(57) [Summary] (with modifications) [Purpose] To prevent the intermediate filter from bending or coming off and increasing the amount of dust contained in the exhaust air when a heavy foreign object enters the intermediate filter. Provide vacuum cleaners. [Structure] It has a main body 1, an upper main body, an electric blower, and an intermediate filter 3, and the intermediate filter 3 is sandwiched between the main body 1 and the upper main body, and the ribs are sandwiched between the main body 1 and the upper main body 2. By tilting the main body 1, a horizontal portion 16 and a stepped portion 17 are formed in the tip shape of the ribs of the main body 1 to securely fix the intermediate filter 3, prevent it from deflecting when foreign matter enters, and prevent it from coming off. To provide a vacuum cleaner with stable performance without any problems.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention is applicable to intermediate filters for vacuum cleaners used in general homes and commercial use. It is related to

0002

[Conventional technology]

Conventionally, this type of vacuum cleaner has been constructed as shown in FIG.

0003 To explain the structure, an intermediate filter 3 is sandwiched horizontally between a main body 1 and an upper main body 2. It is structured in a detailed manner.

0004 When the electric blower 4 moves, the exhaust gas passes through the intermediate filter 3 and is discharged to the top. be done.

[0005] The flow of exhaust gas is shown by arrows.

[0006]

[Problem that the idea aims to solve]

However, with this configuration, the main filter 5 becomes dirty and cannot be replaced. If the main filter 5 is not included, there may be things inside the main filter that would naturally not fit into the main filter. enters and stops at intermediate filter 3.

[0007] If the object inside is heavy and falls into the center of the intermediate filter 3, the intermediate filter The router 3 is flexed and stretched, and a large amount of dust gets on the exhaust gas and is discharged.

[0008] Also, if the deflection is large, the intermediate part that is stopped by the ribs of main body 1 and upper main body 2 The filter 3 will shift and come off, further increasing the leakage of dust.

[0009]

[Means to solve the problem] In order to achieve the above object, the present invention includes a main body, an upper main body, an electric blower, In a vacuum cleaner having an intermediate filter, the intermediate filter is connected to the main body and the upper By slanting the ribs that are sandwiched between the main body of the part, even when heavy objects are inserted, the intermediate The filter is designed to be hard to bend and hard to come off.

0010

[Effect]

The vacuum cleaner of this invention consists of a main body, an upper main body, an electric blower, and an intermediate filter. having a configuration in which the intermediate filter is sandwiched between the main body and the upper main body, By slanting the ribs sandwiched between the main body and the upper main body, the main body By making the tip of the rib horizontal and lowering the following rib one step, the intermediate fill is created. It securely fixes the router and prevents the intermediate filter from bending when foreign matter gets inside. To provide a vacuum cleaner that does not come off and has stable performance.

[0011]

【Example】

An embodiment of the present invention will be described below with reference to FIGS. 1 to 7.

0012 From FIG. 1, in FIG. 7, 1 is the main body, 2 is the upper main body, and is fixed by the boss 6. ing.

[0013] 3 is an intermediate filter. 4 is an electric blower, and 5 is a main filter.

[0014] 7 is an electric cord, and 8 is a roller. 9 is a case surrounding the electric blower 4.

[0015] 10 is a cord reel support body, 11 is holding down the main filter 5 It is a filter case that can be rotated around its axis.

[0016] 12 and 13 are ribs protruding from the main body 1, and the ribs 1 formed on the upper main body 2 It is designed to match 4.15.

[0017] In the above configuration, the intermediate filter 3 has two cross-shaped notches. It is designed to fit the boss 6.

[0018] Also, the intermediate filter 3 should fit the boss 6 no matter how it is turned from front to back or left or right. It has become.

[0019] In the above configuration, when the power cord 3 is plugged into the outlet and the operation is started, When the electric blower 4 (hidden in the case 9 in the diagram) moves, the electric blower 4 The exhaust gas flows as shown by the arrow, and passes through the intermediate filter 3 and the main filter. 5 and is ejected from the machine.

[0020] If there is no main filter 5, heavy objects will fall from the exhaust port and the intermediate filter - 3, the intermediate filter 5 has an inclined surface, so heavy objects that have entered the filter falls along the slope and sandwiches the intermediate filter 5 between the ribs of the main body 1 and the upper main body 2. Calm down to where you are.

[0021] This location is where the intermediate filter 3 is sandwiched, so it is near the support point. The least amount of deflection.

[0022] Also, the part where the intermediate filter 3 is sandwiched between the main body 1 and the upper main body 2 has an inclined surface. Because of this, the area for sandwiching the intermediate filter 3 increases, making it difficult to remove it. .

[0023] In addition, by tilting the intermediate filter 3, the intermediate filter 3 can be The increased surface area reduces exhaust pressure drop and allows for smooth flow.

[0024] In addition, the increased surface area of the intermediate filter 3 may cause the intermediate filter 3 to become dirty. It's difficult.

[0025] Furthermore, by tilting the intermediate filter 3, exhaust noise can be reduced. By increasing the distance through the intermediate filter 3, it has the effect of reducing exhaust noise. There is fruit.

[0026] An embodiment of what is described in Section 2 is shown in FIGS. 4 and 5. To explain the figure, the tip of the rib 12 at the rear of the main body 1 that sandwiches the intermediate filter 3 The shape is formed by a horizontal portion 16 and a stepped portion 17.

[0027] This prevents the intermediate filter 3 from being tilted diagonally when sandwiching and fixing it. The rollers and horizontal corners make the fixation more secure.

[0028] Also, suppose that the shape of the intermediate filter 3 was made slightly larger due to dimensional tolerances. Also, because of the lowered part 17, the intermediate filter 3 can be easily inserted. be able to.

[0029]

[Effect of the idea]

As described above, the vacuum cleaner of the present invention includes a main body, an upper main body, an electric blower, and a middle part. an intermediate filter, and the intermediate filter is sandwiched between the main body and the upper main body. In the configuration, by slanting the sandwiching ribs of the main body and the upper main body, , the end of the rib of the main body is made horizontal, and the rib following it is lowered by one step. This will securely fix the intermediate filter and prevent it from sagging if foreign matter gets into the intermediate filter. It prevents scratches, does not come off, reduces exhaust pressure loss, is stain resistant, and is soundproof. An effective intermediate filter can be provided.
