Description

  The present invention relates to a vacuum cleaner.

  General vacuum cleaners guide the dust-containing air sucked from the suction port to the main body of the vacuum cleaner, remove the dust through the dust collecting part in the main body of the vacuum cleaner, and exhaust the air purified by the dust removal outside the main body of the vacuum cleaner. It is a configuration. The dust collecting unit is configured to capture and remove dust by filtration using a paper filter, or to capture and remove dust by centrifugal separation using a cyclone separation cylinder.

  A vacuum cleaner provided with a cyclone separation type dust collecting part is described in JP-A-2001-29288. The dust collecting part in this vacuum cleaner is configured to capture and remove dust by centrifugation using a single cyclone separating cylinder.

  In addition, as a cyclone separation type dust collecting unit in a vacuum cleaner, a dust separation device described in JP-T-10-511880 has a double structure of an outer separation tube and an inner separation tube. It is proposed that coarse dust is centrifuged to remove dust in the outer separation cylinder, and fine dust is centrifuged to remove dust in the inner separation cylinder.

In JP 2001-29288 A JP-T-10-511880

  It is important that the vacuum cleaner used in a general household is small and easy to handle, and it is necessary to reduce the size of the dust collecting unit and simplify the operation of discarding the captured dust.

  The dust collection part that captures dust with one cyclone separation cylinder captures both coarse dust and fine dust together. Therefore, when the trapped dust is discarded, the fine dust is easily scattered, and the dust disposal operation is troublesome. . Moreover, if it is going to improve the dust capture | acquisition (dust collection = dust removal) performance, a cyclone separation cylinder will become long and will enlarge.

FIG. 6 is a horizontal plan view with the upper lid and the upper case removed. FIG. 7 is a schematic diagram showing the flow of air in the cleaner body.

  As shown in FIG. 1, the electric vacuum cleaner in this embodiment includes a vacuum cleaner body 1, a hose 2, a hand operation tube 3, an expansion joint tube 4, and a suction port 5, and the vacuum cleaner body 1 and the hand operation tube 3 are connected to each other. A hose 2 is used for connection, and a suction port 5 is connected to the local operation pipe 3 via an expansion joint pipe 4 for use.

  The vacuum cleaner body 1 incorporates an electric blower (described later), and sucks in dust from the intake flow by suctioning from the suction port 5 by the suction force of the electric blower. Then, the vacuum cleaner main body 1 is sucked through the hand control tube 3 and the hose 2, and dust is collected (collected) by a cyclone separation type dust collection unit (described later), and then exhausted outside the machine.

  As shown in FIGS. 2 to 6, the vacuum cleaner main body 1 has a cyclone separating cylinder 104 and a dust collecting case 105 detachably mounted between the lower case 101 and the upper lid 102, and between the lower case 101 and the upper case 150. The second auxiliary filter 112, the electric blower 107, and the cord reel 110 are incorporated.

  As shown in FIG. 7, the vacuum cleaner main body 1 separates dust by centrifugal action by flowing dust-containing air from the inlet pipe 115 through the hose 2 into the cyclone separating cylinder 104 and turning it. The dust is conveyed to the dust collecting case 105 through the communication port 117, and the exhaust from the cyclone separation cylinder 104 passes through the inner cylinder 131 and is exhausted to the communication passage 120 provided at the lower part of the cyclone separation cylinder 104. Part of the air flows into the dust collection case 105 and is captured by the first auxiliary filter 106. The exhaust from the dust collection case 105 is sucked into the electric blower 107 through the second auxiliary filter 112 from the communication port 146 behind the first auxiliary filter 106. At this time, the exhaust from the cyclone separating cylinder 104 is also sucked into the electric blower 107. Exhaust air from the electric blower 107 passes through the filter 108, partly through an exhaust passage (not shown), partly flows through the cord reel 110, cools them, and then releases them outside the apparatus.

  The lower case 101 includes a traveling wheel 208 and a guide wheel (not shown) for causing the cleaner body 1 to travel on the floor surface, and the cyclone separating cylinder 104 and the dust collecting case 105 are detachably arranged side by side. In addition, the second auxiliary filter 112 is installed side by side.

  The upper lid 102 is attached to the upper rear portion of the upper case 150 so as to be able to rotate. When the upper lid 102 is closed, the inlet pipe 115 of the cyclone separation cylinder 104 and the hose connection port 116 abut against each other in an airtight state. And the upper opening 118 of the dust collecting case 105 are in contact with each other in an airtight state, and the communication passage 120 at the bottom of the cyclone separation cylinder 104 and the communication passage 145 provided at the lower portion of the dust collection case 105 are airtight. Abutting on the state, the communication port 146 and the filter case 113 in which the second auxiliary filter is accommodated are urged so as to abut on the airtight state. Although the axial direction of the cyclone separating cylinder 104 is oriented in the vertical direction, it may be inclined in the oblique direction instead of the vertical direction.

  When the upper lid 102 is opened upward, the cyclone separating cylinder 104 and the dust collecting case 105 are slightly lifted from the lower case 101. In this state, the dust collecting case 105 can be separated and taken out by holding the handle 123 at the top of the dust collecting case 105, and the dust collecting case 105 is opened by opening the first auxiliary filter 106 in the dust collecting case 105. Discard the dust inside.

  Furthermore, when the inside of the cyclone separation cylinder 104 is dirty, the upper handle 125 can be held and lifted from the lower case 101, and the cyclone separation cylinder 104 can be disassembled and cleaned.

  Further, the cyclone separating cylinder 104 and the dust collecting case 105 are molded using an antistatic resin agent, or dust is attached to the cyclone separating cylinder 104 and the dust collecting case 105 by applying an antistatic agent to the surface. The number of cleanings can be reduced.

  Next, with reference to FIG. 6, arrangement | positioning inside the vacuum cleaner main body 1 is demonstrated. FIG. 6 is a plan view of the state where the upper case 150 and the upper lid 102 are removed. The hose connection port 116 is located at the center in the width direction of the main body 1 when viewed from above, the center axis of the cyclone separation cylinder 104 is shifted from the center in the width direction, and air flows in substantially tangential direction of the cyclone separation cylinder 104. The inlet pipe 115 and the hose connection port 116 are arranged in a straight line. The dust collection case 105 is installed on the opposite side of the width direction from the center axis of the cyclone separation cylinder 104. Similarly, the electric blower 107 is installed on the opposite side of the center axis of the cyclone separating cylinder 104 in the width direction, and a second auxiliary filter 112 is provided on the front surface thereof. The cord reel 110 is installed beside the electric blower 107, and the central axis of the cyclone separating cylinder 104 is installed in the same direction in the width direction.

  By arranging in this way, the length of the main body can be shortened, and a small size and light weight can be achieved. Further, since it is not necessary to provide a bend or the like at the inlet portion of the cyclone separation cylinder 104, an effect of reducing loss can be obtained.

  Here, details of the cyclone separating cylinder 104 and the dust collecting case 105 will be described with reference to FIGS. 8 is an external perspective view of the cyclone separating cylinder 104, FIG. 9 is an external perspective view of the dust collecting case 105, FIG. 10 is a cross-sectional view taken along the line AA of FIG. FIG. 12 is a sectional view including the cyclone separating cylinder 104 and the communication port 117 of the dust collecting case 105, and FIG. 13 is a side view of the dust collecting case 105 viewed from the exhaust side. FIG. 14 is an external perspective view showing a combined state of the cyclone separating cylinder 104 and the dust collecting case 105. FIG. 15 is a longitudinal sectional view showing details of the first auxiliary filter 106 and the second auxiliary filter 112 and the filter in the communication passage on the cyclone exhaust side.

  The outer cylinder 135 of the cyclone separation cylinder 104 is provided with an inlet pipe 115 as an air intake port below the center of the cyclone separation cylinder 104 in the central axial direction, and the cyclone separation cylinder 104 having a substantially cylindrical shape. It is installed so that air can enter in the direction of approximately tangent. A communication port 117 is provided above the center of the cyclone separation cylinder 104 to allow air to flow into the dust collecting case 105 together with dust. An inner cylinder 131 is provided at the lower part of the cyclone separating cylinder 104 and is connected to the lower communication passage 120. The inner cylinder 131 is constituted by a partition wall 132 and a cylinder part 134, and a resin fiber net is formed in the cylinder part 134 as a net filter 133 by insert molding integrally with the cylinder part 134. As shown in FIG. 10, the net filter 133 may be only the upper plane of the cylindrical portion 134, or may be configured with a cylindrical portion on the side surface. Here, when the antistatic treatment is applied to the mesh filter 133, dust adhering to the mesh filter 133 is easily separated and cleaning is easy.

  The cyclone separating cylinder 104 is separated into an outer cylinder 135, an inner cylinder 131, and members forming the communication passage 120, and each is detachably fitted, and the respective members are in contact with each other while keeping airtightness. It should be noted that an elastic seal member may be interposed between the contact portions in order to realize an airtight contact. The cyclone separation cylinder 104 can be cleaned by separately separating the members that form the outer cylinder 135, the inner cylinder 131, and the communication passage 120, respectively.

  The dust collection case 105 is provided with an upper opening 118 at a position facing the communication port 117 of the cyclone separation cylinder 104, and both are in contact with each other while maintaining an airtight state. On the exhaust side of the dust collection case 105, a first auxiliary filter 106 attached to the filter frame 140 is provided. Both sides of the filter frame 140 are open, and are provided so as to rotate about a shaft portion provided at the bottom. When the filter frame 140 is closed, the main case 141 of the dust collecting case 105 and the filter frame 140 are provided. Are in contact with each other while maintaining an airtight state.

  When throwing away the trash, hold the handle 123 above the dust collection case 105, lift the dust collection case 105, pull the lever 142 that is integrated with the clamp part holding the filter frame 140 forward, and remove the filter frame 140. Open and do.

  The auxiliary filter 106 is preferably made of a foamable, washable material such as a plastic sponge or a washable non-woven fabric.

  Details of the first auxiliary filter 106 and details of the filter that abuts the outlet of the communication passage 145 will be described with reference to FIG.

  The first auxiliary filter 106 includes a filter A301, a filter storage frame 302, a filter B303, and a filter C304. The filter A 301 is formed integrally with the filter storage frame 302 and is injection-molded into the filter storage frame 302. The filter A302 has a low dust collection performance, and is used so that the dust that accumulates on the surface is easily removed when the garbage is discarded. Specifically, a mesh made of a plastic material such as polyester is used. If the fineness of the mesh is too coarse, it is preferable to use 100 to 200 mesh (100 mesh means one having 100 openings per inch) because the hair is likely to clog the mesh. . Note that when the antistatic treatment is applied to the mesh, the dust attached to the filter A is more easily separated.

  In addition, it may be composed of a hard non-woven fabric or the like, but if the dust collection performance is too high, clogging occurs quickly, so it is preferable to reduce the dust collection performance.

  It is preferable that the filter B303 has a higher dust collection performance than the filter A301 and can retain a large amount of dust in the filter. In this embodiment, a sponge made of a plastic material that is foamable and can be washed with water is used. In addition, you may comprise with the thick washable nonwoven fabric.

  Further, the filter C304 is injection-molded integrally with the filter frame 140. Here, a material having higher dust collection performance than the filters A301 and B303 is used. For example, a plastic nonwoven fabric that is a washable material is used. With this configuration, the dust that has passed through the filter A301 and the filter B303 can be captured by this filter, and the dust that has passed through the gap formed between the filter frame 302 and the filter frame 140 can also be captured. Can trap dust.

  The filter frame 140 is provided with a filter D305 so as to face a communication passage 145 formed on the cyclone exhaust side. Although this filter D does not occur normally, when dust such as hard metal flows from the cyclone side, the hard dust is damped and prevented from flowing out to the second auxiliary filter 112 side. . Although a mesh is specifically used here, a thin non-woven fabric that does not have a high dust trapping property and hardly clogs may be used. This filter is also made of a washable material.

  As described above, the first auxiliary filter 106 is composed of three layers to increase the dust collection characteristic as a filter and to increase the amount of dust that can be accommodated in the filter portion. Along with the effect of improving the dust collection performance of the cyclone due to the flow of the airflow to 103, the amount of dust that escapes to the second auxiliary filter 112 can be reduced, and the second auxiliary filter 112 can remove fine dust. Can be used at a higher height.

  As described above, since all the filters used in the cyclone separation cylinder, the dust collecting unit, and the like are configured to be washed, they can be cleaned by washing them together when throwing away the garbage. It is also possible to take out only the filter B303 and clean it by washing it with water.

  A communication passage 145 and a communication port 146 are integrally provided at the lower part of the dust collection case 105. Accordingly, the dust collecting case 105 is divided into the main case 141, the communication passage 145, and the communication port 146 in the lower part of the filter frame 140, but the part where both are joined comes into contact with each other while maintaining airtightness. Yes. Further, the communication path 120 of the cyclone separating cylinder 104 is also in contact with the airtight state.

  The filter frame 140 is also in contact with a filter case 113 that houses the second auxiliary filter 112 provided in front of the electric blower 107 while maintaining airtightness. In order to realize the airtight contact described above, an elastic seal member may be interposed between the contact portions.

  In the vacuum cleaner main body 1 configured as described above, when the electric blower 107 is operated, dust-containing air flows into the cyclone separation cylinder 104 from the inlet pipe 115 of the cyclone separation cylinder 104 due to the intake air force. By turning, the dust is centrifuged, lifted upward in the cylinder, and conveyed to the dust collecting case 105 side. The dust-removed air flows out from the inner cylinder 131 of the cyclone separation cylinder 104 to the communication passage 120 through the net filter 133. The mesh filter 133 functions to prevent fiber dust from blowing through.

  Air from the communication passage 120 flows to the second auxiliary filter 112 via the communication passage 145 and the communication port 146.

  Air containing dust from the communication port 117 of the cyclone separation cylinder 104 flows into the dust collecting case 105 through an upper opening 118 provided at the upper part of the dust collecting case 105, and dust in the air is collected by the first auxiliary filter 106. It is stopped and deposited before the first auxiliary filter 106. The air that has passed through the auxiliary filter flows toward the second auxiliary filter.

  The dust removal performance of the first auxiliary filter 106 is determined by the ability of the filter material, but it is preferable to have the ability to separate up to μm order dust. However, if the dust removal capability is too high, clogging is likely to be accelerated, so it is desirable to determine the balance with the overall dust removal capability.

  Note that the second auxiliary filter 112 preferably has the ability to capture even sub-μm order dust, and has a higher dust collection performance than the first auxiliary filter 106 having three layers. Specifically, the second auxiliary filter 112 uses a fold-folded electrostatic filter that captures dust by static electricity, and the filter's dust collection characteristics deteriorate when washed with water. Yes. Accordingly, the second auxiliary filter 112 is integrally provided with an outer frame, and dust accumulated on the filter surface can be removed by hitting or rubbing the outer frame in a garbage bag placed on the floor or the like. . At this time, if the frame of the second auxiliary filter 112 is hard, the dust removal capability is high. Note that the second auxiliary filter 112 preferably has antibacterial or deodorizing properties. Further, when the antistatic treatment is applied to the second auxiliary filter 112, dust attached to the second auxiliary filter 112 is easily separated and cleaning can be easily performed.

  Most of the dust that has entered the vacuum cleaner body 1 is stored in the dust collection case 105. Therefore, the dust collection case 105 may be taken out of the vacuum cleaner body 1 and removed. It is desirable to dispose of the trash before dust overflows from the dust collection case 105. For this reason, the dust collection case 105 is provided with a waste disposal line 155 at a position facing the upper opening 118 as shown in FIG. 9, so that the user can discard the waste with reference to this. The garbage disposal line does not face horizontally or vertically, but when the dust accumulates in the dust collection case 105, the part close to the upper opening 118 is filled with the garbage at the end. It is set.

  In this embodiment, since the air flow in the cleaner body 1 is divided into two paths as shown in FIG. 7, a pressure difference is applied to the dust in the dust collecting case 105 in the air flow direction. This pressure difference causes the dust to be constantly compressed. Since this pressure difference increases as the amount of accumulated dust increases, it also has a feature that the amount of compression increases as the amount of dust increases. Therefore, more dust can be stored in the dust collection case 105, and therefore the cycle of waste disposal can be lengthened.

  Furthermore, since the flow rate on the exhaust side of the cyclone separator 104 is smaller than when the air does not pass through the dust collecting case 105, the resistance of the cyclone separator 104 can be reduced. Therefore, it has the feature that the suction power of the vacuum cleaner can be further increased.

  Further, when the amount of dust accumulated in the dust collection case 105 increases, the resistance when passing through the dust collection case 105 increases, so the flow rate flowing in the dust collection case decreases. Therefore, when there is a large amount of dust that is likely to generate odor, the amount of air passing through that portion is reduced, and there is also an effect that it is difficult to remove the odor outside the vacuum cleaner.

  Further, when the inside of the communication passage 145 and the communication port 146 becomes dirty, it can be easily cleaned with the dust collecting case 105 taken out.

  In addition, since the inlet pipe 115 and the inner cylinder 131 of the cyclone separator 104 are provided below, a communication port can be provided in the upper part and dust spillage that has entered the dust collecting case 105 can be prevented.

  Further, since the dust collecting case 105 is arranged on the side surface of the cyclone separating cylinder 104, the length direction of the cyclone separating cylinder 104 can be increased without increasing the height of the vacuum cleaner main body 1. It has the feature that the separation ability of can be increased.

Furthermore, since it is difficult to receive fluid force such as a ring and heavy dust tends to stay in the cyclone separation cylinder 104, the cyclone separation cylinder 104 can be easily taken out from the inlet pipe 115 by taking out the handle 125 and tilting it. It also has the feature of being able to.

  As shown in FIG. 14, the cyclone separating cylinder 104 and the dust collecting case 105 may be provided integrally. In this case, the mass held by hand when the trash is thrown away becomes large, and the handling property is lowered. Since the communication passage 120 and the communication passage 145 are integrally configured between the dust collection case 105 and the dust collection case 105, perfect airtightness is maintained, so that an increase in loss due to leakage or the like can be suppressed, and suction work can be suppressed. The rate can be made higher.

  In addition, the communication passage 120, the communication passage 145, and the communication port 146 may be formed of separate members that come into contact with the lower case 101. However, when the inside of the communication passage is dirty, there is an aspect that it cannot be easily cleaned. However, it is possible to reduce the number of places that keep the whole airtight. Moreover, since the direction which maintains airtightness can be made into an up-down direction, the characteristic which is easy to maintain airtightness can be given.

  In addition, the communication passage 120, the communication passage 145, and the communication port 146 may be formed of separate members that come into contact with the lower case 101.
