Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to furniture with a lifting device, such as a cooker unit having two cookers.

Conventionally used cooking units generally have a range stand with a gas or electric stove mounted on the bottom of the unit body, and a ventilation hood attached above the stove. Heat, smoke, etc. generated when the stove is used is efficiently sucked into the ventilation hood and exhausted to the outside.

However, with the recent diversification of food preferences,
Induction heating devices, gas ovens, microwave ovens, oven microwave ovens, steam oven microwave ovens, and the like, which are capable of a wide cooking range, are increasingly being used. Although these ranges are cooking devices used together with the stove, they are not structured to be housed in the cooking unit, and are therefore placed in a completely different location. Therefore, they are not easy to use. In addition, the ventilation hood mentioned above can be equipped with a large one with a height close to the ceiling and has good ventilation efficiency, but on the other hand, it is not possible to arrange other kitchen furniture, etc., and it is not possible to use the space effectively. I'm in a state where I can't say anything.

The present invention was developed in view of the above circumstances, and its purpose is to connect a rack-pinion electric drive mechanism and two spring-type weight balancers that perform a separate balancing action within the furniture body. The object of the present invention is to provide furniture with a lifting device that can accommodate a plurality of objects, such as cooking utensils, and can improve workability and effectively utilize space.

An embodiment of the present invention will be applied to a cooking device unit and will be described below based on the drawings. In the figure, reference numeral 1 denotes a cooking unit that is arranged so that one side thereof is in close contact with a wall 2 of a kitchen room. In addition, a sink 3 is provided on the lower part and a hanging cabinet 4 is provided on the upper part of the side surface. The cooking device unit 1 consists of a unit main body 5 which is a furniture main body, an electric stove 6 which is a lower cooking device, and an oven microwave oven 7 and a ventilation hood 8 which are upper cooking devices, respectively, which constitute storage objects. The unit main body 5 is formed in an inverted L-shape in cross section, and its lower side is wider in width and narrower in depth than its upper side. The electric stove 6 is placed on a cooktop 9, and its width is approximately the same as that of the unit main body 5, and its front end surface is set so that its depth is approximately equal to the upper front end surface of the unit main body 1. Set. Above oven microwave oven 7
is placed on the lifting platform 10 and is movable in the vertical direction. This lifting platform 10 is connected to a rack and pinion type electric drive mechanism 11 called a linear head, and is suspended by a spring type weight balancer 12 called a balancer.
It is slidably fitted along a guide rail (not shown). These rack and pinion electric drive mechanisms 1
1. A lifting mechanism 13 is composed of a spring type weight balancer 12 and a guide rail, and these are housed within the unit main body 5. From FIG. 4 and FIG. 5, the above rack and pinion electric drive mechanism 1
1, an electric motor 11a connected to a pinion gear is attached to a substantially central portion in the width direction of the back plate 5a of the unit main body 5, and a rack 11b that meshes with the pinion gear extends in the vertical direction. The lower end of the lifting platform 10 protrudes toward the rear side, and the lower end of the rack 11b is fitted into the substantially central portion in the width direction. The electric motor 11a is electrically connected to a toggle switch (not shown),
When it is tilted upward, the rack 11b rotates in the normal direction, and the rack 11b rises; when it is tilted downward, the rack 11b rotates in the reverse direction and descends. In addition, the above-mentioned spring type weight balancer 12
are provided at equal intervals on both the left and right sides of the rack and pinion electric drive mechanism 11. Each conical wheel 12 houses a mainspring in its case 12a and has a rope 12b wrapped around its rotating shaft.
It is formed by connecting c. The rope 12b is connected to the conical wheel 1
It hangs down from 2c and its ends are connected to both sides of the lifting platform 10. As the lifting platform 10 moves up and down, the mainspring inside the case 12a is wound up and unwound, changing the output. At this time, the diameter of the conical wheel 12c from which the rope 12b is drawn also changes accordingly, and the mainspring's It has become possible to cancel out changes and obtain a constant moment. Since two such spring-type weight balancers 12, 12 are arranged on the left and right sides of the above-mentioned rack-pinion type electric drive mechanism 11, they act independently, and no matter where the lifting platform 10 is located,
Also, even if you are biased to either the left or right side, you can balance your posture so that it is horizontal.

On the other hand, a door plate 14 is rotatably supported on the upper front side of the unit main body 5 with its upper end as a fulcrum, and the oven/microwave oven 7 is raised to a position opposite to this door plate 14. There is. When it is at the lowest position, it is regulated at a position that is at a predetermined distance from the electric stove 6 and protrudes from the door plate 14. A safety switch (not shown) is attached to the door plate 14, and is configured to cut off power from the oven/microwave oven 7 unless the oven/microwave oven 7 is in an opposing position and the door plate 14 is not opened. The ventilation hood 8 is provided with a lower ventilation port 15 that is open at its lower end surface, and is also provided with a side ventilation port 16 consisting of a large number of elongated holes on the side surface on the oven/microwave oven 7 side. Also ventilation hood 8
A mounting hole 17 is opened in a part of the wall 2 facing the
A ventilation fan 18 is attached here.

When using the electric stove 6, a toggle switch (not shown) is turned upward to energize the rack and pinion electric drive mechanism 11, and the lifting platform 10 is turned on.
to rise. At this time, the rack and pinion type electric drive mechanism 11 is placed in the center, and the spring type weight balancers 12, 12 are placed at equal intervals on both the left and right sides.
As the rack and pinion type electric drive mechanism 11 is driven, the spring type weight balancers 12, 12 on both the left and right sides keep the lifting platform 10 in the correct horizontal position without causing it to become unbalanced from side to side. This means that the increase will be maintained.

Even if a strong force biased toward either the right or left side of the lifting platform 10 is applied for some reason, the spring-type weight balancers 12, 12 exert an adjusting force to balance the lifting platform 10 in a horizontal position.

When the microwave oven 7 rises to a position facing the door plate 14, the lifting platform 10 stops,
The electric stove 6 becomes energized. When the microwave oven 7 is at the bottom, the electric stove 6 is wired to be in a non-energized state. Heat and smoke generated when the electric stove 6 is used are sucked in through the lower ventilation opening 15 and the side ventilation opening 16 of the ventilation hood 8 and are exhausted to the outside. When using the microwave oven 7, be sure to open the door plate 14 when it is located at the top. Alternatively, flip the toggle switch downwards and lift platform 1.
This is done after moving 0 downward and making it protrude from the door plate 14. The heat and smoke extracted from this will be removed from the side ventilation port 1.
6 and discharged to the outside. This lifting platform 1
Similarly, when the 0 moves downward, the rack-pinion electric drive mechanism 11 is placed in the center, and two spring-type weight balancers 12, 12 are placed at equal intervals on both the left and right sides of the rack-pinion electric drive mechanism 11. As the drive mechanism 11 is driven, the spring type weight balancers 12, 12 on both the left and right sides move up and down the lifting platform 1.
To maintain a correct horizontal posture and maintain a smooth descent without causing imbalance to the left and right. At this time, even if a strong force biased to either side of the lifting platform 10 is applied for some reason, the spring type weight balancers 12, 12 exert an adjusting force to balance the lifting platform 10 in a horizontal position.

In the above embodiment, the lifting platform 10 is connected to the lower end of the rack 11b, but the invention is not limited to this, and the arrangement shown in FIG. 6 may be used. That is, the lower end of the lifting platform 10a projects horizontally toward the rear surface, and the upper end of the rack 11b is connected thereto. The rack and pinion electric drive mechanism 11 is located below the lifting platform 10 and is in a state of lifting it up. In this case, the drive mechanism 11
can be easily attached to the main body 1. and again,
The rack and pinion type electric drive mechanism 11 is placed in the center, and two spring type weight balancers 12, 12 are arranged at equal intervals on both the left and right sides of the rack and pinion type electric drive mechanism 11. Spring type weight balancer on both sides 1
2 and 12, it goes without saying that the lifting platform 10 is always maintained in a correct horizontal position without being unbalanced to the left or right, and also maintains smooth lifting and lowering.
(The same parts as in the above embodiment are given the same numbers and the explanation is omitted.) In the above embodiment, an electric stove was used as the lower cooking device 6, and an oven microwave oven was used as the upper cooking device 7, but this is not limited to this. For example, a combination of a microwave oven and another cooking device such as an induction heating device may be used.

Further, although the present device has been described as a cooking unit, it is not limited to this, and the scope of application can be expanded to other furniture such as multi-tiered cupboards.

As explained above, according to the present invention, an object to be stored is housed in the furniture main body, and a rack and pinion type electric drive mechanism that automatically drives the object up and down is connected to the object to be stored, and the object to be stored is Since we have connected a spring-type weight balancer that constantly balances the position, it is possible to store, for example, multiple different types of cookers and use them properly, which improves usability and allows for less tiring work. At the same time, space can be used effectively. Also,
The rack and pinion type electric drive mechanism is connected to the approximate center of the storage object, and two spring type weight balancers are connected at equal intervals on both sides, each acting independently. As the storage device moves up and down, the spring-type weight balancers on both the left and right sides act independently to maintain the correct horizontal posture of the storage object without making it unbalanced from side to side. Even if a biased force is applied to either the left or right side of the stored object for some reason, the spring-type weight balancer balances the stored object by applying separate adjustment forces to return the stored object to a horizontal position. Therefore, effects such as ensuring that the stored object is always smoothly raised and lowered are achieved.
