[0010] Hereinafter, embodiments will be described in detail with reference to the drawings. However, unnecessary detailed description may be omitted. For example, detailed description of already well-known matters or redundant description of substantially the same configuration may be omitted.

[0011] The accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0012] (Embodiment 1) Hereinafter, the first embodiment will be described with reference to FIGS.

[0013] [1-1.Configuration] Fig. 1 is a schematic cross-sectional view of dishwasher 40 of embodiment 1 as seen from the front. Fig. 2 is a schematic cross-sectional view of dishwasher 40 of embodiment 1 as seen from the side. Fig. 3 is a schematic cross-sectional view of another cross section of dishwasher 40 of embodiment 1 as seen from the side.

[0014] The main body 1 houses components such as a washing tank 2 for washing items such as dishes. The washing tank 2 is provided inside the main body 1 and houses items such as dishes. A placing section 23 is provided inside the washing tank 2 and is used to place items to be washed. The door 3 opens and closes an opening 3a on the front of the main body 1.

[0015] The cleaning nozzle 4 is rotatably mounted within the cleaning tank 2, and sprays cleaning water onto the object to be cleaned from multiple nozzles mounted on its surface. The cleaning pump 6 sprays the cleaning water from the cleaning nozzle 4. The cleaning pump 6 circulates the cleaning water within the cleaning tank 2 by spraying the cleaning water drawn in from the cleaning pump suction port 7 mounted in the water reservoir 5 at the bottom of the cleaning tank 2 from the cleaning nozzle 4.

[0016] The filter unit 8 captures foreign matter such as food residue contained in the washing water. The filter unit 8 includes a residue filter 9, a punched filter 10, a mesh filter 11, and a drain filter 12.

[0017] The residue filter 9 is made of resin or the like and is formed into a generally cylindrical shape. The residue filter 9 has a plurality of holes arranged in a lattice pattern to capture relatively large residue. A handle is provided on the top of the residue filter 9 so that the user can grasp it when removing the residue filter 9 and discarding the captured residue.

[0018] The punched filter 10 is formed into a flat shape from a resin or the like, and holes are made in it during molding. To circulate the cleaning water even when the residue filter 9 or mesh filter 11 becomes clogged, the cleaning water is configured to be able to flow into the water reservoir 5 from outside the opening of the residue filter 9, and the punched filter 10 is provided to capture the residue contained in the cleaning water that flows into the water reservoir 5 from outside the opening of the residue filter 9.

[0019] The mesh filter 11 is integrally molded with the punched filter 10 and is provided on the peripheral side of the residue filter 9. The mesh filter 11 has fine openings such as a plain woven wire mesh and captures fine residue that has passed through the residue filter 9.

[0020] The drainage filter 12 captures foreign matter contained in the drainage water.

[0021] After the object has been washed, the drain pump 13 drains the wash water to the outside. The drain pump 13 drains the wash water sucked in from the drain pump suction port 14 provided in the water reservoir 5 to the outside.

[0022] The turbidity detection unit 15 detects the turbidity of the wash water. The turbidity detection unit 15 has a light-emitting unit and a light-receiving unit. The light-receiving unit receives light emitted from the light-emitting unit and transmitted through the wash water, and measures the transmittance of the received light. The turbidity detection unit 15 detects the turbidity of the wash water based on the transmittance of light measured by the light-receiving unit. The turbidity detection unit 15 may detect the turbidity of the wash water by any method other than the transmitted light measurement method, for example, a scattered light measurement method or an integrating sphere measurement method.

[0023] The detergent tank 16 stores liquid detergent for washing the objects to be washed. The detergent tank 16 includes an upper detergent tank portion 16a provided inside the washing tub 2 and a lower detergent tank portion 16b provided outside and below the washing tub 2. Since the heavy detergent tank 16 is provided below the washing tub 2, the stability of the main body 1 can be improved. Furthermore, compared to when the detergent tank 16 is provided on the door 3 or the like, the stability of the main body 1 can be improved when opening and closing the door 3. This improves user convenience. Furthermore, since the detergent tank 16 is provided below the washing nozzle 4, more objects to be washed can be accommodated in the washing tub 2. The detergent tank 16 may be provided so that the top surface of the upper detergent tank portion 16a is lower than the washing nozzle 4.

[0024] A detergent inlet 16c is provided in the detergent tank upper portion 16a for injecting liquid detergent into the detergent tank 16. Because the detergent inlet 16c is provided inside the washing tub 2, the liquid detergent can be easily injected into the detergent tank 16. Furthermore, even if the liquid detergent is spilled around the detergent inlet 16c when being injected into the detergent tank 16, the liquid detergent will simply spill inside the washing tub 2, so no particular problem will occur. This improves user convenience.

[0025] The detergent inlet 16c is provided near the opening 3a for accommodating the object to be washed inside the washing tank 2. This allows the liquid detergent to be easily poured into the detergent tank 16, improving user convenience.

[0026] The detergent tank upper portion 16a is made of a transparent or translucent material, which allows the liquid detergent inside the detergent tank upper portion 16a to be seen, thereby preventing the liquid detergent from overflowing when pouring the liquid detergent into the detergent tank 16.

[0027] A float unit 17 having a float 17a for detecting the liquid detergent level in the detergent tank 16 is provided in the detergent tank lower part 16b. The float 17a includes a magnet and is configured to float on the liquid detergent. A reed switch 18 provided near the side of the detergent tank lower part 16b detects the position of the magnet included in the float 17a. This makes it possible to detect the liquid detergent level inside the detergent tank 16. When the remaining amount of liquid detergent inside the detergent tank 16 falls below a predetermined value, the control unit notifies the user of this and prompts them to refill the liquid detergent.

[0028] At least one of the detergent tank upper part 16a, the detergent tank lower part 16b, and the float unit 17 may be provided detachably. This allows the user to remove and wash these components, improving ease of maintenance.

[0029] The detergent pump 21 dispenses liquid detergent stored inside the detergent tank 16 into the washing tub 2. A detergent inlet 22 for dispensing liquid detergent into the washing tub 2 is provided at the bottom of the washing tub 2. The detergent inlet 22 is provided at a position higher than the liquid level of the washing water in the washing process. This prevents the washing water from flowing back toward the detergent pump 21. The detergent inlet 22 may be provided at a position higher than the water reservoir 5.

[0030] Filter 19a for capturing foreign matter is provided near detergent inlet 16c of detergent tank upper portion 16a. Filter 19b is provided below float unit 17. Filter 19c is provided below detergent tank lower portion 16b. This prevents foreign matter from being sucked into detergent pump 21, which could cause malfunction or damage to detergent pump 21. By providing filter 19c, it is possible to prevent foreign matter from being sucked into detergent pump 21 even if the user removes and washes float unit 17 and then installs float unit 17 without installing filter 19b. The mesh of filter 19a may be coarser than the mesh of filters 19b or 19c.

[0031] Note that, instead of or in addition to the detergent, the detergent tank 16 may store a treatment agent such as a rinse agent for accelerating the drying of the object to be washed. In this case, a treatment tank for storing the treatment agent may be provided instead of or in addition to the detergent tank 16. Also, instead of or in addition to the detergent pump 21, a treatment pump for automatically adding the treatment agent may be provided.

[0032] The control unit 20 controls the operation of the dishwasher 40. In the washing process and the rinsing process, the control unit 20 operates the washing pump 6 to spray washing water from the washing nozzle 4. In addition, in the washing process and the rinsing process, the control unit 20 operates a motor (not shown) for rotating the washing nozzle 4 to rotate the washing nozzle 4. In addition, in the washing process, the control unit 20 operates the detergent pump 21 to feed liquid detergent stored in the detergent tank 16 into the washing tub 2. In the drying process, the control unit 20 may control a heater (not shown) to heat the air in the washing tub 2.

[0033] The control unit 20 controls at least one of the washing process and the rinsing process according to the turbidity of the washing water detected by the turbidity detection unit 15. In the washing process or the rinsing process, the control unit 20 may increase the time of the washing process or the rinsing process, increase the number of times the washing process or the rinsing process is performed, increase the pressure of the washing water sprayed from the washing nozzle 4, increase the rotation speed of the washing nozzle 4, or increase the temperature of the washing water, as the turbidity of the washing water increases. If a function for automatically adding detergent to be used in the washing process is provided, the control unit 20 may add a larger amount of detergent as the turbidity of the washing water increases.

[0034] When removing or attaching the residue filter 9 or the detergent tank 16 for cleaning, if the placement portion 23 is located above the residue filter 9 or the detergent tank 16, it is difficult to remove or attach the residue filter 9 or the detergent tank 16.

[0035] To solve this problem, dishwasher 40 of embodiment 1 includes support part 24 for supporting mounting part 23 with at least opening 3a side raised. This allows the user to support mounting part 23 with opening 3a side raised when attaching or detaching residue filter 9 or detergent tank 16, making it easy to attach or detach residue filter 9 or detergent tank 16.

[0036] FIG. 4 shows the mounting portion 23 supported by the support portion 24. The support portion 24 is provided on the side of the cleaning tank 2 facing the opening 3a. When a user installs or removes the residue filter 9 or the detergent tank 16, the user lifts the opening 3a side of the mounting portion 23 upward and hooks the upper end of the rear side of the mounting portion 23 under the support portion 24, thereby supporting the mounting portion 23 with the opening 3a side of the mounting portion 23 raised. When returning the mounting portion 23, the user slightly lifts the opening 3a side of the mounting portion 23 to remove the upper end of the rear side of the mounting portion 23 from the support portion 24, and then places the mounting portion 23 on the bottom of the cleaning tank 2. This allows for easy access to the residue filter 9 and the detergent tank 16 with a simple configuration. The support portion 24 may be provided on a water conduit 25 provided on the back of the cleaning tank 2 for introducing water into the cleaning tank 2 from a water supply or an external tank. This allows the manufacturing cost of the dishwasher 40 to be reduced.

[0037] FIG. 5 shows another example of the configuration of the support portion 24. In this example, the support portion 24 for hanging the mounting portion 23 is provided on the right or left side of the washing tank 2. FIG. 6 shows the mounting portion 23 supported by the support portion 24. When a user attaches or detaches the residue filter 9 or the detergent tank 16, the user lifts the entire mounting portion 23 upward and hangs a portion of the mounting portion 23, which is configured to be hangable on the support portion 24, on the support portion 24. When returning the mounting portion 23, the user lifts the entire mounting portion 23 slightly to remove it from the support portion 24, and then places the mounting portion 23 on the bottom of the washing tank 2. This simple configuration allows for easy access to the residue filter 9 and the detergent tank 16.

[0038] FIG. 7 shows another example of the configuration of the support portion 24. FIG. 7 shows a state in which the mounting portion 23 is supported by the support portion 24. In the example shown in this figure, the support portion 24 is provided to hook the opening 3a side of the mounting portion 23 onto a higher member. The member on which the support portion 24 is provided may be another mounting portion 23 above, or the top surface of the cleaning tank 2. When returning the mounting portion 23, the opening 3a side of the mounting portion 23 is slightly lifted to remove the mounting portion 23 from the support portion 24, and the mounting portion 23 is then placed on the bottom of the cleaning tank 2. This simple configuration allows for easy access to the residue filter 9 and the detergent tank 16.
