Description

Dehydration device Field of invention

The present invention relates to a dewatering apparatus for dehydrating laundry.

Description of the background

A typical dewatering unit containing a dewatering tank useful for dewatering laundry. The dewatering tank generally has an inner tank that rotates to dehydrate the laundry, and an outer tank that accommodates the inner tank. A plurality of through holes are formed in the peripheral wall of the inner groove. The water removed from the laundry dewatering is discharged from the inner tank through the through hole. The outer tank receives water discharged from the inner tank.

The laundry to be subjected to dehydration treatment is heavy due to water content. By the rotation of the inner groove, the laundry collides with the peripheral wall of the inner groove, thereby promoting the purpose of dehydration. On the other hand, the collision between the laundry and the peripheral wall of the inner tank causes vibration of the dewatering tank.

The various types of dehydration devices include a large-amplitude switching element for detecting a dewatering tank (for example, refer to Japanese Patent Laid-Open Publication No. Hei. No. Hei. No. Hei. No. Hei. Japanese Patent Laid-Open Publication No. Hei No. 3-70595, Japanese Patent Laid-Open Publication No. Hei No. Hei No. Hei No. Hei No. Hei. When the dewatering tank is largely displaced, the switching element is actuated and the inner groove stops rotating.

In addition, the existing dehydration device uses an acceleration sensor instead of the switching element to detect the vibration of the dewatering tank (for example, refer to Japanese Patent Laid-Open Publication No. 5-237290, Japanese Patent Laid-Open Publication No. Hei 10-43469). The acceleration sensor detects the vibration of the dewatering tank at a high speed rotation that is difficult to detect by the switching element.

The distribution of clothing in the dewatering tank varies randomly. Therefore, the aforementioned acceleration sensor and switching element cannot detect the vibration immediately due to the distribution of the clothes.

Summary of invention

It is an object of the present invention to provide a dewatering apparatus which can instantly detect the vibration of a dewatering tank.

A dehydration device according to an embodiment of the present invention includes: a dewatering tank that rotates to dehydrate the laundry; and a sensor unit that outputs a detection signal including information on the vibration of the dewatering tank; and a control device, Controlling the dewatering tank according to the detection signal, and the sensor unit has: a first sensor element for detecting an amplitude of the first direction of the dewatering tank; and a second sensor element The first sensor element is disposed in a second direction opposite to the first direction.

The dehydration device of the present invention can instantly detect the vibration of the dewatering tank.

When the drain valve 320 opens the drain pipe 310, the water in the outer tank 220 is discharged to the outside of the casing 110 through the drain pipe 310.

As shown in FIGS. 1 and 5, the treatment tank 200 has a substantially disk-shaped rotary disk 230. The turntable 230 has a circular plate portion 231 that spans the bottom wall 212 of the inner groove 210, and a tilt ring 232 that protrudes upward from the peripheral edge of the circular plate portion 231. The tilt ring 232 expands upward. The turntable 230 further has a stirring rib 233 protruding from the upper surface of the circular plate portion 231 and the inclined ring 232. The agitating ribs 233 extend radially. The turntable 230 rotates during washing of the laundry and/or during drying of the laundry. Therefore, the laundry is appropriately stirred during the aforementioned steps.

The washing machine 100 further includes a drive mechanism 400 that selectively rotates the inner tank 210 and the rotary disk 230 under the control of the control device 150. The drive mechanism 400 has a drive motor 410 that generates a driving force for rotating the inner groove 210 or the rotary disk 230, a first shaft 420 connected to the inner groove 210, and a second shaft 430 connected to the rotary disk 230. And the clutch device 440 transmits the driving force of the drive motor 410 between the first shaft 420 and the second shaft 430. The drive motor 410 and the clutch device 440 that operate under the control of the control device 150 are fixed to the bottom wall 222 of the outer tub 220. The first shaft 420 penetrates the bottom wall 222 of the outer tank 220 and is connected to the bottom wall 212 of the inner tank 210. The second shaft 430 that is concentrically rotated with the first shaft 420 protrudes from the first shaft 420 and is connected to the rotary disk 230 of the inner tub 210. In the present embodiment, the drive motor 410 is exemplified as a drive source.

When the washing step for washing the laundry is performed, the clutch device 440 switches the transmission path of the driving force to transmit the driving force to the second shaft 430. So, wash In the step, the rotary disk 230 rotates in the inner groove 210.

As shown in FIG. 1, the washing machine 100 further includes a water supply system 500 that supplies water for washing laundry to the treatment tank 200. The water supply system 500 includes a water supply unit 510 that is attached to a water supply port 501 (see FIG. 3) formed on the top wall 131 of the upper casing 130, and a switching valve 520 that switches the path of water supplied from the water supply unit 510. And the water supply pipe 530 is a path that defines water flowing from the switching valve 520 toward the outer groove 220.

The water supply unit 510 is connected to, for example, a tap (not shown) of tap water. When the switching valve 520 opens the water path toward the water supply pipe 530, water is supplied to the treatment tank 200.

As shown in Fig. 5, the treatment tank 200 has a recovery bag 214 for intercepting and recovering lint separated from laundry during washing, and a fluid balancer 215 for functioning to maintain the balance of the inner tank 210. A recovery bag 214 and a fluid balancer 215 are mounted on the upper edge of the inner tank 210.

As shown in FIG. 1, the outer groove 220 further has an upper plate 227 connected to the upper edge 224 of the peripheral wall 221 and spanning the inner groove 210, and an inner cover 229 mounted to be movable up and down with respect to the upper plate 227.

Alternatively, the user can take the laundry out of the inner tub 210. When the user rotates the inner cover 229 to the lower side, a sealing structure is formed between the upper plate 227 and the inner cover 229. Therefore, the water in the treatment tank 200 leaks almost or completely from the opening of the upper plate 227.

The washing machine 100 further includes a circulation system 600 that circulates dry air for drying the laundry. The circulation system 600 has a heat exchanger 610, a tube And connected to the connecting conduit 226; and the guiding tube 611 guides the water from the switching valve 520 toward the heat exchanger 610. When the switching valve 520 opens the water path toward the guide tube 611, water is supplied to the heat exchanger 610.

The heat exchanger 610 has an end portion 612 connected to the connecting duct 226, and an upper end portion 613 connected to the guiding tube 611. The dry air flowing upward is heat-exchanged with water flowing in from the upper end portion 613 of the heat exchanger 610. Thus, the dry air can be appropriately dehumidified.

The circulation system 600 further has a cooling fan 620 mounted on the back wall 123. The cooling fan 620 blows air toward the heat exchanger 610 to cool the dry air. Thus, dehumidification of the dry air is promoted.

The circulation system 600 has a blower fan 630 that sends the dehumidified dry air to the treatment tank 200, a heater 640 that heats the dry air between the blower fan 630 and the treatment tank 200, and an introduction tube 650. The heated dry air is directed to the treatment tank 200. The introduction tube 650 is connected to the upper plate 227. The circulation system 600 can feed dry air into the treatment tank 200 through the introduction pipe 650, and recover the dry air through the connection pipe 226. Thus, the circulation of the dry air around the treatment tank 200 is achieved.

The washing machine 100 further includes a suspension unit 240 that connects the housing 110 and the outer slot 220. The suspension unit 240 supporting the outer tank 220 can attenuate the vibration transmitted from the outer tank 220 toward the casing 110.

Fig. 6 is a schematic enlarged plan view of the periphery of a corner portion between the front wall 124 and the right wall 126. The washing machine 100 will be further described with reference to Figs. 1, 2, 4, and 6.

The turntable 230, the inner groove 210 and the outer groove 220 are arranged to be slightly concentric. In off In the water step, the heavier water-containing clothes collide with the peripheral wall 211 of the inner tank 210. Or, the clothes may be unevenly distributed. The collision of the clothes and/or the unevenness of the cloth will cause the vibration of the treatment tank 200.

The peripheral wall 221 of the outer groove 220 has an inner surface 241 opposed to the peripheral wall 211 of the inner groove 210, and an outer surface 242 located on the opposite side to the inner surface 241. The outer surface 242 is opposed to the side wall portion 121. As shown in FIG. 6, the outer surface 242 is adjacent to the side wall portion 121.

The washing machine 100 further includes an acceleration sensor 700. The acceleration sensor 700 mounted on the outer surface 242 of the peripheral wall 221 detects the acceleration of the outer surface 242 as information about the vibration of the dewatering tank. Further, the acceleration sensor 700 outputs a detection signal corresponding to the acceleration of the outer surface 242 to the control device 150. In this embodiment, the acceleration sensor 700 and the switching element 152 described in connection with FIG. 4 are both used as sensor units. Further, the acceleration sensor 700 is exemplified as a second sensor element.

The acceleration sensor 700 preferably detects at least one of an acceleration component of the radial direction of the outer groove 220 and an acceleration component of the circumferential direction of the outer groove 220. Therefore, the vibration of the outer tank 220 can be appropriately measured. Preferably, the acceleration sensor 700 detects the up-and-down direction (ie, the radial direction of the outer groove 220 and the circumferential direction of the outer groove 220) in addition to the acceleration component of the radial direction of the outer groove 220 and the acceleration component of the circumferential direction of the outer groove 220. The acceleration component of the direction of the orthogonal direction. Therefore, the control device 150 can appropriately analyze the vibration mode of the outer slot 220 according to the detection signal from the acceleration sensor 700.

The acceleration sensor 700 is disposed at a corner portion surrounded by the outer groove 220, the front wall 124, and the right wall 126. Since it is formed in a space between the slightly cylindrical outer groove 220 and the slightly rectangular cylindrical side wall portion 121, it is suitable for the acceleration sensor With the configuration of 700, there is no need to ensure additional space for the configuration of the acceleration sensor 700. Therefore, the present invention can provide a small washing machine 100.

As described in connection with FIG. 4, the switching element 152 is disposed at a corner portion between the back wall 123 and the left wall 125. On the other hand, the acceleration sensor 700 is disposed between the front wall 124 and the right wall 126. Therefore, the acceleration sensor 700 is disposed on a diagonal line of the housing 110 with respect to the switching element 152 (ie, in the second direction SD with respect to the switching element 152).

As shown in Fig. 6, if the processing tank 200 is rotated in the clockwise direction, the vibration of the processing tank 200 between the right wall 126 and the back wall 123 is uneven due to the unevenness of the laundry and/or the collision of the processing tank 200. The detector 700 detects. The vibration of the treatment tank 200 due to the unevenness of the laundry between the left wall 125 and the front wall 124 is detected by the switching element 152. Therefore, the vibration of the processing tank 200 is detected by at least one of the acceleration sensor 700 and the switching element 152 within a period of one half rotation of the processing tank 200. Thus, the vibration of the processing tank 200 can be quickly detected.

The control device 150 analyzes the vibration mode of the processing tank 200 based on the detection signals output from the switching element 152 and the acceleration sensor 700. If the amplitude of the processing tank 200 exceeds a threshold determined for the amplitude, the control device 150 reduces the rotational speed of the drive motor 410. Alternatively, control device 150 will cause drive motor 410 to stop. Therefore, the amount of movement of the treatment tank 200 is lowered, and the amplitude of the treatment tank 200 becomes small.

As shown in FIG. 6, the outer surface 242 of the outer groove 220 is adjacent to the side wall portion 121. As described above, the acceleration sensor 700 and the switching element 152 can quickly detect the vibration of the processing tank 200, so the outer surface 220 of the outer groove 220 and the side wall portion 121 Even if the space between them is narrow, collision between the outer groove 220 and the side wall portion 121 can be avoided or reduced. Therefore, the present invention can provide a small washing machine 100.

The acceleration sensor 700 is preferably mounted adjacent the upper edge 224 of the outer slot 220. When the operator wants to adjust or repair the acceleration sensor 700, the upper housing 130 is separated from the lower housing 120, and the acceleration sensor 700 installed near the upper edge 224 of the outer groove 220 can be easily accessed. Therefore, the repair, installation or removal of the acceleration sensor 700 can be easily performed. Moreover, since the amplitude of the upper edge 224 of the outer groove 220 is large, the acceleration sensor 700 installed near the upper edge 224 of the outer groove 220 can appropriately detect the acceleration of the outer groove 220.

Fig. 7 is a schematic perspective view of a heat exchanger 610 mounted on a housing 110. Fig. 8 is a schematic enlarged plan view showing the vicinity of a corner portion between the right wall 126 and the back wall 123. The mounting of the heat exchanger 610 will be described using Figs. 1, 7 and 8.

The housing 110 further has a back cover 129 mounted to the back wall 123. The heat exchanger 610 is erected between the back cover 129 and the back wall 123. As shown in Fig. 8, the heat exchanger 610 is disposed near the right wall 126. Therefore, the circulation system 600 described in connection with Fig. 1 is eccentrically disposed at the right wall 126 with respect to the center of rotation of the processing tank 200.

The circulation system 600 is connected to the upper surface of the treatment tank 200 (i.e., the upper plate 227) and the lower surface (i.e., the bottom wall 222 of the outer tank 220) in the vicinity of the right wall 126. Further, the heat exchanger 610 extends upward along the back wall 123 and the back cover 129. Therefore, the circulation system 600 suppresses the displacement of the treatment tank 200 in the up-and-down direction centering on the vicinity of the corner portion between the right wall 126 and the back wall 123. In this embodiment, Ring system 600 is illustrated as a suppression unit.

On the other hand, in the vicinity of the corner portion between the left wall 125 and the front wall 124 on the diagonal line between the corner portion between the right wall 126 and the back wall 123, the processing tank 200 is relatively easy to move up and down. For example, when the user spills water on the upper plate 227, the water will thus flow toward the corner between the left wall 125 and the front wall 124. In this embodiment, since there is no sensor unit of the acceleration sensor 700 and the switching element 152 at the corner between the left wall 125 and the front wall 124, there is almost no overflow from the upper plate. The water on 227 causes a situation in which the sensor unit of the acceleration sensor 700 and the switching element 152 fails. Therefore, the present invention can provide the washing machine 100 of high reliability.
