Description

Technical Field

[0001] The present invention relates to a cleaning machine head integrated with lighting and a cleaning machine equipped with the same. More specifically, since it can irradiate light not only at a short distance but also at a long distance as required, it is possible to more reliably confirm the presence or absence of foreign substances on the cleaning target surface even in a somewhat dark environment, and thus the present invention relates to a cleaning machine head integrated with lighting that can clean more cleanly than before and a cleaning machine equipped with the same.

Background Art

[0002] FIG. 1 is a perspective view of a general cleaning machine. Referring to this figure, a normal cleaning machine 1, that is, a vacuum cleaner 1, is a device that generates a vacuum using a motor and then uses this to suck foreign substances such as dust, and includes a cleaning machine body 10, a cleaning machine head 20, and a connection unit 30. The cleaning machine body 10 is provided with vacuum generating means such as a motor.

[0003] Thus, by grasping the handle portion 31 of the connection unit 30, placing the cleaning machine head 20 on the cleaning target surface, and turning on the device, cleaning can be performed. For reference, the cleaning machine 1 in FIG. 1 shows a wired cleaning machine, but a wireless cleaning machine in a similar form also has the same structure.

[0004] On the other hand, in addition to the cleaning machine 1 in the form shown in FIG. 1, it is also widely known that lighting is added to the cleaning machine head 20 to irradiate light on the cleaning target surface. When lighting is added to the cleaning machine head 20 in this way, it is suitable for confirming the presence or absence of foreign substances on the cleaning target surface even in a somewhat dark environment. However, in the case of existing cleaning machines, since light is irradiated only on the floor at a short distance adjacent to the cleaning machine head 20, the substantial effect and performance of the lighting are inevitably reduced, and thus the need for technological development to complement this is raised.

[0013] The rotary foreign object suction unit may further include a protective casing coupled to one side of the rotating brush, which protects a portion of the belt and the driven pulley.

[0014] The system may further include an input unit for inputting signals for the operation of the near-range light irradiator and the far-range light irradiator; and a controller for controlling the operation of the near-range light irradiator and the far-range light irradiator based on the input signals from the input unit. [Effects of the Invention]

[0015] According to the present invention, since light can be irradiated not only at close range but also at long range as needed, it is possible to more reliably confirm the presence or absence of foreign matter on the surface to be cleaned even in somewhat dark conditions, thereby resulting in a cleaner cleaning than before.

[0024] Referring to these drawings, the present invention can irradiate light not only at close range but also at long range as needed, so that the presence or absence of foreign matter on the surface to be cleaned can be confirmed more reliably even in dim light, thereby enabling cleaner cleaning than before.

[0025] The present invention, which can provide such effects, may apply to the lighting-integrated vacuum cleaner head 100 shown in Figures 2 to 6, and to vacuum cleaners (not shown) equipped with the lighting-integrated vacuum cleaner head 100. That is, after connecting a vacuum cleaner hose or pipe to the connector of the lighting-integrated vacuum cleaner head 100, it can be used as a single product, a vacuum cleaner, and such a vacuum cleaner also falls within the scope of the present invention. In this case, the vacuum cleaner can be wired or wireless, and its form can also be diverse. Therefore, specific external appearances have been omitted.

[0026] The lighting-integrated vacuum cleaner head 100 according to this embodiment may include a head cover unit 110, a rotary foreign object suction unit 150, a short-range light irradiation unit 115, and a long-range light irradiation unit 160.

[0027] The head cover unit 110, as an external structure of the lighting-integrated vacuum cleaner head 100 according to this embodiment, includes a base cover 120, a top cover 130, and a pair of side covers 140. Since the head cover unit 110 can be formed by assembling the base cover 120, top cover 130, and the pair of side covers 140, maintenance convenience is enhanced. That is, since only these parts can be replaced, it can contribute to cost reduction.

[0028] The base cover 120 forms the lower part of the head cover unit 110. A foreign matter suction port 121 for sucking up any foreign matter that may remain on the surface to be cleaned is provided on one side of the base cover 120.

[0029] Multiple wheels 122, 123 that can rotate on the surface to be cleaned are attached to the base cover 120. The multiple wheels 122, 123 include a main wheel 122 and a sub-wheel 123 that is relatively smaller than the main wheel 122. Both the main wheel 122 and the sub-wheel 123 are arranged in pairs.

[0030] The top cover 130 forms the upper part of the head cover unit 110. In other words, the top cover 130 is a structure positioned on top of the base cover 120 and forms the location where the long-distance light irradiation unit 160 is positioned. Specifically, the lighting installation section 131 of the top cover 130 is used to mount the support structure, including the long-distance light lamp 161.

[0031] The pair of side covers 140 form both sides of the head cover unit 110. The pair of side covers 140 are means of being assembled together with the base cover 120 and the top cover 130 in the side regions of the base cover 120 and the top cover 130. Therefore, when disassembling the head cover unit 110, the side covers 140 should be disassembled first.

[0032] The rotary foreign object suction unit 150 is coupled to the foreign object suction port 121 area of ​​the head cover unit 110 and is a means for guiding foreign objects to be sucked in based on rotational motion.

[0033] Such a rotary foreign matter suction unit 150 includes a rotary brush 151 rotatably coupled to the foreign matter suction port 121 area of ​​the head cover unit 110, a motor 152 that generates a driving force to rotate the rotary brush 151, a drive pulley 153 connected to the motor shaft of the motor 152, a driven pulley 154 axially coupled to the rotary brush 151, and a belt 155 connecting the drive pulley 153 and the driven pulley 154. As a result, when the motor 152 is driven by a predetermined operating signal, the driving force of the motor 152 is transmitted to the drive pulley 153, the belt 155, and the driven pulley 154, which guides the rotary brush 151 to rotate, thereby allowing foreign matter on the surface to be cleaned to be sucked into the foreign matter suction port 121, as shown in Figure 2.

[0034] A protective casing 156 is coupled to one side of the rotating brush 151. The protective casing 156, while coupled to one side of the rotating brush 151, can be used as a means to protect a portion of the belt 155 and the driven pulley 154.

[0035] On the other hand, as mentioned above, in dark places it can be difficult to confirm whether or not foreign matter is present on the surface to be cleaned, making cleaning work difficult. To solve this problem, a short-range light irradiator 115 and a long-range light irradiator 160 are mounted on the lighting-integrated vacuum cleaner head 100.

[0036] The short-range light irradiation unit 115 is provided in the lower region of the front end of the head cover unit 110 in the direction in which the head cover unit 110 moves forward for cleaning, and is a means for irradiating light into the short-range area of ​​the surface to be cleaned adjacent to the head cover unit 110. In other words, as shown in Figures 3a and 3b, the short-range light irradiation unit 115 irradiates light into the short-range area of ​​the surface to be cleaned adjacent to the head cover unit 110 to check whether or not foreign matter is present at that location.

[0037] In contrast, the long-range light irradiation unit 160 is provided on the head cover unit 110 in the upper region of the short-range light irradiation unit 115, and is a means for irradiating light to the long-range region of the surface to be cleaned, either together with the short-range light irradiation unit 115 or independently of the short-range light irradiation unit 115. In other words, as shown in Figures 3a and 3c, the long-range light irradiation unit 160 irradiates light to the long-range region of the surface to be cleaned, which is away from the head cover unit 110, to check whether or not foreign matter is present at that location.

[0038] For reference, Figure 3b is a diagram of the operating state when only the short-range light irradiation unit 115 is operating, Figure 3c is a diagram of the operating state when only the long-range light irradiation unit 160 is operating, and Figure 3a is a diagram of the operating state when both the short-range light irradiation unit 115 and the long-range light irradiation unit 160 are operating. In practice, when the lighting-integrated vacuum cleaner head 100 according to this embodiment is in operation, it is preferable that both the short-range light irradiation unit 115 and the long-range light irradiation unit 160 are operating as in Figure 3a, but the cases in Figures 3b and 3c are also possible, and all of these matters should be considered to fall within the scope of the present invention.

[0039] The short-range light irradiation section 115 includes multiple LEDs and is located in the lower region of the front end of the head cover unit 110 in the direction in which the head cover unit 110 moves forward. The multiple LEDs can be integrally coupled to the lower region of the front end of the head cover unit 110 while still bonded to the PCB. In particular, the short-range light irradiation section 115 is coupled to the front end of the base cover 120 of the head cover unit 110.

[0040] In contrast, the long-distance light irradiation unit 160 is provided on one side of the front end of the head cover unit 110 in the direction in which the head cover unit 110 moves forward for cleaning, and is a means for irradiating the surface to be cleaned with long-distance light when foreign matter is sucked up by the action of the rotary foreign matter suction unit 150.

[0041] Such a long-distance light illumination unit 160 may include a lighting installation unit 131, a long-distance light lamp 161, a lamp supporter 170, and a long-distance light lens 165.

[0042] The lighting installation section 131 is a portion of the top cover 130 that protrudes upward from the upper front half. In other words, the lighting installation section 131 is integrally formed during the manufacturing of the top cover 130. A lighting installation space 132 is formed inside the lighting installation section 131. A long-range light lamp 161, a lamp supporter 170, etc., are arranged in the lighting installation space 132. The lighting installation space 132 forms an independent spatial structure that does not communicate with the foreign matter intake port 121.

[0043] The long-range light lamp 161 is a means of emitting light, i.e., long-range light. Multiple long-range light lamps 161 are provided and assembled on the lamp PCB 162. The long-range light lamps 161 may also be LEDs.

[0044] The lamp supporter 170 is a means for supporting the lamp PCB 162 on which the long-distance light lamp 161 is mounted, and is coupled to the lighting installation space 132 of the lighting installation section 131.

[0045] Such a lamp supporter 170 may include a supporter body 171, a PCB slot 172 provided in the supporter body 171 into which the lamp PCB 162 is inserted and coupled, and a pair of lens supports 173 symmetrically connected on both sides of the supporter body 171 to support the far-field optical lens 165.

[0046] Since the lamp PCB 162, which is equipped with the long-range light lamp 161, is fitted into the PCB slot 172 of the supporter body 171, installation and maintenance of the lamp PCB 162 are made easier.

[0047] The outer walls of the pair of lens supports 173 are provided with assembly bosses 174, each having a through-hole 174a. By fastening screws into the through-holes 174a of the assembly bosses 174 or engaging them with projections, the lamp supporter 170 can be easily attached and detached.

[0048] Furthermore, a positioning step portion 173a is formed in the end region of the lens support 173, into which the long-range optical lens 165 is positioned and detachably fitted.

[0049] The long-range light lens 165 is detachably connected to the entrance of the lighting installation section 131 and is a means of transmitting light from the long-range light lamp 161 to the long-range area of ​​the surface to be cleaned. The periphery of the long-range light lens 165 forms a flange 165a so that the long-range light lens 165 is positioned on the positional step portion 173a of the side plate 173.

[0050] In this embodiment, the long-range light lens 165 is applied as a convex long-range light lens 165 with a forward-convex cross-section so that the light from the long-range light lamp 161 can be diffused and directed towards the distance. The long-range light lens 165 may be made of transparent plastic.

[0051] On the other hand, the lighting-integrated vacuum cleaner head 100 according to this embodiment further includes an input unit 180 and a controller 190 as means for controlling the device.

[0052] The input unit 180 is a means for inputting signals for the operation of the short-range light irradiation unit 115 and the long-range light irradiation unit 160. The input unit 180 may be provided in the form of a button or in the form of a remote control. In the former case, it may be provided on one side of the head cover unit 110, or on the handle (not shown) when used with a vacuum cleaner.

[0053] The controller 190 controls the operation of the near-range light illuminator 115 and the far-range light illuminator 160 based on the input signal from the input unit 180. That is, the controller 190 can control the operation of only the near-range light illuminator 115 as shown in Figure 3b, only the far-range light illuminator 160 as shown in Figure 3c, or both the near-range light illuminator 115 and the far-range light illuminator 160 as shown in Figure 3a. As mentioned above, when the lighting-integrated vacuum cleaner head 100 according to this embodiment is in operation, it is preferable that both the near-range light illuminator 115 and the far-range light illuminator 160 are in operation as shown in Figure 3a, but the cases in Figures 3b and 3c are also possible.

[0054] A controller 190 that performs such a role may include a central processing unit 191 (CPU), memory 192 (MEMORY), and support circuit 193 (SUPPORT CIRCUIT).

[0055] In this embodiment, the central processing unit 191 may be one of various industrially applicable computer processors to control the on / off operation of the far-distance light lamp 161 based on the input signal of the input unit 180.

[0056] Memory 192 is connected to the central processing unit 191. Memory 192 may be installed locally or remotely as a computer-readable recording medium, and may be at least one or more readily available memories such as random access memory (RAM), ROM, floppy disk, hard disk, or any digital recording form.

[0057] The support circuit 193 is coupled with the central processing unit 191 to support the typical operation of the processor. Such a support circuit 193 may include a cache, power supply circuit, clock circuit, input / output circuit, subsystem, and the like.

[0058] In this embodiment, the controller 190 controls the operation of the near-field light irradiation unit 115 and the far-field light irradiation unit 160 based on the input signals of the input unit 180, and such a series of control processes may be stored in memory 192. Typically, software routines may be stored in memory 192. Software routines may also be stored or executed by other central processing units (not shown).

[0059] Although the process according to the present invention has been described as being executed by software routines, at least a portion of the process of the present invention can also be executed by hardware. Thus, the process of the present invention may be implemented by software executed on a computer system, by hardware such as an integrated circuit, or by a combination of software and hardware.

[0060] As described above, in the lighting-integrated vacuum cleaner head 100 of this embodiment, the long-range light lamp 161 of the long-range light irradiation unit 160 is particularly used, so when the long-range light lamp 161 is turned on, it is easy to check for the presence or absence of foreign matter on the surface to be cleaned, even in dim light. Therefore, cleaning becomes easier.

[0061] According to this embodiment, which operates based on the structure described above, light can be irradiated not only at close range but also at long range as needed. Therefore, even in somewhat dark conditions, the presence or absence of foreign matter on the surface to be cleaned can be confirmed more reliably, and as a result, cleaning can be performed more thoroughly than in conventional methods.

[0062] Figure 14 is a control block diagram relating to a lighting-integrated vacuum cleaner head according to a second embodiment of the present invention.

[0063] Referring to the figure, in this embodiment, both the near-range light irradiation unit 115 and the far-range light irradiation unit 160 are turned on / off in conjunction with the operation of the motor 152. When the input unit 280, for example as an on / off switch, is activated, the motor 152 operates under the control of the controller 290, and the rotary foreign object suction unit 150 operates to suck up foreign objects. At this time, the near-range light irradiation unit 115 and the far-range light irradiation unit 160 may be automatically turned on in conjunction with the operation of the motor 152. In this case, there is no need to provide separate switches or remote controls for the operation of the near-range light irradiation unit 115 and the far-range light irradiation unit 160. Of course, when cleaning is completed and the operation of the motor 152 stops, the operation of the near-range light irradiation unit 115 and the far-range light irradiation unit 160 may also be automatically turned off.

[0064] Even when this embodiment is applied, light can be irradiated not only at close range but also at long range as needed, so the presence or absence of foreign matter on the surface to be cleaned can be confirmed more reliably even in dim light, thereby enabling cleaner cleaning than before.

[0065] Figure 15 is a plan view of a vacuum cleaner head with integrated lighting according to a third embodiment of the present invention, Figure 16 is an enlarged view of the main part of the far-distance optical lens region, and Figure 17 is a control block diagram relating to the vacuum cleaner head with integrated lighting of Figure 15.

[0066] Referring to these drawings, the lighting-integrated vacuum cleaner head 300 according to this embodiment is substantially identical to that of the first embodiment. However, in the case of the lighting-integrated vacuum cleaner head 300 according to this embodiment, an illuminance sensing unit 395 is further mounted on the head cover unit 310.

[0067] The illuminance sensing unit 395 senses the illuminance and is connected to the controller 390. Based on the value detected by the illuminance sensing unit 395, the controller 390 controls the operation of the near-range light irradiator 115 and the far-range light irradiator 160 so that they are automatically turned on / off. In other words, in this embodiment, there is the advantage that the operation of the near-range light irradiator 115 and the far-range light irradiator 160 can be manually controlled on / off by the input unit 180, or the operation of the near-range light irradiator 115 and the far-range light irradiator 160 can be automatically controlled on / off by the illuminance sensing unit 395.

[0068] Furthermore, in this embodiment, a film slot 365a is formed in the long-range light lens 365, which is an element of the long-range light irradiation unit 360, and an optical film 366 is provided in a replaceable manner through the film slot 365a. The optical film 366 is a functional film that changes the hue of light, polarizes it, or diffuses it, and by installing such an optical film 366 as needed, the effect of detecting foreign objects is further improved.

[0069] Even when this embodiment is applied, light can be irradiated not only at close range but also at long range as needed, so the presence or absence of foreign matter on the surface to be cleaned can be confirmed more reliably even in dim light, thereby enabling cleaner cleaning than before.

[0070] Thus, it will be obvious to those skilled in the art that the present invention is not limited to the embodiments described and can be modified and transformed in various ways without departing from the spirit and scope of the invention. Accordingly, such modifications or variations should be considered within the scope of the claims of the present invention.

[0071] (Modes for carrying out the invention) Modes for carrying out the invention have been described together with the best mode of the invention described above. [Industrial applicability]

[0072] The present invention relates to a vacuum cleaner that can irradiate light not only at close range but also at long range as needed, thus enabling more reliable confirmation of the presence or absence of foreign matter on the surface to be cleaned, even in somewhat dark conditions, and allowing for thorough cleaning. This has potential for industrial applications.
