が拡大された。The above-mentioned vending machine has three compartments that can be used as a heating compartment (H) or a cooling compartment (20) depending on whether the product is being sold as a hot product or a cold product. Initially, the above vending machine did not have heater IIL and thermostat 12L installed in the left ventricle, and the usage mode of the middle chamber M1 and right ventricle N was set to C-C-C or C-H-C. Right ventricle N is dedicated for cooling, middle ventricle M
It was used for cooling or heating depending on the product. Cooling of the left ventricle is controlled by opening and closing the solenoid valve 8L, while cooling of the right ventricle N is performed by directly controlling the operation of the compressor 4. The heater IIL and thermostat 12L were also installed in the left ventricle so that products could be sold in more variety. As a result, the usage mode of the three chambers in the refrigerator is changed from the conventional C-C-C.
and C-H-C in two ways, plus H-H-C and H-C-
It became possible to use C in two ways, expanding the sales area for the product.

不具合が生じていた。By the way, in a conventional vending machine where the three compartments can be used in four different modes, the thermostat (12)
Since the operation of the compressor 4 is controlled by N, the usage mode H-H-C or H- in which the left ventricle is used for hot products is selected.
When changing the usage mode from C-C to C-C-C or C-H-C in which the left ventricle is used for cold products, the left ventricle may take a long time to cool or is not cooled sufficiently. was occurring.

When used as a cooling chamber, the shutter 11 is opened and cold air cooled by the evaporator 7N is sent through the ventilation hole 12. Also, when using it as a heating chamber, shutter 1
1 is closed and heated by the heater 11M. Therefore, the three chambers in the warehouse, left ventricle L, middle chamber M, and right ventricle N, are c-c-c.
, c-H-C, H-H-C, and H-C-C. Cooling of the right ventricle N is controlled by opening and closing a solenoid valve 9N by a thermostand 8N that detects the cooling temperature in the room. Furthermore, the compressor 4 continues to operate when one of the solenoid valves 9L and 9N is open, and stops only when both solenoid valves close. Therefore, even when the left chamber is switched from the heating chamber to the cooling chamber, the compressor 4 continues to operate by opening the solenoid valve 9L depending on the temperature detected by the thermostat 8L, so it is sufficiently cooled and in a short time. It is cooled to a predetermined cold storage temperature.

ることができる。According to this invention, the vending machine has an interior divided into three chambers, a left chamber, a middle chamber, and a right chamber. It consists of one compressor that circulates and supplies air, and a ventilation hole that opens in the partition wall between the right ventricle and the middle chamber and is equipped with a shutter that can be opened and closed. In this internal cooling device for a vending machine, which is selectively used as a cooling chamber, thermostats are installed in each of the left and right chambers to detect the cooling temperature in the room, and the thermostats are activated via each of the thermostats. A solenoid valve is installed in each of the branch pipes to the left and right chambers of the refrigerant piping that guides the refrigerant from the compressor, so that the three chambers are C-C-C, C-C-C, -H-C, H-H-C,
In addition to being used in four modes: H-C-C and H-C-C, it also takes a long time to cool down, which previously occurred when the right chamber was switched from heating chamber H to cooling chamber C. It is possible to solve the problem of not being able to sell various products, and to make each of the three rooms extremely suitable for the sale of various products.
