TECHNICAL FIELD OF THE INVENTION
The present invention relates to a technique for treating drain water generated in a refrigerator in a vending machine that cools and sells products such as canned beverages.
[0002]
[Prior art]
Vending machines that cool and sell products such as canned beverages are widely used, and generally, several types of products are sold by one vending machine. In this vending machine, a plurality of heat-insulating chambers are formed in a refrigerator, a cooler is provided in each of the heat-insulating chambers, and a product rack in the heat-insulating chamber accommodates different products. In this way, a product cooled by a customer's purchasing operation from a predetermined product rack is sent to a product outlet on the front side, so that the customer's request can be met.
[0003]
In the adiabatic room, drain water is generated due to condensation of water vapor in the outside air that has entered when the product is refilled, or water droplets attached to the product. The drain water forms a refrigeration cycle together with the cooler, and is guided to an evaporating dish installed adjacent to a condensing unit arranged in a machine room formed below the inside of the refrigerator, where the drain water is evaporated. Thus, each of the heat insulation chambers is provided with a drain treatment device shown in FIG. 4 for sending drain water to the evaporating dish. In FIG. 4, reference numeral 1 denotes a heat-insulating chamber formed in a refrigerator, and 2 denotes a bottom plate of the heat-insulating chamber. The bottom plate 2 has an upper surface inclined in a mortar shape, and a drain port 2a is provided downward at the lowermost portion. Reference numeral 3 denotes a drain treatment device, a drain receiver 4 having an upper surface opening 41 facing the drain port 2a and having a drain port 42 at a lower end of a cylindrical portion protruding below the bottom plate 2, and a base end portion 51 having a drain port 42. And a hose 5 whose distal end extends to the above-mentioned evaporating dish. The hose 5 is laid so that a portion close to the base end is largely bent downward, and drain water is always stored therein to form a trap 6. Reference numeral 52 denotes a hanging metal fitting for supporting the hose 5 on the bottom plate 2. The above-mentioned plurality of heat-insulating chambers 2 are provided with the drain treatment devices 3 respectively. The machine chambers are provided with hoses 5 guided from the respective heat-insulating chambers. The drain water generated in each of the heat insulating chambers is collected in the respective drain receivers 4, sent to the evaporating dishes via the respective hoses 5 and the traps 6, and subjected to the evaporating process in the evaporating dishes.
[0004]
[Problems to be solved by the invention]
By the way, the vending machine requires extra care for installation of the hose 5 for forming the trap 6 with the hose 5 and is troublesome. Further, since a large number of hoses 5 are laid in the machine room below the bottom plate 2, the machine room becomes complicated and a large room space is required. Further, the connection and piping work of the hose 5 must be performed for each of the large number of drain receivers 4, and there are many disadvantages such as an increase in the number of assembling steps of the vending machine.
[0005]
SUMMARY OF THE INVENTION It is an object of the present invention to provide a vending machine having a drain processing apparatus which solves the above-mentioned difficulties and has a very rational configuration.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, according to the present invention, in a vending machine in which a plurality of heat-insulating chambers are formed in a refrigerator, and which cools and sells a product accommodated in each heat-insulating chamber, a bottom plate of each heat-insulating chamber is provided. At the lower part, a drain receiver with a trap for collecting drain water generated in the heat insulating chamber and discharging the drain water to the outside of the heat insulating chamber is installed, and the drain water discharged from the drain port of each of the drain receivers is received and guided to an evaporation treatment container. it is assumed that the provision of the gutter.
[0007]
According to the present invention, since traps are formed in the drain receptacles, work and attention for forming the traps are not required, and drain water from each drain receptacle is collected in one gutter and is collected in the evaporating dish. Since sending, many hoses are eliminated. Therefore, the inside of the machine room is simplified and the space is small.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
FIGS. 1 to 3 show a first embodiment of the present invention, and the same reference numerals as those in FIG. 4 denote the same or similar parts. In FIG. 1 to FIG. 3, the drain receiver 4A having the upper surface opening 41 facing the drain port 2a and having the drain port 43 has the drain port 43 higher than the bottom plate of the drain receiver 4A and lower than the height of the drain port 2a. And a trap 6A formed by providing a partition wall 6a extending to the inlet side and the outlet side of the drain water, and formed by plastic molding. The drain receivers 4A are provided for each of the heat insulating chambers 2, and are mounted below the bottom plate 2 so that the drain holes 43 of the drain receivers 4A are aligned. In the drain receiver 4A, a flange 40f and a claw 40p are provided on the outer peripheral surface of the cylindrical portion 40 having the opening 41 on the upper surface, while the insertion hole of the cylindrical portion 40 opened on the outer plate of the bottom plate 2 of the heat insulation chamber is provided. A notch 2n through which the claw 40p can be inserted is provided at the edge of the hole, and these constitute a bayonet-type mounting mechanism. Reference numeral 44 denotes a reinforcing rib which also serves as a handle of the drain receiver 4A. The drain receiver 4A has the rib 44 and is inserted into the hole of the bottom plate 2 and rotated by the bayonet mounting mechanism. Work is easily performed without the need for tools. 7 is a gutter provided so that each of the drainage ports 43 faces the upper surface. The gutter 7 is fixed to a component member of a machine room by a hook 71 provided at an upstream end and a projection 72 at a downstream end. A drain port 73 facing the evaporating dish is opened at the downstream end.
[0009]
In the configuration described above, in the vending machine, drain water generated in the heat insulating chamber 1 is collected at the bottom and flows to the drain receiver 4A through the drain port 2a. The drain receiver 4A allows the drain water to flow into the gutter 7 and the trap 6A constantly collects the drain water to a certain level at the bottom of the drain receiver 4A, so that outside air and pests are insulated through the drain water drain passage. The intrusion into the room 1 is prevented. The gutter 7 collects the drain water from the drain receiver 4A of each of the heat insulating chambers, and causes the drain water 73 to flow out to the evaporating dish. As described above, the drain treatment device 3 treats the drain water generated in each of the heat insulation chambers without any trouble, does not require any trouble in forming the trap in its installation, and has one gutter 7 in the machine room. Since the drain water can be sent to the evaporating dish, the installation work is simplified, the machine room is simplified, and the space in the room can be reduced.
