It is intended to provide a heating device with higher safety for the younger by making it impossible to open the door in a state where it is in a heated state.

  In order to achieve the above object, the present invention provides a heating chamber, heating means for heating an object to be heated in the heating chamber, a door for opening and closing the heating chamber, an operation unit for controlling driving of the heating means, and a door It is configured to prevent inadvertent opening of the door by a lock mechanism using a hook that suppresses the opening of the door.

  Further, the knob for operating the lock mechanism is configured to be concealed by the storage front plate by closing the rotary storage type operation unit.

  As a result, it is possible to reduce the risk of danger to the user by providing a mechanism that cannot open the door carelessly.

  The present invention includes a heating chamber, a heating unit that heats an object to be heated in the heating chamber, a door that opens and closes the heating chamber, an operation unit that controls driving of the heating unit, and a hook that suppresses opening of the door. The knob is configured to prevent the door from being inadvertently opened by closing the stowable operation portion so as to be invisible from the outside.

  As a result, a mechanism that cannot open the door carelessly can reduce the danger to the user.

  The first invention is a vertical opening door provided on the front surface of the heating chamber in which the object to be heated is stored, and a rotary storage type operation which is provided on the front side of the heating chamber and sets the heating condition of the object to be heated. When the sliding hook that is provided on the operation portion holding frame and is linked to the operation knob is lowered, the tip of the hook is inserted into the upper surface hole of the vertical opening door that is arranged immediately below the operation portion, and the vertical opening door is A slide-type locking mechanism for locking is provided. Thereby, it is set as the structure which restrains the motion of a door and prevents inadvertent opening of a door.

  According to a second invention, in the first invention, when the rotary storage type operation unit is stored, the front knob of the rotary storage type operation unit hides the operation knob linked to the slide type hook. This can prevent the door from being opened carelessly.

  According to a third invention, in the first invention, even if the door is closed in a state where the hook has a structure in which the hook is pushed up by the vertically opened door closed by lowering the front edge of the hook, When the hook is pushed up, breakage of the hook or the door can be prevented.

  According to a fourth invention, in the third invention, the hook pushed up when closing the vertical opening door is fitted into the hole on the upper surface of the door by its own weight when the vertical opening door is closed, and is automatically locked. It is. Thereby, reliable door locking can be realized.

  Embodiments of the present invention will be described below with reference to the drawings. Note that the present invention is not limited to the embodiments.

  FIG. 1 is a schematic configuration diagram of a heating device according to an embodiment of the present invention. FIGS. 2A and 2B are a front view and a side view, respectively, of the heating device in the present embodiment.

  FIG. 3 shows a configuration in which the knob 7 of the hook 5 is hidden by the hook 5 that restricts opening and closing of the door of the heating device and the operation unit front plate 10 in the present embodiment. FIG. 3B shows a state where the operation unit front plate 10 is opened, and FIG. 3B shows a state where the operation unit front plate 10 is closed.

  FIG. 4 shows the relationship between the door and the detailed shape of the hook 5 that restricts the opening and closing of the door of the heating device in this embodiment. FIG. 4 (a) shows that the hook 5 fits into the insertion hole 6. FIG. 2B shows a state where the hooks 5 are fitted in the insertion holes 6.

  In these drawings, the heating device main body 1 is made on the assumption that it is installed under a range, so that the user can touch only from the front surface of the heating device at the time of installation. This heating apparatus is provided with a heating chamber 2 for heating an object to be heated by a heater or a heating means such as high frequency or steam.

  The door 3 that opens and closes the heating chamber 2 is provided with a handle 4 at the upper center of the door and can be opened and closed by the user. An insertion hole 6 for restricting the movement of opening the door by the hook 5 is provided on the upper surface of the door.

The hook 5 is provided with a knob 7 for the user to freely adjust the position of the hook 5 to lock, release or move it. When the user slides the knob 7 downward, the hook 5 is inserted into the insertion hole 6 of the door, and the movement of the door 3 is restricted. The operation unit 8 provided above the door of the apparatus main body is for the user to operate the heating means and the like.

  The operation unit 8 is a rotary storage type, and the operation unit 8 can be rotated and stored in the storage unit 9 when the user does not want to operate the device.

  At this time, the front plate 10 when the operation unit 8 is closed is extended to the front of the knob 7. As a result, in the state where the operation unit 8 is stored in the storage unit 9, the knob 7 is moved by the front plate 10. It is concealed and it is difficult for a user (especially a young person) to easily operate the knob 7 to release the restraint of the door 3.

  On the other hand, the user operates the knob 7 by mistake and closes the door 3 while the hook 5 is lowered, so that the hook 5 does not collide with the door 3 and the hook 5 is not broken. The edge is provided with a tapered shape 11 that is inclined backward.

  As a result, even when the door 3 is closed with the hook 5 lowered, the hook 5 is pushed up along the taper shape 11 by the force of closing the edge of the door 3 to prevent the hook 5 from being broken.

  Further, when the hook 5 is always lowered by its own weight, when the door 3 is closed, the hook 5 is once pushed up by the tapered shape 11 due to the taper shape 11. It is also possible to adopt a configuration in which the door 5 is inserted and the hook 5 is automatically restrained by closing the door 3. Thereby, even if a user forgets to operate the hook 5, the door 3 is restrained and the possibility that the door 3 is opened carelessly and is in danger can be reduced.

  In the above embodiment, it goes without saying that the functions can be combined and used synergistically to reduce hot air from the heating chamber.

  Although the heating device of the present invention can be restrained against the opening of the door in spite of being installed at a low position, it is exposed to danger by opening the door, particularly by a young person. Therefore, it can be used for applications such as a microwave oven and an electric oven installed under the range.
