One skilled in the art, however, will understand that the following description illustrates only a preferred embodiment of the invention and that the invention may be practiced without one or more of these details. In addition, some technical features that are well known in the art are not described in detail in order to avoid obscuring the present invention.

The utility model provides a governing valve for cooking utensils. The regulating valve can be manually operated by a user to regulate the gas flow delivered to the burner of the cooker, so as to regulate the firepower of the cooker, including fire-off, small fire, medium fire, big fire and any firepower between the two, limit big fire (used for quick-frying) and the like. The firepower of the stove can be accurately judged by detecting the gas flow. The stove can be a natural gas stove, an artificial gas stove, a liquefied petroleum gas stove and the like.

A regulator valve 100 according to an embodiment of the present invention is shown in fig. 1-2. The principles of the present invention will be described with reference to the drawings.

The regulator valve 100 includes a valve body 110, and an outer annular combustion gas passage 122 communicating to the valve body 110. Optionally, the regulator valve 100 further includes an inner ring gas gallery 124. The valve body 110 can control the flow rate of gas in the gas passage. In the illustrated embodiment, the regulator valve 100 includes an outer ring gas passage 122 and an inner ring gas passage 124, and the principles of the present invention will be described hereinafter with this configuration as an example. Those skilled in the art will clearly understand how to provide a regulating valve and a cooking range by applying the principles provided by the present invention only in the case of providing the outer ring gas passage 122 according to the following description.

Typically, the valve body 110 includes a valve housing and a valve spool. The valve housing is provided with an inlet port 112 (as shown in fig. 2) and a plurality of outlet ports, which cannot be seen in fig. 1-2 because the outlet ports are blocked. The intake port 112 is used to communicate with an intake pipe 310, as shown in FIG. 3. The two air outlets are respectively communicated with the outer ring gas channel 122 and the inner ring gas channel 124.

The valve core is inside the valve housing, rotatable relative to the valve housing, to regulate the amount of gas passing through the valve body 110. The regulator valve 100 may also include a valve stem 130. The valve stem 130 has first and second oppositely disposed ends. A first end of the valve stem 130 is connected to the valve core, and the valve stem 130 rotates the valve core within the valve housing. The second end of the valve stem 130 extends outside the valve housing as shown in fig. 2. The second end of the valve stem 130 is used to connect to an operating member, and the user operates the operating member to rotate the valve stem 130. Thus, the valve stem 130 is rotatable relative to the valve body 110 as a whole.

When the regulator valve 100 is mounted to a cooktop panel, optionally, the second end of the valve stem 130 can extend above the cooktop panel, connecting with the operating member. Such as an ignition knob (not shown). The ignition knob is arranged above the cooker panel. The user rotates the ignition knob to rotate the valve stem 130. In other embodiments not shown, the operating member may also have other configurations and types, so long as the valve stem 130 can be rotated. The ignition knob is configured to be rotatable between 0-120 degrees for user manipulation. Accordingly, the valve stem 130 may also be rotated in a range of 0-120 degrees. Alternatively, the valve rod 130 may be in an interlocking relationship with the operating member by the first magnetic member attracting to the second magnetic member on the operating member. In this case, the first magnetic member may be installed at the second end of the valve stem 130. The valve rod is operated by utilizing the traditional ignition knob, the improvement on the cooker in the prior art is small, so that the design period of the product can be shortened, and the updating cost of the product is low.

In a preferred embodiment, the valve core may have a valve core gas passage and a gas hole communicating with the valve core gas passage. The valve core gas passage communicates to the gas inlet 112 of the valve body 110. The gas enters the valve core gas channel through the gas inlet 112 and is delivered to the gas hole on the valve core. The gas holes can cooperate with the two gas outlets when the valve core is rotated relative to the valve housing to regulate the flow of gas delivered to the outer ring gas passage 122 and the inner ring gas passage 124. The regulating valve in the form of a plug valve belongs to a mechanical part, can still keep long service life under the condition of daily frequent operation, and is quick and convenient to open and close. In addition, the regulating valve in the form of the plug valve also has the advantages of small fluid resistance, simple valve structure, relatively small volume, light weight, convenience in maintenance, good sealing performance, low noise and the like.

The outer ring gas channel and the inner ring gas channel are communicated to a large fire cover and a small fire cover of a burner of the stove through a large fire venturi and a small fire venturi respectively, the large fire cover is used for generating outer ring flame, and the small fire cover is used for generating inner ring flame. When the existing gas stove is adjusted to be on a big fire, the outer ring gas channel and the inner ring gas channel simultaneously convey gas, and flame is generated on both the outer ring and the inner ring. When the flame is adjusted to a small fire, only the inner ring gas channel conveys gas, and only the inner ring flame is generated. However, the maximum gas quantity that can be delivered by the outer ring gas passage is much larger than that of the inner ring gas passage. Therefore, the outer ring flame has a decisive effect on the firepower of the cooker.

In order to judge the fire power of the cooker, the regulating valve 100 further comprises a flow sensor. As previously mentioned, the outer ring flame has a greater impact on the cooktop fire, so the flow sensor includes an outer ring flow sensor 142, as shown in FIG. 1. The outer ring flow sensor 142 is disposed on the outer ring gas passage 122, and is configured to detect a gas flow in the outer ring gas passage 122. The fire of the cooktop can be evaluated by detecting the gas flow in the outer ring gas passage 122. Specifically, when gas flows through the outer ring gas channel 122, the firepower of the stove can be divided into a 1-gear, a 2-gear and a 3-gear … according to the gas flow, and the larger the gas flow is, the higher the firepower gear is; when no gas flows through the outer ring gas channel 122, only the inner ring flame burns, which belongs to the state of minimum firepower, and the firepower of the cooker at the moment can be set as 0 grade. Optionally, the cooktop fire may not be graded. For example, stove fire is characterized by the magnitude of gas flow; or directly prompt the gas flow to the user.

As described above, the outer-ring gas channel 122 is provided with the outer-ring flow sensor 142, so that the gas flow delivered by the outer-ring gas channel 122 can be detected, the firepower of the cooker can be accurately determined according to the gas flow, and then the user can clearly master the current firepower of the cooker, so that various requirements of the user are met, and the user experience is good.

When the outer loop flow sensor 142 does not detect the gas flow, there may be two cases: 1. the inner ring gas channel 124 is provided with gas to pass through, and the stove is in a small fire state; the inner ring gas channel 124 has no gas passing through, and the stove is in a fire-off state. In order to remind a user that the cooker is in a fire-off state or a small fire state at present, a microswitch can be installed on the valve body 110, and correspondingly, a touch piece is installed on the valve rod 130. Upon rotation of the valve stem 130 by a user operation, a trigger on the valve stem 130 can trigger a microswitch, thereby distinguishing a fire-off condition from a small fire condition.

In a preferred embodiment, the micro-switches are connected in series to the display 320 (shown in FIG. 3) of the cooktop. The display device 320 begins to power on when the microswitch is triggered. When the microswitch is not triggered, the display device 320 is powered off, and no fire gear is displayed, thereby saving power. Alternatively, it is also possible to display only the shut-down on the display device when the microswitch is not triggered. Of course, the specific display mode can be set by those skilled in the art according to actual needs.

Although it was mentioned above that the inner ring flame has less of an impact on the level of cooktop fire, for more demanding users it may be desirable to take into account the impact of the inner ring flame on the cooktop fire. Thus, in a preferred embodiment, the flow sensor further includes an inner ring flow sensor 144, as shown in FIG. 1. The inner ring flow sensor 144 is disposed on the inner ring gas passage 124, and is configured to detect a gas flow rate in the inner ring gas passage 124. In this way, the amount of the heating power of the cooker as a whole is determined by the gas flow rates detected by the outer ring flow rate sensor 142 and the inner ring flow rate sensor 144. For example, the magnitude of the fire prompted to the user may be a fire gear or the sum of the gas flows detected by the outer loop flow sensor 142 and the inner loop flow sensor 144. Alternatively, the influence factors of the outer ring flame and the inner ring flame on the firepower of the cooker can be considered. The person skilled in the art can determine which way to determine the fire power of the cooker and which way to prompt the fire power of the cooker to the user according to the actual needs.

Since the cooktop generates high temperature during use, in order to avoid the high temperature from affecting the flow sensor, it is preferable that the flow sensor, including the outer ring flow sensor 142 and the inner ring flow sensor 144, be disposed at a position close to the valve body 110. For example, the flow sensor may be disposed at or near the outlet of the valve body 110.

In addition, the measured value of the gas flow may be affected by temperature, and for example and without limitation, the flow sensor preferably employs a gas mass flow meter. The gas mass flowmeter can directly measure the mass flow of the fluid, is not influenced by temperature, and does not need temperature and pressure compensation. The outstanding characteristics of the gas mass flowmeter include no movable parts, small pressure loss, wide range ratio, high precision, high reliability, simple installation and convenient operation. The utility model discloses the gaseous mass flow meter who uses can choose for use current or the various gaseous mass flow meter that probably appear in the future.

It should be noted that the type of the flow sensor is only exemplary, and the present invention does not limit the type of the flow sensor as long as the flow sensor can be installed on the gas channel for detecting the gas flow conveyed in the gas channel.

According to another aspect of the present invention, there is also provided a range, as shown in fig. 3. The cooktop includes any of the regulating valves 100 described above. Furthermore, the hob comprises a display device 320 and a control device (not shown). The display device 320 is used for displaying the firepower of the cooker. The control device is connected to the flow sensor of the regulating valve and to the display device 320. In the illustrated embodiment, the flow sensors include an outer ring flow sensor 142 and an inner ring flow sensor 144. In other embodiments not shown, only the outer loop flow sensor 142 may be included.

The control device controls the display device 320 to display the firepower of the cooker based on the gas flow detected by the flow sensor. The control means may be provided on the hob, e.g. integrated onto a control panel of the hob, or integrated onto the display means 320, or provided around the display means 320. For an integrated range having a range hood, the control device may be integrated with a controller of the range hood. The utility model discloses do not prescribe a limit to controlling means's position. Illustratively, the control device may include a control circuit. Illustratively, the control circuit may be built by using electronic components such as comparators, registers, digital logic circuits, etc., or may be implemented by using processor chips such as a single chip, a microprocessor, a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), a Programmable Logic Array (PLA), an Application Specific Integrated Circuit (ASIC), etc., and peripheral circuits thereof.

Through the firepower that shows cooking utensils on display device 320, the user can know the present firepower of cooking utensils directly perceivedly accurately, satisfies user's multiple demand, and user experience is good.

Exemplarily, the display device 320 may be disposed below the cooktop panel 330, correspondingly, the portion of the cooktop panel 330 is made of a light-transmissive material. Illustratively, the control device may be disposed around the display device 320, connected with the display device 320.

Preferably, the display device 320 is a display screen capable of digital display, and is used for displaying the gas flow detected by the flow sensor and/or the fire gear of the cooker. The display screen can be an LED display screen or an LCD display screen.

Alternatively, the display device 320 may also be a device that can display the fire of the cooking range only by brightness, such as a plurality of indicator lights. The amount of fire is displayed by the number of lights that are lit.
