- 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. 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.
- Another aspect of the present invention is to provide a washing machine that can forcibly circulate heated wash water.
- According to an aspect of the present invention, 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 heater cover may be made of a thermally resistant material.
- The above and other aspects, features and advantages of the present invention will become apparent from the following description of a preferred embodiment given in conjunction with the accompanying drawings, in which:

tub 110 to absorb vibration or impact caused by rotation of thedrum 111 or by laundry falling within thedrum 111. - The
tub 110 has aprotrusion 115 formed on a lower side of thetub 110. That is, theprotrusion 115 is formed on an outer lower surface of thetub 110. Theheater cover 120 is located within theprotrusion 115. Theheater cover 120 is configured to surround theheater 130 while preventing theheater 130 from contacting thetub 110. Theheater cover 120 may be formed to surround upper and lower sides of theheater 130, or to surround the entirety of the heater at a distance from theheater 130, as shown inFig. 2 . Since theheater 130 is located within theheater cover 120, theheater cover 120 may be formed of a thermally resistant material. In this embodiment, theheater cover 120 is made from a SUS material which is resistant to moisture and heat. - The
heater cover 120 is formed with apenetration hole 121 which is in communication with thetub 110. Wash water flows into the heater cover 120 through thepenetration hole 121 or flows from theheater cover 120 through thepenetration hole 121 after being heated. Further, theheater cover 120 is formed with aninsertion hole 123 into which theheater 130 is inserted. - In this embodiment, the
heater 130 is secured to thetub 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.

pump 140 forces wash water received in thetub 110 to move. Thepump 140 is in communication with theprotrusion 115 through amovement pipe 141. Further, thepump 140 is in communication with an upper side of thetub 110 through acirculation pipe 143 and is in communication with the outside of the washing machine through adischarge pipe 145. Wash water introduced into thepump 140 is selectively moved to thecirculation pipe 143 or thedischarge pipe 145 by aselective blocking part 150. - Wash water heated during a washing cycle is moved to the
tub 110 through themovement pipe 141,pump 140 andcirculation pipe 143 by operation of thepump 140. Accordingly, the wash water heated by theheater 130 is circulated not only by convection, but is also forcibly circulated by thepump 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 theheater 130 by preventing the wash water near theheater 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 thecirculation pipe 143 and thedischarge pipe 145. In this embodiment, theselective blocking part 150 includes a blockingmember 151 and anarm 153. The blockingmember 151 selectively blocks thecirculation pipe 143 and thedischarge pipe 145 to allow wash water to be introduced into thetub 110 through thecirculation pipe 143 or to be discharged outside through thedischarge pipe 145. Thearm 153 is mounted on the blockingmember 151, and selectively opens or closes thecirculation pipe 143 or thedischarge pipe 145 in association with a left or right movement of the blockingmember 151. In this embodiment, theselective blocking part 150 is a hydraulic cylinder. However, theselective blocking part 150 can be modified in various forms such as solenoid valves and the like. - As apparent from the above description, according to an embodiment of the invention, the washing machine may prevent fire and damage of a tub even when a heater is separated from the tub.
- According to the embodiment of the invention, the washing machine heats wash water while circulating the wash water, thereby preventing the wash water from being rapidly overheated.
- According to the embodiment of the invention, the washing machine heats wash water while circulating the wash water, thereby reducing heating time.
- According to the embodiment of the invention, 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.
- Although the present invention has been described with reference to the embodiments and the accompanying drawings, these are given by way of illustration only, and, it will be apparent to those skilled in the art that various modifications and other equivalent embodiments can be made without departing from the scope of the present invention. Therefore, the scope and spirit of the invention should be limited only by the claims set forth as follows.
