Description

Technical Field

[0001] This invention relates to the field of gas stove technology, and in particular to an electronically controlled intelligent valve and its intelligent gas stove. Background Technology

[0002] Current gas stoves are all manually controlled by an ignition switch and controlled by a mechanical valve body, which adjusts the gas flow to achieve the desired heat. Therefore, when using a gas stove, it is often necessary to constantly adjust the gas valve according to the needs of cooking.

[0003] A smart gas stove is a type of gas stove that automatically adjusts its flame intensity simply by triggering a specific function. Most current smart gas stoves use a smart gas valve to control the burner, which connects the burner to the gas pipeline. The smart gas valve uses a stepper motor to rotate the valve core, controlling the gas supply and adjusting the flame size. Specifically, it uses touch-sensitive buttons, with the button panel connected to the control board, which in turn connects to the stepper motor in the smart gas valve. Through pre-programmed settings, it achieves functions such as automatic flame intensity adjustment and automatic flameout.

[0004] Currently, the in-situ detection solution for smart gas stoves involves setting a limit block on the valve body, with a switch mounted on the limit block. One end of the switch is connected to the power supply and control board, while the other end is grounded. A protrusion is mounted on the motor output shaft. When the protrusion rotates to its original position, it contacts the limit block, activating the switch and generating a zero-position signal. The control board receives this signal and determines that it has returned to its original position. However, this solution is prone to mechanical wear, which can lead to increased resistance, loss of the zero-position signal, and inability to return to the original position. Summary of the Invention

[0005] The purpose of this invention is to provide an electronically controlled intelligent valve and its intelligent gas stove, so as to alleviate the technical problem in the prior art where the in-situ detection device suffers from mechanical contact wear, which easily leads to increased resistance value, failure of zero position signal, and inability to return to the original position.

[0006] In a first aspect, the present invention provides an electrically controlled intelligent valve, comprising: a gas valve, a gas valve actuator, and an in-situ detection device;

[0007] The gas valve includes a valve body and a valve core that rotates relative to the valve body;

[0008] The gas valve drive is connected to the valve core for driving the valve core to rotate;

[0009] The in-situ detection device comprises a detection element, a collected element and a control element, one of the detection element and the collected element is fixed relative to the valve body, and the other is fixed relative to the output shaft of the gas valve drive or the valve core; the detection element and the collected element are arranged in non-contact mode, and can output zero potential signal at the corresponding position; the gas valve drive and the detection element are electrically connected with the control element.

[0010] Further, the detection element and the collected element rotate relative to each other;

[0011] One of the detection element and the collected element is projected on the rotation track of the other along the direction of the output shaft of the gas valve drive, and the detection element can output zero potential signal at the axial overlap position.

[0012] Further, the detection element is arranged on a control plate, the control plate is sleeved on the output shaft of the gas valve drive, and is fixed relative to the valve body;

[0013] The collected element is sleeved on the output shaft of the gas valve drive through a fixing element, and a gap is left between the collected element and the detection element;

[0014] The projection of the detection element along the output shaft of the gas valve drive is on the rotation track of the collected element.

[0015] Further, the fixing element adopts a rotating wheel;

[0016] The collected element is embedded in the eccentric position of the rotating wheel.

[0017] Further, the detection element adopts a Hall sensor, and correspondingly, the collected element adopts a magnetic element;

[0018] The rotating wheel is made of non-magnetic material.

[0019] Further, the detection element adopts a Hall sensor, and correspondingly, the collected element adopts a magnetic element;

[0020] Alternatively, the detection element adopts a light receiver, and correspondingly, the collected element adopts a light emitter.

[0021] Further, the electrically controlled intelligent valve further comprises an over-rotation protection device;

[0022] The over-rotation protection device comprises a first limiting element arranged on the valve body and a second limiting element arranged on the output shaft of the gas valve drive;

[0023] The gas valve actuator has a zero position at the zero potential signal output by the detection element. When the gas valve actuator rotates to the zero position, the first limiting member can abut against the second limiting member to prevent the second limiting member from crossing the zero position.

[0024] Furthermore, the first limiting member is a boss protruding from the inner wall of the valve body;

[0025] The second limiting member is a protrusion that extends radially outward along the output shaft of the gas valve drive.

[0026] Furthermore, the valve body is provided with three air outlets;

[0027] The valve core is provided with multiple air distribution holes of varying diameters along the circumferential direction relative to the center of each air outlet.

[0028] Beneficial effects:

[0029] The electronically controlled intelligent valve provided by this invention includes a gas valve, a gas valve actuator, and an in-situ detection device. The gas valve includes a valve body and a valve core that rotates relative to the valve body. The gas valve actuator is drively connected to the valve core. Activating the gas valve actuator causes the valve core to rotate relative to the valve body. Furthermore, one of the detection element and the sampled component is fixed relative to the valve body, while the other is fixed relative to the output shaft of the gas valve actuator or the valve core. Therefore, during the rotation of the valve core relative to the valve body, relative rotation occurs between the detection element and the sampled component. Since the detection element and the sampled component are non-contact, and both can output a zero-potential signal at their corresponding positions, this zero-potential signal is sent to the control element. The control element receives this zero-potential signal to determine whether the gas valve actuator is in the zero position. Thus, this electronically controlled intelligent valve achieves non-contact detection through the in-situ detection device. Compared with existing technologies, this detection method avoids problems such as increased resistance, signal distortion, and inability to return to zero position due to mechanical contact wear, and also avoids safety hazards such as sudden flame changes and gas leaks.

[0030] In a second aspect, the present invention provides an intelligent gas stove, comprising: a stove panel, a burner, a control panel, and an electronically controlled intelligent valve as described in any of the foregoing embodiments;

[0031] Both the burner and the control panel are mounted on the cooktop panel, and the control panel is electrically connected to the control element.

[0032] The gas valve's outlet is connected to the burner's flame ring via a gas pipeline.

[0033] Beneficial effects:

[0034] The intelligent gas stove provided by this invention includes the aforementioned electronically controlled intelligent valve. Therefore, the technical advantages and effects that the intelligent gas stove can achieve also include the technical advantages and effects that the electronically controlled intelligent valve can achieve, which will not be repeated here.

[0053] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0054] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0055] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0056] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0057] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0059] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0060] Reference Figures 1 to 3 This embodiment provides an electrically controlled intelligent valve, which includes a gas valve 100, a gas valve drive 200, and an in-situ detection device. The gas valve 100 includes a valve body 110 and a valve core (not shown in the figure) that rotates relative to the valve body 110. The gas valve drive 200 is drivenly connected to the valve core and is used to drive the valve core to rotate. The in-situ detection device includes a detection element 310, a sampled element 320, and a control element 330. One of the detection element 310 and the sampled element 320 is fixed relative to the valve body 110, and the other is fixed relative to the output shaft 210 of the gas valve drive 200 or the valve core. The detection element 310 and the sampled element 320 are non-contact, and both can cause the detection element 310 to output a zero potential signal at corresponding positions. Both the gas valve drive 200 and the detection element 310 are electrically connected to the control element 330.

[0061] The electronically controlled intelligent valve provided in this embodiment activates the gas valve drive 200, which drives the valve core to rotate relative to the valve body 110. Furthermore, one of the detection element 310 and the data acquisition element 320 is fixed relative to the valve body 110, and the other is fixed relative to the output shaft 210 of the gas valve drive 200 or the valve core. Therefore, during the rotation of the valve core relative to the valve body 110, the detection element 310 and the data acquisition element 320 will rotate relative to each other. Since the detection element 310 and the data acquisition element 320 are non-contact, and both can output a zero-potential signal at their corresponding positions, the detection element 310 sends the zero-potential signal to the control element 330. The control element 330 receives the zero-potential signal and thus determines whether the gas valve drive 200 is in the zero position.

[0062] As can be seen, the electronically controlled smart valve in this embodiment can achieve non-contact detection through the in-situ detection device. Compared with the prior art, this detection method can avoid problems such as increased resistance value, electrical signal distortion, and inability to return to zero due to mechanical contact wear, and will not cause safety hazards such as sudden changes in flame or gas leakage.

[0063] In this embodiment, the detection element 310 and the sampled object 320 rotate relative to each other; the projection of one of the detection element 310 and the sampled object 320 along the output shaft 210 direction of the gas valve drive 200 is on the rotation trajectory line of the other, and the two can make the detection element 310 output a zero potential signal at the axial overlap.

[0064] In simple terms, the detection element 310 or the sampled component 320 can rotate synchronously with the output shaft 210 (or valve core) of the gas valve drive component 200. When one of the detection element 310 and the sampled component 320 rotates to overlap or meet the other in the axial direction, the detection element 310 can collect the corresponding signal of the sampled component 320. At this time, the signal output by the detection element 310 is a zero potential signal.

[0065] Specifically, the detection element 310 and the data acquisition element 320 can be configured in various ways. For example, the detection element 310 can be fixed relative to the valve body 110, and the data acquisition element 320 can be fixed relative to the output shaft 210 of the gas valve drive 200; or, the detection element 310 can be fixed relative to the valve body 110, and the data acquisition element 320 can be fixed relative to the valve core; or, the data acquisition element 320 can be fixed relative to the valve body 110, and the detection element 310 can be fixed relative to the output shaft 210 of the gas valve drive 200; or, the data acquisition element 320 can be fixed relative to the valve body 110, and the detection element 310 can be fixed relative to the valve core.

[0066] It should be noted that, among the aforementioned various setting methods, the specific setting position of the detection element 310 or the data acquisition element 320 can be adjusted appropriately for different methods.

[0067] Optionally, the gas valve actuator 200 can be a stepper motor.

[0068] In this embodiment, one of the detection element 310 and the data acquisition element 320 is fixed relative to the valve body 110, and the other is fixedly connected to the output shaft 210 of the gas valve drive 200. This arrangement simplifies the overall structure of the electronically controlled smart valve compared to fixing the detection element 310 or the data acquisition element 320 relative to the valve core, making it easier to install and fix the detection element 310 or the data acquisition element 320.

[0069] In one specific embodiment of this application, reference is made to Figure 1 or Figure 3The detection element 310 is disposed on the control board 400, which is loosely fitted onto the output shaft 210 of the gas valve drive 200 and fixed relative to the valve body 110. The sampled element 320 is fixedly fitted onto the output shaft 210 of the gas valve drive 200 by a fixing member, and a gap is left between the sampled element 320 and the detection element 310. The projection of the detection element 310 along the output shaft 210 of the gas valve drive 200 is on the rotation trajectory line of the sampled element 320.

[0070] It should be noted that the aforementioned "empty sleeve" means that the control board 400 is sleeved on the output shaft 210 of the gas valve drive 200, but there is a gap between the two, so that the control board 400 does not rotate with the output shaft 210 of the gas valve drive 200; in addition, the sampled component 320 is fixedly sleeved on the output shaft 210 of the gas valve drive 200 by a fixing member, and the sampled component 320 can rotate with the output shaft 210 of the gas valve drive 200 under the drive of the fixing member.

[0071] In this specific embodiment, the detection element 310 is fixed relative to the valve body 110, and the sampled component 320 is fixedly sleeved on the output shaft 210 of the gas valve drive component 200, and can rotate synchronously with the output shaft 210 of the gas valve drive component 200. When the sampled component 320 rotates synchronously with the output shaft 210 of the gas valve drive component 200 to the axial overlap point, the detection element 310 outputs a zero potential signal. In addition, a gap is left between the sampled component 320 and the detection element 310, which can realize non-contact detection and avoid mechanical wear between the two.

[0072] Furthermore, in this embodiment, a seal is connected to the upper region of the valve body 110 by fasteners to seal the upper region of the valve body 110. The side of the seal near the control plate 400 is not flat enough, so a fixing plate can be added here. Specifically, the fixing plate is loosely fitted onto the output shaft 210 of the gas valve drive 200 and fixedly connected to the seal. The control plate 400 is fixedly connected to the fixing plate so that the control plate 400 is fixedly installed on a flatter fixing plate, thereby increasing the installation stability of the control plate 400.

[0073] Please continue to refer to Figure 3 The fixing component is a rotating wheel 500; the sampled component 320 is embedded in the eccentric position of the rotating wheel 500. This setting facilitates the installation of the sampled component 320. In specific installation, the sampled component 320 can be embedded in the eccentric position of the rotating wheel 500 first, and then the rotating wheel 500 can be fixedly sleeved on the output shaft 210 of the gas valve drive component 200.

[0074] Optionally, the surface of the rotating wheel 500 can be circular or rectangular; there is no restriction on this. Meanwhile, the sampled component 320 can be embedded in the rotating wheel 500 via snap-fit, plug-in, adhesive, or threaded connection.

[0075] Furthermore, the detection element 310 adopts a Hall sensor, and the corresponding data acquisition element 320 adopts a magnetic element; wherein, the rotating wheel 500 is made of non-magnetic material, and the gas valve drive element 200 is determined to be in the original position (or zero position) state by the magnetic flux signal.

[0076] For example, the rotor 500 may be made of non-metallic materials, such as aluminum or copper. For instance, the rotor 500 may be made of plastic and may be directly injection molded onto the output shaft 210 of the gas valve actuator 200.

[0077] In other embodiments, the detection element 310 may be a light receiver, and correspondingly, the sampled element 320 may be a light emitter.

[0078] For example, the detection element 310 can be an infrared sensor.

[0079] In this embodiment, the electronically controlled intelligent valve also includes an over-rotation protection device, which is a dual protection device to prevent the stepper motor from accidentally over-rotating and to prevent the risk of air leakage, thus providing a higher level of safety protection.

[0080] Reference Figures 4 to 7 The over-rotation protection device includes a first limiting member disposed on the valve body 110 and a second limiting member disposed on the output shaft 210 of the gas valve drive 200; the gas valve drive 200 has a zero position when the detection element 310 outputs a zero potential signal, and the first limiting member can abut against the second limiting member when the gas valve drive 200 rotates to the zero position, so as to limit the second limiting member from crossing the zero position.

[0081] In simple terms, the first limiting member is located on the valve body 110, and the second limiting member is located on the output shaft 210 of the gas valve drive 200. Therefore, the second limiting member can rotate relative to the first limiting member. Specifically, the second limiting member rotates under the drive of the output shaft 210 of the gas valve drive 200. When the second limiting member rotates to the position of the first limiting member, the first limiting member restricts the rotation of the second limiting member, that is, it prevents the second limiting member from crossing the zero position, thereby causing the stepper motor to over-rotate. In this embodiment, refer to... Figure 5 and Figure 7 The first limiting member is a boss 111 protruding from the inner wall of the valve body 110; the second limiting member is a protrusion 211 extending radially outward along the output shaft 210 of the gas valve drive member 200.

[0082] Based on the above embodiments, referring to Figure 1 orFigure 2 The valve body 110 is provided with three air outlets 112; the valve core is provided with multiple air distribution holes (not shown in the figure) with successively changing diameters along the circumference relative to the center of each air outlet 112. By rotating the valve core relative to the valve body 110, the opening size of the air outlet 112 can be adjusted, thereby adjusting the air output.

[0083] Furthermore, the three air outlets are spaced apart along the axial direction of the valve core.

[0084] In general technology, the burner includes an inner ring burner cap and an outer ring burner cap, wherein the inner ring burner cap has two rings of flame outlets to form concentric inner ring flames and concentric outer ring flames respectively.

[0085] This embodiment is equipped with three air outlets 112; it can achieve nine levels of firepower adjustment, specifically:

[0086] The first power setting is: concentric inner ring low heat;

[0087] The two power settings are: concentric inner ring low heat and concentric outer ring low heat;

[0088] The three power levels are: concentric inner ring high power and concentric outer ring high power;

[0089] The four power levels are: concentric inner ring high power, concentric outer ring high power, and concentric outer ring low power.

[0090] The five power levels are: high heat on the inner concentric ring, high heat on the outer concentric ring, and low to medium heat on the outer concentric ring.

[0091] The six power levels are: high heat on the inner concentric ring, high heat on the outer concentric ring, and medium heat on the outer concentric ring.

[0092] The seven power levels are: high heat on the inner concentric ring, high heat on the outer concentric ring, and medium-high heat on the outer concentric ring.

[0093] The eight power levels are: concentric inner ring high power, concentric outer ring high power, and concentric outer ring high power.

[0094] The nine power levels are: high fire on the inner concentric ring, high fire on the outer concentric ring, and maximum fire on the outer concentric ring.

[0095] The above nine power levels can meet the needs of different cooking methods. Since this embodiment has a large number of power levels and the power difference between two adjacent power levels is small, the power change value is small. Therefore, the slope of the power change can be made to rise linearly, that is, the power changes linearly, which is safe to use and easy to operate.

[0096] Reference Figure 8This embodiment also provides an intelligent gas stove, which includes: a cooktop panel 600, a burner 700, a control panel 800, and the aforementioned electrically controlled intelligent valve; wherein, the burner 700 and the control panel 800 are both disposed on the cooktop panel 600, and the control panel 800 is electrically connected to the control element 330; the gas outlet 112 of the gas valve 100 is connected to the flame ring of the burner 700 through a gas pipeline. The intelligent gas stove provided in this embodiment includes the aforementioned electrically controlled intelligent valve; therefore, the technical advantages and effects achieved by this intelligent gas stove also include the technical advantages and effects achieved by the electrically controlled intelligent valve, which will not be elaborated further here.

[0097] Specifically, the three gas outlets are connected to the inner and outer fire rings of the burner 700 through three gas pipelines. The inner fire ring has two rings of flame holes, which can form an inner ring fire (i.e., a concentric inner ring fire), a middle ring fire (i.e., a concentric outer ring fire), and an outer ring fire.

[0098] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
