The washing machine comprises a tub installed in a body of the washing machine to contain water, and a fixing bracket positioned on a rear wall of the tub to prevent movement of at least one hall sensor wire connected with a hall sensor serving to detect a speed of a motor installed on the rear wall of the tub.
Description
- The present invention relates to a washing machine, and more particularly, to a washing machine, which has structure to prevent a hall sensor wire connected with a hall sensor serving to detect a rotating speed of a motor from freely moving due to vibration transmitted from a tub when washing laundry, thereby preventing damage or disconnection of the hall sensor wire.
- Generally, washing machines are classified into pulsator type washing machines which wash laundry using water motion generated by rotating a plate-shaped pulsator, and drum type washing machines which wash the laundry using falling of water and the laundry and frictional force therebetween generated within a horizontally laid tub by rotating the tub.
- Among these washing machines, the drum type washing machine has been increasingly demanded in recent years due to its merits over the pulsator type washing machine in that the drum type washing machine uses a smaller amount of water and detergent, and is substantially free from damage and entanglement of the laundry when washing the laundry.
- Referring to
FIGS. 1 and 2 , construction of a conventional drum type washing machine will be described in detail as follows. -
FIG. 1 is a longitudinal section view illustrating construction of a conventional drum type washing machine, which comprises atub 2 positioned within acabinet 1, a drum rotatably installed at an inner center of thetub 2, and a controller 7 positioned at an upper portion of thecabinet 2 to control operation of the washing machine. - A
motor 5 of the washing machine is positioned at a rear side of thetub 2, and comprises astator 5 a secured to a rear wall of thetub 2 and arotor 5 b which penetrates thetub 2 and is connected with the drum 3 via ashaft 4 while surrounding thestator 5 a. - The
motor 5 is provided at one side with ahall sensor 9 to detect a speed of themotor 5, and ahall sensor wire 9 a positioned at a lower side of the rear wall of thetub 2 and connected with thehall sensor 9 to supply power to thehall sensor 9 or to allow thehall sensor 9 to be controlled by the controller 7. - The
hall sensor wire 9 a is connected with thehall sensor 9 via a hallsensor connecting member 9 b. - Meanwhile, a
door 21 is installed on a front side of thecabinet 1, and agasket 22 is installed between thedoor 21 and thetub 2. - In addition, a hanging
spring 23 is installed between an inner side of an upper surface of thecabinet 1 and an upper side of an outer periphery of thetub 2 to hold thetub 2, and afriction damper 24 is installed between an inner side of a lower surface of thecabinet 1 and a lower side of an outer periphery of thetub 2 to damp vibration of thetub 2 that occurs upon spin drying. - Operation of the conventional drum type washing machine will be described hereinafter.
- When power is applied to the
stator 5 a of themotor 5 with the drum 3 filled with water and detergent, therotor 5 b is rotated. Rotation of therotor 5 b causes theshaft 4 to be rotated, and in turn, causes rotation of the drum 3. - Then, laundry contained in the drum 3 is washed by virtue of water and friction between the laundry and the drum 3.
- The conventional drum type washing machine has a problem as follows.
- For the conventional drum type washing machine, when driving the
motor 5 for operation of the washing machine, vibration is generated, and transmitted to thetub 2, causing thehall sensor wire 9 a positioned on the rear wall of the tub to move. As a result, there is possibility that displacement of thehall sensor wire 9 a with respect to thetub 2 becomes significantly enlarged. - As the displacement of the
hall sensor wire 9 a with respect to thetub 2 becomes significantly enlarged, load is applied to the connectingmember 9 b of thehall sensor wire 9 a so that the connectingmember 9 b of thehall sensor wire 9 a is damaged, or thehall sensor wire 9 a is disconnected. - Furthermore, the disconnection of the
hall sensor wire 9 a can cause short circuit, and result in fire. - An object of the present invention devised to solve the problem lies on a washing machine, which has a hall sensor wire stably secured to a tub on a rear wall of the tub, thereby preventing the hall sensor wire from freely moving due to vibration transmitted from the tub when operating the washing machine.
- The objects of the present invention can be achieved by providing a washing machine, comprising: a tub installed in a cabinet of the washing machine to contain water; and a fixing bracket positioned on a rear wall of the tub to prevent movement of a hall sensor wire connected with a hall sensor serving to detect a speed of a motor installed on the rear wall of the tub.
- The fixing bracket may comprise a body defining an outer appearance of the fixing bracket and having a recess formed thereon to receive the hall sensor wire, and a fixing part formed at one end of the body and having at least one fastening hole formed therein to secure the body.
- The recess may have both circumferences rounded outwardly, and the fixing bracket may have all circumferences rounded outwardly.
- The fixing bracket may be secured to the rear wall of the tub by means of a one-point fastening structure.
- The washing machine may further comprise a rotation preventing device formed on the fixing bracket and the rear wall of the tub to prevent the fixing bracket from rotating.
- The rotation preventing device may comprise a rotation preventing protrusion formed on the tub, and an insertion hole formed through the fixing bracket so as to allow the rotation preventing protrusion to be inserted therein.
- The rotation preventing device may comprise a rotation preventing protrusion formed on the fixing bracket, and an insertion hole formed on the tub so as to allow the rotation preventing protrusion to be inserted therein.
- The washing machine may further comprise a fixing device formed on the rear wall of the tub to fix remaining portions of the hall sensor wire secured to the fixing bracket.
- The fixing device may comprise a pair of protrusions formed on the rear wall of the tub so as to allow the hall sensor wire to be fitted between the pair of protrusions.
- With this construction, the present invention has advantageous effects as follows.
- Firstly, according to the present invention, with the structure of the hall sensor wire secured to the rear wall of the tub, a large displacement of the hall sensor wire with respect to the rear wall of the tub can be prevented from occurring due to vibration transmitted from the tub when operating the drum type washing machine, thereby solving problems such as damage or disconnection of the hall sensor wire.
- In this regard, since a short circuit caused by the disconnection of the hall sensor wire is prevented, it is possible to prevent fire from occurring.
- Secondly, according to the present invention, with the structure of the fixing bracket having the circumferences rounded outwardly, the hall sensor wire can be prevented from being worn out even with continuous contact of the hall sensor wire with the circumferences of the fixing bracket, thereby preventing a cover of the hall sensor wire from being worn out.

FIGS. 3 to 5 , the drum type washing machine according to the embodiment comprises atub 2 positioned within acabinet 1, a drum rotatably installed at an inner center of thetub 2, and a controller 7 positioned at an upper portion of thecabinet 2 to control operation of the washing machine. - In addition, a
motor 5 of the washing machine is positioned at a rear side of thetub 2, and comprises astator 5 a secured to a rear wall of thetub 2 and arotor 5 b which penetrates thetub 2 and is connected with the drum 3 via ashaft 4 while surrounding thestator 5 a. - The
motor 5 is provided at one side with ahall sensor 9 to detect a speed of themotor 5, and ahall sensor wire 9 a positioned at a lower side of the rear wall of thetub 2 and connected with thehall sensor 9 to supply power to thehall sensor 9 or to allow thehall sensor 9 to be controlled by the controller 7. - The
hall sensor wire 9 a is connected with thehall sensor 9 via a hallsensor connecting member 9 b. - Meanwhile, a
door 21 is installed on a front side of thecabinet 1, and agasket 22 is installed between thedoor 21 and thetub 2. - In addition, a hanging
spring 23 is installed between an inner side of an upper surface of thecabinet 1 and an upper side of an outer periphery of thetub 2 to hold thetub 2, and afriction damper 24 is installed between an inner side of a lower surface of thecabinet 1 and a lower side of an outer periphery of thetub 2 to damp vibration of thetub 2 that occurs upon spin drying. - According to the embodiment, a
fixing bracket 100 is installed to the rear wall of thetub 2 to prevent ahall sensor wire 9 a from moving due to vibration transmitted from the tub when driving themotor 5. Thefixing bracket 100 comprises abody 110, and afixing part 130 to secure thebody 110. - The
body 110 is adapted, for example, to define an outer appearance of thefixing bracket 100, and preferably has arecess 111 to allow ahall sensor wire 9 a to be seated on therecess 111. - The
fixing part 130 serves to secure thebody 110 to the rear wall of thetub 2, and preferably has at least onefastening hole 131 formed therethrough so as to allow a screw S to be fastened to thetub 2 therethrough. - Meanwhile, the
recess 111 preferably has both circumferences rounded outwardly. More preferably, thefixing bracket 100 has all circumferences rounded outwardly. - More specifically, for the conventional drum type washing machine, the cover of the
hall sensor wire 9 a can being worn out or damaged due to continuous contact of thehall sensor wire 9 a with the circumference of thefixing bracket 100 when driving themotor 20, thereby causing a short circuit. On the contrary, according to the present invention, the circumference of thefixing bracket 100 is rounded outwardly in order to prevent this phenomenon. - According to the embodiment, the
fixing bracket 100 may be secured to the rear wall of the tub by means of a one-point fastening structure, which may be a screw S. To this end, preferably, thefixing part 130 is formed with onefastening hole 131, and the rear wall of the tub is formed with one fastening groove (not shown) corresponding to thefastening hole 131. - Meanwhile, the washing machine may further comprise a
rotation preventing device 300 formed on the fixingbracket 100 and the rear wall of thetub 2 to prevent the fixingbracket 100 from rotating. - More specifically, if vibration from the motor becomes severe, the fixing,
bracket 100 fixed to the rear wall of thetub 2 via the one-point fastening structure may be rotated to one side along with thehall sensor wire 9 a by the vibration. - The
rotation preventing device 300 prevents rotation of the fixingbracket 100. - According to the embodiment, the
rotation preventing device 300 may comprise arotation preventing protrusion 310 formed on thetub 2, and aninsertion hole 330 formed through the fixingbracket 100 so as to allow therotation preventing protrusion 310 to be inserted therein. - Although not shown in the drawings, the
rotation preventing protrusion 310 may be formed on the fixingbracket 100, and the insertion hole may be formed on thetub 2 so as to allow the rotation preventing protrusion to be inserted therein. - According to the embodiment, the washing machine may further comprise a

device 500 may comprises a pair ofprotrusions hall sensor wire 9 a to be fitted between theprotrusions - A method of securing a
hall sensor wire 9 a using afixing bracket 100 and afixing device 500 according to the present invention, and effect thereof will be described hereinafter. - First, a
hall sensor 5 to detect a speed of amotor 5 is assembled to the rear wall of atub 2 along with themotor 5 when assembling the washing machine of the invention. - Next, a
hall sensor wire 9 a connected with thehall sensor 9 via a hallsensor connecting member 9 b is positioned at a lower side on the rear wall of thetub 2 such that thehall sensor 9 is supplied with electric current through thehall sensor wire 9 a, or controlled by a controller 7. - Then, the
hall sensor wire 9 a is secured to the rear wall of thetub 2 by means of a fixingbracket 100. - At this time, a securing position of the
hall sensor wire 9 a is placed by seating thehall sensor wire 9 a in arecess 111 formed on abody 110 of the fixingbracket 100 while inserting arotation preventing protrusion 310 formed on the rear wall of thetub 2 into aninsertion hole 330 formed through a fixingpart 110 of the fixingbracket 100. - Then, the fixing
bracket 100 is secured to the rear wall of thetub 2, with thehall sensor wire 9 a fixed thereto, by fastening a screw S to a fastening groove (not shown) formed on the rear wall of thetub 2 through afastening hole 131 formed through the fixingpart 130. - Next, a remaining portion of the
hall sensor wire 9 a between the fixingbracket 100 and thehall sensor 9 is fitted and secured betweenprotrusions fixing device 500. - With a series 6 f steps described above, the
hall sensor wire 9 a is firmly secured to the rear wall of thetub 2 by means of the fixingbracket 100 and the fixingdevice 500. - In the drum type washing machine constructed as described above, the
hall sensor wire 9 a is stably secured to the rear all of thetub 2 by the fixing bracket and the fixing device so that displacement of thehall sensor wire 9 a with respect to thetub 2 can be prevented from being enlarged due to vibration transmitted from thetub 2 when operating the washing machine. - In other words, if the
hall sensor wire 9 a moves to generate large displacement with respect to thetub 2, a load is applied to the connectingmember 9 b of thehall sensor wire 9 a, thereby possibly causing damage or disconnection of the connectingmember 9 b. However, according to the invention, since thehall sensor wire 9 a is secured to the rear wall of thetub 2, thehall sensor wire 9 a can vibrate along with thetub 2 so that the displacement of thehall sensor wire 9 a with respect to thetub 2 becomes negligible, and thus a high load is prevented from being applied to the connectingmember 9 b of thehall sensor wire 9 a, thereby preventing disconnection of thehall sensor wire 9 a. - In addition, with the structure of the fixing
bracket 100 having the circumference rounded outwardly, thehall sensor wire 9 a can be prevented from being worn out even with continuous direct contact of thehall sensor wire 9 a with the circumference of the fixingbracket 100, which prevents a cover of thehall sensor wire 9 a from being worn out as well as a short circuit caused thereby. - It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention.
