  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a perspective view of an induction heating cooker according to a first embodiment of the present invention, FIG. 2 is a perspective view of a first air inlet cover and a second air inlet cover, and FIG. 3 is attached with a second air inlet cover. The perspective view when doing is shown.

  In FIG. 1, a main body 1 is a stationary type that is used by being placed on a stand such as a kitchen, and the side surface, rear surface, and bottom surface of the main body 1 are constituted by an outer case 4. The upper surface of the main body 1 is covered with a top frame 3 made of a metal component around the top plate 2 on which a pan is placed and made of crystallized glass. A heating coil 5 constituting induction heating means for induction heating the pan is disposed inside the main body 1.

  The front surface of the main body 1 at the lower part of the top frame 3 includes a door 7 of a cooking chamber 6 that includes a sheathed heater as a heating element in the cabinet, and cooks ingredients, and a front panel 10 that covers the front of the main body on the side of the door 7. Most of it is covered. The door 7 is opened and closed with a handle. A circuit unit 8 that supplies high-frequency power to the heating coil 5 and a cooling fan 9 that blows cooling air to the heating coil 5 and the circuit unit 8 are disposed in front of the circuit unit 8 inside the front panel 10. Yes.

In addition, an air inlet 11 that communicates with the cooling fan 9 is provided on the bottom surface of the outer case 4. A plurality of holes are provided in the first air inlet cover 12 configured to cover the air inlet portion 11 and fixed to the bottom surface of the outer case 4, and these holes serve as second air inlets 14. The first air inlet cover 12 is fixed using screws and screwed to the bottom surface of the outer case 4. The plurality of holes, which are the second air inlets 14 provided in the first air inlet cover 12, have finger thicknesses as a guide so that the fingers do not enter the body 1 and touch the cooling fan to cause injury. The maximum dimension is about 10 mm or less. Furthermore, if it is made into a substantially lattice shape and has a hole of about 10 mm square or less, dust and dust entering the main body 1 can be further suppressed. The shape of the air intake port portion 11 is such that the first air intake port cover 12 is fixed to the outside of the main body 1 and there is no possibility of a finger entering, so the area of the air intake port portion 11 is larger than that of the first air intake port cover 12. The number of holes may be one or more, round holes, or a substantially lattice shape. The first air inlet cover 12 serves to cover an edge portion such as the air inlet portion 11 of the outer case 4 made of a metal plate. A plurality of holes are also provided in the second intake port cover 13 that is held on the bottom surface of the outer case 4 and provided opposite to the first intake port cover 12, and these holes serve as third intake ports 15. The plurality of holes, which are the third intake ports 15 provided in the second intake port cover 13, do not get injured when a finger enters the main body 1 and touches the cooling fan, like the second intake port 14. As described above, the maximum part size is set to about 10 mm or less with the thickness of the finger as a guide. Furthermore, if it is made into a substantially lattice shape and has a hole of about 10 mm square or less, dust and dust entering the main body 1 can be further suppressed.

  1, 2, and 3, the second air inlet cover 13 is held on the first air inlet cover 12 fixed to the bottom surface of the outer case 4 with a substantially L-shaped cross section when viewed from the front of the main body 1. A plurality of one protrusion 17 is provided and held. The second air inlet cover 13 slides substantially parallel to the bottom surface of the outer case 4 from the front surface of the outer case 4 and is held by a plurality of first protrusions 17 as shown in FIG. Thereby, the 2nd inlet cover 13 can be attached or detached from the front surface of the main body 1 with the main body 1 installed. Furthermore, by fixing the first air inlet cover 12 to the bottom surface of the outer case 4, it is possible to suppress the entry of dust and dust into the main body 1 even when the second air inlet cover 13 is forgotten to be attached. Further, the two roles of holding the second air inlet cover 13 can be realized by only the first air inlet cover 12.

  Similarly, a plurality of second protrusions (not shown) having a substantially L-shaped cross section when viewed from the front of the main body 1 are provided and held on the bottom surface of the outer case 4 to hold the second air inlet cover 13. Can slide from the front surface of the outer case 4 substantially in parallel to the bottom surface of the outer case 4 and can be held by a plurality of second protrusions so that it can be detachable. Thereby, the 2nd inlet cover 13 can be attached or detached from the front surface of the main body 1 with the main body 1 installed. Furthermore, the structure which hold | maintains the 2nd inlet port cover 13 can be implement | achieved, without providing components separately only to hold | maintain a 2nd inlet port cover.

  In the state in which the second air inlet cover 13 is attached, the outside air first passes through the third air inlet 15 provided in the second air inlet cover 13 and then the first air provided in the first air inlet cover 12. 2, passes through the intake port 14, passes through the intake port 11 provided on the bottom surface of the outer case 4, is taken into the cooling fan 9, and is blown as cooling air to cool the heating coil 5 and the circuit unit 8. .

  Further, as shown in FIG. 2, by making the hole constituting the third air inlet 15 finer than the hole constituting the second air inlet 14, dust and dust adhering when the outside air is inhaled, It becomes easy to adhere to the 2nd inlet cover 13 which exists outside, and it becomes difficult to adhere to the 1st inlet cover 12 compared with this. The second air inlet cover 13 is a detachable structure, can be removed from the main body 1 and cleaned, and dust and dust are less likely to adhere to the first air inlet cover 12 fixed to the main body 1. Dust and dust that enter the main body 1 during long-term use can be reduced. Dust and dust entering the main body 1 adheres to the circuit unit 8 and absorbs moisture and oil and can cause a tracking phenomenon. Therefore, reducing dust and dust entering the main body leads to an improvement in quality. .

  Further, as shown in FIG. 1, the holes constituting the third air inlet 15 and the holes constituting the second air inlet 14 are formed in a substantially lattice shape so that the outside air is sucked in by using the same shape. Dust and dust adhering to the air intake are more likely to adhere to the second air intake cover 13 on the outside, making it less likely to adhere to the first air intake cover 12 as compared with this, and in addition, configuring the third air intake 15. Since the shape of the hole and the hole constituting the second intake port 14 are the same and the intake area is the same, the intake capacity is reduced when outside air passes through the third intake port 15 and passes through the second intake port 14. Can be suppressed. As a result, the intake capacity can be improved and the cooling performance can be improved, so that the heating coil and the circuit unit can be prevented from being heated and damaged, leading to an improvement in quality.

(Embodiment 2)
FIG. 4 shows a sectional view of an induction heating cooker according to the second embodiment of the present invention. Since the basic configuration of the present embodiment is the same as that of the first embodiment, different points will be mainly described. The same elements as those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIG. 4, the first embodiment is different from the first embodiment in that it includes a front panel 10 constituting the front surface of the main body, and the second air inlet cover 13 rises toward the front surface of the main body 1 to form a fourth air inlet 16. It is the point which has the structure which has the inclined surface 20 in which the several hole to be formed is formed, and the lower end of the front panel 10 and the upper end of the inclined surface 20 correspond. As a result, in addition to intake from the bottom surface of the main body 1, it is possible to intake air from below the front surface of the main body 1 by the fourth intake port 16 provided on the inclined surface 20, and the intake capacity can be improved. Further, by adopting a configuration in which the lower end of the front panel 10 and the upper end of the inclined surface 20 coincide with each other, a gap between the front panel 10 and the inclined surface 20 of the second intake port cover 13 is taken in when outside air is sucked from the lower front of the main body 1. Can be suppressed, and dust and dust can be prevented from being sucked into and intruded into the main body 1 from the gap between the front panel 10 and the inclined surface 20. If the fourth intake port 16 has a substantially lattice shape and a shape of about 10 mm square or less, it is possible to further suppress the intrusion of dust or dust into the main body 1.

  Furthermore, by providing the inclined surface 20, the inclined surface 20 can be confirmed from the front surface of the main body 1 when the second intake port cover 13 is mounted, and when the second intake port cover is not mounted, the inclined surface 20 is missing. Since it can be confirmed that the second intake port cover 13 is mounted, it can be easily confirmed.

(Embodiment 3)
FIG. 5 is a perspective view of the second air inlet cover in the third embodiment of the present invention. Since the basic configuration of the present embodiment is the same as that of the first embodiment, different points will be mainly described. The same elements as those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIGS. 1 and 4, the second air inlet cover 13 is attached to the first air inlet cover 12 or the bottom surface of the outer case 4 by being inserted backward from the front side of the main body 1. As shown in the figure, the inclined surface 20 exposed on the front surface of the main body 1 has an outer surface of the finger hook portion 21 that hooks the fingertip when the second intake port cover 13 is removed at a substantially central portion sandwiched between the fourth intake ports 16. 20 is a space in which the fingertip fits as a recess 22 that is recessed in the back, and the tip is provided as a downward rib. The second air inlet cover 13 can be removed from the first air inlet cover 12 or the bottom surface of the outer case 4 by hooking the fingertip on the finger hook 21 so as to put the fingertip into the recess 22 and pulling it out in the forward direction of the main body 1.

  In addition, as shown in FIG. 5, the outer shape of the finger hanging portion 21 is made to coincide with the inclined surface 20, and since it does not come forward from the inclined surface 20, it is possible to reduce the unexpected touching of the finger hanging portion 21 when the main body 1 is used for cooking, This prevents the second air inlet cover 13 from being unintentionally removed.

  Since the upper portion of the finger hook portion 21 and the upper side of the fourth intake port 16 are substantially aligned with the substantially central portion sandwiched between the fourth intake port 16 and the back portion is disposed as the recess 22, the outer surface is changed. When removing the second air inlet cover 13 with the recessed portion 22 as a mark, the part to be removed can be easily identified by hooking and pulling the fingertip, and the second air inlet cover 13 can be easily attached and detached without hesitation. be able to. In addition, since the upper side of the range of the fourth intake port 16 of the second intake port cover 13 and the upper side of the finger hook portion 21 substantially coincide with each other, it is possible to achieve an appearance in which the hook portion is not conspicuous.

  The concave wall surface 23 that forms the concave portion 22 at the back of the finger hook portion 21 provided on the inclined surface 20 constituting the second air inlet cover 13 is configured not to provide a hole that communicates with the inside of the main body 1.

Thereby, since there is no route for directly sucking air into the main body 1 from the recess 22, the fingertip touches when removing the second air inlet cover 13, and it is difficult for dust to accumulate in the finger hook 21 and the recess 22 at the back thereof. When the second air inlet cover 13 is removed, the fingertip hardly touches dust, and the second air inlet cover 13 can be removed comfortably.

(Embodiment 4)
FIG. 6: shows sectional drawing of the induction heating cooking appliance in 4th Embodiment in this invention. Since the basic configuration of the present embodiment is the same as that of the first embodiment, different points will be mainly described. The same elements as those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  5 and 6, the second air inlet cover 13 has substantially rectangular openings on the top and bottom surfaces, and both openings are configured so that the openings facing each other are shifted in the front-rear direction so that the opening on the bottom surface is in front of the top surface. And is configured in a substantially lattice shape so that the inside and the outside of the main body 1 communicate with each other in a space between the inclined surfaces rising to the upper surface from the bottom to the rear. The cooling fan 9 is located behind the main body 1 with respect to the third air inlet 15, and by forming an inclined surface that rises rearward, resistance can be reduced when the outside air is sucked into the main body 1. When the inclined surface is not provided, the outside air passes through the third air inlet 15 and enters the main body upward, and then is sucked backward by the cooling fan 9 so that the path is upward and backward. . On the other hand, by providing the inclined surface, the outside air is sucked by the cooling fan 9 in an oblique direction on the rear side of the main body, so that pressure loss during intake can be suppressed.

  As described above, the induction cooking device according to the present invention can attach and detach the second air inlet cover, which is a dustproof filter, from the front surface of the outer case to the bottom surface of the outer case in a state where the main body is installed. Therefore, it can be applied to uses such as cooking appliances having a dustproof filter.
