Description

Technical Field

[0001] The present invention belongs to the technical field of gas stoves, and particularly relates to a gas stove regulating valve and a gas stove. Background Art

[0002] Gas stoves are essential kitchen appliances in modern kitchens. During the cooking process, different dishes have different requirements for heating power. For example, stir-frying requires high and intense heat, soup-making requires low heat, and pancake-making requires even heat. Even during the cooking of a single dish, multiple different cooking powers may be needed. Currently, most gas stoves on the market have two-ring flames. When users use them, they first rotate counterclockwise by 90 degrees to achieve maximum-fire ignition. Continuing to rotate counterclockwise can achieve the adjustment of the flame from maximum to minimum. During the process of the flame decreasing from large to small, first, the outer-ring flame starts to decrease until the outer-ring flame goes out. During this process, the size of the inner-ring flame remains unchanged. Only after that does the inner-ring flame start to decrease until the minimum fire.

[0003] Chinese cooking is diverse. The above-mentioned way of gradually adjusting the outer and inner-ring flames can only meet some cooking needs. For example, cooking methods such as pancake-making require the synchronous adjustment of the inner and outer rings during the flame adjustment process to ensure the uniform change of the flame. However, either the gradual adjustment of the outer and inner-ring flames alone or the synchronous adjustment can only meet some cooking requirements, and the applicability is not wide. Further improvement is needed to simultaneously achieve the gradual adjustment and synchronous adjustment of the flame, and even a multi-mode gas regulating valve with more adjustment methods. Summary of the Invention

[0004] In order to overcome the deficiencies existing in the above-mentioned prior art, the main purpose of the present invention is to provide a gas stove regulating valve and a gas stove, which can not only gradually adjust the outer-ring firepower and inner-ring firepower of the gas stove, but also synchronously adjust the outer-ring firepower and inner-ring firepower to meet diverse cooking needs.

[0005] To achieve the above purpose, the present invention first provides a gas stove regulating valve, which is arranged on the gas stove body and includes a first regulating valve assembly, a second regulating valve assembly, and a knob assembly. The first regulating valve assembly and the second regulating valve assembly respectively have a first regulating cavity and a second regulating cavity. The knob assembly has a control cavity. The first regulating cavity, the second regulating cavity, and the control cavity are communicated with the air inlet channel. The knob assembly rotates in one direction to control the first regulating valve assembly, so as to gradually adjust the inner and outer-ring flames of the gas stove; the knob assembly rotates in the other direction to control the second regulating valve assembly, so as to synchronously adjust the inner and outer-ring flames of the gas stove.

[0006] Further, the first regulating valve assembly includes a first valve core and a first regulator that can cooperate with the knob assembly to control the rotation of the first valve core. The first valve core is placed in the first regulating cavity, and the first regulating cavity is provided with a first inner-ring fire outlet hole and a first outer-ring fire outlet hole, and the first inner-ring fire outlet hole and the first outer-ring fire outlet hole are communicated with the air inlet channel; the second regulating valve assembly includes a second valve core and a second regulator that can cooperate with the knob assembly to control the rotation of the second valve core.

The lower end of the valve rod is inserted into the control cavity, and the knob gear is fixed on the valve rod. By pressing the valve rod, the knob gear is engaged with the first gear regulator or the second gear regulator.

[0009] Further, the knob assembly further includes a reset member, and the reset member is sleeved on the valve rod.

[0010] Further, the valve rod has two-stage pressing. The first stage of pressing makes the knob gear engaged with the first gear regulator, and the second stage of pressing makes the knob gear engaged with the second gear regulator. The valve rod can be in a state of no pressing, the first stage of pressing or the second stage of pressing through the reset member.

[0011] Further, when the valve rod is pressed in the first stage, it is fixed at the first buckle provided in the control cavity, and when the valve rod is pressed in the second stage, it is fixed at the second buckle provided in the control cavity.

[0012] Further, the control cavity is provided with a Hall switch, and the Hall switch is connected to the knob assembly. When the knob assembly is operated, the Hall switch sends an ignition signal to the gas stove controller to control ignition.

[0013] Further, the gas stove regulating valve further includes an outer-ring fire outlet airway interface and an inner-ring fire outlet airway interface.

[0019] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] Embodiment 1:

[0021] As Figure 1 and 2 shown, Embodiment 1 of the present invention provides a gas stove regulating valve, which includes a first regulating valve assembly 1, a second regulating valve assembly 2 and a knob assembly 3. The first regulating valve assembly 1 and the second regulating valve assembly respectively have a first regulating chamber and a second regulating chamber. The knob assembly 3 has a control chamber 4. The lower end of the knob assembly 5 is inserted into the control chamber 4. The present invention also has an air inlet channel 5, an outer-ring fire air channel interface 6 and an inner-ring fire air channel interface 7. The first regulating chamber, the second regulating chamber and the control chamber 4 are communicated with the air inlet channel 5.

[0022] With the above structure, when the knob assembly 3 rotates in one direction, it controls the first regulating valve assembly 1. First, it controls the gas flow rate through the air inlet channel 5 into the outer-ring fire air channel interface 6, and then controls the gas flow rate of the inner-ring fire air channel interface 7, so that the inner and outer-ring flames of the gas stove are adjusted step by step; when the knob assembly 3 rotates in the other direction, it controls the second regulating valve assembly 2, and then synchronously controls the gas flow rates through the air inlet channel 5 into the outer-ring fire air channel interface 6 and the inner-ring fire air channel interface 7, so that the inner and outer-ring flames of the gas stove are adjusted synchronously. Such a structure of a single valve body with two regulating chambers realizes that one regulating valve can not only synchronously control the firepower sizes of the inner and outer rings, but also gradually control the firepower size from the outer ring to the inner ring.

[0023] The first regulating valve assembly 1 includes a first valve core 11 and a first gear regulator 12. The first valve core 11 is arranged in a first regulating cavity. The first regulating cavity is also provided with an inner-ring flame outlet hole 13 and an outer-ring flame outlet hole 14. The inner-ring flame outlet hole 13 and the outer-ring flame outlet hole 14 are communicated with an air inlet passage 5. The first gear regulator 12 is installed at the upper end of the first valve core 11. The first gear regulator 12 controls the rotation of the first valve core 11, so that the gas in the air inlet passage 5 enters the outer-ring flame outlet airway interface 6 and the inner-ring flame outlet airway interface 7 through the outer-ring flame outlet hole 14 and the inner-ring flame outlet hole 13, and the flow rate is adjusted step by step.

[0024] The second regulating valve assembly 2 includes a second valve core 21, a second gear regulator 22. The second valve core 21 is arranged in a second regulating cavity. The second regulating cavity is also provided with an inner-ring flame outlet hole 23 and an outer-ring flame outlet hole 24. The inner-ring flame outlet hole 23 and the outer-ring flame outlet hole 24 are communicated with the air inlet passage 5. The second gear regulator 22 is installed at the upper end of the second valve core 21. The second gear regulator 22 controls the rotation of the second valve core 21, so that the gas in the air inlet passage 5 enters the outer-ring flame outlet airway interface 6 and the inner-ring flame outlet airway interface 7 through the outer-ring flame outlet hole 24 and the inner-ring flame outlet hole 23, and the flow rate is adjusted synchronously.

[0025] The first gear regulator 12 and the second gear regulator 22 are arranged in a staggered manner, so that when one of them rotates, it will not affect the other.

[0026] The knob assembly 3 includes a valve rod 31, a knob gear 32 and a reset member 33. The valve rod 31 is inserted into a control cavity 4. The reset member 33 is sleeved on the valve rod 31. The knob gear 32 is fixed at the upper end of the valve rod 31. The valve rod 31 has a two-stage press. The first press makes the knob gear 32 engage with the first gear regulator 12. At the same time, the valve rod 31 is fixed at a first buckle (not shown) in the control cavity. Then the second press makes the knob gear 32 engage with the second gear regulator 22. At the same time, the valve rod 31 is fixed at a second buckle (not shown) in the control cavity. When the valve rod 31 is pressed downward, the valve rod 31 can disengage from the buckle, and then return to the initial position through the reset member 33, so that the knob gear 32 disengages from both the first gear regulator 12 and the second gear regulator 22.

[0027] As Figure 3 shown, the control cavity 4 is provided with a Hall switch 8. The Hall switch 8 is connected to the knob assembly 3. When the knob assembly 3 is operated, the Hall switch 8 sends an ignition signal to the gas stove controller to control ignition.

[0028] The specific working principle is as follows;

[0029] In use, press the first section of the valve stem 31 to engage the knob gear 32 with the first gear regulator 12, then rotate the knob gear 32 counterclockwise by 90°, and then drive the first gear regulator 12 to rotate clockwise by 90°, thereby driving the first valve core 11 to rotate. Gas passes from the intake passage 5 through the specially designed vent holes on the first valve core 11. The gas enters the inner-ring fire outlet holes 13 and the outer-ring fire outlet holes 14 to supply gas to the gas stove. At the same time, the Hall switch 8 sends an ignition signal to the gas stove controller for ignition. After ignition, it can continue to rotate counterclockwise. When the first valve core 11 rotates, the size of the vent hole leading to the outer-ring fire outlet holes 14 changes, and then the gas flow rate into the outer-ring fire outlet holes 14 is controlled. When rotated to a certain angle, the vent hole leading to the outer-ring fire outlet holes 14 is completely closed, and the outer-ring fire decreases until it goes out. Continuing to rotate the knob gear 32 counterclockwise starts to reduce the vent hole leading to the inner-ring fire outlet holes 13, thereby reducing the gas flow rate of the inner-ring fire outlet holes 13, and the inner-ring fire starts to become smaller; if the firepower needs to be adjusted back, the knob gear 32 can be rotated clockwise again. The first valve core 11 rotates, and the vent hole leading to the inner-ring fire outlet holes 13 becomes larger, and the inner-ring fire starts to become larger. When rotated to a certain angle, the vent hole leading to the outer-ring fire outlet holes 14 opens, and then the outer-ring fire is reignited.

[0030] When synchronous adjustment of the inner and outer ring flames is required, the second section of the valve stem 31 can be pressed to engage the knob gear 32 with the second gear regulator 22, then rotate the knob gear 32 clockwise by 90°, and then drive the second gear regulator 22 to rotate counterclockwise by 90°, thereby driving the second valve core 21 to rotate. Gas passes from the intake passage 5 through the specially designed vent holes on the second valve core 21 and supplies gas to the gas stove from the inner-ring fire outlet holes 23 and the outer-ring fire outlet holes 24. At the same time, the Hall switch 8 sends an ignition signal to the gas stove controller for ignition. After ignition, it can continue to rotate clockwise. At this time, the second valve core 21 rotates, and the vent holes leading to the outer-ring fire outlet holes 24 and the inner-ring fire outlet holes 23 become smaller synchronously, and then the gas flow rates of the outer-ring fire outlet holes 24 and the inner-ring fire outlet holes 23 become smaller synchronously, and the inner and outer ring flames become smaller synchronously; if the firepower needs to be adjusted back, the knob gear 32 can be rotated counterclockwise again. The second valve core 21 rotates, and the vent holes leading to the outer-ring fire outlet holes 24 and the inner-ring fire outlet holes 23 become larger synchronously, and the gas flow rates of the outer-ring fire outlet holes 24 and the inner-ring fire outlet holes 23 become larger synchronously, and the inner and outer ring flames become larger synchronously.

The two-way adjustment cock valve is installed on the gas stove body. The gas stove is provided with a gas pipeline, an inner-ring air outlet passage, and an outer-ring air outlet passage, which are respectively connected to the intake passage 5, the inner-ring fire air outlet passage interface 7, and the outer-ring fire air outlet passage interface 6 of the two-way adjustment cock valve.

[0033] The gas stove provided by this embodiment realizes the synchronous control of the inner and outer ring firepower and the step-by-step control of the outer ring firepower to the inner ring firepower through the above-mentioned two-way regulating cock, meeting the diverse cooking requirements for different firepower.
