Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 1 and 2, the heat generating device of the present embodiment includes: a housing 10 and a heat generating component 20. Wherein the housing 10 has an air duct 1. The heating assembly 20 is disposed in the air duct 1, the heating assembly 20 includes a first heating element 21 and a second heating element 22 which are independently disposed, and the first heating element 21 and the second heating element 22 are both provided with an input end and an output end for electrical connection.

By applying the technical solution of the embodiment, the first heating element 21 of the heating assembly 20 can be separately powered, the second heating element 22 can also be separately powered, and the first heating element 21 and the second heating element 22 can also be powered together. Because the heating value of the first heating member 21 and the second heating member 22 when heating simultaneously is different from the heating value of the first heating member 21 and the second heating member 22 when heating independently, the total heating value of the corresponding heating assembly 20 is different under the different electrifying modes, so that the temperature of hot air generated after the air entering the heating assembly 20 contacts the heating assembly 20 is different, thereby realizing multiple cooking functions, solving the problem of single cooking function of the cooking appliance, and improving the use experience of users.

Preferably, in the present embodiment, the heating powers of the first heat generating member and the second heat generating member are different. The structure can realize three different heating values under different electrifying modes, and corresponds to three different cooking functions. Thereby further richen the culinary art function, solved cooking utensil's the problem of culinary art function singleness, improved user's use experience. For example, when food needs to be thawed, only the first heater 21 may be energized; if it is desired to bake the food at the first preset temperature, only the second heat generating member 22 may be energized; if it is desired to roast the food at the second preset temperature (higher than the first preset temperature), the first and second

heat generating members

21 and 22 may be energized together.

As shown in fig. 2 and 3, in the present embodiment, the first heat generating element 21 includes a first substrate 211 and a first heat generating wire 212 wound on the first substrate 211. The first heat generating element 21 of the above structure is small in size compared to heat sources such as electric heating tubes and halogen tubes on the market, thereby reducing the size of the heat generating component 20.

As shown in fig. 2 and 3, in the present embodiment, the second heat generating member 22 includes a second substrate 221 and a second heat generating wire 222 wound on the second substrate 221. Similarly, the second heat generating member 22 of the above structure is small in size compared to a heat source such as an electrothermal tube or a halogen tube on the market, thereby reducing the size of the heat generating component 20.

It should be noted that, in the present embodiment, the difference between the heating powers of the first heat generating element 21 and the second heat generating element 22 can be realized through at least the following two forms: first, the number of winding turns of the first heating wire 212 is not equal to the number of winding turns of the second heating wire 222; second, the thickness of the first heater 212 is made different from the thickness of the second heater 222.

Because the volume of the fan of the cooking appliance is limited, if the overall length of the heating component 20 is too long, the amount of air blown to both ends of the heating component 20 in the length direction is too small, which causes too high temperature and affects the service life of the heating component 20. In order to solve the above problem, as shown in fig. 2 and 3, in the present embodiment, the air inlet 2 of the air duct 1 is located on a side wall of the casing 10, the first heat generating component 21 includes a first substrate 211 and a first heat generating wire 212 wound on the first substrate 211, the second heat generating component 22 includes a second substrate 221 and a second heat generating wire 222 wound on the second substrate 221, and the first substrate 211 and the second substrate 221 are stacked in a height direction n of the casing 10. Above-mentioned structure can minimize the whole length of heating element 20 to reduce the temperature rise at the both ends on the length direction of heating element 20, and then guarantee heating element 20's life. Note that the above-described "stacking" means stacking, and the first substrate 211 and the second substrate 221 have a distance in the height direction n.

In addition, if one heating wire is wound on a plurality of substrates, the more substrates are wound, the more complicated the process and the higher the defective rate. In this embodiment, the heating wires of the heating assembly 20 are actually divided into the independent first heating wire 212 and the independent second heating wire 222, so that the number of substrates required to be wound by a single heating wire can be reduced, the heating assembly 20 is easier to process, and the reject ratio is reduced.

The structure enables the heating value of the second heating part 22 to be larger than that of the first heating part 21, meanwhile, the length of the heating assembly 20 cannot be increased, the temperature rise of the two ends of the heating assembly 20 in the length direction is reduced, and the service life of the heating assembly 20 is further ensured. Note that the above-mentioned "stacking" means stacking, and two adjacent second substrates 221 have a distance in the height direction n of the housing 10.
