[0054] In modern life, dishwashers have brought great convenience to people with hot water washing and drying functions. However, in the related art, the heating module and the drying module of the dishwasher are mostly designed independently. For example, the heating module often uses a washing pump with heating function to heat the washing water through the pump body, which can achieve hot water washing, but such a special heating washing pump is expensive; for the drying module, the condensation drying system is common, which realizes drying by condensing water vapor into water through cooling water, but this system involves complex pipeline layout and high cost. The high cost not only limits the market popularization of the dishwasher, but also increases the purchase burden of consumers.

[0055] To this end, the embodiments of the present application provide a dishwasher with simple structure and low cost.

[0056] Specifically, please refer to Figures 1 to 6 , Figure 1 a structural schematic diagram of the dishwasher provided by the embodiments of the present application;

[0057] Figure 2 a structural schematic diagram of the partition piece 20, the water cup assembly 30 and the spray arm 52 provided by the embodiments of the present application; Figure 3 an exploded view of the partition piece 20, the water cup assembly 30 and the spray arm 52 provided by the embodiments of the present application; Figure 4 a structural schematic diagram of the heating piece 32 provided by the embodiments of the present application; Figure 5 an internal structural schematic diagram of the partition piece 20 and the water cup assembly 30 provided by the embodiments of the present application; Figure 6 is Figure 5 an enlarged view of position A in FIG.

[0058] The dishwasher of the embodiments of the present application comprises a shell, a base, an inner container 10, a door body and a water cup assembly 30.

[0059] The shell and the base of the dishwasher constitute the basic framework of the entire dishwasher. The shell wraps the inner container 10 and other internal components, serving to protect the internal structure and beautify the appearance. The base is used to support the inner container 10 and the internal structure of the entire dishwasher, ensuring that the dishwasher remains stable during operation. The base is usually made of a sturdy and durable material, such as high-strength plastic or metal, to withstand the various weights and pressures generated by the inner container 10, tableware, and the washing process. The base can be provided with support feet with reinforcing ribs to further enhance stability. The shell can be made of different materials according to different design requirements, such as a metal shell providing better durability and texture, or a plastic shell focusing on lightness and cost control.

[0060] The inner container 10 of the embodiment is a key component of the dishwasher, which builds a washing inner cavity 100 for accommodating tableware. The inner container 10 can be formed by a top plate, a bottom plate, left and right side plates, and a back plate, forming a relatively closed space to prevent water and detergent from leaking during the washing process, ensuring that the washing work is carried out in a stable environment. For example, during the water spraying washing stage, the inner container 10 can withstand the internal water pressure to ensure that water does not seep out, thereby achieving efficient cleaning of tableware.

[0061] In one embodiment, a dish rack is installed in the washing inner cavity 100 for placing tableware. The dish rack is arranged in a movable manner, for example, it can be pushed and pulled in the washing inner cavity 100. In this way, the user can flexibly adjust the position of the dish rack according to the type and quantity of tableware, to better adapt to the placement needs of different tableware. For example, when a large number of plates need to be cleaned, the dish rack can be pulled out to arrange the plates neatly on the dish rack, and then pushed back into the washing inner cavity 100 for cleaning.

[0062] The door body of the embodiment is movably connected to the opening of the inner container 10, and can be arranged in a rotating manner. The rotating connection allows the door body to be easily opened and closed, facilitating the user to take and place tableware. For example, the user only needs to pull or push the door body slightly, and the door body can smoothly rotate around the rotating shaft to realize the opening and closing actions.

[0063] In one embodiment, a control panel for controlling the washing program is arranged on the door body. The control panel integrates various operation buttons and a display screen, and the user can select different washing modes such as standard washing and quick washing through the operation buttons to adapt to the cleaning needs of different types of tableware. The display screen displays the working status of the dishwasher in real time, such as the remaining washing time, the current washing mode, and other information. For example, after placing the tableware, the user can select the appropriate washing mode through the control panel on the door body, start the dishwasher, and then start the automatic washing process. During the washing process, the user can always know the working progress of the dishwasher through the display screen.

[0064] The inner container 10 of the embodiment can form one or more cavities to accommodate different dishware washing requirements.

[0065] In one embodiment, as shown in Figure 1 The dishwasher further includes a partition 20, which is arranged inside the inner container 10 and can be a partition plate. The partition 20 divides the washing cavity 100 into an upper washing cavity 101 and a lower washing cavity 102. The partition 20 and the inner wall of the inner container 10 can be detachably connected. For example, the inner wall of the inner container 10 is provided with a plurality of spaced mounting slots in the height direction, and the partition 20 can be mounted in different mounting slots according to actual needs. By changing the position of the partition 20 in the mounting slot, the volume of the upper washing cavity 101 and the lower washing cavity 102 can be flexibly adjusted. When more large dishes need to be cleaned, the partition 20 can be installed at a higher position to increase the volume of the lower washing cavity 102 to accommodate large dishes. When more small dishes need to be cleaned, the partition 20 can be installed at a lower position to expand the space of the upper washing cavity 101. This flexible design can better meet the diversified needs of different users for cleaning different dishes and improve the efficiency of the dishwasher.

[0066] During the operation of the dishwasher, the user can place different dishes in the upper washing cavity 101 and the lower washing cavity 102 according to the type, size and quantity of the dishes. For example, small and fragile dishes such as tea cups and small bowls are placed in the upper washing cavity 101, and large and heavily soiled dishes such as large plates and pots are placed in the lower washing cavity 102. This partition design allows the dishwasher to wash different types of dishes, improving the specificity and efficiency of dish washing.

[0067] The water cup assembly 30 of the embodiment includes a water storage cup 31 and a heating element 32. When the washing cavity 100 is provided with only one, the water cup assembly 30 is arranged at the bottom of the washing cavity 100. When the washing cavity 100 is provided with an upper washing cavity 101 and a lower washing cavity 102, the water cup assembly 30 can be arranged in the upper washing cavity 101, the lower washing cavity 102, or both.

[0068] Specifically, the water storage cup 31 is arranged at the bottom of the partition 20 and / or the lower washing cavity 102 and communicates with the washing cavity 100. Hereinafter, the water storage cup 31 arranged at the partition 20 is taken as an example for description.

[0069] The shape and capacity of the water storage cup 31 are determined according to the design requirements of the dishwasher and generally have a certain depth and volume to store enough washing water.

[0070] The water storage cup 31 can be made of plastic, stainless steel, etc. by injection molding or stamping forming process. The connection mode between the water storage cup 31 and the partition 20 can be clamping, bolt connection or integrated forming, etc. to ensure firm connection and good sealing to prevent washing water leakage.

[0071] When the dishwasher works, the washing water in the washing cavity 100 flows into the water storage cup 31 under the action of gravity, and the water storage cup 31 plays a role of storing washing water to provide a stable water source for the washing process. When the washing pump 51 is started, the washing water in the water storage cup 31 is pumped out, transported to the spray arm 52 through the pipeline, and the spray arm 52 sprays the washing water onto the tableware to realize cleaning of the tableware. This design enables the washing water to be recycled in the washing system, improves the utilization rate of water resources, and reduces energy consumption.

[0072] The heating element 32 of the embodiment is a key component of the water cup assembly 30, which is not only used for heating washing water, but also used for heating air in the washing cavity 100 to dry the tableware.

[0073] Specifically, the heating element 32 extends into the water storage cup 31 and is spaced apart from the inner wall of the water storage cup 31, that is, the heating element 32 is in an overhanging state in the water storage cup 31. The heating element 32 usually adopts heating elements such as resistance wire and heating tube, and its shape and size are designed according to the internal space of the water storage cup 31 to ensure that it can fully contact with the washing water.

[0074] Exemplarily, the heating element 32 is fixed to the inner wall of the water storage cup 31 by fixing devices such as brackets and buckles to ensure its stable position in the water storage cup 31. The heating element 32 is connected with the power supply system of the dishwasher, and the heating power is adjusted and controlled through the control system.

[0075] Since the heating element 32 is in an overhanging state and fully contacts with the washing water, on the one hand, compared with the heating element 32 being attached to the wall, the contact area between the heating element 32 and the washing water is increased to a greater extent, so that the heat can be quickly and uniformly transferred to the washing water, greatly improving the efficiency of heating the washing water, and the washing water can be quickly heated to an appropriate temperature, enhancing the activity of the detergent, accelerating the dissolution and separation of oil stains, and improving the washing effect. On the other hand, during the drying stage, when the heating element 32 heats the air, since it is spaced apart from the inner wall of the water storage cup 31, the air can flow more freely around it, which is conducive to the formation and circulation of hot air, improving the efficiency of heating the air, and the hot air can be quickly dispersed into the washing cavity 100 to accelerate the evaporation of water on the surface of the tableware, realizing efficient drying.

[0076] The dishwasher also includes a drain water path 40 and a washing water path 50. Exemplarily, the drain water path 40 includes a drain pump 41 and a drain pipe. The drain pipe is made of a corrosion-resistant material, such as plastic. The drain pump 41 provides the power for drainage. The drain pipe is connected to the water reservoir 31 and the external drain outlet via a sealed connection to ensure no leakage occurs during drainage. The drain pump 41 is connected to the drain pipe and is electrically connected to the dishwasher's control system to achieve automatic drainage control.

[0077] The washing water circuit 50 includes a washing pump 51 and a spray arm 52. The water inlet of the washing pump 51 is connected to the water storage cup 31, and the water outlet of the washing pump 51 is connected to the spray arm 52.

[0078] During the washing stage, the user places the dishes in the upper washing chamber 101 or the lower washing chamber 102 and starts the dishwasher. Washing water flows into the water storage cup 31, and the heating element 32 begins to heat the washing water in the water storage cup 31. When the washing water reaches the set temperature, the washing pump 51 starts, drawing the hot water from the water storage cup 31 and delivering it through pipes to the spray arm 52. The spray arm 52 sprays the hot water onto the dishes at a certain pressure and angle, rinsing and cleaning them. The washed water then flows back into the water storage cup 31, forming a circulating washing process.

[0079] After the washing cycle is complete, the drain pump 41 starts to drain the washing water from the water storage cup 31 and the washing chamber 100 of the dishwasher.

[0080] After drainage is complete, the heating element 32 no longer comes into contact with the washing water, but instead directly heats the air in the washing chamber 100. The heated air circulates in the washing chamber 100, carrying away the moisture from the surface of the tableware and drying it.

[0081] As can be seen, the dishwasher of this embodiment has the following beneficial effects:

[0082] First, the heating element 32 simultaneously achieves heating, washing, and drying functions, eliminating the need for a complex independent drying device, simplifying the dishwasher's structure, reducing production costs, and improving the product's cost-effectiveness.

[0083] Secondly, the heating element 32 is spaced apart from the inner wall of the water storage cup 31, which improves the efficiency of heating the washing water and air, shortens the washing and drying time, and further improves the efficiency of the dishwasher.

[0084] Finally, the divider 20 divides the washing chamber 100 into an upper washing chamber 101 and a lower washing chamber 102, enabling the dishwasher to wash different types of tableware, improving washing efficiency and effectiveness, and meeting diverse user needs.

[0085] In one embodiment, such as Figure 4As shown, the heating element 32 includes a heating part 321, a mounting part 322 and an electricity connection part 323.

[0086] The heating part 321 is provided in a tubular shape, which can increase the contact area with the washing water as much as possible in the limited space of the water storage cup 31. The heating part 321 extends into the water storage cup 31 and is a core component of the heating function. When the dishwasher is working, the current passes through the heating part 321 to convert the electric energy into heat energy, thereby heating the washing water in the water storage cup 31. The material of the heating part 321 can be a metal material with good electrical conductivity and heat conductivity, such as stainless steel, to ensure efficient heating effect.

[0087] The mounting part 322 connects both ends of the heating part 321 and is used to stably mount the heating part 321 on the inner wall of the water storage cup 31 to avoid displacement due to water flow impact or vibration during dishwasher operation. The mounting part 322 can be made of plastic or metal material through injection molding, stamping or other processes. Its connection with the inner wall of the water storage cup 31 can be clamping, bolt connection, etc. to ensure the stability of the connection.

[0088] The electricity connection part 323 is electrically connected with both ends of the heating part 321 and can be connected with the heating part 321 by welding, which is used to provide electric energy for the heating part 321. The electricity connection part 323 extends out of the water storage cup 31 to facilitate connection with the power system of the dishwasher. The electricity connection part 323 can be made of metal material with good electrical conductivity.

[0089] Further, the heating element 32 also includes a sealing part 324, which abuts between the mounting part 322 and the inner wall of the water storage cup 31. The sealing part 324 can be made of rubber, silicone or other materials with good elasticity and sealing performance. Its function is to prevent the washing water from leaking out of the joint between the mounting part 322 and the inner wall of the water storage cup 31. During the operation of the dishwasher, the water storage cup 31 is full of washing water. If there is no sealing part 324, the washing water may seep out along the gap between the mounting part 322 and the inner wall, which not only causes waste of water resources, but also may cause damage to other parts of the dishwasher.

[0090] In one embodiment, as shown in Figure 6 The first set distance D1 between the heating part 321 and the inner wall of the water storage cup 31 is greater than or equal to 5mm. The first set distance ensures that there is a certain space interval between the heating part 321 and the inner wall of the water storage cup 31, so that the heating part 321 is in a relatively suspended state.

[0091] Specifically, the mounting part 322 can be designed as a support structure with a certain length to fix the heating part 321 at a position with a distance from the inner wall of not less than 5mm. For example, a protrusion or bracket can be provided on the mounting part 322 to form a sufficient gap between the heating part 321 and the inner wall.

[0092] If the distance between the heating element 321 and the inner wall is too small or even if it is in close contact with the inner wall, the heat generated by the heating element 321 will be concentrated at the contact point with the inner wall, easily leading to excessively high local temperatures in that area. Prolonged localized high temperatures may damage the inner wall of the water reservoir 31; for example, a plastic water reservoir 31 may experience deformation or accelerated aging. Maintaining a distance of D1 ≥ 5mm effectively disperses heat, prevents localized overheating of the inner wall, extends the lifespan of the water reservoir 31, and ensures the stability and reliability of the dishwasher.

[0093] In one embodiment, the water cup assembly 30 further includes a first filter 33.

[0094] The first filter element 33 is placed over the opening of the water storage cup 31, covering the heating element 321 inside the water storage cup 31. Exemplarily, the first filter element 33 is planar and has a first filter screen on it, used to initially filter the washing water entering the water storage cup 31, preventing larger residues and debris from entering the water storage cup 31 and avoiding damage to the heating element 321. It also ensures that the water in the water storage cup 31 is relatively clean, which is beneficial for subsequent heating and washing operations.

[0095] The first filter element 33 can be made of materials such as plastic or metal, and is formed by injection molding, stamping or other processes. During installation, the first filter element 33 can be fixed to the opening of the water storage cup 31 by snap-fit ​​or fastening to ensure that it is firmly installed and well sealed, preventing unfiltered washing water from directly entering the water storage cup 31.

[0096] Furthermore, the heating element 321 and the first filter element 33 have a second predetermined distance D2, and D2≥4mm.

[0097] During the process of washing water flowing into the water storage cup 31, the second set distance provides sufficient space for the water flow. The water can flow more smoothly through the filter screen of the first filter element 33 into the water storage cup 31, avoiding obstruction of water flow and affecting water intake efficiency due to the heating element 321 being too close to the first filter element 33. At the same time, the heating element 321 generates heat during operation. If it is too close to the first filter element 33, heat can easily accumulate between them, potentially damaging the first filter element 33 due to overheating; for example, the first filter element 33 made of plastic may deform. Maintaining a distance of D2 ≥ 4mm facilitates heat dissipation, protects the first filter element 33, and extends its service life.

[0098] In one embodiment, the water cup assembly 30 further comprises a second filter 34, which is arranged in the first filter 33. The second filter 34 has a residue collection cavity 3401, which is in communication with the washing inner cavity 100. The heating part 321 is annular and surrounds the outer periphery of the residue collection cavity 3401.

[0099] Exemplarily, the second filter 34 is in a cylindrical shape and can be manufactured by injection molding, welding or other processes to ensure the sealing and structural strength of the residue collection cavity 3401. During installation, the second filter 34 is accurately arranged in the corresponding position of the first filter 33 and is in communication with the washing inner cavity 100. The heating part 321 can be fixed on the outer periphery of the residue collection cavity 3401 by a support, a buckle or other means to form an annular structure.

[0100] The residue collection cavity 3401 of the second filter 34 can further collect and separate the residues in the washing water. The washing water flowing from the washing inner cavity 100 first passes through the primary filtration of the first filter 33 and then is subjected to the secondary filtration of the second filter 34, so that the residues are collected in the residue collection cavity 3401, thereby improving the filtration effect and making the water entering the water storage cup 31 cleaner.

[0101] The heating part 321 surrounds the outer periphery of the residue collection cavity 3401, so that when the water in the water storage cup 31 is heated, the heat can be more uniformly transmitted to the entire water storage cup 31. At the same time, this layout can make full use of the space around the residue collection cavity 3401 and fully utilize the heat energy to improve the heating efficiency.

[0102] Further, the heating part 321 has a third set distance D3 from the outer peripheral wall of the residue collection cavity 3401, and D3≥5mm.

[0103] In this embodiment, if the heating part 321 is too close to the outer peripheral wall of the residue collection cavity 3401, the heat generated by the heating part 321 can cause the temperature in the residue collection cavity 3401 to rise, resulting in the residues drying and caking, which is not conducive to the collection and cleaning of the residues. Maintaining the distance of D3≥5mm can reduce the influence of the heating part 321 on the temperature of the residue collection cavity 3401, so that the residues can more smoothly enter and stay in the residue collection cavity 3401.

[0104] At the same time, the third set distance can provide the heating part 321 with more sufficient contact space with the water in the water storage cup 31, which is conducive to the uniform diffusion of heat in the water. This avoids the problem that the local water temperature is too high due to the heating part 321 being close to the outer peripheral wall of the residue collection cavity 3401, while the water temperature of other parts rises slowly, thereby improving the overall heating uniformity and efficiency.

[0105] Please refer to Figures 7 to 12 , Figure 7A structure diagram of the water cup assembly 30 according to the embodiment is shown in FIG. 1; Figure 8 Another structure diagram of the water cup assembly 30 according to the embodiment is shown in FIG. 2; Figure 9 A structure diagram of the isolation cover 35 according to the embodiment is shown in FIG. 3; Figure 10 An internal structure diagram of the first filter 33 and the second filter 34 according to the embodiment is shown in FIG. 4; Figure 11 An internal structure diagram of the partition 20, the water cup assembly 30, the drainage waterway 40 and the washing waterway 50 according to the embodiment is shown in FIG. 5; Figure 12 Another structure diagram of the partition 20, the water cup assembly 30, the drainage waterway 40 and the washing waterway 50 according to the embodiment is shown in FIG. 6.

[0106] In one embodiment, the water cup assembly 30 further comprises an isolation cover 35 movably arranged in the residue collection cavity 3401. The isolation cover 35 is composed of a top wall and a peripheral wall connected to the peripheral edge of the top wall. The top wall has a first shielding part 351, and the peripheral wall has a residue guide opening 3501. The isolation cover 35 has two different states, i.e., a residue collection position and a residue isolation position.

[0107] When the isolation cover 35 is in the residue collection position, the residue guide opening 3501 is at least partially higher than the top surface of the second filter 34, so that the residue collection cavity 3401 and the washing inner cavity 100 are in communication. During the operation of the dishwasher, the residue-containing washing water in the washing inner cavity 100 can flow into the residue collection cavity 3401 through the residue guide opening 3501, so as to collect the residue.

[0108] When the isolation cover 35 is in the residue isolation position, the peripheral edge of the first shielding part 351 abuts against the cavity wall of the residue collection cavity 3401, so as to separate the washing inner cavity 100 and the residue collection cavity 3401, and prevent the odor generated by the residue in the residue collection cavity 3401 from entering the washing inner cavity 100.

[0109] The isolation cover 35 can be made of light and durable materials such as plastic, and formed by injection molding. In order to ensure that the isolation cover 35 can move in the residue collection cavity 3401, a guide rail or a sliding groove can be arranged on the inner wall of the residue collection cavity 3401, and a sliding block matched with the guide rail or the sliding groove is arranged on the peripheral wall of the isolation cover 35, so that the isolation cover 35 can move along the specified path to the residue collection position and the residue isolation position.

[0110] In the residue collection position, the communicated channel enables the residue to quickly and smoothly enter the residue collection cavity 3401, thereby improving the efficiency of residue collection. For example, during the washing cycle of the dishwasher, a large amount of residue can be collected in time, so as to avoid the accumulation of residue in the washing inner cavity 100 and affect the washing effect.

[0111] In the residue collection position, the blocking function can prevent the residue collected in the residue collection cavity 3401 from flowing back to the washing cavity 100, ensuring the cleanliness of the washing water and improving the washing quality of the tableware. At the same time, the odor generated by the residue in the residue collection cavity 3401 is prevented from entering the washing cavity 100.

[0112] In one embodiment, the peripheral wall of the isolation cover 35 is further provided with a second shielding part 352, which is located below the residue guide opening 3501 and abuts against the cavity wall of the residue collection cavity 3401. When the isolation cover 35 is in the residue collection position, the second shielding part 352 blocks the residue collection cavity 3401 and the water storage cup 31.

[0113] In this embodiment, the blocking of the residue collection cavity 3401 and the water storage cup 31 can prevent the residue from entering the water storage cup 31, avoiding damage to the heating element 32 and other components in the water storage cup 31. For example, the residue may be wound around the heating part 321, affecting the heating efficiency and even causing short circuit and other faults. The provision of the second shielding part 352 effectively avoids such problems.

[0114] At the same time, preventing the residue from entering the water storage cup 31 can maintain the cleanliness of the water in the water storage cup 31, which is beneficial to subsequent heating and washing work, and improves the overall performance and stability of the dishwasher.

[0115] In one embodiment, the water cup assembly 30 further comprises a driving mechanism 34, which is in transmission connection with the isolation cover 35. The driving mechanism 34 drives the isolation cover 35 to move along the height direction of the second filter 34 between the residue collection position and the residue collection position.

[0116] Exemplarily, the driving mechanism 34 comprises a motor 341 and a transmission screw 342. The motor 341 is installed outside the second filter 34, and the transmission screw 342 extends along the height direction of the second filter 34. One end of the transmission screw 342 is connected with the output end of the motor 341, and the other end extends into the residue collection cavity 3401 and is connected with the isolation cover 35.

[0117] The motor 341 is installed outside the second filter 34 by bolts or other fixing methods, ensuring firm installation. The transmission screw 342 is connected with the output end of the motor 341 by a shaft coupling or the like. The end extending into the residue collection cavity 3401 is threadedly connected with the isolation cover 35, ensuring the stability of transmission.

[0118] When the dishwasher control system issues a command, the motor 341 starts to drive the transmission screw 342 to rotate. Since the transmission screw 342 is connected with the isolation cover 35, the rotary motion of the screw is converted into the linear motion of the isolation cover 35 along the height direction of the second filter 34, which can accurately drive the isolation cover 35 to the residue collection position and the residue collection position.

[0119] Please refer to Figure 1 、 Figure 13 and Figure 14 , Figure 13 a partial internal structure diagram of a dishwasher provided by an embodiment of the present application; Figure 14 another partial internal structure diagram of a dishwasher provided by an embodiment of the present application.

[0120] In one embodiment, as shown in Figure 1 and Figure 13 , the inner container 10 is formed with a drying air duct 103, which has a first air inlet 1031 and a first air outlet 1032, and both the first air inlet 1031 and the first air outlet 1032 are in communication with the washing inner cavity 100. The drying air duct 103 serves to provide a specific channel for the circulation of air in the washing inner cavity 100, so as to achieve the drying function of the tableware. The first air inlet 1031 is the entrance of hot air into the drying air duct 103, and the first air outlet 1032 is the exit of hot air back to the washing inner cavity 100 after flowing through the drying air duct 103.

[0121] Exemplarily, the drying air duct 103 can be integrally formed in the manufacturing process of the inner container 10, for example, the air duct structure is directly made inside the inner container 10 by using injection molding process. Alternatively, the air duct component can be made of metal or plastic plate material and then fixed on the inner container 10 by welding, bonding or clamping, etc., to ensure the sealing and structural strength of the air duct.

[0122] In the drying stage of the dishwasher, air circulates in the washing inner cavity 100 through the drying air duct 103. The hot air enters the washing inner cavity 100 from the water storage cup 31, contacts the surface of the tableware, takes away the moisture on the tableware, and then flows to the drying air duct 103 from the first air inlet 1031, and finally flows back to the washing inner cavity 100 from the first air outlet 1032 for re-heating and circulation. The circulating air can accelerate the evaporation of moisture on the surface of the tableware and improve the drying efficiency. Moreover, the arrangement of the drying air duct 103 makes the air flow more orderly, avoiding the disordered flow of air in the washing inner cavity 100, ensuring the uniformity of the drying effect, so that the tableware at each position can be effectively dried.

[0123] Further, the dishwasher further comprises a first air blower 61 located at one end of the drying air duct 103 close to the first air inlet 1031. The first air blower 61 serves to provide power to promote the flow of air in the drying air duct 103.

[0124] The first fan 61 can be fixed at a position close to the first air inlet 1031 of the drying air duct 103 by means of bolts, buckles or the like. The motor 341 of the fan is connected with the control system of the dishwasher, and the speed of the fan can be adjusted through the control system, so as to control the flow speed of the air.

[0125] Further, the first air inlet 1031 is arranged on the top wall of the inner container 10, and the first air outlet 1032 is arranged on the side wall of the inner container 10.

[0126] In this embodiment, the first air inlet 1031 is located on the top wall, which is conducive to sucking in hot air from above the washing cavity 100, because hot air usually rises and gathers at the top. The first air outlet 1032 is located on the side wall, and the hot air blown out from the side wall can better cover the tableware, forming good air convection. Such a layout enables the air to fully contact the tableware, improving the drying effect and efficiency. At the same time, it also avoids blowing hot air directly to a specific area, ensuring the uniformity of drying.

[0127] In one embodiment, as shown in Figure 14 The inner container 10 has a second air inlet 104 and a second air outlet 105, both of which are connected with the washing cavity 100 and the external environment. The second air outlet 105 is provided with a second fan 62, which provides power to promote the exchange of air between the washing cavity 100 and the external environment, thereby discharging humid air and introducing fresh air.

[0128] The second air inlet 104 and the second air outlet 105 can be directly opened on the side wall of the inner container 10, and then the corresponding ventilation duct or ventilation grille is installed to ensure that the air can smoothly enter and exit. The second fan 62 is fixed at the second air outlet 105 by means of bolts or the like, and is connected with the control system to realize the control of its operation.

[0129] During the drying process, the second fan 62 operates to discharge the humid air in the washing cavity 100 to the external environment through the second air outlet 105, while fresh air enters the washing cavity 100 from the second air inlet 104. This air exchange can effectively reduce the humidity in the washing cavity 100 and speed up the drying speed of the tableware. Moreover, the introduction of fresh air can avoid the generation of odor due to the long-term circulation of air in the closed washing cavity 100, maintain the freshness of the air in the washing cavity 100, and improve the use experience.

[0130] Further, the second air inlet 104 and the second air outlet 105 are arranged on the opposite side walls of the inner container 10.

[0131] The arrangement of the two opposite side walls enables air to enter from one side, pass through the entire washing inner cavity 100, and then be discharged from the other side, forming a large range of air convection. In this way, fresh air can fully reach every corner of the washing inner cavity 100, more effectively taking away the moisture on the surface of the tableware, further improving the drying efficiency and uniformity. At the same time, this convection mode also helps to quickly discharge the humid air, keeping the environment in the washing inner cavity 100 dry and clean.

[0132] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
