Description

Automatic vending machine for heating food}

The present invention relates to a heated food vending machine, and more particularly, to uniform heating and freshness continuously in a state of storing foods such as hot bars, hot dogs, sausages, and the like sealed with synthetic vinyl paper (PE resin). The present invention relates to a heated food vending machine, which is capable of maintaining long-term storage and ensuring hygiene, but does not stick to each other in a storage room and makes dropping easier.

In general, the vending machine is a system that sells various items unattended. Among them, the vending machine is a vending machine that sells beverage products packed in cans and coffee in disposable cups. Automatic vending machines developed for heating foods to meet the requirements of the burgers and noodle vending machines.

In other words, the conventional vending machine developed for foods that can be eaten just by heating as it is packed in a vending machine is a "burger vending machine with a microwave oven" of Korean Utility Model Publication No. 1985-4211. There is a "hamburger vending machine" of Patent Publication No. 2001-65500.

However, among the above-mentioned vending machines, the utility model of the former has to have a costly microwave oven for heating a hamburger. In addition, the hamburgers loaded in the storage compartment are easily damaged and cold in the summer when the outside weather is hot, because only one hamburger being drawn out is instantaneously heated by using the high frequency of the microwave. In winter there is a problem that the hamburger in the storage room is frozen and taste is reduced.

In addition, the latter invention patent has a method of keeping the hamburger storage room wrapped with the thermal insulation material in a predetermined temperature range by using hot water in the boiler room heated by the heating means such as a heater. This is an indirect heating method using hot water, there is a lot of heat loss, there is a problem that a pipe for hot water circulation, etc. must be installed in a complex.

In addition, since the former and the latter vending machines form the compartments of the storage compartment vertically, foods stored in these vertical storage compartments are naturally stacked vertically while the packaging papers are in contact with each other. .

By the way, when hot food is heated in a state in which vertically laminated foods such as hot bars, hot dogs, sausages, etc. are stacked so that the plastic wrappers are in contact with each other, the plastic wrappers stick to each other and do not fall well, so there is a problem in that individual drops are not easily dropped. Foods such as these hot bars are difficult to keep fresh.

Therefore, in the past, a vending machine for selling burgers wrapped with paper is developed in various ways, but food vending machines such as hot bars, hot dogs, sausages, etc. sealed with synthetic vinyl paper have not been developed.

Therefore, the present invention was developed to solve the above-mentioned conventional problems, an object of the present invention is to maintain the freshness when storing foods such as hot bars, hot dogs, sausages and the like sealed in synthetic vinyl paper It is to provide a heated food vending machine that can be stored for a long time, and that the wrapping papers of the items placed in the storage room can be easily dropped without sticking to each other.

An object of the present invention is a storage room which is installed in the form of a box inside the main body in the state in which the inner door is installed; A ceramic rod heater installed at the bottom of the storage chamber; A plurality of support plates which are gradually stacked toward the top while being continuously stacked horizontally to form a multilayer on the rod heater; A coiled spiral shaft rotating at a low speed by a geared motor on the support plate; Packaged products such as hot bars sandwiched between the respective winding portions of the spiral shaft in a packaged state; A detection unit installed at the end of the support plate to detect the presence or absence of a product; Ultraviolet sterilization lamps installed on the inner side of the inner door of the storage chamber to sterilize the storage chamber; It is achieved by configuring a heated food vending machine with a circulation fan that circulates the heat of the rod heater applied to the upper part of the storage compartment inside the storage compartment.

In the configuration of the present invention shown in the front door 110 of the main body 100, the banknote inlet 111 and coin inlet 112, the selection button 113, the outlet 114, coin return port 115, specimen The display unit 116 and the advertisement unit 117 are provided in the same manner as a conventional general vending machine.

The present invention forms a box-shaped storage chamber 121 in which the inner door 120 is installed at the front side in a state in which one side is opened in the main body 100, but most of the heat is formed at the bottom of the storage chamber 121. The rod heater 130 coated with ceramics is installed to operate, and the support plate 140 formed with a plurality of through holes 141 is installed at a predetermined interval so as to be horizontally stacked on the rod heater 130, but at one end of the storage chamber. It is fixed to the side wall of 121, characterized in that the drop guide path 142 of a predetermined interval is formed between the other end of the base plate 140 and one side wall 101 of the main body 100.

In addition, the upper surface of each support plate 140 is installed to be selected and driven by the selection button 113, the coil-shaped spiral shaft 150 is rotated separately by the geared motor 151, the spiral shaft 150 Between each of the winding parts of the product 200, which is individually wrapped, such as hot bar sandwiched between the support plate 140, characterized in that placed on.

At this time, the length of the laminated support plate 140 and the spiral shaft 150 is formed in an inverted staircase in which the length gradually shortens from the top to the bottom as shown in FIG. 4 and is spaced from one side wall 101 of the main body 100. It is preferable to form it gradually wider toward this lower part, and it may be shortened gradually by making a pair as shown in FIG.

In addition, a micro switch 160 is installed at the end of the support plate 140 as a sensing unit for detecting the presence or absence of the product 200 as shown in FIG. 5, and when the product 200 is on the support plate 140, the micro When the operation piece 161 of the switch 160 is pressed and the product 200 is not exhausted, the operation piece 161 is raised to indicate that there is no product. In addition, an ultraviolet sterilization lamp 170 and a circulation fan 180 are installed on an inner surface of the inner door 120 of the storage chamber 121.

In the drawing, reference numeral 131 is a temperature sensor for preventing the rod heater from being overheated above a set temperature, and 143 is installed at the bottom of the drop guide path 142 to guide the dropped product to the outlet 114. It is a guide plate, and each component is controlled by a chordroll unit (not shown in the drawing) installed on the circuit board.

According to the present invention formed as described above, a product of one of the storage compartments connected to the selection button of the plurality of storage compartments is inserted through the guide plate 143 by inserting the corresponding amount through the banknote inlet and the coin inlet installed in the front door of the main body 100. Falling to the outlet can be taken out, and if there is any money left to be returned to the coin return coin, which is the same as a normal vending machine.

In the present invention, since the storage chamber inside the main body 100 is in the form of a box in which all of the remaining portions except the one-side drop guide path 142 are blocked, the high heat generated from the rod heater 130 installed at the bottom thereof is mostly in the upper portion. The plurality of stacked support plates 140 are positioned, and the rod heater 130 is coated with ceramics, thereby heating a product such as a hot bar, which is individually packaged while emitting a large amount of far infrared rays with high heat.

In addition, the circulation fan 180 installed on the inner surface of the inner door 120 operates under the direction of the control unit when the heat generated by the rod heater 130 is detected to be higher than a set temperature. The rod heater 130 is operated. Since the even heat is circulated evenly in the inside of the storage compartment, the products such as the hot bar, which is placed on each support plate 140 and sandwiched between the winding portions of the spiral shaft 150, are all maintained in a uniformly heated state.

In addition, since the sterilization of the interior of the storage room is very good by the ultraviolet light of the germicidal light 170 installed on the inner side of the inner door 120 in the state that the heating of the product is maintained evenly, it is possible to ensure hygiene. Of course, the freshness of the product can be maintained for a long time.

In addition, the products such as the hot bar are sandwiched between the respective winding portions of the coil-type spiral shaft 150 in the individually packaged state as mentioned above, even if the adsorption force is generated on the surface of each wrapping paper due to the high heat of the applied heater. Since it does not stick to the support plate 140 can be moved horizontally smoothly, because of this, only one product of the line selected by the selection button is dropped into the guide plate 143 at the bottom of the drop guide 142 is discharged to the outlet.

At this time, the present invention is because the laminated base plate 140 and the spiral shaft 150 is formed at the upper end and the short one at the lower end, the drop guide path 142 naturally becomes wider than the top. Therefore, when the line selected as described above is the top line, the packaged product falling from the end of the base plate 140 may be prevented from coming into contact with the packaged products placed on the bottom base plate 140.

In addition, the operating piece 161 of the micro switch 160 installed at the end of each supporting plate 140 is pressed on the product when the products are on the upper surface, and the operating piece 161 immediately rises when all the products on the line are discharged. As there is no product on the front of the door, the user can use other selection buttons except the selection button on the line.

As described above, the present invention is to move the various heating foods (hot bars, hot dogs, sausages, etc.) that are individually wrapped in a synthetic vinyl wrapping paper to stick to each other when the heat is inserted into the winding portion of the spiral shaft so that they are separated from each other. The movement and fall of the smoothly, especially the length of the support plate and spiral shaft is formed in a reverse staircase gradually shorter from top to bottom, so that the wrapping paper of the falling product can be prevented from sticking to the bottom.

And when storing in the main compartment inside the main body, the heat of the rod heater is circulated by the circulation fan and kept in constant heat with uniform temperature without any change in temperature, and sterilization action such as sterilization is applied. It can be stored.
