Japanese Patent Laid-Open No. 4-36775

  However, in the configuration of the conventional vacuum cleaner described in Patent Document 1, the filter has a sufficient ventilation performance, but the filter is pushed out to the exhaust downstream side by the exhaust pressure due to the exhaust discharged from the electric blower. As a result, the cover body made of resin is warmed by the heat of the exhaust, so that there is a problem that the claws that detachably fix the cover body come off.

  On the contrary, if the holding force of the nail is increased to prevent the nail from coming off, it becomes difficult to attach and detach the cover body. Although not described in the above-mentioned Patent Document 1, there is a configuration in which the claw is configured as a separate part and biased by a spring body in order to prevent the cover body from being detached while ensuring the detachability of the cover body. There was a problem of increasing the cost and cost.

  The present invention solves the above-described conventional problems, and prevents the cover body from coming off while ensuring the usability of attaching and detaching with a nail configured integrally with the cover body, and is inexpensive, easy to use and has improved quality.

  In order to solve the above-mentioned conventional problems, a vacuum cleaner according to the present invention includes a dust collecting chamber and an electric blower body that includes an electric blower and forms an exhaust section that discharges exhaust from the electric blower. And a filter that covers the exhaust part, collects dust contained in the exhaust, and has an outer peripheral side surface formed of a hard material, a filter chamber that houses the filter, and an exhaust port that covers the filter chamber. A cover body, provided on the outer peripheral side surface of the cover body with a claw to be engaged with the vacuum cleaner body, and provided on the cover body with a filter pressing portion that contacts the outer peripheral side surface of the filter; Is in contact with the filter so as to incline in the direction away from the side closer to the claw and toward the downstream side of the exhaust with respect to the cross section of the claw. When the coater is moved to the downstream side of exhaust gas, because the contact surface with the filter is inclined, the force is generated to open outward in the filter holding part. As a result, the outer periphery of the cover body opens outward, and the claws provided on the outer peripheral side surface move in a direction strongly related to the cleaner body, thereby preventing the cover body from coming off.

Further, the vacuum cleaner of the present invention covers a dust collecting chamber, a vacuum cleaner main body having an electric blower with a built-in electric blower and forming an exhaust portion for discharging exhaust gas from the electric blower, and the exhaust portion. A filter that collects dust contained in the exhaust gas and has an outer peripheral surface formed of a hard material; a filter chamber that houses the filter; and a cover body that covers the filter chamber and includes an exhaust port. A claw that is locked to the vacuum cleaner body is provided inside the outer body of the body, and a filter holding part that is in contact with only the approximate center on the downstream side of the filter is provided on the cover body. Then, only the center part of the cover body is pushed up, and the outer peripheral surface is pulled inward and falls inward. It is those that can be prevented.

  The vacuum cleaner of the present invention can prevent detachment of the cover body while ensuring the usability of attaching and detaching with a nail configured integrally with the cover body for fixing the filter. A vacuum cleaner can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a cross-sectional view of the electric vacuum cleaner according to Embodiment 1 of the present invention, and FIG. 2 is an enlarged cross-sectional view of main parts of the electric vacuum cleaner (a-a cross section in FIG. 1).

  In FIG. 1, reference numeral 1 denotes a main body of the vacuum cleaner. Behind the main body of the vacuum cleaner 1, an electric blower chamber 3 having an electric blower 2 that generates suction air for sucking dust is disposed. Is provided with a dust collection chamber 5 in which a dust collection unit 4 for collecting dust is arranged, and the electric blower chamber 3 has an exhaust unit for discharging the exhaust discharged from the electric blower 2 to the outside. 3a is provided, and a filter chamber 7 is provided in communication with the exhaust part 3a so as to cover the exhaust part 3a and to arrange a filter 6 for removing a minute amount of dust contained in the exhaust of the electric blower 2. . 8 is a cover body which has the exhaust port 9, covers the filter chamber 7, and fixes the filter 6 to the cleaner body 1.

  Next, in FIG. 2, the filter 6 includes a filter material 6 a that ensures air permeability in the center portion, and a frame body 6 b that holds the outer periphery of the filter material 6 a and is formed of a hard material. The outside of the outer peripheral side surface constituting the cover body 8 has a claw 10, and the claw 10 is engaged with a hook portion 11 formed on the cleaner body 1, so that the cover body 8 can be detachably attached to the cleaner body 1. It can be fixed to.

  The filter 6 is sandwiched and fixed by the attachment surface 12 of the cleaner body 1 and the filter pressing portion 13 provided on the cover body 8. The filter pressing portion 13 is configured at a position where it is connected to the inside of the claw 10, and cutout portions 14 are provided on both sides of the claw 10.

  Regarding the contact between the filter pressing portion 13 and the filter 6, the filter pressing portion 13 is in contact with the frame body 6 b of the filter 6. Further, the contact surface 15 between the filter pressing portion 13 and the frame body 6b is formed so as to be inclined so as to be inclined in the direction away from the side closer to the claw 10 and in the downstream direction of the exhaust gas.

  About the vacuum cleaner in this Embodiment comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. As shown in FIG. 2, the exhaust discharged from the electric blower 2 passes through the filter 6, removes a very small amount of dust contained in the exhaust, and is discharged outside the cleaner body 1 through the exhaust port 9. The filter material 6a for filtering the exhaust gas needs to improve the dust removal rate of the filter material 6a in order to remove a small amount of dust contained in the exhaust gas. It is necessary to make sex worse.

  Therefore, a slight pressure loss occurs in the filter material 6a. Due to the pressure loss, while the electric blower 2 is operated and the exhaust gas is discharged, a force is generated on the filter 6 in the downstream direction of the exhaust gas, and the cover body 8 holding the filter 6 is similarly downstream of the exhaust gas. The operation pushed out to the side occurs.

  The filter 6 is sandwiched and fixed between the attachment surface 12 of the cleaner body 1 and the filter pressing portion 13 of the cover body 8. Regarding the contact between the filter pressing portion 13 and the filter 6, the filter pressing portion 13 is in contact with the substantially central portion of the frame body 6 b of the filter 6.

  About the vacuum cleaner in this Embodiment comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. As shown in FIG. 3, the claw 10 is formed inside the outer shell of the cover body 8, and the contact surface of the filter pressing portion 13 with the filter 6 is only the central portion of the filter 6, so that the filter 6 is moved backward by exhaust. When the cover body 8 is moved, only the central portion thereof is pushed up, and the outer peripheral surface of the cover body 8 is pulled inwardly, so that the claw 10 is strongly hooked on the hook portion 11 provided in the cleaner body 1. The cover body 8 can be prevented from coming off.

  Further, if the outer shell of the cover body 8 is configured as a part of the outer shell of the cleaner body 1, the cover body 8 can be prevented from coming off without increasing the number of parts, and the detachability of the cover body 8 can be secured. On the other hand, an inexpensive electric vacuum cleaner can be provided by configuring it as a part of the outline of the cleaner body 1.
