[0001] The present disclosure relates to a dishwasher that washes dishes and the like stored in a washing tub. [Background technology]

[0002] 2. Description of the Related Art In recent years, dishwashers that automatically wash dishes and the like placed in a washing tub provided in a main body have come into use. For example, Patent Document 1 discloses a dishwasher in which an additive device for supplying additives is arranged in an inner door, which is useful for opening and closing the interior of the dishwasher and has a peripheral edge facing the interior when the door is closed, approximately in the center between the side edges and in an upper region between the upper edge and the lower edge. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Special Publication No. 2009-520537 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the above-mentioned conventional dishwashing machines have the following problems. That is, in the dishwasher disclosed in the above publication, the addition device for supplying additives such as rinse aid has a receiving section that is closed via a sliding cover, and the additives are filled into the receiving section with the sliding cover open. For this reason, if a user closes the inner door without closing the sliding cover, the dishwashing operation will be performed with the sliding cover open, and the washing water and the contamination of the dishes stirred up by the nozzle spray may enter the receiving section of the additive device. Since the washing water and the contamination that has entered the receiving section are difficult for the user to remove, additives may not be properly dispensed into the washing tank even after the next operation, which may cause problems with the drying performance.

[0005] The object of the present disclosure is to provide a dishwasher that can effectively prevent contamination of the inside of the detergent supply section that supplies detergent or rinse agent when a cleaning operation is performed with the opening that supplies detergent or rinse agent in an open state. [Means for solving the problem]

[0006] The dishwasher according to the present disclosure includes a washing tank, an opening / closing door, and a detergent supply unit. The washing tank stores dishes. The opening / closing door has a rotating shaft disposed at the lower end thereof, and is opened and closed about the rotating shaft so as to expose the washing tank to an external space. The detergent supply unit has an opening for refilling detergent or rinse agent, an inlet for feeding detergent or rinse agent into the washing tank, and a lid for closing the opening, on the side of the opening / closing door facing the washing tank, and supplies detergent or rinse agent to the washing tank. When the lid is not closing the opening, the opening / closing door cannot be closed and / or operation cannot be started. Effect of the Invention

[0007] According to the dishwasher of the present disclosure, the cleaning operation is performed with the opening for supplying detergent or rinse agent in an open state, which effectively prevents the inside of the detergent supply section for supplying detergent or rinse agent from becoming contaminated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, the embodiments will be described in detail with reference to the drawings as appropriate. However, more detailed explanation than necessary may be omitted. For example, detailed explanation of already well-known matters or duplicate explanation of substantially the same configuration may be omitted. This is to avoid the following explanation becoming unnecessarily redundant and to facilitate understanding by those skilled in the art. The applicant provides the accompanying drawings and the following description so that those skilled in the art can fully understand the present disclosure, and they are not intended to limit the subject matter described in the claims.

[0010] (Embodiment 1) A dishwasher 1 according to one embodiment of the present disclosure will be described below with reference to Figs. 1 to 12. The dishwasher 1 according to this embodiment is a built-in type dishwasher that is incorporated into, for example, a system kitchen and washes dishes (not shown) as objects to be washed in an internal washing tub 3. The dishwasher 1 also supplies detergent and rinse agent (described later) into the washing tub 3 and performs a washing process, a rinsing process, a drying process, and the like.

[0011] In addition, the tableware washed by the dishwasher 1 includes, for example, containers used for eating (plates, bowls, etc.), cutlery (chopsticks, spoons, forks, knives, etc.), and cooking utensils used for cooking, such as knives, cutting boards, frying pans, pots, etc. (1) Configuration of Dishwasher 1 As shown in Figures 1 and 2, the dishwasher 1 comprises a housing 2, a washing tub 3 provided inside the housing 2 for containing tableware (items to be washed), and a pivotable opening / closing door 4 for opening and closing an opening 5 located on the front side of the washing tub 3.

[0012] 1 and 2, in this embodiment, the front direction will be described as the direction in which the dish basket (internal part) 9 is pulled out of the washing tub 3, or the direction toward the opening 5, and the rear direction will be described as the direction in which the dish basket 9 is stored in the washing tub 3, or the direction toward the rear surface 2d. In the following description, the top surface 2b side of the washing tub 3 of the dishwasher will be referred to as the top, the bottom surface 2c side as the bottom, and further, the right side as viewed from the front of the opening / closing door 4 will be referred to as the right side and the left side as the left side.

[0013] As shown in Figs. 1 and 2, the housing 2 is a box-shaped member having a substantially rectangular parallelepiped shape, and is provided therein with a washing tank 3 in which tableware is placed, a tableware basket 9, and the like. 1 and 2, washing tub 3 is provided inside housing 2 for washing tableware set in dish basket 9, and has an opening 5 on the front. Washing tub 3 is also provided with dish basket 9 for storing tableware, a rotating washing nozzle 10, a top washing nozzle 11, a middle washing nozzle 19, etc.

[0014] 1 and 2, the opening / closing door 4 has a handle 41, a flat portion 42 provided on the front surface, a display operation portion 43, and a display portion 44. The opening / closing door 4 rotates about a rotation axis 4a (see FIG. 5, etc.) to open and close the opening 5 relative to the housing 2 so as to cover the opening 5. Moreover, the open / close state of the door 4 is detected by a door open / close switch 18 (see FIG. 4).

[0015] The handle 41 is a groove portion that is gripped by a user when opening and closing the opening and closing door 4 relative to the housing 2, and is provided above the flat portion . The flat surface portion 42 is covered with a surface material, etc. On the top surface of the opening and closing door 4, a display operation portion 43, a display portion 44, etc. are arranged. The display operation unit 43 receives operation inputs from the user, and inputs such as the washing course of the dishwasher 1 and power on / off are performed.

[0016] Display unit 44 displays information such as the status of washing and drying by dishwasher 1, the operating status, time, settings input to display operation unit 43, and the like. Opening 5 is opened and closed by opening / closing door 4 which is rotatably attached to housing 2. When opening 5 is open, dish basket 9 is placed in washing tub 3 so as to be removable in the front-rear direction, as shown in FIG.

[0017] Tableware to be washed or that has already been washed is placed in the dish basket 9. To take the dish basket 9 in or out, a user opens the door 4 and then holds the handle 9a and pulls it forward, as shown in FIG. In Figures 1 to 3, the dish baskets 9 are shown as having three tiers, with an upper tier, a middle tier, and a lower tier, but it may also be configured with two tiers, an upper tier and a lower tier, or with four or more tiers.

[0018] Furthermore, the dishwasher 1 is equipped with a water supply section (not shown) that supplies water to the washing tub 3, a washing pump 13a (see Figure 4), a water supply path 12 from the washing pump 13a to the top washing nozzle 11, a water supply path from the washing pump 13a to the middle washing nozzle 19, a washing path (not shown) from the washing pump 13a to the rotating washing nozzle 10, and a water distribution mechanism including a water distribution motor 15a (see Figure 4) that distributes washing water to the washing path to the rotating washing nozzle 10 and the water supply path 12 to the top washing nozzle 11.

[0019] The water supply unit includes a water supply hose (not shown), a water supply valve 16a (see FIG. 4), etc. Specifically, first, the control device 20 shown in FIG. 4 controls the water supply valve 16a to supply cleaning water such as tap water from, for example, a branch water faucet in a system kitchen to a water supply path such as a water supply hose. The supplied cleaning water is supplied to the cleaning tank 3 through the water supply path in the amount required. At this time, the cleaning water supplied into the cleaning tank 3 may be heated by a cleaning heater 14 (see FIG. 4) and circulated in the form of hot water.

[0020] The washing pump 13a pressure-feeds washing water to the rotary washing nozzle 10 and the top surface washing nozzle 11. When multiple rotary washing nozzles 10 are provided, the washing water is pressure-feed from the washing pump 13a to each rotary washing nozzle 10 and / or top surface washing nozzle 11 via a water distribution mechanism including a water distribution motor 15a. The rotating cleaning nozzle 10 is installed, for example, below the dish basket 9, as shown in Figure 3, and rotates due to the reaction force of the pressurized cleaning water, spraying cleaning water from below toward the dishes placed in the dish basket 9.

[0021] In addition, the rotating cleaning nozzle 10 may be a type of nozzle that sprays cleaning water toward the tableware from a cleaning hole provided in a cleaning path (not shown) provided on a side surface (side surface 2a other than the top surface) inside the cleaning tank 3. 3, the top washing nozzle 11 is installed above the dish basket 9, that is, on the ceiling surface of the washing tub 3. Like the rotating washing nozzle 10, the top washing nozzle 11 sprays washing water from above toward the dishes placed in the dish basket 9 while rotating due to the reaction force of the pressurized washing water.

[0022] The middle-level washing nozzle 19 is installed on the bottom surface of the middle-level dish basket 9, for example, as shown in Fig. 2. Like the rotating washing nozzle 10, the middle-level washing nozzle 19 rotates due to the reaction force of the pressurized washing water and sprays washing water from below toward the tableware placed in the middle-level dish basket 9 and from above toward the tableware placed in the lower-level dish basket 9. That is, the washing pump 13a pressurizes the washing water stored in the washing tank 3 and supplies it to the rotating washing nozzle 10, the top washing nozzle 11, and the middle washing nozzle 19. The washing water sprayed from the rotating washing nozzle 10 and the top washing nozzle 11 removes dirt adhering to the tableware and washes the tableware. The washing water includes a washing liquid containing detergent that is sprayed onto the objects to be washed, and a rinsing liquid containing a rinse agent R1 that is added when rinsing the objects to be washed.

[0023] Furthermore, the suction side of the washing pump 13a is connected to the drain outlet 7, and the washing water supplied into the washing tank 3 is circulated through the washing path and the water supply path 12, and the washing water is sprayed from the rotating washing nozzle 10 and the top surface washing nozzle 11. Then, the dishes are washed with the sprayed washing water. As shown in FIG. 3, the drain outlet 7 is provided at the bottom of the cleaning tank 3.

[0024] A residue filter (not shown) is detachably provided at drain outlet 7 and collects residue washed and removed from the object to be washed. Drain pump 13b (see FIG. 4) drains the washing water from within washing tank 3 after the washing process is completed. In the cleaning process, the cleaning heater 14 (see FIG. 4) heats the cleaning water stored in the cleaning tank 3. The cleaning heater 14 is disposed near the bottom of the cleaning tank 3. Note that the cleaning heater 14 may not be disposed near the bottom of the cleaning tank 3, but may be built into the cleaning pump 13a.

[0025] The washing pump 13a may also function as a drainage pump by reversing the rotation direction of the motor during circulation, to discharge the washing water from the washing tank 3. In this case, by making the washing pump 13a also function as a drainage pump, the drainage pump can be made unnecessary. Also, a drain valve may be provided instead of the drain pump 13b. In this case, the cleaning water can be drained from the cleaning tank 3 by natural fall due to gravity when the drain valve is opened.

[0026] Here, the dishwasher 1 is provided with a drainage path (not shown) for draining wash water from the washing tub 3. The drainage path is configured to include a drain outlet 7, a drain pump 13b, a drain hose (not shown), and the like. When the dish washing and rinsing processes are completed, the drain pump 13b is driven, and the wash water passes through the drain outlet 7 and is then drained to the outside via the drain hose.

[0027] Furthermore, the dishwasher 1 of this embodiment dries the washed dishes. That is, as shown in FIG. 4, the dishwasher 1 of this embodiment is provided with a blower fan 17a and a blower heater 17b. The blower fan 17a and the blower heater 17b are installed in a drying air duct that communicates with an air supply port located at the bottom of the side wall of the washing tank 3, and take in air from an air intake port (not shown) and supply it into the washing tank 3 to dry the washed tableware.

[0028] That is, when the blower fan 17a is driven, the tubular blower heater 17b is also driven, so that air taken in from the air inlet and heated in the drying air duct is blown onto the tableware in the washing tub 3. A first exhaust port (not shown) is provided at the top of the side wall of the washing tank 3, and an exhaust path is installed outside the side surface 2a of the washing tank 3. The air supplied into the washing tank 3 from the air supply port contains moisture from within the washing tank 3, passes through the exhaust path from the first exhaust port, and is exhausted to the outside of the machine from a second exhaust port (not shown). In this way, the blowing of heated air and the exhaust of humid air can promote drying of the tableware in the washing tank 3.

[0029] In the dishwasher 1 of this embodiment, the control device 20 controls each part provided inside the housing 2, as shown in FIG. 4, the control device 20 includes an I / F (interface) 20a, a processor 21, and a memory 22, and is provided below the cleaning tank 3 as a control board. In the control device 20, the processor 21 reads a control program 22a stored in the memory 22 and executes a cleaning operation and a drying operation.

[0030] More specifically, the control device 20 carries out a washing process for washing the tableware, a rinsing process for rinsing the detergent and residue adhering to the tableware, and a drying process for drying the washed tableware. During the washing and rinsing processes, the control device 20 controls the washing pump 13a, washing heater 14, drain pump 13b, water distribution motor 15a, residual water motor 15b, water supply valve 16a, flow meter 16b, etc. shown in Figure 4 to wash the dishes in the washing tank 3.

[0031] In addition, in the drying step, the control device 20 controls the blower fan 17a and the blower heater 17b shown in FIG. 4 to dry the washed tableware. The processor 21 is, for example, a CPU (Central Processing Unit) or an MPC (Micro Processing Unit), etc. The processor 21 reads out and executes a control program 22a stored in the memory 22, thereby functioning as an operation control unit 21a, a display operation control unit 21b, a maintenance unit 21c, and an input control unit 21d.

[0032] The operation control unit 21a controls various devices connected to the control device 20 to control the washing operation of the dishwasher 1. The washing operation controlled by the operation control unit 21a may be an operation in which a washing process, a rinsing process, a drying process, and a storage process are performed consecutively in this order, or an operation in which only any one of the processes is performed, or an operation in which two or more of the processes are performed in any order.

[0033] Here, the storage step is a step of storing tableware in the washing tank 3 when the opening / closing door 4 is in a closed state. The storage step includes at least one of a dry storage step and a sterilization storage step. The dry storage step is a step of drying and storing the tableware by the blower fan 17a. The sterilization storage step is a step of sending charged fine particle water or ions generated by an electrostatic atomization device (not shown) into the washing tank 3 to sterilize and store the tableware.

[0034] The operation control unit 21a can execute water-saving and energy-saving operation during the washing operation. The water-saving and energy-saving operation is an operation for saving water and energy during the washing operation. A washing operation accompanied by the water-saving and energy-saving operation can save water and reduce the amount of power consumption more than a washing operation without the water-saving and energy-saving operation. The operation control unit 21a judges whether or not to execute the water-saving and energy-saving operation during the washing operation based on the temperature change per unit time detected by the water temperature detection unit 37 and the detection signal of the turbidity detection sensor (not shown). Then, when the operation control unit 21a judges to execute the water-saving and energy-saving operation, it executes the water-saving and energy-saving operation during the washing operation.

[0035] The display operation control unit 21b causes various pieces of information to be displayed on the display operation unit 43. In addition, the display operation control unit 21b accepts various operations from the user via the display operation unit 43. The maintenance unit 21c performs a maintenance operation to clean the detergent supply passage, which supplies the liquid or solid detergent stored in the detergent supply unit 39 into the cleaning tub 3, with the liquid stored in the detergent supply unit 39.

[0036] In the maintenance operation, the liquid stored in detergent supply unit 39 is, for example, water with citric acid dissolved therein at 40° C. Note that the liquid stored in detergent supply unit 39 may be water with citric acid dissolved therein at 40° C. or less, water with citric acid dissolved therein at 40° C. or more, water without citric acid dissolved therein, or water with a component other than citric acid dissolved therein.

[0037] For example, during the rinsing process, when the temperature of the cleaning water detected by the water temperature detection unit 37 reaches a predetermined temperature (e.g., 40°C), the input control unit 21d controls the solenoid valve (input valve) 36a of the rinse agent supply unit 30 to input rinse agent R1 from the input tank 36 (see Figure 8) in the rinse agent supply unit 30 into the cleaning tank 3. The supply control unit 21d may adjust the supply amount of the rinsing agent R1 supplied to the cleaning tank 3 by controlling the number of times and the time for which the solenoid valve 36a is opened and closed.

[0038] The memory 22 is a storage device that stores programs, various data, and the like, and stores the control program 22a and various data processed by the processor 21. The memory 22 has a non-volatile storage area. Note that the memory 22 may have a volatile storage area and constitute a work area for the processor 21. The I / F 20a has communication hardware that complies with a predetermined communication standard, such as a connector, a communication circuit, etc. As shown in Fig. 4, the I / F 20a is connected to the wash pump 13a, the drain pump 13b, the wash heater 14, the water distribution motor 15a, the remaining water motor 15b, the water supply valve 16a, the flow meter 16b, the blower fan 17a, the blower heater 17b, the cooling fan 17c, the door opening / closing switch 18, the display operation unit 43, the solenoid valve 36a, the water temperature detection unit 37, and the rinse agent remaining amount detection unit 38, and communicates with these devices.

[0039] (2) Configuration of Rinse Agent Supply Unit 30 The dishwasher 1 of this embodiment is provided with a rinse agent supply section (detergent supply section) 30 that supplies rinse agent R1 (see FIG. 8) to the washing tub 3, as shown in FIG. The rinse aid R1 is composed of a component different from the detergent supplied from the detergent supply unit 39 into the washing tank 3, and contains, for example, a dissolved hydrophilic component that is supplied when the pH of the washing water drops during the rinsing process. By adding the rinse aid R1 to the washing water, it is possible to improve the drainage of the surface of the tableware, improve the drying efficiency, and reduce power consumption during the drying process.

[0040] 5, the rinse agent supply unit 30 is provided adjacent to the detergent supply unit 39 in the same housing as the detergent supply unit 39, which supplies the detergent used in the cleaning process into the cleaning tank 3. The rinse agent supply unit 30, together with the detergent supply unit 39, is provided in a substantially central portion of the inner surface 4b on the cleaning tank 3 side of the opening / closing door 4. As shown in FIGS. 6A and 6B, the rinse agent supply unit 30 has an opening 31a for refilling the rinse agent R1, an input port 31b for inputting an amount of rinse agent R1a (see FIG. 8) for one cleaning into the cleaning tank 3, and a lid 32 for closing the opening 31a.

[0041] The opening 31a is an opening for refilling the rinse agent R1 stored in a storage tank 35 (see FIG. 8) provided inside the rinse agent supply unit 30, and is in communication with the storage tank 35. The opening 31a is closed when the lid 32 is closed (see FIG. 6A), and is open when the lid 32 is rotated towards the cleaning tank 3 and opened (see FIG. 6B). That is, when refilling the storage tank with the rinse agent R1, the lid 32 is opened to open the opening 31a, and the rinse agent R1 is refilled into the storage tank through the opening 31a.

[0042] On the other hand, in the above-mentioned cleaning process, rinsing process, drying process, etc., the opening 31a is closed by the lid 32. This makes it possible to prevent cleaning water, contaminants, etc. from entering the inside of the rinse agent supply part 30 (the supply path of the rinse agent R1, the storage tank 35, the input tank 36, etc.) through the opening 31a during the cleaning process, etc. As shown in FIG. 7, the opening 31a is provided above the rinse agent supplying part 30 when the opening / closing door 4 is closed.

[0043] As shown in FIG. 7, when the opening / closing door 4 is closed, the supply port 31b is provided below the opening 31a in the rinse agent supply part 30, and supplies one dose of rinse agent R1a (see FIG. 8) into the cleaning tank 3. Here, one dose of rinse agent R1a refers to the rinse agent stored in the input tank 36 from the storage tank 35 shown in FIG. 8 when the opening and closing door 4 is opened and closed once.

[0044] That is, when the opening / closing door 4 is opened from a closed state, the upper side in Fig. 8 faces diagonally downward, and a predetermined amount of rinse agent R1a moves from the storage tank 35 to the input tank 36 in the rinse agent supplying part 30. When the opening / closing door 4 is closed from an open state, the up-down relationship shown in Fig. 8 is restored, and a predetermined amount of rinse agent R1a is held in the input tank 36 in the rinse agent supplying part 30.

[0045] The amount of rinse agent R1 stored in the input tank 36 may be more than the amount required for one cleaning. In this case, the input control unit 21d described above controls the number of times and the time for which the solenoid valve 36a is opened and closed, thereby adjusting the input amount of rinse agent R1 input to the cleaning tank 3. At this time, the input tank 36 is sealed by a seal part 36b that is opened and closed via a solenoid valve 36a. Then, for example, when the above-mentioned water temperature detection part 37 detects that the temperature of the wash water has reached a predetermined temperature (for example, 40°C), the input control part 21d of the control device 20 controls the solenoid valve 36a to release the sealed state by the seal part 36b.

[0046] As a result, the amount of rinse agent R1a stored in the input tank 36 for one use moves by gravity along the direction of the arrow shown in FIG. 8 to the communication part 36c that communicates with the input port 31b. As a result, one dose of rinse agent R1a is supplied by gravity from the gap d1 near the lower end of the lid 32 through the inlet 31b. 8, the amount of rinse agent R1 stored in the storage tank 35 is detected by a rinse agent remaining amount detection unit 38 using a float member 38a floating on the rinse agent R1. As a result, when the amount of rinse agent R1 stored in the storage tank 35 decreases, a warning is displayed on the display unit 44 or the like to inform the user that rinse agent R1 has run out, and the user is prompted to refill the rinse agent R1.

[0047] As described above, the lid part 32 can be opened and closed relative to the opening 31a provided in the main body of the rinse agent supplying part 30, and is provided in a state where it can rotate about the rotation shaft 33 provided on both side surfaces at the lower end part as shown in Fig. 9. The lid part 32 has a plate-shaped main body part 32a, an elastic ring 32b, a locked part 32c, and a lower end surface 32d. The plate-shaped main body 32a rotates about a rotation shaft 33, and covers the opening 31a and the insertion port 31b when the lid 32 is closed.

[0048] The elastic ring 32b is provided on the side facing the opening 31a near the end of the main body 32a opposite to the rotating shaft 33, and elastically deforms in contact with the outer periphery of the opening 31a when the lid 32 is closed. As a result, the opening 31a is closed from the cleaning tank 3 side when the lid 32 is closed. The locked portion 32c is provided at the end of the main body 32a opposite the rotation shaft 33, and is locked to a locking portion 31c provided above the opening 31a.

[0049] This allows the upper end of the main body portion 32a to be held so that the lid portion 32 does not open when the lid portion 32 is closed. Lower end surface 32d is an end surface that is located at the lower end of main body portion 32a when lid portion 32 is closed, and is disposed in the vicinity of rotation shaft 33. When lid portion 32 is opened, lower end surface 32d abuts against abutment surface 34a of rib 34, which will be described later, thereby determining the opening angle (maximum rotation range) of lid portion 32.

[0050] 10A and 10B, the rib 34 is disposed near the lower end of the main body of the rinse agent supplying part 30, in the vicinity of the rotation shaft 33. The rib 34 comes into contact with the lower end surface 32d of the main body part 32a of the lid part 32 when the lid part 32 is in the fully open state shown in FIG. This allows the maximum rotation range of cover part 32 when opened to be regulated so that cover part 32 faces diagonally downward as shown in FIG. 10B.

[0051] Therefore, if one attempts to close the opening and closing door 4 while the lid portion 32 is left open, the tip of the open lid portion 32 will interfere with the handle 9a of the dish basket 9 placed in the washing tub 3, as shown in Figure 11. Therefore, even if a user mistakenly closes the door 4 with the lid 32 of the rinse agent dispenser 30 open and attempts to perform a dishwashing operation, the door 4 cannot be completely closed as shown in Fig. 12. This allows the user to realize that he or she has forgotten to close the lid 32 of the rinse agent dispenser 30 and close the lid 32.

[0052] 12, the door 4 is not closed, which is detected by the door switch 18. Therefore, the operation control section 21a of the control device 20 performs control not to permit the start of operation, so that the operation is started with the lid section 32 open, and it is possible to prevent cleaning water and contaminants from entering the inside of the rinse agent supplying section 30.

[0053] Such control not to permit operation may be combined with control to display on the display unit 44 that the opening and closing door 4 is not closed, or control to notify the user by issuing an alarm. <Main features> The dishwasher 1 of this embodiment includes a washing tank 3, an opening / closing door 4, and a rinse agent supply unit 30. The washing tank 3 stores dishes. The opening / closing door 4 has a rotating shaft 4a arranged at the lower end side, and is opened and closed about the rotating shaft 4a so as to expose the washing tank 3 to the outside space. The rinse agent supply unit 30 has an opening 31a for refilling rinse agent R1, an inlet 31b for feeding rinse agent R1 into the washing tank 3, and a lid 32 for closing the opening 31a, on the side of the opening / closing door 4 facing the washing tank 3, and supplies rinse agent R1 to the washing tank 3. When the lid 32 does not close the opening 31a, the dishwasher 1 cannot close the opening / closing door 4 as shown in Figs. 11 and 12, and is in a state in which operation cannot be started.

[0054] As a result, when the lid portion 32 covering the opening 31a for refilling the rinse agent supply section 30 with rinse agent R1 is open, as the opening / closing door 4 is closed, the lid portion 32 comes into contact with the dish basket 9 (handle 9a) provided on the washing tub 3 side, and the opening / closing door 4 cannot be closed. As a result, the cleaning operation is performed with the opening 31a for supplying the rinse agent R1 in an open state, and contamination of the inside of the storage tank 35 and the input tank 36 for storing the rinse agent R1 can be effectively prevented.

[0055] In addition, since the path separating the inlet 31b of the rinse agent R1 into the cleaning tank 3 is relatively short, it is possible to eliminate the risk of damage to the rinse agent supply part 30 due to clogging caused by contamination when the cleaning process is performed with the lid part 32 open. (Embodiment 2) A dishwasher 101 according to another embodiment of the present disclosure will be described below with reference to Figs. 13 to 16.

[0056] The dishwasher 101 of this embodiment differs from the above-described embodiment 1 in that it is provided with a lid portion 132 that is opened and closed by a sliding operation along a groove portion 133, rather than by a rotational operation about a pivot axis as described in the above-described embodiment 1. Since the configuration is substantially the same as that described in the first embodiment except for the configuration related to the lid portion 132, the same reference numerals are used for the overlapping members and detailed description thereof will be omitted.

[0057] As shown in FIG. 13, the dishwasher 101 of this embodiment is equipped with a rinse agent supplying section 130 having a lid section 132 that opens and closes the opening 31a by sliding up and down in the figure when the opening and closing door 4 is in a closed position. 14, the rinse agent supply unit 130 is disposed adjacent to the detergent supply unit 39, similar to the rinse agent supply unit 30 described in the first embodiment. The rinse agent supply unit 130 includes a lid 132 that covers the front surface of the opening 31a to which the rinse agent R1 is replenished.

[0058] 14, when the lid part 132 is in the fully open state, the opening 31a and the supply port 31b are exposed to the front. The lid part 132 can be slid vertically along a groove part 133 provided on the main body side of the rinse agent supply part 130 to close the lid part 132 and cover the opening 31a and the supply port 31b. At this time, the cover 132 is held in the closed state by a latched portion 132c provided on the upper end portion of the cover 132 being latched with a latch portion 131c provided on the main body side of the rinse agent supplying unit .

[0059] Groove portions 133 that guide lid portion 132 in the sliding direction (vertical direction) are provided along the vertical direction on both the left and right sides of opening 31a and inlet 31b on the main body side of rinse agent supplying portion 130. This allows lid portion 132 to slide in the vertical direction. Here, when the cover 132 is opened when refilling the rinse agent supplying part 130 with the rinse agent R1, the cover 132 protrudes downward from the rinse agent supplying part 130 as shown in FIG.

[0060] Therefore, if one attempts to close the opening and closing door 4 with the lid portion 132 left open, the tip of the open lid portion 132 will interfere with the handle 9a of the dish basket 9 placed in the washing tub 3, as shown in Figure 15. Therefore, even if a user mistakenly closes the door 4 while leaving the lid 132 of the rinse agent dispenser 130 open and attempts to perform a dishwashing operation, the door 4 cannot be closed as shown in Fig. 16. This allows the user to realize that he or she has forgotten to close the lid 132 of the rinse agent dispenser 130 and to close the lid 132.

[0061] 16, the door switch 18 detects that the door 4 is not closed, and the operation control section 21a of the control device 20 performs control not to permit the start of operation. This prevents the operation from being started with the lid 132 open, and prevents cleaning water and contaminants from entering the rinse agent supplying section 130.

[0062] Such control not to permit operation may be combined with control to display on the display unit 44 that the opening and closing door 4 is not closed, or control to notify the user by issuing an alarm. Furthermore, as long as lid portion 132 can be moved until it interferes with an internal part such as dish basket 9, it is not necessarily necessary to slide lid portion 132 until opening 31a is in the open state.

[0063] <Main features> The dishwasher 101 of this embodiment includes a washing tank 3, an opening / closing door 4, and a rinse agent supply unit 130. The washing tank 3 stores dishes. The opening / closing door 4 has a rotating shaft 4a arranged at the lower end side, and is opened and closed about the rotating shaft 4a so as to expose the washing tank 3 to the outside space. The rinse agent supply unit 130 has an opening 31a for refilling rinse agent R1, an input port 31b for inputting rinse agent R1 into the washing tank 3, and a lid unit 132 for closing the opening 31a, on the side of the opening / closing door 4 facing the washing tank 3, and supplies rinse agent R1 to the washing tank 3. When the lid unit 132 does not close the opening 31a, the dishwasher 101 cannot close the opening / closing door 4 as shown in Figs. 15 and 16, and is in a state in which operation cannot be started.

[0064] As a result, when the lid portion 132 covering the opening 31a for refilling the rinse agent supply portion 130 with rinse agent R1 is open, as the opening / closing door 4 is closed, the lid portion 132 comes into contact with the dish basket 9 (handle 9a) provided on the washing tub 3 side, and the opening / closing door 4 cannot be closed. As a result, the cleaning operation is performed with the opening 31a for supplying the rinse agent R1 in an open state, and contamination of the inside of the storage tank 35 and the input tank 36 for storing the rinse agent R1 can be effectively prevented.

[0065] (Embodiment 3) A dishwasher 201 according to still another embodiment of the present disclosure will be described below with reference to Figs. 17 to 19. The dishwasher 201 of this embodiment differs from the above-mentioned embodiments 1 and 2 in that, instead of mechanically creating a state in which operation cannot be started by closing the opening / closing door 4 while the lid part 32, 132 is open as described in embodiments 1 and 2, as the opening / closing door 4 interferes with internal parts such as the dish basket 9 and prevents the opening / closing door 4 from being closed, when the lid opening / closing detection unit 239 shown in Figure 19 electrically detects the open state of the lid part 32, 132, the operation control unit 21a controls the operation to be unable to be started.

[0066] Since the configuration is substantially the same as that described in the above embodiment 1 except for the configuration related to the cover open / close detector 239, the same reference numerals are used for the overlapping members and detailed description will be omitted. In this embodiment, as in the first and second embodiments, the pivotable lid 32 is described as an example, but the present invention can also be applied to a sliding lid 132 as in the second embodiment.

[0067] As shown in FIG. 17, the dishwasher 201 of this embodiment is equipped with a rinse agent supplying section (detergent supplying section) 230 having a lid section 32 that rotates around a pivot shaft 33 to open and close the opening 31a, similar to the rinse agent supplying section 30 described in the first embodiment above. As shown in FIG. 17, the rinse agent supplying section 230 has a reed switch 239a and a magnet 239b.

[0068] The reed switch 239a and the magnet 239b constitute a cover opening / closing detector 239 shown in FIG. The reed switch 239a is provided on the upper end portion of the rinse agent supplying part 230 on the main body side, on a surface that faces the vicinity of the upper end portion of the lid part 32 when the lid part 32 is closed. The reed switch 239a detects a magnetic field that changes depending on whether or not a magnet 239b is present nearby when the lid part 32 is opened or closed.

[0069] Magnet 239b is provided on the end of main body 32a of lid 32 opposite rotation shaft 33, on the surface facing opening 31a. As a result, the lid opening / closing detection unit 239 can easily detect whether the lid portion 32 is in the closed state shown in FIG. 18A or the open state shown in FIG. 18B by detecting whether the magnet 239b attached to the lid portion 32 is in the vicinity of the reed switch 239a.

[0070] In the dishwasher 201 of this embodiment, when the lid 32 is open as shown in Fig. 18B, there is no need to define the rotation range of the lid 32 in order to mechanically create a state in which the opening and closing door 4 cannot be closed. Therefore, there is no need for a member equivalent to the rib described in the above embodiment 1. Here, in the dishwasher 201 of this embodiment, as shown in FIG. 19, the open / closed state of the lid part 32 is detected by using a reed switch 239a and a magnet 239b.

[0071] Thereby, the operation control section 21a of the control device 20 receives the detection result from the cover open / close detection section 239, and performs control so as not to permit the start of operation if the cover section 32 is open. As a result, even if the opening and closing door 4 is closed while the lid portion 32 is in the open position, the operation is prevented from starting, and the inside of the storage tank 35 and the input tank 36 which store the rinse agent R1 can be effectively prevented from being contaminated.

[0072] Such control not to permit operation may be combined with control to display on the display unit 44 that the opening and closing door 4 is not closed, or control to notify the user by issuing an alarm. <Main features> The dishwasher of this embodiment includes a washing tank 3, an opening / closing door 4, and a rinse agent supply unit 230. The washing tank 3 stores dishes. The opening / closing door 4 has a rotating shaft 4a arranged at the lower end side, and is opened and closed about the rotating shaft 4a so as to expose the washing tank 3 to the outside space. The rinse agent supply unit 230 has an opening 31a for refilling rinse agent R1, an inlet 31b for feeding rinse agent R1 into the washing tank 3, and a lid unit 32 for closing the opening 31a, on the side of the opening / closing door 4 facing the washing tank 3, and supplies rinse agent R1 to the washing tank 3. In a state in which the lid unit 32 does not close the opening 31a, when the lid opening / closing detection unit 239 shown in FIG. 19 detects that the lid unit 32 is open, the dishwasher 1 is in an operation start disabled state by controlling the operation control unit 21a not to start the washing operation.

[0073] As a result, when the lid portion 32 covering the opening 31a through which the rinse agent supply section 230 is replenished with the rinse agent R1 is open, the open state of the lid portion 32 is detected and control is performed so as not to allow operation to start, thereby effectively preventing contamination of the storage tank 35 and the input tank 36 which store the rinse agent R1 due to the cleaning operation being performed with the opening 31a through which the rinse agent R1 is supplied remaining in the open state.

[0074] [Other embodiments] Although one embodiment of the present disclosure has been described above, the present disclosure is not limited to the above embodiment, and various modifications are possible without departing from the gist of the disclosure. (A) In the above-mentioned first and second embodiments, the rinse agent supply unit 30, 130 that supplies rinse agent R1 attached to the inner surface 4b of the door 4 of the dishwasher 1 is used as the detergent supply unit of the present disclosure. However, the present disclosure is not limited to this.

[0075] For example, the configuration of the cleaning agent supply unit of the present disclosure may be applied to the detergent supply unit in which the detergent is stored, or the configuration of the present disclosure may be applied to both the detergent supply unit and the rinse agent supply unit. Even in this case, as in the above embodiment, the cleaning operation is performed with the opening for supplying detergent in an open state, which effectively prevents contamination of the inside of the tank in which the detergent is stored.

[0076] (B) In the above-mentioned embodiment 1, an example has been described in which the rib 34 is provided on the rinse agent supplying part 30 side to regulate the maximum angle of the cover part 32 relative to the inner surface of the opening and closing door 4 when the cover part 32 included in the rinse agent supplying part 30 is in an open state. However, the present disclosure is not limited to this. For example, a rib that restricts the maximum angle of the lid portion may be provided on the inner surface of the opening and closing door.

[0077] (C) In the above-mentioned first and second embodiments, a configuration has been described in which, when the opening and closing door 4 is closed with the lid 32 open, the opening and closing door 4 interferes with the dish basket 9 installed on the side of the washing tub 3. However, the present disclosure is not limited to this. For example, the object that interferes with the lid when the opening and closing door is attempted with the lid open need not be the dish basket, but may be another internal part.

[0078] (D) In the above-mentioned second embodiment, an example has been described in which the opening 31a is opened and closed by sliding the cover 132 in the vertical direction, but the present disclosure is not limited to this. For example, the cover may be configured to slide left and right or diagonally.

[0079] Even in this case, the same effect as in the above embodiment can be obtained by preventing the opening and closing door from being closed due to interference between the lid portion and the internal components when the lid portion is slid open. (E) In the above-described third embodiment, an example has been described in which the reed switch 239a and the magnet 239b are used as the cover open / close detector 239 that detects the open / closed state of the cover 32, 132 included in the rinse agent supply unit 30. However, the present disclosure is not limited to this.

[0080] For example, as a detector for detecting the opening and closing of the lid, other configurations may be used, such as a contact switch that detects contact with the tip portion of the lid, in addition to the combination of a reed switch and a magnet. (F) In the above embodiment, an example has been described in which the dishwasher 1 performs a washing process for washing tableware set in the washing tub 3 and a drying process for drying the washed tableware. However, the present disclosure is not limited to this.

[0081] For example, the configuration of the present disclosure may be applied to a dishwasher that does not have a drying function and only performs a cleaning process. (G) In the above embodiment, the dishwasher 1 is described as being equipped with a pivotable door 4 for opening and closing the opening 5 located in front of the washing tub 3. However, the present invention is not limited to this.

[0082] For example, it may be a dishwasher with a pull-open door (a type in which the top surface is opened by pulling the front door forward). In this case, the rinse agent supply unit that supplies the rinse agent can be appropriately changed to a suitable position on the inner surface of the opening and closing door. (H) In the above embodiment, a built-in dishwasher installed in a system kitchen or the like has been described as an example. However, the present disclosure is not limited to this.
