[0009] (Background to this disclosure) In recent years, in order to improve the strength of a housing of a cooking appliance, a plurality of housings have been combined.

[0010] For example, in the induction heating cooker described in Patent Document 1, a housing is formed by connecting a U-shaped first outer case and an L-shaped second outer case. Specifically, the bottom surface of the first outer case and the bottom surface of the second outer case are connected. In such a configuration, it is difficult to improve the strength of the connection portion where the first outer case and the second outer case are connected.

[0011] Therefore, the inventors of the present invention have conducted extensive research to improve the strength of a cooking appliance formed by combining multiple housings, and have arrived at the present disclosure.

[0012] Hereinafter, an embodiment of the present disclosure will be described with reference to the accompanying drawings.

The center line CL1 is an imaginary line that divides the first housing 31 evenly in the front-rear direction, and a first distance D1 from the front face 31b of the first housing to the center line CL1 is equal to a second distance D2 from the back face 31c of the first housing 31 to the center line CL1.

[0032] The through hole 8 has, for example, a circular shape in a plan view. Note that the through hole 8 is not limited to a circular shape and may have any shape. For example, the through hole 8 may have an elliptical shape in a plan view.

[0033] [Details of the case configuration] The detailed configuration of the housing 3 will be described with reference to Figs. 4 to 10. Fig. 4 is a schematic perspective view of an example of the housing 3. Fig. 5 is a schematic plan view of an example of the housing 3. Fig. 6 is a schematic perspective view showing an example of the second housing 32. Fig. 7 is a schematic perspective view showing an example of the third housing 33. Fig. 8 is a schematic perspective view showing the second housing 32 and the third housing 33. Fig. 9 is a schematic perspective view showing the second housing 32 and the third housing 33. Fig. 10 is a schematic cross-sectional view of the second housing 32 and the third housing 33 shown in Fig. 8 taken along line AA.

[0034] As shown in FIGS. 4 and 5, the housing 3 includes a first housing 31, a second housing 32, and a third housing 33.

[0035] The first housing 31 has a box shape with an open top and a rectangular shape in a plan view. A through hole 8 for drawing air into the first housing 31 is provided in the bottom surface 31a of the first housing.

[0036] The second housing 32 has a box shape with an open top and front, and has a rectangular shape in a plan view. The second housing 32 has smaller dimensions in the left-right direction (X direction) and front-rear direction (Y direction) than the first housing 31. The second housing 32 also has a smaller dimension in the front-rear direction (Y direction) than the third housing 33. The second housing 32 is disposed below the first housing 31 and adjacent to the third housing 33.

[0037] For example, the depth dimension of second housing 32 in the front-to-rear direction (Y direction) of cooking appliance 1 is 0.4 to 0.8 times the depth dimension of third housing 33. Preferably, the depth dimension of second housing 32 is 0.5 to 0.75 times the depth dimension of third housing 33. More preferably, the depth dimension of second housing 32 is 0.6 to 0.7 times the depth dimension of third housing 33.

[0038] The third housing 33 has a box shape with an open top and front, and has a rectangular shape in a plan view. The third housing 33 has a smaller dimension in the left-right direction (X direction) than the first housing 31. The third housing 33 is disposed below the first housing 31 and adjacent to the second housing 32.

[0039] The detailed configuration of the second housing 32 will be described with reference to FIG.

[0040] As shown in FIG. 6, the second housing 32 includes a first bottom portion 32a, two first side walls 32b and 32c, and a first rear portion 32d.

[0041] The first bottom surface portion 32a is a portion that constitutes the bottom surface of the second housing 32. For example, the first bottom surface portion 32a has a rectangular flat plate shape in a plan view.

[0042] The two first side walls 32b, 32c are portions constituting side surfaces extending upward from the end of the first bottom surface portion 32a in the left-right direction (X direction) of the second housing 32. The first side wall portion 32b extends upward from the end of the first bottom surface portion 32a adjacent to the third housing 33. The first side wall portion 32c extends upward from the end of the first bottom surface portion 32a opposite to the side adjacent to the third housing 33. The two first side walls 32b, 32c are provided in a direction perpendicular to the first bottom surface portion 32a. The two first side walls 32b, 32c face each other. For example, the two first side walls 32b, 32c have a rectangular flat plate shape when viewed from the left-right direction (X direction) of the second housing 32.

[0043] The first sidewall portions 32b, 32c are provided with first flanges 34b, 34c that protrude in a direction intersecting with the first sidewall portions 32b, 32c. The first flanges 34b, 34c protrude in a direction (X direction) perpendicular to the first sidewall portions 32b, 32c.

[0044] The first flange 34b protrudes from an upper end of the first side wall portion 32b toward the outside of the first side wall portion 32b. Specifically, the first flange 34b protrudes from an upper end of the first side wall portion 32b toward the third housing 33. The first flange 34c protrudes from an upper end of the first side wall portion 32c toward the outside of the first side wall portion 32c. For example, the first flanges 34b, 34c have a plate shape.

[0045] Further, the first flanges 34b, 34c are provided with mounting holes 9b for mounting to the first housing 31 and / or the third housing 33. In this embodiment, the mounting holes 9b provided in the first flange 34b are used for mounting to the first housing 31 and the third housing 33. The mounting holes 9b provided in the first flange 34c are used for mounting to the first housing 31.

[0046] The second housing 32 has a first engagement protrusion 36a and a second engagement protrusion 36b that engage with the third housing 33. The first engagement protrusion 36a and the second engagement protrusion 36b are inserted into a first engagement hole 37a and a second engagement hole 37b provided in a second side wall portion 33b of the third housing 33, which will be described later.

[0047] The first engagement protrusion 36a and the second engagement protrusion 36b protrude further toward the third housing 33 than the first side wall portion 32b in the left-right direction (X direction) of the second housing 32. The first engagement protrusion 36a is provided on the front side of the second housing 32. The second engagement protrusion 36b is provided on the rear side of the second housing 32 than the first engagement protrusion 36a. In the up-down direction (Z direction) of the second housing 32, the first engagement protrusion 36a and the second engagement protrusion 36b are provided at a lower position than the first flange 34b. Also, the first engagement protrusion 36a is provided at a higher position than the second engagement protrusion 36b.

[0048] In this embodiment, a front flange 34a that protrudes toward the third housing 33 is provided at the end of the first side wall portion 32b on the front side of the second housing 32. The first engagement protrusion 36a is provided integrally with the front flange 34a. As a result, the front end of the second housing 32 is connected to the third housing 33, making it easy to align the front surface of the third housing 33 with the front end of the second housing 32. In addition, since the first engagement protrusion 36a does not need to be formed of a separate member, the strength of the first engagement protrusion 36a itself is improved.

[0049] In this embodiment, the second engagement protrusion 36b is provided integrally with the first rear portion 32d on the rear side of the second housing 32. This eliminates the need to form the second engagement protrusion 36b as a separate member, improving the strength of the second engagement protrusion 36b itself.

[0050] The first engagement protrusion 36a and the second engagement protrusion 36b have, for example, a flat plate shape. For example, the first engagement protrusion 36a and the second engagement protrusion 36b have a shape that tapers in the protruding direction.

[0051] In this embodiment, the second engagement protrusion 36b has a raised portion 36c that rises in the thickness direction (Y direction) of the second engagement protrusion 36b. The raised portion 36c is formed by deforming the second engagement protrusion 36b into a convex shape by depressing the second engagement protrusion 36b in the thickness direction. For example, the raised portion 36c is formed in a linear shape when viewed from the thickness direction of the second engagement protrusion 36b. For example, the raised portion 36c is a rib. The raised portion 36c can improve the mechanical strength of the second engagement protrusion 36b.

[0052] The raised portion 36c may be provided on the first engagement projection 36a.

[0053] The first rear portion 32d is a portion that constitutes the rear surface of the second housing 32. The first rear portion 32d extends upward from the end portion on the far side of the first bottom surface portion 32a in the front-rear direction (Y direction) of the second housing 32. The first rear portion 32d is provided in a direction (Z direction) perpendicular to the first bottom surface portion 32a. The first rear portion 32d connects the two opposing first side wall portions 32b, 32c.

[0054] As shown in Fig. 9, first side wall portion 32b has bent portion 32e on the rear side. Bent portion 32e is formed by bending a portion of first side wall portion 32b on the rear side. Bent portion 32e is provided upward from the center of first side wall portion 32b in the height direction (Z direction) of cooker 1. Bent portion 32e is bent toward a side away from third housing 33 in the left-right direction (X direction) of cooker 1, and is connected to first rear portion 32d in a state where it is overlapped on first rear portion 32d.

[0055] In the height direction (Z direction) of the cooker 1, the second engagement protrusion 36b is disposed at a lower position than the first engagement protrusion 36a. This allows for a stable connection between the second housing 32 and the third housing 33. Furthermore, in the height direction (Z direction) of the cooker 1, the front side of the first side wall portion 32b is connected to the third housing 33 at a higher position than the rear side of the first side wall portion 32b, so that misalignment in the height direction (Z direction) at the front sides of the second housing 32 and the third housing 33 can be suppressed.

[0056] The first rear portion 32d is provided with a rear flange 34d that protrudes in a direction intersecting with the first rear portion 32d. The rear flange 34d protrudes from the upper end of the first rear portion 32d toward the outside of the first rear portion 32d. Specifically, the rear flange 34d protrudes in a direction perpendicular to the first rear portion 32d (X direction). The rear flange 34d is provided with an attachment hole 9b for attachment to the first housing 31. The attachment hole 9b provided in the rear flange 34d is provided on the first side wall portion 32b side of the center part of the first rear portion 32d in the left-right direction (X direction) of the second housing 32.

[0057] The detailed configuration of the third housing 33 will be described with reference to FIG.

[0058] As shown in FIG. 7, the third housing 33 includes a second bottom portion 33a, two second side walls 33b and 33c, and a second rear portion 33d.

[0059] The second bottom surface portion 33a is a portion that constitutes the bottom surface of the third housing 33. For example, the second bottom surface portion 33a has a rectangular flat plate shape in a plan view.

[0060] The two second side walls 33b, 33c are portions constituting side surfaces extending upward from the end of the second bottom surface portion 33a in the left-right direction (X direction) of the third housing 33. The second side wall portion 33b extends upward from the end of the second bottom surface portion 33a adjacent to the second housing 32. The second side wall portion 33c extends upward from the end of the second bottom surface portion 33a opposite to the side adjacent to the second housing 32. The two second side walls 33b, 33c are provided in a direction perpendicular to the second bottom surface portion 33a. The two second side walls 33b, 33c face each other. For example, the two second side walls 33b, 33c have a rectangular flat plate shape when viewed from the left-right direction (X direction) of the third housing 33.

[0061] The second side wall portions 33b, 33c are provided with second flanges 35b, 35c protruding in a direction intersecting with the second side wall portions 33b, 33c. The second flange 35b protrudes from the upper end of the second side wall portion 33b toward the outside of the second side wall portion 33b. The second flange 35c protrudes from the upper end of the second side wall portion 33c toward the inside of the second side wall portion 33c. Specifically, the second flanges 35b, 35c protrude in a direction perpendicular to the second side wall portions 33b, 33c (X direction). The second flanges 35b, 35c are provided with mounting holes 9c for mounting to the first housing 31.

[0062] The third housing 33 is provided with a first engagement hole 37a and a second engagement hole 37b which engage with the first engagement protrusion 36a and the second engagement protrusion 36b of the second housing 32. The first engagement hole 37a and the second engagement hole 37b are provided in the second side wall portion 33b.

[0063] The first engagement hole 37a and the second engagement hole 37b protrude further toward the third housing 33 than the first side wall portion 32b in the left-right direction of the second housing 32. The first engagement hole 37a is provided on the front side of the third housing 33. The second engagement hole 37b is provided on the rear side of the third housing 33 than the first engagement hole 37a. In the up-down direction (Z direction) of the third housing 33, the first engagement hole 37a and the second engagement hole 37b are provided at a position lower than the second flange 35b. Also, the first engagement hole 37a is provided at a position higher than the second engagement hole 37b.

[0064] For example, the first engagement hole 37a and the second engagement hole 37b are slits having a longitudinal direction in the up-down direction (Z direction) of the third housing 33.

[0065] The second rear portion 33d is a portion that constitutes the rear surface of the third housing 33. The second rear portion 33d extends upward from the end portion on the far side of the second bottom surface portion 33a in the front-rear direction (Y direction) of the third housing 33. The second rear portion 33d is provided in a direction that intersects with the second bottom surface portion 33a and the two second side walls 33b, 33c. The second rear portion 33d connects the two opposing second side walls 33b, 33c.

[0066] The connection between the second housing 32 and the third housing 33 will be described with reference to FIGS.

[0067] As shown in FIGS. 8 to 10, the second housing 32 and the third housing 33 are adjacent to each other, and the first side wall portion 32b of the second housing 32 is attached to face the second side wall portion 33b of the third housing 33.

[0068] The second housing 32 includes a first flange 34b protruding from the first side wall portion 32b toward the third housing 33, and the third housing 33 includes a second flange 35b protruding from the second side wall portion 33b toward the second housing 32. The first flange 34b is attached to the second flange 35b by a mounting fixture 9a and mounting holes 9b and 9c.

[0069] The first flange 34b is disposed so as to overlap the second flange 35b. The mounting holes 9b of the first flange 34b and the mounting holes 9c of the second flange 35b overlap in the vertical direction (Z direction). The mounting fixtures 9a are inserted into the mounting holes 9b and 9c. For example, the mounting fixtures 9a are screws or bolts. The first flange 34b and the second flange 35b are connected by the mounting fixtures 9a inserted into the mounting holes 9b and 9c.

[0070] A first engagement protrusion 36a and a second engagement protrusion 36b are provided on the first side wall portion 32b of the second housing 32. A first engagement hole 37a and a second engagement hole 37b are provided on the second side wall portion 33b of the third housing 33. The first engagement protrusion 36a and the second engagement protrusion 36b are inserted into the first engagement hole 37a and the second engagement hole 37b, respectively. As a result, the first side wall portion 32b and the second side wall portion 33b are connected by the first engagement protrusion 36a and the second engagement protrusion 36b inserted into the first engagement hole 37a and the second engagement hole 37b.

[0071] By connecting the second housing 32 and the third housing 33 as described above, the first side wall portion 32b of the second housing 32 is attached to face the second side wall portion 33b of the third housing 33. This makes it possible to improve the strength of the connection between the second housing 32 and the third housing 33.

[0072] Further, a gap 38 is provided between the first side wall portion 32b of the second housing 32 and the second side wall portion 33b of the third housing 33. For example, the gap 38 is formed by an air layer.

[0073] The dimension L1 of the gap 38 is, for example, not less than 5 mm and not more than 10 mm. Preferably, the dimension L1 of the gap 38 is not less than 6 mm and not more than 9 mm. More preferably, the dimension L1 of the gap 38 is not less than 7 mm and not more than 8 mm.

[0074] By providing the gap 38 between the second housing 32 and the third housing 33 in this manner, the heat from the heating device 5 housed in the third housing 33 is less likely to be transmitted to the second housing 32.

[0075] In this embodiment, the rear flange 34d is provided with mounting holes 9b for mounting the second housing 32 to the first housing 31. The mounting holes 9b provided in the rear flange 34d are provided closer to the first side wall portion 32b than the center portion of the first rear portion 32d in the left-right direction (X direction) of the second housing 32. This allows the first housing 31 and the second housing 32 to be mounted closer to the portion where the second housing 32 and the third housing 33 are connected, thereby improving strength.
