Claims

1. A heating device, characterized in that, include: The housing has a front chamber, a heating chamber and a mixing chamber that are connected to each other. The front chamber and the heating chamber are connected through a first port, and the mixing chamber and the heating chamber are connected through a second port. The housing also has an inlet that connects to the front chamber and an outlet that connects to the mixing chamber. A flow guide is disposed in the heating cavity to form a heating flow channel by enclosing the inner wall of the heating cavity; A heating element is disposed within the heating channel and extends along the extension direction of the heating channel.

2. The heating device of claim 1, wherein The pre-heating chamber and the mixing chamber are located above the heating chamber.

3. The heating device of claim 1, wherein, The first through-hole is a strip-shaped hole; And / or, the first outlet is located at the beginning end of the heating channel; And / or, the second outlet is located at the end of the heating channel; And / or, the inlet is located away from the first outlet, and the outlet is located away from the second outlet.

4. The heating device of claim 1, wherein The housing is provided with a first partition plate and a second partition plate. The first partition plate separates the inner cavity of the housing to form the heating cavity and the communicating cavity. The second partition plate separates the communicating cavity to form the front cavity and the mixing cavity. The first passage and the second passage are formed on the first partition plate.

5. The heating device of claim 4, wherein The heating device further includes a cover connected to the heating element. The housing has an opening, and the cover is sealed to the housing and forms the first passage and the second passage with the second partition plate.

6. The heating device of claim 5, wherein The two opposing walls of the heating chamber are each provided with limiting blocks to restrict the movement of the guide component; And / or, the two opposing walls of the heating chamber are provided with guide grooves adapted to the flow guide.

7. The heating device of claim 1, wherein The heating device also includes a temperature sensor, which is installed in the mixing chamber and its water temperature probe is positioned facing the second inlet. And / or, the heating device further includes a temperature control switch disposed in the mixing chamber; And / or, the flow guide is provided with a weight reduction groove.

8. The heating device of any one of claims 1 to 7, wherein, The heating device further includes flow guide partitions, which are arranged in multiple intervals along the heating channel and away from the first inlet, for changing the flow direction of the medium in the heating chamber.

9. The heating device of claim 8, wherein, A flow-through gap is provided between the flow-guiding partition plate and the heating element.

10. The heating device of claim 9, wherein, The flow guide plate includes a first flow guide plate, a second flow guide plate, and a third flow guide plate. The first flow guide plate and the second flow guide plate are respectively disposed on opposite sides of the flow guide member. The third flow guide plate is disposed on the cavity wall of the heating cavity and is located between the first flow guide plate and the second flow guide plate.
