Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a lid knob for a cooking device such as a pot, and more specifically, a knob for a lid of a cooking device such as a pot, and more specifically, a knob for a lid of a cooking device such as a pot. This invention relates to a pressure cooker lid knob that has the function of opening and closing.

[Conventional technology]

Traditionally, pressure cookers, i.e., pots that prevent water vapor from boiling in the pot from leaking outside, increase the pressure inside the pot to raise the boiling point, and cook food in a short time are widely used. . When cooking using a pressure cooker, the cooking process involves boiling the water in the pot before adding ingredients. In such cases, it would be helpful to have a way to notify that the water has boiled.
This prevents unnecessary overboiling and contributes to fuel savings.

[Purpose of the invention]

An object of the present invention is to provide a pressure cooker lid knob that can reliably notify that the pot has boiled, has a simple structure, can be easily disassembled and cleaned, and can easily and smoothly open and close the steam vent. It's in the middle of the day.

[Structure of the invention]

The first aspect of the present invention is a central shaft into which a female threaded cylinder is fitted;
It has a knob consisting of an intermediate wall that holds a spring between it and the center shaft, a skirt forming an outer periphery, a sleeve in the center into which the center shaft and spring are inserted, and a through hole that leads to the steam vent of the pot lid. A shallow dish-shaped stand is provided with a stopper projecting downwardly, and a sleeve into which the exposed part of the female threaded tube is fitted in the center,
A guide hole into which the stopper enters is provided transparently, and a fitting part is provided on the back side of the peripheral edge to fit into the blowing recess formed in the pot lid, and the center of the fitting part is connected to the steam hole of the pot lid. This is a pressure cooker lid knob comprising a guide plate with a communicating steam hole. are formed separately and fitted therein, and the drawings show examples of these. 1 to 4 relate to the first invention, in which the knob 1 is formed by forming a central shaft 2, an intermediate wall 3, and a skirt 4 in this order from the inside on a circular plate portion. The upper half of the female threaded cylinder 5 is fitted into the tip of the center shaft 2. Alternatively, it may be fitted over the entire length of the center shaft 2. A spring 7 for pressing down a stand 8, which will be described later, is inserted into the gap between the center shaft 2 and the intermediate wall 3. A recess 6 is formed on the upper surface of the knob 1 for fixing a nameplate. The stand 8 has a shallow dish shape, and a sleeve 9 for inserting the center shaft 2 of the knob 1 and the spring 7 is provided in the center of the stand 8.
A cone-shaped through hole 10 communicating with a steam hole 22 of a pot lid 21 is provided. Further, a stopper 11 that projects downward is provided on the back surface of the stand 8, and a gripping portion 12 of an appropriate shape is formed on the surface of the stopper 11 as necessary. The guide plate 13 is provided with a sleeve 14 in which the lower exposed portion of the female threaded tube 5 is fitted into its rotating shaft portion, and a guide hole 15 is provided in an arc shape at a position where the stopper 11 abuts. A circular fitting part 16 that fits into the blowing recess 23 formed on the pot lid 21 is provided on the rear side peripheral edge. Fitting part 1
A steam hole 17 is transparently provided in the center of 6. Although the illustrated guide plate 13 is fan-shaped, it goes without saying that it may also be disc-shaped. The pot lid 21 is provided with a shallow recess 24 for housing the stand 8 in addition to the blowing recess 23, and a male screw 25 is provided in the center of the pot lid 21.
erected. The female screw tube 5 of the knob 1 is screwed onto the male screw 25. FIG. 5 shows an embodiment of the second invention, in which the same reference numerals as in the first invention refer to the same constituent parts as in the first invention, so the explanation will be omitted. In the second invention, the blowing recess 23 is not provided in the pot lid 21, and that portion is simply a through hole 30. Further, the guide plate 13 is also not provided with the fitting part 16, but instead is provided with a deep-dish-shaped blowing valve 31, and its flange part 32 is placed on the peripheral edge of the through-hole 30. 30. A steam hole 33 is provided at the center of the blowing valve 31.

[Action of the invention]

To assemble the knob according to the invention, first the guide plate 13 is attached to the pot lid 21 by fitting its fitting part 16 into the blowing recess 23. Next, the stand 8 is placed over it. At this time, the stopper 11 is made to enter the guide hole 15. Finally, with the spring 7 wrapped around the center shaft 2, the knob 1 is fixed by screwing the female screw tube 5 onto the male screw 25. The stand 8 and the guide plate 13 are pressed down by the spring 7, so they do not wobble. Disassembly can be done in the reverse order of assembly, and in either case it can be done extremely easily, making it convenient for disassembly and cleaning. In the case of the second invention, the pot lid 2
After fitting the blowing valve 31 into the first through hole 30, it is assembled in substantially the same manner as the first invention.
When heating a pot for cooking, first, hold the grip part 12 and align the through hole 10 of the stand 8 with the steam hole 17 of the guide plate 13. That is,
When the gripping part 12 is moved laterally, the stand 8 freely rotates around the sleeve 14 of the guide plate 13, although within a range limited by the guide hole 15. If the stopper 11 is brought into contact with the end of the guide hole 15 at the position where the through hole 10 and the steam hole 17 match, the setting operation of the through hole 10 and the steam hole 17 can be performed extremely easily. Then it is heated and eventually boils,
Steam flows vigorously from the steam hole 22 to the blowing recess 23
The steam enters the interior and escapes through the steam hole 17 to the through hole 10, at which time it makes a loud noise to notify that it has boiled.
Therefore, when the stand 8 is rotated in the opposite direction by the grip 12, the through hole 10 comes off from the steam hole 17, and the steam hole 17 is closed by the back side of the stand 8, making the inside of the pot airtight. be done. At that point, add the ingredients or turn down the heat. The same applies to the second invention.

〔Effect of the invention〕

Since the present invention is as described above, boiling is notified by the sound of water vapor.
At that point, the steam vent can be blocked, ingredients can be added, and the heat can be turned down to low, allowing extremely efficient cooking.In addition, over-boiling is prevented, reducing fuel consumption.Furthermore, the structure is simple. This has the effect of making it easy to disassemble and clean.
