Description

  The present invention relates to a handle for an opening / closing door of a heating cooker.

  In recent years, cooking devices such as an oven microwave oven have become indispensable devices in daily life. Also, the frequency of daily use is high, and it is not uncommon for the door to be opened and closed several times a day. It is a great merit for the user to easily open and close the door. In addition, the opening and closing of doors that are easy for healthy people is not always easy for the elderly and the physically handicapped, and the development of doors that can be opened and closed easily is awaited.

  2. Description of the Related Art Conventionally, a heating cooker such as an oven microwave oven has a structure in which an opening / closing handle is attached to an upper part of a front surface of an opening / closing door in a so-called vertical opening door that opens and closes in the vertical direction. In the conventional example shown in FIG. 6, the grip handle 13 is attached to the upper front portion of the open / close door 14 in parallel to the floor surface.

  When the user opens the opening / closing door 14, the user grasps the grip portion of the grip handle 13 and pushes it down along the rotational movement of the opening / closing door 14 while pulling it forward. When it becomes almost parallel to the floor surface, the stopper works and does not lower any more, and the weight of the opening / closing door 14 makes it stable in this state. The user must hold the grip portion of the grip handle 13 from the beginning of opening of the door 14 until the bottom end is in a stable state. If the user releases the door, the door 14 falls by its own weight and impacts the device. It is. Therefore, the user needs to bend the joint of the wrist holding the grip handle 13 according to the opening / closing angle of the opening / closing door 14. Further, when the opening / closing door 14 cannot be rotated only by bending the joint, it is necessary to slide or re-grip the grip handle 13. As described above, a complicated operation is required to open and close the open / close door 14, and there are cases in which the door cannot be opened and closed smoothly if it is in a hurry or if it is handled roughly. Moreover, in the heating cooker with a heater, the surface of the door glass window 15 may become high temperature, and care was required so that a hand and a finger might not hit a glass surface. Therefore, it is not always convenient for the elderly and the handicapped who have difficulty in bending the wrist joint.

Attempts have also been made to alleviate the above disadvantages. For example, as shown in Patent Document 1, the handle can be rotated according to the opening and closing of the door, or the handle grip surface can be rotated, so that the user can open and close the door without sliding the palm of the hand. It has a simple structure. However, the problem has been reduced, but it has not disappeared. It is a big problem, and further improvement is desired for the elderly and the physically disabled.

  The problem to be solved by the present invention is to provide a cooking device that allows a user to open and close the door easily and safely. An object of the present invention is to realize an easy-to-use cooking device that can open and close the door easily and safely not only for healthy people but also for elderly people and physically handicapped people.

In order to solve the above-described conventional problems, a heating cooker according to the present invention opens and closes an opening / closing door for opening and closing food that is attached to the front surface of the heating cooker so as to be opened and closed and is opened and closed vertically. The rotating handle is configured by a structure protruding from the side surface of the opening / closing door, and the rotating handle freely rotates with respect to an axis perpendicular to the side surface of the opening / closing door. It is configured to move. Further, the rotary handle is formed on the left and right side surfaces of the open / close door, and has a cylindrical shape formed by molding a resin material.

  With this configuration, the cooking device of the present invention can provide a cooking device that is easy for the user to open and close the door and is safe. In a vertically opened door, the movement of the wrist joint of the user who grasps the rotary handle when the door is opened and closed can be eliminated, and the door can be opened and closed easily. In addition, when cooking in the oven, the rotating handle itself does not become hot, and hands and fingers do not touch the hot door glass window. It becomes a vessel. It is possible to provide a cooking device that is easy to use not only for healthy people but also for elderly people and people with physical disabilities.

  1st invention is equipped with the opening-and-closing door for putting in and out food which opens and closes in the up-and-down direction attached to the front of a cooking-by-heating machine, and the rotation handle which a user grasps in order to open and close the opening and closing, The rotary handle is composed of a structure protruding from the side surface of the open / close door, and the rotary handle is configured to freely rotate and move with respect to an axis perpendicular to the side surface of the open / close door. The door can be opened and closed without moving the wrist joint.

  In the second aspect of the present invention, the rotary handle is configured on both the left and right side surfaces of the opening / closing door, and the door can be opened and closed with either the left or right hand, which is convenient.

  According to a third aspect of the present invention, the rotary handle is formed of a resin molded product. Since the resin material has a lower thermal conductivity than metal, the rotary handle does not reach a high temperature even after cooking the heater and is safe to hold.

  In the fourth aspect of the invention, since the rotary handle has a columnar shape centering on the rotation axis perpendicular to the side surface of the opening / closing door, the user can easily grip and open / close the door.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the following embodiments.

(Embodiment 1)
FIG. 1 is a front view showing a state where an opening / closing door of a cooking device according to the present invention is closed. The cooking device includes a main body 1 of the cooking device, an open / close door 2 provided on the front surface of the main body 1 and opened and closed vertically, a door glass window 3 provided on the open / close door 2, an operation panel 4 provided on the lower portion of the open / close door 2, and a display. 5. A grip handle 6 provided at the upper front of the open / close door 2 and a rotary handle 7 provided at the upper left and right side surfaces of the open / close door 2. One rotary handle 7 is provided on each of the left and right sides of the door 2, but the structure and the mounting position are symmetrical with respect to the center of the door 2.

  FIG. 2 is a front view showing a state where the open / close door 2 of the cooking device is opened. The grip handle 6 is hidden under the open / close door 2 and is in a position where it is difficult for the user to grip. On the other hand, it can be seen that the rotary handle 7 is in a position where the user can easily grasp it even when the door 2 is opened.

FIG. 3 is a cross-sectional view of the main part showing the mounting structure of the rotary handle 7. A choke structure 8 that stops leakage of radio waves is formed in the open / close door 2. The choke structure 8 is hidden by a cover 9 so that a user cannot touch it for safety. The rotary handle 7 is attached to the side surface of the open / close door 2 with a mounting screw 10. A spring 12 is inserted between the opening / closing door 2 and the mounting screw 10, and the rotary handle 7 is always pressed lightly against the opening / closing door 2. With this configuration, the rotary handle 7 can freely rotate with respect to the door 2 around the shaft 11. The rotary handle 7 has a cylindrical shape with a corner around the shaft 11 dropped so that the user can easily grip it. The rotary handle 7 is made of a resin molded product that is less likely to transfer heat than metal.

  Next, the operation of the present embodiment will be described. FIG. 4 shows a state in which the user's right hand A grips the rotary handle 7 provided on the right side surface of the door 2 with the door 2 closed. In FIG. 4, the rotary handle 7 and the user's right hand A are separated from each other, but the user's right hand A is holding the rotary handle 7 in order to make the drawing easier to see. The user pulls the right hand A holding the rotary handle 7 horizontally in order to open the door 2. When pulled further, the rotary handle 7 is lowered according to the opening angle of the door 2. Although the gripped right hand A is also lowered, the rotary handle 7 is rotated, so that it is possible to move the wrist joint by simply bending the elbow, to slide the gripped position, or to keep opening without re-gripping. Further, since the rotary handle 7 is on the side surface of the open / close door 2, the right hand A does not hit another structure when grasping and during the opening / closing, and it is safe.

  FIG. 5 shows a state where the open / close door 2 is fully opened. Similarly, in FIG. 5, the rotary handle 7 and the user's right hand A are separated, but the right hand A holds the rotary handle 7. Since the rotary handle 7 rotates even when the open / close door 2 is fully opened, the user's right hand A holds the rotary handle 7 at the same wrist angle as the beginning of opening (the state shown in FIG. 4). The same applies to the case where the open / close door 2 is closed. The right hand A holding the rotary handle 7 can close the open / close door 2 without changing the angle of the wrist joint.

  In the above description, the case where the right rotating handle 7 configured on the right side surface of the opening / closing door 2 is operated with the right hand A of the user has been described, but the left rotating handle (illustrated) configured on the left side surface of the opening / closing door 2 is described. The effect is the same when the user's left hand (not shown) is operated.

  1 and 2, the rotary handle 7 is configured on both the left and right sides of the open / close door 2, but the user can conveniently open and close the door with either the left or right hand.

  Further, since the rotary handle 7 is configured on the side surface of the open / close door 2, there is no danger of touching the door glass window 3 when the user tries to grip the rotary handle 7. Therefore, even when the door glass window 3 is at a high temperature after cooking in an oven, it is not necessary to be careful not to touch the door glass window 3 as in the prior art.

  Furthermore, the rotary handle 7 is a resin molded product, has a low thermal conductivity, and is easy to use and safe at low temperatures when it is difficult to transfer heat from the cooking device. In addition, the rotary handle 7 has a cylindrical shape with a reduced corner and is easy to grip.

  This configuration eliminates the movement of the user's wrist joint when the door is opened and closed, allowing the door to be opened and closed easily, and safe cooking that prevents the hands and fingers from touching the door glass surface that is hot. It becomes a vessel. A safe and easy-to-use cooker can be provided not only for healthy people but also for elderly people and people with disabilities.

  As described above, according to the present invention, since the door can be opened and closed without moving the wrist joint, it can be widely applied to other devices having a vertically opened door. Therefore, it is possible to open and close the door safely even in general equipment where the front surface of the door is hot.
