(gasket)
Returning to FIG. 1, a gasket 38 is provided on the back surface 36 of the door 8. The gasket 38 used in the cooking utensil 2 of the present embodiment will be described with reference to FIGS. 7 to 9C.

FIG. 7 is a rear view of the door 8, showing the back surface 36 of the door 8. The gasket 38 shown in FIG. 7 is a sealing member attached to the back surface 36 of the door 8 and seals between the door 8 and the housing 6. When the heating chamber 4 is closed by the door 8, that is, when the door 8 is closed, the gaps on both sides are sealed with the gasket 38 where the back surface 36 of the door 8 and the front surface 40 of the housing 6 face each other. As a result, steam or the like generated in the heating chamber 4 is prevented from leaking to the outside of the heating cooker 2.

As shown in FIG. 7, the gasket 38 of the present embodiment is an annular member that is continuous along the outer frame of the door 8.

A sectional view taken along the line AA of FIG. 7 is shown in FIG. FIG. 8 shows a state in which the door 8 is open, that is, a state in which the door 8 is opened. The front surface 26 of the door 8 is shown on the front side of the paper surface in FIG. 8, and the back surface 36 of the door 8 is shown on the back side of the paper surface. The front surface 26 corresponds to the outer surface of the door 8 and the back surface 36 corresponds to the inner surface of the door 8.

As shown in FIG. 8, the back surface 36 of the door 8 is composed of a door body 41 and a choke cover 42.

The door main body 41 is a main body of the door 8. The door body 41 forms a choke structure 44 at its tip. The choke structure 44 is a structure for preventing the transmission of microwaves, and a plurality of comb-shaped metal plates are arranged.

The choke cover 42 is a cover member that covers the choke structure 44. The choke cover 42 is attached to the door body 41 at a position covering the choke structure 44.

A groove 46 is formed between the door body 41 and the choke cover 42. A gasket 38 is attached to the groove 46. The gasket 38 attached to the groove 46 seals between the door body 41 and the choke cover 42. The gasket 38 projects in the C direction, which is a direction away from the door 8, and is configured to be in contact with the front surface 40 of the housing 6.

The detailed configuration of the gasket 38 will be described with reference to FIGS. 9A to 9C. 9A to 9C are cross-sectional views showing different states of the gasket 38, respectively. 9A corresponds to the open state of the door 8, and FIGS. 9B and 9C correspond to the closed state of the door 8. FIG. 9B shows a state in which the door 8 is being closed, and FIG. 9C shows a state after the door 8 is closed.

As shown in FIG. 9A, the gasket 38 includes a mounting portion 48, a first rising portion 50, and a second rising portion 52.

The mounting portion 48 is a portion for mounting the gasket 38 on the door 8. The mounting portion 48 of this embodiment is fitted to the tip of the choke cover 42.

Both the first rising portion 50 and the second rising portion 52 are portions that rise from the mounting portion 48. The first rising portion 50 and the second rising portion 52 stand up in the C direction, which is a direction away from the door 8.

The first rising portion 50 is a portion that rises from the first position P1 in the mounting portion 48. The first rising portion 50 faces the facing wall 54 of the door main body portion 41. The facing wall 54 is a portion curved in the middle of the door main body 41 so as to enter the inside of the door 8.

The first rising portion 50 has a first extending portion 50A and a second extending portion 50B. The first extending portion 50A is a portion extending from the mounting portion 48, and the second extending portion 50B is a portion extending inclined from the first extending portion 50A.

The first extending portion 50A is arranged at a distance from the facing wall 54 and extends along the facing wall 54. That is, the first extending portion 50A does not come into contact with the facing wall 54. The second extending portion 50B extends obliquely from the first extending portion 50A toward the facing wall 54, and the tip of the second extending portion 50B comes into contact with the facing wall 54. According to such a configuration, a gap S1 is generated between the first rising portion 50 and the facing wall 54.

Similarly, in the mounting portion 48, a plurality of protrusions 56 are formed at locations facing the facing wall 54. The protrusion 56 contacts the facing wall 54, and the portion of the mounting portion 48 other than the protrusion 56 does not contact the facing wall 54. Similar to the first rising portion 50 described above, a gap S2 is generated between the mounting portion 48 and the facing wall 54.

The second rising portion 52 is a portion of the mounting portion 48 that rises from a second position P2 different from the first position P1. The second rising portion 52 has a connecting portion 52A, a first inclined portion 52B, a second inclined portion 52C, and a bent portion 52D.

The connecting portion 52A is a portion that rises from the mounting portion 48. The connecting portion 52A of the present embodiment rises vertically from the mounting portion 48. The connecting portion 52A is connected to the first inclined portion 52B.

The first inclined portion 52B is a portion inclined and extending from the connecting portion 52A. The first inclined portion 52B is inclined in the D1 direction, which is a direction approaching the first rising portion 50 described above. The D1 direction of the present embodiment is a direction approaching the rotation axis (not shown) of the door 8.

The second inclined portion 52C is a portion inclined and extending from the first inclined portion 52B. The second inclined portion 52C is inclined in the direction opposite to that of the first inclined portion 52B, that is, in the D2 direction which is a direction away from the first rising portion 50. The D2 direction of the present embodiment is a direction away from the rotation axis of the door 8.

By having the first inclined portion 52B and the second inclined portion 52C, the second rising portion 52 is formed in a "dogleg shape". The point at which the first inclined portion 52B and the second inclined portion 52C are connected is defined as the bending point 53. In the opened state of the door 8 shown in FIG. 9A, neither the first inclined portion 52B nor the second inclined portion 52C is in contact with the first rising portion 50. A gap S3 is formed between the first rising portion 50 and the second rising portion 52. The gap S3 is a bag-shaped space that is not closed when the door 8 is opened and is exposed to the outside.

As shown by the dotted line in FIG. 9A, when the first rising portion 50 and the second rising portion 52 are projected perpendicularly to the door 8, the rising portions 50 and 52 partially overlap each other.

The bent portion 52D is a portion bent inward from the second inclined portion 52C. By providing such a bent portion 52D, it is possible to prevent the second rising portion 52 from standing excessively in the C direction away from the door 8.

As shown in FIG. 9B, as the door 8 is closed with respect to the housing 6, the second rising portion 52 of the gasket 38 comes into contact with the front surface 40 of the housing 6. The second rising portion 52 is compressed and curved by being pushed by the front surface 40 of the housing 6. As described above, since the second rising portion 52 is formed in a “dogleg” shape, the first curved portion 52B and the second curved portion 52C are curved in the direction of approaching each other, and the bending point 53 is It moves in the direction approaching the first rising portion 50. Therefore, as shown in FIG. 9B, the first curved portion 52B comes into contact with the first rising portion 50, and the gap S3 is closed.

As described above, in the opened state of the door 8, the second rising portion 52 does not contact the first rising portion 50, and in the closed state of the door 8, the second rising portion 52 contacts the first rising portion 50, resulting in a gap. S3 is blocked. As a result, the repulsive force of the gasket 38 is weak in the stage until the second rising portion 52 comes into contact with the first rising portion 50, whereas the repulsive force becomes strong in the stage after the contact. In this way, the gasket 38 can exhibit a stepwise cushioning property.

Further, the gap S3 is closed, but since the first rising portion 50 and the second rising portion 52 are not integral members, the closing property of the gap S3 is weak. Therefore, even after the first rising portion 50 and the second rising portion 52 come into contact with each other, the repulsive force of the gasket 38 does not become excessively strong. As a result, the desired cushioning property of the gasket 38 can be exhibited.

Here, as a comparative example, it is conceivable that the first rising portion 50 and the second rising portion 52 are integrally formed, and the gap S3 is always closed to form a hollow portion. However, in this configuration, since the hollow portion is always a closed space, the internal pressure of the hollow portion may increase due to the temperature rise, and the repulsive force of the gasket 38 may become excessively strong. Further, in order to form the hollow portion, the manufacturing method of the gasket 38 is limited to extrusion molding, and it cannot be manufactured by another manufacturing method. On the other hand, in the gasket 38 of the present embodiment, since the gap S3 is not a gap that is always closed, it is possible to prevent the repulsive force of the gasket 38 from becoming excessively strong. Further, since it is not necessary to form a hollow portion in the gasket 38, the gasket 38 can be manufactured not only by extrusion molding but also by other methods such as press working and injection molding.

Further, as shown in FIG. 9A, since there is a partially overlapping region when the first rising portion 50 and the second rising portion 52 are projected perpendicularly to the door 8, as shown in FIG. 9B, the first rising portion 50 and the second rising portion 52 are projected onto the door 8. 2 The rising portion 52 can be reliably brought into contact with the first rising portion 50.

When the gasket 38 is further compressed from the state shown in FIG. 9B, the first rising portion 50 is pushed by the second rising portion 52 and moves in the D1 direction approaching the facing wall 54, as shown in FIG. 9C. As described above, the first rising portion 50 forms a gap S1 with the facing wall 54, and the gap S1 becomes smaller as the first rising portion 50 moves. By providing such a gap S1, the compressive force generated by the second rising portion 52 being pushed from the housing 6 can be absorbed by the first rising portion 50. As a result, the degree of increase in the repulsive force of the gasket 38 can be moderated, and the gasket 38 can exhibit a desired cushioning function.

Further, since the second rising portion 52 of the present embodiment has the connecting portion 52A, it is possible to further absorb the compressive force caused by the second rising portion 52 being pushed from the housing 6.

In the state shown in FIG. 9C, the space between the housing 6 and the door 8 is sealed by the gasket 38 to prevent steam and the like in the heating chamber 4 from leaking to the outside.

As described above, the cooking cooker 2 of the embodiment includes a housing 6 forming a heating chamber 4 for accommodating an object to be heated, a door 8 for opening and closing the heating chamber 4, and a gasket 38. The gasket 38 is an elastic material that is attached to the door 8 and seals between the closed door 8 and the front surface 40 of the housing 6 facing the door 8. The gasket 38 includes a mounting portion 48 attached to the back surface 36 which is the inner surface of the door 8, a first rising portion 50, and a second rising portion 52. The first rising portion 50 and the second rising portion 52 are portions of the mounting portion 48 that rise in the C direction away from the door 8 from the first position P1 and the second position P2, respectively. The second rising portion 52 has a first inclined portion 52B and a second inclined portion 52C. The first inclined portion 52B is inclined in the D1 direction approaching the first rising portion 50, and the second inclined portion 52C is inclined in the D2 direction extending from the first inclined portion 52B and away from the first rising portion 50. In the closed state of the door 8, the second rising portion 52 is pushed by the front surface 40 of the housing 6 and comes into contact with the first rising portion 50.

According to such a configuration, the second rising portion 52 does not contact the first rising portion 50 when the door 8 is open, and contacts the first rising portion 50 when the door 8 is closed. As a result, the gasket 38 can exhibit a desired cushioning function.

Further, according to the cooking device 2 of the embodiment, the door 8 includes a door main body 41 and a choke cover 42. The door body 41 is a member that forms a choke structure 44 for preventing leakage of microwaves. The choke cover 42 is a member attached to the door body 41 so as to cover the choke structure 44. The gasket 38 is arranged in the groove 46 between the door body 41 and the choke cover 42. According to such a configuration, the gasket 38 can be arranged in the groove 46 between the choke cover 42 and the door main body 41 to exhibit the sealing property while preventing the leakage of microwaves by the choke structure 44.

In the above description, the case where the cross-sectional shapes of the first inclined portion 52B and the second inclined portion 52C in the second rising portion 52 extend linearly has been described, but the case is not limited to such a case. For example, as shown in FIGS. 10 and 11, the cross-sectional shape of the second inclined portion 58 may be curved. Further, as shown in FIG. 11, the bent portion 59 may be curved in a curved line.

Next, the side wall 12A is joined to the support wall 17. Specifically, as shown in FIG. 14C, the side wall 12A is placed on the first wall portion 60 of the support wall 17 and joined. In the present embodiment, the side wall 12A and the support wall 17 are mechanically joined by using the protruding flange hole 70. Specifically, a screw is inserted into the protruding flange hole 70 and screw-joined. Not limited to screw joining, any joining method such as caulking joining or welding may be adopted.

As shown in FIG. 14C, a gap 72 is formed between the side wall 12A and the first wall portion 60. The positions of the guide lines 68A and 68B described above are set in advance so that the adhesive portion 21A reaches the gap 72 between the side wall portion 12A and the first wall portion 60. Therefore, as shown in FIG. 14C, the gap 72 is filled and sealed by the adhesive portion 21A.

By sealing the gap 72 with the adhesive portion 21A in this way, the joint between the side wall 12A and the first wall portion 60 can be strengthened. Further, steam or the like is generated in the heating chamber 4 during the operation of the cooking cooker 2, and it is possible to prevent such steam or the like from leaking to the outside of the heating chamber 4 through the gap 72. Internal parts (not shown) such as a motor and a control circuit are arranged below the support wall 17, and a gap 72 is sealed where there is a risk of failure if water droplets of steam adhere to such internal parts. By doing so, it is possible to prevent water droplets from adhering to the internal parts through the gap 72. As a result, it is possible to suppress the failure of the internal parts of the cooking cooker 2 and improve the reliability of the cooking cooker 2.

In FIGS. 14A to 14C, the adhesive portion 21A and the side wall 12A on the left side when the heating chamber 4 is viewed from the front have been described, but the same coating method is applied to the adhesive portion 21B on the right side. Specifically, as shown in FIG. 15, the adhesive portion 21B adheres the outer peripheral edge portion 27 of the lower wall 16 and the support wall 17 by the adhesive portion 21B, and the adhesive portion 21B has a gap 74 between the side wall 12B and the first wall portion 60. The adhesive portion 21B is applied so as to reach the position where the adhesive portion 21B is filled. As a result, it is possible to prevent leakage of steam or the like through the gap 74 while increasing the joint strength between the side wall 12B and the support wall 17 by tightening the screws inserted into the protruding flange hole 76. As a result, it is possible to suppress the failure of the internal parts of the cooking device 2 and improve the reliability of the cooking device 2.

As shown in FIG. 15, the width of the adhesive portion 21B is the width W2.

As described above, in the cooking cooker 2 of the present embodiment, the adhesive portions 21A and 21B have a gap 72 between the left and right side walls 12A and 12B and the first wall portion 60 from the outer peripheral edge portion 27 of the lower wall 16. The regions extending to 74 are provided as the first region and the second region on the left and right, respectively. As a result, it is possible to suppress the failure of the internal parts of the cooking cooker 2 and improve the reliability of the cooking cooker 2.

Returning to FIG. 13, a fourth wall portion 65 is provided on the front portion (that is, the front side of the paper surface) of the support wall 17. The fourth wall portion 65 is a portion provided at the position closest to the door 8 and is continuously formed from the first wall portion 60 described above. Similar to the first wall portion 60, the fourth wall portion 65 is adhered to the lower wall 16 by the adhesive portion.

FIG. 16 is an enlarged cross-sectional view of the periphery of the adhesive portion 77 that adheres the fourth wall portion 65 to the lower wall 16. As shown in FIG. 16, the adhesive portion 77 adheres the outer peripheral edge portion 27 of the lower wall 16 and the support wall 17, and has a width of W3.

While the above-mentioned adhesive portions 21A and 21B correspond to the first region and the second region, the adhesive portion 77 corresponds to the third region extending in the left-right direction so as to connect the first region and the second region. .. In the present embodiment, the width W1 of the first region and the width W2 of the second region are set to be uniformly longer than the width W3 of the third region. As a result, the lateral widths of the adhesive portions 21A and 21B can be sufficiently secured, and the gaps 72 and 74 between the side walls 12A and 12B and the first wall portion 60 can be more reliably sealed.
