Description

[0001]
TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to an outer configuration of an integrated heating cooker.
[0002]
[Prior art]
FIG. 12 is a diagram showing the size of a cabinet of a general kitchen.
[0003]
There is a built-in heating cooker that is built in and used in a general system kitchen. A kitchen module incorporating such a built-in heating cooker is predetermined as a standard, and has an opening with a width of 560 mm and a depth of 460 mm on the upper surface and an opening with a width of 600 mm and a height of 220 mm on the front surface. . As a method of incorporating a cooker into the opening, there are an integral type and a split type. As shown in FIG. 13, the integrated type is installed by rotating the front of the cooker from the top of the kitchen and dropping it.
[0004]
On the other hand, as shown in FIG. 14, the split type first incorporates the upper unit constituting the stove of the cooker from the top of the kitchen, and then, from the front of the kitchen, the lower unit constituting the roaster unit and the operation unit is replaced by the upper unit. Connect with and incorporate. In any case, after installation, it is suspended from the top plate of the cabinet.
[0005]
In the case of an integrated cooker, the depth of the cooker itself is larger than the depth of the opening on the upper surface of the kitchen, so the cooker front is first dropped into the opening, and then set while rotating. At this time, the rear part of the cooker is configured to escape as shown in FIG. 13 so as not to interfere with the upper surface of the kitchen.
[0006]
The method of locking the outer case and the back case is as shown in FIGS. The outer side surface is constituted by an outer case to the rear end, and the back case substantially constitutes only the rear surface of the outer case.
[0007]
[Problems to be solved by the invention]
However, such a mounting configuration of the outer case and the back case is joined by a plurality of flange surfaces facing in various directions, and many gaps are formed, such as corners, ridges, and end surfaces near the flanges. However, a leak phenomenon occurs in which water or oil that has entered the inside of the body leaks out from the gap, or hot air is sucked in from the gap near the cooling air inlet.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the cooking device of the present invention is configured such that an outer case forming both side surfaces and a bottom surface and a back case forming a rear surface and a substantially side surface are joined by a flange surface which is flush with the outer rear portion. With this configuration, the heating cooker is configured such that the gap between the mating surfaces of the outer case and the back case is reduced.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
According to the first aspect of the present invention, a plurality of heating units, a control unit that controls the heating unit, an operation unit that inputs an operation of the heating unit, and main parts of the heating unit, the control unit, and the operation unit And a top plate provided above the outer shell, wherein the outer shell is narrower than an outer case forming side and bottom surfaces of the outer shell, and a rear surface of the outer shell and a width of the outer case. Since the back case, which forms the substantially side surface, is joined at the flange surface which is substantially flush with the back of the outer shell, there is no bent portion at the mating surface of the outer case and the back case. And leakage of water or oil from inside the container can be minimized.
[0010]
According to the second aspect of the present invention, in the configuration of the first aspect, the lower end of the back case is configured to enter the inside of the lower flange surface of the outer case, so that water is formed along the inclined portion of the inner surface of the back case. Even when water flows in, the water flowing from the lower end of the back case is located inside the flange bend below the outer case, so that there is no danger of water leaking outside the body.
[0011]
According to the third aspect of the present invention, in the configuration according to the second aspect, the lower end of the back case is configured to abut against a concave portion or a convex portion provided on the outer bottom surface, so that a force is applied to the outer portion of the product from behind. Even in the case where it is added, the back case is brought into contact with a concave portion or a convex portion having a larger supporting force than the flange surface, so that the deformation of the back case can be reduced and the rigidity of the product can be maintained.
[0012]
According to the fourth aspect of the present invention, in the configuration of the first or second aspect, one or a plurality of concave portions or convex portions are provided at an end of a lower flange surface of the outer case, and a lower end of the back case is provided with the concave and convex portions. By configuring so as to engage with the system, in addition to the effect of claim 3, even when a force is applied to the product enclosure from the side, the displacement and distortion of the enclosure case and the back case can be suppressed. In addition, the gap between the flange surfaces can be reduced, and leakage of water or oil from inside the body can be suppressed as much as possible.
[0013]
According to the fifth aspect of the present invention, in the configuration according to any one of the first to fourth aspects, water penetrates from the rear side of the outer shell along the inside inclined surface of the back case by the configuration in which the outer shell bottom surface is inclined downward from the rear to the front. Even in this case, since the water can be smoothly fed forward without accumulating at the outer bottom, leakage of water or oil from the mating surface of the outer case and the back case of the flange portion can be suppressed as much as possible.
[0014]
According to the sixth aspect of the present invention, in the configuration of the first to fifth aspects, when the heating unit is of an induction heating type, an intake port for cooling the inside of the body is provided behind the top plate of the cooker. Since the exhaust port is often opened widely, and since the top plate is made of a single piece of glass, water and oil easily penetrate into the body through these openings. The effect of can be further exhibited.
[0015]
【Example】
Hereinafter, embodiments of the present invention will be described with reference to the drawings. In this embodiment, the case where the built-in heating cooker is an induction heating cooker will be described. Further, since the configuration inside the outer shell is almost the same as that of the related art, detailed description will be omitted.
[0016]
(Example 1)
FIG. 1 is a structural view of the built-in induction heating cooking of the present invention.
[0017]
A top plate (hereinafter referred to as a top plate) is provided at the upper part of the outer periphery of the cooker. An induction heating coil 3 is provided below the top plate 2 by being pressed by a spring. Similarly, as a heat source other than the induction heating coil 3, a radiant heater 4 is provided to be pressed under the top plate 2. Below the induction heating coil 3 is a control board 7 including an inverter circuit for controlling the induction heating coil 3. Further, there is a roaster 5 for baking fish and the like. And the operation part 6 which operates each heating part is provided in the outer shell front.
[0018]
FIG. 2 is an assembled state diagram of the built-in induction heating cooking of the present invention.
[0019]
Such a built-in heating cooker is used by being incorporated in a cabinet 8 of a kitchen. The size of the cabinet 8 is such that the size of the top and front openings is determined as a module common to kitchen makers (see FIG. 12), but the distance from the front of the cabinet 8 to the front edge of the top opening (FIG. 3). (A)) and the size of the corner radius of the upper opening vary depending on each kitchen maker. In general, the front of the cabinet 8 and the front of the cooker are installed together, but the distance of (A) to the length of the neck portion of the built-in heating cooker ((B) in FIG. 3) is longer. If it is shorter, lower the cooker as far as possible and adjust the installation position. At this time, if the width of the back case 9, which is the rear surface of the outer shell, is larger than the value obtained by subtracting the two corner radius dimensions from the width of the upper opening of the cabinet 8, the corner radius of the upper opening of the cabinet 8 becomes larger. Interference with the ridge of the case 9 makes it impossible to lower the cooker to the innermost position, and the front of the cooker may protrude from the front of the cabinet 8. For this reason, the width of the back case 9 on the rear side of the cooker is set to be shorter by about 10 mm than the width of the entire outer shell. With such a design, the side surface and the rear surface of the outer shell cannot be connected by one ridge. Therefore, it is considered appropriate to design the side and rear surfaces of the outer shell with separate components in terms of design.
[0020]
FIG. 4 is a configuration diagram of the outer case and the back case of the first embodiment.
[0021]
The outer case 1 is a component that forms the side and bottom surfaces of the cooker outer shell, and the back case 9 is a component that forms the rear surface of the cooker outer shell and the rear side surface that is slightly smaller than the width of the outer case 1. The following can be considered as a configuration for locking the two components. First, the rear ends of the left and right side surfaces and the bottom surface of the outer case 1 are bent inward to form the flange portion 12. At this time, the three flange portions 12 are substantially on the same plane.
[0022]
On the other hand, the back case 9 is formed with left and right side surfaces so as to be slightly smaller than the width of the outer case 1 from the surface that becomes the outer surface of the outer case 1, and further bent outward to be joined to the flange portion 12 from the side surface of the outer case 1. The flange portion 12 of the back case 9 is configured. Similarly, the lower end of the rear surface is bent to form the flange portion 12 so as to be joined to the flange portion 12 from the side surface of the outer case 1. Then, the flanges 12 of the outer case 1 and the back case 9 are combined and fixed with screws or claws. In this example, the flange surface is perpendicular to the top plate 2, but may be inclined.
[0023]
FIG. 5 is a view of the vicinity of the flange surfaces of the outer case and the back case viewed from above with the top plate removed.
[0024]
In the case of the induction heating cooker, the control board 7 and the induction heating coil 3 inside the cooker generate heat, and thus need to be cooled. Therefore, an intake port 11 and an exhaust port are generally provided behind the top plate 2. Further, a fan case 10 that forms a duct from the intake port 11 to the casing of the cooling fan is provided. The duct of the intake port 11 is formed by the inner surface of the back case 9 and the fan case. Due to the construction of the assembly, there is a joint surface, and a gap is always formed near the joint surface. However, since the joint surface of the flange can be located forward of the intake port 11, leakage of cooling air can be suppressed, and cooling can be achieved. Efficiency can be improved.
[0025]
Further, since the intake area can be increased up to the joint surface, the amount of cooling air can be increased. Further, the pressure loss can be suppressed by increasing the intake area, and the number of rotations of the fan for obtaining the same air volume can be suppressed, so that the noise of the cooking device can be reduced.
[0026]
With the above configuration, the flange surface can be configured with three flange surfaces, and the gap between the roots of the flange bent portions and the mating surfaces of the surfaces can be reduced as compared with the case where the flange surface is configured with four or more flange surfaces. The leakage of water and oil and the outflow of hot air can be reduced.
[0027]
In addition, since the gap is reduced, the possibility that cockroaches, ants, and the like enter the body is reduced, and the risk that the internal control board is short-circuited by these small animals is reduced. In addition, since one vertical ridge can be formed by being constituted by one bending flange from the top to the bottom on the outer side surface, for example, if the cooking device is accidentally dropped or another object is hit, Since the rigidity against an external force against the outer shell is increased, the outer shell is less likely to be deformed, and the gap between the joint surface between the outer case 1 and the back case 9 can be reduced.
[0028]
In addition, even an inexpensive packing material having a low cushioning property can provide sufficient cushioning against deformation of the outer shell, and can reduce the number of packings, so that transportation costs can be reduced.
[0029]
(Example 2)
Second Embodiment A second embodiment of the present invention will be described with reference to the drawings.
[0030]
FIG. 6 is a configuration diagram of the outer case and the back case according to the second embodiment of the present invention, and FIG. 7 is a cross-sectional view of the outer case and the back case of the second embodiment of the present invention.
[0031]
As in the first embodiment, the outer case 1 is configured such that the bottom surface is bent inward to form the flange portion 12, and the lower end of the back case 9 is positioned inside the bent portion of the bottom surface flange portion 12. If the lower end of the back case 9 is left uncut, deformation such as distortion is likely to occur. Therefore, even if the front end is slightly bent, distortion is unlikely to occur. Similarly, the same effect can be obtained by attaching a bead near the tip. The following configuration can be considered as the configuration of the flange surface. The bending angle of the bottom of the outer case 1 and the angle of the inclined surface below the back case 9 are the same, and the back case 9 is fixed with screws or claws so that the back case 9 is on the inside.
[0032]
It is also conceivable to make the flange surface vertical only in the vicinity of the screws and claws in consideration of the ease of work during assembly. The lower end of the back case 9 when assembled is positioned lower than the tip of the bent flange portion 12 below the outer case 1.
[0033]
Furthermore, by providing a convex portion on the bottom surface of the outer case 1 so as to contact the lower end of the back case 9, even when a force is applied to the back case 9 from behind, the back case 9 is prevented from biting inside. Can be. As for the shape of the convex portion, it is easy to attach a cut-and-raised claw to the bottom surface of the outer case 1, but it is preferable that the convex portion is formed by stepping so as not to make a hole in the outer case in consideration of water leakage.
[0034]
Also, as shown in FIG. 8, by providing the bottom of the outer case 1 with a gentle slope descending from the rear to the front, water and oil flowing along the inside of the back case 9 do not stay forward on the bottom of the outer case. Since the water flows smoothly, the possibility that water leaks out of the body from the joint surface between the outer case 1 and the back case 9 is reduced. Further, a similar effect can be obtained by providing a convex bead on the bottom surface of the outer case 1 as shown in FIG. 9 so that the tip of the lower end of the back case 9 enters the inside of the bead.
[0035]
With the above configuration, an intake port and an exhaust port are provided behind the top plate with an induction heating cooker, etc., and a user accidentally spills water or oil on the top plate, and cooks from the intake port. Even if water enters inside the container and flows along the inner surface of the back case 9, there is no danger of water leaking to the outside of the container through a gap between the outer case 1 and the back case 9. Objects stored inside or below the cabinet 8 need not be soiled.
[0036]
Further, even when an external force such as dropping or hitting an object is applied to the outer shell, deformation of the outer case 1 and the back case 9 (particularly, the flange portion 12) can be suppressed, and the gap between the joining surfaces can be kept narrow. Because of this, it is possible to prevent leakage of water and cooling air from outside the container.
[0037]
(Example 3)
Third Embodiment A third embodiment of the present invention will be described with reference to the drawings.
[0038]
FIG. 10 is a configuration diagram of an outer case and a back case according to the third embodiment of the present invention.
[0039]
Similar to the second embodiment, the outer case 1 and the back case 9 are configured so that the flange surfaces thereof are aligned with each other. The convex shape of the outer case 1 and the concave shape of the back case 9 are configured to engage with each other. Then, when they are engaged with each other, the tip of each component is set inside.
[0040]
The rear surface of the back case 9 is composed of an upper vertical surface and a lower inclined surface, and the side surface and the flange surface constituted by both sides of the vertical surface are replaced by the side surface and the flange constituted by both sides of the inclined surface. Make the mating surfaces overlap inside the surface. By overlapping in this way, it is possible to make it difficult for water that has entered from above to leak out of the vessel.
[0041]
Further, when the outer case 1 and the back case 9 are fixed with screws on the flange surface, by fastening together at the place where the flange surface of the back case 9 overlaps, a force that changes the angle between the vertical surface and the inclined surface is obtained. The resistance of the flange surface in the shear direction is large, and it is difficult to deform. At the same time, the number of fixed parts can be reduced, so that the man-hour and cost can be reduced.
[0042]
FIG. 11 is a side sectional view of an outer case and a back case according to the third embodiment of the present invention.
[0043]
If the tip of the convex portion of the outer case 1 is bent so as to be in contact with the inner surface of the back case 9 when assembled, the gap between the joining surfaces can be reduced. Also, there is no particular problem even if the outer case 1 is reversed from the concave portion and the back case 9 is reversed from the convex portion.
[0044]
It is the simplest configuration that the number of convex portions of the outer case 1 flange portion 12 is one provided at the center and fixed at that position with screws or the like. However, because the engagement is on the inside, if a force is applied to the back case 9 from the side, such as when the product is accidentally dropped, the lower end of the back case 9 is deformed from the mating surface and slips inward. And the gap becomes large. For this reason, it is desirable to provide a plurality of convex portions of the outer case 1 flange portion 12 in addition to the center to increase the engagement range.
[0045]
With the above configuration, even if the flange surfaces of the outer case 1 and the back case 9 are not pressed into contact with a plurality of screws or claws, the minimum required screws and the concave and convex portions engage with each other to prevent the load due to the external force. The gap between the mating surfaces of the outer case 1 and the back case 9 can be kept small.
[0046]
【The invention's effect】
As described above, according to the invention of the present application, it is possible to reduce the number of flange surfaces that contact the outer case and the back case that constitute the outer shell, and to reduce the gap between the flanges and the gap near the bent portion. It is possible to prevent water and oil from entering the inside of the vessel from leaking out of the vessel and also prevent leakage of cooling air near the intake port. On the other hand, even when an external force is applied to the outer shell when the product is dropped or the like, the rigidity of the contacting portion can be increased, so that the outer shell is less likely to be deformed.
