Summary of the Invention

Problems to be Solved by the Invention

[0004] In a conventional washing machine, water in the washing chamber is prevented from leaking to the outside (such as a machine room) by the extended portion of the door portion entering the housing portion of the main body portion. In such a configuration, a gap may be formed between the extended portion and the housing portion, so there is a risk that water in the washing chamber may leak out. Therefore, in the washing machine, a sealing portion (packing) is arranged between the main body portion and the door portion to suppress water leakage. The sealing portion is deformed by being sandwiched between the door portion and the main body portion when the door portion is closed, and by being deformed, it adheres closely to the door portion and the main body portion to fill the gap between the door portion and the main body portion.

[0005] In this configuration, the watertightness provided by the seal depends on the tightness of the seal. While dimensional accuracy of the main body, door, and seal is crucial for ensuring tightness, achieving high dimensional accuracy in all parts is difficult. Therefore, it may not always be possible to ensure high tightness throughout the entire seal. Consequently, there may be areas in the seal with poor tightness. In this case, water leaking from these areas may flow down the seal to its lower end, potentially dripping into the machine room or other areas.

[0006] The present invention aims to provide a washing machine that can prevent water dripping from the sealing portion from flowing out of the washing chamber. [Means for solving the problem]

[0007] The washing machine according to the present invention comprises a main body having an opening that opens forward for loading and unloading objects to be washed into a washing chamber, a door that allows the opening to be opened and closed by a pivot shaft rotatably supported at the lower part of the opening, and a sealing part provided on the periphery of the opening in the main body and interposed between the main body and the door when the door is closed. The main body has a water receiving section that extends in the left-right direction below the opening and communicates with the washing chamber, and the water receiving section has a receiving opening that opens upward. The sealing section has an edge portion that is positioned on the side edge of the opening and extends in the vertical direction, the lower end of the edge portion has an upper end and a lower end, the lower end is located closer to the opening than the upper end when viewed from the front side of the main body, and is inclined downward from the upper end to the lower end, the upper end of the lower end is located above the receiving opening, and the lower end of the lower end is located inside the water receiving section below the receiving opening.

[0008] In the washing machine according to the present invention, the lower end of the edge portion of the sealing part has an upper end and a lower end, and when viewed from the front side of the main body, the lower end is located closer to the opening than the upper end, and is inclined downward from the upper end to the lower end. The upper end of the lower end of the edge portion is located above the receiving opening, and the lower end of the lower end is located below the receiving opening within the water receiving section. As a result, in the washing machine, if water leaks from a point in the sealing part with poor airtightness and flows down the edge portion to the lower end, the water flows down the inclination from the upper end to the lower end and drips (discharges) from the lower end into the water receiving section. Since the water receiving section is in communication with the washing chamber, the water discharged into the water receiving section is discharged into the washing chamber. Therefore, the washing machine can prevent water dripping from the sealing part from flowing out of the washing chamber.

[0009] In the washing machine according to the present invention, the main body is provided with a recess into which a sealing portion is fitted, and the door may be provided with a protrusion that projects toward the main body at a position facing the recess when the door is closed. In this configuration, when the door is closed, the protrusion of the door presses against the sealing portion. Therefore, the airtightness between the main body and the door can be improved. [Effects of the Invention]

[0010] According to the present invention, it is possible to suppress the outflow of water dripping from the sealing portion to the outside of the washing chamber. [Brief explanation of the drawing]

The machine room 1A forms a space that extends in the front-to-back and left-to-right directions when viewed from the vertical. The upper region of the main body 1 contains a washing chamber 1B that houses a rack on which dishes (items to be washed) D are set. The washing chamber 1B is the space above the washing water tank 20 and is composed of interior panels 2. The interior panels 2 mainly consist of a pair of side panels 2A, 2A, an upper panel 2B, and a rear panel (not shown). Rack rails 23 that support the rack are formed on the inner surfaces of the pair of side panels 2A, 2A. The main body 1 has an opening 1C for loading and unloading the rack on which dishes D are set into the washing chamber 1B. The rack rail 23 may be formed integrally with the side panels 2A, 2A by drawing, or it may be formed by attaching other members to the inner surfaces of the side panels 2A, 2A.

[0017] The main body 1 is provided with a water receiving section 1D (see Figure 15). The water receiving section 1D is located on the back (rear side) of the lower front panel 11D. The water receiving section 1D receives water dripping from the sealing section 80, etc., which will be described later, and discharges the water into the washing chamber 1B. The water receiving section 1D is provided extending in the left-right direction below the opening 1C. As shown in Figures 15 and 16, the water receiving section 1D is composed of a front section 110, a pair of side sections 111 (the right side section is not shown), and a part of the guide section 21 (described later). Figures 15 and 16 show a magnified view of a part of the state in Figure 13 with the lower front panel 11D removed.

[0018] The front portion 110 and the pair of side portions 111 are plate-shaped members. The front portion 110 and the pair of side portions 111 are formed integrally. The front portion 110 extends in the left-right direction. The side portions 111 are connected to the ends of the front portion 110 and extend in the front-rear direction. The bottom of the water receiving portion 1D is formed by a guide portion 21. Specifically, the bottom of the water receiving portion 1D is formed by the front portion of the guide portion 21 that forms the washing chamber 1B. As a result, the water receiving portion 1D is in communication with the washing chamber 1B. The water receiving portion 1D has a receiving opening 1E that opens upward. The receiving opening 1E is formed by the upper ends of the front portion 110 and the pair of side portions 111.

[0019] As shown in Figure 1, the door section 15 is located outside the opening 1C. The door section 15 is provided so as to be able to open and close the opening 1C, and when the door section 15 is opened, the washing chamber 1B is opened to the outside of the main body 1. The door section 15 is provided so as to be able to rotate around an axis that extends in the left-right direction at the lower end of the door section 15. The operator can open the washing chamber 1B by tilting the handle 15A provided at the upper end of the door section 15 towards them.

[0020] The washing water tank 20 is located below the washing chamber 1B. The washing water tank 20 stores washing water used to wash dishes D and the like housed in the washing chamber 1B. The washing water is the water sprayed into the washing chamber 1B during the washing process. The washing water tank 20 consists of a guide section 21 (see Figure 8) and a storage section 22. The guide section 21 separates the machine room 1A from the washing chamber 1B and is the part that receives the water sprayed from the upper nozzle 3 and the lower nozzle 4, and guides the water that has fallen after washing or rinsing the dishes D, to the storage section 22. The guide section 21 forms the washing chamber 1B. The storage section 22 is the part that stores the washing water supplied to the upper nozzle 3 and the lower nozzle 4 by the washing pump 5. The storage section 22 consists of a bottom section 22A and a side section 22B.

[0021] The storage section 22 of the cleaning water tank 20 is equipped with a cleaning water detection unit 24, a cleaning water heater 25A, and a cleaning water temperature sensor 25B.

[0022] The cleaning water detection unit 24 detects the water level of the cleaning water stored in the cleaning water tank 20. The cleaning water detection unit 24 is a switch that, for example, turns ON when the water level in the cleaning water tank 20 exceeds a constant water level H1, and turns OFF when it is below the constant water level H1. The detection result from the cleaning water detection unit 24 is acquired by the controller 10. The cleaning pump 5, which will be described in detail later, will not be able to spray cleaning water from the upper nozzle 3 and lower nozzle 4 if it sucks in air while in operation, causing what is called air lock. In one embodiment, the operation of the cleaning pump 5 is stopped when the cleaning water detection unit 24 is turned OFF during operation, thereby preventing the cleaning pump 5 from sucking in air.

[0023] The cleaning water heater 25A heats the cleaning water stored in the cleaning water tank 20 to a predetermined temperature in order to improve its sterilization and cleaning capabilities. The cleaning water temperature sensor 25B detects the temperature of the cleaning water stored in the cleaning water tank 20. The detection result from the cleaning water temperature sensor 25B is acquired by the controller 10. The ON / OFF state of the cleaning water heater 25A is controlled by the controller 10. For example, the cleaning water heater 25A is controlled by the controller 10 to maintain the cleaning water at a predetermined temperature based on the water temperature detected by the cleaning water temperature sensor 25B.

[0024] A circular through-hole 20b is formed in the bottom 22A of the storage section 22 of the cleaning water tank 20. The through-hole 20b is a circular plate-like member with a plurality of elongated holes that penetrate in the thickness direction, and is covered by a pump guard 26 that prevents foreign matter from entering. The through-hole 20b is connected to the cleaning pump 5 via a connecting part 50. The connecting part 50 has a first connecting hole 50a that is connected to the through-hole 20b, a drain hole 50b that is connected to a drain pipe 28 that discharges water to the outside of the main body 1, and a second connecting hole 50c that is connected to the cleaning pump 5. The connecting part 50 may be integrally formed with the cleaning pump 5 as part of the casing that constitutes the cleaning pump 5, or it may be provided separately from the cleaning pump 5 as a member that connects the cleaning water tank 20 and the cleaning pump 5.

[0025] The cleaning water tank 20 is provided with an overflow pipe 27 that extends vertically. The overflow pipe 27 allows water exceeding a predetermined level in the cleaning water tank 20 to flow in from its upper end and drain to the outside of the cleaning water tank 20, thereby defining the water level of cleaning water stored in the cleaning water tank 20. The lower end of the overflow pipe 27 is detachably inserted into a drain hole 50b formed in the connection part 50 through a burred pump guard 26 that covers the through hole 20b. By removing the lower end of the overflow pipe 27 from the drain hole 50b, the cleaning water stored in the cleaning water tank 20 can be discharged through the through hole 20b and the drain hole 50b.

[0026] The upper nozzle 3 is located above the washing chamber 1B. The upper nozzle 3 is rotatably mounted on an upper support portion 16 located above the washing chamber 1B.

The main body portion 30 integrally includes a washing spray hole 31 for spraying washing water stored in the washing water tank 20, a washing channel 32 that extends from the rotation center to the washing spray hole 31 and through which washing water flows, a rinsing spray hole 33 for spraying rinsing water stored in the rinsing water tank 6, and a rinsing channel 34 that extends from the rotation center to the rinsing spray hole 33 and through which rinsing water flows. The upper nozzle 3 rotates when the flow of washing water generated in the washing channel 32 or the flow of rinsing water generated in the rinsing channel 34 is converted into rotational force. The upper nozzle 3 is connected to an upper cleaning pipe 58 that supplies cleaning water to the cleaning channel 32 and an upper rinsing pipe 78A that supplies rinsing water to the rinsing channel 34.

[0027] The lower nozzle 4 is located below the washing chamber 1B. The lower nozzle 4 is rotatably mounted on a lower support portion 17 located below the washing chamber 1B. The lower nozzle 4 has a main body portion 40 that extends radially from the base end, which is the rotation center of the rotation axis of the lower nozzle 4, to the tip. The main body portion 40 integrally includes a washing spray hole 41 for spraying washing water stored in the washing water tank 20, a washing channel 42 that extends from the rotation center to the washing spray hole 41 and through which washing water flows, a rinsing spray hole 43 for spraying rinsing water stored in the rinsing water tank 6, and a rinsing channel 44 that extends from the rotation center to the rinsing spray hole 43 and through which rinsing water flows. The lower nozzle 4 rotates when the flow of washing water generated in the washing channel 42 or the flow of rinsing water generated in the rinsing channel 44 is converted into rotational force. The lower nozzle 4 is connected to a lower cleaning pipe 59 that supplies cleaning water to the cleaning channel 42 and a lower rinsing pipe 78B that supplies rinsing water to the rinsing channel 44.

[0028] The dishes D, arranged on the dish rack, are sprayed with washing water by the upper nozzle 3 and the lower nozzle 4 during the washing process, and rinse water is sprayed by the upper nozzle 3 and the lower nozzle 4 during the rinsing process.

[0029] The washing pump 5 is located in the machine room 1A. In the machine room 1A, the washing pump 5 is located to the right of the storage section 22 of the washing water tank 20 and at the rear in the front-to-back direction. In the left-to-right direction, the washing pump 5 is located between the storage section 22 and the rinse water tank 6. The washing pump 5 sends the washing water stored in the washing water tank 20 to the washing chamber 1B which houses the dishes D, etc. The washing pump 5 takes in the washing water from the washing water tank 20 and sends the washing water to the upper nozzle 3 and the lower nozzle 4. The washing pump 5 is connected to the upper washing pipe 58 and the lower washing pipe 59. The upper washing pipe 58 is connected to the upper nozzle 3. The lower washing pipe 59 is connected to the lower nozzle 4.

[0030] The rinse water tank 6 is located in the machine room 1A. In the machine room 1A, the rinse water tank 6 is located to the right of the storage section 22 (washing pump 5) of the washing water tank 20, and at the rear in the front-to-back direction. The rinse water tank 6 is arranged in a line in the front-to-back direction relative to the rinse pump 7. The rinse water tank 6 stores rinse water used for rinsing dishes D, etc. The rinse water is the water sprayed into the washing chamber 1B during the initial hot water supply process and the rinsing process. Water is supplied to the rinse water tank 6 from an external water source via a water supply pipe 60. A strainer 60A is provided in the water supply pipe 60. A valve 60B is provided downstream of the strainer 60A in the water supply pipe 60.

[0031] As shown in Figures 2, 3, and 4, the rinse water tank 6 includes a tank body 61, a rinse water detection unit 62, an overflow unit 63, a rinse water heater 64, and a rinse water temperature sensor 65.

[0032] As shown in Figures 3 and 4, the tank body 61 has a rectangular shape. The tank body 61 has a bottom portion 61A, a first side portion 61B, a second side portion 61C, a third side portion 61D, a fourth side portion 61E, and a lid portion (not shown). The lid portion is detachably provided on the tank body 61.

[0033] As shown in Figure 2, the rinse water detection unit 62 is a switch that detects when the water stored in the tank body 61 is at a constant water level H2. The detection result of the rinse water detection unit 62 is acquired by the controller 10. The valve 60B is controlled by the controller 10. For example, the controller 10 opens and closes the valve in conjunction with the detection of the constant water level H2 by the rinse water detection unit 62, and controls the valve 60B to maintain a constant water level of rinse water stored in the tank body 61.

[0034] The overflow section 63 discharges water that exceeds the maximum water level in the tank body 61. The tank body 61 is a sealed tank, and the water level exceeds the maximum water level when, for example, the valve 60B malfunctions.

[0035] The rinse water heater 64 heats the rinse water stored in the tank body 61 to a predetermined temperature in order to improve the sterilization and rinsing capacity. As shown in Figures 3 and 4, in this embodiment, two rinse water heaters 64 are provided. The two rinse water heaters 64 are arranged at a predetermined distance apart in the vertical direction. Each of the two rinse water heaters 64 has a heater section 64A, a fixing section 64B, and a connecting section 64C.

[0036] The heater section 64A has a meandering shape. The heater section 64A includes a first section 64Aa, a second section 64Ab, and a third section 64Ac that extend in a straight line, a first folded section 64Ad that connects the end of the first section 64Aa to the end of the second section 64Ab, and a second folded section 64Ae that connects the end of the second section 64Ab to the end of the third section 64Ac.

[0037] The first part 64Aa, the second part 64Ab, and the third part 64Ac extend along the longitudinal direction (front-to-back direction) of the tank body 61. The first part 64Aa, the second part 64Ab, and the third part 64Ac are arranged at predetermined intervals in the left-to-right direction and extend substantially parallel to each other. The first part 64Aa is located within the tank body 61 near the first side portion 61B. The third part 64Ac is located within the tank body 61 near the second side portion 61C. The second part 64Ab is located between the first part 64Aa and the third part 64Ac. The first folded portion 64Ad and the second folded portion 64Ae have a curved shape (approximately U-shaped).

[0038] The fixing part 64B secures the rinse water heater 64 to the tank body 61. The fixing part 64B is provided at the base end of the first portion 64Aa of the heater part 64A. The fixing part 64B is inserted through a through hole (not shown) formed in the third side portion 61D of the tank body 61 and is fixed to the third side portion 61D by a fixing nut N. As a result, the rinse water heater 64 is cantilevered to the third side portion 61D. The connecting part 64C is connected to the base end of the first portion 64Aa of the heater part 64A via the fixing part 64B. The connecting part 64C is located outside the tank body 61. An electric wire (not shown) is connected to the connecting part 64C.

[0039] The rinse water heater 64 is supported within the tank body 61 by a support member 66. The support member 66 supports the third portion 64Ac of the heater section 64A. The support member 66 is composed of a first support member 67 and a second support member 68.

[0040] As shown in Figure 6, the first support member 67 has a fixing portion 67A, a support portion 67B, and a connecting portion 67C. The fixing portion 67A, the support portion 67B, and the connecting portion 67C are integrally formed.

[0041] The fixing portion 67A is a plate-shaped member and has a rectangular shape. The fixing portion 67A is fixed to the bottom portion 61A of the tank body 61. Specifically, the fixing portion 67A is fixed to the bottom portion 61A by welding, for example. The fixing portion 67A is provided with positioning holes 67Aa. In this embodiment, the fixing portion 67A is provided with two positioning holes 67Aa. The positioning holes 67Aa penetrate the fixing portion 67A in the thickness direction. The positioning holes 67Aa are, for example, circular in shape. A projection (not shown) provided on the bottom portion 61A is inserted into the positioning holes 67Aa. This determines the position of the fixing portion 67A (first support member 67) relative to the bottom portion 61A.

[0042] The support portion 67B is a plate-shaped member and has a rectangular shape. The support portion 67B is substantially parallel to the fixing portion 67A. The support portion 67B abuts against the third portion 64Ac of the lower of the two rinse water heaters 64, supporting the third portion 64Ac from below. The support portion 67B is provided with a screw hole 67Ba. The screw hole 67Ba is a hole into which a fixing screw S (see Figures 3, 4, and 5) is screwed. The screw hole 67Ba penetrates the support portion 67B in the thickness direction. The support portion 67B is provided with two insertion holes 67Bb and 67Bc. Each of the insertion holes 67Bb and 67Bc penetrates the support portion 67B in the thickness direction. Each of the insertion holes 67Bb and 67Bc is, for example, rectangular in shape.

[0043] The connecting portion 67C connects the fixed portion 67A and the support portion 67B. The connecting portion 67C forms a step between the fixed portion 67A and the support portion 67B.

[0044] As shown in Figure 7, the second support member 68 has a fixing portion 68A, a restricting portion 68B, and a support portion 68C. The fixing portion 68A, the restricting portion 68B, and the support portion 68C are integrally formed.

[0045] The fixing portion 68A is a plate-shaped member and has a rectangular shape. The fixing portion 68A is fixed to the support portion 67B of the first support member 67. The fixing portion 68A is provided with a screw hole 68Aa. The screw hole 68Aa is located at a position corresponding to the screw hole 67Ba of the first support member 67 and is a hole into which the fixing screw S (see Figures 3, 4, and 5) is screwed. The screw hole 68Aa penetrates the fixing portion 68A in the thickness direction. The fixing screw S is screwed into the screw hole 67Ba of the first support member 67 and the screw hole 68Aa of the second support member 68, fixing the second support member 68 to the first support member 67. The fixing screw S fastens the first support member 67 and the second support member 68 together.

[0046] The fixing portion 68A is provided with two insertion portions 68Ab and 68Ac. The insertion portions 68Ab and 68Ac protrude beyond the lower surface of the fixing portion 68A in the thickness direction. The insertion portions 68Ab and 68Ac are provided at positions corresponding to the insertion holes 67Bb and 67Bc of the first support member 67. Insertion portion 68Ab is inserted into the insertion hole 67Bb of the first support member 67. Insertion portion 68Ac is inserted into the insertion hole 67Bc of the first support member 67. This determines the position of the second support member 68 relative to the first support member 67. In addition, since the two insertion portions 68Ab and 68Ac of the second support member 68 are inserted into the insertion holes 67Bb and 67Bc of the first support member 67, the movement of the second support member 68 can be restricted. As a result, even with a configuration in which the first support member 67 and the second support member 68 are fixed by a single fixing screw S, there is no displacement of the position of the second support member 68.

[0047] The restricting portion 68B is a plate-shaped member and has a rectangular shape. The restricting portion 68B is inclined with respect to the fixing portion 68A. As shown in Figure 5, the restricting portion 68B abuts against the third portion 64Ac of the lower of the two rinse water heaters 64, and restricts the movement of the third portion 64Ac to the right.

The second support member 68 supports (holds) both the third portion 64Ac of the lower rinse water heater 64 and the third portion 64Ac of the upper rinse water heater 64.

[0049] As shown in Figures 3 and 4, the support member 66 is positioned closer to the second side portion 61C. No other components are positioned above the fixing screws S (screw holes 67Ba and 68Aa) of the support member 66. Therefore, by removing the lid of the tank body 61, the fixing screws S can be operated from the opening at the top of the tank body 61. Thus, the second support member 68 can be easily attached and detached.

[0050] As shown in Figure 2, the rinse water temperature sensor 65 detects the temperature of the rinse water. The detection result from the rinse water temperature sensor 65 is acquired by the controller 10. The ON / OFF state of the rinse water heater 64 is controlled by the controller 10. For example, the rinse water heater 64 is controlled by the controller 10 to maintain the rinse water at a predetermined temperature based on the water temperature detected by the rinse water temperature sensor 65.

[0051] The rinsing pump 7 is located in the machine room 1A.

The fixing portion 18A and the locking portion 18B are integrally formed.

[0056] The fixing portion 18A is a plate-shaped member and has a rectangular shape. The fixing portion 18A is fixed to the left side of the electrical box 14, for example, by a screw. The locking portion 18B is a plate-shaped member and has a rectangular shape. The locking portion 18B is connected to the upper end of the fixing portion 18A and is provided so as to be approximately perpendicular to the fixing portion 18A. The locking portion 18B is located above the upper surface of the electrical box 14. That is, the locking portion 18B is positioned spaced apart from the upper surface of the electrical box 14.

[0057] As shown in Figure 10, the second mounting fixture 19 is fixed to the bottom surface of the guide portion 21 of the cleaning water tank 20. As shown in Figures 10 and 11, the second mounting fixture 19 has a fixing portion 19A and a support portion 19B. The fixing portion 19A and the support portion 19B are integrally formed.

[0058] The fixing portion 19A is fixed to the bottom surface of the guide portion 21 of the cleaning water tank 20. The fixing portion 19A is fixed, for example, to the bottom surface of the guide portion 21 of the cleaning water tank 20 by welding. The support portion 19B supports (locks) the locking portion 18B of the first mounting fixture 18. The support portion 19B is provided with a slit 19Ba and a guide 19Bb. The slit 19Ba extends along the front-rear direction. The fixing portion 18A of the first mounting fixture 18 is inserted into the slit 19Ba, and the fixing portion 18A is positioned there. The width of the slit 19Ba is slightly wider than the width of the fixing portion 18A of the first mounting fixture 18. The slit 19Ba defines the front-rear and left-right position of the first mounting fixture 18 (electrical box 14). The front-to-back position of the first mounting fixture 18 (electrical box 14) is defined by the fixing portion 18A of the first mounting fixture 18 contacting the rear of the slit 19Ba. The left-to-right position of the first mounting fixture 18 (electrical box 14) is defined by the insertion (positioning) of the fixing portion 18A of the first mounting fixture 18 into the slit 19Ba.

[0059] Guide 19Bb is provided at the front of support portion 19B. Guide 19Bb guides the fixing portion 18A of the first mounting fixture 18, which is inserted into the slit 19Ba, into the slit 19Ba. The front end of guide 19Bb is located behind the front end of support portion 19B. Guide 19Bb is inclined such that its opening narrows from the front to the rear.

[0060] When installing the electrical box 14 in the machine room 1A, the first mounting bracket 18 is attached to the second mounting bracket 19. Specifically, the locking portion 18B of the first mounting bracket 18 is hooked onto the support portion 19B of the second mounting bracket 19, and the electrical box 14 is pushed backward. At this time, the fixing portion 18A is guided into the slit 19Ba by the guide 19Bb, and the fixing portion 18A is inserted into the slit 19Ba. The fixing portion 18A abuts against the rear of the slit 19Ba, thereby defining the front-rear position of the electrical box 14. Once the position of the electrical box 14 is defined, a screw (not shown) is attached to the mounting bracket 14A provided on the front of the electrical box 14, and the mounting bracket 14A is fixed to the frame (not shown). This completes the installation of the electrical box 14 in the machine room 1A.

[0061] As shown in Figures 12 and 13, the main body 1 is provided with a sealing portion 80. The sealing portion 80 is interposed between the main body 1 and the door portion 15 when the door portion 15 is closed. The sealing portion 80 is made of, for example, rubber. The sealing portion 80 is provided on the periphery of the opening 1C in the main body 1. Specifically, the sealing portion 80 is provided on the upper edge 11F and a pair of side edges 11G, 11H in the main body 1. The upper edge 11F and the pair of side edges 11G, 11H form the opening 1C.

[0062] The sealing portion 80 has an upper edge portion 81, a first side edge portion 82, and a second side edge portion 83. The upper edge portion 81, the first side edge portion 82, and the second side edge portion 83 are integrally formed. The upper edge portion 81 is located on the upper edge 11F of the opening 1C. The upper edge portion 81 extends in the left-right direction. The first side edge portion 82 is located on the right side edge 11G of the opening 1C. The first side edge portion 82 extends in the up-down direction. The upper end portion 82A of the first side edge portion 82 is connected to the right end portion 81A of the upper edge portion 81. The second side edge portion 83 is located on the left side edge 11H of the opening 1C. The second side edge portion 83 extends in the up-down direction. The upper end portion 83A of the second side edge portion 83 is connected to the left end portion 81B of the upper edge portion 81.

[0063] As shown in Figure 14, the lower end 82B of the first side edge portion 82 of the sealing portion 80 has an upper end 82Ba and a lower end 82Bb. At the lower end 82B of the first side edge portion 82, when viewed from the front side of the main body portion 1 (viewed from the front-rear direction), the lower end 82Bb is located to the left (towards the opening 1C) of the upper end 82Ba. The lower end 82B of the first side edge portion 82 is inclined downward from the upper end 82Ba towards the lower end 82Bb. The lower end 83B of the second side edge portion 83 of the sealing portion 80 has an upper end 83Ba and a lower end 83Bb. At the lower end 83B of the second side edge portion 83, when viewed from the front side of the main body portion 1 (viewed from the front-rear direction), the lower end 83Bb is located to the right (towards the opening 1C) of the upper end 83Ba. The lower end 83B of the second side edge portion 83 is inclined downward from the upper end 83Ba towards the lower end 83Bb.

[0064] As shown in Figures 15 and 16, the upper end 83Ba of the lower end 83B of the second side edge portion 83 is located above the receiving opening 1E of the water receiving portion 1D. The lower end 83Bb of the lower end 83B of the second side edge portion 83 is located within the water receiving portion 1D below the receiving opening 1E of the water receiving portion 1D. Similarly, the upper end 82Ba of the lower end 82B of the first side edge portion 82 is located above the receiving opening 1E of the water receiving portion 1D. The lower end 82Bb of the lower end 82B of the first side edge portion 82 is located within the water receiving portion 1D below the receiving opening 1E of the water receiving portion 1D.

[0065] As shown in Figure 17, a fixing portion 82C is integrally provided on the first side edge portion 82 of the sealing portion 80. The fixing portion 82C is fitted into a recess 11K provided on the side edge 11G. That is, a part of the sealing portion 80 is fitted into the recess 11K. In this way, the first side edge portion 82 (sealing portion 80) is fixed to the main body portion 1. The recess 11K is provided on the side edge 11G along the vertical direction at a position closer to the opening 1C. The first side edge portion 82 is provided so as to protrude forward from the front surface of the side edge 11G and the recess 11K.

[0066] The door portion 15 is provided with a protrusion 15B that projects toward the main body portion 1 at a position facing the recess 11K of the side edge 11G of the main body portion 1 when the door portion 15 is closed. The protrusion 15B extends along the height direction of the door portion 15. When the door portion 15 is closed, the protrusion 15B presses the first side edge portion 82 of the sealing portion 80 toward the main body portion 1 (towards the depth direction of the recess 11K). As a result, the first side edge portion 82 deforms as shown in Figure 17, and adheres closely to the inner surface of the door portion 15, improving the adhesion. In addition, the first side edge portion 82 has a U-shaped recess in the part of the door portion 15 corresponding to the protrusion 15B, and is spread open when pressed by the protrusion 15B. As a result, the first side edge portion 82 deforms to spread in the left-right direction. At this time, the vertical deformation of the first side edge portion 82 is very small, so the positional relationship between the lower end portion 82B of the first side edge portion 82 and the receiving opening 1E of the water receiving portion 1D remains unchanged.

[0067] A fixing portion is integrally provided on the upper edge portion 81 of the sealing portion 80. The fixing portion is fitted into a recess provided on the upper edge 11F. The recess is provided on the upper edge 11F at a position closer to the opening 1C and along the left-right direction. The upper edge portion 81 is provided so as to protrude forward from the front surface of the upper edge 11F and the recess. The door portion 15 is provided with a protrusion that protrudes toward the main body portion 1 at a position facing the recess on the upper edge 11F of the main body portion 1 when the door portion 15 is closed. The protrusion extends along the left-right direction. When the door portion 15 is closed, the protrusion presses the upper edge portion 81 toward the main body portion 1. As a result, the upper edge portion 81 deforms and adheres closely to the inner surface of the door portion 15, improving the adhesion. In addition, the upper edge portion 81 has a U-shaped recess in the part corresponding to the protrusion of the door portion 15, and is spread open when pressed by the protrusion. As a result, the upper edge portion 81 deforms to widen in the vertical direction.

[0068] A fixing portion is integrally provided on the second side edge portion 83 of the sealing portion 80. The fixing portion is fitted into a recess provided on the side edge 11H. The recess is provided on the side edge 11H in the vertical direction at a position closer to the opening 1C. The second side edge portion 83 is provided so as to protrude forward from the front surface of the side edge 11H and the recess. The door portion 15 is provided with a protrusion that protrudes toward the main body portion 1 at a position facing the recess on the side edge 11H of the main body portion 1 when the door portion 15 is closed. The protrusion extends along the height direction of the door portion 15. When the door portion 15 is closed, the protrusion presses the second side edge portion 83 toward the main body portion 1. As a result, the second side edge portion 83 deforms and adheres closely to the inner surface of the door portion 15, improving the adhesion. In addition, the second side edge portion 83 has a U-shaped recess in the part corresponding to the protrusion of the door portion 15, and is spread open when pressed by the protrusion. As a result, the second side edge portion 83 deforms to spread out in the left-right direction. At this time, the vertical deformation of the second side edge portion 83 is very small, so the positional relationship between the lower end portion 83B of the second side edge portion 83 and the receiving opening 1E of the water receiving portion 1D remains unchanged.

[0069] As described above, in the dishwasher 100 according to this embodiment, the lower end portion 82B of the first side edge portion 82 of the sealing portion 80 has an upper end 82Ba and a lower end 82Bb. When viewed from the front side of the main body portion 1, the lower end 82Bb is located closer to the opening 1C than the upper end 82Ba, and the lower end 82Bb is inclined downward from the upper end 82Ba to the lower end 82Bb. The upper end 82Ba of the lower end portion 82B of the first side edge portion 82 is located above the receiving opening 1E, and the lower end 82Bb of the lower end portion 82B is located below the receiving opening 1E within the water receiving portion 1D. Similarly, the lower end portion 83B of the second side edge portion 83 of the sealing portion 80 has an upper end 83Ba and a lower end 83Bb. When viewed from the front side of the main body portion 1, the lower end 83Bb is located closer to the opening 1C than the upper end 83Ba, and the lower end 83Bb is inclined downward from the upper end 83Ba to the lower end 83Bb. The upper end 83Ba of the lower end 83B of the second side edge portion 83 is located above the receiving opening 1E, and the lower end 83Bb of the lower end 83B is located below the receiving opening 1E within the water receiving portion 1D.

[0070] As a result, in the dishwasher 100, if water leaks from a point of low airtightness in the sealing portion 80 and flows to the lower ends 82B, 83B of the first side edge portion 82 and / or the second side edge portion 83, the water flows along the slope from the upper ends 82Ba, 83Ba to the lower ends 82Bb, 83Bb, and drips (discharges) from the lower ends 82Bb, 83Bb into the water receiving portion 1D. Since the water receiving portion 1D is in communication with the washing chamber 1B, the water discharged into the water receiving portion 1D is discharged into the washing chamber 1B. Therefore, in the dishwasher 100, it is possible to prevent water dripping from the sealing portion 80 from flowing out of the washing chamber 1B.

[0071] In the dishwasher 100 according to this embodiment, the main body 1 is provided with a recess 11K into which the sealing portion 80 is fitted. The door portion 15 is provided with a protrusion 15B that projects toward the main body 1 at a position facing the recess 11K when the door portion 15 is closed. In this configuration, when the door portion 15 is closed, the protrusion 15B of the door portion 15 presses against the sealing portion 80. Therefore, the airtightness between the main body 1 and the door portion 15 can be improved.

[0072] In the dishwasher 100 according to this embodiment, the rinse water heater 64 is supported in the rinse water tank 6 by a first support member 67 and a second support member 68. The second support member 68 supports the third portion 64Ac of two rinse water heaters 64 with a single component. Therefore, the number of parts can be reduced. Furthermore, the third portion 64Ac of two rinse water heaters 64 can be supported simultaneously by the operation of installing one second support member 68. Therefore, compared to the case where separate members are used to support the third portion 64Ac of two rinse water heaters 64, work efficiency can be improved.
