Definitions

  • the present invention relates to washing machines, and more particularly to a washing machine that can prevent damage of a tub.
  • a washing machine includes a tub within a cabinet, which defines an appearance of the washing machine.
  • the tub is supported by a damper connected to a lower side of the cabinet and has a drum rotatably disposed therein.
  • the drum is formed at lower and lateral sides thereof with a plurality of holes through which wash water in the tub can freely flow between the drum and the tub to remove dirt from laundry.
  • the washing machine includes a heater located near the bottom of the tub to heat wash water. Further, the washing machine is provided with a controller which controls operation of the heater by turning the heater on or off based on the temperature of wash water detected by a temperature sensor.
  • the heater can be dropped to the bottom of the tub. As a result, the heater damages the tub and electric wires on the bottom of the tub, thereby causing malfunction of the washing machine and fire.
  • wash water is heated by the heater, the operation of the heater is limited by the temperature to which the wash water is heated.
  • heated wash water is circulated only by convection, so that the temperature of the wash water received in the tub cannot be accurately detected. Since such circulation of the wash water causes the wash water around the heater to be overheated, the heater is repetitiously turned-on and off to heat the wash water to a preset temperature.
  • the present invention is conceived to solve the problems of the conventional washing machine as described above, and an aspect of the present invention is to provide a washing machine that can prevent damage of a tub even when a heater is separated from the tub.
  • Another aspect of the present invention is to provide a washing machine that can forcibly circulate heated wash water.
  • a washing machine includes: a tub receiving wash water; a heater heating the wash water; and a heater cover surrounding the heater.
  • the heater cover may be formed with an insertion hole into which the heater is inserted.
  • the heater cover may be formed to surround a lower side of the heater.
  • the heater cover may be formed to surround an entirety of the heater at a distance from the heater.
  • the heater cover may be formed with a penetration hole which is in communication with the tub.
  • the tub may have a protrusion formed outwardly on a lower side thereof to receive the heater cover inside the protrusion.
  • the washing machine may further include a pump which is in communication with the protrusion.
  • the washing machine may further include a circulation pipe which is in communication with the pump and an upper side of the tub, and a discharge pipe which is in communication with the pump and an outside of the washing machine.
  • the washing machine may further include a selective blocking part selectively blocking the circulation pipe and the discharge pipe.
  • the heater cover may be made of a thermally resistant material.
  • FIG. 1 is a view of a washing machine according to an embodiment of the present invention
  • FIG. 2 is a perspective view of a heater cover of the washing machine according to the embodiment of the present invention.
  • FIG. 3 is a view of a selective blocking part of the washing machine according to the embodiment of the present invention, in which the selective blocking part blocks a circulation pipe of the washing machine;
  • FIG. 4 is a view of the selective blocking part of the washing machine according to the embodiment of the present invention, in which the selective blocking part blocks a discharge pipe of the washing machine.
  • FIG. 1 is a view of a washing machine according to an embodiment of the invention
  • FIG. 2 is a perspective view of a heater cover of the washing machine according to the embodiment
  • FIG. 3 is a view of a selective blocking part of the washing machine according to the embodiment, in which the selective blocking part blocks a circulation pipe of the washing machine
  • FIG. 4 is a view of the selective blocking part of the washing machine according to the embodiment, in which the selective blocking part blocks a discharge pipe.
  • the washing machine includes a tub 110 receiving wash water, a drum 111 within the tub 110 , a heater 130 heating the wash water, a heater cover 120 surrounding the heater 130 , a water supply part W supplying the wash water into the tub 110 , and a controller (not shown) controlling operation of the washing machine.
  • a damper D is provided between a cabinet C and the tub 110 to absorb vibration or impact caused by rotation of the drum 111 or by laundry falling within the drum 111 .
  • the tub 110 has a protrusion 115 formed on a lower side of the tub 110 . That is, the protrusion 115 is formed on an outer lower surface of the tub 110 .
  • the heater cover 120 is located within the protrusion 115 .
  • the heater cover 120 is configured to surround the heater 130 while preventing the heater 130 from contacting the tub 110 .
  • the heater cover 120 may be formed to surround upper and lower sides of the heater 130 , or to surround the entirety of the heater at a distance from the heater 130 , as shown in FIG. 2 . Since the heater 130 is located within the heater cover 120 , the heater cover 120 may be formed of a thermally resistant material. In this embodiment, the heater cover 120 is made from a SUS material which is resistant to moisture and heat.
  • the heater cover 120 is formed with a penetration hole 121 which is in communication with the tub 110 . Wash water flows into the heater cover 120 through the penetration hole 121 or flows from the heater cover 120 through the penetration hole 121 after being heated. Further, the heater cover 120 is formed with an insertion hole 123 into which the heater 130 is inserted.
  • the heater 130 is secured to the tub 110 by a heater bracket (not shown). Such a securing manner is apparent to those skilled in the art and a detailed description thereof will be omitted herein.
  • the heater 130 is inserted into the insertion hole 123 formed in the heater cover 120 and is disposed within the heater cover 120 to heat wash water flowing into the heater cover 120 through the penetration hole 121 .
  • the pump 140 forces wash water received in the tub 110 to move.
  • the pump 140 is in communication with the protrusion 115 through a movement pipe 141 . Further, the pump 140 is in communication with an upper side of the tub 110 through a circulation pipe 143 and is in communication with the outside of the washing machine through a discharge pipe 145 . Wash water introduced into the pump 140 is selectively moved to the circulation pipe 143 or the discharge pipe 145 by a selective blocking part 150 .
  • Wash water heated during a washing cycle is moved to the tub 110 through the movement pipe 141 , pump 140 and circulation pipe 143 by operation of the pump 140 . Accordingly, the wash water heated by the heater 130 is circulated not only by convection, but is also forcibly circulated by the pump 140 .
  • This circulation manner allows the heated wash water to be rapidly mixed with non-heated wash water, thereby preventing the wash water from being overheated while reducing heating time. Further, this circulation manner can prevent the controller from turning-off the heater 130 by preventing the wash water near the heater 130 from being rapidly overheated, and can reduce an amount of detergent deposits by helping to mix a detergent with the wash water through forcible circulation of the wash water.
  • the selective blocking part 150 selectively blocks the circulation pipe 143 and the discharge pipe 145 .
  • the selective blocking part 150 includes a blocking member 151 and an arm 153 .
  • the blocking member 151 selectively blocks the circulation pipe 143 and the discharge pipe 145 to allow wash water to be introduced into the tub 110 through the circulation pipe 143 or to be discharged outside through the discharge pipe 145 .
  • the arm 153 is mounted on the blocking member 151 , and selectively opens or closes the circulation pipe 143 or the discharge pipe 145 in association with a left or right movement of the blocking member 151 .
  • the selective blocking part 150 is a hydraulic cylinder.
  • the selective blocking part 150 can be modified in various forms such as solenoid valves and the like.
  • the washing machine may prevent fire and damage of a tub even when a heater is separated from the tub.
  • the washing machine heats wash water while circulating the wash water, thereby preventing the wash water from being rapidly overheated.
  • the washing machine heats wash water while circulating the wash water, thereby reducing heating time.
  • the washing machine heats wash water while circulating the wash water, so that the wash water around the heater can be prevented from being rapidly overheated and frequent on/off of the heater by rapid temperature variation can also be prevented, thereby preventing malfunction of the heater.
