Second, it consists of a plate pinion moving together with the bottom plate, and a top plate that advances further by the rotation distance of the plate pinion by the rotation of the plate pinion, so that the top plate on which the frozen food is placed is located at the distance that the bottom plate is advanced. It will be able to proceed further.

Accordingly, even if the size of the device is reduced, there is an effect that the top plate withdrawal distance from the case can not be reduced.

That is, as the size of the device is reduced, the efficiency of the installation space of the device is increased.

Hereinafter, with reference to the accompanying Figures 1 to 6b will be described for the frozen food heating device for vending machine according to a preferred embodiment of the present invention.

The frozen food heating device for a vending machine includes a case 100, a microwave generator 200, and a chamber 300.

The case 100 forms a frame of a frozen food heating device for a vending machine, and a predetermined space is formed inside the chamber 300 and the cooking device 200.

At this time, the upper and lower spaces of the case 100 are configured such that the cooking apparatus 200 is installed, respectively, and the chamber 300 is configured in the middle of the inside.

At this time, in the case 100, the part corresponding to the chamber 300, the inlet 110 to which the frozen food is input from the frozen food storage (to be described later), and the outlet 120 to which the cooked frozen food is discharged to the outside. ) Is formed.

Next, the cooking apparatus 200 serves to cook the frozen food by heating it.

The cooking apparatus 200 generates microwaves, and is the same as the principle of the microwave oven used in daily life.

In this case, the cooking apparatus 200 is installed above and below the space portion of the case 100 with respect to the chamber 300.

Accordingly, since the frozen food is irradiated with electromagnetic waves in the up and down directions, the cooking time can be shortened and evenly cooked, unlike the prior art, which is irradiated only in one direction.

At this time, the cooking apparatus 200 is preferably installed in each of the upper and lower portions of the case 100 to further shorten the cooking time.

Next, the chamber 300 accommodates the frozen food, and includes a space for cooking the frozen food by the cooking apparatus 200.

The chamber 300 includes a body 310, a fixed rack 320, a transfer rail 330, a lower plate 340, a plate pinion 350, an upper plate 360, and a motor 370. ), And a power transmission means (380).

The body 310 constitutes an exterior of the chamber 300, and as shown in FIG. 2A, an upper panel 311 constituting an upper portion, a lower panel 312 constituting a lower portion, and an upper panel 311. And a side panel 313 vertically supporting the lower panel 312.

With this configuration, the chamber 300 is formed with an outlet 300a and an inlet 300b.

The outlet (300a) and the inlet (300b) is a passage through which the frozen food is discharged from the chamber 300 to the outside through the discharge port 120 of the case 100 and the frozen food through the inlet 110 of the case 100 The passage is introduced into the chamber 300.

That is, the outlet 300a of the chamber 300 corresponds to the discharge port 120 of the case 100, and the inlet 300b of the chamber 300 corresponds to the inlet 110 of the case 100.

In addition, electromagnetic holes 311a and 312a are formed in the upper panel 311 and the lower panel 312, respectively.

The electromagnetic holes 311a and 312a are through-holes that allow microwaves of the cooking apparatus 200 to be irradiated into the chamber 300.

In this case, it is preferable that two electromagnetic holes 311a and 312a are formed in the upper panel 311 and the lower panel 312, respectively.

This is because the number of cooking apparatuses 200 installed at the top and bottom of the case 100 is two.

In addition, the electromagnetic hole 311a formed in the upper panel 311 and the electromagnetic hole 312a formed in the lower panel 312 may be disposed to be offset from each other, rather than being aligned in a straight line.

This is to further widen the irradiation range of electromagnetic waves for frozen foods.

Next, the fixing rack 320 is provided for the rotation of the plate pinion 350, it is fixed to the lower panel 312.

At this time, the fixed rack 320 is fixed in the direction of the outlet (300a) and the inlet (300b) of the chamber 300.

Next, the transfer rail 330 is provided for smooth movement during the movement of the lower plate 340, is fixed to both sides of the lower panel 312, respectively.

At this time, the transfer rail 330 is also fixed in the direction of the outlet 300a and the inlet (300b) of the chamber 300.

Next, the lower plate 340 serves to discharge the upper plate 360 through the inlet 110 of the case 100 or the outlet 120 of the case 100 while being transported along the transfer rail 330. .

The lower plate 340 is formed of a square plate, and the sliding member 341 corresponding to the transfer rail 330 is installed at both ends.

That is, the sliding member 340 is coupled to the transfer rail 330 it is possible to smoothly slide the lower plate 340.

And, one side of the lower plate 340 is formed with a pinion hole 342 for placing the plate pinion 350 to be described later.

The pinion hole 342 penetrates the upper and lower surfaces of the lower plate 340 and is formed larger than the diameter of the plate pinion 350 so that the plate pinion 350 can be rotated.

In addition, a plurality of rollers 343 may be installed on the upper plate 340 in the direction of the transfer rail 330.

This is to ensure that when the top plate 360 is transferred, it can be smoothly transferred.

In addition, the coupling portion 344 is installed at a portion where the pinion ball 342 is formed among the upper portions of the lower plate 340.

The coupling part 344 is for axial coupling of the plate pinion 350, and a bearing (not shown) for smooth rotation of the plate pinion 350 is installed therein.

Next, the plate pinion 350 serves to transport the upper plate 360 while being transported along the fixed rack 320 by the lower plate 340.

At this time, the plate pinion 350 is axially coupled to the bearing of the coupling portion 344 coupled to the lower plate 340 is disposed in the fixed rack (320).

Accordingly, the plate pinion 350 is conveyed together along the fixed rack 320 by the transport of the lower plate 340, and is rotated about the coupling part 344.

That is, since the plate pinion 350 rotates at the same time as the traveling distance of the lower plate 340 advances, the upper plate plate 360 coupled to the plate pinion 350 not only transfers the plate pinion 350 but also the plate. It can proceed further by the rotation distance of the pinion (350).

Next, the upper plate 360 is selectively withdrawn through the inlet 110 of the case 100 and the discharge port 120 of the case 100 while the cooking is completed frozen food from the chamber 300 of the case 100 It discharges to the outside, or serves to inject the frozen food for cooking into the chamber 300.

The upper plate 360 is disposed above the lower plate 340, and is also formed of a square plate.

In particular, the upper surface of the top plate 360 is preferably flat to facilitate the seating of frozen food.

In this case, the flow rack 361 is fixed to the bottom of the upper plate 360 along the entrances 300a and 300b of the chamber 300.

The flow rack 361 is coupled to an upper portion of the plate pinion 350 disposed in the pinion hole 342 of the lower plate 340.

Then, the guide member 362 is provided on the bottom of the upper plate 360.

The guide member 362 is for smooth transfer of the upper plate 360, and corresponds to the roller 343 installed on the lower plate 340.

Next, the motor 370 generates power to transfer the lower plate 340 toward the outlet 300a or the inlet 300b of the chamber 300.

At this time, the motor 370 is installed on one side of the chamber 300.

Next, the power transmission means 380 serves to transfer the lower plate 340 by receiving the power of the motor 370, and is installed between the lower plate 340 and the motor 370.

At this time, the power transmission means 380 includes a drive pinion 381 axially coupled to the motor 370, and a connecting member 382 for connecting the lower plate 340 and the drive pinion 381.

At this time, one end of the connection member 382 is fixed to the lower plate 340, the other end of the connection member 382 includes a drive rack 382a coupled to the upper portion of the drive pinion 381.

On the other hand, it is preferable that the rolling member 360a is installed on both sides of the bottom surface of the upper plate 360 so as to smoothly transfer the upper plate 360.

In addition, a control panel PLC is installed below the case 100 as shown in FIG. 1.

The control panel controls the cooking time for each product, and includes a memory unit (not shown) in which a numerical value for the cooking time is input by a separate computer (not shown).

That is, the administrator can selectively adjust the cooking time input to the memory unit by selectively operating the computer.

At this time, the control panel is a signal is input by the selection button (not shown) installed in the cabinet (not shown) constituting the appearance of the vending machine, it is possible to individually control by giving one input and output to each frozen food.

And, although not shown, the frozen food storage for supplying frozen food is installed on the outside of the case 100.

At this time, a conveyor (not shown) is installed between the frozen food reservoir and the inlet 110 of the case 100, and the frozen food is stored in the chamber 300 through the inlet 110 of the case 100 along the conveyor from the frozen food reservoir. It is transferred to the top plate 360 of).

Hereinafter, the operation of the frozen food heating device for vending machine made of the above configuration.

First, the consumer selects the desired frozen food by operating the selection button installed in the vending machine.

At this time, the input signal is input to the control panel, the control panel recognizes this to transfer the frozen food selected from the frozen food storage to the chamber 300 inside the case 100.

At this time, the motor 370 generates power to rotate the drive pinion 381, and the drive pinion 381 pushes the drive rack 382a toward the inlet 110 of the case 100.

At this time, the connecting member 382 connected to the driving rack 382a transfers the lower plate 340 to the inlet 110 of the case 100.

In this case, the sliding member 341 of the lower plate 340 is transferred along with the lower plate 340 along the transfer rail 330, the plate pinion 350 axially coupled to the coupling portion 344 of the lower plate 340 ) Is also conveyed along the fixed rack 320.

At this time, the flow rack 361 coupled to the upper portion of the plate pinion 350 is pushed in the rotation direction of the plate pinion 350 by the rotation of the plate pinion 350, the upper plate fixed to the flow rack 361 Naturally, the plates 360 are conveyed together.

At this time, the guide member 362 of the upper plate 360 is guided to the roller 343, and as the bottom surface of the upper plate 360 is clouded by the rolling member 360a, the upper plate 360 smoothly transfers. You can do it.

Thereafter, the upper surface of the upper plate 360 is exposed to the outside through the inlet 110 of the case 100 to correspond to the conveyor.

In this process, the upper plate 360 is not only conveyed by the transport distance of the lower plate 340, but also the rotation distance of the plate pinion 350 because the lower plate 340 is rotated to rotate the plate pinion 350 As much as it can be transported.

As such, since the transport distance is further increased by the rotation distance of the plate pinion 350 only by the transport of the lower plate 340, the size of the device itself is reduced.

That is, even if the length of the fixed rack 320 is shortened, since the draw length of the top plate 360 can be doubled, the size of the device is reduced as the length of the fixed rack 320 is reduced.

If it is not the configuration as described above, that is, without the configuration of the plate pinion 350, because the length of the fixed rack 320 has to be long, the size of the device will of course be made large.

Next, the frozen food is seated on the upper surface of the top plate 360 exposed through the inlet 110 of the case 100 along the conveyor.

Thereafter, the upper plate 360 is returned to the inside of the chamber 300 by the control panel.

Next, the cooking apparatus 200 heats the frozen food by irradiating microwaves to the frozen food seated on the top plate 360.

At this time, the electromagnetic wave is irradiated to the frozen food through the electromagnetic hole (311a, 312a) formed in the upper panel 311 and the lower panel 312 of the chamber 300.
Here, the electromagnetic wave irradiated from the cooking apparatus 200 installed in the lower portion is to pass through the lower plate 340 and the upper plate 360 to heat the frozen food placed on the upper plate 360, the lower plate 340 and The upper plate 360 is not particularly limited as long as it is a material that transmits electromagnetic waves, but generally, a plastic material widely used in a microwave oven is preferable, and the principle itself of heating frozen food by electromagnetic waves irradiated from the cooking apparatus 200 is used. As it is assumed that the same as a conventional microwave oven, it is too natural that the inside of the chamber should be shielded while the electromagnetic wave is irradiated, so that an additional description thereof will be omitted.

In this case, the microwave irradiation time of the cooking apparatus 200 is controlled by the cooking time of the memory unit.

Thereafter, when cooking is completed, the control panel recognizes this and discharges the frozen food through the discharge port 120 of the case 100.

At this time, the control panel rotates the motor 370 in the opposite direction to the above direction, that is, the direction opposite to the direction in which the upper plate 360 is rotated to pull out the inlet 110 of the case 100. In addition, the top plate 360 discharges the top plate 360 through the discharge port 120 of the case 100 in the same manner as the top plate 360 was drawn out through the inlet 110 of the case 100.

Thereafter, the user ingests the cooked frozen food, and the top plate 360 is returned to the inside of the chamber 300 by the control panel.

As described above, due to the rotation of the plate pinion 350 in the process of transferring the lower plate 340, the upper plate 360, as well as the transport distance of the lower plate 340, the rotation distance of the plate pinion 350 As much as it can be transported.

Accordingly, the length of the fixed rack 320 installed in the direction of the entrance 300a of the chamber 300 can be reduced, so that an effect of reducing the size of the chamber 300 can be obtained.
