Description

vending machine

The present invention relates to a vending machine, and more particularly, to a vending machine that improves the heating efficiency by improving the structure of the hot water supply device.

In general, a vending machine is a mechanical device that automatically delivers goods to an exit when a predetermined amount is input. Among them, a hot water supply device is provided to heat water so that hot water can be supplied from a vending machine selling coffee or tea. . The internal structure of this hot water supply device is as shown in FIG.

As shown in the drawing, the hot water supply device 1 is a container in which water is heated and stored, and includes a hot water container 2, which communicates with a water tank not shown in the hot water container 2. A supply pipe 3 for supplying water and a discharge pipe 3 connected to a mixer (not shown) for mixing materials are provided. On each side of the supply pipe 3 and the discharge pipe 4, a supply valve 3a and a discharge valve 4a for controlling the inflow and outflow of water are provided, respectively. In addition, a heater 5 for generating heat by applying power to the lower part of the hot water tank 2 is installed, and a float 6 that moves up and down in accordance with the water level stored in the hot water tank 2 is installed. Then, as the float 6 moves up and down, a switching section 7 is provided which selectively contacts the top contact portion of the flop 6 to control the opening and closing of the supply valve 3a.

The conventional hot water supply device configured as described above opens the supply valve 3a by the operation of the switching unit 7 when the float 6 inside the hot water tank 2 descends below a predetermined position. Water flows into the hot water tank 2 through the supply pipe 3 through the opening of the supply valve 3a, and as the water level rises, the float 6 rises until the proper water level is reached. The contact valve is reached to shut off the supply valve 3a. Then, when water is supplied to the hot water tank 2, the heater 2 is operated so that the heat of the heater 5 is directly transferred to the water and heated, and the water in the hot water tank 2 is heated by the convection of water.

However, due to the scale generated on the surface of the heater by long-term use of the heater in the hot water supply device of the conventional vending machine, not only is it unsanitary, but also a problem that the heating efficiency is lowered. In other words, since the heater is directly heated to heat water, a scale, which is a piece of heated oxide, is generated on the heater surface, and this scale may be contained in the water discharged away from the heater. In addition, when the scale is attached to the heater surface, the heat conduction due to the scale falls, causing a problem that the heating time of the water is delayed. In addition, this causes a problem that causes a loss of power.

It is an object of the present invention to provide a vending machine that generates high temperature steam and uses the same to indirectly heat water in a hot water supply device.

In order to achieve the object of the present invention, the present invention is provided in a vending machine provided with a bucket for storing water, a hot water tank for heating and storing the water supplied thereto through a supply pipe from the bucket, Steam generating means for generating steam so that the supplied water is indirectly heated by the steam is characterized in that it is provided.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment according to the present invention in detail.

Figure 2 is a front view showing the internal structure of the vending machine according to the present invention, as shown in this, a cabinet 100 forming a body is provided, the upper portion in the cabinet 100 and the water reservoir 110 for storing water; A raw material container 120 for storing coffee and tea is installed. The lower portion of the raw material container 120 is provided with a mixer 130 for mixing a raw material and water to make a beverage, such as coffee, is provided with a cup withdrawal unit 140 is discharged and seated so that the mixed drink is fresh water. In addition, one side in the cabinet 100 is provided with a hot water supply device 200 for heating and storing the water supplied from the bucket 110 when a warm drink is required.

This hot water supply device 200 will be described with reference to FIG. The hot water supply device 200 is provided with a hot water tank 230 in which predetermined hot water is heated and stored, and the hot water tank 230 has a supply pipe 210 and a discharge pipe 220 connected to the water tank 100 and the mixer 130, respectively. ) Is installed. In addition, a supply valve 211 and a discharge valve 221 are respectively provided between the supply pipe 210 and the hot water container 230, the discharge pipe 220, and the hot water container 230 to regulate the inflow and outflow of water. In addition, the float 150 which is raised and lowered according to the level of the inside of the hot water tank 230 and the contact of the float 150 in order to adjust the supply valve 211 according to the water level inside the hot water tank 230. The switching unit 160 for opening and closing the supply valve 211 is provided with different portions.

On the other hand, as a characteristic part of the present invention, the steam generating means is provided to indirectly heat the water introduced into the hot water tank 230 using steam.

First, the steam generating means is provided with a conventional heat conducting member 242 in which a predetermined steam generating space 243 in which steam is generated is formed. In addition, an inner case 240 and an outer case 241 made of aluminum are deposited on the inner and outer circumferential surfaces of the heat conductive member 242. A branch pipe 260 branched from the supply pipe 210 and connected to the steam generating space 243 is provided to supply predetermined water to the steam generating space 243 surrounded by the cases 240 and 241. At the end of the branch pipe 260, a pump 250 may be installed in which water in the branch pipe 260 may be selectively pumped into the steam generating space 243, and the pump 250 may be provided in the steam generating space 243. A spiral type dispersion part 270 is positioned so that water discharged through the gas is dispersed. The heater 280 is built in the heat conducting member 242 so that steam is generated as the water dispersed in this way, and the generated steam is discharged to the hot water tank 230 to generate a steam space for heating the water inside the hot water tank 230. A connection pipe 290 for communicating the inside of the 243 and the hot water tank 230 is provided. In addition, a pressure control valve 291 is installed at one side of the connection pipe 290 to control the discharge of steam and to generate a high temperature steam by adjusting the pressure of the steam generating space 243. The pressure regulating valve 291 can generate steam of about 180 ° C. Then, the heat conduction fin 244 is installed on the heat conduction member 242 so that the hot water of the hot water tank 230 heated by the steam can maintain a predetermined temperature.

When water is supplied to the hot water tank 230 in the hot water supply device 200 of the vending machine according to the present invention configured as described above is heated by the steam generating means. First, when water in the branch pipe 260 is supplied from the steam generating means to the steam generating space 243 by the pump, the water dispersed while being dispersed by the dispersing unit 270 comes into contact with the inner case 240 and the heater 280. Heat is transferred through the heat conducting member 242 to become steam. The steam is generated at a high temperature of 180 ℃ due to the pressure control valve 291, when a predetermined steam is generated steam is discharged to the hot water tank 230 through the connection pipe 290, the water inside the hot water tank 230 Heat it. Thus, by indirectly heating the water inside the hot water tank 230 through the steam it can be prevented from generating impurities. In addition, the water heated by the heat conductive fins 244 may maintain a predetermined temperature.

In the vending machine according to the present invention using the high temperature steam generated by the steam generating means to heat the water inside the hot water tank.

Therefore, since water is indirectly heated using steam, there is an advantage that the clean water can be supplied by preventing impurities from being generated.

In addition, by suppressing the generation of impurities, there is an advantage that the heating time is delayed or the power loss is reduced.
