The instant water heater solves the problem that the temperature of an existing instant water heater is too high after water supply is cut off.

Description

Technical Field

[0001] The utility model relates to the field of water heaters, in particular to an instant water heater which reduces excessive temperature rise when water is shut down. Background Art

[0002] Water heaters are commonly used electrical appliances in people's daily lives, especially instant water heaters, which can be used immediately and are very convenient to use. The water in the instant water heater needs to be heated quickly, and the water is flowing. In the case of water outage, the hot water discharged from the outlet pipe will not overheat. However, if the water supply is cut off during the use of the instant water heater, the water outlet of the instant water heater will heat up too much after the water supply is restored, which may scald the user. Utility Model Content

[0003] The utility model provides an instant water heater that reduces excessive temperature rise when water is cut off, thereby solving the problem of excessive temperature rise after water is cut off in the existing instant water heaters.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an instant water heater for reducing excessive temperature rise when water is stopped, comprising a plurality of heating chambers arranged side by side, adjacent heating chambers being connected by a plurality of first short tubes, the lower ends of the heating chambers located on the two side edges being respectively connected with a water inlet pipe and a water outlet pipe, a heater being axially inserted into the lower end of the heating chamber, a bypass pipe being arranged on the outer side of the lower end of the heating chamber, the bypass pipe being connected with each heating chamber through a second short tube, and the bypass pipe being arranged so that the cold water in the water inlet pipe can be directly guided to the position of the water outlet pipe, and mixed with the hot water that is overheated at the water outlet pipe, thereby reducing the water temperature of the outlet water and preventing scalding.

[0005] Preferably, a water flow sensing switch is installed on the water inlet pipe, and the water flow sensing switch can sense whether there is water flowing into the water inlet pipe, thereby controlling the start-up of the corresponding heater.

[0006] Preferably, the connecting short tubes between adjacent heating chambers are arranged in an up-and-down staggered manner, so that the water inside the adjacent heating chambers can circulate.

[0007] Preferably, the side of the heating chamber is also connected to a mounting bracket plate to facilitate the integrated installation of a large number of heating chambers.

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

[0009] By setting up a bypass pipe, the cold water in the water inlet pipe can be directly diverted to the outlet pipe, where it can be mixed with the overheated hot water at the 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.

[0013] 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.

[0014] like Figure 1-3 As shown, the utility model provides an instant water heater for reducing excessive temperature rise when water is stopped, comprising a plurality of heating chambers 1 arranged side by side, adjacent heating chambers 1 being connected via a plurality of first short tubes 6, lower ends of the heating chambers 1 located at the edges of both sides are respectively connected with a water inlet pipe 3 and a water outlet pipe 2, a heater 5 is axially inserted into the lower end of the heating chamber 1, a bypass pipe 4 is arranged on the outer side of the lower end of the heating chamber 1, the bypass pipe 4 is connected with each heating chamber 1 via a second short tube 7, and by arranging the bypass pipe 4, cold water in the water inlet pipe 3 can be directly led to the position of the water outlet pipe 2, and mixed with the overheated hot water at the water outlet pipe 2, thereby reducing the outlet water temperature and preventing scalding.

[0015] Specifically, the two ends of the bypass pipe 4 are respectively connected to the lower ends of the heating chambers 1 located at the two side edges, and the side of the bypass pipe 4 is connected to the position corresponding to the heating chamber 1 with a second short pipe 7, so that when the low-temperature water entering the water inlet pipe 3 will enter into each heating chamber 1 along the bypass pipe 4, especially into the heating chamber 1 connected to the water outlet pipe 2, it will be mixed with the high-temperature water to reduce the temperature of the outlet water and prevent scalding.

[0016] In order to automatically control the instant water heater, a water flow sensing switch 9 is installed on the water inlet pipe 3. The water flow sensing switch 9 can sense whether there is water flowing into the water inlet pipe 3, thereby controlling the corresponding heater 5 to start. When the water supply is cut off, the heater 5 will automatically shut down, and when the water supply is restored, the heater 5 will start.

[0017] At the same time, in this embodiment, the connecting short tubes between adjacent heating chambers 1 are staggered up and down, allowing water inside the adjacent heating chambers 1 to circulate. At the same time, the side of the heating chamber 1 is also connected to a mounting bracket plate 8, which facilitates the integrated installation of a large number of heating chambers 1.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] 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.
