And a setting device for easily setting the cooling or heating temperature of each of the above-mentioned refrigerators.

[0002]

2. Description of the Related Art FIG. 1 shows a configuration of a vending machine cooling / heating system according to an embodiment of the present invention. The prior art will be described with reference to FIG. Conventionally, the current mode temperature setting change validating means 10A shown in FIG. 1 is not provided.

In FIG. 1, reference numerals 1 (1A, 1B) denote interiors for cooling or heating and storing the products, respectively, which are referred to as a left interior and a right interior, respectively. 2 (2A, 2B) is 1A,
1B internal temperature sensor for detecting the internal air temperature, 4
(4A, 4B) is a heater for heating the above-mentioned interior 1A, 1B, respectively, and 5 (5A, 5B) is a left interior 1A,
An evaporator (also referred to as a cooler) for cooling the inside of the refrigerator provided in the right refrigerator 1B.

[0004] Next, reference numeral 9 denotes a refrigerator (also referred to as a motor / compressor), and 7 (7A, 7B) are refrigerant shut-off valves as electromagnetic valves for opening and closing the refrigerant sent from the refrigerator 9 to the evaporators 5A, 5B, respectively. is there. Reference numeral 10 denotes a cooling / heating control unit for controlling the above-described units to cool or heat the insides 1A and 1B to a predetermined temperature, respectively, and 11 (11A and 11B) to cool the insides 1A and 1B (C and C, respectively). A mode changeover switch (hereinafter, also abbreviated as SW) for switching and setting a mode of heating (abbreviated as H).

On this side, the mode switch SW11
A, the combination of the cooling or heating modes for each of the inside 1A, 1B which can be set by 11B are CC, CH, HC,
HH. Reference numeral 12 denotes a data setter for operating and inputting a set temperature or the like of the inside of the refrigerator to the cooling / heating controller 10 and includes a keyboard and the like.

The cooling / heating control unit 10 includes a mode switching switch 11A,
In accordance with the cooling or heating mode for each of the compartments set by 11B, each of the compartments 1A and 1B is provided with a data setting device 12 respectively.
While detecting the temperatures of the interiors 1A, 1B with the sensors 2A, 2B so that the temperatures of the corresponding modes set by the above are obtained,
The on / off control of the refrigerator 9 and the refrigerant shutoff valve 7A or 7B or the heater 4A or 4B is performed.

For example, when the two compartments 1A and 1B are both in the cooling mode, the cooling / heating control unit 10 turns on the refrigerator 9 and determines whether each of the compartments 1A and 1B is at or above the set temperature. The refrigerant shutoff valves 7A and 7B are turned on and off, respectively. Then, both the insides 1A and 1B become lower than the set temperature,
When the refrigerant shutoff valves 7A and 7B are both closed, the refrigerator 9 is turned off. Further, when both the insides 1A and 1B are set to heating, the cooling / heating control unit 10 turns on and off the heaters 4A and 4B, respectively.

As a method of setting the cooling / heating control temperature for each vending machine in each vending machine, there is a method of setting a common cooling temperature and a heating temperature irrespective of the arrangement in the vending machine. Since the temperatures of the interiors 1A and 1B are mutually affected by the cooling or heating state of the other (neighboring) interiors, the temperatures in the interiors of the interiors usually depend on the combination of the cooling / heating modes in each interior. Is set.

[0009]

However, in order to perform such temperature setting, it is necessary to specify a combination of cooling and heating modes in the refrigerator by the data setting device 12 and to set the respective control temperatures in the refrigerator. There is a problem that the setting procedure becomes extremely complicated. Therefore, an object of the present invention is to provide a cooling / heating temperature setting device for a vending machine which can simplify such a temperature setting procedure.

[0010]

In order to solve the above-mentioned problems, the present invention relates to a vending machine which stores or sells a product by cooling or heating the product, and comprises a plurality of storages (1A) for storing the product. , 1B, etc.) and mode setting means (mode switching SW) for setting a cooling or heating mode for each of the compartments.
11A, 11B, etc.) and inside-chamber temperature detecting means (such as inside-chamber temperature sensors 2A, 2B) for detecting the temperature inside each of these boxes.
Cooling / heating means (refrigerator 9, refrigerant shutoff valves 7A and 7B, evaporator 5A,
5B, heaters 4A, 4B, etc.), and set temperature storage means for storing a set temperature for each of the refrigerators for each combination of the cooling or heating modes set via the mode setting means. Based on the cooling or heating mode setting for each of the compartments via the mode setting means, the temperatures in the respective compartments detected through the inside-of-compartment temperature detecting means are respectively set to the combination of the mode setting for each of the compartments. Correspondingly,
In a vending machine having means for controlling the driving of the cooling / heating means (such as a cooling / heating control unit 10) so that the temperature becomes the set temperature stored in the set temperature storing means, an operation input via the data setting means is performed. Means for storing the set temperatures of the respective compartments in a storage area in the set temperature storage means corresponding to the combination of the cooling or heating modes of the respective compartments currently set by the mode setting means (current state Mode temperature setting change validation procedure 10A).

[0011]

The internal temperature setting data set by the data setting unit 12 is made effective only for the combination of the cooling / heating mode for each of the containers currently set by the mode switch SW11. This eliminates the need to specify a conventional cooling / heating mode combination when the set temperature is input from the operation unit 12.

[0012]

Next, an embodiment of the present invention will be described with reference to FIGS. In the present invention, a current mode temperature setting change validating means 10A is provided in the cooling / heating control section 10 shown in FIG. 1 as a partial function section for sharing functions relating to the present invention. That is, this means 10A uses the mode switching SW 11A, 11
B is stored in the corresponding temperature setting data storage area as temperature setting data effective only for the combination of the different modes inside the refrigerator currently set by B.

FIG. 2 is a flowchart for explaining in detail the operation of the current mode temperature setting change validating means 10A of the cooling / heating control section 10, and reference numerals S1 to S13 denote steps in FIG. FIG. 2 shows an example in which, in the initial processing at the time of turning on the power, the temperature data previously set and stored for each of the refrigerators is changed for each combination of the cooling and heating modes in each refrigerator. However, it is clear that the application of the present invention is not limited to such a change of the temperature setting data, but can be applied to the initial setting.

Referring now to FIG. 2, the current mode temperature setting change validating means 10A of the cooling / heating control unit 10 determines that the data setting unit 12 has input the set temperature change data for each of the insides 1A and 1B. Then (S1, branch Y), the input temperature data is temporarily stored (S2), and it is determined whether or not the current setting state of the mode switching SWs 11A and 11B is the CC mode (S3). If the mode is the CC mode (branch Y), the temperature setting data in the initially set CC mode area is rewritten to the newly input set temperature change data (S6), and thereafter, the new temperature is set. The control operation in the CC mode is performed using the setting data (S1).
0).

If the current mode switch SW11 is set to C
If the mode is not the -C mode, it is sequentially determined whether the mode is the CH mode (S4) or the HC mode (S5) in the same manner as described above, and the initial setting of the mode combination area determined to be the current setting mode is performed. The temperature setting data is rewritten to the newly input set temperature change data (S7 to S9), and thereafter, the control operation of the mode according to the new set temperature data is executed (S1).
1 to S13).

[0016]

According to the present invention, the temperature setting data for each of the refrigerators input through the data setting device 12 is stored in the data setting device 1.
2 is stored only in the temperature setting data area corresponding to each cooling / heating mode combination currently set by each mode by the mode switching SW11 without requiring the input operation of the specification of the cooling / heating mode combination by each chamber by 2. As a result, not only can the conventional complicated temperature setting operation procedure be a common simple procedure irrespective of the combination of the cooling and heating modes, but also the new temperature setting data can be stored in the current cooling and heating mode. Since it is effective only for the mode combination, it is not necessary to reset data every time the mode is switched, and the effect that it is practically easy to use is obtained.
