[Detailed Description of the Invention] - Field of Commercial Use The present invention cools articles, and! ! 'i7j+a Refrigerated vending machine that can be stored even if it is used for a single use.
l: This relates to an ia storage switching type storage vehicle.

The configuration of the conventional example and its problems Conventionally, this scale has been known as refrigeration /, 'Diary operation] jJ exchange type storage 1.11 (sex, self-selling 4 bales - ; role) Therefore, this slave, A's automatic, provisional sale 1. The cane will be enjoyed in 4 thoughts from Figure 11 to Figure 31.In addition, in the text, what is the power of refrigeration (11 cold, /1111)?11:a It is called.

1 is a small vending machine consisting of an insulated box body 2, and these 4

3b is provided with commercial crystals fd, flD]4a, and 4b, respectively.

Since the product shelves 4a and 4b may be columns of the surpe/tights type, a detailed explanation will be omitted.

The product storage chambers 3a and 3b are equipped with cooling evaporators 5a and 5b, respectively, and a heater 6a.

has been done. The evaporators 5a, 51) arranged in each chamber 3a, 3'b are connected in series to each other to evaporate the bales H,'
1h dynamic compressor 8, condenser 9, flow divider 10. The first capillary tube 11a, the evaporator 5a, and the evaporator 5b are connected in this order. It's ugly, the evaporator 5
A second capillary tube 11b is provided to bypass the first capillary tube 11a, and a refrigerant open side 1#12, which is a reverse-acting type valve 1e, is disposed in the artificial part of the first capillary tube 11a. This refrigerant control valve 12 is a type of valve that closes when it is running and opens when it is not running. are opened and closed by manually operating a changeover switch 15.

Reference numeral 13 is a fan motor that radiates heat from the electric motor E @ 6 Krona 8 + Contenza 9.

Next, the circuit will be explained.

The blowing fans 7a and 7b are each connected to a power source.

However, the fan motor 13 and the commercial compressor 8 are connected to the power source via a refrigerating thermostat 14 and a changeover switch 16.

And 15 is 4i, 3 a's cold t1111 effect i>
This is a switch for i and h, and switch 15 is set to 0N-j#
is passed to the heater 6a of the right ventricle and the refrigerant control valve 12.

The heating heater 6b is connected to the -C4 terminal via the other switch 26.

In the above structure (fζ), if we explain the operation one time, if the substitute storage chambers 3a and 3b are both cooling type, switch 1
5 is turned off to open the refrigerant 1131J valve 12 and the heater 6a. -Also, by using the switch 16, the dynamic pressure Yamiiso 8 and the gamma motor 13 are connected in six lines.

This causes the cooling system to move, and the flow of the refrigerant is such that the liquid refrigerant condensed by the condenser flows into the flow divider 10, where the gas and liquid are separated. Liquid refrigerant flows into the first capillary tube 11a (Ill) connected to the first capillary tube 11b, and gaseous refrigerant flows into the second capillary tube 11b side. Since the amount of refrigerant flowing into the second capillary tube 11b is extremely small compared to the first capillary tube 11a, the refrigerant flows through the bf path as shown by the solid arrow.The refrigerant then sequentially flows through the evaporators sa and sb. As a result, both product storage chambers 3a and 3b are cooled until the cold thermostat 14 is turned off.
In the case of "a to vortex, to cold storage to 3b" (d2, by turning on the switch 15, the refrigerant 11rlJ El
lj2 and the heater 6a. However, the collar strap 16 is the same as the above-mentioned case.

As a result, the flow of the refrigerant is directed from the molecular AC unit 10 to the first capillary tube 11a It! The refrigerant i:ilj is blocked by the valve 12.The refrigerant i:ilj is blocked by the valve 12.The refrigerant i:ilj is blocked by the valve 12. The refrigerant circuit will cool only the product storage chamber 3b), and the J operation will be performed.

The other product storage chamber 3a is heated by a heater 6a.
It is said to be 1□-51 Unko.

Then, both the storage rooms 3a and 3b are opened.
In the case of "1", the VJ support switch 16 is turned on to the heating heater 6.
b (+, !II circuit 14 is turned on and the switch 15 is turned on to stop the electric pressure ?i1 and 8, and the heating heaters 6a and 6b are used to heat both 1 and M product storage chambers 3a and 3b.

11i In case of burial, in order to perform gas-liquid separation of the refrigerant using the dL divider 10, the internal volume of the d1 flow divider 10 is made large and the refrigerant flow rate within the flow divider 10 is sufficiently reduced. However, sufficient gas-liquid separation could not be achieved.

Therefore, it was necessary to enclose the flow divider 10 in a non-flat position.During the cold-7j:a operation, liquid refrigerant force R1 is generated in the flow divider 10, so the settings of each chamber 3a, 3b are changed. However, in the case of cold-cold and cold-hot, the refrigerant J-1;Z is different.
It becomes +1. However, if the flow divider 10 is made smaller, the second capillary tube 11b'lI is used during cold-cold operation.
! To II, the liquid refrigerant becomes 01ε easier for people to cool,
1' system becomes unstable. Moreover,
Cold 7:n11 Luck 1 version condition occurs from late autumn to early spring when outside air 7□1111 is low lj;+Jノ! Jl, and at this time, the cooling L-J (condenser heat dissipation in the cooling cycle becomes larger than that in the original), so the supercooling of the cold brew inside the condenser 9 progresses.For this reason,
Since the phenomenon of liquid refrigerant percolating inside the container/container/container 9 occurs, the phenomenon of refrigerant shortage occurs even more when the cooling/crystal is stopped and the cooling system becomes insufficient. The disadvantage of being cheap was fi'.

Purpose of the Invention The present invention eliminates the above-mentioned drawbacks and provides a cold-7:11 (continuous)
The purpose of this invention is to obtain a cooling system that ensures stable cooling performance and heating performance during one rotation.

Structure of the Invention In order to achieve the objective 1, the area around the fan motor for heat dissipation of the capacitor of the cooling l/IJ system was developed. By controlling the number in stages according to changes in outside temperature (C control),
This prevents the phenomenon of excess or deficiency of the appropriate IE enclosed cold IAL'Wr'' of the cooling system caused by fluctuations in the cooling load meter due to fluctuations in outside temperature, thereby making the cooling system more stable.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG.
The configuration of the cooling system is the same as the conventional one, and a detailed explanation will be omitted, and the IR circuit, which is different, will be described.

It is being read. The common end of the tap changeover switch 17 is connected to the cold thermostat 14 and the power supply via the changeover switch 16.

In such a thing, each chamber 3a, 3b is 7! n! −
A case of cold operation will be described, but since the flow of the refrigerant is the same as that explained in the conventional example, a detailed explanation will be omitted. Outside air 7Ai! is 10° C. or more, the outside temperature thermostat 18 is closed, the coil 17C is energized, the contact point of the tap changeover switch 17 becomes the terminal 17a, the fan motor 19 is connected to the high speed side terminal 19a, and the 7 am motor Rotation number 19 is high speed. For this reason, capacitor 9Q
Add heat dissipation to make the normal cooling system quadruple.

When the outside temperature is low/11iA below 10℃,
Outside air l+'o! Thermostat 18 is opened and coil 1
7c is turned off, and the contact point of the tap changeover switch 17 is switched to the terminal 17b. At this time, only one fan motor is connected to the low speed 1011 terminal 19bK, so the fan motor 19 rotates at a low speed. For this reason, the heat dissipation surface of the condenser 9 is lowered and supercooling does not occur, so it becomes difficult for the refrigerant to flow inside the condenser 9. This makes the system Since more refrigerant is required, a system can be obtained in which the refrigerant does not stop flowing even when the outside air is low at 7Aa.

As described above, by detecting fluctuations in outside air d1^ by outside air t111t thermostat 18, and tilting the rotation speed of fan motor 13 to high speed rotation when high outside air IM, and to low speed rotation when low outside air 7fi+j. It is possible to control the heat dissipation power of the condenser 9 in the cooling cycle, and to prevent liquid refrigerant from accumulating due to overcooling of the condenser 9 at low outside temperatures. By reducing the speed by 1 inch and lowering the rotation speed,
It is possible to reduce the amount of manpower required, and it is also possible to save energy and energy. This ensures stable cooling and heating performance regardless of outside temperature fluctuations.
5.16 rijurutake, to 3a, 3b are cold-cold,
41 combinations of hot-cold, warm-/1″1□1 can be obtained, and one vending machine can sell cold items and hot items at the same time.

11 degrees Celsius, the invention is not limited to 1. Similar effects can be obtained not only in vending machines but also in any cooling system that is equipped with two evaporators and controls the inflow of refrigerant into either one of the evaporators.

Effects of the Invention As is clear from the above embodiments, the present invention prevents supercooled liquid refrigerant from accumulating in the condenser by occasionally rotating the fan motor 'C1ki1fii' of the condenser of the cooling system at a low speed. It is possible to prevent excess or deficiency of refrigerant due to load fluctuations caused by outside air fluctuations, resulting in more stable cooling, lj, and addition! 1i't'MLY1hikaryo4J Ranoshiru.
