Description

[Detailed Description of the Invention] The present invention relates to reinforcing support ribs for positioning an electric blower built into a main body case of a vacuum cleaner.

In conventional vacuum cleaners, an electric blower built into the main body case is supported by a support member installed inside the main body case.

However, since the support member is relatively weak in strength, if the main body case is dropped with the rear side down, the support member will not be able to withstand the impact load of the electric blower at the time of a collision, and the support member will break. There were problems with strength, such as:

The present invention was developed in view of the above points, and includes a rear opening of the rear case that houses an electric blower, a removable rear cover that closes the rear opening, and an inner surface of the rear cover that is attached to the rear case. The above-mentioned conventional problems are solved by forming reinforcing ribs that are integrally molded with the electric blower and limit rearward displacement of the positioning support ribs that position and support the electric blower.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 6. 1 is a dust collection case as a front case of a vacuum cleaner case with a built-in dust collector and has an approximately oval cross section, and 2 is a main body case as a rear case of the vacuum cleaner case having a rear opening at the rear end to collect dust. Case 1
It can be divided freely. 3 and 4 are a lower case and an upper case formed by connecting the main case 2 with screws, etc.; 5 is a removable rear cover that closes the rear opening of the main case 2; and 6a and 6b are the lower case 3 and the upper case, respectively. A partition rib integrally formed with the case 4 defines the interior of the main body case 2 into a chamber in which an electric blower 7 is disposed and a chamber in which a cord winding device 8 is disposed in parallel in the horizontal direction. Reference numerals 9 and 9a are positioning support ribs that position and support the electric blower 7 within the lower case 3, and are integrally formed with the lower case 3. The positioning rib 9a projects toward the rear opening of the main body case 2 and is integrally formed with another positioning rib 9. Reference numeral 10 indicates a support rib that positions and supports the electric blower 7 within the upper case 4 and is formed integrally with the upper case 4. Reference numeral 11 indicates a division formed by recessing the outer surface of the rear cover 5 inward and expanding the inner surface thereof. The handle 12 is a partition wall that forms a narrow space with the upper wall of the upper case 4 of the main body case 2, and is integrally formed with the rear cover 5. Reference numeral 13 denotes a cord entrance/exit for a power cord (not shown), and 14 denotes an L projecting from the inner surface of the rear cover 5 across the flat part and the bulging part.
The electric blower is provided on the rear cover so that the reinforcing ribs are substantially parallel to each other, and their leading edges are close to and opposite to the positioning support ribs 9, 9a of the electric blower 7, which are integrally formed on the lower case 3. Blower 7
This is provided to reinforce the positioning support ribs 9, 9a in order to prevent the positioning support ribs 9, 9a from being destroyed when the positioning support ribs 9, 9a try to move rearward. Reference numerals 15 indicate the reinforcing ribs 14 at positions close to each other on the opposing side and the opposite side of the reinforcing ribs 14;
A rib 16 is formed integrally with the inner surface of the rear cover 5 facing the other end, and is used for reinforcing ribs 14 and ribs 15 on both sides of the rib 15 in order to form a relay storage part having a storage opening on the inner surface of the rear cover 5. A rib 17 integrally formed on the inner surface of the rear cover 5 over the lower end is a relay inserted in the storage section and is used to control the electric blower 7.
Performs ON-OFF control. Then, with the rear cover 5 attached to the rear end opening of the main body case 2, the relay 17 abuts against the positioning support rib 9a and is fixed to the storage section. 18 is the exhaust port, 19 is the exhaust port 1
This is a filter provided in part 8.

In a vacuum cleaner having such a configuration, positioning support ribs 9, 9a, 1 for positioning and supporting the electric blower 7 are provided.
0 for the reinforcing rib formed integrally with the rear cover 5
4 protects the positioning support ribs 9, 9a, and 10 from the rear side, even if the main case 2 is dropped with the rear side down, the displacement of the positioning support ribs 9, 9a, and 10 due to the impact load of the electric blower 7 during a collision is at its elastic limit. The positioning support rib 9 connects to the reinforcing rib 14 before
Since the positioning support ribs 9, 9a, and 10 are supported by contacting with the support ribs 9, 9a, and 10 are prevented from being destroyed. Therefore, the vacuum cleaner itself will not be destroyed from within.

Furthermore, since the reinforcing ribs 14 have the functions of restricting the displacement of the positioning support ribs 9, 9a, and 10 and forming a relay accommodating portion for accommodating the relay 17, the structure is simplified.

As explained above, according to the present invention, in a vacuum cleaner with a built-in electric blower, a detachable rear cover is provided at the rear opening of the main body case, and the rear end of the electric blower is provided on the rear opening side of the main body case. A positioning support rib is provided for positioning the rear cover, and a reinforcing rib whose tip is close to the positioning support rib is provided on the surface of the rear cover facing the positioning support rib. Even in the case of a fall with the positioning support rib facing down, the backward displacement of the positioning support rib due to the impact load of the electric blower during a collision is limited because the positioning support rib contacts the reinforcing rib before reaching its elastic limit.
It is possible to provide a solid vacuum cleaner in which the positioning support ribs are not destroyed and the inside is not destroyed.
