Description

  The present invention relates to an induction heating cooker.

The induction heating cooker performs cooking using the Joule heat generated by the eddy current generated at the bottom of the pan when the magnetic field lines generated by flowing a high-frequency current through the induction heating coil pass through the metal pan.
When heating such an induction heating cooker, not only the pot but also the induction heating coil and the electronic components on the control board that controls the induction heating coil generate heat, so the cooling air is blown from the blower and the induction heating coil and the control board are heated. Is cooling. For this reason, generally, the inlet for taking in air to an air blower is provided in the outline of a cooking appliance.

  This intake port is provided in various places by induction heating cooker, but depending on the position of the intake port, dust is sucked in and the intake port is blocked, resulting in deterioration of cooling performance and damage to internal parts. There is a fear. For this reason, some conventional induction heating cookers have a dustproof filter, and others have a mechanism for removing dust accumulated at the air inlet.

  There exists patent document 1 as an example of the induction heating cooking appliance which has a dustproof filter. As shown in FIG. 1 of this Patent Document 1, an intake port 13 composed of a plurality of small holes that do not allow a finger to enter the lower surface of the main body 12 is provided, and the intake port 13 is provided outside the intake port 13. This is an induction heating cooker in which a dustproof filter 17 provided with a plurality of small holes having a small diameter is detachably provided.

  There exists patent document 2 as an example of the induction heating cooking appliance which has a mechanism which removes the dust deposited on the inlet port. In this patent document 2, as described in FIG. 5 or FIG. 6 of the same document, the gap 21 between the opening-and-closing operation unit 18 and the operation unit case 20 provided on the front surface of the main body is used as an intake port, thereby The induction heating cooker has a function of dropping dust attached to the gap 21 when the portion 18 is opened and closed, and a function of scraping dust deposited and accumulated on the gap 21 by the convex portion 22.

In addition, a display operation unit 5 is arranged on the front side of the top plate 1 so that the heating power of the induction heating unit can be operated and the output state of the induction heating unit is displayed on a liquid crystal to give the user the strength of the heating output. introduce. A power switch 19 is attached to the upper part of the front operation unit 3.
In addition, although the arrow shown in FIG. 1 is a flow of cooling air, details are demonstrated in FIG.

  FIG. 2 is an exploded perspective view of the induction heating cooker described with reference to FIG. 1, in which the top plate 1 and the front operation unit 3 are removed from the main body, and the inverter board and the induction heating coil are mounted.

  FIG. 3 is an internal cross-sectional view of the induction heating cooker shown in FIG. 2 cut at substantially the center of the induction heating coil 6 on the right side when viewed from the front, and arrows in the figure indicate the flow of cooling air. Note that FIG. 3 partially shows the shape of the first embodiment for explanation, and a part of the configuration is omitted for explanation in FIGS. 2 and 3.

  2 and 3, below the top plate 1, an induction heating coil 6 corresponding to the right induction heating unit, an induction heating coil 7 corresponding to the left induction heating unit, and an induction corresponding to the central rear heating unit are shown. A heating coil 8 is attached. By applying a high frequency current to these induction heating coils 6, 7, 8, lines of magnetic force are generated, and the pot as a load is heated. Below the induction heating coil 6 on the right side, an inverter board 9 for controlling the induction heating coils 7 and 8 and a fan device 10 for supplying cooling air to the inverter board 9 and the induction heating coils 7 and 8 are housed. A substrate case 11 is disposed.

  The front operation unit 3 is housed in an operation unit case 20, and a clearance provided between the bottom side of the operation unit case 20 and the bottom side of the main body 2 serves as an intake port 16. An intake duct 18 for connecting the intake port 16 and the fan device suction port is provided between the lower surface of the case 11 and the main body 2, and the cooling air sucked from the intake port 16 passes through the intake duct 18 as shown in FIG. As shown by the arrow in FIG. Although the details will be described later, a dust filter 21 is attached to the intake port 16.

A fan device 10 including a fan 12 (turbo fan) is provided at the back of the substrate case 11, and the fan 12 is driven by a motor 13 to blow cooling air. As shown in FIG. 3, the fan device 10 sucks air from the fan device air inlet 14 and exhausts air from a plurality of discharge ports 15. In this embodiment, an example in which two discharge ports 15 are provided is shown, but three or more openings may be provided in accordance with the number of electronic substrates and induction heating coils and the amount of heat generated.
In this embodiment, the fan 12 is described as an example of a turbo fan having a fan inner diameter / fan outer diameter of 0.4 to 0.7, a blade outlet angle of 110 degrees or less, and the number of blades of 15 or less. However, an axial fan, a multiblade fan, or the like may be used, and the position of the fan may be arranged at a position other than the present embodiment.

Next, the flow of cooling air in the present embodiment will be described.
As shown in FIG. 3, the air inlet 16 provided between the operation unit case 20 in which the front operation unit 3 is housed and the bottom surface of the main body 2 serves as an inlet for cooling air inside the main body 2.
Although the intake port 16 is provided below the front operation unit 3 on the front surface of the main body 2 here, it may be provided on the back surface or the side surface of the main body 2.

  The cooling air drawn from the intake port 16 is guided to the fan device intake port 14 through the intake duct 18. The air taken in from the fan device suction port 14 is deflected by 90 degrees in the fan 12 by the rotation of the fan 12 driven by the fan motor 13, and then further deflected by 90 degrees in the fan device 10. And discharged from the discharge port 15. The inverter board 9 corresponding to each induction heating coil is stacked and arranged on the downstream side of the fan device 10, and the cooling air blown from the fan device 10, as shown by the arrows in FIG. Cool each induction heating coil. The cooling air that has cooled the inverter board 9 and each induction heating coil passes through the exhaust port 17 provided on the upper surface of the rear portion of the main body 2 and is discharged to the outside. As shown in FIG. 2, in this embodiment, there are two opening holes of the exhaust port 17.

In the above structure, the whole operation | movement in the case of cooking by putting a pan on the induction heating part of the right side is demonstrated easily.
First, a pan (not shown) is placed on the top plate 1 above the right induction heating coil 6, the power switch 20 is turned on, and output adjustment corresponding to the right induction heating unit is output by the display operation unit 5. Adjust. The control unit of the inverter board 9 causes a high-frequency current to flow through the right induction heating coil 6 to generate magnetic lines of force from the induction heating coil 6 to heat the pan, and at the same time, the control unit also drives the fan 12. The driven fan 12 takes in air for cooling from the air inlet 16 and cools it by blowing cooling air to the inverter board 9 and each induction heating coil. Thereafter, the air is exhausted from the exhaust port 17 provided in the rear part on the top plate of the main body 2 to the outside air.

  That is, as shown by the arrows in FIG. 1 or FIG. 3, the air sucked from the intake port 16 is discharged from the exhaust port 17 to the outside air after cooling the inverter board 9 and each induction heating coil.

  Now, as described above, since the intake port 16 takes in the air around the induction heating cooker, it also sucks dust in the air together with the air. The dust that has been sucked in passes through the intake duct 18 and accumulates on the inverter board 9 to be cooled, which may cause an electrical failure.

  Therefore, the inventors of the present invention have considered to scrape off dust adhering to the intake filter by using the movement of the front operation unit and the movement of the door of the grill cabinet, and as a result, the following examples were obtained.

  Hereinafter, the dust scraping structure according to the present invention will be described in detail with reference to the drawings.

  FIG. 4 is an exploded perspective view for explaining the opened state of the front operation unit 3 and the positions of the dustproof filter 21 and the cleaning member 22 in Example 1, and shows a state in which the front operation unit 3 and the dustproof filter 21 are removed. .

  FIGS. 5 and 6 are for explaining the action of the cleaning member 22 cleaning the dustproof filter 21 in accordance with the opening / closing operation of the front operation unit 3 in this embodiment. FIG. 5 shows a state in which the front operation unit 3 is closed, and FIG. 6 shows a state in which the front operation unit 3 is fully opened. Some parts are omitted for explanation.

  Further, FIGS. 7 and 8 are for explaining the shapes of the dustproof filter 21 and the cleaning member 22. The broken lines in FIG. 7 indicate that small holes opened throughout the dustproof filter are omitted for simplicity. The arrows shown in FIG. 8 indicate the flow of intake air.

  4, 5, and 6, in this embodiment, the front operation unit 3 is attached to the operation unit case 20 at the lower end by the fixing pin 23 illustrated in FIGS. 5, 6, 7, and 8. The operation surface is exposed to the user side by rotating around the fixing pin 23. As shown in FIG. 7, the dust filter 21 is provided with a plurality of small holes on an arcuate surface. As shown in FIG. 4, the dust filter 21 is located inside the front end of the front operation unit 3 and outside the intake port 16. The air intake 16 is fixed so as to cover it.

  In this embodiment, the center of the circular arc of the dustproof filter 21 is the axial center of the fixed pin 23, the diameter of the small hole is about 3 mm, and a punched wire net having an aperture ratio of about 50% is used.

  The cleaning member 22 has an opening 22a formed of a frame-like structure (frame) as shown in FIG. The cleaning member 22 is fixed to the lower part of the front operation unit 3 so as to protrude to the inside of the body. However, as shown by the arrow in FIG. The structure is such that no matter where the cleaning member 22 is located during movement, the intake air is not hindered. Further, the tip 24 of the cleaning member 22 is attached with a brush 24a composed of a plurality of fluffs having a length of about 5 mm.

First, the operation due to the provision of the dust filter 21 will be described.
By providing a plurality of small holes, the dust filter 21 can separate and capture dust sucked together with the cooling air and prevent entry into the airframe.
In this embodiment, a plurality of small holes are used, but a mesh-like wire net or a plurality of slits may be used. Moreover, since it is provided inside the container from the front surface of the front operation unit 3, even if the captured dust adheres and accumulates on the surface of the dust filter 21, it does not hide the front operation unit 3 and impair the appearance. Further, as will be described later, when the dust filter 21 is formed in an arc shape, the force applied to the brush when the cleaning member 22 cleans becomes constant, thereby further improving the cleanability.

Next, the effect | action by having provided the cleaning member 22 is demonstrated.
Since the cleaning member 22 is fixed to the front operation unit 3 when the front operation unit 3 is rotated and opened to operate the device, the cleaning member 22 is also rotated simultaneously with the rotation opening and closing. The brush 24a attached to the distal end portion 24 of the cleaning member 22 moves along an arcuate locus by the rotational movement of the front operation unit 3. This movement causes the arc radius of the dustproof filter 21 to be the same arc radius as the trajectory. It can be scraped off with a certain force along the surface to be attached. That is, by providing the cleaning member 22, it is possible to clean the dustproof filter 21 using the power when operating the front operation unit 3. That is, every time the user opens and closes the front operation unit 3, the dustproof filter 21 is cleaned without noticing.

  As described above, according to the present embodiment, there is no need to newly add a power generation device for cleaning the dustproof filter, and the user can operate the front operation unit 3 to operate the device. This operation makes it possible to clean the dustproof filter 21 without making the user aware that the dustproof filter 21 is being cleaned.

  Moreover, since it is not necessary for the user to remove and clean the dustproof filter as in Patent Document 1, even if the dustproof filter 21 is installed in a place with no visibility so as not to impair the appearance, it can be cleaned without any problem. . Further, the cleaning member 22 is provided with a frame-shaped opening 22a, so that the cleaning member 22 can be connected to the front operation unit 3 with a simple structure as well as obstructing the air flow path at any position in the movable range. can do. Further, the dust removed from the dustproof filter 21 by the cleaning member 22 can be more easily dropped and discharged out of the container.

9 and 10 show the configuration of the second embodiment.
The second embodiment is a modified example in which the dustproof filter 21b and the power transmission device 25 are used instead of the dustproof filter 21 and the cleaning member 22 of the first embodiment, and the same components as those in the first embodiment are denoted by the same reference numerals. Will be omitted.

  FIG. 9 is a cross section taken along a plane including the circumferential direction of the gear to show the configuration of the present embodiment shown in FIG.

  9 and 10, the dust filter 21 b has a plate shape with a plurality of small holes as shown in FIG. 10. A leaf spring 26g is attached to a connecting portion between the dustproof filter 21b and the main body. The leaf spring 26g is configured to incline and press the dustproof filter 21b so as to cover the air intake port 16 from the lower surface of the main body 2 so as to be located inside the front end of the front operation unit 3 and outside the air intake port 16. The other side of the dustproof filter 21 b is in contact with the second gear 28 attached to the side wall of the operation unit case 20. The second gear 28 meshes with a rack 29 attached to the side wall of the operation unit case 20 via the first gear 27. The gears 27 and 28 and the rack 29 are referred to as a power transmission device 25.

  The diameter of the small hole formed in the dustproof filter 21b according to the present embodiment is about 3 mm, and a punched wire net having an aperture ratio of about 50% is used. The power transmission device 25 is for transmitting the opening / closing operation of the front operation unit 3 to the dustproof filter 21 b, and includes a first gear 27, a second gear 28 and a rack 29. The rack 29 is fixed to the side surface of the front operation unit 3 and operates simultaneously with the opening / closing operation of the front operation unit 3. The first gear 27 and the second gear 28 rotate around a rotation shaft fixed to the operation unit case 20. When the front operation unit 3 rotates, the rack 29 rotates the first gear 27, and the first gear 27 rotates the second gear 28. The second gear 28 moves the end of the dustproof filter 21b, and when the end is displaced to some extent, the end of the dustproof filter 21b is separated from the second gear 28, and the dustproof filter 21b is restored by the restoring force of the leaf spring 26. Return to position. By this reciprocating motion, the dust filter 21b is vibrated, and the dust accumulated on the dust collecting surface of the dust filter 21b can be dropped to the lower side of the container.

  As described above, according to the present embodiment, the dust filter 21b itself is vibrated to perform cleaning, so there is no need to provide a cleaning device such as a cleaning member in the vicinity of the dust filter, and the area around the dust filter can be simplified. Pressure loss can be reduced. Further, by attaching the dust filter 21b with the dust collection surface facing downward and inclined with respect to the vertical surface, the dust can be easily dropped from the filter surface. In addition, by providing the power transmission device 25, it is possible to obtain a damping effect that suppresses rapid rotation when the front operation unit 3 is opened. Thereby, the front operation part 3 opens and closes gently, and it can improve component durability and usability.

FIG. 11 shows the configuration of the third embodiment.
The third embodiment is a modification using the cleaning member 22c and the power transmission device 25c instead of the cleaning member 22 of the first embodiment, and the same components as those of the first embodiment are denoted by the same reference numerals and description thereof is omitted. And

  As shown in FIG. 12, the cleaning member 22c has a cylindrical shape in which a plurality of brushes 22d attached to the end of a frame (frame) are combined, and rotates around the central axis of the cylinder outside the dust filter 21. It is provided as follows. The brush 22d provided at the tip is composed of a plurality of fluffs having a length of about 5 mm. Further, since the opening 22e is formed between the brushes 22d, the intake air flow passing between the frames is not hindered.

  The power transmission device 25c is for transmitting the opening / closing operation of the front operation unit 3 to the cleaning member 22c, and includes a first gear 27c, a second gear 28c, a third gear 30c, and a rack 29c. The rack 29c is fixed to the side surface of the front operation unit 3, and operates simultaneously with the opening / closing operation of the front operation unit 3. The first gear 27 c and the second gear 28 c rotate around a rotation shaft fixed to the operation unit case 20.

  When the front operation unit 3 rotates, the rack 29c rotates the first gear 27c, and the first gear 27c rotates the second gear 28c. The second gear 28c further rotates the third gear 30c attached to the cleaning member 22c to rotate the cleaning member 22c. At this time, the number of teeth of the first gear 27c, the second gear 28c, and the third gear 30c is adjusted, and the cleaning member 22c rotates a plurality of times until the front operation unit 3 is fully opened. Like that.

  As described above, according to the present embodiment, when the cleaning member 22c rotates at least once, the plurality of brushes provided on the cleaning member 22c cleans the dustproof filter 21, so that dust attached to the surface of the dustproof filter 21 is removed with the brush. The number of drops can be increased, and the cleaning property can be further improved.

FIG. 13 shows the configuration of the fourth embodiment.
The fourth embodiment is a modification using the slide rail 32 and the power transmission device 25d instead of the front operation unit 3 and the power transmission device 25c of the third embodiment, and the same reference numerals are given to the same components as those of the third embodiment. The description will be omitted.

  In FIG. 13, it is for demonstrating the mechanism which rotates the cleaning member 22c using the power transmission device 25d from the slide rail 32, The front operation part 3 and the operation part case 20 are removed, and a grill warehouse is partially It is a partial cross-sectional view that is cut away. In addition, some parts are omitted for convenience.

  As shown in FIG. 11, the slide rail 32 is used to open and close the grill door 31, and is provided with one rail that is movable forward and backward and its storage portion on the lower left and right sides of the grill cabinet 4, and is connected to the grill door 31.
