Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to an anti-dry burning energy-saving valve integrated structure and a gas cooker. Background Art

[0002] Gas stoves have been widely used in people's daily lives, but the existing gas stoves cannot achieve low heat when the pot is away and high heat when the pot is in use. This inevitably leads to gas waste when people change or wash pots, resulting in a waste of resources. Existing energy-saving stoves that are away from the pot usually use electronic sensing, such as gravity sensors to calculate the gravity changes on the pot rack to sense whether the pot exists. This structure has a short service life, a high failure rate, and high production and after-sales costs.

[0003] To this end, the prior art has designed an energy-saving valve structure that uses a mechanical drive valve stem structure to adjust the burner gas with a mechanical structure. For example, patent No. CN202020681020.0 discloses a gas energy-saving valve. Existing gas stove products pursue the design requirements for the anti-dry burning function. Usually, an anti-dry burning probe is designed in the middle of the burner. The temperature at the bottom of the pot is adapted and the temperature is detected by using the temperature sensing probe that can be flexibly moved up and down to achieve the purpose of anti-dry burning. The market is looking for a product that has energy saving and emission reduction and can also perform anti-dry burning functions. If the elastic and retractable anti-dry burning structure of the prior art is directly added to the burner, it requires additional layout space and is difficult to directly match with the energy-saving valve. In order to simplify the burner structure and enable the burner to have both the functions of an energy-saving valve and anti-dry burning, further improvements are needed. Utility Model Content

[0029] Example

[0030] Reference Figures 1 to 3 The utility model proposes an integrated structure of an anti-dry burning energy-saving valve, comprising: a longitudinal rod 10, a valve body 20, a valve stem 30 and a temperature sensing probe 40;

[0031] The valve body 20 has an air inlet channel 21 and an air outlet channel 22 ; the valve stem 30 is arranged on the valve body 20 for opening or closing the air outlet channel 22 ; the longitudinal rod 10 can be elastically extended and retracted up and down; a temperature sensing probe 40 is arranged at the top of the longitudinal rod 10 .

[0032] In the utility model, the energy-saving valve is arranged below the burner, and the longitudinal rod 10 can be movably arranged in the middle of the burner. When the pot is placed above the burner, the longitudinal rod 10 can be pressed down; when the pot leaves the burner, the longitudinal rod 10 can be reset upward; the air inlet channel 21 is connected to the air inlet pipe of the gas stove, and the air outlet channel 22 is connected to the outer ring air inlet end of the burner. By blocking the air outlet channel 22, the gas supply of the outer ring air inlet end of the burner or part of the gas path can be closed. A temperature probe 40 is arranged at the top of the longitudinal rod 10. The temperature probe 40 can feed back the bottom temperature information of the pot used to the ignition pulse control device or the electric control center. When the temperature information of the temperature probe 40 is lower than the set value, the burner works normally; when the temperature information of the temperature probe 40 is higher than the set value, the burner can be controlled to stop working to avoid dry burning and achieve the effect of preventing dry burning. The utility model provides a temperature sensing probe 40 at the upper end of the longitudinal rod 10, so that when the cooker leaves the burner, the energy-saving valve is linked to control the switching of the outer ring gas supply; when the cooker presses down the longitudinal rod 10, the temperature of the cooker can be monitored, thereby realizing an integrated multifunctional control effect of over-temperature and dry-burn prevention.

[0033] In this embodiment, a vertically extending wire passage 11 is provided inside the longitudinal rod 10, and the wire harness of the temperature sensing probe 40 can be passed through the wire passage 11. By using the vertically extending wire passage 11 that passes through the interior of the longitudinal rod 10, the wire harness of the temperature sensing probe 40 can be conveniently arranged and protected, thereby reducing the risk of being damaged by the flame of the burner and the temperature sensing environment.

[0034] Specifically, in order to improve the heat insulation protection effect of the wire harness in the wire passage 11, the wire passage 11 is filled with a heat insulation medium such as heat insulation cotton.

[0035] In other embodiments, the wiring harness of the temperature sensing probe 40 may also be passed through the outer side of the longitudinal rod 10 , or may be wound around the outer side of the longitudinal rod 10 .

[0036] In some embodiments, a cap-shaped portion 12 is provided at the top of the longitudinal rod 10. For example, a detachable disc-shaped nut structure can expand the effective contact surface between the top of the longitudinal rod 10 and the cookware, and the longitudinal rod 10 is not prone to tilting and swinging, which reduces the phenomenon of misalignment and stagnation, and improves the stability of the vertical movement of the longitudinal rod 10. It is also convenient to install and lock the temperature probe 40 on the top of the longitudinal rod 10 from above.

[0037] In some embodiments, the outer edge of the cap-shaped portion 12 extends downward with a shield, which can suppress the flame and direct the flame away from the temperature sensing probe 40, thereby reducing the impact of the flame and the high temperature generated by the flame on the temperature sensing probe 40 and improving the temperature measurement accuracy of the temperature sensing probe 40.

[0038] In this embodiment, in order to enable the vertical extension and contraction of the longitudinal rod 10 to drive the extension and contraction of the valve stem 30 , a rotating block 50 is further provided between the bottom end of the longitudinal rod 10 and the valve stem 30 .

[0039] In this embodiment, the valve body 20 is provided with a connection seat 23, and a connection sleeve 24 is provided on the connection seat 23; the longitudinal rod 10 is telescopically arranged in the connection seat 23 and the connection sleeve 24; the valve stem 30 is provided with a first return spring 13, and the first return spring 13 is arranged in the connection sleeve 24. The first return spring 13 can be conveniently installed by using the structure of the connection sleeve 24.

[0040] Specifically, the longitudinal rod 10 is provided with an annular groove 15 for installing the snap ring 14; the upper end of the first return spring 13 can abut against the snap ring 14. The lower end of the first return spring 13 abuts against the connecting seat 23, and the upper end abuts against the snap ring 14, thereby providing elastic force for the longitudinal rod 10 to return upward. During the process of pressing down the connecting sleeve 24, the connecting snap ring 14 can be abutted against and installed, and the installation of the first return spring 13 is completed.

[0041] In some embodiments, a longitudinal extension sleeve 25 is provided above the connection sleeve 24, and the longitudinal rod 10 is penetrated by the longitudinal extension sleeve 25. The height of the limit hole at the upper end of the longitudinal rod 10 raised by the longitudinal extension sleeve 25 reduces the exposed length of the upper end of the longitudinal rod 10, which can effectively reduce the shaking amplitude of the longitudinal rod 10 when the longitudinal rod 10 moves up and down, and improve the stability of the movement of the longitudinal rod 10. At the same time, the travel installation height of the first return spring 13 is also raised, and a longer spring can be installed, thereby matching more types of springs, facilitating adaptation to improve the smoothness of the movement of the longitudinal rod 10 and improve the comfort of operation.

[0042] In some embodiments, in order to facilitate the downward pressing and installation of the first return spring 13, the connecting sleeve 24 is in a truncated cone-shaped structure that gradually narrows from bottom to top.

[0043] The utility model also provides another technical solution: a gas cooker, comprising the above-mentioned anti-dry burning energy-saving valve integrated structure.

[0044] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
