Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a dew condensation prevention heater that prevents and removes condensation from adhering to pachinko balls, for example.

Conventional Technology In recent years, pachinko machines have become more popular year by year because they are simple and easy to play, and anyone can enjoy them, and new models have been developed based on the ingenuity of the industry.

The conventional pachinko machine as described above will be explained below with reference to the drawings.

FIG. 3 shows an example of a conventional pachinko machine.

In FIG. 3, 1 is a pachinko ball, 2 is a lift, 3 is a supply distribution bucket, 4 is a pachinko machine, 5 is a supply pipe, and e is a collection area. The supply distribution tub 3 is installed with an incline (slanted to the right in the drawing) and is connected to the lift 2 (this connection part is referred to as the entrance of the supply distribution tub) and the supply vibro connected to each pachinko machine 4 (three machines in the drawing). It is.

The operation of the pachinko machine configured as described above will be explained below. First, pachinko balls 1 that have been washed, dried, and treated with oil (not shown in the drawing) are collected at a collection site 6 and transported by a lift 2 to a supply distribution bucket 3.

Since the supply distribution tub 3 has a slope, the pachinko balls 1 pass through the supply pipe 5 under their own weight and are supplied to the pachinko machine 4.

Problems to be Solved by the Invention However, the above configuration has the following drawbacks.

(1) When heating is turned on in winter, the room heats up first due to differences in heat capacity and thermal conductivity between the room and the pachinko machine.
Condensation occurs on pachinko machines, especially on pachinko balls and supplies.

(2) During the rainy season, condensation occurs due to humidity.

For this reason, the condition of the device changes slightly, making it difficult to control the pachinko balls. There were problems like those mentioned above. SUMMARY OF THE INVENTION In view of the above drawbacks, it is an object of the present invention to provide a dew condensation prevention heater that prevents and removes dew condensation from adhering to pachinko balls and the like.

Means for Solving the Problems To achieve this objective, the anti-condensation heater of the present invention has the following features:
A hot air heater consisting of a heating element and a blower is installed at the entrance of the supply distribution tube to blow hot air into the supply distribution tub, and a duct is connected from the connection between the supply distribution and the pipe to the hot air heater to blow hot air. The configuration is such that hot air is circulated to the heater.

Function: With this configuration, the air warmed by the heating element is forcibly sent to the supply distribution by the blower, so dew condensation can be removed and prevented.3 Furthermore, the supply distribution and hot air heater are Since they are connected by a duct, the air warmed by the hot air heater can be used again, making it possible to efficiently remove and prevent condensation.

EXAMPLES Hereinafter, examples of the present invention will be described with reference to the drawings.

FIG. 1 shows a hot air heater of a dew condensation prevention heater according to an embodiment of the present invention. In Figure 1, 7 is the wind tunnel, 8
1 is a blower, and 9 is a constant temperature heating element of the Monika type made of a positive temperature coefficient thermistor element. Lead wires (not shown in the drawing) for supplying voltage are connected to the blower 8 and the constant temperature heating element, respectively.

FIG. 2 shows the main parts of the dew condensation prevention heater of the present invention. In FIG. 2, 1o is the hot air heater shown in FIG. 1, which is connected to the hot air heater 10 from the junction between the upper part 3 of the inlet of the supply distribution tub 30 and the supply pipe 5, and the supply pipe 5 is It is connected to a pachinko machine (omitted in the drawing). In the figure, 3a, 3b, and 3c indicate measurement positions for checking the dry state, and arrows indicate the direction of flow of hot air. In this way, the condensation prevention heater installed in the Guchinko device was placed in a constant temperature room with a temperature of 26 degrees Celsius and a humidity of 70%.
100VAC is applied to the constant temperature heating element 9 of the hot air heater 1o to make the power 1800W, and 100VAC is applied to the blower 8.
C is applied and the air volume is set to 3nl for 1 minute, pachinko ball 1
After being cooled at a temperature of -16° C. for 2 hours, the sample was immediately placed in the supply arrangement 3 to generate dew condensation on its surface, and its dry state was examined.

In order to see the effects of the present invention, we compared the results with those when the pachinko ball 1 was dried under natural conditions (without the hot air heater 10 and duct 11) to dry the condensation generated on the pachinko ball 1 under the above conditions. Shown in the table.

As described above, according to this embodiment, it took 10 to 14 minutes to dry the dew condensation generated on pachinko balls, whereas the conventional method required 4 to 47 minutes, and the effect was great. Met.

The reason why such an effect was obtained in the present invention is (1)
The drying effect (drying time) is large because hot air is forced into the supply distribution tub using a hot air heater.

(2) Great drying effect due to the use of circulating warm air.

In the example, explanation was given as removing condensation when it occurs on a pachinko ball, but even when the dew condensation prevention heater was activated from the beginning to prevent condensation, the effect was excellent. Furthermore, in the example, a harmonica-type constant temperature heating element was used as the heat source, but in order to achieve the same purpose, a constant temperature heating element of the No-nekam type, a positive temperature coefficient thermistor element and fins, a sheathed heater, a corramid bulb, etc. It goes without saying that the electric power and the size of the airflow duct can be selected depending on the size of the pachinko machine to be installed.

Effects of the Invention As described above, the present invention provides a hot air heater consisting of a heating element and a blower at the inlet of the supply distribution tub to forcibly send hot air.
By connecting a duct from the supply distribution tub and pipe connection to the hot air heater to circulate hot air, condensation can be prevented and removed, and its practical effects are impressive.
