The present invention relates to a power saving device of the vending machine of the present invention, in particular, to display the product when it is sold out and to stop the operation of the cold heating device by cutting off the power of the compressor and the heater. It relates to a power saving device.

Conventional vending machines have a cooling device and a heating device for cooling the built-in goods to provide cool and hot drinks for the unique purpose of convenient service to the customer.

In addition, the cooling and heating device that cools and heats the built-in products consumes a lot of power, and thus, many wires for power connection are separately installed, and the power consumption is very large and requires a lot of power.

As described above, a conventional vending machine that installs a cooling device, a heating device, or a cold device, a heating device, and sells a product of a cool drink or a hot drink is sold out of the product once filled and sold out. It takes a long time to refill, and mainly checks whether or not the product is sold out once a day, causing a waste of continuous useless power at night regardless of the presence or absence of the product.

That is, even though there are no products to be sold because the products mounted on the vending machine are sold out, there has been a problem of consuming unnecessary power for a long time by continuously driving the cooling device and the heating device.

Accordingly, an object of the present invention is to provide a power saving circuit of a vending machine that displays the same time when the products to be sold in the vending machine are sold out, and simultaneously stops the operation of the cooling device and the heating device.

In order to achieve the above object, the present invention selects the identification of the degree of input and processes the amount of money and at the same time the coin outputs the sales function signal, and when the coin is input when the fully sold out signal, the dynamic acceptor rejection signal (Coin Accepter Refusal Signal) In the power saving device of a vending machine having a coin mechanism (Coin Mechanism) for automatically returning the coin entered by generating a), input the signal output from the coin mechanism to output the product selection signal of each column by the selection key pressing And a selection switching means for outputting the product selection signal and the column sold-out state signal outputted by the selection switching in the switching means, each column sales relay means for exporting goods of each column, and whether or not there is a product in each column. A heat-dissipating unit which is turned off by outputting a signal for sold out of each column to the sales relay means and outputting a complete sold-out signal when the goods of each column are sold out completely; A means for interrupting the power input to the Z1 and the heating device load Z2 and outputting and displaying a completely sold out display signal, and being operated by the fully sold out signal from the means to stop the cooling and heating operation when the power is cut off. It consists of a chiller load (Z1) and a heater load (Z2).

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a power saving circuit diagram of a vending machine according to the present invention, which simultaneously sorts coins and processes the amount of money and simultaneously processes the amount of money outputting a sales function signal. Coin Mechanism (hereinafter referred to as C / M) 100 and, in gakyeol selection switch (SL _1, SL ₄₎ and, gakyeol selection switch (SL _1, ~SL ₄₎ to a switching operation by the selection by the respective input signal into a serial state output from the coin mechanism (100) It is excited by inputting selection signal and each column sold out status signal, and is turned on depending on the presence or absence of merchandise in each column and the sales relay (VRY _{1 to} VRY ₄ ) to drive the motor or solenoid and take out the product. Is sold off gakyeol first detection switch for outputting a signal gakyeol sold out by blocking the power supply of each column - and (S ₁ S _4), the first gakyeol sold sensing switch-on of the (S ₁ S _4). Cooling and heating operation are performed by the second row of the second sold out detection switch (S ' ₁ -S' ₄ ) and the second row of the second sold out detection switch (S ' ₁ -S' ₄ ) that interlocks and outputs a completely sold out status signal. A completely sold out operation relay (RYC) for outputting a status signal and a completely sold out condition signal, and a cooling device load (Z1) for performing cooling and heating operations respectively by an operating state signal outputted from the completely sold out operation relay (RYC); It is composed of a heating device load (Z2) and the lamp (L ₁ ) for inputting the output completely sold state signal to display the complete sold out state, Figure 2 is a flow chart of the first.

In the ecology where the power of the XY line is C / M (100) and the product (contents) in each column (AD), and the first column detection switch (S ₁ -S ₄ ) is on, The coin set in the C / M 100 is fed under the condition that the terminals 1'-4 'of (S' ₁ -S ' ₄ ) and the cooling device load Z1 are supplied to both ends of the heating device load Z2. Then, the terminal SN of the C / M 100 outputs the sales function signal to the terminal a of the column A selection switch SL ₁ .

At this time, when each row selection switch (SL ₁ -SL ₄ ) is not pressed, the series function is connected in series, and the selling function code inputted to the terminal (a) of the row A selection switch (SL ₁ ) is the row D selection switch (SL _4). Is input up to terminal (d).

On the other hand, the first sold-out detection switch (S ₁ -S ₄ ) in the column (AD) having the products sold in each row (AD) maintains the "on" state. When the power is turned on, the power signal is transferred to the array selling relay (VRY _1- VRY ₄ ). Outputs a signal that it is not sold out, and each of the second sold-out detection switch (S ' ₁ -S' ₄ ), if there is a product in one row of each row, the power signal of the sold out operation relay (RYC) and C / M (100) Input to the coin suppression reject signal terminal (ST).

Therefore, under the above operating state, the C / M 100 outputs the selling function signals through the terminal SN to the column select switches SL ₁ to SL ₄ . The user gakyeol selection switch (SL ₁ -SL ₄₎ of when "on" by pressing any switch, for example, A column selecting switch (SL ₁₎ is pressed when "on" sold gakyeol first detection switch ( S ₁ ) is "on" (goods "state"), so the column A sales relay (VRY ₁ ) is excited and the motor or solenoid (not shown) through the contacts (not shown) of the relay (VRY ₁ ). ), Etc., to export the goods contained in column A.

At this time, when there are no products in column A by many users 'choice, each column first sold out detection switch S ₁ and each column second sold out detection switch S' ₁ are interlocked and turned off at the same time. A column sold out signal is input to VRY ₁ ).

On the other hand, even though the products in column A are sold out, columns (B, C, D) are not sold out (B, C, D), so the column sales relays (VRY _2- VRY ₄ ) are the first sold out detection switches (SL ₁ -SL). ₄ ) is in the "on" state, so that the sales queue (VRY ₂ -VRY ₄ ) receives the product stock signals, while the C / M (100) accepts coins and the fully sold operation relay (RYC) is the second column. The magnetic contact point (RYC-a) of the fully sold operation relay (RYC) is kept on and cooled by maintaining the state of being excited by the "on" state of the diagnosis detecting switches (S ' ₁ -S' ₄ ). The heating device load (Z1) (Z2) is operated to maintain the cooling and heating operation.

Also gakyeol piece (A, B, C, D ) when both are sold to operate as the above-described heat and A gakyeol first sold detecting switch (S ₂ -S ₄₎ and said first gakyeol sold detecting switch (S ₂ -S ₄ The second detection switches S ' ₂ -S' ₄ interlocked with each other are also " off ".

Therefore, the power supply of the X-line is not input to the dynamic accept reject signal terminal ST and the fully sold operation relay RYC of the C / M 100, so that the excited state is released and the magnetic contact RYC-a is turned off. And the (RYC-b) is turned "on" to electrically shield the cooling, heating, and device loads (Z1) and Z2. (L ₁ ) is displayed to " inform "

That is, when the products of each column AD are sold out, the first and second sold out detection switches S ₁ -S ₄ (S ' ₁ -S' ₄ ) of each column are "off", so that the complete sold out operation relay (RYC) is of course. The power supply signal is also cut off to the dynamic upset rejection signal input terminal ST of the C / M 100, so that a completely sold-out operation relay (RYC) operates to cut off the power signal input to the cold / heating device load (Z1) (Z2). And, C / M (100) is automatically returned even if the coin set as a coin inlet of the vending machine.

Referring to the above-described operation with reference to the flow chart of Figure 2, when the power is input to operate the vending machine first, whether there is a product sold out whether the sold out detection switch (S _1- S ₄ ) of each row (S ' _1- S') ₄ ) If there is a product, it is possible to sell the product by inputting the power signal through the operation suppression signal terminal (ST) and the completely sold operation relay (RYC) of the C / M 100 so that the product can be sold at the same time. In order to cool or heat the contents in the state, the cooling device and the heating device are operated continuously, and when there is no product, the respective heat exhaustion detection switch (S ₁ -S ₄ ) (S ' ₁ -S' ₄ ) is off. The coin input rejection signal input terminal (ST) of the C / M 100 and the completely sold operation relay (RYC) are turned off and the coins are automatically returned. Cooling, heating operation Stop it.

Therefore, as described above, the present invention uses a simple circuit in a vending machine equipped with a cooling device and a heating device to display the product when it is sold out and simultaneously cool it. By cutting off the power supply to the heating device, unnecessary power loss can be prevented, which is a great advantage in the energy saving effect.
