Description

[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application) This invention boils hot water in a container equipped with a heater.
This invention relates to an electric kettle in which the hot water flows out from a pouring spout using compressed air using a bellows.

(Prior Art) Conventionally, as a device of this kind, Japanese Utility Model Application Publication No. 101930/1983 discloses a container built into a case for storing water,
A lid provided on the top of the case, a heater that heats the container, a boiling control sensor that detects the steam temperature, and a power control device that controls the output of the heater based on the output of this sensor. An electric pot is disclosed in which a water level gauge is provided at the top of the pot, and the boiling control sensor is disposed at the upper end attachment part of the water level gauge located above the water level line so as to face the inside of the container. Further, in Japanese Utility Model Application Publication No. 57-54337, a case equipped with a handle is provided with a container equipped with a heater, a lid removably provided on the upper part of the case is provided with a steam escape path having a horizontal portion, and the above-mentioned An electric pot is disclosed in which a boiling control sensor is provided in the horizontal part. Furthermore, JP-A-58-
No. 159715 and Japanese Unexamined Patent Publication No. 58-67220 disclose an electric pot equipped with a switching device that responds to the bellows to selectively shut off the steam relief path and the compressed air supply path; A steam release path is provided, which rises up at an angle from a horizontal part where one end is open in the stopper lid, extends from the rising part to the outside of the exterior case, and bends the other side downward to serve as a release port. A boiling type electric hot water storage device has been proposed in which a sensor is attached to an outer case facing the outlet of a steam release path.

(Problem to be solved by the invention) In the above-mentioned electric pot with a boiling control sensor protruding from the water level gauge, air also stagnates at the top of the water level gauge, making it difficult for steam to reach the boiling control sensor. There is a risk that a response delay in steam detection may occur or a malfunction may occur. Furthermore, in electric pots with a boil control sensor installed in the lid, the boil control sensor is installed in the horizontal part of the steam release path, but condensed water accumulates in the horizontal part and blocks the discharge path. As a result, steam will no longer reach the boiling control sensor, leading to concerns about a delayed response in steam detection. In the electric pot that switches between the steam escape path and the compressed air supply path,
Since the steam exhaust hole is provided near the pouring spout or the pushing body, there is a risk that the steam may come into contact with the hand when the cup is held below the pouring spout and the pushing body is operated. Furthermore, in a boiling type electric hot water storage device in which a sensor is attached to the exterior case facing the outlet of the steam release path, the steam release path becomes labyrinth-like and obstructs the flow of steam, and the horizontal part of the steam release path Since this is a horizontal recess, condensed water accumulates in that area and blocks the steam exhaust path, making it difficult for steam to reach the sensor.Also, since the sensor is directly exposed to the outside, it is not exposed to the outside air. influenced,
Similar to the case described above, a delay in response or malfunction of vapor detection by the sensor occurs.

The object of the present invention is to solve the above-mentioned problems and to provide an electric pot which is free from delayed response in steam detection and from the possibility of malfunction, and which is excellent in safety.

A plurality of steam exhaust holes 31 are bored in the vicinity of the hinge pins 13 of the substrate 14, passing through the wall surface of the upper lid 12 and communicating with the steam escape passage 8. Protrusions 32 and 33 are formed on the other end sides of the end plate 2 and the upper lid 12, respectively, and these protrusions 32 and 33 overlap each other so as to be able to approach and separate, and the end plate 2
The bottom of the container 3 and the pouring spout 34 are located inside the protrusion 32 of the container 3.
A hot water guide portion 36 of a hot water supply path 35 is formed between the two.
This molten metal guide part 36 is opened to the outside through a pouring port 34 formed on the lower surface of the tip side of the protruding part 32, and is connected to the bottom of the container 3 via a check valve 37 at the proximal end of this molten metal guide part 36. A rising passageway 38 communicating with is connected thereto. 39 is a locking mechanism for locking the top cover 12 to the end plate 2, and a claw body 40a interlocks with the lever 40.

According to such a configuration, the boiling control sensor 53 detects steam and controls the heater 7,
In addition, the steam generated in the container 3 is passed through an inlet 9, an obliquely upward steam escape passage 8, an outlet 10, and a steam exhaust hole 31.
This prevents the inside of the container 3 from becoming abnormally high in pressure, and when the pushing body 18 is pressed downward, the first spring 28 is compressed.
Due to this compression, the opening/closing body 24 moves downward, and the opening/closing plate 25a collides with the inlet 9 side via the packing 25, thereby blocking the inlet 9 side and connecting the compressed air supply path 27 and the exhaust hole 27a. Communication is opened via the flow path 11 in response to the operation of the bellows 16. Further, as the pushing body 18 is lowered, the closing part 22 of the closing body 20 is pushed into the packing 23a of the through hole 23.
, the inside of the bellows 16 is sealed, and the movable plate 15 is pressed downward, thereby compressing the bellows 16 and the air inside it. Then, the compressed air is supplied to the compressed air supply path 27,
The hot water is fed into the container 3 through the flow path 11 and the exhaust hole 27a, and the liquid level of the hot water is pressurized. Due to this pressurization, a part of the hot water in the container 3 is transferred to the riser passage 38 and the hot water introduction part 3.
6 and is led out from the spout 34. After that, when the pressing force of the pushing body 18 is released, the pressing force 18 rises due to the elastic force of the second spring 29, and accordingly, the opening/closing body 24 rises due to the elastic force of the second spring 29, and the closing body 22 moves to the packing 23a. External air flows into the bellows 16 through the through hole 23. At the same time, the movable plate 15 rises and the bellows 16 is restored to its original state. By repeating such operations, the hot water in the container 3 can be taken out in appropriate amounts. and container 3
The inside communicates with the outside through the steam escape passage 8, but when the bellows 16 causes a compression operation, the steam escape passage 8 is closed by the opening/closing plate 25a of the switching device 26 and the packing 25, and the inside of the container 3 and the outside are closed. Since the communication state with the bellows 16 is cut off, the compressed air in the bellows 16 can be reliably introduced into the container 3 without leaking to the outside. Under normal conditions, the steam in the container 3 does not pass through the bellows 16.
It is discharged to the outside through a separate steam escape passage 8.

More specifically, a bottom plate metal fitting 44 is attached to the outside of the bottom surface of the container 3 by spot welding or the like. A leg stopper 45 is attached to this bottom plate metal fitting 44, and a leg 46 whose upper part is inserted and fixed inside the outer peripheral part of the end plate 2 and is provided on the lower edge of the case body 1a surrounding the side of the container 3; The leg stopper 45 is pulled downward and fixed by the bottom plate set screw 48 via the bottom plate 47. This tensile force causes the container 3 to
It is also stretched and fixed. By attaching it in this manner, the inner stopper packing 5 is pressed against the end plate 2 and the upper edge of the container 3, and the gap created between the end plate 2 and the container 3 is sealed.

By providing a switching device 26 that selectively blocks off the compressed air supply path 27 from the flow path 11 side, the compressed air supply path 27 is normally shut off and steam is passed to the steam release path 8 for boiling control. The sensor 53 can detect steam, and there is no possibility that steam will enter the inside of the bellows 16, thereby preventing deterioration of the bellows 16. In particular, if a part of the steam escape path 8, a communication path between the inside of the bellows 16 and the inside of the container 3, and the internal parts of the bellows 16 are protected with fluororubber, deterioration due to high temperature and high humidity steam can be prevented, resulting in excellent durability.

It has excellent boiling sensitivity. The wall surface of the steam escape passage 8 is made of stainless steel, and the outer periphery thereof is wrapped with a steam pipe cover 59 which is a molded product, thereby eliminating the possibility that hands may come into direct contact with the steam pipe 58 and cause burns or the like. The stainless steel wall surface of the steam pipe 58 is formed by joining the divided wall surfaces 58a and 58b, and by enclosing the divided wall surfaces 59a and 59b of a molded product such as plastic on the outer periphery. It can be manufactured at low cost. By forming the steam escape passage 8 with fluoro rubber other than stainless steel at the parts exposed to steam, such as the packing, deterioration due to high temperature and high humidity caused by steam can be prevented and durability can be increased.
The steam escape path 8 of the inner plug 6 is a bellows 1 that covers the inner plug 6.

Outlet 10 of steam escape passage 8
By closing the upper lid 12 and communicating with the steam exhaust hole 31 of the upper lid 12 which communicates with the outlet 10, the exhaust of steam can be visualized and can be exhausted smoothly. Furthermore, since the boiling control sensor 53 has a removable sensor mounting bracket 61 that forms a part of the case 1, the boiling control sensor 53 can be easily removed and installed, and maintenance work can be performed easily. Since the part of the hot water supply path 35 near the pouring spout 34 is vertical, if a cup or the like is placed directly below the pouring spout 34, the hot water can be reliably poured. Since the hot water supply path 35 near the pouring port 34 is removable, it can be removed and cleaned, which is sanitary. Since the micro switch 81 for the boiling operation of the heaters 7 and 7a is located above the water level gauge 41 attached to the case 1, the water level gauge 41 is checked at the same time as the micro switch 81 is operated, thereby preventing dry firing. can. By attaching the micro switch 81 for boiling operation to the attachment part integrated with the decorative name plate member 78, the switch button 83 itself also becomes an accessory, resulting in an excellent aesthetic appearance. The water level gauge 41 and the water level gauge cover 42 are inserted into the case 1 at the insertion part 42a, and the upper end of the water level gauge cover 42 is inserted into a part of the decorative nameplate 78, and the lower end is inserted into the leg part 46 of the case 1. Since the water level gauge cover 42 is held down and fixed, the water level gauge cover 42 can be easily attached. Packing 25, which is the lower part of the bellows 16, opening/closing plate 2

Furthermore, since the steam exhaust hole is provided near the hinge, when a cup or the like is brought close to the spout for pouring hot water and the pusher is operated, the steam does not come into contact with the hand, resulting in excellent safety. In addition, since the steam relief passage is formed with an upward slope, there is no chance of condensed water accumulating and blocking the steam relief passage, and the steam reliably reaches the boiling control sensor, allowing steam detection. This can prevent delays in response.
