Description

Description: TECHNICAL FIELD The present invention relates to a top plate unit of a heating cooker.

2. Description of the Related Art Conventionally, this type of cooking device has a structure as shown in FIGS. 9, 10, and 11. FIG.

That is, the top plate unit 1 combines the top plate 2, the top plate frames 4, 5, 6, 7 around the operation unit unit 3 and the top plate frame 8 between the top plate 2 and the operation unit unit 3. It consists of For this reason, there is no clearance a between the joints 9 to 14 of the top plate frames 4, 5, 6, 7, and 8.
May occur. Further, a sealing member A15 is wound around the outer peripheral portions of the upper surface and the side surface of the top plate 2 and the operation unit unit 3 as shown in Fig. 10, and further fitted into substantially U-shaped portions of the top plate frames 4 to 7, It is pressed upward by a top plate receiver 17 having a sealing member B16 attached to the upper surface from the back side, and the top plate frame 4 to
7 and the top plate receiver 17 are fixed by screws or the like. Further, as shown in FIG. 11, the cross-sectional shape of the top plate frame 8 at the joint between the top plate 2 and the operation unit 3 is substantially T.
Except for the letter shape, it has the same structure as the many top plate frames 4-7. Here, the purpose of the seal member A15 is to seal between the top plates 4 to 8 and the top plate 2 or the operation unit 3, and the purpose of the seal member B16 is to set the top plate 2 or the operation unit unit 3 and the top plate support. There is a buffer that prevents direct contact with 17 to prevent cracking.

However, in such a structure, even if the seal between the top plate 2 and the operation unit 3 and the top plate frames 4 to 8 is perfect, the top plate frames 4 to 8 A gap a is formed in the joints 9 to 14 from the structural point, so that spills and the like penetrate into the top plate frames 4 to 8 from the gap a, and further, the top plate 2, the operation unit 3, and the top plate frame 4 Since the top plate unit 1 integrated with the top plate support 17 and the like is fitted into the upper opening of the main body lower case 18, boil-over that has penetrated into the inside of the top plate frames 4 to 8 is prevented. There is a problem that the liquid leaks into the inside of the lower case 18 through a small gap between the upper case 8 and the top plate receiver 17. The process in which the leakage reaches the lower case 18 will be described in more detail as follows.
The dimensions of the top plate frames 4 to 8 are the top plate 2 and the operation unit 3
In order to absorb the dimensional tolerance and the backlash in assembling, the size is set to be larger than the top plate 2 or the like. For this reason,
A seal member A15 is mounted between the top plate frames 4 to 8 and the side surfaces of the top plate 2 and the operation section unit 3. However, the tightening of the seal member A is insufficient for the above-described reason. Clearance b may occur. When boiling occurs on the upper surface of the top plate unit 1 and penetrates into the top plate 2 and the upper surface end corners of the operation unit 2 through the gaps a of the joining portions of the top plate frames 4 to 8, the top frame 4 to 8 8 and the seal member A, there is a gap b between the top plate frames 4 to 8 and the seal member A in the lateral direction due to the capillary phenomenon of the boiling-over liquid, as shown by the dashed arrow in FIG. The spilled liquid spreads over the entire length of the top plate frame in contact with the gap a. Then, when the amount of the spilled liquid further increases, it reaches the space between the top plate frames 4 to 8 and the top plate receiver 17 along the inner surfaces of the top plate frames 4 to 8. Since the top plate frames 4 to 8 and the top plate receiver 17 are fixed in a point shape by screws or the like, there is a small gap other than this fixed portion, and the boiling liquid is removed from the top plate frames 4 to 8 and the top plate frame 17. It spreads in the gap between the plate supports 17, and when the amount increases further, it rises through the top plate support 17 and leaks into the lower case. Another route through which the spilled liquid leaks into the lower case 18 is when there is no gap b between the top plate frames 4 to 8 and the sealing member A15. In this case, the boiled-spilled liquid that has penetrated from the gap a between the top plate frames 4 to 8 travels along the end faces of the top plate frames 4 to 8 and reaches the inner surfaces of the top plate frames 4 to 8, and furthermore, the top plate frames 4 to 8 And the space between the top plate 17 and the gap between the top frame 4 to the top plate 17 and the top plate 17 is spread in the longitudinal direction of the top plate 17 by capillary action, and the amount of spilled liquid further increases. And leaks into the lower case 18 due to its weight.

As described above, since the boiling spill liquid that has entered from the joint space a of the top plate frames 4 to 8 spreads over the entire top plate unit 1,
It is not known which part of the lower case 18 leaks. On the other hand, the components of the cooking device main body arranged inside the lower case 18 are rarely fixedly adhered to the inner corners of the lower case 18, but since the components are easily arranged in other parts, Leakage of the spilled liquid occurred, and if dropped on the component parts, the service life of these parts was shortened and insulation failure was caused, resulting in a malfunction of the cooking device body.

Therefore, the present invention, even if a gap occurs in the top frame joint,
This prevents the liquid that has spilled over the inner surface of the lower case from leaking, or even if a leak occurs, it does not spread to the entire top plate unit and suppresses leakage only near the joint of the top plate frame. In order to prevent the dripping from leaking to the components of the cooking device main body arranged in the above.

Means for Solving the Problems And in order to achieve the above object, the present invention provides a top plate, a top plate frame that covers the periphery of the top plate and has at least one cut, and a back side of the top plate. A top plate receiver arranged and fixed to the top plate frame, a first seal member provided between the top plate, the top frame, and the top plate and the top plate receiver, A top plate unit in which a second seal member is arranged between the side surface of the top plate and the top plate frame is fitted and fixed to the upper opening of the main body lower case in the vicinity of the cut of the frame. .

Further, the top plate unit is configured to cover only the upper surface and side surfaces of the top plate in the vicinity of the cut of the top frame.

Further, the top plate unit includes a second sealing member between the top plate frame and the top plate receiver near a cut of the top plate frame.

Further, the top plate unit may further include a first member in which the top plate frame covers an upper surface and side surfaces of the top plate, and a first member which is joined to the inner surface of the first member in a point-like manner at the top plate side surface portion. And the second member is shorter than the first member and does not reach both ends of the first member.

Effect The cooking device of the present invention has the above-described configuration, and even if the liquid spilling from the cut of the top frame joint penetrates into the inside of the top frame, the side of the top plate near the cut of the top frame of the top plate unit. Since the second sealing material is arranged between the top plate frame and the top plate frame, the permeation of the spilled liquid is stopped by the second seal, and the spilled liquid does not spread to the entire top plate unit. The leakage of the spilled liquid into the case is suppressed only in the vicinity of the cut of the top plate frame.

In addition, since the top plate frame is configured to cover only the upper surface and side surfaces of the top plate in the vicinity of the top plate frame cut of the top plate unit, the boiling liquid that has penetrated from the top plate cut is located between the top plate and the top plate frame. , The boiled liquid escapes to the outside of the lower case and does not leak into the lower case.

In addition, since a second seal member is arranged between the top plate frame and the top plate receiver near the top plate frame cut of the top plate unit,
The spilled liquid that has penetrated from the cuts in the top plate frame and has traveled along the top plate frame and has reached between the top plate frame and the top plate holder is stopped by the second seal member. The transmission of the spilling liquid through the minute gap is suppressed, and the spilling liquid leaking into the lower case of the main body is suppressed only to the vicinity of the cut of the top plate frame.

Further, a top plate frame constituting the top plate unit is formed by a first member that covers an upper surface and side surfaces of the top plate, and a second member that is joined to the inner surface of the first member in a point-like manner at the side surface of the top plate. And the second member of the top plate frame is shorter than the first member, and does not reach both ends of the first member. The boiled spilled liquid is transmitted between the top plate and the first member of the top plate frame, and tends to spread over the entire top plate frame. However, the top plate frame is shorter than the first member and the first member. And the second member joined to the inner surface of the second member in a point-like manner, so that the spilled liquid is absorbed by the minute gap between the first and second members by capillary action.
When the amount of the boiling liquid increases, it leaks to the outside of the main body from between the first member and the second member, so that the leakage of the boiling liquid into the case below the main body can be suppressed.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

1 and 2, the top plate unit 21 includes a top plate 22.
And top plate frames 24-27 covering the outer periphery of the operation unit 23, and the top plate
A top plate frame 28 between the operation unit 22 and the operation unit 23 is combined. For this reason, the joints 29-34 of the top plate frames 24-28
May have a small gap c. In addition, top plate 22
As shown in FIG. 2 (FIG. 2 is a cross-section d... D 'near the top frame joint in FIG. 1), a sealing member C35
Is wound around the top plate frame 24, and is pressed upward by a top plate holder 37 having a sealing member D36 adhered to the upper surface from the rear surface side. 37 is fixed by screws. In addition, the top frame joint
A second seal member E39 is disposed only between the side surfaces 29 to 34 and between the side surface of the top plate 22 and the top plate frame 24 so as to fill a gap caused by dimensional tolerances between these components. Then, the top plate unit 23 having the above configuration is fitted and fixed in the upper opening of the main body lower case 40.

 Next, the operation of the configuration of the embodiment will be described.

Small gaps b are formed at the joints 29 to 34 of the top plate frames 24 to 28. For this reason, boil-off during cooking with a pot or the like placed on the top plate unit 21 or a cleaning solution for cleaning when the upper surface of the top plate unit 21 becomes dirty penetrates from the gap b, and the top plate frame 24 Of the top plate frame 24 and the sealing member C35 wound around the outer periphery of the top plate 22 to spread in the lateral direction. However, near the joints 29-34,
Since the second seal member E39 is arranged in this gap,
Infiltration such as boiling spill liquid is stopped here, and top plate frame 24-28
Does not spread throughout. As a result, even if the spilled liquid leaks into the lower case body 40, the leaked portion is limited only to the vicinity of the joints 29 to 34 of the top plate frames 24 to 28, so that the arrangement restriction of the main body internal parts is reduced, Unless the internal components are arranged only in the vicinity of the joints 29 to 34, the life is not shortened and the insulation is not deteriorated due to the leakage of the boiling water.

 Next, another embodiment of the present invention will be described.

In this embodiment, the structure of the top plate unit 21 is as shown in FIG. 3 in the vicinity of the joining portion 29 of the top frame (d ... d 'in FIG. 1). That is, the top plate frame 24 has only a portion that can be seen from the outside, that is, a portion 24f that covers the top surface of the top plate 22 and the top plate 2
And a portion 24g covering the second end face.
For this reason, the boiled-spilled liquid which has entered from the joint portion 29 of the top plate frame and has reached the inner surface of the top plate frame 24 does not have the back surface portion of the top plate 22 of the top plate frame 24 formed thereon. As shown by, it hangs down and comes out of the main body, so that it does not leak into the main body lower case 40. In this way, it is possible to prevent the components arranged inside the main body lower case 40 from being attacked by boiling water or the like.

Further, the embodiment of FIG. 4 shows the vicinity of the top frame joint (cross section e--e in FIG. 1) of the top frame 28 at the junction between the top plate 22 and the operation unit 23. . A seal member C35 is wound around the outer periphery of the top plate 22 and the operation unit 23 to form a top plate frame 28.
, And further pressed upward by a top plate receiver 37 having a sealing member D36 attached to the upper surface from the back surface side. Further, a second sealing member is provided between the mounting surfaces of the top plate frame 28 and the top plate receiver 37.
F41 is arranged. As shown in FIG. 5, the second seal member F41 is provided with small pieces near both ends of the top frame 28, that is, near the joint of the top frame, as shown in FIG. 5, and as shown in FIG. Some are provided on almost the entire surface except for both ends of the top plate frame 28. In such a configuration, the spilled liquid that has entered from the joint portion of the top plate frame tries to spread along the entire small space between the top plate frame 28 and the top plate receiver 37 in the longitudinal direction of the top plate frame 28. However, since the liquid is stopped by the seal member F41 on the path, the boiling-up liquid does not propagate in the longitudinal direction of the top plate frame 28. As a result, as shown by arrows in FIGS. 5 and 6, infiltration of the spilled liquid can be limited only to both ends of the top plate frame 28, that is, in the vicinity of all contact portions of the top plate frame. The effect of the spilling liquid on the components arranged in the can be eliminated. As in the present embodiment, the top plate frame not along the outer peripheral portion of the main body, that is, the top plate 22 and the operation unit
This is particularly effective for the top plate frame 28 at the 23 joints. The reason is that electric parts and the like inside the main body can be easily arranged in a portion that does not follow the outer peripheral portion of the main body, so that it is highly effective to prevent leakage of boiling water and the like in this portion.

In the embodiment shown in FIG. 7, the top plate frame 24 has a substantially L-shaped first top plate frame 24h covering the upper surface and the end surface of the top plate 22, and an inner surface of the first top plate frame 24h, for example. The second top plate frame 24i is partially connected and integrated by spot welding. Also, as shown in FIG. 8, the second top frame 24i is shorter than the first top frame 24h, and the short end of the top frame 24 is connected to the first top frame 24h and the first top frame 24h. There is a step j with the second top plate frame 24i. In such a configuration, the spilled liquid or the like that has intruded from the joint portion of the top plate frame penetrates into the back surface of the first top plate frame and attempts to spread the inner surface in the lateral direction. Since the frame and the second top plate frame are integrated by a point-like joint, there is a small gap between these two members, and the boiling-up liquid is absorbed by this small gap by capillary action. , When the amount increases, the 7th
As shown by an arrow in the figure, the leakage to the outside of the main body does not affect the components inside the main body.

Advantageous Effects of the Invention As described above, the present invention prevents the infiltration into the main body even if the spilling liquid or the like penetrates from the joint of the top plate frame of the top plate unit, or the top plate joining Since it can be limited to the vicinity of the part, it prevents the spilling liquid or the like from dropping and adhering to the electric components and the like in the main body, and furthermore, the life of the main body and the insulation deterioration are prevented.
