Description

The present invention relates to a vacuum cleaner, and more particularly to a vacuum cleaner that improves the cooling efficiency of a cord reel.

(B) Conventional technology In recent years, electric blowers have been increased in power in order to improve dust collection efficiency. However, the drawback that the temperature of the cord reel increases greatly due to an increase in the input of the electric blower. there were. Therefore, a part of a partition that divides an electric blower room for storing an electric blower and a code reel room for storing a code reel is cut out, and a part of the exhaust air of the electric blower flows into the code reel room, thereby reducing the code reel. Cooling was considered (JP-A-62-299228).

However, since the exhaust of the electric blower is hot,
The code reel could not be cooled sufficiently.

(C) Problems to be Solved by the Invention The present invention has been made in view of the above-mentioned disadvantages, and has as its object to provide a vacuum cleaner capable of efficiently cooling a cord reel.

(D) Means for Solving the Problems The present invention relates to a cleaner main body having a dust collecting chamber formed at a front portion, an electric blower room formed at a rear portion of the cleaner main body and housing an electric blower, and the cleaner A code reel chamber is provided in the rear part of the main body in parallel with the electric blower room and stores a code reel, an exhaust chamber formed on the downstream side of the electric blower room of the cleaner main body, and the electric blower room and the exhaust chamber are partitioned. A filter, an exhaust port formed in the cleaner main body, for discharging exhaust air from an exhaust chamber to the outside of the cleaner main body, and communicating the exhaust chamber with the code reel chamber; And an opening that leads to the opening.

(E) Function The exhaust air of the electric blower is purified by the filter, flows into the exhaust chamber, and is exhausted from the exhaust port to the outside of the cleaner body. Part of the exhaust gas that has flowed into the exhaust chamber flows into the code reel chamber. Exhaust efficiently.

(F) Embodiment One embodiment of the present invention will be described below in detail with reference to FIGS.

Reference numeral 1 denotes a cleaner main body. A dust collecting chamber 3 is provided at a front part of the vacuum cleaner so as to be opened and closed by a dust collecting lid 2. The code reel chamber 7 is provided side by side.

Reference numeral 8 denotes an exhaust port formed at the rear of the cleaner main body 1.
An exhaust chamber 9 is formed between the electric blower chamber 5 and the exhaust port 8, and the electric blower chamber 5 and the exhaust chamber 9 are partitioned by a filter 10 generally called a HEPA filter. 9 has a cross-sectional area that is sharply larger than the communication hole in which the filter 10 is mounted.

Reference numeral 11 denotes an opening formed in a partition wall 12 for partitioning the cord reel chamber 7 and the exhaust chamber 9, and a part of the exhaust of the electric blower 4 flowing into the exhaust chamber 9 from the electric blower chamber 5 through the filter 10. It leads to the code reel chamber 7.

Reference numeral 13 denotes a cord outlet formed in the code reel chamber 7, which pulls out the cord 14 wound around the code reel 6 and exhausts the exhaust air of the electric blower 4 flowing into the code reel chamber 7. I have.

When the electric blower 4 is driven, dust is sucked into the dust collection chamber 3 together with air via a suction tool and a suction hose (not shown), and is separated into dust and air in the dust collection chamber 3 so that only dust is removed. It is stored. On the other hand, air is exhausted from the motor chamber 5 through the exhaust port 8 through the filter 10 and the exhaust chamber 9. The exhaust gas is cleaned by the filter 10 by collecting fine dust contained in the exhaust gas, and the flow velocity decreases due to the resistance of the filter 10 and the sudden increase in the cross-sectional area in the exhaust chamber 9, so that the exhaust noise is greatly reduced. Is done.

Part of the exhaust gas is led from the exhaust chamber 9 to the cord reel chamber 7 through the opening 11 and exhausted from the cord outlet 13. The exhaust gas that has flowed into the code reel chamber 7 is cooled in the air passage from the filter 10 and the electric blower chamber 5 to the code reel chamber 7 and has a relatively low temperature.
Is cooled efficiently. Further, since the exhaust gas flowing into the code reel chamber 7 is purified by the filter 10, dust and the like do not adhere to the contacts of the code reel 6, and no defective contacts or the like occur.

In this embodiment, a HEPA filter is used as the filter 10, but another filter such as urethane may be used as the filter. Also, the code reel room 7
The exhaust flowing into the outlet is exhausted from the outlet 13. However, an exhaust port is formed on the side of the cord reel chamber 7, and the outlet 13 is formed.
May be exhausted from the exhaust port.

(G) Effects of the Invention As described above, according to the present invention, the exhaust is sufficiently cooled by passing through the air passage from the electric blower room to the cord reel room and passing through the filter, and the code reel is cooled by low-temperature exhaust. Therefore, the code reel can be efficiently cooled. Further, since the exhaust gas for cooling the code reel is purified by the filter, there is an effect that dust does not adhere to the contact of the code reel, and no defective contact or the like occurs.
