Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description illustrates only a preferred embodiment of the invention and that the invention may be practiced without one or more of these details. In addition, some technical features that are well known in the art are not described in detail in order to avoid obscuring the present invention.

The utility model provides an adjusting device for cooking utensils. The device can be firmly installed on the panel 100 of the kitchen range through the magnetic attraction force of the ignition knob 200 and the valve body 310 inside the kitchen range. When the user uses the stove, the ignition knob 200 can be attached to the panel 100, and the stove can be switched on and off and the fire power can be adjusted by manually operating the ignition knob 200. When the user does not use or needs to clean the cooker panel 100, the user can conveniently take the ignition knob 200 off the panel 100 to clean the panel 100. The adjusting device can be used for a gas stove. The adjustment device can also be used for induction cookers, if possible. The structure of the adjusting device for adjusting the fire part of the cooking appliance is already known in the art, and the improvement point of the invention is not in this, therefore, the structure of this part will not be described in detail.

In fig. 1 is shown an adjustment device according to an embodiment of the invention, which in use is mounted to a hob panel 100. The principles of the present invention will be described with reference to the drawings.

The adjustment means may include an ignition knob 200 and an adjustment valve 300. In use, ignition knob 200 is positioned above cooktop panel 100 and regulating valve 300 is positioned below cooktop panel 100.

The ignition knob 200 may include a first magnetic body 210. The regulator valve 300 may include a valve body 310, a valve stem 320, and an electromagnet 330. The first magnetic member 210 may be a permanent magnet, or may be a magnetic member that can be attracted by a permanent magnet. The permanent magnet is a permanent magnet, and includes a natural magnet (magnetite), an artificial magnet (alnico), and the like. The magnetic member is an object that is formed of a ferromagnetic material such as transition element iron, cobalt, nickel, or an alloy thereof and can be attracted by a permanent magnet. The magnetic member can be magnetized under the action of a magnetic field and can be demagnetized after the magnetic field is removed.

Preferably, the first magnetic body 210 is a permanent magnet. Since the permanent magnet can generate a larger magnetic attraction force with the electromagnet 330 than the magnet, the reliability is stronger in the process of adjusting the adjusting valve 300 by the ignition knob 200.

The ignition knob 200 may also include a knob base 220. The first magnetic body 210 may be disposed on the knob base 220. In the illustrated embodiment, the first magnetic body 210 may be disposed at the bottom of the knob base 220, so that the first magnetic body 210 can directly attract the regulating valve 300 only through the cooktop panel 100. In other embodiments not shown, the first magnetic body 210 may also be disposed on top of the knob base 220 or in the knob base 220. The installation manner of the first magnetic substance 210 shown in the figure is only exemplary, and therefore does not constitute a limitation of the present invention, as long as the first magnetic substance 210 can provide a sufficiently large magnetic attraction force to drive the regulating valve 300 below the panel 100 to regulate the fire power.

Additionally, the ignition knob 200 may also include a knob housing 230. Illustratively, the knob housing 230 may be an open-bottomed cylinder, as shown in fig. 1. The first magnetic body 210 and the knob base 220 are accommodated in the knob housing 230. The knob base 220 is connected to the knob housing 230. The knob housing 230 protects the first magnetic body 210 and the knob base 220. The user can rotate the first magnetic member 210 by operating the knob housing 230. In the illustrated embodiment, the knob housing 230 has a semi-enclosed configuration with the purpose of ensuring that the magnetic attraction with the regulator valve 300 is sufficiently large. In other embodiments, not shown, the knob housing 230 may also have a fully enclosed structure to enclose the first magnetic body 210 and the knob base 220 therein, in case that sufficient magnetic attraction force can be ensured, so that daily cleaning is more convenient.

In the case where the first magnetic body 210 is a magnetic member that can be attracted by the permanent magnet, the knob base 220 is not required, and the first magnetic body 210 may be directly connected to the knob housing 230. Illustratively, the first magnetic body 210 may be coupled to the bottom of the knob housing 230.

The regulator valve 300 includes a valve body 310, a valve stem 320, and an electromagnet 330. The valve stem 320 has a first end 321 and a second end 322 disposed opposite to each other. The first end 321 is connected to the valve body 310. Typically, the valve body 310 includes a valve housing (not shown) and a valve spool (not shown). The valve spool is rotatable within and relative to the valve housing to adjust the amount of venting through the valve body 310. In the embodiment that the stove is an electromagnetic stove, the amount of current led into the stove can be adjusted through the rotation of the valve core. The first end 321 of the valve stem 320 is actually connected to the valve spool, and the valve stem 320 rotates the valve spool within the valve housing. This is well known in the art and will not be described in detail here. The valve stem 320 as a whole is rotatable relative to the valve body 310.

The electromagnet 330 is a device that is energized to generate an electromagnet. After the power is turned on, the magnetic body can attract the first magnetic body 210 by magnetic force, and after the power is turned off, the magnetic force between the magnetic body and the first magnetic body 210 can disappear. Generally, an electromagnet comprises a core and an electrically conductive winding wound on the outside of the core to match the power of the core. The electromagnet 330 is coupled to the second end 322 of the valve stem 320 and rotates the valve stem 320 along the axis of the valve stem 320 to effect an adjustment of the regulator valve 300.

Illustratively, the regulator valve 300 may also include a valve seat 340. The electromagnet 330 may be disposed on a valve base 340, the valve base 340 being coupled to the second end 322 of the valve stem 320. The valve base 340 has a disk shape coaxially disposed with the valve stem 320. Thus, the electromagnet 330 is more convenient to mount, and meanwhile, the electromagnet 330 drives the valve rod 320 to rotate through the connection between the valve base 340 and the valve rod 320, so that the structure is more stable.

When a user desires to adjust the regulator valve 300, the electromagnet 330 is energized, causing the electromagnet 330 to generate a magnetic field. The user may now place the ignition knob 200 over the faceplate 100 with the electromagnet 330. The ignition knob 200 is attracted to the panel 100 by the first magnetic substance 210 in the ignition knob 200 being attracted by the electromagnet 330. Since the first magnetic body 210 in the ignition knob 200 corresponds to the electromagnet 330 in position and the first magnetic body 210 in the same position has opposite polarity to the electromagnet 330, when the ignition knob 200 is rotated by a user, the electromagnet 330 can rotate along with the ignition knob 200 by the magnetic attraction between the first magnetic body 210 and the electromagnet 330, so as to drive the valve stem 320 to rotate, thereby adjusting the ventilation amount of the adjusting valve 300.

A controller 400 is also included in the adjustment device. The controller 400 may be configured to control the electromagnet 330 to have at least a first magnetic field strength B₁And a second magnetic field strength B₂WhereinFirst magnetic field strength B₁Greater than the second magnetic field strength B₂. Second magnetic field strength B₂May be less than the first magnetic field strength B₁Including zero. For example, when the user is using the ignition knob 200, the controller 400 causes the electromagnet 330 to generate the first magnetic field strength B₁The ignition knob 200 is firmly attracted to the panel 100 by the electromagnet 330, so that the valve rod 320 can be driven to rotate by the electromagnet 330 when the ignition knob 200 is rotated, and the fire power of the cooker can be adjusted by the adjusting valve 300. When the user finishes using the cooker or cleans the cooker panel 100, the controller 400 controls the electromagnet to generate the second magnetic field strength B₂The electromagnet 330 is caused to generate a weak or no magnetic attraction force on the ignition knob 200. Thus, the user can conveniently remove the ignition knob 200.

Illustratively, in one embodiment, the second magnetic field strength B₂At this point, the electromagnet 330 has no attractive effect on the ignition knob 200. The ignition knob 200 can be easily removed. The user can clean the panel 100 or place the ignition knob 200 in a location that is not touched by children, improving safety. In another embodiment, the second magnetic field strength B₂May have a smaller value, the second magnetic field strength B₂The electromagnet 330 is limited to attracting the ignition knob 200, but the magnetic field is not sufficient to cause the electromagnet 330 to be carried by the ignition knob 200. That is, at this time, the ignition knob 200 is not easily separated from the panel 100, and the original fire power of the regulator valve 300 is not changed by the rotation thereof. At this time, it is suitable for the user to clean the panel 100, and the user can easily remove the ignition knob 200 from the panel 100. When the user has cleaned the panel 100, the ignition knob 200 is simply placed at its original position, and the second magnetic field B generated by the electromagnet 330₂The ignition knob 200 is attached to the panel 100. This prevents the ignition knob 200 from being lost when the user is not using the cooktop.

It can be seen that when the electromagnet 330 has the first magnetic field strength B₁In the meantime, the ignition knob 200 is firmly attracted to the electromagnet 330 below the panel 100Above the panel 100, the first magnetic body 210 can drive the electromagnet 330 of the regulating valve 300 to rotate, so as to drive the valve rod 320 to rotate relative to the valve body 310, thereby regulating the fire power of the stove. When the user stops using the cooker or cleans the cooker, the electromagnet 330 has a second magnetic field intensity B₂The ignition knob 200 can be easily taken away from the panel 100, and the user can clean the panel 100 and place the panel in a place where children cannot touch the panel, thereby improving safety.

In addition, when the second magnetic field intensity B₂When the time is not zero, the ignition knob 200 can be adsorbed on the panel 100 by the magnetic attraction of the electromagnet 330 to the ignition knob 200, and any action of the ignition knob will not cause the adjustment of the adjusting valve 300 to the fire of the cooker, so that the loss is prevented, and the use experience of a user is improved.

Illustratively, as shown in FIG. 1, the controller 400 is a power switch, i.e., the controller 400 controls the first magnetic field strength B generated by the electromagnet 330₁And a second magnetic field strength B₂Middle and second magnetic field strength B₂Is zero. Thus, there is no magnetic attraction between the ignition knob 200 and the regulator valve 300 when not in use or when cleaning. To prevent the loss, a second magnetic body 240 may be provided at the center of the bottom of the ignition knob 200, and a third magnetic body 350 may be provided at the center of the top of the regulator valve 300. Wherein at least one of the second and third

magnetic bodies

240 and 350 is a permanent magnet. Preferably, both are provided as permanent magnets. And the magnitude of the magnetic attractive force between the second magnetic body 240 and the third magnetic body 350 may have the following characteristics: under the condition that the electromagnet 330 does not generate a magnetic field, the ignition knob 200 is not separated from the panel 100 of the cooker, and the user can easily take down the ignition knob 200 when the user wants to take down the ignition knob. Thus, even if the electromagnet 330 does not generate a magnetic field, the ignition knob 200 is not easily separated from the panel 100, and the possibility that the ignition knob 200 is lost is reduced.

Illustratively, the controller 400 may further include a first controller 410 and a second controller 420. Wherein the first controller 410 may control the electromagnet 330 to have a first magnetic field strength B₁Or the firstTwo magnetic field intensity B₂The first controller 410 and the second controller 420 may be configured to collectively control the electromagnet 330 to have a third magnetic field strength B₃. Wherein the third magnetic field strength B₃Open at a first magnetic field strength B₁And a second magnetic field strength B₂In the meantime.

In one embodiment, as shown in fig. 3, the first controller 410 may be a single pole double throw switch having two contacts, a first contact 412 and a second contact 414. The first contact 412 is connected to the electromagnet and the second controller 420 is connected in series between the second contact 414 and the electromagnet 330. The electromagnet 330 may have a first magnetic field strength B when the first contact 412 is conductive₁(ii) a When the second contact 414 is conductive, the second magnetic field strength B of the electromagnet 330₂. Illustratively, the second controller 420 may be, for example, a sliding rheostat. In this case, the second controller 420 and the first controller 410 together control the electromagnet 330 to have the third magnetic field strength B₃。

The magnetic attraction of the third magnetic field strength B3 to the ignition knob 200 can not only prevent the ignition knob 200 from separating from the panel 100 of the cooker, but also allow the user to easily remove the ignition knob 200 when the user wants to remove the ignition knob. The switch of the controller 400 may also be turned off when the ignition knob 200 is not used for a long period of time. Thus, the ignition knob 200 is not easily separated from the panel 100 under the common control of the first controller 410 and the second controller 420, thereby reducing the possibility of the ignition knob 200 being lost.

Illustratively, the controller 400 may be a current regulator or a position regulator to adjust the magnitude of the current through the electromagnet 330 by the controller 400 or to adjust the magnetic field strength of the electromagnet 330 by changing the number of energized coils of the electromagnet 330. The different strengths of the magnetic fields generated by the electromagnet 330 are made such that the ignition knob 200 can be applied to products having different thicknesses of the panel 100, so that the ignition knob 200 can maintain its loss prevention function on various products. The design work of the product is reduced, and the cost of the product is reduced.

Illustratively, the ignition knob 200 includes at least one pair of first magnetic bodies 210, each pair of first magnetic bodies 210 being symmetrically disposed about a central axis of the ignition knob 200, and the regulating valve 300 also includes at least one pair of electromagnets 330, the electromagnets 330 being disposed in correspondence with the first magnetic bodies 210. By the arrangement, the ignition knob 200 is uniformly stressed when adjusting the adjusting valve 300, so that the adjusting valve 300 is rotated along with the ignition knob 200, the synchronism is higher, and the user can adjust the firepower more finely. Meanwhile, the first magnetic body 210 and the electromagnet 330 are at least provided with one pair, so that when the ignition knob 200 is adsorbed on the panel 100 by a user, the first magnetic body 210 is more easily corresponding to the electromagnet 330 below the panel 100, and the use experience of the user is improved.

Illustratively, all of the first magnetic bodies 210 on the ignition knob 200 have the same polarity direction. Referring back to fig. 1, when the N poles of all the first magnetic bodies 210 are directed upward, the N poles of the electromagnets 330 are also directed upward. Therefore, on one hand, for the mounting process, the winding manner of the coil on each electromagnet 330 is the same, and the mounting directions of the first magnetic bodies 210 are uniform, thereby reducing the probability of error generation and improving the product quality. On the other hand, when the user attaches the ignition knob 200 to the panel 100, the first magnetic member 210 and the electromagnet 330 may generate an attractive force, and the user does not need to rotate the ignition knob 200 according to the direction of the magnetic pole to find a corresponding angle. The adsorption efficiency is improved, and the use experience is improved.

Illustratively, as shown in fig. 4, the adjusting device further includes a display device 500 for displaying the operation state of the electromagnet 330. The user can adjust the magnitude of the current of the electromagnet 330 (including turning the current on and off) by operating the controller 400. For example, the display device 500 may be an indicator light, in which case the controller 400 may reflect the magnitude of the magnetic force generated by the electromagnet 330 by controlling the brightness, color, and number of the indicator lights of the display device 500. The display device 500 may also be a display screen, for example. Through the display device 500, the user can clearly understand the operation of the electromagnet 330 without sensing the operation of the electromagnet 330 through the magnetic attraction force to the ignition knob 200.

For example, as shown in FIG. 2, an angle sensor 600 may be provided on the valve stem 320 of the regulator valve 300. In this case, as shown in fig. 4, the display device 500 may also be used to display the amount of the fire of the cooker. The angle sensor 600 detects the rotation angle of the valve stem 320, and the controller 400 may control the display device 500 to display the corresponding amount of fire according to the detection result of the angle sensor 600.

For example, the rotatable angle of the valve stem 320 relative to the valve body 310 may be between 0 degrees and 180 degrees, and the display device 500 may include a plurality of indicator lights. The firepower of the cooker is reflected by the number of the lighted indicator lamps. Thus, even if the ignition knob 200 is not provided with scales, the user can clearly know the current firepower of the cooker. Through the display cooking utensils firepower of display device 500, improved the precision that the user controlled the firepower, also improved user's use simultaneously and experienced.

According to another aspect of the utility model, still provide a cooking utensils. The cooker comprises a panel 100 and any one of the above adjusting devices. The stove can also be a gas stove such as a natural gas stove, an artificial gas stove or a liquefied petroleum gas stove, or an electromagnetic stove.
