The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

A heat generating module 100 for a cooking apparatus according to an embodiment of the present invention is described below with reference to fig. 1 to 2.

As shown in fig. 1 to 2, a heat generating module 100 for a cooking apparatus according to an embodiment of the present invention includes: an outer tube 1 and a heat generating component 2.

Specifically, the outer tube 1 is formed in a tubular structure, and the heat generating component 2 includes: the heating device comprises a plurality of heating elements 21 and a plurality of connectors 22, wherein the plurality of heating elements 21 are arranged in the outer tube 1 at intervals, when the heating elements 21 are electrified, heat is generated to enable the cooking device 1000 to cook, two adjacent heating elements 21 are electrically connected through the connectors 22, and the cross section area of each heating element 21 is larger than that of each connector 22.

That is to say, both ends of the heating element 21 are respectively connected with the two connecting bodies 22, and both ends of the connecting body 22 are respectively connected with the two heating elements 21, therefore, the plurality of connecting bodies 22 can better connect the plurality of heating elements 21 together, after the power is turned on, the connecting bodies 22 can transmit the current to the heating element 21, and the heating element 21 can generate heat after the power is turned on, so that the heating module 100 can radiate heat energy to the food to be cooked in the cooking device 1000 to cook the food.

Wherein, generate heat through a plurality of heat-generating bodies 21, not only can improve to culinary art efficiency, can also be to the even heating of food to can improve culinary art effect.

In addition, by arranging a plurality of heating elements 21 in the outer tube 1, the outer tube 1 can isolate the heating elements 21 from other structures or objects, so as to prevent the heating elements 21 from being interfered by other structures when generating heat, and prevent the heating elements 21 from generating heat to influence the operation of other structures. Simultaneously, locate outer tube 1 back with a plurality of heat-generating bodies 21, a plurality of heat-generating bodies 21 can be to dispersing heat energy all around when generating heat to can make and be filled with heat energy in the outer tube 1, heat energy can see through outer tube 1 and radiate to around, because the pipe diameter of outer tube 1 is great, length is longer, consequently, when heat energy sees through outer tube 1 and radiates heat energy outwards, the heat energy of radiating on the food is more even, thereby makes food can heat more evenly, and then can improve the effect of culinary art.

Further, by setting the cross-sectional area of the heating element 21 larger than the cross-sectional area of the connecting member 22, the heating element 21 is not fused after the heating element 21 performs a heating operation for a long time, and the service life of the heating element 21 can be prolonged. The connecting body 22 is formed into a structure with a smaller cross section area, so that the resistance of the connecting body 22 is smaller, the connecting body 22 consumes less electric energy when conducting electricity, more electric energy can flow through the heating body 21, more heat energy can be radiated by the heating body 21, and the cooking efficiency can be improved. The cross-sectional area is understood to mean the projected area on a vertical plane.

According to the heating module 100 of the embodiment of the invention, the two adjacent heating elements 21 are electrically connected through the connecting body 22, so that the connecting body 22 can conduct electricity, and the heating element 21 connected with the connecting body 22 can generate heat after being electrified, further, the cross-sectional area of the heating element 21 is larger than that of the connecting body 22, therefore, after the heating element 21 performs heating operation for a long time, the heating element 21 cannot be fused, so that the service life of the heating element 21 can be prolonged, and the cross-sectional area of the connecting body 22 is smaller, so that the connecting body 22 consumes less electric energy when conducting electricity, and further more electric energy can flow through the heating element 21, so that the heating element 21 can radiate more heat energy, and the cooking efficiency can be improved.

In some embodiments of the present invention, the connecting body 22 is formed in a strip structure, that is, the projection area of the connecting body 22 in the vertical direction is smaller than the projection area in the horizontal direction, and by forming the connecting body 22 in a strip structure, not only is the connection between the connecting body 22 and the heating body 21 facilitated, but also the connecting body 22 can conduct electricity well.

Alternatively, the heating element 21 may be one of a sphere, an ellipsoid and a cuboid, that is, the heating element 21 may be a sphere, an ellipsoid or a cuboid, and of course, the heating element 21 may have a structure with other shapes, which is not limited herein. By forming the heat-generating body 21 in a spatial three-dimensional structure, the heat-generating body 21 can radiate heat energy to the surroundings well, so that the cooking efficiency of the heat-generating module 100 for food can be improved.

Alternatively, the connecting body 22 is a heat conducting member, and the heat generating coefficient of the connecting body 22 is lower than that of the heating body 21, that is, the connecting body 22 may be a conductive member and a heat conducting member, and the electric conduction is performed through the connecting body 22, so that the current can flow to the heating body 21, and the heating body 21 can generate heat; the heat is conducted through the connection body 22, so that the heat radiated from the plurality of heating bodies 21 is substantially the same, and the heating module 100 can heat the food more uniformly.

Further, by setting the heat generation coefficient of the connector 22 to be lower than that of the heating element 21, the connector 22 generates less heat, and the connector 22 can be prevented from being fused after the connector 22 generates high heat. And the heating coefficient of the heating body 21 is higher, so that the heating body 21 can emit high-temperature heat energy, the temperature of the heat energy radiated to the food to be cooked is higher, and the cooking efficiency can be improved.

Further, the connecting body 22 is a wire, that is, the connecting body 22 can be a wire, the cost of the heating module 100 can be reduced by setting the connecting body 22 as a wire, and the wire is a commonly used structure, so that a new wire can be conveniently found for replacement after the wire is damaged.

The heating element 21 is made of a high-melting-point material, and the melting point range of the heating element 21 is: the melting point of the heating element 21 can be limited to 1500-3400 ℃, that is, the melting point range of the heating element 21 can be limited to 1500-3400 ℃, for example, the melting point of the heating element 21 can be 1500 ℃, 2000 ℃, 2600 ℃, 3000 ℃, etc., without limitation. The melting point range of the heating element 21 can be limited to 1500-3400 ℃, so that the heating element 21 cannot be fused after long-time heating, and the service life of the heating element 21 can be prolonged.

In some embodiments of the present invention, the outer tube 1 includes a sleeve 11 and two sealing caps 12, and the two sealing caps 12 respectively seal both ends of the sleeve 11, so that after the two sealing caps 12 respectively seal both ends of the sleeve 11, the heat energy radiated from the heating body 21 can be outwardly radiated through the sleeve 11 and radiated to the food, and the heat energy radiated from the heating assembly 2 can fill the outer tube 1, thereby heating the food more uniformly.

Optionally, the sleeve 11 is made of an infrared transmission material that is transparent to a wide band, so that most of the waves radiated by the emitter after heating can be transmitted through the sleeve 11 to act on the food, so that the food can better absorb the transmitted waves, thereby improving the efficiency of the food being hotter.

It should be noted that, because different foods have different absorption ranges for the wavelengths during the cooking process, when the wave band radiated by the heat generated by the heating element 21 is blocked while passing through the sleeve 11, the food cannot absorb the wave band that makes the food quickly get hotter, so that the efficiency of cooking the food is low, and the taste of the food is affected even if the food is cooked in the cooking device 1000 for a long time. Therefore, the sleeve 11 is made of a material with a wide wavelength band, so that most of the wavelength band radiated by the heating body 21 can act on the food, the food can absorb the wavelength band for heating the food, and the cooking efficiency of the food is improved.

Further, the wavelength range of the radiation wave transmitted through the casing 11 is: 2.5-25 μm, i.e. the wavelength band of the radiation wave transmitted through the sleeve 11 may be defined between 2.5-25 μm, e.g. the wavelength band of the radiation wave transmitted through the sleeve 11 may be: 2.5-5 μm, 3-10 μm, 15-25 μm, etc., without limitation. By limiting the wavelength band passing through the sleeve 11 to 2.5-25 μm, most of the wave radiated by the heat emitted from the emitter can pass through the sleeve 11 and act on the food, so that the food can better absorb the wavelength band for heating the food, thereby improving the efficiency of the food in heating.

Optionally, the outer tube 1 further includes two terminals 13, the two terminals 13 are respectively disposed on end surfaces of the two sealing covers 12 away from each other, and the terminals 13 are connected to the connecting bodies 22 at two ends of the outer tube 1.

In one example, the terminal 13 is disposed on the sealing cover 12 facing away from the sleeve 11, one end of the terminal 13 can be connected to the connecting body 22, and the other end of the terminal 13 can be connected to another wire, so that after the power is applied, the current flows to the terminal 13 through the wire, then flows to the connecting body 22 through the terminal 13, and after the connecting body 22 is conductive, the current can be guided to the heating body 21, so that the heating body 21 can generate heat after being conductive, and the heating module 100 can perform cooking operation.

In another example, the connecting body 22 can be connected to a wire, and the terminal 13 is sleeved on the connecting portion of the connecting body 22 and other wires, so that the connecting body 22 and the wires can be connected together more firmly, and the connecting body 22 is prevented from being separated from the wires. Meanwhile, the terminal 13 is sleeved at the joint of the connector 22 and the lead, so that the safety can be improved, the electric leakage at the joint can be prevented, and potential safety hazards can be avoided.

The present invention also proposes a cooking apparatus 1000 having the heat generating module 100 of the above embodiment.

The combined toy cooking apparatus 1000 according to an embodiment of the present invention includes: a control member (not shown in the drawings) and the heat generating module 100, wherein the control member is electrically connected to the heat generating module 100 to control an operating parameter of the heat generating module 100, that is, the control member can control an operating state of the heat generating module 100, so that the heat generating module 100 can improve efficiency of cooking food.

In one example, the control part may regulate the voltage or power of the heat generating module 100, and thus, the voltage of the heat generating module 100 is regulated by the control part, so that the temperature when the heat generating body 21 generates heat can be regulated, and since the radiation intensity and wavelength of different temperatures are different, the wavelength band of the radiation wave of the heat generating body 21 can be changed by regulating the voltage. And the wave band of the radiant wave is adjusted so that the food to be cooked can absorb the heat energy of the wave band, thereby improving the cooking efficiency.

According to the cooking device 1000 of the embodiment of the invention, the control member is electrically connected with the heat generating module 100 to control the operating parameter of the heat generating module 100, so that the control member can control the operating state of the heat generating module 100, for example, the control member controls the voltage of the heat generating module 100, so that the wave band of the radiation wave of the heat generating body 21 is regulated and controlled, so that the food to be cooked can absorb the heat energy of the wave band, thereby improving the cooking efficiency of the cooking device 1000.

Optionally, the control part includes a thyristor, and thus, the thyristor controls the heating module 100, so that the thyristor conveniently adjusts the voltage across the heating module 100, and thus, the wave band radiated by the heating body 21 can be adjusted. In addition, the voltage of the heating module 100 is controlled by the thyristor, so that the temperature can be maintained after the cooking device 1000 reaches the cooking temperature, and the heating module 100 does not need to be switched on and off for many times during cooking, thereby protecting the heating module 100.
