Description

  The present invention relates to a detergent container for holding a detergent in a washing machine.

  A washing machine typically includes a housing and a detergent container that holds detergent in the housing (see, for example, Patent Documents 1 to 3). The washing machine further includes a washing tub for washing clothes, a supply device (for example, a pump) for supplying detergent from the detergent container to the washing tub, and a control device for controlling operations of the washing tub and the supply device. . The supply device supplies the detergent to the washing tub under the control of the control device.

  The above-described screw-type connection structure tends to cause insufficient lid tightening. For example, even if the lid is attached obliquely with respect to the input portion, the user often does not notice improper attachment of the lid.

  Detergents, particularly liquid detergents, act as lubricants that reduce the frictional force between the lid and the input. If the user inadvertently attaches the liquid detergent to the outer surface of the charging unit, the screwing of the lid to the charging unit is likely to loosen. If the attachment of the lid to the charging portion is incomplete or inappropriate, the screw and the charging portion are more easily loosened as a result of adhesion of the liquid detergent to the outer surface of the charging portion.

Therefore, the liquid detergent adhering to the outer surface of the charging part tends to stay in a slight gap between the lid and the charging part. The vibration transmitted from the washing tub to the detergent container while the washing tub is being driven, coupled with the liquid detergent on the outer surface of the dosing section that potentially acts as a lubricant, The loosening of the joint will be promoted.

  The supply device often increases the pressure in the detergent container and supplies the detergent to the washing tub. As described above, if the screwing between the lid and the charging portion is loose, the detergent leaks out of the detergent container as a result of the increase in the internal pressure of the detergent container. The leakage of the detergent results in a failure of the washing machine or contamination around the washing machine.

(Washing machine overall configuration)
FIG. 1 is a schematic longitudinal sectional view of a washing machine incorporating a detergent container. The washing machine will be described with reference to FIG. The washing machine shown in FIG. 1 has not only a washing function for washing clothes, but also a drying function for drying clothes. Alternatively, the detergent container may be incorporated into a washing machine that does not have a drying function.

  The washing machine 100 includes a substantially rectangular box-shaped casing 110, an outer tub 120 disposed in the casing 110, and a plurality of suspensions 130 that elastically support the outer tub 120. In order to avoid unnecessarily obscuring the drawing, only one suspension 130 is shown in FIG. The suspension 130 attenuates vibration from the outer tub 120 in a washing process for washing clothes and a dehydration process for dehydrating clothes. Therefore, vibration is hardly transmitted to the housing 110.

  The housing 110 includes a lower housing 111 that surrounds the outer tub 120, and an upper housing 112 that is disposed above the outer tub 120. The upper housing 112 includes a lid body 113 that can be turned up and down. The user can open the lid 113 and put clothes into the housing 110.

  The washing machine 100 further includes an inner tub 140 disposed in the outer tub 120. The outer tub 120 includes a bottom wall 121 that extends substantially horizontally and a substantially cylindrical peripheral wall 122 that stands upright from the bottom wall 121. The inner tank 140 includes a bottom wall 141 along the bottom wall 121 of the outer tank 120 and a peripheral wall 142 surrounded by the peripheral wall 122 of the outer tank 120. A large number of openings 143 are formed in the peripheral wall 142 of the inner tank 140.

  The user can store clothing in the inner tub 140. During the dehydration process, the water dehydrated from the clothes escapes from the inner tub 140 through the opening 143. In addition, during the washing process, washing water for dehydrating clothes flows into the inner tub 140 through the opening 143.

  The washing machine 100 further includes a fluid balancer 144 attached to the upper part of the peripheral wall 142 of the inner tub 140. The fluid balancer 144 balances the inner tank 140 during rotation.

  The washing machine 100 is attached to a shaft mechanism 150 that penetrates the bottom walls 121 and 141 of the outer tub 120 and the inner tub 140, a pulsator 151 attached to the upper end of the shaft mechanism 150, and an outer surface of the bottom wall 121 of the outer tub 120.

The shaft 153 includes a first shaft 155 connected to the bottom wall 141 of the inner tank 140, and a second shaft 156 connected to the pulsator 151 that extends radially on the bottom wall 141 of the inner tank 140. The clutch 154 switches the transmission of the driving force from the driving motor 152 between the first shaft 155 and the second shaft 156.

  The substantially dish-shaped pulsator 151 includes a support disc 157 that supports clothing put in the inner tub 140 and an inclined plate 158 that extends upward from the support disc 157. The inclined plate 158 includes an inclined surface 159 that expands radially. The pulsator 151 further includes a stirring rib 149 provided upright from the upper surface of the support disk 157 and the inclined surface 159. The stirring ribs 149 extend radially.

  In the washing process, the clothes stored in the inner tub 140 are stirred by the stirring rib 149. In the drying process, the clothes are rolled by the stirring rib 149 and are urged to the inclined surface 159 by the centrifugal force caused by the rotation of the pulsator 151. Thereafter, the garment is guided by the inclined surface 159 and is flipped upward.

  The drive motor 152 can rotate the pulsator 151 in both directions. The clothing performs a complicated motion in the inner tub 140 due to the switching of the rotation direction of the pulsator 151 and the above-described flip-up action.

  An opening 123 is formed in the bottom wall 121 of the outer tub 120. Washing water and dry air are discharged from the outer tub 120 through the opening 123. The washing machine 100 further includes a connection duct 131 connected to the opening 123.

  The outer tub 120 further includes a cover member 124 that closes an opening defined by the upper edge of the peripheral wall 122. The cover member 124 is formed with an air supply port 125 for introducing dry air into the outer tub 120. The cover member 124 includes an inner lid 126. The user can open the lid body 113 and the inner lid 126 and put the clothes into the inner tub 140.

  The washing machine 100 further includes a circulation system 200 for circulating dry air between the opening 123 and the air supply port 125. The circulation system 200 includes a tubular heat exchanger 210 that exchanges heat with dry air. The heat exchanger 210 includes a lower end connected to the connection duct 131.

  Dry air obtained by drying the clothes in the inner tub 140 flows into the heat exchanger 210 through the connection duct 131. The heat exchanger 210 is supplied with dehumidified water for dehumidifying the dry air. While being guided upward by the heat exchanger 210, the dry air is dehumidified by dehumidified water.

  The circulation system 200 further includes a processing unit 220 that performs various processes such as a dust removal process, a blowing process, and a heating process on the dehumidified dry air. The processing unit includes, for example, a filter device (not shown) for removing lint contained in the dry air, a blower device (not shown) that re-feeds the dehumidified dry air into the outer tank 120, and a blower device and the outside. You may provide the heater (not shown) which heats dry air between the tanks 120. FIG. The upper end of the heat exchanger 210 is connected to the processing unit 220.

  The circulation system 200 further includes a connection hose 230 that connects the processing unit 220 and the air supply port 125. Thus, the dry air can circulate between the air inlet 125 and the opening 123.

  The washing machine 100 further includes a water supply system 300 for supplying washing water to the inner tub 140. The water supply system 300 includes a water supply port 310, a water supply valve 320 for controlling the inflow of water from the water supply port 310 to the outer tank 120, and a water supply hose 330 that connects the water supply valve 320 and the outer tank 120. . The water supply port 310 is connected to, for example, a water tap. When the water supply valve 320 is opened, water is supplied to the outer tank 120.

  The washing machine 100 further includes a drainage system 400 for draining water out of the housing 110. The drainage system 400 includes a drainage pipe 410 extending from the connection duct 131 to the outside of the housing 110, and a drainage valve 420 attached to the drainage pipe 410. When the drain valve 420 is opened, the water in the outer tub 120 is drained out of the housing 110 through the connection duct 131 and the drain pipe 410. Similarly, the dehumidified water supplied to the heat exchanger 210 is drained out of the housing 110.

  The washing machine 100 further includes a cleaning pipe 132 that connects the water supply valve 320 and the drain pipe 410, and an optical sensor 133 that detects the turbidity of the water flowing through the drain pipe 410. The water supply valve 320 switches the path of water flowing from the water supply port 310 to the cleaning pipe 132 and cleans the drain pipe 410. As a result, the accuracy of water turbidity detection by the optical sensor 133 is maintained.

  The washing machine 100 includes a detergent container 500 that stores a liquid detergent supplied into the outer tub 120, a pumping device (not shown) that pumps the liquid detergent from the detergent container 500 into the outer tub 120, and the detergent container 500.

(Detergent container)
FIG. 2 is a schematic exploded perspective view of the detergent container 500. The detergent container 500 will be described with reference to FIG.

  As described above, the detergent container 500 that holds the liquid detergent in the casing 110 of the washing machine 100 includes the elongated and substantially rectangular box-shaped container portion 510. The container unit 510 includes a storage unit 515 that stores a liquid detergent, and a substantially cylindrical charging unit 520 that defines an opening 521 for charging the liquid detergent into the storage unit 515. The input part 520 protrudes upward from the accommodating part 515.

  The detergent container 500 further includes a lid 550 that closes the opening 521. The lid body 550 is attached to the input unit 520 in a rotational manner.

  FIG. 3 is a schematic enlarged perspective view of the container part 510 around the charging part 520. 4 is a schematic enlarged front view of the container portion 510 around the charging portion 520. FIG. The container 510 is described with reference to FIGS.

  The insertion portion 520 includes a substantially annular base end portion 523 connected to the housing portion 515 and a cylindrical portion 522 protruding upward from the base end portion 523. The cylindrical portion 522 includes an inner surface 524 that defines the opening 521 and a groove surface 525 opposite to the inner surface 524. A pair of substantially L-shaped groove portions 530 are formed on the groove surface 525.

  The cylindrical portion 522 further includes an end surface 526 between the upper edge of the inner surface 524 and the upper edge of the groove surface 525. An end surface 526 opposite to the base end portion 523 is pressed by the lid body 550.

  FIG. 5 is a schematic enlarged perspective view of the lid body 550. The lid body 550 is described with reference to FIGS. 2 and 5. FIG. 5 shows the internal structure of the lid 550.

  The lid body 550 formed in a substantially dish shape includes a substantially annular peripheral wall portion 551 and a substantially disc-shaped closing portion 552 for closing the opening portion 521. The peripheral wall portion 551 includes an outer surface 553 having a wavy contour and an inner surface 554 opposite to the outer surface 553. The user holding the outer surface 553 rotates the lid 550 on the input unit 520. The outer contour of the undulating lid body 550 facilitates the rotation of the lid body 550 by the user.

  The peripheral wall portion 551 further includes a protruding portion 555 that protrudes from the outer surface 553. The protrusion 555 includes a first protrusion 556 and a second protrusion 557 that protrudes in a direction opposite to the first protrusion 556. The protrusion 555 further facilitates the rotation of the lid 550 by the user.

  The blocking portion 552 includes a lower surface 558 facing the input portion 520 and an upper surface 559 opposite to the lower surface 558. The lid 550 further includes a substantially annular inner wall rib 560 that protrudes from the lower surface 558 into the opening 521. The inner wall rib 560 protrudes into the opening 521 of the input part 520. Between the inner wall rib 560 and the inner surface 554, the leading end of the input portion 520 enters. In the present embodiment, the inner wall rib 560 is exemplified as the inner wall portion.

  The peripheral wall portion 551 further includes a pair of substantially triangular columnar claw portions 561 protruding from the inner surface 554. The claw portion 561 meshes with the groove portion 530 of the insertion portion 520.

  FIG. 6 is a schematic longitudinal sectional view of the lid 550. The nail | claw part 561 is demonstrated using FIG.

  The claw portion 561 includes a facing surface 562 that faces the closing portion 552. The facing surface 562 is substantially parallel to the lower surface 558 of the closing portion 552.

  FIG. 7 is a schematic longitudinal sectional view of the charging unit 520. The groove portion 530 is described with reference to FIGS. 3, 6, and 7.

  The groove surface 525 includes a groove edge 531 that defines the contour of the groove portion 530. The groove edge 531 engages with the facing surface 562 of the claw portion 561.

  The groove edge 531 defines an insertion port 532 extending from the end surface 526 toward the base end portion 523 so that the claw portion 561 is inserted. The groove edge 531 further defines a moving section M extending in the circumferential direction of the insertion portion 520 from the insertion port 532. The claw portion 561 moves along the movement section M as the lid body 550 rotates. The moving section M extends along the inclined section M1 having the groove edge 531 inclined so that the pressure applied to the facing surface 562 increases with the rotation of the lid 550, and along the end face 526 (that is, substantially on the end face 526). And an end section M2 extending in parallel.

  In the inclined section M1, the groove edge 531 is inclined so as to gradually approach the base end portion 523. Therefore, the width W of the groove portion 530 gradually decreases toward the end section M2.

  FIG. 8 is a schematic cross-sectional view of the input portion 520 to which the lid body 550 is attached. The groove part 530 is further demonstrated using FIG.3 and FIG.8.

  The groove surface 525 further includes a raised portion 533 raised in the end section M2. Since the claw portion 561 that moves along the end section M2 contacts the raised portion 533, the user can perceive that the lid body 550 is properly attached to the insertion portion 520. The raised portion 533 is adjacent to the claw portion 561 that has reached the end of the moving section M. Therefore, the claw portion 561 is unlikely to return to the inclined section M1 from the end of the moving section M.

  FIG. 9 is a schematic longitudinal sectional view of the charging unit 520 to which the lid body 550 is attached. The detergent container 500 is further described with reference to FIGS. 2, 3 and 9.

  The detergent container 500 further includes an O-ring 570 that is used as a packing element that is compressed between the end surface 526 of the charging portion 520 and the closing portion 552. The O-ring 570 is held between the inner wall rib 560 and the inner surface 554. Since the O-ring 570 is gradually compressed while the claw portion 561 toward the end of the moving section M passes through the inclined section M1, the pressure applied to the facing surface 562 gradually increases as the lid body 550 rotates. . Thereafter, when the claw portion 561 reaches the end section M2, the user perceives that the force against the rotation of the lid 550 becomes constant. Thus, the user can perceive the transition from the slope section M1 to the end section M2. Thereafter, when the claw portion 561 comes into contact with the raised portion 533, the user can perceive that the attachment of the lid 550 is completed.

  10 and 11 are schematic cross-sectional views of the lid body 550 and the insertion portion 520 that sandwich the packing member. FIG. 10 shows the packing member when the internal pressure of the container 510 increases. FIG. 11 shows the packing member when the internal pressure of the container 510 is lowered. The other sealing method between the cover body 550 and the insertion part 520 is demonstrated using FIG.10 and FIG.11.

  An annular packing member 580 having a substantially V-shaped cross section may be used as the packing element. The packing member 580 includes a first end edge 581 along the inner edge of the end surface 526 and a second end edge 582 adjacent to the first end edge 581. The second end edge 582 exists between the first end edge 581 and the closing portion 552.

  The packing member 580 includes a flat upper surface 588 that contacts the closing portion 552 and a flat lower surface 589 that contacts the end surface 526. The upper surface 588 is in pressure contact with the closing portion 552 and exhibits a sealing function. The lower surface 589 is pressed against the end surface 526 and exhibits a sealing function. In the present embodiment, the upper surface 588 is exemplified as the first surface. The lower surface 589 is exemplified as the second surface.

  As shown in FIG. 10, the packing member 580 is deformed by an increase in the internal pressure of the container portion 510, and the second end edge 582 is separated from the first end edge 581. As a result, the sealing performance between the lid body 550 and the charging section 520 increases while the internal pressure of the container section 510 is increasing. On the other hand, when the internal pressure of the container portion 510 is low, the second end edge 582 is adjacent to the first end edge 581.

  While the liquid detergent is discharged from the detergent container 500, the internal pressure of the container 510 increases. As described above, since the sealing performance between the lid 550 and the charging unit 520 is improved during this period, the liquid detergent is less likely to leak from between the lid 550 and the charging unit 520.

  While the user attaches the lid body 550 to the input part 520, the internal pressure of the container part 510 is relatively small. Accordingly, during this time, the second edge 582 is adjacent to the first edge 581. As a result, the drag force that the packing member 580 gives to the rotation operation of the user's lid 550 is relatively small. Thus, the user can attach the lid 550 to the input portion 520 relatively easily.

  As described above, an L-shaped groove 530 is formed in the insertion portion 520 in accordance with the principle of the present embodiment. The lid body 550 includes a claw portion 561 that meshes with the groove portion 530. As a result, the user can appropriately attach the lid 550 to the input unit 520.

  Another method for preventing the lid from being attached obliquely to the inlet is to form a double thread on the outer peripheral surface of the inlet and the inner peripheral surface of the lid. Such a method can also prompt the user to attach the lid appropriately.

  INDUSTRIAL APPLICATION This invention is utilized suitably for the washing machine incorporating the container which accommodates a detergent, and the container which accommodates a detergent.
