Description

Heating cooker

Technical Field

The present disclosure relates to a heating cooker.

Background

A heating cooker having an operation unit that has a user interface (user interface) surface and can be stored therein for inputting a user instruction is known (for example, refer to japanese patent No. 4992864). In the conventional cooking device, the operation unit includes a unit body, an opening/closing panel, and an operation module (module).

The opening/closing panel is a front panel of the operation unit. The lower end of the opening/closing panel is rotatably supported by the unit main body, and the upper end of the opening/closing panel is detachable from the unit main body. The front end of the operation module is rotatably supported by the upper end of the opening/closing panel.

The operation unit is disposed on a front portion of a housing of the heating cooker. When the upper end portion of the opening and closing panel moves forward, the operation module is exposed from the unit main body.

Disclosure of Invention

However, in the case of the conventional heating cooker described above, the positioning accuracy of the opening/closing panel with respect to the unit main body is partially different in the operation unit.

Specifically, the opening/closing panel rotates about a rotation shaft disposed on the lower end side. That is, the lower end portion of the opening/closing panel is rotatably supported by the unit main body. Therefore, the lower end portion of the opening/closing panel is positioned with high accuracy with respect to the unit main body.

The upper end of the opening/closing panel is not supported by the unit main body, and moves away from or close to the unit main body. Therefore, the positioning accuracy with respect to the unit main body is low.

If the positioning accuracy of the opening/closing panel with respect to the unit main body is locally different in this way, for example, the appearance of the heating cooker may be deteriorated.

For example, in the case of the conventional heating cooker described above, the grill door covering the front surface of the grill chamber and the opening/closing panel of the operation unit in the closed state are configured as an appearance of the heating cooker integrated by being arranged in the left and right directions. That is, the grill door and the opening/closing panel function as an appearance panel.

In this case, a level difference may be generated between the upper portion of the opening and closing panel and the grill door due to a low positioning accuracy of the upper end portion of the opening and closing panel with respect to the unit main body. If such a step occurs, the appearance of the front surface of the heating cooker deteriorates.

The present disclosure relates to a heating cooker including a unit including: a unit main body; and an opening/closing panel having a lower end portion rotatably supported by the unit main body and an upper end portion detachable from the unit main body. The present disclosure aims to improve the positioning accuracy of the upper end portion of the opening/closing panel with respect to the unit main body in such a heating cooker.

A heating cooker according to an aspect of the present disclosure includes: a housing; and an opening/closing unit attached to a front portion of the housing. The opening/closing unit includes: a unit body mounted to the housing; an opening and closing panel; and a push latch mechanism.

The opening/closing panel has a lower end portion supported by the unit main body so as to be rotatable about a first rotation axis. The push-type latch mechanism is disposed outside a circular area defined by a circle that passes through a midpoint between the first rotation axis and the upper end of the opening and closing panel, with the first rotation axis as a center, when viewed along the first rotation axis. A push-type latch mechanism detachably couples an upper end portion of the opening/closing panel to the unit main body.

According to the present disclosure, in the heating cooker, the upper end portion of the opening/closing panel can be positioned with respect to the unit main body with higher accuracy.

Detailed Description

A heating cooker according to an aspect of the present disclosure includes: a housing; and an opening/closing unit attached to a front portion of the housing. The opening/closing unit includes: a unit body mounted to the housing; an opening and closing panel; and a push latch mechanism.

The opening/closing panel has a lower end portion supported by the unit main body so as to be rotatable about a first rotation axis. The push-type latch mechanism is disposed outside a circular area defined by a circle that passes through a midpoint between the first rotation axis and the upper end of the opening and closing panel, with the first rotation axis as a center, when viewed along the first rotation axis. A push-type latch mechanism detachably couples an upper end portion of the opening/closing panel to the unit main body.

According to an aspect of the present disclosure, in the heating cooker, the upper end portion of the opening/closing panel can be positioned with respect to the unit main body with higher accuracy.

The opening/closing unit may be an operation unit for operating the heating cooker. In this case, the operation unit includes a user interface surface and an operation module. The distal end portion of the operation module is supported by the upper end portion of the opening/closing panel so as to be rotatable about a second rotation axis parallel to the first rotation axis. In the operation unit, when the opening and closing panel is rotated and the operation module is rotated, the user interface surface is exposed from the inside of the unit main body.

The push latch mechanism may be disposed at one end of the operation unit in a direction along the first rotation axis.

In the above-described case, the heating cooker may further include a grill chamber that is disposed in the vicinity of one end of the operation unit with respect to the other end of the operation unit in the direction along the first rotation axis, and that accommodates and heats the heating target.

The push latch mechanism may have a latch (striker) provided on the opening/closing panel. The unit main body may have a vent hole that communicates the inside of the case with the outside. The lock pin may have a claw portion facing the outside of the heating cooker.

When the push-type latch mechanism is disposed at one end portion of the operation unit in the direction along the first rotation axis, the push-type latch mechanism includes a first guide pin and a second guide pin disposed at a rear end portion of the operation module and protruding in one direction and the other direction along the second rotation axis.

The unit body has a first guide slit and a second guide slit that guide the first guide pin and the second guide pin, respectively, so that the operation module rotates in synchronization with the rotation of the opening/closing panel. When the opening/closing panel is in a closed state, the second guide slit displaces the second guide pin so that the first rotation shaft and the second rotation shaft are parallel to each other.

The heating cooker may further include an appearance plate attached to the opening/closing panel.

Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

Fig. 1 is a perspective view showing an external appearance of a heating cooker 10 according to the present embodiment. Fig. 2 is an exploded perspective view of the front portion of heating cooker 10 with operation unit 20 removed.

In the present disclosure, arrows in fig. 1 to 14 indicate the front, rear, left, and right of the heating cooker 10. That is, the grill chamber 30 and the operation unit 20 are disposed on the front side of the heating cooker 10. Top plate 12 is disposed above heating cooker 10. The left and right in the present disclosure are the left and right, respectively, when the heating cooker 10 is viewed from the front. The top plate 12, the operation unit 20, and the grill chamber 30 will be described later.

As shown in fig. 1, the heating cooker 10 includes: a top plate 12 for placing a cooking container (not shown) accommodating a heating target; and a housing 14 below the top plate 12. The heating target is, for example, a food material. The casing 14 houses an induction heating coil (not shown) for inductively heating the cooking container placed on the top plate 12. The housing 14 also has an operation unit 20 mounted on a front side portion thereof for inputting a user's instruction.

As shown in fig. 1 and 2, the heating cooker 10 has a grill chamber 30. The grill chamber 30 has a grill space 30a therein, and heats a heating target accommodated in the grill space 30 a. The grill chamber 30 is disposed on the left side of the operation unit 20. The grill chamber 30 includes a grill door 32 that covers the front opening of the grill space 30 a. In fig. 2, the grill door 32 is omitted.

The grill door 32 is a rectangular plate-like member. When the user moves the grill door 32 forward, the front surface opening of the grill space 30a is opened. Thereafter, when the user moves the grill door 32 rearward, the front surface opening of the grill space 30a is closed. The grill door 32 is provided with a handle 34 for a user to hold.

Fig. 3 is a perspective view of the operation unit 20 in an open state. Fig. 4A and 4B are exploded perspective views of the operation unit 20. Fig. 5A and 5B are right side views of the operation unit 20. Fig. 6A and 6B are left side views of the operation unit 20.

Fig. 4A, 5A, and 6A illustrate the operation unit 20 in a closed state. Fig. 4B, 5B, and 6B show the operation unit 20 in an open state. That is, in the present embodiment, the operation unit 20 is an openable unit that can take an open state and a closed state.

As shown in fig. 2 to 4B, the operation unit 20 includes a unit main body 42, an opening/closing panel 44, and an operation module 46. The unit body 42 is mounted to the housing 14. The opening/closing panel 44 is supported by the unit main body 42. The operation module 46 is supported by the opening/closing panel 44. A detachable exterior panel 47 (see fig. 2) is attached to the opening/closing panel 44.

As shown in fig. 2, the unit body 42 is attached to an attachment surface 14a disposed on the front side of the housing 14. The details of the mounting method will be described later.

As shown in fig. 4A and 4B, the unit main body 42 is a box-shaped member having an opening at a front portion. The unit main body 42 includes a storage space 42a therein for storing the operation module 46 in a state where the operation unit 20 is closed. The housing space 42a is defined by a right wall portion 42b, a left wall portion 42c, and a rear wall portion 42d of the unit main body 42.

As shown in fig. 3 to 6B, the opening/closing panel 44 includes a body portion 44a, a right wall portion 44B, and a left wall portion 44c. The main body 44a detachably supports the exterior panel 47. The right wall 44b and the left wall 44c project rearward from the left and right ends of the body 44a, respectively.

A through hole 44d and a through hole 44e are formed in the lower end of the right wall 44b and the lower end of the left wall 44c, respectively. Support pins 48 are inserted into the through holes 44d and 44e, respectively.

A support arm portion 42e and a support arm portion 42f are formed at the left and right lower ends of the unit main body 42 so as to protrude forward, respectively. The support arm portions 42e and 42f are provided with engagement holes 42r, respectively.

The support pins 48 inserted into the through holes 44d and 44e are engaged with the engagement holes 42r. Thus, the lower end portion of the opening/closing panel 44 is supported by the unit main body 42 so as to be rotatable about the first rotation axis C1 extending in the left-right direction.

As shown in fig. 3, the operation module 46 includes a user interface surface 46a for inputting a user instruction. The user interface surface 46a includes a plurality of operation buttons 46b and a display unit 46c. The display portion 46c is a liquid crystal display.

As shown in fig. 3 to 6B, the distal end portion of the operation module 46 is supported by the upper end portion of the opening/closing panel 44 so as to be rotatable about a second rotation axis C2 parallel to the first rotation axis C1. Specifically, a through hole 44f and a through hole 44i are formed in the upper end portion of the right wall portion 44b and the upper end portion of the left wall portion 44c, respectively. Support pins 50 are inserted into the through holes 44f and 44i, respectively.

Support pins 50 passed through holes 44f and 44i are engaged with engagement holes (not shown) provided on both left and right surfaces of the front end portion of operation module 46. Thus, the distal end portion of the operation module 46 is supported by the opening/closing panel 44 so as to be rotatable about the second rotation axis C2.

As shown in fig. 2, 4A, 5A, and 6A, when the operation unit 20 is in the closed state, the operation block 46 is turned around the second rotation axis C2 and approaches the back side of the main body portion 44A of the opening/closing panel 44 (therefore, cannot be visually confirmed in the drawings). In this case, the operation module 46 is housed in the housing space 42a of the unit main body 42, and the user interface surface 46a faces the rear wall portion 42d of the unit main body 42.

As shown in fig. 3, 4B, 5B, and 6B, when the operation unit 20 is in the open state, the operation module 46 rotates about the second rotation axis C2 and is separated from the main body portion 44a of the opening/closing panel 44. In this case, the operation module 46 is exposed from the housing space 42a of the unit body 42, and the user interface surface 46a faces upward.

The operation of the operation module 46 is interlocked with the turning operation of the opening/closing panel 44 about the first rotation axis C1.

Specifically, as shown in fig. 4B, a first guide pin 52 and a second guide pin 54 are disposed at the rear end of the operation block 46. The first guide pin 52 and the second guide pin 54 protrude in one direction and the other direction along the direction (left-right direction) of the second rotation axis C2, respectively.

That is, the first guide pin 52 protrudes in one direction (right direction) along the direction of the second rotation axis from the right rear end portion of the operation module 46. The second guide pin 54 protrudes from the left rear end portion of the operation module 46 in the other direction (left direction) along the direction of the second rotation axis.

The right wall portion 42b and the left wall portion 42c of the unit main body 42 are provided with a first guide slit 42h and a second guide slit 42i, respectively. The first guide slit 42h and the second guide slit 42i are elongated through holes penetrating the right wall portion 42b and the left wall portion 42C along the second rotation axis C2, respectively. The first guide pin 52 and the second guide pin 54 are fitted in the first guide slit 42h and the second guide slit 42i so as to slide along the first guide slit 42h and the second guide slit 42i, respectively.

As shown in fig. 5A, 5B, 6A, and 6B, the first guide slit 42h and the second guide slit 42i have an arc-like shape having a center located in front of the unit main body 42.

The upper end of the first guide slit 42h and the upper end of the second guide slit 42i are positioned forward of the lower end of the first guide slit 42h and the lower end of the second guide slit 42i, respectively.

As shown in fig. 4B, one roller 55 is disposed near the right rear end portion of the operation module 46, and the other roller 55 is disposed near the left rear end portion of the operation module 46. The two rollers 55 can rotate about the second rotation axis C2. A guide rib 42q is provided on the rear wall portion 42d of the unit main body 42. The two rollers 55 are in contact with the guide rib 42q and can roll on the guide rib 42q.

The operation module 46 operates as follows by the first guide pin 52, the second guide pin 54, the first guide slit 42h, the second guide slit 42i, the roller 55, and the guide rib 42q.

When the opening/closing panel 44 starts to rotate about the first rotation axis C1 from the closed state shown in fig. 4A, 5A, and 6A, the roller 55 starts to roll on the guide rib 42q. The first guide pin 52 and the second guide pin 54 start to move upward along the first guide slit 42h and the second guide slit 42i, respectively. In synchronization with this, the operation module 46 starts to rotate about the second rotation axis C2 and starts to move away from the main body portion 44a of the opening and closing panel 44.

When the opening/closing panel 44 further rotates, the first guide pin 52 and the second guide pin 54 move forward while moving upward along the first guide slit 42h and the second guide slit 42i, respectively. Thereby, the operation module 46 moves to the outside of the unit main body 42.

Finally, as shown in fig. 3, 4B, 5B, and 6B, the opening/closing panel 44 is opened. At this time, the operation module 46 is exposed from the housing space 42a of the unit body 42, and the user interface surface 46a faces upward.

In this way, the unit body 42 has the first guide slit 42h and the second guide slit 42i that guide the first guide pin 52 and the second guide pin 54, respectively, so that the operation module 46 rotates in synchronization with the rotation of the opening/closing panel 44.

As shown in fig. 4A and 4B, the unit main body 42 includes a leaf spring 56 that biases the opening/closing panel 44 forward to automatically open the opening/closing panel 44.

As shown in fig. 5A and 6A, a push-type latch mechanism 58 is provided in the operation unit 20 to maintain the opening/closing panel 44 in a closed state.

Fig. 7 is a front view of the unit main body of the operation unit 20. Fig. 8A is a partial sectional view along the line 8A-8A of fig. 7 showing the operation unit 20 in the closed state. Fig. 8B is a partial sectional view of the operation unit 20 in the open state taken along the line 8a-8a of fig. 7.

As shown in fig. 8A and 8B, the push-type latch mechanism 58 includes a lock pin (striker) 60 and a latch (latch) 62 that detachably holds the lock pin 60.

When the locking pin 60 is inserted into the latch 62, the latch 62 grips the locking pin 60. When the lock pin 60 is further pressed from this state, the latch 62 releases the grip of the lock pin 60, and the lock pin 60 is separated from the latch 62.

The latch 60 of the push latch mechanism 58 is disposed on the opening/closing panel 44, and the latch 62 is disposed on the unit main body 42. Thereby, the push-type latch mechanism 58 detachably couples the opening/closing panel 44 to the unit main body 42.

The push latch mechanism 58 is disposed at an end portion (right end portion) of the operation unit 20, not at the center of the operation unit 20 in a direction (left-right direction) along the first rotation axis C1. In other words, the push latch mechanism 58 is disposed at a position of the operation unit 20 farthest from the grill chamber 30 (see fig. 1).

As shown in fig. 4A, 4B, 5B, and 6B, the lock pin 60 is provided on one of the side cover 64 and the side cover 66, not on the opening/closing panel 44. The side covers 64 and 66 are provided on the right wall 44b and the left wall 44c of the opening/closing panel 44, respectively. The operation module 46 rotates about the second rotation axis C2 between the side covers 64 and 66.

As shown in fig. 5B and 6B, when the operation unit 20 is in the open state, the side covers 64 and 66 suppress the intrusion of foreign matter below the operation module 46.

As shown in fig. 7, the through- holes 42j and 42k are formed in the rear wall portion 42d of the cell body 42. As shown in fig. 5A and 6A, when the operation unit 20 is in the closed state, the side covers 64 and 66 protrude rearward of the unit main body 42 through the through holes 42j and 42 k.

As shown in fig. 3 to 4B, the latch 60 of the push latch mechanism 58 is provided on the side cover 64 located at the farthest position from the grill chamber 30. The latch 62 of the push latch mechanism 58 is disposed at the right end of the housing space 42a of the unit main body 42 to engage with the latch pin 60. With this arrangement position, the push latch mechanism 58 can be prevented from thermally deforming due to heat from the grill chamber 30.

The lock pin 60 has a claw portion 60a facing outward to hook the latch 62. However, depending on the environment in which cooking device 10 is used, claw portion 60a may preferably face inward.

In the present embodiment, "inside" of heating cooker 10 means a direction from the left end or the right end of heating cooker 10 toward the center line of heating cooker 10 in the left-right direction. The "outer side" of heating cooker 10 refers to a direction from the center line in the left-right direction of heating cooker 10 toward the left end or the right end of heating cooker 10.

The left-right direction of the heating cooker 10 is a direction along a first rotation axis C1 and a second rotation axis C2 described later.

As shown in fig. 5A, a plurality of vent holes 42s are formed in the right wall portion 42b of the unit main body 42 of the operation unit 20. The plurality of vent holes 42s communicate the inside of the housing 14 with the outside. This allows outside air to be introduced into the casing 14 of the heating cooker 10.

The outside air enters the housing space 42a of the unit main body 42 along the side cover 64, and then enters the case 14 through the vent hole 42s. When the claw portion 60a of the lock pin 60 faces outward, dust and the like contained in the outside air may be accumulated on the claw portion 60a. Therefore, when the heating cooker 10 is used in an environment with a lot of dust, the claw portion 60a is preferably directed inward.

As shown in fig. 8B, the push latch mechanism 58 is disposed outside the circular region CR as viewed along the first rotation axis C1. The circular region CR is a region defined by a circle that is centered on the first rotation axis C1 and passes through a midpoint between the first rotation axis C1 and the upper end 44h of the opening/closing panel 44.

This improves the accuracy of positioning the upper end portion of the opening/closing panel 44 with respect to the unit main body 42 when the operation unit 20 is in the closed state, as compared with the case where the push latch mechanism 58 is disposed in the circular region CR.

Specifically, the lower end portion of the opening/closing panel 44 is supported by the support arm portions 42e and 42f of the unit main body 42, and the positioning accuracy with respect to the unit main body 42 is relatively high.

The upper end portion of the opening/closing panel 44 is not supported by the unit main body 42, and moves away from the unit main body 42 or moves closer to the unit main body 42. Therefore, the positioning accuracy with respect to the unit main body 42 is relatively low.

As a result, the positioning accuracy of the opening/closing panel 44 with respect to the unit main body 42 is partially different. The closer to the upper end 44h, the lower the positioning accuracy. That is, the closer the opening/closing panel 44 is to the upper end 44h, the more easily the opening/closing panel is shaken.

In this way, if the positioning accuracy of the opening/closing panel 44 with respect to the unit main body 42 is locally different, the aesthetic appearance of the heating cooker 10 may be deteriorated.

In the present embodiment, as shown in fig. 1, an appearance plate 47 is attached to the opening/closing panel 44 of the operation unit 20 in the closed state. The appearance plate 47 is arranged side by side with the grill door 32 of the grill chamber 30 to constitute the front surface of the heating cooker 10. That is, the grill door 32 is a part of the outer panel of the heating cooker 10.

Due to the lower positioning accuracy of the upper end portion of the opening and closing panel 44 with respect to the unit main body 42, there is a possibility that a level difference is generated between the upper end portion of the exterior plate 47 and the upper end portion of the grill door 32. If such a difference in height occurs, the front surface of the heating cooker 10 is less aesthetically pleasing.

Then, as shown in fig. 8A, the operation unit 20 includes a push latch mechanism 58. The push latch mechanism 58 couples the upper end portion of the opening/closing panel 44 to the unit main body 42 when the operation unit 20 is in the closed state. This improves the positioning accuracy of the upper end portion of the opening/closing panel 44 with respect to the unit main body 42. This is a result compared with the case where the push latch mechanism 58 is not present, or the case where the push latch mechanism 58 is present in the circular region CR shown in fig. 8B.

There is another advantage that the push-type latch mechanism 58 couples the upper end portion of the opening/closing panel 44 to the unit main body 42. The push-latch mechanism 58 is disposed outside the circular region CR shown in fig. 8B.

Therefore, the stroke (stroke) required to engage the lock pin 60 with the latch 62 is smaller than in the case where the push latch mechanism 58 is located inside the circular region CR. The stroke required for releasing the engagement is also reduced. As a result, the user can easily open or close the opening/closing panel 44 by pushing the appearance plate 47 in a small stroke.

As described above, the push latch mechanism 58 is disposed at one end portion (right end portion) in the direction (left-right direction) along the first rotation axis C1 of the operation unit 20. Therefore, when the operation unit 20 is in the closed state, the left portion of the opening/closing panel 44 is positioned forward of the right portion of the opening/closing panel 44 by being coupled by the push-type latch mechanism 58.

This is caused by the opening/closing panel 44 being biased by the plate spring 56. As a result, the first rotation axis C1 and the second rotation axis C2 are in a twisted positional relationship, and the opening/closing panel 44 and the appearance plate 47 are slightly twisted.

To cope with this, as shown in fig. 6A, the second guide slit 42i of the unit body 42 displaces the second guide pin 54 at the left end portion of the operation block 46 rearward. In fig. 6A, the second guide pin 54 in the case where the second guide slit 42i is not present is indicated by a two-dot chain line as a second guide pin 54 a.

The first rotation axis C1 and the second rotation axis C2 become parallel to each other by the second guide pin 54 and the second guide slit 42i. As a result, the open/close panel 44 is not twisted when the operation unit 20 is in the closed state.

Hereinafter, the attachment of the operation unit 20 to the housing 14 will be described.

As shown in fig. 2, the operation unit 20 is fixed to the front portion of the housing 14 by a plurality of screws 70 inserted from the front toward the rear.

Fig. 9 is a partial right side view of the heating cooker in a state where the operation unit 20 is mounted to the housing.

As shown in fig. 9, the mounting surface 14a is disposed on the front side of the housing 14. The operation unit 20 is fixed to the attachment surface 14a by a plurality of screws 70. Spacers 72A to 72D are disposed between operation unit 20 and mounting surface 14a.

Fig. 10 is a perspective view of the spacers 72A to 72D. Fig. 11 is a rear view of the unit main body 42 in a state where the spacers 72A to 72D are arranged. Fig. 12 is a partial perspective view showing an adjustment portion of the unit main body 42. Fig. 13A is a partial perspective view of the unit main body 42 in a state where the spacers 72A to 72D are arranged. Fig. 13B is a partial perspective view of the unit main body 42 in a state where the spacers 72A to 72D are arranged.

As shown in fig. 10 and 11, the spacers 72A to 72D are wedge-shaped cam members. Of the four spacers, spacer 72A and spacer 72D have the same shape, and spacer 72B and spacer 72C have the same shape. The spacers 72A, 72D and the spacers 72B, 72C have line-symmetrical shapes. The spacers 72A to 72D have substantially the same function.

As shown in fig. 11, the spacers 72A to 72D adjust the distance between a part of the outer peripheral edge of the unit body 42 and the mounting surface 14a of the housing 14, respectively. The spacer 72A is disposed at an upper portion of the flange portion 42n extending outward from the right wall portion 42 b. The spacer 72A adjusts the distance between the upper portion of the flange portion 42n and the housing 14. Hereinafter, an upper portion of the flange portion 42n is referred to as an adjustment portion 74A.

The spacer 72B is disposed at a lower portion of the flange portion 42 n. The spacer 72B adjusts the distance between the lower portion of the flange portion 42n and the housing 14. Hereinafter, the lower portion of the flange portion 42n is referred to as an adjustment portion 74B.

The spacer 72C is disposed at an upper portion of the flange portion 42p extending outward from the left wall portion 42C. The spacer 72C adjusts the distance between the upper portion of the flange portion 42p and the housing 14. Hereinafter, an upper portion of the flange portion 42p is referred to as an adjustment portion 74C.

The spacer 72D is disposed at a lower portion of the flange portion 42 p. The spacer 72D adjusts the distance between the lower portion of the flange portion 42p and the housing 14. Hereinafter, a lower portion of the flange portion 42p is referred to as an adjustment portion 74D. The adjustment portions 74A to 74D have substantially the same shape.

As shown in fig. 9, 10, and 12, the spacers 72A to 72D each include a reference surface 72A and a cam surface 72b. The reference surface 72a is a surface that contacts the mounting surface 14a of the housing 14. The cam surface 72b is a surface inclined in the front-rear direction with respect to the reference surface 72 a.

The adjustment portions 74A to 74D of the unit main body 42 are respectively provided with follower surfaces 74A that are parallel to and in contact with the cam surfaces 72b of the corresponding ones of the spacers 72A to 72D.

The cam surface 72b of each of the spacers 72A to 72D has a step portion 72c. The driven surface 74A of each of the adjustment portions 74A to 74D has a convex portion 74b that engages with the step portion 72c. This suppresses the occurrence of sliding between the cam surface 72b and the follower surface 74a.

In order to suppress wear of the driven surface 74a, the unit body 42 is made of a material harder than the material of the spacers 72A to 72D. The spacers 72A to 72D are made of, for example, polyacetal (POM) resin in order to ensure high slidability of the cam surface 72b with respect to the driven surface 74a.

As shown in fig. 9, 10, and 12, the spacers 72A to 72D each include a groove 72D (see fig. 11) through which the screw 70 passes. As described above, the screw 70 is inserted from the front to the rear. The groove portions 72d of the spacers 72A and 72C have a U shape covering the screw 70 extending from the front to the rear from below. The groove portions 72D of the spacers 72B and 72D have an inverted U shape that covers the screw 70 extending from the front to the rear from above.

Through holes 74c are formed in the adjustment portions 74A to 74D, respectively. A screw hole 14b is formed in the mounting surface 14a of the housing 14 (see fig. 2). The screw 70 passes through the through hole 74c and the groove 72d and engages with the screw hole 14b. The spacers 72A to 72D may have vertically elongated holes instead of the grooves 72D. The spacers 72A to 72D each include an operating lever 72e for elastically displacing the spacer itself along the mounting surface 14a.

As shown in fig. 9 and 13B, the operating lever 72e is positioned in front of the adjustment portions 74A to 74D. The adjustment portions 74A to 74D are provided with guide rail portions 74D, respectively. The guide rail portion 74d guides the operating lever 72e in the up-down direction. The spacers 72A to 72D are easily displaced up and down by the operating rod 72e.

The adjustment portions 74A to 74D are provided with projecting markers 74e, respectively. The indicator 74e indicates the center of the displacement range of each of the spacers 72A to 72D. When the operating rod 72E is adjacent to the marker 74E, the spacers 72A to 72E are positioned at the center of their displacement ranges. The user can easily know the amount of displacement that can be generated by the spacers 72A to 72E by the marker 74E.

Fig. 14 is a diagram for explaining a method of adjusting the distance between the operation unit 20 and the housing by using the spacer.

As shown in fig. 14, the operation unit 20 (unit main body 42) is temporarily fixed to the attachment surface 14a of the housing 14. Specifically, the spacers 72A to 72D are temporarily fixed to the housing 14 so that the operation unit 20 can be displaced in the vertical direction as indicated by the outlined arrow AR via the screw 70.

As described above, the adjustment portions 74A to 74D each include the follower surface 74A that contacts the cam surface 72b. When any of spacers 72A to 72D is displaced along mounting surface 14A, any of adjustment portions 74A to 74D is displaced perpendicularly to mounting surface 14A, that is, in the front-rear direction of heating cooker 10.

Thereby, the distances between the adjustment portions 74A to 74D and the mounting surface 14A are adjusted. That is, the distances between the portions in the outer peripheral edge of the exterior plate 47 and the mounting surface 14a are adjusted. As a result, the inclination of the operation unit 20 (the exterior plate 47) with respect to the housing 14 is adjusted.

After the inclination of the operation unit 20 with respect to the housing 14 is adjusted, the operation unit 20 is fixed to the housing 14 at the adjusted inclination by further tightening the screw 70.

The partitions 72A to 72D allow a height difference to be easily eliminated between the exterior panel 47 attached to the operation unit 20 and the grill door 32 of the grill chamber 30.

As described above, according to the present embodiment, the positioning accuracy of the upper end portion of the opening/closing panel 44 with respect to the unit main body 42 can be improved.

The present disclosure is not limited to the above-described embodiments. In the above-described embodiment, the opening/closing panel 44 is provided in the operation unit 20. However, the unit including the opening/closing panel may be an opening/closing unit for opening and closing a space in the case so as to be able to enter, for example.

In the above-described embodiment, as shown in fig. 8A and 8B, the push latch mechanism 58 is a clip-type push latch mechanism including a lock pin 60 and a latch 62. However, the push latch mechanism may also be of a magnetic type.

In the above embodiment, the unit main body 42 of the operation unit 20 and the housing 14 are formed of separate members. However, the unit main body and the housing may be integrally formed.

The present disclosure can be applied to a heating cooker provided with an opening/closing panel.
