Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inner box structure of a vending machine.

[0002]

2. Description of the Related Art As shown in FIG. 6, an inner box of a vending machine is composed of an inner box body 1 and an inner door 2 each having a heat insulating structure. A warming unit 3, a transport unit 4, and a chute 6 for transporting commodities paid out from the transport unit 4 to a product outlet 5 are provided. A heat insulating door 7 is attached to a lower portion of the inner door 2, and is always closed by its own weight.

The air flow 8 generated by operating the cooling / heating unit 3 circulates through the inner door 2 and the ventilation passage 9 of the transfer unit 4 to the upper part of the refrigerator as shown in FIG. The temperature is controlled so that the temperature approaches the set target temperature.

[0004]

According to this configuration, since the air flow 8 circulates to the upper part of the storage, not only the commodity near the payout unit 10 but also the transport unit 4
The temperature of the upper product packed in the can be set to the set temperature, but if the product is refilled, it takes too much time for the product near the payout unit 10 to reach the set temperature, and There is a problem that the waiting time for starting sales cannot be extended.

SUMMARY OF THE INVENTION An object of the present invention is to provide an inner box structure of a vending machine which can quickly set a product at a lower portion of a transport unit to a set temperature.

[0006]

An inner box structure of a vending machine according to the present invention has an inner box body having a heat insulating structure in which a plurality of heat insulating spaces are arranged in a horizontal direction, and a heat insulating cover for covering an opening of the inner box body. The interior is composed of the inner door of the structure and each insulation space in this interior is
A vending machine that houses a temperature control device and a transport unit that pays out a product, respectively, and that forms a vertically extending ventilation path between an inner surface of an inner door and a transport unit in each of the heat insulating spaces, wherein the inner door is provided. On each inner surface facing each of the heat insulating spaces, a closing body whose posture can be freely changed is attached to a position where the ventilation path is opened and a position where it is closed.

[0007]

According to this structure, when the temperature in the lower part of the refrigerator is to be intensively controlled, the closing body provided on the inner surface of the inner door is replaced with the ventilation path formed between the inner door and the transport unit. Operate with the position set to block. Therefore, the temperature-controlled air flow is prevented from flowing toward the upper part in the refrigerator by the closing member set at the position for closing the ventilation passage in the ventilation passage, and circulated in the lower part in the refrigerator to reach the temperature. Adjust.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 6 and 7 showing the conventional example will be described with the same reference numerals.

1 to 3 show a first embodiment of the present invention. As shown in FIG.
₁ to 11 ₄ are provided. Closure 11 ₁ to 11 ₄ 1
As shown in FIG. 1 (a), it is rotatable between a first position in which the air passage 9 is opened upright and a second position in which the air passage 9 is closed upright as shown in FIG. 1 (b). Has become.

[0010] Specifically, the closure 11 ₁ to 11 ₄ are rotatably pivoted core unit with screws 12 to the inner door 2, as shown in FIG. 3
13 and a closing body 15 formed with urethane and having a recess 14 in the center of the back surface into which the core 13 is inserted. The closing body 11 ₁ is located at a second position for closing the air passage 9. ~ 11
_{When the} inner door 2 is closed with the setting of ₄ , the surface of the closing body 15 comes into contact with the transport unit 4 and is elastically deformed as shown by the imaginary line A in FIG. You.

[0011] Thus configured to, when the inner door 2 closed in a state of setting the closure 11 ₁ to 11 ₄ in the first position for opening the air passage 9, generated by driving the cooling and warming unit 3 The air flow 8 thus circulated to the upper part of the refrigerator through the ventilation passage 9 and the like, and the temperature is controlled so that the temperature in the refrigerator approaches the set target temperature. At the second position for closing the air passage 9, the closing bodies 11 _{1 to} 11
When the inner door 2 closed in a state in _{which 4} sets the air flow 8 occurring driving a cooling and heating unit 3, closure 11 ₁ to 11
₄ prevents it from going to the upper part of the refrigerator and circulates at the lower part of the refrigerator to regulate the temperature.

Accordingly, closure 11 ₁ to 11 to the second position
_{When 4} is set, the temperature of the commodity near the payout unit 10 can be quickly set to the set temperature, and the waiting time for sales start can be shorter than before.

[0013] Figure 4 and Figure 5 illustrates an alternative embodiment of the closure 11 ₁ to 11 _4. In the first embodiment described above, closure 11 ₁ to 11 ₄
The first position and is rotated to the second position has been open and close the air passage 9, closure 11 ₁ to 11 ₄ of the second embodiment, notch for folding as shown in FIG. 5 16 ₁ , 16 ₂ , 16 ₃
Is attached to the inner surface B of the inner door 2 with screws 18 ₁ and 18 ₂ , and a pin 19 is attached to the inner surface B of the inner door 2.
₁ and 19 ₂ are provided. Furthermore, the holes 20 _1, 20 ₂ for escaping the pin 19 _1, 19 ₂ in the case where the synthetic resin plate 17 was set closure 11 ₁ to 11 ₄ as shown in FIG. 4 in the first position,
Closure 11 ₁ to 11 ₄ of the when set to the second position the pin 19 _1, 19 ₂ engages in the hole 20 _3, 20 ₄ are bored.

In the case of the second embodiment, the closing body 11 ₁
To 11 ₄ almost able to fully open the air passage 9 when the set to the first position, can be improved than the first embodiment the efficiency when adjusting the temperature up to the top of the refrigerator .

[0015]

As described above, according to the present invention, the ventilation passage extending vertically between the inner surface of the inner door and the transport unit can be opened and closed by the closing member, and the closing member closes the ventilation passage. By driving in a position where
The airflow whose temperature has been adjusted is prevented from flowing toward the upper part of the refrigerator by the closing body, and circulates in the lower part of the refrigerator. Time can be shortened than before. Further, since the place where the closing body is provided is the inner surface of the inner door, the switching operation of the closing body can be easily performed by a person, and the operability is excellent. In addition, since the closing body is attached to each inner surface facing each heat insulation space of the inner door, it is possible to set temperature control by switching the closing body for each heat insulation space, such as replenished products as sold out The temperature of only a specific product can be intensively adjusted, and the problem of intensively adjusting the temperature of a product that has already reached an appropriate temperature can be prevented.
