Abstract

PURPOSE:To enable sanitary cooking by stirring mixed liquid of hot water and a raw material sufficiently without dipping any body in the mixed liquid. CONSTITUTION:The hot water is injected from a hot water tank 6 into a cup 3 with a gush and the raw material 8 is solved in the hot water while stirred with the hot water. Further, a hot water feed pipe driving means 42 elevates a hot water feed pipe 34 as the hot water is injected, so a laminar flow part where the spread of the injection is small is stirred nearby the injection hole of the hot water feed pipe 34. Thus, the mixed liquid in the cut 3 is stirred sufficiently without dipping any stirrer in the mixed liquid. Consequently, the sanitary cooking is enabled.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vending machine that sells cooked food in cups.

A conventional cup-type vending machine is constructed as shown in FIG. In the sales operation, the cup dispenser 2 first dispenses the cup 3 to the cup station 1 located facing the product outlet, and then the raw materials A1 to A3 for one batch are transferred from the raw material tanks 4A to 4C to the mixing bowl 5. In the mixing bowl 5, raw material A is poured into the mixing bowl 5, and one batch of hot water B is poured from the hot water tank 6 of the water heater into the same mixing bowl 5.
1 to A3 are dissolved in hot water B, and the melted liquid C is poured into cup 3 of cup station 1, and one sales operation is completed by finishing the pouring. More specifically,
In a coffee vending machine, A1 is coffee powder, A2 is cream powder, and A3 is sugar.

In such a configuration, the mixing bowl 5 and the cup 3 from the mixing bowl 5 are used to dissolve the raw materials in hot water.
The piping 7 is an essential component and is not preferred from a sanitary point of view. That is, when used for a long period of time, dirt adheres to the inside of the mixing bowl 5 and the inside of the pipe 7, and the liquid C flowing from the mixing ball 5 to the cup 3 is contaminated with this dirt.

For this reason, some devices are constructed as shown in FIG. In the cooking process, first, as shown in FIG. 8(a), the raw material 8 is poured into the cup 3, and then, as shown in FIG. 8(b), hot water C is poured into the cup 3 into which the raw material 8 has been poured. At this time, hot water is flowing down from the hot water tank 6. Furthermore, the eighth
As shown in Figure (c), insert the screw 10 into the mixed liquid 9 in the cup 3 and stir to sufficiently dissolve the raw material 8.
Then, pull out the inserted screw 10 as shown in Figure 8 (
As shown in d), the product is a product in which raw material 8 is dissolved in hot water C. In this case, since the screw 10 stirs inside the cup 3, the mixing ball 5 and the piping 7 are not necessary.

Problems that the invention aims to solve In the vending machine that executes the cooking shown in FIG.

Since the mixing bowl 5 and piping 7 are not required, it is more sanitary than the vending machine shown in FIG. 10 and the same screw 10 is used repeatedly, there remains a factor that causes unsanitary conditions.

An object of the present invention is to provide a cup-type vending machine that can sufficiently stir a mixture of hot water and raw materials without inserting an object into the mixture.

Means for Solving the Problems The cup-type vending machine of the present invention vigorously injects hot water from a hot water supply pipe into a cup into which raw materials have been added, dissolves the raw materials while stirring with the injected hot water, and dissolves the raw materials in the hot water. The hot water supply pipe is characterized by being provided with a hot water supply pipe driving means for moving the hot water supply pipe upward from the bottom of the cup as the hot water is poured.

Function: According to this configuration, hot water is vigorously poured into the cup, and the raw materials are dissolved into the hot water while being stirred by the hot water.

Furthermore, since the hot water pipe driving means raises the hot water pipe as the hot water is injected, the agitation can be performed in the laminar flow portion near the spout of the hot water pipe where the spray spreads less.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 5. Components having the same functions as those in FIGS. 7 and 8 showing the conventional example will be described with the same reference numerals.

FIG. 1 shows a cup-type vending machine of the present invention.

In addition to a part that performs simple cooking by dissolving raw materials in hot water and discharging them, there is also an extraction filtration device 11 that performs cooking by filtering a mixture of raw materials and hot water to extract an extract. .

The extraction filtration device 11 is constructed as shown in FIGS. 2 and 3. Here, we will explain the case of cooking coffee powder with hot water as an example. A filtrate receiver 13 is attached to the lower part of the extraction chamber main body 12 so as to be able to rise and fall freely.
A band-shaped filter 15 pulled out from the wrapping body 14 is hung between the filter 2 and the filtrate receiver 13.

In the filtration process, the filtrate receiver 13 is raised and the extraction chamber main body 1
2, and then the upper chamber 18 of the extraction chamber main body 12 separated by a partition wall 17.
Coffee powder and hot water C are put into the upper chamber 18 of the lower chamber 19. Here, the communication hole 20 that communicates the upper chamber 18 and the lower chamber 19 is connected to a valve body 2 which is biased downward by a compression spring 21.
2, and a mixed liquid 23 of flour, flour, and hot water C is held in the upper chamber I8. In this state, open the valve body 22 to let the mixed liquid 23 flow down into the lower chamber 19, and from now on, the valve body 22 will be opened.
Pressurized air at atmospheric temperature is blown in from the air supply port 24 under the condition that the pressurized air is regulated so that it does not leak. In the state shown in FIG. 3, the mixed liquid 23 in the lower chamber 19 is
The brewing chamber side of No. 5 and the filtrate receiver are forcibly filtered due to the pressure difference between the sides, and the hot water component containing the dissolved coffee extract in the mixed liquid 23 passes through the filter 15 and flows into the flow passage 25, and flows into the cup 3. will be paid out to.

In FIG. 1, hot water C flows down from the hot water tank 6 to the extraction filtration device 11 via a first electromagnetic valve 26, and pressurized air flows via a second electromagnetic valve 27 to an air pump serving as a pressurizing means. Sent from 28.

When performing simple cooking in which the raw material 8 is dissolved in hot water C without using the extraction filtration device 11, the hot water C is poured into the cup 3 into which the raw material 8 has been placed in the following manner. A valve body 31 is provided in the upper opening 30 of the pressurized tank 29.
The lower opening 32 is connected to the hot water supply pipe 34 extending to the cup 3 via a check valve 33. The valve body 31 of the upper opening 30 is opened to allow the third water to enter the pressurized tank 29. The amount of hot water C used for one cooking flows down from the hot water tank 6 via the electromagnetic valve 35, after which the valve body 31 is held in a closed state. The opening 36 of the pressurized tank 29 has a fourth
Pressurized air is sent from an air pump 28 through a solenoid valve 37 . Note that an air filter (not shown) is interposed just in front of the opening 36. Here, since a check valve 33 is installed between the lower opening 32 of the pressurized tank 29 and the hot water supply pipe 34, when pressurized air is sent from the opening 36, the internal pressure of the pressurized tank 29 increases.

Hot water C will not be injected from the hot water pipe 34 into the cup 3 until this internal pressure rises to the specified value determined by the check valve 33. If the internal pressure of the pressurized tank 29 exceeds the specified value of the check valve 33, , pressurized hot water C flows from the hot water pipe 34 to the cup 3.
The raw material 8 in the cup 3 and the injected hot water C form a mixed liquid 9, and the mixed liquid 9 is stirred by the force of the injected hot water C, so that the raw material 8 is dissolved in the hot water C. Insert.

Here, as hot water C is injected into the hot water pipe 34, the controller 43 and the pulse motor 44, which constitute the hot water pipe driving means 42, are connected to each other.
and a rack 46 that is attached to the hot water pipe 34 and meshes with a pinion 45 that is attached to the output shaft of the pulse motor 44.
The motor is driven as shown in FIG.

The relative position of the cup 3 and the hot water pipe 34 immediately before the start of injection of hot water C from the hot water pipe 34 is such that the hot water pipe 34 is inserted into the cup 3 as shown by the solid line in FIG. 4(a), and the control unit 43 applies a drive pulse to the pulse motor 44 as the hot water C is injected. As a result, the hot water supply pipe 34 is connected via the pinion 45 and the rack 46 to a distance north of 1. AC 2 and hot water C injected sequentially
The hot water supply pipe 34 is driven upward to a position where the tip of the hot water supply pipe 34 does not touch the liquid mixture 9 of the raw material 8 and the water supply pipe 34.

By driving upward in this way, Figure 4 (,)
As shown by the imaginary line in , the following effects cannot be obtained when the hot water supply pipe 34 is fixed at a position where it does not come into contact with the mixed water from the start to the end of the injection of hot water C. hot water pipe 3
Regarding the distance from the outlet 4 and the spread of the hot water C injected, near the outlet of the hot water pipe 34 there is almost no spread and the state is laminar flow 1, and as it gets further away, the spread appears and becomes turbulent flow. Are known. When the hot water supply pipe 34 is fixed, if the distance between the outlet of the hot water supply pipe 34 and the liquid level of the mixed liquid 9 inside the cup 3 is large as shown in FIG. The above-mentioned turbulent flow (2) acts on the mixed liquid 9, and not only is a sufficient stirring effect not obtained, but the warm water C1 mixed liquid 9 may be scattered around, and the outer peripheral surface of the cup 3 may be soiled with the mixed liquid 9. . Also.

There is also a lot of foaming in the mixture.

On the other hand, when the hot water supply pipe 34 is driven upward by the pulse motor 44 as in this embodiment, the laminar flow part (2) is always used, and the hot water C1 mixed liquid 9 does not scatter and has a good condition with little foaming. A good stirring effect can be obtained.

In addition, as an example of the configuration of the control unit 43, the hot water and raw materials injected are controlled based on the internal pressure of the pressurized tank 29, the pressure of the pressurized air pipeline to the pressurized tank 29, or the internal pressure of the hot water supply pipe 34 and the elapsed time. The liquid level in the cup 3 determined from the total volume and the shape of the cup 3 is calculated, and the drive pulses are sequentially applied to the pulse motor so that the hot water supply pipe 34 is in a position where it does not touch the mixed liquid 9. Possible configurations include a configuration in which the driving pulse is applied to the pulse motor 44, and a configuration in which the driving pulse is applied to the pulse motor 44 in accordance with the elapsed time from the closing of the fourth electromagnetic valve 370 or the valve body 31.

In this way, the mixed liquid 9 in the cup 3 can be stirred using the pressure feeding energy of the injection of the hot water C without inserting a stirring device such as a screw IO, which is sanitary.

5 and 6 show a configuration for putting raw material 8 into cup C in the case of simple cooking using pressurized tank 29. Inside the exterior case 38 of the vending machine, there is a cup tray. In addition to the cup stocker table 40 on which Spencers 39A, 39B, and 39C are arranged, the raw material tanks 4A to 4C, and the hot water tank 6, an
A table 41A, a Y table 41B, and a robot hand 41G for grasping a cup are provided.

Here, a small 7 ounce cup is set in the cup dispenser 39A, and medium and large cups of 9 ounce and 12 ounce are stacked and set in the cup dispensers 39B and 39C.

When a sales execution instruction is detected, the cup dispensers 39A to 39 are activated based on the cooking data given at that time.
Determine which cup from C is to be used, and
Pulse motor Ml that drives Y tables 41A and 41B
, M2 to move the robot hand 41C in the standby position to the target position.

Assuming that the cup used here is a 7 ounce cup, the robot hand 4. The IC moves to a position below the cup dispenser 39A as shown in FIGS. 5 and 6, and the dispensed cup 3 is received by the robot hand 41G.

Next, the pulse motor Ml is used to apply the drive pulses necessary to move the raw material A1 discharged from the raw material tank 4A to the position where it is received.
, M2. When the application of this drive pulse is completed, the dispensing motor of the raw material tank 4A is operated for a specified period of time, and the raw material A1 is put into the cup 3 held by the robot hand 41G. When the dispensing operation of raw material A1 is completed, based on the cooking data, raw material A2 such as cream, sugar, etc. When A3 is required for cooking, the robot hand 41C is moved to the position for receiving the discharged raw material in the raw material tank 4B and the position for receiving the discharged raw material in the raw material tank 4C, and when the robot hand 41G arrives at the lower position of the raw material tank 4B. The dispensing motor of the raw material tank 4B is operated, and when it reaches the lower position of the raw material tank 4C, the dispensing motor of the raw material tank 4C is operated. Here, the case where cooking is performed using each of the raw materials A1 to A3 of the raw material layers 4A to 4C is explained as an example, but the raw material tank 4
It may pass through one or two raw material input positions A to 4C.

When all the raw materials necessary for cooking have been added, the cup 3 is transferred from the current position of the robot hand 41C to the cup station 1, and the cup 3 of the raw material input method is transferred.
is delivered to cup station 1.

In the above embodiment, the hot water C was injected from the hot water pipe 34 into the cup 3 at the cup station 1, but the hot water pipe driving means 42 was injected into the cup 3 from the hot water pipe 34 at the cup station 1, for example, on the way as shown in FIGS. The same effect can be achieved even if the hot water C is injected and stirred at this position, and the cooked food is transported to the cup station 1.

Further, the same effect can be obtained even if the extract from the extraction filtration device 11 is discharged through the hot water supply pipe 34.

Effects of the Invention As described above, according to the present invention, in order to pressurize hot water in a pressurized tank and then forcefully inject the pressurized hot water into the cup of the raw material injection method, a stirring device is installed in the mixed liquid in the cup. It is possible to stir sufficiently using the energy of pumping hot water without inserting water, making it possible to cook in a very hygienic manner.

Moreover, since the hot water pipe driving means pulls up the hot water pipe as hot water is injected, the hot water is injected by a laminar flow portion of the hot water.

An effective stirring effect can be obtained with less scattering.
