Description

Technical Field

[0001] This invention relates to a heating cooker with a mesh and a heater inside the housing. Background Technology

[0002] Japanese Patent Publication No. 2012-137232 discloses a heating cooker with heaters arranged vertically on the inner side of the housing and a mesh arranged between the heaters. An opening is formed on the front surface of the housing, and a door with a left-right rotation axis is provided in this opening. A hook is installed on the door. The hook passes through the mesh from bottom to top and engages with the mesh. The hook and mesh move forward and backward as the door opens and closes.

[0003] However, if the net needs to be cleaned, the user must remove the net from the hook. Summary of the Invention

[0004] The purpose of this invention is to provide a heat cooker that is easy to maintain and manage.

[0005] The heating cooker of technical solution 1 includes: a housing with an opening on the front side; a heater disposed within the housing; a mesh disposed within the housing and movable back and forth; a door that rotates about the edge of the opening to open and close the opening; and a hook mounted on the inner surface of the door, the hook and the mesh being configured such that: when the door moves from a closed position to an open position, the hook engages the mesh, and when the door is in the open position, the engagement of the hook and the mesh is released.

[0006] When the door is between the open and closed positions, that is, during the opening action, the hook engages with the net, causing the net to move forward. When the door is in the open position, the hook is released. Therefore, users do not need to remove the hook from the net to remove it from the housing, making maintenance easier.

[0007] In the heating cooker of technical solution 2, a hook hole is formed at the front end of the mesh for the hook to catch. When the door is in the open position, the hook is positioned axially away from the hook hole. When the door moves from the closed position to the open position, the hook is inserted into the hook hole or positioned axially at the same position as the hook hole.

[0008] With the door in the open position, the hook is in the position away from the hook-and-hold hole. Because it is away from the mesh, it prevents the user from contacting the hook. During the door opening action, the hook inserts into the hook-and-hold hole, or is in the same axial position as the hook-and-hold hole, and the mesh moves forward.

[0009] The heating cooker of technical solution 3 has an L-shaped hook with a first side and a second side perpendicular to the first side. When the door is in the closed position, the first side extends axially along the hook hole in front of the hook hole, and the second side extends rearward and is disposed next to the hook hole in the axial direction. At the end of the second side, an extension is formed that extends toward the hook hole. An inclined surface is formed at the rear of the extension, and the front-to-back width of the inclined surface decreases towards the extension end.

[0010] When the door is to be closed, as the protruding part contacts the edge of the hook hole, the edge easily moves along the inclined surface toward the protruding end of the protruding part. As a result, the edge easily extends beyond the protruding end and is hooked by the hook.

[0011] The heating cooker of technical solution 4 has a hook having a first part and a second part. The first part extends from the door, and the second part extends from the extended end of the first part in a direction intersecting the first part. An inclined surface is formed on the second part, and the width of the inclined surface in the direction orthogonal to the door becomes shorter towards the extended end of the second part.

[0012] When the door is to be closed, as the second part contacts the edge of the hook hole, the edge easily moves along the inclined surface toward the protruding end of the second part. As a result, the edge easily extends beyond the protruding end and is hooked by the hook.

[0013] The heating cooker of technical solution 5 has a groove extending back and forth on the inner side of the housing for inserting the mesh, and a gap is formed between the inserted mesh and the side of the groove in a direction perpendicular to the mesh.

[0014] In a direction perpendicular to the net, the net is easy to move, and when the hook touches the net, the net is easy to go beyond the end of the hook and get caught.

[0015] The heating cooker of technical solution 6, wherein the mesh includes: a mesh portion; a frame portion disposed on the periphery of one side of the mesh portion; and a support portion that overlaps with the frame portion on the opposite side of the mesh portion and is inserted into the groove to support the mesh portion.

[0016] On one side of the mesh section, the support portion overlaps the frame portion. Therefore, the first distance between the heater and the one side when the mesh is positioned with that one side facing the designated heater differs from the second distance between the heater and the other side when the mesh is positioned with the other side facing the heater. The user can choose whether one side or the other side faces the heater to adjust the temperature of the heated object.

[0017] The heating cooker of technical solution 7 includes a mesh with an extension extending in a direction perpendicular to the mesh. The heating cooker includes a guide and a locking part. The guide is formed on the inner side of the housing and extends back and forth to guide the mesh. The locking part is formed on the inner side of the housing and is located above or below the guide, and is used to lock the extension when the mesh moves forward.

[0018] The guide section guides the net forward and backward, allowing it to be stored in or removed from the housing. When the net moves to the front, the protrusion engages with the locking part to prevent the net from spilling out of the housing.

[0019] The heating cooker of technical solution 8 includes a limiting part, which abuts against the guiding part when the net is received into the housing in a predetermined posture, thereby restricting the movement of the net.

[0020] When the mesh needs to be placed into the housing in a prescribed posture, such as an abnormal posture, the movement of the mesh can be restricted by the limiting part. Therefore, the user of the heating cooker can identify that the mesh is placed into the housing in an abnormal orientation. Attached Figure Description

[0045] Implementation Method 1

[0046] The present invention will now be described based on the accompanying drawings illustrating a heating cooker according to Embodiment 1. In the following description, the directions up, down, front, back, left, and right shown in the drawings will be used. Figure 1 This is a perspective view of the heating cooker with door 7 in the closed position. (See image.) Figure 1 As shown, the heating cooker includes a rectangular housing 1. A rectangular opening 1a is formed on one side of the housing 1 (see reference). Figure 2 The housing 1 is configured with the opening 1a facing forward. The opening 1a has left and right edge portions extending in the vertical direction and upper and lower edge portions extending in the horizontal direction.

[0047] A rectangular door 7 with an opening 1a is positioned at the front of the opening 1a, with its lower edge connected to the lower side of the opening 1a at both ends. The door 7 can rotate around the lower edge of the opening 1a. When the door 7 is in the closed position, a handle 4 is provided on the upper surface of its outer surface, and a display 6 for displaying information such as target temperature or drive time, and an operating part 5 for setting the target temperature or drive time, are provided on the lower surface of its outer surface. A rectangular transparent window 3 is provided in the center of the door 7. The closed position refers to the position where the door 7 covers the opening 1a in an attitude approximately parallel to the front surface of the housing 1.

[0048] Figure 2 Therefore Figure 1 The II-II line is the cut-off line; this is a right-side sectional view of the heating cooker with door 7 in the closed position. (See attached image.) Figure 2 As shown, an upper reflector 11 is provided on the upper surface inside the housing 1. The central portion of the upper reflector 11 in the front-rear direction is bent to extend upward. An upper heater 10 extending in the left-right direction is disposed below the central portion of the upper reflector 11. A lower reflector 13 is provided on the lower surface inside the housing 1. The central portion of the lower reflector 13 in the front-rear direction is bent to extend downward. A lower heater 12 extending in the left-right direction is disposed above the central portion of the lower reflector 13.

[0049] like Figure 2 As shown, an upper protrusion 14 is formed on the left side of the inner side of the housing 1. The upper protrusion 14 extends in a direction perpendicular to the left side of the housing 1 and extends back and forth. The upper protrusion 14 is rectangular in shape when viewed from the side, and a downwardly extending protrusion 14a is formed on its lower edge. This protrusion 14a is formed between a portion slightly rearward of the front end of the lower edge and a portion slightly rearward of the center of the lower edge in the front-back direction.

[0050] Below the upper protrusion 14, a lower protrusion 15 is formed on the left side. The lower protrusion 15 extends in a direction perpendicular to the left side of the housing 1 and extends back and forth. The lower protrusion 15 is rectangular in shape when viewed from the side and is positioned away from the upper protrusion 14. The front and rear dimensions of the upper protrusion 14 and the lower protrusion 15 are approximately the same, and their front and rear positions correspond. In the vertical direction, the upper protrusion 14 and the lower protrusion 15 are positioned between the upper heater 10 and the lower heater 12.

[0051] A groove 17 is formed between the upper protrusion 14 and the lower protrusion 15. The vertical width of the groove 17 at the protrusion 14a is shorter than the vertical width at other parts.

[0052] Inside the housing 1, the right side of the housing 1 also has an upper protrusion 14, a lower protrusion 15, and a groove 17 (all omitted from the drawings), similar to the left side. The vertical and horizontal positions of the upper protrusion 14, lower protrusion 15, and groove 17 on the right side are approximately the same as those on the left side. The structure of the upper protrusion 14, lower protrusion 15, and groove 17 on the right side is the same as that on the left side, so detailed descriptions are omitted. Inside the housing 1, a forward-extending limiting part 16 is provided on the rear surface of the housing 1. In the vertical direction, the limiting part 16 is positioned between the upper protrusion 14 and the lower protrusion 15, that is, at approximately the same position as the groove 17. A mesh 2 can be inserted into the left and right grooves 17.

[0053] Figure 3 This is an oblique view of net 2. Figure 4 This is a partially enlarged oblique sectional view of net 2. Figure 5 This is a partially enlarged left view of the first support portion 21. The mesh 2 includes a rectangular grid-like mesh portion 20 when viewed from above. The mesh portion 20 extends in the left-right direction. A rectangular frame portion 23 is provided at the periphery of the mesh portion 20. The frame portion 23 is formed by bending a cylindrical member into a rectangle. The frame portion 23 is disposed on one surface of the mesh portion 20 and overlaps with said surface.

[0054] like Figure 3 and Figure 4 As shown, a rectangular frame-shaped first support portion 21 is provided on the left side portion 23b of the frame portion 23. The first support portion 21 is formed by bending a cylindrical member into a rectangle. The first support portion 21 includes two long sides extending in the front-rear direction and respectively disposed on the left and right sides, and two short sides 21c respectively disposed in the front and rear directions. The right long side is disposed on the upper side of the left side portion 23b, that is, disposed on the inner side of the mesh 2, and the left long side is disposed on the left side of the left side portion 23b, that is, disposed on the outer side of the mesh 2. Hereinafter, the long side disposed on the inner side of the mesh portion 2 will be referred to as the inner long side portion 21a, and the long side disposed on the outer side of the mesh 2 will be referred to as the outer long side portion 21b.

[0055] The inner long side 21a is mounted parallel to the left side 23b of the frame 23. In a direction perpendicular to the mesh 20, the left side 23b is sandwiched between the mesh 20 and the inner long side 21a. In other words, on one surface of the mesh 20 ( Figure 4 On the upper surface (the middle part), the left part 23b (frame part 23) and the inner long side part 21a are overlapped in sequence.

[0056] like Figure 5 As shown, in a direction perpendicular to the mesh portion 20, the outer long side portion 21b is closer to the mesh portion 20 than the inner long side portion 21a. In other words, in a direction perpendicular to the mesh portion 20, the outer long side portion 21b is positioned offset relative to the inner long side portion 21a. The front end of the inner long side portion 21a extends to a position further forward than the front portion 23a of the frame portion 23. The front end of the inner long side portion 21a is further forward than the front end of the outer long side portion 21b. The front ends of the inner long side portion 21a and the outer long side portion 21b are connected by the short side portion 21c, the first connecting portion 21d, and the second connecting portion 21e.

[0057] The short side portion 21c extends to the left at a right angle from the front end of the inner long side portion 21a. The first connecting portion 21d extends rearward from the left end of the short side portion 21c, parallel to the inner long side portion 21a. The rear end of the first connecting portion 21d and the front end of the outer long side portion 21b are connected by a second connecting portion 21e. As previously described, the outer long side portion 21b is positioned offset relative to the inner long side portion 21a; therefore, the second connecting portion 21e is inclined relative to the first connecting portion 21d and the outer long side portion 21b. The front short side portion 21c and the front first connecting portion 21d extend further forward than the front portion 23a.

[0058] like Figure 3 As shown, in the front-to-back direction, the rear end of the inner long side 21a is positioned approximately at the same level as the rear side of the frame 23. Figure 5 As shown, the rear ends of the inner long side portion 21a and the outer long side portion 21b are connected by a short side portion 21c, a first connecting portion 21d, and a second connecting portion 21e. The short side portion 21c extends to the left at a right angle from the rear end of the inner long side portion 21a. The first connecting portion 21d extends forward from the left end of the short side portion 21c, parallel to the inner long side portion 21a. The front end of the first connecting portion 21d and the rear end of the outer long side portion 21b are connected by the second connecting portion 21e. The second connecting portion 21e is inclined relative to the first connecting portion 21d and the outer long side portion 21b. In the front-rear direction, the rear short side portion 21c is positioned approximately at the same level as the rear portion of the frame portion 23.

[0059] A U-shaped second support portion 22 is provided on the outer long side portion 21b. The second support portion 22 is formed by bending a cylindrical component and includes a long side portion and two short side portions 22b. The two short side portions 22b extend from both ends of the long side portion at right angles. In the first support portion 21, a recess 21f is formed by the outer long side portion 21b and two second connecting portions 21e, in which the long side portion of the second support portion 22 is arranged parallel to the outer long side portion 21b. In a direction perpendicular to the mesh portion 20, the long side portion of the second support portion 22 is arranged adjacent to the outer long side portion 21b. The two short side portions 22b of the second support portion 22 are arranged one behind the other, with their heads facing the inner long side portion 21a. The heads of the short side portions 22b of the second support portion 22 are connected to the inner long side portion 21a. In a direction perpendicular to the mesh portion 20, the second support portion 22 is slightly outward than the inner long side portion 21a. Figure 4 (The upper side) extends out. Through the recess 21f, the extension width of the second support 22 is suppressed compared to when there is no recess 21f.

[0060] like Figure 4 As shown, hook holes 24 for hooking the hook 8, which will be described later, are formed at the front ends of the first support portion 21 and the second support portion 22. More specifically, rectangular hook holes 24 are formed by the front end of the inner long side portion 21a, the front short side portion 21c and the front first connecting portion 21d of the first support portion 21, and the front short side portion 22b of the second support portion 22. The hook holes 24 are located at the front of the mesh portion 20.

[0061] like Figure 3 As shown, a first support portion 21, a second support portion 22, and a hook hole 24 are also provided on the right side portion 23c of the frame portion 23. The structure of the first support portion 21 and the second support portion 22 provided on the right side portion 23c is the same as that of the first support portion 21 and the second support portion 22 provided on the left side portion 23b, except that they are symmetrical. Therefore, their detailed description is omitted.

[0062] When the mesh 2 is placed inside the housing 1, for example, one side of the mesh portion 20, i.e., the side with the first support portion 21 and the second support portion 22, faces upwards, the hook hole 24 is placed at the front, and the first support portion 21 and the second support portion 22 are inserted into the left and right slots 17. The first support portion 21 is supported by the lower side surface (lower protrusion 15) of the slot 17.

[0063] The user can also, as needed, place the other side of the mesh section 20 (the side without the first support 21 and the second support 22) upwards, and insert the first support 21 and the second support 22 into the left and right slots 17, thereby placing the mesh 2 inside the housing 1. When the other side of the mesh section 20 is facing upwards, the second support 22 is supported by the lower side (lower protrusion 15) of the slot 17, so the distance between the mesh section 20 and the upper heater 10 is shorter compared to the case where one side of the mesh section 20 is facing upwards.

[0064] The vertical dimension between the protruding portion 14a of the upper protrusion 14 and the lower protrusion 15 is larger than the vertical dimension of the first support portion 21 and the second support portion 22. Therefore, a gap is formed between the first support portion 21 and the second support portion 22 and the upper side surface of the groove 17. That is, a gap is formed between the mesh 2 and the side surface of the groove 17 in a direction perpendicular to the mesh portion 20.

[0065] Figure 6 yes Figure 2 A simplified partial right view of the area enclosed by line VI. On the inner surface of door 7, two hooks 8 are respectively located on the outer sides of the left and right edges of window 3 (see description below). Figure 9 The hook 8, viewed from the side, is L-shaped, having a first side 8a and a second side 8b extending at a right angle from one end of the first side 8a. The first side 8a is located slightly closer to the lower edge of the opening 1a than the center of the door 7, and the second side 8b is positioned closer to the lower edge than the first side 8a, that is, closer to the fulcrum of the door 7 (the portion connecting to the lower edge of the opening 1a). The second side 8b extends approximately at a right angle relative to the inner surface of the door 7. Figure 2 and Figure 6 As shown, when the door 7 is in the closed position, the first side 8a is fixed to the door 7, the other end of the first side 8a faces upward, and the protruding end of the second side 8b faces backward.

[0066] At the other end of the first side portion 8a, a first protrusion 8c is formed, extending in a direction perpendicular to the door 7. The width of the first protrusion 8c near the second side portion 8b gradually decreases as it approaches the second side portion 8b. At the protruding end of the second side portion 8b, a second protrusion 8d is formed, extending towards the side of the first protrusion 8c in a direction parallel to the door 7. On the portion of the second protrusion 8d opposite to the door 7, an inclined surface 8e is formed, and on the portion of the second protrusion 8d on the side of the door 7, a second inclined surface 8f is formed. The inclined surfaces 8e and 8f are inclined, and the width of the second protrusion 8d in the direction perpendicular to the door 7 decreases towards the end of the second protrusion 8d. That is, when viewed from the side, the inclined surfaces 8e and 8f are inclined at an acute angle. At the junction of the inclined surfaces 8e and 8f, that is, at the end of the second protrusion 8d, a curved surface 8g is formed.

[0067] like Figure 2 and Figure 6 As shown, in the vertical direction, the portion of the hook 8 located between the first protrusion 8c and the second protrusion 8d is recessed. When the door 7 is in the closed position, the recessed portion is positioned approximately at the same location as the slot 17. When the hook hole 24 is positioned at the front and the net 2 is inserted into the left and right slots 17 until it abuts against the limiting portion 16, the front end portion of the net 2 (hook hole 24) is positioned in the recessed portion of the hook 8 (the portion between the first protrusion 8c and the second protrusion 8d).

[0068] That is, the first side portion 8a extends in front of the hook hole 24 and in the axial direction (vertical direction) of the hook hole 24, and the second side portion 8b extends rearward and is disposed next to (below) the hook hole 24 in the axial direction. The second protrusion 8d extends towards the side (upper side) of the hook hole 24.

[0069] Figure 7 This is a right sectional view of a heating cooker showing the state in which door 7 is hooked by hook 8 during the movement of the door from the closed position to the open position. Figure 8 This is a right-side sectional view of the heating cooker with door 7 in the open position. Figure 9 This is a perspective view of the heating cooker with door 7 in the open position. Figure 10 This is an explanatory diagram illustrating the movement trajectory P of the end portion of the second protrusion 8d. Figures 7-9 In the middle, the object to be heated 50 is placed on the mesh 2. The open position refers to the position where the door 7 is positioned approximately at a right angle to the front surface of the housing 1, thus opening the opening 1a (see reference). Figure 8 and Figure 9 ). Figure 10In the middle, the single-dot dashed line indicates the position of the inner front edge of the hook hole 24 in the vertical direction. The hook 8 in the closed position is shown on the last side, and the hook 8 in the open position is shown on the front side.

[0070] After door 7 begins to rotate from the closed position to the open position, the second protrusion 8d of hook 8 is inserted into hook hole 24, or the second protrusion 8d of hook 8 is positioned axially (vertically) in the same direction as hook hole 24. The second protrusion 8d is hooked by the front edge of hook hole 24. Net 2 moves forward as door 7 rotates (see reference). Figure 7 The end portion of the second protrusion 8d reaches the front of the front surface of the housing 1 at a distance D from the front surface (refer to...). Figure 10 After reaching the open position, the hook 8 is released. With the door in the open position, the door 7 remains stationary (see reference). Figure 8 and Figure 9 Net 2 is pulled out of housing 1 by a distance D, and hook 8 leaves net 2. The distance D is, for example, 9-10 cm. Hook 8 is positioned below net 2 and does not extend above net 2. That is, in the axial direction (vertical direction) of hook hole 24, hook 8 is positioned away from hook hole 24.

[0071] like Figure 10 As shown, the movement trajectory P of the second protrusion 8d is an upwardly convex arc shape. Therefore, in the range between the front surface of the housing 1 and a position at a distance D away from the front surface, the forward movement speed of the net 2 at the front of the range is smaller than the forward movement speed of the net 2 at the center of the range. That is, the pulling speed of the net 2 gradually decreases, which can suppress the net 2 from extending too far forward.

[0072] Even with a small hook 8, the distance between the hook 8 and the fulcrum of the rotating door 7 (the part connected to the lower edge of the opening 1a) can be relatively long, allowing for a longer pull-out distance D of the mesh 2. Therefore, the heated object 50, located at the rear of the mesh 2, can be easily removed. Because the hook 8 is small and positioned away from the mesh 2, it prevents the user's hand from touching the hook 8 when removing the heated object 50. Furthermore, in the open position, the hook 8 does not extend to the top of the mesh 2, so even a large heated object 50 can be easily placed on the mesh 2.

[0073] Users can easily pull the mesh 2 out of the slot 17 and remove it from the housing 1, making it easy to clean the mesh 2 and the inside of the housing 1. Moreover, since the heated food 50 can be removed from the housing 1 along with the mesh 2, the cooked food can be efficiently placed on the dining table.

[0074] Figure 11 This is a right-side sectional view of the heating cooker showing the state in which the hook 8 contacts the mesh 2 during the movement of door 7 from the open position to the closed position. Figure 8 and Figure 9 When the door 7 is moved from the open position to the closed position, the second protrusion 8d is inserted into the hook hole 24, and the recessed portion between the first protrusion 8c and the second protrusion 8d of the hook 8 abuts against the front outer edge of the hook hole 24. The hook 8 pushes the mesh 2 backward. When the door 7 is rotated to the closed position, the mesh 2 moves backward to abut against the limiting part 16.

[0075] Figure 12 This is a right-side sectional view of a heating cooker showing the state in which the hook 8 abuts against the front end of the mesh 2 housed within the housing 1. For example, with the door 7 in the open position, the mesh 2 inserted into the slot 17, and the front end of the mesh 2 positioned between the front surface of the housing 1 and a distance D from that front surface, when the door 7 is moved to the closed position, the rear portion of the second protrusion 8d abuts against the front outer edge of the hook hole 24. The second protrusion 8d pushes the mesh 2 rearward.

[0076] Figure 13 This is an explanatory diagram illustrating the process of inserting the second protrusion 8d, located on the front side of the hook-and-loop hole 24, into the hook-and-loop hole 24. (See diagram for reference.) Figure 13 As shown by the solid line, the inclined surface 8e of the second protrusion 8d abuts against the front outer edge of the hook hole 24. Figure 13 As shown by the dashed line, the door 7 rotates, and the second extension 8d moves downward. The mesh 2 is pushed by the second extension 8d. As described above, since there is a gap between the mesh 2 and the groove 17, the pushed mesh 2 can move upward. Therefore, the front edge of the hook hole 24 contacts the inclined surface 8e while moving upward.

[0077] like Figure 13 As shown by the double-dotted line, the door 7 rotates further, and the front edge of the hook hole 24 passes over the end of the second protrusion 8d, i.e., the curved surface 8g, and is positioned in front of the second inclined surface 8f, and the second protrusion 8d is inserted into the hook hole 24.

[0078] In the heating cooker of Embodiment 1, when the door 7 is between the open and closed positions, that is, during the opening action of the door 7, the hook 8 engages with the mesh 2, causing the mesh 2 to move forward. When the door 7 is in the open position, the hook 8 is released. Therefore, when the user wants to remove the mesh 2 from the housing 1, it is not necessary to remove the hook 8 from the mesh 2, making maintenance and management easier.

[0079] With door 7 in the open position, hook 8 is in a position away from hook hole 24. Because it is away from mesh 2, it prevents the user from contacting hook 8. During the opening action of door 7, hook 8 is inserted into hook hole 24 or is in the same axial position as hook hole 24, and mesh 2 moves forward.

[0080] When closing door 7, if the second protrusion 8d contacts the outer edge of the hook hole 24, the outer edge easily moves along the inclined surface 8e towards the protruding end of the second protrusion 8d. As a result, the edge of the hook hole 24 easily extends beyond the protruding end and is hooked by the hook 8. Moreover, in a direction perpendicular to the mesh 2, the mesh 2 easily moves, and if the hook 8 touches the mesh 2, the mesh 2 easily extends beyond the end of the hook 8 and is hooked.

[0081] On one side of the mesh portion 20, the first support portion 21 and the second support portion 22 overlap with the frame portion 23. Therefore, the first distance differs from the second distance, where the first distance is the distance between the upper heater 10 and the mesh portion 20 when one side is positioned facing the upper heater 10, and the second distance is the distance between the upper heater 10 and the mesh portion 20 when the other side of the mesh portion 20 is positioned facing the upper heater 10. The user can choose whether one side or the other side faces the upper heater 10 to adjust the temperature of the heated object 50.

[0083] The present invention will now be described based on the accompanying drawings illustrating a heating cooker according to Embodiment 2. In Embodiment 2, structures identical to those in Embodiment 1 are given the same reference numerals, and detailed descriptions thereof are omitted. Figure 14 This is a right-side sectional view of a heating cooker with door 7 in the closed position.

[0084] like Figure 14 As indicated by the arrow, door 7 can rotate around the upper edge of opening 1a. A handle 4 is provided on the lower side of the outer surface of door 7. Hook 8 has an inverted L-shape. The structure of hook 8 is the same as that of hook 8 in Embodiment 1, except that it is symmetrical about the top and bottom. Embodiment 2 can achieve the same effect as Embodiment 1.

[0085] Implementation Method 3

[0086] The present invention will now be described based on the accompanying drawings illustrating a heating cooker according to Embodiment 3. In Embodiment 3, structures identical to those in Embodiments 1 or 2 are given the same reference numerals, and detailed descriptions thereof are omitted. Figure 15 This is the main sectional view of net 2. Figure 16 This is a top sectional view of a heating cooker with door 7 in the closed position.

[0087] like Figure 15 As shown, at the front end of the right portion 23c of the frame portion 23, an annular member 25 is provided on the first support portion 21. The annular member 25 has a hook hole 24 with the left-right direction as the axial direction. Figure 16As indicated by the arrow, door 7 can rotate around the left edge of opening 1a. A handle 4 is provided on the right edge of the front of door 7. A hook 8 is provided on the right edge of the rear surface of door 7, and a second protrusion 8d extends to the left. Embodiment 3 can achieve the same effect as Embodiment 1 or 2. Furthermore, door 7 can also rotate around the right edge of opening 1a. In this case, an annular member 25 is provided on the left side portion 23b of frame 23, and hook 8 is provided on the left edge of the rear surface of door 7.

[0088] Implementation Method 4

[0089] The present invention will now be described based on the accompanying drawings illustrating the heating cooker of Embodiment 4. In Embodiment 4, structures identical to those in Embodiments 1 through 3 are given the same reference numerals, and detailed descriptions thereof are omitted. Figure 17 This is a sectional oblique view showing the heating cooker with door 7 open. Figure 17 The description of Net 2 is omitted. For example... Figure 17 As shown, in embodiment 4, three lower heaters 12 are included. The number of lower heaters 12 is not limited.

[0090] like Figure 17 As shown, a first guide portion 18a and a second guide portion 18b are formed on the left side of the housing 1, inside the housing 1. The first guide portion 18a extends from the left side to the right and extends back and forth. The second guide portion 18b is disposed behind the first guide portion 18a and separates from it. The second guide portion 18b extends from the left side to the right and extends back and forth. The front-to-back dimension of the second guide portion 18b is longer than that of the first guide portion 18a.

[0091] A locking portion 18c is formed on the left side of the housing 1. The locking portion 18c is positioned between the first guide portion 18a and the second guide portion 18b in the front-rear direction, and is positioned higher than the first guide portion 18a and the second guide portion 18b. The locking portion 18c extends from the left side to the right and extends front-rear. A protrusion 18d is formed on the left side. This protrusion 18d is positioned behind the second guide portion 18b. The right side of the housing 1 also has a first guide portion 18a, a second guide portion 18b, a locking portion 18c, and a protrusion 18d. The front-rear positions of the first guide portion 18a, the second guide portion 18b, the locking portion 18c, and the protrusion 18d on the right side of the housing 1 are approximately the same as those on the left side. The mesh 2 is positioned in the left-right direction by means of the left and right protrusions 18d.

[0092] On the inner surface of door 7, two hooks 8 are respectively provided on the left and right edges of the inner surface of door 7. Figure 17Only the left hook 8 is shown. Hook 8 includes a first portion 8m extending approximately at a right angle from door 7, and a second portion 8h extending from the protruding portion of the first portion 8m toward the handle 4 (the upper side after door 7 is closed). An inclined surface 8k is formed at the protruding end of the second portion 8h, and the width of the inclined surface 8k in the direction orthogonal to the door 7 (the front-back direction after door 7 is closed) decreases towards the protruding end. In the direction orthogonal to the door 7, the inclined surface 8k forms on both sides of the second portion 8h.

[0093] On the inner surface of the door 7, two abutment portions 9 are respectively provided on the upper side of the two hooks 8. The abutment portion 9 is in the shape of a right-angled trapezoid, with the upper base 9a shorter than the lower base 9b. When the door 7 is closed, the first foot 9c, which is perpendicular to the upper base 9a and the lower base 9b, is located on the upper side, and the second foot 9d, which is inclined relative to the upper base 9a and the lower base 9b, is located on the lower side, with the lower base 9b located on the front side and the upper base 9a located on the rear side. When the door 7 is closed, the second foot 9d is inclined relative to the inner surface of the door 7 in a manner that increases towards the rear.

[0094] Figure 18 This is a simplified oblique view of net 2. Figure 19 This is a simplified top view of Net 2. Figure 20 This is a simplified enlarged right view of mesh 2. Mesh 2 includes mesh portion 20, lower frame 231, and upper frame 232. Mesh portion 20 is rectangular in shape when viewed from above and extends to the left and right. Lower frame 231 is provided along the outer periphery of the lower surface of mesh portion 20, and upper frame 232 is provided along the outer periphery of the upper surface of mesh portion 20.

[0095] A first support portion 210 and a second support portion 220 are provided on the right side of the lower frame 231 and the upper frame 232. The first support portion 210 is rectangular in shape when viewed from above and extends front to back. The first support portion 210 includes a first long side portion 211 and a second long side portion 212 that extend front to back. The first long side portion 211 is located to the left of the second long side portion 212, and the front and rear dimensions of the first long side portion 211 and the second long side portion 212 are approximately the same. The front ends of the first long side portion 211 and the second long side portion 212 are connected by a short side portion 213. The rear ends of the first long side portion 211 and the second long side portion 212 are connected by a short side portion 214. The front ends of the first long side portion 211 and the second long side portion 212 and the short side portion 213 extend to a position that is forward of the front edge of the mesh portion 20, the lower frame 231 and the upper frame 232. The rear ends of the first long side portion 211 and the second long side portion 212 and the short side portion 214 are located in front of the rear edges of the mesh portion 20, the lower frame 231 and the upper frame 232.

[0096] The first long side 211 is fixed to the right side of the lower frame 231 and the upper frame 232. For example... Figure 20As shown, the first long side portion 211 is positioned approximately midway between the lower frame 231 and the upper frame 232. The first long side portion 211 is mounted on the lower frame 231 and the upper frame 232. A limiting portion 212a extending upwards is formed at the front of the second long side portion 212. The limiting portion 212a extends to a position higher than the upper frame 232. On the second long side portion 212, an inclined portion 212b is formed at the rear of the limiting portion 212a, tilting downwards as it moves rearwards. An inclined portion 212c is formed at the rear end of the second long side portion 212, tilting upwards as it moves rearwards. The vertical position of the rear end of the inclined portion 212c is approximately the same as the vertical position of the first long side portion 211. Figure 20 As shown, the vertical position of the portion between the inclined portion 212b and the inclined portion 212c on the second long side 212 is approximately the same as the vertical position of the lower frame 231.

[0097] A recess is formed between inclined portions 212b and 212c. A second support portion 220 is provided in the recess between inclined portions 212b and 212c. The second support portion 220 is L-shaped in plan view and includes a short side portion 221 and a long side portion 222. The short side portion 221 extends from the first long side portion 211 to the right on the left side of the inclined portion 212b. The extended end of the short side portion 221 is located at the front end of the recess. The long side portion 222 extends rearward from the extended end of the short side portion 221 to the vicinity of the inclined portion 212c.

[0098] An upwardly extending portion 222a is formed at the rear end of the long side portion 222. That is, the extending portion 222a extends in a direction perpendicular to the mesh portion 20. The extending portion 222a slopes upwards as it moves rearwards from the middle of the long side portion 222. The rear end of the extending portion 222a slopes downwards. The extending portion 222a is substantially flat between the upward and downward slope portions.

[0099] The hook hole 240 is formed by the portion surrounded by the short side portion 221, the short side portion 213, the portion of the first long side portion 211 located between the two short side portions 221 and 213, and the portion of the second long side portion 212 located between the two short side portions 221 and 213. The aforementioned limiting portion 212a is located at the right edge of the hook hole 240.

[0100] On the left side of the lower frame 231 and the upper frame 232, a first support portion 210 and a second support portion 220 are provided, similar to those on the right side. The structures of the first support portion 210 and the second support portion 220 on the left side are the same as those on the right side, except that they are symmetrical. Therefore, a detailed description of the structure of the first support portion 210 and the second support portion 220 on the left side is omitted.

[0101] Figure 21This is a simplified right-side cross-sectional view of a heating cooker with the mesh 2 housed in the housing 1 and the door 7 closed. The mesh 2 is inserted from the front side between the locking portion 18c and the first guide portion 18a and the second guide portion 18b, with the limiting portion 212a facing upwards. That is, the second long side portion 212 and the long side portion 222 are inserted between the first guide portion 18a, the second guide portion 18b, and the locking portion 18c. The first guide portion 18a and the second guide portion 18b guide the mesh 2 in the front-rear direction. When the protrusion 222a is inserted under the locking portion 18c, the protrusion 222a is elastically deformed by the downward force exerted by the locking portion 18c. With the protrusion 222a deformed, the mesh 2 is further inserted rearwards. When the protrusion 222a is positioned behind the locking portion 18c, the protrusion 222a moves upwards due to the elastic restoring force, returning to its original shape. When the mesh 2 is housed in the housing 1, the protrusion 222a is positioned higher than the locking portion 18c. When the mesh 2 is housed in the housing 1, the limiting portion 212a is positioned in front of the locking portion 18c and above the first guide portion 18a, without interfering with the first guide portion 18a.

[0102] like Figure 21 As shown, with door 7 closed, the first part 8m of hook 8 extends rearward, and the second part 8h extends upward. The second part 8h is positioned below the hook hole 240.

[0103] Figure 22 This is a simplified right-side cross-sectional view of the heated cooker with door 7 open. Figure 21 With door 7 open as shown, the second part 8h of hook 8 inserts into hook hole 240 and is hooked by the front edge of hook hole 240, moving forward, and net 2 moves forward. When the end part of the second part 8h reaches a position in front of the front surface of housing 1 and at a distance D1 from the front surface, the hook 8 is released, and the protrusion 222a is engaged at the rear end of locking part 18c. Because the protrusion 222a is engaged at locking part 18c, net 2 stops moving forward, and the distance D1 is limited to a specified range. When door 7 is opened, net 2 will not protrude to the outside of housing 1.

[0104] Figure 23 This is a simplified, enlarged right view of the heating cooker with door 7 closed. From... Figure 22With the door 7 closed as shown, the second part 8h of the hook 8 is inserted into the hook hole 240. The front edge of the hook hole 240, i.e., the short side 213, is pushed by the second foot 9d of the abutment part 9 and the inner surface of the door 7, causing the net 2 to move rearward. Since the distance D1 is limited within a specified range, the net 2 can remain in the position where the hook 8 is released. Therefore, when the door 7 is to be closed, the second part 8h can be smoothly inserted into the hook hole 240. Moreover, when the second part 8h contacts the short side 213, the short side 213 easily moves along the inclined surface 8k toward the protruding end of the second part 8h. As a result, the short side 213 easily exceeds the protruding end and is hooked by the hook 8.

[0105] Figure 24 This is a simplified right-side cross-sectional view of the heating cooker with the mesh 2 placed inside the housing 1 with the restrictor 212a facing downwards. The mesh 2 is inserted from the front between the locking part 18c and the first guide part 18a and the second guide part 18b. The restrictor 212a contacts the front part of the first guide part 18a. Because the restrictor 212a interferes with the first guide part 18a, the front end of the mesh 2 cannot be retracted into the housing 1. Therefore, the user of the heating cooker can recognize that the mesh 2 is inserted into the housing 1 with an abnormal orientation.

[0106] Alternatively, the locking portion 18c can be provided below the first guide portion 18a and the second guide portion 18b, so that the limiting portion 212a and the protruding portion 222a extend downward. The first guide portion 18a and the second guide portion 18b can also be continuous.

[0107] The hook 8 and the abutment 9 can be provided only on the left side or only on the right side. Even with the hook 8 and the abutment 9 only on the left or right side, the hook 8 can still hook onto the net 2, pulling the net 2 forward. Through the abutment 9 and the door 7, the net 2 can be stored in the housing 1. With the hook 8 and the abutment 9 only on the left side, when a right-handed user opens the door 7 to install or remove the fragment receiving tray (not shown) at the bottom of the housing 1, the user's right sleeve will not be caught by the hook 8 or the abutment 9. The same applies when the hook 8 and the abutment 9 are only on the right side, when a left-handed user opens the door 7.
