The present invention has achieved the object of suppressing the influence of the shock absorber on the storage space by providing a direct-acting damper on the legs for installing the storage.

As shown in the figure, the door shock absorber 3 is a device that contacts the opening edge of the storage 5 to close the opening and is rotatably supported with respect to the storage 5 to buffer the swinging door 9 that can open and close the opening. It is. This door buffer device 3 includes a leg part 11 on which the storage compartment 5 is installed, a mounting part 17 provided on the leg part 11, a direct-acting damper 15 attached to the mounting part 17, and a linear damper 15 provided on the swinging door 9. The door 9 includes a contact portion 13b that comes into contact with the direct-acting damper 15 to provide a buffer when the door 9 performs a closing operation.

The swing door 9 can be made of any material, shape, and structure. A part of the hinged door 9 may be formed of a glass plate or the like. The swing door 9 may be biased by a spring or the like in the direction of closing the opening.

The housing 5 is for heating devices such as toaster ovens, microwave ovens, microwave ovens, etc. with heating chambers partitioned inside, and is also for cooling devices such as refrigerators, freezers, etc., or devices that do not require heating or cooling of safes, furniture, etc. Is possible.

The leg portion 11 may have any material, shape, structure, mounting structure for the storage 5, etc., as long as it can accommodate the storage 5 and be provided with the direct-acting damper 15 for buffering.

The mounting portion 17 only needs to be provided on the leg portion 11, and the mounting structure of the direct-acting damper 15 is arbitrary. That is, in addition to the mounting hole 17, the mounting portion 17 can adopt a form that allows the direct-acting damper 15 to be mounted, such as a mounting groove or a mounting flange.

The direct-acting damper 15 may be attached to the attaching part 17 in any manner, and the direct-acting damper 15 may be attached to the attaching part 17 later, or the direct-acting damper 15 may be integrally assembled to the attaching part 17.

The direct-acting damper 15 can be realized by an appropriate direct-acting damper such as an air damper or an oil damper.

The direct-acting damper 15 includes a cylinder 33 and a piston rod 35, and the piston rod 35 or the cylinder 33 directly contacts the contact portion 13b of the swing door 9, or indirectly contacts the contact portion 13b of the swing door 9 through a cap 37 or the like. That's fine.

When the swing door 9 performs a closing operation, an idle running section may be provided in which the swing door 9 rotates without the linear motion damper 15 working until the contact portion 13b of the swing door 9 contacts the translation damper 15.

In the idle running section of the swing door 9, the swing door 9 may be realized in a form in which it freely rotates and performs the closing operation, or in a form in which it receives a biasing force from an elastic member such as a tension spring and performs its closing action.

The contact portion 13b only needs to be able to come into contact with the direct-acting damper 15 to provide a buffer when the swing door 9 performs a closing operation, and can be used for the main body of the swing door 9 or the arm portion 13 for rotationally supporting the swing door 9. be prepared for.

The mounting part 17 is a mounting hole into which the cylinder 33 is fitted, and the mounting hole 17 has a penetration part 39 penetrating to the installation surface side of the leg part 11 and a closing member 41 detachably attached to the penetration part 39. You may prepare.

The opening of the storage 5 may be provided with a frame 7 against which the hinged door 9 is brought into contact. In this case, the cylinder 33 may be partially opposed to the edge of the frame 7 in the translational direction. The frame 7 is formed of a metal plate with a certain thickness, but as long as it can be attached to the opening edge of the storage 5, the material, shape, etc. are free depending on the function of the storage 5. . It is preferable that the frame portion 7 is set so as not to interfere with the linear motion direction of the cylinder 33 within its thickness.

The direct-acting damper 15 attached to the mounting portion 17 may have a configuration in which the piston rod 35 contacts the contact portion 13b of the swing door 9. The piston rod 35 may be provided with a cap 37 and may be in contact with the contact portion 13b of the swing door 9 via the cap 37.

The direct-acting damper 15 may be attached to the mounting portion 17 in an inclined manner, and the piston rod 35 may be inclined toward the rotation center C of the swing door 9 toward the housing 5 side. The inclination of the direct-acting damper 15 suppresses the formation of an angular deviation between the operating direction of the direct-acting damper 15 and the direction in which the load from the swinging door 9 is applied when the swinging door 9 comes into contact with the swinging damper 15 . Therefore, the inclination angle of the direct-acting damper 15 can be set freely as long as the deflection angle can be suppressed.

The rotation center C of the swing door 9 may be set to correspond to the height of the piston rod 35 in the extended state.

The height of the center of rotation C of the swing door 9 is between the operating direction of the direct-acting damper 15 and the direction of load application from the swing door 9 when the swing door 9 contacts the direct-acting damper 15 at the contact portion 13b. This suppresses the formation of a declination angle. Therefore, the height of the center of rotation C can be set freely as long as the deflection angle can be suppressed.

The attachment portion 17 may be the attachment hole 17, and the cylinder 33 may be configured by the attachment hole 17. A lining material or the like may be provided in the attachment hole 17.

At least one of the swing door 9 and the direct-acting damper 15 may include a curved surface 45 that makes contact.

The setting of the curved surface 45 is to suppress the formation of an angular deviation between the operating direction of the direct-acting damper 15 and the direction of load application from the swingable door 9 when the swingable door 9 abuts against the direct-acting damper 15. Therefore, as long as the deflection angle can be suppressed, the shape, curvature, etc. of the curved surface can be set freely.

The leg portion 11 may be a door shock absorber attachment that includes a direct-acting damper 15 and can be retrofitted to the storage compartment 5.

The structure of the leg portion 11 that can be added later is free. The leg portion 11 can be attached later by screwing, by using a concave-convex fitting part, or by using a concave-convex fitting part and screwing. This retrofitting is not necessarily limited to a removable one, but can also be realized by a form of retrofitting by adhesion.

Preferably, the leg portion 11 can be used as a door shock absorbing device by supporting the direct-acting damper 15 afterward on the mounting portion 17.

The device 1 with a buffer door equipped with the door buffer device 3 is realized as a toaster oven in which the housing 5 partitions a heating chamber inside, but it can be used for heating microwave ovens, microwave ovens, etc., for cooling refrigerators, freezers, etc. It can also be realized as a form for room temperature use.

[Equipment with buffer door]
FIG. 1 is a sectional view showing a part of a toaster oven equipped with a buffer device according to a first embodiment of the present invention. FIG. 2 is an enlarged cross-sectional view of a part of the toaster oven shown in FIG. FIG. 3 is a perspective view of the leg of the toaster oven of FIG. 1. Note that FIGS. 1 and 2 show a part of the toaster oven, including the legs, a storage compartment, and a part of the swing door.

As shown in FIGS. 1 and 2, a toaster oven 1 is a device with a buffer door to which the door buffer device 3 of Example 1 is applied. The toaster oven 1 is equipped with a door shock absorber 3.

The toaster oven 1 includes a door shock absorber 3, a housing 5, a swing door 9, and a leg portion 11. The housing 5 is for heating and has a heating chamber (not shown) defined therein. This storage 5 has a box shape with an opening (not shown) on the front side, and the edge of the opening of the storage 5 is provided with a metal frame 7. The frame portion 7 serves as a portion against which the swing door 9 is brought into contact at the opening edge of the storage 5.

The hinged door 9 has a predetermined thickness at the abutting portion, and has arm portions 13 at the lower portions on both the left and right sides. Left and right means the left and right sides when looking at the toaster oven 1 from the front, and lower part means the lower part (the lower side in the installation direction of the toaster oven 1) which is the installation side of the toaster oven 1 (the side on which the toaster oven 1 is installed). do.

One side of the swinging door 9 in the door thickness direction contacts the frame 7 at the opening edge of the storage 5 to close the opening. The arm portion 13 of the swing door 9 is rotatably supported on the installation side of the storage 5 on the other side in the door thickness direction. The hinged door 9 is supported axially at a rotation center C by a bracket (not shown) set on the leg portion 11 side. The swing door 9 opens and closes the opening of the storage 5 by rotating around a rotation center C.

The rotation of the swing door 9 is guided by a stay (not shown) disposed between the upper and lower intermediate parts of the swing door 9 and the storage 5 side, and is biased by a tension spring in the direction of closing the opening. The swinging door 9 is biased so that the swinging door 9 has a dead center in the middle of rotation. For example, when the opening angle θ=35° is exceeded, the biasing force of the tension spring is reversed and the biasing force acts in the direction to open the swing door 9, and the open state is maintained at the opening angle θ set by a stopper or the like.

The left and right arm portions 13 are each formed in an arc shape with the other side in the door thickness direction at the end on the installation side centered on the rotation center C. This arcuate shape allows the hinged door 9 to rotate smoothly with respect to the leg portions 11.

The arm portion 13 includes an end slope 13a and an abutment portion 13b at the end on the installation side. The end slope 13a continues in an arc shape and reaches an abutting portion 13b on one side in the door thickness direction.

The end slope 13a is inclined so as to rise from the other side to the one side in the door thickness direction of the hinged door 9. Thereby, the rotation center C of the hinged door 9 is set lower than the contact portion 13b in the vertical direction.

When the swinging door 9 performs a closing operation, the direct-acting damper 15 does not work from the time when the opening angle θ becomes less than 35° due to passing over the dead center until the contact portion 13b abuts the direct-acting damper 15. This rotation angle α of the swing door 9 corresponds to an idle running section in which the translation damper 15 does not work and the swing door 9 rotates in the closing direction relative to the opening due to the tensile force of the tension spring. Note that the imaginary section can be easily adjusted by adjusting the amount of protrusion of the direct-acting damper 15 from the mounting hole 17, which will be described later.

The abutting portion 13b is formed of an abutting surface that is perpendicular to the other surface of the opening/closing door 9 in the door thickness direction (the surface that closes the opening of the storage 5). The contact surface 13b has an angular setting that eliminates or suppresses the deflection angle with respect to the orthogonal damper 15 when the contact surface 13b contacts the direct-acting damper 15.

The door shock absorbing device 3 includes a leg portion 11, a mounting hole 17, a direct-acting damper 15, and the above-mentioned contact portion 13b, and buffers the swing door 9 that can open and close the opening of the storage 5.

As shown in FIGS. 1 to 3, the leg portion 11 is made of resin or the like, and is attached to the installation side of the storage 5. A pair of leg portions 11 are arranged on both left and right sides of the opening of the storage 5. One of the left and right leg portions 11 may be formed of a leg portion without the direct-acting damper 15, a simple-shaped pedestal, or the like. The rear left and right sides of the housing 5 may be constructed of legs without the direct-acting damper 15, a simple-shaped pedestal, or the like.

At least one of the leg portions 11 on the left and right sides of the opening of the housing 5 is provided with a mounting hole 17 as a mounting portion for the direct-acting damper 15. The attachment hole 17 is a bottomed hole formed in the receiving surface 18. The cylinder of the direct-acting damper 15 fits into the mounting hole 17 so as to be slidable in the axial direction. Adjacent to the attachment hole 17, a relief portion 31 is formed in the leg portion 11. The relief portion 31 forms a step with respect to the receiving surface 18 .

The leg 11 has a seat 19 formed on the rear side of the receiving surface 18, and a rectangular mating protrusion 21 protrudes from the seat 19. A screw hole 23 is formed in the mating protrusion 21 of the seat 19. Note that the mating protrusion 21 and the screw hole 23 are not shown in Figures 1 and 2. The screw hole 23 penetrates from the installation surface side of the leg 11 to the mating protrusion 21.

Further, a leg slope 25 is formed on the leg 11. The leg slope 25 and the receiving surface 18 correspond to the end slope 13a and the contact surface 13b of the swing door 9. The end slope 13a and abutment surface 13b of the hinged door 9 with its opening closed should preferably have a small gap with respect to the leg slope 25 and the receiving surface 18. However, the end slope 13a and the contact surface 13b of the hinged door 9 with the opening closed may be in close contact with the leg slope 25 and the receiving surface 18.

A bracket insertion portion 27 is formed on the leg slope 25. A fastening hole 29 for fastening a bracket is formed in the leg portion 11 and communicates with the insertion portion 27 .

The direct-acting damper 15 is attached to the attachment hole 17 of the leg portion 11. The direct-acting damper 15 comes into contact with the abutment surface 13b of the swing door 9 when the swing door 9 is closed, and buffers the swing door 9.

The direct-acting damper 15 is an air damper, a hydraulic damper, or the like, and includes a cylinder 33 and a piston rod 35. The direct-acting damper 15 of this embodiment is inserted into the mounting hole 17 with the piston rod 35 side facing down, and the cap 37 at the tip is butted against the bottom of the mounting hole 17. The cylinder 33 is loosely fitted into the mounting hole 17 and has a bottom protruding outside the mounting hole 17 .

In the leg portion 11 having such a configuration, the fitting protrusion 21 is fitted into a fitting recess (not shown) formed at the bottom of the toaster oven 1. In this state, the leg portion 11 is fastened and fixed to the toaster oven 1 with a screw through the screw hole 23.

A bracket is inserted into the insertion part 27, and the bracket is fastened and fixed to the leg part 11 with a screw through the fastening hole 29. An arm portion 13 of the swing door 9 is rotatably supported at the tip of this bracket at a rotation center C.

In the leg portion 11 , the leg slope 25 side in the door thickness direction including the attachment portion of the direct-acting damper 15 protrudes forward from the bottom of the toaster oven 1 . In this embodiment, the direct-acting damper 15 is arranged to be oriented vertically with respect to the toaster oven 1 which is installed in a horizontal state. A portion of the translational damper 15 is disposed opposite to the edge of the frame 7 with a gap in the translational direction.

The cylinder 33 of the direct-acting damper 15 loosely fitted into the mounting hole 17 interferes with the frame portion 7 in the direction of removal from the mounting hole 17. Therefore, it is possible to prevent the direct-acting damper 15 from falling off or being intentionally removed. Note that the frame portion 7 can also be omitted.

The leg portion 11 can be configured as a door shock absorber attachment that can be retrofitted to the toaster oven 1 equipped with the linear damper 15 and the storage compartment 5.

Therefore, the legs 11 can be replaced depending on the grade of the toaster oven 1, or the user can easily replace the legs 11 as a door shock absorber attachment.

By configuring the leg portion 11 to include a mounting hole 17 that can support the direct-acting damper 15 afterward, a door shock absorber attachment can be easily formed. The leg portion 11 can also be used without the direct-acting damper 15.

[Effect]
The swing door 9 can be opened and closed by rotating the arm portion 13 around the rotation center C.

That is, as the swinging door 9 rotates, one side of the swinging door 9 in the door thickness direction comes into contact with the frame 7 at the opening edge of the storage 5 to open and close the opening.

When opening and closing the swing door 9, the tension force of the tension spring exceeds the dead center at the opening angle θ = 35°, and when the opening angle θ = 35° is exceeded, the swing door 9 does not close due to the tension spring. When the opening angle θ is less than 35°, a closing operation is performed by the tensile force of the tension spring.

When the opening angle θ is less than 35° and the rotary motion is performed in the idle running section of the rotation angle α, the contact surface 13b of the arm portion 13 comes into contact with the cylinder 33 of the direct-acting damper 15. When the closing operation of the swing door 9 further progresses due to the tension force of the tension spring, the cylinder 33 is pushed down into the attachment hole 17.

At this time, since the piston rod 35 is received at the bottom of the mounting hole 17, the direct-acting damper 15 contracts in response to the depression of the cylinder 33, producing a damping effect. Therefore, the swinging door 9 proceeds with its closing operation while being buffered by the damping action of the direct-acting damper 15. Thereafter, the swing door 9 can come into contact with the frame 7 at the opening edge of the storage 5 to quietly close the opening.

Therefore, the unpleasant sound when the swing door 9 closes can be suppressed, and a sense of luxury can be created.

Moreover, since the impact when the swing door 9 closes can be suppressed, it is possible to suppress the displacement of the toaster oven 1 main body with respect to the installation surface.

When the direct-acting damper 15 generates a damping action, the cylinder 33 is received by the wall surface of the mounting hole 17, so the direct-acting damper 15 is free from unreasonable forces acting on the direct-acting damper 15 due to the deflection angle between the contact surface 13a and the cylinder 33. The force can be greatly suppressed and durability can be improved. Furthermore, the frictional force between the cylinder 33 of the direct-acting damper 15 and the wall surface of the mounting hole 17 can also be used for the damping effect.

Furthermore, in this embodiment, since the mounting hole 17 is closed by the cylinder 33 of the direct-acting damper 15, the space between the cylinder 33 and the piston rod 35 is not exposed to the outside, and foreign matter such as breadcrumbs can be easily removed. Intrusion into the dynamic damper 15 etc. can be suppressed.

Since the direct-acting damper 15 is attached to the leg portion 11 outside the storage 5, it is not easily affected by the heating inside the storage 5, and its durability can be improved. Further, the storage space of the storage 5 is not affected by the direct-acting damper 15 and the mounting portion.

Since the direct-acting damper 15 can be handled together with the legs 11 and assembled into the toaster oven 1, assembly becomes easy.

FIG. 4 is a graph of closing speed versus opening angle of the toaster oven 1. FIG. 5 is a graph of door opening angle versus door closing time of the toaster oven 1.

The damping action by the direct-acting damper 15 is as shown in FIG.

In FIG. 4, line segment A shows the case where the direct-acting damper 15 is present and the swinging door 9 is closed using only spring force. Line segment B shows the case where the door 9 is closed by adding manual acceleration to the spring force with the direct-acting damper 15. Line segment C shows the case where the door 9 is closed by applying stronger manual acceleration to the spring force with the direct-acting damper 15. Line segment D shows the case where the swing door 9 is closed only by the spring force without the direct-acting damper 15. Line segment E shows the case where the door 9 is closed without the direct-acting damper 15 by adding manual acceleration to the spring force.

When the swing door 9 exceeds the opening angle θ=35°, the spring force will not close the swing door 9, so the closing speed is zero.

When the opening angle θ becomes less than 35°, the closing speed of the swing door 9 increases linearly until the opening angle θ=15° at which the direct-acting damper 15 starts working.

In the case of line segment A, which performs the closing action using only spring force, in the case of line segment B, which performs the closing action by adding manual acceleration to the spring force, or by adding stronger manual acceleration to the spring force, the closing action is performed. The closing speed of the swing door 9 is slower than in the case of the line segment C that causes the movement.

The direct-acting damper 15 starts working at the opening angle θ=15° of the swing door 9, and the closing speed is rapidly reduced until the opening angle θ=0° at which the opening of the storage 5 is closed.

Note that if there is no direct-acting damper 15, there is no deceleration of the closing speed as shown in line segments D and E.

Next, the relationship between the door closing time under damping by the linear damper 15 is as shown in FIG.

When the swinging door 9 is closed between the opening angle θ=0 and 35°, the door closing time changes as shown in the figure. Even when closing from an opening angle θ=35°, the door closing time is about 3 seconds.

In the first embodiment, since the free running section is set at the rotation angle α, the swing door 9 can smoothly close the free running section by the tensile force of the tension spring, and then the direct-acting damper 15 is activated. be able to. Therefore, the swing door 9 can be smoothly closed in a short time of 3 seconds while suppressing the impact of the swing door 9.

The door shock absorbing device 3 of the second embodiment includes a penetration portion 39 and a closing member 41 in the attachment hole 17 of the leg portion 11 .

In the present embodiment, the penetrating portion 39 is a screw hole formed at the bottom of the mounting hole 17, and penetrates to the installation surface side of the leg portion 11. The diameter of the penetrating portion 39 is set to be smaller than that of the attachment hole 17.

A counterbore portion 43 is formed on the bottom surface of the leg portion 11, including the portion of the through portion 39.

The closing member 41 is a removable plug that is screwed into the penetrating portion 39 to close the penetrating portion 39 .

Therefore, even if liquid such as oil or moisture accumulates in the attachment hole 17 from around the cylinder 33, it can be easily discharged by removing the closing member 41. Note that the closing member 41 can also be a valve or the like.

FIGS. 8 and 9 show a part of a toaster oven including a leg part, a storage compartment, and a part of a swing door.

The door shock absorber 3 of the third embodiment has a structure in which the cap 37 of the piston rod 35 abuts against the contact surface 13b of the swing door 9 in the direct-acting damper 15 attached to the mounting hole 17.

In this case, in the direct-acting damper 15, the mounting hole 17 is inclined toward the rotation center C toward the storage 5. The cylinder 33 fits into the mounting hole 17, and the direct-acting damper 15 is inclined according to the mounting hole 17. The piston rod 35 of the direct-acting damper 15 is inclined toward the rotation center C similarly to the direct-acting damper 15.

Therefore, the deflection angle of the piston rod 35 with respect to the contact surface 13b of the arm portion 13 can be suppressed, and unreasonable force on the piston rod 35 can be suppressed, and the durability of the door shock absorber 3 can be improved.

In addition, the third embodiment can also provide the same effects as the first embodiment.
