Description

Technical Field

[0001] Embodiments of the present invention relate to washing machines.

Background Art

[0002] In recent years, there has been a demand to wash more laundry at once, and in order to increase the capacity of the laundry, the internal volume of the rotating tub has been increased. On the other hand, the installation space for washing machines in living spaces is limited, and it is difficult to increase the size of the washing machine itself in accordance with the increase in the size of the rotating tub. Therefore, in order to increase the internal volume of the rotating tub without increasing the size of the washing machine itself, it is necessary to reduce the size of the internal structure of the washing machine and secure space for the rotating tub.

[0003] By the way, conventionally, a structure has been adopted in which an injection port is provided in a circulation path for circulating water in a water tank, and the water that has passed through the circulation path is injected into the water tank from the injection port. On the other hand, there is a desire to clean detergents and the like attached to the inside of a door that opens and closes an opening for loading and unloading laundry, and to keep the inside of the door clean. In this case, if the structure for injecting the water that has passed through the circulation path into the water tank and the structure for cleaning the inside of the door are arranged independently, there is a risk of hindering the miniaturization of the internal structure of the washing machine.

Embodiments for Carrying Out the Invention

[0008] Hereinafter, a plurality of embodiments of the present invention will be described with reference to the drawings. In each embodiment, substantially the same elements are denoted by the same reference numerals, and the description thereof will be omitted. Further, in the following embodiments, the terms "first", "second", etc. attached to components are for simply distinguishing similar components, and do not mean superiority or inferiority between components or time elements.

[0009] (First Embodiment) The washing machine 10 shown in FIG. 1 is a drum-type washing machine of a horizontal axis type in which the rotation axis of the rotary tub 13 is horizontal or an inclined axis type in which it slopes downward toward the rear. Note that the washing machine 10 may or may not have a drying function. As shown in FIG. 1, the washing machine 10 includes an outer case 11, a water tub 12, a rotary tub 13, a water tub cover 14, a water passage forming member 15, a door 16, and a motor 17. In FIG. 1, the installation surface side of the washing machine 10, that is, the vertically lower side, is defined as the lower side of the washing machine 10, and the side opposite to the installation surface, that is, the vertically upper side, is defined as the upper side of the washing machine 10. The front side of the washing machine 10 as viewed from the user, that is, the left side of the paper surface in FIG. 1, is defined as the front side of the washing machine 10, and the side opposite to the user, that is, the back side of the washing machine 10, is defined as the rear side of the washing machine 10. Further, when the rotary tub 13 is rotated, the traveling direction of the outer peripheral surface of the rotary tub 13 is referred to as the circumferential direction. Also, the direction orthogonal to the rotation axis of the rotary tub 13 is referred to as the radial direction.

[0010] The outer case 11 is formed in a substantially rectangular hollow box shape by, for example, a stainless steel plate or the like. The outer case 11 constitutes the outer shell of the washing machine 10. The outer case 11 has an opening 111 in the front side portion that communicates the inside and outside of the outer case 11. Both the water tub 12 and the rotary tub 13 are formed in a so-called bottomed cylindrical shape in which one side in the axial direction, that is, the front side, is open and the other side, that is, the rear side, has a bottom. The water tub 12 is provided inside the outer case 11 and is elastically supported by a suspension (not shown). The water tub 12 has a drain port 121 as shown in FIG. 1. The drain port 121 is provided near the rear side bottom of the water tub 12 and communicates the inside and outside of the water tub 12.

[0011] The rotating tub 13 is rotatably disposed within the water tub 12. The rotating tub 13 is rotationally driven by a motor 17. The rotating tub 13 has a number of holes 131. The holes 131 are formed over substantially the entire circumferential surface of the rotating tub 13 and function as water passage holes through which water enters and exits, for example, during the washing process, rinsing process, and dehydration process. Further, a plurality of baffles (not shown) are provided on the inner circumferential surface of the rotating tub 13. The baffles have the function of stirring and lifting up the laundry accommodated within the rotating tub 13.

[0012] The water tub cover 14 is made of, for example, synthetic resin and is provided on the front side (i.e., the opening side) of the water tub 12. The water tub cover 14 has a water tub opening 141, a supply port 142, and a wall portion 20. The water tub opening 141 is provided at the center of the water tub cover 14. The water tub opening 141 is formed to penetrate the water tub cover 14 in the axial direction, for example, in a circular shape, and communicates the inside and outside of the water tub 12. As shown in FIGS. 1 and 2, the supply port 142 is provided, for example, at the lower part of the water tub cover 14 and is offset to one side, in this case, slightly to the left side, with respect to the center in the left-right direction of the water tub cover 14. The supply port 142 is the portion that connects the water tub cover 14 and the circulation hose 44.

[0013] As shown in FIGS. 1 and 3 etc., the wall portion 20 is formed to project from the rear surface 143 of the water tub cover 14 (i.e., the surface on the water tub 12 side). The wall portion 20 can be configured to have a plurality of wall portions with different shapes. In this case, for example, a first wall portion 21 and a second wall portion 22. As shown in FIG. 3, the first wall portion 21 is formed along the circumferential direction and radial direction of the water tub cover 14 from the lower part to the upper part of the water tub cover 14. As shown in FIGS. 3 and 4, the second wall portion 22 is formed to extend along the radial direction of the water tub cover 14 above the water tub opening 141. In this case, the second wall portion 22 is configured by a plurality of stepped shapes in a front view or a rear view. The second wall portion 22 is not limited to a plurality of stepped shapes and may be configured linearly. The second wall portion 22 is for partitioning the region defined by the rear surface 143 of the water tub cover 14 and the first wall portion 21. Note that the wall portion 20 may be integrally formed with the water tub cover 14 or may be a separate body.

[0014] The water channel forming member 15 is made of, for example, synthetic resin and covers a part of the rear surface 143 of the water tank cover 14. In this case, the water channel forming member 15 is configured to cover the range including the wall portion 20. The water channel forming member 15 is attached to the water tank cover 14 by, for example, snap fit, screws, etc. The water channel forming member 15 may be fixed to the water tank cover 14 by welding, an adhesive, etc. At this time, as shown in FIG. 3 etc., a space S is formed between the rear surface 143 of the water tank cover 14, the wall portion 20, and the water channel forming member 15. This space S has a size that allows a liquid such as water to pass through. The second wall portion 22 functions as a wall that closes the space S. That is, the space S is divided into a plurality of spaces with the second wall portion 22 as a boundary.

[0015] The door 16 is provided on the front side of the outer box 11 and opens and closes the opening 111. The door 16 has a window portion 161. The window portion 161 is made of, for example, a transparent or translucent member. For this reason, the user can visually recognize the inside of the rotating tank 13 from the outside through the window portion 161. As shown in FIG. 1, the window portion 161 is configured to bulge so as to enter the inside of the water tank 12. And the end portion of the window portion 161 on the water tank 12 side is arranged at a position overlapping the water tank cover 14.

[0016] The motor 17 is provided outside the bottom of the water tank 12. Although not shown in detail, the motor 17 is composed of, for example, a brushless direct drive motor whose rotation speed can be changed. The motor 17 is connected to the rotating tank 13 and has a function of relatively rotationally driving the rotating tank 13 with respect to the water tank 12. In this case, the shaft portion 171 of the motor 17, the central axis of the water tank 12, and the rotation axis of the rotating tank 13 overlap each other.

[0017] In addition, the washing machine 10 includes a water injection mechanism 30, a circulation drainage device 40, and a cleaning device 50. The water injection mechanism 30 has a function of supplying water from an external water source such as a water supply to the water tank 12. As shown in FIG. 1, the water injection mechanism 30 includes a water supply valve 31, a water injection case 32, and a water injection hose 33. The water supply valve 31 is configured to be electromagnetically openable and closable. The water supply valve 31 is connected to an external water source such as a faucet of a water supply (not shown). Then, the water supply valve 31 opens and closes a path leading from the external water source to the inside of the water tank 12 via the water injection case 32.

[0018] The water injection case 32 is configured to be able to store a laundry treatment agent therein. The laundry treatment agent includes, for example, detergents such as powder detergents and liquid detergents, and finishing agents such as softeners and fabric conditioners. The water injection hose 33 is, for example, a flexible hose and is configured in a cylindrical shape. One end of the water injection hose 33 is connected to the water injection case 32, and the other end is connected to the water tank 12. The water injection hose 33 has a function of injecting the water that has flowed into the water injection case 32 from the external water source into the water tank 12. When water flows into the water injection case 32 with the laundry treatment agent stored therein, the laundry treatment agent in the water injection case 32 mixes with the water flowing in the water injection case 32 and then flows through the water injection hose 33 into the water tank 12.

[0019] The circulation drainage device 40 has a function of circulating the water in the water tank 12 and a function of draining the water in the water tank 12 outside the washing machine 10. As shown in FIG. 1, the circulation drainage device 40 includes a connection hose 41, a filter section 42, a circulation pump 43, a circulation hose 44, a drain valve 45, and a drain hose 46. The connection hose 41 is, for example, a flexible hose. One end of the connection hose 41 is connected to the drain port 121, and the other end is connected to the filter section 42. The filter section 42 is provided between the drain port 121 and the drain valve 45. The filter section 42 has a mesh filter (not shown) inside, and the filter collects lint and dust contained in the water passing through the filter section 42.

[0020] The circulation pump 43 is for pumping up the water in the water tank 12 through the drain port 121 and the connection hose 41 and then pouring it back into the water tank 12. The circulation hose 44 is composed of, for example, a flexible hose. One end of the circulation hose 44 is connected to the circulation pump 43, and the other end is connected to the supply port 142. That is, the circulation hose 44 connects the circulation pump 43 and the water tank cover 14. The drain valve 45 is configured to be electromagnetically openable and closable. One end of the drain hose 46 is connected to the drain valve 45, and the other end is drawn out outside the washing machine 10.

[0021] When the drain valve 45 is opened with water stored in the water tank 12, the water stored in the water tank 12 is discharged outside the washing machine 10 through the drain hose 46. That is, the drain valve 45 opens and closes the drain path for draining the water stored in the water tank 12 to the outside. On the other hand, when the circulation pump 43 is driven with the drain path closed by the drain valve 45, the circulation pump 43 pumps up the water in the water tank 12 through the drain port 121 and the connection hose 41 and supplies the water stored in the water tank 12 to the supply port 142 via the circulation hose 44.

[0022] As shown in FIG. 1, the cleaning device 50 can be configured to have, for example, an on-off valve 51, a cleaning water hose 52, and a nozzle portion 53. The on-off valve 51 is configured to be electromagnetically openable and closable and is provided on the downstream side of the water supply valve 31. The on-off valve 51 opens and closes the path for the water supplied from an external water source to the nozzle portion 53. One end of the cleaning water hose 52 is connected to the on-off valve 51, and the other end is connected to the nozzle portion 53.

[0023] As shown in FIGS. 1 and 2, the nozzle portion 53 is provided, for example, at the upper part of the water tank cover 14, closer to one side with respect to the center in the left-right direction of the water tank cover 14. In this case, it is provided on the right side. That is, the nozzle portion 53 and the supply port 142 are provided in different directions in the left-right direction of the water tank cover 14. The nozzle portion 53 is the part that connects the cleaning water hose 52 and the water tank cover 14.

[0024] The nozzle portion 53 is formed, for example, in a cylindrical shape extending in a substantially vertical direction, and is provided so as to penetrate the water tank cover 14 and the first wall portion 21 in the thickness direction. And the nozzle portion 53 communicates with the space S formed between the water tank cover 14 and the water channel forming member 15, and is configured to be able to introduce the water supplied from an external water source into the space S. Note that the nozzle portion 53 is not limited to a configuration extending in a substantially vertical direction, and may be inclined.

[0025] Next, a configuration example of the water tank cover 14 and its peripheral portion will be described. In the present embodiment, as shown in FIGS. 3 to 7, the water tank cover 14 has a circulation discharge portion 61 and a door washing discharge portion 62. The circulation discharge portion 61 is provided at the upper part of the water tank opening 141, that is, at two positions, one on each of the left and right sides with respect to the center of the water tank cover 14 in the left-right direction, that is, a total of two positions. The circulation discharge portion 61 is provided on the rear side of the water tank cover 14, that is, on the water tank 12 side.

[0026] As shown in FIG. 5, the circulation discharge portion 61 is formed to penetrate the bottom surface 144 of the water tank cover 14 in the thickness direction, and is formed, for example, in a rectangular shape. The circulation discharge portion 61 is for directly supplying the water that has flowed through the space between the water tank cover 14 and the water channel forming member 15 into the water tank 12 through the supply port 142. The term "directly" means that the water discharged from the circulation discharge portion 61 is supplied into the water tank 12 without flowing through other members such as the window portion 161.

[0027] As shown in FIG. 2 and the like, the ejection part 62 for door washing is provided, for example, above the water tank opening 141 and closer to one side with respect to the lateral center of the water tank cover 14. In this case, it is provided on the rightward side part. As shown in FIG. 5, the ejection part 62 for door washing is provided at a position axially shifted from the circulation ejection part 61 in the water tank 12 and at a position not overlapping each other in the lateral direction of the water tank 12. In this case, the ejection part 62 for door washing is provided on the rightward side part in the lateral direction of the water tank 12 rather than the circulation ejection part 61. The ejection part 62 for door washing is formed by penetrating the first wall part 21 and the bottom surface 144 of the water tank cover 14 in the thickness direction, and is formed in a cylindrical shape extending, for example, in a substantially vertical direction. And, as shown in FIG. 5, the opening area of the ejection part 62 for door washing is smaller than the opening area of the circulation ejection part 61. Note that the ejection part 62 for door washing is not limited to a configuration extending in a substantially vertical direction and may be inclined.

[0028] As shown in FIGS. 5 and 7, the ejection part 62 for door washing is provided on the front side of the water tank cover 14, that is, on the opening part 111 side, and is arranged at a position overlapping in the horizontal direction with the window part 161, that is, at a position overlapping in plan view. In this case, as shown in FIG. 7, the ejection part 62 for door washing is located on the front side of the water tank 12 side end of the window part 161, that is, on the opening part 111 side. The ejection part 62 for door washing is for flowing the water that has flowed through the space S between the water tank cover 14 and the water channel forming member 15 via the cleaning device 50 from an external water source to the window part 161 of the door 16. In this case, the ejection part 62 for door washing is open toward the window part 161. Therefore, the ejection part 62 for door washing can eject water toward the window part 161.

[0029] Further, as shown in FIG. 1, the washing machine 10 can be configured to include, as a water supply path, for example, a water injection path 71, a circulation path 72, and a door washing path 73. The water injection path 71 is a path that reaches the water tank 12 through, for example, the water injection mechanism 30. The circulation path 72 is a path that reaches the water tank 12 through, for example, the connection hose 41, the filter unit 42, the circulation pump 43, the circulation hose 44, the supply port 142, the space S, and the circulation discharge unit 61. That is, the circulation path 72 is a path for circulating the water in the water tank 12. When the circulation pump 43 is driven with the drain valve 45 closed, the water in the water tank 12 is pumped up by the circulation pump 43 and then re-injected into the water tank 12 from the circulation discharge unit 61. In this case, the circulation path 72 constitutes a path for flowing water in the direction indicated by the black arrow A in FIG. 6.

[0030] The door washing path 73 is a path that reaches the window portion 161 through the water supply valve 31, the on-off valve 51, the cleaning device 50, the space S, and the door washing discharge unit 62. That is, the door washing path 73 is a path for flowing the water supplied from an external water source to the window portion 161 to clean the window portion 161. When the water supply valve 31 and the on-off valve 51 are opened, the water supplied from the external water source flows from the door washing discharge unit 62 to the window portion 161 through the washing water hose 52 and then is supplied into the water tank 12. In this case, the door washing path 73 constitutes a path for flowing water in the direction indicated by the black arrow B in FIG. 7.

[0031] The door washing path 73 is a path for the water supplied from an external water source to reach the window portion 161 without passing through the water tank 12 or the water injection case 32. Therefore, water that does not contain dirt removed from the detergent component or the laundry can be supplied to the window portion 161. For this reason, for example, it is possible to efficiently clean the window portion 161 while preventing the reattachment of the detergent component or dirt to the window portion 161.

[0032] In the case of this embodiment, the circulation path 72 and the door washing path 73 are configured to include the space S as a common configuration. As described above, the space S is formed between the rear surface 143 of the water tank cover 14, the wall portion 20, and the water channel forming member 15. That is, the door washing path 73 is configured using the same members as those constituting a part of the circulation path 72, in this case, the water tank cover 14 and the water channel forming member 15. In other words, the water channel forming member 15 forms a part of the circulation path 72 and the door washing path 73 between the water tank cover 14. In this way, by configuring the circulation path 72 and the door washing path 73 using the same members, the common use of members can be achieved, and the internal structure of the washing machine 10 can be optimized.

[0033] On the other hand, as shown in FIG. 3, the space S is partitioned by the second wall portion 22. Therefore, the water flowing through the circulation path 72 and the door washing path 73 is divided by the second wall portion 22 and does not cross each other. Thereby, it is possible to suppress the water flowing through each path 72, 73 from interfering with each other and efficiently prevent the smooth water flow from being hindered.

[0034] According to the embodiment described above, the washing machine 10 includes an outer case 11, a water tank 12, a door 16, a circulation path 72, and a door washing path 73. The outer case 11 has an opening 111 that communicates the inside and the outside. The water tank 12 is formed in a bottomed cylindrical shape, provided inside the outer case 11, and connected to the opening 111. The door 16 is provided on the outer case 11 and opens and closes the opening 111. The circulation path 72 circulates the water in the water tank 12. And the door washing path 73 is configured using the same members as those constituting a part of the circulation path 72, and water is made to flow through the door 16 to wash the door 16.

[0035] According to this, by using a common member for the members constituting the circulation path 72 and the door washing path 73, compared with the case where the circulation path 72 and the door washing path 73 are separately configured with separate parts, the structure inside the washing machine 10 can be optimized, that is, the structure inside the washing machine 10 can be miniaturized. And the structure for draining water to the door 16 can be miniaturized. Thereby, space saving inside the washing machine 10 can be achieved, and as a result, the enlargement of the washing machine 10 can be suppressed. Also, since there is no need to provide dedicated parts for constituting each path 72, 73, the number of parts can be reduced, and the assembly workability can be improved.

[0036] Further, the washing machine 10 further includes a water tank cover 14 and a water passage forming member 15. The water tank cover 14 is provided on the opening 111 side of the water tank 12. The water passage forming member 15 covers a part of the surface of the water tank cover 4 on the water tank 12 side, and forms a part of the circulation path 72 and the door washing path 73 between the water tank cover 14.

[0037] According to this, the water tank cover 14 can be effectively used as a part constituting the circulation path 72 and the door washing path 73. Thereby, the number of parts can be reduced, and the decrease in the assembly workability of the washing machine 10 can be suppressed as much as possible.

[0038] The water tank cover 14 has a wall portion 20. The wall portion 20 is formed to protrude from the water tank cover 14 toward the water passage forming member 15 side, and is covered by the water passage forming member 15 to constitute the walls of the circulation path 72 and the door washing path 73. According to this, by covering the wall portion 20 provided on the water tank cover 14 with the water passage forming member 15, the circulation path 72 and the door washing path 73 can be constituted with a simple structure.

[0039] (Second Embodiment) The second embodiment will be described with reference to FIG. 8. In the second embodiment shown in FIG. 8, the configurations of the water tank cover 14 and the water channel forming member 15 are different from those of the first embodiment. Specifically, in the first embodiment, the wall portion 20 is provided on the rear surface 143 of the water tank cover 14. On the other hand, in this embodiment, the wall portion is provided on the front surface side of the water channel forming member 15, that is, the surface on the water tank cover 14 side, rather than on the water tank cover 14. That is, in this embodiment, instead of the wall portion 20 of the first embodiment, the water channel forming member 15 protrudes from the water channel forming member 15 toward the water tank cover 14 side and has a wall portion 80 that is covered by the water tank cover 14 and constitutes the walls of the circulation path 72 and the door washing path 73.

[0040] In this case, the wall portion 80 has a first wall portion 81 and a second wall portion 82. The first wall portion 81 and the second wall portion 82 can be configured to have the same shape as the first wall portion 21 and the second wall portion 22, respectively. Therefore, as shown in FIG. 8, by covering the wall portion 80 of the water channel forming member 15 with the rear surface 143 of the water tank cover 14, a space S is formed, and the circulation path 72 and the door washing path 73 can be configured. Note that the wall portion 80 may be formed integrally with the water channel forming member 15 or may be a separate body.

[0041] According to such a second embodiment, by covering the wall portion 80 provided on the water channel forming member 15 with the water tank cover 14, the circulation path 72 and the door washing path 73 can be configured with a simple structure. In addition, since the water tank cover 14 is larger and has a more complex structure than the water channel forming member 15, for example, when trying to change the shape of the wall portion 20, the work burden is not small. Therefore, by providing the wall portion 80 on the water channel forming member 15 side, it is possible to easily and flexibly respond to changes in the shape of the wall portion 80 and thus design changes in the circulation path 72 and the door washing path 73.

[0042] (Third Embodiment) Next, the third embodiment will be described with reference to FIGS. 9 and 10. In the third embodiment shown in FIGS. 9 and 10, the water source used for door washing is different from those in the above embodiments. In the case of this embodiment, the washing machine 10 does not include the cleaning device 50 and the circulation discharge part 61. However, as shown in FIG. 10, a water passage part 221 is formed in the second wall part 22. The water passage part 22 can be configured in a circular shape, for example, penetrating the second wall part 22 in the thickness direction. The water passage part 22 is for guiding a part of the water flowing through the circulation path 72 to the door washing path 73. That is, in the case of this embodiment, the door washing path 73 can be configured as a part of the circulation path 72. And the door washing path 73 is a path for flowing a part of the water flowing through the circulation path 72 to the window part 161 to wash the window part 161. The number of the water passage parts 22 may be one or a plurality. Also, the shape of the water passage part 22 is not limited to a circular shape, and may be a rectangular shape or an elliptical shape.

[0043] Even with this configuration, by using common members for the members constituting the circulation path 72 and the door washing path 73, compared with the case where the circulation path 72 and the door washing path 73 are separately configured with separate parts, the structure inside the washing machine 10 can be optimized, that is, the structure inside the washing machine 10 can be miniaturized. Furthermore, by changing the shape of the water passage part 22, it is possible to easily adjust the amount of water flowing into the door washing path 73 per unit time in the circulation path 72, so that the design change of the door washing path 73 can be flexibly responded to.

[0044] Note that the above embodiments can be combined with each other. Also, only the characteristic parts of two or more embodiments can be extracted and combined. The above embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the gist of the invention.
