JPH049576A - Dew receiver for vending machine - Google Patents

Abstract

PURPOSE:To improve the structure of a dew receiver so that it may not spill over even when a door is opened by installing a shutter which acts so as to shield a water drain port when an insulation door is opened and to release the shield of the port when the door is closed. CONSTITUTION:A shutter 15 is pulled up to the right side by the action of a spring coil 19 when an insulation door 4 is open so that a water drain port 8 may be closed. Therefore, this construction prevents dew water from spilling over from a dew water receiver 7 even when the door 4 is open. Then, if an attempt is made to close the door 4 from the aforesaid state, a projection piece 15A which forms the right side of the shutter 15 comes into contact with a vapor dish shoot 10, which forces the shutter 15 to slide left so that the shutter 15 may open the water drain port 8, thereby flowing out dew water from the water drain port 8 to the vapor dish shoot 10. When a further attempt is made to open the door 4 again, the shutter 15 will be full closed at the moment when the shutter 15 is separated from the vapor dish shoot 10.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a dew catcher for treating dew water adhering to a heat insulated door of a vending machine.

(B) Conventional technology Vending machines that store and sell products such as beverages and foods in a cool manner have their interiors cooled to a constant low temperature by a cooling device. The warehouse is surrounded by a heat insulating wall, and has a heat insulating door in front that can be opened and closed in order to replenish sales items. Further, in front of the heat insulating door, a main body door with a product outlet is generally configured to be openable and closable. In other words, an insulated door that is an internal door.

The main body door, which is an outer door, provides an insulated structure for storing the products so that it is not affected by the temperature of the outside world, and is designed to maintain a sufficient cooling state.

However, although the inside of the refrigerator is forcibly cooled by a cooling device, the dew point in the space between the heat insulating door and the main door is affected by fluorescent lights attached to the main door, control system equipment, etc. The temperature will rise and there will be a significant temperature difference from the inside temperature of the warehouse.

Since the space area is in a nearly windless state, dew tends to form on the entire surface of the heat insulating door.

Furthermore, the installation conditions for vending machines are strict, with temperatures exceeding 30 degrees Celsius and humidity of 80%. In such cases, a large amount of dew drips onto the front of the insulated door, causing the floor to warm. Furthermore, the insulated door naturally has an exit for the product, and since the insulation here is poor, dew condensation occurs even under normal installation conditions.

As a measure to treat dew water that occurs on such insulated doors,
As shown in Japanese Utility Model Publication No. 63-165480, a gutter for collecting and draining dew is provided along the lower end of the heat insulating door, and a dew receiving tray is arranged on the main body side in correspondence with this gutter.

In addition, FIGS. 3(a) and 3(b) show a vending machine having basically the same structure as the device disclosed in the above-mentioned publication. Figure 3 (
Figure 3(a) is a front view of the vending machine with the main body door open and the exposure tray mainly showing the device, and Figure 3(b) is a schematic side sectional view of the vending machine with the exposure tray mainly showing the device. In each figure, 1 is the main body of the vending machine, and 2 is a main body door which can be opened and closed at the front thereof, and is provided with a product outlet (not shown).

A product storage 5 is formed inside the main body 1 and is surrounded by a heat insulating wall 3 and has a heat insulating door 4 at the front opening that can be opened and closed. is stored. The inside of the warehouse 5 is cooled by a device (not shown) comprising a compressor, a condenser, an evaporator, and the like.

Further, the interior of the warehouse 5 generally has columns separated by parts type, and corresponding sales product outlets 6, 6.

Reference numeral 7 denotes a dew water receptacle extending laterally along the lower end of the heat insulating door 3, and is shaped like a gutter and is inclined downward so as to collect the dew water in one place. A drainage hole 8 is provided at this lowest point. On the other hand, 9 is the main body 1
On the side 'J. The dew water from the drain hole 8 is received and evaporated into an evaporating dish, that is, a dew water receiving dish, and has an evaporating dish chute IO through which the dew water flows down, and also has an evaporating dish chute IO to allow the water in the dish 9 to permeate and perform a cooling cycle. An evaporation cloth 2 which is brought into contact with the refrigerant condensing pipe 11 to evaporate the refrigerant is provided. A high-temperature, high-pressure refrigerant discharged from the compressor flows through the refrigerant condensing pipe 11, and the heat of this refrigerant causes the evaporation cloth 1 to
It is evaporated from 2. Moreover, although the evaporation cloth 12 is supported in an upright state by the refrigerant condensation pipe 11, that is, the evaporation pipe, it is also possible to set it upright by using other suitable supporting materials.

(c) Problems to be solved by the invention However, since the heat insulating door is frequently opened and closed for product replenishment or maintenance, it is difficult to solve the problem as shown in the above publication and in Figures 3 (a) and (b). With conventional dew treatment equipment, when the door is opened, the gutter loses its correspondence with the dew pan, and due to the vibrations at that time, the n remaining in the gutter (adhered due to surface tension) The problem with dew condensation (currently in the current situation) is that it spills directly onto the floor etc. from the drain hole of the gutter.

The present invention has been made to solve the above-mentioned drawbacks, and has the object of 6 (2) to provide an improved dew pan that prevents dew from spilling even when the door is opened. Means for Solving the Problems The present invention eliminates dew water that condenses on the insulated door of a vending machine.
This automatic system collects dew water in a gutter-like water receptacle installed along the lower edge of the insulating door and extends laterally, and drains water from the drain hole provided in the dew water receptacle on the bracket to the dew water receptacle placed on the main body side. The vending machine is provided with a shutter that operates to cover the drain hole when the heat insulating door is opened and to open it when the heat insulating door is closed.

(E) Function When the heat insulating door is opened, the shutter operates to close the drain hole provided in the gutter-shaped dew water receiver, and the dew remaining in the dew water receiver does not spill out from the drain hole.

Also, when the door is closed, the shutter operates to open the drain hole. Then, the dew water tray and the dew pan on the main body side are also located in a corresponding relationship. Therefore, the dew that adheres to the heat insulating door is collected in the dew water receiver at the lower end of the door, and is drained from the drain hole into the dew catcher.

(F) Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings. 1st
The figure shows a first embodiment, in which a fixing metal fitting 16 into which a shutter 15 is slidably inserted is attached to the lower surface of a dew water receiver 7 attached to the lower end of a heat insulating door 4, and a protrusion of this fixing metal fitting 16 is shown. A bow tension coil spring 19 is suspended between the hook provided on the piece 16A and the hook provided on the end of the shutter 15, and this tension coil spring I9 is always
As shown in FIG. 1(a), the shutter 15 is pulled into the sliding groove 2o, and the shutter 15 acts to close the drainage hole 8 provided in the dew water receiver 7. Reference numeral 21 designates a through hole on the side of the fixture 16 that communicates with the drainage hole 8.

Then, when 10 closes the insulation door 4, the shutter 1
This is a fixed part on the main body 1 side that moves the shutter 15 against the tension coil spring 19 and out of the fixing fitting 16 as the shutter 15 is further closed. is applicable.

Therefore, with the above configuration, when the heat insulation door 4 is in the open state, the shutter 15 is pulled to the right side by the tension coil spring 19 as shown in FIG.
Drain hole 8 is blocked. Therefore, even when the door 4 is open, there is no need to worry about water spilling from the water receiver 7.

Next, when closing the door 4 from this state, at a certain position,
The protruding piece 15A on the right side of the shutter 15 hits the evaporating dish chute 10, and then the shutter 15 is pushed and slides to the left, the shutter 15 opens the drain hole 8, and the dew water is drained from the drain hole 8 to the evaporating dish chute. 10 (see the figure).

Then, when the door 4 is opened again from this state, the shutter 15 becomes fully closed at the moment it leaves the evaporating dish chute 10, resulting in the state shown in FIG. 4(b).

FIG. 2 shows another embodiment, in which a balance weight is used to open and close the shutter 24. That is, the shutter 24 equipped with a balance weight 25 is similarly supported by a pin 26 on a fixing metal fitting 16 at the lower part of the dew water receiver 7 so as to be swingable. The shutter 24 is always urged to rotate upward by a balance weight 25, and at that time, an elastic sealing material 27 attached to the shutter 24 closes the drain hole 8.

When the door 4 is closed from the state shown in FIG. 2(a), at a certain position the right side of the shutter 24 hits the two main body side fixed parts, in this embodiment the evaporating dish chute 10, and then the shutter 24 is pushed to the left. , gradually rotates around the pin 26 as a fulcrum, and when the door 4 is completely closed, the shutter 24 is fully opened, allowing dew water to flow out from the drainage hole 8 to the evaporation pan 9.

Then, when the door 4 is opened again from this state, the moment the shutter 24 leaves the evaporating dish chute 10, the balance weight 25 brings it into the state shown in FIG. 2a, completely closing the drain hole 8.

(G) Effects of the Invention As described above, according to the present invention, the drainage hole provided in the gutter-shaped dew water receiver attached to the lower end of the insulated door is covered when the insulated door is opened, and opened when the insulated door is closed. Since the door is equipped with a shutter that opens and closes, the mist will not spill out from the dew water pan when the door is opened, eliminating the risk of getting the floor wet.

In addition, drainage of dew water is ensured.
