Description

  The present invention relates to a cleaner head, and more particularly to a cleaner head having a sterilizing function.

  A vacuum cleaner generally used for cleaning is a vacuum cleaner head having a suction force generating part that generates a suction force and a dust collecting port that collects dust such as suctioning dust around the suction force. And a dust collection part that collects dust and the like sucked from the dust collection port, and the form of the entire vacuum cleaner is various. For example, the suction force generating part and the dust collecting part are formed in the vacuum cleaner body, and the vacuum cleaner head is connected via a hose, or the vacuum cleaner head has all the components incorporated. is there.

  And in recent years, the technique regarding the vacuum cleaner provided with the function which disinfects the collected garbage is disclosed. For example, Patent Document 1 below discloses a technique for disposing sterilization by disposing an ultraviolet lamp in an exhaust passage so that bacteria contained in garbage or the like or propagated are not exhausted. Moreover, the technique of disinfecting garbage etc. at the time of suction is disclosed in Patent Document 2 below. This patent document 2 discloses a configuration in which an ultraviolet lamp is provided on the front end side of the cleaner head and irradiates the cleaning surface itself. For example, the impact is generated by irradiating pests such as mites adhering to a carpet or the like. It is a technology that collects dust by weakening it.

  However, in the vacuum cleaner using the ultraviolet lamp disclosed in Patent Document 2, since the ultraviolet lamp is provided near the tip of the cleaner head and radiates outside, the ultraviolet rays emitted from the ultraviolet lamp leak to the outside. The possibility increases and the possibility of affecting the human body may arise. In addition, the structure that irradiates ultraviolet rays at the tip side of the vacuum cleaner head rather than the dust collection port, so much of the ultraviolet rays are irradiated to dust and pests before being sucked, and the object to be cleaned after cleaning The problem that the bactericidal effect with respect to a surface is low arises.

  For this reason, the present invention aims to provide a cleaner head that improves the disadvantages of the above-described conventional example, and in particular, can improve the sterilizing effect on the surface to be cleaned while suppressing ultraviolet leakage. To do.

  Therefore, a vacuum cleaner head according to one aspect of the present invention is a vacuum cleaner head having a dust collection port on the front side that is the forward running direction of the bottom surface facing the surface to be cleaned, and is configured to emit ultraviolet rays inside the vacuum cleaner head. An ultraviolet lamp that emits light is provided, and an exposure opening that exposes ultraviolet rays emitted from the ultraviolet lamp to the outside is provided behind the dust collection opening on the bottom side of the cleaner head.

  According to the above device, on the front side which is the forward running direction (the direction pushed by the operator) of the bottom surface of the cleaner head, dust and the like existing on the surface to be cleaned are collected at the dust collection port, and behind Ultraviolet rays are exposed to the surface to be cleaned from the exposure port located on the side. Therefore, since ultraviolet rays are irradiated to the surface to be cleaned after dust and the like are removed at the dust collection port, the sterilization effect by the ultraviolet rays on the surface to be cleaned can be improved. Since the dust collection port is formed on the rear side with respect to the position and is not formed extremely near the front end or near the rear end, the upper part of the exposure port is widely covered by the bottom surface of the cleaner head. Will be broken. Accordingly, it is possible to effectively suppress leakage of ultraviolet rays illuminated from the ultraviolet lamp to the outside, and it is possible to perform sterilization while suppressing the influence on the human body.

  And in the said structure, it is desirable to provide an exposure port in the vicinity of the center in the front-back direction of the cleaner head. It is further desirable that the exposure port is provided within a range narrower than the width of the dust collection port in a direction substantially perpendicular to the front-rear direction of the cleaner head.

  As a result, an exposure port is formed near the center of the bottom surface of the cleaner head in the front-rear direction and in the lateral direction perpendicular thereto, so that it is more effective for ultraviolet rays to leak from the periphery of the cleaner head. Can be suppressed. In addition, since the exposure port is formed in a range narrower than the width of the dust collection port, ultraviolet rays can be exposed only to the surface to be collected and the sterilization effect can be improved. it can.

  Furthermore, it is desirable that the exposure port be formed in a groove shape extending in a direction substantially perpendicular to the front-rear direction of the cleaner head. As a result, the ultraviolet light exposure range is wide in the direction perpendicular to the front-rear direction and narrow in the front-rear direction, so that the leakage of ultraviolet light from the front and rear ends of the cleaner head is effective when the cleaner head is running. It is possible to sterilize over a wide range while suppressing it.

  Since the present invention is configured and functions as described above, according to this, since the ultraviolet light is illuminated to the surface to be cleaned after dust and the like are removed at the dust collecting port, the ultraviolet light is applied to the surface to be cleaned. The sterilizing effect can be improved. Furthermore, since the upper part of the exposure port is widely covered with the bottom surface of the vacuum cleaner head, it is possible to effectively suppress leakage of ultraviolet light illuminated from the ultraviolet lamp to the outside, while suppressing the influence on the human body, It has an unprecedented excellent effect that sterilization can be performed.

  The present invention is characterized by the formation position of an exposure port that exposes ultraviolet rays having a sterilizing effect to the surface to be cleaned. Hereinafter, a specific configuration and operation will be described in Examples. In the embodiment, a vacuum cleaner in which a suction force generation unit, a dust collection unit, and the like are integrally provided in the vacuum cleaner head will be described as an example. However, the vacuum cleaner may have any configuration. For example, a vacuum cleaner having a configuration in which a main body portion provided with a suction force generating portion and a dust collecting portion and a vacuum cleaner head with a hose is provided on the main body portion may be used.

  A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a diagram illustrating the overall configuration of the cleaner, and FIG. 2 is a diagram illustrating the configuration of the back surface of the cleaner head. FIG. 3 is an explanatory view of the operation of the vacuum cleaner.

[Constitution]
As shown in FIG. 1, the vacuum cleaner in this embodiment includes a rod-shaped handle portion 2, an operation portion 3 held by an operator provided at one end thereof, and a cleaner connected to the other end of the handle portion 2. And a head 1. And this vacuum cleaner is equipped with the vacuum cleaner head 1 with most structures which make a vacuum cleaner function. The details will be described below. In addition, the structure of the bottom face of the cleaner head 1 facing the surface G to be cleaned is shown in FIG.

  Here, in the present invention, the direction in which the cleaner head 1 is pushed and moved by the operator is defined as the normal traveling direction (the direction of the arrow Y1 illustrated in FIGS. 1 to 3), and the normal traveling direction is defined as the front. Further, the direction opposite to the normal traveling direction is the rear. Therefore, the end surface of the cleaner head 1 opposite to the connection portion of the handle portion 2 is defined as a front end A, and the end surface of the handle portion 2 on the connection portion side is defined as a rear end B. Further, the front-rear direction is the vertical direction, and the left-right direction perpendicular to the front-rear direction is the horizontal direction.

  First, the vacuum cleaner head 1 is provided with a suction force generation unit 11 that generates a suction force in the vicinity of a connection portion with the handle 2. A dust collection box 12 that collects and accumulates dust and dust collected from the dust collection port 14 is formed at the upper center of the cleaner head 1 as will be described later. And the attraction | suction force by the said attraction | suction force generation | occurrence | production part 11 is urged | biased at least with respect to the dust collection box 12, and can collect the collected dust and dust with a suction force. In some cases, the suction force may be urged to the dust collection port 14 through the dust collection box 12.

  Next, the configuration of the bottom surface of the cleaner head 1 facing the cleaning target surface G will be described. As shown in FIG. 2, a total of four wheels 17 are provided on each of the front end A side and the rear end B side of the bottom surface of the cleaner head 1. As a result, the operator can easily drive the cleaner head 1, and the bottom surface of the cleaner head 1 is as high as the wheels 17 with respect to the surface G to be cleaned as shown in FIG. It will be located above.

  In the vicinity of the front end A of the bottom surface of the cleaner head 1, there is a rectangular dust collection port 14 having a long side perpendicular to the front-rear direction (the direction along the arrow Y <b> 1) of the cleaner head 1. Is formed. That is, a dust collection port 14 that is wide open in the lateral direction that is perpendicular to the front-rear direction of the cleaner head 1 is formed. Thereby, by making the cleaner head 1 run, a wider range can be scanned by the dust collection port 14, and the cleaning efficiency can be improved. The dust collection port 14 is provided with a rotationally driven brush 16 that rotates during the scanning of the cleaning target surface G, scrapes off dust and dirt present on the cleaning target surface G, and collects the dust. Operates to lead to mouth 14.

  Further, an exposure port 15 penetrating into the cleaner head 1 is located behind the dust collection port 14 of the cleaner head 1 (on the rear end B side) and slightly forward of the front and rear center. Is formed. The exposure port 15 is formed in a groove shape extending in a direction substantially perpendicular to the traveling direction of the cleaner head 1 and is divided into three parts. That is, the exposure port 15 is a groove-shaped through-hole having a longitudinal direction substantially parallel to the front end A and the long side of the dust collection port 14, and the three divided exposure ports 15 are formed in a series. ing. Further, all of the exposure ports 15 are provided inside the range of the dust collection port 14 in the longitudinal direction, that is, in a range narrower than the lateral width in the direction perpendicular to the traveling direction. As described above, the exposure port 15 is formed from the center in each of the front-rear direction of the cleaner head 1 and the lateral direction perpendicular to the front-rear direction. The groove width of the exposure port 15 along the front-rear direction of the cleaner head 1 is formed to be much narrower than the length (short side) in the front-rear direction of the dust collection port 14.

  An ultraviolet lamp 18 is provided inside the cleaner head 1 and above the exposure port 15. In addition, although arrangement | positioning of the ultraviolet lamp 18 is shown in FIG. 3, in this figure, the ultraviolet lamp 18 is block-ized and illustrated. Then, ultraviolet light having a sterilizing effect is emitted from the ultraviolet lamp 1 (see arrow L1 in FIG. 3), and this ultraviolet light is exposed to the outside from the exposure port 15, that is, the surface G to be cleaned ( (See symbol L2 in FIG. 3).

  As shown in FIG. 1, four lights 13 are provided on the end surface of the front end A of the cleaner head 1. This light 13 is for illuminating the destination of the cleaner head 1.

[Operation]
Next, the operation of the above-structured vacuum cleaner, in particular, the vacuum cleaner head 1 will be described with reference to FIG. First, the operator performs the cleaning while turning on the switch of the vacuum cleaner and mainly driving it in the direction of the arrow Y1 (forward running direction). At this time, the brush 16 is rotationally driven at the dust collection port 14 on the bottom surface of the cleaner head 1. Then, in the vicinity of the front end A of the cleaner head 1, dust and dust existing on the surface G to be cleaned are scraped toward the dust collection port 14 as indicated by an arrow Y 2, and the scraped dust and dust are collected. The dust box 12 is accommodated by the scraping force and suction force.

  Thereafter, the exposure port 15 formed behind the dust collection port 14 is positioned on the surface G to be cleaned as described above. Then, the ultraviolet ray L1 emitted from the internal ultraviolet lamp 18 is exposed from the exposure port 15 to the surface G to be cleaned as indicated by reference numeral L2. Therefore, it is possible to irradiate the cleaning target surface G after the dust and the like are removed at the dust collection port 14 with ultraviolet rays, and to sterilize the cleaning target surface G. At this time, since the upper part of the exposed ultraviolet ray L2 is widely covered with the bottom surface of the cleaner head 1, the leakage of the ultraviolet ray L2 to the outside can be effectively suppressed, and the human body such as an operator is affected. Can also be suppressed. Since the exposure port 15 is formed long in the direction perpendicular to the traveling direction of the cleaner head 1, that is, in the lateral direction, like the dust collection port 14, a wide range can be sterilized by one scan. .

  At this time, the length of the cleaner head 1 in the front-rear direction is formed short, but the groove width (width in the front-rear direction) of the exposure port 15 is also extremely narrow. Or the leakage of the ultraviolet-ray from the back end B can also be suppressed effectively.

  Here, although the case where the exposure port 15 is formed slightly forward from the center in the front-rear direction of the cleaner head 1 is illustrated above, it is not limited to this position. You may provide in the approximate center of the front-back direction of the cleaner head 1, and you may form in the back end B side rather than it. That is, it is not necessary to be near the outer periphery of the bottom surface of the cleaner head 1. Therefore, in the present invention, a position located inside the vicinity of the outer periphery of the cleaner head 1 is set as a desirable position where the exposure port 15 is formed, and such a position is set in the front-rear direction of the cleaner head 1 and perpendicular thereto. In the direction, it is expressed as near the center.

  The cleaner head according to the present invention can be used for a cleaner that collects dust and dirt on the surface to be cleaned, and has industrial applicability.
