In these cases, it is difficult for people to dry laundry outside. To meet these needs, various indoor drying devices are used. This indoor drying device is placed on the wall, ceiling, floor, window, etc. in the room, and is used as a support or fixed appliance. However, few devices actively remove moisture from the laundry. In the prior art, a cylindrical shell around a drying seat in a tube-sealed room is made, so that the wind sent from the air supply device comes out from the bottom of the cylindrical shell, thereby drying the laundry; The wind of the wind machine blows into the clothes, so that the arm that hangs the clothes is rotated by a wind-powered rotating indoor drying seat.

However, the indoor drying rack described in the above-mentioned public information uses a well-known indoor drying rack, which not only makes clothes dry indoors faster, but also has corresponding problems. That is, the outer periphery of the indoor drying seat is sealed in a cylindrical shape, so that the air blown from the air supply device comes out from the lower part of the cylinder. In this case, because it takes time and place to place when it is used, even if it is forced to blow air, because it is a structure that exhausts from the lower part of the cylinder, it is necessary to eliminate that the laundry cannot be dried uniformly and efficiently. Disadvantages. As for the indoor drying stand, if the hanging arm for hanging the laundry rotates smoothly, and the wind of the blower is blown into the laundry to make the rotating wind type rotating drying stand, then it is necessary to eliminate the following disadvantages . For example, in order to rotate the hanging arm of the laundry by wind, the laundry must be placed in a small balance, and the wind of the separate blower must be Blow to the central part of the laundry; Because of the structure that rotates in the horizontal direction, the stability of the indoor drying seat is not good, and there is a danger of overturning; In terms of rotation speed, the composition of the laundry and the blower must be evenly arranged OK, late is not effective, and soon it is afraid that the indoor drying stand will fall down.

The lower part of the motor 7 is connected to the pillar 2 or the foot connection part 1 1. A drying rack 3 is provided on the motor 7. A driving device 5 powered by a motor 7 is connected to the upper part of the foot 1 of the drying base and a lower motor connection part 71 1, and a support 2 and a drying rack 3 are connected to each other through a motor upper connection part 721 of the driving device 5. The drive unit 5 can also be built-in. We offer electric rotary dryers that feature drying racks 3 and / or pillars 2 with electricity.

At the contact portion between the motor housing 71 and the motor cover 72 of the built-in drive device 5, a bearing 8 is provided between the motor housing 71 as a fixed part and the motor cover 72 as a rotating part, that is, between the motor housing 71 and the motor cover 72. The bearing 8 is provided with 81 sets of steel balls which can bear the load. A bearing 8 is provided at a contact portion between the motor housing 7 1 and the motor cover 72 with the built-in drive device 5. It is also possible to use a grooved oil groove 82 on the motor housing 71, and the convex turning wheel of the motor cover 72 is buried in the oil groove 82 of the motor housing 7 1 to form a grooved bearing structure (see Fig. 4).

The motor housing 7 1 of the driving device 5 is provided with a power supply cut-off device 9 for detecting an abnormality of the body tilt, and a power supply cut-off device 9 for an abnormality may be provided in the pillar 2.

Foot 1 can be set to tripod, cross, or multi-leg, or it can be disc-shaped. Of course, it is also possible to use a micro switch-type or limit switch-type power cut-off device 9.

The original indoor drying seat used on the indoor floor is inserted into a leg 2 at the foot connecting part 11 of the foot 1 of the tripod, and the other part 2 is connected to the upper part of the leg 2 while fixing it. The holder 4 installs 3 parts of the drying rack. Based on this structure, we provide from a one-piece drying stand with only one post 2 to a drying stand with three posts 2, and provide 16 to

Umbrella-shaped drying rack with 24 ribs 3 1. Umbrella-shaped drying rack with clips at the ribs

3 1 and various umbrella-shaped drying racks equipped with a clothes hanger at the umbrella bone Drying seat.

A lower motor connection portion 71 1 connecting the support post 2 or the leg connection portion 1 1 is provided below the motor housing 71 of the fixed motor 7, and a connection drying rack 3 is provided above the motor cover 72 connected to the motor output shaft 73. The motor upper connection portion 721 which acts on the pillar 2. Except for the motor 7 and the pillars 2 and the feet 1 and the drying rack 3, most of them are made of plastics, especially weather-resistant PP resin for molding and assembly. Considering that indoor environments such as stoves are used in winter, it is best to use PP resin with good flame retardancy. In addition, use motor housing 71 and motor cover 72 with impact-resistant and rigid resins such as AB S resin and PA resin. .

In order to prevent water dripping from the top from entering the motor 7, the structure of the motor 7 to prevent water from entering is adopted. That is, the diameter of the motor cover 72 is larger than the diameter of the motor housing 71, and the surface of the motor cover 71 should be inclined downward toward the outer edge portion. . A hole is provided at the bottom of the motor housing 71 for the power cord 6 to pass through the lower connection portion 71 1 of the motor. The power cord 6 passes through the opening through the hole provided on the side of the pillar 2 or through the leg. The electric wires of the connecting portion 1 1 are guided to the outside of the body with an opening, and then connected to a household outlet through a plug of the power cord 6. For this type of power application equipment, it is best to incorporate an intermediate switch or timer switch with an overcurrent cutoff fuse. The hole for the power cord 6 at the bottom of the motor case 71 serves as an air hole for the heat dissipation of the motor 7, but it is more actively considered that it is better to provide a hole on the bottom of the motor case 71 and a bottom plate that contacts the bottom surface of the motor 7. Air holes, that is, other heat-dissipating parts such as the bottom surface of the motor 7 are provided with air holes communicating with the pillar 2; the bottom of the motor casing 71 is provided with air extraction holes; the top surface of the motor casing 71 is provided with a top hole; Or the air from the pillar 2 cools the motor 7.

When the drying rack part 3 is evenly filled with 1 KG-6KG of laundry, the electric rotary drying apparatus rotates at a constant speed of 6-20 rpm. Compared with the drying time when not rotating, it can be found that the drying time when rotating in a certain direction is only half. Please refer to Table 1. Table 1 Comparison of rotary drying time and non-rotating drying time (temperature 2 C, humidity 50%)

Twenty cotton towels were dehydrated in a dehydration pad, and then divided into ten test articles and photographs, and placed on a drying rack 3 for a drying test.

Test product: The product of this utility model has a rotation speed of 8.5 RPM.

Control: The original indoor drying stand does not rotate.

Based on the premise of using a household power supply, a small AC motor such as a commutator motor, a synchronous motor, an induction motor, and a servo motor is selected for the motor 7. However, the motor 7 may also need to operate in an unmanned room for a long time (more than 6 hours), and then What obstacles might come down. Therefore, it is necessary to assume that even if the output shaft of the motor is not restrained by the outside, it will not reach above the specified temperature, and will run gently and stably, so that the motor can load a load of 1 -6KG at a speed of 6-20 rpm The motor 7 is selected for operation and the reduction gear 74 is selected so that the bearing 8 of the motor output shaft 73 can withstand the load.

The above-mentioned driving device 5 may be built into the lower part of the drying rack 3 of the drying appliance (FIG. 8 showing the installation state), or may be built into the upper part of the foot 1 of the indoor drying appliance (FIG. 9 showing the installation state). What position is limited. Similarly, the dryer is also made upside down, remove the tripod, increase the ceiling installation site, and then become a hanging product. For example, a small induction motor with a reduction motor and an installation size of 70mm X high with a rated voltage of 100 volts, 60 revolutions, a current consumption of 10W, a gear head integrated type, a rotation speed of 10 revolutions per minute, and an oil bearing A 100 mm motor 7 is incorporated into the driving device, and a direct load is hung on the output shaft 73 to rotate the pillar 2 and the drying rack 3.

The driving device of another electric rotary drying device according to the present invention is 2, the steel ball 8 1 is evenly embedded with the upper outer peripheral portion of the motor housing 71 as a fixed portion, and the bottom outer peripheral portion of the motor cover 72 is inserted into the output shaft 73 to cover the upper surface of the steel ball 8 1. The bearing 8 is fixed to the motor cover 72 with the bearing part fixture 83, and the bearing 8 is not detached. As shown in the enlarged view of the bearing 8 in FIG. 3, the steel ball 8 1 is buried in the motor housing 71. In order to achieve better durability, it is necessary to use a ball on the bearing 8. Alternatively, as shown in another enlarged view of the bearing 8 in FIG. 4, the bearing 8 is embedded in the oil groove 82 of the motor housing 7 1 by using a convex rotating wheel of the motor cover 72.

With this structure, even if the drying rack 3 fixed to the motor upper connecting portion 72 1 has an uneven load, it will not cause an oblique load on the motor output shaft 73. The structure in which the load is distributed by the bearing 8 allows the drying rack to rotate smoothly, which can reduce the load on the output shaft 73 of the motor 7. As a result, the motor 7 can be smaller and consume less current.

As another example, we assembled a small AC synchronous motor with a built-in reduction gear and a size of 50mm X with a rated voltage of 100V, 60HZ, a power consumption of 6W, a speed of 7.9RPM, and an oil-containing bearing. The H37mm motor makes the motor output shaft 73 not to bear the vertical load, but uses a wide bearing 8 to bear the vertical load, so that the pillar 2 and the drying rack 3 rotate.

When the electric rotary indoor drying appliance is used, the body may be tilted or turned down due to some external force. When the drying rack 3 is fixed and the motor 7 is loaded with a load, the current supplied to the motor 7 will increase. The fever of 7 will also increase. This has been confirmed in tests. (Please refer to Table 2)

Table 2 Comparison of motor overheating characteristics Test temperature 40 Humidity 50%

Installing small AC with reduction gear on electric rotary indoor drying equipment Synchronous motor (rated voltage 100V, 60Hz, power consumption 6W) was tested.

Test product: No load, normal operation Speed is 9.8RPM Reference product: Load applied to stop and stop

That is, if a load is placed on the motor during a turn, the current will increase rapidly, so a current breaker is used as the power cut-off device 9 during the turn; and because the temperature of the motor will rise, a bi-metal current cut-off device is also used. Power cut-off device 9 when turning over. In addition, as a safety device, the timer can be connected to the power line, and a fuse is also built in.
