Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.
[0034] The following is combined with Figures 1 - 5The utility model is described as a heating device, which comprises a housing 1 , a spiral heating device 2 and a spiral medium channel 3 .
[0035] like Figure 1 and Figure 2 As shown, a through first air duct 11 is formed inside the shell 1; the spiral heating device 2 is arranged inside the shell 1, and the spiral heating device 2 is arranged close to the first air duct 11; the spiral medium channel 3 is arranged inside the shell 1 and is thermally coupled with the spiral heating device 2. The spiral medium channel 3 is used to infuse fluid medium, and under the heating action of the spiral heating device 2, the heat medium or hot steam is discharged.
[0036] Specifically, the spiral heating device 2 can adopt a spiral heating wire, which can be in the form of an electric heating wire. After power is turned on, the electric heating wire releases heat. The first air duct 11 is a hollow structure inside the shell 1. Cold air can be introduced through the hollow structure, and hot air is formed after being heated by the electric heating wire. The medium poured into the spiral medium channel 3 can be water. After being heated by the electric heating wire, the cold water becomes hot water; by reducing the amount of water added and increasing the power of the electric heating wire, the cold water becomes steam. The thermal coupling method between the spiral heating device 2 and the spiral medium channel 3 can be contact or non-contact, but the contact heat transfer between the spiral heating device 2 and the spiral medium channel 3 can achieve a higher thermal conductivity.
[0037] The heating device of the utility model has three working modes: hot air mode, hot water mode and steam mode.
[0038] In the hot air mode, cold air is introduced through the first air duct 11 inside the housing 1, and the spiral heating device 2 is started. After being heated by the spiral heating device 2, the cold air in the first air duct 11 is heated to hot air.
[0039] In the hot water / steam mode, cold water is introduced into the spiral medium channel 3, and the spiral heating device 2 is started. After being heated by the spiral heating device 2, the cold water in the spiral medium channel 3 is heated by thermal coupling (preferably by heat conduction), and hot water or steam is output according to the flow rate of the cold water and the power of the electric heating wire. It can be understood that if the flow rate of the cold water is large and the power of the electric heating wire is small, the spiral medium channel 3 outputs hot water; if the flow rate of the cold water is small and the power of the electric heating wire is large, the spiral medium channel 3 outputs steam.
[0040] In summary, the heating device of the utility model integrates three working modes of hot air mode, hot water mode and steam mode, and the high-temperature steam sterilization is more thorough; and due to the spiral structures of the spiral heating device 2 and the spiral medium channel 3, and the first air duct 11 formed inside the shell 1, it has the advantages of saving space and reducing costs.
[0041] The utility model provides a heating device, which includes: a shell 1, a spiral heating device 2 and a spiral medium channel 3; a through first air channel 11 is formed inside the shell 1; the spiral heating device 2 is arranged inside the shell 1, and the spiral heating device 2 is arranged close to the first air channel 11; the spiral medium channel 3 is arranged inside the shell 1 and is thermally coupled with the spiral heating device 2, and the spiral medium channel 3 is used to infuse fluid medium, and under the heating action of the spiral heating device 2, the heat medium or hot steam is guided out. The utility model provides a heating device, which is a multi-purpose machine, and integrates three working modes of hot air mode, hot water mode and steam mode; sterilization is more thorough in the steam mode; due to the spiral structure of the spiral heating device 2 and the spiral medium channel 3 and the structural arrangement matched with the first air channel 11 inside the shell 1, it has the advantages of saving space and reducing costs.
[0042] In one embodiment of the present invention, the spiral heating device 2 and the spiral medium channel 3 are both multi-layer spiral structures, and the spiral medium channel 3 and the spiral medium channel 3 are interlaced and embedded in the gap between each other's multi-layer spiral structures.

In order to improve the heating efficiency of the fluid medium and ensure the uniform heating effect, the spiral heating device 2 and the spiral medium channel 3 in this embodiment are interlaced and embedded in the gap between two adjacent layers of each other's multi-layer spiral structure. Both sides of the spiral medium channel 3 can be heated by the spiral heating device 2, which improves the heating efficiency of the electric heating wire and ensures the uniform heating effect of the cold water.
[0043] In one embodiment of the present invention, the spiral heating device 2 and the spiral medium channel 3 are at least partially in contact, so that the spiral heating device 2 and the spiral medium channel 3 are heat-conducted. In this embodiment, the heat conduction between the spiral heating device 2 and the spiral medium channel 3 is achieved through the contact between the spiral heating device 2 and the spiral medium channel 3, and the heat conduction method of contact heat conduction improves the heat conduction efficiency compared to the heat conduction method of non-contact heat conduction, thereby increasing the temperature of the fluid medium.

Through the heat conduction rib plates 4, on the one hand, the contact area with air is increased, improving the heat conduction efficiency; on the other hand, since the heat conduction rib plates 4 have a guiding effect on the air flow and disturb the air flow, the heat transfer efficiency is further improved, making the hot air temperature increase.

[0047] In one embodiment of the present utility model, the housing 1 is formed with a third positioning hole 14 and a fourth positioning hole 15. The third positioning hole 14 is used to position one end of the spiral medium channel 3, and the fourth positioning hole 15 is used to position the other end of the spiral medium channel 3. In this embodiment, the spiral medium channel 3 is fixed on the housing 1, one end is fixed through the third positioning hole 14 at the upper end of the housing 1, and the other end is fixed through the fourth positioning hole 15 at the upper end of the housing 1, facilitating the installation and positioning of the spiral medium channel 3.
[0048] In one embodiment of the present utility model, the housing 1 is a heat-conducting housing 1, and a second air duct (not shown in the figure) is formed on the outside of the heat-conducting housing 1. In this embodiment, the housing 1 is made of a heat-conducting material and is a heat-conducting housing 1.

The cold air outside can also be heated to form hot air through the heat-conducting housing 1.
