Description

Oven with lifting rack

The present invention relates to an oven to which a lifting structure capable of easily adjusting the height of a shelf installed in a cavity of an oven according to a type of cooking is applied.

An oven is a cooking appliance that cooks food by circulating hot air in a predetermined closed space. Inside the oven, a tray on which food is placed is installed. The height of the shelf is determined in the enclosed space, ie the cavity, depending on what food is to be cooked.

Conventionally, when selecting what foods to cook in the oven, the oven informs the user of the optimal shelf height according to the display. The user adjusts the shelf height of the oven by referring to the information displayed on the display.

The user opens the door, removes the shelf from the cavity, and then manually places the shelf at the optimal height for the desired dish by inserting the shelf to the height of the displayed information. The user then operates the oven.

Republic of Korea Patent Publication No. 2015-141797 discloses a structure that can adjust the height of the shelf of the oven. This is a structure in which the shelf height of the oven can be adjusted by applying a link structure to a height corresponding to the rotation radius of the link. The shelf height adjustment structure of this structure is more than twice the length of the link, it is impossible to adjust the height of the shelf. Therefore, the range in which the height of the shelf can be adjusted is limited. In addition, since the space for the link structure to be rotated must be provided, the volume of the cavity is reduced accordingly.

Korean Utility Model Publication No. 1997-10476 discloses a structure in which a rack and pinion structure are applied to the side of a cavity. The rack and pinion are operated through a gearbox and an external synchronous motor to move the shelf up and down. This is advantageous in that the height of the shelf can be adjusted by an electric motor, so that the shelf can be moved up and down without opening the door, but the height of the shelf cannot be adjusted without power being supplied.

Korean Patent No. 1688740 discloses a built-in oven in which a user automatically raises a tray according to a preset sequence by a control panel operation. However, such an oven structure is also provided with a motor 16 for generating power for moving the tray up and down and a pulley 15 for transmitting the power, as shown in FIG. 20, so that power is not supplied. If you do not, you can not adjust the height of the shelf.

In addition, all of the above ovens, the configuration associated with the shelf (tray) lifting device is exposed inside the cooking space. Therefore, the related technologies have a problem of contamination, such as dirt splashed from food, which is attached to the structure of a lifting device. In addition, the related technologies have a structure in which the structure associated with the shelf elevating device is not detachable, which makes it very difficult to clean the contaminated parts. In addition, there was a concern that the lifting operation would not work properly due to such contamination.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and there is no need to remove the shelf from the cavity and put it back into the cavity. It is an object to provide an oven to which this is applied.

In another aspect, the present invention, the shelf lifting structure is not exposed in the cavity cooking space of the oven, there is no fear that the operation of raising and lowering the height of the shelf installed in the cavity due to contamination of the lifting structure, there is no fear of occurrence of errors; It is an object to provide an oven to which this is applied.

It is another object of the present invention to provide a shelf elevating structure that can occupy a minimum space of the cavity and can be easily removed and mounted from the cavity, which can be conveniently cleaned and maintained, and an oven to which the same is applied.

In order to solve the above problems, the present invention defines a side surface of the cavity 32 of the oven 10 and the slide elevating assembly 40 is installed so as to extend in the vertical direction to the cavity side panel 35 facing each other. to provide.

The slide elevating assembly 40 is a device capable of elevating a shelf by a user's manual operation. The slide elevating assembly 40 is installed near the front side of the cavity side panel 35, that is, the door side for the convenience of the user's operation.

The slide elevating assembly 40 includes: a rail member 41 having an elevating rail 412 extending in a vertical direction; And a lifting body 50 which is lifted by the guide of the lifting rail 412.

When the lifting body 50 secures the length extending upward and downward along the lifting rails 412 to a predetermined length or more, it is not necessary to install both the slide lifting assembly 40 on the cavity front inner surface and the rear inner surface, Installation only on the inside front side of the cavity provides no problem in lifting operation and provides solid support for the shelf. That is, when the elevating assembly 40 is installed approximately ahead of the center of the shelf, when the heavy food is placed on the shelf, the elevating body 50 must support a considerable moment, and the elevating body 50 is mounted on the elevating rail 412. When it overlaps more than a considerable length in the vertical direction, the moment can be sufficiently supported.

The lifting rail 412 is provided with a plurality of fixing holes 414 in the vertical direction, and the

fitting members

46 and 47 are provided in the lifting body 50 to move away from the fixing holes 414. do.

When the fitting member is fitted into the fixing hole, the elevating body 50 is constrained downward relative to the elevating rail 412, thereby preventing the elevating body 50 from descending down the elevating rail 412 by its own weight. do. On the other hand, when the fitting member is separated from the fixing hole, the lifting body 50 is movable up and down by the guide of the lifting rail 412.

The lifting body 50 further includes an operation handle 44 that interlocks with the fitting member.

When the operating handle 44 is disposed at a position convenient for a user to access and operate, the operating handle 44 is operated without directly operating the fitting member, thereby raising and lowering the lifting body 50 with respect to the lifting rail 412. It becomes possible.

The lifting body 50 has a connection fixing portion 57 to which the connection bar 70 is fixed. Connection bar 70 is a configuration for connecting the lifting body disposed on both sides of the cavity. The connecting bar 70 connects them integrally so that the lifting bodies 50 disposed on both sides of the cavity maintain the same height and move vertically.

When the user moves only one of the elevating body 50 up and down in the slide elevating assembly disposed on both sides of the cavity, the shelf supported by the elevating body 50 on both sides is inclined. By connecting both elevating bodies 50 with the connection bar 70, even if the user operates only one of the operation handles 44, it is prevented that only one elevating body 50 is elevated.

In addition, the first shelf 88, which is installed to be elevated in the cavity, is supported by the lifting body 50 provided at both sides of the cavity. To this end, the lifting body 50 has a shelf coupling portion 551 supporting the first shelf.

The slide elevating assembly 40 further includes a cover member 42 which covers the rail member 41 and the elevating body 50 so as not to be exposed to the cavity 32 space. While cooking is performed in the cavity interior space, a portion of the food may float on the inner wall of the cavity panel 34. The cover member 42 prevents the food from splashing on the lifting body 50 and the rail member 41. Since the lifting body 50 is guided along the rail member 41, the lifting operation can be prevented from being caused by foreign matter. In addition, the food splashing on the cover member 42 can be easily cleaned as much as to wipe the surface of the flat cover member 42.

The cover member 42 is provided with a slide long hole 421 in the vertical direction, the connection fixing portion 57 and the shelf coupling portion 551 and the operating handle of the lifting body 50 through the slide long hole 421. 44 may be exposed to the cavity 32 space. That is, the cover member 42 may allow the components to be exposed to the cavity space in the slide elevating assembly 40 to be exposed through the slide hole 421, and the other components may be covered.

In this case, when the lifting body 50 includes a slide protrusion 521 fitted into the slide hole 421, the lifting body 50 may be guided up and down by the slide hole 421.

Here, the connection fixing part 57, the shelf coupling part 551, and the operation handle 44 are provided on the slide protrusion 521 so that a part of the lifting body 50 to be exposed is provided with a lifting body ( 50 may also contribute to the lifting guidance.

Lifting rail receiving grooves 512 surrounding the front and rear surfaces and the inner surface of the lifting rail 412 are provided at the upper end and the lower end of the lifting body 50. When the lifting rail receiving groove 512 is disposed farthest from the lifting body 50 in the vertical direction, the moment acting on the lifting body 50 by the first shelf can be more firmly supported.

Two or more rollers 59 which rotate in contact with the front or rear surface of the elevating rail 412 may be installed above or below the elevating rail receiving groove 512 in the elevating body 50. For example, the pair of rollers 59 may be installed directly under the lifting rail receiving groove provided at the upper end of the lifting body, and may be installed directly on the lifting rail receiving groove provided at the lower end of the lifting body. The pair of rollers 59 may be rotatably installed on the elevating body 50 so as to make a rolling contact with each of the front and rear surfaces of the elevating rail 412, respectively, and the pair of rollers 59 are provided at the same height. Can be installed.

Of course, the installation height of the pair of rollers 59 may be different from each other. If the lifting guide of the lifting body to the lifting rail 412 is made naturally, and can withstand the moment that can be applied to the lifting body 50 by the first shelf, the installation position or number of the rollers 59 may vary Can be.

The rail member 41 further includes a guide rail 413 extending in a vertical direction at a position spaced apart from the lifting rail 412, and the guide rail 413 is adjacent to the lifting body 50. The lifting body 50 can be guided and supported. That is, at least a portion of the elevating body 50 is accommodated between the elevating rail 412 and the guide rail 413 which are spaced apart from each other to extend up and down to be guided. Therefore, the lifting operation can be smoother, and the moment applied to the lifting body 50 in the first shelf can be more firmly supported by the lifting rail 412 and the guide rail 413.

The operation handle 44; A coupling shaft portion 443 penetrating the lifting body 50 laterally; A lever portion 442 extending forward from an inner end of the coupling shaft portion 443; And a handle part 441 provided at the front end of the lever part 442 and exposed to the cavity 32.

The coupling shaft portion 443 penetrates the lifting body 50 and is rotatably supported by the lifting body 50. The lever portion 442 extends radially forward from the coupling shaft portion 443, that is, from the rotation center of the coupling shaft portion. Therefore, even if a small force is applied to the handle portion 441, the force is enlarged by the lever portion 442 to act as a larger rotational force.

Since the handle part 441 is provided at the front end of the lever part 442, it may be more convenient for a user to access the handle part 441. The operation of raising or lowering the handle part 441 by the user causes the rotation of the coupling shaft part 443. In addition, the operation in which the user raises or lowers the handle part 441 coincides with the direction in which the user holds the first shelf by hand to lift the first shelf.

Therefore, when the user provides the handle part 441 together at the position where the user naturally holds the first shelf, the user may make the operation of holding the first shelf and the operation of raising or lowering the handle part 441 at once. That is, it is possible for a user to simultaneously grasp the handle part 441 and the first shelf in the vertical direction. Particularly, when the handle portion 441 is disposed directly under the first shelf, the handle portion is inconspicuous from the outside, so the appearance is better, and the handle portion is not contaminated by food placed on the first shelf.

In particular, when the handle part 441 positioned under the first shelf is interlocked to lift the fitting member away from the fixing hole, a force must be applied in the direction of lifting the handle part and the first shelf under the first shelf. Since the height fixing of is released, there is no fear that the first shelf will suddenly move downward by its own weight.

In addition, even if the handle portion 441 is accidentally touched, since the first shelf is not released when the force is applied upward, the force accidentally touching the handle portion prevents the first shelf from falling. That is, even if the handle portion is accidentally touched, the first shelf does not suddenly descend.

An outer end of the coupling shaft portion 443 may be connected to the fitting member. Since the inner end of the coupling shaft portion 443 connected to the fitting member is connected to the lever portion 442 and the outer end is connected to the fitting member, the coupling shaft portion 443 penetrating the lifting body 50 is axially oriented. Moving to prevent falling out of the lifting body (50).

For example, a pinion is provided at an outer end of the coupling shaft portion 443, and the fitting member may be a rack engaged with the slide member. According to this, the fitting member slides back and forth by the rotation of the handle part, and may be fitted into or removed from the fixing hole 414 of the lifting rail 412.

As another example, an arm having a shape away from the coupling shaft portion 443 in a radial direction from the coupling shaft portion 443 is provided as a fitting member, and is fitted into the fixing hole 414 at the radial end of the arm. You may lose or fall from it.

As another example, the engaging shaft portion 443 is provided with an arm in the form of a radially away from the engaging shaft portion 443, the slider is connected to the end of the arm hinged in a long-pin manner coupled shaft portion 443 Rotation can be converted to translational movement of the slider. Then, the slider may be fitted into or removed from the fixing hole depending on the rotation direction of the coupling shaft portion 443.

As such, if the fitting member is inserted into or detached from the fixing hole by the rotation of the coupling shaft portion 443, the kinematic structure may vary.

Meanwhile, according to the present invention, the fitting member is coupled with the operation handle 44 and the trigger 46 to operate in conjunction with the operation of the operation handle 44, and the interlocked with the trigger 46 and the fixing hole It may include an interlocking member 47 inserted into or separated from the fixing hole. According to such an interlocking structure, the operation direction of the operation handle 44 and the insertion release direction of the interlocking member 47 with respect to the fixing hole may be set differently.

When the operation handle 44 rotates, the trigger may also rotate. When the operation handle 44 performs a slide operation, the trigger 46 may also perform a slide operation.

The interlocking member 47 is inserted into the fixing hole 414 of the elevating rail 412 to support the elevating body 50 to maintain its position, and thus is firmly supported with respect to the elevating body 50. It is preferable to be installed as. On the other hand, it is preferable that the interlocking member 47 is naturally inserted and removed with respect to the lifting body 50. In view of these matters, the linkage member 47 may be configured as a slider that slides forward and backward.

The operation of the trigger 46 and the slider 47 is such that the first direction of the trigger 46 is interlocked with the fixed hole insertion movement of the slider 47, and the second direction of the trigger (the opposite of the first direction). Direction) motion can be linked to the movement of the fixed hole departure of the slider 47.

A tapered portion 473 having an inclined surface that is gradually lowered toward an end portion may be provided at an upper end portion of an end portion at which the interlocking member 47 is inserted into the fixing hole 414. In the state where the interlocking member 47 is inserted into the fixing hole 414, the tapered portion 473 is disposed above the fixing hole 414. Then, even when the interlocking member 47 is not removed from the fixing hole 414, when the lifting body 50 receives a force in a rising direction, the taper portion 473 of the interlocking member 47 is fixed to the fixing hole 414. In contact with the upper portion of the interlocking member 47 is moved in the direction away from the fixing hole (414). In other words, when the first shelf is to be raised, the first shelf can be raised only by lifting the first shelf without operating the operating handle 44.

The fitting member may be biased in a direction in which the fitting member is inserted into the fixing hole. The fitting member may be biased by the elastic spring 49, or may be biased by the weight of the operating handle 44 or the fitting member. In other words, if the operation handle 44 is not operated, the fitting member is maintained in the state inserted into the fixing hole it is possible to fix the height of the stable first shelf.

The present invention further provides an oven in which the slide elevating assembly is installed. The oven comprises: a body (30) comprising a cavity panel (34) defining a cavity (32) which is opened forward and a body (31) containing the cavity panel (34); A door 20 installed at the front of the main body 30 to open and close the front of the cavity 32; The slide elevating assembly 40 is installed so as to extend in the vertical direction, respectively, in the cavity side panel 35 defining both sides of the cavity; A connection bar 70 interconnecting the connection fixing parts 57 facing each other with a cavity therebetween; And a first shelf 88 supported by the shelf coupling unit 551.

The slide elevating assembly 40 may be fixed to the front of the cavity side panel 35 to be easily accessible by the user, and is fixed to the inner side of the cavity side panel in a module form, so that it is very easy to attach and detach.

A first fixing rail 82 extending in the front-rear direction is fixed to the shelf coupling part 551 of the lifting body 50 of the slide elevating assembly 40, and the first fixing rail 82 is fixed to the first fixing rail 82. The first moving rails 83 are installed to be slidably moved in the front and rear directions with respect to each other. The two first moving rails 83 provided at both sides of the cavity are fixed to the first shelf frame 80 and the first shelf The first shelf 88 may be mounted and supported on the frame 80. Then, the first shelf frame 80 can be pulled in and out in the front-rear direction by the first moving rails 83 fixed at both ends thereof.

In addition, a second fixing rail 92 is fixed to a lower portion of the inner side surface of the cavity side panel 35, and the second fixing rail 92 is slidably moved in the front-rear direction with respect to the second fixing rail 92. A second moving rail 93 is installed so that the second moving rails 3 provided on both sides of the cavity are fixed to each other by a second shelf frame 90, and a second shelf on the second shelf frame 90. 98 may be mounted and supported. Accordingly, two

shelves

88 and 98 may be installed in the cavity, and the shelf 88 disposed above may adjust the height of the shelf, and thus the utilization of the oven may be further increased.

The second groove is located farther from the lifting rail 412 than the first groove when viewed in the longitudinal direction of the slider groove. Due to the difference in depth between the second groove and the first groove, a stepped shape exists in the boundary portion between the first groove and the second groove.

The slider 47 extends from the slider body 471 to the fixing hole of the lifting rail from the slider body 471 accommodated in the second groove 5072 and is accommodated in the first groove 5051. The engaging protrusion 472 is included. The slider body 471 is received deeper in the slider groove 507 than the engaging protrusion 472. Accordingly, the stepped shape of the boundary portion between the slider body 471 and the engagement protrusion 472 interferes with the stepped portion between the first groove and the second groove. That is, the slider 47 moves outwardly to a position where the boundary portion between the slider body 471 and the engagement protrusion 472 abuts against the boundary portion between the first groove and the second groove, and thus the engagement protrusion 472. Is to be inserted into the fixing hole of the lifting rail.

The second groove 5072 includes an elastic spring 49 that elastically supports the slider 47 toward the fixing hole 414. The elastic spring may be a compression coil spring and may be located at an opposite portion of the slider body 471 in the direction in which the engaging projection 472 extends.

[Operation and Maintenance of Slide Lift Assembly]

Hereinafter, an operation of elevating the first shelf 88 using the slide elevating assembly according to the present invention and a method of maintaining the slide elevating assembly will be described.

The user may withdraw the first shelf frame 80 to the front. In this case, the first moving rail 83 slides forward relative to the first fixing rail 82. The user may put food on the drawn first shelf 88.

After the user pushes the first shelf 88 back into the cavity, the height of the first shelf 88 may be adjusted. The user may operate to lift or lower the first shelf 88 while holding the operation handle 44 together with the first shelf 88.

When the user grips the operating handle 44 and the handle portion 441 of the operating handle 44 is raised, the operating handle 44 is rotated about the coupling shaft portion 443, and thus the lifting body 50 The trigger 46 installed on the side of the second surface 502 is rotated. When the trigger rotates and the trigger lever 462 pushes the slide body 471 of the slider 47, the engagement protrusion 472 is released from the fixing hole 414. As the handle portion 441 is raised, the slider 47 retracts from the fixing hole 414 and the stopper 4711 of the slider reaches the end of the stopper hole 4834 of the third fixing part. Continue until you can't.

If the user detects that the first shelf (elevating body) is unlocked to move up and down while holding the operating handle 44 together with the first shelf, the first shelf is held in the state of holding the operating handle 44. You can move up and down.

On the other hand, as described above, the engaging projection 472 of the slider 47 is provided with a tapered portion 473. Therefore, when the user raises the shelf, the shelf can be lifted even if the operating handle 44 is not held.

On the other hand, when the user wants to lower the shelf, the user can hold the operating handle 44 to lower the shelf. When the user releases the operation handle 44 in the operation of lowering the shelf, the slider 47 is biased by the elastic spring 49 toward the lifting rail 412, so that the shelf is lowered and the height of the operation handle 44 is released. The slider 47 is immediately inserted into the fixing hole 414 immediately below so that the shelf no longer descends.

When the user closes the door 20 and starts cooking in the state where the height is adjusted in this way, the interior space of the cavity becomes hot and the cooking proceeds. After the cooking is completed, the user can easily take out the cooking by drawing the first shelf.

According to the present invention, the foreign matter is not splashed into the inside of the slide elevating assembly by the cover member 42, but a user who wants to clean it is possible to remove and maintain the slide elevating assembly from the oven.

First, as shown in FIG. 9, the first fixing rail 82 and the shelf connection part 45 are separated from each other when the first shelf frame 80 and the first moving rail 83 are drawn out. Then, the first shelf frame, the first moving rail 83 and the first fixed rail 82 can be removed. Since the shelf connection portion 45 is located in front of the cavity, the above separation operation can be made conveniently.

Then, the connecting bar 70 is separated from the lifting body 50.

The lifting body 50 itself is not interfered by the rail member 41 inwardly in the width direction of the oven, ie inwardly. The lifting body 50 can be easily separated from the rail member 41 by removing the connection bar 70 described above. Therefore, when the operating handle 44 is raised to allow the slider 47 to be pulled out of the fixing hole 414 of the rail member 41, the lifting body 50 moves together with the components installed on the second surface 502 side of the rail. It can be separated from the member 41. At this time, the user can remove the lifting body 50 and the cover member 42 together.

Finally, the rail member 41 may be separated from the inner side surface of the cavity side panel 35.

Mounting of the slide lifting assembly may proceed in the reverse order of the above.

The slide elevating assembly having such a structure that can be easily attached and detached can be additionally installed in an existing oven.

As described above, the present invention has been described with reference to the drawings, but the present invention is not limited to the embodiments and drawings disclosed herein, and various modifications may be made by those skilled in the art within the scope of the technical idea of the present invention. It is obvious that modifications can be made.
