Detailed Description

The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.

The invention provides a kitchen range which comprises a gas valve and a gas knob. Wherein, as shown in fig. 1, the gas valve includes valve body 1 and valve rod 2, and valve rod 2 can be relative when lieing in the rotation height B the valve body 1 is rotatory, and the top at valve rod 2 is installed to gas knob (not shown in the figure), and the user makes valve rod 2 remove to rotation height B from initial position A through pressing down the gas knob, makes the gas in the gas valve switch on to the combustor of cooking utensils in, afterwards, the rotatory gas knob of rethread to the gas volume of the furnace end (not shown in the figure) output of change gas valve to cooking utensils.

As shown in fig. 2 to 4, the valve stem 2 of the gas valve has a positioning end 21 for positioning on the inner wall surface of the valve body 1, the positioning end 21 is embodied as a protruding structure formed on the outer surface of the valve stem 2 and protruding horizontally outward (see fig. 5), and the valve body 1 is correspondingly provided with a rotation limiting channel 11 (see fig. 4) on the inner wall at the rotation height B, and the rotation limiting channel 11 is used for accommodating and limiting the positioning end 21 when the valve stem 2 rotates, so that the positioning end 21 can rotate in a specific direction.

As shown in fig. 3 and 4, a rising limit passage 13 and a falling limit passage 12 are correspondingly arranged on the inner side of the valve body 1. Wherein, the two ends of the descending limit channel 12 are respectively communicated with the initial position a and the rotation limit channel 11, the descending limit channel 12 accommodates the positioning end 21 when the valve rod 2 moves downwards, and limits the degree of freedom of movement of the positioning end 21 towards other directions except the descending direction. The ascending limit channel 13 is located beside the descending limit channel 12, two ends of the ascending limit channel 13 are respectively communicated with the initial position a and the rotation limit channel 11, and the descending limit channel 12 receives and limits the positioning end 21 when the valve rod 2 moves upwards. Through set up spacing passageway 13 of rising and the spacing passageway 12 of decline simultaneously in valve body 1, when making location end 21 remove between initial position A and rotation height B, its route of rising is different with the route of decline, realizes improving the purpose that the user used and feels and experienced.

Specifically, when the user rotates the gas knob and extinguishes, the user can only rotate the gas knob without pressing down the gas knob, and therefore, the positioning end 21 of the valve rod 2 connected with the rotating gas can return to the initial position a along the arc direction extending obliquely upward through the ascending limit passage 13. Meanwhile, to ensure that the positioning end 21 smoothly enters the ascending limit channel 13, the inlet of the ascending limit channel 13 communicating with the rotation limit channel 11 may be closer to one side of the gas knob (see fig. 7) rotated by the user than the descending limit channel 12 to enter the ascending limit channel 13 before the positioning end 21 passes through the descending limit channel 12.

In particular, as can be seen from fig. 6 and 7, the descending limit channel 12 extends vertically downward, and the ascending limit channel 13 extends obliquely upward along the rotation direction of the valve stem 2, so that the ascending and descending of the valve stem 2 can move along two different paths to provide a different use experience for the user. Especially, in the process that the valve rod 2 needs to be screwed back to the initial position A at the rotation height B, when a user looses his hands gradually, the positioning end 21 of the valve rod 2 moves obliquely upwards to the initial position A along the ascending limit channel 13, and the staged operations of pressing the valve rod and rotating the valve rod are not needed, as in ignition, and obvious resilience feeling is not needed to be generated for the hand of the user when the gas knob is screwed back, so that the operation of the stove during flameout is smoother, and the use experience of the user can be obviously improved.

In addition, a guide structure 15 is correspondingly arranged on the channel surface of the rotation limiting channel 11 facing the ascending limiting channel 13, and the guide structure 15 provides an arc surface for guiding the moving direction of the positioning end 21, so that the positioning end 21 can be smoothly moved into the ascending limiting channel 13 through the guide of the guide structure 15 under the condition that a user does not press the gas knob and simultaneously rotates back the gas knob.

Since the ascending limit channel 13 extends from the initial position a to the rotation limit channel 11 obliquely downward along the rotation direction of the valve rod 2, in the process that the user rotates the gas knob to the initial position a, the positioning end 21 of the valve rod 2 moves obliquely upward to the initial position a along the ascending limit channel 13 in the process that the user gradually looses his hand, so that in the process that the gas knob is rotated back to the initial position a, there will be no definite staged operations such as pressing down the gas knob and rotating the gas knob as in the ignition.

Preferably, as shown in fig. 4, the inner wall surface of the valve body 1 further has a one-way limiting structure 14, the one-way limiting structure 14 is located at a communication position between the ascending limiting channel 13 and the descending limiting channel 12, and the one-way limiting structure 14 is used for blocking the positioning end 21 from moving from the descending limiting channel 12 to the ascending limiting channel 13 at the initial position a, so that the positioning end 21 is effectively prevented from moving downwards from the ascending limiting channel 13 to the rotation limiting channel 11 due to misoperation of a user when the positioning end 21 is at the initial position a.

Specifically, the one-way position-limiting structure 14 includes a compressible elastic member 141 and a stopper 142, the stopper 142 is connected to the inner wall surface of the valve body 1 through the elastic member 141, and the stopper 142 has an inclined surface toward the upward movement-limiting passage 13 side, so that the positioning end 21 compresses the elastic member 141 through the stopper 142 from the upward movement-limiting passage 13 side, and the passage into the downward movement-limiting passage 12 is opened; the stopper 142 is a plane perpendicular to the moving path of the positioning end 21 on the side of the downward limiting passage 12, so as to block the positioning end 21 when the positioning end 21 is going to enter the upward limiting passage 13 through the one-way limiting structure 14. In this embodiment, the stopper 142 and the elastic member 141 are compressed downward in the vertical direction when the positioning end 21 moves from the ascending limit path 13 into the descending limit path 12.

As shown in fig. 2, the passage height of the rotation limiting passage 11 is not constant, but varies correspondingly with the variation of the rotation angle of the valve stem 2.

This gas valve can rotate the knob so that valve rod 2 takes place rotatoryly at the user, and when adjusting the firepower size, carry on spacingly and the guide to the location end 21 of valve rod 2 through the rotatory spacing passageway 11 that sets up on valve body 1, the rotation angle that makes valve rod 2 and knob changes and corresponds the change according to valve rod 2, so that the firepower size of gas can also give the user through the altitude variation direct feedback of valve rod 2, further improve the cognition of user to the firepower size change, when effectively improving the rotatory valve rod 2 of user in order to adjust the firepower, the degree of directly perceived to the firepower size of cooking utensils.

Specifically, as shown in fig. 8, the inner wall surface of the valve body 1 has an upper limit surface 16 and a lower limit surface 17, and the upper limit surface 16 and the lower limit surface 17 are disposed to face each other and together form the rotation limit passage 11. When the valve rod 2 rotates relative to the valve body 1, the upper limiting surface 16 can limit the displacement of the positioning end 21 in the upward direction, and the lower limiting surface 17 can limit the displacement of the positioning end 21 in the downward direction, so that when the fire power is adjusted by pressing and rotating the gas knob or lifting and rotating the gas knob by a user, the rotation limiting channel 11 can enable the user to intuitively feel the change of the fire power through the height change of the gas knob when the user rotates the gas knob through the change of the height of the gas knob through the change of the channel.

When driving valve rod 2 to rotate through rotatory gas knob, the gas volume that the gas valve exported also can change thereupon, and in this embodiment, the passageway height of rotatory spacing passageway 11 corresponds the change along with the change of the output gas volume of gas valve. For example, after the gas knob is rotated from the zero point, the output gas quantity of the gas valve starts to increase, when the gas knob is rotated to the 90-degree position, the output gas quantity reaches the maximum, and in the process of continuously rotating the gas knob to 180 degrees, the output gas quantity is correspondingly reduced. Therefore, the height of the rotation limiting channel 11 is increased along with the increase of the gas flow and then correspondingly reduced along with the reduction of the gas flow along with the change of the gas flow, so that the rotation limiting channel is correspondingly matched with the intuitive feeling of the firepower of the cooking range adjusted by the rotation of the gas knob by the user, and the intuitive degree of the user for the firepower of the cooking range is further improved.

Specifically, as shown in fig. 8 and 9, the rotation limiting channel 11 is composed of a plurality of horizontal channel sections 112 with different heights and a circular arc transition section located between the horizontal channel sections 112, during the rotation process of the valve rod 2, the positioning end 21 moves from one horizontal channel section 112 to another horizontal channel section 112 with different heights to realize the height change of the valve rod 2, and the height change is step-wise rather than continuous, so that the height change of the valve rod 2 is more obvious to the feedback of the hand of the user, so that the user can intuitively feel the change of the fire of the cooker.

After the gas knob is rotated from the zero point, the height of the first horizontal channel section 112 is the lowest, and the height of the subsequent horizontal channel section 112 is gradually increased until the gas knob is rotated to the 90-degree position, the height of the subsequent horizontal channel section 112 is decreased, but when the gas knob is rotated to the 180-degree position, the height of the corresponding horizontal channel section 112 is still higher than the height of the corresponding horizontal channel section 112 when the gas knob is positioned at the zero point.

In this embodiment, when ignition is required, as shown in fig. 6, the positioning end 21 moves downward from the initial position a through the descending limit channel 12 and moves into the rotation limit channel 11 at the rotation height B, that is, the valve rod 2 is pressed down to perform ignition operation, and then rotates to perform operation of changing the fire power of the cooker.

When the fire is to be turned off, as shown in fig. 7, the user rotates the valve rod 2 and looses his hand gradually, the positioning end 21 moves into the ascending limiting channel 13 from the rotating limiting channel 11 and gradually ascends to the initial position a along the arc direction, and in the whole process, the knob does not have periodic feedback on the hand of the user, so that the operation hand feeling is smooth, and the user experience degree is good.
