Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A cooking appliance 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.
As shown in fig. 1 to 6, the cooking appliance 1 according to the embodiment of the present invention includes an inner pot 10 and a coil panel assembly 20, and particularly, the cooking appliance 1 may be a pressure cooker.
A coil disk assembly 20 according to an embodiment of the present invention is described first with reference to the drawings.
As shown in fig. 1 to 6, a coil disk assembly 20 according to an embodiment of the present invention includes a coil disk holder 100, a coil disk 200, an elastic member 300, and a temperature-sensitive repositioner 400.
The coil disk 200 is movably mounted on the coil disk holder 100 between a heatable position and a heating-off position. Both ends of the elastic member 300 are connected to the coil disk holder 100 and the coil disk 200, respectively. The temperature-sensitive repositor 400 is mounted on at least one of the coil disk holder 100 and the coil disk 200.
When the temperature sensed by the temperature-sensitive repositor 400 is less than the predetermined temperature, the coil panel 200 is maintained at the heatable position by the elastic force of the elastic member 300. When the temperature sensed by the temperature-sensing repositor 400 is greater than or equal to the predetermined value, the coil panel 200 moves to the heating stop position against the elastic force of the elastic element 300 under the action of the temperature-sensing repositor 400.
The coil base 100 is used as a pressure-bearing member to support the inner pot of the pressure cooker, the coil panel 200 is movably matched with the coil base 100, in the working process, as the temperature inside the pressure cooker rises continuously, the coil panel 200 is influenced by the temperature inside the pressure cooker, the temperature of the coil panel 200 rises continuously, when the temperature of the coil panel 200 is high to the preset value, the temperature-sensing restorer 400 starts to act to push the coil panel 200 to move to the heating stop position in the direction away from the coil base 100 (namely away from the inner pot), at the heating stop position, the distance between the coil panel 200 and the inner pot is relatively larger, at the moment, the inner pot is positioned outside the magnetic field generated by the coil panel 200, the coil panel 200 does not heat the inner pot any more, after the temperature of the coil panel 200 is reduced to be lower than the preset value after the heating is stopped for a period of time, the temperature-sensing restorer 400 starts to restore, at the moment, the elastic member 300 pushes the coil panel 200 to move, at this time, the inner pot is returned to the magnetic field of the coil panel 200, the coil panel 200 heats the inner pot again, and the above-described operation is repeated during the continuous operation to heat the inner pot.
In the present invention, the temperature-sensing restorer 400 is engaged with the coil panel 200 in a heat-transferable manner, and since the temperature-sensing restorer 400 can operate to push the coil panel 200 open when the temperature of the temperature-sensing restorer 400 reaches the predetermined value, the preset value set by the temperature-sensing restorer 400 is the upper temperature limit of the coil panel 200, or the upper temperature limit of the coil panel 200 is lower than the preset value of the temperature-sensing restorer 400 in consideration of the heat loss of the heat transfer between the temperature-sensing restorer 400 and the coil panel 200, in short, the temperature of the coil panel 200 itself does not exceed the preset value when the coil panel operates with the above-described structure. Therefore, the invention can effectively avoid the temperature of the coil panel 200 from continuously rising when the pressure cooker works, can control the temperature of the coil panel 200 in time, and avoids the influence of overhigh temperature on the coil panel 200 and peripheral electronic components thereof.
The invention directly realizes the control of the temperature of the coil panel 200 through the elastic element 300 and the temperature sensing restorer 400, does not need to arrange a sensor for detecting the temperature of the coil panel 200 on the coil panel 200, simultaneously realizes the temperature control in a mechanical mode and has higher reliability.
In the cooking appliance 1 according to the embodiment of the present invention, the controller communicates with the coil disk 200. The coil disk 200 is adjacent to the inner pot 10 in the heatable position, and the controller controls the coil disk 200 to heat so that the inner pot 10 heats the food therein. When the coil panel 200 is away from the inner pot 10 at the heating stop position, the cooking appliance 1 is in a "no pot state", and the controller controls the coil panel 200 to stop heating.
As will be understood by those skilled in the art, in the determination of the "no pot state", when the distance between the coil panel 200 and the inner pot 10 changes, both the current and the resistance of the coil panel 200 change, that is, when the coil panel 200 moves to the heating stop position and is away from the inner pot 10, the distance between the two changes, and the current and the resistance of the coil panel 200 change, and by detecting the change of the current or the resistance, it is possible to determine whether the coil panel 200 is in the heating stop position, thereby determining whether the coil panel is in the "no pot state".
The coil disk assembly 20 according to the embodiment of the present invention is configured such that, by movably mounting the coil disk 200 on the coil disk holder 100, and the elastic member 300 and the temperature-sensitive reset device 400 are provided, so that when the temperature of the coil disk 200 reaches a predetermined temperature, the coil panel 200 moves to the heating stop position against the elastic force of the elastic member 300 under the action of the temperature-sensing repositor 400, the coil panel 200 is far away from the inner pot 10 and stops heating for heat dissipation, since the inner pot 10 has a certain temperature, the distance between the coil panel 200 and the inner pot 10 is increased, the heat dissipation space of the coil panel 200 can be increased to facilitate the heat dissipation of the coil panel 200, thereby improving the heat dissipation efficiency of the coil panel 200, recovering to a heatable position under the elastic force of the elastic member 300 when the coil panel 200 dissipates heat and cools to a temperature less than a predetermined temperature, since the heat dissipation time of the coil disk 200 is greatly shortened, the sustainable heating time of the coil disk 200 is prolonged.
Therefore, the coil panel assembly 20 according to the embodiment of the invention has the advantages of good heat dissipation effect, long sustainable heating time and the like.
According to the cooking appliance 1 of the embodiment of the invention, by using the coil panel assembly 20 of the above-mentioned embodiment of the invention, the advantages of good heat dissipation effect, long sustainable heating time and the like are achieved.
A coil disk assembly 20 according to an embodiment of the present invention is described below with reference to the drawings.
As shown in fig. 1 to 6, a coil disk assembly 20 according to an embodiment of the present invention includes a coil disk holder 100, a coil disk 200, an elastic member 300, and a temperature-sensitive reset 400.
Specifically, as shown in fig. 1 to 6, the coil disk 200 is mounted on the coil bobbin 100 to be movable up and down and located below the coil bobbin 100, the coil disk 200 is adjacent to the coil bobbin 100 in the heatable position, and the coil disk 200 is distant from the coil bobbin 100 in the stop heating position. Thereby, the supporting effect of the coil disk holder 100 and the protecting effect of the coil disk 200 can be improved.
In some embodiments of the present invention, as shown in fig. 1 to 6, in order to facilitate the movable mounting of the coil disk 200 on the coil disk holder 100, a guide 500 is mounted on a lower portion of the coil disk holder 100, and the coil disk 200 is movably mounted on the guide 500 between the heatable position and the heating stop position, and can guide the movement of the coil disk 200, thereby improving the stability of the movement of the coil disk 200.
Specifically, as shown in fig. 1 and 4, the guide 500 includes a threaded section 510, a guide section 520, and a stop cap 530.
The threaded section 510, the guiding section 520 and the limiting cap 530 are connected in sequence, that is, two ends of the guiding section 520 are respectively connected with the threaded section 510 and the limiting cap 530. The coil disk base 100 is provided with a threaded hole in which the threaded section 510 is fitted. The coil panel 200 is provided with a guide through hole movably matched with the guide section 520, that is, the guide section 520 passes through the guide through hole. The coil disk 200 is stopped by one of the coil holder 100 and the retaining cap 530 in the heatable position, and the coil disk 200 is stopped by the other of the coil holder 100 and the retaining cap 530 in the stop heating position. For example, the coil disk 200 is stopped by the coil disk holder 100 in the heatable position, and the coil disk 200 is stopped by the stopper cap 530 in the stop heating position. Therefore, the coil panel 200 can be movably mounted on the coil panel base 100, and the coil panel 200 at two limit positions can be limited to prevent the coil panel 200 from falling off.
Optionally, the elastic element 300 is a spring sleeved on the guiding section 520 and two ends of the spring respectively abut against the coil panel 200 and the limiting cap 530, so as to implement the installation and positioning of the elastic element 300, the elastic element 300 may be in a compressed state, and when the temperature sensed by the temperature-sensing repositor 400 is less than a predetermined temperature, the elastic element 300 pushes the coil panel 200 upward to the heatable position.
Advantageously, as shown in fig. 1 and 4, the coil base 100 is provided with a mounting leg 110, and the threaded hole is provided in the mounting leg 110. The diameter of the guiding section 520 is greater than the maximum diameter of the threaded section 510, the maximum diameter of the limiting cap 530 is greater than the diameter of the guiding section 520, the minimum outer diameter of the mounting leg 110 is greater than the diameter of the guiding section 520, and the diameter of the guiding through hole is slightly greater than the diameter of the guiding section 520 and smaller than the maximum diameter of the threaded section 510, so that the limiting cap 530 and the mounting leg 110 are enabled to stop and limit the coil disc 200 at two limit positions.
In order to save space, the cross-sectional area of the guide section 520 is gradually reduced in a direction away from the guide section 520 (e.g., from top to bottom), and preferably, the stopper cap 530 has a segment shape.
In some specific examples of the present invention, the guide members 500 are plural and are disposed at equal intervals in the circumferential direction of the coil disk 200, and the coil disk 200 is mounted on the coil disk holder 100 by the plural guide members 500 to improve stability of the coil disk 200 and smoothness during movement.
In some embodiments of the present invention, as shown in fig. 1-3, the temperature-sensitive repositor 400 is a temperature-sensitive metal sheet and includes a base plate 410 and a deformable limb 420,
the substrate 410 is mounted on one of the coil disk holder 100 and the coil disk 200. The deformation limb 420 is attached to the base plate 410 and may be integrally formed with the base plate 410. When the temperature sensed by the temperature-sensitive repositor 400 is greater than or equal to the predetermined value, the deformation limb 420 deforms and acts on the other one of the coil panel seat 100 and the coil panel 200, and the coil panel 200 moves to the heating stop position against the elastic force of the elastic member 300 under the pushing of the deformation limb 420. When the temperature sensed by the temperature-sensitive repositor 400 is lower than the predetermined temperature, the deformation limb 420 recovers its deformation, and the coil panel 200 recovers to the heatable position under the elastic force of the elastic member 300.
For example, when the substrate 410 is mounted on the coil panel 200 and the temperature sensed by the temperature-sensing repositor 400 is greater than or equal to the predetermined value (as shown in fig. 3), the deformation limb 420 is deformed to tilt upwards to abut against the coil panel base 100, so as to push the coil panel 200 to move downwards to the heating stop position against the elastic force of the elastic element 300. When the temperature sensed by the temperature-sensitive repositor 400 is lower than the predetermined temperature (as shown in fig. 2), the deformable limb 420 is deformed and close to the substrate 410, and at this time, the deformable limb 420 no longer contacts the coil base 100, and the coil panel 200 is restored to the heatable position under the elastic force of the elastic member 300.
Optionally, the temperature-sensing metal sheet (i.e., the temperature-sensing repositioner 400) is a ring-shaped member extending along the circumferential direction of the coil disk 200, or the temperature-sensing metal sheets (i.e., the temperature-sensing repositioner 400) are plural and are arranged at equal intervals along the circumferential direction of the coil disk 200, so that the stability of the coil disk 200 during movement can be improved.
Advantageously, as shown in fig. 1, in order to facilitate the installation of the temperature-sensitive repositioner 400, the coil disk 200 is provided with a substrate installation groove in which the substrate 410 is installed.
In some embodiments of the present invention, as shown in fig. 4-6, the temperature-sensing restorer 400 is a temperature-sensing magnetic element and includes a first temperature-sensing magnetic element 430 and a second temperature-sensing magnetic element 440.
The first temperature-sensing magnetic member 430 is mounted on the coil bobbin 100, and the second temperature-sensing magnetic member 440 is mounted on the coil bobbin 200. When the temperature sensed by the temperature-sensing repositor 400 is greater than or equal to the predetermined value (as shown in fig. 6), an interactive magnetic force is generated between the first temperature-sensing magnetic element 430 and the second temperature-sensing magnetic element 440 (the magnetic force shown in the figure is a repulsive force, although a suction force may be applied by changing the positions of the components), and the coil panel 200 moves down to the heating stop position by overcoming the elastic force of the elastic element 300 under the pushing of the magnetic force. When the temperature sensed by the temperature-sensing repositor 400 is lower than the predetermined temperature (as shown in fig. 5), the magnetic force of the interaction between the first temperature-sensing magnetic element 430 and the second temperature-sensing magnetic element 440 disappears, and the coil panel 200 moves up to the heatable position under the elastic force of the elastic element 300.
Optionally, the temperature-sensing magnetic element (i.e., the temperature-sensing repositioner 400) is a ring-shaped element extending along the circumferential direction of the coil disk 200, or the temperature-sensing magnetic elements (i.e., the temperature-sensing repositioner 400) are plural and are arranged at equal intervals along the circumferential direction of the coil disk 200, so that the stability of the coil disk 200 during movement can be improved.
Advantageously, as shown in fig. 4, in order to facilitate the installation of the temperature-sensitive repositioner 400, a first magnetic member installation groove is provided on the coil base 100 and the first temperature-sensitive magnetic member 430 is installed in the first magnetic member installation groove, and a second magnetic member installation groove is provided on the coil bobbin 200 and the second temperature-sensitive magnetic member 440 is installed in the second magnetic member installation groove.
