Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a pot used for boiling water and keeping the water warm.

[Technical background of the invention and its problems]

In this type of pot, a bottomed cylindrical tank is housed in a bottomed cylindrical case, and the water is heated and kept warm through this tank. The case has a support ring at the upper opening edge, and the tank is inserted into the case through the inner opening of the support ring. This tank has a flange integrally formed on the edge of the upper opening, and this flange abuts against the periphery of the inner opening of the support ring, and this abutment supports the tank in a suspended manner. A screw is inserted from the outer bottom surface of the tank into a mounting piece on the bottom surface of the tank, and the tank is fixed by tightening this screw.

However, when the tank is inserted into the case, the tank is in an unstable suspended state where the flange simply butts against the support ring as described above, so the screws must be inserted from the outer bottom of the case. When fixing the tank, the tank will swing around unnecessarily, making it difficult to perform the work. Also, when performing maintenance and inspection after assembly, if the case is turned upside down and the mounting screws on the outer bottom are removed and disassembled, the tank may be unprepared. There was a risk that it would fall below the case and cause damage.

[Purpose of invention]

The present invention was developed with these points in mind, and its purpose is to make it possible to easily and efficiently fix the tank, and to prevent the tank from accidentally falling during disassembly. The aim is to provide pots that are

[Summary of the idea]

The present invention is characterized in that a fastening device is provided for fastening the tank to the support ring.

4 is elastically urged upward by the spring 32. A tapered valve seat 34 is formed at the inner peripheral edge of the upper end of the opening 30, and
Further, a packing 35 is provided on the bellows valve 31 so as to face the valve seat 34 thereof. Under normal conditions, the inside of the bellows 24 communicates with the atmosphere through a cutout window 37 on the circumferential surface of the bellows valve 31.
When the packing 35 comes into contact with the valve seat 34, the opening 30 is sealed and communication with the atmosphere is cut off. A reinforcing plate 36 is provided on the upper surface of the bellows 24, and this reinforcing plate 36 is formed to have a size that is approximately the same as or larger than the outer diameter of the bellows 24, and is located on the outer periphery of the opening 30. It is fitted and integrally attached to the bellows 24.

A push body 40 is housed in the recess 22 of the upper lid 20 so as to be movable up and down, and a press cylinder 41 is slidably inserted upward from the center of the bottom of the recess 22, and the upper end of the press cylinder 41 is screwed. Push body 40 via 42
is connected to. The pressing cylinder 41 integrally has a flange 43 at its lower end, and this flange 43 abuts against the upper surface of the bellows valve 31, and a guide cylinder 44 integrally protrudes from the center of the upper surface of the bellows valve 31. 44 is slidably fitted into the inner periphery of the press cylinder 41.

An outflow pipe 50 is attached to one side of the bottom of the tank 7 by crimping or the like, and the upper end of this outflow pipe 50 projects slightly above the inner bottom surface of the tank 7. The support ring 5 has a guide path 5 that is approximately in the shape of an inverted U.
1 is formed, and a check valve 5 is provided at one end of this guide path 51.
A conduction pipe 53 is connected via 2. Joints 54 and 55 made of rubber, for example, are attached to the lower end of the conduit pipe 53 and the lower end of the outflow pipe 50, respectively. Both the joints 54 and 55 are connected to each other via a connecting tube 56, and a protrusion 57 that continues along the circumferential direction is integrally formed at the intermediate portion of the outer periphery of the connecting tube 56. An outflow pipe 58 is formed at the other end of the guide path 51, and a lead-out pipe 59 is fitted on the outer periphery of the outflow pipe 58. It serves as an outlet port 60. A spouting pipe 64 overlaps the outer periphery of the outlet pipe 59, and this spouting pipe 64 is supported via a decorative plate 65 attached to the front surface of the case 1 so as to be freely movable up and down. The outer periphery of the spouting pipe 64 is connected to this spouting pipe 64 and the screw 6.
A spout 68 at the tip of the spout tube 64 protrudes from the lower end surface of the cover 67 .

A heater 69 is wound around the outer peripheral surface of the lower end of the tank 7, and the liquid in the tank 7 is heated by the heater 69, and its temperature is maintained constant via a thermostat 70. Also 7
1 is a plug receiver, 72 is a handle, and 73 is a locking mechanism for the top cover 20.

When the pushing body 40 is pressed, the pressing cylinder 41 and the bellows valve 31 are lowered together with the pushing body 40. As the bellows valve 31 descends, the packing 35 collides with the catch seat 34, and the bellows 2
4 is sealed, and in this state, the bellows 24 is pressed through the bellows valve 31 to compress the air inside, and this compressed air flows into the tank 7 through the air introduction path 16. This inflow pressurizes the liquid level in the tank 7, and this pressurization causes the liquid to flow from the outflow pipe 50 to the conduit pipe 5.
3 and is pushed upward through the outlet pipe 59 and is led out from the outlet 60 and further passes through the outlet pipe 64 and is poured out from the outlet 68.

When the pressure of the push body 40 is released, the spring 3
2, the bellows valve 31 rises and the packing 35 separates from the seat 34. In response, air flows into the bellows 24 from the outside through the opening 30, and with this inflow, the bellows 24 becomes compressed. At the same time, the pushing body 4 is restored to the extended state from
0, the pressing cylinder 41 and the bellows valve 31 return to their original positions. By repeating such operations, the liquid in the tank 7 is sequentially poured out.

To explain the procedure for assembling the tank 7, first arrange the packing 9 on the stepped portion 6a of the support ring 5,
Next, insert the tank 7 into the opening 6 and attach the flange 8.
is brought into contact with the packing 9. The tank 7 is elastically pressed by the respective fasteners 11... and the support ring 5
After that, the tank 7 is inserted into the case 1, and the support ring 5 is press-fitted into the upper opening of the case 1. Then, the mounting screws 10, 10 are inserted from the outer bottom surface of the case 1, screwed into the mounting piece 7a of the tank 7, and tightened.
This completes the installation of the tank 7 and its fixing work.

The tank 7 is fixed to the support ring 5 via the fasteners 11, so that the tank 7 does not swing as in the conventional case. The work of fixing the tank 7 by screwing it into 7a can be done easily and efficiently.
Furthermore, even when the case 1 is turned upside down and the mounting screws 10, 10 are removed during maintenance and inspection, the tank 7 is integrally attached to the support ring 5.
The tank 7 will not fall below the case 1.

In the above embodiment, the anchoring device 11 is attached to the support ring 5 in advance, but this is done after the tank 7 is inserted into the opening 6 of the support ring 5, as shown in FIG. The dowel 7b may be press-fitted between the inner circumferential surface of the opening 6 and the outer circumferential surface of the tank 7.
is formed in advance, and this dowel 7b is used to secure the fastening tool 11.
By locking one end edge of the locking tool 11, it is possible to prevent the locking tool 11 from accidentally falling off. Furthermore, the fastening tool 11 is not limited to the case where it is formed of an elastic plate material in an inverted V shape, but it can also be formed into a wedge shape as shown in FIG. It may be press-fitted between the inner peripheral surface of tank 6 and the outer peripheral surface of tank 7. Furthermore, as shown in FIG. 6, the fastening tool 11 is formed into a band shape, and the fastening tool 11 is attached to the outer periphery of the tank 7 after insertion, and is brought into contact with the lower end surface of the support ring 5. In this state, both ends of the fastening tool 11 may be fastened together via the screws 11a, and the tank 7 may be fastened to the support ring 5 using the fastening tool 11.
