Description

  The present invention relates to a filter and an air conditioner including the filter, and more particularly to a structure of an endless filter that can be rolled up.

  A conventional filter 100 as shown in FIGS. 7A to 7C is known as a filter used in an air conditioner. This filter 100 captures dust contained in the air sucked from the suction port as indicated by an arrow a, and forms a net body 101 woven with fibers having a thin uniform diameter in an endless shape, A driving unit 102 for winding the filter 100 and a dust removing unit 105 for removing dust trapped by the net body 101 at the same time that the filter 100 is rolled up are covered with a cover 106 and attached to the air conditioner.

  The endless filter 100 is arranged in the air passage of the air conditioner so as to capture the dust in the air sucked from the suction port and clean the air blown out to the air-conditioned room. At the same time, the dust collected by the filter 100 is removed from the filter 100 by the dust removing means 105 having the brush 103 and the dust collecting case 104. It is comprised so that it may be stored in case 104 (for example, refer patent document 1).

  However, since the filter 100 described above is always rubbed by the dust removing brush 103, the mesh body 101 is formed by weaving fibers having a thin uniform diameter, so that the brush 103 has insufficient strength against friction. Although not shown in the figure, when the strength of the filter 100 is increased by supporting the mesh body with a frame portion or a crosspiece, the opening area by the mesh body is increased. It has the problem of decreasing and increasing air resistance.

  As shown in FIGS. 2 to 6, the filter 7 includes a net body 8 in which first mesh yarns of at least the warp yarn 9 and the weft yarn 10 are woven together, and the front side of the net body 8 is driven to wind up the filter 7. It can be rolled up in the lateral direction toward the drive motor 13 and the drive drum 15, and is provided with dust removing means 19 that can remove dust trapped at the same time as being rolled up, and is formed in an endless shape and covered with a cover 21. It is configured to be

  In the filter 7 shown in FIG. 1, the drive motor 13 and the drive drum 15 that are driven to wind up the filter 7 are omitted, and the fibers constituting the mesh body 8 shown in FIGS. 2 to 5 are endless. The fibers along the longitudinal direction in which the filter 7 formed in a shape is wound are referred to as warp yarns 9, and the fibers in the short direction perpendicular to the direction in which the filter 7 is wound are referred to as weft yarns 10. In the present embodiment, the front side of the filter 7 is described as being wound up in the horizontal direction, but the front side of the filter 7 may be wound up in the vertical direction.

  Here, the configuration in which the filter 7 is composed of a net body 8 in which the first net yarns of at least the warp yarn 9 and the weft yarn 10 are woven together and is formed in an endless shape so as to be able to wind up in the horizontal direction is shown in FIGS. This will be described in detail with reference to FIG.

  As shown in FIGS. 2 and 4, the endless filter 7 is provided on one side of the filter 7, and is driven via a linkage gear 14 linked to a drive motor 13 and an auxiliary drive. The drum 16 is installed between the driven drum 17 and the auxiliary driven drum 18 provided on the other side without slack, and between the driving drum 15 and the auxiliary driving drum 16 and the driven drum 17 and the auxiliary driven drum 18. The front surface portion of the filter 7 that is laid on is disposed so as to face the suction port 2a and the suction port 2b shown in FIG.

  The drive motor 13 drives a drive gear 13a interlocked with the drive motor 13 and a brush drum 19b having a brush 19a constituting the dust removing means 19, and via a linkage gear 14 linked to the drive gear 13a. The driving drum 15 is driven and the auxiliary driving drum 16 arranged so as to press the filter 7 to be rolled up is driven so that the filter 7 is wound up by the driving drum 15 and the auxiliary driving drum 16 to be installed. The driven drum 17 and the auxiliary driven drum 18 are configured to be driven through the filter 7.

  At that time, a large number of needle-like convex pieces (not shown) hooked on the mesh body 8 are provided on the outer peripheral portion of the drive drum 15, so that the needle-like protrusions rotate simultaneously with the rotation of the drive drum 15. The filter 7 can be smoothly wound up while the convex piece (not shown) hooks the net body 8.

  When the drive drum 15 linked to the drive gear 13 a is driven by the drive motor 13, the filter 7 is wound up toward the drive drum 15 and at the same time, the brush drum 19 b is driven by the drive motor 13 and is captured by the filter 7. The dust is removed by a brush 19 a that is in contact with the filter 7 wound around the drive drum 15.

  The dust removed from the filter 7 is stored in a case 20 provided at the lower part of the dust removing means 19 and is periodically discarded by the user outside the apparatus.

  The filter 7 is composed of a mesh body 8 in which at least the first mesh yarns of the warp yarn 9 and the weft yarn 10 are woven together, and eliminates the frame portion and the crosspiece portion to suppress the airflow resistance, so that it can be wound up in an endless shape. In addition to being able to capture dust, it is configured to have strength that prevents deformation and damage by rubbing with the brush 19a during winding.

  Next, based on FIG. 2, FIG. 3, and FIG. 6 shown as Example 1, the mesh body 8 is configured not to be supported by the frame portion or the crosspiece portion, thereby suppressing the ventilation resistance, A description will be given of the configuration of the filter 7 having strength to prevent damage.

  The mesh body 8 is woven with first mesh yarns of warp yarns 9 parallel to each other and first mesh yarns of weft yarns 10 parallel to each other, and a vertical second mesh yarn 11 made of fibers thicker than the warp yarns 9 is A part of the warp yarn 9 is formed at a predetermined pitch, and the first net yarn and the vertical second net yarn 11 are woven so as to be equally spaced.

  As a result, since the vertical second mesh thread 11 that is not widely formed like a so-called frame part or crosspiece part is woven, the increase in ventilation resistance is suppressed, and the strength that prevents deformation or damage during winding is provided. In particular, the tensile strength applied in the longitudinal direction of the filter 7 when the filter 7 is rolled up is increased by increasing the strength in the longitudinal direction, which is the winding direction of the filter 7 made of the mesh body 8 having strength. The strength against the force applied when dust is removed by the brush 19a can be increased without causing deformation or damage by the force.

  The vertical second mesh thread 11 may not be woven at a predetermined pitch at a plurality of locations but may be woven in one piece, and further enhances the strength of the mesh body 8. In addition, instead of the first mesh yarn by the warp yarn 9, the vertical second mesh yarn 11 may be woven at a predetermined pitch.

  Next, based on FIG. 4, FIG. 5, and FIG. 6 shown as the second embodiment, the mesh body 8 is configured not to be supported by the frame portion or the crosspiece portion, thereby suppressing the ventilation resistance, A description will be given of the configuration of the filter 7 having strength to prevent damage.

  The mesh body 8 is woven with a first mesh yarn made of warp yarns 9 parallel to each other and a first mesh yarn made of weft yarns 10 parallel to each other, and a horizontal second mesh yarn 12 made of fibers thicker than the weft yarn 10, A part of the weft 10 is formed at a predetermined pitch, and the first and second second yarns 12 are woven so as to be equidistant.

  As a result, the horizontal second mesh yarn 12 that is not widely formed like a so-called frame portion or crosspiece portion is woven, so that the strength is such that deformation and damage do not occur during winding while suppressing an increase in ventilation resistance. In particular, the strength in the short direction perpendicular to the winding direction of the filter 7 made of the strong mesh 8 is increased, and when the filter 7 is rolled up, the short direction of the filter 7 is increased. In addition, it is possible to increase the resistance against the displacement of the mesh by the convex piece of the brush drum 19b when the filter 7 is wound up.

  In addition, the horizontal second net yarn 12 may not be woven at a plurality of locations at a predetermined pitch, but may be a single woven configuration, and in order to further enhance the strength of the net body 8. In addition, instead of the first mesh yarn by the weft yarn 10, the horizontal second mesh yarn 12 may be woven at a predetermined pitch. Alternatively, although not shown, the net body 8 may have a configuration in which a vertical second net yarn 11 and a horizontal second net yarn 12 are woven into a part thereof.

  As described above, according to the configuration of the present invention, the warp yarns 9 constituting the mesh body 8 are woven with a first mesh yarn having the same diameter as the weft yarn 10 and a larger diameter than the weft yarn 10 at a predetermined pitch. Or the weft yarn 10 constituting the mesh body 8 has a larger diameter than the warp yarn 9 and the first mesh yarn having the same diameter as the warp yarn 9. The endless filter 7 and the filter 7 that can be rolled up with the strength of the mesh body 8 and the increase in air resistance suppressed by being composed of the vertical second mesh yarns 12 woven at a predetermined pitch. The air conditioner 1 provided can be provided.
