To solve the above technical problem, the utility model provides a water heater 100 aims at promoting water heater 100's safety in utilization.

The specific structure of the water heater 100 of the present invention will be described with reference to the following specific embodiments:

as shown in fig. 1 and fig. 2, in an embodiment of the present invention, the water heater 100 includes:

At this time, the steam heat exchanger 10 and the water storage liner 20 are arranged at intervals along the width direction of the shell 70, one end of the water inlet pipe 80a is communicated with the cold water inlet 71 of the shell 70, and the other end of the water inlet pipe 80a is communicated with the liquid inlet 131 of the steam heat exchanger 10; one end of the communicating pipe 80b is communicated with the liquid outlet end 133 of the steam heat exchanger 10, and the other end of the communicating pipe 80b is communicated with the water inlet end 21 of the water storage liner 20; one end of the water outlet pipe 80c is communicated with the water outlet end 23 of the water storage inner container 20, and the other end of the water outlet pipe 80c is communicated with the hot water outlet end 73 of the shell 70. Therefore, the water to be heated can flow into the water heater 100 through the cold water inlet 71, and then flows through the water inlet pipe 80a, the steam heat exchanger 10, the communication pipe 80b, the water storage liner 20 and the water outlet pipe 80c in sequence to become the heated water, and flows out of the water heater 100 through the hot water outlet 73 for the user to use. Not only the flow path is smooth, but also the structure arrangement is reasonable, which is beneficial to the miniaturization of the water heater 100.

It can be understood that in the technical solution of the present embodiment, a water storage liner 20 is added downstream of the steam heat exchanger 10. Therefore, the high-temperature water and/or the high-temperature steam flowing out of the steam heat exchanger 10 can firstly enter the water storage liner 20 to be buffered, and then is output after being buffered by the water storage liner 20.

Therefore, the bottom water body in the water storage liner 20 can absorb the heat of the heating element 40 more favorably, and the temperature of the water body in the water storage liner 20 can be more favorably homogenized. Specifically, the heating body 40 may be formed by winding one heating tube. The heating element 40 can be fixed by flange fixing or screw fastening.

In an embodiment of the present invention of the water heater 100, the water heater 100 further includes a controller, and the heat generating body 40 and the steam heat exchanger 10 are respectively electrically connected to the controller.

In an embodiment of the present invention, the water heater 100 further includes a pressure relief valve disposed on the water inlet path of the steam heat exchanger 10. Specifically, the pressure relief valve is mounted on the cold water intake 71 of the housing 70. It can be understood that the pressure relief valve functions to relieve pressure, so as to prevent the pressure of the flow path system inside the water heater 100 from being too high, and thus, to protect the flow path system inside the water heater 100.

As shown in fig. 1 and 2, in an embodiment of the water heater 100 of the present invention, the steam heat exchanger 10 includes:

a housing 11, a heating chamber 11a is formed in the housing 11;

the heat exchanger 13 is arranged in the heating chamber 11a, one end of the heat exchanger 13 extends out of the shell 11 to form the liquid inlet end 131, and the other end of the heat exchanger 13 extends out of the shell 11 to form the liquid outlet end 133; and the number of the first and second groups,

and the heater 15 is arranged in the heating chamber 11a, and the heater 15 is positioned above the heat exchanger 13.

Specifically, the housing 11 is opened with a water injection port communicated to the heating chamber 11a for introducing a water body into the heating chamber 11a to contact or submerge the heater 15. Accordingly, the housing 11 further includes a sealing member (e.g., a sealing plug, a sealing cover, etc.) provided at the water filling opening for sealing the water filling opening.

It will be understood that the principle of operation of the steam heat exchanger 10 is: the heater 15 heats the water body in the heating chamber 11a, which is in contact with the water body, so that steam is generated after the water is boiled, and the steam rises and fills the whole heating chamber 11 a; as the heater 15 continuously generates heat, steam is continuously generated and saturated, and high-temperature and high-pressure saturated steam is filled in the heating chamber 11a, so that the heat exchanger 13 placed in the saturated steam has a high temperature. At this time, after the water to be heated flows into the water heater 100 from the cold water inlet 71, the water enters the heat exchanger 13 through the water inlet pipe 80a, and the heat of the saturated water vapor is continuously absorbed by the heat exchanger 13 to continuously increase the temperature.

According to the technical scheme of the embodiment, the steam heat exchanger 10 heats the heat exchanger 13 inside through saturated steam generated after the water body inside is heated, so that the water body to be heated flowing through the heat exchanger 13 is heated through the heat exchanger 13 to generate hot water. Moreover, it can be understood that the steam heat exchanger 10 of the embodiment changes the existing manner of storing a large amount of water at a time and directly heating the water by the heater 15, and only heats the heat exchanger 13 by the high-temperature and high-pressure saturated steam, the heating process of the water can be accelerated by using the miniaturized cavity inside the heat exchanger 13, so that the heating time is greatly shortened; meanwhile, the heat exchanger 13 does not need to be electrically contacted and insulated from the heater 15, so that water and electricity are separated, and the potential safety hazard problem caused by electric leakage can be avoided. In addition, the technical scheme of this embodiment has advantages such as power is little, and occupation space is little, and the installation is nimble.

It should be noted that the heat exchanger 13 may be formed by winding a heat exchange pipe, and the heater 15 may be formed by winding a heat pipe. In addition, in order to further shorten the heating time of the water heater 100, the heating pipe and the heat exchange pipe are made of materials with high thermal conductivity. The heater 15 arranged in a winding mode greatly increases the contact area between the heater 15 and the water body in the heating chamber 11a, improves the heating efficiency and shortens the heating time. The heat exchange tube arranged in a winding mode greatly increases the contact area of the heat exchanger 13 and high-temperature and high-pressure saturated steam, improves the heat exchange rate, and can quickly provide hot water for users.

Specifically, as shown in fig. 2, a water filling joint 19 may be provided on the housing 11, a water filling port is opened at the water filling joint 19, a solenoid valve is installed on the water filling joint 19 and is communicated with the water filling port, and the other end of the solenoid valve may be communicated with an external water source. Thus, when the water level is lower than the set value, the electromagnetic valve opens the water filling port, so that the external water source fills water into the heating chamber 11a, and the heater 15 is always submerged in the water; in addition, in order to ensure smooth water injection, the exhaust treatment may be performed on the heating chamber 11a while injecting water. Thus, the user can accurately inject water into the heating chamber 11a through the water level sensor and the electromagnetic valve without manual operation, and humanization and intellectualization of the water heater 100 are improved.

Of course, in an embodiment of the present invention of the water heater 100, the steam heat exchanger 10 further includes a temperature sensor 17 disposed in the heating chamber 11a, and the temperature sensor 17 is electrically connected to the controller. It can be understood that the temperature sensor 17 can detect the temperature of the water in the heating chamber 11a, so as to be used as a basis for controlling the heater 15 of the steam heat exchanger 10 by the controller, so as to realize more accurate control, and further facilitate the water heater 100 to output more accurate water, so as to meet different use requirements of users.

Of course, in an embodiment of the present invention of the water heater 100, the steam heat exchanger 10 further includes an air pressure sensor disposed in the heating chamber 11a, and the air pressure sensor is electrically connected to the controller. It can be understood that the air pressure sensor can detect the pressure of the high-temperature and high-pressure saturated water vapor in the heating chamber 11a, so that the air pressure sensor can be used as a basis for controlling the heater 15 of the steam heat exchanger 10 by the controller to realize more accurate control, and further, the water heater 100 can output water with more accurate temperature to meet different use requirements of users; meanwhile, the pressure protection function can be achieved.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
