Device and washing machine

Abstract

A device and a washing machine are disclosed. The device includes: a main body mounted on an inner circumferential face of the washing tank; an intake port provided at a lower end portion of the main body; a waterway; and an exhaust port provided on a surface of an upper end portion of the main body. Water is guided through the waterway so as to be exhausted from the exhaust port and splashed onto laundry in the washing tank. The exhaust port is relatively long in a circumferential direction Y of the inner circumferential face, a top-to-bottom width of the exhaust port in the middle is narrower than that at both ends in the circumferential direction Y, and a groove on the surface of the main body is adjacently arranged on two outer sides of the exhaust port in the circumferential direction Y.

1 . A device for use in a vertical washing machine, the vertical washing machine having a cylindrical washing tank with a bottom and is formed with an access port for laundry at an upper end and is provided with a bottom wall at a lower end; the device comprises:
 a main body, having a back face which is opposite to an inner circumferential face of the washing tank and a surface which is located on an opposite side of the back face and faces a central axis side of the washing tank; wherein the main body is mounted on the inner circumferential face of the washing tank in a posture along the up-down direction;   an intake port, which is provided at a lower end portion of the main body for introducing water in the washing tank from a bottom wall side;   a waterway, which is provided in the main body for guiding the water introduced by the intake port upwardly; and   an exhaust port, which is provided on a surface of an upper end portion of the main body for exhausting the water guided by the waterway and splashing the water onto laundry in the washing tank,   wherein the exhaust port is relatively long in a circumferential direction of the inner circumferential face of the washing tank,   a top-to-bottom width of the exhaust port in the middle of the circumferential direction is narrower than that at both ends in the circumferential direction, and   a groove on the surface of the main body is adjacently arranged on two outer sides of the exhaust port in the circumferential direction.   
     
     
         2 . The device according to  claim 1 , wherein
 the device is mounted on the inner circumferential face of the washing tank in a state that a plurality of devices are gathered together and are arranged in the circumferential direction, and   each of the devices comprises a guiding member, which is arranged on the surface of the main body in such a way that an upper end of the exhaust port is bordered, and guides the water exhausted from the exhaust port in an obliquely downward direction relative to the horizontal direction.   
     
     
         3 . The device according to  claim 1 , wherein
 the device is mounted on the inner circumferential face of the washing tank in a state that a plurality of devices are gathered together and arranged in the circumferential direction, and   each of the devices comprises a blocking member, which blocks an end portion on a same side in the circumferential direction in the exhaust port.   
     
     
         4 . A washing machine, comprising a device for use in a vertical washing machine, the vertical washing machine having a cylindrical washing tank with a bottom and is formed with an access port for laundry at an upper end and is provided with a bottom wall at a lower end; the device comprises:
 a main body, having a back face which is opposite to an inner circumferential face of the washing tank and a surface which is located on an opposite side of the back face and faces a central axis side of the washing tank; wherein the main body is mounted on the inner circumferential face of the washing tank in a posture along the up-down direction;   an intake port, which is provided at a lower end portion of the main body for introducing water in the washing tank from a bottom wall side;   a waterway, which is provided in the main body for guiding the water introduced by the intake port upwardly; and   an exhaust port, which is provided on a surface of an upper end portion of the main body for exhausting the water guided by the waterway and splashing the water onto laundry in the washing tank,   wherein the exhaust port is relatively long in a circumferential direction of the inner circumferential face of the washing tank,   a top-to-bottom width of the exhaust port in the middle of the circumferential direction is narrower than that at both ends in the circumferential direction, and   a groove on the surface of the main body is adjacently arranged on two outer sides of the exhaust port in the circumferential direction.   
     
     
         5 . The device according to  claim 2 , wherein
 the device is mounted on the inner circumferential face of the washing tank in a state that a plurality of devices are gathered together and arranged in the circumferential direction, and   each of the devices comprises a blocking member, which blocks an end portion on a same side in the circumferential direction in the exhaust port.   
     
     
         6 . The washing machine according to  claim 4 , wherein
 the device is mounted on the inner circumferential face of the washing tank in a state that a plurality of devices are gathered together and are arranged in the circumferential direction, and   each of the devices comprises a guiding member, which is arranged on the surface of the main body in such a way that an upper end of the exhaust port is bordered, and guides the water exhausted from the exhaust port in an obliquely downward direction relative to the horizontal direction.   
     
     
         7 . The washing machine according to  claim 4 , wherein
 the device is mounted on the inner circumferential face of the washing tank in a state that a plurality of devices are gathered together and arranged in the circumferential direction, and   each of the devices comprises a blocking member, which blocks an end portion on a same side in the circumferential direction in the exhaust port.
