Example 1
Referring to fig. 1-3, the present embodiment provides a valve body structure for reversible start-up of stir-frying, which is applied to a gas stove, and includes a valve body 11 and a valve core 12. The valve body 11 has a valve cavity 111 with one end open, an air inlet 112, an inner ring air outlet 113 and an outer ring air outlet 114, and the valve cavity 111 communicates with the air inlet 112, the inner ring air outlet 113 and the outer ring air outlet 114, respectively. The valve core 12 is rotatably disposed in the valve cavity 111, and the valve core 12 has a central air passage 120, an air inlet portion (not shown in the figure), and an outer ring air outlet portion (not shown in the figure), and the central air passage 120 communicates with the air inlet portion, the inner ring air outlet 113, and the outer ring air outlet portion, respectively.
By rotating the valve core 12, the air inlet 112 can be selectively communicated with the air inlet portion, and the outer ring air outlet 114 can be selectively communicated with the outer ring air outlet portion. When the inner ring air outlet 113 is communicated with the air inlet 112 through the central air passage 120 and the air inlet part in turn, an inner ring air path is formed; an outer ring gas path is formed when outer ring gas outlet 114 communicates with gas inlet 112 sequentially through outer ring gas outlet, central gas passage 120, and gas inlet.
Referring to fig. 6-9, the valve body structure has an off-gear, a large fire gear, and a small fire gear that are sequentially ordered in a forward direction (i.e., counterclockwise direction), and the valve body structure of the present embodiment also has a quick-fry gear for use as a quick-fry start gear that is disposed between the large fire gear and the off-gear, i.e., the quick-fry gear is located in a reverse direction (i.e., clockwise direction) of the large fire gear. When the valve core 12 rotates to a big fire gear, the inner ring air channel and the outer ring air channel both give off air, and refer to fig. 8; when the valve core 12 is reversed from the big fire gear to the quick-frying gear, the gas flow of the inner ring gas outlet 113 and/or the outer ring gas outlet 114 is increased, so that the gas flow of the inner ring gas circuit and/or the outer ring gas circuit can be increased instantaneously. When the quick-frying gear is started and the required set time is reached, the valve core 12 is controlled to rotate forward to restore to a big fire gear, the load is reduced, and quick-frying is finished.
The valve core 12 is provided with a conical section and a connecting section which are oppositely arranged, the central air passage 120 is arranged at the central position of the conical section of the valve core 12 and penetrates through one surface of the conical section, which is away from the connecting section, so that one end of the central air passage 120, which is away from the connecting section, is always communicated with the inner ring air outlet 113.

When the valve core 12 rotates to a fire gear other than the quick-fried gear, the air inlet 112 can be selectively communicated with the radial outer end of the at least one air inlet hole 122; when the valve core 12 rotates to the quick-frying gear, the air inlet 112 cannot be communicated with the central air passage 120 through any air inlet hole 122, as shown in fig. 7.
The air inlet part further comprises a stir-fried air inlet hole 121, the stir-fried air inlet hole 121 is arranged on the outer side wall of the conical section of the valve core 12 and positioned behind the reverse direction of the air inlet hole group, the radial inner end of the stir-fried air inlet hole 121 is always communicated with the central air passage 120, and the radial outer end is selectively communicated with the air inlet 112. Alternatively, the unit ventilation area of the stir-fried air inlet hole 121 is larger than the unit ventilation area of the air inlet hole 122, so that when the valve core 12 is reversed from the big fire gear to the set gear, the air inlet 112 is communicated with the central air passage 120 only through the stir-fried air inlet hole 121, and the flow of the inner ring air passage is instantaneously increased at this time, referring to fig. 7-8.
Referring to fig. 6-9, the outer ring air outlet comprises an outer ring air vent 1240 and an outer ring air outlet groove 1241, wherein the outer ring air vent 1240 is arranged on the outer side wall of the conical section of the valve core 12, the radial inner end of the outer ring air vent 1240 is always communicated with the central air passage 120, and the radial outer end of the outer ring air vent 1240 is selectively communicated with the outer ring air outlet 114. The outer ring air outlet groove 1241 is disposed on the outer side wall of the conical section of the valve core 12 along the circumferential direction and is positioned in front of the reversal direction of the outer ring air vent 1240, the radially outer end of the outer ring air vent 1240 selectively communicates with the outer ring air outlet 114, and the radially inner end communicates with the central air passage 120 through the outer ring air vent 1240. When the valve core 12 rotates to the quick-frying gear, the communication area between the outer ring air outlet 114 and the outer ring air vent 1240 is the largest, referring to fig. 7, at this time, after the fuel gas in the central air flue 120 flows out from the outer ring air vent 1240, the fuel gas directly flows to the outer ring air outlet 114, so that the fuel gas flow of the outer ring air channel is instantaneously increased, quick-frying is started, and instantaneous load lifting or outer ring firepower lifting is realized; when the valve core 12 rotates to the large fire gear, the outer ring air outlet 114 can only communicate with the outer ring air vent 1240 through the outer ring air outlet groove 1241, see fig. 8.

In this embodiment, the unit ventilation area of the outer ring air outlet holes 1242 is smaller than the unit ventilation area of the outer ring air outlet grooves 1241, and when the outer ring air outlet 114 is communicated with any one of the outer ring air outlet 1240, the outer ring air outlet grooves 1241 or the outer ring air outlet holes 1242, the gas flow flowing out of the outer ring air passage can be made different, so that the outer ring firepower with different loads can be formed.

In addition, the valve body structure further comprises a micro switch 14, the valve body 11 is provided with a mounting seat 116 positioned outside the valve cavity 111, a gap 117 positioned between the mounting seat 116 and the valve cavity 111, and the valve cavity 111 is communicated with the outside of the valve body 11 through the gap 117. The micro switch 14 is disposed on the mounting seat 116 of the valve body 11, the micro switch 14 has a spring (not shown) that extends into the valve cavity 111 through the notch 117, and when the driver 13 drives the valve core 12 to rotate, the spring can be triggered or released to output an ignition or flameout signal.

When the gas stove needs to start ignition operation, the controller controls the driver 13 to start, the driver 13 drives the valve core 12 to rotate to an ignition gear so as to enable the air inlet 112 to be communicated with the stir-fried air inlet 121 of the ignition channel, only the inner ring air channel is air-out, other air channels are closed, referring to fig. 4-6, the micro switch 14 sends an ignition signal, and the controller controls the ignition needle to perform ignition according to the signal, so that the valve body structure only provides the most proper needed gas supply amount for ignition, stable ignition under different environmental conditions is met, and the problems of starting ignition under the condition of rated maximum load, easy deflagration and ignition failure and the like are avoided; when the ignition is successful, the driver 13 drives the valve core 12 to rotate to the maximum fire power so as to meet the requirement of high fire combustion.
Example 2
Referring to fig. 1 to 3, this embodiment is different from embodiment 1 in that the valve body 11 further has an intermediate ring air outlet 115, and the valve core 12 further has an intermediate ring air outlet portion (not shown in the drawings), through which the intermediate ring air outlet 115 selectively communicates with the central air passage 120 to form an intermediate ring air passage. The middle ring cavity of the burner 2 communicates with the middle ring air outlet 115 to provide the combustion gas required for the middle ring fire of the burner 2.
When the valve core 12 is reversed from the big fire gear to the quick-frying gear, the gas flow of at least one of the inner ring gas outlet 113, the outer ring gas outlet 114 and the middle ring gas outlet 115 is increased, and in this embodiment, by taking the gas flow increase of the inner ring gas circuit, the middle ring gas circuit and the outer ring gas circuit as an example, referring to fig. 7, quick-frying is automatically started by increasing the gas flow of the inner ring gas circuit, the three-ring fire is improved instantaneously, and the quick-frying schemes such as throttle are solved, and additional components are needed to realize the on-off control of the quick-frying gas circuit, so that the cost is saved. When the quick-frying gear is started and the required set time is reached, the valve core 12 is controlled to rotate forward to restore to a big fire gear, the load is reduced, and quick-frying is finished.
Referring to fig. 6-9, the middle ring air outlet portion includes two middle ring air vents 1250 and middle ring air outlet grooves 1251, the middle ring air outlet grooves 1251 being disposed in the circumferential direction on the outer side wall of the tapered section of the valve core 12, the radially outer ends of which selectively communicate with the middle ring air outlet 115.

Opposite ends of the middle ring outlet channel 1251 are respectively in communication with the central air channel 120 via two middle ring vents 1250. When the valve core 12 rotates to the quick-frying gear, the communication area between the middle ring air outlet 115 and the middle ring air vent 1250 positioned at the rear of the reversing direction is the largest, so that the gas flow of the inner ring gas circuit is increased; when the valve core 12 is rotated to the heavy fire gear, the middle ring air outlet 115 can only communicate with the middle ring air vent 1250 through the middle ring air outlet groove 1251.
The middle ring air outlet portion further comprises at least one middle ring air outlet hole 1252, wherein the middle ring air outlet hole 1252 is arranged on the outer side wall of the conical section of the valve core 12 and in front of the reverse direction of the middle ring air outlet groove 1251, the radial inner end of the middle ring air outlet hole 1252 is communicated with the central air passage 120, and the radial outer end of the middle ring air outlet hole 1252 is selectively communicated with the middle ring air outlet 115. In this embodiment, the unit ventilation of the middle ring air outlet slot 1251 is greater than the unit ventilation of the middle ring air outlet hole 1252, so that when the middle ring air outlet 115 is communicated with the middle ring air outlet slot 1251 or the middle ring air outlet hole 1252, the gas amounts of the middle ring air channels are different, thereby making middle ring firepower with different loads.
The working gear of the valve body structure of the present embodiment is described below with reference to fig. 6 to 9 and 11:

When the quick-frying time length reaches the set time, the rotary motor 13 drives the valve core 12 to rotate forward to restore to 8 gears in the big fire gear, the load is reduced, and the quick-frying is ended.
What has been described above is merely some embodiments of the present utility model. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the utility model.
