Description

Technical Field

[0001] This invention relates to the field of kitchenware technology, specifically to a heat dissipation structure for a plasma stove. Background Technology

[0002] A plasma cooker is a new type of cooker that utilizes the properties of plasma. It uses high-voltage electricity to break down the air to form thermal plasma, converting electrical energy into heat energy, and ultimately obtaining a thermal plasma beam of ideal length and function. This thermal plasma beam, with flame-like characteristics, is used to heat cookware for cooking.

[0003] Plasma cooktops typically use a high-voltage transformer to boost voltage. The high-voltage circuit inside the transformer generates a lot of heat during operation. At the same time, the burner, circuit board, and power supply components also generate heat during operation. This heat accumulates inside the plasma cooktop and can cause some damage to the circuit structure and components. Therefore, it is necessary to dissipate heat from the inside of the plasma cooktop in a timely manner.

[0004] Existing plasma cookers typically only have a cooling fan installed outside the high-voltage coil to blow away the heat from the coil for rapid heat dissipation. However, there is no dedicated heat dissipation design for the other heat-generating structures, resulting in low heat dissipation efficiency. Summary of the Invention

[0022] See Figures 1-6 The present invention provides a heat dissipation structure for a plasma stove, including a burner support assembly 1, a control assembly 2, a high-voltage transformer assembly 3, and a heat dissipation assembly 5.

[0023] The burner head support assembly 1 includes a support frame 11 for mounting the burner head. A connector 6 is provided at the bottom of the support frame 11, and there is a gap between the connector 6 and the bottom of the support frame 11, with part of the burner head located within the gap. When the burner head mounted on the support frame 11 is in operation, some of the heat generated by the burner head is transferred down from the bottom of the support frame 11.

[0024] The control component 2 is connected to the connector 6. The control component 2 is the core control part of the entire structure. It is used to control the signal transmission between various parts or with the outside world, and at the same time control the operation of the furnace head.

[0025] The high-pressure pack assembly 3 is located at the bottom of the connector 6. The high-pressure pack assembly 3 is electrically connected to the control assembly 2. The high-pressure pack assembly 3 is used to provide high pressure to the furnace head that can break down the air to generate thermal plasma.

[0026] The heat dissipation assembly 5 includes a first fan 501, a second fan 502 and a third fan 503. The first fan 501 is used to dissipate heat from the burner head located in the gap between the connector 6 and the support frame 11. The second fan 502 and the third fan 503 dissipate heat from the control assembly 2 and the high-voltage pack assembly 3, respectively.

[0027] The first fan 501 forms a first heat dissipation air duct along the first direction between the connector 6 and the support frame 11, the second fan 502 forms a second heat dissipation air duct along the second direction with the control component 2, and the third fan 503 forms a third heat dissipation air duct along the third direction with the high voltage pack component 3. The first heat dissipation air duct, the second heat dissipation air duct and the third heat dissipation air duct are distributed in three dimensions, and the first direction and the second direction are horizontal, while the third direction is vertical.

[0028] The plasma stove heat dissipation structure provided by this invention utilizes a first fan 501 to dissipate heat from the burner head, forming a first heat dissipation duct along a first direction between the first fan 501, the connector 6, and the support frame 11. A second fan 502 is used to dissipate heat generated by the control component 2, forming a second heat dissipation duct along a second direction with the control component 2. A third fan 503 is used to dissipate heat generated by the high-voltage coil component 3, forming a third heat dissipation duct along a third direction with the high-voltage coil component 3. The first heat dissipation duct is located at the top layer of the plasma stove heat dissipation structure, the third heat dissipation duct is located at the bottom layer with its heat dissipation direction vertically downwards, and the second heat dissipation duct is located in the middle layer, with its second direction intersecting with the first direction of the first heat dissipation duct. This design allows for the rational distribution of three heat dissipation channels in a three-dimensional space from top to bottom, effectively dissipating heat from the high-voltage coil component 3, the burner head, and the control component 2, thereby improving heat dissipation efficiency.

[0029] like Figure 6 As shown, a conductive plate 9 is connected to the bottom of the connector 6. The conductive plate 9 is connected to the electrode structure of the burner head, and the conductive plate 9 is electrically connected to the control component 2 and the high-voltage transformer component 3 respectively. The control component 2 and the high-voltage transformer component 3 are connected to the conductive plate 9, allowing the electrode structure on the burner head to be electrically connected simultaneously. For the bottom of the burner head's electrode structure to connect to the conductive plate 9, a portion must pass through the gap between the connector 6 and the bottom of the support frame 11. Placing the first fan 501 at this location provides better heat dissipation.

A baffle is provided at the bottom edge of the circular top of the connector 6, and the baffle is integrally formed with the top. The conductive plate 9 is located within the space enclosed by the baffle. An extension section 601 is connected to the right side of the top of the connector 6. The extension section 601 extends horizontally to the right, and the surface of the extension section 601 is horizontal with the top surface of the connector 6. A baffle is symmetrically designed on both sides of the extension section 601 and at the top edge of the connector 6. A notch is provided on the left side of the top of the connector 6 corresponding to the position of the extension section 601. When the connector 6 is placed at the bottom of the support frame 11, the top of the baffle abuts against the bottom of the support frame 11, so that a cavity is formed between the top of the connector 6, the baffle, and the bottom of the support frame 11. The first fan 501 is fixed at the extension section 601 and introduces cold air into the cavity from the opening of the extension section 601.

The first mounting slot 701 has many perforated ventilation holes. The current transformer 8 is installed at the bottom of the first mounting slot 701, and the heat sink 504 can dissipate heat from the current transformer 8 and the adjacent high-voltage transformer assembly 3. The current transformer 8 is electrically connected to the high-voltage transformer assembly 3. A side plate 703 is provided on the left side of the fixing member 7, and a power board 4 is mounted on the side plate 703. The second fan 502 is provided on the right side of the fixing member 7.
