Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electric vacuum cleaner in which a suction unit is connected to a suction machine body.

[0002]

[Problems to be solved by conventional techniques and devices]

 The suction part of a conventional electric vacuum cleaner has a connecting part in the center of the suction part, and since a suction hose is connected to this connecting part, the central part of the suction part near the suction hose has a strong suction force. It was weaker as it approached the part, and had the drawback that dust, dust, and sand from both ends were left behind.

Therefore, it is necessary to clean the remaining portion while changing the phase position, which is time-consuming and inefficient. The present invention solves the above drawbacks and provides an electric vacuum cleaner that can be cleaned quickly and efficiently.

[0004]

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

In an electric scavenger in which a suction section 2 for sucking dust through a suction hose 1 is connected to a suction machine body a, a plurality of partition walls 5 are provided between side plates 4 of a case 3 of the suction section 2 for suction. The part 2 is formed in three or more suction chambers 6a, 6b, 6c ... And each suction port 7 is provided below the suction chambers 6a, 6b, 6c. Is selected so that the average suction can be performed, and the total area of the suction ports 7 is set so as not to be too large compared with the cross-sectional area of the suction hose 1. It relates to an electric vacuum cleaner.

[0006]

[Action]

 When the suction unit 2 is moved by operating the suction unit a while abutting it on the floor surface, a plurality of partition walls 5 are provided between the side plates 4 of the case 3 of the suction unit 2 so that the suction unit 2 has three or more suction chambers. 6a, 6b, 6c ... And each suction port 7 is provided on the lower side of the suction chambers 6a, 6b, 6c ... And the average suction can be performed by selecting the size of the suction port 7. Since it is regulated as described above, dust is sucked into the suction unit 2 on average.

Further, since the total area of the respective suction ports 7 is set so as not to be so large as compared with the cross-sectional area of the suction hose 1, the suction force is stronger than the suction portion 2 of the conventional electric vacuum cleaner. Then the dust on the floor is sucked together with the airflow.

【Example】

 The attached drawings show an example of this embodiment, and show a suction part 2 of an electric vacuum cleaner in which a suction part 2 for sucking dust through a suction hose 1 is connected to a suction machine body a. A plurality of partition walls 5 are provided between the left and right side plates 4 of the case 3 of the suction unit 2 to form the suction unit 2 into three or more suction chambers 6a, 6b, 6c.

In the illustrated embodiment, a connecting portion 9 connected to the suction hose 1 is provided substantially in the rear upper part of the case body 3 of the suction portion 2, and a shaft core 10 of a connecting hole 10 between the connecting portion 9 and the case 3 is provided. Along the ', when looking at the connecting hole 10 from the front, the three partition walls 11a, 11b are arranged radially upward and downward at an interval of 120 ° from the center of the axis 10', respectively, and obliquely downward to the left and downward to the right. 11c is provided in the case 3, the upper end of the partition wall 11a is fixed to the upper plate of the case 3, and the front end portions of the partition walls 11a, 11b and 11c are fixed to the front plate of the case 3 and fixed to the connecting hole 10 respectively. Configure so that the suction areas are equal.

A groove-shaped suction port 7 is provided in the center of the bottom plate 12 of the case 3, and two partition walls 5b and 5c are erected from the bottom plate 12 between the side plates 4 and 4 of the case 3 inside the case 3. The front and rear ends thereof are fixed to the front plate and the rear plate of the case 3, and the other ends of the partition walls 5b and 5c are fixed to the other ends of the partition walls 11b and 11c so that the case 3 has three suction chambers 6a. , 6b, 6c, and the distance between the fixing positions on the bottom plate 12 of the distances 11b, 11c is selected so that the three suction ports 7a, 7b, 7c can suck on average.

The position where the partition walls 11b and 11c of the illustrated embodiment are fixed to the bottom plate 12 is determined by the length of the left and right suction ports 7a and 7c depending on the internal shape of the case 3 and the suction resistance of the suction unit 3. The figure shows a case in which the suction ports 7b are set to approximately half each and the air amounts sucked from the respective suction ports 7a, 7b, 7c are averaged.

Further, the total area of the suction ports 7 a, 7 b, 7 c is set so as not to be too large as compared with the cross-sectional area of the suction hose 1.

In the illustrated embodiment, the case where the total area of the suction ports 7a, 7b, 7c is formed to be substantially the same as the sectional area of the suction hose 1 is shown.

Reference numeral 13 in the drawing is a brush body provided around the bottom plate 12 of the suction portion 2.

Since the present embodiment is configured as described above, the suction port provided on the bottom plate 12 together with the air that is eaten by dust and dirt when the suction unit 2 is moved while operating the suction unit 2 while contacting the suction unit 2 with the floor surface. 7a, 7b, 7c are averaged and sucked, and the total area of the respective suction ports is set so as not to be too large as compared with the cross-sectional area of the suction hose 1. Therefore, the suction ports 7a, 7b, Dust, dust and the like are sucked into the suction chamber 6 together with air from 7c.

Although the suction chamber 6 is set to three compartments in the present embodiment, it is also possible to design the suction chamber 6 into three compartments or more by the same means.

[Effect of device]

 The present invention is an electric vacuum cleaner in which a suction unit for sucking dust through a suction hose is connected to a suction machine body as described above, and a plurality of partition walls are provided between side plates of a case of the suction unit to provide three suction units. The divided average suction method is adopted in which the above suction chamber is formed, and each suction port is provided on the lower side of this suction chamber so that average suction can be performed, so dust and dirt are averaged and sucked. Compared with the case where dust or dirt in the center is sucked in, like the suction part of an electric vacuum cleaner, there is no leftover dust and dirt, and even cleaning is possible. Becomes

Further, since the total area of the suction ports is set so as not to be too large as compared with the cross-sectional area of the suction hose, the suction force of the suction port is larger than that of the suction portion of the conventional vacuum cleaner. Is increased and dust and dirt can be sucked in more strongly.

As described above, the present invention is a practical and excellent electric vacuum cleaner that has a simple structure and is capable of efficiently and powerfully sucking and cleaning dust and dirt.
