Description

Technical Field

[0001] The utility model relates to the technical field of gas rice cookers, in particular to an automatic constant temperature device for a gas rice cooker. Background Art

[0002] A gas rice cooker is a kitchen appliance that uses gas heating to cook rice. The gas rice cooker generates heat by burning gas and transfers the heat to the inner pot, heating the water and rice in the inner pot, thereby cooking the rice. Its temperature control is usually achieved by a mechanical or electronic temperature control device to ensure that the rice is cooked at the appropriate temperature.

[0003] When cooking rice, the temperature control device of the existing gas rice cooker in the prior art is difficult to automatically close the gas valve after the rice is cooked. Since the gas valve cannot be closed automatically, energy may be wasted. If the user fails to find out in time and manually close the gas valve after the rice is cooked, the prolonged gas combustion may cause accidents such as gas leakage and fire, posing a serious threat to people's lives and property safety. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an automatic thermostat for a gas rice cooker, so as to solve the technical problems in the prior art that when cooking rice, the temperature control device inside the existing gas rice cooker is difficult to automatically close the gas valve after the rice is cooked, resulting in poor use effect and greater safety hazards.

[0005] To achieve the above object, the utility model provides the following technical solution: an automatic constant temperature device for a gas rice cooker, comprising a fixed bracket, an induction cup is arranged inside the fixed bracket, wherein a matching induction cover is fixed on the top of the induction cup, and the induction cover and the induction cup are plugged and fixed to each other;

[0006] A fixing base is fixed on the top of the induction cup, and a soft magnetic material is fixed at the center of the fixing base;

[0007] The induction cup is internally connected to a pull rod seat located below the soft magnet, a sliding seat is fixed on the top of the pull rod seat, and a strong magnet that matches the soft magnet is fixed at the center of the top of the sliding seat. A control rod that passes through the bottom of the induction cup is fixed at the center of the bottom of the sliding seat, and the bottom end of the control rod is connected to the gas valve switch of the rice cooker;

[0008] A limit seat is fixed at the bottom end of the fixed bracket, and a plurality of plug-in boards extending into the limit seat are fixed at the bottom of the sensing cup;

[0009] A stabilizing spring is fixed between the top of the fixed bracket and the sensing cup, and the stabilizing spring is located outside the sensing cup.

[0010] By adopting the above technical solution, the utility model is integrally mounted on the top of the gas valve of the gas rice cooker through a fixed bracket. When the gas rice cooker starts to heat up, the gas valve of the rice cooker is in an open state. At the same time, the soft magnet and the strong magnet are attracted and fixed to each other under the action of magnetic force. The magnetic force at this time is greater than the spring elastic force at the rice cooker valve. When the gas temperature reaches the temperature required for cooking the rice, the soft magnet will completely lose magnetism, and the material properties of the soft magnet itself will be transformed into a ceramic state. After the magnetic force disappears, the strong magnet and the soft magnet are separated from each other by the control rod under the reset force of the spring of the control rod, thereby achieving the function of closing the gas valve of the rice cooker and achieving the function of automatically controlling the temperature. This avoids the waste of gas resources and the problem of gas leakage that cannot be closed in time and brings about safety hazards. The overall use effect is good.

[0011] Furthermore, guide pillars penetrating the fixed seat, the sliding seat and the pull rod seat are fixed on both sides of the interior of the sensing cup, and guide holes are opened on both sides of the interior of the fixed seat, the sliding seat and the pull rod seat.

[0012] By adopting the above technical solution, the two groups of guide pillars play a sliding guiding role for the pull rod seat and the sliding seat, and the overall sliding process is more stable.

[0013] Furthermore, support feet are provided on both sides of the bottom of the fixing bracket and the limiting seat, and connection holes are provided inside the support feet.

[0014] By adopting the above technical solution, the utility model as a whole is fixedly connected to the electric rice cooker through the cooperation of the supporting feet and screws of the fixed bracket.

[0015] In summary, the utility model mainly has the following beneficial effects: the utility model is installed as a whole to the top of the gas valve of the gas rice cooker through a fixed bracket. When the gas rice cooker starts to heat up, the gas valve of the rice cooker is in an open state. At the same time, the soft magnetism and the strong magnetism are attracted and fixed to each other under the action of magnetic force. The magnetic force at this time is greater than the spring elastic force at the rice cooker valve. When the gas temperature reaches the temperature required for cooking the rice, the soft magnetism will completely lose magnetism, and the material properties of the soft magnetism itself will be transformed into a ceramic state. After the magnetic force disappears, under the reset force of the spring of the control rod, the strong magnetism and the soft magnetism are driven to separate from each other through the control rod, thereby achieving the effect of closing the gas valve of the rice cooker and achieving the effect of automatic temperature control, avoiding the waste of gas resources and the problem of safety hazards caused by gas leakage due to failure to close the valve in time. The overall use effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0023] The following describes an embodiment of the present invention based on its overall structure.

[0024] An automatic constant temperature device for a gas rice cooker, such as Figure 1-5 As shown, it includes a fixed bracket 1, a sensing cup 2 is arranged inside the fixed bracket 1, wherein a sensing cover 13 that matches with the sensing cup 2 is fixed on the top of the sensing cup 2, and the sensing cover 13 and the sensing cup 2 are plugged and fixed to each other;

[0025] A fixing base 3 is fixed to the top of the induction cup 2, and a soft magnetic material 4 is fixed at the center of the fixing base 3;

[0026] The induction cup 2 is internally slidably connected to a pull rod seat 5 located below the soft magnet 4. A sliding seat 6 is fixed on the top of the pull rod seat 5, and a strong magnet 7 that matches the soft magnet 4 is fixed at the center of the top of the sliding seat 6. A control rod 8 that passes through the bottom of the induction cup 2 is fixed at the center of the bottom of the sliding seat 6, and the bottom end of the control rod 8 is connected to the gas valve switch of the rice cooker;

[0027] When the gas temperature reaches the temperature required for cooking rice (155 degrees), the high temperature is transmitted to the position of the soft magnet 4 through the induction cup 2. At this time, the soft magnet 4 will completely lose its magnetism due to the heat, and the material properties of the soft magnet 4 will be transformed into a ceramic state. After the magnetic force disappears, under the reset force of the spring at the gas valve of the rice cooker, the strong magnet and the soft magnet are separated from each other through the control rod 8, thereby closing the gas valve of the rice cooker and achieving the effect of automatic temperature control, avoiding the waste of gas resources and the problem of gas leakage causing safety hazards due to failure to close the valve in time, and the overall use effect is good;

[0028] A limit seat 9 is fixed to the bottom end of the fixed bracket 1, and multiple groups of plug-in boards 14 extending into the limit seat 9 are fixed to the bottom of the sensing cup 2. The plug-in boards 14 facilitate the limit seat 9 to support and fix the sensing cup 2, further improving the connection effect of the sensing cup 2.

[0029] A stabilizing spring 15 is fixed between the top of the fixing bracket 1 and the sensing cup 2 , and the stabilizing spring 15 is located outside the sensing cup 2 , wherein the stabilizing spring 15 makes the connection between the fixing bracket 1 and the sensing cup 2 more stable.

[0030] See also Figure 1 、 Figure 2 and Figure 4 Guide pillars 10 that pass through the fixed seat 3, the sliding seat 6 and the pull rod seat 5 are fixed on both sides of the inside of the sensing cup 2, and guide holes are opened on both sides of the fixed seat 3, the sliding seat 6 and the pull rod seat 5. The utility model sets the above structure, in which the two groups of guide pillars 10 play a sliding guiding role for the pull rod seat 5 and the sliding seat 6, and the overall sliding process is more stable.

[0031] See also Figure 1 、 Figure 2 、 Figure 4 and Figure 5 The fixing bracket 1 and the limiting seat 9 are both provided with supporting feet 11 on both sides of the bottom, and the supporting feet 11 are provided with connecting holes 12. By setting the above structure, the utility model is fixedly connected to the rice cooker as a whole through the cooperation of the supporting feet 11 of the fixing bracket 1 and the screws.

[0032] The working principle of the utility model is as follows: when in use, the utility model is installed as a whole to the top of the gas valve of the gas rice cooker through the fixing bracket 1. Specifically, the utility model is fixedly connected to the rice cooker as a whole through the cooperation of the supporting feet 11 of the fixing bracket 1 and the screws;

[0033] When the gas rice cooker starts heating, the gas valve of the rice cooker is in the open state. At the same time, the soft magnet 4 and the strong magnet 7 are attracted and fixed to each other under the action of the magnetic force. The magnetic force at this time is greater than the spring force at the rice cooker valve.

[0034] When the gas temperature reaches the temperature required for cooking rice (155 degrees), the high temperature is transmitted to the position of the soft magnet 4 through the induction cup 2. At this time, the soft magnet 4 will completely lose its magnetism due to the heat, and the material properties of the soft magnet 4 will be transformed into a ceramic state. After the magnetic force disappears, the control rod 8 drives the strong magnet and the soft magnet to separate from each other under the reset force of the spring. At this time, the gas valve of the rice cooker is closed, achieving the effect of automatic temperature control, avoiding the waste of gas resources and the problem of gas leakage causing safety hazards due to failure to close the valve in time, and the overall use effect is good;

[0035] Furthermore, when the soft magnet 4 loses its magnetism, under the action of the control rod 8, the pull rod seat 5, the sliding seat 6 and the strong magnet 7 slide down inside the induction cup 2, and the two sets of guide pillars 10 serve as sliding guides for the pull rod seat 5 and the sliding seat 6, making the overall sliding process more stable.

[0036] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
