Description
本發明係有關一種驅動滾筒式洗衣機之旋轉滾筒的馬達之驅動滑輪與皮帶的構成。The present invention relates to a drive pulley and a belt for driving a motor of a rotary drum of a drum type washing machine.
習知，例如在特開2009-78056號公報(以下記為「專利文獻1」)中，揭示有將固著於水槽之外底部之馬達的旋轉，從形成於馬達軸之驅動滑輪或是固著於馬達軸之驅動滑輪透過皮帶，而傳達至直接連結於旋轉滾筒之從動滑輪，來作為驅動滾筒式洗衣機之旋轉滾筒的構成。For example, JP-A-2009-78056 (hereinafter referred to as "Patent Document 1") discloses a rotation of a motor fixed to a bottom portion of a water tank, and a driving pulley formed on a motor shaft or a solid. The drive pulley of the motor shaft is transmitted through the belt to the driven pulley directly coupled to the rotary drum to constitute a rotary drum for driving the drum type washing machine.
以下，就有關記載於專利文獻1之習知滾筒式洗衣機的構成，利用第4圖來進行說明。第4圖係習知滾筒式洗衣機之縱斷面圖。Hereinafter, the configuration of the conventional drum type washing machine described in Patent Document 1 will be described with reference to FIG. Figure 4 is a longitudinal sectional view of a conventional drum type washing machine.
如第4圖所示，習知之滾筒式洗衣機在洗衣機本體31內部具有水槽32，在水槽32內部，旋轉滾筒33係正轉、逆轉等可自由旋轉地軸支撐於旋轉軸35。複數脫水運轉時之排水用的小孔41設於旋轉滾筒33之外周壁，而在內周壁設有複數個衣服攪拌用隔板36。設於旋轉滾筒33之衣服攪拌用隔板36在洗滌行程中，藉由低速的正旋轉、逆旋轉(例如50rpm)進行衣服的攪拌，且在脫水行程中以高速之單方向旋轉(例如1000rpm)而從衣服離心分離水分。As shown in Fig. 4, a conventional drum type washing machine has a water tank 32 inside the washing machine body 31, and inside the water tank 32, the rotary drum 33 is rotatably supported by the rotating shaft 35 so as to be rotatable and reversed. The small holes 41 for drainage during the plurality of dehydration operations are provided on the outer peripheral wall of the rotary drum 33, and a plurality of clothes agitating partitions 36 are provided on the inner peripheral wall. The clothes stirring separator 36 provided in the rotary drum 33 performs the stirring of the clothes by the low-speed positive rotation, the reverse rotation (for example, 50 rpm) during the washing stroke, and rotates in a single direction at a high speed in the dehydration stroke (for example, 1000 rpm). The water is separated from the clothes by centrifugation.
又，在第4圖所示之旋轉滾筒33的右端部固著有旋轉軸35，在旋轉軸35之右端部固著有從動滑輪37。水槽32之外底部設有馬達20，且在馬達20之馬達軸39端部形成有複數條V溝43(在第5圖後述)。且，馬達20之馬達軸39與從動滑輪37之間伸張設有具複數條V狀溝42(在第5圖後述)的皮帶38。Further, a rotating shaft 35 is fixed to the right end portion of the rotary drum 33 shown in FIG. 4, and a driven pulley 37 is fixed to the right end portion of the rotating shaft 35. A motor 20 is provided at the bottom of the water tank 32, and a plurality of V grooves 43 (described later in Fig. 5) are formed at the end of the motor shaft 39 of the motor 20. Further, a belt 38 having a plurality of V-shaped grooves 42 (described later in FIG. 5) is stretched between the motor shaft 39 of the motor 20 and the driven pulley 37.
又，洗衣機本體31上方設有組入了自開關(未圖示)等接收輸入訊號之微電腦(未圖示)等之控制部34。控制部34控制自洗滌行程到脫水行程等之一連串的行程，且進行馬達20之在洗滌行程的低速旋轉及在脫水行程之高速旋轉等切換控制。Further, a control unit 34 such as a microcomputer (not shown) that receives an input signal such as a switch (not shown) is disposed above the main body 31 of the washing machine. The control unit 34 controls a series of strokes from the washing stroke to the dehydration stroke, and performs switching control such as low-speed rotation of the washing stroke of the motor 20 and high-speed rotation of the dehydrating stroke.
以下，就有關習知滾筒式洗衣機之馬達的馬達軸與皮帶之構成，使用第5圖進行說明。第5圖係說明習知滾筒式洗衣機之馬達的馬達軸附近(第4圖之B部)之構成的重要部分放大圖。Hereinafter, the configuration of the motor shaft and the belt of the motor of the conventional drum type washing machine will be described using FIG. Fig. 5 is an enlarged view of an essential part showing a configuration of a vicinity of a motor shaft (portion B in Fig. 4) of a motor of a conventional drum type washing machine.
如第5圖所示，以具有強度及剛性之鋼材所形成之馬達軸39之前端部附近的外周，形成有對應皮帶38之V狀溝42而嵌合之複數條V溝43。此時，以馬達軸39之複數條V溝43的外徑D2與馬達軸39之直徑D1大致相同(包含相同)，而形成有V溝43。因此，不須以其他構件構成驅動滑輪等並安裝於馬達軸39，而可以小直徑之馬達軸39實現驅動側之滑輪。其結果，即使從動滑輪37之外徑較小，也可使馬達軸39與從動滑輪37之減速比(從動滑輪37之直徑/馬達軸39之直徑)較大。As shown in Fig. 5, a plurality of V grooves 43 that are fitted to the V-shaped grooves 42 of the belt 38 are formed on the outer periphery of the vicinity of the front end portion of the motor shaft 39 formed of a steel material having strength and rigidity. At this time, the outer diameter D2 of the plurality of V grooves 43 of the motor shaft 39 is substantially the same as the diameter D1 of the motor shaft 39 (including the same), and the V groove 43 is formed. Therefore, it is not necessary to form a drive pulley or the like with another member and attach it to the motor shaft 39, and the drive shaft pulley can be realized by the motor shaft 39 having a small diameter. As a result, even if the outer diameter of the driven pulley 37 is small, the reduction ratio of the motor shaft 39 and the driven pulley 37 (the diameter of the driven pulley 37 / the diameter of the motor shaft 39) can be made large.
如以上所說明的，習知之滾筒式洗衣機藉由馬達20旋轉數之切換控制，以一個減速比透過皮帶38而將馬達20之旋轉傳達至旋轉滾筒33。藉此，於洗滌行程、脫水行程中，可進行旋轉滾筒33之旋轉驅動。As described above, the conventional drum type washing machine transmits the rotation of the motor 20 to the rotary drum 33 through the belt 38 at a reduction ratio by the switching control of the number of rotations of the motor 20. Thereby, the rotational driving of the rotary drum 33 can be performed in the washing stroke and the dehydration stroke.
但是，於習知之構成中，為了更加大減速比，必須使成為馬達側之驅動滑輪之馬達軸39的外徑更小。其結果，皮帶38與馬達軸39之V溝43之周速度變得更高速。However, in the conventional configuration, in order to increase the reduction ratio, it is necessary to make the outer diameter of the motor shaft 39 which is the drive pulley on the motor side smaller. As a result, the peripheral speed of the belt 38 and the V groove 43 of the motor shaft 39 becomes higher.
一般來說，皮帶38係使具耐熱性、耐磨耗性等之合成橡膠構成為主體，並具有大的摩擦力。因此，皮帶38之V狀溝42與設於馬達軸39之前端部附近之外周的V溝43以高速之周速度反覆密接、脫離。其結果，發生因高速之密接、脫離所產生之滑動聲，而於洗滌運轉中有所謂作為異聲對使用者給予不快感的課題。In general, the belt 38 is formed of a synthetic rubber having heat resistance, abrasion resistance, and the like as a main body, and has a large frictional force. Therefore, the V-shaped groove 42 of the belt 38 and the V groove 43 provided on the outer periphery of the vicinity of the front end portion of the motor shaft 39 are repeatedly brought into close contact with each other at a high speed. As a result, there is a problem that the sliding sound generated by the high-speed close contact and the detachment occurs, and in the washing operation, there is a problem that the user feels unpleasant as a strange sound.
又，將低溫之洗滌水供給至水槽32時，包含於洗衣機本體31內部之空氣的水分(水蒸氣)凝結(結露)於水槽32等之外壁，有滴下於皮帶38之V狀溝42與馬達軸39之V溝43的滑動部而附著的情況。此時，皮帶38之V狀溝42與馬達軸39之V溝43的周速度低時，一些水分即使附著於滑動部也不會對朝旋轉滾筒33之旋轉傳達力造成大影響。但是，如習知例般，驅動側之滑輪為馬達軸時，由於馬達軸的直徑小周速度變快，所以皮帶38的V狀溝42與馬達軸39的V溝43之間發生滑動(slip)。因此，變得無法將馬達20之旋轉正確地朝旋轉滾筒33傳達。其結果，而有所謂在洗滌行程及脫水行程之性能降低的問題。When the low-temperature washing water is supplied to the water tank 32, the moisture (water vapor) of the air contained in the inside of the washing machine body 31 is condensed (condensed) on the outer wall of the water tank 32, and the V-shaped groove 42 and the motor dropped on the belt 38. The sliding portion of the V groove 43 of the shaft 39 is attached. At this time, when the peripheral speed of the V-groove 42 of the belt 38 and the V-groove 43 of the motor shaft 39 is low, some moisture does not greatly affect the rotational transmission force of the rotary drum 33 even if it adheres to the sliding portion. However, as in the case of the conventional example, when the pulley on the drive side is a motor shaft, since the diameter of the motor shaft is small, the speed is fast, so that the V-shaped groove 42 of the belt 38 and the V groove 43 of the motor shaft 39 slide (slip). ). Therefore, it becomes impossible to accurately convey the rotation of the motor 20 toward the rotary drum 33. As a result, there is a problem that the performance of the washing stroke and the dehydration stroke is lowered.
本發明之滾筒式洗衣機包含有支持於洗衣機本體內之水槽、支持於水槽內之旋轉滾筒、固著於水槽之外底部之馬達、設於馬達之馬達軸端之驅動滑輪、將一端固著於旋轉滾筒之旋轉軸、固設於旋轉軸之另一端之從動滑輪、及將馬達之旋轉傳達至從動滑輪之皮帶，且具有將被覆驅動滑輪之外周的防水罩固著於馬達之構成。The drum type washing machine of the present invention comprises a water tank supported in the washing machine body, a rotating drum supported in the water tank, a motor fixed to the bottom of the water tank, a driving pulley provided on the motor shaft end of the motor, and one end fixed to the motor A rotating shaft of the rotating drum, a driven pulley fixed to the other end of the rotating shaft, and a belt for transmitting the rotation of the motor to the driven pulley, and having a waterproof cover that covers the outer circumference of the driving pulley is fixed to the motor.
藉此，防止由驅動滑輪與皮帶之滑動摩擦而發生之異聲的擴散。又，可防止凝結於水槽等外壁之水分朝驅動滑輪與皮帶之滑動部附著所產生之「滑動」的發生。其結果，可防止洗滌行程及脫水行程中旋轉滾筒之旋轉數等之變動所產生之洗滌性能的降低。Thereby, the diffusion of the strange sound generated by the sliding friction between the driving pulley and the belt is prevented. Further, it is possible to prevent the occurrence of "sliding" caused by moisture adhering to the outer wall of the water tank or the like to the sliding portion of the driving pulley and the belt. As a result, it is possible to prevent a decrease in the washing performance due to fluctuations in the number of rotations of the rotary drum during the washing stroke and the dehydrating stroke.

Fig. 3 is a sectional view taken along line 3-3 of the drum type washing machine in the B direction shown in Fig. 2;
如第2圖所示，本實施形態之滾筒式洗衣機係於馬達20之馬達軸39之前端部，固著有具伸張設有皮帶38之複數V溝43的驅動滑輪2。且，固著於馬達軸39之驅動滑輪2外周設有被覆驅動滑輪2周圍的防水罩1。防水罩1係例如以塑膠成型構件形成，並以將開口部3設於皮帶38通過之位置的例如斷面形狀為略字狀(包含字狀)的圓筒形狀而形成。As shown in Fig. 2, the drum type washing machine of the present embodiment is attached to the front end portion of the motor shaft 39 of the motor 20, and a drive pulley 2 having a plurality of V grooves 43 provided with a belt 38 is fixed. Further, a waterproof cover 1 around the drive drive pulley 2 is provided on the outer circumference of the drive pulley 2 fixed to the motor shaft 39. The waterproof cover 1 is formed, for example, by a plastic molding member, and is, for example, a cross-sectional shape in which the opening portion 3 is provided at a position where the belt 38 passes. Font (including The shape of the shape of the cylinder is formed.
又，防水罩1在馬達20側具有複數個例如L字形之爪片4。且，藉由將爪片4卡固於馬達20之前板5的小孔8，而定位防水罩1與馬達。再者，複數個安裝座6與圓筒部1a一體形成於防水罩1之圓筒部1a外周的馬達20側，且例如藉由小螺絲7等而螺固於馬達20之前板5。Further, the waterproof cover 1 has a plurality of claw pieces 4, for example, L-shaped on the motor 20 side. Further, the waterproof cover 1 and the motor are positioned by engaging the claw piece 4 to the small hole 8 of the front plate 5 of the motor 20. Further, a plurality of mounts 6 and the cylindrical portion 1a are integrally formed on the motor 20 side of the outer circumference of the cylindrical portion 1a of the waterproof cover 1, and are screwed to the front plate 5 of the motor 20 by, for example, a small screw 7 or the like.
又，例如不織布等所產生之毛氈、發泡體及多孔質體等之吸音材9，藉由嵌入或是接著而裝設於防水罩1之圓筒部1a的內周部。Further, for example, a sound absorbing material 9 such as a felt, a foam, or a porous body which is produced by a nonwoven fabric or the like is attached or attached to the inner peripheral portion of the cylindrical portion 1a of the waterproof cover 1.
又，於防水罩1之字狀右側(在第2圖所示之右側面側)設有連接於皮帶38通過之開口部3的側面開口10。透過設於防水罩1之側面開口10，而可觀察皮帶38朝固著於馬達軸39之驅動滑輪2的安裝、皮帶38之V狀溝42與驅動滑輪2之V溝43之滑動狀態的觀察、及皮帶38之張力等之變化所產生之鬆弛等。Also, in the waterproof cover 1 The right side of the font (on the right side side shown in Fig. 2) is provided with a side opening 10 that is connected to the opening 3 through which the belt 38 passes.

Therefore, the sound absorbing material 9 is attached to the entire inner circumferential surface of the cylindrical portion 1a of the waterproof cover 1 except for the two opening portions 3.
又，在防水罩1之皮帶38通過之開口部3的上方側面，肋體11一體設於與馬達軸39之延伸方向相同的方向。藉此，可防止凝結(結露)於水槽等之水分滴下到防水罩1之上面12，並從開口部3朝防水罩1內部之皮帶38的V狀溝42與驅動滑輪2之V溝43的滑動部分侵入。Moreover, the rib 11 is integrally provided in the same direction as the extending direction of the motor shaft 39 on the upper side surface of the opening 3 through which the belt 38 of the waterproof cover 1 passes. Thereby, it is possible to prevent condensation (condensation) of water in the water tank or the like from dropping onto the upper surface 12 of the waterproof cover 1, and from the opening portion 3 toward the V-shaped groove 42 of the belt 38 inside the waterproof cover 1 and the V groove 43 of the drive pulley 2 The sliding part invades.

Moreover, the occurrence of echo or the like can be remarkably suppressed.
又，依據本實施形態之滾筒式洗衣機，皮帶38之V狀溝42與驅動滑輪2之V溝43的滑動部之周圍，除了開口部3，以防水罩1被覆。因此，可有效地降低凝結(結露)於外槽32等之外壁而滴下的水分朝滑動部的侵入。藉此，可防止發生皮帶38之V狀溝42與驅動滑輪2之V溝43的滑動。其結果，可防止洗滌行程及脫水行程中旋轉滾筒33之旋轉數等之變動所產生之洗滌性能的降低。Further, according to the drum type washing machine of the present embodiment, the periphery of the sliding portion of the V-shaped groove 42 of the belt 38 and the V groove 43 of the drive pulley 2 is covered with the waterproof cover 1 except for the opening portion 3. Therefore, it is possible to effectively reduce the intrusion of moisture that has condensed (condensed) on the outer wall of the outer tub 32 and the like to the sliding portion. Thereby, the sliding of the V-shaped groove 42 of the belt 38 and the V groove 43 of the drive pulley 2 can be prevented. As a result, it is possible to prevent a decrease in the washing performance due to fluctuations in the number of rotations of the rotary drum 33 during the washing stroke and the spin-drying stroke.
