Reference numeral 28 denotes an interlocking connecting shaft that connects the bases of the first rotating arms 23 facing left and right. The interlocking connecting shaft 28 is configured so that both the first rotating arms 23 rotate together.
[0020]
29 is a cooking device, for example, a microwave oven, usually stored in the cabinet 21, and includes an operation unit 30 such as a heating timer in the front, an inverter power supply 31, a solid oscillation element 32, and the like. Reference numeral 33 denotes detection means installed behind the microwave oven 29, which is configured to abut against the cabinet 21 when the microwave oven 29 is stored, and is configured to cut off the energization to the inverter power supply 31 when stored. A handle 34 for raising and lowering is provided in front of the bottom surface 35 of the microwave oven 29 and is constituted by a pipe or the like.
[0021]
A storage rack 36 is provided above the microwave oven 29. The storage rack 36 includes a main body 37, side plates 38 connected to the main body 37, pipes bent into a U-shape for controlling the storage height, and the like. 39, and the upper ends of the main body 37 and the side plate 38 serve as the uppermost portion 40 of the storage rack 36.
[0022]
The storage rack 36 is installed in the upper space 41 of the elevating support unit 25 during storage, and the width dimension of the storage rack 36 is wider than the microwave oven 29 by bending the first and second rotary arms 23 and 24. Is done.
[0023]
The distal ends of the first and second rotary arms 23 and 24 pivotally supported by the elevating support unit 25 are pivotally supported by the support member 42 and connect the side plate 38 forming the wide storage rack 36 to the support member 42. By doing so, a four-sided parallel link mechanism 43 is configured, and the microwave oven 29 and the storage rack 36 are supported to be movable up and down.
[0024]
In addition, the first and second rotating arms 23 and 24 are provided with an inclination correcting means 44 for preventing the microwave oven 29 and the storage rack 36 from being inclined. As the inclination correcting means 44, the distance R1 between the pivot points of the first rotating arm 23 is configured to be several mm longer than the distance R2 between the pivot points of the second rotating arm 24.
[0025]
By slightly deforming the parallel link mechanism 43 in this way, there is a gap at the pivot point of the first and second rotating arms 23 and 24, and thus the microwave oven 29 and the storage rack generated by the weight of the microwave oven 29 and the stored items. The inclination of 36 to the front is prevented.
[0026]
In addition, the raising / lowering support unit 25 includes both or either one of the buffering means 45 and the urging means 46 that act in conjunction with the rotation of the second rotating arm 24, that is, the raising / lowering of the microwave oven 29 ( (Only described in FIG. 1). Reference numeral 47 denotes an openable / closable door provided in front of the cabinet 21, and 48 denotes a hinge for opening and closing (described only in FIG. 3).
[0027]
In the above configuration, when the microwave oven 29 and the storage rack 36 are lowered, the user holds the handle 34 and pulls it down, and the microwave oven 29 and the storage rack 36 are pivotally supported so that the lifting support unit 25 can rotate. The parallel link mechanism 43 and the inclination correcting means 44 formed by the first and second rotating arms 23 and 24 always rotate in an arc shape as indicated by a one-dot chain line in FIG. 1 in the horizontal state and are lowered to the maximum lowering position. . At this time, the buffer means 45 and the urging means 46 act so that the microwave oven 29 and the storage rack 36 descend slowly.
[0028]
Here, in the microwave oven 29 and the storage rack 36, the first and second rotary arms 23 and 24 that support the microwave oven 29 and the storage rack 36 are bent in a substantially S shape and a substantially L shape instead of a linear shape. Since the rotary arms 23 and 24 are connected to the storage rack 36 and the distance between the pivot points (R1 and R2) is large, the rotary arms 23 and 24 can be lowered greatly. That is, since the first and second rotary arms 23 and 24 that support the storage rack 36 are bent, the position at which the first rotary arm 23 contacts the bottom plate 22 of the cabinet 21 is considerably lower than the linear arm. Thus, the uppermost portion 40 of the storage rack 36 can be lowered to a position lower than the position of the bottom plate 22 of the cabinet 21.
[0029]
In this embodiment, the storage rack 36 is configured by the stopper 26 so that the uppermost portion 40 stops at a height substantially equal to the height of the bottom plate 22 of the cabinet 21.
[0030]
Then, after the user performs cooking work at the maximum lowered position or puts in and out the stored items, when the microwave oven 29 and the storage rack 38 are raised and stored, if the user holds the handle 34 and pushes it up again, the microwave oven 29 and the storage device are stored. The rack 36 rotates in an arc shape as in the lowering, and is stopped and stored at a predetermined position in the cabinet 21 by a stopper 26. At this time, the urging means 46 acts so that the operating force when raising the storage rack 36 is reduced.
[0031]
Next, the installation example of the raising / lowering type cooking appliance of this invention is demonstrated.
[0032]
As shown in FIG. 3, the cabinet 21 was assumed to be a standard wall cabinet, and adopted a height of 700 mm and a depth of 350 mm as external dimensions. The standard installation height of the cabinet 21 is generally around 2300 mm from the floor surface 50 to the top surface 51 of the cabinet 21 due to the distance relationship with the floor cabinet 49 installed below the elevating cooking appliance. The total height (A) of the microwave oven 29, the storage rack 36 and the horizontal connecting member 39 stored in the cabinet 21 is about 600 mm.
[0033]
When the height of the uppermost portion 40 of the storage rack 36 and the bottom plate 22 of the cabinet 21 are configured to be substantially equal at the maximum lowered position of the storage rack 36, the distance from the bottom plate 22 of the cabinet 21 to the bottom surface 35 of the microwave oven 29. (B) is around 450 mm.
[0034]
Therefore, the distance (C) from the floor surface 50 to the bottom surface 35 of the microwave oven 29 at the maximum lowered position of the storage rack 36 is about 1150 mm. Similarly, the distance (D) from the floor surface 50 to the horizontal connecting member 39 is about 1750 mm. In this embodiment, the height of the boundary surface between the microwave oven 29 and the storage rack 36, that is, the height of the storage surface for the stored items is about 1400 mm from the floor surface 50, which is about 90% of that of an adult woman (excluding the elderly). It is comprised so that it may become equivalent height.
[0035]
The height that can be taken in and out is approximately the height of the thumb with both arms raised, and can be the height to the finger joint. For adult women (excluding the elderly), the 10th percentile value obtained by subtracting the length of the fingertip (third finger length) from the height of the fingertip (upper finger tip height) is 1800 mm. In the example of equipment installation, about 90% of adult women can reach the uppermost 40 of the storage rack 36 and reach the horizontal connecting member 39, and can take in and out the stored items, and the total storage capacity of the storage rack 36 is effective. It can be used for. Further, the distance to the handle 34 in the state stored in the cabinet 21 is about 1650 mm from the floor surface 50 in this embodiment, and it is understood that it is not necessary to extend the arm extremely long.
[0036]
The floor cabinet 49 is assumed to be a standard cabinet, and the height of the counter top surface 52 is 850 mm and the depth is 650 mm from the floor surface 50. Therefore, at the maximum descending position of the microwave oven 29, a space of about 300 mm can be secured from the counter top surface 52 to the bottom surface 35 of the microwave oven 29. That is, the kitchen utensils 53 usually placed on the counter top surface 52 are about 280 mm or less for an electric rice cooker, 200 mm or less for a general pan, and 300 mm or less for a beer bottle, except for a fixed type device such as a dishwasher. The product is 300 mm or less. Therefore, it can be seen that if there is a space of about 300 mm at the maximum descending position, it will not collide with these kitchen utensils 53.
[0037]
As described above, the microwave oven 29 and the storage rack 36 are supported by the rotary arms 23 and 24 that can be moved up and down, and the lift support unit 25 that rotatably supports the rotary arms 23 and 24. The storage rack 36 can be easily moved up and down by one rotation by the rotation of the rotary arms 23 and 24, and the storage rack 36 includes accessories (turntable, square plate, etc.), an instruction manual, Many kitchen-related items can be stored, cooking workability can be improved, and an easy-to-use elevating cooking device can be provided with an inexpensive configuration.
[0038]
In addition, since the storage rack 36 is configured wider than the microwave oven 29, the storage capacity of the storage rack 36 can be increased, and an elevating cooking appliance with high storage efficiency can be provided.
[0039]
In addition, since the storage rack 36 is provided in the upper space 41 of the lifting support unit 25, it is possible to avoid contact with the lifting support unit 25 when the storage rack 36 is rotated up and down, and to maximize the width dimension of the storage rack 36. The space in the cabinet 21 can be effectively utilized.
[0040]
In addition, by providing the handle 34 protruding in front of the bottom surface 35 of the microwave oven 29, when the microwave oven 29 and the storage rack 36 are moved up and down from the cabinet 21, the handle 34 is most easily reachable and the lifting operation is facilitated. It can be carried out.
[0041]
Further, since the tips of the rotary arms 23 and 24 are connected to the storage rack 36, the distance between the pivot points of the rotary arms 23 and 24 can be increased, and stable ascending and descending can be obtained. Thus, contact between the bottom surface 35 of the microwave oven 29 and the bottom plate 22 of the cabinet 21 can be prevented.
[0042]
Further, since the rotation arms 23 and 24 are provided with the inclination correcting means 44 for preventing the inclination of the microwave oven 29 and the storage rack 36, the microwave oven 29 and the storage rack 36 are inclined due to the weight of the microwave oven 29 and the stored items. By correcting this, it is possible to prevent the stored item from moving or falling, and also to give the user a sense of security in terms of appearance.
