Background Art

[0002] As a door buffer device, for example, there is a buffer device described in Patent Document 1. This buffer device is configured to buffer the door of a high-frequency heater and is configured as an air damper including a piston and a cylinder attached inside the heating chamber.

[0003] When the door is closed by such a buffer device, the door is received by the piston lever, and the door can be buffered by receiving the reaction force of the compressed air of the piston.

[0004] However, since the buffer device of Patent Document 1 is attached inside the heating chamber, there is a problem that the accommodation space of the heating chamber is affected by the buffer device.

[0005] Such a problem occurs not only in the door of a high-frequency heater but also in the doors of various storage cabinets such as a refrigerator.

[Modes for carrying out the invention]

[0017] The present invention achieves the objective of suppressing the influence of the shock absorber on the storage space by providing a linear damper on the legs for installing the storage compartment.

[0018] As shown in the figure, the door buffer device 3 abuts against the opening edge of the storage compartment 5 to close the opening and buffers the hinged door 9 which is rotatably supported relative to the storage compartment 5 and can open and close the opening. The door buffer device 3 comprises a leg portion 11 on which the storage compartment 5 is installed, a mounting portion 17 provided on the leg portion 11, a linear damper 15 attached to the mounting portion 17, and a contact portion 13b provided on the hinged door 9 which abuts against the linear damper 15 to buffer the movement when the hinged door 9 is closing.

[0019] The hinged door 9 may be made of any material, shape, or structure. Part of the hinged door 9 may be made of glass or the like. The hinged door 9 may also be biased by a spring or the like in the direction of closing the opening.

[0020] Storage compartment 5 can be used for heating, such as by partitioning the heating chamber inside an oven toaster, microwave oven, or oven range, as well as for cooling, such as a refrigerator or freezer, or for items that do not require heating or cooling, such as a safe or furniture.

[0021] The leg portion 11 only needs to be able to accommodate the storage compartment 5 and be equipped with a linear damper 15 for cushioning, and its material, shape, structure, and mounting structure to the storage compartment 5 are all flexible.

[0022] The mounting portion 17 only needs to be provided on the leg portion 11, and the mounting structure of the linear damper 15 is flexible. In other words, the mounting portion 17 can be configured in a way that allows for the mounting of the linear damper 15, such as by having a mounting hole 17, a mounting groove, or a mounting flange.

[0023] The mounting configuration of the linear damper 15 to the mounting portion 17 is arbitrary; the linear damper 15 may be retrofitted to the mounting portion 17, or the linear damper 15 may be assembled integrally with the mounting portion 17.

[0024] The linear damper 15 can be implemented using an appropriate linear damper such as an air damper or an oil damper.

[0025] The linear damper 15 comprises a cylinder 33 and a piston rod 35, and the piston rod 35 or cylinder 33 may directly contact the contact portion 13b of the opening door 9, or indirectly contact it via a cap 37 or the like.

[0026] The hinged door 9 may have a free-running section in which it rotates without the linear damper 15 acting until the contact portion 13b of the hinged door 9 contacts the linear damper 15 when the hinged door 9 is closing.

[0027] During the free-running section of the hinged door 9, the hinged door 9 may be implemented in a form that rotates freely to perform the closing operation, or in a form that performs the closing operation by receiving a biasing force from an elastic member such as a tension spring.

[0028] The contact portion 13b only needs to be able to contact the linear damper 15 and provide cushioning when the hinged door 9 is closing, and can be provided on the main body of the hinged door 9 or on the arm portion 13 for supporting the rotation of the hinged door 9.

[0029] The mounting portion 17 is a mounting hole into which the cylinder 33 is fitted, and the mounting hole 17 may include a through portion 39 that penetrates to the mounting surface side of the leg portion 11 and a closing member 41 that is detachably attached to the through portion 39.

[0030] The opening of the storage compartment 5 may be provided with a frame portion 7 upon which the hinged door 9 abuts. In this case, the cylinder 33 may be positioned partially opposite the edge of the frame portion 7 in the linear direction. The frame portion 7 is formed from a metal plate of a certain thickness, but the material, shape, etc., are free as long as it is attached to the opening edge of the storage compartment 5, depending on the function of the storage compartment 5. It is preferable that the frame portion 7 is set so as not to interfere with the linear direction of the cylinder 33 within its thickness.

[0031] The linear damper 15 attached to the mounting portion 17 may be configured such that the piston rod 35 abuts against the contact portion 13b of the hinged door 9. The piston rod 35 may also be equipped with a cap 37, and the piston rod 35 abuts against the contact portion 13b of the hinged door 9 via the cap 37.

[0032] The linear damper 15 is mounted at an angle to the mounting portion 17, and the piston rod 35 may be tilted toward the rotation center C of the hinged door 9 toward the storage compartment 5. The tilt of the linear damper 15 suppresses the formation of an angle of deviation between the operating direction of the linear damper 15 and the direction of load application from the hinged door 9 when the hinged door 9 makes contact. Therefore, the tilt angle of the linear damper 15 can be freely set as long as the angle of deviation is suppressed.

[0033] The hinged door 9 may be set so that its rotation center C corresponds to the height of the piston rod 35 in its extended state.

[0034] The height of the rotation center C of the hinged door 9 is set to suppress the formation of an angle of deviation between the operating direction of the linear damper 15 and the direction of load application from the hinged door 9 when the hinged door 9 contacts the linear damper 15 at the contact portion 13b. Therefore, the height of the rotation center C can be freely set as long as the angle of deviation is suppressed.

[0035] The mounting portion 17 is a mounting hole 17, and the cylinder 33 may also be composed of the mounting hole 17. A lining material or the like may be set in the mounting hole 17.

[0036] At least one of the hinged door 9 or the linear damper 15 may be provided with a curved surface 45 for contact.

[0037] The curved surface 45 is designed to suppress the formation of an angle between the operating direction of the linear damper 15 and the direction of the load applied from the hinged door 9 when the hinged door 9 comes into contact with the linear damper 15. Therefore, as long as the angle of deviation can be suppressed, the shape, curvature, etc., of the curved surface can be freely set.

[0038] The leg portion 11 may also be a door buffer attachment that can be retrofitted to the storage compartment 5 and is equipped with a linear damper 15.

[0039] The structure for attaching the legs 11 is flexible. The legs 11 can be attached by screw fastening, by interlocking parts, or by interlocking parts and screw fastening. This attachment is not necessarily limited to removable parts; it can also be achieved by adhesive fastening, etc.

[0040] It is preferable that the leg portion 11 be used as a door buffer device by retrofitting and supporting a linear damper 15 to the mounting portion 17.

[0041] The device 1 with a buffer door equipped with a door buffer device 3 is implemented as an oven toaster in which the storage compartment 5 partitions the heating chamber inside, but it can also be implemented in forms such as a microwave oven or oven range for heating, a refrigerator or freezer for cooling, or a room temperature appliance. [Examples]

[0042] [Equipment with buffer doors] Figure 1 is a cross-sectional view showing a part of an oven toaster equipped with a buffer device according to Embodiment 1 of the present invention. Figure 2 is a cross-sectional view showing an enlarged portion of the oven toaster in Figure 1. Figure 3 is a perspective view of the legs of the oven toaster in Figure 1. Figures 1 and 2 show a part of the oven toaster, including the storage compartment and a portion of the hinged door, centered on the legs.

[0043] As shown in Figures 1 and 2, the appliance with a door buffer that incorporates the door buffer device 3 of Example 1 is an oven toaster 1. The oven toaster 1 is equipped with the door buffer device 3.

[0044] The oven toaster 1 includes a door buffer device 3, a storage compartment 5, a hinged door 9, and legs 11. The storage compartment 5 is for heating and contains a heating chamber (not shown) inside. The storage compartment 5 is box-shaped with an opening (not shown) on its front, and the opening edge of the storage compartment 5 is fitted with a metal frame 7. The frame 7 is the part of the opening edge of the storage compartment 5 that the hinged door 9 abuts against.

[0045] The hinged door 9 has a predetermined thickness at the contact point and is equipped with arm portions 13 on the lower left and right sides. Left and right refers to the left and right sides when the oven toaster 1 is viewed from the front, and lower refers to the lower side (the side on which the oven toaster 1 is installed) of the oven toaster 1.

[0046] The hinged door 9 closes the opening of the storage compartment 5 by abutting one side in the door thickness direction against the frame portion 7 at the opening edge. The hinged door 9 is rotatably supported on the other side in the door thickness direction towards the installation side of the storage compartment 5. The hinged door 9 is supported axially at the center of rotation C by a bracket (not shown) set on the leg portion 11 side. The hinged door 9 opens and closes the opening of the storage compartment 5 by rotating at the center of rotation C.

[0047] The rotation of the hinged door 9 is guided by a stay (not shown) positioned between the upper and lower middle section of the hinged door 9 and the storage compartment 5, and is biased by a tension spring in the direction of closing the opening. The biasing of the hinged door 9 is performed so that it has a dead point during its rotation. For example, when the opening angle θ exceeds 35°, the biasing force of the tension spring reverses and acts as a biasing force in the direction of opening the hinged door 9, and the open state is maintained at the opening angle θ set by a stopper or the like.

[0048] The left and right arm portions 13 are formed in an arc shape at the installation end, on the side other than the door thickness direction, with the rotation center C as the center. This arc shape is intended to allow the hinged door 9 to rotate smoothly relative to the leg portion 11.

[0049] The arm portion 13 is provided with an end slope 13a and a contact portion 13b at the installation end. The end slope 13a is continuous in an arc shape and extends to the contact portion 13b on one side in the door thickness direction.

[0050] The end slope 13a is inclined to rise from one side to the other in the thickness direction of the hinged door 9. As a result, the rotation center C of the hinged door 9 is set lower than the contact portion 13b in the vertical direction.

[0051] When the hinged door 9 is closing, the linear damper 15 does not operate from the point when the opening angle θ = 35° is exceeded due to passing the dead center until the contact portion 13b contacts the linear damper 15. The rotation angle α of this hinged door 9 is a free-running section in which the hinged door 9 rotates in the closing direction relative to the opening due to the tensile force of the tension spring without the linear damper 15 operating. This free-running section can be easily adjusted by the amount of protrusion from the mounting hole 17 of the linear damper 15, which will be described later.

[0052] The contact portion 13b is formed as a contact surface perpendicular to the other side of the door thickness direction of the opening / closing door 9 (the surface that closes the opening of the storage compartment 5). The contact surface 13b has an angle setting that eliminates or suppresses the deviation angle with respect to the orthogonal damper 15 when it contacts the linear damper 15.

[0053] The door buffer device 3 consists of a leg portion 11, a mounting hole 17, a linear damper 15, and the contact portion 13b, and buffers the swing door 9 that can open and close the opening of the storage compartment 5.

[0054] As shown in Figures 1 to 3, the legs 11 are made of resin or the like and are attached to the installation side of the storage compartment 5. A pair of legs 11 are arranged on both the left and right sides of the opening of the storage compartment 5. One of the legs 11 on each side can be made of a leg without a linear damper 15 or a simple base. The rear left and right sides of the storage compartment 5 can be made of legs without a linear damper 15 or simple bases.

[0055] At least one of the legs 11 on both the left and right sides of the opening of the storage compartment 5 is provided with a mounting hole 17 for a linear damper 15. The mounting hole 17 is formed as a bottomed hole formed in the receiving surface 18. The cylinder of the linear damper 15 is fitted into the mounting hole 17 so as to be axially slidable. Adjacent to the mounting hole 17, a relief portion 31 is formed in the leg 11. The relief portion 31 forms a step relative to the receiving surface 18.

[0056] The leg portion 11 has a seat portion 19 formed on the rear side of the receiving surface 18, and a rectangular fitting projection 21 is provided protruding from the seat portion 19. A screw hole 23 is formed in the fitting projection 21 of the seat portion 19. Note that the fitting projection 21 and the screw hole 23 are not shown in Figures 1 and 2. The screw hole 23 penetrates from the mounting surface side of the leg portion 11 to the fitting projection 21.

[0057] Furthermore, a leg slope 25 is formed on the leg portion 11. The leg slope 25 and the receiving surface 18 correspond to the end slope 13a and the contact surface 13b of the hinged door 9. When the opening of the hinged door 9 is closed, it is preferable that there is a small gap between the end slope 13a and the contact surface 13b and the leg slope 25 and the receiving surface 18. However, when the opening of the hinged door 9 is closed, the end slope 13a and the contact surface 13b may be in close contact with the leg slope 25 and the receiving surface 18.

[0058] A bracket insertion portion 27 is formed on the inclined surface 25 of the leg portion. A fastening hole 29 for fastening the bracket is formed on the leg portion 11 and communicates with the insertion portion 27.

[0059] The linear damper 15 is attached to the mounting hole 17 of the leg portion 11. The linear damper 15 contacts the contact surface 13b of the hinged door 9 when the hinged door 9 closes, thereby cushioning the hinged door 9.

[0060] The linear damper 15 is an air damper or a hydraulic damper, and comprises a cylinder 33 and a piston rod 35. In this embodiment, the linear damper 15 is inserted into the mounting hole 17 with the piston rod 35 side facing downwards, and the cap 37 at the tip abuts against the bottom of the mounting hole 17. The cylinder 33 is loosely fitted into the mounting hole 17, with its bottom protruding outside the mounting hole 17.

[0061] In this configuration, the leg portion 11 has a fitting projection 21 that fits into a fitting recess (not shown) formed on the bottom of the oven toaster 1. In this state, the leg portion 11 is fastened and fixed to the oven toaster 1 by screws via screw holes 23.

[0062] A bracket is inserted into the insertion part 27, and the bracket is fastened and secured to the leg part 11 by screws through the fastening hole 29. The arm part 13 of the hinged door 9 is pivotally supported at the tip of this bracket so as to be rotatable at the rotation center C.

[0063] The leg portion 11, including the mounting portion for the linear damper 15, has a leg inclined surface 25 in the door thickness direction that protrudes forward from the bottom of the oven toaster 1. In this embodiment, the linear damper 15 is positioned perpendicular to the oven toaster 1 when it is installed in a horizontal position. A portion of the linear damper 15 is positioned opposite the edge of the frame portion 7 with a gap in the linear direction.

[0064] The cylinder 33 of the linear damper 15, which is loosely fitted into the mounting hole 17, interferes with the frame 7 in the direction of removal from the mounting hole 17. This prevents the linear damper 15 from falling out or being intentionally removed. The frame 7 can also be omitted.

[0065] Such leg portion 11 can be configured as a door buffer attachment that can be retrofitted to an oven toaster 1 equipped with a linear damper 15 and a storage compartment 5.

[0066] Therefore, the legs 11 can be replaced according to the grade of the oven toaster 1, or the user can easily replace the legs 11 as a door buffer attachment.

[0067] The leg portion 11 is configured to have mounting holes 17 that allow for the retrofitting and support of a linear damper 15, thereby easily forming a door buffer attachment. The leg portion 11 can also be used in a configuration without the linear damper 15.

[0068] [Effects and Effects] The hinged door 9 can be opened and closed by the rotation of the arm portion 13 around the rotation center C.

[0069] In other words, the hinged door 9 rotates so that one side of the hinged door 9 in the thickness direction comes into contact with the frame portion 7 of the opening edge of the storage compartment 5, thereby opening and closing the opening.

[0070] When this hinged door 9 is opened and closed, the dead center of the tension spring's tensile force is exceeded at an opening angle θ = 35°. If the opening angle exceeds θ = 35°, the hinged door 9 will not be closed by the tension spring, and if the opening angle falls below θ = 35°, the door will be closed by the tension spring's tensile force.

[0071] When the opening angle θ = 35° falls below this range and the arm rotates through a free-running section with a rotation angle α, the contact surface 13b of the arm portion 13 comes into contact with the cylinder 33 of the linear damper 15. As the closing motion of the opening door 9 progresses further due to the tensile force of the tension spring, the cylinder 33 is pushed down into the mounting hole 17.

[0072] At this time, the linear damper 15 contracts in response to the downward pressure of the cylinder 33, as the piston rod 35 is supported at the bottom of the mounting hole 17, thereby generating a damping effect. Consequently, the hinged door 9 proceeds to close while being cushioned by the damping effect of the linear damper 15. After that, the hinged door 9 can come into contact with the frame portion 7 at the opening edge of the storage compartment 5 and quietly close the opening.

[0073] Therefore, it is possible to suppress the unpleasant noise when the hinged door 9 closes and create a sense of luxury.

[0074] Furthermore, because the impact when the hinged door 9 closes can be suppressed, the displacement of the oven toaster 1 body relative to the mounting surface can be suppressed.

[0075] In the linear damper 15, when the damping action is generated, the cylinder 33 is supported by the wall surface of the mounting hole 17. Therefore, the excessive force acting on the linear damper 15 due to the angle between the contact surface 13a and the cylinder 33 can be greatly suppressed, thereby improving durability. Furthermore, the frictional force between the cylinder 33 of the linear damper 15 and the wall surface of the mounting hole 17 can also be utilized for the damping action.

[0076] Furthermore, in this embodiment, the mounting hole 17 is closed by the cylinder 33 of the linear damper 15, so the space between the cylinder 33 and the piston rod 35 is not exposed to the outside, which prevents foreign matter such as breadcrumbs from entering the inside of the linear damper 15.

[0077] Since the linear damper 15 is attached to the leg portion 11 outside the storage compartment 5, it is less susceptible to the effects of heating inside the storage compartment 5, thereby improving durability. In addition, the storage space inside the storage compartment 5 is not affected by the linear damper 15 or its mounting portion.

[0078] The linear damper 15 can be handled together with the leg portion 11 and assembled to the oven toaster 1, making assembly easier.

[0079] Figure 4 is a graph showing the closing speed-opening angle of oven toaster 1. Figure 5 is a graph showing the door opening angle-door closing time of oven toaster 1.

[0080] The damping effect of the linear damper 15 is shown in Figure 4.

[0081] In Figure 4, line segment A shows the case where the hinged door 9 is closed using only spring force with the linear damper 15 present. Line segment B shows the case where the hinged door 9 is closed using spring force plus manual acceleration with the linear damper 15 present. Line segment C shows the case where the hinged door 9 is closed using spring force plus stronger manual acceleration with the linear damper 15 present. Line segment D shows the case where the hinged door 9 is closed using only spring force without the linear damper 15 present. Line segment E shows the case where the hinged door 9 is closed using spring force plus manual acceleration without the linear damper 15 present.

[0082] When the opening angle θ exceeds 35°, the spring force will no longer be able to close the hinged door 9, so the closing speed is zero.

[0083] The closing speed of the hinged door 9 increases linearly until the opening angle θ = 15°, at which point the linear damper 15 begins to work when the opening angle θ = 35° falls below that point.

[0084] In the case of line segment A, where the closing action is performed solely by spring force, the closing speed of the open door 9 is slower than in the case of line segment B, where manual acceleration is added to the spring force to perform the closing action, or in the case of line segment C, where stronger manual acceleration is added to the spring force to perform the closing action.

[0085] When the opening angle θ = 15° of the hinged door 9, the linear damper 15 begins to work, and the opening of the storage compartment 5 closes to an opening angle θ = 0°, and the speed is rapidly reduced.

[0086] Furthermore, if the linear damper 15 is absent, there is no reduction in closing speed as shown in line segments D and E.

[0087] Next, the relationship between the door closing time under damping by the linear damper 15 is shown in Figure 5.

[0088] When closing door 9 at an opening angle θ = 0 to 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 approximately 3 seconds.

[0089] In this embodiment 1, a free-running section with a rotation angle α is set, so the hinged door 9 can smoothly close during the free-running section due to the tensile force of the tension spring, and then the linear damper 15 can be activated. As a result, the hinged door 9 can be closed smoothly in a short time of 3 seconds while suppressing the impact. [Examples]

[0090] Figure 6 is a cross-sectional view showing a part of an oven toaster equipped with a buffer device according to Embodiment 2 of the present invention. Figure 7 is a cross-sectional view showing an enlarged portion of the oven toaster in Figure 6. The basic configuration is the same as in Embodiment 1, and the same or corresponding components are denoted by the same reference numerals, and redundant explanations are omitted. Figures 6 and 7 show a part of the oven toaster, including the legs, storage compartment, and a portion of the hinged door.

[0091] The door buffer device 3 of this embodiment 2 is equipped with a through portion 39 and a closing member 41 in the mounting hole 17 of the leg portion 11.

[0092] In this embodiment, the through-hole 39 is a screw hole formed at the bottom of the mounting hole 17 and penetrates to the mounting surface side of the leg portion 11. The diameter of the through-hole 39 is set to be smaller than the diameter of the mounting hole 17.

[0093] A recessed portion 43 is formed on the bottom surface of the leg portion 11, including the portion of the through-hole 39.

[0094] The closing member 41 is a removable plug that screws into the through-hole 39 to close the through-hole 39.

[0095] Therefore, even if liquids such as oil or water accumulate in the mounting hole 17 from around the cylinder 33, they can be easily drained by removing the closing member 41. The closing member 41 can also be a valve or the like.

[0096] Furthermore, the same effects and advantages as in Example 1 can be achieved in Example 2. [Examples]

Figures 8 and 9 are parts of an oven toaster, including the storage compartment and a part of the hinged door, with the legs as the center.

[0098] In this embodiment 3, the door buffer device 3 is configured such that the cap 37 of the piston rod 35 of the linear damper 15 attached to the mounting hole 17 contacts the contact surface 13b of the opening door 9.

[0099] In this case, the linear damper 15 has a mounting hole 17 that is inclined toward the rotation center C toward the storage compartment 5. The cylinder 33 is fitted into this mounting hole 17, and the linear damper 15 is inclined in accordance with the mounting hole 17. The piston rod 35 of the linear damper 15 is inclined toward the rotation center C, similar to the linear damper 15.

[0100] Therefore, the angle of deviation of the piston rod 35 with respect to the contact surface 13b of the arm portion 13 can be suppressed, excessive force on the piston rod 35 can be suppressed, and the durability of the door buffer device 3 can be improved.

[0101] Furthermore, the same effects and advantages as in Example 1 can be achieved in this Example 3 as well. [Examples]

[0103] In this embodiment 4, the door buffer device 3 has a structure in which the rotation center C of the hinged door 9 is set to correspond to the height of the piston rod 35 in its extended state.

[0104] In this embodiment, the rotation center C is set to the same height as the upper surface of the cap 37 of the piston rod 35.

[0105] Therefore, the angle of deviation of the piston rod 35 with respect to the contact surface 13b of the arm portion 13 can be suppressed, excessive force on the piston rod 35 can be suppressed, and durability can be improved.

[0106] Furthermore, the position of the rotation center C only needs to be such that the angular misalignment is suppressed, and it can also be set with a slight vertical displacement relative to the upper surface of the cap 37 of the piston rod 35.

[0107] Furthermore, the same effects and advantages as in Example 1 can be achieved in this Example 4 as well. [Examples]

Figures 12 and 13 show a part of the oven toaster, including the storage compartment and a part of the hinged door, centered on the legs.

[0109] In the door buffer device 3 of this embodiment 5, the linear damper 15 is integrally formed with the leg portion 11.

[0110] In other words, the cylinder 33 of the linear damper 15 is formed by the mounting hole 17. As a result, the linear damper 15 is integrated with the leg portion 11, making assembly and parts management easier.

[0111] Furthermore, the same effects and advantages as in Example 1 can be achieved in this Example 5. [Examples]

[0112] Figure 14 is a cross-sectional view showing a part of an oven toaster equipped with a shock absorber according to Embodiment 6 of the present invention.

Figures 14 and 15 show a part of an oven toaster, including the legs, storage compartment, and a part of the hinged door.

[0113] In this embodiment 6, the door buffer device 3 has a structure in which the cylinder 33 of the linear damper 15 is positioned away from the edge of the frame 7 in the linear direction.

[0114] Therefore, even if a leg portion 11 without a linear damper 15 is attached, the linear damper 15 can be easily added later. Furthermore, the attached linear damper 15 can be easily removed, making repairs and replacements simple. If a linear damper 15 is not provided, the mounting hole 17 can be closed with a cap or the like.

[0115] Furthermore, the same effects and advantages as in Example 1 can be achieved in this Example 6. [Examples]

[0118] The linear damper 15 has a cylinder 33 fitted into a mounting hole 17, with a piston rod 35 protruding outside the mounting hole 17. A curved surface 45 is formed on a cap 37 attached to the upper end of the piston rod 35.

[0119] Therefore, the curved surface 45 suppresses the angle of deviation of the piston rod 35 with respect to the contact surface 13b of the arm portion 13, thereby suppressing excessive force on the piston rod 35 and improving durability.

[0120] Furthermore, the same effects and advantages as in Example 1 can be achieved in this Example 7 as well. [Examples]
