[0053] For the convenience of explanation and understanding, the gas appliances in the following embodiments and drawings take a gas stove as an example.

[0054] In one embodiment, the gas device is a gas stove, including a panel 610 exposed on the countertop, a burner 620 set on the panel 610, and a gas valve 1000 in this embodiment; in another embodiment, the gas device is a gas stove, compared with the aforementioned embodiment, the panel 610 is omitted, and corresponding holes can be directly opened on the kitchen countertop for installing the burner 620 and the gas valve 1000.

[0055] In one embodiment, the operating member 410 has a first surface and a second surface facing each other. The first surface is provided with a plug hole 413 for plugging with the valve stem 300, and the second surface is provided with a sink 414 for accommodating the bearing member 420, and the sink 414 has a notch with an opening facing upward.

The operating member 410 is provided with a transparent cover plate 415 covering the sink 414, and the operator can observe the data displayed by the display unit 500 through the transparent cover plate 415, and the transparent cover plate 415 and the operating member 410 are sealed and matched to prevent liquid or dust from entering the sink 414 to damage the display unit 500. The transparent cover plate 415 and the operating member 410 are connected and rotate synchronously, and the top surface of the operating member 410 is flush.

[0056] In one embodiment, the bearing member 420 has a connecting rod 421 that is plugged into the valve body 100. During installation, the bearing member 420 is placed in the sink 414 through the notch of the sink 414, and the connecting rod 421 passes through the sink 414 and is connected to the valve body 100. The operating member 410 is provided with an escape groove 416 for escaping the connecting rod 421. The connecting rod 421 is a round rod, and the bearing member 420 is a sheet-like structure, and the two are fixedly connected or integrally connected.

[0057] The valve body 100 includes a bracket 140 for keeping the valve stem 300 upright. The bracket 140 is provided with a positioning seat 141 which is plugged into the connecting rod 421. The positioning seat 141 is provided with a positioning groove 142 for the connecting rod 421 to be inserted. The shape of the positioning groove 142 is a circle that matches the connecting rod 421, or a waist-shaped hole as shown in the figure for easy assembly. The inlet end of the positioning groove 142 is chamfered to guide the insertion of the connecting rod 421.

[0058] In one embodiment, the display unit 500 includes a circuit board 510 (the circuit board in FIG. 6 is for illustration only, and the electronic components are omitted) and a light-emitting element disposed on the circuit board 510. The circuit board 510 is connected to the carrier 420, for example, fixed by screws as shown in the figure, to facilitate maintenance and replacement. The light-emitting element is a cathode ray tube or an LED, which is used to display numbers, etc. The gas valve 1000 also includes a shielding member 520 disposed above the circuit board 510. The shielding member 520 has a light guide hole 521 aligned with the light-emitting element, so that the display effect is better and the appearance is simpler, and the shielding member 520 and the transparent cover plate 415 form a secondary protection for the circuit board 510. The shielding member 520 and the circuit board 510 are connected by screws, and the shielding member 520 is fixed to the carrier 420 by screws.

[0059] In one embodiment, the gas valve 1000 further includes an input unit for inputting control parameters to the gas device, for example, the input unit includes a circuit board and a sensing button 531 arranged on the circuit board, wherein the circuit board is the same as or different from the aforementioned circuit board 510, and preferably the two circuit boards are the same. The operator can operate the sensing button 531 to input corresponding control parameters, such as the setting of the stove fire duration, etc. In order to realize the display of parameters and the input of working parameters, the circuit design on the circuit board is a prior art, such as the technical solution disclosed in CN213983677U, which will not be repeated in this application. In combination with the aforementioned shielding member 520, the shielding member 520 is provided with a positioning hole 522 for positioning the sensing button 531.

[0060] In one embodiment, the gas valve 1000 further includes a solenoid valve 160 for controlling the on / off of the air intake passage. As in the prior art, the solenoid valve 160 is normally closed. When igniting, the operating member 410 needs to be pressed, and the valve stem 300 moves downward to drive the solenoid valve 160 to open, thereby achieving ignition. In combination with this embodiment, after the combustion time is set, once the preset time is reached, the solenoid valve 160 is closed, and the corresponding burner is turned off.

[0061] The present application also provides a gas device, including the gas valve 1000 with a display function of any of the above embodiments. It is emphasized again that the gas device is a gas stove or a water heater, and the gas device also includes a central control unit 630 for receiving detection signals, input signals, and output signals. The central control unit 630 can use conventional circuits and chips in the prior art, which will not be described in detail herein.

[0062] For example Fig. 9 As shown, the gas device is a gas stove, which includes at least one of a flameout detection unit, an ignition unit and an anti-burning dry detection unit, all of which are connected to a central control unit 630, and the central control unit can adopt an existing conventional design, such as the solutions disclosed in CN217685158U, CN218411474U, CN218161903U, and CN219263325U. The following is an example of one of the functions of the gas valve in the gas stove of the present application:

[0063] Burning time setting:

[0064] Press the operating part to open the solenoid valve, rotate the operating part, the burner is ignited successfully, and the indicator light at the induction button lights up;

[0065] Press the transparent cover to operate the sensing button, the light-emitting element works, and the burning time is displayed as adjustable, wherein the sensing button includes a first sensing button and a second sensing button, which are respectively used to control the decrease and increase of the burning time;

[0066] After a certain period of time without pressing the button, the burning time starts to count down. During this period, you can press the sensor button again or rotate the operating part to adjust the size of the stove. No matter how the operating part is rotated, the position of the sensor button and the direction of the number remain unchanged, which is convenient for the operator to observe and use.

[0067] When the burning time is reached, the solenoid valve closes and the stove fire is turned off.

[0068] The gas valve with display function of the present application has a display unit installed on a carrier, which is used to display the working status of the gas equipment, such as flame size, burning time, flameout, dry burning, temperature and other information. The display unit is integrated on the knob assembly, so that the appearance of the gas equipment is simpler, and there is no need to set up an additional display screen for display as in the prior art; and the display unit is kept circumferentially fixed by the carrier and the valve body, so that when the user performs normal ignition, fire adjustment and other operations (i.e., driving the operating member to rotate), the direction of the display unit is always fixed, which is convenient for the operator to identify and implement other operations.

[0069] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0070] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
