Description

[Detailed description of the invention] This invention relates to a valve device that automatically opens and closes the filter container outlet of a coffee dispenser by inserting and removing a coffee receiving pot. To provide a valve device having a relatively simple structure that is mechanically reasonable and capable of reliably opening and closing the filter container outlet by insertion into the filter container and pulling it out from that position, and the coffee liquid flowing down from the filter container outlet is It is an object of the present invention to provide a valve device that is devised to prevent splashing when it hits the open valve portion located below the discharge port, or from being transmitted to the valve arm and dripping out of the pot.

An embodiment of this invention will be described in detail below with reference to the drawings.

Fig. 1 is a schematic side view of a coffee dispenser equipped with the valve device of this invention with the pot removed, and Fig. 2 is an enlarged sectional view of the same coffee dispenser with the pot installed. The main body of the pourer, 2 having a substantially U-shaped side surface, is a cartridge-type water tank that is detachably inserted into the back of the main body, and is housed in a tank cover 4 having a see-through window 3.

At the bottom of this water tank 2 is a tank insertion port 6 for the water tank holder 5.
A spring-biased water stop valve 7 is provided which opens when inserted into the water tank 2 and automatically closes when the water tank 2 is pulled upward.

8 is a U-shaped heater supported inside the main body base 1A via a die-cast base 39, and 9 is superimposed on this heater or adjacent to the heater 8 on the same plane (in the figure, the heater is The inlet side is connected to the tank insertion port 6 via a heat-resistant tube 10 (for example, a silicone rubber tube). A hot water rising pipe 11 is connected to the water inlet 6a and to the outlet side of the water heating pipe 9 via a silicone rubber pipe.

12 is a filter holder having a hot water spout 13;
A boiling water rising pipe 11 is connected to a connection port 14 protruding into the upper lid 1B of the main body.
The upper bent end of is inserted.

A cylindrical filter case 15 is detachably held below the filter holder 12, and a filter container 16 is held within this case.

The filter container 16 is equipped with a coffee waver 17 for filtering and dispensing the coffee powder a placed in the waver.
A protrusion 16a is provided to prevent 7 from coming into close contact with each other, and a discharge port 18 for dispensing coffee liquid is provided at the center of the bottom.

Reference numeral 19 denotes a pot holder having a top I/bottom positioning part 19a, and a heater heating plate 20 for keeping the pot warm is attached thereto.

21 is a glass pot with a handle 22 that is inserted and set on the lower side of the filter container 16, and is equipped with a lid 23 that can be opened and closed.

Note that this pot lid 23 is provided with a circular bulge 24 that projects slightly upward, and the outer peripheral surface of this circular bulge is aligned with the inclined surface 2.
4a, and the upper surface of the circular bulge 24 is formed by an annular flat surface 24b and a tapered surface 24C that gradually slopes gently downward toward the coffee injection hole 25 in the center. The coffee liquid flowing out from the outlet 18 is introduced into the pot as indicated by the arrow in FIG.

Reference numeral 26 designates a valve device of this invention that opens and closes the filter container outlet 18, and this valve device is located at the lower end (bottom surface) of the filter container 16 and is located behind the container outlet 18 (backward with respect to the pot insertion direction A). A pair of support pieces 27 a and 27 b that are protruded from each other and are spaced apart from each other in the left and right directions, a valve arm 29 whose intermediate portion is pivoted by a pin 28 so as to be able to rotate vertically between the support pieces, and this valve arm 29 . A conical valve-shaped closing plug 30 made of silicone rubber that is fixed to the arm and closes the discharge port 18 from below, and a spring 31 that biases (rotationally deflects) the valve arm 29 in the valve closing direction. (as shown in Figures 3 and 4).

The valve arm 29 is provided with a valve mounting portion 32 having a hole into which the shaft portion 30a of the blocking plug 30 is fitted, at a front end position facing the container discharge port 18, and surrounds the periphery of the valve mounting portion. A flat liquid receiving tray 33 is attached to the arm periphery 3.
3a and an inner partition wall 33b, and a discharge hole 34 is provided at the bottom of the saucer for allowing the coffee liquid that has flowed into the saucer 33 to flow out to the pot 21 side.
Further, a pot lid abutting protrusion 35 is provided protruding from the lower side of the rear end of the valve arm 29.

This protrusion 35 connects the glass pot 21 to the filter container 16.
When inserted into the lower side of the pot lid 23, the inclined surface 24 of the pot lid 23
The flat surface 24 on the top surface of the circular bulge 24 is pushed up by a
By riding on the valve arm 29 as shown in FIG. 2, the valve arm 29 is rotated in the valve opening direction.

36 is a spring fitting protrusion protruding from the bottom of the filter container 16; 37 is a pot lid abutting protrusion 35 of the valve arm 29;
The spring fitting hole protrudes from the upper part of the spring 3.
1 is interposed between the spring fitting opening 37 and the spring fitting protrusion 36, and is fitted and supported so as not to fall off.

In FIG. 1, reference numeral 38 is a starting switch, and 39 is a power cord. When the plug 39a of this power cord is inserted into the power source and the starting switch is turned on, the heater 8 heats up and the water is introduced from the water tank 2 side. The water in the water heating tube 9 is heated to about 90°C.

The hot water heated to a high temperature by the water guide heating pipe 9 is guided by the riser pipe 11 and is injected into the coffee liquid seal 17 from the hot water spout 13.

The coffee liquid that has passed through the liquid seal 17 flows downward from the container outlet 18, and the valve arm 2 which is in the open state
A liquid receiving tray 3 formed around the stopper head 9.
3, flows down from the discharge hole 34 at the bottom of the saucer to the upper surface (above the tapered surface 24C) of the pot lid 23, and is injected into the pot 21 through the coffee injection hole 25 in the center and stored.

In this case, coffee pouring continues until all the water in the water tank 2 is exhausted, and when all the water in the water heating pipe 9 has been discharged, a thermistor (not shown) is installed to detect the temperature rise in the water heating pipe 9. ), the alarm device (buzzer) sounds,
It will notify you when coffee pouring is complete.

Here, the pot 21 is taken out from the coffee dispenser and used for drinking, but in this case, the pot 21 is
When the valve arm 29 is pulled out and removed, the valve arm 29
is rotated in the valve closing direction by the elasticity of the arm, and the blocking plug 30 at the tip of the arm closes the outlet 18 of the filter container 16.
The remaining liquid in the filter container 16 is prevented from dripping onto the main body base plate 1A.

The valve device of the filter container outlet in the coffee dispenser of this invention has the above-mentioned valve arm rotating structure, but the filter container outlet 18 is moved by inserting and removing the pot 21 that receives the brewed coffee liquid. It is possible to provide a valve device that can reliably open and close the valve and has a mechanically reasonable and relatively simple structure.

In this valve device, a conical valve-shaped blocking plug 30 is attached to the front end of the valve arm 29 to block the filter container outlet 18 from below, and a liquid receiving plate surrounding the valve mounting portion 32 is provided. A portion 33 is formed so that the coffee liquid flowing down from the filter container discharge 1] 18 is once received in the flowing liquid receiving tray portion 33, and is configured to flow to the pot 21 side from the discharge hole 34 at the bottom of the receiving tray. from,
The coffee liquid flowing down from the filter container outlet 18 may hit the open valve part and scatter, or
This can prevent water from dripping outside the pot.
