Japanese Patent Application Publication No. 2006-38296

Drawer doors will look bad if they don't line up perfectly with the edges of the main body opening. Furthermore, if the opening of the heating chamber is not properly sealed, the heating efficiency will decrease. In the cooking device of Patent Document 1, the drawer door also serves as a lid of the heating chamber. If the relative positions of the main body and the heating chamber are misaligned, either the opening of the main body or the opening of the heating chamber will not fit perfectly with the door. The present specification relates to a heating cooker that has a door on the front and a heating chamber inside, and provides a technique that can appropriately close both the opening of the main body and the opening of the heating chamber.

The heating cooker disclosed in this specification includes a main body, a drawer, a heating chamber, and a lid. The body has a first opening in its front face. The drawer is supported by the main body so as to be movable back and forth. The drawer has a door that closes the first opening at a rear end position of the movement range. The heating chamber has a second opening on the top surface. The heating chamber is supported by the drawer and is housed within the main body when the drawer is in the rear end position. The lid can close the second opening with the drawer in the rear end position. The lid is supported by the main body so as to be movable in the vertical direction. In the heating cooker disclosed in this specification , the heating chamber is supported by the drawer so as to be movable in the front-rear direction or the left-right direction.

By employing the above-described structure, the heating cooker disclosed in this specification allows one of the lid and the heating chamber to move relative to the other while the door closes the first opening of the main body. be able to. That is, the lid can be aligned with the second opening independently of the door. The door can appropriately close the first opening of the main body, and the lid can appropriately close the second opening of the heating chamber.

The heating cooker disclosed in this specification preferably includes a guide mechanism that gradually restricts the relative position of the lid and the heating chamber in the front-rear direction or left-right direction as the lid descends. In this case, instead of the heating chamber, a lid may be supported by the main body so as to be movable in the front-back direction or the left-right direction. Although details will be described in the examples, the guide mechanism may be a tapered portion provided on the edge of the lid (or the edge of the side wall of the heating chamber surrounding the first opening), or may be a tapered portion provided on one of the lid and the heating chamber. It may be a pin provided on the other side and a fitting hole provided on the other side. For example, the fitting hole provided in the heating chamber is tapered, and the pin on the lid is inserted into the fitting hole in the heating chamber, and as the lid is lowered, the position of the pin (i.e. the lid) in the front, back, left and right is gradually regulated. be done. By providing the guide mechanism, the lid can accurately seal the second opening.

The heating cooker disclosed in this specification may further include a link mechanism that lowers the lid in conjunction with the retreat of the drawer. The lid can reliably close the second opening without providing an actuator.

The heating cooker disclosed in this specification may include a retracting mechanism for retracting the drawer to the rear end position. The retracting mechanism can prevent both the door and the lid from being half-open. The retraction mechanism pulls the drawer to the rear end position when the drawer approaches the rear end position by a predetermined distance or less. An example of a retraction mechanism is as follows. The main body includes a fixed rail extending in the front-rear direction, and the drawer includes a movable rail that slides along the fixed rail. At the rear end of the fixed rail, the upper surface of the rail and the rear surface of the rail are connected by a curved surface. At the rear end of the movable rail, there is provided a lever that extends rearward and whose tip rotates toward the fixed rail when viewed from the side, and the lever is biased so that its tip is pressed against the fixed rail. . The tip of the lever is in contact with the top surface of the fixed rail. When the tip of the lever reaches the curved surface of the fixed rail, the lever swings along the curved surface due to the biasing force and the base of the lever is pulled rearward. That is, the drawer is pulled back.

Details and further improvements of the technology disclosed in this specification will be explained in the following "Detailed Description of the Invention".

FIG. 3 is a cross-sectional view showing the relative positional relationship between the heating chamber and the lid. It is a side view of a retraction mechanism. It is a side view which shows the modification of a link mechanism. It is a sectional view showing a modification of a guide mechanism.

A cooking device 2 according to an embodiment will be described with reference to the drawings. FIG. 1 shows a perspective view of the cooking device 2. As shown in FIG. The heating cooker 2 includes a cabinet 10 in which a stove unit 3 is incorporated in the upper part, a drawer 20 supported by the cabinet 10, a heating chamber 30 supported (stored) in the drawer 20, and a lid. It is equipped with 40. An opening 11 is provided in the front surface of the cabinet 10, and the drawer 20 is accommodated in the cabinet 10 through the opening 11. The drawer 20 is supported by the cabinet 10 so as to be movable in the front-back direction. A door 21 is provided at the front of the drawer 20. The door 21 closes the opening 11 when the drawer 20 is located at the rear end position of the range of movement in the front-rear direction. That is, the rear end position means a position where the drawer 20 is completely stored in the cabinet 10 and the door 21 closes the opening 11.

The stove unit 3 includes three stove burners at the top and a grill storage inside.

A rail (movable rail 22) is provided on the side surface of the drawer 20, and a fixed rail that engages with the movable rail 22 is provided in the cabinet 10. In Figure 1, the fixed rails are hidden and cannot be seen. By sliding the movable rail 22 along the fixed rail, the drawer 20 smoothly moves back and forth.

The heating chamber 30 is housed in the drawer 20. Inside the cabinet 10, a partition plate 12 is provided which divides the space in which the drawers 20 are accommodated into left and right halves. The heating chamber 30 is accommodated in one space partitioned by the partition plate 12. The heating chamber 30 has an opening 31 on the top surface. The heating chamber 30 is a microwave oven and is equipped with a magnetron, etc., but in FIG. 1 (and subsequent figures), the heating chamber 30 is simplified and shown as a simple box.

The drawer 20 is pulled out from the cabinet 10 and food is placed into the heating chamber 30 through the opening 31. When the drawer 20 is closed, the lid 40 automatically lowers and closes the opening 31. When the user operates a switch (not shown), heating of the food in the heating chamber 30 is started.

In the cooking device 2 of the embodiment, a door 21 that closes the opening 11 of the cabinet 10 and a lid 40 that closes the opening 31 of the heating chamber 30 are independent. Therefore, even if the positions of the drawer 20 and the heating chamber 30 are misaligned, the door 21 can appropriately close the opening 11, and the lid 40 can reliably seal the opening 31. A structure in which the lid 40 reliably seals the opening 31 will be described below.

A lid 40 that closes the opening 31 of the heating chamber 30 is supported by the cabinet 10 so as to be movable in the vertical direction. The lid 40 descends in conjunction with the retreat of the drawer 20. The lid 40 seals the opening 31 of the heating chamber 30 with the drawer 20 located at the rear end position. The lid 40 moves up as the drawer 20 moves forward from the rear end position.

A guide groove 32 is provided on the side surface of the heating chamber 30, and this guide groove 32 is involved in interlocking the lid 40. FIG. 2 shows a link mechanism 50 that lowers the lid 40 in conjunction with the withdrawal of the drawer 20. FIG. 2 corresponds to a side view of the heating chamber 30. The link mechanism 50 includes a guide groove 32 provided on the side surface of the heating chamber 30 and a link 51 supported by the partition plate 12 of the cabinet 10. In FIG. 2, only a portion of the cabinet 10 and the drawer 20 are shown. Further, the partition plate 12 is shown with imaginary lines. A mechanism similar to the link mechanism 50 shown in FIG. 2 is also provided on the opposite side of the heating chamber 30.

Fig. 2(A) shows the drawer 20 (heating chamber 30) located forward of the rear end position, and Fig. 2(B) shows the drawer 20 (heating chamber 30) located at the rear end position. It shows the state in which In FIG. 2(B), the door 21 of the drawer 20 closes the opening 11 of the cabinet 10.

The lid 40 is supported by two links 51. The two links 51 are arranged in the front-rear direction, and the front link 51 is referred to as a front link 51a, and the rear link 51 is referred to as a rear link 51b. When the front link 51a and the rear link 51b are expressed without distinction, they are written as link 51.

A rotating shaft 52 is provided on the partition plate 12, and the lower end of the link 51 is supported by the rotating shaft 52. The link 51 is swingable about the rotating shaft 52 as a fulcrum. A rotating shaft 53 is provided on the side surface of the lid 40, and the upper end of the link 51 is supported by the rotating shaft 53. Note that in the rear link 51b, the rotating shaft 53 is fixed to the lid 40 via a stay 55. The link 51 is swingable about the rotating shaft 53 as a fulcrum. As shown in FIG. 2, the two links 51 (front link 51a and rear link 51b) constitute a parallel link, and when the link 51 swings, the lid 40 moves up and down while remaining horizontal. . The lid 40 is supported by the cabinet 10 via the partition plate 12 and the link 51 so as to be movable in the vertical direction.

The guide groove 32 is a space sandwiched between an upper guide rail 32a and a lower guide rail 32b. Further, the rear end of the lower guide rail 32b is an inclined rail 32c that becomes higher toward the rear. A protrusion 54 is provided on the side of the link 51 facing the heating chamber 30, and the protrusion 54 is engaged with a guide groove 32 provided on the side surface of the heating chamber 30. The width of the projection 54 in the vertical direction is equal to the width of the guide groove 32 in the vertical direction. The link 51 is restrained by the guide groove 32.

The guide groove 32 is high in the central part of the heating chamber 30 and shifted downward in the front part. As can be understood by comparing FIGS. 2(A) and 2(B), when the heating chamber 30 (drawer 20) is located in front of the rear end position, the protrusion 54 of the front link 51a is in the longitudinal direction of the guide groove 32. is restrained at a relatively high position in the central part of the Since the front link 51a and the rear link 51b constitute a parallel link, the rear link 51b is inclined at the same angle as the front link 51a. As a result, the lid 40 is located above the heating chamber 30 and separated from the opening 31.

When the drawer 20 (heating chamber 30) retreats to the rear end position, the protrusion 54 of the front link 51a is guided by the guide groove 32 and moves to a relatively low position at the front. The downward movement of the protrusion 54 causes the front link 51a to rotate clockwise as indicated by the thick arrow line a in FIG. 2(B), thereby moving the rotating shaft 53 downward. In conjunction with the clockwise rotation of the front link 51a, the rear link 51b also rotates clockwise (see thick arrow line b in FIG. 2(B)), and the rotation shaft 53 of the rear link 51b also moves downward. As a result, as indicated by the thick arrow c in FIG. 2(B), the lid 40a that has been spaced apart from the opening 31 is lowered to close the opening 31 of the heating chamber 30. The protrusion 54 of the rear link 51b contacts the lower surface of the inclined rail 32c following the rear end of the lower guide rail 32b, and is pressed downward as the inclined rail 32c moves rearward. The protrusion 54 of the front link 51a contacts the lower surface of the upper guide rail 32a, and is pressed downward by the lower surface of the upper guide rail 32a when the heating chamber 30 is located at the rear end position. The lid 40 is pressed against the upper surface of the side wall of the heating chamber around the opening 31 by the pressure applied thereto.

In this way, the lid 40 is lowered by the link mechanism 50 as the drawer 20 retreats, and closes the opening 31 of the heating chamber 30 when the drawer 20 is located at the rear end position. When the drawer 20 moves forward, the link mechanism 50 raises the lid 40 and opens the opening 31. Note that the link mechanism 50 shown in FIG. 2 is an example. The link mechanism that lowers the lid 40 in conjunction with the retreat of the drawer 20 and closes the opening 31 at the rear end position may be realized by a structure other than the link mechanism 50 of FIG. 2.

Although not shown in FIG. 2, the heating chamber 30 is supported so as to be movable back and forth and left and right with respect to the drawer 20, and as the lid 40 descends, its relative position with respect to the heating chamber 30 in the front, back, left and right directions is gradually restricted. It is equipped with a guide mechanism to FIG. 3 shows a sectional view of the heating chamber 30 and the lid 40. FIG. 3 shows the relative positional relationship between the heating chamber 30 and the lid 40 in the front-rear direction. FIG. 3(A) shows a state in which the lid 40 is raised and separated from the opening 31. FIG. 3(B) shows a state in which the lid 40 closes the opening 31. As mentioned above, the lid 40 closes the opening 31 of the heating chamber 30 when the drawer 20 is located at the rear end position, but in FIG. 3(A), for convenience, the drawer 20 is retracted to the rear end position. The lid 40 is depicted above the heating chamber 30 with the door 21 tightly closing the opening 11 of the cabinet 10.

The heating chamber 30 is provided with a ball 38 on the lower surface, and the lower end of the ball 38 is in contact with the floor surface of the drawer 20 and is supported by the drawer 20. The heating chamber 30 is movable back and forth, left and right within a small range (for example, 2 cm) with respect to the floor surface of the drawer 20. In addition, as a movable means, the ball 38 may be provided on the side surface instead of the bottom surface. Further, as the movable means, something other than the ball 38, for example, a swinging means such as a spring may be used.

As explained in FIG. 2, the lid 40 is supported by the cabinet 10 so as to be movable in the vertical direction. A top surface 34 of a side wall 33 of the heating chamber 30 surrounds the opening 31 . A protruding line 41 is provided on the lower surface of the lid 40 so as to go around the opening 31, and an outer circumferential surface 42 of the protruding line 41 is inclined. The outer circumferential surface 42 is inclined so as to be further away from the edge of the lid 40 as it goes downward.

In the state shown in FIG. 3(A), the heating chamber 30 is displaced backward with respect to the lid 40. As described above, FIG. 3A shows a state in which the drawer 20 is located at the rear end position, but the lid 40 is moved upward for convenience. When the lid 40 is lowered, the outer circumferential surface 42 of the protruding strip 41 comes into contact with the inner edge 34a of the upper surface 34 of the side wall 33 of the heating chamber 30. Since the heating chamber 30 can move forward, backward, left and right with respect to the drawer 20, the heating chamber 30 pushed by the outer peripheral surface 42 moves forward. As the lid 40 further descends and the point of contact with the inner edge 34a approaches the base 42a of the outer circumferential surface 42, the relative positions of the heating chamber 30 and the lid 40 in the front-rear and left-right directions are adjusted to correct positions. That is, as the lid 40 descends, the relative positions of the lid 40 and the heating chamber 30 in the front-rear and left-right directions are gradually regulated. The protruding strip 41 having an outer circumferential surface 42 that slopes away from the edge of the lid 40 toward the lower end corresponds to the guide mechanism described above.

When the heating chamber 30 and the lid 40 are viewed from above, the outline drawn by the base 42a of the outer peripheral surface 42 of the protruding strip 41 going around the opening 31 is the same as the outline drawn by the inner edge 34a of the upper surface 34 of the side wall 33 going around the opening 31. It has a similar shape to the contour line. Therefore, as shown in FIG. 3(B), when the lid 40 is lowered to the height of the upper surface 34 of the heating chamber 30, the relative position of the lid 40 and the heating chamber 30 is accurately determined. A protruding strip 35 that goes around the opening 31 is provided on the inner surface of the heating chamber 30 (inner surface of the side wall 33), and a sealing material 39 is arranged on the upper surface of the protruding strip 35. When the lid 40 is lowered to the correct position, the side wall 33 and the lid 40 are sealed by the sealing material 39. That is, the sealing material 39 seals the opening 31 and seals the internal space of the heating chamber 30 .

As described with reference to FIG. 2, the lid 40 closes the opening 31 while being pressurized downward by the link mechanism 50. Due to the pressure applied by the link mechanism 50, the sealing material 39 is pressurized from above and below, and the lid 40 appropriately seals the opening 31. The heating chamber 30 is movable back and forth and left and right with respect to the drawer 20. With the door 21 of the drawer 20 properly closing the opening 11 of the cabinet 10, the heating chamber 30 moves to match the position of the lid 40. It is possible for the door 21 to appropriately close the opening 11 and for the lid 40 to seal the opening 31 of the heating chamber 30 at the same time.

As will be described later, the lid 40 may be supported by the cabinet 10 so as to be movable back and forth and left and right. However, it is preferable that the heating chamber 30 be supported by the drawer 20 so as to be movable back and forth and left and right. If the heating chamber 30 is fixed to the drawer 20, there is a risk that the drawer 20 will move when a horizontal force is applied to the heating chamber 30 from the lid 40. If the heating chamber 30 is movably supported relative to the drawer 20, the drawer 20 will not move even if the heating chamber 30 moves, and the door 21 can maintain the state in which the opening 11 is closed.

The heating cooker 2 includes a retracting mechanism that pulls the drawer 20 to the rear end position when the drawer 20 is retracted to a certain position. FIG. 4 shows a side view of the retraction mechanism 60. As shown in FIG. 1, a rail (movable rail 22) is provided on the side surface of the drawer 20. A fixed rail 61 is provided in the cabinet 10 (not shown in FIG. 4) so as to be located below the movable rail 22. As the movable rail 22 slides on the fixed rail 61, the drawer 20 can be smoothly moved in the front-rear direction with respect to the cabinet 10.

Although the cabinet 10 is not shown in FIG. 4, the cabinet 10 is provided with a stopper 66 for regulating the rear end position of the movable rail 22 (ie, the drawer 20). The stopper 66 is located at the rear of the movable rail 22. The position of the movable rail 22 (drawer 20) when the rear end of the movable rail 22 contacts the stopper 66 corresponds to the rear end position of the movable rail 22 (drawer 20).

The upper surface and rear surface of the fixed rail 61 are connected by a curved surface 62. The curved surface 62 starts a distance dL from the rear end position (position of the stopper 66) in front.

A lever 63 is attached to the rear end of the movable rail 22. The lever 63 is supported by the movable rail 22 so that its tip 63a (the rear tip of the lever 63) swings in the vertical direction. A tip 63a of the lever 63 swings up and down about a rotating shaft 64 at the rear end of the movable rail 22. A spring 65 is attached to the rear end of the movable rail 22 to bias the lever 63 so as to lower the tip 63a of the lever 63. In other words, the lever 63 is swingably attached to the movable rail 22 so that the tip 63a moves toward the fixed rail 61.

FIG. 4(A) shows a state in which the tip 63a of the lever 63 is located further forward than the distance dL from the rear end position. In other words, the tip 63a of the lever 63 is located forward of the curved surface 62. In this state, the drawer 20 does not move unless the user pushes the drawer 20.

FIG. 4B shows a state in which the tip 63a of the lever 63 is closer to the rear end position than the distance dL. In other words, FIG. 4(B) shows a state in which the tip 63a of the lever 63 has reached the curved surface 62. The lever 63 is biased by a spring 65 to lower the tip 63a. Due to this biasing force, the lever 63 swings so that the tip 63a is lowered, as indicated by the arrow line a in FIG. 4(B), and as a result, the movable rail 22 (drawer 20) is pulled rearward.

FIG. 4(C) shows a state in which the lever 63 has further swung downward as indicated by arrow b, and the rear end of the movable rail 22 has come into contact with the stopper 66. FIG. 4(C) corresponds to a state in which the drawer 20 is located at the rear end position. Due to the biasing force of the spring 65, the drawer 20 is drawn to the rear end position and held in the drawn state.

By providing the retracting mechanism 60, the drawer 20 is reliably held at the rear end position. That is, the door 21 reliably closes the opening 11, and the lid 40, which descends in conjunction with the retreat of the drawer 20, reliably seals the opening 31 of the heating chamber 30.

Note that the position where the stopper 66 is provided is not limited to the rear of the movable rail 22. The door 21 of the drawer 20 abuts against the side wall around the opening 11 of the cabinet 10, and does not retreat any further after the opening 11 is closed. That is, the side wall around the opening 11 serves as the stopper 66. Although the stopper 66 is illustrated in FIG. 4 to aid understanding, the stopper 66 at the rear of the movable rail 22 may not be provided since the side wall around the opening 11 plays the role of a stopper.

A cooking device 2a having a link mechanism 150 according to a modified example will be described with reference to FIG. FIG. 5 shows a side view of the heating chamber 30 and corresponds to FIG. 2(B). In the link mechanism 150, the link 151 is provided with a horizontally elongated hole 56. A rotating shaft 53 of the lid 40 is locked in a long hole 56. Therefore, the lid 40 is movable back and forth relative to the link 151. In the cooking device 2a, the heating chamber 30 is fixed to the drawer 20, and the lid 40 is movable back and forth with respect to the cabinet 10 (link 151). The lid 40 and the heating chamber 30 are relatively movable back and forth. The lid 40 is lowered in conjunction with the drawer 20 retreating. The position of the lid 40 is adjusted back and forth to match the opening 31 of the heating chamber 30.

A predetermined gap may be provided between the side surface of the lid 40 and the link 151. By securing the gap, the lid 40 can be moved in the left-right direction relative to the link 151 (that is, relative to the cabinet 10). Even if the heating chamber 30 is fixed to the drawer 20, the lid 40 can be moved back and forth and left and right with respect to the cabinet 10. With such a structure, the door 21 can appropriately close the opening 11, and the lid 40 can appropriately seal the opening 31 of the heating chamber 30.

Several modified examples of the guide mechanism that gradually restricts the relative positions of the lid 40 and the heating chamber 30 in the front-rear direction or left-right direction as the lid 40 descends will be described. FIG. 6(A) is a sectional view of a first modified example of the guide mechanism.

The opening 31 of the heating chamber 30 is surrounded by the upper surface 234 of the side wall 233. The guide mechanism of the first modification includes an inclined upper surface 234c provided inside the upper surface 234 and a protrusion 241 provided on the lid 40. The inclined upper surface 234c is a part of the upper surface 234 of the side wall 233. The inclined upper surface 234c is inclined so that the outer edge 234b side of the upper surface 234 is higher and the inner edge 234a side is lower. A protrusion 241 is provided on the lower surface of the lid 40 and extends around the opening 31. The tip of the protrusion 241 is curved. When the lid 40 is lowered, the tips of the protrusions 241 come into contact with the inclined upper surface 234c. Even if the lid 40 and the heating chamber 30 are misaligned in the front, rear, left and right directions, as the lid 40 descends, the protrusion 241 (that is, the lid 40) shifts in the horizontal direction along the slope of the inclined upper surface 234c. That is, as the lid 40 descends, the relative positions of the lid 40 and the heating chamber 30 in the front, rear, left and right directions are gradually regulated. The sealing material 39 is arranged so as to be sandwiched between the inclined upper surface 234c and the protruding strip 241. The sealing material 39 goes around the opening 31. The lid 40 reliably seals the opening 31 of the heating chamber 30 by sandwiching the sealing material 39 surrounding the opening 31 between the inclined upper surface 234c and the protrusion 241.

FIG. 6(B) is a sectional view of a second modified example of the guide mechanism. The opening 31 of the heating chamber 30 is surrounded by the upper surface 334 of the side wall 333. The guide mechanism of the second modification includes an inclined upper surface 334c provided on the outside of the upper surface 334, and a protrusion 341 provided on the lid 40. The inclined upper surface 334c is a part of the upper surface 334 of the side wall 333. The inclined upper surface 334c is inclined such that the outer edge 334b side of the upper surface 334 is lower and the inner edge 334a side is higher. A protruding strip 341 that goes around the opening 31 is provided on the lower surface of the lid 40 . When the lid 40 is lowered, the tips of the protrusions 341 come into contact with the inclined upper surface 334c. Even if the lid 40 and the heating chamber 30 are misaligned in the front, rear, left and right directions, as the lid 40 descends, the protrusion 341 (that is, the lid 40) shifts in the horizontal direction along the slope of the inclined upper surface 334c. That is, as the lid 40 descends, the relative positions of the lid 40 and the heating chamber 30 in the front, rear, left and right directions are gradually regulated. A sealing material 39 is arranged so as to be sandwiched between the upper surface 334 and the lower surface of the lid 40. The sealing material 39 goes around the opening 31. The sealing material 39 surrounding the opening 31 is sandwiched between the top surface 334 and the lid 40, so that the lid 40 reliably seals the opening 31 of the heating chamber 30.

FIG. 6(C) is a sectional view of a third modification of the guide mechanism. The guide mechanism of the third modification includes a protrusion provided on the upper surface 434 of the side wall 433 of the heating chamber 30 (chamber side protrusion 435) and a protrusion provided on the lid 40 (lid side protrusion 441). be done.

The chamber side protrusion 435 is provided on the inner edge 434a side of the upper surface 434 and goes around the opening 31. The lid side protrusion 441 is provided so as to face the upper surface 434 of the side wall 433 and goes around the opening 31. The inner circumferential side of the lid side protrusion 441 forms an inclined inner circumferential surface 442 . The inclined inner circumferential surface 442 is inclined so that the base side approaches the center of the lid 40.

When the lid 40 is lowered, the tip of the chamber-side protrusion 435 comes into contact with the inclined inner circumferential surface 442 of the lid-side protrusion 441. Even if the lid 40 and the heating chamber 30 are misaligned in the front, rear, left and right directions, as the lid 40 descends, the inclined inner circumferential surface 442 (that is, the lid 40) comes into contact with the tip of the chamber side ridge 435 and shifts in the horizontal direction. That is, as the lid 40 descends, the relative positions of the lid 40 and the heating chamber 30 in the front, rear, left and right directions are gradually regulated. The sealing material 39 is arranged so as to be sandwiched between the upper surface 434 of the side wall 433 and the upper surface of the lid side protrusion 441. The sealing material 39 goes around the opening 31. The sealing material 39 surrounding the opening 31 is sandwiched between the upper surface 434 of the side wall 433 and the upper surface of the lid-side protrusion 441, so that the lid 40 reliably seals the opening 31 of the heating chamber 30.

FIG. 6(D) is a sectional view of a fourth modification of the guide mechanism. The guide mechanism of the fourth modification includes a tapered hole 535 provided on the upper surface 534 of the side wall 533 of the heating chamber 30 and a pin 541 provided on the lid 40.

The tapered hole 535 has a wide opening on the upper surface 534 and tapers toward the back of the hole. In the deep portion 535a of the tapered hole 535, the diameter of the hole is constant. The pin 541 of the lid 40 is provided to face the tapered hole 535. The outer diameter of the pin 541 is approximately the same as the diameter of the deep portion 535a of the tapered hole 535. When the lid 40 is lowered, the tip of the pin 541 comes into contact with the inner surface of the tapered hole 535. The pin 541 (lid 40) moves along the inclined inner surface of the tapered hole 535 and is finally aligned with the deep portion 535a.

A sealing material 39 is arranged on the upper surface 534 of the side wall 533 so as to surround the opening 31 . When the lid 40 is lowered to the upper surface 534, the sealing material 39 is sandwiched between the upper surface 534 and the lower surface of the lid 40, and the lid 40 reliably seals the opening 31 of the heating chamber 30.

A plurality of tapered holes 535 are provided in the side wall 533, and a plurality of pins 541 are provided in the lid 40 so as to correspond to each tapered hole 535. For example, two tapered holes 535 are provided at diagonal positions on the upper surface 534 surrounding the opening 31 when viewed from above.

Alternatively, the tapered hole 535 may be a groove provided in the upper surface 534 of the side wall 533 so as to go around the opening 31. In that case, the pin 541 may be a protruding strip provided on the lower surface of the lid 40 so as to go around the opening 31.

Points to note regarding the techniques described in the examples will be described. In the embodiment, it is desirable that the heating chamber 30 and the lid 40 are relatively movable in the front, back, left and right directions. If the heating chamber 30 and the lid 40 are relatively movable in the front-rear direction or the left-right direction, the lid 40 can properly seal the opening 31 at least in the movable direction.

The heating chamber 30 may be a microwave oven or a cooking device equipped with an electric or gas heater. The cabinet 10 may be for a system kitchen, a tabletop type, or a wall-in type.

The cabinet 10 of the embodiment corresponds to an example of the main body of the cooking device 2, and the opening 11 corresponds to an example of the first opening. The opening 31 of the heating chamber 30 corresponds to an example of the second opening.
