[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vending machine that sells cold products that are cooled and kept cold and hot products that are heated and kept warm.
[0002]
[Prior art]
In recent years, with the diversification of sales products of vending machines, those capable of selling cold products and hot products are increasing, and multi-room hot and cold vending machines are disclosed in Japanese Patent Laid-Open No. 6-60262. It is disclosed.
[0003]
Hereinafter, the conventional vending machine will be described with reference to the drawings. FIG. 11 is a block diagram showing the configuration of a conventional vending machine. In the figure, 1 is a main body cabinet of a vending machine, 1A is a product storage room dedicated to cooling provided with a cooler 2A, and 1B is a product storage room used both for cooling and heating provided with a cooler 2B and a heater 3. The cooler 2A and the cooler 2B are individually supplied with a refrigerant from a common compressor 4. The cooler 2A directly passes through the solenoid valve, and the cooler 2B passes through the solenoid valve 5. Each is connected to the compressor 4 by a refrigerant pipe 6. This conventional example is characterized in that the cooler 2A is controlled so as not to overcool the commodity storage chamber 1A while having a simple configuration in which the solenoid valve is omitted. Note that a condenser, an expansion valve, and the like are omitted for simplicity.
[0004]
A room temperature sensor 7 and a room temperature sensor 8 each comprising a thermistor are installed in the product storage chamber 1A and the product storage chamber 1B, respectively, and the control unit 9 controls the compressor 4 and the electromagnetic valve 5 on and off based on these temperature signals. Here, an upper limit temperature and a lower limit temperature for ON / OFF control of the cooler 2A and the cooler 2B are input and stored in the control unit 9, and a switch 10 for switching between cooling and heating of the product storage chamber 1B is provided. When it is turned on, an energization circuit for the heater 3 is formed.
[0005]
The operation of the above configuration will be described. When the switch 10 is on the cooling side and both the product storage chamber 1A and the product storage chamber 1B are set to be cooled, the electromagnetic valve 5 is opened and the compressor 4 is operated. As a result, the refrigerant is supplied to both the cooler 2A and the cooler 2B, and the product storage chamber 1A and the product storage chamber 1B are cooled. Thereafter, the electromagnetic valve 5 is closed when the product storage chamber 1B falls below the lower limit temperature, and the compressor 4 is stopped when the product storage chamber 1A falls below the lower limit temperature. In this way, the product storage chamber 1A and the product storage chamber 1B are kept at a cooling temperature in the range from the lower limit temperature to the upper limit temperature, and the product storage chamber 1A is prevented from being overcooled while omitting the electromagnetic valve.
[0006]
When the switch 10 is on the heating side, the product storage chamber 1A is set to cooling, and the product storage chamber 1B is set to heating, the solenoid valve 5 is closed to stop the supply of refrigerant to the cooler 2B and energize the heater 3. When the upper limit temperature is reached, the power supply is stopped.
[0007]
[Problems to be solved by the invention]
Such a conventional vending machine is devised so as to simplify the configuration in which the product storage room 1A dedicated for cooling and the product storage room 1B for both cooling and heating are cooled by a single compressor 4. From the viewpoint of operating the compressor 4 efficiently, many problems remain.
[0008]
First, since the entire product storage room 1A is cooled or the entire product storage room 1B is cooled or heated, heat is absorbed or released through the entire main body cabinet 1, and further, the entire product is cooled or Since the heating is performed, the operation time of the compressor 4 and the energization time of the heater 3 are long, and the power consumption is increased.
[0009]
In addition, when the sales number of cold products and hot products are extremely different, for example, when the outside air temperature rises and the sales number of cold products increases more than expected, the number of cold products decreases first, and the product storage room 1A When it is necessary to replenish the product, it takes time to change the product storage room 1B to the cooling setting, and when the product is replenished, outside air enters the product storage room 1A and the product storage room 1B is set to be heated. Since heat flows out to the outside air, the operation time of the compressor 4 and the energization time of the heater 3 are further increased to increase the power consumption. Moreover, if it changes to a cooling setting, it will be necessary to cool the goods which were heated until then, and also an extra electric power will be consumed. On the contrary, when the number of sales is extremely reduced, it is necessary to continue cooling or heating the excess products.
[0010]
Further, since the product stored in the position away from the cooler 2A is not easily cooled, and similarly the product stored in the position away from the heater 3 is not easily heated, it is sufficient that the number of sales per hour increases. In some cases, products that are not cooled or heated are sold. In order to prevent this, it is sufficient to make the temperature in the cabinet uniform, but it is necessary to equip a fan having a high blowing capacity to always control the operation, which further increases power consumption.
[0011]
The present invention solves the above-described problems, and an object of the present invention is to provide a vending machine that can efficiently use a compressor and a heater, consumes less power, and can accurately respond to changes in the number of sales.
[0012]
[Means for Solving the Problems]
A first product storage room for storing products, a second product storage chamber for storing products, a cold product storage room for cooling and storing products by cooling means and storing them as cold products, and a product for heating and maintaining heat by heating means A hot product storage room for storing hot products, first product transport means for transporting products from the first product storage chamber to the cold product storage chamber, and products from the second product storage chamber to the hot product storage chamber Second product transporting means for transporting the product, first ventilation means for allowing cold air in the cold product storage chamber to flow into the first product storage chamber, and warm air in the hot product storage chamber flowing into the second product storage chamber A second ventilation means for causing the first conveying means to automatically convey the commodity corresponding to the number of sales of the cold merchandise, and the second conveying means to correspond to the number of sales of the hot commodity.

I sometimes let warm air flow in It is a vending machine.
[0013]
As a result, the power required for cooling and cooling and heating and heating corresponds to the number of sales, so that power consumption can be reduced, and a predetermined number of cold and hot products can be maintained, so that it is possible to accurately respond to changes in the number of sales. .

[0029]
FIG. 5 is a block diagram showing the configuration of the control system in this embodiment. In the figure, reference numeral 39 denotes an arithmetic processing unit, which counts the number of times the cold merchandise sales button 28a is pressed within a predetermined time by the timer function and the counter function. The first damper driving means 38a is operated to open the first damper 37a, and if it is less than the predetermined number of times, the first damper driving means 38a is operated to close the first damper 37a. The same applies to the hot product sales button 28b, the second damper 37b, and the second damper driving means 38b.
[0030]
The operation of the above configuration will be described. First, the operation of the first damper 37a will be described. FIG. 6 is a flowchart showing an operation related to the first damper 37a. During the operation of the cooler 2, the arithmetic processing unit 39 starts the timer at step 8 and sets the initial value of the counter to zero, and the predetermined value set in advance through a loop of step 9 → step 12 → step 13 → step 9. It is counted how many times the cold merchandise sales button 28a is actuated in time, that is, how many cold merchandise are sold. When the predetermined time elapses in step 9, the process proceeds to step 11, and it is determined whether or not the sales number N is equal to or greater than the predetermined sales number. If it is equal to or greater than the predetermined sales number N1, the process proceeds to step 14, and the arithmetic processing unit 39 causes the control means 30 to operate the first damper driving means 38a to open the first damper 37a. As a result, the cold air in the cold product storage portion 22a flows into the first product storage chamber 35a through the first air passage 36a, and the product 21 in the first product storage chamber 35a is also cooled, so that the cold product 21a is sold per hour. It is possible to prevent the number from rapidly increasing and selling uncooled products.
[0031]
In step 11, if the sales number N is less than the predetermined sales number N1, the process proceeds to step 14, and the arithmetic processing unit 39 causes the control means 30 to operate the first damper driving means 38a to close the first damper 37a. As a result, the cold air in the cold product storage chamber 22a does not flow into the first product storage chamber 35a, and the product 21 in the first product storage chamber 35a is not cooled, so the number of cold products 21a sold per hour decreases. Therefore, it is possible to prevent the power consumption of the cooler 2 from being increased by cooling and keeping a necessary number of products.
[0032]
Next, the operation of the second damper 37b will be described. FIG. 7 is a flowchart showing an operation related to the second damper 37b. This operation is performed in the same manner as the operation shown in FIG. 6 for the hot product 21b, and detailed description thereof is omitted. When the sales number N of the hot product 21b is equal to or greater than the predetermined sales number N2 within the predetermined time during the operation of the heater 3, the arithmetic processing unit 39 causes the control unit 30 to operate the second damper driving unit 38b to 2 Open the damper 37b. Thereby, the hot air in the hot product storage chamber 22b flows into the second product storage chamber 35b through the second ventilation path 36b, and the product 21 in the second product storage chamber 35b is also heated. Even if the number of sales increases rapidly, it is possible to prevent sales of products that are not sufficiently heated.
[0033]
If the sales number N of the hot products 21b within the predetermined time is less than the predetermined sales number N2, the arithmetic processing unit 39 causes the control unit 30 to operate the second damper driving unit 38b and close the second damper 37b. As a result, the hot air in the hot product storage chamber 22b does not flow into the second product storage chamber 35b, and the product 21 in the second product storage chamber 35b is not heated, so the number of hot products 21b sold per hour has decreased. In such a case, it is possible to prevent a necessary number of products from being heated and kept warm to increase the power consumption of the heater 3.
[0034]
(Example 3)
The third embodiment of the vending machine of the present invention will be described below with reference to the drawings.
[0035]
FIG. 8 is a side sectional view showing the configuration of this embodiment. Note that the same components as those in the second embodiment are denoted by the same reference numerals and detailed description thereof is omitted. In the figure, 40 is an auxiliary cooler that is installed in the first product storage chamber 35a and cools the interior thereof, 41 is an auxiliary heater that is installed in the second product storage chamber 35b and heats the interior, and 42a is the first product. A first temperature sensor 42b for detecting the temperature of the storage chamber 35a, and a second temperature sensor 42b for detecting the temperature of the second product storage chamber 35b. The auxiliary cooler 40 may be one of two evaporators on the same refrigeration cycle as the cooler 2 and may be configured to control the flow of refrigerant into the auxiliary cooler 40 using an on-off valve.
[0036]
FIG. 9 is a block diagram showing the configuration of the control system in this embodiment. The arithmetic processing unit 39 causes the control means 30 to operate and stop the auxiliary cooler 40 and the auxiliary heater 41 based on the outputs of the first temperature sensor 42a and the second temperature sensor 42b.
[0037]
The operation of the above configuration will be described. FIG. 10 is a flowchart showing the operation of this embodiment. In step 15, the arithmetic processing unit 39 checks whether the temperature of the first product storage chamber 35a is equal to or higher than a predetermined upper limit temperature T1 based on the output of the first temperature sensor 42a. The auxiliary cooler 40 is turned on and the process proceeds to step 18, and if less, the auxiliary cooler 40 is turned off and the process proceeds to step 18 in step 17. In step 18, it is checked whether the temperature of the second product storage chamber 35b is equal to or lower than a predetermined lower limit temperature T2 based on the output of the second temperature sensor 42b. Turn on and go to step 16, and if T2 is exceeded, turn off the auxiliary heater 41 and return to step 15.
[0038]
By the above operation, the first product storage chamber 35a is kept lower than the upper limit temperature T1, and even if the outside air temperature rapidly rises and the sales of the cold product 21a rapidly increase, the product conveyed from the first product storage chamber 35a 21 is cooled to a substantially predetermined temperature T1, so that the operating capacity of the cooler 2 can be increased more than necessary to prevent the temperature of the cold product in the vicinity of the cooler 2 from being excessively lowered or frozen. A large amount of cold products can be sold. Further, the second product storage chamber 35b is kept higher than the lower limit temperature T2, and even when the outside air temperature rapidly drops and the sales of the hot product 21b increase rapidly, the product 21 transported from the second product storage chamber 35b is almost the same. Since it is heated to a predetermined temperature T2, it is possible to prevent the hot product 21b in the vicinity of the heater 3 from being raised excessively by increasing the operating capacity of the heater 3 and preventing the hot product 21b in the vicinity of the heater 3 from being raised excessively. In addition to being sold in large quantities, it is possible to prevent the products in the second product storage chamber 35b from being frozen.
