Abstract

PROBLEM TO BE SOLVED: To gently discharge exhaust air for preventing dust from being blown up and scattering into an environment to be cleaned, by employing a circulating air current system for suction and exhaust air. SOLUTION: In order to prevent jet air current near the jetting port of a cleaning port, a nozzle is arranged integrally just under the jetting port to jet air toward a necessary position in a cleaning chamber to generate a suction air current. The influence of the attracting force, which is generated at the edge of the cleaning port, is reduced or removed by using a roller or a wind shielding wall rich in sliding property. With respect to jetting of a circulating air current caused by the separation of the cleaning port from a surface to be cleaned, an air stream detector for detecting the change of air pressure in the cleaning chamber depending on the presence/absence of circulating air in the chamber is arranged to cut off power to a motor on the basis of detection signal by utilizing a control circuit to stop a motor fan to stop a jet stream.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circulating air flow type electric vacuum cleaner.

[0002]

2. Description of the Related Art In a conventional circulating air flow type electric vacuum cleaner, there is no exhaust from a main body or 10% of circulating air current.
In order to eliminate the influence of the attraction force, the head ejects about 25% of the circulating airflow at the head portion.

[0003]

In the case of the main body, the main body itself takes in about 5% of the intake air due to switching for the replacement of the circulating air flow, or about 5% of the exhaust air that has passed through each filter. This is systematically released gently on the suction and discharge head side to prevent dust from scattering, and in the cleaning chamber of the suction and discharge head, the circulating airflow should not be ejected from the cleaning port. However, when the state of the surface to be cleaned or the cleaning port is separated from the surface to be cleaned, and when the circulating airflow blows out from the cleaning port, the blowing airflow is stopped. Even if there is, be able to continue operation when you know it.

[0004]

Means for Solving the Problems The main body itself is provided with a freely openable air inlet, and the air circulating from the air suction / discharge head is mixed and sucked, and the branch of the exhaust air flowing through each filter and the deodorizing device is separated. A branch exhaust, which can be opened and closed, is provided with a branch exhaust exhaust port, and an exhaust port for guiding the circulating airflow of the remaining exhaust after the branch exhaust of the exhaust flow is attached, and the branch exhaust exhaust port and the exhaust port are vertically moved. The guide unit is connected to the suction / discharge head unit. A cleaning room is arranged in the suction / discharge head portion, and the cleaning room forms an irregularly shaped rectangular parallelepiped including a surface to be cleaned. The windshield structure is provided between the ceiling plate and the respective rollers facing the surface to be cleaned which the rollers are in contact with, and the side surfaces of the ceiling plate and the respective rollers and the surfaces to be cleaned are provided. Each wind shield wall is provided with a wind shield structure, the wind shield wall is provided with a through hole through which each of the roller shafts passes, and the roller is attached to each of the bearings attached to the inner surface of the outer side surface of the cleaning room. , And each of the rollers is made rotatable, thereby forming an irregularly shaped rectangular parallelepiped. In the upper part of the ceiling board, a channel-like, central, partitioning guideway that blocks both sides is formed on the left and right,
An exhaust port for flowing a circulating air flow, which is exhaust from the main body, is provided near the inside of each wind shield wall of the ceiling plate, for example, on the right side, and immediately below the exhaust port, in a required direction of the cleaning room. A nozzle capable of injecting the circulating airflow is provided, and an intake port through which the circulating airflow is supplied is provided near the inside of the left wind shield wall to supply air from the main body. In addition, in the center of the cleaning chamber, a communication pipe of an airflow detection device that detects a changing air pressure depending on the presence or absence of the circulating airflow is attached, the cleaning port is separated from the cleaning surface, and the circulating airflow is reduced. When the circulating airflow does not flow into the cleaning chamber, the airflow detection device is activated and emits an appropriate electric signal, and the electric signal is supplied to the motor fan of the motor fan according to the electric signal. However, depending on the condition of the surface to be cleaned, if the operator wants to continue the operation even if there is some ejected airflow, the airflow detection device should be turned off. The operation of the airflow detection device is stopped by switching the hand switch. Further, a branch exhaust speed reduction unit, which is a part of the device, which constitutes the suction / discharge head unit, has a circulating airflow of 5%.
% Is gently discharged in the opposite direction to the surface to be cleaned by the upper case of the suction / discharge head, so that the human body is not felt and dust is not blown up. In addition, since the main body itself can open and close the intake port and the branch exhaust port through which the main body suctions, the operator can select any one according to the environment of the cleaning place.

It is the same as the upper surface and has a box shape of a required length, and each roller is arranged in parallel with the inside of each of the front plate and the back plate in the lower case, and the rollers are formed of an elastic body in a required shape. , The length is the same as the lower case, arranged at required intervals, the front plate and the back plate are arranged as guard plates and do not contact, the surface of each roller is Side case, and The lower case is set about 3 mm from the lower end face of the lower case, and the lower end face of the side case and the lower case does not come into contact with the surface to be cleaned. Each is to prevent ventilation between the ceiling plate, the ceiling plate,
A sponge of a required layer having a high elasticity is provided on the ceiling plate side, and a required thickness of a slippery Teflon (registered trademark) material is provided on the roller side. Of the same length as the roller, the ceiling plate,
Airtightness can be maintained between the roller and the roller,
In addition, the roller is rich in lubricity and can be rotated lightly because of gentle contact with the Teflon plate. The side facing surface is provided with a hanging partition plate that matches the end side surface of the roller and allows the roller portion to escape from the ceiling plate, and a shielding wall that covers the surface made of the required elastic body with a highly slippery film To form an irregular rectangular parallelepiped including the surface to be cleaned, which makes contact with the partition plate on the end side surface and the surface to be cleaned as well as the surface of each roller to prevent ventilation. The bearing attached to the shaft end of the roller shaft is supported by a bearing supporting portion attached to a predetermined position inside the side surface of each side case, and a supporting plate for reinforcing is provided at a required position on the lower case back plate. And support at the tip of the support plate. A vehicle is arranged, and by supporting in cooperation with each of the rollers, a stable support of the suction / discharge head portion is intended.In the center of the guide path, a connecting portion which is horizontally connected to the guide means in a horizontal manner is provided. The connecting portion consisting of a concentric cylinder having a triple structure has a central connecting pipe communicating with the guideway having an intake port, and a second connecting pipe communicating with the guideway having an exhaust port. Furthermore, the third connecting pipe communicates with a branch exhaust chamber of the branch exhaust deceleration section, which will be described later, and the above-described exhaust port is attached to the ceiling plate near the partition plate, and directly below the exhaust port. A nozzle is provided for injecting exhaust gas in a required direction in the cleaning chamber.
It is attached to the ceiling plate, near the partition at the target position with the exhaust port, and usually, between the nozzle and the intake port, the circulation is performed by exhaust and intake from the main body. The air flow is caused to flow, and the air pressure in the cleaning chamber is reduced by flowing the circulating air flow, and a suction force is generated between the cleaning port of the cleaning chamber and the surface to be cleaned due to a difference from the atmospheric pressure. In order not to be affected by the suction force, the respective rollers are provided, and the short side shield wall is also a member having high lubricity, the resistance force due to suction is low, and the operation and conveyance of the suction / discharge head portion are easily performed. In the center of the front of the upper case, an airflow detection device connected to the communication pipe is arranged. In the airflow detection device, one of the chambers is located inside the required cylinder after the diaphragm is sealed. Indicates the air pressure in the cleaning room, and the other room The central movable part of the diaphragm is connected to the lever of the micro switch, and when the air pressure in the cleaning chamber and the atmospheric pressure are the same, the return torque of the micro switch is reduced. Therefore, the diaphragm returns to the equilibrium position, which detects that there is no flow of the circulating airflow in the cleaning chamber, and the air pressure in the cleaning chamber becomes lower due to the flow of the circulating airflow. The diaphragm is pressurized to the cleaning chamber side with a pressure difference from the atmospheric pressure, the central movable part moves, the micro switch is operated, and it is detected that a circulating air flow is present in the cleaning chamber, The cleaning port is separated from the cleaning surface, the jet flow from the nozzle flows out from the cleaning port, and the circulating air flow flows into the cleaning chamber. With the detection signal from the airflow detection device, the motor of the motor fan connected to the electric control circuit is cut off, the motor fan is stopped, and the airflow from the cleaning port can be stopped. However, even if there is some jet airflow depending on the state of the surface to be cleaned, if it is unavoidable to perform the operation, the airflow detection device can be switched off by the hand switch, and the operation can be performed. The branch exhaust reduction section, which is one of the devices constituting the suction / discharge head section, is located on the ceiling plate in the side case and the connection section arranged in the center, which are attached to both sides behind the upper case. The branch exhaust deceleration section is formed in the left and right pockets, and the branch exhaust chamber located below is connected to the third connection pipe of the connection section as described above. The ceiling of The sponge of the required layer of open-cell foam is arranged on the jetty to improve the temper, and the exhaust flow of the branch exhaust is made uniform to reduce the exhaust speed from the exhaust port. A circulating air flow having a hole, an upper case detachably arranged, a branch exhaust exhaust port attached to the main body, opening and closing the branch exhaust exhaust port, and discharging and stopping exhaust from the branch exhaust deceleration section.
