Description

Technical Field

[0001] The invention relates to the technical field of gas cookers, and in particular to a gas cooker and an integrated cooker capable of synchronously adjusting the sizes of inner and outer ring flames. Background Art

[0002] The gas valve is a manually operated valve that controls the gas supply in a gas cooker. The valve body of a traditional gas valve has an air inlet channel, an inner ring nozzle air outlet channel and an outer ring nozzle air outlet channel. A rotatable valve core is provided in the valve body, a spring chamber is provided on the upper part of the valve core, and a ventilation chamber is provided on the lower part of the valve core. A valve stem that can drive the valve core to rotate is passed through the valve body. A spring that keeps the valve stem moving upward and detaching from the connection with the valve core is held at the lower end of the valve stem. The spring is installed in the spring chamber of the valve core. The side walls of the valve core are respectively provided with an outer ring fire outlet channel for connecting to the outer ring nozzle air outlet channel and an inner ring fire outlet channel for connecting to the inner ring nozzle air outlet channel.

[0003] When the above-mentioned gas valve is in use, the valve stem is rotated to rotate the valve core in the valve body, and the fire intensity of the outer ring fire is adjusted by using a series of fire adjustment holes of different apertures to communicate with the outer ring gas outlet channel, and when the outer ring fire is adjusted to zero, the inner ring fire still keeps emitting fire. That is, in the process of adjusting the size of the inner and outer ring flames, the traditional gas valve cannot adjust the inner and outer ring flames synchronously. When the outer ring fire is adjusted to a small size, the inner ring fire is still at the maximum state. In normal use, if you want to adjust it to a small fire, the normal operation is to directly close the outer ring flame.

[0004] For this type of gas stove, the inner and outer ring flames cannot be adjusted synchronously (when the outer ring is adjusted to a low flame, the inner ring cannot be adjusted to a low flame), resulting in the flame being unable to burn the bottom of the pot evenly. During the frying process, the pancakes are not cooked through around the edges and become burnt in the middle, thus affecting the quality of the food. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the present invention provides a gas cooker with synchronous adjustment of the size of inner and outer ring flames to solve the above-mentioned traditional problems. By adjusting the ventilation structure of the valve body, the inner and outer ring flames can be adjusted synchronously so that the bottom of the pot is heated evenly.

[0006] The invention also provides a gas cooker which adopts the gas cooker which can synchronously adjust the size of inner and outer ring flames.

[0007] One of the purposes of the present invention is achieved by the following technical solution:

[0008] A gas cooker for synchronously adjusting the size of inner and outer ring flames, comprising a valve body with a valve cavity and a valve core rotatably arranged in the valve body; the valve body is provided with an air inlet hole, an outer ring air outlet hole and an inner ring air outlet hole which are connected to the valve cavity, and the side wall of the valve core is provided with an arc groove; when the valve core is rotated to a first position, a passage area is formed between the arc groove and the air inlet hole, and the arc groove is connected to the outer ring air outlet hole and the inner ring air outlet hole, and when the passage area gradually becomes smaller, the amount of gas entering the outer ring air outlet hole and the inner ring air outlet hole respectively also becomes smaller synchronously; when the valve core is rotated to a second position, the arc groove and the air inlet hole are blocked, and the air inlet hole and the outer ring air outlet hole and the inner ring air outlet hole are blocked.

[0009] Preferably, the arc-shaped groove includes a first connecting groove, a second connecting groove and a third connecting groove which are interconnected, the first connecting groove and the second connecting groove and the third connecting groove form a Z-shaped structure, the first connecting groove is used to connect to the outer ring air outlet, and the third connecting groove is used to connect to the inner ring air outlet.

[0010] Preferably, the air inlet, outer ring air outlet and inner ring air outlet are staggered, the outer ring air outlet is located at the upper end of the inner ring air outlet, and the air inlet is located at the lower end of the inner ring air outlet.

[0011] Preferably, the air inlet and the outer ring air outlet are arranged opposite to each other, and the inner ring air outlet is arranged on the side of the air inlet.

[0016] Preferably, the gas cooker further comprises a burner, and the burner is respectively connected to the outer ring air outlet and the inner ring air outlet of the gas cooker through gas distribution pipes.

[0017] The second object of the present invention is achieved by adopting the following technical solution:

[0018] An integrated stove comprises the above-mentioned gas stove for synchronously adjusting the size of inner and outer ring flames and a burner, wherein the burner is connected to the outer ring air outlet and the inner ring air outlet of the gas stove respectively through a gas distribution pipe.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The gas cooker of the present invention changes the air intake mode of the traditional gas cooker.

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0028] In the description of the present invention, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0029] In the description of the present invention, it should be understood that when an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be intermediate elements at the same time. On the contrary, when an element is said to be "directly" connected to another element, there are no intermediate elements.

[0030] See also Figure 1-3 , is a gas cooker 100 of a preferred embodiment of the present invention, which is used to achieve synchronous adjustment of the size of the inner and outer ring flames. Specifically, the gas cooker 100 includes a valve body 10 with a valve cavity 11 and a valve core 20 rotatably arranged in the valve body 10; the valve body 10 is provided with an air inlet 12, an outer ring air outlet 13 and an inner ring air outlet 14 connected to the valve cavity 11, and the side wall of the valve core 20 is provided with an arc groove 21; when the valve core 20 is rotated to the first position, a passage area is formed between the arc groove 21 and the air inlet 12, and the arc groove 21 and the outer ring air outlet The hole 13 and the inner ring air outlet hole 14 are connected. When the passage area gradually becomes smaller, the amount of gas entering the outer ring air outlet hole 13 and the inner ring air outlet hole 14 respectively also decreases synchronously (there is no situation where there is no gas in a single outer ring air outlet hole 13 or inner ring air outlet hole 14); when the valve core 20 is rotated to the second position, the arc groove 21 and the air inlet hole 12 are blocked, and the air inlet hole 12 and the outer ring air outlet hole 13 and the inner ring air outlet hole 14 are blocked.

[0031] The above-mentioned gas cooker 100 changes the air intake method of the traditional gas cooker 100. An arc groove 21 is opened on the side wall of the valve core 20, and the gas is distributed through the arc groove 21. When the valve core 20 is rotated, the passage area formed between the air inlet hole 12 and the arc groove 21 has different sizes of connected areas, so as to adjust the gas intake amount, so that the amount of gas entering the outer ring air outlet 13 and the inner ring air outlet 14 will increase or decrease synchronously, and finally the outer ring fire and the inner ring fire will change synchronously, so that the bottom of the pot is heated evenly, thereby ensuring the quality of the food.

[0032] The first position and the second position mentioned above can be understood from the following aspects: the first position is mainly the state where the air inlet 12, the outer ring air outlet 13, and the inner ring air outlet 14 are all connected to the arc groove 21, and the other states may be in the second position or the third position (i.e., the connected or disconnected relationship between the air inlet 12, the outer ring air outlet 13, and the inner ring air outlet 14 that do not appear in the second position or the first position). When the valve core 20 rotates to the third position, the possible connection relationship is: the air inlet 12 is connected to the arc groove 21, but the outer ring air outlet 13 and the inner ring air outlet 14 are not connected to the arc groove 21; the air inlet 12 is not connected to the arc groove 21, but the outer ring air outlet 13 may be connected to the arc groove 21, or the inner ring air outlet 14 may be connected to the arc groove 21, or the outer ring air outlet 13 and the inner ring air outlet 14 are connected to the arc groove 21 at the same time.

[0033] In one embodiment, the arc groove 21 includes a first connecting groove 210, a second connecting groove 211 and a third connecting groove 212 which are interconnected. The first connecting groove 210, the second connecting groove 211 and the third connecting groove 212 form a Z-shaped structure. The first connecting groove 210 is used to connect the outer ring air outlet 13, and the third connecting groove 212 is used to connect the inner ring air outlet 14. The gas cooker 100 can evenly distribute the gas flow through the arc groove 21 of the Z-shaped structure of the valve core 20. It can be understood that the structure formed by the first connecting groove 210, the second connecting groove 211 and the third connecting groove 212 can also be an S-shaped, wavy or other structure that can achieve this function. Among them, the aperture of the outer ring air outlet 13 is larger than the aperture of the inner ring air outlet 14, and the aperture of the air inlet 12 is located between the apertures of the outer ring air outlet 13 and the inner ring air outlet 14. Preferably, the air inlet 12 , the outer ring air outlet 13 , and the inner ring air outlet 14 are staggered, the outer ring air outlet 13 is located at the upper end of the inner ring air outlet 14 , and the air inlet 12 is located at the lower end of the inner ring air outlet 14 .

[0034] In another embodiment, the air inlet 12 and the outer ring air outlet 13 are arranged opposite to each other, and the inner ring air outlet 14 is arranged on the side of the air inlet 12. It can be understood that when the valve core 20 is in the first position, the inner ring air outlet 14 and the air inlet 12 are both located in the third connecting groove 212, which is conducive to synchronously adjusting the size of the inner and outer ring flames through the arc groove 21 of the Z-shaped structure. Further, the arc groove 21 includes a first side groove surface 213 and a second side groove surface 214. When the air inlet 12 is connected with the outer ring air outlet 13 and the inner ring air outlet 14 at the same time, the shortest distance between the outer ring air outlet 13 and the first side groove surface 213 is less than or equal to the shortest distance between the inner ring air outlet 14 and the second side groove surface 214. Preferably, the shortest distance between the outer ring air outlet 13 and the first side groove surface 213 is equal to the shortest distance between the inner ring air outlet 14 and the second side groove surface 214.

[0035] In one embodiment, the valve core 20 is configured to be a structure that decreases from the outside to the inside, and the valve cavity 11 is configured to match the structure of the valve core 20 , so that the valve core 20 and the valve cavity 11 of the valve body 10 can be better sealed.

[0036] In one embodiment, the air inlet 12 is arranged on the side of the valve cavity 11, which changes the traditional way of air intake from the bottom of the valve body 10 or from the side of the valve core 20, which is conducive to improving the stability of gas supply and effectively ensuring the stability of the flame. Specifically, the valve body 10 includes a first air inlet channel 15, a second air inlet channel 16 and a third air inlet channel 17 connected in series, the first air inlet channel 15 is used to communicate with an external gas pipe, the second air inlet channel 16 is installed with a solenoid valve (not shown) for controlling the on and off, and the third air inlet channel 17 is connected to the air inlet 12.

[0037] In one embodiment, the gas cooker 100 further includes a bottom cover (not shown), which is disposed at the bottom of the valve body 10. The bottom cover is a detachable structure, which is conducive to cleaning the valve cavity 11 and other cavities and is convenient for maintenance.

[0038] The operating steps of the above-mentioned gas cooker 100 are:

[0039] S1: The valve core 20 is rotated and the solenoid valve is energized, so that the gas enters the air inlet 12 from the first air inlet passage 15, the second air inlet passage 16 and the third air inlet passage 17 in sequence;

[0040] S2: When the valve core 20 is rotated to the first position, a passage area is formed between the arc groove 21 and the air inlet 12, and the arc groove 21 is connected with the outer ring air outlet 13 and the inner ring air outlet 14; within the first position range, the valve core 20 is rotated to make the passage area reach maximum connection, so that the air output of the outer ring air outlet 13 and the inner ring air outlet 14 is the maximum output, thereby achieving the maximum flame height; the valve core 20 is rotated to make the passage area gradually smaller, so that the air output of the outer ring air outlet 13 and the inner ring air outlet 14 is synchronously reduced, thereby achieving the synchronous reduction of the flame height;

[0041] S3: When the valve core 20 is rotated to the second position, the arc groove 21 and the air inlet hole 12 are blocked, and the air inlet hole 12 and the outer ring air outlet hole 13 and the inner ring air outlet hole 14 are blocked, that is, the outer ring air outlet hole 13 and the inner ring air outlet hole 14 are not ventilated at the same time.

[0042] In addition, the present invention also provides a gas cooker, which also includes a burner 200, and the burner 200 is connected to the outer ring air outlet 13 and the inner ring air outlet 14 of the gas cooker 100 through a gas distribution pipe 210. By installing the gas cooker 100, the size of the inner and outer ring flames can be adjusted synchronously. In another embodiment, the gas cooker 100 is also provided with a positioning component and an indicating component, making it easier to operate and simple to understand.

[0043] The working principle of the above-mentioned gas cooker is:

[0044] Original state: the arc groove 21 of the valve core 20 is disconnected from the air inlet 12, the outer ring air outlet 13 and the inner ring air outlet 14, so that the gas cannot enter the outer ring air outlet 13 and the inner ring air outlet 14 through the arc groove 21, and the burner 200 cannot be ignited.

[0045] Ignition state: the valve core 20 is rotated and the solenoid valve is energized, so that the arc groove 21 is connected with the air inlet hole 12, the outer ring air outlet hole 13 and the inner ring air outlet hole 14 at the same time, and the burner 200 is ignited.

[0046] Synchronous fire regulation process: when the passage area formed by the arc groove 21 and the air inlet hole 12 is connected to the maximum area, the gas enters the outer ring air outlet 13 and the inner ring air outlet 14 along the arc groove 21, so that the flame reaches the maximum height; by rotating the valve core 20, the passage area is gradually reduced, and the gas entering the arc groove 21 is also gradually reduced, so that the amount of gas entering the outer ring air outlet 13 and the inner ring air outlet 14 is also synchronously reduced, thereby achieving the synchronous reduction of the flame height.

[0047] In addition, the present invention further provides an integrated stove, which includes the gas stove 100 for synchronously adjusting the size of inner and outer ring flames as described above.

[0048] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0049] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. 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 invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
