Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a deep fryer, and more particularly to a deep fryer equipped with means for automatically extinguishing boiling frying oil when it ignites. This is related.

[Conventional technology]

As is generally known, when using a tempura pot, if the tempura oil that is heated to a high temperature and boils in the pot during cooking exceeds a certain temperature, it will ignite and cause a fire. Because there is a risk of

Conventionally, when cooking using a tempura pot, it has been said that the golden rule is to avoid leaving the cooking area as much as possible and to constantly monitor the condition of the tempura oil.

[Problem that the invention seeks to solve]

However, as a practical matter, it is impossible for a cook to leave the tempura pot unattended for even a moment during the cooking process, and for this reason, there are many fires caused by ignition of tempura oil.

In order to solve these conventional problems, this invention automatically fits a lid plate onto the pot body when tempura oil ignites, and this operation cuts off the supply of primary air for combustion. It is designed to have a fire extinguishing effect.

[Means for solving problems]

That is, the present invention provides a pot body, a lid plate pivotably attached to the negative side of the pot body, and a lid plate that holds the lid plate in an open state and a closed state, respectively, and a closed state. Each holding means and an ignition detection means for detecting ignition of tempura oil inside the pot body when the lid plate is opened and notifying the outside as necessary, and the ignition detection means
This deep fryer is characterized in that a lid plate can be operated from an open state to a closed state with respect to the main body of the frying pan.

〔Example〕

Hereinafter, the first embodiment of the deep fryer according to the present invention will be described.
This will be explained in detail with reference to the drawings to FIG.

FIGS. 1 and 2 are a perspective view and a side view showing how the deep fryer according to this embodiment is used, and FIGS. 3 and 4 are perspective views showing the configuration of the main parts thereof, respectively.

(In each of these figures, the deep fryer according to this embodiment has a handle 2a formed in a planar angular shape,
A pot body 1 with 2b and one handle 2 of this pot body 1
It has a lid plate 3 pivotally attached to the a side with a hinge 4.4 so as to be freely openable and closable, and a handle 5 for opening and closing operation incorporating a control section 6 for controlling the operation to be described later on the upper surface of the lid plate 3. At the same time as attachment, a suction groove 7 is formed in the handle 5. The lid plate 3 is formed to have an opening/closing angle of approximately 80'' with respect to the horizontal plane of the upper end of the pot body 1, so that the lid plate 3 can easily fall down due to the weight of the handle 5, and the detection by the detector 15 described later is more accurate. It should work properly.

Further, a support rod 8 fixed to one handle 2a side of the pot body 1 is provided with a suction rod 9 whose base part can be pivoted to freely raise and lower and can be appropriately locked in the upright position. On the other handle 2b side of the main body 1, there is a permanent magnet 1 with a strong attraction force.
0 so that the suction pieces 11 placed on the corresponding portions of the lid plate 3 can be suctioned.

A control unit 6 incorporated into the opening/closing handle 5
These include a power source 12, a power switch 13, a control circuit 14, and the lid plate 3 for detecting ignition of tempura oil.
A detector 15 protrudes inward, an electromagnet 1B in contact with the suction groove 7, and a buzzer 17 that notifies ignition of tempura oil.
When the electromagnet 18 is energized, the suction groove 7 of the cover plate 3 is attracted to the suction rod 9, and the electromagnet 18 can be supported in the opening position.

Therefore, in this embodiment, a deep fryer is used as shown in FIGS. 1 and 2.

Turn on the power switch 13 and leave the suction rod 9 in the upright position, open the lid 3 from the pot body 1, and suction the suction groove 7 that is excited by the electromagnet 16. By adhering to the rod 9, the lid body 3 can be supported in the opening position.

While it is being used like this, i.e. cooking,
If the tempura oil heated to a high temperature inside the pot body 1 ignites for some reason, the temperature of the flame is detected by the detector 15 protruding inside the lid plate 3, and the detected temperature is detected. When the temperature of the device 15 itself or the control circuit 14 is higher than a predetermined temperature, the control output from the control circuit 14 demagnetizes the electromagnet 1B, thereby causing the suction groove 7 to be attached to the suction rod 8. The suction is released, and the lid 3 held in the opening position is automatically covered over the pot body l by its own weight around the hinge 4.4, and at the same time, the permanent magnet 10 on the pot body 1 side Then, the suction piece 11 of the lid plate 3 is attracted, and the pot body 1 is hermetically fitted with the lid plate 3, thereby cutting off the supply of primary air into the pot and extinguishing the fire. By energizing and making a sound, it is possible to notify the outside that tempura oil has ignited.

In the case of the above embodiment, the power source 12 is a battery or a commercial AC power source rectified into direct current.
Alternatively, a thermoelectric power generation element may be used, and the power switch 13 is automatically turned on by, for example, opening the lid plate 3 from the pot body l, and the buzzer 1 is turned on.
7 may be energized for a limited period of time, and furthermore, the notification by the buzzer 17 may be adopted as necessary.Furthermore, the shape of the cover plate 3 may be changed so that the edge is rounded as in the embodiment. In addition to the formed one, it can also be a simple flat plate.
Furthermore, a sealing material may be fixed to the outer periphery of the lid plate 3 as required.

Furthermore, in the embodiment described above, the holding of the lid plate 3 in the open position with respect to the pot body l is carried out by the suction groove 7 excited by the electromagnet 16.
The electromagnet 1B is demagnetized by detecting the ignition of the tempura oil by the detector 15, so that the close fitting of the lid plate 3 to the pot body 1 in the event of ignition is caused by adsorption to the suction rod 8. However, for example, a bimetal may be used which is activated by detecting ignition, and the lid plate 3 may be operated in conjunction with the activation of this bimetal, or the lid plate 3 may be opened. The holding position and the cover actuating means may be performed by a shape memory alloy shaped in accordance with the ignition detection temperature.

〔Effect of the invention〕

As described in detail above, according to the present invention, means for holding the lid plate in the open and closed states are provided for the pot body, l, and when ignition of the tempura oil is detected, the lid plate is closed. Since it can be automatically operated from the open state to the closed state, even if you neglect to monitor the tempura oil during cooking and it catches fire, the tempura pot will be automatically sealed and fitted with the lid plate. , the fire can be extinguished by immediately cutting off the supply of primary air into the pot, thereby preventing a fire caused by the ignition of the tempura oil, and, if necessary, using a buzzer etc. This system has features such as being able to notify the outside world 9 of the information, and having a simple configuration and easy implementation.
