Description

  The present invention relates to a grill door provided on a stove with a grill to open and close a front opening of a grill cabinet.

  The grill door generally includes a steel plate back plate, a front panel provided on the front side of the back plate, and a handle provided on the front side of the front panel. Conventionally, a grill door is known in which a front panel is made of resin and a handle is integrally formed with the front panel (see, for example, Patent Document 1). In this case, a window glass covering a window hole opened in the upper half is mounted on the front surface of the upper half of the back plate, and a front panel made of resin is provided on the front side of the lower half of the back plate. Yes.

By the way, recently, a high-quality stove has come to be preferred. Here, if the front panel of the grill door is made of resin, it gives a cheap feeling and impairs the sense of quality. In this case, it is conceivable that the front panel and the handle are made of aluminum, and a high-class feeling is brought about by the luster of aluminum. However, this increases the thermal conductivity of the front panel and the handle, and the temperature of the handle increases during use of the grill, resulting in poor usability.
Japanese Utility Model Publication No. 7-33043 (FIGS. 2 and 3)

  In view of the above points, an object of the present invention is to provide an easy-to-use grill door that uses aluminum to provide a high-class feeling and can suppress the temperature rise of the handle.

In order to solve the above-mentioned problems, the present invention is a grill door provided on a stove with a grill to open and close the front opening of a grill cabinet, and is provided on a steel plate back plate and on the front side of the back plate. A front panel and a handle provided on the front side of the front panel are provided , and a window glass covering a window hole established in the upper half is mounted on the front surface of the upper half of the back plate, A front panel is provided on the front side, and an upper cover portion that covers the upper front surface of the window glass and extends upward from the upper end surface of the back plate, and a front position above the upper edge portion of the front opening of the grill cabinet. in the upper frame provided shall comprise a eaves portion from the opening extending rearward, the front panel is composed of a base member made of resin is attached to the front surface of the back plate, and aluminum decorative plate covering a front face of the base member An aluminum handle is connected to the base member With the, the upper frame, and the upper cover portion, is formed by extrusion molding material of aluminum having a tongue portion which protrudes from the vertically intermediate portion of the rear surface of the upper cover portion rearwardly seated on the upper end surface of the back plate The upper frame body and a steel plate presser plate that fixes the tongue piece part between the upper end surface of the back plate, and has a two-member structure. A hemming portion that is folded back to the lower surface is formed on the side edge, and the hemming portion is brought into contact with the upper surface of the tongue piece .

  According to the above configuration, the appearance of the aluminum decorative plate and the aluminum handle appear, and a high-class feeling is created. In addition, a resin base member is interposed between the back plate and the handle, and heat conduction from the back plate to the handle is suppressed due to the low thermal conductivity of the resin. Therefore, it is possible to prevent the temperature of the handle from rising during use of the grill and to improve usability.

  In addition, if the base member is formed with a protrusion protruding forward through the decorative plate and a handle is connected to the protrusion, the heat conduction path length by the base member (resin) between the back plate and the handle is the protrusion. Thus, the temperature rise of the handle is more effectively suppressed. If the peripheral surface of the protrusion is covered with an aluminum cover member, the impression that the protrusion is also made of aluminum can be given, and the appearance is not impaired.

  By the way, when the front glass is installed on the front side of the lower half of the back plate when the window glass covering the window hole established in the upper half is installed on the front surface of the upper half of the back plate, Provide an upper frame that covers the upper front surface of the window glass and has an upper cover portion that extends upward from the upper end surface of the back plate and a flange portion that is located above the upper edge of the front opening of the grill cabinet and extends rearward from the front opening. There is. The upper cover part is for concealing the engaging part of the upper edge of the window glass and the back plate and the upper end of the back plate to improve the appearance, and the collar part is inside the grill cabinet when the grill door is half-closed. This prevents the hot air from leaking upward from the gap between the front opening and the grill door.

  Here, when the front surface of the front panel is covered with an aluminum decorative plate and the handle is also made of aluminum as in the present invention, it is desired that the upper cover part is made of aluminum to obtain a sense of unity in design. In this case, it is conceivable that the upper cover portion is constituted by a flat plate made of aluminum, and this flat plate is screwed to the upper end portion of the back plate, but in this case, the screw appears on the appearance and the appearance is impaired. On the other hand, the upper cover part is formed of aluminum extrusion molding material, and the tongue piece part that protrudes rearward from the vertical middle part of the back surface of the upper cover part and sits on the upper end surface of the back plate is integrally formed on the upper cover part. If the upper cover portion is screwed to the upper end surface of the back plate at the tongue piece portion, the screw is hidden behind the upper cover portion and does not appear in the appearance, and the appearance is improved. And the upper frame of 1 member structure provided with an upper cover part and a collar part can be obtained by extending the said collar part integrally from the rear edge of a tongue piece part. However, in this case, heat from the hot air leaking from the inside of the grill when the grill door is half-closed is transferred to the upper cover portion through the flange portion, and the upper cover portion becomes high temperature.

Therefore, in the present invention, as described above, the upper frame is made of aluminum having the upper cover portion and the tongue piece portion that protrudes rearward from the middle portion in the vertical direction on the back surface of the upper cover portion and sits on the upper end surface of the back plate. The upper frame body made of extruded material and a steel plate presser plate that fixes the tongue piece between the upper end surface of the back plate and has a two-member structure. At the same time, a hemming portion folded back to the lower surface is formed on the side edge of the presser plate, and the hemming portion is brought into contact with the upper surface of the tongue piece. According to this, a gap corresponding to the thickness of the hemming portion is vacant between the tongue piece portion and the presser plate, and heat is hardly transmitted from the presser plate to the tongue piece portion (upper frame main body). Therefore, heat conduction from the flange portion to the upper cover portion is effectively suppressed, and the upper cover portion can be prevented from becoming hot when the grill door is half-closed.

  Further, when the grill door is half-closed, hot air may flow from the lower side of the flange part to the upper side and the hot air may flow toward the upper half part of the upper cover part. In this case, if a rising portion that covers the upper half of the upper cover portion from behind is formed at the front portion of the presser plate, the upper portion due to the hot air flowing toward the upper half portion of the upper cover portion is formed. Advantageously, heating of the half can be prevented.

In addition, the rear surface of the handle 64 is formed as a convex surface and the tip end surface of the protrusion 636 is formed as a concave surface, so that the handle 64 can be sat down with respect to the protrusion 636.

  The upper frame 65 is composed of two members: an upper frame main body 651 formed of an aluminum extrusion molding material, and a press plate 652 made of a steel plate. The upper frame main body 651 covers the upper front surface of the window glass 62 and extends upward from the upper end surface of the back plate 61 (the upper surface of the upper sash portion 613), and from the middle in the vertical direction on the back surface of the upper cover portion 653. A tongue piece 654 that protrudes rearward and sits on the upper surface of the upper sash 613. The pressing plate 652 is provided to fix the tongue piece 654 so as to be sandwiched between the upper sash portion 613 and the rear edge thereof is located above the upper edge portion of the front opening 4b of the grill box 4a. A flange portion 655 extending rearward from the front opening 4b is integrally extended. Further, a rising portion 656 is formed at the front portion of the pressing plate 652 to cover the upper half portion (portion above the tongue piece portion 654) of the upper cover portion 653 with a gap from behind.

  Screw holes 613a are formed in the upper sash portion 613 in the vicinity of the left and right ends, and attachment holes 652a and 654a corresponding to the screw holes 613a are formed in the presser plate 652 and the tongue piece portion 654. Yes. Then, as shown in FIG. 5, the presser plate 652 and the tongue piece 654 are fastened together with the upper sash portion 613 by screwing the screw 657 into the screw hole 613 a from above through the mounting holes 652 a and 654 a. . Here, a hemming portion 652b that is folded back to the lower surface side is formed on the side edge of the presser plate 652. Therefore, when the hemming portion 652b is brought into contact with the upper surface of the tongue piece portion 654, a gap corresponding to the thickness of the hemming portion 652b is formed between the presser plate 652 and the tongue piece portion 654. It should be noted that in the place where the attachment hole 652a is formed, the presser plate 652 is recessed downward so that the place comes into contact with the upper surface of the tongue piece 654. Further, a concave portion 654b is formed in the intermediate portion in the horizontal direction of the tongue piece portion 654 to reduce the contact area with the upper sash portion 613, and heat conduction from the back plate 61 to the upper frame body 651 is performed. It is trying to be suppressed.

  According to the above configuration, all the members excluding the window glass 62 are exposed on the front surface of the grill door 6, that is, the aluminum decorative plate 632, the aluminum handle 64, and the aluminum upper plate. The cover portion 653 becomes a high-quality feeling. Further, unlike the case where the front panel 63 is entirely made of aluminum, a resin base member 631 is interposed between the back plate 61 and the handle 64, and therefore the handle is separated from the back plate 61 due to the low thermal conductivity of the resin. The heat conduction to 64 is suppressed. In particular, since the handle 64 is connected to the protrusion 636 formed on the base member 631, the heat conduction path length by the base member 631 (resin) between the back plate 61 and the handle 64 is equal to the protrusion 636. It becomes long and the temperature rise of the handle 64 is suppressed more effectively. As a result, the temperature of the handle 64 during use of the grill is suppressed, improving usability. In addition, since the peripheral surface of the protrusion part 636 is covered with the cover member 636a made from aluminum, the impression that the protrusion part 636 is also made from aluminum can be given, and appearance is not impaired.

  Further, even if a gap is formed between the front opening 4b and the grill door 6 when the grill door 6 is in a semi-closed state, the gap is covered from above by the flange portion 655 of the presser plate 652, so Can be prevented from leaking upward from the gap between the front opening 4 b and the grill door 6. In this case, although the flange portion 655 becomes high temperature, a gap due to the hemming portion 652b of the presser plate 652 is vacant between the presser plate 652 and the tongue piece 654, so that the tongue piece 654 (upper frame) from the presser plate 652 is provided. Heat is not easily transmitted to the main body 651). As a result, heat conduction from the flange portion 655 to the upper cover portion 653 is effectively suppressed. Further, when the grill door 6 is semi-closed, hot air may flow from the lower side of the flange portion 655 to the upper side and flow toward the upper half portion of the upper cover portion 653. The rising portion 656 functions as a heat shield wall, and heating of the upper half portion of the upper cover portion 653 by hot air is effectively prevented. Accordingly, the upper cover 653 can be prevented from becoming hot when the grill door 6 is half closed.

  As mentioned above, although embodiment which applied this invention to the grill door 6 provided in a drop-in type stove with a grill was described, this invention is applicable similarly to the grill door provided in a tabletop type stove with a grill.
