Description

Technical Field

[0001] The invention relates to an electric heating device, in particular to an electric flame stove that is not picky about pots. Background Art

[0002] Gas stoves are commonly used cooking appliances, but they have certain safety hazards and pollution problems. With the development of science and technology, electric flame stoves that use electricity to generate fire have appeared on the market. The working principle of the electric flame stove is as follows: the power supply voltage is boosted by a booster device, so that the arc breaks through the air to generate a plasma flame to provide the heat source required for cooking food; the electric flame stove has the following advantages: ① The working principle is to generate fire with electricity, so no fuel is needed, so it can eliminate safety hazards such as gas leakage poisoning and gas tank explosion; ② The thermal efficiency of the electric flame stove can reach 85%, while the first-level energy efficiency of traditional gas stoves is usually only 63%, which shows that the thermal efficiency of the electric flame stove is higher than that of traditional gas stoves; ③ The electric flame stove is highly safe. When you pick up the pots and utensils, the electric flame stove will automatically extinguish the fire. When you put down the pots and utensils, the electric flame stove can generate fire, which can avoid wasting electricity and effectively prevent related safety accidents; ④ The pots and utensils are grounded, so when using the electric flame stove, you can directly contact the pots and utensils, which is safe. However, based on the working principle of electric ignition, traditional electric flame stoves have a defect that is difficult to overcome: the pots and utensils used in conjunction with the electric flame stove must have conductive properties to ensure that an arc that can penetrate the air is generated between the discharge device and the conductive pots and utensils, thereby generating a plasma flame. Therefore, commonly used ceramic utensils, glass utensils, stone utensils and other non-conductive utensils cannot be used in conjunction with the electric flame stove.

[0003] For example, Chinese patent document CN108758723A discloses an electric heating device and an electric heating stove, which specifically discloses: a conductive bracket for placing a conductive pot and grounded, and an electric heating assembly; the electric heating assembly includes a booster, a power supply for supplying power to the booster, and a discharge device electrically connected to the booster and used to cooperate with the conductive pot to generate an arc. It can be seen that the electric heating stove needs to be used in conjunction with a conductive pot (conductive vessel), that is, it is not compatible with non-conductive vessels.

[0004] Therefore, further improvements are needed. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and to provide an electric flame stove that is not picky about pots.

[0009] As another specific solution: the detection device also includes a periscope assembly for changing the direction of the detection ray; more than one periscope assembly is provided and is located between the emitting component and the receiving component; the periscope assembly includes a reflecting part for reflecting the detection ray to change its direction; the emitting component and / or the receiving component are away from the cookware.

[0010] As another specific solution: a shielding portion is provided on the stove body; the periscope assembly is floatingly arranged relative to the stove body; when the pot or utensil is placed on the periscope assembly, the periscope assembly sinks relative to the stove body, so that the shielding portion blocks the emission port of the periscope assembly, resulting in the receiving component not receiving the detection ray, and the control module allows the discharge assembly to work.

[0011] As another specific solution: an elastically movable radiation guiding component is provided on the stove body, the radiation guiding component is connected to the periscope assembly, and an elastic member is provided between the radiation guiding component and the stove body; a radiation guiding through hole is provided on the radiation guiding component, and one end of the radiation guiding through hole corresponds to the transmitting end of the transmitting component or the receiving end of the receiving component.

[0012] As another specific solution: the discharge assembly includes a discharge head and a discharge support rod; the discharge head and the discharge support rod are threadedly connected to each other; a heat dissipation ring is arranged under the discharge head, and the heat dissipation ring extends outward in a circumferential direction with the discharge support rod as the center.

[0013] As another specific solution: the stove body includes a support assembly and a stove assembly that are detachable from each other; the heat-conducting energy-gathering component is arranged on the support assembly, and the discharge assembly is arranged on the stove assembly; a discharge cavity is arranged on the support assembly, and a discharge end of the discharge assembly is arranged on the discharge cavity.

[0014] As another specific scheme: the support assembly includes a first fixed bracket, a protective cover and a second fixed bracket; the protective cover is clamped and fixed between the first fixed bracket and the second fixed bracket, the first fixed bracket and the second fixed bracket are interconnected by a first fastening component, the heat-conductive energy-focusing component is grounded through the first fastening component, the heat-conductive energy-focusing component is at least partially exposed on the inner side of the annular first fixed bracket, the pot or utensil is supported on the heat-conductive energy-focusing component and / or the first fixed bracket, and the heat-conductive energy-focusing component and the protective cover jointly surround the discharge chamber.

[0017] The beneficial effects of the present invention are as follows:

[0018] By setting a heat-conducting energy-gathering component, the electric arc generated between the discharge component and the heat-conducting energy-gathering component breaks through the air to generate a plasma flame, and the plasma flame burns and heats the heat-conducting energy-gathering component to generate high-temperature heat, and the heat is transferred to the pots and utensils through the heat-conducting energy-gathering component, so that the food in the pots and utensils can be heated and cooked. In this electric flame stove, the heat-conducting energy-gathering component cooperates with the discharge component to generate a plasma flame, and the heat is then transferred to the pots and utensils through the heat-conducting energy-gathering component. Therefore, the material of the pots and utensils is not restricted, which greatly improves the versatility of the electric flame stove, eliminates the limitations on pots and utensils, meets the different usage needs of users, and improves the user experience;

[0019] In order to improve the safety of use, the electric flame stove is provided with a detection device for detecting whether there are any cookware or utensils placed on the electric flame stove, and the detection device receives and sends detection rays; that is, when there are no cookware or utensils on the electric flame stove, the detection device can smoothly receive the corresponding detection rays, and the control module does not allow the discharge component to work; when there are cookware or utensils placed on the electric flame stove, the detection device cannot receive the corresponding detection rays, and the control module allows the discharge component to work; it can be seen that the detection device can effectively detect whether there are cookware or utensils on the electric flame stove, so that the control module can control whether the discharge component works or not according to the detection result, and it has high safety and simple and reasonable structure. Taking into account that when the electric flame stove is in working state, the temperature around the cookware is high, and the transmitting component and the receiving component in the detection device are often not resistant to high temperature; in order not to affect the normal use of the transmitting component and the receiving component, the detection device also includes a periscope component, which changes the direction of the detection ray by reflection. Since the direction of the detection ray can be changed by the periscope component, the heating component and the receiving component can be respectively set at positions away from the cookware. By arranging the periscope component at a set angle and position between the transmitting component and the receiving component, it can be ensured that the detection ray can be smoothly sent and received, effectively solving the problem that the heating component and the receiving component are not resistant to high temperature.

[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0036] See also Figure 1-Figure 15 The electric flame stove involved in this embodiment includes a stove body, a control module, and a discharge component electrically connected to the control module. The control module controls whether the discharge component works or not, and the control module is electrically connected to the power supply terminal. The control module and the discharge component are respectively arranged on the stove body. The electric flame stove also includes a heat-conducting energy-gathering component 4 that is grounded and conducts heat to the pot 300. An arc is generated between the heat-conducting energy-gathering component 4 and the discharge component in the energized state to generate an electric flame, and the electric flame heats the pot 300 through the heat-conducting energy-gathering component 4. The electric flame stove is provided with the heat-conducting energy-gathering component 4, so that the arc generated between the discharge component and the heat-conducting energy-gathering component 4 breaks through the air to generate a plasma flame. The plasma flame burns and heats the heat-conducting energy-gathering component 4 to generate high-temperature heat. The heat is transferred to the pot 300 through the heat-conducting energy-gathering component 4, so that the food in the pot 300 can be heated and cooked. In the electric flame stove, the heat-conducting energy-focusing component 4 cooperates with the discharge assembly to generate a plasma flame, and the heat is then transferred to the pot utensil 300 through the heat-conducting energy-focusing component 4. Therefore, the material of the pot utensil 300 is not restricted, which greatly improves the versatility of the electric flame stove, eliminates the limitations of the pot utensil 300, meets the different usage requirements of users, and improves the user experience.

[0037] Furthermore, the electric flame cooker also includes a detection device for detecting cookware 300, the purpose of which is to ensure that the control module allows the discharge component to work only when there is a cookware 300 by detecting whether there is a cookware 300 placed on the electric flame cooker; the detection device includes a transmitting component 25 for emitting a detection ray B and a receiving component 26 for receiving the detection ray B; in this embodiment, the detection ray B is preferably an infrared ray, and can also be other spectral rays; the receiving component 26 is electrically connected to the control module to feedback to the control module whether the detection ray B is received; the transmission route of the detection ray B passes through the position for placing the cookware 300, that is, the detection ray B passes above the top surface of the electric flame cooker; when no cookware is placed on the electric flame cooker utensil 300, the transmission path of the detection ray B is not blocked, so that the receiving component 26 can smoothly receive the detection ray B emitted by the transmitting component 25. In this case, the control module recognizes that there is no pot utensil 300 on the electric flame cooker, so the control module does not allow the discharge component to work, effectively preventing the discharge component from working when no pot utensil 300 is placed; when the pot utensil 300 is placed on the electric flame cooker, there is an obstruction on the transmission path of the detection ray B, so that the detection ray B emitted by the transmitting component 25 is blocked, resulting in the receiving component 26 not receiving the detection ray B. In this case, the control module recognizes that there is a pot utensil 300 on the electric flame cooker, so the control module allows the discharge component to work, ensuring that the user uses the electric flame cooker in a safe condition.

[0038] Furthermore, the transmission route of the detection ray B is a straight line. Since both the emitting component 25 and the receiving component 26 are not heat-resistant, the emitting component 25 and the receiving component 26 need to be away from the cookware 300. In order to ensure that the transmission route of the detection ray B passes above the top surface of the electric flame cooker, the detection device also includes a periscope assembly 1 for changing the direction of the detection ray B. In this embodiment, two groups of periscope assemblies 1 are arranged (according to actual needs, more than one group of periscope assemblies 1 can be arranged), and are located between the emitting component 25 and the receiving component 26 (specifically, the periscope assembly 1 is located on the transmission route of the detection ray B between the emitting component 25 and the receiving component 26). The periscope assembly 1 includes a reflecting part 1011 for reflecting the detection ray B to change its direction. The emitting component 25 and the receiving component 26 are respectively away from the cookware 300. Specifically, the emitting component 25 is located below one group of periscope assemblies 1, and the receiving component 26 is located below another group of periscope assemblies 1. The two groups of periscope assemblies 1 cooperate face to face, and the emitting ends of the two groups of periscope assemblies 1 are respectively higher than the top surface of the electric flame cooker; see Figure 3 and Figure 4In the absence of the cookware 300, the detection ray B is transported as follows: the emitting component 25 emits the detection ray B upward, the detection ray B is transported to a group of periscope components 1, and changes its direction for the first time under the reflection of the group of periscope components 1. After changing its direction, the detection ray B is transported above the top surface of the electric flame cooker, and then the detection ray B is transported to another group of periscope components 1, and changes its direction for the second time under the reflection of the group of periscope components 1. After changing its direction, the detection ray B is transported downward to the receiving component 26, and the receiving component 26 receives the detection ray B.

[0039] Furthermore, the periscope assembly 1 includes a periscope cover 101, a light-transmitting sheet 102 and a periscope seat 103; the periscope cover 101 is fixedly arranged on the periscope seat 103, and the reflector 1011 is arranged on the periscope cover 101; the light-transmitting sheet 102 is fixedly arranged on the periscope seat 103 and corresponds to the emission port 1031 on the periscope seat 103. The two sets of periscope assemblies 1 in the same detection device are respectively arranged at the top edge of the electric flame stove, and the pot utensil 300 is generally placed between the two periscope assemblies 1.

[0040] Furthermore, a vertical shielding part 3011 is provided on the stove body; the periscope assembly 1 is arranged to float up and down relative to the stove body; when the pot 300 is placed on the periscope assembly 1, the periscope assembly 1 sinks relative to the stove body, so that the shielding part 3011 blocks the emission port 1031 of the periscope assembly 1, resulting in the receiving component 26 not receiving the detection ray B, and the control module allows the discharge assembly to work. Specifically, when the outer diameter of the pot 300 is smaller than the spacing between the two groups of periscope assemblies 1, the pot 300 is placed between the two groups of periscope assemblies 1, and the detection ray B is blocked by the pot 300; when the outer diameter of the pot 300 is larger than the spacing between the two groups of periscope assemblies 1, the pot 300 is placed on each periscope assembly 1, so that each periscope assembly 1 sinks, and the detection ray B is blocked by the corresponding shielding part 3011.

[0041] Furthermore, an elastically movable radiation guide component 8 is provided on the stove body, and the top of the radiation guide component 8 is connected to the periscope seat 103 in the periscope assembly 1. An elastic member 9 is provided between the radiation guide component 8 and the stove body. The elastic member 9 is a coil spring sleeved on the outside of the radiation guide component 8. One end of the elastic member 9 abuts against the radiation guide component 8 and the other end abuts against the stove body. A radiation guide through hole 801 extending along the axis is provided on the inside of the radiation guide component 8. One end of the radiation guide through hole 801 passes through the top of the radiation guide component 8 and is connected to the reflection part 1. 011, the other end of the guiding through hole 801 passes through the bottom of the guiding component 8, and corresponds to the transmitting end of the transmitting component 25 or the receiving end of the receiving component 26; the detection ray B emitted by the transmitting component 25 is transmitted to the reflecting part 1011 in one group of periscope components 1 under the conduction of the guiding through hole 801; the detection ray B enters another guiding through hole 801 after being reflected by the reflecting part 1011 in another group of periscope components 1, and is transmitted to the receiving component 26 under the conduction of the guiding through hole 801.

[0042] Furthermore, in the electric flame cooker of this embodiment, two sets of detection devices are provided, and the detection rays B emitted by the two sets of detection devices pass over the top surface of the electric flame cooker respectively.

The buckle position 1001 and the buckle hole 2401 are screwed together to realize a detachable screw-on connection between the support assembly 100 and the stove assembly 200. In order to ensure the assembly stability between the support assembly 100 and the stove assembly 200, a positioning column 12 is inserted between the support assembly 100 and the stove assembly 200 to prevent the support assembly 100 and the stove assembly 200 from rotating relative to each other.
