Description

Linkage system of kitchen range and smoke range

Technical Field

The utility model relates to the technical field of cooking equipment, in particular to a linkage system of a kitchen range and a smoke range.

Background

With the increasing quality of life, people pay more attention to the inconvenience of some details in daily life. For example, during cooking, a user is required to perform a series of compact operations, which may cause problems such as forgetting to turn on the smoke machine by the user during cooking. When the user finds that the cigarette maker is not turned on, the user's hand is likely to be occupied, or the cigarette maker is turned on at this time to contaminate food. In order to fill the blank, a smoke cooker linkage system is introduced in the market.

The existing smoke kitchen linkage system is generally provided with a wireless transmitting device at a kitchen range end, and a wireless receiving device at a smoke machine end. Thus, when a user adjusts the fire power (including turning on and/or off the fire power) of the kitchen range, the wireless transmitting device on the kitchen range sends out a radio signal, and the wireless receiving device of the smoke machine receives the radio signal, so that corresponding actions are executed.

The kitchen appliance is more, the signal interference and shielding are serious, and the linkage failure of the kitchen appliance and the smoke machine can occur, so that the user experience is affected.

Disclosure of utility model

In order to at least partially solve the problems of the prior art, according to one aspect of the present utility model, there is provided a cooktop comprising: the fire power regulating valve comprises a movable valve core, and the valve core is used for regulating the fire power of the kitchen range; a sound emitting assembly; and an actuating assembly coupled to and moving with the valve spool, the actuating assembly configured to act on the sound emitting assembly to cause the sound emitting assembly to emit a predetermined sound when the valve spool adjusts the fire power.

The actuation assembly acts on the sound emitting assembly to emit a predetermined sound when the user adjusts the fire. The preset sound can be detected by other devices (such as a smoke ventilator), and when the preset sound is detected by the other devices, the other devices can be automatically started, shut down or change the working state, so that manual operation of a user is not needed, and the user experience is improved. The preset sound is greatly different from the environment noise, can be simply distinguished by other devices, and is not easy to cause misoperation. The kitchen range can automatically control other devices through preset sounds without complex communication signal transmission, so that signal interference between kitchen appliances is avoided, and accurate control of other devices can be realized. The sounding component and the actuating component adopt mechanical structures, so that the reliability is high, and no additional power supply is needed.

The actuation assembly may include a first actuation assembly, the sound emitting assembly including a first sound emitting assembly, the first actuation assembly causing the first sound emitting assembly to emit a first sound when the valve spool turns on fire, wherein the predetermined sound includes the first sound.

Through making the first sound, can in time control cigarette machine linkage when the user begins the culinary art, improve user experience.

The first actuation assembly may have a first action site that causes the first sound emitting assembly to emit a first sound when the valve core turns on fire and a second action site that causes the first sound emitting assembly to emit a second sound when the valve core turns off fire, wherein the predetermined sound further includes a second sound, the first and second action sites being configured such that the first sound is different from the second sound.

The first and second sites of action may have different configurations, or may be made of different materials, etc., such that the first sound is different from the second sound.

The first and second sound emitting assemblies may be configured to emit a first sound when the valve cartridge is in the on fire state and a second sound different from the first sound when the valve cartridge is in the off fire state, the predetermined sound including the first sound and the second sound.

This allows the same actuation assembly to be used to act on different sound emitting assemblies, respectively, to emit a first sound and a second sound, respectively.

The first and second actuation assemblies are configured to provide a first sound to the first and second acoustic assemblies when the valve cartridge is in the open fire position.

This allows the same sound emitting assembly to be acted upon by different actuation assemblies to emit a first sound and a second sound, respectively.

The second sound emitting assembly may further include a second sound emitting assembly that causes the second sound emitting assembly to emit a second sound when the valve core turns off fire.

This allows for the use of different actuation assemblies to act on different sound emitting assemblies, respectively, to emit a first sound and a second sound, respectively.

The first stop member limits the first actuating assembly when the valve element is in its initial position, and releases the first actuating assembly when the valve element moves from the initial position to the impact position, so that the first actuating assembly impacts the first sound generating assembly.

On one hand, the first limiting piece can avoid the situation that the first sound is triggered by mistake, so that the smoke machine is started by mistake; on the other hand, the moment that the first actuating component breaks away from the first limiting piece can enable the first actuating component to accelerate to strike the first sounding component, so that louder sounds are emitted, and the sound is easily recognized by the smoke machine.

Illustratively, the first actuating assembly includes: a first connecting member connected to the spool; the first hammer is provided with a first sounding component which is positioned on the moving path of the first hammer; the first elastic piece is connected between the first connecting piece and the first hammer, and when the valve core is at the initial position, the first hammer is limited by the first limiting piece and is spaced from the first sounding component; when the valve core is positioned between the initial position and the impact position, the first hammer is limited by the first limiting piece and the first elastic piece is elastically deformed; and when the valve core is at the impact position, the first hammer breaks away from the first limiting piece and impacts the first sounding component.

Since most of the energy of the impact is derived from the first elastic element, the sound generated by the first elastic element is basically consistent and is not easily influenced by human factors each time the first elastic element is repeated.

The first elastic member is in a bar shape or a rod shape, and both ends of the first elastic member are connected to the first connecting member and the first hammer, respectively.

The first actuating assembly designed in this way is simple in structure and can be convenient for the design and manufacture of the first limiting piece.

The first resilient member is resiliently deformable to slide the first hammer along the surface of the first sound emitting assembly and over the first sound emitting assembly.

In order to ensure that the user can smoothly adjust the fire power, the first elastic piece can be bent and deformed, so that the first hammer can slide over the surface of the first sounding component, and the valve core can be continuously rotated.

The first limiting member is a limiting groove.

The limiting groove has a simple structure, and the valve core can reliably keep the first hammer at the initial position when the valve core is at the initial position, so that the position change of the first hammer is avoided.

Illustratively, the cooktop further includes: and the second limiting piece limits the first actuating assembly when the valve core is in the pre-closing position before returning to the initial position so as to enable the second acting position to be spaced from the first sounding assembly, and releases the first actuating assembly during the process of returning the valve core from the pre-closing position to the initial position so as to enable the second acting position to act on the first sounding assembly.

The second limiting piece has the function similar to that of the first limiting piece, and can block corresponding hammers, so that elastic deformation energy storage occurs to elastic pieces, and the first sounding component is impacted with larger force when the elastic pieces are separated from the limiting pieces.

Illustratively, the second actuating assembly includes: the second connecting piece is connected to the valve core; the second hammer, the sounding component is located on the moving path of the second hammer; and a second elastic member connected between the second connecting member and the second hammer.

Due to the presence of the second elastic member, the second hammer may be caused to strike the first sounding member with a large force, thereby increasing the loudness of the second sound, enabling the smoke machine to be easily identified.

The stove further comprises a second limiting piece, and when the valve core is in the pre-closing position before returning to the initial position, the second hammer is limited by the second limiting piece and is spaced from the sounding component; when the valve core is positioned between the initial position and the pre-fire closing position, the second hammer is limited by the second limiting piece and the second elastic piece is elastically deformed; and when the valve core is at the initial position, the second hammer is separated from the second limiting piece and impacts the sounding assembly to emit second sound.

Illustratively, when the valve core is at the initial position, the second hammer abuts against the sounding assembly, and the second elastic piece is elastically deformed under the action of the sounding assembly.

In this way, it is possible to ensure that the second sound is formed without damaging the second actuating assembly or the first sounding assembly, and without the problem of the control valve being able to be completely closed.

Illustratively, the cooktop further includes: the first limiting piece is used for limiting the first actuating assembly when the valve core is in the initial position of the valve core, and the first limiting piece releases the first actuating assembly when the valve core moves from the initial position to the impact position so that the first actuating assembly impacts on the first sound generating assembly; and the second limiting piece limits the first actuating assembly when the valve core is in the pre-fire closing position before returning to the initial position, and releases the first actuating assembly during the return of the valve core from the pre-fire closing position to the initial position so that the first actuating assembly impacts the second sounding assembly.

In this way, the same actuation assembly may be utilized to act on different sound emitting assemblies, respectively, to emit a first sound and a second sound, respectively. The loudness of the second sound may also be increased.

The first and second restraints are illustratively located between the first and second sound emitting assemblies.

In this way, the structure can be made compact.

Illustratively, the first actuating assembly includes: a first connecting member connected to the spool; the first hammer and the second hammer are arranged on the moving path of the first hammer; the first elastic piece is connected between the first connecting piece and the first hammer, and when the valve core is in the pre-fire closing position, the first hammer is limited by the second limiting piece and is spaced apart from the second sounding component; when the valve core is positioned between the initial position and the pre-fire closing position, the first hammer is limited by the second limiting piece and the first elastic piece is elastically deformed; and when the valve core is at the initial position, the first hammer breaks away from the second limiting piece and impacts the second sounding component.

Illustratively, the predetermined sound includes: the first sound, the actuation assembly is configured to act on the sound emitting assembly when the valve core turns on fire power to cause the sound emitting assembly to emit the first sound.

The first sound can be emitted by the kitchen range to control the automatic opening of the smoke machine.

Illustratively, the predetermined sound includes: the second sound, the actuation assembly is configured to act on the sound emitting assembly when the valve core turns off fire, causing the sound emitting assembly to emit the second sound.

The first sound and the second sound are different. The difference between the two sounds can be identified by the smoke machine, so that other control of the smoke machine is realized by utilizing the second sound.

According to another aspect of the present utility model, there is also provided a range linkage system comprising: the cooktop described above; the smoke machine comprises a microphone, a control module and a smoke sucking component, wherein the microphone is used for receiving sound in the working environment of the smoke machine; the control module is connected with the microphone and the smoking component and is used for identifying preset sound in sound received by the microphone and controlling the smoking component to execute operation corresponding to the preset sound when the preset sound is identified.

In the smoke cooker linkage system, the smoke machine and the kitchen range can be automatically linked, and the user experience is optimized. The stove can emit a preset sound when the fire power is regulated by a user and the actuating component acts on the sounding component. The smoke machine can recognize that the preset sound is automatically started, shut down or change the working state, manual operation of a user is not needed, and user experience is improved. The preset sound is greatly different from the environment noise, can be simply distinguished by the smoke machine, and is not easy to cause misoperation. The kitchen range can automatically control the smoke machine through preset sound without complex communication signal transmission, so that signal interference between kitchen appliances is avoided, and accurate control of the smoke machine can be realized.

Illustratively, the control module comprises a first controller and a second controller interconnected, the first controller being coupled to the microphone, the second controller being coupled to the smoking assembly, the first controller being configured to identify a first sound in sounds received by the microphone and to control the second controller to enter an operational state when the first sound is identified, wherein the predetermined sound comprises the first sound; the second controller is used for controlling the smoking assembly to start when the smoking assembly enters the working state.

Therefore, the smoke cooker linkage system has lower energy consumption on the premise of ensuring normal use of users. In addition, the first controller and the second controller in the control module are arranged separately, and when one of the controllers is damaged, only the damaged controller can be replaced, so that the maintenance cost is saved.

The smoke machine further comprises an input device connected with the second controller, wherein the input device is used for receiving a first instruction of a user, and the first instruction is used for triggering the second controller to start and enter a standby state.

In the technical scheme, the second controller can be controlled to enter the standby state through the input device of the smoke machine. The second controller is triggered by the input device, so that the reliability is stronger, the habit of a user is met, and better experience can be brought to the user.

Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the utility model. However, it will be understood by those skilled in the art that the following description illustrates preferred embodiments of the utility model by way of example only and that the utility model may be practiced without one or more of these details. Furthermore, some technical features that are known in the art have not been described in detail in order to avoid obscuring the utility model.

According to one aspect of the present utility model, a cooktop is provided. The cooktop may include a fire adjustment valve that includes a movable valve spool for adjusting the fire of the cooktop. The cooktop may be a gas cooker, an electromagnetic cooker, or the like, for example, and the fire power adjustment valve may be a gas fire power adjustment valve or an electronic fire power adjustment valve, respectively. The valve core of the fire power regulating valve can regulate fire power in a rotary, translational or combined mode. Typically, the fire power control valve further includes a valve housing, and the valve spool is movably disposed within the valve housing. The valve core is connected with a valve rod which extends out of the valve shell, so that the valve core can be operated outside the fire power regulating valve through the fire power regulating valve rod. Of course, the valve element may have a portion extending beyond the valve housing for operational use. Or in other embodiments the valve core may be operated outside the valve housing under non-contact forces such as magnetic forces or the like, in which case the valve core may not be in direct contact with an operating member outside the valve housing.

As shown in fig. 1, the fire power control valve 110 is a gas fire power control valve. A valve body (not shown) of the fire power adjusting valve 110 is connected to the valve stem 111, and the valve body can be rotated with the rotation of the valve stem 111, thereby adjusting the fire power of the kitchen range. The cooktop may also include a sound emitting assembly 120 and an actuating assembly 130, the actuating assembly 130 may be connected to and move with the valve cartridge through a valve stem 111. In other embodiments not shown, the actuation assembly may also be directly connected to the spool. Or alternatively, the actuating assembly may be non-contact connected to the valve spool by magnetic force. The actuating assembly 130 is only required to be able to move with the spool. The actuation assembly 130 is configured to act on the sound emitting assembly 120 when the valve cartridge adjusts the fire power to cause the sound emitting assembly 120 to emit a predetermined sound. Illustratively, the actuating assembly 130 may include a hammer made of metal, ceramic, wood, rubber, or the like. As the actuation assembly 130 moves, the hammer may strike the sound emitting assembly 120 or rub against the sound emitting assembly 120, thereby emitting a sound. The sounding assembly 120 may include a tuning fork, bell, etc. that can emit a predetermined sound. The predetermined sound may include a sound audible to the human ear or may include a sound inaudible to the human ear. The actuation assembly 130 may cause the sound emitting assembly 120 to emit the predetermined sounds described above. In the embodiment shown in fig. 1, the actuating assembly 130 may preferably include a hammer 132. When the fire power is adjusted by the valve spool, the hammer 132 follows the valve spool and strikes the sounding assembly 120 to make a predetermined sound.

In the application, the sounding component 120 and the actuating component 130 are arranged on the kitchen range, and when the fire power is regulated by a user, the actuating component 130 acts on the sounding component to generate preset sound. The preset sound can be detected by other devices (such as a smoke ventilator), and when the preset sound is detected by the other devices, the other devices can be automatically started, shut down or change the working state, so that manual operation of a user is not needed, and the user experience is improved. The preset sound is greatly different from the environment noise, can be simply distinguished by other devices, and is not easy to cause misoperation. The kitchen range can automatically control other devices through preset sounds without complex communication signal transmission, so that signal interference between kitchen appliances is avoided, and accurate control of other devices can be realized. The sounding component 120 and the actuating component 130 adopt mechanical structures, so that the reliability is high, and no additional power supply is needed.

Illustratively, as shown in fig. 1, the actuation assembly 130 may include a first actuation assembly 130a and the sound emitting assembly 120 may include a first sound emitting assembly 121. "adjusting the stove fire" may include one or more of turning on fire, turning off fire, etc. Wherein, when the linkage operation of the smoke kitchen range which is most needed by a user is to turn on or off the fire power, the smoke kitchen range can be correspondingly turned on or off. Accordingly, the first actuating assembly 130a causes the first sound emitting assembly 121 to emit a first sound when the valve spool turns on fire, wherein the predetermined sound includes the first sound. Preferably, the first sound may be used to control the smoke machine to turn on smoke. Through making the first sound, can in time control cigarette machine linkage when the user begins the culinary art, improve user experience.

Illustratively, the cooktop may further include a first stop 141, the first stop 141 limiting the first actuation assembly 130a when the spool is in its initial position. The initial position may be a position where the spool is when the fire power control valve 110 is in the closed state. The first stopper 141 releases the first actuating assembly 130a when the spool moves from the initial position to the striking position so that the first actuating assembly 130a strikes the first sounding assembly 121. On the one hand, the first limiting part 141 can avoid the false triggering of the first sound, which leads to the false starting of the smoke machine; on the other hand, the moment when the first actuating assembly 130a is separated from the first limiting member 141 can make the first actuating assembly 130a impact on the first sounding assembly 121 in an accelerating manner, so that a louder sound is emitted to be easily recognized by the smoke machine.

For knob-type fire power regulating valves commonly used in current gas cookers, the initial rotation angle of the valve element when in the initial position is designated as θ ₀, and θ ₀ is 0 degrees, as shown in fig. 9. In the counterclockwise rotation of the spool, the rotation angle of the spool may sequentially reach the first rotation angle θ ₁, the second rotation angle θ ₂, and the third rotation angle θ ₃. In one embodiment, when the rotation angle of the valve element is smaller than the first rotation angle θ ₁, no fuel gas has yet passed through the fire control valve 110. When the valve body rotates a small amount due to manufacturing tolerances or the like, the fire control valve 110 does not pass fuel gas yet. The first rotation angle θ ₁ is sized in relation to manufacturing tolerances, and the first rotation angle θ ₁ may be 20 degrees to 30 degrees based on commercial cooktops. When the rotation angle of the valve core is between the first rotation angle θ ₁ and the second rotation angle θ ₂, the amount of gas passing through the fire power adjusting valve 110 is large, and the burner of the stove can form inner flame and outer flame, i.e. big fire. Empirically, the second rotation angle θ ₂ may be between 120 degrees and 135 degrees. The third rotation angle θ ₃ is a maximum angle at which the spool can rotate, and empirically, the third rotation angle θ ₃ can be between 165 degrees and 175 degrees. When the rotation angle of the spool exceeds the second rotation angle θ ₂ and is not greater than the third rotation angle θ ₃, the amount of fuel gas passing through the fire power adjustment valve 110 is small, and only an inner flame, i.e., a small fire, is formed.

The instant of ignition by a user using such a knob-type fire control valve 110 tends to rotate the valve spool to a position generally between 60-120 degrees, and then rotate the knob to the desired fire level as needed. Based on this, the rotation angle of the spool when in the impact position may be less than or equal to 60 degrees. For the current common gas cookers, the rotation angle of the valve core is in the range of 0- ₁, and the ignition cannot be successfully performed. Therefore, the rotation angle of the valve element at the striking position can be set in the range of 0- θ ₁. As described above, the first rotation angle θ ₁ may be any value in the range of 20 degrees to 30 degrees. Preferably, the rotation angle of the spool in the impact position is set to be less than 20 degrees. In this way, it can be ensured that the first stop 141 can release the first actuating assembly 130a before the user successfully ignites, so that the first actuating assembly 130a can strike the first sounding assembly 121, regardless of the user's ignition habit and the manufacturing tolerances of the hob.

The disengagement of the first actuating assembly 130a from the first stop 141 may be accomplished by elastic deformation of either of the first actuating assembly 130a and the first stop 141. Or the detachment of the first actuating assembly 130a from the first stop 141 may be accomplished entirely by virtue of the compression of the two, resulting in a reduced assembly gap with the cooktop. In any manner, the first actuating assembly 130a may be disengaged from the first stopper 141 after receiving a sufficient force, thereby striking the first sounding assembly 121.

Illustratively, as shown in FIG. 1, the first actuating assembly 130a may include a first connector 131. The first connector 131 may be connected to the valve cartridge. In the illustrated embodiment, the first connector 131 is connected to the valve cartridge by a valve stem 111. The first actuating assembly 130a may further include a first hammer 132 and a first elastic member 133. The first sounding assembly 121 is located on the moving path of the first hammer 132, and the first elastic member 133 is connected between the first link 131 and the first hammer 132. When the spool is in the initial position, the first hammer 132 is restrained by the first restraining member 141 and spaced apart from the first sounding member 121. As shown in fig. 2A, when the spool rotates counterclockwise between the initial position and the striking position, the first hammer 132 is restrained by the first restraining member 141, causing the first elastic member 133 to elastically deform. As shown in fig. 2B, when the spool is in the striking position, the first hammer 132 is disengaged from the first stopper 141 and strikes the first sound emitting assembly 121. The first elastic member 133 may include one or more of a spring, a spring piece, and a block made of an elastic material such as rubber.

When the user turns on the fire, rotating the control valve counterclockwise applies a moment to the first elastic member 133 because the first hammer 132 is blocked by the first stopper 141. The first elastic member 133 is elastically deformed accordingly to store elastic potential energy. Meanwhile, due to the elastic deformation of the first elastic member 133, the contact position of the first hammer 132 and the first stopper 141 is gradually changed, and when the valve core is at the striking position, the first hammer 132 is separated from the blocking of the first stopper 141, and the elastic potential energy stored in the first elastic member 133 accelerates the first hammer 132 to strike the first sounding component 121, thereby making a loud sound. In the illustrated embodiment, the first stopper 141 may be a stopper groove. The limit grooves limit the first hammer 132 at least in both directions toward which the fire is turned on and off. The limiting groove has a simple structure, and the first hammer 132 can be reliably kept at the initial position when the valve core is at the initial position, so that the position change is avoided. Of course, the first limiting member 141 may also include a bevel block having a bevel. The ramp block may limit the first hammer 132 only in the direction toward the fire on. When the spool moves, the first elastic member 133 may be pressed by the inclined surface to be deformed. When the spool is in the striking position, the first hammer 132 is disengaged from the first stopper 141 and strikes the first sounding assembly 121. When the user turns off the fire, the first hammer 132 returns again to the restricting position of the first stopper 141 to trigger again. Since most of the energy of the impact is derived from the first elastic member 133, the sound generated by the impact is substantially uniform and not easily affected by human factors each time it is repeated. In the illustrated embodiment, the first elastic member 133 is curved when elastically deformed, and in other embodiments not shown, the first elastic member 133 may be stretched or compressed in a direction perpendicular to the movement direction of the first hammer 132, depending on the structure of the first elastic member 133.

The first elastic member 133 is in the shape of a bar or rod, and both ends of the first elastic member 133 are connected to the first connecting member 131 and the first hammer 132, respectively, as an example. The first actuating assembly 130a thus designed is simple in structure and can facilitate the design and manufacture of the first stopper 141. Illustratively, the first resilient member 133 is resiliently deformable to slide the first hammer 132 along the surface of the first sound emitting assembly 121 and over the first sound emitting assembly 121. With continued reference to FIG. 3, the maximum possible rotation of the valve core is 150 degrees as the user adjusts the stove fire. As described above, the rotation angle of the spool from the initial position to the striking position is much smaller than the above-described maximum rotation angle, and therefore, in order to ensure that the user can smoothly adjust the fire power, the first elastic member 133 can be bent and deformed so that the first hammer 132 can slide over the surface of the first sounding member 121, thereby continuing to rotate the spool.

In the above embodiment, the predetermined sound includes a first sound, and the range may be controlled to be automatically turned on by making the range emit the first sound. Alternatively, the predetermined sound may include a first sound and a second sound, the first sound and the second sound being different. The difference between the two sounds can be identified by the cigarette machine, so that other control on the cigarette machine, such as automatic closing of the cigarette machine, is realized by utilizing the second sound. The first sound and the second sound may differ in at least one of loudness, pitch, and hue, etc. Illustratively, the first sound and the second sound may differ significantly in loudness due to the different forces that the actuation assembly 130 exerts on the sound emitting assembly; the actuation assembly 130 may also act on different sound emitting assemblies to cause the first and second sounds to have different pitch and tone, in other words, the first and second sounds may have different pitch, due to the difference in the structure of the different sound emitting assemblies; the first sound and the second sound may have distinct tone differences due to different materials of different sound emitting components, and/or different materials of different actuating components 130 or different materials of different acting portions of the same actuating component 130. The timbre is determined by the relative intensities and distribution of the harmonic components. The relative intensity and distribution then determines the rich or lean feel of the sound. For example, brass bell and iron bell may be used as different sounding components, which may emit the same tone, but may differ significantly in tone. For another example, striking the same bell with different objects may produce different sounds. This is because objects striking the bell have different hardness, shape and density, which affect the harmonic distribution and energy transfer of sound, and different striking objects cause different vibration patterns and overtone harmonic generation on the bell, thereby changing the final sound characteristics.

A number of different embodiments capable of emitting different first and second sounds will be described in detail below with reference to the drawings.

Fig. 3A-3B illustrate an embodiment in which the same sound emitting assembly is acted upon by the same actuation assembly 130 and emits a first sound and a second sound, respectively.

The first actuation assembly 130a' has a first site of action 132a and a second site of action 132b. The first action portion 132a causes the first sound emitting member 121 to emit a first sound when the valve spool turns on the fire power. The second action portion 132b causes the first sound emitting assembly 121 to emit a second sound when the valve core turns off fire. Typically, the movement process of the first actuating assembly 130a ' during the time when the spool is returned from the maximum rotation angle to the initial position is exactly opposite to that of the first actuating assembly 130a ' during the time when the spool is returned from the maximum rotation angle to the initial position, and thus the first acting portion 132a and the second acting portion 132b may be disposed opposite to each other along the movement direction of the first actuating assembly 130a ', and thus the first acting portion 132a may be made to act on the first sounding assembly 121 when the fire is turned on and the second acting portion 132b may be made to act on the first sounding assembly 121 when the fire is turned off. The first actuating assembly 130a' may have substantially the same structure as the first actuating assembly 130a of any of the embodiments described above. Accordingly, the same reference numerals are used for the same or similar structures of the first actuating assembly 130a' as the first actuating assembly 130 a. Only the differences will be described in detail below.

For example, the first action portion 132a and the second action portion 132b may be located on the first hammer 132. The first and second action sites 132a, 132b have different configurations such that the first sound is different from the second sound.

In one set of embodiments, the first and second sites of action 132a, 132b may be made of different materials. The first hammer 132 may be formed by splicing two halves made of different materials. Half may form the first site of action 132a and the other half form the second site of action 132b. Optionally, at least one of the first and second sites 132a, 132b may be configured as a surface lamina. In comparison with the embodiment shown in fig. 1, a surface thin layer having a material different from that of the first hammer 132 may be formed on one side surface of the first hammer 132 to form the first action portion 132a or the second action portion 132b; while the other side surface of the first hammer 132 may be exposed to directly act on the first sounding member 121. Alternatively, surface thin layers of different materials may be formed on both side surfaces of the first hammer 132, respectively, to form the first action portion 132a or the second action portion 132b, respectively.

In another set of embodiments, the first and second active sites 132a, 132b may be configured to have different contact areas with the first sound emitting assembly 121, thereby emitting sounds of different loudness. Alternatively, the area of the first site of action 132a may be different from the area of the second site of action 132 b. For example, one of the first and second sites of action 132a, 132b may be sharp, while the other of the first and second sites of action 132a, 132b may be rounded. Alternatively, one of the first and second action portions 132a and 132b may be smooth and the other surface may be relatively rough, so that the contact areas of the first and second action portions 132a and 132b, respectively, with the first sound generating member 121 may be different.

In order to increase the force of the second action portion 132b on the first sound emitting member 121 when the fire power is turned off, a loud sound that is easily recognized by the smoke machine is emitted. A second stop 142 may be provided such that when the valve spool is in the pre-fire position prior to returning to its initial position, the first actuating assembly 130a' is stopped by the second stop 142 such that the second active site 132b is spaced from the first acoustic assembly 121. The angle of rotation of the valve spool in the pre-fire position may be greater than the angle of rotation of the valve spool in the strike position, as shown in fig. 9. In the illustrated embodiment, the rotation angle of the spool in the pre-fire position is in the range of 0- θ ₁, and in other embodiments not shown, the rotation angle of the spool in the pre-fire position may be equal to θ ₁ or slightly greater than θ ₁. Preferably, the rotation angle of the valve core is in the range of 0- θ ₁ when the second action site 132b acts on the first sound emitting assembly 121, so as to ensure that the stove has been turned off. Referring back to fig. 3B, the second stop 142 releases the first actuating assembly 130a' during return of the valve spool from the pre-fire position to the initial position to cause the second apply portion 132B to act on the first acoustic assembly 121. The moment the first actuating member 130a' is disengaged from the first stop 141 can cause the second impact portion 132b to accelerate the impact on the first sounding member 121, thereby increasing the loudness of the sound. When the spool is in its initial position, the first actuating assembly 130a' may return to a state of being restrained with the first restraining member 141.

Fig. 4 shows an embodiment in which the same actuation assembly is used to act on different sound emitting assemblies to emit a first sound and a second sound, respectively. As shown in fig. 4, the actuation assembly 130 may include a first actuation assembly 130a ". The sound emitting assembly 120 may include a first sound emitting assembly 121 and a second sound emitting assembly 122. The first actuation assembly 130a "may cause the first sound emitting assembly 121 to emit a first sound when the valve spool turns on fire and cause the second sound emitting assembly 122 to emit a second sound when the valve spool turns off fire. The first actuating assembly 130a "may have substantially the same structure as the first actuating assembly 130a of any of the embodiments described above. When the spool rotates counterclockwise from the initial position, the first actuating assembly 130a″ may act on the first sounding assembly 121, thus sounding a first sound. When the spool returns to the original position, in one embodiment, the first actuation assembly 130a "acts on the first sound emitting assembly 121 and then on the second sound emitting assembly 122. That is, the second sound includes two sequentially emitted sounds respectively acting on the first sound emitting assembly 121 and the second sound emitting assembly 122. In another embodiment, the first actuating assembly 130a″ may have a first hammer 132″ different from the first hammer 132. For example, the center-to-center distance of the first sound emitting assembly 121 to the valve stem 111 may be greater than the center-to-center distance of the second sound emitting assembly 122 to the valve stem 111. The first actuating assembly 130a″ may have a third action site 132c, the third action site 132c acting on the first acoustic assembly 121 when the spool returns to the original position. The third site of action 132c may be made of a more resilient material, such as a sponge or the like. Thus, the third action portion 132c passes through the first sounding member 121 hardly causes the first sounding member 121 to sound. When the valve spool returns to the initial position, other stiffer portions of the first actuation assembly 130a″ may act on the second sound emitting assembly 122, causing the second sound emitting assembly 122 to emit a second sound.

Fig. 5 shows an embodiment in which different actuation assemblies are used to act on the same sound emitting assembly, respectively, to emit a first sound and a second sound, respectively. In contrast to the embodiment shown in fig. 1, the actuation assembly 130 includes a second actuation assembly 130b in addition to the first actuation assembly 130a. The sound emitting assembly 120 may include a first sound emitting assembly 121. The first actuation assembly 130a causes the first sounding assembly 121 to sound a first sound when the valve spool turns on fire and the second actuation assembly 130b causes the first sounding assembly 121 to sound a second sound when the valve spool turns off fire. When the valve core is on fire, the first actuating assembly 130a passes through the first limiting member 141, and when the valve core reaches the striking position, the first hammer 132 can strike the first sounding assembly 121 with a larger force, thereby making a first sound.

When the spool rotates in the direction of the closing force, the second actuating assembly 130b impacts the first sounding assembly 121 as the spool returns to the initial position. But before the second actuating assembly 130b hits the first sound generating assembly 121, the first actuating assembly 130a may hit the first sound generating assembly 121 first, and then the second sound may include two hits. Of course, the first actuating assembly 130a may also have the same structure as the first actuating assembly 130a″ shown in fig. 4 such that the first actuating assembly 130a emits little sound when passing through the first sounding assembly 121. In this case, it is necessary that the first hammer 132 and the second hammer 136 can emit different sounds when striking the first sound emitting assembly 121, respectively. For example, the first hammer 132 and the second hammer 136 may be made of different materials, thereby producing sounds of different timbres and/or tones. For example, the areas of the first hammer 132 and the second hammer 136 acting on the first sound emitting member 121 may be different, thereby emitting different sounds.

In addition, it should be noted that the second actuating assembly 130b may strike the first acoustic assembly 121 after the first actuating assembly 130a passes through the first acoustic assembly 121 and before the valve element reaches the initial position, and does not need to wait for the valve element to reach the initial position to strike the first acoustic assembly 121.

Illustratively, the second actuating assembly 130b may include a second link 135, a second hammer 136, and a second elastic member 137, the second link 135 may be connected to the spool, the first sounding assembly 121 is located on a moving path of the second hammer 136, and the second elastic member 137 is connected between the second link 135 and the second hammer 136. Due to the presence of the second elastic member 137, the second hammer 136 may be caused to strike the first sounding member 121 with a large force, thereby increasing the loudness of the second sound, enabling the smoke machine to be easily recognized.

In addition, the second elastic member 137 can prevent the valve core from being unable to strike the first sound generating assembly 121 when returning to the original position, in consideration of the problem of assembly tolerance. Illustratively, when the spool is in the initial position, the second hammer 136 can abut against the first sound emitting assembly 121, and the second elastic member 137 is elastically deformed by the first sound emitting assembly 121. To ensure that the valve spool reaches the initial position, the second hammer 136 can strike the first sounding assembly 121, and therefore, during the course of turning off the fire, the second hammer 136 has struck the first sounding assembly 121 before reaching the initial position. When the initial position is reached, the second hammer 136 is blocked by the first sounding member 121 from continuing to move, and at this time, the second elastic member 137 can be elastically deformed. In this way, it is possible to ensure that in the case of forming the second sound, damage to the second actuating assembly 130b or the first sounding assembly 121 is avoided, and also the problem that the control valve cannot be completely closed is avoided.

Illustratively, the cooktop may further include a second stop 142, as shown in FIG. 6, with the second hammer 136 being stopped by the second stop 142 and spaced from the first sound assembly 121 when the valve spool is in the pre-fire position prior to returning to its initial position. When the valve core is between the initial position and the pre-close position, the second hammer 136 is limited by the second limiting piece 142 and the second elastic piece 137 is elastically deformed. When the spool is in the initial position, the second hammer 136 is disengaged from the second stopper 142 and strikes the first sounding assembly 121 to emit a second sound. The second limiting member 142 has a similar function to the first limiting member 141, and can block the corresponding hammer, so that the elastic members are elastically deformed to store energy, and the first sounding component 121 is impacted with a larger force when the elastic members are separated from the limiting members. The second limiting member 142 will not be described herein.

Illustratively, referring back to fig. 4, a second stop 142 may also be included, the second stop 142 stopping the first actuating assembly 130a "when the spool is in the pre-fire position prior to returning to its initial position, and the second stop 142 releasing the first actuating assembly 130a" during the return of the spool from the pre-fire position to the initial position to cause the first actuating assembly 130a "to impinge on the second sound emitting assembly 122. In this way, the loudness of the second sound can be increased. Illustratively, the first and second restraints 141, 142 may be located between the first and second sound emitting assemblies 121, 122. In this way, the structure can be made compact.

It should be noted that the second limiting member 142 may limit the actuating assembly only along the direction of returning to the initial position. The reason for this is that the pre-fire position limited by the second limiting member 142 is only the instantaneous position of the valve core, and the valve core will not stay at this position, so the second limiting member 142 only needs to block the first actuating assembly 130a″ before it hits the second sounding assembly 122, so as to store energy and increase the hitting sound.

The first limiting member 141 may be integral with the second limiting member 142, or may be provided separately. Referring back to fig. 4, an integral first and second stop 141 and 142 may be secured between the first and second sound emitting assemblies 121 and 122. The design structure is simple, and the occupied space is relatively small.

Fig. 7 shows an embodiment in which different actuation assemblies are used to act on different sound emitting assemblies, respectively, to emit a first sound and a second sound, respectively. In contrast to the embodiment shown in fig. 5, the sound emitting assembly 120 comprises a second sound emitting assembly 122 in addition to the first sound emitting assembly 121. The first actuating assembly 130a causes the first sound emitting assembly 121 to emit a first sound when the valve spool turns on fire. The second actuation assembly 130b causes the second sound emitting assembly 122 to emit a second sound when the valve spool turns off fire.

As shown in fig. 7, the second hammer 136 can be abutted against the second sounding assembly 122 when the spool is in the initial position; and during the return of the spool from the pre-fire position to the initial position, the second hammer 136 can strike the second sound emitting assembly 122 to emit a second sound. The second actuating assembly 130b' may have the same or similar structure and operation as the second actuating assembly 130b described in fig. 5, and will not be further described herein for the sake of brevity.

Illustratively, the cooktop may also include a second stop 142, as shown in FIG. 8, with the second hammer 136 being stopped by the second stop 142 and spaced from the second sound emitting assembly 122 when the valve spool is in the pre-fire position prior to returning to its initial position. When the valve core is between the initial position and the pre-close position, the second hammer 136 is limited by the second limiting piece 142 and the second elastic piece 137 is elastically deformed. When the spool is in the initial position, the second hammer 136 disengages the second stopper 142 and strikes the second sounding assembly 122 to emit a second sound. The second limiting member 142 has a similar function to the first limiting member 141, and can block the corresponding hammer, so that the elastic members can be elastically deformed to store energy, and the second sounding assembly 122 can be impacted with a larger force when the elastic members are separated from the limiting members. The second limiting member 142 will not be described herein.

In the above described embodiments, the first sound is emitted when the stove fire is turned on. Alternatively, the actuating assembly and the sounding assembly corresponding to the first sound can be omitted, and only the second sound can be emitted when the stove fire is turned off. The various actuation and sound emitting components that emit the second sound may employ any of the embodiments described above, which will not be described in detail herein.

According to another aspect of the present utility model there is provided a range linkage system comprising any of the ranges mentioned above and a range. The range hood includes a microphone, a control module, and a smoking assembly. Wherein the microphone is used for receiving sound in the working environment of the smoke machine. The microphone may include a condenser microphone, a moving coil microphone, etc., and may convert sound into an electrical signal. The control module is connected with the microphone and the smoking component and is used for identifying preset sound in sound received by the microphone and controlling the smoking component to execute operation corresponding to the preset sound when the preset sound is identified. For example, the control module of the smoke machine may be used to control the activation of the smoking assembly according to the activation sound from the microphone, or to control the smoking assembly to perform a corresponding action according to other sounds. The predetermined sound may include a bell sound. The control module may include a memory. The memory stores data information corresponding to a predetermined sound. When the control module compares the sound received from the sound transducer with the data information stored in the memory. When the comparison result shows that the currently received sound is a preset sound, completing actions such as starting up; when the comparison result indicates that the currently received sound is not a predetermined sound, for example, the user's voice, no action is performed. In summary, the control module may identify sounds, such as a predetermined sound that distinguishes ambient noise from cooktops, thereby controlling the smoking components of the range based on the identified sounds. It will be appreciated that the control module may perform its functions based on any existing or future developed voice recognition algorithm, as the utility model is not limited in this regard. Preferably, the control module may be configured to filter the sound received by the sub-microphone to remove noise from the sound. This facilitates recognition of the sound, and even if the volume of the sound is small, a predetermined sound therein can be accurately recognized. The predetermined sounds generated by the cooktop may include one or more, including for example a first sound and/or a second sound, and the control module of the smoke machine may control the smoking assembly to perform different actions, such as starting and stopping the operation, depending on whether the identified sound is the first sound or the second sound. The control module may be implemented using a chip. Such as a programmable gate array (FPGA), a Micro Control Unit (MCU), a Programmable Logic Controller (PLC), etc. The smoking assembly may include a fan, impeller in the scroll, etc. for performing a smoking function. When the fan drives the impeller to rotate, a certain negative pressure is formed in the air inlet area, and the smoking function is realized through the drainage of the smoke collecting cavity. The control module may be coupled to the fan of the smoking assembly, thereby controlling the fan to perform operations such as starting, stopping, or adjusting the operating range based on sound from the microphone.

Fig. 10 shows a schematic block diagram of a range linkage system according to an embodiment of the utility model. As shown in fig. 10, the control module of the range hood in the range linkage system may include a first controller and a second controller that are connected to each other, the first controller being connected to the microphone and the second controller being connected to the smoking assembly. The first controller and the second controller may be separately provided and implemented by different chips or the like. The first controller is used for identifying a first sound in sounds received by the microphone and controlling the second controller to enter an operating state when the first sound is identified, wherein the preset sound comprises the first sound. The second controller is used for controlling the smoking assembly to start when the smoking assembly enters the working state. The first controller may be in an operating state all the time. The first controller may receive the sound signal from the microphone at any time and recognize the sound signal. The voice recognition of the first controller may be implemented by any existing or future developed deep learning algorithm or recurrent neural network, etc. The first controller may include a commercially available voice recognition module. The voice recognition module on the market is accurate in recognition, and is good in mass production cost and reliability, and extra research and development cost is not required. The first controller may be used to recognize sounds received by the microphone and communicate with the second controller through a general purpose input output interface (GPIO) or serial port. The first controller recognizes the first sound received by the microphone, sends first data to the second controller through the serial port, and enters an operating state and simultaneously controls the smoking assembly to be started after the second controller receives the first data. It is understood that the second controller may be in an off state or a standby state before receiving the first data. The second controller may be the main controller of the range hood. The state of the extractor can be described in terms of the state of the second controller. In other words, when the second controller is in the shutdown state, the smoke machine may be simply referred to as being in the shutdown state. When the second controller is in the standby state, the smoke machine can be simply called as being in the standby state. When the second controller is in the working state, the second controller can be simply called as the smoke machine is in the working state. After the second controller controls the activation of the smoking assembly, if the first data is received again from the first controller, no further action may be performed and the smoking assembly remains in operation. In other words, after the second controller is in control of the activation of the smoking assembly, it may disregard the first data input by the first controller. The second controller may include modules such as an intelligent control module, a fan driving module, etc., and may automatically control the operation state of the fan according to the data acquired from the first controller.

In the above technical solution, the control module includes a first controller and a second controller that are interconnected. The first controller is used for voice recognition and triggering the second controller based on the recognized voice; the second controller is used for controlling the smoking assembly to start based on the sound recognized by the first controller under the triggering of the first controller. In the technical scheme, the second controller can be kept in a shutdown or standby state in a longer period of time when the smoke machine is not in operation, and the first controller is always in an operating state. In particular, the second controller may consume more power than the first controller dedicated to voice recognition. Therefore, the smoke cooker linkage system has lower energy consumption on the premise of ensuring normal use of users. In addition, the first controller and the second controller belong to a computing device, are more fragile compared with simple mechanical components, are arranged separately, and can only be replaced when one of the first controller and the second controller is damaged, so that the maintenance cost is saved.

The smoke machine further comprises an input device connected with the second controller, wherein the input device is used for receiving a first instruction of a user, and the first instruction is used for triggering the second controller to start and enter a standby state. The input device may be a key or the like provided on the housing of the range hood. The second controller can enter the standby state from the power-off state by pressing a key by a user. In one example, when the second controller is in the standby state, the second controller may be brought into the operating state by the user inputting the start-up instruction again using the input device. Alternatively, as described above, when the second controller is in the standby state, the first controller may input the first data to the second controller to bring the second controller into the operation state from the standby state.
