Description

[Detailed description of the invention] This invention relates to an automatic pouring device for brewing coffee, green tea, black tea, etc.

Conventionally, this type of device used as a coffee maker and the like generally uses tap water for convenience, and disinfection and sterilization agents in the tap water deteriorate the taste of the brewed coffee.

Therefore, a system was developed in which the water in the water tank flows into the hot water supply route through an activated carbon filter installed near the bottom of the water tank, so that impurity-free water is supplied for hot water supply.
It is known from Publication No. 39095.

However, the filter is located at the bottom of the water tank and is not easy to attach or remove for cleaning or replacement, which is particularly difficult when the water tank is fixed.

Moreover, because the filter is located in the middle of the water supply in the water tank being supplied to the pouring process, it creates unnecessary resistance to the water supply, and also increases water flow resistance over time due to the capture or adsorption of dirt and impurities. This increase, together with the drop in the water level, lowers the water supply pressure, making it impossible to expect stable pouring.

Furthermore, since the filter is left immersed in the water supply for a long time, there is a risk that the water supply may be contaminated by the proliferation of adsorbed or attached bacteria.

This idea is an automatic pouring system that eliminates the drawbacks of the conventional method by providing a removable furnace material for convenient handling so that the water tank can filter the water when it receives water from outside. The purpose is to provide equipment.

Therefore, this invention is an automatic hot water pouring device that heats and boils water in a part of the hot water supply path connected to the water supply tank or in a sealed water tank and sends it to the pouring port at the end of the hot water supply path. A furnace material accommodating part capable of receiving water from above the lid and having a water outlet to the water tank at the lower part is provided on a part of the removable lid body that opens and closes the upper opening of the water supply tank, and the furnace material accommodating part In order to achieve the above object, the main idea is to load the furnace material so that it can be taken in and taken out.

To explain the embodiment shown in FIGS. 1 to 3, 1 is a main body, a container 2 for receiving coffee, tea, etc., and a filtration container 3 such as a filter cup or a tea cup. It is provided with a mounting table 4 to be stacked, and an upright part 6 which is integrally provided on one side of the mounting table 4 and whose upper part is a water tank 5.

A hot water supply path 7 is connected to the bottom of the water tank 5 via a check valve 8, and the middle of this hot water supply path 7 is buried adjacent to a heater 10 in a heating plate 9 provided on the above-mentioned mounting table 4. An instant water boiler type heating unit 12 heats and boils the water flowing from the waist water supply tank 5 into the hot water supply path 7 and sends it to the pouring port 11 at the end of the hot water supply path 7 without causing it to flow back into the water supply tank 5 through a check valve 8. It also serves to keep things on the mounting table 4 warm.

The hot water supply path 7 has a portion from the heating section 12 to the pouring port 11 side that passes through the water supply tank 5 and rises up, rising above the same kind of water tank 5 .
It is laterally extended outward in the same direction as the mounting table 4, and the pouring spout 11 is opened downward on the filter container 3 on the mounting table 4.
The hot water sent out is poured into a filter container 3 to make coffee, green tea, black tea, etc., and is stored in a receiving container 2.

A lid body 13 having a relief part 13a for the hot water supply path 7 is removably attached to the upper end opening 5a of the water tank 5 by a solder fitting 14 or the like. A furnace material accommodating portion 15 is provided in which the material 16 is filled.

The furnace material accommodating portion 15 is integrally molded with a lid 13 in which a furnace chamber 17 filled with furnace materials 16 is recessed downward, and has a bottom portion serving as a water outlet 18 to the water supply tank 5 and an upper end opening 19.
An auxiliary lid 20 is provided at the auxiliary lid 20, and one edge of the auxiliary lid 20 is connected to the edge of the opening 19 by a pivot type hinge 21 so that it can be opened and closed.

20a is a handle portion for opening the auxiliary lid 20.

The furnace material 16 is formed by forming activated carbon particles etc. into a block body, or
If used in a removable cassette type packed in a liquid-permeable bag or box, it is convenient for handling such as cleaning and replacement.In this case, since the furnace material particles etc. do not fall loose, Even if the water outlet 18 is not a porous type as shown in the figure, as long as the single furnace material 16 can be prevented from falling off,
It can also be one large opening.

The projecting portion 7a of the hot water supply path 7 is removably fitted 22 to the base side, and is designed to be detachable.

The furnace material accommodating portion 15 may be provided integrally with the lid 13 so as to form a part thereof, or may be separate from the lid 13 as shown by the imaginary line in FIG.

When pouring the required amount of water into the water supply tank 5 to make coffee or the like, the auxiliary lid 20 is opened and the water is poured from the furnace material storage part 15.

The water poured from the furnace material storage section 15 passes through the furnace chamber 17 and is purified by the furnace material 16, and then flows out into the water supply tank 5.

Therefore, the water supplied from the water tank 5 for pouring hot water has been purified by filtration, and even if tap water is used quickly, impurities such as disinfectants and sterilizers that have been mixed in have already been removed. Because of this, the taste of freshly brewed coffee, etc. improves.

Furthermore, the filtration can be carried out by simply pouring water into the water tank 5 as usual, and no special work is required.

4 and 5 show an embodiment in which the furnace material storage section 15 itself serves as a lid 13 and is attached to and detached from the water tank, and the lid 13 connects the furnace chamber 17 to the water tank. Fit it into the opening of
The upper end flange 13b is seated on the mouth edge of the water tank so as to be removably attached, and the auxiliary lid 20 is integrally molded so as to be continuous with one edge of the flange 13b by a thin hinge part 30, so that it can be opened and closed. ing.

As shown in FIG. 6, the heating section 12 recesses a part of the bottom of the water supply tank 5, and heats the starting end opening 41 of the hot water supply path 7 through the backflow suppressing plate 40 into the water supply tank 5 at the opening 42a. A recess 42 is provided, and the supplied water flowing into the recess 42 is
The heater 10 on the outer periphery of the concave portion 42 heats and boils the water, and the hot water is routed through the hot water supply path 7 without flowing back into the water tank 5.
Of course, this invention can be applied to a so-called percolator-type device that sends water through a heater 1, as shown in FIG.
It is also possible to adopt a type in which the boiling water is directly heated to boiling temperature at 0, and the pressure inside the tank 5 is thereby increased to send the boiled hot water through the hot water supply path 7.

In this case, the furnace material accommodating portion 15, which is detachably attached to the opening 5a of the water tank 5 by screwing 50 or the like, is also used as the lid 51 as in the embodiment shown in FIG. The auxiliary lid 20 is provided with a frame 53 that is elastically fitted 52 into the upper end opening 19 of the furnace chamber 17 and seals the furnace material storage section 15, so as not to impair the automatic pouring function due to the internal pressure increase.

In FIGS. 6 and 7, reference numeral 43 denotes a heat-retaining heater provided separately on the four parts of the mounting table.

According to this invention, in an automatic hot water pouring device that heats and boils supplied water in a part of the hot water supply path connected to the water supply tank or in a sealed water supply tank section and sends it to the pouring port at the end of the hot water supply path, A part of the removable lid that opens and closes the upper end opening of the water tank is provided with a furnace material storage part that can receive water from above the lid and has a water outlet to the water tank at the bottom, and the furnace material storage part is Since the reactor materials are loaded in and taken out freely, water can be purified and supplied to the water tank through the reactor material accommodating part without changing the normal form of a part of the lid, its attachment/detachment, transportation, etc. This method does not make handling complicated or bulky, and eliminates the effects of increased water supply resistance to the pouring path due to immersion of the furnace material in the water supply, and the effects of bacteria that proliferate during long periods of disuse. Solve the problem mentioned.

In addition, the furnace material is attached to and removed from the furnace material housing part of the lid, which can normally be handled, and can be replaced, cleaned, and dried at a desired location as a small part separated from the water tank along with the lid. It is easy to clean and can improve hygiene by promoting furnace material management.
