Description

  The present invention relates to a refrigerator provided with a water cooler.

  Conventional refrigerators are disclosed in Patent Documents 1 to 3. The refrigerator includes a water cooler that takes water from the front of the door that opens and closes the storage chamber. The water cooler has a water tank disposed on the back of the door and a water intake portion disposed on the front surface of the door, and a water intake provided at the upper portion of the water intake portion is connected to the water tank by a water supply pipe penetrating the door. Yes. The water supply pipe is provided with a water stop valve, and an opening and closing part such as a lever for opening and closing the water stop valve is provided on the back surface of the water intake part.

  When water is poured into the water tank and the door is closed, the water in the water tank is cooled. When the user installs a container such as a cup below the water intake and presses the opening / closing part, the water stop valve is opened. Thereby, the cold water in a water tank can be taken in in a container via a water intake. And if a container is separated from an opening-and-closing part, a water stop valve will be closed.

Japanese Patent Laid-Open No. 9-126650 (page 3 to page 6, FIG. 2) Japanese Patent Laid-Open No. 9-229531 (pages 3 to 4 and FIG. 2) Japanese Patent Laying-Open No. 2006-153366 (page 3 to page 6, FIG. 1)

  However, according to the conventional refrigerator, when a user removes a container such as a cup after water removal, water remaining in the water supply pipe drops from the water intake. At this time, the water dripped from the water intake port rebounds at the bottom surface composed of the horizontal surface of the water intake part. At this time, since the dripped water bounces back in all directions on the bottom surface of the water intake section, there is a problem that the floor surface is submerged by water that bounces forward and exceeds the water intake section.

  An object of this invention is to provide the refrigerator provided with the water cooler which can prevent the flooding of a floor surface.

  In order to achieve the above-mentioned object, the present invention provides a water intake portion, which is provided with an intake port connected to a water tank provided in a storage chamber at the top, and is recessed in the front surface of the door of the storage chamber. In a refrigerator including a water cooler for taking water in a tank, a reflection part is provided that reflects water dripped from the water intake toward a back wall of the water intake part.

  According to this configuration, when water is poured into the water tank and the door is closed, the water in the water tank is cooled. Cold water is taken from a water intake opened by a predetermined operation by placing a container such as a cup in the water intake. The water dripped from the water intake port when the container after water intake is separated is reflected by the reflecting portion toward the back wall of the water intake portion and is prevented from bouncing forward.

  Moreover, the present invention is characterized in that, in the refrigerator having the above-described configuration, the reflecting portion is formed by a protruding portion that protrudes from the bottom surface of the water intake portion and has an upper surface formed on an inclined surface that is lowered rearward. According to this structure, the protrusion part which comprises a reflection part protrudes from the bottom face of a water intake part. The upper surface of the protruding portion is formed on an inclined surface that is lowered rearward, and water dripped from the water intake port is reflected by the inclined surface toward the back wall of the intake portion.

  Moreover, the present invention is characterized in that, in the refrigerator having the above-described configuration, the reflecting portion is formed of a bottom surface of the water intake portion formed on an inclined surface whose rear side is lowered. According to this configuration, the bottom surface of the water intake unit is formed as an inclined surface with the rear side falling to configure the reflection unit. Water dripped from the water intake is reflected by the inclined surface toward the back wall of the water intake.

  Moreover, the present invention is characterized in that, in the refrigerator having the above-described configuration, the reflecting portion includes a reflecting rib that protrudes from the bottom surface of the water intake portion and covers at least the front in the vicinity immediately below the water intake port. According to this structure, the reflection rib which comprises a reflection part protrudes from the bottom face of a water intake part. The reflection rib is formed in, for example, an arch shape covering the front in the vicinity of the portion directly below the water intake. The water dripped from the water intake port is reflected on the bottom surface of the water intake part, and the water droplets reflected forward are further reflected backward by the reflection rib.

  Further, in the refrigerator having the above-described configuration, the present invention is configured such that a shielding rib for preventing water from flowing from the bottom surface of the water intake portion is provided so as to protrude from the front surface of the bottom surface of the water intake portion so that the shielding rib is higher than the reflection portion. It is a feature. According to this configuration, the water dripped onto the bottom surface of the water intake unit is accumulated at the bottom of the water intake unit by the shielding of the shielding ribs protruding from the front part, and flowing water from the bottom surface of the water intake unit is prevented. A water droplet that drops from the water intake and reflects forward is blocked by a higher shielding rib than the reflecting portion.

  Moreover, the present invention is characterized in that, in the refrigerator having the above-described configuration, the bottom surface of the water intake section is formed by a detachable water tray. According to this structure, the water dripped at the bottom surface of the water intake unit is stored in the water receiving tray, and is drained by removing the water receiving tray.

  According to the present invention, since the reflecting portion that reflects the water dripped from the water intake port disposed on the upper portion of the water intake portion toward the back wall of the water intake portion is provided, it is possible to prevent the water rebound from the water intake portion from moving forward. Therefore, the floor surface can be prevented from being flooded.

The perspective view which shows the water intake part of the water cooler of the refrigerator of 3rd Embodiment of this invention.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing the refrigerator of the first embodiment. The refrigerator 1 is provided with a freezer compartment 2 at the top and a refrigerator compartment 3 below the freezer compartment 2. The front surfaces of the freezer compartment 2 and the refrigerator compartment 3 are opened and closed by doors 2a and 3a, respectively. A water intake portion 11 of the water cooler 10 is recessed in the front surface of the door 3 a of the refrigerator compartment 3.

  FIG. 2 is a perspective view showing a state in which the doors 2a and 3a of the refrigerator 1 are opened. A plurality of door pockets 4 are provided on the back side of the door 3a of the refrigerator compartment 3, and a water tank 13 of the water cooler 10 is disposed on the upper stage. A water supply pipe 12 is led out to the bottom of the water tank 13.

  The water tank 13 has a water storage part 14 that opens the upper surface and stores water, and a detachable lid part 15 that covers the upper surface of the water storage part 14. The water reservoir 14 can be cleaned by removing the lid 15. A water inlet (not shown) for injecting water into the water reservoir 14 is opened on the lid 15, and an opening / closing member 18 that slides to open and close the water inlet is attached.

  FIG. 3 is a side sectional view showing details of the water intake section 11 of the water cooler 10. A frame 22 made of a resin molded product is fixed to the front surface of the frame portion 21 by engagement with an engagement claw (not shown). The frame 22 forms the back wall 11 b of the water intake unit 11. The upper portion of the frame 22 is opened, and the lever holding portion 23 is screwed to the frame portion 21. The lever holding part 23 pivotally supports a lever 34 having a shaft part 34a at the upper part. As will be described later, the lever 34 extends downward and rotates when pressed. Concave portions 21b and 22a for avoiding interference with the lever 34 rotated rearward are provided at the center of the frame portion 21 and the frame 22 in the left-right direction.

  The lever holding portion 23 pivotally supports the arm 35 above the shaft portion 34 a of the lever 34. The arm 35 is formed in an L-shaped cross section with the rear end bent downward, and the rear end surface abuts the upper portion of the shaft portion 34 a of the lever 34. The front portion of the arm 35 is formed in a U shape in plan view with an opening at the front, and engages with an engagement protrusion (not shown) protruding from the peripheral surface of the nozzle 30.

  A valve holding part 24 is screwed to the upper part of the lever holding part 23 from the front. The pipe part 24a on the back surface of the valve holding part 24 is inserted into insertion holes 23a, 21a provided in the lever holding part 23 and the frame part 21, and is connected to the water supply pipe 12 through the door 3a. The front portion of the valve holding portion 24 is bent downward, and a sleeve 25 is screwed to the opening surface at the tip via an O-ring 26.

  The lower portion of the sleeve 25 has a reduced diameter portion 25a which is reduced in diameter below the valve holding portion 24, and the valve 32 is inserted into the reduced diameter portion 25a. The valve 32 forms radial passages between the ribs in the reduced diameter portion 25a by radial ribs (not shown), and a flange portion 32a having an enlarged diameter is formed at the upper end. A compression spring 33 is provided between the upper end surface of the valve 32 and the inner surface of the valve holding portion 24, and the valve 32 is urged downward. Thereby, the collar part 32a contacts the upper end surface of the reduced diameter part 25a via the O-ring 31, and the water from the water tank 13 is stopped.

  When the lower portion of the lever 34 is pressed rearward, the arm 35 that contacts the upper portion of the lever 34 rotates counterclockwise in the drawing. As a result, the nozzle 30 in contact with the arm 35 is pushed upward together with the valve 32 against the urging force of the compression spring 33, and the water from the water tank 13 flows out from the water intake 30 a of the nozzle 30.

  The opening surface of the water intake 30a of the nozzle 30 is inclined so that the rear side is lowered. For this reason, the water remaining in the nozzle 30 or the like when the water is stopped is dripped from the rear end of the water intake 30a. Further, the valve holder 24 can be removed integrally with the valve 32 and the nozzle 30 by removing the screw from the front. Thereby, it is possible to remove dust between the valve 32 and the sleeve 25 and replace the O-rings 26 and 31.

  A front cover 27 attached to the frame 22 is disposed on the front upper portion of the water intake unit 11. The front cover 27 covers the front surfaces of the valve holding unit 24 and the nozzles 30 and covers the lower part of the nozzles 30 to conceal them, thereby improving the aesthetics of the water intake unit 11. In addition, an opening 27 a that faces the water intake port 30 a is formed on the lower surface of the front cover 27.

  The back portion of the frame 22 forming the back wall 11b of the water intake portion 11 has an inclined surface 22b whose horizontal cross section is an arc shape and whose lower portion is inclined forward. The inclined surface 22 b extends upward from the bottom of the water intake unit 11 and is formed to the vicinity of the nozzle 30. The frame portion 21 is formed to be inclined along the inclined surface 22b. For this reason, the thickness of the foam heat insulating material 3d on the back side of the water intake unit 11 can be increased, and the amount of protrusion on the back side of the door 3a can be reduced to ensure the heat insulation thickness.

  Moreover, the lower end of the inclined surface 22b and the lower end of the lever 34 are arranged behind the vertical line A passing through the rear end of the water intake 30a. Thereby, it is possible to prevent water droplets dripping from the rear end of the water intake port 30a from splashing back at the inclined surface 22b or the lever 34 and scattering forward from the water intake portion 11.

  FIG. 4 is a perspective view showing details of the water intake unit 11 of the water cooler 10. A detachable water receiving tray 40 is disposed at the bottom of the water intake portion 11, and the bottom surface 11 a of the water intake portion 11 is formed by the bottom surface of the water receiving tray 40. A shielding rib 40 a protruding upward is provided on the periphery of the water receiving tray 40. By the shielding rib 40a, water dripped from the water intake 30a can be stored in the water receiving tray 40 to prevent water from flowing from the water receiving tray 40.

  The water receiving tray 40 is provided with a protrusion 42 directly below the water intake 30a. The upper surface of the projecting portion 42 is formed by an inclined surface that is lowered rearward. For this reason, the water dripped from the water intake port 30 a is reflected backward by the protrusion 42. That is, the protrusion 42 constitutes a reflection part that reflects the water dripped from the water intake 30 a toward the back wall 11 b of the water intake part 11. Further, the shielding rib 40 a at the front end of the water tray 40 is formed higher than the front end of the protrusion 42.

  In the refrigerator 1 having the above-described configuration, the opening / closing member 18 is opened and water is poured from the water inlet into the water storage unit 14, and the opening / closing member 18 is closed. When the door 3a is closed, the water in the water reservoir 14 is cooled. When the user presses the lever 34 with a container such as a cup disposed in the water intake section 11, the valve 32 rises together with the nozzle 30. Thereby, the cold water in the water tank 13 is supplied into the container from the water intake 30a.

  When the container is released from the lever 34, the valve 32 is lowered to stop the water. At this time, water remaining in the nozzle 30 and the like is dripped from the water intake 30a. Water droplets dripping from the water intake 30a are reflected on the upper surface of the projection 42 in the direction of the back wall 11b of the water intake 11. Thereby, the splash of the water ahead of the water intake part 11 can be prevented. Further, even if a part of the water droplet is reflected forward by the protrusion 42, it is shielded by the shielding rib 40 a higher than the protrusion 42 and returned to the water tray 40.

  According to the present embodiment, since the protrusion 42 (reflecting part) that reflects the water dripped from the water intake port 30a disposed on the upper part of the water intake part 11 toward the back wall 11b of the water intake part 11 is provided, the water intake part 11 It is possible to prevent the water from bouncing forward. Therefore, the floor surface can be prevented from being flooded.

  Moreover, the reflection part which reflects the water dripped from the water intake port 30a toward the back wall 11b of the water intake part 11 can be easily realized by making the upper surface of the protrusion part 42 an inclined surface with the rear side lowered.

  Moreover, since the shielding rib 40a which prevents the flowing water from the water receiving tray 40 is projected on the front surface of the bottom surface 11a of the water portion 11 and the shielding rib 40a is made higher than the protruding portion 42, the floor surface is more reliably prevented from being flooded. can do.

  Moreover, since the removable water receiving tray 40 was provided, the water dripped from the water intake 30a can be stored in the water receiving tray 40, and the water receiving tray 40 can be removed and drained or cleaned. Therefore, the water intake unit 10 can be kept clean.

  Moreover, since the back wall 11b of the water intake part 11 of the water cooler 10 has an inclined surface 22b whose lower side is inclined forward, a sufficient heat insulating thickness is secured on the back side of the inclined surface 22b to prevent condensation, and the door 3a. The amount of protrusion on the back side of can be reduced. In addition, the water droplets reflected by the protrusions 42 and hitting the inclined surface 22b have more scattered energy than if they hit the vertical surface. For this reason, it is possible to prevent water droplets bounced off the back wall 11b from being scattered forward of the water intake section 11.

  Next, FIG. 5 is a perspective view showing a water intake portion of the refrigerator water cooler of the second embodiment. For convenience of explanation, the same parts as those in the first embodiment shown in FIGS. In the present embodiment, the protrusion 42 (see FIG. 4) of the first embodiment is omitted, and the configuration of the bottom surface 11a of the water intake unit 11 is different. Other parts are the same as those in the first embodiment.

  The bottom surface 11a of the water intake portion 11 formed of the upper surface of the water receiving tray 40 is formed as an inclined surface that is lowered rearward. For this reason, the water dripped from the water intake 30a is reflected backward by the bottom surface 11a. That is, the bottom surface 11 a of the water intake unit 11 constitutes a reflection unit that reflects water dripped from the water intake port 30 a toward the back wall 11 b of the water intake unit 11.

  Further, the front shielding rib 40 a is provided so as to protrude upward from the front end of the bottom surface 11 a of the water intake portion 11. For this reason, even if a part of the water droplet is reflected forward by the bottom surface 11a, it is shielded by the shielding rib 40a and returned to the water tray 40.

  According to the present embodiment, as in the first embodiment, the water dripped from the water intake port 30a disposed on the upper part of the water intake unit 11 is taken toward the back wall 11b of the water intake unit 11 by the bottom surface 11a (reflecting part) of the water intake unit 11. Therefore, it is possible to prevent the water from bouncing forward from the water intake section 11. Therefore, the floor surface can be prevented from being flooded.

  Moreover, the reflection part which reflects the water dripped from the water intake 30a toward the back wall 11b of the water intake part 11 can be easily realized by making the bottom surface 11a of the water intake part 11 an inclined surface with the rear side falling.

  Moreover, since the shielding rib 40a is higher than the bottom surface 11a of the water intake part 11, the floor surface can be more reliably prevented from being flooded.

  Next, FIG. 6 is a perspective view showing a water intake portion of the water cooler of the refrigerator of the third embodiment. For convenience of explanation, the same parts as those in the first embodiment shown in FIGS. In the present embodiment, the protrusion 42 (see FIG. 4) of the first embodiment is omitted, and the configuration of the bottom surface 11a of the water intake unit 11 is different. Other parts are the same as those in the first embodiment.

  On the bottom surface 11a of the water intake section 11 formed from the upper surface of the water receiving tray 40, an arch-shaped reflection rib 43 is projected. The reflecting rib 43 is slightly larger than the size of the water intake 30a projected on a plane, and is disposed in the vicinity of the water intake 30a in the vertical direction. For this reason, the water dripped from the water intake 30 a is reflected by the bottom surface 11 a, and the water droplets reflected forward are reflected back again by the reflection rib 43. That is, the reflection rib 43 constitutes a reflection part that reflects water dripped from the water intake 30 a toward the back wall 11 b of the water intake part 11.

  At this time, since the reflecting rib 43 is arranged in the vicinity of the vertical bottom of the water intake port 30a, water droplets reflected by the bottom surface 11a collide with the reflecting rib 43 at a low height. Thereby, the water droplet exceeding the reflective rib 43 can be reduced.

  Further, the shielding rib 40 a is formed higher than the reflecting rib 43. For this reason, even if a part of water droplets reflected forward by the bottom surface 11 a exceeds the reflecting rib 43, it is shielded by the shielding rib 40 a and returned to the water tray 40.

  According to the present embodiment, as in the first embodiment, the water dripped from the water intake port 30a disposed on the upper portion of the water intake unit 11 is reflected toward the back wall 11b of the water intake unit 11 by the reflective rib 43 (reflective unit). Therefore, it is possible to prevent the water from bouncing forward from the water intake unit 11. Therefore, the floor surface can be prevented from being flooded.

  Further, it is possible to easily realize a reflecting portion that reflects the water dripped from the water intake port 30a toward the back wall 11b of the water intake portion 11 by the reflecting rib 43. In addition, the reflection rib 43 can prevent scattering of water droplets forward by covering at least the front immediately below the water intake 30a.

  Moreover, since the shielding rib 40a is higher than the reflecting rib 43, the floor surface can be more reliably prevented from being flooded.

  According to this invention, it can utilize for the refrigerator provided with the water cooler.
