  However, in the gas cooker disclosed in Patent Document 1, when the tray is vigorously taken in and out, the open / close door also opens and closes the open portion in conjunction with the open / close door, so the open / close door hits members around the open portion. There was a problem that the sound was annoying.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a gas cooking utensil that can quietly open and close an opening / closing door even when a tray is vigorously put in and out.

  In order to achieve the above object, a gas cooking utensil according to the first aspect of the present invention is a cooking chamber for cooking a cooking object having an opening formed on the front surface, and a cooking chamber for cooking. A saucer having a grille on which an object is placed, a support shaft provided in the vicinity of the opening and extending in the left-right direction of the cooking chamber, and inserted through the support shaft, with the support shaft as a center. An opening / closing door that opens and closes the opening by rotating in the vertical direction of the cooking chamber, an urging means that biases the opening / closing door in a direction to open, and an abbreviation of the cooking chamber. A long hole extending in the front-rear direction, a long hole shaft loosely inserted in the long hole, provided in the left-right direction of the cooking chamber, one end pivotally connected to the open / close door, and the other end When the arm-shaped connecting member connected to the long hole shaft and the tray are stored in the cooking chamber, the long hole shaft Abutting and moving the elongated hole shaft to the rear of the cooking chamber along the elongated hole in a direction to close the open / close door against the urging force of the urging means via the connecting member. An opening / closing door control member to be rotated, and a resistance force applying means for applying a resistance force in a direction opposite to the rotation direction of the opening / closing door when the opening / closing door is opened / closed.

  Moreover, the gas cooker of the invention which concerns on Claim 2 is provided with the rotary damper in addition to the structure of the invention of Claim 1.

  In the gas cooker according to the first aspect, the opening is opened and closed by turning the open / close door around the support shaft provided in the vicinity of the opening of the cooking chamber. The open / close door is always urged in the opening direction by the urging means. A long hole shaft is loosely inserted into the long hole provided in the side wall of the cooking chamber, and the long hole shaft moves along the long hole. A connecting member is connected between the long hole shaft and the open / close door. Accordingly, the long hole shaft moves along the long hole through the connecting member by the rotation of the door. Here, when the tray is stored in the cooking chamber, the door control member comes into contact with the long hole shaft. And the opening / closing door control member moves the long hole axis | shaft to the back of a cooking chamber along a long hole. Then, the opening / closing door rotates in a closing direction against the biasing force of the biasing means via the connecting member connected to the long hole shaft. Thus, the opening of the cooking chamber is closed by the open / close door. In addition, when pulling out a saucer from a cooking chamber, an opening-and-closing door is opened by passing through the flow contrary to the above. And in this invention, since a resistance force provision means provides the resistance force of the reverse direction to the rotation direction of an opening / closing door with respect to an opening / closing door, when a saucer is put in and out vigorously by the user, it accompanies this. The opening / closing speed of the rotating opening / closing door can be reduced. Thereby, since the opening / closing door does not collide with the surroundings of the opening part of a cooking cabinet vigorously, the sound produced at the time of taking in and out of a saucer can be reduced. Furthermore, it is possible to prevent the periphery of the opening from being damaged.

  Moreover, in the gas cooking appliance which concerns on Claim 2, in addition to the effect of the invention of Claim 1, resistance can be easily applied with respect to rotation of an opening-and-closing door by using a rotary damper.

  Moreover, in the gas cooking appliance which concerns on Claim 3, in addition to the effect of the invention of Claim 2, the resistance force of a rotary damper is effectively transmitted to an opening / closing door via a 1st gear and a 2nd gear. can do. Moreover, even if the opening / closing door and the rotary damper are separated from each other, the resistance force of the rotary damper can be transmitted to the opening / closing door through the first gear and the second gear.

  Next, the structure of the rail mechanism 30 will be described. As shown in FIG. 4, the rail mechanism 30 includes a pair of fixed rails 31 fixed along the lower ends of the inner surfaces of the left and right side walls of the grill 45, and the inner side of the pair of fixed rails 31. A pair of first movable rails 32 supported to be slidable in the front-rear direction of the grill 45 and a pair supported to be slidable in the front-rear direction of the grill 45 along the inside of the pair of first movable rails 32. The second movable rail 33. In FIG. 4, only the right rails of the pair of rails are illustrated.

  Between the fixed rail 31 and the first movable rail 32, a roller unit (not shown) in which a plurality of small rollers are arranged in parallel is disposed. A similar roller unit (not shown) is also disposed between the first movable rail 32 and the second movable rail 33. Furthermore, a first stopper (not shown) is provided on the front end side of the fixed rail 31. On the rear end side of the first movable rail 32, a first locking portion (not shown) that locks to the first stopper when the first movable rail 32 is pulled out is provided. Accordingly, it is possible to prevent the first movable rail 32 from coming off from the fixed rail 31.

  A second stopper (not shown) is provided on the front end side of the first movable rail 32. On the rear end side of the second movable rail 33, a second locking portion (not shown) that locks to the second stopper when the second movable rail 32 is pulled out is provided. Thereby, it is possible to prevent the second movable rail 33 from coming off from the first movable rail 32. In the rail mechanism 30 having such a configuration, a front-side rectangular holding frame 40 for detachably holding the tray 60 is assembled on the front side of the pair of second movable rails 32.

  Here, the structure of the holding frame 40 will be described. As shown in FIG. 3, the holding frame 40 includes a long right frame portion 41 fixed to the right second movable rail 32 and a long left frame fixed to the left second movable rail 32. Portion 42, a long front frame portion 43 provided between the front end portion of the right frame portion 41 and the front end portion of the left frame portion 42, and the rear end portion and the left frame portion 42 of the right frame portion 41. It consists of the elongate back frame part 44 extended between the rear-end parts. Each of the right frame portion 41, the left frame portion 42, the front frame portion 43, and the rear frame portion 44 has a substantially L-shaped cross section orthogonal to the longitudinal direction.

  The right frame portion 41 and the left frame portion 42 are bent at substantially right angles along the inner surface of the second movable rail 32 while covering the upper surfaces of the pair of second movable rails 32. The right frame portion 41 is pivotally supported by one end portion of a connecting arm 53 (to be described later) of the door interlocking mechanism 50 on one end portion outside the portion covering the upper surface of the front frame portion 43 and on the front side of the grill box 45. An abutting portion 36 for abutting on the roller 55 and biasing to the back side of the grill 45 is provided. Although not described in detail, the left frame portion 42 is also provided with a contact portion (not shown) similar to the right frame portion 41. The contact portion 36 corresponds to the “opening / closing door control member” of the present invention.

  The bottom of the tray 60 is fitted to the inside of the holding frame 40 having such a configuration, and the left and right edges of the tray 60 are placed on the right frame 41 and the left frame 42. The tray 60 is held by the holding frame 40. The handle member 16 is connected to the front frame portion 43 of the holding frame 40.

  Next, the opening / closing structure of the door 15 will be described with reference to FIG. The open / close door 15 includes a rectangular main body frame 95. A glass window 96 that is a rectangular opening is formed in the approximate center of the main body frame 95. Side-view L-shaped support portions 97 and 98 that extend substantially at right angles to the back surface of the main body frame 95 are provided at both left and right ends of the main body frame 95. In these support portions 97 and 98, a support shaft insertion hole 99 through which the support shaft 48 is inserted is provided at each upper portion in a state in which the open / close door 15 is erected in the vertical direction. Under each of the support shaft insertion holes 99, connection holes 100 for rotatably supporting one end of a connection arm 53 described later are provided. A single glass plate 110 is fixed to the main body frame 95 so as to cover the glass window portion 96 from the back side.

  In the open / close door 15 having such a configuration, the support shaft 48 is inserted into the pair of support shaft insertion holes 99 and 99 of the support portions 97 and 98. And the longitudinal direction center part of the spindle 48 is fixed to the upper end part of the opening end which forms the opening part 8 of the grill warehouse 45, and the longitudinal direction both ends of the spindle 48 form the opening 12 of the housing | casing 2. Fixed to each inner surface. Thereby, the open / close door 15 rotates independently with respect to the support shaft 48.

  Further, coil-like torque springs 58 are externally attached to the left and right sides of the portion corresponding to the inside of the main body frame 95 in the support shaft 48. A loop-shaped fixing portion 58 a formed at one end of the torque spring 58 is fixed to the inner surfaces of the support portions 97 and 98 of the main body frame 59. On the other hand, the other end of the torque spring 58 is fixed to the support shaft 48. Then, the other end portion of the torque spring 58 is fixed to the support shaft 48 in a state where the fixing portion 58a is substantially horizontal. That is, the state in which the open / close door 15 is open is a state in which no torque is applied to the torque spring 58. Therefore, even if the opening / closing door 15 is rotated by its own weight, the open state of the opening / closing door 15 is maintained by the biasing force of the torque spring 58. The torque is applied to the torque spring 58 by closing the door 15. The torque spring 58 shown in FIG. 6 corresponds to the “biasing means” of the present invention.

  By the way, in the opening / closing structure of the opening / closing door 15 according to the present embodiment, in order to prevent the opening / closing door 15 from being opened and closed forcefully in conjunction with the insertion / removal of the tray 60, a predetermined rotation operation of the opening / closing door 15 is performed. Giving resistance. Therefore, a structure for giving resistance to the turning operation of the door 15 will be described in detail below.

  As shown in FIG. 6, first gears 70, which are substantially circular plates, are fixed to the inner surfaces of the support portions 97 and 98 provided at the left and right ends of the main body frame 95. An insertion hole 71 into which the support shaft 48 is loosely inserted is provided substantially at the center of the first gear 70. The insertion hole 71 is arranged corresponding to the support shaft insertion hole 99 provided in the support portion 97 (98). Further, a tooth portion having a large number of teeth is formed in the arc portion of the first gear 70. The support shaft 48 is inserted into the pair of support shaft insertion holes 99 and 99 of the support portions 97 and 98 and the insertion holes 71 and 71 of the first gears 70 and 70. As a result, the first gear 70 rotates about the support shaft 48 as the opening / closing door 15 rotates about the support shaft 48.

  On the other hand, rotary dampers 75 are respectively fixed to upper portions of the front side of the left and right side walls 46 of the grill 45 (only the rotary damper 75 on the right side of the grill 45 is shown in FIGS. 4 and 5). A second gear 76 is fixed to the tip of the rotary shaft 75 a of the rotary damper 75. On the outer periphery of the second gear 76, a tooth portion having a large number of teeth is formed.

  Further, the tooth portion of the first gear 70 and the tooth portion of the second gear 76 mesh with each other. Therefore, the rotary damper 75 applies a predetermined resistance to the rotation of the rotary shaft 75 a, so that the resistance is applied to the turning operation of the open / close door 15 through the second gear 76 and the first gear 70. It is like that. In the present embodiment, the opening / closing door 15 is opened and closed in conjunction with the insertion / removal of the tray 60. However, even when the tray 60 is withdrawn / removed vigorously, the opening / closing door 15 is subject to resistance to rotation, so the The door opening and closing speed can be reduced.

  Here, the rotary damper 75 will be described. As the rotary damper 75, for example, a rotary damper using a braking force (brake force) generated by the viscous resistance of oil can be used. The braking torque of the damper can be adjusted by the viscosity of the oil, the clearance between the rotor and the body case (not shown), the contact area of the oil, and the like. The braking torque of the rotary damper 75 varies depending on the rotational speed of use. That is, when the rotational speed increases, the torque increases, and when the rotational speed decreases, the torque decreases. Accordingly, when the rotation speed of the open / close door 15 is slow, the torque of the rotary damper 75 is lowered, so that the tray 60 is not affected. On the other hand, when the rotation speed of the open / close door 15 is fast, the torque of the rotary damper 75 is increased, which has the effect of slowing the tray 60 in and out. The rotary damper 75, the first gear 70, and the second gear 76 correspond to the “resistance force applying means” of the present invention.

  Next, the structure of the door interlocking mechanism 50 will be described. As shown in FIG. 4, the door interlocking mechanism 50 includes a connection arm 53 having one end side rotatably connected to a connection hole 100 provided in each of the support portions 97 and 98 of the opening / closing door 15, and the connection arm 53. A long hole shaft 54 provided at the other end and extending substantially at right angles to the grill 45, a roller 55 pivotally supported by the long hole shaft 54, and under the left and right side walls 46 of the grill 45 A long hole 51 is provided on the side and extending in the front-rear direction of the grill 45 to guide the roller 55.

  The connecting arm 53 is bent at two locations so as to bulge out toward the front of the grill 45. The long hole 51 extends substantially horizontally from the front side of the grill box 45 toward the back side in order to guide the other end of the connecting arm 53 to the back side of the grill box 45. Further, the movement of the other end of the connecting arm 53 when the door 15 is closed is restricted by bending upward on the back side.

  Next, the operation of the door interlocking mechanism 50 will be described. As shown in FIG. 4, first, in a state where the tray 60 is pulled out, the open / close door 15 is held in an open state by the bias of the torque spring 58. That is, since the open / close door 15 is bounced upward, the roller 55 pivotally supported on the other end of the connecting arm 53 is pulled back to the front side of the long hole 51 provided in the side wall 46 of the grill 45. It has become. Next, in order to store the tray 60 in the grill 45, the tray 60 is slid toward the inside of the grill 45 by pushing the handle member 16 toward the housing 2.

  Then, the abutting portion 36 provided on the holding frame 40 abuts on the roller 55 loosely inserted in the long hole 51 of the grill box 45. Further, by pushing the handle member 16, the abutting portion 36 urges the roller 55 toward the back side of the grill 45, so that the roller 55 rolls along the inner edge of the long hole 51. Then, when the roller 55 moves to the back side of the grill box 45, the other end of the connecting arm 53 is pulled to the back side of the grill box 45. Accordingly, the opening / closing door 15 is pulled and rotated downward against the bias of the torque spring 58.

  When the opening / closing door 15 rotates, the rotary damper 75 is connected via the second gear 76 provided at the tip of the rotary shaft 75 a of the rotary damper 75 and the first gear 70 fixed to the opening / closing door 15. The resistance force is given to the open / close door 15. Thereby, since the speed which rotates in the direction in which the door 15 closes becomes slow, it can prevent that the door 15 collides with the opening end of the grill 45 violently. Therefore, it is possible to reduce a collision sound when the open / close door 15 hits the opening end of the grill ware 45 and to prevent the periphery of the opening 8 of the grill ware 45 from being damaged.

  In addition, since the speed at which the opening / closing door 15 rotates in the closing direction is slowed, resistance is applied when the contact portion 36 biases the roller 55 moving along the long hole 51 toward the back side of the grill 45. As a result, the moving speed of the tray 60 is slowed, and the handle member 16 can be prevented from colliding with force around the opening 8 of the grill 45, so that the sound generated when the tray 60 is taken in and out can be reduced. It is possible to prevent damage around the opening 8 of the grill 45. In addition, it is possible to reduce the sound generated when the roller 55 rolls along the long hole 51, the sound generated when the connecting arm 53 moves, and the like.

  In this way, the tray 60 is stored in the grill 45, and the door 15 is completely closed (see FIG. 5) with the handle member 16 in contact with the opening end in front of the grill 45. At this time, the protrusion (not shown) fixed to the rear frame 44 of the holding frame 40 is sandwiched from both the left and right sides by a holding unit (not shown) fixed to the lower inner surface of the back wall of the grill 45. It is pinched. Thereby, the holding frame 40 is fixed in the grill 45.

  And when pulling out the saucer 60 out of a store | warehouse | chamber, it is reverse to the flow demonstrated above. As shown in FIG. 5, first, when the handle member 16 is gradually pulled forward, the urging force of the abutting portion 36 against the roller 55 disappears, so that the roller 55 moves as the abutting portion 36 moves forward. Move forward. This is because the biasing force of the torque spring 58 is dominant, so that the opening / closing door 15 is pushed up, and the roller 55 pivotally supported on the other end of the connecting arm 53 is pulled forward of the grill 45. It is.

  Also in this case, the resistance force of the rotary damper 75 is opened and closed via the second gear 76 provided at the tip of the rotary shaft 75 a of the rotary damper 75 and the first gear 70 fixed to the opening / closing door 15. It is given to the door 15. As a result, the speed at which the door 15 is rotated in the opening direction is slowed, so that the noise generated when the roller 55 rolls along the long hole 51, the sound generated when the connecting arm 53 moves, and the like are reduced. can do. Then, as shown in FIG. 4, in a state where the abutting portion 36 is separated from the roller 55 and the tray 60 is pulled out of the cabinet, the open / close door 15 is flipped up to completely open the opening 8 of the grill 45. It can be set as the state exposed to.

  As described above, according to the built-in stove 1 of the present embodiment, the open / close door 15 that opens and closes the opening 8 of the grill 45 is provided to be rotatable about the support shaft 48 provided in the grill 45. It has been. The open / close door 15 is rotated by the door interlocking mechanism 50 in conjunction with the insertion and removal of the tray 60 with respect to the grill 45. And if the 1st gear 70 provided in the opening / closing door 15 rotates with the opening / closing door 15, the rotating shaft 75a of the rotary damper 75 which has the 2nd gear 76 meshing with the 1st gear 70 in a front-end | tip part will be rotated. The rotary damper 75 imparts resistance to the turning operation of the open / close door 15 via the second gear 76 and the first gear 70. Thereby, even if the tray 60 is withdrawn / inserted with respect to the grill 45, resistance by the rotary damper 75 is given to the open / close door 15, and resistance is also given to the tray 60 being put in and out. Therefore, since the opening / closing speed of the open / close door 15 and the loading / unloading speed of the tray 60 can be slowed, the sound generated when the tray 60 is loaded / unloaded can be effectively reduced.

  In addition, the gas cooking appliance which concerns on this invention is not necessarily limited to the said embodiment, You may change variously in the range which does not deviate from the meaning. For example, in the above embodiment, the resistance of the rotary damper 75 is transmitted to the open / close door 15 via two gears, but two or more gears may be used. This is particularly effective when the opening / closing door 15 and the rotary damper 75 are located away from each other.

  Further, the structure may be such that the resistance of the rotary damper 75 directly acts on the rotation of the open / close door 15 without using a plurality of gears. In this embodiment, a torque spring 58 is attached to the support shaft 48 in order to constantly bias the opening / closing door 15 in the opening direction.
