Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cooking device such as a microwave oven.

[0002]

[Prior art]

 Conventionally, when high-frequency cookers are used by stacking them in multiple stages, simply stacking the cookers on top and bottom may cause the cookers to become very unstable when the doors are opened and closed, and may cause falls, etc. It is common practice to fix the cookers in the above with connecting fittings. For example, in Kaikaihei 3-87110, a connecting fitting is provided on the entire bottom of the rear plate to connect to the lower cooker, and the upper and lower cookers are integrated by this connecting fitting, and undesirably drop during use. It is restrained from doing.

[0003]

[Problems to be solved by the device]

 However, while the above configuration can prevent a fall accident due to the movement of the entire upper cooker when the door is opened and closed, in the configuration in which the reinforcing metal fitting is provided only at the rear part of the cooker, the connecting metal It was not possible to prevent the front part of the cooking device centering around the connecting metal fittings from moving to the left or right due to twisting, and the upper and lower cooking devices were misaligned to the left or right, which could impair aesthetics. Also, in a cooker with legs on the bottom plate, the frame top surface of the lower cooker is heavily loaded at the contact points with the legs of the upper cooker, so the frame top surface of the lower cooker is Occasionally, dents and deformations occurred.

Therefore, an object of the present invention is to provide a practical high-frequency heating cooker that solves the above problems.

[0005]

[Means for Solving the Problems]

 According to the configuration of the present invention, the cooker and the cookers stacked on top of each other are connected to each other, and the legs of the upper cooker are placed on the lower cooker from the front to the rear. It consists of a pair of reinforcing brackets with a substantially U-shaped cross section, and a connecting bracket that covers the gap between the rear walls between the upper and lower cookers and is fixed to both rear walls. Insert the reinforcing bracket into the connecting brackets. A pair of support holes are provided, and an engaging piece that is inserted into the support hole and that engages with and supports the hole edge of the support hole is erected at the rear end of the reinforcing metal fitting. The fixing metal fittings that press the upper parts of both side walls of the above from the outside are fixed to the bottom parts of both side walls of the upper cooking device.

[0006]

[Action]

 According to the present invention, since the reinforcing metal fitting is provided between the lower leg of the upper cooker and the top surface of the frame of the lower cooker, the weight of the upper cooker is dispersed and the weight is concentrated on a part. Disappears. In addition, since the fixing metal fittings provided on the lower side of the upper cooker sandwich the lower cooker from the left and right and integrally fix it, one of the upper and lower cookers receives an external force that moves laterally. Even in the case, this fixing metal works to prevent movement.

[0007]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. In the figure, 1 is an upper cooker body, 2 is a lower cooker body, and the cooker bodies 1 and 2 are high-frequency heating cookers of the same size. The cooker main bodies 1 and 2 are of a well-known lateral opening type, and food items to be heated are stored in an internal heating chamber. In addition, an operation unit for setting cooking conditions and the like is provided on the right side of the front surface, and a high-frequency generator, a cooling device, a high-voltage power supply unit, etc. are arranged inside the main body. 3 is a rubber leg provided at equal intervals on the four sides of the bottom plate of the cooker body 1 and 2, and has a columnar shape that becomes thinner toward the bottom. The cooker body 1 and 2 are supported by these legs. Has been. A pair of reinforcing metal fittings 4 are installed between the front and rear legs of the upper cooker 1 and the top surface of the frame 5 of the lower cooker 2 in a rail shape. As shown in FIG. 3, the reinforcing metal member 4 has a rod-like shape having a substantially U-shaped cross section and is long in the front-rear direction, and an engaging piece 6 having an inverted L-shape is integrally bent at the rear end. A gap 7 is formed in the front portion of the piece 6. Reference numeral 8 is a connecting member provided over the entire lower portion of the rear plate, and is fixed by being screwed together by a screw 11 that fastens the rear plate 9 and the bottom plate 10 of the upper cooker 1. A support hole 12 is provided in the connecting fitting 8 at a position corresponding to the engaging piece 6 of the reinforcing fitting 4 when installed. Numeral 13 is fixing metal fittings provided on both sides of the upper cooker 1 frame 5 and is fixed by screws 14 for fastening the frame 5 and the bottom plate 10. The lower end portion of the lower cooker body 2 is fixed at the time of mounting. It is fixed so that both side surfaces of the frame 5 are sandwiched from the outside.

When the cookers 1 and 2 are installed in a stacked manner, the reinforcing metal fitting 4 is rail-shaped on the top surface of the frame 5 of the lower cooker 2 according to the leg width of the upper cooker 1. At this time, the engaging piece 6 of the reinforcing metal fitting 4 is positioned rearward. Next, the leg 3 of the upper cooker 1 is set on the lower cooker 2 and stacked in line with the groove of the reinforcing metal fitting 4, and the support hole 12 of the connecting metal fitting 8 is inserted into the engaging piece 6 and then downward. Slide it into the gap 7 and align the screw hole 15 of the connecting fitting 8 with the screw hole 16 of the upper cooker 1 and the screw hole 17 of the lower cooker 2 respectively, and connect the connecting fitting 8 with the screw 11. Secure by tightening together. At this time, as shown in FIGS. 4 and 5, the reinforcing metal fitting 4 is supported by fitting the connecting metal fitting 8 into the gap 7 in the front portion of the engaging piece 6, so that the reinforcing metal fitting 4 is supported in the front-rear and left-right directions. Works to regulate movement to. Next, the fixing fittings 13 are screwed to the lower side walls of the upper cooker 1 with the screws 14 that fix the frame 5 and the bottom plate 10.

With the above structure, the fixing metal fittings 13 attached to the upper cooking device 1 fix the lower adjusting device 2 integrally so that both side surfaces of the frame 5 are sandwiched from the outside. As a result, when the door is opened and closed when the cooker is used, the upper cooker 1 receives an external force in the left-right direction, and the rear cooker 9 tries to move left and right with the lower cooker 2 as a fulcrum. However, at this time, the fixture 13 fixed to the upper cooker 1 contacts both sides of the frame 5 of the lower cooker 2 to suppress this movement, and the upper cooker 1 moves to the left and right. Prevent slippage.

Further, the reinforcing metal fitting 4 provided at the lower portion of the leg 3 disperses the weight of the upper cooker 1 and does not concentrate the weight on one part, and therefore the depression of the top surface of the lower cooker 2 frame 5 is formed. And deformation is suppressed.

[0011]

[Effect of device]

 According to the configuration of the present invention, it is possible to prevent the left and right shifts of the upper and lower cookers, and the deformation and dent of the top surface of the lower cooker frame, which keeps the aesthetic appearance and improves the quality of a practical high frequency wave. A heating cooker can be provided.
