Description

Technical Field

[0001] The utility model relates to the field of water heaters, in particular to a water heater heating device that prevents excessive temperature rise when water is cut off. Background Art

[0002] Water heaters are commonly used electrical appliances in people's daily lives. A heating device needs to be installed in the water heater, which mainly uses the heating components to quickly heat the water flowing through the coil. Moreover, the water is flowing. When there is no water outage, the hot water discharged from the outlet pipe will not overheat. However, if there is a water outage during the use of the water heater, the water outlet will heat up too much after the water outage is restored, which may scald the user. Utility Model Content

[0003] The utility model provides a water heater heating device that prevents excessive temperature rise when water is cut off, solving the problem of excessive temperature rise after water is cut off in the existing water heater.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a water heater heating device that prevents excessive temperature rise when the water supply is cut off, comprising a heating body, the heating body having a water inlet pipe and a water outlet pipe, characterized in that a cooling pipe is arranged between the water inlet pipe and the water outlet pipe, and the cooling pipe is at least partially located in the heating body or at least partially in contact with the heating body.

[0005] Preferably, the cooling pipe comprises a transverse portion and bent connecting portions arranged at both ends of the transverse portion, and the transverse portion is located inside the heating body or in contact with the heating body.

[0006] Preferably, a positioning seat is transversely arranged on the outer side wall of the heating body, and the transverse portion is embedded in a groove on the positioning seat.

[0007] Preferably, the heating body comprises an outer shell and a heating coil arranged inside the outer shell, and a heating component is arranged inside the heating coil.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] By setting up a cooling pipe, the cold water in the water inlet pipe can be directly diverted to the water outlet pipe, where it can be mixed with the overheated hot water at the water outlet pipe, thereby lowering the outlet water temperature, preventing scalding, and solving the problem of excessive temperature rise when the water supply is cut off, thereby avoiding scalding users due to excessive temperature rise when the water supply is cut off.

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0015] like Figure 1-4 As shown, the utility model provides a water heater heating device for preventing excessive temperature rise during water outage, including a heating body 4, the heating body 4 having a water inlet pipe 1 and a water outlet pipe 2, a cooling pipe 3 is arranged between the water inlet pipe 1 and the water outlet pipe 2, and the cooling pipe 3 is at least partially located in the heating body 4 or at least partially in contact with the heating body 4.

[0016] Specifically, the cooling pipe 3 can directly guide the cold water in the water inlet pipe to the position of the water outlet pipe, so that the water temperature of the water outlet pipe can be reduced. The cooling pipe 3 is partially located in the heating body 4 or at least partially in contact with the heating body 4. The heat generated by the heating body 4 can be used to preheat the cold water in the cooling pipe 3. The heat generated by the heating body 4 can be reasonably used to ensure that the cold water entering the water outlet pipe 2 is not too cold, which will cause a relatively large change in the temperature of the outlet water.

[0017] The heating body 4 includes an outer shell and a heating coil 6 arranged inside the outer shell. A heating component 5 is arranged inside the heating coil 6. The heating component 5 can be a burner or an electric heating component.

[0018] In this embodiment, the cooling tube 3 includes a transverse portion 31 and a bent connection portion 32 arranged at both ends of the transverse portion 31. The transverse portion 31 is located in the heating body 4 or in contact with the heating body 4. The bent connection portion 32 can support the transverse portion 31 so that the transverse portion 31 can be located in the heating body 4 or in contact with the heating body 4.

[0019] In order to position the transverse portion 31 and effectively utilize the temperature of the heating body 4, a positioning seat 7 is transversely arranged on the outer wall of the heating body 4, and the transverse portion 31 is embedded in the groove on the positioning seat 7, with a relatively large contact area.

[0020] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0021] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0022] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" 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 the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
