an electric water heater heating tube and an electric water heater not only improves the space utilization of the water heater tank, makes the water temperature in the water heater tank more consistent, but also meets the user's large water demand from the perspective of water heating, which is a technical problem that needs to be solved urgently. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art of increasing the overall volume of the water heater to improve the hot water output capacity of the water heater, which causes the water heater to be inconvenient to install, and the problem of insufficient hot water supply when the user uses hot water in large quantities without increasing the overall volume of the water heater. An electric water heater heating tube and an electric water heater are developed.

[0005] In order to achieve the above-mentioned utility model / design purpose, this utility model adopts the following technical solutions:

[0006] In one aspect, the present invention provides an electric water heater heating tube, comprising:

[0007] The first heating tube includes a first extension section, a second extension section, and a third extension section that are interconnected and extend inside the inner pot. The first extension section extends along the length direction of the inner pot, the second extension section extends along the height direction of the water outlet pipe, and the third extension section extends along the width direction of the inner pot.

[0008] In some embodiments of the present application, the third extension section is provided at the water inlet of the water outlet pipe. Since the third extension section is provided at the water inlet of the water outlet pipe, the third extension section can enhance the water temperature at the water inlet of the water outlet pipe, thereby ensuring that a large amount of warm water can flow from the water outlet pipe.

[0009] In some embodiments of the present application, the third extension section repeatedly bends along the width of the inner pot. This repeated bending of the third extension section along the width of the inner pot enhances water heating across the width of the inner pot. This repeated bending ensures a sufficient amount of heated water.

[0010] In some embodiments of the present application, a second heating tube is further provided in the inner container along the length of the inner container. By providing the second heating tube in addition to the first heating tube in the inner container, the total amount of water heated in the inner container is increased.

[0011] In some embodiments of the present application, the second heating tube extends in the same direction as the first extension; a bend is formed at the end of the second heating tube, and the bend surrounds the first extension. The bend at the end of the second heating tube and the loop surrounding the first extension ensure a high density of heating tubes in the middle of the inner pot, thereby increasing the total amount of water heated within the inner pot.

[0012] In some embodiments of the present application, the first extension section is extended and arranged at the bottom of the inner pot; the second extension section extends from the bottom of the inner pot to the top of the inner pot along the direction of the water outlet pipe; and the third extension section is bent and arranged at the top of the inner pot.

[0013] In some embodiments of the present application, the third extension section is bent to form a Z shape.

[0014] In some embodiments of the present application, the third extension section extends from one side of the water outlet pipe to the other side of the water outlet pipe along the width of the inner tank. The third extension section extends from one side of the water outlet pipe to the other side of the water outlet pipe, repeatedly bending to ensure a uniform increase in temperature around the water outlet pipe.

[0015] On the other hand, the utility model provides an electric water heater, comprising: a water inlet pipe, a water outlet pipe, an inner tank assembly and an electric water heater heating tube as described above; the electric water heater heating tube is extended and arranged in the inner tank assembly.

[0016] In some embodiments of the present application, the inner liner assembly includes a first inner liner and a second inner liner, wherein the first inner liner is arranged above the second inner liner; the water inlet pipe extends into the second inner liner; the water outlet pipe penetrates the second inner liner and extends into the first inner liner; the first heating pipe and the second heating pipe extend into the first inner liner; and the second heating pipe extends into the second inner liner. Since the first inner liner is located above the second inner liner, the water outlet pipe extends into and through the second inner liner and extends into the first inner liner. The water in the first inner liner flows directly out through the water outlet pipe. Therefore, the temperature of the water in the first inner liner is close to the water temperature of the water outlet pipe. Therefore, the first heating pipe and the second heating pipe are arranged in the first inner liner to ensure the temperature of the water in the first inner liner and the amount of warm water.

[0017] Compared with the prior art, the advantages and positive effects of the present invention are:

[0018] By setting a first heating tube, the first heating tube includes a first extension section, a second extension section and a third extension section. The first extension section is extended along the length direction of the inner tank, the second extension section is extended along the direction of the water outlet pipe, and the third extension section is extended along the width direction of the inner tank. The first heating tube extended by the first extension section and the third extension section is provided with heating components in both the length direction and the width direction of the inner tank, thereby uniformly heating the water in the inner tank; by extending the second extension section along the direction of the water outlet pipe, the water temperature around the water outlet pipe is heated, thereby further ensuring the water temperature of the water output along the water outlet pipe, and ensuring the amount of water output at the specified water temperature, thereby meeting the user's large demand for water at the specified temperature.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

For example, they can refer to fixed connections, detachable connections, or integral connections. A person of ordinary skill in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0050] In the description of the present invention, unless otherwise specified, “a plurality of” means two or more.

[0051] Some embodiments of the present application relate to an electric water heater. In scenarios where household water use is concentrated, users often have high expectations for the amount of warm water delivered by the water heater. Currently, some electric water heaters address this demand by increasing the water heater's volume. This approach increases the overall space occupied by the water heater, placing higher demands on the customer's installation space and affecting the aesthetics. Furthermore, it cannot guarantee a continuous output of warm water.

[0052] Therefore, the electric water heater of the present application includes an electric water heater heating tube and an inner tank assembly, wherein the electric water heater heating tube is arranged in the inner tank assembly. Through the design of the electric water heater heating tube, the amount of hot water continuously outputted is increased.

[0053] In some embodiments of the present application, the electric water heater heating tube can be installed in an electric water heater with one inner tank, or can be used in an electric water heater with two inner tanks. There is no limit on the number of inner tanks.

[0054] In some embodiments of the present application, the electric water heater is described by taking a double-tank electric water heater as an example.

[0055] In some embodiments of the present application, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 As shown, the inner liner assembly includes a first inner liner 510 and a second inner liner 520 .

[0056] Here, the first inner container 510 and the second inner container 520 are both extended in the horizontal direction for description.

[0057] Specifically, the first inner liner 510 is located above the second inner liner 520 .

[0058] The water inlet pipe 600 of the electric water heater extends from the bottom of the second inner tank 520 into the second inner tank 520 .

[0059] Specifically, the water inlet pipe 600 extends in a vertical direction and extends from the bottom of the second inner liner 520 into the second inner liner 520 and extends to the upper portion of the internal accommodating cavity of the second inner liner 520 .

[0060] like Figure 3 、 Figure 5 、 Figure 6 、 Figure 8 As shown, the water outlet pipe 200 extends from the bottom of the second inner liner 520 into the second inner liner 520 and passes through the second inner liner 520 into the first inner liner 510, and the water inlet 210 of the water outlet pipe 200 extends into the upper part of the accommodating cavity of the first inner liner 510.

[0061] In some embodiments of the present application, the electric water heater heating tube includes a first heating tube 100. The first heating tube 100 extends from the inner pot opening into the inner pot and extends along the length of the inner pot to the water outlet pipe 200. The first heating tube 100 extending from the water outlet pipe 200 bends and extends in the direction of the water outlet pipe 200 near the water outlet pipe 200. The first heating tube 100 extending to the water inlet 210 of the water outlet pipe 200 extends along the width of the inner pot.

[0062] As a result, the first heating tube 100 increases the amount of hot water along the length and width directions of the inner tank, as well as near the water outlet pipe 200, thereby ensuring continuous output of warm water.

[0063] In some embodiments of the present application, Figure 3 、 Figure 5 、 Figure 6 、 Figure 8 、 Figure 9 、 Figure 10 As shown, the first heating tube 100 includes a first extension section 110, a second extension section 120 and a third extension section 130 which are connected to each other and extend into the inner container.

[0064] The first extension section 110 extends along the length direction of the inner container.

[0065] The second extension section 120 extends along the height direction of the water outlet pipe 200 .

[0066] The third extension section 130 is extended along the width direction of the inner container, thereby expanding the heating range of the water in the inner container.

[0067] Specifically, the second extension section 120 is extended and arranged near the water outlet pipe 200 , thereby increasing the temperature of water near the water outlet pipe 200 and thus increasing the outlet water temperature of the water outlet pipe 200 .

[0068] In order to further increase the water temperature near the water outlet pipe 200 , the third extension section 130 is disposed near the water inlet 210 of the water outlet pipe 200 .

[0069] In some embodiments of the present application, the third extension section 130 is repeatedly bent along the width direction of the inner tank and is centrally arranged at the water inlet 210 of the water outlet pipe 200 .

[0070] Specifically, the third extension section 130 is bent into a Z shape.

[0071] When the third extension section 130 extends and bends along the width direction of the inner pot, the third extension section 130 bends back and forth from one side of the water outlet pipe 200 to the other side of the water outlet pipe 200 along the width direction of the inner pot, thereby increasing the temperature at the water inlet 210 of the water outlet pipe 200.

[0072] Specifically, the first extension section 110 is extended at the bottom of the inner container, the second extension section 120 extends from the bottom of the inner container to the top of the inner container, and the third extension section 130 is extended along the width direction of the top of the inner container.

[0073] Since the third extension section near the water inlet 210 of the water outlet pipe 200 is bent back and forth, the temperature rise rate of the water near the water outlet pipe 200 can be increased, thereby further ensuring the demand for the water outlet pipe 200 to output a large amount of warm water.

[0074] In some embodiments of the present application, in order to increase the overall amount of hot water in the inner pot, a second heating tube 300 may be provided in the inner pot in addition to the first heating tube 100. The second heating tube 300 extends from the inner pot opening into the inner pot and then extends along the length of the inner pot.

[0075] Specifically, the second heating tube 300 is extended along the extension direction of the first extension section 110 .

[0076] The first extension section 110 and the second heating tube 300 both extend from the opening of the inner pot into the inner pot, and then extend along the length direction of the inner pot. During the extension process, the two extend from one side of the water outlet pipe 200 to the other side of the water outlet pipe 200.

[0077] Specifically, such as Figure 9 、 Figure 10 As shown, a bent portion 310 is formed at the end of the second heating tube 300 .

[0078] The bend 310 extends from one side of the water outlet pipe 200 to the other side of the inner container in the longitudinal direction, and then bends back to the initial side, thereby achieving the effect of concentrated heating of the water near the water outlet pipe 200.

[0079] Specifically, the bending portion 310 is disposed around the first extending section 110 .

[0080] In some embodiments of the present application, in order to prevent the third extension section 130 from affecting the water flow rate and water flow speed flowing from the first inner tank 510 through the water inlet 210 to the water outlet pipe 200, the height of the third extension section 130 is set to be lower than the height of the water inlet 210 of the water outlet pipe 200.

[0081] In some embodiments of the present application, Figure 1 、 Figure 2 As shown, a water inlet 710 and a water outlet 720 are provided at the lower portion of the second inner container 520 .

[0082] The lower end of the water inlet pipe 600 is connected to the water inlet 710 , and the water outlet pipe 200 is connected to the water outlet 720 .

[0083] like Figure 1 、 Figure 2 、 Figure 8 As shown, in order to achieve communication between the first inner container 510 and the second inner container 520 and to enable water to flow therebetween, a through portion 730 is provided between the first inner container 510 and the second inner container 520 .

[0084] The first inner container 510 and the second inner container 520 are connected via the through-hole 730 . Water in the first inner container 510 and the water in the second inner container 520 can flow through the through-hole 730 .

[0085] Specifically, there are two through portions 730 .

[0086] The two through-holes 730 communicate between the first inner container 510 and the second inner container 520 .

[0087] The water inlet 710 and the water outlet 720 are both formed below the second inner container 520. The two through-holes 730 are connected above the second inner container 520 and between the first inner container 510.

[0088] The water inlet pipe 600 is connected to the water inlet 710, and the water flows through the water inlet pipe 600 into the water inlet 710 and then flows into the second inner container 520. The water flows through the through portion 730 and enters the first inner container 510 from the second inner container 520.

[0089] The water contained in the first inner container 510 flows out through the water outlet pipe 200 .

[0090] The water outlet pipe 200 is communicated with the water outlet 720 .

[0091] The water outlet pipe 200 extends from the water outlet 720 into the second inner liner 520 , continues to extend upward in the vertical direction, passes through another through portion 730 , extends into the first inner liner 510 , and then extends into the top of the first inner liner 510 in the vertical direction.

[0092] In some embodiments of the present application, since the water outlet pipe 200 extends into the first inner tank 510, the water temperature in the first inner tank 510 directly determines the temperature of the water flowing out of the water outlet pipe 200. Therefore, the first heating tube 100 and the second heating tube 300 are both arranged in the first inner tank 510, thereby increasing the water temperature in the first inner tank 510 and the amount of heated water output.

[0093] A second heating tube 300 may be separately provided in the second inner pot 520 . The second heating tube 300 may heat the water in the second inner pot 520 to a certain initial temperature, so that the water in the second inner pot 520 flows into the first inner pot 510 and is further heated by the first heating tube 100 and the second heating tube 300 provided in the first inner pot 510 .

[0094] By setting a first heating tube 100, the first heating tube 100 includes a first extension section 110, a second extension section 120 and a third extension section 130. The first extension section 110 extends along the length direction of the inner tank, the second extension section 120 extends along the direction of the water outlet pipe, and the third extension section 130 extends along the width direction of the inner tank. The first heating tube 100 extended by the first extension section 110 and the third extension section 130 is provided with heating components in both the length direction and the width direction of the inner tank, thereby uniformly heating the water in the inner tank; by extending the second extension section 120 along the direction of the water outlet pipe 200, the water temperature around the water outlet pipe 200 is heated, thereby further ensuring the water temperature of the water output along the water outlet pipe 200, and ensuring the amount of water output at the specified water temperature, thereby meeting the user's large demand for water at the specified temperature.

[0095] In other embodiments of the present application, a water heater is provided, wherein an inner tank assembly includes an inner tank. Depending on the volume of the inner tank, a first heating tube 100 may be separately provided in the inner tank. Alternatively, depending on the volume of the inner tank, the first heating tube 100 and a second heating tube 300 may be provided in the inner tank.

[0096] Thus, the number of the first heating tube 100 and the second heating tube 300 can be arranged in the inner tank according to the hot water output rate requirement and the volume of the water heater, thereby realizing a series design of the water heater.

[0097] In other embodiments of the present application, an electric water heater has a first inner container 510 and a second inner container 520 disposed vertically. The first inner container 510 and the second inner container 520 are positioned adjacent to each other. In this configuration, the first heating tube 100 extends along the length of the first inner container 510, meaning the first extension section 110 is vertically disposed within the first inner container 510. The third extension section 130 extends horizontally within the first inner container 510. The second extension section also extends along the direction of the water outlet pipe 200.

[0098] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
