Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an electric air pressurized liquid container that allows the liquid inside to be poured out to the outside using pressurized air from an electric air pressurization pump. It is something.

(Prior art) In a pump injection type liquid container, it is necessary to form a steam vent passage to release the vapor generated from the liquid in the liquid container into the outside air. In this type of liquid container, the vapor is temporarily released into a space inside the lid and then released from around the lid to the outside. However, when steam is released into the lid in this way,
In addition to the problem of the steam having an adverse effect on other components placed inside the lid, the steam outlet is not specified, and a large amount of high-temperature steam is generated when heating, especially in the case of a kettle type, which poses a risk of burns. There was also the issue of gender.

In addition, some of the known electric air pressurized liquid containers include:
A structure as shown in FIG. 8 is known (Japanese Utility Model Application Publication No. 56-32621). This known electric air pressurized liquid container supplies pressurized air from an electric air pressurizing pump (not shown) provided at the bottom of the container body 101 through a blow pipe 118, a connecting pipe 119, and an air passage 120 in the stopper. The air can be blown into the liquid container 104 through a series of air blowing passages 117. The connecting pipe 119 is a ventilation passage 120
When the operation button 124 is pressed (liquid dispensing operation), the connecting pipe 119 connects to the air passage 120 inside the stopper and pressurizes the air with electric power. It becomes possible to introduce pressurized air from the pump into the liquid container 104, and when the operation button 124 is not operated (when the pump is stopped), the connecting pipe 119 is separated from the air passage 120 in the stopper, and the liquid is Steam generated within the container 104 is released from the upper end opening of the in-stopper air passage 120 into the space S between the container body 101 and the lid body 102, and then released to the outside. However, in the electric air pressurized liquid container of this known example, when the pump is inactive (when the operation button 124 is not operated), the steam generated in the liquid container 104 passes through the in-stop ventilation passage 120 and enters the container body from the upper end opening. After being discharged into the space S between the top surface of the container body 101 and the top surface of the lid body 102, it is discharged to the outside from the wide outer circumferential portion between the container body 101 and the lid body 102, and the high temperature is There is a risk of burns from the steam,
Further, a series of air blowing passages 117 are connected to the upper end 118a of the blower pipe 118, the base end 119a of the connecting pipe 119, the distal end 119b of the connecting pipe 119, and the in-plug air passage 12.
0 and the upper end 120a of 0, there is a risk of air leakage from those joints due to damage to the gaskets 121 and 122 during long-term use, for example. There is a problem that sometimes the pressure necessary to pump the liquid into the liquid container 104 cannot be obtained.

(Purpose of the invention) In view of the above-mentioned conventional problems, the present invention is designed to prevent the steam generated inside the liquid container from leaking into the lid and to release it only from a small specified area outside the lid. Another object of the present invention is to provide an electric air pressurized liquid container that prevents pressurized air from an electric air pressurizing pump from leaking to the outside when the pump is operated.

(Means for achieving the object) The present invention blows pressurized air from an electric air pressurizing pump into a liquid container housed inside a container body through an air blowing passage, and uses the pressurized air to blow liquid into a liquid container. In an electric air pressurized liquid container in which the liquid in the container can be poured out to the outside through a series of pouring passages, a steam venting passage for discharging the steam generated in the liquid container to the outside is connected to the air blowing passage. Separately from the passage, the passage passes through the lid body covering the upper part of the container body, and is separated from the constituent members of the lid body from inside the liquid container to the outside of the lid body, and is formed in the middle of the steam vent passage. A valve body made of an elastic body that opens and closes the steam vent passage is airtightly provided with respect to the steam vent passage, and the valve body has an operating portion facing outside the steam vent passage and a valve portion facing inside the steam vent passage. It is characterized in that the valve body is operated from the outside to close the steam vent passage.

(Function) The electric air pressurized liquid container of the present invention has a vapor release passage divided from the liquid container to the outside of the lid, so that the steam generated inside the liquid container can be removed from the container body or inside the lid. Moreover, since the steam venting passage is formed separately from the air blowing passage, the steam venting passage and the air blowing passage are separated from each other. This makes it easier to ensure the airtightness of the air-tightness of the steam vent passage, and since the valve body is provided in the middle of the steam vent passage and can be forcibly closed by the operating member, the valve body can be securely closed when the pump is operated. It becomes possible to block it. In addition, since the valve body is made of an elastic material, it has good airtightness when the valve is closed.
Further, since the valve body is provided airtightly with respect to the steam vent passage, the steam vent passage can be completely closed off from the lid body.

The bottom of the liquid container 4 is suspended from the outer case 3.
It is connected via a support 7 to a bottom member 6 that is in contact with the lower edge.

An electric heater 8 is provided around the lower side of the liquid container 4, and the electric heater 8 is configured to heat and keep warm the liquid contained in the liquid container 4.

The front surface of the outer case 3 has a pouring passage 1 which will be described later.
It is covered with a front cover 9 for attaching an elevating pipe 14 for assisting pouring, which is a part of the 0.

An electric air pressurizing pump 15 for pumping pressurized air into the liquid container 4 is installed inside the lower part of the front cover 9 . In addition, the electric air pressurizing pump 1
5 is installed at a lower position than the liquid container 4, and a heat shield plate 16 is interposed around its outer periphery to block heat from the electric heater 8.

The pressurized air fed from the electric air pressure pump 15 is discharged from a discharge port 18 opened at the upper part of the side circumference of the liquid container 4 via a pump 17 (which serves as an air blowing passage). , in this embodiment, the upper end opening 4a of the liquid container 4 is located in the middle of the pump 17.
The higher portion 17a is formed to prevent liquid from flowing back toward the electric air pressure pump 15 side. Reference numeral 19 denotes a locking tool fixed to the inner surface of the outer case 3 to support the high portion 17a.

A micro switch 20 that acts as a switch to control energization to the electric air pressurizing pump 15
is fixed to the lower front surface of the lower opening member 5. As shown in FIG.
It has a waterproof mounting structure in which it is screwed to the lower opening member 5 with a sealing member 22 interposed between it and the lower surface, and is operated by an actuator 23 that moves up and down integrally with the sealing member 22. It is designed to be opened and closed. The actuator 23 passes through the lower mouth member 5 and projects upward, and faces an operating member 24, which will be described later.

The upper end opening 4a of the liquid container 4 is covered with an inner lid 25, and the inner lid 25 includes a top opening 4a of the liquid container 4.
A ventilation passage 27, which is a part of the steam vent passage 26, and a water passage 28, which is a part of the pouring passage 10, are provided together to prevent natural pressure increase within the tank or to release a large amount of steam generated during heating. Naru passage unit 2
9 is provided. The water passage 28 communicates with the pumping pipe 11 and the pouring pipe 12 which extend downward and forward from the passage unit 29, respectively. The pouring pipe 12 and the elevating pipe 14 are connected via a connecting pipe 13. That is, the pouring passage 10 is constituted by the pumping pipe 11, the water passage 28, the pouring pipe 12, the connecting pipe 13, and the elevator pipe 14.

There is a liquid container 4 between the inside of the liquid container 4 and the outer surface of the lid body 2.
A steam vent passage 26 is formed for releasing steam generated inside to the outside. This steam venting passage 26 is provided independently of the air blowing passage (pipe) 17. Also, this steam vent passage 26
is composed of the air passage 27 of the passage unit 29 and a tubular passage member 30 provided on the lid 2 side. When the lid is closed, the steam vent passage 26 is partitioned from the container body 1 or the lid 2, with the ventilation passage 27 and the passage member 30 being in airtight communication with each other via the seal packing 33. It is now composed of

The exhaust port 31 of the steam venting passage 26 is opened upward at the rear of the upper surface of the lid body 2. This discharge port 31 is provided with a cap 32 having a gas-liquid separation function. A valve body 34 for opening and closing the steam vent passage 26 is provided in the middle of the passage member 30 on the lid body 2 side. This valve body 34 is
The valve body 34 is made of an elastic body such as rubber or soft synthetic resin, and an elastic disc 34a is integrally formed on the outside of the valve body 34. The valve body 34 has its operating portion 34b placed outside the steam vent passage 26 and its valve portion 34c.
The outer peripheral edge of the elastic disc 34a faces the steam vent passage 26, and
It is airtightly attached to the steam vent passage 26 by force-fitting it to the edge of the valve body installation opening 30B. Further, in this valve body 34, the valve portion 34c is normally connected to the passage member 3 due to the elasticity of the elastic disc 34a.
The valve seat 30A is installed so as to be spaced apart above the valve seat 30A provided in the valve seat 30A. Since the valve body 34 is formed of an elastic body in this way, it comes into elastic contact with the valve seat 30A when the valve is closed, and has the effect of being able to seal the valve seat well and absorbing dimensional manipulation. be. The elastic disc 34a seals the rim of the valve body installation opening 30B provided in the passage member 30, thereby completely separating the steam vent passage 26 (passage member 30) from inside the lid body 2. are doing. Therefore, steam passing through the steam vent passage 26 can be completely prevented from leaking into the lid 2.

The valve body 34 is forcibly operated by a passage closing member 35 operated by the operating member 24.

In this embodiment, the passage closing member 35 has one end 35.
It consists of a lever-shaped member that is rotatably supported at the rear inside the lid body 2. The other end 35b of the passage closing member 35 is interlocked with an operating member 24 disposed at the front end of the lid 2, which also functions as a switch operation. Further, a protrusion 35c that presses the valve body 34 is provided in a protruding manner at the intermediate portion of the passage closing member 35. When the operation member 24 is pressed, the protrusion 35c of the passage closing member 35 can press the operation portion (upper surface of the valve body) 34b of the valve body 34 to close the valve.

The operating member 24 passes through the lid 2 in the vertical direction and is opposed to the actuator 23 of the micro switch 20.
It faces on the top surface at a position separated from the outlet 31 of the air passage 26. In this way, the operator can manually operate the operating section 24a without feeling a sense of danger.

In the drawing, reference numeral 36 is a heat insulating material, 37 is a lock lever that locks the operating member 24 when not in use, 38 is a spring for returning the operating member 24, and 39 is a power outlet.

The illustrated liquid container operates as follows.

When a liquid, for example water, is stored in the liquid container 4 and the power outlet 39 is inserted, the water in the liquid container 4 is heated by the electric heater 8 and then kept at a constant temperature (approximately 90℃).
℃).

When pouring hot water, after releasing the lock by the lock lever 37, the operating member 24
Press down manually. Then, the microswitch 20 is closed by the operating member 24, and at the same time, the valve body 34 is forcibly closed by the passage closing member 35. Therefore, the electric air pressurizing pump 15 is driven to blow pressurized air into the liquid container 4 through the air blowing passage (pipe) 17, and the pressurized air causes hot water in the liquid container 4 to flow into the pouring passage. It is pushed out through 10.

Thereafter, when the pressing force on the operating member 24 is released, the micro switch 20 is opened and the valve body 34 is also opened, and the electric air pressurizing pump 15 is stopped to complete the pouring.

Steam generated from the liquid in the liquid container 4 passes through a series of steam vent passages 26 and is released into the outside air from its outlet 31. Since the liquid container 4 is partitioned, the steam generated in the liquid container 4 will not leak into the container body 1 or the lid 2. Further, since the steam vent passage 26 is provided independently of the air blowing passage 17, the airtightness of each passage (the steam vent passage 26 and the air blowing passage 17) can be easily ensured. Furthermore, since the valve body 34 is forcibly closed when the operating member 24 is operated, the steam vent passage 26 is reliably closed when the pump is operated (when the operating member 24 is operated). Air leakage does not occur from the steam vent passage 26.

The front and back are opposite to those of the example. Other configurations and operations are similar to those of the first embodiment.

FIG. 4 shows a third embodiment of the present invention, in which the passage closing member 35 is shaped like a push button and is configured to be operated separately from the operating member 24. Therefore, when injecting liquid, the operation member 24
and passage closing member 35 must be operated. This improves safety against malfunctions. Reference numeral 40 denotes a spring for returning the passage closing member 35. Other configurations and operations are similar to those of the second embodiment.

FIG. 5 shows a fourth embodiment of the present invention, in which a reed switch 20 fixed to the rear lower surface of the lower opening member 5 is used instead of the micro switch 20.
has been adopted. In addition, a button-shaped passage closing member 35
The operating member 24 is constructed by fixing a magnet 41 to the tip of a lever member integrally extending rearward from the lever member. The operating portion 24a of the operating member 24 is placed facing the center of the top surface of the lid 2 so as to also serve as the operating portion of the passage closing member 35. Then, when the operating portion 24a is pressed, the valve body 34 is operated to close, and at the same time, the reed switch 20 is closed by the approach of the magnet 41. Other configurations and operations are similar to those of the third embodiment.

FIG. 6 shows a fifth embodiment of the present invention, in which an operating member 24 and a passage closing member 35 are shown.
is composed of the same operating member A. The reed switch 2 disposed on the side of the actuating member A is controlled by the magnet 41 fixed to the actuating member A side.
0 is closed. Other configurations and operations are similar to those of the fourth embodiment.

FIG. 7 shows a sixth embodiment of the present invention, in which, unlike the fifth embodiment, a reed switch 20 is disposed within the actuating member A, and a magnet 4
1 is arranged on the outer peripheral side of the actuating member A. Other configurations and operations are similar to those of the fifth embodiment.

(Effects of the invention) The electric air pressurized liquid container of the invention has the following effects.

(1) Since the steam venting passage 26 is separated from the components of the lid body from inside the liquid container 4 to the outside of the lid body, the steam generated inside the liquid container 4 is separated from the inside of the liquid container (liquid This prevents the vapor from leaking outside the container 4, and prevents the vapor from having an adverse effect on other members within the liquid container.

(2) Since the steam generated in the liquid container 4 is released only from a specific location outside the lid 2 (the exit of the steam vent passage 26), the risk of burns and the like due to high-temperature steam is reduced.

(3) Since the steam vent passage 26 is provided independently of the air blowing passage 17, the airtightness of each of these passages can be improved. Furthermore, the 8th
If a part of the air blowing passage is also used as a steam venting passage as in the known example shown in the figure, a connecting part that can be freely connected and separated is required, and air leakage is likely to occur there.

(4) Since the valve body 34 that opens and closes the steam vent passage 26 is made of an elastic body, it comes into elastic contact with the valve seat 30A when the valve is closed, and the valve seat is sealed well. It can be absorbed by the body 34.

(5) Since the valve body 34 is provided airtightly with respect to the steam vent passage 26, it is possible to reliably prevent steam passing through the steam vent passage 26 from leaking into the lid body 2.
