Description

Technical Field

[0001] The utility model relates to the technical field of gas stoves, in particular to a gas stove capable of accurately starting a stir-frying function. Background Art

[0002] With the improvement of material living standards, people have higher and higher requirements for the heat load of stoves. The high-fire mode of traditional stoves can no longer meet the needs of users for stir-frying. For this reason, the prior art has also designed stoves with a one-button stir-frying function. When the user activates the stir-frying function, the firepower of the stove will increase significantly to meet the user's needs for stir-frying.

[0003] For example, the Chinese invention patent with publication number CN107514656A discloses a method for controlling instantaneous ignition and instantaneous high fire of a stove, which requires the cooperation of a pressure plate and two micro switches to achieve instantaneous high fire. The Chinese invention patent with publication number CN115654539A discloses a method for controlling stir-frying of a gas stove. In this patent document, it uses an angle detection part and a micro switch to jointly control stir-frying. The on-off of the micro switch has a certain stroke, and switching to the plug valve will produce an angle deviation of about 30 degrees. The gas channels of the valve core air outlet within this range are different, resulting in a large deviation in the heat load of stir-frying. In addition, when the stroke of the micro switch fails, it cannot determine whether the control valve is in the stir-frying position. When the control valve of the stove is screwed to the stir-frying position, the stir-frying function may not be triggered, which undoubtedly reduces the user experience. Utility Model Content

[0004] The utility model provides a gas stove capable of accurately starting a stir-frying function, which can accurately locate the stir-frying position, ensure the heat load accuracy of the stir-frying, and avoid the situation where the stir-frying function fails to start.

[0005] In order to solve the above problems, the utility model adopts the following technical solutions:

[0006] An embodiment of the utility model provides a gas stove that can accurately activate the stir-fry function, comprising a control valve, a controller, a positioning device, a contact switch and an auxiliary stir-fry component; the control valve comprises a valve seat and a valve stem arranged on the valve seat, the positioning device is arranged on the valve seat and is used to detect the angle of the valve stem, the contact switch is arranged on the valve seat, a pressing piece is fixed on the valve stem, and when the valve stem is rotated to a preset stir-fry angle, the pressing piece is located above the contact switch; the positioning device, the contact switch and the auxiliary stir-fry component are all connected to the controller, and when the positioning device detects that the valve stem is at the preset stir-fry angle and the contact switch is triggered, the controller controls the auxiliary stir-fry component to start working.

[0007] In some embodiments, a power switch is also provided on the valve seat. When the valve stem rotates to a preset shutdown angle, the power switch is in an off position. When the valve stem rotates away from the preset shutdown angle, the power switch is in an on position.

[0008] In some embodiments, the positioning device is a potentiometer, an encoder or an infrared sensor.

[0009] The utility model has at least the following beneficial effects: a positioning device and a contact switch are arranged on the valve seat of the utility model; the positioning device can detect the angle of the valve stem; a pressure plate is fixed on the valve stem; only when the valve stem is rotated to a preset stir-frying angle, the pressure plate is located above the contact switch, and the user can trigger the contact switch; when the positioning device detects that the valve stem is at the preset stir-frying angle and the contact switch is triggered, the controller controls the auxiliary stir-frying component to start working; since the positioning device can accurately detect the angle of the valve stem, there will be no large angle deviation of the micro switch, so that the stir-frying position can be accurately located to ensure the accuracy of the stir-frying heat load; at the same time, compared with the travel switch, the contact switch is more reliable; when the valve stem is at the stir-frying angle and the user presses and triggers the contact switch, the stir-frying function is started, avoiding the situation where the stir-frying function is not started.

[0020] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0021] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0022] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0023] The embodiment of the utility model provides a gas stove which can accurately start the stir-frying function. Figure 1 and Figure 2As shown, it includes a control valve, a controller 200, a positioning device 300, a contact switch 400 and an auxiliary stir-frying component 500. The control valve includes a valve seat 110 and a valve stem 120 arranged on the valve seat 110. The valve stem 120 can rotate relative to the valve seat 110 and can also move along the axial direction of the valve stem 120 relative to the valve seat 110. The user turns the valve stem 120 to start the fire, adjust the fire power and control the fire. The positioning device 300 is arranged on the valve seat 110 and is used to detect the angle of the valve stem 120 relative to the valve seat 110. The contact switch 400 is arranged on the valve seat 110. A pressing plate 130 is fixed on the valve stem 120. The pressing plate 130 is linked with the valve stem 120. When the valve stem 120 rotates, the pressing plate 130 rotates synchronously. When the valve stem 120 moves along its axial direction, the pressing plate 130 also moves along the axial direction of the valve stem 120. The positions of the contact switch 400 and the pressing plate 130 are configured such that when the valve stem 120 rotates to a preset stir-fry angle, the pressing plate 130 is located above the contact switch 400. When the valve stem 120 rotates to a preset stir-fry angle, it indicates that the user wishes to start the stir-fry function, and the preset stir-fry angle is set by a person skilled in the art according to actual conditions. Only when the pressing plate 130 is located above the contact switch 400, the user can trigger the contact switch 400 by pressing the valve stem 120. The positioning device 300, the contact switch 400 and the auxiliary stir-fry assembly 500 are all connected to the controller 200, and the positioning device 300 can send the angle it detects to the controller 200, and the controller 200 determines whether the angle at which the valve stem 120 is located is the preset stir-fry angle, and also determines whether the contact switch 400 is triggered. When the positioning device 300 detects that the valve stem 120 is at the preset stir-fry angle and the contact switch 400 is triggered, the controller 200 controls the auxiliary stir-fry component 500 to start working, and the gas stove enters the stir-fry mode. Since the positioning device 300 can accurately detect the angle of the valve stem 120, there will be no large angle deviation of the micro switch, so the stir-fry position can be accurately located to ensure the stir-fry heat load accuracy; at the same time, compared with the travel switch, the contact switch 400 is more reliable. When the valve stem 120 is at the stir-fry angle and the user presses and triggers the contact switch 400, the stir-fry function is activated, avoiding the situation where the stir-fry function is not activated.

[0024] In some embodiments, the gas stove that can accurately start the stir-frying function also includes a burner 600, the burner 600 includes a burner head and an ejector pipe 610 connected to the burner head, and the ejector pipe 610 is used to eject gas to the burner head. The ejector pipe 610 is connected to the blast channel 620 and the auxiliary air intake pipeline 630, and the auxiliary stir-frying component 500 includes a blower 510 arranged at the inlet end of the blast channel 620 and a solenoid valve 520 arranged in the auxiliary air intake pipeline 630. When the positioning device 300 detects that the valve stem 120 is at a preset stir-frying angle and the contact switch 400 is triggered, the controller 200 controls the blower 510 to start working, and the blower 510 delivers air to the blast channel 620, and the air will enter the ejector pipe 610 to increase the primary air replenishment; at the same time, the controller 200 also controls the solenoid valve 520 to open, and the auxiliary air intake pipeline 630 is connected, which delivers gas to the ejector pipe 610 to increase the gas supply. As a result, the gas and primary air supply to the burner are increased, which increases the heat load of the burner and forms a stir-fry mode.

[0025] Furthermore, a main air inlet 111 and a nozzle are provided on the valve seat 110 . The nozzle is connected to the main air inlet 111 and arranged toward the ejector pipe 610 . The main air inlet 111 is connected to the gas pipeline, which supplies gas to the nozzle, and the nozzle then injects the gas into the ejector pipe 610 .

[0026] Furthermore, one end of the auxiliary air intake pipeline 630 is fixed on the valve seat 110 and communicated with the main air intake port 111. The auxiliary air intake pipeline 630 also supplies fuel gas through the main air intake port 111, which simplifies the pipeline layout and makes the overall structure more compact.

[0027] In some embodiments, Figure 3 As shown, a power switch 140 is also provided on the valve seat 110. When the valve stem 120 rotates to a preset shutdown angle, the pressing piece 130 can contact and press the power switch 140, so that the power switch 140 is in the off position; when the valve stem 120 rotates away from the preset shutdown angle, the pressing piece 130 can be separated from the power switch 140, so that the power switch 140 is in the on position. When the power switch 140 is in the off position, the controller 200 can control the entire gas stove to stop working. Of course, the power switch 140 can also be a switch for controlling a range hood. When the power switch 140 is in the off position, the controller 200 can control the range hood to stop working through the communication module to achieve the linkage between the range hood and the range hood, and the functions of the entire gas stove are more diverse.

[0028] In some embodiments, the positioning device 300 may be a potentiometer connected to the valve stem 120, and the resistance of the potentiometer changes when the valve stem 120 rotates. Alternatively, the positioning device 300 may also be an encoder connected to the valve stem 120, and the encoder may detect the angle of the valve stem 120. Alternatively, the positioning device 300 may also be an infrared sensor, and the infrared sensor may detect the position of the pressing sheet 130. The infrared sensor may be triggered by the pressing sheet 130 only when the valve stem 120 rotates to a preset stir-frying angle.

[0029] The terms and words used in the above description and claims are not limited to the literal meanings, but are only used by the applicant to enable a clear and consistent understanding of the utility model. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the utility model is provided only for illustration, and not for limiting the utility model as defined by the attached claims and their equivalents.
