Abstract

PURPOSE:To dissolve raw materials without using a stirring tool by providing plural hot water supply pipes, pouring the hot water to the bottom part and side part of a cup with geat force and stirring the hot water and raw materials. CONSTITUTION:The hot water flows from a hot water tank 6 down to a pressurizing tank 29 and pressurizing air is supplied from an air pump 28 which is a pressurizing means. In the tank 6, the hot water is pressurized to a rated value, which is determined by a check valve 33, and sent from an opening part 32 to a cup 3 against the check valve 33. In the cup 3, mixing liquid is made by raw materials 8 and the pressurized hot water. The hot water goes to be a stream, which rises up from the bottom part of the cup 3 along a side wall through a hot water supply pipe 34A, and after that, the stream is rotated along the side wall of the cup 3 through a hot water supply pipe 34B. By these two streams, since the raw materials 8 are dissolved into the hot water with being stirred, it is not necessary to put the stirring tool into the mixing liquid of the cup 3. Then, sanitary cooking can be executed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to self-selling in which cooked food is sold 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 supply device into the same mixing bowl 5.
1 to A3 are dissolved in warm water B, and the melted liquid C is poured into cup 3 of cup station 1. When the pouring is finished, one sales operation is completed. 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 step a, first, as shown in FIG. 8(a), the raw material 8 is charged into the cup 3, and then, as shown in FIG. 8(b), hot water Pour. At this time, hot water is flowing down from the hot water tank 6. Furthermore, the eighth
As shown in Figure (C), a screw 10 is inserted into the liquid mixture 9 in the cup 3 and stirred to sufficiently dissolve the raw material 8.

Then, pull out the inserted screw 10 as shown in Figure 8 (
As shown in d), the raw material 8 is a product in which hot water Ct: is melted. In this case, since the screw 10 stirs inside the cup 3, it is arranged with the mixing ball 5! 7 is not necessary.

Problems to be Solved by the Invention The vending machine that performs the cooking shown in FIG. 8 does not require the mixing pole 5 and piping 7, so it is more sanitary than the vending machine shown in FIG. , a screw 10 is placed in a mixture 9 of hot water C and raw material 8 poured into a cup 3.
Because 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 any equipment into the mixture.

Means for Solving the Problems The cup-type vending machine of the present invention includes a first hot water supply pipe for vigorously injecting hot water into the bottom of the cup or the vicinity of the bottom of the cup into which raw materials are input, and a first water supply pipe that runs along the side wall of the cup. A second hot water supply pipe is also provided to forcefully inject hot water, and the raw material is dissolved while being stirred with the hot water injected from the first and second hot water pipes.

According to this configuration, hot water injected from the first hot water supply pipe flows upward from the bottom of the cup along the side wall of the cup, and hot water injected from the second hot water supply pipe rotates along the side wall of the cup. It becomes a flow.

The raw materials in the cup are dissolved into the hot water while being stirred by the two streams mentioned above.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 6. 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 the part that performs the simple ig1 process of dissolving raw materials with hot water and discharging them, this part also uses a filter to filter the mixture of raw materials and hot water.
An extraction filtration device 11 is provided for cooking and discharging the 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 move up and down.
A band-shaped filter 15 pulled out from the wrapping body 14 is hung between the filtrate receiver 13 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 is pressed.
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 gradient 21.
2, and the mixed liquid 23 of coffee powder and hot water C is held at an upper level of 18 yen. In this state, open the valve body 22 and let the mixed liquid 23 flow down into the lower chamber 19.
Pressurized air at atmospheric temperature is blown in from the air supply port 24 in a controlled manner so that the pressurized air does not leak from the air supply port 24. In the state shown in FIG. 3, the mixed liquid 23 in the lower chamber 19 is
5, the extraction chamber side 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 downstream passage 2 together with pressurized air.
5 and is pushed out by pressurized air and discharged into the cup 3.

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 injected into the cup 3 of the input stream of the raw material 8 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 first and second hot water supply pipes 34A and 34B extending to the cup 3 via a check valve 33. Open the valve body 31 of the upper opening 30 to close the pressurized tank 2.
Hot water C, which is used for one cooking, flows down into the hot water tank 9 from the hot water tank 6 via the third electromagnetic valve 35, after which the valve body 31 is held in a closed state. Pressurized air is fed into the opening 36 of the pressurized tank 29 from the air pump 28 via a fourth electromagnetic 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. Until this internal pressure rises to a specified value determined by the check valve 33, the hot water supply pipe 34A.

Hot water C is not poured into cup 3 from 343.

When the internal pressure of the pressurized tank 29 exceeds the specified value, pressurized hot water C is forcefully injected into the cup 3 from the supply 1'g 34A, 343, and the raw material 8 in the cup 3 and the injected hot water C are mixed. A mixed liquid 9 is formed, and the mixed liquid 9 is stirred by the force of the injected hot water C, and the raw material 8 is dissolved in the warm water C.

Here, the first and second hot water supply pipes 34A, 343 are oriented in different directions as shown in FIGS. 1 and 4. The first hot water supply pipe 34A injects hot water toward the bottom 3A of the cup 3, thereby creating a flow I in the cup 3 that rises from the bottom 3A to the side wall B of the cup. The second hot water supply pipe 343 injects hot water along the side wall 3B of the cup 3, and a rotating flow (2) is generated inside the cup 3 along the side wall 3B. The raw material 8 in the cup 3 flows through this flow 1. Incorporate the solution while thoroughly stirring with II.

Note that only the first hot water supply pipe 34A is connected to the second hot water supply pipe 34B@
If it is not provided, the raw material 8 in the cup 3 is already
The mixture is stirred and sufficiently dissolved, but the mixture is noticeably bubbling. On the other hand, in the case of only the second hot water supply pipe 34B, it is good in that there is no bubbling as described above, but the raw material 8 tends to remain undissolved in the center of the bottom portion 3A. In this embodiment, since hot water is injected vigorously through the first and second hot water supply pipes 34A and 34B, a good cooking condition is achieved with no foaming and the ingredients in the center of the bottom being completely stirred. Waited.

In this way, the liquid mixture 9 in the cup 3 is stirred by the pressure feeding energy of the injection of the hot water C without inserting a stirring device such as the screw 10. It is hygienic because it can be

Assuming that the cup used here is a 7-ounce cup, the robot hand 41C moves to a position below the cup dispenser 39A as shown in FIGS. 5 and 6, and the robot hand 41C takes the dispensed cup 3. Uke is taken. Next, pulse motor M1.
Apply to M2. When the application of this driving pulse ends,
Operate the dispensing motor of raw material tank 4A for the specified time,
Raw material A1 is put into the cup 3 held by the robot hand 41C. When the dispensing operation of raw material A1 is completed, raw material A such as cream and sugar is prepared based on the cooking data.
2. When A3 is required for cooking, the robot hand 41G is moved to the position for receiving the discharged raw material of the raw material 14B and the position for receiving the discharged raw material of the original slope bridge 4C, and when the robot hand 41C arrives at the lower position of the raw material tank 4B. The dispensing motor of the raw material tank 4B is operated, and when the raw material a1 arrives at the lower position of the raw material 14C, 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 in the raw material tanks 48 to 4C is explained as an example, but the raw material tanks 4
It may pass through one or two raw material input positions A to 4C.

When all the ingredients necessary for cooking have been added, the cup 3 is transferred from the current position of the robot hand 41G to the cup station 1, and the cup 3 into which the ingredients have been added is transferred.
is delivered to cup station 1.

In the above embodiment, hot water C was injected into the cup 3 from the supply PIA pipes 34A and 34B at the cup station 1, but before reaching the cup station 1, for example, the
