operates, the power to the relay R6 is cut off, the pendant motor VM operates, and at the same time the self-propelled switch S is activated to make the movement 14 reciprocate once and then stop. By switching the running switch SvM, the self-holding of the relay R3 is released, and the relay R6 energizes the restoring coil 52RL to restore the stepping relay 52 to its original state. Furthermore, relay R7 is operated by the second switch R3-2 of relay R3, and cam timer motor TM, relay R8, motor motor Ms
are operated respectively. The motor Ms opens the bottom door 18 of the heat insulating box 3 and is driven by its own self-propelled switch SMs. However, after a certain period of time, the timer cam switch T6
After being temporarily stopped, the door 18 is closed again and the door 18 is closed. During this opening, the product is released from the release row 7. Relay R8 includes a fall detection switch Rsw, a manual switch S, and its own first switch R6-,
flows to form self-holding, and at the same time the second switch R8
-2 causes the solenoid RS that closes the coin input row 5 to operate. Also, Cam Timer TM is Cam Timer Switch T.
, the power is applied until the selling operation is completed. Then, the third switch R of the relay R is activated by the cam timer switch L.
, -3 is disconnected, the solenoid continues to operate. After the motor M8 is driven by the second switch R7-2 of the relay R7 and the cam timer switch T4 by the relay R7, the rear door 25 is opened/closed once by its own running switch SMB. When this opening coincides with the opening of the bottom door 18 and the release of the product from column b, the fall detection switch Rs.
By operating w, it is urged into the heating chamber 23 and stored. As mentioned above, when the fall detection switch Rsw operates, the self-holding of the IJ relay R8 is released, the relay R9 operates, and the cam-timer switch T? A self-holding circuit for relay R9 is formed by this. By releasing relay R8, solenoid C
The RS is deactivated and coins can be accepted. At the same time, when the rear door 25 of the heating chamber 23 is closed, the switches RDS, , RDS2, RDS3, and RDS4 are closed, so the second switch R9-2 of the relay R2,

It is heated for a certain period of time via DS3 and RDS4. At the time when this heating is completed, the cam timer switch T5 is activated, the motor MF is activated, and the self-propelled switch SMF is operated once to open and close the product to scrape off the product and send it to the opening/closing lid 45. When this feeding is completed, the cam timer motor T3 is turned off, the solenoid ls is opened, and the opening/closing lid 45 is unlocked. In this way, the heating sale operation of the product is completed. If the product is not released from the heat insulating box 3, the relay R9 does not operate, so the heating device 56 does not work, and the solenoid CRS is energized to the relay R8, causing no brim, and subsequent coin insertion is rejected. be. The release means that sales will be discontinued unless the cause of the product not falling is removed and relay R8 is released using manual switch S. Further, when the temperature of the heat insulating box body 3 rises, the thermostat R,. The solenoid CRS operates and refuses to accept the coin. Furthermore, the same applies when the opening/closing lid 45 is closed before inserting coins. The loading of the product into the heating chamber 23 is performed using the rear door 25 and the auxiliary door 38. When the rear door 25 is opened, the guide pieces 3 on both sides of the guide plate 37
7', 37'' to prevent the product from falling, and the auxiliary door 38 also opens in cooperation with the grooves 39, 39'.
The tips of the guide plate 37 and the auxiliary door 38 are smoothly guided onto the auxiliary door 38 to eliminate the difference in level due to the uneven portion. At this time, the article is dropped from the auxiliary door 38 into the scraping frame 35. That is, since it is located above the inclined surface 36 which is the rear end of the scraping frame 35, it can be reliably guided into the scraping frame 35. Further, when the product is not guided into the scraping frame 35 with the rear door 25 open, the product can be guided into the scraping frame 35 by the closing operation of the rear door 25. This is because the angle of inclination of the auxiliary door 38 and the rear door 25 increases, causing them to fall under their own weight. Also, at this time, the sea bream supporting side of the auxiliary door 38 is positioned above the slope 36, which is the rear end of the scraping frame 35, as described above, so that the sea bream can be reliably guided into the scraping frame 35. Then, the product is sent out from the front opening □ by the frame 35 of the front door 24, which is opened after the heating is finished, but at this time, the rear end of the frame 35 is connected to the guide rails 33, 33'.
The rear end surface of the frame 35 rotates in order to project the protruding pins 34, 34' and move horizontally.
Since the inclined surface 36 is formed so as to be perpendicular to the bottom surface of the chamber when the heating chamber 2 is opened to the maximum angle, the heating chamber 2
This prevents the product from rolling to the bottom of the door, causing the product to be lost or not being sold when the front door is opened. Furthermore, since the bottom surface is also uneven, the product can be scraped off smoothly with less surface contact with the bottom surface, and the motors MF and MB that drive each door 24 and 25 can be rotated in a fixed direction. Since there is no need to change the opening angle of the door when loading and unloading the product, control can be easily performed.
In the above embodiment, the coin slot is locked, but it may be configured so that it does not accept coins.

As is clear from the above embodiments, the product heating vending machine of the present invention includes an insulating box body provided with a discharge port for cooling and storing sales products and having an opening/closing bottom door in the vending machine main body; A rear door is provided at the lower part of the insulating box body and is provided at the lower rear portion of the insulating box body to catch and store the product by moving into the fall trajectory of the product discharged from the discharge port of the insulating box body, and the heated product is provided at the front side. a heating chamber equipped with a front door for sending out the heating chamber; a door having a basket-shaped opening/closing lid provided on the front side of the main body and located on the same plane as or below the delivery port of the heating chamber;
A frame body attached to the front door scrapes out the product inside in conjunction with the opening operation of the front door of the heating chamber, and a frame body located within the heating chamber that allows the product to fall into the frame body when the rear door is opened. One of the auxiliary doors is pivotally supported above the rear of the frame where the front door is located when opened, and the other is slidably attached to the groove of the rear door. Since the front door is used for sending out products, the degree of opening of each door can be kept constant, making it easy to control the opening of the doors.

Further, a frame body is provided on the front door, and an auxiliary door is provided that opens and closes in conjunction with the rear door in order to scrape out products, and a ball, which serves as a rolling fulcrum for this auxiliary door, is positioned above the rear end of the frame body. Since the bottle reliably guides the product into the frame, it can be scraped out without fail.
