Description

Technical Field

[0001] This utility model relates to the field of stoves, and in particular to a gas-electromagnetic integrated stove. Background Technology

[0002] Existing technology, Chinese utility model patent CN201420696921.1, discloses a dual-burner stove integrating an induction cooker and a gas cooker. This dual-burner stove includes a bottom shell with an upper opening, a panel, an induction cooker head, and a gas cooker head. It includes a partition plate, which is longitudinally positioned within the bottom shell's cavity, forming two independent spaces: a right shell and a left shell. The upper part of the partition plate is fitted to the panel and airtight. It also includes a centrifugal fan and an air duct. The centrifugal fan is located within the left shell's cavity, and the air duct is located within the right shell's cavity and passes through the partition plate. The left end of the air duct is connected to the centrifugal fan's outlet, and the right end is connected to the gas cooker's burner. The centrifugal fan transports hot air from the induction cooker within the left shell through the air duct to the gas cooker's burner, where it mixes with the gas to form a gas mixture. This preheating of the gas mixture and accelerated airflow ensure complete combustion of the gas. The problems are as follows: the power board and control circuit board connected to the induction cooker are located in a separate box on one side of the bottom shell, while the igniter and battery connected to the gas cooker are located in a separate box on the other side of the bottom shell. The electronic control parts of the induction cooker and the gas cooker are independent of each other, which makes it very inconvenient to repair the circuit and replace electronic components when the dual-burner malfunctions. At the same time, the control circuit board inside the induction cooker is very close to the coil, and the high-frequency magnetic field and high temperature generated when the coil is working will affect the lifespan of the control circuit board and electronic components. Furthermore, when the battery in the gas cooker is depleted or insufficient, the dual-burner must be disassembled to replace the battery, which is an unreasonable structural design. Utility Model Content

[0003] The purpose of this utility model is to provide a gas-induction integrated stove to solve the problems mentioned in the background art. The stove has a box with a detachable cover in the middle of the bottom shell. Electronic components such as the control circuit board and igniter are placed in the box for easy maintenance. The control circuit board is installed far away from the coil to avoid being affected by the coil. At the same time, the power board outputs DC power to supply the igniter, eliminating the original battery power supply structure.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A gas-electromagnetic integrated stove includes a bottom shell with an upper opening, a top cover, an electromagnetic heating device, and a gas burner. The electromagnetic heating device and the gas burner are respectively disposed within the bottom shell. The top cover covers the bottom shell and seals the upper opening of the bottom shell. The electromagnetic heating device includes a coil and a control circuit board. The gas burner includes a burner, a valve assembly, an igniter, and an ignition needle. The bottom shell has a lower opening box in the middle and also includes a removable box cover. The control circuit board and the igniter are respectively disposed within the lower opening box. The box cover covers the lower opening of the box and seals the control circuit board and the igniter.

[0006] The control circuit board is equipped with a DC output terminal, which is connected to the igniter, and the control circuit board provides power to the igniter.

[0007] Furthermore, it also includes a power voltage regulator and a USB interface. The USB interface is located on the outer wall of the casing and is used to connect an external DC power source. When the mains power fails and the gas burner needs to be used, a power bank can be connected via the USB interface to provide power to the igniter 43. The igniter 43 typically has an input voltage of DC 3V or 1.5V, and the power bank has an output voltage of 5V. The power voltage regulator is used to adjust the input DC voltage to the appropriate voltage for the igniter.

[0008] Furthermore, to simplify the circuit design of the control circuit board, the DC output terminal outputs a DC 5V voltage, which is connected to the power supply voltage regulator via a wire. The power supply voltage regulator adjusts the DC voltage input to the control circuit board to the appropriate voltage for the igniter.

[0009] Furthermore, it also includes a cooling fan. The side of the box is provided with an air outlet, the box cover is provided with an air inlet, and the cooling fan is installed inside the box. The cooling fan draws in air through the air inlet, cools the control circuit board, and then discharges it through the air outlet.

[0010] Specifically, the cooling fan is a cross-flow fan, and the air outlet of the cross-flow fan blows air directly towards the finned radiator.

[0011] This utility model provides a gas-induction integrated stove. Because the control circuit board, igniter, and other electronic components are all housed in the same enclosure, repairs are quick and easy by simply removing the enclosure cover in case of a malfunction. Furthermore, the control circuit board has a DC power output terminal connected to the igniter, eliminating the need for a battery-powered system. A USB port is also added for connecting to an external DC power source, solving the emergency need for gas burners during power outages, thus making the stove's structural design more rational.

[0020] like Figures 1 to 5 As shown, a gas-electromagnetic integrated stove includes a bottom shell 1 with an upper opening, a top cover 2, an electromagnetic heating device 3, and a gas burner 4. The electromagnetic heating device 3 and the gas burner 4 are respectively disposed in the cavity of the bottom shell 1, and the top cover 2 covers the upper opening of the bottom shell to seal the bottom shell.

[0021] The electromagnetic heating device 3 includes a coil 31 and a control circuit board 32; the gas burner head 4 includes a burner 41, a valve assembly 42, an igniter 43, and an ignition needle 44.

[0022] The bottom shell 1 has a lower opening box 5 in the middle and also includes a detachable box cover 6. The control circuit board 32 and the igniter 43 are respectively installed in the lower opening box 5. The box cover 6 covers the lower opening of the box 5 to seal the control circuit board 32 and the igniter 43.

[0023] The control circuit board 32 is provided with a DC output terminal 321, which is connected to the igniter 43 through a wire. The control circuit board 32 provides power to the igniter 43, eliminating the original structure of the igniter being powered by a battery.

[0024] Furthermore, it also includes a power voltage regulator 71 and a USB interface 72. The USB interface 72 is located on the outer wall of the housing 5 and is used to connect an external DC power source. When the mains power fails and the gas burner needs to be used, a power bank can be connected via the USB interface 72 to provide power to the igniter 43. The igniter 43 typically has an input voltage of DC 3V or 1.5V, and the power bank has an output voltage of 5V. The power voltage regulator 71 is used to adjust the input DC voltage to the appropriate voltage for the igniter 43.

[0025] Furthermore, in order to simplify the circuit design of the control circuit board 32, the DC output terminal 321 outputs a DC voltage of 5V, which is connected to the power supply voltage regulator 71 through a wire. The power supply voltage regulator adjusts the DC voltage input to the control circuit board to the appropriate voltage of the igniter.

[0026] Furthermore, such as Figure 3 and Figure 4 As shown, it also includes two cooling fans 8. The side of the box body 5 is provided with an air outlet 51, and the box cover 6 is provided with an air inlet 61. The cooling fans 8 are installed inside the box body 5. The cooling fans 8 draw in air through the air inlet 61 and the air-cooled control circuit board 32, and then discharge the air out of the stove body through the air outlet 51.

[0027] Specifically, the cooling fan 8 is a cross-flow fan, and the air outlet of the cross-flow fan blows air directly towards the finned heat sink 9, which effectively improves the heat dissipation effect of the IGBT components on the air-cooled control circuit board 32.

[0028] The principle of this invention is as follows: the control circuit board 32 of the electromagnetic heating device and the igniter 43 of the gas burner are respectively housed in the same box, with a removable cover for easy maintenance in case of malfunction. The control circuit board 32 has a DC power output terminal connected to the igniter 43, eliminating the need for traditional battery power supply and avoiding the problem of insufficient battery voltage leading to ignition difficulties. A USB interface 72 is also added for connecting an external DC power source, solving the emergency need for using the gas burner after a power outage.

[0029] Although the embodiments of this utility model have shown the technical solutions, those skilled in the art can understand that the technical solutions proposed by replacing, modifying or altering these embodiments in combination with conventional technology without departing from the principles and structure of this utility model are substantially the same as those of this utility model.
