Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a dryer for shoes such as sneakers.

(b) Prior Art An example of this type of shoe dryer is shown in Japanese Utility Model Publication No. 18877/1983. In this system, multiple shoe holding tubes are set up on a base, and each holding tube is equipped with a fan-based ventilation duct and a heater.If the amount of air blown and the amount of heating are constant, each holding tube has a certain amount of heat. It is designed to blow dry air. However, in this conventional example, due to variations in heaters, etc., the degree of dryness in each holding cylinder actually varies, and it is necessary to prepare ducts and heaters individually.

Therefore, the applicant proposed a shoe dryer with a simple structure in which heated air is distributed and supplied to a plurality of holding cylinders from a common air passage in Utility Application No. 171206/1983. However, although this product maintains a good mixing state of cold air and hot air through the ribs, the cold air and hot air tend to directly flow out into the drying room in the area facing the cold air opening or hot air opening. The amount of drying air sent to the holding cylinders near the hot air outlet varied greatly, and the quantity was sometimes smaller than that of the holding cylinders located further away.

(c) Problems to be solved by the invention The invention aims to improve the degree of mixing of cold air and hot air, and to distribute the air evenly from both the far and near holding cylinders.

(d) Means for solving the problem The solution according to the present invention is to partition the respective end faces of the adjacent drying room and ventilation room with end plates, and to surround the end plates with covers to create a box-shaped structure. A plurality of openings are provided in the end plate of the drying chamber, and shoe holding tubes protruding toward the other end are connected to the respective openings, and the end plate of the drying chamber is connected to the ventilation path. In addition, a cold air outlet and a hot air outlet facing the cover are provided adjacent to each other, and a rib is provided to protrude so as to partition the inside of the air passage into an air blowing chamber side and a drying chamber side over substantially the entire width, and this rib The portion facing the cold air port or the hot air port has a larger protrusion than other portions.

(E) Effect Cold air or hot air coming out of the cold air outlet or hot air outlet tries to move as it is to the drying room side in the air channel over the shortest distance, but its movement is blocked here by the rib and the large rise of this rib. , a turbulent flow is generated on the side of the ventilation chamber in the ventilation channel, flows to a relatively low and low resistance part of the rib, and from there exits to the drying chamber side of the ventilation channel. Therefore, the drying air is supplied to the holding tubes closer to the ribs and to the holding tubes farther away from the ribs with little difference.

(f) Embodiments Examples of the present invention will be described based on the drawings. 1

14... is a shoe holding tube formed by curving a steel plate, and the proximal opening 15 is fixed by welding or the like to the end plate 5a constituting the rear wall of the drying chamber 3, and the tube is connected to the air passage 5 so as to be connected to the front side. It stands out. And this holding cylinder 1
4... are symmetrically provided at four locations on the top, bottom, left and right of the rear surface, and the openings at the ends are cut off diagonally downward. Reference numerals 16 and 16 indicate holding rods each formed by bending a round rod into a U-shape, and are arranged on both sides of the inner surface of the holding tube 14 so that both legs are positioned above and below, so that children's shoes can be hung thereon. It is set as.

Reference numerals 17 and 18 denote a hot air opening (near the end) and a cold air opening (closer to the inside) provided on the end plate 5a toward the cover 5b in order to communicate the air passage 5 and the ventilation chamber 4.
Each opening has a vertically long rectangular shape, and is provided parallel to the center in the vertical direction.

A duct-shaped hot air passage 19 is provided on the side of the blowing chamber 4 of the hot air outlet 17, and the hot air passage 19 and the cold air outlet 18 are surrounded by a duct-shaped cold air passage 20, and this cold air passage 20 is connected to the fan. Casing 12
The hot air outlet 13 is directly opposed to the hot air passage 19 .

21... are three honeycomb-shaped heaters made of PTC elements arranged at equal intervals in the longitudinal direction in the hot air path 19, so that the center of the central heater 21C coincides with the center of the air outlet 13. A portion of the upper and lower heaters is arranged within the vertical dimension t of the air outlet 13. Reference numeral 22 denotes a rectifier plate made of a wire mesh or the like that is attached to the cold air outlet 20 and also serves as a filter. Then, the temperature of the dry air, which is a mixture of cold air and hot air, is increased by 30 degrees relative to the outside temperature.

On the other hand, 23... are ribs that protrude over substantially the entire length of the vertical dimension so as to vertically partition the inside of the air passage 5 near the base opening 15...
It is constructed by fixing one end surface of a plate material having an L-shaped cross section to the end plate 5a or cover 5b. Among these ribs 23..., the rib 23a that initially partitions the drying chamber 3 side and the ventilation chamber 4 side in the air passage 5 is provided on the cover 5b, and the central part of its tip is set to approximately the same size as the above-mentioned dimension t. A protruding piece 24 is further provided over the entire length. The degree of protrusion of this protruding piece 24 is such that it sufficiently overlaps the protruding end of the rib 23 in the next stage.

25 is a thermistor as a temperature detection element attached to the center of the rib 23b at the innermost part of the air passage beyond the holding cylinder 14, and the detected output voltage is compared with the reference output voltage by the comparator 26. , the comparator output is input to a microcomputer (hereinafter referred to as microcomputer) 27 as an operation control means. The microcomputer 27 is an input unit 28 for a start switch (coin switch if it is a coin type), door switch, etc.
In response to input signals from the thermistor 25 and the thermistor 25, the drive motor of the fan 11, an indicator lamp 29 indicating power on/off and operating status, heaters 21 and 21C arranged in a lower and central pair, and one heater on the upper side. The output signal is sent to 21 etc. to control the temperature etc. of the drying air.
In particular, the microcomputer 27 turns on one heater 21 several seconds after turning on a set of heaters 21 and 21C when turning on the heaters 21, and turns off all of them at the same time when turning off. The delay time when this is ON is 3
The quantile is the longest. Therefore, the rush current when turned on can be suppressed.

Next, the operation will be described. First, the lid 6 is opened, and up to four adult shoes and up to eight children's shoes are hooked onto the holding tubes 14, 16, and 16, respectively. Then, a start signal from the input section 28 energizes the drive motor of the fan 11 and the heater 21 . Then, the air from the fan 11 is heated by the heaters 21 and blown out as hot air from the hot air outlet 17 into the air passage 5, and at the same time passes through the cold air passage 20 without passing through the heaters 21. The cold air is blown out from the cold air outlet 18 into the air passage 5 as cold air. The cold air and hot air diffuse when they hit the inner surface of the cover 5b, but the ribs 23a protruding from the inner surface of the cover and the surrounding wall of the cover prevent them from flowing immediately toward the drying chamber, and they are temporarily mixed. Moreover, the projecting piece 24 prevents the water from flowing in the shortest distance toward the drying chamber. The drying air whose mixing has been promoted in this way is transferred to the projection piece 2.
4, go over the tip of the rib 23a from above and below, and head toward the drying chamber side. Then, it advances to the back along the upper and lower parts of the air passage 5, and in the meantime, the ribs 23 advance the mixing, and at the innermost part, it is turned over to the center, and from here, the base end openings 15... are opened in the respective holding cylinders 14... The air enters the air as drying air, which is 30 degrees higher than the outside temperature, and blows into the shoes, drying them from the inside. Thereafter, the moisture is discharged from the exhaust duct 10 to the outside of the machine.

Since the thermistor 25 detects the temperature of the dry air that has reached the innermost part, it can detect the temperature that is approximately the same as the temperature of the air that blows out from the holding cylinder 14.
Based on such accurate detection, the microcomputer 27 turns off the heater 21 when the temperature of the dry air rises to 55°C.
It turns on when the temperature drops to 48℃. This temperature range is
In this example, where the temperature can be increased by 30 degrees, the outside temperature is 18 degrees.
℃ to 25℃, and those using this type of heater, which has a large inrush current at low temperatures, have the effect of suppressing the inrush current and current consumption.

(g) Effects of the invention According to the invention, the cold air and hot air almost never pass through the air passage in the shortest distance, and the mixing condition is improved, so drying air is evenly supplied to each holding cylinder. It is possible to provide a shoe dryer with extremely high drying efficiency.
