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.

Generally, an adjusting device 100 is provided on a cooking range, as shown in fig. 1, for adjusting the fire power of the cooking range. The utility model provides an adjusting device 100 for cooking utensils, including the governing valve 120 that is located the ignition knob 110 on the panel 200 of cooking utensils and is located the panel 200 below. The ignition knob 110 and the adjusting valve 120 are provided with adjusting magnetic members 130. The adjusting magnetic member 130 of the ignition knob 110 may be provided at the outer peripheral portions of the ignition knob 110 and the adjusting valve 120. Generally, the adjusting magnetic member 130 is disposed at the outer edge of the bottom of the ignition knob 110, and is disposed opposite to the adjusting magnetic member 130 of the adjusting valve 120, so that the adjusting magnetic member 130 has a large distance from the axis, and thus, a large moment is generated during the rotation, which is more advantageous for controlling the adjusting device 100.

The adjusting magnets 130 on the ignition knob 110 and the adjusting valve 120 may both be permanent magnets or both be electromagnets. Alternatively, the adjusting magnetic member 130 of one of the ignition knob 110 and the adjusting valve 120 is a permanent magnet or an electromagnet, and the adjusting magnetic member 130 of the other is made of a ferrous material.

Illustratively, the regulator valve 120 may include a valve housing 121, a valve spool, and a valve stem 122. The valve stem 122 extends along a central axis of the ignition knob 110, and a first end 1221 of the valve stem 122 is connected to the valve cartridge. The valve core is disposed in the valve housing 121, and the valve stem 122 can rotate the valve core relative to the valve housing, thereby adjusting the ventilation of the regulating valve 120. The above-described structure of the regulator valve 120 is well known in the art, as it will not be described in further detail herein. The regulating magnetic 130 of the regulating valve 120 may be disposed at the second end 1222 of the valve stem 122. Illustratively, the adjusting magnetic member 130 may be secured to the second end 1222 of the valve stem 122 by the valve stem base 123.

Through the magnetic attraction between the ignition knob 110 and the adjusting magnetic member 130 on the adjusting valve 120, the ignition knob 110 not only can drive the valve stem 122 to rotate, but also can be held on the panel 200 of the cooker. When the user uses the cooker, the user can manually operate the ignition knob 110 to adjust the fire power of the adjusting valve 120 under the cooker panel 200. When the user does not use or needs to clean the cooktop panel 200, the user can remove the ignition knob 110 from the panel 200 to clean the panel 200. The adjusting device 100 may be used for a gas range. The adjusting device 100 can also be used for induction cookers, if possible. The structure of the adjusting device 100 for adjusting the fire of the cooking range is well known in the art, and the improvement point of the present invention is not described here, so the structure of the part will not be described in detail.

Generally, the valve stem 122 with the valve core can only rotate within a certain angle range during the adjustment of the ventilation amount of the adjusting valve 120 below the panel 200. Within this range of rotational angles, the valve stem 122 may rotate synchronously with the ignition knob 110 above the faceplate 200. However, when the valve stem 122 has been rotated to the extreme position following the ignition knob 110, and the user continues to rotate the ignition knob 110, the ignition knob 110 is prone to magnetic cross-displacement, which may cause the ignition knob 110 to deflect. The so-called magnetic cross-cutting dislocation phenomenon means that after the valve stem 122 below the panel 200 stops rotating along with the ignition knob 110, the user continues to rotate the ignition knob 110, which drives the ignition knob 110 to deviate from the original axial position, and finally loses the control function on the adjusting valve 120, even falls off from the panel 200 of the kitchen range.

To solve the above problem, an adjusting device 100 according to an embodiment of the present invention is shown in fig. 1. In addition to the ignition knob 110 and the regulator valve 120, a stationary base 140 is included. The fixing base 140 may be fixed on the panel 200.

Illustratively, the fixing base 140 may be adhered to the panel 200 at the bottom. That is, an adhesive layer is provided between the fixing base 140 and the panel 200. The fixing base 140 is fixed to the rice 200 by an adhesive layer. The method is simple and easy to implement and low in cost.

In another embodiment, the fixing base 140 may be attached to a panel made of metal by disposing a magnetic member on the fixing base 140, or the fixing base 140 may be firmly attached to the panel 200 by disposing a magnetic member under the panel. The fixed base 140 will be fixed and immovable with respect to the faceplate 200 anyway. One embodiment of the fixing manner of the fixing base 140 will be described in detail below.

The ignition knob 110 may be attached to a fixed base 140 fixed to the panel 200, the ignition knob 110 being limited in freedom in the horizontal plane, but rotatable relative to the fixed base 140.

Illustratively, one of the fixing base 140 and the firing knob 110 has a shaft, and the other has a shaft hole. The shaft is rotatably received within the shaft bore and the axis of the shaft coincides with the axis of the ignition knob 110. Thus, the ignition knob 110 is rotatable about the central axis of the ignition knob 110 relative to the stationary base 140 by the mating of the shaft and the shaft bore. The shaft may have various shapes such as a cylinder, a circular truncated cone, a semi-sphere, etc., as long as it can be fitted with the shaft hole so that the shaft can be rotated with respect to the shaft hole. In fig. 1, a shaft is provided on the fixing base 140, and a shaft hole is provided on the ignition knob 110.

In the case of a connection via a shaft and a shaft bore, the ignition knob 110 can be positioned only in the horizontal direction, in the axial direction, the ignition knob 110 can be held in its position by means of the adjusting magnetic element 130. Such a connection structure of the ignition knob 110 and the fixing base 140 is simple, convenient to connect, and easy to process. Further, since the fixing base 140 does not restrict the degree of freedom of the ignition knob 110 in the axial direction, the user can easily remove the ignition knob 110 from the panel 200.

Optionally, to prevent loss of the ignition knob 110, the ignition knob 110 may also be restrained from the stationary base 140 in the axial direction. For example, a connector or snap fit arrangement may be used to connect the ignition knob 110 to the stationary base 140. Illustratively, magnetic members may be further provided on the ignition knob 110 and the fixed base 140 to connect the ignition knob 110 and the fixed base 140 by magnetic attraction. The above restrictions on the degree of freedom in the axial direction do not prevent the ignition knob 110 from being rotatable about the fixed base 140.

The utility model discloses need not to restrict the connected mode between ignition knob 110 and fixed baseplate 140, as long as can realize ignition knob 110 around the rotatable purpose of its central axis can.

Within the rotatable angle range of the adjusting valve 120, the adjusting valve 120 will rotate along with the ignition knob 110 above the panel 200 to adjust the fire power of the stove. When the adjusting valve 120 has been rotated to the limit position, if the fixing base 140 is not provided, if the ignition knob 110 is rotated continuously, the rotation force of the ignition knob 110 by hand and the magnetic attraction between the adjusting magnetic members 130 are simultaneously applied, so that the magnetic force is crossed and dislocated, that is, the ignition knob 110 is thrown outward along the force application direction by taking one pair of the adjusting magnetic members 130 as the axis, and the ignition knob 110 is laterally deviated or even separated from the panel 200. But due to the limited freedom of the ignition knob 110 in the horizontal plane by the fixed base 140, a laterally offset force will act on the fixed base 140. Since the stationary base 140 is firmly fixed to the cooktop panel 200 in the manner described above, the ignition knob 110 is not deviated from the original rotation axis by the lateral offset force.

Thus, by providing the fixing base 140, when the user rotates the ignition knob 110 beyond the rotation range of the adjustment valve 120, the phenomenon that the ignition knob 110 deviates from the original axial position due to the lateral deviation, loses the control function of the adjustment valve 120, and even falls off from the cooker panel 200 can be avoided. The safety of cooking utensils use has been improved, user's use experience has also been improved.

Illustratively, the top center of the regulator valve 120 has a first central magnetic member 150, the fixed base 140 has a second central magnetic member 160, the polarities of the first and second central

magnetic members

150 and 160 are opposite, and the fixed base 140 is fixed to the faceplate 200 by the first and second central

magnetic members

150 and 160.

The second central magnetic member 160 can fix the fixed base 140 on the panel 200 through the magnetic attraction with the first central magnetic member 150 at the top center of the adjusting valve 120, and since the adjusting valve 120 below the panel 200 is fixed relative to the panel 200 at the planar position, under the influence of the magnetic attraction, the second central magnetic member 160, i.e., the fixed base 140, will also be fixed relative to the panel 200 and located on the axis of the adjusting valve 120, and even if the adjusting valve 120 rotates along the axis, the fixed base 140 can be kept at the original position.

Like this, fix unable adjustment base 140 on panel 200 through magnetic attraction, can avoid being connected unable adjustment base 140 and panel 200 through other modes such as pasting, reduced technology, but also improved the wholeness of panel, the user can also take off unable adjustment base 140 from panel 200 at any time when clean panel 200, has improved and has used experience.

When the fixing base 140 is fixed using the first and second central

magnetic members

150 and 160, it is required that the first and second central

magnetic members

150 and 160 can generate a sufficiently large magnetic attraction force. Therefore, the volume and cost of the first and second central

magnetic members

150 and 160 may increase. In consideration of these factors, in the case where the first and second central

magnetic members

150 and 160 are present, an adhesive layer may also be provided between the fixing base 140 and the panel 200, that is, the fixing base 140 is fixed to the panel 200 by magnetic attraction and adhesion.

For example, as shown in fig. 1, the fixed base 140 may have a disc shape, which may increase a contact area between the fixed base 140 and the panel 200, and reduce a pressure of the panel 200 due to a magnetic attraction force generated between the first central magnetic element 150 and the second central magnetic element 160, thereby protecting an outer surface of the panel 200. The second central magnetic member 160 is cylindrical and is located at the top center of the fixed base 140. Thus, the second central magnetic member 160 can be used as a rotation shaft of the ignition knob 110 while fixing the fixing base 140 to the panel 200, and has a simple structure and is easy to process.

Fig. 2 provides another embodiment adjustment device 100'. As shown, the fixed base 140' may include only the second central magnetic element. Thus, the structure is simpler. Components in the embodiment shown in fig. 2 that are identical to components in fig. 1 have been given the same reference numerals and will not be described in further detail here.

Illustratively, the bottom of the ignition knob 110 is provided with a cylindrical recess into which the second central magnetic member is inserted.

Thus, the ignition knob 110 is simple in construction, easy to manufacture, and easy to install.

The valve stem 122 may have a first end 1221 and a second end 1222 disposed opposite one another. Illustratively, the second end 1222 may be coupled to the valve stem base 123, the first central magnetic element 150 is disposed at the center of the valve stem base 123, and the adjusting magnetic element 130 is disposed on the valve stem base 123 and around the first central magnetic element 150.

When a user rotates and adjusts the ignition knob 110, the ignition knob 110 rotates around the fixed base 140, the adjusting magnetic member 130 on the ignition knob 110 attracts the adjusting magnetic member 130 arranged on the valve stem base 123 under the panel 200, and drives the valve stem base 123 and the valve stem 122 to rotate, so as to rotate the valve element in the valve housing 121, thereby achieving the purpose of controlling the amount of fire.

In this way, by disposing both the first central magnetic member 150 and the adjusting magnetic member 130 on the fixed base 140, the structure of the adjusting valve 120 can be simplified, and the structure thus disposed is compact and the manufacturing process is simple.

Illustratively, the number of the adjusting magnetic members 130 on the valve stem base 123 and the number of the adjusting magnetic members 130 on the ignition knob 110 are both even, the polarity of any two adjacent adjusting magnetic members 130 on the valve stem base 123 is opposite, and the polarity of any two adjacent adjusting magnetic members 130 on the ignition knob 110 is opposite. Thus, when the adjusting valve 120 has been rotated to the extreme position and the user continues to rotate the ignition knob 110, the ignition knob 110 will be rotated to the angle where the polarities of the adjusting magnetic members 130 above and below the faceplate 200 are the same, since the polarities of the adjacent two adjusting magnetic members 130 are opposite. The adjusting magnetic member 130 on the ignition knob 110 at this time will receive repulsive force from the adjusting magnetic member 130 on the adjusting valve 120 under the panel. In embodiments where the ignition knob 110 is not secured to the stationary base 140 in the axial direction, the ignition knob 110 will be pushed away from the faceplate 200 by the repelling force. But is restrained by the fixed base 140 so that the ignition knob 110 does not shift horizontally. This state is unstable, and after the ignition knob 110 is further rotated, the ignition knob 110 is rotated to an angle for adjusting the opposite polarities of the magnetic members 130 above and below the panel 200. The ignition knob 110 will be attracted to the panel 200 again by the magnetic attraction. Because the ignition knob 110 and the panel are mostly made of metal and glass, the two devices collide with each other and will give out impact sound. In this way, the user may be alerted that the regulator valve 120 has been rotated to maximum or minimum fire.

It can be seen that this arrangement allows the user to push the ignition knob 110 away from the panel after the user has turned the ignition knob 110 to the extreme position and, upon again contacting the panel, sounds a sound to indicate to the user that the adjustment valve 120 has reached the extreme position. The safety in utilization of cooking utensils is improved, user's use experience has also been improved simultaneously.

In another embodiment, the means for emitting the impact sound may also be a valve body, in particular, retractable in the direction of extension of the valve stem. Illustratively, as shown in FIG. 3, in the adjustment device 100 ", the valve stem 122" may include an upper portion and a lower portion that are telescoped together, and the upper portion may be inserted into the lower portion. A compression spring may be sleeved on the upper portion within the lower portion, thereby enabling the valve stem 122 "to telescope in its direction of extension. In another embodiment, as shown in fig. 4, in the adjustment device 100 "', a bore is provided in the valve housing 121"' that receives the first end 1211 of the valve stem 122 "', the first end 1211 of the valve stem 122"' is attached within the bore, and a compression spring 124 is fitted over the first end 1211. The valve stem 122 "'is movable axially within the valve housing 121"' and is returned to its initial position by a compression spring 124. Illustratively, the initial position of the stem 122' ″ is a position where the adjustment magnetic member 130 or the first central magnetic member 150 abuts against the lower surface of the faceplate 200.

Thus, when the adjusting valves 120 "and 120'" have been rotated to the extreme positions and the user continues to rotate the ignition knob 110, the ignition knob 110 will be rotated to the angle where the adjusting magnetic members 130 above and below the faceplate 200 have the same polarity because the polarities of the adjacent two adjusting magnetic members 130 are opposite. The adjusting magnetic member 130 on the ignition knob 110 and the adjusting magnetic member 130 on the valve stem base 123 will be subjected to the repulsive force generated by the same poles at this time, so that the valve stem 122 is compressed and the second end 1212 of the valve stem 122 is moved downward. After the user continues to rotate the ignition knob 110, the ignition knob 110 is rotated to the angle of the opposite polarity of the adjustment magnetic members 130 above and below the faceplate 200. Under the action of the spring, the valve stem 122 returns to the original extended state, thereby emitting an impact sound to alert the user that the valves 120 "and 120'" have been rotated to maximum or minimum fire.

It will be appreciated that this arrangement allows the valve stem base 123 to be pushed away from the faceplate after the user has turned the ignition knob 110 to the extreme position, and when again contacting the faceplate, sounds to indicate to the user that the adjustment valves 120 "and 120'" have reached the extreme position. The safety in utilization of cooking utensils is improved, user's use experience has also been improved simultaneously.

Components in the embodiment shown in fig. 3-4 that are identical to components in fig. 1 have been given the same reference numerals and will not be described in further detail herein. Furthermore, it will be appreciated that the embodiment shown in FIGS. 3-4 may be combined with the embodiment shown in FIGS. 1-2, i.e., the impact sound emitted by both the regulator valves 120 "and 120 '" and the firing knob 110 simultaneously alerts the user of the extreme positions of the regulator valves 120 "and 120'".
