Problems solved by technology

[0004] However, the temperature of the exhaust gas returned from the electric blower to the inhaler rises when passing through the electric blower, and the temperature of the returned air gradually rises when it passes through the electric blower, and the temperature of the returned air gradually rises. Problems that adversely affect the durability of components, especially hoses

Embodiment

[0021] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] 1 indicates the main body of the vacuum cleaner, such as figure 1 As shown, it is composed of an upper case 2, a lower case 3, a dust collection cover 4, and a partition wall 7 described later mounted on the lower case 3, and a hose connected to the main body side described later is formed on the front side of the vacuum cleaner body 1. The hose connection port 5 of the connection part 17 is formed with an exhaust port not shown in the figure on the rear wheel 6 . In the above-mentioned lower case 3, there is a partition wall 7 formed by a material with a higher thermal conductivity at intervals between the inside of the lower case 3. The partition wall 7 constitutes a part of the outer wall of the vacuum cleaner body 1. In the lower case 3 and the partition wall 7, an exhaust flow path B1 communicating with the hose connection port 5 is formed. ...

Abstract

An electric vacuum cleaner is provided to suppress the temperature rise of circulating air in such way that the exhaust from an electric fan built in the cleaner body is circulated into a suction means through a hose or a pipe. This vacuum cleaner is provided with a partition wall 7 to be mounted on the lower case 3 which is constituted of the cleaner main body 1, and the partition wall 7 formed of a material with comparatively high heat conductivity is mounted at a distance from the backside of the lower case 3. The space between the partition wall 7 and the lower case 3 is made to form a circulating route which a part of exhaust of the electric fan 14 is circulated into.

Description

technical field [0001] The present invention relates to an electric vacuum cleaner, in particular to an exhaust return (circulation) type electric vacuum cleaner which returns the exhaust gas from the electric blower installed in the vacuum cleaner body to the inhaler through a hose and a conduit. Background technique [0002] In general floor mobile electric vacuum cleaners, the exhaust from the electric blower installed in the main body of the vacuum cleaner is discharged to the outside from the exhaust port formed on the back side of the main body, etc., since the exhaust from the electric blower is exhausted from the exhaust If it is exhausted through the outlet, it will be blown out with a considerable wind force, so the dust deposited on the floor or carpet will be blown away by the action of the exhaust wind, and the disadvantageous situation will be diffused in the room. [0003] Therefore, in order to reduce the exhaust air discharged from the exhaust port and impro...
