  FIG. 4 is a perspective view of the cooking chamber 14 as viewed from the back side surface 14a. An opening A14b is provided on the left back side of the cooking chamber 14 (near symbol B in FIG. 4), and the right back side (reference symbol in FIG. 4). In the vicinity of C), an opening B14c is provided. The opening A14b is provided with a heater holding metal 19a that seals the opening A14b and is rotatable about the hinge pin 37a held by the support 20a. The opening B14c is provided with a heater holding bracket 19b that seals the opening B14c and is rotatable about the hinge pin 37b held by the support 20b. Thus, since the heater holding metal fittings 19a and 19b are made rotatable, the lower heater 43 fixed to these via the heater metal fittings 17a and 17b can be moved up and down. In the present embodiment, when the user moves the lower heater 43, the operation lever 24 protruding from the front surface of the main body 2 is used. The details will be described later.

  Next, the configuration in the vicinity of both openings will be described in more detail with reference to FIGS.

  First, the configuration in the vicinity of the opening A14b, indicated by the symbol B in FIG. 4, will be described with reference to FIGS. As shown in FIG. 6, a terminal portion 43a of the lower heater 43 projects from the rear side of the cooking chamber 43, and a terminal 43b is provided at the tip thereof. The lower heater 43 is heated by electric power supplied to the terminal 43b from a power source (not shown) via an electric wire. As shown in FIG. 7, the terminal portion 43a of the lower heater 43 is supported by the support portion 17a-1 of the heater metal fitting 17a and is fixed by crimping with the heater fixing portion 17a-2. Thus, by supporting the terminal portion 43a at two points, the lower heater 43 can be firmly fixed, and the occurrence of play in the heater fixing portion 17a-2 due to the weight of the lower heater 43 can be suppressed.

  Moreover, as shown in FIG. 6, the heater holding | maintenance metal fitting 19a is provided with the plane part 19a-1, the hinge part 19a-2, the penetration part 19a-3, the connection part 19a-4, and the electric wire fixing | fixed part 19a-5. Of these, the flat surface portion 19a-1 has a function of closing the opening A14b and a function of fixing the lower heater 43 through the heater fitting 17a. When cooking is performed, the opening A14b is closed by the flat portion 19a-1, so that leakage of oil smoke and the like generated during cooking from the opening A14b is suppressed. The heater fitting 17a to which the lower heater 43 is fixed is fixed to the heater holding fitting 19a with screws or the like. At this time, the heater metal member 17a may be directly fixed to the flat portion 19a-1 of the heater holding metal member 19a, or may be indirectly fixed through a plurality of components.

  The hinge part 19a-2 is arranged so that a flange perpendicular to the plane part 19a-1 is formed in a substantially U shape, and the through part 19a-3 provided on the flange of the hinge part 19a-2 is: This is for penetrating the hinge pin 37a.

  The connecting portion 19a-4 transmits a force from an arm 23, which will be described later, to the heater holding metal 19a. When the arm 23 connected to the connecting portion 19a-4 moves in the forward direction, the hinge pin 37a serves as a fulcrum. The holding metal fitting 19a falls to the back side, and the lower heater 43 fixed thereto is lifted.

  The electric wire fixing portion 19a-5 is for holding and fixing the electric wire connected to the terminal 43b. When the operation lever 24 is operated and the lower heater 43 is lifted, the wire fixing portion 19a-5 fluctuates while maintaining the positional relationship with the terminal 43b, so that the force acting on the wire is applied to the wire fixing portion 19a-5. Thus, no stress is generated on the terminal 43b. For this reason, in the terminal 43b, the disconnection of the electric wire by stress can be avoided.

  The support tool 20a is fixed to the bottom surface of the cooking cabinet 14, and includes a hinge part 20a-1 and a penetration part 20a-2. Among these, the hinge part 20a-1 arrange | positions the flange perpendicular | vertical to the back side surface 14a of the cooking chamber 14 so that a substantially U-shape may be formed, and the penetration part 20a- provided in the hinge part 20a-1 2 is for penetrating the hinge pin 37a.

  As described above, the hinge 31a is formed by the heater holding bracket 19a, the hinge pin 37a, and the support 20a, and the lower heater 43 can be lifted freely with the hinge pin 37a as an axis. As shown in FIG. 2, the heater holding metal 19 a and the main body 2 are connected by a conductive member 50. Thereby, the exterior of the lower heater 43 can be reliably connected to the ground without depending on the connection via the hinge 31a.

  Next, the configuration in the vicinity of the opening B14c indicated by reference numeral C in FIG. 4 will be described with reference to FIGS. As shown in FIG. 7, the right rear side of the lower heater 43 is supported by the support portion 17b-1 of the heater metal member 17b. Since the lower heater 43 is supported by the two heater brackets 17a and 17b, the lower heater 43 can be firmly fixed, and play due to the weight of the lower heater 43 can be suppressed.

  Further, as shown in FIG. 5, the heater holding metal 19b includes a flat surface portion 19b-1, a hinge portion 19b-2, and a through portion 19b-3. Among these, the plane portion 19a-1 has a function of closing the opening B14c and a function of fixing the lower heater 43 through the heater metal fitting 17b. When cooking, the opening B14c is closed by the flat portion 19b-1, so that leakage of oil smoke and the like generated during cooking from the opening B14c is suppressed. The heater metal fitting 17b to which the lower heater 43 is fixed is fixed to the heater holding metal fitting 19b with screws or the like. At this time, the heater metal member 17b may be directly fixed to the flat portion 19b-1 of the heater holding metal member 19b, or may be indirectly fixed through a plurality of components.

  The hinge portion 19b-2 has a flange perpendicular to the flat surface portion 19b-1 arranged so as to form a substantially U-shape. The through portion 19b-3 provided on the flange of the hinge portion 19b-2 has a hinge pin. It is for penetrating 37b.

  The support tool 20b is fixed to the back side surface 14a of the cooking cabinet 14, and includes a hinge part 20b-1 and a penetration part 20b-2. Among these, the hinge part 20b-1 arrange | positions a flange perpendicular | vertical to the back side surface 14a of the cooking chamber 14 so that a substantially U-shape may be formed, and the penetration part 20b- provided in the hinge part 20b-1 2 is for penetrating the hinge pin 37b.

  As described above, the hinge 31b is formed by the heater holding bracket 19b, the hinge pin 37b, and the support 20b, and the lower heater 43 can be lifted freely with the hinge pin 37b as an axis.

  Next, a mechanism for operating the operation lever 24 and lifting the lower heater 43 will be described in detail. As shown in FIG. 2, the support tool 20 a is an integrally molded part provided so as to cover the lower part of the cooking chamber 14 from the front end to the rear end of the cooking chamber 14, and an operation lever attached to the upper surface thereof. 24, the movable space of the arm 23 is secured. In this embodiment, since the support 20a is integrally formed, variations can be suppressed, and it becomes easy to keep the mechanical quality of the lower heater driving mechanism described later uniform.

  As shown in FIG. 7, the operation lever 24 has a front end of the operation portion 24 a that passes through a lever guide 35 that is a guide groove provided in the flange portion 14 e on the lower side of the cooking chamber 14 and is formed on the front surface of the main body 2. The lever is a lever that moves left and right within the lever guide 35 with a screw 40 (a split pin or the like may be substituted) as a fulcrum 24b. The operation lever 24 is always urged upward by a spring 25 provided below. Next to the fulcrum 24b, an action point 24c is provided, and the operation part 24a, the fulcrum 24b, and the action point 24c constitute a substantially L-shaped insulator. The front end of the substantially I-shaped arm 23 is rotatably connected to the action point 24c, and the arm 23 can be moved by operating the operation lever 24. As is clear from FIG. 7, the distance from the operation portion 24a to the fulcrum 24b of the operation lever 24 is longer than the distance from the fulcrum 24b to the action point 24c, so that the user can move the arm 23 with a small force. . The operation lever 24, the screw 40, and the arm 23 described above constitute a power transmission mechanism that transmits the force applied by the user. If the operation lever 24 is made of a metal such as stainless steel, the operation lever 24 also becomes hot to some extent due to heat conduction when the inside of the cooking chamber 14 is hot. You can know the approximate temperature.

  Next, the configuration of the lever guide 35 will be described in detail with reference to FIG. The lever guide 35 is substantially U-shaped with the upper direction open, and a locking portion A35a is provided on the upper left, and a locking portion B35b is provided on the upper right. Further, a notch 35c is provided at the upper left of the locking portion B35b to securely hold the operation portion 24a, and a chamfer 35d is provided at the lower right of the locking portion A35a for smooth movement of the operation portion 24a. Is provided. Since the operation lever 24 is always urged upward by the spring 25, the operation portion 24a staying in one of the locking portions does not move unexpectedly to the other locking portion. When the upper surface of the spring 25 is slid while pushing down the operation portion 24a, it can be easily moved to the other locking portion.

  Next, a mechanism for operating the operation lever 24 to lift the lower heater 43 will be described. When cooking is possible, the lower heater 43 is placed on the heater receiver 22, and the operation portion 24 a of the operation lever 24 is positioned at the locking portion A 35 a of the lever guide 35. As shown in FIG. 7, when the user moves the locking portion B35b in the direction of the locking portion B35b (symbol A) while pushing down the operating portion 24a, the operation lever 24 rotates in the direction of the symbol B. Then, the rotational motion (symbol B) of the operation lever 24 is converted into a substantially linear motion (symbol C) in which the arm 23 moves forward. In this way, the force in the direction of the sign A is converted into a force in the direction of the sign C that is approximately 90 degrees different. When the rear end of the arm 23 connected to the connecting portion 19a-4 of the heater holding bracket 19a moves in the forward direction (reference symbol C), the heater holding bracket 19a falls to the back side with reference to the hinge pin 37a (reference symbol D). As a result, the lower heater 43 fixed to the heater holder 19a via the heater fitting 17a rotates in the direction of the reference sign E and lifts in the direction of the upper heater 42. With the rotation of the lower heater 43, the heater fitting 17b and the heater holding fitting 19b for fixing the lower heater 43 also rotate in the direction of the reference sign D with the hinge pin 37b as a fulcrum.

  Since the amount of movement of the arm 23 in the forward direction and the amount of lifting of the lower heater 43 are in a proportional relationship, in order to increase the amount of lifting of the lower heater 43, the amount of movement of the arm 23 in the forward direction may be increased. In the operation lever 24 of this embodiment, in order to maximize the amount of forward movement of the arm 23 when the operation unit 24a is moved, the operation unit 24a, the fulcrum 24b, and the action point 24c are arranged in a substantially isosceles triangle shape. Yes.

  When the lower heater 43 is lifted, a force in the direction opposite to that of the sign E is applied by the weight of the lower heater 43. As a result, a force in the opposite direction to the signs D, C, and B acts on each component, and finally a force (a leftward force) acts in the direction opposite to the sign A also on the operation unit 24a. As a result of the leftward force generated by the dead weight of the lower heater 43 and the upward force generated by the spring 25 acting, a leftward upward force acts on the operation portion 24a. A notch 35c is provided at the upper left of the locking part B35b, and the operation part 24a moved to the locking part B35b is securely held by the notch 35c. The state where the lower heater 43 is raised can be maintained without unexpectedly returning to the locking portion A35a.

  Next, the operation for returning the lifted lower heater 43 to the cooking position will be described in detail. When returning the lower heater 43 to the original position, the user moves the operating portion 24a to the right and removes it from the notch 35c, and then pushes it down to move it from the locking portion B35b to the locking portion A35a. At this time, the rotational movement of the operation lever 24 (reverse direction of symbol B) is converted into a substantially linear motion (reverse direction of symbol C) in which the arm 23 moves backward. When the arm 23 moves in the rearward direction, the heater holding bracket 19a rises to the front side with the hinge pin 37a as a fulcrum, and the lower heater 43 fixed thereto returns to a cooking position. As described above, since a leftward force is applied to the operation unit 24a, the operation unit 24a that is out of the notch 35c automatically moves to the left without applying any force. Further, since an upward force is applied to the operation unit 24a, the operation unit 24a moved to the left side of the lever guide 35 automatically moves upward and is locked without any force applied by the user. Fits in part A35a. And the heater holding | suppressing metal fitting 18 is mounted in the heater receptacle 22 provided in the side surface of the cooking chamber 14, and the lower heater 43 is fixed to the position at the time of cooking. As described above, the lower heater 43 can be returned to the cooking position.

  Next, the structure of the back surface of the oven door 12 of a present Example is demonstrated. On the back surface of the oven door 12, a recess or a hole is provided at a position corresponding to the locking portion A35a. Therefore, when the operation portion 24a of the operation lever 24 is in the locking portion A35a and the lower heater 43 is in a position where cooking is possible, the operation portion 24a fits into the recess or the hole, so that the oven door 12 can be closed. As a result of adopting such a configuration, the operation unit 24a is not erroneously operated during the oven cooking in which the oven door is closed. On the other hand, when the operation portion 24a is in the locking portion B35b and the lower heater 43 is lifted, the operation portion 24a collides with the back surface of the oven door 12, and thus the oven door 12 cannot be closed. For this reason, the user can confirm the state of the lower heater 43 only by confirming whether the oven door 12 is closed. A door switch that detects opening / closing of the oven door 12 may be provided so that the oven cooking does not start when the oven door 12 is open.

  Next, cooking using the heating cooker according to the present embodiment described above will be described by taking as an example a case where a fish is grilled as the object to be heated 30.

  First, when the oven door 12 is pulled forward, the slide rail 27 connected to the door receiver 26 is pulled out, and the oven plate 28 and the grill 29 are also pulled out together.

  When the oven door 12 is closed, the operation unit 24a is housed in the lower part of the oven door 12, so there is no worry of inadvertent touching or hooking clothes. In addition, when the oven door 12 is opened, the operation unit 24 a is located below the oven plate 28, so that it does not get in the way when the article 30 to be heated is placed on the grill 29.

  During cooking, oily smoke is generated from fish and the like, most of which is decomposed, purified and exhausted by a catalyst (not shown) mounted on the discharge outlet 41. However, a part adheres to the entire inner wall of the cooking chamber 14 as oil. When the number of times of cooking increases, the oil and fat adhering to the cooking chamber 14 melts and accumulates during cooking, and the bottom surface 14d of the cooking chamber 14 becomes particularly dirty.

  Next, a specific cleaning method for the bottom surface 14d of the cooking chamber 14 that has become dirty due to cooking will be described.

  First, in order to prevent burns during cleaning, after confirming that the cooking chamber 14 is cold, the oven door 12 is pulled out, the oven plate 28 and the grill net 29 are removed, and then the oven door 12 is removed. Thereby, since there is no obstacle in the opening 14d, the operation portion 24a of the operation lever 24 can be visually recognized and can be easily operated. When the operating portion 24a is pushed down and slid from the locking portion A35a of the lever guide 35 to the locking portion B35b, the lower heater 43 is lifted as shown in FIG. Thereby, since a space for putting a hand under the lower heater 43 is created, the bottom surface 14d of the cooking cabinet 14 can be easily wiped with a wet cloth or a cloth soaked with a neutral detergent. When cleaning is completed, the position of the lower heater 43 can be returned to the cooking position by returning the operating portion 24a of the operating lever 24 from the locking portion B35b to the locking portion A35a, and cooking can be performed again.

  According to the present embodiment described above, since the heater can be moved by the operation unit provided on the front side of the main body of the heating cooker, safety and usability can be improved.

  The cooking device of Example 2 will be described. Note that the description of the configuration equivalent to that of the first embodiment is omitted.

  In the cooking device of the present embodiment, a shutter having a hole penetrating the operation portion 24a of the operation lever 24 is provided on the back side of the flange portion 14e shown in FIG. 9 so that the inside of the lever guide 35 cannot be seen. Is. In this embodiment, the width of the shutter is at least twice that of the lever guide 35, the height is at least one time that of the lever guide 35, the position of the through hole is substantially the center, and the size of the through hole is the size of the operation portion 24a. The size did not hinder vertical movement. As the operation portion 24a moves, a shutter having a width more than twice that of the lever guide 35 slides, so that the inside cannot be seen through the lever guide 35 regardless of the engagement portion of the operation portion 24a. You can

  The heating cooker of Example 3 will be described. Note that the description of the configuration equivalent to that of the first embodiment is omitted.

  In the first embodiment, the configuration in which the lower heater 43 is operated with the operation lever 24 provided below the oven 4 is illustrated, but the operation lever 4 may be provided on the side of the oven 4. Further, in the first embodiment, the configuration in which the rear side of the lower heater 43 is movable up and down is illustrated, but a configuration in which the left side or the right side of the lower heater 43 is operated up and down is also possible.

  Furthermore, it is good also as a structure which can move the upper heater 42, In this case, the cleaning property of the ceiling surface of the oven 4 can be improved. When the upper heater 42 is configured to be movable, the rear side of the upper heater 42 may be a fulcrum, and the left or right side may be a fulcrum. Furthermore, an operation lever for operating the upper heater 42 may be provided on any of the upper and left sides of the opening 14 d of the oven 4.

  Further, the operation lever 24 may be omitted, and the heater 23 may be moved using the arm 23 directly projecting from the flange, or the heater may be moved electrically instead of being moved manually. In addition, when moving a heater electrically, it is desirable to make a heater movable only when the internal temperature which the temperature sensor provided in the cooking chamber 14 observes is less than predetermined.
