Description

[Detailed description of the invention] The present invention relates to a flat electric pot equipped with a pump for pushing out the liquid content through the injection pipe, with a liquid injection pipe erected from inside the flat insulation container equipped with a heater. .

This type of flat electric pot has been developed in the past.
This is known from the publication No. 50332. In this device, a liquid injection pipe is provided upright at the rear of a flat heat-retaining container, and a pump is provided above and behind the liquid injection pipe.

This product has the advantage of increasing the heating efficiency of the heater by adopting a flat heat insulating container, and at the same time, the top of the flat heat insulating container can also be used as a mounting table for the hot water container. This allows the liquid inlet to be positioned at the required height to allow liquid to be poured into the hot water receiving container, etc., regardless of the flatness of the flat heat insulating container.

However, while the thinner and larger the planar extent of a flat insulation container is, the more preferable it is in terms of thermal efficiency, unless it is used effectively, such as by placing a hot water receiving container on it, the planar extent will simply become large unnecessarily.In the conventional type mentioned above, the planar space is only used to install a small pump, and therefore is not fully utilized.

In addition, the overall height of the electric pot itself is increased in order to make the liquid injection port the required height for the liquid injection pipe, but in the cited example, only a pump with a small height dimension is installed, which takes up space in the height direction. It is not used effectively enough, and a lot of space in the height direction is wasted.

As a result, the overall bulk of the flat heat insulating container becomes large compared to its capacity, and it is difficult to provide a flat electric pot with a large capacity. For this reason, the remaining amount of the liquid content tends to decrease and must be replenished frequently, and even if hot water is repeatedly supplied, it is not possible to maintain a constant level of liquid at all times and supply hot water at a constant temperature.

The object of the present invention is to provide a flat electric pot that can solve such problems.

In order to achieve such a purpose, the present invention is a flat type electric pot equipped with a pump that erects a liquid injection pipe from inside a flat type heat insulating container equipped with a heater and pushes out the contents through the liquid injection pipe. The liquid supply tank and the pump are arranged adjacent to each other with the liquid injection pipe within a plane area of the flat heat insulating container and within a height range that is approximately the same as the liquid injection pipe. .

Due to such a configuration, the present invention has a liquid supply tank and a pump arranged adjacent to the liquid injection pipe within the plane area of the flat heat insulating container and at almost the same height range as the liquid injection pipe. This can be provided by effectively utilizing the plane space of the mold heat-insulating container and the height space provided by the liquid injection pipe.

The liquid supply tank and pump provided in this manner can be provided with sufficient capacity within the height range of the required height of the liquid injection pipe, and without unnecessary planar expansion of the flat heat-insulating container.

The liquid supply tank can replenish the liquid contained in the flat heat-insulating container as it is consumed.

The present invention will be explained in detail below based on embodiments shown in the drawings. The first embodiment of the present invention, shown in FIG. 1, is an air injection type flat electric pot in which the present invention is applied. Inside the flat case 1 in the shape of a flat rectangular box, there is a metal inner container 2 that is slightly smaller than the case 1.
A heater 3 is provided at the lower part of the outer peripheral surface of the inner container 2 so as to surround the inner container 2. There is an opening 4 on the upper right side of the case 1.
This is closed with a lid 6 attached to the case 1 using a pivot 5 so as to be openable and closable. This lid 6
The top surface 7 of the lid 6 is formed flat and serves as a mounting surface for a pot or the like, and the lid 6 is provided with a knob 40 for convenient opening and closing. A bellows storage tube 8 is provided upright at the left end of the case 1, and a bellows pump 9 is disposed within this bellows storage tube 8. This bellows pump 9 has guide grooves 10 and 1 in a bellows storage cylinder 8.
The air is compressed by a push plate 11 that moves up and down while being guided by the pressure plate 11, and acts to forcefully feed air into the inner container 2 through an air supply hole 12 provided at its lower end. 13 is a hook valve, 14 is a restoring spring, and 15 is a vertically elongated guide hole provided on the left side of the bellows housing tube 8.

A liquid injection pipe support case 16 is provided upright in the center of the case 1, and an inverted J-shaped liquid injection pipe 17 is disposed within the case 16. This liquid injection pipe 17 passes through the inner container 2, and its base end (lower end) 18 reaches near the bottom plate 19 of the inner container 2 and opens, while its tip (upper end) 20 is located above the lid 6. It opens downward at.

A liquid supply tank 21 that can be removably fitted onto the case 1 is arranged between the bellows pump 9 and the liquid injection pipe 17. It is preferable that the liquid supply tank 21 is made of transparent or translucent synthetic resin, since this allows the amount of liquid in the liquid supply tank 21 to be observed from the outside. This liquid supply tank 21 has a handle 2 on the bottom (located at the top in Figure 1).
2, and a cap part 24 which is removably screwed onto the top of the body part 23 (located at the bottom in FIG. 1). A small diameter cylindrical liquid supply part 25 is formed in the cap part 24,
The liquid supply section 25 is provided with a valve 26 that stops the liquid supply to the inner container 2 when the liquid level in the inner container 2 reaches a predetermined value. In this embodiment, the liquid supply section 2
A small-diameter liquid supply port 27 is provided on the distal end surface 25a of 5, and a valve seat 28 is formed on the upper part of the periphery.
A rubber valve body 29 is disposed on the valve seat 29, and a protruding rod 30 that protrudes outward from the liquid supply port 27 is fixed to the valve body 29, and the tip flange 30a of the protruding rod 30 and the liquid supply port 29 are fixed to the valve body 29. A compression spring 31 is interposed between the protruding rod 30 and the distal end surface 25a of the portion 25 to bias the protruding rod 30 in the protruding direction, thereby forming the valve 26.

The liquid supply tank 21 is removed from the case 1,
By unscrewing the female and male screws 24a and 24b of the cap portion 24 and removing them, the reserve liquid can be injected into the interior thereof. The liquid supply tank 21 filled with liquid can be carried upside down as shown in FIG.
9 closely contacts the valve seat 28 and closes the liquid supply port 27, so that the liquid inside does not leak. Next, this liquid supply tank 21 is inserted into the case 1 as shown in FIG.
When it is inserted and set, the tip flange 30a of the protruding rod 30 hits the bottom plate 19 of the inner container 2 and is pushed up, so the valve element 29 floats up from the valve seat 28, the liquid supply port 27 opens, and the liquid supply port 27 opens. The liquid in the liquid tank 21 is supplied into the inner container 2. When the liquid level in the inner container 2 rises and becomes the same height as the tip surface 25a of the liquid supply part, the liquid in the liquid supply tank 21 and the liquid in the inner container 2 are in communication with each other, and due to the pressure balance, The supply of liquid from the liquid supply tank 21 to the inner container 2 is stopped.

In order to pour out the liquid in the inner container 2 to the outside through the liquid injection pipe 17, as is well known, the push portion 11a of the push plate 11 is pressed down to compress the bellows pump 9 and the liquid is poured into the inner container 2. All you have to do is pump the air.
In this way, when the liquid injection operation is performed, the level of the liquid in the inner container 2 falls and is located below the tip surface 25a of the liquid supply part, but again the valve 26
Due to this action, liquid is supplied from the liquid supply tank 21 to the inner container 2. Thus, while the liquid is present in the liquid supply tank 21, the liquid level H in the inner container 2 is kept constant. Further, the liquid within the inner container 2 is heated by the heater 3 and maintained at a predetermined temperature.

In FIG. 1, reference numeral 32 denotes a partition plate that divides the internal space of the inner container 2 into left and right sides to allow easy pushing operation of the bellows pump 9, and fluid is communicated only below the partition plate. Further, 33 is a recess provided on the upper surface of the case 1 in order to fit the liquid supply tank 21 and support it in a stable state. Furthermore, 41 is a gasket placed on the edge of the case opening 4, 42 is an annular gasket, and 43 is a liquid injection pipe 17.
44 is a case leg member.

A second embodiment of the present invention shown in FIG. 2 allows the liquid level H to be adjusted, and a liquid supply pipe 45 is provided separately from the body 23 of the liquid supply tank 21.
This can be screwed onto the body part 23 using the threaded part 46 and set with a nut 47, and the liquid supply cylinder 45 is provided with a valve 26 similar to the first embodiment. . In this embodiment, the liquid level H can be adjusted by adjusting the protrusion amount K of the liquid supply tube 45.

The third embodiment of the present invention shown in FIG. 3 also implements the present invention in an air injection type flat electric pot, but a liquid supply port 34 is provided on the upper surface of the liquid supply tank 21 in FIG. By removing the cap 35 screwed here, liquid can be supplied into the liquid supply tank 21, and the liquid supply part 25 of the liquid supply tank 21 (formed on the upper surface of the case 1). The liquid level H in the inner container 2 is adjusted using the float valve 26.
When it reaches a predetermined value, the liquid is removed from the liquid supply tank 21 to the inner container 2.
It is characterized by being configured so that the liquid supply to the tank is stopped. The other configurations are the same as those in the first embodiment (in FIG. 3, parts common to those in the first embodiment are given the same reference numerals). In addition, in FIG. 3, 36 is a float, 37 is a conical valve body that opens and closes the liquid supply port 27 of the liquid supply tank 21, 38 is a swing arm, 3
Reference numeral 9 denotes a bearing member for pivotally supporting the base end of the swing arm 38, and these and the liquid supply port 27 constitute the float type valve 26.

The operation of this embodiment is basically the same as that of the first embodiment, so the explanation will be omitted.

The present invention can be configured in various ways other than those shown in the above embodiments. For example, in the embodiment described above, the pump 9 for dispensing the liquid in the inner container 2 through the liquid injection pipe 17 is configured with a bellows pump, but it can also be configured with an electric pump.

According to the present invention, the liquid supply tank and the pump are arranged adjacent to each other with the liquid injection pipe within the plane area of the flat heat insulating container and within the same height range as the liquid injection pipe. The liquid tank and pump can be installed by making effective use of the flat space of the flat heat insulating container and the height base of the liquid injection pipe, and the liquid supply tank and pump can be installed within the required height range of the liquid injection pipe. Moreover, it can be provided with sufficient capacity without the needless planar expansion of a flat heat-insulating container.

In addition, the liquid supply tank can store makeup water and replenish the liquid contained in the flat heat-insulating container as it is consumed.
