Description

Technical Field

[0001] This invention relates to the field of electric gas stove technology, and in particular to a dual-cavity heat circulation structure. Background Technology

[0002] An electric gas stove is a new type of stove that uses electricity to start a fire without the need for fuel. It uses clean electricity as its energy source and low-temperature thermal plasma technology as its foundation, with a plasma torch that outputs stable power from multiple points to achieve cooking functions.

[0003] Patent CN215446565U discloses a plasma electric flame stove. The disclosed stove features a grounding probe on its base, which generates an ionization field with the electrodes. When a pot is placed on the stove, it contacts the grounding probe. When the electrodes are energized, an ionization field is generated between the electrodes and the pot, ionizing the air between them and generating significant heat around the electrodes, thus heating the pot. Therefore, this type of electric flame stove automatically extinguishes the flame when the pot is removed. It is unsuitable for using non-conductive pots such as earthenware or ceramic pots.

[0004] In addition, because the electrodes of an electric stove are connected to the cookware by high voltage, harmful gases such as ozone and nitrogen oxides are generated during operation. Since the electrodes are connected to the outside atmosphere, these ozone and nitrogen oxides will continue to generate new ozone and nitrogen oxides after they are released into the atmosphere, polluting the environment.

[0017] The bottom of the second circular groove is provided with a connecting hole extending to the outside. The drive shaft of the motor passes through the connecting hole and connects to the fan, which is located in the second circular groove.

[0018] To achieve one or more of the above objectives or other objectives, the present invention also proposes a dual-cavity heat circulation structure for an electric gas stove, comprising: a pot ring, a pot ring bottom plate, an electrode plate, and a second guide plate.

[0019] The pot ring is disposed on the bottom plate of the pot ring for placing the pot, and when the pot is placed, the pot ring, the bottom plate of the pot ring and the pot form a first cavity;

[0020] The second guide plate has a second groove structure, and the bottom plate of the pot ring, the electrode plate and the second guide plate are stacked in sequence, forming a second cavity between the second guide plate and the electrode plate;

[0021] The bottom plate of the pot ring has a first reflux hole and multiple electrode holes. The electrode plate is provided with multiple second electrode grooves corresponding to the electrode holes and a second reflux hole corresponding to the first reflux hole. The bottom of each second electrode groove has a second pin hole and a second guide hole communicating with the first cavity. The second guide plate is also provided with multiple third pin holes. Each second electrode groove is provided with a hollow first electrode. The electrode plate and the second guide plate are provided with electrode needles that pass through the second pin hole and the third pin hole in sequence. One end of the electrode needle is located outside the second guide plate, and the other end is located inside the first electrode and connected to a second electrode that does not contact the first electrode. A flow channel communicating with the first cavity and the second cavity is formed between the first electrode and the second electrode.

[0022] Furthermore, the electrode plate also includes: a plurality of second flow guides, the electrode plate is provided with a plurality of mounting holes, a limit ring is provided on the side wall of any mounting hole, the second electrode groove is formed by the second flow guides being installed in the mounting holes and engaging with the limit rings, and the second pinhole and the second flow guide hole are located on the second flow guides.

[0023] Further, i) the second guide member is formed by connecting a first cylinder to a second cylinder, the side wall of the first cylinder is provided with a plurality of inclined grooves, the second guide hole is formed by the side wall of the inclined grooves and the mounting hole, the plurality of inclined grooves are arranged clockwise or counterclockwise on the side wall of the first cylinder, and the second pinhole is located at the axial position of the first cylinder and the second cylinder; or,

[0027] The bottom of the fan mounting slot has a through-hole leading to the outside. The drive shaft of the motor passes through the through-hole and connects to the fan, which is located in the fan mounting slot.

[0028] Implementing the embodiments of the present invention will have the following beneficial effects:

[0029] With the aforementioned dual-cavity thermal circulation structure, when the cookware is placed, the pot ring, the pot ring base plate, and the cookware together form the first cavity. The pot ring base plate covers the first groove-shaped structure set in the first guide plate to form the second cavity. As long as a fan is installed in the second cavity at the position corresponding to the first return hole, the first and second cavities can form a circulation through the first return hole and the flow channel. That is, air from the first cavity can flow into the second cavity from the first return hole, and air from the second cavity can flow into the first cavity from the flow channel. At the same time, since the high-temperature plasma is generated between the first and second electrodes, that is, generated in the flow channel, it does not rely on the cookware as an arc-initiating electrode. During the process of airflow from the second cavity into the first cavity, the high-temperature plasma generated between the first and second electrodes can be applied to the cookware. Thus, non-conductive cookware such as casserole and ceramic pots can also be used on electric gas stoves. Furthermore, since the generation of ozone and nitrogen oxides is a reversible process in a relatively closed space, and the first and second cavities are not connected to the outside, only a very small amount of ozone and nitrogen oxides will be generated during operation, effectively reducing the generation of harmful gases.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to limit the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects and not to describe a particular order.

[0048] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0049] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0050] Example 1

[0051] Reference Figures 1 to 5 This invention proposes a dual-cavity thermal circulation structure for electric gas stoves, comprising: a pot ring 1, a pot ring bottom plate 2, a first guide plate 3a, and multiple first guide components 4a made of insulating materials; the first guide plate 3a may be ceramic, and the first guide components 4a may be made of insulating and high-temperature resistant materials such as ceramic and mica.

[0052] A pot ring 1 is mounted on a pot ring base plate 2 for placing cookware. When the cookware is placed on the pot ring, the pot ring 1, the pot ring base plate 2, and the cookware together form a first cavity. Notably, the top of the pot ring 1 has an inward-facing chamfer 11 for fitting the cookware. The center of this chamfer 11 is located on one side of the cookware. This allows the pot ring 1 to better fit the round-bottomed pot, resulting in a better seal within the first cavity. Figure 5 For example, since the top of the pot ring 1 is flat, it fits well with flat-bottomed pans, and the first cavity has good sealing properties. Therefore, the solution proposed in this invention is suitable for both round-bottomed and flat-bottomed pans. The side wall of the pot ring 1 has an opening, which is sealed with transparent glass to form an observation window 12. Figure 1 and Figure 5 As shown, since the first cavity is sealed, the observation window 12 is provided to facilitate the user's observation and adjustment of the firepower.

[0053] The bottom plate 2 of the pot ring has a first return hole 21 and multiple electrode holes 22. The first guide plate 3a has a first groove structure 3a1. The first guide plate 3a is connected to the bottom of the pot ring 2, and the bottom plate 2 covers the first groove structure 3a1 to form a second cavity. The first return hole 21 should be understood as a hole structure, which can be a single hole or a mesh structure, as long as it allows air to flow. In some embodiments, the first return hole 21 can be multiple raised mesh holes. Most cookware used by general users is round. The first groove structure 3a1 mentioned above can be a circular groove, or it can include a first circular groove 3a11 set on the first guide plate 3a and a second circular groove 3a12 set at the bottom of the first circular groove 3a11. The bottom of the second circular groove 3a12 is provided with a connecting hole that extends to the outside. A fan 9 is arranged at the position of the second circular groove 3a12 corresponding to the connecting hole. A motor 8 is arranged at the bottom of the first guide plate 3a. The drive shaft of the motor 8 passes through the connecting hole and connects to the fan 9. This configuration can make the flame of the entire electric stove hit the cookware more evenly, so that the cookware is heated more evenly.

[0054] The aforementioned multiple first flow guides 4a are disposed at the bottom of the first groove structure 3a1. Each first flow guide 4a has a first electrode groove 4a1, which corresponds one-to-one with the electrode hole 22. The first electrode groove 4a1 also has a first flow guide hole that connects to the first cavity and a first pin hole 4a21 that connects to the outside of the first flow guide 4a. A hollow first electrode 5 is disposed on the first electrode groove 4a1. The first pin hole 4a21 is provided with an electrode needle 6 that passes through the first flow guide 4a. One end of the electrode needle 6 is located outside the first flow guide plate 3a, and the other end is located inside the first electrode 5 and connected to a second electrode 7 that does not contact the first electrode 5. A flow channel connecting the first cavity and the second cavity is formed between the first electrode 5 and the second electrode 7. The first electrode 5 is connected to one pole of the power supply. When the first electrode 5 passes through the electrode hole 22, it can be in sealed contact with the bottom plate 2 of the pot ring and connected to one pole of the power supply through the bottom plate 2 of the pot ring. The second electrode 7 is connected to the other pole of the power supply through the electrode needle 6. More specifically, the first guide element 4a is formed by a circular groove connecting a cylinder 4a2. Multiple first guide holes are multiple first oblique holes 4a11 provided on the sidewall of the circular groove. The multiple first oblique holes 4a11 are arranged clockwise or counterclockwise on the sidewall of the circular groove. The first pinhole 4a21 is located at the axis of the cylinder 4a2 and connects to the circular groove. During installation, the bottom of the first groove-shaped structure 3a1 has multiple slots, and the multiple first guide elements 4a are correspondingly engaged with these slots, such as... Figure 1 and Figure 3 As shown.

[0055] In practical use, the motor 8 drives the fan 9. The first cavity and the second cavity can form a circulation through the first return hole 21 and the flow channel. That is, the air in the first cavity can flow into the second cavity from the first return hole 21, and the air in the second cavity can flow into the first cavity from the flow channel. At the same time, since the high-temperature plasma is generated between the first electrode 5 and the second electrode 7, that is, generated in the flow channel, it does not rely on the cookware as one of the electrodes for arc initiation. During the process of the airflow flowing from the second cavity into the first cavity, it can hit the cookware with the high-temperature plasma generated between the first electrode 5 and the second electrode 7. Thus, non-conductive cookware such as casserole and ceramic pots can also be used on the electric stove. During this process, since the circular groove sidewall of the first guide member 4a is provided with multiple first oblique holes 4a11 arranged clockwise or counterclockwise, the air inlet to the flow channel is multiple oblique holes, which can make the air in the flow channel rotate. After the air rotates, the position of the arc generated by the first electrode 5 and the second electrode 7 can rotate, that is, the position of the high-temperature plasma generated changes, preventing a certain point from being broken down by excessively high temperature for a long time, and extending the service life of the first electrode 5 and the second electrode 7. Furthermore, since the generation of ozone and nitrogen oxides is a reversible process in a relatively enclosed space, and the first and second chambers are not connected to the outside world, only a very small amount of ozone and nitrogen oxides will be generated during operation, effectively reducing the generation of harmful gases.

[0056] Example 2

[0057] Reference Figures 6 to 13 The present invention also proposes a dual-cavity heat circulation structure for electric gas stoves, comprising: a pot ring 1, a pot ring bottom plate 2, an electrode plate 10, and a second guide plate 3b; the second guide plate 3b may be made of ceramic, which can be insulated and resistant to high temperatures.

[0058] A pot ring 1 is mounted on a pot ring base plate 2 for placing cookware. When the cookware is placed on the pot ring, the pot ring 1, the pot ring base plate 2, and the cookware together form a first cavity. Notably, the top of the pot ring 1 has an inward-facing chamfer 11 for fitting the cookware. The center of this chamfer 11 is located on one side of the cookware. This allows the pot ring 1 to better fit the round-bottomed pot, resulting in a better seal within the first cavity. Figure 12 For example, since the top of the pot ring 1 is flat, it fits well with flat-bottomed pans, and the first cavity is also well-sealed. Therefore, the solution proposed in this invention is suitable for both round-bottomed and flat-bottomed pans. The side wall of the pot ring 1 has an opening, which is sealed with transparent glass to form an observation window 12. Since the first cavity is sealed, the observation window 12 facilitates user observation and adjustment of the heat.

[0059] The bottom plate 2 of the pot ring has a first return hole 21 and multiple electrode holes 22. The second guide plate 3b is provided with a second groove structure 3b1. The bottom plate 2 of the pot ring, the electrode plate 10 and the second guide plate 3b are stacked in sequence, and a second cavity is formed between the second guide plate 3b and the electrode plate 10. The first return hole 21 should be understood as a hole structure. It can be a single hole or a mesh structure, as long as it can allow air to flow. In some embodiments, the first return hole 21 can be multiple mesh holes with protrusions, which can prevent some water from flowing into the second cavity.

[0060] The electrode plate 10 is provided with a plurality of second electrode grooves 101 corresponding to the electrode holes 22, and a second return hole 102 corresponding to the first return hole 21. The bottom of the second electrode grooves 101 is insulated. Each second electrode groove 101 has a second pinhole 4b21 and a second guide hole 4b12 communicating with the first cavity at its bottom. Specifically, the second electrode grooves 101 can be configured as follows: a plurality of mounting holes 103 are provided on the electrode plate 10, that is, a limit ring 1031 is provided on the side wall of each mounting hole 103. The second electrode grooves 101 are formed by a second guide member 4b made of ceramic or mica being installed in the mounting hole 103 and engaging with the limit ring 1031. The second pinhole 4b21 and the second guide hole 4b12 are provided on the second guide member 4b. The specific structure of the second guide member 4b can be any of the following forms:

[0061] i) The second guide member 4b is formed by connecting the first cylinder 4b1 and the second cylinder 4b2. The side wall of the first cylinder 4b1 is provided with multiple inclined grooves 4b11. The second guide hole 4b12 is formed by the inclined grooves 4b11 and the side wall of the mounting hole 103. The multiple inclined grooves 4b11 are arranged clockwise or counterclockwise on the side wall of the first cylinder 4b1. The first pinhole 4a21 is located at the axial position of the first cylinder 4b1 and the second cylinder 4b2, such as... Figure 11 As shown; or,

[0062] ii) The second guide member 4b is formed by connecting the first cylinder 4b1 and the second cylinder 4b2. The second guide hole 4b12 is a plurality of second oblique holes provided on the first cylinder 4b1. The plurality of second oblique holes are arranged clockwise or counterclockwise on the first cylinder 4b1. The second pinhole 4b21 is located at the axial position of the first cylinder 4b1 and the second cylinder 4b2, such as... Figure 10 As shown.

[0063] The second groove-shaped structure 3b1 of the second guide plate 3b can be formed by combining a fan mounting groove 3b11 and a guide groove 3b12. Specifically, the fan mounting groove 3b11 is located in the middle of the second groove-shaped structure 3b1. The second guide plate 3b has multiple third pin holes 3b13. The guide groove 3b12 surrounds the outer periphery of the third pin holes 3b13 and connects to the fan mounting groove 3b11. The second cavity is formed after the electrode plate 10 is connected to the top of the second guide plate 3b and the guide groove 3b12 is covered. At this time, a guide channel is formed inside the guide groove 3b12. The guide channel connects to the second guide hole 4b12, and the second pin hole 4b21 and the third pin hole 3b13 are connected. The bottom of the fan mounting groove 3b11 has a connecting hole that extends to the outside. A fan 9 is arranged at the position of the second circular groove 3a12 corresponding to the connecting hole. A motor 8 is arranged at the bottom of the second guide plate 3b. The drive shaft of the motor 8 passes through the connecting hole and connects to the fan 9.

[0064] Each of the aforementioned second electrode slots 101 is provided with a hollow first electrode 5. An electrode needle 6 is provided, which passes through the second needle hole 4b21 and the third needle hole 3b13. One end of the electrode needle 6 is located outside the second guide plate 3b and is used to connect to one pole of the power supply. The other end is located inside the first electrode 5 and is connected to a second electrode 7 that is not in contact with the first electrode 5. A flow channel connecting the first cavity and the second cavity is formed between the first electrode 5 and the second electrode 7. Since the sidewall of the first electrode 5 is in contact with the electrode plate 10, the electrode plate 10 can be a high-temperature resistant insulating plate such as a ceramic plate or a mica plate. The first electrode 5 can be connected to the other pole of the power supply through the bottom plate 2 of the pot ring.

[0065] The cookware commonly used by ordinary users is round. The multiple third pinholes 3b13 are arranged in two or more circles. That is, the first electrode 5 and the second electrode 7 are also arranged in two or more circles. This configuration allows the flame of the entire electric stove to hit the cookware more evenly, making the cookware heat more evenly.

[0066] During use, high-temperature plasma is generated between the first electrode 5 and the second electrode 7. The fan 9 drives the air in the first and second cavities to circulate, meaning that air from the first cavity can flow into the second cavity through the circulation vent, and air from the second cavity can flow into the first cavity through the second guide hole 4b12. During the flow from the first cavity to the second cavity, the airflow can propel the high-temperature plasma generated between the first electrode 5 and the second electrode 7 onto the cookware, allowing non-conductive cookware such as casseroles and ceramic pots to be used on the electric stove. Throughout the entire process, hot air outflow is effectively prevented, and heating efficiency is greatly improved. Regardless of whether it is in i) or ii) above, the air inlet of the second guide 4b is inclined. This causes the air to rotate after entering the channel, which in turn causes the position of the electric arc to rotate, thus changing the position of the high-temperature plasma generation. This prevents the electric arc from being fixed in position, avoiding damage to the arc-initiating positions of the first electrode 5 and the second electrode 7, and extending the service life of the first electrode 5 and the second electrode 7. Furthermore, since the generation of ozone and nitrogen oxides is a reversible process, they can only reach a certain concentration in a relatively enclosed space. The first and second chambers are not connected to the outside world, and only a very small amount of ozone and nitrogen oxides will be generated during operation, effectively reducing the generation of harmful gases.

[0067] Obviously, the embodiments described above are merely some embodiments of the present invention, not all embodiments. The accompanying drawings show preferred embodiments of the present invention, but do not limit the patent scope of the present invention.
