Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a pump-injection type liquid container, and more particularly, to a pump-injection type liquid container having a structure such that hot water can be stored in the liquid container. .

(Prior art) This type of pump injection type liquid container requires a steam vent structure to release the steam generated from the hot water stored in the liquid container into the outside air. In this type of general pump-filling type liquid container, the steam generated in the liquid container flows into the bellows pump from the pump discharge port and is discharged into the lid body from the pump suction port, and then the steam generated in the liquid container flows between the lid body and the pump. It was released into the outside air through the gap between the control panel and the control panel.

However, in this conventional pump injection type liquid container, the high temperature steam generated inside the liquid container comes into direct contact with the inner surface of the bellows pump before being released into the outside air, which increases the thermal effect on the thin film bellows pump. Therefore, there was a problem that the service life of the bellows pump was shortened.

In addition, in conventional pump-type liquid containers known as electric kettles, a large amount of high-temperature steam is ejected from a wide range of locations on the outer surface of the lid when boiling water, which causes heat to be applied to the components that the steam comes into contact with. Or, there is a risk of harmful effects such as moisture, etc.
There has been a problem in that even though the pump operating plate is heated to a high temperature by the high-temperature steam, the pump operating plate must be brought into contact with the relatively high temperature pump operating plate when operating the pump.

In addition, in pump-filling liquid containers in which the lid is hinged to the upper part of the liquid container body, the hinge-side lid is susceptible to large impact forces, especially when the liquid container falls over, but conventional In this type of pump-filling type liquid container, there is no special consideration given to reinforcing the hinge-side lid portion of the lid body, and there is a problem in that special reinforcement would complicate the structure.

(Purpose of the invention) In view of the above-mentioned problems with the conventional pump injection type liquid container, the present invention can prevent thermal effects on the bellows pump, and furthermore, the area in contact with high-temperature steam can be kept in a relatively narrow range. Moreover, by limiting the pouring operation to a place that cannot be touched when dispensing liquid,
A pump that can reduce the area that is adversely affected by heat and moisture, improve safety during pump operation, and has a simple structure that can be used effectively for other purposes. The object of the present invention is to provide a pouring type liquid container.

(Means for Achieving the Object) As a means for achieving the above object, the present invention provides a liquid container main body which houses a liquid container in an outer case, and an upper part of the liquid container main body which houses a bellows pump. a lid body pivoted by a hinge, an air suction passage formed between the bellows pump and the liquid container, and a series of liquid pouring passages for guiding the liquid in the liquid container to the outside. In the pump-filling liquid container, a divided first steam passage is provided on the lower surface of the lid, the inlet opening toward the air suction passage and the outlet extending toward the hinge side. A part of the first steam passage is formed by the bottom plate of the bellows pump, while an inlet side is connected to the outlet of the first steam passage at a hinge side end in the cover body, and an outlet is connected to the bottom plate of the bellows pump. It is characterized in that a second steam passage opened to the outside air from the upper surface of the body is integrally formed with the lid body.

(Function) According to the pump injection type liquid container of the present invention, the steam generated in the liquid container passes from the upper surface of the hinge side end of the lid through the divided first steam passage and second steam passage. It will be released into the outside air.

(Example) Figures 1 and 2 show the first embodiment of the present invention and the third embodiment of the present invention.
FIGS. 4A and 4B show pump-filled liquid containers of the second and third embodiments, respectively. Each of the pump injection type liquid containers of the first to third embodiments is constructed as a kettle type.

The pump injection type liquid container of the first embodiment shown in FIGS. 1 and 2 has a metal liquid container 5 having a wide opening housed in an outer case 4.

The lid unit 2 is pivotally attached to the upper rear side of the liquid container body 1 by a hinge 40.

A wide liquid supply port 7 is formed approximately in the center of the shoulder member 6. This liquid supply port 7 is connected to the liquid guide pipe unit 3.
It is opened and closed by an inner lid 19 that is integrally fixed to the lower surface of the intermediate member 16.

A water heater 41 is provided on the outer surface of the lower part of the liquid container 5.
and a heat-retaining heater 42 are wrapped around it.

The liquid pumping pipe 17 and the liquid pouring pipe 18 of the liquid guiding pipe unit 3 are connected to a liquid passage 26 formed in the intermediate member 16.

It constitutes a series of liquid pouring passages 8 that communicate the inside and outside of the chamber.

An air passage 27 is formed through the intermediate member 16 and the inner lid 19 in the vertical direction.

The lower surface of the bottom plate 10a of the bellows pump 10 is the lower surface of the lid 20 in this first embodiment. A relatively short annular wall 28 is formed on the lower surface of the bellows pump bottom plate 10a so as to surround the pump discharge port 32. An annular packing 39 is attached to the lower part of the annular wall 28, and when the lid is closed, the annular packing 39 comes into contact with the upper surface of the intermediate member 16 to establish airtight communication between the inside of the bellows pump 10 and the inside of the liquid container 5. It's starting to become easier.
In this first embodiment, the inside of the annular wall 28 and the air passage 27 in the intermediate member constitute a series of air blowing passages 9.

The lower surface of the lid body 20 (lower surface of the pump bottom plate) and the shoulder member 6
A first steam passage 12 having an inlet 12a opening into the air blowing passage 9 is formed between the first steam passage 12 and the upper surface of the first steam passage 12. This first steam passage 12 is connected to the pump bottom plate 10.
a and a gutter-like member 2 integrally formed with the annular wall 28
9, and the gutter-like member 29 is brought into airtight contact with the lower surface of the pump bottom plate 10a, thereby forming a partitioned passage. In this way, in forming the first steam passage 12,
When the pump bottom plate 10a is also used as a part of the first steam passage 12, the pump bottom plate 10a can be effectively utilized.

The inlet 12a side of the first steam passage 12 is opened obliquely downward in the annular wall 28, and the outlet 12b side of the first steam passage 12 is extended toward the hinge 40 side. ing.

At the end of the lid body 20 on the hinge 40 side, there is a cylindrical second steam passage 1 divided vertically.
3 are integrally formed. In this way, when the second steam passage 13 is integrally formed at the end of the lid body 20 on the side of the hinge 40, the second steam passage 13 can be formed without using a special member, and the structure can be simplified. This is simple, and the hinge side portion of the lid body 20 that is relatively susceptible to impact force can be reinforced without using any special structure, and the second steam passage 13 can be effectively used as a reinforcing material. The inlet 13a of the second steam passage 13 is opened downward, and the outlet 13b of the second steam passage 13 is opened upward to the outside air.

The outlet 12b of the first steam passage 12 faces upward into the inlet 13a of the second steam passage 13, and the first steam passage 12 and the second steam passage 13 connect the air blowing passage 9 to the outside of the liquid container. It constitutes a series of steam vent passages 11 that communicate with each other.

Inside the annular wall 28 is a valve member 21 that acts to selectively open and close the lower end opening of the pump discharge port 32, which serves as the valve port 22 communicating with the bellows pump 10 side, and the inlet 12a of the first steam passage 12. is installed. In this first embodiment, this valve member 21 includes a valve port side valve plate 23 that opens and closes the valve port (lower end opening of the pump discharge port) 22, and a first steam passage inlet side valve plate 2.
4 are integrally formed in a "F" shape, and the valve member 21 is pivotably connected to the lower surface of the pump bottom plate 10a by a pin 25 at the joint portion of each valve plate 23, 24. installed. In the natural state of this valve member 21, as shown in FIG.
4 is pivoted in a direction to open the first steam passage inlet 12a.

This valve member 21 is adapted to be operated in conjunction with the operation of the pump operation plate 30. That is, the valve member 21 is operated by a valve push rod 33 that passes through the pump discharge port 32 and reaches a considerable upper part within the bellows pump 10. This valve push rod 33 is connected to a pump suction port 31 provided on the pump top plate 10b.
It is designed to move up and down in conjunction with the up and down movement of a hook valve type suction valve 34 that opens and closes. The upper part of the valve push rod 33 is inserted into the cylindrical part 34a of the suction valve 34 so as to be able to slide vertically, and the upper part of the valve push rod 33 is urged downward by a push-down spring 35. . When the pump is stopped, as shown in FIG. 1, the suction valve 34 is in the upward position, and the valve push rod 33 is also moved upward, so that the lower end of the valve push rod 33 is positioned above the valve port 22. When the pump is operated, the suction valve 34 is moved downward as shown in FIG.
It is designed to act as if pushing down 3.
Therefore, when the pump is stopped (FIG. 1), the valve plate 23 on the valve port side of the valve member 21 closes the valve port 22, and at the same time, the valve plate 24 on the inlet side of the first steam passage closes the inlet 1 of the first steam passage.
2a, and when the pump is operated (Fig. 2), the valve port side valve plate 23 opens the valve port 22, and at the same time, the first steam passage inlet side valve plate 24 opens the first steam passage inlet 12a. It's becoming blocked.
Note that during pump operation, after the valve member 21 is rotated by the valve pusher rod 33 until the first steam passage inlet side valve plate 24 comes into contact with the first steam passage inlet 12a, the valve pusher rod 33 cannot be lowered any further. Only the suction valve 34 side can move downward.

In FIGS. 1 and 2, reference numeral 36 indicates a pump extension spring, and 37 indicates a ring gasket for keeping the space between the outlet 12b of the first steam passage 12 and the inlet 13a of the second steam passage 13 airtight. It shows.

Next, to explain the operation of the pump injection type liquid container of the first embodiment shown in FIGS. 1 and 2, a large amount of high-temperature steam is generated from the liquid in the liquid container 5 when boiling water, but when the pump is stopped, The steam passes through the air blowing passage 9 (the air passage 27 in the intermediate member and the inside of the annular wall 28) and the series of steam vent passages 11 (the first steam passage 12 and the second steam passage 13) to the lid body 20.
It is released into the outside air from the steam outlet (second steam passage outlet 13b) on the rear side (opposite the spout side). Note that when the pump is at rest, the valve port 22 that communicates with the inside of the bellows pump 10 is closed by the valve port side valve plate 23 of the valve member 21, so steam does not enter the bellows pump 10 side, and the Since the steam vent passage 11 is divided, the steam is not released into the gap between the liquid container main body 1 and the lid unit 2, and is concentrated and released into the outside air from the steam outlet on the rear side of the lid 20. be done. When dispensing liquid, when the pump operation plate 30 is pressed, the valve member 21 pivots as shown in FIG.
Pressurized air from the bellows pump 10 is blown into the liquid container 5 through a series of air blowing passages 9, and the pressurized air blows the liquid in the liquid container 5 into a series of The liquid can be poured out through the liquid pouring passage 8 to the outside.

In the pump injection type liquid container of the second embodiment shown in FIG. The valve port 22 at the lower end of the pump discharge port 32 and the first steam passage inlet 12
It is installed so that it can move up and down between a. Further, the valve member 21 is urged upward by the push-up spring 45 to close the valve port 22 and open the first steam passage inlet 12a, and is pushed against the push-up spring 45 by the valve push rod 33 during pump operation. The valve opening 22 is moved downward to close the first steam passage inlet 12a and open the valve port 22.

The pump injection type liquid container of the third embodiment shown in FIG. 4 is a modification of the pump injection type liquid container of the second embodiment shown in FIG. In the pump liquid container of the third embodiment, the valve member 21 for selectively opening and closing the valve port (lower end opening of the pump discharge port) 22 and the inlet 12a of the first steam passage 12 is operated by the pump operation. The valve push rod 33 is integrally formed at the lower end of the valve push rod 33, which moves up and down in conjunction with the valve pusher 33. When the pump is stopped, the valve member 21 closes the valve port 22 and opens the first steam passage inlet 12a, and when the pump is operated, the valve push rod 33 is moved downward, and the valve member 21 at the lower end thereof is moved downward.
1 directly closes the first steam passage inlet 12a and opens the valve port 22.

(Effects of the invention) The pump injection type liquid container of the invention has the following effects.

(1) Since the steam generated in the liquid container 5 is released into the outside air through the first steam passage 12 and the second steam passage 13, the bellows pump 10 can be protected from high-temperature steam.

(2) High-temperature steam generated in the liquid container 5 is collected and released into the outside air through the divided first steam passage 12 and the second steam passage 13 formed at the end opposite to the spout of the lid body 20. Therefore, compared to a conventional pump-filling type liquid container of this type in which steam is diffused and released into the surroundings, the area that is adversely affected by high-temperature steam can be made smaller.

(3) Since the outlet 13b of the second steam passage 13 is opened to the outside air from the upper surface of the end on the side opposite to the spout of the lid body 20, the high-temperature steam generated in the liquid container 5 can be discharged to the outside air. Since it is far away from the spout 18a, the steam released during the liquid pouring operation is difficult to touch, improving safety.

(4) Since the first steam passage 12 is partially formed using the bottom plate 10a of the bellows pump 10, the pump bottom plate 10a can be effectively used as a member for forming the first steam passage 12.

(5) Since the second steam passage 13 is integrally formed with the lid 20 at the hinge side end within the lid 20, even if the steam passage 13 is provided inside the lid 2, There is no need to use special members, the structure is simple, and the lid body 20
The portion on the hinge 40 side, which is relatively susceptible to impact force, can be reinforced with the second steam passage 13 without using any special structure, and the second steam passage 13 can be effectively used as a reinforcing member.
