Description

  The present invention relates to a drawer-type heating cooker in which a drawer body can be drawn out and housed with respect to a cooker body, and an opening of a heating chamber can be sealed with an opening / closing door in the housed state.

  Conventionally, a drawer body on which an object to be heated can be placed can be pulled out together with an opening / closing door with respect to the cooker body. A drawer-type heating cooker that can be closed is proposed (Patent Document 1, Patent Document 2). In this type of drawer-type heating cooker, an apparatus main body (cooker main body) having a cooking chamber (heating chamber) that accommodates an object to be heated, an open / close door that shuts off the cooking chamber from the outside air, and interlocked with the open / close door And a heating container (drawer) on which a bottom plate or an object to be cooked can be placed. More specifically, the bottom plate or the heating container is smoothly slid by the sliding mechanism, and the rotation output of the motor is transmitted to the sliding mechanism via a transmission means such as a rack and pinion mechanism. The main body can be pulled out or moved in the receiving direction. In a state where the bottom plate or the heating container is accommodated in the device main body, the open / close door blocks the cooking chamber from the outside air. The heating cooker described in Patent Document 2 forms a heating chamber for confining microwaves by covering the opening of the heating container having an opening formed in the upper part thereof and capable of being pulled out from the cooker main body with a lid portion. Leakage of radio waves is prevented by providing a choke groove between the opening peripheral edge of the lip and the lid.

In this type of drawer-type cooking device, water vapor is generated from the object to be heated during cooking of the object to be heated such as food. The generated water vapor flows in the vicinity of the handle of the open / close door while riding on the air flow in the heating chamber, and is cooled at that time to cause dew on the handle. Such dew drops the appearance quality after cooking, and the arm or sleeve that touches the handle when the heated object is taken out gets wet with dew. When the discharge of water vapor is concentrated at an exhaust port provided at a position different from the vicinity of the handle, a noticeable dew is observed at that portion.
Japanese Patent Application Laid-Open No. 3-45820 (page 2, lower left column, line 6 to page 3, upper right column, line 16, FIG. 1 to FIG. 1) Japanese Patent Laid-Open No. 11-237053 (paragraphs [0029] to [0032], FIG. 1)

  Therefore, in the drawer-type heating cooker, when the door is closed, water vapor generated from an object to be heated in the heating chamber is completely closed between the handle provided at the upper end of the door and the opening edge of the cooker body. However, there is a problem to be solved in that it effectively prevents a gap from flowing through a difficult gap.

  An object of the present invention is to prevent water vapor generated from an object to be heated in the heating chamber from flowing between the upper end of the door and the opening edge of the cooker body, and the water vapor is condensed on the handle. It is an object of the present invention to provide a pull-out heating cooker that can prevent sticking.

  In order to solve the above problems, a drawer-type heating cooker according to the present invention is capable of pulling out a drawer body on which an object to be heated can be placed, together with an opening / closing door, to the cooker body, and using the drawer body as the cooker body. A drawer-type heating cooker that can close the opening of the heating chamber with the open / close door in the housed state in which the open / close operation handle is provided at the top of the open / close door A packing is disposed at the edge of the opening of the cooker body so as to close the space between the handle and the handle when the door is closed, and the lower part of the door opens into the heating chamber. An exhaust port is formed.

  In the drawer-type heating cooker according to the present invention, it is difficult to completely close between the opening / closing operation handle provided at the upper part of the open / close door and the opening of the cooker body when the open / close door is closed. Although it is unavoidable that a slight gap is generated, packing is disposed at the edge of the opening of the cooker body so as to close the gap. Therefore, when the door is closed, the water vapor generated when cooking the object to be heated in the heating chamber is sealed with packing so as not to flow into the gap. Therefore, it is possible to prevent dew condensation due to condensation on the handle. Moreover, since the packing is disposed on the opening side, even if the door is opened and closed, what appears on the front side is the normally flat upper surface of the handle. The packing does not appear on the front side together with the door.

  In this drawer-type heating cooker, the handle includes a handle body attached to an upper part of the main body of the open / close door, and a latch that extends from the handle main body to the front side of the open / close door and can be hooked with a finger for opening and closing operations. A portion. The handle body is attached to the upper part of the main body of the door and defines the upper end surface of the door. A drawer can be pulled out by placing a finger on a locking portion extending from the handle body to the front side of the door. Further, since the handle is viewed from above, an element of the decorative board that can be replaced according to the user's preference or the like can be incorporated in the opening / closing door.

  In this drawer-type heating cooker, the packing includes an attachment portion that is attached to a rear edge portion of the opening, and a sealing portion that extends downward from the attachment portion and can come into contact with the handle. be able to. As for the packing, the mounting part is attached to the inner edge of the edge of the opening, so the packing is easy to attach and remove from the back side of the opening and has good workability during assembly and maintenance. It is. Furthermore, the attachment part of packing is not visible from the front side of the heating cooker, and a simple appearance can be maintained. When the open / close door is closed, the sealing portion extending downward from the attachment portion contacts the handle provided on the open / close door, so that the water vapor passes between the edge of the opening and the handle to the outside. It will not flow out.

  In the drawer-type heating cooker in which the packing includes an attachment portion and a sealing portion, the sealing portion is deformed by the upper end deep portion of the handle that is pushed in to close the open / close door, and the upper end deep portion is formed. It is preferable to make it elastic. When the opening / closing door is pushed in and the opening is closed, the sealing portion of the packing is deformed by the back end of the upper end of the handle at the final stage of the closing process. Since the sealing portion is brought into contact with the handle with an elastic force due to the return of deformation, the gap between the handle and the handle can be strongly sealed.

  In this drawer-type heating cooker, the exhaust port is a punching hole having a small opening ratio and a small diameter, so that foreign substances and insects can be prevented from entering while exhausting.

  As described above, the drawer-type cooking device according to the present invention is provided with a handle for opening / closing operation at the upper part of the opening / closing door, and closes the space between the handle in the closed state of the opening / closing door at the edge of the opening of the cooker body. Since the packing is arranged in the form and an exhaust port communicating with the heating chamber is formed in the lower part of the opening / closing door, water vapor generated from the heated object in the heating chamber is cooked with the upper end portion of the opening / closing door. The packing prevents the water from flowing through the opening edge of the container body, thereby preventing water vapor from condensing on the handle and, as a result, preventing the upper part of the handle from becoming dewed. . In addition, since the packing is attached to the opening side, it can be easily attached and removed during assembly and maintenance, and it can be opened and closed without being visible from the outside when the door is opened in normal use. The simplicity and cleanliness of the door can be maintained.
