It should be further understood that the term "comprising" used in the specification of the present application refers to the presence of the features, elements and / or components, but does not exclude the presence or addition of one or more other features, elements, components and / or groups thereof.

The term "and / or" used herein includes all or any unit and all combinations of one or more associated listed items.

[0041] like Figure 1-4 As shown, an embodiment of the present application provides a condensation structure, which is applied to a dishwasher. The condensation structure mainly includes a shell 1, which extends in one direction. The shell 1 has a condensation air duct 11 inside. The condensation air duct 11 includes an air premixing section 111, a plurality of air remixing sections 112 connected in sequence, and a cold air inlet section 113 and a hot air inlet section 114 arranged in parallel; wherein the cold air inlet section 113 and the hot air inlet section 114 are both connected to the air premixing section 111; the air premixing section 111 is connected to a plurality of air remixing sections 112 in sequence; and the air remixing section 112 is a curved structure.

[0042] The positional relationship between the premixing area A of the wind premixing section 111, the reflection area B and the remixing area C of the wind remixing section 112 is as follows: Figure 4 shown.

[0043] In this embodiment, the shell 1 extends in one direction to form a plate-like structure, and the shell 1 is arranged in a vertical direction. A condensation air duct 11 is formed in the shell 1. The cold air introduction section 113 and the hot air introduction section 114 are arranged at the top of the condensation air duct 11, and the air inlet of the cold air introduction section 113 and the air inlet of the hot air introduction section 114 are both located at the top, and the openings can be arranged upward. The hot air introduction section 114 is used to communicate with the inner tank 3, and is used to guide the hot and humid hot air in the inner tank 3 of the dishwasher to flow into the condensation air duct 11. The cold air introduction section 113 is used to guide the external cold air to flow into the condensation air duct 11. The air outlet of the condensation air duct 11 is located at the bottom. The wind after the cold air and the hot air are mixed flows from top to bottom as a whole.

[0044] The cold air introduction section 113 and the hot air introduction section 114 extend downward and converge to form an air premixing section 111 to achieve preliminary mixing of cold air and hot air. The premixed air flows into the air remixing section 112 in sequence to increase the mixing time and improve the condensation effect.

[0045] After the heat preservation in the high-temperature rinsing stage is over, the hot and humid air from the inner cavity of the dishwasher and the cold air from the outside flow into the condensation structure provided in the embodiment of the present application. After being pre-mixed and re-mixed multiple times, the condensation effect is achieved. In this way, there is no need to let the hot and humid air inside the cavity stand still to condense, thereby shortening the washing time and reducing the standing (condensation) time of the high-temperature rinsing stage. At the same time, the temperature of water vapor discharged to the outside of the dishwasher can be reduced, thereby avoiding scalding users and water accumulation caused by the discharged water vapor, thereby improving the user experience.

[0046] like Figure 1 As shown, as an optional embodiment, the cross-sectional area of ​​the wind premixing section 111 gradually decreases along the flow direction.

[0047] Based on the above embodiments, in this embodiment, the flow direction is the flow direction of the condensation air duct 11. The wind premixing section 111 gradually narrows inward along the flow direction. More specifically, the two side wall structures corresponding to the width of the wind premixing section 111 are close to each other and extend to form a wind premixing section 111 with a gradually decreasing cross-sectional area, so that the cold air and the hot air are more concentrated, which can improve the mixing effect and condensation effect of the cold air and the hot air.

[0048] like Figure 1As shown, as an optional embodiment, the wind remixing section 112 is roughly L-shaped, and the wind remixing section 112 includes a wind reflection section 1121 and a wind mixing section 1122 that are connected; the length of the wind reflection section 1121 is greater than the length of the wind mixing section 1122; the wind inlet end of the wind reflection section 1121 serves as the wind inlet end of the wind remixing section 112, and the wind outlet end of the wind mixing section 1122 serves as the wind outlet end of the wind remixing section 112; the wind reflection section 1121 of the first wind remixing section 112 is connected to the wind premixing section 111, and the wind reflection sections 1121 of the remaining wind remixing sections 112 are connected to the wind mixing section 112 of the previous wind remixing section 112. The section 1122 connected to the wind remixing section 112 is roughly L-shaped, and the wind remixing section 112 includes a connected wind reflection section 1121 and a wind mixing section 1122; the length of the wind reflection section 1121 is greater than the length of the wind mixing section 1122; the wind inlet end of the wind reflection section 1121 serves as the wind inlet end of the wind remixing section 112, and the wind outlet end of the wind mixing section 1122 serves as the wind outlet end of the wind remixing section 112; the wind reflection section 1121 of the first wind remixing section 112 is connected to the wind premixing section 111, and the wind reflection sections 1121 of the remaining wind remixing sections 112 are connected to the wind mixing section 1122 of the previous wind remixing section 112.

[0049] Based on the above-mentioned embodiments, in this embodiment, the wind remixing section 112 is approximately an L-shaped structure, and the "long side" of the L-shaped structure is the wind reflection section 1121, so as to guide the reflected wind to the wind mixing section 1122 for mixing as much as possible. The more times the wind is reflected, the stronger the guiding property of the wind reflection section 1121, the stronger the wind gathering property, and the better the mixing effect; the "short side" of the L-shaped structure is the wind mixing section 1122, and the wind flowing through the wind reflection section 1121 changes its flow direction at least once after colliding with the side wall, until it flows to the wind mixing section 1122 for gathering and mixing. The wind reflection section 1121 is the air inlet end of the wind remixing section 112, and the wind mixing section 1122 is the air outlet end of the wind remixing section 112. Multiple wind remixing sections 112 are connected end to end in sequence to achieve multiple remixing of the two winds, which can improve the mixing effect and condensation effect of cold wind and hot wind. The more wind remixing sections 112 there are, the better the condensation effect.

[0050] like Figure 1 As shown, as an optional embodiment, a plurality of air remixing sections 112 are arranged in a stacked manner.

[0051] Based on the above-mentioned embodiments, in this embodiment, the "L"-shaped structure of the first wind remixing section 112 is horizontally placed, and the air inlet of the first wind remixing section 112 is arranged upward to communicate with the wind premixing section 111; the wind remixing section 112 of the first wind remixing section 112 extends downward; the "L"-shaped structure of the next wind remixing section 112 is also horizontally placed, and the wind reflection section 1121 of the next wind remixing section 112 is connected with the wind remixing section 112 of the previous wind remixing section 112; the wind remixing section 112 of the next wind remixing section 112 extends downward; the above-mentioned arrangement is repeated until the last wind remixing section 112, so as to realize the stacking arrangement of multiple wind remixing sections 112, so as to achieve the purpose of saving space. In addition, all wind remixing sections 112 are tilted downward to realize the condensed water flowing downward along the condensation air duct 11, so as to guide the flow of condensed water.

[0052] like Figure 1 As shown, as an optional embodiment, the condensation structure also includes a water collecting section 115, which is curved and extended. The water collecting section 115 is connected to the last wind mixing section 1122 correspondingly, and the lowest curved portion in the water collecting section 115 is used to receive dripping condensed water.

[0053] Based on the above embodiments, in this embodiment, the water collecting section 115 may be U-shaped or V-shaped, and the water collecting section 115 includes at least one curved portion. The water collecting section 115 is located below the air outlet of the last air remixing section 112 to receive the condensed water obtained after multiple mixing and condensation, so as to achieve the purpose of collecting and draining.

[0054] like Figure 1 and 2 As shown, as an optional embodiment, the condensation structure further includes a drain pipe 2, one end of which is connected to the lowest point of the water collecting section 115, and the other end of which is used to communicate with the inner tank 3 of the dishwasher.

[0055] By adopting the above solution, the condensed water can be led back to the inner tank 3. When the water in the inner tank 3 reaches a preset drainage volume, the water in the inner tank 3 is discharged from the inner tank 3, which is convenient for the user to pour out and dispose of.

[0056] like Figure 1-7 As shown, based on the same inventive concept, the embodiment of the present application provides a dishwasher, which mainly includes an inner tank 3, a cold air duct 4, a connecting piece 5, a hot air blower 6, a cold air blower 7 and a condensation structure of any one of the above embodiments. The cold air duct 4 is arranged on one side of the inner tank 3; the connecting piece 5 has a hot air channel and a cold air channel; the hot air channel is connected to the inner tank 3, and the cold air channel is connected to the cold air duct 4; the hot air blower 6 is arranged in the hot air channel; the cold air blower 7 is arranged in the cold air channel; the condensation structure is connected to the connecting piece 5, the cold air introduction section 113 of the condensation structure is connected to the cold air channel, and the hot air introduction section 114 of the condensation structure is connected to the hot air channel.

[0057] Based on the above embodiments, in this embodiment, the inner tank 3 is a cubic structure, which serves as a container for accommodating tableware. The cold air duct 4 is arranged outside the inner tank 3. The connecting piece 5 is used to connect the inner tank 3, the cold air duct 4 and the condensation structure, and pass the hot air in the inner tank 3 into the condensation channel, and the cold air outside the dishwasher into the condensation channel. The hot air blower 6 provides power for the hot air flow. The cold air blower 7 provides power for the cold air flow.

[0058] The hot air blower 6 draws hot air from the inner tank 3, and the cold air blower 7 inhales air from the outside. The two winds flow through the connecting piece 5 and into the condensation channel. The two winds are initially mixed and condensed, which promotes the condensation of water vapor in the gas of the inner tank 3 and is introduced into the inner tank 3. Then the mixed air passes through the condensation channel and is discharged to the outside of the inner tank 3. In this way, there is no need to let the hot and humid air inside the cavity stand still to condense, thereby shortening the washing time, reducing the standing (condensation) time of the high-temperature rinsing stage, and reducing the water vapor discharged outside the dishwasher, avoiding scalding users and water accumulation due to the external water vapor, thereby improving the user experience.

[0059] like Figure 3-7 As shown, as an optional embodiment, the dishwasher also includes an upper rear cross piece 8, which is a long strip structure. The upper rear cross piece 8 has an air guide channel 82 that penetrates along the width direction. The air inlet end of the air guide channel 82 is connected to the outside, the air outlet end of the air guide channel 82 is connected to the air inlet end of the cold air duct 4, and the air outlet end of the cold air duct 4 is connected to the air inlet end of the cold air channel.

[0060] Based on the above embodiments, in this embodiment, the upper rear cross member 8 includes an upper rear cross member body 81, which is a long strip structure and is arranged horizontally. An air guide channel 82 is arranged on the upper rear cross member body 81, and the air guide channel 82 extends in the front-to-back direction, and the air inlet end and the air outlet end of the air guide channel 82 are both rectangular holes. The air guide channel 82 is connected to the cold air duct 4 to transport the condensation on one side of the dishwasher (for example, the rear side, the air inlet end of the air guide channel 82 is arranged backward) to the condensation air duct 11. Optionally, the air guide channel 82, the cold air duct 4 and the cold air channel are welded and sealed or plugged and sealed.

[0061] like Figure 7 As shown, as an optional implementation, a filter 9 is provided at the air inlet end of the air guide channel 82 .

[0062] Based on the foregoing embodiments, in this embodiment, the filter 9 is in a grid shape, forming a blocking structure, which can prevent cockroaches and the like from entering and breeding.

[0063] As an optional embodiment, a hot air outlet is provided on the top wall of the inner liner 3; a cold air duct 4 is arranged on the top of the inner liner 3; a condensation structure is arranged on the outside of the side wall of the inner liner 3; and the connecting piece 5 is a bent structure, and the connecting piece 5 is arranged at the connection between the top wall of the inner liner 3 and the side wall of the inner liner 3.

[0064] Based on the above embodiments, in this embodiment, the inner tank 3 is arranged on a horizontal plane. The upper rear cross bar 8 is connected to the cold air duct 4 and both are arranged on the top of the inner tank 3, and the cold air duct 4 is arranged close to the edge; the condensation structure is arranged vertically and close to the cold air duct 4. The connecting piece 5 is provided with a hot air inlet, a hot air outlet, a cold air inlet and a cold air outlet. The hot air inlet is connected to the hot air outlet on the top wall of the inner tank 3, and the cold air inlet is connected to the air outlet of the cold air duct 4. The hot air outlet and the cold air outlet are connected to the condensation structure accordingly. This arrangement can realize the rationalization of the design of the two wind paths, improve the space utilization rate, obtain cold air from the design direction (such as the rear side of the dishwasher) and obtain hot air from the inner tank 3 at the same time, and introduce it into the condensation structure nearby to realize condensation.

[0065] By applying the embodiments of the present application, at least the following beneficial effects can be achieved:

[0066] After the heat preservation in the high-temperature rinsing stage is over, the hot and humid air from the inner cavity of the dishwasher and the cold air from the outside flow into the condensation structure provided in the embodiment of the present application. After being pre-mixed and re-mixed multiple times, the condensation effect is achieved. In this way, there is no need to let the hot and humid air inside the cavity stand still to condense, thereby shortening the washing time and reducing the standing (condensation) time of the high-temperature rinsing stage. At the same time, the temperature of water vapor discharged to the outside of the dishwasher can be reduced, thereby avoiding scalding users and water accumulation caused by the discharged water vapor, thereby improving the user experience.
