[0053] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to numbers and / or letters in different examples, and such repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those skilled in the art can realize the application of other processes and / or the use of other materials.
[0054] In the first aspect, in combination Figures 1 to 10 As shown in the drawings, the present application provides a stove, which comprises a panel 5, a liquid container 6, a burner 7, an ignition needle 8, a thermocouple 4 and a fire cover assembly.
[0055] In combination Figure 1and Figure 9 As shown in FIG. 1, the liquid receiving tray 6 is fixedly arranged on the panel 5, and a mounting hole is formed in the center of the liquid receiving tray 6. The upper end of the burner 7 extends above the liquid receiving tray 6 through the mounting hole, and the burner 7 is fixedly connected with the liquid receiving tray 6 by bolts.
[0056] The burner 7 is the core component of the stove. The burner 7 is used to introduce air and disperse fuel gas, so that the air and the fuel gas are mixed and then burned to generate a flame. The ignition needle 8 and the thermocouple 4 are installed on the burner 7.
[0057] The working principle of the ignition needle 8 is based on high-voltage arc or spark to ignite fuel gas. The specific process is as follows: when the knob on the stove is pressed, the micro switch is closed, the ignition pulse works, high-frequency voltage is generated, the voltage is raised to high voltage by the step-up transformer, and the high voltage is discharged to the burner through the tip of the ignition needle 8 to generate a spark, thereby igniting the fuel gas.
[0058] When the thermocouple 4 works, it converts the temperature of the flame into a small electric signal by using the thermoelectric effect. When the flame burns, the thermocouple 4 generates an electromotive force due to heat, and the electromotive force is transmitted to the electromagnetic valve to keep it open, allowing fuel gas to pass through and continue to burn. When the flame is extinguished or the temperature decreases to a certain extent, the temperature of the thermocouple 4 decreases rapidly, the electromotive force disappears, and the electromagnetic valve is immediately closed, cutting off the fuel gas supply and avoiding fuel gas leakage, thereby protecting the personal safety of the user.
[0059] In a second aspect, in combination with Figure 8 and Figure 9 As shown in FIG. 1, the fire cover assembly is installed above the burner 7, and its main function is to disperse and guide the fuel gas to ensure that the burning flame can be evenly and stably distributed in the cooking area.
[0060] The fire cover assembly includes a fire cover seat 1 and an inner ring fire cover 2. The fire cover seat 1 is fixed above the burner 7, and a thermocouple hole 11 is formed in the fire cover seat 1, which is configured for the thermocouple 4 to pass through.
[0061] In combination with Figure 2 , Figure 3 and Figure 5 As shown in FIG. 1, the inner ring fire cover 2 is arranged at the center above the fire cover seat 1, and a gas mixing chamber 26 is formed in the bottom of the inner ring fire cover 2, in which the mixing of fuel gas and air is performed. The upper surface of the inner ring fire cover 2 extends upward to form a brim 21, and the brim 21 is located at the edge of the upper surface of the inner ring fire cover 2.
[0062] In combination with Figure 2 As shown in FIG. 1, the brim 21 and the upper surface of the inner ring fire cover 2 enclose a receiving portion 22, which is used to receive the liquid overflow from the bottom of the pot.
[0063] The edge of the inner ring fire cover 2 is formed with a flow guide part 23 above the thermocouple hole 11, and the flow guide part 23 is in communication with the receiving part 22.
[0064] As shown in the combination Figure 7 The flow guide part 23 is configured to shield the thermocouple 4 and guide the pot bottom overflow liquid in the receiving part 22 out of the outside of the receiving part 22.
[0065] Specifically, by setting the fire cover seat 1 and the inner ring fire cover 2, the fire cover seat 1 is formed with the thermocouple hole 11; the upper surface of the inner ring fire cover 2 is upwardly extended to form a brim 21, and the brim 21 and the upper surface of the inner ring fire cover 2 enclose to form the receiving part 22, which is used to receive the pot bottom overflow liquid and avoid the pot bottom overflow liquid from dripping around the upper surface of the inner ring fire cover 2 to block the fire hole 25 on the inner ring fire cover 2; the edge of the inner ring fire cover 2 is formed with the flow guide part 23 above the thermocouple hole 11, and the flow guide part 23 is in communication with the receiving part 22, and the flow guide part 23 is used to shield the thermocouple 4 and guide the pot bottom overflow liquid in the receiving part 22 out of the outside of the receiving part 22, so as to avoid the pot bottom overflow liquid from polluting the thermocouple 4 and improve the ignition success rate.
[0066] Specifically, the flow guide part 23 is in a groove structure, and the combination Figure 6 and Figure 7 As shown in the combination, the flow guide part 23 extends to the outside of the receiving part 22, and after installation is completed, the flow guide part 23 is located directly above the thermocouple 4 and completely covers the thermocouple 4 in the vertical direction, so as to avoid the pot bottom overflow liquid from polluting the thermocouple 4.
[0067] In some embodiments of the present application, the combination Figure 4 As shown in the combination, the bottom wall of the receiving part 22 is higher than the bottom wall of the flow guide part 23, and the bottom wall at the connection between the flow guide part 23 and the receiving part 22 is downwardly inclined.
[0068] Specifically, by setting the bottom wall of the receiving part 22 to be higher than the bottom wall of the flow guide part 23, a height difference is formed between the receiving part 22 and the flow guide part 23, and the pot bottom overflow liquid entering the receiving part 22 flows to the flow guide part 23 by using the principle that water flows downward, so as to facilitate the pot bottom overflow liquid to be guided out by the flow guide part 23.
[0069] By setting the bottom wall at the connection between the flow guide part 23 and the receiving part 22 to be downwardly inclined, that is, the connection is inclined toward the flow guide part 23 which is at a lower position, so as to facilitate the pot bottom overflow liquid to flow forward.
[0070] In some embodiments of the present application, the inner wall surface of the brim 21 is inclined.
[0071] Specifically, by setting the inner wall surface of the brim 21 to be inclined, the pot bottom overflow liquid on the brim 21 flows into the receiving part 22 as much as possible, so as to avoid the receiving part from forming a dead angle.
[0072] In some embodiments of the present application, one of the inner ring fire cap 2 and the fire cap seat 1 is formed with a protruding portion 24, and the other is formed with a recessed portion 12, and the protruding portion 24 extends into the recessed portion 12 to fix the position of the inner ring fire cap 2 on the fire cap seat 1.
[0073] Specifically, by providing the protruding portion 24 on one of the inner ring fire cap 2 and the fire cap seat 1, and the recessed portion 12 on the other, the protruding portion 24 extends into the recessed portion 12 to achieve the positioning of the inner ring fire cap 2 on the fire cap seat 1, avoiding displacement of the inner ring fire cap 2.
[0074] For example, the protruding portion 24 is provided on the bottom of the inner ring fire cap 2, and the recessed portion 12 is provided on the fire cap seat 1, and the positions of the protruding portion 24 and the recessed portion 12 correspond.
[0075] In some embodiments of the present application, in combination with Figure 6 As shown, the thermocouple hole 11 is in a long strip-shaped hole structure, and the length direction of the thermocouple hole 11 is consistent with the installation direction of the thermocouple 4.
[0076] Specifically, the thermocouple hole 11 is in a long strip-shaped hole structure, and the length direction of the thermocouple hole 11 is consistent with the installation direction of the thermocouple 4, so that when the installation of the thermocouple 4 is skewed, interference between the thermocouple 4 and the fire cap seat 1 is avoided.
[0077] For example, in combination with the figure shown, the thermocouple 4 is fastened towards the center direction of the fire cap seat 1 by a bolt or other fastener.
[0078] During the fastening process, the thermocouple 4 is prone to skew along the fixed direction of the screw. If the diameter of the thermocouple hole 11 is too large, it will result in too large an ignition distance, that is, the larger the diameter of the thermocouple hole 11, the larger the fitting gap with the fire cap seat 1, which will directly reduce the success rate of ignition; if the diameter of the thermocouple hole 11 is too small, that is, the fitting gap with the fire cap seat 1 is too small, it is easy to cause interference between the thermocouple 4 and the fire cap seat 1 during assembly, resulting in difficulty in installation and disassembly of the fire cap seat 1 and failure to be in place, thereby causing a gap between the fire cap seat 1 and the burner head 7, resulting in gas leakage.
[0079] By setting the thermocouple hole 11 in a long strip structure, the thermocouple 4 can be skewed within a certain area to facilitate installation and disassembly.
[0080] It can be understood that when the installation direction of the thermocouple 4 and the connecting line direction of the thermocouple hole 11 and the fire cap seat 11 are perpendicular, the length direction of the thermocouple hole 11 is also perpendicular to the connecting line direction of the thermocouple hole 11 and the fire cap seat 11.
[0081] In some embodiments of the present application, the side wall of the inner ring fire cover 2 is formed with a fire hole 25 in the circumferential direction, and the flow guide part 23 is located above the fire hole 25.
[0082] Specifically, by arranging the flow guide part 23 above the fire hole 25 on the inner ring fire cover 2, the pot bottom overflow can be discharged through the flow guide part 23, avoiding the pot bottom overflow overflowing along the circumference of the inner ring fire cover 2, so that the pot bottom overflow can be reduced. The fire hole 25 is blocked.
[0083] In some embodiments of the present application, in combination Figure 7 As shown, the fire cover seat 1 is formed with a liquid accumulation disc 13, and the liquid accumulation disc 13 is configured to collect the pot bottom overflow discharged by the flow guide part 23.
[0084] Specifically, by arranging the liquid accumulation disc 13 on the fire cover seat 1, the liquid accumulation disc 13 is used to collect the pot bottom overflow discharged by the flow guide part 23, preventing the pot bottom overflow from contaminating the panel 5, and facilitating cleaning of dirt.
[0085] Specifically, the liquid accumulation disc 13 is in a disc structure, and the liquid accumulation disc 13 is annularly arranged at the lower portion of the fire cover seat 1.
[0086] In some embodiments of the present application, the fire cover seat 1 is formed with an open slot 14 at a position corresponding to the thermocouple hole 11, the open slot 14 is open towards the edge and upper portion of the fire cover seat 1, and the bottom wall of the open slot 14 is inclinedly arranged towards the liquid accumulation disc 13.
[0087] Specifically, by forming the open slot 14 on the fire cover seat 1 at a position corresponding to the thermocouple hole 11, the open slot 14 is open towards the edge and upper portion of the fire cover seat 1, on the one hand, facilitating the thermocouple 4 to pass through the thermocouple hole 11, and on the other hand, the bottom wall of the open slot 14 is inclinedly arranged towards the liquid accumulation disc 13, so that the pot bottom overflow dripping from the flow guide part 23 can flow into the liquid accumulation disc 13 along the open slot 14.
[0088] In some embodiments of the present application, in combination Figure 8 As shown, the fire cover assembly further comprises an outer ring fire cover 3.
[0089] The outer ring fire cover 3 is arranged on the fire cover seat 1 and annularly arranged outside the inner ring fire cover 2, and the liquid accumulation disc 13 is located below the outer ring fire cover 3.
[0090] Specifically, by arranging the liquid accumulation disc 13 below the outer ring fire cover 3, interference of the liquid accumulation disc 13 to the outer ring fire cover 3 can be avoided.
