Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for a motor to be mounted inside an outer box of a home appliance such as a clothes dryer or a washing machine.

As a method for mounting such a motor, it is a known technique to interpose vibration-proof rubber at the mounting portion in order to prevent vibrations and noise caused by the motor from being transmitted to the outer box.

Figure 1 shows an example of this.Motor 1
The upper and lower sides of the support protrusion 3 formed on the support plate 2 are sandwiched between two anti-vibration rubbers 4 and 5, and the outer sides of the protrusion 3 and anti-vibration rubbers 4 and 5 are formed into a metal frame having a substantially U-shaped cross section. The edges of the frame body 6 are bent outward at right angles to form flanges 6A and 6B.
is screwed to a motor mounting plate 8 which is screwed to a metal bottom plate 7 of the outer box.

In the conventional example above, there are anti-vibration rubbers on the top and bottom of the motor support, and the entire anti-vibration rubber is pressed by the frame, so the vibration-proofing and sound-proofing effects are good, but since it is fixed with screws, It takes time and effort to do so, and if the screws are not tightened evenly, the two upper and lower vibration isolating rubbers may become misaligned with each other.

The purpose of the present invention is to solve the above-mentioned disadvantages of the conventional example, and to reduce the number of items and facilitate assembly.
This provides a motor mounting structure that is structurally reliable.

According to the present invention, this purpose is to interpose vibration isolating rubber above and below a protruding piece formed on the support plate of the motor, cover the outer side of the protruding piece and the vibration isolating rubber with a frame, and attach the lower end of the frame to the motor mounting base. In a structure in which the motor is mounted inside the outer box of the equipment by fixing it to the outer box of the equipment, two thick pieces with a gap between them are connected by a column as vibration-proof rubber, and the vibration-proof rubber is formed on the protruding piece of the support plate. Insert the column into the notch, attach the vibration isolating rubber to the protruding piece, cover the outside of the protruding piece and the vibration isolating rubber with a frame body having a U-shaped cross section, and attach the hook locking part formed at the lower end of the frame body.
This is accomplished by hooking it onto the locking part of the motor mount that is integrally molded into the synthetic resin bottom plate of the device.

According to the configuration of the present invention, since there is only one vibration isolating rubber, there is no mutual misalignment of the vibration isolating rubbers, and since the frame is simply hooked on the motor mounting base and no corner screws are required, it can be used as a tool. Installation work can be easily done by hand.

Hereinafter, embodiments will be described in detail with respect to FIG. 2 and subsequent figures. Note that the same reference numerals are used for the same elements as in FIG.

First, referring to FIG. 4, the vibration isolating rubber 10 used in the present invention will be explained.

The anti-vibration rubber 10 is a thick piece 1 consisting of two rectangular parallelepipeds.
The mutual gap 14 between the thick pieces 12 and 13 is connected by a cylindrical body 15, and cylindrical protrusions 16 and 17 are made to protrude from the upper and lower ends of the thick pieces 12 and 13 so as to be an extension of the cylindrical body 15. The end protrudes downward. All of these are integrally molded from synthetic rubber.

Figure 2 is a longitudinal sectional view showing the overall structure of the present invention.
A supporting protrusion 3 having a fitting notch 3A in the center as shown in FIG. 3 is provided on the supporting plate 2 at the lower part of the motor 1, projecting at right angles. Upper flanges 3B are formed by bending at the left and right ends of the supporting protrusion 3.

When the cylindrical body 15 of the vibration isolating rubber 10 is inserted into the notch 3A of the support protrusion 3, the thick pieces 12 and 13 are located above and below the protrusion 3, and are protrusions formed on the protrusion 3. The protruding piece 3 is forcibly inserted into the gap 14 of the vibration isolating rubber 10 so that the upper flange 3B bites into the thick piece 12, and the anti-vibration rubber 10 and the protruding piece 3 are reliably connected and will not separate due to slight vibration. .

In the figure, reference numeral 18 indicates a motor mounting base that is integrally molded on the synthetic resin bottom plate 19 of the outer box of the home appliance.
The lower cylindrical projection 1 of the vibration isolating rubber 10 is inserted into the through hole 8.
7 and place the motor 1 on the mounting base 18.

Next, the outside of the anti-vibration rubber 10 is covered with a metal frame 20 having a U-shaped cross section, the upper cylindrical projection 16 of the anti-vibration rubber 10 is protruded from a through hole provided on the upper surface of the frame 20, and the lower end of the frame 20 is The motor 1 is securely fixed on the mount 18 by hooking the hook latching portion 21 formed of a through hole into the latching protrusion 22 protruding from the mount 18. In addition, in that case, frame 2
0 has a spring effect and presses the vibration isolating rubber 10 and the supporting protrusion 3 against the surface of the mounting base 18,
The above connections will not loosen due to vibrations.

Further, in order to remove the motor 1 from the mounting base 18 for repair or inspection, it is sufficient to simply release the hooking and locking of the frame body 20.

As described above, the motor mounting structure for home appliances of the present invention eliminates the need for screws and allows the motor to be mounted on the bottom plate of a clothes dryer, washing machine, etc. using anti-vibration rubber. The work efficiency during assembly and disassembly is good because all you need to do is hook it up, and it is economical because the number of parts is small, and it is structurally reliable because the anti-vibration rubber does not get stuck due to the vibration of the motor. This is sufficient.
