Description

Technical Field

[0001] The present invention relates to the technical field of infrared gas stoves, and particularly relates to a cock valve and a stove having the same. Background Art

[0002] With the improvement of living standards, gas appliances including domestic gas stoves, heaters, barbecue grills, etc. have increasingly become essential appliances in people's lives. Infrared gas burners have been accepted by a large number of household consumers due to their excellent performance characteristics such as energy conservation, environmental protection, cleanliness, and safety. Since the combustion mode of infrared burners is complete premixed combustion, with the air volume required for premixing to complete combustion being between 1.03 and 1.10 times, achieving complete combustion, high energy utilization efficiency, and producing less harmful gases (carbon monoxide, nitric oxide), the thermal efficiency of infrared stoves is higher than that of atmospheric burners. Since infrared gas burners use a much larger primary air coefficient than atmospheric burners (0.5 - 0.7), and the furnace cavity for mixing gas and primary air in the burner is relatively large, after evacuating part of the air in the burner furnace cavity and the mixed gas reaches the ignition concentration, the burner can ignite and burn normally. Therefore, when the infrared burner is ignited for the first time in the cold state, there are problems such as low gas concentration, difficult ignition, and low ignition rate. Especially when using piezoelectric ceramic ignition, it is even more difficult to ignite an infrared burner with a high air content, and gas accumulation and deflagration occur, resulting in a poor user experience. This also limits the use and popularization of infrared stoves. Therefore, it is necessary to design a stove that can improve the ignition rate of infrared stoves. Summary of the Invention

[0003] The purpose of the present invention is to provide a cock valve, a cock valve and a stove, by setting the regulation component, so that during ignition, the gas ratio is increased to achieve instant ignition and improve the ignition success rate; during non-ignition, sufficient oxygen can be provided to meet the requirements of the stove for different gas sources.

[0055] As Figures 1 to 5 shown, Figure 1 A schematic diagram of the cock valve provided by the present invention is shown. Figure 2 An exploded view of the cock valve provided by the present invention is shown. Figure 3 A front view of the cock valve provided by the present invention is shown. Figure 4 A sectional view of the cock valve provided by the present invention is shown. Figure 5 A schematic diagram of the cooking appliance provided by the present invention is shown.

[0056] A cock valve according to an embodiment of the present invention, the cock valve comprising:

[0057] A valve body 1, provided with a cavity, an air inlet passage, and an outlet pipe 11, wherein the air inlet passage and the outlet pipe 11 are both communicated with the cavity, and a nozzle 12 is installed on the outlet pipe 11;

[0058] A valve core, arranged in the cavity, for opening or closing the outlet pipe 11;

[0059] A valve cover 2, connected to the valve body 1, for sealing the cavity;

[0060] A valve rod 3, connected to the valve core and passing through the valve cover 2 and extending to the outside of the valve body 1, for driving the valve core to rotate;

[0061] A regulation assembly 4, with one side connected to the valve rod 3 and the other side connected to the outlet pipe 11, so as to change the proportion of oxygen in the nozzle 12 during ignition and not affect the proportion of oxygen in the nozzle 12 during non-ignition.

[0062] Wherein, the valve body 1 is provided with two outlet pipes 11, the two outlet pipes 11 are respectively an outer ring outlet pipe and an inner ring outlet pipe, the valve rod 3 drives the valve core to rotate to open or close the two outlet pipes 11, and since the two outlet pipes 11 are respectively communicated with the outer ring channel and the inner ring channel of the burner 5, by controlling the proportion of the gas output by the two outlet pipes 11 through the regulation assembly 4, the gas proportion in the burner 5 can be regulated;

[0063] The regulation component 4 can be arranged on the inner-ring gas outlet pipe or the outer-ring gas outlet pipe. When the inner-ring channel of the burner 5, especially an infrared burner, requires a larger gas proportion, the regulation component 4 can be installed on the inner-ring gas outlet pipe. By reducing the oxygen proportion ejected by the nozzle 12 on the inner-ring gas outlet pipe, the gas usage requirement of the burner 5 can be met. Similarly, when it is necessary to increase the gas proportion output by the outer-ring gas outlet pipe, the regulation component 4 can be arranged on the outer-ring gas outlet pipe, or the regulation component 4 can be arranged on both gas outlet pipes 11 simultaneously. The gas proportion of one of them can be controlled simultaneously or separately. In this embodiment, when igniting, the regulation component 4 can change the supply amount of the primary air of the nozzle 12, thereby increasing the gas proportion ejected by the nozzle 12 to achieve instant ignition and improve the ignition success rate. When not igniting, it can not affect the supply amount of the primary air of the nozzle 12, enabling the gas to burn fully and improving the combustion performance of the cooking appliance. The present invention can meet the gas source requirements at different stages of the cooking appliance and also meet the requirements of different cooking appliances, with a wide range of applicability.

[0064] In a preferred embodiment of the present invention, the regulation component 4 includes:

[0065] A sleeve 41 sleeved on the gas outlet pipe 11,

[0066] A pushing component 42 fixedly connected to the sleeve 41,

[0067] Wherein, a nozzle air inlet hole 121 is arranged on the outer periphery of the nozzle 12, and the pushing component 42 pushes the sleeve 41 to block the nozzle air inlet hole 121 to change the supply amount of oxygen to the nozzle 12.

[0068] As Figures 1 - 4 shown, a nozzle air inlet hole 121 is arranged on the outer periphery of the nozzle 12, and the pushing component 42 pushes the sleeve 41 to block the nozzle air inlet hole 121 to change the supply amount of oxygen to the nozzle 12. In this embodiment, the oxygen specifically refers to the supply amount of the primary air, and it can also be other oxygen sources as long as the ratio of the gas and oxygen ejected by the nozzle 12 can be regulated.

[0069] In a preferred embodiment of the present invention, the pushing component 42 includes:

[0070] A cam 421 sleeved on the outer periphery of the valve rod 3 and located on the outer periphery of the valve cover 2;

[0071] A pushing plate 422, with one side fixedly connected to the sleeve 41 and the other side cooperating with the cam 421 to push the pushing plate 422 to move linearly,

[0072] Wherein, when igniting, the cam 421 contacts the pushing plate 422; when not igniting, the cam 421 does not contact the pushing plate 422.

[0073] As Figures 1 - 4As shown in the figure, a cam through-hole is provided on the cam 421. The valve stem 3 passes through the through-hole of the cam 421, and the valve stem 3 is in clearance fit with the cam through-hole, so that the cam 421 is clamped in the cam through-hole, and thus the cam 421 can operate along with the valve stem 3. When igniting, the valve stem 3 is pressed, and the valve stem 3 drives the cam 421 to approach the valve cover 2. At this time, the outer circumference of the cam 421 contacts the push plate 422. Then, the cam 421 rotates along with the valve stem 3. At the same time, the rotation of the cam 421 can push the above-mentioned push plate 422 to move left and right. For the convenience of description, in this embodiment, taking the attached drawings of the specification as an example, in the initial state, the distance between the push plate 422 and the cam 421 is the closest. When the cam 421 rotates counterclockwise, the cam 421 pushes the push plate 422 to move left. As the push plate 422 moves left, the nozzle air inlet hole 121 on the nozzle 12 is gradually covered, and the air intake volume of the nozzle 12 also gradually becomes smaller. When the cam 421 rotates 90°, at this time, the protrusion on the cam 421 contacts the push plate 422, and the push plate 422 moves to the farthest end and completely covers the nozzle air inlet hole 121 of the nozzle 12. At this time, the air intake volume of the nozzle air inlet hole 121 is the smallest, and the gas ratio in the gas ejected from the nozzle 12 is the largest, which can rapidly increase the gas ratio in the burner 5 and achieve instant ignition. Figure 3 For example, in the initial state, the distance between the push plate 422 and the cam 421 is the closest. When the cam 421 rotates counterclockwise, the cam 421 pushes the push plate 422 to move left. As the push plate 422 moves left, the nozzle air inlet hole 121 on the nozzle 12 is gradually covered, and the air intake volume of the nozzle 12 also gradually becomes smaller. When the cam 421 rotates 90°, at this time, the protrusion on the cam 421 contacts the push plate 422, and the push plate 422 moves to the farthest end and completely covers the nozzle air inlet hole 121 of the nozzle 12. At this time, the air intake volume of the nozzle air inlet hole 121 is the smallest, and the gas ratio in the gas ejected from the nozzle 12 is the largest, which can rapidly increase the gas ratio in the burner 5 and achieve instant ignition.

[0074] The push plate 422 is Z-shaped and includes:

[0075] The first straight line segment 4221 is fixedly connected to the outer circumference of the sleeve 41;

[0076] The second straight line segment 4222 has one end vertically connected to the first straight line segment 4221;

[0077] The third straight line segment 4223 has one end vertically connected to the other end of the second straight line segment 4222, and the other end is tangent to the outer circumference of the cam 421, so that when igniting, the outer circumference of the cam 421 abuts against the third straight line segment 4223;

[0078] Wherein, the other end of the third straight line segment 4223 is flanged 4224 in the direction away from the cam 421, and the flange 4224 does not contact the cam 421, so that when not igniting, the push plate 422 does not contact the cam 421.

[0079] Such as Figures 1 - 4As shown, the pushing plate 422 is Z-shaped, including a first straight segment 4221, a second straight segment 4222, and a third straight segment 4223. Among them, the first straight segment 4221 is fixedly connected to the outer periphery of the sleeve 41, the second straight segment 4222 connects the first straight segment 4221 and the third straight segment 4223, and a hem 4224 is provided on the third straight segment 4223. In the initial state, the cam 421 is opposite to the hem 4224 left and right and does not contact. When igniting, the cam 421 approaches the valve cover 2 along with the valve stem 3, so that the outer periphery of the cam 421 abuts against the third straight segment 4223. As the cam 421 rotates leftward, it further pushes the third straight segment 4223 to move leftward. When the cam 421 rotates 90°, the third straight segment 4223 moves to the leftmost distal end, so that the sleeve 41 completely blocks the nozzle air intake hole 121, reducing the primary air supply amount of the nozzle air intake hole 121, increasing the proportion of the gas ejected by the nozzle 12, and increasing the ignition success rate. After the ignition is successful, the cam 421 returns to the initial position. At this time, the hem 4224 does not contact the cam 421, and the movement of the cam 421 does not affect the primary air supply amount of the nozzle air intake hole 121. In addition, the hem 4224 can facilitate the embedding of the cam 421 into the third straight segment 4223.

[0080] In a preferred embodiment of the present invention, the pushing assembly 42 further includes:

[0081] A fixing bracket 423, sleeved on the air outlet pipe 11 and located between the cam 421 and the sleeve 41. Among them, the fixing bracket 423 is provided with a threaded hole;

[0082] A screw 424, threadedly connected to the threaded hole. Among them, the pushing plate 422 is sleeved on the outer periphery of the screw 424 to perform a linear motion along the screw 424.

[0083] A fixing block 4225 for connecting the screw 424 is installed on the inner side of the second straight segment 4222. The fixing block 4225 is provided with a first through hole, and the first straight segment 4221 is provided with a second through hole corresponding to the through hole of the fixing block 4225. The screw 424 passes through the first through hole and the second through hole so that the pushing plate 422 is sleeved on the outer periphery of the screw 424;

[0084] Among them, the outer diameters of the first through hole and the second through hole are both larger than the outer diameter of the screw 424, so that the pushing plate 422 performs a linear motion along the screw 424.

[0085] Such as Figures 1 - 4As shown, the fixed bracket 423 is located between the first straight segment 4221 and the third straight segment 4223. The screw 424 is threadedly connected to the fixed bracket 423, and the screw 424 passes through the first through-hole and the second through-hole. Since the outer diameters of both the first through-hole and the second through-hole are larger than the outer diameter of the screw 424, the pushing plate 422 can perform linear motion along the screw 424. In addition, the fixed bracket 423 can also define the movement range of the pushing plate 422 left and right, avoiding unnecessary formation. When the cam 421 is in the initial position, the sleeve 41 completely does not block the nozzle air inlet hole 121. When the cam 421 rotates 90°, it completely blocks the nozzle air inlet hole 121, realizing the regulation of the gas ratio or oxygen ratio of the gas ejected from the nozzle 12 to meet the gas source requirements of different cooktops.

[0086] In a preferred embodiment of the present invention, the regulating assembly 4 further includes:

[0087] A return spring 43, sleeved on the screw 424, with one end abutted against the pushing plate 422 and the other end connected to the fixed bracket 423. Among them, when not igniting, the return spring 43 pushes the pushing plate 422 to reset the sleeve 41.

[0088] As Figures 1 - 4 shown, the return spring 43 is sleeved on the screw 424, with one end abutted against the pushing plate 422 and the other end connected to the fixed bracket 423. As the cam 421 rotates leftward, the return spring 43 is continuously compressed. When the cam 4211 returns to its original position, that is, when not igniting, at this time the cam 421 is not in contact with the pushing plate 422, and the return spring 43 can push the pushing plate 422 to move rightward, so that the sleeve 41 no longer blocks the nozzle air inlet hole 121. At this time, rotating the valve stem 3 and the cam 421 will not affect the primary air supply amount of the nozzle 12. Ensure that after ignition, sufficient gas source can be provided for the nozzle 12 to improve the combustion performance of the cooktop.

[0089] In a preferred embodiment of the present invention, a cam spring 4211 is provided between the cam 421 and the valve cover 2, so that the cam 421 is separated from the pushing plate 422 when not igniting;

[0090] There is a circlip 4212 on the outer side of the cam 421. The position of the cam 421 is limited by the cam spring 4211 and the circlip 4212, so that the cam 421 is in contact with the pushing plate 422.

[0091] As Figures 1 - 4As shown, a cam spring 4211 is disposed between the cam 421 and the valve cover 2. When ignition occurs, the cam 421 approaches the valve cover 2 along with the valve stem 3. At this time, the cam spring 4211 is compressed. After ignition is completed, the cam spring 4211 can push the cam 421 away from the valve cover 2, causing the cam 421 to return to its original position and disengage from the push plate 422, thus avoiding affecting the primary air supply amount to the nozzle 12.

[0092] In a preferred embodiment of the present invention, the axis of the air outlet pipe 11 is perpendicular to the axis of the valve stem 3 so that the outer periphery of the cam 421 contacts the push plate 422.

[0093] As Figures 1 - 4 shown, the cam 421 includes an arc segment and a raised segment. Among them, in the initial state, the arc segment contacts the push plate 422. At this time, the connection line between the highest point of the raised segment and the center of the arc segment is perpendicular to the axis of the air outlet pipe 11. In this way, when the cam 421 rotates 90°, the push plate 422 moves to the farthest distance from the center of the cam 421, that is, the center of the arc segment. This setting can facilitate the calculation of the movement stroke of the push plate 422, and further design the installation position of the sleeve 41 on the air outlet pipe 11. The structure is simple and easy to operate.

[0094] A cooking stove according to an embodiment of the present invention, the cooking stove includes:

[0095] A cock valve as described in any one of the above;

[0096] A burner 5;

[0097] Wherein, the air outlet pipe 11 of the cock valve is communicated with the input end of the burner 5.

[0098] Wherein, the cock valve is used to control the intake amount of gas in the burner 5. The cooking stove in this embodiment includes a cock valve as described in any one of the above. Since the above cock valve has the above technical effects, the cooking stove having the above cock valve should also have the same technical effects.

[0099] During ignition, press the valve stem 3. The cam 421 moves downward accordingly, and the cam spring 4211 is compressed. The outer periphery of the cam 421 contacts the push plate 422. At this time, rotate the valve stem 3 to drive the cam 421 to rotate counterclockwise. When it rotates to 90°, the highest point of the cam 421 moves the push plate 422 left and right to the farthest position. At this time, the push plate 422 completely blocks the nozzle air inlet hole 121 of the nozzle 12. At this time, the primary air intake of the nozzle 12 decreases, and the content of gas in the cavity of the burner 5 increases rapidly. When it overflows above the inner or outer ring of the burner 5, it is ignited by the high-voltage electric spark emitted by the ignition needle in the burner 5. When the ignition is successful, after releasing the hand, the cam 421 moves upward under the action of the elastic force of the cam spring 4211 and separates from the push plate 422. Under the action of the return spring 43, the push plate 422 is pushed to the right. At this time, the nozzle air inlet hole 121 of the nozzle 12 is completely exposed, and the primary air volume of the nozzle 12 is normally aspirated, enabling the gas to burn fully.
