  2. Description of the Related Art Conventionally, a double-sided grill is known in which an upper burner and a lower burner are provided on the upper and lower sides of the grill on the left and right inner surfaces of the grill cabinet. This double-sided grill has an advantage that the front and back of the object to be cooked can be heated at a time as compared with a general grill having only a pair of burners in the grill cabinet. However, since the upper burner and the lower burner are provided on the left and right inner surfaces in the grill cabinet, there is a problem that the parts cost and the gas consumption increase. Then, the grill which can bake the front and back of the to-be-cooked object on a grilling net evenly with a pair of burners by shaking a grilling net in a grill warehouse is proposed (for example, refer to patent documents 1). . In this grill, the rotational force of a step motor provided outside the grill box is transmitted to a rotating shaft by a rack and pinion mechanism, and the grill net fixed to the rotating shaft is swung within a predetermined angle range.

JP 2005-160932 A

  However, in the grill described in Patent Document 1, since the motor, which is a power source, is separated from the rotary shaft, it is necessary to lengthen the rack gear according to the distance. Therefore, it has been difficult to smoothly transmit the motor power to the rotating shaft. Further, in order to swing the grill, it is necessary to rotate the step motor in the forward and reverse directions, and there is a problem that the control of the step motor is troublesome. Furthermore, there is a problem that it is difficult to install the rack and pinion mechanism in a narrow instrument.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a cooking device with a grill that can swing a grill net easily and smoothly with a compact configuration. .

  A heating cooker with a grill according to claim 1 of the present invention is a grill warehouse having a front opening, grill burners provided on the left and right inner surfaces of the grill warehouse, and a grill net stored in the grill warehouse. A saucer provided below the grill, and a support means for swingably supporting the grill above the saucer, and the food to be cooked placed on the grill is heated by the grill burner. In the cooking device with a grill for cooking, the support means includes a rotating shaft that is rotationally driven by a motor, an eccentric cam provided on the rotating shaft, a support that supports the grill net upward, and the rotating shaft. Of the eccentric cam from both ends sandwiching the swinging shaft of the support in the center, and a swinging shaft that is provided in parallel with the rotating shaft and pivotally supports the support. Towards the circumferential side A pair of driven node members extending so as to sandwich the cam, and the eccentric cam has a non-uniform distance from the rotation shaft to the peripheral side surface as a rotation center, and receives the rotation of the rotation shaft. Thus, the eccentric cam performs an eccentric operation, and each of the tip ends of the pair of driven node members repeatedly receives the eccentric operation, whereby the support swings about the swing shaft.

  In addition to the configuration of the invention according to claim 1, the pair of driven node members is provided with the eccentricity from one end of the both ends of the support body. A first driven node member extending toward the peripheral side surface of the cam, and extending from the other end portion of the support opposite to the one end portion toward the peripheral side surface of the eccentric cam. The eccentric cam includes an action portion having a longest distance from the rotation center to the peripheral side surface on the peripheral side surface, and the eccentric operation causes the eccentric cam to move from the axial direction. As seen, when the eccentric cam rotates in one direction, the distance between the action portion and the tip portion of the first driven node member decreases, and the tip portion and the rotation of the first driven node member decrease. As the distance to the center increases, the circumference of the eccentric cam A first eccentric operation in which a surface biases the distal end portion of the first driven node member outward; a distance between the action portion and the distal end portion of the second driven node member; and the second As the distance between the distal end portion of the driven node member and the rotation center increases, a second eccentric operation in which the peripheral side surface of the eccentric cam biases the distal end portion of the second driven node member outward. It is an operation that repeats alternately.

  In addition to the configuration of the invention according to claim 1, the cooking device with grill of the invention according to claim 3 rolls with respect to the peripheral side surface at the tip of the driven node member. A roller is provided.

  In addition to the configuration of the invention according to any one of claims 1 to 3, the heating cooker with a grill according to the invention of claim 4 is provided with a plurality of eccentric cams on the rotating shaft, and the pair of driven node members are The support is provided according to the number of eccentric cams.

  In the heating cooker with a grill according to the first aspect of the present invention, the grill net swings in the grill cabinet by the support means. In the support means, the rotating shaft rotates by receiving the power of the motor, and the eccentric cam performs an eccentric operation by receiving the rotation of the rotating shaft. By repeatedly receiving the eccentric operation at the respective distal end portions of the pair of driven node members, the support swings around the swing shaft. Therefore, the grill net supported by the support can be smoothly swung in the grill cabinet. Thus, by using the eccentric cam, the rotational force of the rotating shaft by the motor can be converted into the swinging motion of the support. Therefore, the configuration can be made compact. Further, since the rotating shaft is only rotated in one direction, the grill net on the support can be easily swung. Furthermore, since the support can be continuously swung by rotating the rotating shaft in one direction, a smooth swinging operation of the grill can be realized.

  In addition, in the cooking device with a grill of the invention according to claim 2, in addition to the effect of the invention of claim 1, the first driven node member extends from one end of the support toward the peripheral side surface of the eccentric cam. Has been established. The second driven node member extends from the other end of the support toward the circumferential side surface of the eccentric cam. The eccentric cam includes an action portion on the peripheral side surface. An action part is a part with the longest distance from a rotation center to a peripheral side. When the eccentric cam rotates in one direction, the eccentric cam alternately repeats the first eccentric operation and the second eccentric operation. In the first eccentric operation, as the distance between the action portion and the tip portion of the first driven node member decreases and the distance between the tip portion of the first driven node member and the rotation center increases, the peripheral side surface of the eccentric cam becomes The front end portion of the first driven node member is urged outward. In the second eccentric operation, as the distance between the action portion and the tip of the second driven node member decreases and the distance between the tip of the second driven node member and the rotation center increases, the circumferential side surface of the eccentric cam becomes The tip of the second driven node member is biased outward. By repeating these operations alternately, the grill net on the support can be smoothly swung.

  In addition, in the cooking device with grill of the invention according to claim 3, in addition to the effect of the invention of claim 1 or 2, the roller provided at the tip of the driven node member rolls around the peripheral side surface of the eccentric cam. Therefore, the friction between the distal end portion of the driven node member and the peripheral side surface of the eccentric cam can be reduced.

  Moreover, in the heating cooker with a grill of the invention according to claim 4, in addition to the effect of the invention according to any one of claims 1 to 3, a plurality of eccentric cams are provided on the rotating shaft, and the pair of driven node members are: Since the support is provided in accordance with the number of eccentric cams, the grill net on the support can be stably swung.

  Next, the structure of the rotating shaft 70 will be described with reference to FIG. The rotating shaft 70 is housed in a rotating bearing body 101 (to be described later) of the rotating bearing unit 100 and includes a rear end shaft 79 guided to the back side of the grill 15. A connecting portion 73 for connecting to the rotary bearing unit 100 is provided in the vicinity of the rear end shaft 79. The connecting portion 73 is provided with a pair of fitting pieces 74 and 75 extending on both sides in the direction orthogonal to the rear end shaft 79. These fitting pieces 74 and 75 are fitted into a plurality of recesses 116 (see FIG. 5), which will be described later, provided in the rotary bearing body 101, respectively. Thereby, the rotating shaft 70 rotates with the rotation of the rotating bearing body 101.

  The rotating shaft 70 is provided with a pair of circular eccentric cams 91 and 92. As shown in FIG. 8, the eccentric cams 91 and 92 have a rotation center at a position away from the center P. A rotation shaft 70 is provided through the rotation center, and the cams 91 and 92 rotate as the rotation shaft 70 rotates. When the rotary shaft 70 is viewed from the front in the axial direction, the point K that is the intersection of the virtual straight line connecting the rotary shaft 70 and the center P and the outer periphery of the eccentric cam 91 is the longest axis that is farthest from the rotary shaft 70. This is the position of the part and corresponds to the “action part” of the present invention. The same applies to the eccentric cam 92. The phases of the eccentric cams 91 and 92 are adjusted to be the same.

  Next, the structure of the support plates 81 and 82 will be described. As shown in FIG. 2, the support plate 81 is formed in a substantially triangular shape when viewed from the front. At the lower end of the support plate 81, a fixing portion 81A bent at a substantially right angle is provided.

A bearing 77 of the swing shaft 41 is provided in the vicinity of the apex directed upward of the support plate 81, and a bearing 85 of the rotating shaft 70 is provided vertically below the support plate 81.

  On the other hand, the support plate 82 is also formed in a substantially triangular shape when viewed from the front. A fixing portion 82A bent at a substantially right angle is provided at the lower end of the support plate 82. The fixing portion 82A is fixed to the rear end portion 13B of the tray 13 by a fixing tool 89. A bearing 78 of the swing shaft 41 is provided in the vicinity of the apex directed upward of the support plate 82, and a bearing 86 of the rotating shaft 70 is provided vertically below the support plate 82. As shown in FIG. 3, a support piece 83 for rotatably supporting the center in the longitudinal direction of the rotating shaft 70 is provided at the center of the bottom of the tray 13. A bearing groove 83 </ b> A into which the rotation shaft 70 is rotatably inserted is provided on the upper portion of the support piece 83.

  Next, the structure of the rotary bearing unit 100 will be described with reference to FIG. The rotary bearing unit 100 includes a motor 95 fixed to the outer surface of the back wall 25, a substantially dish-shaped pedestal member 130 fixed to the inner surface of the back wall 25 and interposing the drive shaft 150 of the motor 95, and a drive shaft. 150, a substantially cylindrical rotary bearing body 101 coupled to the front end portion of 150 and supported so as to be retractable in the front-rear direction of the grill cabinet 15 through the insertion hole 27A of the partition wall 27, and the rotary bearing body 101 and the base member 130, and a coil spring 140 that biases the rotary bearing body 101 forward. The drive shaft 150 of the motor 95 extends forward through an insertion hole 25 </ b> A provided in the back wall 25. A through hole 131 is provided at the center of the base member 130, and the drive shaft 150 of the motor 95 is inserted into the through hole 131. The motor 95 is a “low-speed rotating motor” that generates a high torque. For example, a motor that rotates once in 40 seconds can be used.

  The rotary bearing body 101 includes a substantially cylindrical main body portion 102 and a substantially cylindrical rear extending portion 103 that is coaxially provided at the rear end portion of the main body portion 102 and has a smaller diameter than the main body portion 102. . Inside the rotary bearing body 101, in order from the front end side of the main body portion 102 toward the rear end side of the rearward extending portion 103, an introduction portion 111 formed with a large diameter, and from the introduction portion 111 to the back side A tapered portion 112 formed in a tapered shape and a storage portion 113 extending backward from the back side of the tapered portion 112 are provided.

  The introduction part 111 is a part for introducing the rear end shaft 79 of the rotary shaft 70 into the inside. The introduction part 111 is formed in a large diameter. Therefore, even when the rear end shaft 79 is pushed into the grill cabinet 15 in a state of being deviated from the center of the rotary bearing body 101, the rear end shaft 79 can be taken into the introduction portion 111. In addition, on the back side of the introduction portion 111, there are provided four convex portions 115 that are formed in a substantially cross position around the storage portion 113 and project forward in the axial direction when viewed from the axial direction. Yes. Between these four convex parts 115, the four recessed parts 116 dented back along the axial direction are provided. In the recess 116, fitting pieces 74 and 75 provided on the rear end shaft 79 of the rotating shaft 70 of the grill swing support mechanism 35 are fitted.

  A ring-shaped locking portion 118 extending outward in the radial direction is provided on the outer edge portion of the rear end of the main body portion 102. When the rotary bearing body 101 is moved forwardly biased by the coil spring 140 through the insertion hole 27 </ b> A of the partition wall 27, the locking portion 118 is locked to the back side of the partition wall 27. This prevents the rotary bearing body 101 from coming off from the insertion hole 27A. A ring-shaped groove portion 119 formed in a concave shape from the rear end surface of the main body portion 102 toward the front side in the axial direction is provided inside the locking portion 118 in the radial direction. One end of the coil spring 140 is pushed into and fixed to the groove 119. The other end side of the coil spring 140 is fixed by being pushed into the inside of the base member 130.

  A guide hole 120 penetrating perpendicularly to the longitudinal direction of the storage portion 113 and having a predetermined length in the longitudinal direction is provided on the rear end side in the axial direction of the storage portion 113. The predetermined length of the guide hole 120 is adjusted to a distance for moving the rotary bearing body 101 forward with respect to the base member 130. The front end side of the drive shaft 150 of the motor 95 is inserted from the rear end side of the storage portion 113. Inside the guide hole 120, a pair of locking pieces 151, 152 provided orthogonal to the longitudinal direction of the drive shaft 150 is disposed on the distal end side of the drive shaft 150 of the motor 95. Accordingly, when the drive shaft 150 rotates in one direction, the pair of locking pieces 151 and 152 are locked to the wall surface of the guide hole 120, so that the rotary bearing body 101 can rotate integrally with the drive shaft 150.

  Next, the flow until the tray 13 is pushed into the grill 15 and the rear end shaft 79 of the rotating shaft 70 is connected to the rotating bearing unit 100 and rotates is described with reference to FIGS. I will explain. First, when the tray 13 is pushed into the grill 15 by the user, the rear end shaft 79 is taken into the introduction portion 111 of the rotary bearing body 101 as shown in FIG. Here, when the rear end shaft 79 is displaced from the center of the rotary bearing body 101, the rear end shaft 79 contacts the wall surface of the tapered portion 112. Then, as the tray 13 is pushed into the grill 15, the rear end shaft 79 slides on the wall surface of the tapered portion 112. Accordingly, the position of the rear end shaft 79 is corrected with respect to the storage portion 113 that is the center of the rotary bearing body 101.

  Next, the rear end shaft 79 is inserted into the storage portion 113, but the positions of the pair of fitting pieces 74 and 75 provided on the rotating shaft 70 and the four concave portions 116 provided on the introduction portion 111 are aligned. Often not. In this case, as shown in FIG. 7B, the pair of fitting pieces 74 and 75 are in contact with the front end surfaces of any two of the four convex portions 115, respectively. At this time, the rotary bearing body 101 is pushed into the back side against the bias of the coil spring 140. Accordingly, even when the pair of fitting pieces 74 and 75 are not fitted into the recesses 116 and 116, the grill net 12 can be pushed into the grill box 15 and stored.

  Next, when the operation switch 7 is pressed in a state where the mode change switch 11 shown in FIG. 1 is switched to the “double-sided firing mode” by the user, power is supplied from the battery to the motor 95 simultaneously with the ignition of the grill burners 31 and 32. Is supplied, and the drive shaft 150 starts to rotate in one direction. Then, as shown in FIG. 5, the pair of locking pieces 151, 152 of the drive shaft 150 are locked to the wall surface of the guide hole 120 of the rotary bearing body 101, and the rotary bearing body 101 is integrated with the drive shaft 150. It rotates (see FIG. 6). Then, the rotary bearing body 101 continues to rotate while the respective front end surfaces of the convex portion 115 abut against the pair of fitting pieces 74 and 75.

  Next, when the positions of the fitting pieces 74 and 75 provided on the rotating shaft 70 coincide with the position of the recess 116 of the rotating bearing body 101, the rotating bearing body 101 is a coil spring as shown in FIG. It is urged forward by 140 and pushed forward at a stretch. At this time, the fitting pieces 74 and 75 of the rotating shaft 70 are fitted into the recess 116 of the rotating bearing body 101. As a result, the rotary shaft 70 is coupled to the drive shaft 150 of the motor 95 via the rotary bearing body 101, and thus rotates in one direction as the drive shaft 150 rotates. Then, when the rotary shaft 70 rotates, the grilling net swing support mechanism 35 is driven, and the grilling net 12 can be swung.

  Next, swinging of the grill 12 by the grill swing support mechanism 35 will be described with reference to FIGS. In the following description, as shown in FIG. 8, the rotation angle of the rotary shaft 70 is θ, the swing angle of the grill 12 is ψ, and the swing of the grill 12 when the rotary shaft 70 is viewed from the front side in the axial direction. Describe the behavior. In this embodiment, the rotating shaft 70 rotates clockwise when viewed from the front side in the axial direction, but may be rotated counterclockwise. The swing angle ψ of the grill 12 is + (see FIGS. 8 to 11) when the right end side is lowered from the horizontal state when viewed from the front side in the axial direction of the rotating shaft 70, and − (FIGS. 13 to 15) when it is raised. Reference). The XX line (two-dot chain line) is a reference line indicating the horizontal direction, and the ZZ line (two-dot chain line) is a reference line indicating the vertical direction. In this embodiment, the rotation angle θ of the eccentric cam 91 will be described. However, the eccentric cam 92 moves in the same manner, and the description thereof will be omitted.

  The swing angle ψ varies depending on the size of each part constituting the support unit 40, the distance between the rotation shaft 70 and the swing shaft 41, the tilt angle of the swing arms 51 to 54, and the like. Therefore, the swing angle ψ is not limited to the specific value shown below, but is shown as an index indicating the state in which the grill 12 swings according to the rotation angle θ of the rotating shaft 70.

  First, when the rotation angle θ of the rotating shaft 70 is 0 °, the point K of the eccentric cam 91 is at the lowest position as shown in FIG. In this state, the distance from the rotary shaft 70 to the roller 56 of the swing arm 51 is the same as the distance from the rotary shaft 70 to the roller 57 of the swing arm 52. That is, since the swing angle ψ = 0 °, the grill 12 is in a horizontal state.

  Next, when the rotation shaft 70 starts to rotate clockwise from the state of FIG. 8, the point K of the eccentric cam 91 gradually approaches the swing arm 52 side as shown in FIG. Therefore, the distance from the rotating shaft 70 to the roller 57 of the swing arm 52 gradually increases. Here, since the position of the rotating shaft 70 does not change, the roller 57 of the swing arm 52 is urged to the left by the peripheral side surface of the eccentric cam 91. On the other hand, the distance from the rotating shaft 70 to the roller 56 of the swing arm 51 gradually decreases. Therefore, the roller 56 of the swing arm 51 is not biased by the peripheral side surface of the eccentric cam 91. Since the grill 12 is pivotally supported around the swinging shaft 41, when the roller 57 of the swinging arm 52 is urged to the left side, the left end side rises around the swinging shaft 41, and The right end side goes down. When the rotation angle θ = 60 °, the swing angle ψ = + 8 °.

  Furthermore, when the rotating shaft 70 rotates, the distance from the rotating shaft 70 to the roller 57 of the swing arm 52 further increases. As shown in FIG. 10, when the rotation angle θ is 95 °, the rotation shaft 70, the center P, the point K, and the roller 57 are positioned on a straight line. At this time, since the distance from the rotating shaft 70 to the roller 57 is the maximum, the left end of the grill net 12 rises most around the swing shaft 41, and the maximum swing angle ψ = + 9 °.

  Thereafter, when the point K of the eccentric cam 91 passes the roller 57 of the swing arm 52, the swing direction of the grill 12 is reversed. The distance from the rotary shaft 70 to the roller 57 of the swing arm 52 begins to gradually decrease, and the distance from the rotary shaft 70 to the roller 56 of the swing arm 51 begins to increase gradually. At this time, the right end side of the grill 12 rises and the left end side starts to fall around the swing shaft 41. As shown in FIG. 11, when the rotation angle θ = 150 °, the swing angle ψ = + 5 °.

  As shown in FIG. 12, when the rotation angle θ = 180 °, the point K is located directly above, the distance from the rotation shaft 70 to the roller 56 of the swing arm 51, and the rotation shaft 70 to the swing arm 52. The distance to the roller 57 is the same. At this time, since the swing angle ψ = 0 °, the grill 12 returns to the horizontal state.

  Next, when the rotating shaft 70 further rotates from the state of FIG. 12, the point K gradually approaches the swing arm 51 side as shown in FIG. Therefore, the distance from the rotating shaft 70 to the roller 58 of the swing arm 52 gradually increases. Since the position of the rotating shaft 70 does not change, the roller 58 of the swing arm 51 is urged rightward by the peripheral side surface of the eccentric cam 91. Since the grill 12 is pivotally supported around the swing shaft 41, when the roller 56 of the swing arm 51 is urged to the right, the grill 12 rises to the right end with the swing shaft 41 as the center. At the same time, the left end side goes down. When the rotation angle θ = 210 °, the swing angle ψ = −4 °.

  Furthermore, the distance from the rotating shaft 70 to the roller 56 of the swing arm 51 further increases. As shown in FIG. 14, when the rotation angle θ = 265 °, the rotation shaft 70, the center P, the point K, and the roller 56 are positioned on a straight line. At this time, since the distance from the rotating shaft 70 to the roller 56 is the maximum, the grilling net 12 rises most on the right end side around the swing shaft 41, and the maximum swing angle ψ = −9 °.

  Thereafter, since the point K of the eccentric cam 91 passes the roller 56 of the swing arm 51, the distance from the rotary shaft 70 to the roller 56 of the swing arm 51 gradually decreases. On the other hand, the distance from the rotating shaft 70 to the roller 57 of the swing arm 52 gradually increases. Accordingly, the swinging direction of the grill 12 is reversed again, and the left end side of the grill 12 rises and the right end side starts to fall. As shown in FIG. 15, when the rotation angle θ = 330 °, the swing angle ψ = −5 °.

  Thus, when the rotation angle θ = 360 °, as shown in FIG. 8, the point K returns to the lowest position, the distance from the rotation shaft 70 to the roller 56 of the swing arm 51, and the swing arm 52 from the swing shaft 70. The distance to the roller 57 is the same. At this time, since the swing angle ψ = 0 °, the grill 12 returns to the horizontal state.

  Here, regarding the eccentric operation of the eccentric cam 91, the distance between the point K of the eccentric cam 91 and the tip of the swing arm 52 decreases, and the distance between the tip of the swing arm 52 and the rotary shaft 70 increases. Accordingly, the operation in which the peripheral side surface of the eccentric cam 91 urges the roller 57 of the swing arm 52 to the left is referred to as a “first eccentric operation”, and the distance between the point K of the eccentric cam 91 and the tip of the swing arm 53. The operation in which the peripheral side surface of the eccentric cam 91 urges the roller 56 of the oscillating arm 51 to the left side as the distance between the tip of the oscillating arm 51 and the rotary shaft 70 increases as the distance decreases. In the case of “eccentric operation”, the eccentric cam 91 alternately repeats the first eccentric operation and the second eccentric operation, whereby the grill 12 continuously swings.

  Thus, during heating in the “double-sided baking mode”, as shown in FIG. 16, the swing angle ψ of the grill 12 is −9 ° to +9 with the rotation angle θ of the rotary shaft 70. Repeatedly increase / decrease within the range of °. That is, since the grill 12 swings within a range of −9 ° to + 9 °, the front and back of the object to be cooked can be baked evenly. As described above, since the grill 12 can be swung only by rotating the drive shaft 150 of the motor 95 in one direction, it is not necessary to control the rotation direction of the motor 95. In addition, since the structure for transmitting the power of the motor 95 to the rotary shaft 70 is compact, the motor 95 can be installed in a narrow appliance on the table stove 1. Furthermore, since the rotational force of the drive shaft 150 of the motor 95 can be satisfactorily transmitted to the rotary shaft 70 via the rotary bearing body 101, the grill net 12 can be smoothly swung.

  In addition, when the cooking object on the grill 12 is baked in the grill warehouse 15 and the operation switch 7 is pressed again by the user, the grill burners 31 and 32 are extinguished and power is supplied to the motor 95 at the same time. Is interrupted, the swing of the grill 12 stops.

  In the above description, the wire mesh swing support mechanism 35 shown in FIG. 3 corresponds to the “support means” of the present invention, the support frame 42 shown in FIG. 4 corresponds to the “support body” of the present invention, and the swing arm 51. , 52 (53, 54) correspond to “a pair of driven node members” of the present invention.

  As described above, in the table stove 1 of the present embodiment, the tray 13 is provided so as to be able to be taken in and out of the grill warehouse 15. The tray 13 is provided with a grilling net swinging support mechanism 35 that supports the grilling net 12 in a swingable manner. The grill mesh swing support mechanism 35 supports the rotary shaft 70 connected to the rotary bearing body 101 of the rotary bearing unit 100 and the grill net 12, and swings the grill net 12 by receiving the rotation of the rotary shaft 70. And a support unit 40.

  The support unit 40 includes a support frame 42 that supports the grill 12 and a swing shaft 41 that swings the support frame 42. A pair of swing arms 51 and 52 are provided on the front frame portion 47 of the support unit 40. The front frame portion 47 is provided with a pair of swing arms 51 and 52. A pair of swing arms 53 and 54 are also provided at the lower portion of the rear frame portion 48. An eccentric cam 91 provided on the rotary shaft 70 is disposed between the respective distal ends of the swing arms 51 and 52. An eccentric cam 92 provided on the rotary shaft 70 is disposed between the respective distal ends of the swing arms 53 and 54.

  When the rotating shaft 70 connected to the rotating bearing body 101 is rotated in one direction by the drive of the motor 95, the eccentric cams 91 and 92 cause the swinging arms 51, 52, 53, and 54 to be alternately attached in the left-right direction. Be forced. Since the grill 12 is pivotally supported by the swing shaft 41, the grill 12 swings smoothly and continuously around the swing shaft 41. In this way, by using the eccentric cams 91 and 92, the grill 12 can be swung with a compact configuration. Furthermore, since the grill net 12 can be swung only by rotating the motor 95 in one direction, complicated control of the motor 95 becomes unnecessary. Therefore, the grill net 12 can be easily swung.

  In addition, this invention is not limited to the said embodiment, A various change is possible. For example, in the above embodiment, the eccentric cam is used to convert the rotational force of the rotating shaft 70 into the swinging motion of the support frame 42, but the cam shape is not limited to this, and the distance from the rotation center to the peripheral side surface May be non-uniform.

  Moreover, in the said embodiment, although the two eccentric cams 91 and 92 are provided in the rotating shaft 70, one piece may be sufficient and it is good to provide more preferably. By providing a plurality of eccentric cams, the support frame 42 can be swung in a balanced manner. When a plurality of cams are provided, the phases of the cams must be aligned.

  Moreover, in the said embodiment, although a pair of fitting pieces 74 and 75 are provided in the rotating shaft 70, one may be sufficient, Preferably it is good to provide multiple. In the case of providing a plurality, it is preferable to provide rotational symmetry with respect to the center of the rotation shaft 70.
