[0065] The advantages and features of this disclosure, as well as the methods for implementing them, will become clear from the following detailed description of embodiments with reference to the accompanying drawings. However, this disclosure may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. This disclosure is defined only by the scope of the claims. Throughout the specification, the same reference numerals denote the same elements.

[0066] The dishwasher will be described below with reference to the accompanying drawings of this disclosure.

[0067] refer to Figure 1 This section will briefly describe the appearance of the dishwasher.

[0068] The dishwasher includes a tub 10 that forms the washing space. The tub 10 may have an opening at the front.

[0069] The dishwasher includes a door 12 that opens and closes the front of the opening of the tub 10.

[0070] The dishwasher includes a base 14 disposed below the tub 10. Multiple components can be arranged in the space between the tub 10 and the base 14.

[0071] The dishwasher may include a side cover 30 disposed on the side of the tub 10.

[0072] Reference Figure 2 This will describe the water flow and refrigerant flow in the dishwasher.

[0073] The storage tank 32 is located below the bucket 10. A drain pump 39 is located on one side of the storage tank 32 to drain the water stored in the storage tank 32 to the outside.

[0074] A washing pump 34 is disposed on one side of the storage tank 32 to supply water stored in the storage tank 32 to the tank 10. The washing pump 34 may have a heater (not shown). Therefore, the heater can heat the water supplied to the tank 10 through the washing pump 34.

[0075] A water softener 38 may be installed on one side of the storage tank 32. The water softener 38 is connected to the storage tank 32. It can supply water from an external source to the storage tank 32. The water softener 38 can reduce the hardness of the water supplied to the storage tank 32.

[0076] The heat pump module 100 can be installed on one side of the washing pump 34.

[0077] The heat pump module 100 allows refrigerant to flow using the compressor 102 and can heat the water supplied to the tank 10.

[0078] The heat pump module 100 includes a condenser 104 that transfers heat between the refrigerant and water and heats the water supplied to the tank 10.

[0079] The heat pump module 100 includes an evaporator 106 that transfers heat between a refrigerant and air. The heat pump module 100 includes a fan 108 disposed on one side of the evaporator 106 to form an airflow to the evaporator 106.

[0080] The heat pump module 100 includes an expansion valve 110 disposed between the condenser 104 and the evaporator 106.

[0081] The condenser 104 is connected between the wash pump 34 and the tank 10. Therefore, water supplied to the tank 10 by the wash pump 34 can pass through the condenser 104. The condenser 104 heats the water supplied to the tank 10.

[0082] The washing pump 34 may have a heater (not shown). The washing pump 34 may activate the heater to generate steam. The washing pump 34 may include a steam supply pipe 36 directly connected to the tank 10.

[0083] Reference Figure 3 This will describe the base of the dishwasher and the components arranged on the base.

[0084] The base 14 is located below the barrel 10. The base 14 can be configured such that its lower surface is in contact with the ground.

[0085] Multiple components can be mounted on the base 14.

[0086] A storage tank 32 for storing water supplied to the barrel 10 is provided on the base 14.

[0087] A washing pump 34 for supplying water stored in the storage tank 32 to the bucket 10 can be mounted on the base 14. The washing pump 34 is mounted on one side of the storage tank 32.

[0088] A water softener 38 is mounted on the base 14. The water softener 38 can reduce the hardness of the water supplied to the storage tank 32.

[0089] The heat pump module 100 is mounted on the base 14. The heat pump module 100 is detachably mounted on the base 14. The heat pump module 100 can be slidably inserted into or removed from the base 14.

[0090] The heat pump module 100 includes a module tray 120 that is detachably mounted on a base 14.

[0091] The heat pump module 100 includes a compressor 102, a condenser 104, an evaporator 106, and a fan 108.

[0092] The heat pump module 100 includes an expansion valve 110.

[0093] The compressor 102, condenser and evaporator 106 are mounted on the module tray 120.

[0094] However, it is also possible to set only some of the compressor 102, condenser and evaporator 106 on the module tray.

[0095] For structural stability, the compressor 102 can be mounted on a base, and the structure can be configured such that the compressor, exposed through the gap, can be disassembled by the user after the module tray 120 is removed. In this case, the pipe between the compressor 102 and the heat exchanger placed on the module tray 120 can be formed of a flexible or flowable material and can be of sufficient length to prevent stress even after removal.

[0096] Unlike the attached diagram, the filter assembly 40 can also be mounted on the module tray 120. In this case, the filter can be replaced when the filter assembly 40 has been removed from the dishwasher by the module tray 120. A fan 108 is mounted on the module tray 120. The fan 108 is positioned on one side of the evaporator 106. The condenser 104 can be a plate heat exchanger that transfers heat between the water and refrigerant supplied to the tank 10.

[0097] A module cover 70, located on one side of the heat pump module 100, is mounted on the base 14. The module cover 70 secures the heat pump module 100 mounted on the base 14 in a suitable position.

[0098] The module cover 70 is attached to the base 14. The module cover 70 may also be attached to the heat pump module 100. When the module cover 70 is removed from the base 14, the heat pump module 100 can be removed from the base 14.

[0099] Electronic components such as the main controller and PCB of a dishwasher can be installed onto the module cover 70.

[0100] For ease of maintenance and repair of electrical components, the module cover 70 can be removed from the base 14. Additionally, the module cover 70 can be used to secure and cover the heat pump module 100. A filter device 40 for filtering the air supplied to the evaporator 106 is provided on the base 14.

[0101] The filter device 40 may have a filter (not shown) disposed therein. The filter device 40 may include a cap 58 for opening the upper part to allow replacement of the filter disposed therein.

[0102] An inlet (not shown) may be formed on one side of the filter device 40. Even if the cap 58 is installed in the filter device 40, air can flow into the filter device 40 through the inlet (not shown).

[0103] The filter device 40 is connected to the heat pump module 100. Specifically, the filter device 40 is connected to one side of the evaporator 106. Therefore, air introduced into the filter device 40 can flow to the evaporator 106.

[0104] An exhaust duct 16 is disposed on one side of the base 14. The exhaust duct 16 is connected to the heat pump module 100. The base 14 includes an exhaust duct 16 for discharging air moved by the fan 108 from the base.

[0105] When the heat pump module 100 is installed on the base 14, the exhaust pipe 16 is located on one side of the fan 108. Therefore, the air moved by the fan 108 can be discharged from the base 14 through the exhaust pipe 16.

[0106] Reference Figure 4 This will describe the arrangement of the heat pump modules mounted on the base.

[0107] When the heat pump module 100 is installed on the base 14, the evaporator 106 and the fan 108 are positioned between the filter device 40 and the exhaust pipe 16.

[0108] The filter assembly 40 is fixedly mounted on the base 14. Only the cap 58 of the filter assembly 40 can be removed from the filter assembly 40.

[0109] The filter device 40 directs the incoming air to the evaporator 106. Therefore, the air introduced into the filter device 40 can flow through the evaporator 106 and the fan 108 to reach the exhaust duct 16.

[0110] When the heat pump module 100 is installed on the base 14, the compressor 102 and the condenser 104 are positioned closer to the module cover 70 than the evaporator 106.

[0111] The module cover 70 can be configured to cover one side of the compressor 102 and the condenser 104.

[0112] The condenser 104 is located between the compressor 102 and the expansion valve 110.

[0113] The condenser 104 is configured such that the connection surface 104a to which the refrigerant hose 105 or water hose (not shown) is connected faces the expansion valve 110. The connection surface 104a of the condenser 104 is arranged in a direction adjacent to the wash pump 34 (see [link]). Figure 3 ).

[0114] Reference Figure 5 This will describe a heat pump module that can be detached from the base.

[0115] The heat pump module 100 can be moved to one of the left or right sides of the base 14.

[0116] Once the heat pump module 100 is removed from the base 14, the fan 108 can be removed from the exhaust duct 16. Once the heat pump module 100 is removed from the base 14, the evaporator 106 can be removed from the filter assembly 40.

[0117] When the module tray 120 is removed from the base 14, the heat pump module 100 is removed from the base 14.

[0118] Once the heat pump module 100 is removed from the base 14, the evaporator 106, fan 108, compressor 102, and condenser 104 mounted on the module tray 120 can be moved together. Therefore, the heat pump module 100 can be removed from the base 14, allowing the heat pump module 100 to be managed independently.

[0119] Furthermore, the components arranged on the base 14 can be managed through the area where the heat pump module 100 is removed.

[0120] Reference Figure 6 The description will cover the cap that can be removed from the filter device.

[0121] The filter device 40 is fixedly mounted on the base 14. The filter device 40 is fixed in the appropriate position and attached to the base 14.

[0122] Filter 56 may be disposed within filter assembly 40. Cap 58 is detachably attached to filter assembly 40. When cap 58 is removed from filter assembly 40, filter 56 disposed within filter assembly 40 may be removed.

[0123] Cap 58 is disposed on the bottom plate 10a of barrel 10. Therefore, cap 58 is detached upward from the bottom plate 10a of barrel 10. Through hole 10b for connector 60 to pass through is formed in the bottom plate 10a of barrel 10.

[0124] When the cap 58 is attached to the filter assembly 40, the cap 58 is positioned on the bottom plate 10a of the barrel 10. When the cap 58 is removed from the filter assembly 40, the filter 56 can be removed upwards from the bottom plate 10a of the barrel 10.

[0125] Therefore, the user can pass through the inside of the bucket 10 to replace the filter 56 located in the filter device 40.

[0126] Reference Figure 7 The filter device will be described.

[0127] The filter device 40 includes a filter device body 42, a connector 60, and a cap 58. The filter device body 42 forms a space for installing a filter 56. The connector 60 is disposed above the filter device body 42 and forms an inlet 60a. The cap 58 is disposed on top of the connector 60.

[0128] Filter 56 is disposed within filter assembly body 42. Filter assembly body 42 directs air to evaporator 106.

[0129] Connector 60 connects the filter assembly body 42 and cap 58. Connector 60 is mounted above the filter assembly body 42. A separate inlet 60a is formed in connector 60. A portion of connector 60 protrudes upward beyond the bottom plate 10a of barrel 10. Therefore, cap 58, which is located above the bottom plate 10a of barrel 10, can be connected to connector 60.

[0130] Reference Figure 8 and Figure 9 The structure of the heat pump module will be described.

[0131] The heat pump module 100 includes a module tray 120, and a compressor 102, an evaporator 106 and a condenser 104 are disposed in the module tray 120.

[0132] The module tray 120 can be slidably attached to the base 14. The module tray 120 can be slidably attached to the base 14. The module tray 120 can be detachably mounted on the base 14.

[0133] The module tray 120 includes a tray base 122 disposed on the base 14.

[0134] The modular tray 120 includes tray sidewalls 124 and 126 that extend upward from the tray base 122 and contact the base sidewalls 18 and 20 of the base 14.

[0135] The tray base 122 and base 14 form a double bottom surface. The load of the components mounted in the modular tray 120 can be well supported by the double bottom surface.

[0136] However, unlike the attached figures, it is also possible that the base 14 does not form a bottom surface in the area where the tray base 122 is located. In this case, the tray base 122 does not form a double bottom surface with the base 14.

[0137] That is, the tray base 122 can form a continuous surface with the base 14. The tray base 122 can form a single bottom surface on one side of the base 14. In this case, the base 14 can guide the movement of the module tray 120. That is, the base 14 can be disposed around the periphery of the tray sidewalls 124 and 126.

[0138] In this structure, the material cost of the base 14 can be reduced. Furthermore, the bottom surface can be opened when the module tray 120 is removed from the base 14. In other words, this structure allows for easier maintenance of other components.

[0139] Guide grooves 124a and 126a are formed in the sidewalls 124 and 126 of the tray. Guide grooves 124a and 126a form inward recesses in the sidewalls 124 and 126 of the tray. Guide grooves 124a and 126a extend in the direction of movement of the module tray 120.

[0140] As described below, the guide ribs 18a and 20a formed on the base sidewalls 18 and 20 of the base 14 can be inserted into the guide grooves 124a and 126a.

[0141] The module tray 120 includes a first tray sidewall 124 and a second tray sidewall 126, the second tray sidewall 126 being spaced apart from the first tray sidewall 124. The first tray sidewall 124 is arranged parallel to the second tray sidewall 126.

[0142] The first tray sidewall 124 and the second tray sidewall 126 are arranged to face each other.

[0143] The compressor 102 is disposed between the first tray sidewall 124 and the second tray sidewall 126. The condenser 104 is disposed between the first tray sidewall 124 and the second tray sidewall 126.

[0144] A first guide groove 124a is formed in the first tray sidewall 124. A second guide groove 126a is formed in the second tray sidewall 126.

[0145] Fan 108 is located on one side of the second tray sidewall 126.

[0146] The module tray 120 includes an evaporator cover 128, which forms a space for mounting the evaporator 106. The module tray 120 also includes a fan cover 130, which forms a space for mounting the fan 108.

[0147] The evaporator cover 128 is located on one side of the fan cover 130.

[0148] The module tray 120 may include an upper cover 132 disposed above the evaporator cover 128 and the fan cover 130. The evaporator cover 128, the fan cover 130 and the upper cover 132 may also be integrally formed.

[0149] On the side of the evaporator cover 128 facing the filter device 40, a side end 128a protruding toward the filter device 40 may be provided. The side end 128a can be inserted into a side groove 52a formed in the filter device 40, as will be described below.

[0150] In other words, when the module tray 120 is installed on the base 14, the side end 128a is inserted into the side groove 52a of the filter device 40.

[0151] refer to Figure 10 This will describe a portion of the base that connects to the heat pump module.

[0152] The base 14 includes base sidewalls 18 and 20 extending in the direction of movement of the module tray 120. The base 14 includes a first base sidewall 18 and a second base sidewall 20 disposed spaced apart from the first base sidewall 18.

[0153] The first base sidewall 18 is configured to face the first pallet sidewall 124. The second base sidewall 20 is configured to face the second pallet sidewall 126.

[0154] The first guide rib 18a is disposed on the side wall 18 of the first base. When the module tray 120 is installed on the base 14, the first guide rib 18a is inserted into the first guide groove 124a of the side wall 124 of the first tray.

[0155] The second guide rib 20a is disposed on the side wall 20 of the second base. When the module tray 120 is installed on the base 14, the second guide rib 20a is inserted into the second guide groove 126a of the side wall 126 of the second tray.

[0156] refer to Figure 11 and Figure 12 This will describe the end walls of the base.

[0157] The base 14 includes an end wall 22 that bends and extends from the second base side wall 20. The end wall 22 can form a space for mounting the washing pump 34.

[0158] The base 14 includes an end wall 22, and one end of the module tray 120 contacts the end wall 22.

[0159] A spacer protrusion 22a is disposed on the end wall 22 to restrict the upward movement of the module tray 120. The module tray 120 may be disposed below the spacer protrusion 22a. The spacer protrusion 22a may be configured to be spaced upward from the bottom surface of the base 14 by a predetermined distance.

[0160] When the heat pump module 100 is installed on the base 14, a portion of the module tray 120 may be positioned below the spacer protrusion 22a.

[0161] Reference Figure 13 This will describe the connection between one side of the filter unit and the heat pump module.

[0162] An outlet 44, opening toward the evaporator 106, is formed on one side of the filter assembly 40. The filter assembly 40 includes a peripheral wall 46 forming the outlet 44.

[0163] The outer wall 46 includes an upper wall 48 disposed above the outlet 44 and a lower wall 50 disposed below the outlet 44.

[0164] The outer wall 46 includes opposing side walls 52 disposed on both sides of the outlet 44 (see...). Figure 13 ).

[0165] The filter device 40 includes an upper end 48a, which is located at the upper end of the peripheral wall 46 and protrudes toward the evaporator 106. The filter device 40 also includes a lower end 50a, which is located at the lower end of the peripheral wall 46 and protrudes toward the evaporator 106.

[0166] The upper end 48a protrudes from the lower end of the upper wall 48 toward the evaporator 106. The lower end 50a protrudes from the upper end of the lower wall 50 toward the evaporator 106.

[0167] The upper end 48a is located below the upper wall of the evaporator cover 128. The lower end 50a is located above the lower wall of the evaporator cover 128.

[0168] The upper end 48a and the lower end 50a can hold the evaporator 106 in the proper position. In addition, the upper end 48a and the lower end 50a can guide the lateral movement of the evaporator 106.

[0169] Reference Figure 14 This will describe the connection between the filter unit and the other side of the heat pump module.

[0170] The outer wall 46 includes opposing sidewalls 52 disposed on both sides of the outlet 44. Each sidewall 52 has a side groove 52a formed therein. The side groove 52a extends vertically.

[0171] The side end 128a of the evaporator 106 is inserted into the side groove 52a formed in each sidewall 52. When the heat pump module 100 is mounted to the base 14, the side end 128a is inserted into the side groove 52a. Therefore, the lateral movement of the heat pump module 100 can be restricted.

[0172] The inner rib 54 is provided inside the filter device body 42 to guide the air flowing through the filter 56 toward the evaporator 106.

[0173] The filter device body 42 includes a filter placement part 42a and an air guide part 42b. The filter 56 is disposed in the filter placement part 42a, and the inner rib 54 is disposed in the air guide part 42b.

[0174] The cross-sectional area of ​​the flow path from the filter placement section 42a to the air guide section 42b is smaller than the cross-sectional area of ​​the outlet 44. Therefore, the air flowing to the evaporator 106 through the outlet 44 can mainly flow to one side of the evaporator 106.

[0175] Such airflow reduces the heat exchange performance of the evaporator 106. Therefore, multiple inner ribs 54 are provided inside the air guide section 42b. The inner ribs 54 allow the air flowing from the filter placement section 42a to flow evenly across the evaporator 106.

[0176] The multiple inner ribs 54 may have an L-shaped curved shape. The multiple inner ribs 54 may be arranged to be spaced apart from each other. Each of the multiple inner ribs 54 may extend to the outlet 44.

[0177] In the following text, refer to Figures 15 to 17 This will describe the placement of the module cover and the location where the heat pump module is removed.

[0178] The module cover 70 can be located on one side of the base 14. For example... Figure 15 As shown, the module cover 70 can be disposed on the side surface of the base 14. In this case, once the module cover 70 is removed from the base 14, the heat pump module 100 can be removed laterally from the base 14. Unlike the attached figures, the module cover 70 can also be disposed on the side surface of the base 14. Figure 15 The side surfaces of the structure are opposite each other on the side surfaces.

[0179] If the heat pump module 100 is a structure that can be removed laterally from the base 14, it facilitates the installation of the module cover 70. The module cover 70 can be disposed in the gap formed between the base 14 and the barrel 10.

[0180] If the heat pump module 100 is a structure that can be removed in the lateral direction of the base 14, it can facilitate the formation of an air passage to the rear of the dishwasher. Furthermore, in a built-in structure, there is the advantage that the dishwasher can be pulled out only one unit length in the front-to-back direction from the sink mounting position, allowing the heat pump module 100 to be removed.

[0181] In addition, module cover 70 can be as follows Figure 16 As shown, it is located at the front of the base 14, or it can be as follows: Figure 17 It is shown to be located at the rear of the base 14.

[0182] If the heat pump module 100 is designed to be removed from the base 14, it can be removed by removing the cover (not shown) of the dishwasher's kickboard section. Furthermore, in a built-in design, the heat pump module 100 can be removed separately from the front without pulling out the entire dishwasher.

[0183] exist Figure 16 In this case, once the module cover 70 is removed from the base 14, the heat pump module 100 can be taken forward from the base 14.

[0184] In addition, Figure 17 In this case, once the module cover 70 is removed from the base 14, the heat pump module 100 can be removed from the base 14 backwards.

[0185] The rear portion of the base 14 may have a structure with relatively greater rigidity compared to the front or sides in order to support the load of the barrel 10. Therefore, even when the heat pump module 100 is removed from the base 14, the structure in which the heat pump module 100 can be removed rearward from the base 14 provides structural stability.

[0186] That is, the heat pump module can be placed in the appropriate position and removed according to the arrangement of the space between the base 14 and the bucket 10. The placement of the heat pump module 100 can be determined according to the placement of the module cover 70. In addition, the module tray 120 can also be installed so that it can be removed from the base 14 in all directions (backward, forward and sideways).

[0187] While exemplary embodiments have been shown and described above, this disclosure is not limited to the above embodiments, and various modifications can be made by those skilled in the art to the embodiments without departing from the spirit of this disclosure, and such modifications should not be understood solely from the technical spirit or prospect of this disclosure.
