Description

  The present invention relates to a built-in heating cooker.

  In recent years, the restaurant industry has grown, and the number of places where built-in cooking equipment is installed in shops is increasing. It is a style in which cooking of pots, grilled meat, etc. is done with built-in cooking equipment installed on the customer's table.

  Most of such built-in cooking appliances are separated from a main body for cooking and heating and an operation unit for performing the operation, and the operation unit is attached to the side surface of the table or the end of the top surface. The two are connected by a cable, exchange electrical signals, and can be operated and heated. Under such circumstances, it is very important to improve the maintainability of products used in stores.

  Conventionally, as a configuration of this type of built-in heating cooker, for example, the main body and the operation part are connected by a cable, but the connection part of the cable is in the main part and the operation part, and each outlet is fixed by a bushing. There was something to be.

  In some cases, the heating unit, the power supply unit, and the operation unit are independent, and the cable from the heating unit and the operation unit is connected to the terminal portion of the power supply unit (see, for example, Patent Document 1).

  FIG. 12 is a perspective view of a conventional built-in heating cooker described in Patent Document 1, and FIG. 13 is a cross-sectional view of the conventional built-in cooking apparatus described in Patent Document 1. 12 and 13, there is a top plate support portion 2 that supports a top plate 1 made of a ceramic plate or the like on which a pan or the like is placed from below, and under the top plate 1 is a heating portion 3 that heats the pan. There is a control board A4 that controls energization of the heating unit 3, and both of them are supported by a board support 5.

  And there exists the box-shaped outer shell 6 supported so that those whole may be enclosed, and the main body is comprised. A cable A7 is connected to the control board A4, and the cable A7 is held and fixed by inserting a bushing A9 through the opening A8 from the opening A8 on the side surface of the outer shell 6 and inserting the bushing A9.

  On the other hand, the control board B11 is also provided in the operation unit 10 and is connected to the cable A7. The cable A7 is output from the opening B12 of the operation unit 10, and the cable A7 is held and fixed by the bushing B13 in the opening B12.

Thus, the main body and the operation unit are connected. By doing so, since the electrical connection portion so-called connector connection portion is not exposed to the outside of the main body, for example, even if water leaks from the gap on the table top surface and reaches the outside of the main body, the electrical connection portion directly There was little risk of breakdown or electric shock because water did not touch. Further, in the configuration in which the heating unit, the power supply unit, and the operation unit are independent, each unit can be taken out at the time of service.

A cover 41 that covers the connection portion C40 is fixed to the side surface of the outer shell 27 with claws and screws, with the connection portion A33 and the connection portion B37 as the connection portion C40. The cable A32 protrudes from a notch provided below the cover 41 to the outside.

  About the built-in heating cooker comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  Since only operations and actions that are different from the contents of the first embodiment will be described, the same contents are referred to the first embodiment. First, consider that water has leaked from the gap of the table 29. The water falls outside the outer shell 27 and falls into the connection portion C40 including the connection portion A33 and the connection portion B37.

  However, since the periphery of the connecting portion C40 is completely covered by the cover 41 and the side surface of the outer shell 27, water does not touch the connecting portion C40 (since the notch portion of the cover 41 is provided below). In the case of dripping water from above, there is no water adhesion to the connecting part C40).

  As described above, in the present embodiment, in the device in which the main body and the operation unit are separated via the cable, even if water enters from the table, the water touches the connection portion C (charging unit) of the main body. Therefore, it is possible to provide a highly reliable device that is free from failure and electric shock.

  Further, since the connection portion C40 is completely covered with the cover 41, when the main body is put into the opening hole 47 of the table at the time of installation, the connection portion C40 can be prevented from hitting the table, and the mechanical portion of the connection portion after the installation can be prevented. It can also be protected.

  Moreover, although demonstrated here on the side of the outer shell, the same effect can be obtained by attaching a cover to the bottom surface.

  In addition, since the connection part C is covered with a cover, the role which mechanically protects the connection part C which has an electrical connection part can also be performed.

  Further, the cover may be fixed not only by fastening the claws and screws but also by fixing only the claws. Then, it is very easy to attach and detach the cover.

  In addition, the cable A is effective from the bottom surface of the cover as described here in terms of water adhesion and installation of the main body, but depending on the configuration, even if the cable A is taken out from the side surface of the cover, Similar effects can be obtained.

  About the built-in heating cooker comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  Since only operations and actions that are different from the contents of the first embodiment will be described, the same contents are referred to the first embodiment. First, it is assumed that the cable A32 is slack and the cable A32 is accidentally pulled. However, since the cable A32 is fixed to the bottom surface of the outer shell 27 by the fixing member 42, the stress is applied only to the fixing member 42.

  That is, since the electrically connected connection portion C40 is not stressed, the electrical connection portion does not come off. Therefore, a phenomenon such as contact failure does not occur.

  As described above, in the present embodiment, the cable A is fixed to the outer side surface or the bottom surface by the fixing member, so that the connection part is poorly connected in the device in which the main body and the operation part are separated via the cable. It is possible to provide a highly reliable device that does not occur.

  Here, although the fixing member is attached to the outer bottom surface, the same effect can be obtained even if attached to the outer side surface.

  Further, the fixing member may be a resin or a metal as long as it is treated so as not to damage the cable (R shape, curling, hemming bending, etc.).

  Further, the same effect can be obtained by fastening the fixing member not only with screws and claws but also with two screws.

(Embodiment 4)
FIG. 8 is a perspective view of a built-in heating cooker according to the fourth embodiment of the present invention.

  In FIG. 8, the basic configuration is the same as that of the first embodiment, and therefore different parts of the configuration will be described. The cable A43 connecting the main body 28 operation unit 30 is formed of only signal lines (0.5 sq or less) for performing communication between them.

  About the built-in heating cooker comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  Since only operations and actions that are different from the contents of the first embodiment will be described, the same contents are referred to the first embodiment. First, the case where the cable A43 is replaced will be described.

  At that time, since the cable A43 is composed of only a plurality of thin signal lines, the cable A43 is as thin as about 8 mm even if it is more combined. In addition, since there is no thick 2sq through which a large current flows, even if there is a half insertion at the connection portion C40 and there is an increase in contact resistance, abnormalities such as heat generation and smoke generation do not occur and it is safe (contact It is almost impossible to energize).

  As described above, in the present embodiment, the cable A is configured only by a signal line that conducts only a minute current, so that the main body and the operation unit are separated from each other through the cable. It is possible to provide highly reliable equipment that is easy to perform at the time of service and is safe.

FIG. 9 is a perspective view of a built-in heating cooker according to a fifth embodiment of the present invention, FIG. 10 is a detailed sectional view of a built-in heating cooker according to a fifth embodiment of the present invention, and FIG. FIG. 10 is a cross-sectional view when the built-in heating cooker according to the fifth embodiment of the present invention is installed.

  9 to 11, the basic configuration is the same as that of the first embodiment, so the first embodiment is referred to. The corner edges 44 at the four corners of the bottom surface of the metal outer shell 27 are made of resin, and a protective member 45 having a smooth appearance is fitted and attached to a hole provided in the outer shell 27.

  “Smooth appearance” means a shape that has no edge and is rounded on the side where the surface of the appearance is applied (a shape that does not cause scratches even if it hits).

  About the built-in heating cooker comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  Regarding the operation and the action, the parts different from the contents of the first embodiment will be described. For the same contents, refer to the first embodiment. First, the installation state on the table 29 will be described. The outer shell 27 is made of metal made of nonflammable iron in order to ensure safety against smoke and fire from the main body 28. When the outer shell 27 is made, it is press-molded.

  Therefore, corner edges 44 are inevitably formed at the corners of the bends. Thus, the cable A32 exits the connection portion C40 and is connected to the operation portion 30. In the meantime, the cable A32 is basically fixed to the back surface of the table 29 with a clip or the like, but may not be fixed. At this time, the cable A32 may be in contact with the outer 27 corner edges 44 while hanging.

  If the cable A32 that performs electrical communication touches the corner edge 44, the insulation of the cable A32 is broken or broken and the insulation is broken. However, since the protective member 45 having a smooth appearance made of resin is attached to the corner edge 44 of the outer shell 27, the covering is not damaged even when the cable A32 contacts. The product performance can be ensured.

  Further, since the product is installed on the table, the knee 46 may come close to the bottom surface of the main body 28 when a person sits around the table. At that time, the corner edge 44 of the outer shell 27 is protected by the protective member 45, so that even if the knee 46 hits, it is possible to enjoy a meal safely without being injured.

  As described above, in the present embodiment, the main body and the operation unit are separated via the cable by fixing the protective member having a smooth appearance to at least one of the four corner edges of the outer bottom surface. In addition, it is possible to provide a reliable device that does not damage the cable and a safe device that does not cause injury during meals.

  In addition, although the four protective members are described here, they may be configured at positions corresponding to the corner edge portions. There is no limit to the number, and even if there is a corner edge, if you do not want to hit it with another method such as a partition plate, only place where people and cables are likely to hit. The same effect can be obtained.

Also, the corner edge does not stick to the bottom surface, it may be where the side surface is generated, it is not limited to only the corner edge that can be bent, etc., but it is also a protective member at the edge part such as a notch claw or cutting, a pointed screw etc. The same effect can be obtained by providing.

  Further, here, the protection member is mounted by fitting two claws of the protection member into the outer hole, but may be configured so as not to be easily removed by fastening with screws.

  The material of the protective member is not limited to resin, but may be rubber such as silicon, or may be a metal (iron, aluminum, etc.) having a smooth appearance as created by shaving.

  As described above, the built-in heating cooker according to the present invention can be applied to applications such as a remote control device (massage machine, personal computer) in which a main body and an operation unit are separated via a cable.
