Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
Example 1
As shown in fig. 1 to 3, the present invention provides a gas cooker, which comprises a gas nozzle 1, an injection pipe 2, a cooker fire cover 3, a cooker panel 5, a cooker chassis 6 and a control mechanism, which are sequentially arranged along a gas flowing direction. Wherein, cooking utensils chassis 6 sets up in the below of cooking utensils panel 5 to enclose into a accommodation space 7 that is used for holding other components and parts with cooking utensils panel 5 jointly, gas nozzle 1 with draw penetrate the pipe 2 and set up in accommodation space 7, and cooking utensils fire lid 3 sets up on cooking utensils panel 5.
In addition, the gas cooker has an upper inlet 51 and a lower inlet 61 for supplying air to the injection pipe 2 to be injected and mixed with the gas injected from the nozzle.
In this embodiment, the upper air inlet 51 is disposed on the panel 5 of the cooker, and is located near the joint where the fire cover 3 of the cooker and the panel 5 of the cooker are combined, and is communicated downwards to the accommodating space 7, so that air above the panel 5 of the cooker can enter the accommodating space 7 through the upper air inlet 51, and the purpose of upper air inlet is achieved. The lower air inlet 61 is arranged on the cooker chassis 6 and is communicated upwards to the accommodating space 7, so that air below the cooker panel 5, specifically air inside the cabinet can enter the accommodating space 7 through the lower air inlet 61, and the purpose of lower air inlet is achieved.
Therefore, the gas cooker provided by the invention has the advantages that the upper air inlet 51 and the lower air inlet 61 are arranged at the same time, so that the injection pipe 2 can receive air from the upper air inlet 51 and the lower air inlet 61 at the same time. On this basis, the control mechanism is connected to the upper air inlet 51 and the lower air inlet 61, and adjusts the air inlet state of the injection pipe 2 (see fig. 2 and 3) according to the firepower state of the gas cooker, so as to establish the relationship between the firepower of the gas cooker and the air inlet state of the injection pipe 2, so that the air inlet state of the injection pipe 2 is changed under the corresponding firepower state, the air inlet state can better provide air required for injection to the injection pipe 2, and the gas cooker can be effectively combusted under various firepower conditions.
Particularly, when the cabinet door is opened or closed, air pressure in the cabinet door is easy to fluctuate, so that air pressure in the kitchen range chassis 6 is affected through the lower air inlet 61, air supply is affected, and the condition of flameout of small fire is easily caused.
When the gas cooker is in a big fire state, the fire holes in the inner ring fire cover and the outer ring fire cover are all ignited, oxygen in the air above the cooker panel 5 is quickly consumed, if the upper air inlet state is kept, the quality of a gas mixture is affected easily because the oxygen content in the air injected in the injection pipe 2 is not high, and the problem does not exist in the lower air inlet state. Therefore, when the gas cooker is in a big fire state, the control mechanism should close the upper air inlet 51, so that the injection pipe 2 can only obtain air from the lower air inlet 61, and the problem of insufficient oxygen content in the air during big fire combustion is solved.
In addition, when the firepower state of the gas cooker is between the small fire state and the large fire state, the control mechanism can control the upper air inlet 51 and the lower air inlet 61 to simultaneously supply air to the injection pipe 2, so that the influence on the combustion of the gas cooker can be avoided due to the independent occurrence of the problems of opening and closing a cabinet door or the low oxygen content of the air above and the like.
Of course, what needs to be explicitly stated is: in the embodiment, when the injection pipe 2 is positioned below the panel 5 of the gas cooker, the gas cooker adopts a scheme that the control mechanism adjusts the air inlet state of the injection pipe 2. However, this is only an embodiment for clearly explaining the scheme and principle of the present invention, and in other embodiments, the ejector pipe 2 may be installed above the stove panel 5 or at any other position, and the same purpose as the present embodiment can be achieved by changing the installation positions of the corresponding upper air inlet 51 and the corresponding lower air inlet 61 on the gas stove.
In this embodiment, the control mechanism specifically includes a first cover plate 41, a second cover plate 42 and a driver 43, wherein the first cover plate 41 is disposed corresponding to the upper air inlet 51, the second cover plate 42 is disposed corresponding to the lower air inlet 61, the driver 43 is respectively connected to the first cover plate 41 and the second cover plate 42, the driver 43 can drive the first cover plate 41 to cover the upper air inlet 51, and simultaneously, the second cover plate 42 can also be driven to cover the lower air inlet 61, and the displacement of the first cover plate 41 and the displacement of the second cover plate 42 are respectively controlled by the driver 43.
When the air intake of the ejector tube 2 from the upper air inlet 51 is to be avoided, the driver 43 drives the first cover plate 41 to cover the upper air inlet 51, and when the air intake of the ejector tube 2 from the lower air inlet 61 is to be avoided, the driver 43 drives the second cover plate 42 to cover the lower air inlet 61. Therefore, the "covering state" of the first cover plate 41 and the second cover plate 42 is controlled by the driver 43 to adjust the air intake state of the ejector pipe 2.
In the embodiment, as shown in fig. 4, the first cover plate 41 and the second cover plate 42 are connected to the connecting rod 44 at the same time, and the driver 43 drives the connecting rod 44 to move, so as to drive the first cover plate 41 and the second cover plate 42 to synchronously reciprocate, so that the second cover plate 42 does not shield the lower air inlet 61 when the first cover plate 41 shields the upper air inlet 51, or the first cover plate 41 does not shield the upper air inlet 51 when the second cover plate 42 shields the lower air inlet 61, so that the gas stove can be switched between two states, that is, the upper air inlet 51 is sealed and the lower air inlet 61 is sealed, by simply reciprocating.
In the present embodiment, the upper air inlet 51 is provided near the connection where the cooktop fire lid 3 is fixed to the cooktop panel 5. Specifically, as shown in fig. 1, the upper air inlet 51 is opened on the side wall surface of the drip tray. The lower air inlet 61 is located right below the upper air inlet 51, and is specifically a circular opening arranged on the stove chassis 6. When the driver 43 drives the first cover plate 41 and the second cover plate 42 to synchronously descend, the first cover plate 41 leaves the upper air inlet 51, so that the upper air inlet 51 is opened, and the lower air inlet 61 is covered by the second cover plate 42; when the driver 43 drives the first cover plate 41 and the second cover plate 42 to ascend synchronously, the second cover plate 42 leaves the lower intake vent 61, so that the lower intake vent 61 is opened, and the upper intake vent 51 is covered by the first cover plate 41.
On the basis, when the firepower state of the gas cooker is between the small fire and the large fire, the driver 43 drives the first cover plate 41 and the second cover plate 42 to move to the "middle position", that is, the positions of the first cover plate 41 and the second cover plate 42 are located between the upper covering air inlet 51 and the lower covering air inlet 61, so that the injection pipe 2 is in the state of simultaneously feeding air from the upper part and the lower part of the gas cooker in the firepower state.
Therefore, the driver 43 can drive the first cover plate 41 and the second cover plate 42 to lift synchronously, so as to achieve the purpose of switching the air inlet state of the ejector pipe 2 in fig. 2 and 3. Meanwhile, the structure for switching the air inlet state is simple, and the structural complexity and the maintenance cost of the gas cooker can be reduced.
In the present embodiment, the driver 43 of the control mechanism is a linear motor, and the linear motor can drive the first cover plate 41 and the second cover plate 42 to stay at a specific position along the vertical direction, so as to cover the upper air inlet 51 and the lower air inlet 61. Of course, other mechanical structures capable of moving in a linear direction in the prior art can also achieve the above purpose, and are not described in detail herein.
In addition, there are various proposals in the prior art as to how the control means of the present invention recognizes the thermal power level of the gas cooker and controls the drive distance of the driver 43. For example, one of them is to arrange a temperature sensor near the fire cover 3 of the gas cooker to determine the fire power state of the gas cooker by using the temperature detected by the temperature sensor, and further to adjust the covering conditions of the upper air inlet 51 and the lower air inlet 61 according to the detected temperature, so as to realize effective control of the air inlet state of the ejector pipe 2.
Example 2
The present embodiment provides a gas cooker, which has substantially the same structure and principle as those of the gas cooker provided in embodiment 1, except that: in embodiment 1, the control means must consume electric power for the purpose of adjusting the intake air state of the injection pipe 2 according to the thermal power level of the gas cooker. For a common gas cooker, generally, the power does not need to be plugged, and the structure becomes complicated by adding an electric power system into the cooker system in order to enable the control mechanism to work, so that the embodiment provides a scheme that the control mechanism can adjust the air inlet state of the injection pipe 2 according to the firepower state of the gas cooker without a power supply.
Particularly, when the gas cooker is used, the gas flow sprayed into the injection pipe 2 needs to be adjusted by means of rotation of the gas knob 8, and then the control of the firepower of the cooker is achieved. Therefore, the control mechanism of the embodiment judges the heating power state of the gas cooker by the size of the rotation angle of the gas knob 8.
As shown in fig. 5 to 7, compared to embodiment 1, the first cover plate 41 and the second cover plate 42 of the control mechanism of the present embodiment have substantially the same positional relationship with the upper air inlet 51 and the lower air inlet 61, but the first cover plate 41 and the second cover plate 42 are kept linked with the rotating shaft 81 of the gas knob 8 by the transmission unit 45.
The transmission unit 45 specifically includes a transmission combination of a plurality of gears, and a mechanism composed of a worm 46 and a connecting rod 44 (see fig. 8 specifically) for finally converting the horizontal rotation into the vertical movement.
The transmission combination of the gears can be divided into the following steps in sequence: a first gear 45a, a second gear 45b, a third gear 45c, a fourth gear 45d, and a fifth gear 45 e. Wherein, the first gear 45a is connected to the rotating shaft 81 of the gas knob 8 to rotate synchronously with the gas knob 8.
As shown in fig. 6, when the gas knob 8 rotates counterclockwise, i.e. the ignition state or switches from the low fire state to the high fire state, the sector-shaped first gear 45a drives the second gear 45b to rotate, and then the sector-shaped gear linked with the second gear 45b drives the third gear 45c on the surface of the worm 46 to rotate, so that the connecting rod 44 moves upward, and finally, the first cover plate 41 and the second cover plate 42 move upward, so that the upper air inlet 51 is closed, and the lower air inlet 61 on the cooker chassis 6 is opened.
As shown in fig. 7, when the gas knob 8 rotates clockwise, i.e. when the gas knob is switched from a big fire state to a small fire state, the movement of the first gear 45a drives the fourth gear 45d and the fifth gear 45e to rotate, and then the sector gear linked with the fifth gear 45e drives the third gear 45c on the surface of the worm 46 to rotate in the opposite direction, so that the connecting rod 44 moves downward, and finally, the first cover plate 41 and the second cover plate 42 move downward, so that the lower air inlet 61 is closed, and the upper air inlet 51 on the cooktop panel 5 is opened due to the downward movement of the first cover plate 41.
Therefore, the control mechanism in this embodiment utilizes a gear transmission manner to directly enable the rotation of the gas knob 8 to be a driving force for driving the first cover plate 41 and the second cover plate 42 to move, so that the gas cooker can realize efficient combustion in a big fire state, and solve the problem that the switch cabinet door is easy to cause flameout in a small fire state. Meanwhile, the control mechanism provided by the embodiment does not need any external energy including electric power for controlling the air inlet state of the injection pipe 2, so that the structural complexity of the cooker system is effectively simplified, and the use reliability of the gas cooker is ensured.

Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the invention, and these changes and modifications are within the scope of the invention.
