Description

TECHNICAL FIELD The present invention relates to a vending machine with a microwave oven, and particularly to a microwave oven for carrying refrigerated / frozen food sent from a storage according to a sales signal into an oven. After heating by irradiating
The present invention relates to the improvement of a series of sales operation mechanism that is carried out of an oven and sent to a sales outlet.

(B) Conventional technology Conventionally, regarding this type of vending machine with a microwave oven,
Various mechanisms have been proposed. For example, Japanese Patent Publication Sho 56-2757
The example shown in Japanese Patent Publication is also an example. The device shown in this publication is provided with a door that opens and closes the side opening of the oven, receives the food from the storage in the spare room, and when the door is closed, the turntable attached to the back of this door enters the oven. When the door is opened again after receiving the food and heating it by microwaves, the food is configured to drop downward from the bottom opening of the oven.

(C) Problems to be Solved by the Invention However, according to the conventional device disclosed in the above publication, the door body and the turntable are integrally formed, and since they operate, the structure becomes complicated. Therefore, it is possible to completely shield the oven to prevent electric wave leakage during microwave irradiation.
Considering the dimensional accuracy of parts, it becomes very difficult. Further, since the door body, which is integrated with the turntable and becomes heavier in weight, is moved back and forth, a large power is required for the drive device, resulting in an increase in size and cost. Further, since the food is dropped and delivered from the bottom surface of the oven to the selling port after heating, the selling port is provided at a position lower than that. This means that for the total volume of the vending machine,
There are many spaces that do not function for product storage (sales outlets, oven installation space), the product storage space cannot be expanded, and one product cannot sell many products, resulting in poor sales efficiency. Has become. Further, since the position of the selling port is low, it has a drawback that it is difficult to take out food.

Further, since the food is simply pushed by the back surface of the door body and put in the oven, it is not always placed near the center position of the turntable, and heating unevenness occurs when it is microwave-heated as it is. The food that has fallen into the preliminary chamber sometimes stays in a vertically long shape and remains in that position in the oven, and in that case, uneven heating occurs. In this way, the mounting position on the turntable is unstable, or uneven heating occurs due to the inconvenience that the posture on the turntable is not constant, while the uneven operation of the turntable due to uneven distribution of food, The reliability of the operation may be lost.

The present invention has been made in view of the above points, by a simple mechanism that does not require a large power, carry in and out of food ovens reliably, to achieve safe and uniform heating, An object of the present invention is to provide a vending machine with a microwave oven which is configured so that it is easy to take out a product, the serviceability is improved, and the number of products accommodated is increased to improve the sales efficiency.

(D) Means for Solving the Problems The present invention includes a microwave oscillating means and a turntable on which food is placed, and front and rear side surfaces are opened to form a first opening on a rear surface and a second opening on a front surface. An oven, a product holding part configured in the front part of the first opening for temporarily storing and holding food carried out from a product storage based on a sales signal, and slidable along the holding part. And a second door opening through which the food held in the product holding portion is carried into the oven through the first opening when the first opening is opened and closed. And a second door body configured to be openable and closable, and when advancing into the oven, the food on the turntable is carried out of the oven through the second opening, and when retracting to the outside of the oven, It also serves as a bottom member It is composed of a product extruding section.

Further, on the back side of the first door body, there is integrally provided a product pressing portion for pushing the product on the product holding portion and sending it into the oven when the first door body moves horizontally from the open state to the closed state. When the step is provided between the product holding part and the turntable, and the first door completely closes the first opening of the oven, the product pressing part is located inside the oven from the tip of the product holding part. It was made to appear.

(E) Product The food is dropped from the store by the sales signal, the first door is opened, and the food is received by the product holder. Then, in the process of closing the first door body, the food is placed on the turntable by the product pressing portion on the back surface of the door body without being displaced. As a result, the food is heated uniformly during the next micro-heating. After heating, the product extruding part moves forward, and the tip of the extruding part reliably pushes the heated food product through the opened second opening to reach the selling port. After extruding the product, the product extruding part retracts,
It stands by as a bottom member that receives the food to be sold next. In this way, food can be carried into the oven simply by reciprocating only the door.

A first door body 23 slidable in the direction of arrow b is provided between the first opening 21 and the product holding portion 10. Like the fixed plate that reciprocates, the first door body 23 can be reciprocated by a driving means including an electric motor, a pinion, a rack gear and the like. The first door body 23 has a hole 24 (see FIG. 2) for penetrating the dielectric rod 11, so that the first door body 23 and the dielectric rod 11 can slide with respect to each other. ing. Of course, a through hole is also formed between the vertical dielectric rod and the first door body 23. Therefore, the first opening 21 can be freely opened and closed by the first door body 23. And the first door body 23
On the back surface of the product, there is integrally provided a product pressing part 25 for pressing the food 1 on the dielectric rod 11 into the oven 16 in the process of closing it. Here, when the first door body 23 is closed, the product pressing portion 25 is configured to protrude inside the oven 16 from the tip of the dielectric rod 11, and the tip of the dielectric 11 is positioned above the turntable 20. And a step 26 is formed between them.

On the other hand, a second door body 27 is also provided in the second opening 22 of the oven 16, and the second door body 27 is slidable in the vertical direction (arrow c direction) along the second opening surface. 28 is this second
The opening of the door body 27 allows the oven 16 to pass through the second opening 22.
At the sales outlet where the heated food 1 that is carried out is received, the height does not change positionally with the second opening 22, and the sales outlet 28 is not at a low position, making it easy to take out the food 1. There is. Reference numeral 29 is a sales door whose pivot is supported at the upper end.

Next, the structure and operation of the microwave oven part, which is the main part of the present invention, will be described in more detail with reference to FIGS. 30 is the left and right side members of the product holding unit 10 described above,
It is a dielectric rod that reliably guides the fallen food 1 from the storage 3 into the product holding unit 10. The dielectric rod 30 has a front end removably engaged with an inner wall of the oven 16 and a rear end removably engaged with a mounting plate 31 provided separately. Reference numeral 14 is a product extruding member attached to the tip of the dielectric rod 11.

Electric power is supplied to the electric motor sliding on 27, and the second door body 27 is operated to open the second opening 22. Detecting that the second opening 22 is in the open state, electric power is supplied to the electric motor which slides on the fixing plate 13 of the dielectric rod 11, and the fixing plate 13 is operated to move the dielectric rod 11 to the position shown in FIG. As described above, the food 1 is pushed out of the oven by the product pushing member 14 at the tip of the rod by operating in the second opening direction. The food 1 is carried out to the selling port 28 provided on the front surface of the second opening 22. At the same time when the fixing plate 13 returns to the waiting position after the carrying-out is completed, the second door body 27 is closed and a series of operations is completed, and the waiting state is established as shown in FIG. In this way, the food 1 is moved laterally from the product holding unit 10 to the microwave oven 15 and further to the selling port 28, so that the space occupied by these can be reduced in the height direction, and the storage space is correspondingly reduced. The volume of 3 can be expanded and the number of products accommodated can be increased. Further, it is not necessary to install the selling port 28 below, and the product can be taken out easily.

By the way, there is a step between the turntable 20 and the tip of the dielectric rod 11.
By providing 26 and the product pressing portion 25 on the back side of the first door body 23, the following advantages can be obtained. That is, as shown in FIGS. 6 to 8, for example, a vertically long food 1A
6 is carried out from the storage 3 as shown in FIG. 6, is held in the product holding unit 10 in its vertical posture, and is carried in that state into the microwave oven 15 by closing the first door body 23. Also in the case, as shown in FIG. 7, when the product pressing portion 25 and the step 26 are placed on the turntable 20, the food 1A falls,
It is placed in a stable posture as shown. by this,
The food is not evenly placed on the turntable 20 and the food is heated uniformly. Then, as shown in FIG. 8, when the first door body 23 is completely closed, the product pressing portion 25 comes out from the tip of the product holding portion, that is, the tip of the dielectric rod 11 to the inside of the oven, so that the food 1A is surely discharged. Will be transported onto the turntable 20.

(G) Effect of the Invention As described above, according to the present invention, the product received in the product holding unit from the storage is brought into the product on the rear surface of the oven by the first door body that slides back and forth along the product holding unit. It is put in through the mouth and placed on the turntable in the oven. After heating, the product is carried out to the side by the opening operation of the second door body that opens and closes the product carry-out port formed on the front surface of the oven and the product pushing member that enters the oven. Therefore, the goods can be carried into the oven only by moving the first door body back and forth at the end, and the driving device thereof need only be a small one with small power, and the configuration can be simplified. Owing to the simplified structure, an oven shield structure for preventing microwave leakage can be easily obtained. And since the loading and unloading of products to and from the oven can be achieved by moving in the horizontal direction at all, it is possible to incorporate the heating device into the vending machine body without taking up a large space in the height direction. As a result, the storage volume can be increased, the number of products stored can be increased, and the sales efficiency can be improved.
Also, since the food after heating is carried out from the side of the oven,
The sales outlet can be set to a high position as needed, and in that case, the product can be taken out easily. Further, since a step is formed between the tip of the product holding portion and the turntable and a product pressing portion is provided on the back surface of the first door body, the product is placed on the turntable in a stable and constant low posture, so that the heating is performed. The unevenness is less likely to occur, the product is stable even when the turntable rotates, and reliable operation is obtained.
