Description

[Detailed Description of the Invention] This invention relates to a so-called percolator type or instant water boiler type automatic pouring device used in coffee makers and the like.

Conventionally, regardless of whether it is a percolator type or an instant water boiler type,
The supplied water is heated to boiling point in the 7th part of the hot water pouring path and sent out to make coffee or tea, and the heating does not reach much or at all to the water in the water tank. , the water supply is heated only once during pouring, and the efficiency of boiling it is poor, and the delivery of hot water is not sufficient, so water can only be poured intermittently, or even if it can be poured continuously, the flow rate is low. It tends to be unstable.

In addition, the pouring path after passing through the heating section is generally provided to rise up to the required height in the water supply tank, and hot water that is sent out at a small flow rate suitable for the purpose is easily deprived of heat and has the poor efficiency described above. The temperature of the hot water does not rise sufficiently after being heated once, and when it passes through the water tank it exchanges heat with a large amount of water that remains at room temperature, so the actual temperature of the hot water that is poured is This results in a considerably low temperature, which cannot be fully satisfied with coffee, etc., which must be made at a high temperature.

Furthermore, the start time of pouring depends on the device, which is inconvenient and dangerous, and the total amount of pouring and the end time of pouring are determined by the amount of water supplied, so there is a risk of making a mistake in the amount of water supplied or changing the amount of pouring midway through. In this case, it is difficult to adjust because the excess water in the water tank must be pumped out.

The object of this invention is to provide an automatic pouring device such as a coffee maker, which has a simple structure and can overcome the above-mentioned drawbacks.

To explain the embodiment shown in FIGS. 1 to 3, an example is shown in the case of a percolator type automatic pouring device, where 1 is a water tank having a heating recess 2 recessed downward in the center of the bottom, and 3 is a water tank having a heating recess 2 recessed downward in the center of the bottom. a mounting table having a heater 4 that removably receives the water supply tank 1 and heats the heating recess 2 from around the outside;
5 has a lower end opening 5a facing into the heating recess 2, and a backflow suppressing plate 6 located at the opening of the recess 2 to prevent water flowing into the recess 2 from flowing back into the water tank 1. The water that has flowed into the recess 2 is heated and boiled by the heater 4, and it has more resistance to flow into the hot water pipe 5 and rise than to flow back through the plate 6 into the tank 1. Since the is extremely small, the hot water boiled in the recess 2 is sent to the hot water pipe 5.

Therefore, the backflow suppressing plate 6 can be replaced with a check valve.

A hot water receiving chamber 8 is provided at the upper end of the hot water pipe 5, and the hot water receiving chamber 8 is installed so that the hot water pipe 5 passes through the bottom plate 7 and the hot water pipe upper end opening 5b faces inside. Water tank 1 on the outer periphery
It is held detachably and rotatably in an opening 10 concentric with the tube 5 of the lid 9 attached detachably to the opening 10 of the bottom plate 7.
An outflow port 11 is opened at one eccentric position in a range facing into the water tank 1, and one end of the hot water receiving part 12a moves along a circular movement trajectory 18 due to rotation around the pipe 5 of the chamber 8 of the outflow port 11. The terminal pouring path 12 facing downward and having the other end pouring port 12b protruding to the side of the water tank 1 is integrally molded into the lid 9 in the form of a bridge with an open top.

10a is a stepped portion for holding the chamber 8 into the opening 10; 13 is a transparent dome cover placed over the bottom plate 7 of the chamber 8; 14 is the chamber 8;
15 is an operation piece for rotating the chamber 8. The indication piece 14 and the operation piece 15 are screwed 16 to the outer periphery of the bottom plate 7, and 15 is an operation piece for rotating the chamber 8.
3 to the bottom plate 7.

19 is a pouring path including the heating recess 2 of the water supply tank 1 to the terminal pouring path 12, and 20 is a heating section provided in a part thereof by the heater 4 for automatic pouring.

The above-mentioned mounting table 3 is located next to the first receiving part 21 that receives the water tank 1, and has a pouring port 12b of the terminal pouring path 12 that extends above the water tank 1 received on the receiving part 21. A second receiving section 24 is provided directly below on which a container 22 for receiving coffee, tea, etc. and a finished container 23 for filter cups, tea containers, etc. are stacked, and the receiving section 24 can also be heated if necessary. A heater 25 is provided.

26 is a power cord connection part.

The hot water receiving chamber 8 can be attached and detached together with the hot water pipe 5 and the backflow suppressing plate 6, and these and the lid 9 can be attached to the water tank 1.
Fill water into the same type 1 with the water removed from the holder, then attach the lid 9, the hot water receiving chamber 8, and the parts integrated with it, and connect the hot water receiving chamber 8 to the hot water pouring path where the outlet 11 ends as shown in Figure 2. The rotary position is such that it is removed from above the hot water receiving portion 12a of No. 12 and faces into the water tank 1.

When the heater 4 is energized in this state, the water flowing into the heating recess 2 is heated and boiled by the heater 4 and the hot water pipe 5
The hot water is sent into the hot water receiving chamber 8 from the upper end opening 5b and blows out in a fountain shape, and a part hits the back surface of the dome cover 13 and disperses and flows down into the chamber 8 and drips again.

In this way, the hot water that enters the chamber 8 is returned to the water receiving tank 1 from the outlet 11 at the bottom of the chamber 8, even though the temperature is initially low and the pumping of hot water is intermittent or the flow rate is unstable as in the conventional case. Ru.

As a result, the water in the water supply tank 1 is repeatedly heated by the heater 4 while being returned in the portion of the pouring path 19 excluding the end pouring path 12, and the water in the water receiving tank 1 gradually rises in temperature. Thus, the temperature and flow rate of the hot water pumped from the hot water pipe 5 into the chamber 8 are sufficient.

At this point, for example, the temperature sensing element 27 provided at the bottom of the water tank 1
electrical display, color display of a heat sensitive body (not shown) provided on the dome cover 13 that develops or changes color at a specific temperature,
Alternatively, it can be determined by various methods such as a regular thermometer.

When the temperature and flow rate reach sufficient conditions, the hot water receiving chamber 8
When the hot water is rotated so that the outlet 11 is positioned above the terminal pouring passage 12 as shown in FIG. ,
The molten metal flows to the pouring port 12b of the terminal pouring path 12 and the same pouring port 12b
It flows out and is poured.

This pouring continues until the hot water in the water supply tank 1 runs out, but if you wish to stop pouring in the middle, simply rotate the hot water receiving chamber 8 in the direction shown in Figure 2, and the hot water will flow into the chamber 8. Since the hot water is returned to the water supply tank 1, the pouring of hot water is stopped, and from then on, the hot water in the water supply tank 1 is kept at a constant temperature while being refluxed.

In other words, it is kept warm. The above-mentioned pouring can be started and stopped arbitrarily by manual operation as needed, which is convenient for use, eliminates the risk of unexpectedly starting pouring, and allows for free heating.

The embodiment shown in FIGS. 4 and 5 shows an example of an instant water boiler type automatic pouring device, in which a water tank 1 is fixedly provided above the upright portion 30a of the main body 30. In the middle of the pouring path 19, one end of which is connected to the bottom of the water tank 1 via the check valve 31, the same path pipe and the heater 4 are placed adjacent to each other.
A heating part 20 for automatic pouring of molten metal is provided buried in the water tank 1, and a part of the molten metal pouring path 19 after the heating part 20 is a hot water pipe that rises upward from below the bottom of the water tank 1 through the inside of the same type 1. It is 5.

A hot water receiving chamber 8 is detachably and rotatably fitted into the upper end of the hot water pipe 5, and a removable lid 9 of the water tank 1 is located immediately below the hot water receiving chamber 8. It has an opening 10 that is slightly larger than the locus of movement of the outlet 11 of the hot water receiving chamber 8 and can face into the water tank 1 no matter where the outlet 11 is located, and also retains a part of the terminal pouring path 12. It is intended to be inserted into the recess 33 and held detachably.

The terminal pouring path 12 is a conduit in which only the hot water receiving portion 12a is open upward, so as to prevent the hot water from coming into contact with the outside air and lowering the temperature, and to elastically engage the front and rear edges of the recessed portion 33. Engagement protrusion 34 for stabilizing in a certain position
It is formed.

The receptacle 32 is a receptacle integrally formed on the lower side of the upright portion 30a of the main body, and is placed below the container receiving portion 30b to help keep the space between the containers warm.

The pouring action is not much different from that of the previous embodiment, and its explanation will be omitted.

In each embodiment, the dome cover 13 is transparent and allows the user to observe the unique situation in which hot water flows out from the hot water pipe 5 into the hot water receiving chamber 8 in the form of a fountain, which arouses interest. In addition, it is made to determine whether or not the hot water is being pumped continuously at a stable flow rate, so that it can be determined whether or not it is safe to start the hot water pumping.

In addition, although the hot water receiving chamber 8 is described only when the direction is changed by rotation, that is, the position is changed, the external shape of the hot water receiving chamber 8 is made non-circular, for example, and it is said that the hot water receiving chamber 8 is mounted after being lifted and then changing its orientation. Various methods can be used.

Furthermore, the automatic pouring method heats a sealed water supply tank to bring the water in the tank to a boil, and the resulting rise in pressure inside the tank causes the boiled hot water to be sent out through the pouring path.
You can freely choose and use them.

According to this invention, in a hot water pouring path that has a heating part that heats and boils water and automatically sends it out, the hot water sent out from the heating part is placed at the upper end of the hot water pipe that guides the hot water upward in the water tank. , a receiving chamber is provided which can receive the hot water pumped through the intermediate pipe and return the hot water to the water supply tank depending on its orientation, or supply the hot water to the terminal pouring path to pour the hot water, and Since the pouring of hot water can be carried out selectively as appropriate, depending on the return of the hot water, the water in the water supply tank can be repeatedly heated and refluxed using a part of the pouring path having the heating section. The temperature rises, and the pouring of molten metal at a sufficient temperature and flow rate is performed stably.

Furthermore, the user can easily decide to start and stop pouring the hot water by simply changing the orientation of the hot water receiving chamber, eliminating the inconvenience and danger that would otherwise occur in the conventional case where the process is left to its own devices.

While the hot water pouring is in the stopped state, the heated hot water in the water supply tank is kept warm, and functions as an automatic hot water pouring device capable of pouring sufficient hot water at any time.

Furthermore, the structure is not complicated and can be provided at low cost.
