Description
- The present disclosure relates a sensor fixing member and a dishwasher including the same.
- A dishwasher is a home appliance configured to wash off contaminants such as food scraps or waste on dishes by automatically spraying washing water. In detail, a nozzle disposed inside the dishwasher sprays washing water while rotating, and the sprayed washing water directly collides with dishes to wash dishes by friction. Hereinafter, the internal structure of a dishwasher and detailed operation method of the dishwasher will be described.
-
FIG. 1 is a perspective view of a dishwasher in a state where a door of the dishwasher is open. Referring toFIG. 1 , the exterior of the dishwasher is composed of acase 10 with an open front and adoor 20 for sealing and opening the open front of the case. When thedoor 20 is open, an angle between thedoor 20 and thecase 10 may form a right angle of 90 degrees. Thedoor 20 may include adoor panel 22 provided therein and adoor cover 24 for covering the door panel. The interior of the dishwasher is composed of atub 30 for holding washing water, asump 40 provided below thetub 30 and spraying the washing water after collecting the washing water and filtering foreign substances, alower nozzle 50 and alower nozzle 52 spraying the washing water into the tub while rotating with being connected with the sump, arack 70 on which dishes are stored, and adetergent dispenser 60 attached to an upper end of thedoor panel 22 and guiding an introduced detergent into the tub. - The
detergent dispenser 60 may introduce a detergent while thedoor 20 is open. When thedoor 20 is closed, the detergent introduced as a detergent introduction opening cover is open based on processes of the dishwasher is guided below the tub mounted inside the dishwasher. The guided detergent is mixed with the washing water collected in thesump 40 and the washing water mixed with the detergent is sprayed through the nozzles to wash the dishes stored in therack 70 provided in the tub. - Meanwhile, since the nozzles spray washing water while rotating, there is a problem in that the rotation of the nozzles is restricted for various reasons. For example, when foreign substances are caught in the nozzles or the dishes stored on the
rack 70 collide with the nozzles after protruding downward from the rack, the rotation of the nozzles could be restricted. - A nozzle restriction detecting sensor may be used to detect the rotation restriction of the nozzles. However, when the nozzle restriction detecting sensor is disposed inside the tub, there is a possibility that the nozzle restriction detecting sensor might be damaged by foreign substances and washing water.
- In addition, to dispose the nozzle restriction detecting sensor in the door in order to prevent damage to the nozzle restriction detecting sensor, an additional process of molding the conventional door panel should be preceded. For example, there are works such as drilling new holes in the door panel, using molds or welding new structures.
- Such a method cannot use the conventional door panel as it is, and it requires a separate installation cost for a sensor fixing member configured to detect nozzle restriction. In addition, there is a problem in that the conventional door panel has to be damaged during the process of installing the sensor.
- An objective of the present disclosure is to provide a fixing member of a nozzle restriction detecting sensor that may improve washing efficiency by immediate action after detecting whether a nozzle operates normally, and a dishwasher including the sensor fixing member.

Due to this structure, the nozzlerestriction detecting sensor 200 has to be provided at a height that is the same as the height from a bottom surface of the sensing target device provided in the nozzle.FIG. 7 is a view showing a method of coupling the sensor fixing member according to the embodiment of the present disclosure to the detergent dispenser.FIG. 8 is a side view showing a process of coupling the sensor fixing member according to the embodiment of the present disclosure to the detergent dispenser. Hereinafter, referring toFIGS. 7 and8 , the process of coupling the sensor fixing member to the detergent dispenser will be described. - Referring to
FIG. 7 , theanti-falling support 211 of thesensor fixing member 210 may be coupled to thesupport hanger 61 of thedetergent dispenser 60 first to couple the sensor fixing member to thedetergent dispenser 60. - When the
anti-falling support 211 is coupled to an upper area of thedetergent dispenser 60, theanti-falling support 211 may support thesensor fixing member 210 to prevent thesensor fixing member 210 from falling off from thedetergent dispenser 60 due to the gravity. In addition, thesupport hanger 61 may prevent the releasing of the coupling between theanti-falling support 211 and thedetergent dispenser 60. - Meanwhile, the nozzle
restriction detecting sensor 200 provided in thesensor fixing member 210 may be disposed at the height corresponding to the height of the nozzle from the bottom surface. Specifically, the nozzle may include an upper nozzle 522 or alower nozzle 50. Hereinafter, the nozzle will be described on the premise that theupper nozzle 52 is used. - The
upper nozzle 52 may include asensing target device 54 that is a target to be detected by the nozzlerestriction detecting sensor 200.

sensing target device 54 may be a magnet or a magnetic material. The nozzlerestriction detecting device 200 may be a hall sensor or a coil sensor. In other words, the nozzlerestriction detecting sensor 200 may be an element of which voltage changes according to the strength of the magnetic field. Thesensing target device 54 attached to theupper nozzle 52 around the nozzlerestriction detecting sensor 200 may detect the rotation speed of theupper nozzle 52 based on a potential difference generated when thesensing target device 54 moves along the rotation of theupper nozzle 52. - If the measured rotational speed of the
upper nozzle 52 is 0 or lower than a preset normal rotational speed, it may be determined that theupper nozzle 52 is restricted. Accordingly, when it is determined that theupper nozzle 52 is restricted, immediate measures such as removal of foreign substances may be taken, thereby improving cleaning efficiency. - Next, referring to
FIG. 8 , theanti-falling support 211 may be first coupled to thesupport hanger 61 disposed in the upper area of thedetergent dispenser 60 and then rotate around thesupport hanger 61 so that the hooks of thesensor fixing member 210 and the hook hangers of thedetergent dispenser 60 may be coupled to each other in turn. - Specifically, the
first hook 212 may be coupled to thefirst hook hanger 62 and thesecond hook 213 may be coupled to thesecond hook hanger 63 in turn. After that, the sensor coupling portion may become in contact with thefirst surface 22a of thedoor panel 22 and thesensor fixing member 210 may be fixed to thedoor panel 22. - Meanwhile, in an embodiment of the present disclosure, even in a state where the
sensor fixing member 210 is coupled to thedetergent dispenser 60, themember fixing portion 210c may be spaced apart therefrom without contacting thefirst surface 22a of the door panel. - Accordingly, it may be possible to prevent an operation error of the nozzle
restriction detecting sensor 200 caused by vibration due to the operation of the dishwasher or a failure due to an impact caused by the nozzlerestriction detecting sensor 200 colliding with thedoor panel 22.FIG. 9 is a view showing a method of coupling a sensor fixing member according to another embodiment of the present disclosure to a screw hole of a door panel.FIG. 10 is a view showing a dishwasher in which the sensor fixing member according to the embodiment to a screw hole of a door panel.

In addition, thesensor fixing member 310 may include twomember fixing portions 310a including the first throughhole 310a and the second through hole 3 10b, respectively. Meanwhile, the nozzlerestriction detecting sensor 200 may detect the restriction of the nozzle by using asensing target device 54 provided in the nozzle. Accordingly, the nozzlerestriction detecting sensor 200 has to be disposed at a height corresponding to the height from the bottom surface of thesensing target device 54 in order to improve detecting sensitivity. Due to this structure, the height of the screw hole and the through hole may be determined to correspond to the height of the nozzlerestriction detecting sensor 200 from the bottom surface of the sensing target device of the nozzle, thereby minimizing a distance between the nozzlerestriction detecting sensor 200 and thesensing target device 54 and determining presence of nozzle restriction precisely. - The
sensor fixing member 310 may be fixed to thefirst surface 22a of the door panel by the first fixingmember 25a penetrating the first throughhole 312a and thefirst screw hole 23a and the second fixingmember 25b penetrating the second throughhole 312b and thesecond screw hole 23b. - The

FIG. 9 , thesensor coupling portion 310c may include a first sensor fixingsensor member 316 and a secondsensor fixing member 317. The nozzlerestriction detecting sensor 200 may be detachably coupled between the firstsensor fixing member 316 and the secondsensor fixing member 317. - The extending
portion 310b may be disposed between themember fixing portion 310a and thesensor coupling portion 310c, to constitute a part of thesensor fixing member 310. The width of the extendingportion 310b may be constant regardless of the position of themember fixing portion 310a, and the lengths of both sides of the extendingportion 310b with respect to themember fixing portion 310a may be the same. However, the shape of the extendingportion 310b may not be limited thereto. - Meanwhile, the nozzle
restriction detecting sensor 200 may detect the restriction of the nozzle by using thesensor target device 54 provided in the nozzle. Accordingly, the position of the nozzlerestriction detecting sensor 200 has to be equal to the position of thesensing target device 54 when thesensing target device 54 is disposed closest to thedoor panel 22. Due to this structure, the length of the extending portion may be determined in consideration of the position of the sendingtarget device 54 or the nozzlerestriction detecting sensor 200. - As shown in
FIG. 10 , thesensor fixing member 310 including themember fixing portion 310a, the extendingportion 310b and the sensor coupling portion 130c may be disposed between thedoor panel 22 and thedoor cover 24, thereby preventing physical collision with foreign substances or washing water and damage to the nozzle restriction detecting sensor. - In addition, the
