Description

The present invention relates to an improvement in a vending machine equipped with a microwave oven, and more particularly to an improvement in uneven heating of food stored in an oven of a microwave oven.

(B) Conventional technology A vending machine with a microwave oven that heats frozen or refrigerated food products that are carried out of storage at a sales signal with a microwave oven, and after heating, goes out to a product outlet and provides the vending machine to customers. It is disclosed in Japanese Patent Publication No. 56-2577. According to the publication, food is placed on a rotating plate arranged behind a door body, and microwaves are radiated to the food on the rotating plate by microwave oscillating means provided at an appropriate place in an oven and heated. You.

(C) Problems to be Solved by the Invention However, according to the above-mentioned conventional apparatus, the oscillation of the microwave and the driving of the stirrer fan start simultaneously. Therefore, since the microwave is irradiated from the inside of the stirrer fan which is not in a steady rotation again, the irradiation state of the microwave on the food on the turntable is not stabilized, and uneven heating occurs.

The present invention has been made in order to solve the above-mentioned problems, and in order to prevent uneven burning of a finished heat, an electron configured to uniformly disperse microwaves to be irradiated into an oven and obtain stable irradiation at the same time. It is an object to provide a vending machine with a stove.

(D) Means for Solving the Problems The present invention takes out a frozen or refrigerated product housed in a storage by a sales signal, receives the taken out food in an oven having microwave oscillation means, and heats the product after microwave heating. In a vending machine with a microwave oven to be sold to a product outlet, before a product is carried out from the storage, start a rotary drive of a stirrer fan that stirs microwaves provided in the oven, Control means is provided for starting microwave oscillation after the product is carried into the oven.

(E) Operation Before the product is unloaded from the storage, the rotation of the stirrer fan is started, and the product is brought into the oven from the storage and brought into a steady state of rotation until the micro liquid is oscillated, and microwave oscillation starts. At the same time as stabilizing the irradiation, the stirrer fan keeps rotating steadily during the oscillation of the microwaves, and performs uniform irradiation of the microwaves to prevent unevenness of the finished product from being heated.

(F) Example Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is a schematic explanatory view of the internal configuration of a vending machine to which the present invention is applied, and FIG. 2 is a flowchart illustrating the vending operation of the vending machine. First, FIG. 1 will be described.
In the main body 1 of the vending machine, there is provided a storage 4 in which a plurality of product storage columns 3 for storing the food 2 while keeping the food 2 at a constant temperature are provided. The appropriate bend mechanism provided in the above operates to carry out the selected product 2 from the column 3. The conveyed food 2 falls to the chute 6 and is sent out to the room with the microwave oven 9 through the dropout 8 by opening the in-compartment discharge door 7 provided below the chute 6. The food 2 is first received in a product holding section 10 arranged in the rear area of the microwave oven 9. The product holding portion 10 is provided with a plurality of dielectric bars 11 arranged horizontally on the bottom and slidably reciprocating back and forth (arrow a) through a first door body, which will be described later. It is configured in a concave basket shape by a plurality of dielectric bars arranged vertically in the state. On the other hand, the microwave oven 9 is provided with a first opening 12 for carrying in food, and a first door 13 for opening and closing the first opening 12 is moved in the front-rear direction in the product holding unit 10 as shown by an arrow b. It is slid. Therefore, the first door
The food 2 on the product holding part 10 when 13 opens and closes
Through the first opening 12 into the oven 9A provided with microwave oscillation means (not shown). Therefore the first door body
On the back of 13, a pressing portion 14 that presses against the food 2 and presses it is provided integrally. And food 2 in oven 9A
On which is mounted and rotated by driving means 15 such as an electric motor
A stirrer fan 18 for uniformly diffusing the microwave introduced by the waveguide 17 is provided above and opposite thereto. Stirrer fan 18
Is driven to rotate by an electric motor or the like. Where the stirrer fan
Reference numeral 18 designates that the food product 2 from the storage 4 is rotated before being put into the oven 9A, while the microwave oscillation is activated when the first door 13 is closed, Before the oscillation, the stirrer fan 18 is controlled to be driven to rotate. The turntable 16 and the stirrer fan 18 are designed to rotate steadily during microwave oscillation. When the heating of the food 2 is completed, the second
The opening 19 is opened by the opening of the second door body 20 that slides up and down. Subsequently, the above-described dielectric bar 11 starts to move forward,
The food 2 on the turntable 16 is conveyed out of the oven 9A at its tip, and is taken out to the product outlet 21. The dielectric 11 has a rear end attached to a fixed plate 22 that is moved by a reciprocating mechanism including an electric motor, a pinion, a rack gear, and the like. Reference numeral 23 denotes a sales port door, and reference numeral 24 denotes a refrigeration unit that cools the storage 4.

Next, the selling operation of the vending machine having the above configuration will be described with reference to the flowchart of FIG. Insert the required amount of coins (Step 10) and operate select button 5 (Step 20)
Then, the stirrer fan 18 starts (step 30).
The vent mechanism operates to transport the food 2 (step 40),
The first door 12 of the microwave oven is opened (step 50). The storage door 7 is opened and closed (steps 60 and 70), and the first door body is opened.
Oven 9A by closing 12 (step 80)
The food 2 is carried in, is placed on the turntable 16, and starts rotating (step 90). Microwave oscillation starts while the stirrer fan 18 is rotating at a steady speed, and stops after oscillating for a predetermined period of time (steps 100 and 110). After the rotation of 18 is stopped (Steps 120 and 130), the second door body 20 of the microwave oven is opened (Step 140), and is carried out of the microwave oven by sliding the pushing member (Step 150), and the second door body 20 is moved. After closing (step 160), a series of operations is completed, and a standby state is set.

(G) Effect of the present invention As described above, the present invention controls the stirrer fan that diffuses microwaves in the oven to rotate before microwaves oscillate. It is rotating, and microwave irradiation is stabilized from the start of microwave irradiation. Therefore, the food on the turntable is uniformly irradiated, and the finish of heating becomes good, and uneven burning can be prevented.
