DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to various kinds of liquid containers such as electric pots, and more particularly, to a liquid discharge container which rises from a connection portion with a bottom of a container between an outer case and an inner container of the container, and is directed downward from the container. The present invention relates to a liquid container provided with a pouring path leading to the liquid container, wherein the rising portion of the pouring path has a liquid amount display section.

[0002]

2. Description of the Related Art Heretofore, the discharge path of this type of liquid container has been arranged on a vertical plane passing through the center of the body so that the liquid amount display portion and the discharge port are arranged at the same position around the side circumference of the body. (For example, Japanese Utility Model Laid-Open No. 62-202227). And the discharge port is located on the outer surface of the outer case of the instrument body as it is or by applying a pipe cover, and the liquid amount display part is located inside the outer case and is seen through from the outside through the display window opened in the outer case. It has become so.

[0003]

However, in the conventional structure described above, the position where the display window is to be provided overlaps with the position of the discharge port on the front face of the body where the discharge port is located.
For this reason, the display window is provided only in a range not obstructed by the discharge port. In particular, when a discharge port or a liquid injection guide tube provided subsequently thereto is designed so as to be covered with a pipe cover, as in recent times, a range in which a display window is provided is further reduced.

In view of this, a liquid amount display portion is provided around the side circumference of the body by swinging it from the position of the front surface having the discharge port, that is, by swinging in the side circumference direction of the body to provide a liquid amount display portion. The quantity indicator tube is provided separately from the pouring line (62-1)
No. 89022, JP-A-1-259809, JP-A-1-153134, etc.) are known. In this configuration, it is necessary to provide the liquid amount display tube separately from the pouring path, which complicates the configuration.

[0005] Further, there is also a configuration in which an injection path and a liquid amount display tube are used in common (Japanese Utility Model Laid-Open No. 1-11542, etc.).
In this configuration, since the spouting path is horizontally swung halfway, when the liquid returns after ejection, it is likely to accumulate at the horizontal portion of the spouting path and hinder the flow. It does not have a water-stop configuration when falling, which is indispensable from the safety standards of the above, and it is easy for hot water to flow out when falling.

Accordingly, the present invention provides a liquid container which can improve the liquid amount display form by the pouring path together with the installation structure of the pouring path and the water stop valve at the time of overturn, so that the above-mentioned conventional problems can be solved more advantageously. It is an object to provide

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a downward discharge port which rises from the bottom of a container to the exterior case of the container and faces the outside of the container. In the liquid container provided with an outlet path leading to the outlet, the rising portion of the outlet path as a liquid amount display section, and a pipe cover provided to cover the outlet path leading to the downward discharge port, a liquid amount display window provided in the outer case. Is positioned in the side circumferential direction with respect to the front of the pipe cover, and the liquid amount display window of the outer case is opposed to the liquid amount display portion of the injection path, and the injection path is

A water stop valve for overturning is provided near the lower plate of the pipe cover in the spout that rises in the pipe cover from the joint pipe position, and the outside diameter of the valve chamber of the water stop valve for overturn is determined as the outside diameter of the spout. And the distance between the inner container and the outer case is smaller than the outer diameter of the valve chamber.

[0008]

According to the above construction of the present invention, the spouting path leading to the discharge port is displayed by the liquid level display window which is swung in the circumferential direction of the body, so that the spouting path itself is measured by the liquid level. By using the display portion, the liquid amount can be displayed as the liquid amount display passage through the liquid amount display window provided in the outer case without providing a special liquid amount display passage other than the liquid discharge passage. At the same time, the liquid level display can be positioned in the circumferential direction of the body, and even if a sufficient amount of liquid level display window and pipe cover are provided, the required height range using the full length of the normal body Can be provided. Therefore, the liquid amount can be displayed while covering the required fluctuation range of the liquid level in the inner container.

Since the liquid is maintained, the liquid easily flows down to the inner container side by utilizing the upward gradient of the portion of the body of the pouring path that is swung in the circumferential direction, and does not prevent the liquid after being discharged from returning. Furthermore, the spouting path can be positioned along the lower plate of the pipe cover by using the swinging of the spouting path in the circumferential direction of the vessel. By providing the water stop valve at the time of falling close to the plate, the water stop valve at the time of falling is located in the large space formed by the pipe cover, so that the outside diameter of the valve chamber does not become large and the outside diameter of the injection passage Larger than that, to accommodate a valve that is large enough to provide a water stop function in the event of a fall. Further, the distance between the inner container of the container body and the outer case is made smaller than the outer diameter of the valve chamber, and the outer case is reduced in diameter regardless of the outer diameter of the valve chamber until the discharge path enters between the inner container and the inner container. The outer diameter of the container can be reduced.

[0010] In particular, by providing the spouting path along the lower plate of the pipe cover and providing the spouting path rising from the position in the pipe cover with the overturning water valve close to the lower plate of the pipe cover, The space inside the pipe cover can be used effectively, and the pipe cover can be made compact despite the installation of the water stop valve. The exit can be located higher.

As a result, it is possible to eliminate the liquid pool at the connecting pipe 28 which is turned sideways in order to connect the liquid amount display portion 21a which has been shaken sideways to the discharge port 22. It should be noted that the present invention is not limited to the above embodiments, but can be implemented in various modes. For example, a connection portion and a connection structure with the container 3 for holding the liquid amount display portion 21a on the container 3 can be variously designed.

FIGS. 6 and 7 show a third embodiment of the present invention. In the first embodiment, the liquid amount display portion of the discharge passage 21 is provided so as to swing sideways with respect to the unit 26. Unit 2
6, there is provided a liquid level detecting unit 51 for ensuring a safe liquid level as shown in FIG. The liquid level detection unit 51 has a vertical pipe 52 provided so that the upper and lower ends communicate with the inner container 2, and a full water level detection float 53 and a minimum water level detection float 54 are accommodated in the vertical pipe 52. .

The float 53 detects an upper limit water level, that is, a full water level, which can prevent the content liquid from flowing out naturally through the spouting channel 21 due to fluctuations in the liquid level when the content liquid boils. To detect this, a reed switch 56 for detecting the magnet 55 in the float 53 at a position corresponding to the full water level is provided at a predetermined position.

The float 54 detects a minimum water level at which a danger of empty cooking occurs due to a small amount of liquid content. To detect this, a reed switch for detecting a magnet 57 in the float 54 at a position corresponding to the minimum water level. 58 is provided at a predetermined position.

These reed switches 56, 58
Is connected to the heater control circuit 61 shown in FIG. Circuit 61
Has a warming heater 6a and a water heater 6b, and the relay 64 is turned on depending on whether the content liquid is lower than the minimum temperature and the water heater is turned on and the thermostat 62 is turned on or the reboil switch 63 is turned on artificially. It is turned on with the self-holding by the contact 64-1, the contact 64-2 is kept in the on state, and the heaters 6a and 6b are set to the electric water heating mode. When the content liquid boils in the water heater mode, the boiling sensor is turned off, the relay 64 is turned off, and the contact 64-2 is turned off to switch to the heat keeping mode in which only the heat keeping heater 6a is energized.

Such an operation state is determined by the two reed switches 5
This is possible because each of the switches 6 and 58 is in the ON state without detecting the magnets 55 and 57.
If any one of 58 detects the magnets 55 and 57 and is turned on, that is, if it detects whether the water level is full or the lowest, the power supply to the heaters 6a and 6b is cut off and safety is ensured.
At this time, the water level display lamp 66 is turned on to visually indicate to the outside that the water level is abnormal.
