Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a heating cooker used in general households.
[0002]
[Prior art]
The prior art will be described by taking the upper unit portion of the embedded induction heating cooker as an example. Conventionally, this kind of embedded induction heating cooker has a structure as shown in FIGS. In other words, 1 is an upper unit portion that is dropped into the upper surface opening of the sink 2, and 3 is a lower unit portion that is slid from the front surface of the sink 2 and engages with the upper unit portion 1. The upper unit section 1 has a box-shaped upper unit case 4 and a top plate 5 that covers the case from above, and a heating coil, a control circuit board, and the like inside. The heating coil is located below the plate pattern 6 of FIG.
[0003]
A heater unit 9 for heating with the heating wire 8 is disposed below the plate pattern 7. A mounting plate 10 is fixed to the heater unit 9 with screws 11, and an upper unit case is inserted into an engagement hole 12 provided outside the outer periphery of the heater unit 9 via an insulating plate 13. 4 is engaged with a support shaft 14 provided on the base plate 4. At this time, the heater unit 9 is pressure-bonded to the top plate 5 by the heater spring 15 inserted into the support shaft 14.
[0004]
Further, the energizing terminal 16 of the heater unit 9 is located on the side surface of the main body case, and the heating wire 8 is connected to the heat insulating material 17 on which it is placed by the U-shaped metal fitting 18. It is fixed on the lower side (contact side with the heat insulating material 17).
[0005]
The lower unit section 3 includes a roaster section 19 for grilling fish, a kangaro-pocket type operation section 20 and the like.
[0006]
[Problems to be solved by the invention]
However, with such a structure, the mounting unit 10 is required when the heater unit 9 is mounted in the upper unit case 4, which increases the number of parts and the number of assembly steps, leading to an increase in cost and engaging. Since the hole 12 is located outside the outer periphery of the heater unit 9, a limited space in the upper unit case 4 is removed, and the circuit board and the cooling fan motor are removed. There has been a problem that restrictions on arranging other parts such as the above increase.
[0007]
Further, since the energizing terminal 16 is located on the side surface of the main body case of the heater unit 9, the same problem has been presented.
[0008]
Further, the heating wire 8 placed on the heat insulating material 17 is fixed at the lower side of the heating wire 8 with a U-shaped metal fitting 18, so that the workability at the time of driving is poor and the heating wire pitch is set. There was also the possibility of spreading.
[0009]
[Means for Solving the Problems]
In order to solve this problem, according to the present invention, a terminal block for fixing a terminal provided at the end of the heating wire of the heater unit is provided on the lower surface of the outer case.
[0010]
As a result, when the heater unit is attached to the upper unit case, the energizing terminal does not protrude from the outer periphery of the heater unit, so that the space in the upper unit case can be used effectively.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
The invention according to claim 1 is provided with a flat top plate and a heater unit that covers the lower side of the top plate, and the heater unit is a heat generator. A terminal provided at the end of the heating wire of the heater unit is mounted and fixed on the heater unit , protrudes below the outer case through the heat insulating material, and is provided on the lower surface of the outer case . It is fixed directly to the terminal block and faston connected to the extension. When the heater unit is attached to the upper unit case, the energizing terminal does not protrude from the outer periphery of the heater unit. -It has an effect that the space in the space can be used effectively.
[0012]
In addition, the terminal provided at the end of the heating wire of the heater unit protrudes below the outer case through the heat insulating material on which the heating wire is placed and fixed, and the shape is stable. Therefore, the heater unit can be easily penetrated to the outside of the heater unit via the heat insulating material when the heater unit is assembled.
[0013]
Further, provided on the heating wire end terminals, outer Ke - has been directly fixed to the terminal block provided in the scan lower surface, it has a stable effect of shape Ru are Faston connection keep the conductive terminal .
[0014]
【Example】
Example 1
An embodiment of the present invention will be described below with reference to the drawings, taking the upper unit portion of the embedded induction heating cooker as an example. In addition, since the external appearance which can be put in the Example of this invention is substantially the same as a prior art example, it abbreviate | omits.
[0015]
In FIG. 1, 21 and 22 are an upper unit case 21 and a top plate 22 that form an upper unit part that is dropped into the upper surface opening of the sink, and has a heater unit 23 inside. A heater unit 23 includes a coil heater 24 as a heating wire, a silica-based powder heat insulating material 25 for mounting and fixing the coil heater 24, an outer case 26 containing them, a terminal 27 for energizing, and a terminal block. 28. On the lower surface of the outer case 26, there are provided three recesses 32 that engage with a heater spring 30 inserted into a support shaft 29 provided in the upper unit case 21 via an insulating plate 31.
[0016]
Next, the operation of the configuration of this embodiment will be described. When the heater unit 23 is set in the upper unit case 21, it can be set on the heater spring 30 without attaching any additional parts, so that the workability can be remarkably improved and the engaging portion is provided in the outer case. Since it does not protrude beyond the outer periphery of the case 26, the space in the upper unit case 21 can be used effectively.
[0017]
Hereinafter, another embodiment of the present invention will be described with reference to FIG. In the embodiment of FIG. 2, a terminal block 43 is provided on the lower surface of the outer case 42 of the heater unit 41. A substantially straight portion 45 of the coil heater 44 penetrates the heat insulating material 46, and a terminal 47 provided at the tip of the coil heater 44 is screwed to a conductive plate 48 of the terminal block 43.
[0018]
Next, the operation of the configuration of this embodiment will be described. Since the energizing terminal portion does not protrude from the outer periphery of the outer case 42, the space in the upper unit case can be used effectively.
[0019]
(Example 2)
Hereinafter, a second embodiment of the present invention will be described with reference to FIG. In the embodiment of FIG. 3, the terminal plate 52 formed of metal welded to both ends of the coil heater 51 passes through the heat insulating material 53 and conducts the terminal block 55 provided on the lower surface of the outer case 54. Screws are fixed to the plate 56.
[0020]
Next, the operation of the configuration of this embodiment will be described. When the heater unit is assembled, the terminal plate 52 has a stable shape when penetrating the heat insulating material 53, so that it can be prevented from being caught during the penetration, and workability can be remarkably improved. It is.
[0021]
Example 3
Hereinafter, a third embodiment of the present invention will be described with reference to FIG. In the embodiment of FIG. 4, a terminal board 62 made of metal welded to both ends of a coil heater 61 penetrates the heat insulating material 63 and is made of a resin terminal block provided on the lower surface of the outer case 64. The screw is directly fixed to 65 and fastened to the extension 66.
[0022]
Next, the operation of the configuration of this embodiment will be described. Since the terminal plate 62 is directly fixed, it is excellent in stability and no conductive plate is required, so that the material cost can be rationalized.
[0023]
【The invention's effect】
As is clear from the above embodiment, according to the invention described in claim 1, when the heater unit is attached to the upper unit case, the energizing terminal does not protrude from the outer periphery of the heater unit. This means that the space in the upper unit case can be used effectively.
[0024]
Further , the shape is stable, and when the heater unit is assembled, the heat unit is easily penetrated to the outside of the heater unit.
[0025]
