Technical field

[0001] The invention relates to a cleaner. Background of the technology

[0002] Generally, a vacuum cleaner is a device that sucks up dust and dirt from surfaces to be cleaned using a suction motor in the main body and then filters the dust and dirt in the main body.

[0003] Cleaners can be divided into manual cleaners, which a user moves themselves to clean, and automatic cleaners, which move automatically to clean.

[0004] Depending on the type, manual cleaners can be divided into floor cleaners, hand cleaners, table cleaners and stick cleaners.

[0005] Furthermore, a hand-held vacuum cleaner is disclosed in the related technology in Korean patent specification no. 10-1127088 (filed on March 8, 2012).

[0006] The handheld vacuum cleaner features a suction tube, an airflow generator, a cyclone, a power supply, and a handle.

[0007] The cyclone is positioned between the handle and the suction pipe, the airflow generator is located directly above the handle, and the power supply is located directly below the handle. Thus, the airflow generator and the power supply are located behind the cyclone.

[0008] The power supply consists of several battery cells arranged in parallel. A problem with the known technology is that the cleaner must be disassembled to disconnect the power supply.

[0009] Since the battery cells are laid in parallel on a layer, it is also problematic that the volume occupied by the power supply is large and the maximum voltage that the power supply can deliver to a suction motor is small. Disclosure of the invention Technical problem

[0010] The revelation provides a cleaner that a user can use more conveniently by distributing the total weight.

[0011] The revelation provides a cleaner in which the maximum charging voltage of a battery can be increased and which can be designed compactly.

[0012] The revelation provides a cleaner whose cooling performance is improved for a battery.

[0013] The revelation provides a cleaner in which battery cells can be arranged separately in multiple rows. Technical solution

[0014] A cleaner of the invention comprises a battery housing and a battery which is detachably coupled to the battery housing.

[0015] Furthermore, the cleaner may have a suction motor that generates suction power and a handle with a control unit for entering commands to turn the suction motor on or off.

[0016] The battery compartment can be located on one side of the handle. For example, the battery compartment can be located below the handle, and the battery can be detached from the compartment downwards.

[0017] The battery may include: a frame, several battery cells held within the frame, a battery holder surrounding the multiple battery cells, and a partition to divide the multiple battery cells into multiple rows.

[0018] The direction in which the battery is installed in the battery housing can be parallel to the orientation of the multiple battery cells in a state where the multiple battery cells are supported by a battery holder.

[0019] Furthermore, the battery may include: a battery management unit to manage the voltage of the multiple battery cells; and a barrier located between the multiple battery cells and the battery management unit.

[0020] The battery holder may comprise: a first holder located on the upper section of the partition and surrounding the upper sections of the multiple battery cells; and a second holder located on the lower section of the partition and surrounding the lower sections of the multiple battery cells.

[0021] The holders can each have: several first cell sleeves that surround the entire circumference of some of the multiple battery cells; and several second cell sleeves that surround only sections of the circumference of another of the multiple battery cells, so that the battery cells are arranged in multiple rows in a zigzag pattern.

[0022] In this embodiment, two adjacent second cell sleeves are spaced apart with respect to the partition between them, and the distance between the centers of two adjacent second cell sleeves is shorter than the distance between the centers of two adjacent first cell sleeves.

[0023] To reduce the size of the battery holder, the holders may each further have a third cell sleeve, which is arranged in an area corresponding to the area between several second cell sleeves and surrounds sections of the circumference of another of the several battery cells.

[0024] The frame may have contact ribs that can come into contact with battery cells exposed from the second cell sleeve and the third cell sleeve to prevent battery cells supported by the battery holder from moving within the frame.

[0025] The contact ribs can be rounded with a curvature corresponding to the curvature of the battery cells in order to increase the contact area between the battery cells and the contact rib.

[0026] The battery management unit may have a circuit board, the lock may have a plate spaced away from the circuit board, and a direction of travel of each of the multiple battery cells may cross the circuit board and the plate.

[0027] The lock may have a guide projection extending from the plate to guide the position to be attached to the circuit board, and a mounting lug to which a through-circuit fastening is attached to improve work efficiency when the circuit board and the lock are combined.

[0028] The circuit board can have a projection through-hole that passes through the guide projection and a mounting hole that passes through the mounting.

[0029] Furthermore, the cleaner may include: an upper conductor connecting two battery cells across the multiple battery cells; and an upper conductive plate connected to the upper conductor and to the battery management unit.

[0030] The plate can have a first guide section that guides the upper conductive plate to the circuit board, and the circuit board can have a second guide section that the upper conductive plate passes through, so that the upper conductive plate can be connected to the battery management unit.

[0031] Furthermore, the cleaner may include: a lower conductor connecting two battery cells among the multiple battery cells; a lower conductive plate connected to the lower conductor; and a wire connecting the lower conductive plate and the battery management unit.

[0032] The board can have a first wire guide section that guides the wire, and the circuit board can have a second wire guide section that guides the wire so that the wire can be connected to the battery management unit.

[0033] The frame may have a movement-preventing rib projecting from the inside to prevent movement of the lock and the battery management unit, and the circuit board may have a rib slot through which the movement-preventing rib passes. The lock may have a rib receiving groove in which the rib passing through the rib slot is received.

[0034] The frame may have a movement-preventing rib that protrudes from the inside to prevent movement of the lock and battery management unit; the lock may have a reinforcing rib that extends upwards from the edge of the plate; and the movement-preventing rib may sit on the reinforcing rib. Beneficial effects

[0035] Since, according to the proposed invention, the battery can be separated from the battery housing, it is possible to charge the battery separately on a charging station.

[0036] Furthermore, since the battery cells are arranged in a zigzag pattern, even with an increased number of battery cells the degree of increase in the size of the battery is low, so that the battery can be designed compactly and the maximum charging volume can be increased.

[0037] Furthermore, since the holders surrounding the battery cells are arranged in such a way that they surround sections of the battery cells, the size of the battery holders can be reduced, allowing the battery to be designed compactly.

[0038] Furthermore, even if the battery cells in any row catch fire, it is possible to prevent the battery cells in other rows from catching fire by means of the partition.

[0122] The first main body clamps 630are on the undersides of the hinge coupling sections 620 arranged, but can be spaced away from the floor if the cleaner 1 is placed on the floor. That is, clamping slots. 623 , which are concave upwards, are on the undersides of the hinge coupling sections 620 formed, and the first main body clamps 630 can be in the terminal slots 623 be arranged. This prevents damage to the first main body clamps. 630 impede.

[0123] Furthermore, the first main body clamps 630 in the terminal slots 623 Arranged in such a way that no water can come into contact with the first main body clamps 630 come when the cleaner 1 is placed on a floor.

[0134] Furthermore, a coupling slot can 614 to couple the second hook 476 of the second coupling section 474 above the second excavation hole 612 of the inner casing 610 be formed. The coupling slot 614 It could be a hole or a groove.

[0135] The second catch 476 of the second coupling section 474 can be inserted into the locking slot 614 when inserting it into the inner housing 610 be deployed.

[0136] Fig. Figure 11 is an exploded perspective view of the battery according to an embodiment of the invention, Fig. Figure 12 is a perspective view of a battery holder of the invention, and Fig. 13 is a top view of the battery holder according to Fig. 12.

[0137] With reference to Fig. 10 to Fig. 13 can the battery 40 furthermore, several battery cells 430 , one of the battery cells430 supporting battery holder 440 , one of the voltages of the battery cells 430 managing battery management unit 480 and with the battery management unit 480 connected battery terminals 490 exhibit.

[0138] The battery cells 430 , the battery holder 440 and the battery management unit 480 can through the frame 410 be covered.

[0139] Furthermore, the battery 40 a ban 450 exhibiting features between the battery cells 430 and the battery management unit 480 is arranged.

[0140] The lockdown 450 blocks heat transfer from the battery cells 430 to the battery management unit 480 .

[0141] The frame 410 can provide an initial framework 420 and a second frame 460exhibiting, which is connected to the lower section of the first frame 420 is coupled.

[0142] A lead 422 is on the top of the first frame 420 formed, and clamping holes 424 , the second main body clamps to be described later 670 (see Fig. 23) can proceed at a lead 422 be educated.

[0143] The clamping holes 424 are through the top of the projection 422 formed through it. So, while the battery is being placed into the battery casing 60 When inserted upwards, the second main body clamps can be used. 670 (see Fig. 23) with the battery terminals 490 via the terminal holes 424 be connected.

[0144] The lead 422 can be on one side from the center of the first frame 420It should be positioned so that a user can easily recognize the direction in which the battery is located. 40 into the battery compartment 60 is used. For example, the advantage can 422 closer to the second coupling section 474 between the first coupling section 470 and the second coupling section 474 be positioned.

[0145] One seat 461 , in which the lower end of the first frame 410 It sits, can be found at the top of the second frame 460 be educated.

[0146] The battery management unit 480 can be used with the top of the lock 450 be coupled. The battery management unit 480 can have one or more mounting holes 482 exhibit in order to participate in the blockade 450 to be fastened by fixings.

[0147] Through the battery holder 440 can the battery cells 430They can be arranged in upright positions. For example, the longitudinal direction of the battery cells can be 430 be parallel to the directions in which the battery 40 into the battery compartment 60 is used and separated from it.

[0148] Through the battery holder 440 can the battery cells 430 be arranged in several rows.

[0149] Although not limited to this, the battery cells can 430 for example, seven battery cells, and through the battery holder 440 Some of the seven battery cells may be arranged in two rows. However, it should be noted that the number of battery cells 430 is not subject to any restrictions.

[0150] The battery holder 440 can a partition wall 441 to divide the battery cells 430 in two separate rows, first holders 422, which are located at the upper section of the partition 441 are formed, and second holders 445 have, which are located at the lower section of the partition 441 are educated.

[0151] The first holders 442 surround the upper sections of the battery cells 430 , and the second holders 445 surround the lower sections of the battery cells 430 .

[0152] The first holders 442 and the second holders 445 are spaced perpendicularly apart.

[0153] According to this configuration of this embodiment, it is advantageous that even if the battery cells ignite 430 in one of the two rows through the partition 441 This prevents the battery cells from... 430 ignite in the other row.

[0154] Furthermore, the partition wall allows 441 to prevent it from passing through the battery cells 430Heat generated in the two rows leads to mutual influence in other rows.

[0155] The structure and shape of the second holder 445 similar to the first holders 442 , so that only the first holders are listed below 442 will be described in more detail and for the construction and shape of the second holder 445 on the description of the first holders 442 is referred.

[0156] The first holders 442 can cell sleeves 442a , 442b , 443a , 443b and 443c exhibiting the upper sections of the battery cells 430 surrounded.

[0157] The battery cells 430 are spaced apart from each other, with the upper sections separated from the cell shells 442a , 442b , 443a , 443b and 443c are surrounded.

[0158] The cell shells 442a , 442b , 443a , 443band 443c may exhibit: first cell shells 442a and 442b , which cover the entire outer surfaces of some of the battery cells 430 surrounded, second cell shells 443a and 443b , which are the outer surfaces of some of the battery cells 430 partially surrounded, and a third cell shell 443c , which are between the two cell shells 443a and 443b is arranged.

[0159] For example, the first cell shells can 442a and 442b be cylindrical in shape, and the second cell shells 443a and 443b as well as the third cell shell 443c can be in a C-shape with an opening 443d be trained.

[0160] Two first cell shells are shown in more detail. 442a and 442b in contact with each other, with a first cell sleeve 442a a battery cell 430surrounds the first row and the other first cell shell 442b a battery cell 430 surrounds in the second row.

[0161] Furthermore, two second cell sleeves can be used. 443a and 443b with the partition wall 441 They should be horizontally spaced apart from each other and can be connected with connectors. 444a and 444b be connected.

[0162] The connectors 444a and 444b can create an initial connector 444a , which the two second cell shells 443a and 443b connects vertically, and a second connector 444b exhibiting a horizontal extension and the two second cell shells 443a and 443b connects. The second connector 444b can come into contact with the upper section of the partition 441 stand.

[0163] Through the connectors 444a and 444bare not just two spaced-apart second cell sleeves 443a and 443b connected, but the strength is improved.

[0164] The distance between the centers of the two second cell sleeves 443a and 443b is longer than the distance between the centers of the first two cell shells 442a and 442b .

[0165] The first cell shells 442a and 442b can be distinguished between two groups of second cell shells 443a and 443b be arranged.

[0166] This means that a second cell sleeve, a first cell sleeve, and a second cell sleeve can be arranged sequentially. According to this arrangement, the battery cells can be... 430 arranged in a zigzag pattern in each row, so that the horizontal length of the battery 40 It may be shortened.

[0167] Since the battery cells 430arranged in a zigzag pattern, this pattern also applies to an increasing number of battery cells. 430 the size of the battery 40 not so greatly enlarged, so that the maximum rechargeable voltage of the battery 40 It may be increased.

[0168] Even if, furthermore, two second cell shells 443a and 443b with the partition wall 441 are spaced apart from each other, the two second cell shells 443a and 443b , can the size of the first holder 442 be reduced in size, thus increasing the size of the frame 410 It may be reduced.

[0169] The third cell shell 443c is between two spaced-apart second cell shells 443a and 443b arranged. Therefore, according to the invention, the horizontal length of the battery can be 40 be smaller.

[0170] Fig. 14 is a top view of a second frame according to an embodiment of the invention, and Fig. Figure 15 is a top view after the battery holder and battery cells are seated inside the second frame.

[0172] The support flange 462 can extend from the underside of the second frame 460 extend horizontally outwards.

[0173] A coupling body 479 to couple the first coupling section 470 is on one side around the second frame 460 formed, and the second coupling section 474 is on another page around the second frame 460 educated.

[0174] The second frame 460 can also contact ribs 463 , 464 and 465 exhibiting those that come into contact with the components in the battery holder 440 held battery cells 430 stand.

[0175] The contact ribs 463 , 464 and 465 prevent horizontal movement of the battery cells 430 as part of 410 in contact with the battery cells 430 .

[0176] The contact ribs 463 , 464 and 465 may exhibit: first contact ribs 463 , which are at the corners of the second frame 460 are arranged, second contact ribs 464 , which come into contact with the battery cells 430 in the second cell shells 443a and 443b standing between the first cell shells 442a and 442b and the third cell shell 443c are arranged, and a third contact rib465 , which come into contact with the battery cell 430 in the third cell shell 443c stands.

[0177] As previously described, the second cell shells 443a and 443b as well as the third cell shell 443c the openings 443d have, lie in the fitting of the battery cells 430 in the second cell shells 443a and 443b as well as in the third cell shell 443c the battery cells 430 partially exposed to the outside, which is why the contact ribs 463 , 464 and 465 in contact with the battery cells 430 can come.

[0178] The contact ribs 463 , 464 and 465 can have a curvature corresponding to the curvature of the outer surfaces of the battery cells 430 be rounded to fit the battery cells 430 to maintain stable contact.

[0179] Is the battery holder 440within the second framework 460 arranged, a section of the battery holder 440 from the second frame 460 They must be spaced apart. Consequently, the space between the battery holder functions 440 and the second frame 460 as a heat dissipation space, so that heat is removed from the battery cells 430 is naturally derived.

[0215] In the invention, the wire grooves can 456 referred to as the first wire guides, and the wire holes 486 can be described as a second wire guide.

[0216] Fig. Figure 21 is a perspective view of the battery terminals according to an embodiment of the invention, and Fig. Figure 22 is a front view of a battery terminal of the invention.

[0217] According to Fig. 17, Fig. 21 and Fig. 22 can be a pair of battery terminals 490 directly on the circuit board481 be arranged.

[0218] The battery terminals 490 can be on the circuit board 481 Stand upright. The battery terminals 490 can be ahead 422 of the frame 410 may be arranged partially or completely.

[0219] Consequently, when inserting the battery vertically... 40 into the battery compartment 60 the second main body clamps 670 (see Fig. 23) with the battery terminals 490 be coupled.

[0220] The battery terminals 490 can each be a base 491 for installation on the circuit board 481 have.

[0221] The base 491 can accommodate multiple mounting pins 491a , 491b and 491c have the pin holes 483 the circuit board 481 through.

[0222] The mounting pins 491a , 491b and 491ccan a first pen 491a and a second pen 491b exhibiting points that are spaced apart from each other. The first pen 491a and the second pen 491b can be arranged in a way that points towards each other.

[0223] The mounting pins 491a , 491b and 491c can use a third pen 491c exhibiting which is arranged in such a way that it contains the first pin 491a and the second pen 491b in an area that corresponds to the area between the first pen 491a and the second pen 491b corresponds.

[0224] Are the battery terminals 490 on the circuit board 481 built-in and the circuit board 481 above the barrier 450 When installed, the deformation-preventing rib can 453 the lockdown 450 be positioned in an area between a line that marks the first pen 491a and the second pen 491bas well as the third pen 491c connects.

[0225] This makes it possible to prevent deformation of the circuit board. 481 to effectively prevent when the battery terminals 490 and the second main body clamps 670 (see Fig. 23) can be combined.

[0226] The battery terminals 490 Each pair of U-bolts can 492 and 493 have, which are derived from the base 491 extend upwards.

[0227] The clamps 492 and 493 can be a first clamp 492 and a second clamp 493 exhibit.

[0228] The first clamp 492 and the second clamp 493 can be based on 491 be elastically deformed, and the second main body clamp 670 (see Fig. 23) is in contact with the first clamp 492 and the second clamp 493between the first clamp 492 and the second clamp 493 .

[0229] So that the clamps 492 and 493 can be elastically deformed and the second main body clamp 670 (see Fig. 23) between the clamps 492 and 493 Once positioned, the clamps can 492 and 493 extend towards each other as they go upwards, and then extend away from each other at a predetermined height.

[0230] Since the directions of the clamps 492 and 493 The clamps can be changed. 492 and 493 Contact sections 497a or 497b have. That is, the first clamp. 492 can establish an initial contact phase 497a have, and the second clamp 493 can create a second contact section 497b have.

[0231] To ensure reliable contact between contact sections 497a and 497b the clamps 492 and 493 and the second main body clamp 670 (see Fig. 23) to improve, a section can be cut 494a and 494b for dividing the clamps 492 and 493 into several independent clamps on the U-bolt clamps 492 and 493 be educated.

[0232] Are the cut sections 494a and 494b on the clamps 492 and 493 In the invention, the number of independent clamps of the clamps is formed. 492 and 493 increased, thus improving the reliability of the contact with the second main body clamp 670 (see Fig. 23) is improved, but the contact surface with the second main body clamp 670 It is smaller, so that a short circuit can occur at high current.

[0233] Thus, the clamps 492 and 493 Each has two independent terminals. 495a , 495b , 496a and 496b , which are formed by the cut sections 494a or 494b are horizontally spaced apart from each other.

[0234] The first clamp 492 features a first independent terminal 495a and a second independent terminal 495b up, and the second clamp 403 features a third independent terminal 496a and a fourth independent terminal 496b on.
