Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, and in particular to a condensation device and a dishwasher. Background Art

[0002] Dishwashers are typically equipped with a condenser unit, which is used to quickly remove the steam generated during operation, improving the drying efficiency of the dishes inside the dishwasher and reducing the overall energy consumption. However, existing dishwasher condenser units suffer from problems such as complex structures, long required air ducts, low condensation efficiency, and long cooling times. Furthermore, many condenser units also fail to exhaust sufficiently dry air, resulting in excessive condensation at the exhaust vent, negatively impacting the user experience. Utility Model Content

[0003] Therefore, it is necessary to provide a condenser and dishwasher to address the problems of complex structure of dishwasher condenser devices and insufficient drying of exhaust air.

[0004] A condensation device includes: a first housing assembly having a confluence channel formed therein, one end of which is provided with an air inlet and an air intake, the air intake being used to communicate with a washing chamber; a second housing assembly disposed on the first housing assembly, the second housing assembly having a condensate channel and a condensate return chamber, the condensate channel communicating with the confluence channel, the condensate return chamber being able to communicate with the washing chamber; and a third housing disposed on the second housing assembly, the third housing having a water storage chamber and an exhaust port, the water storage chamber communicating with the condensate channel, and the exhaust port communicating with the water storage chamber.

[0005] The first aspect of this application discloses a condensation device. A first housing assembly has an air inlet communicating with the outside air and an air inlet communicating with a washing chamber. The air inlet and air inlet respectively introduce dry air and steam from the washing chamber into a confluence channel, where they mix to form condensate. The first housing assembly allows for the independent introduction of both dry and humid air through dual channels, and the mixing of the dry and humid air within the confluence channel makes the overall structure of the condensation device more compact and simple. A condensate channel communicates with the confluence channel. The condensate formed in the confluence channel is guided to a condensate return chamber and then returns to the washing chamber to condense the steam in the washing chamber. Steam that is not completely condensed in the confluence channel undergoes a second stage of condensation as it flows through the condensate channel. The resulting condensate flows along the inner wall of the condensate channel into a water storage chamber in the third housing. This makes the gas discharged from the exhaust port drier and prevents condensate from flowing out of the machine. Furthermore, the condensate in the water storage chamber can also condense subsequently flowing steam, further improving the condensation effect of the condensation device.

[0006] In one embodiment, a fan assembly is further included, comprising a first fan disposed at the air inlet of the first housing assembly, with the air inlet and outlet of the first fan respectively opposite to the air inlet and the confluence channel; and / or, the fan assembly includes a second fan disposed at the air outlet of the third housing, with the air inlet and outlet of the second fan respectively opposite to the water storage chamber and the air outlet. By installing the first fan at the air inlet, the first fan can introduce dry outside air into the confluence channel, mixing it with the humid air in the confluence channel to form condensate, thereby enabling the condensing device to condense steam. By installing the second fan at the air outlet, the second fan can discharge the dry air in the condensate channel, creating a negative pressure in the confluence channel and the condensate channel. Steam in the washing chamber will enter the confluence channel due to the negative pressure and mix with the dry air in the confluence channel to form condensate.

[0007] In one embodiment, the first housing assembly is provided with a plurality of condensation protrusions, which are densely distributed on the first housing assembly and located within the confluence channel. By providing a plurality of densely arranged condensation protrusions within the confluence channel, the contact area between the dry and humid air and the confluence channel is increased, the rate of condensation formation is accelerated, and the condensation effect is further improved.

[0008] In one embodiment, a backflow prevention baffle is further included. The first housing assembly is provided with an air inlet duct, and a connecting protrusion is provided on the first housing assembly. The connecting protrusion is located inside the air inlet duct. One end of the backflow prevention baffle is rotatably disposed on the connecting protrusion. The backflow prevention baffle has at least a first state and a second state. When the backflow prevention baffle is located away from the connecting protrusion, it is separated from the inner wall of the air inlet duct, so that the air inlet is connected to the air inlet duct. When the backflow prevention baffle is in the second state, the end of the backflow prevention baffle away from the connecting protrusion is attached to the inner wall of the air inlet duct, and the backflow prevention baffle separates the air inlet from the air inlet duct. A backflow baffle is rotatably mounted on a connecting protrusion on the first housing assembly. The backflow baffle rotates relative to the connecting protrusion as the first fan starts and stops, switching between a first state and a second state. When the first fan starts, the end of the backflow baffle away from the connecting protrusion is blown up, separating from the inner wall of the lower end of the air inlet duct. At this time, the backflow baffle is in the first state, allowing the air output from the first fan to enter the air inlet duct. When the first fan stops working, the backflow baffle switches from the first state to the second state. The end of the backflow baffle away from the connecting protrusion hangs down naturally, abutting against the inner wall of the lower end of the air inlet duct, separating the air inlet from the air inlet duct. This simple structure, where the backflow baffle switches states with the start and stop of the first fan, simplifies the structural design of the condensation unit while effectively protecting the first fan and extending the equipment's service life.

[0009] In one embodiment, the first housing assembly includes a middle body, a bottom cover, and an upper shell. The bottom cover is disposed on the middle body and partially adapted to form an air inlet duct. The upper shell is disposed on the side of the middle body away from the bottom cover, and partially adapted to form an air intake duct and a confluence channel. The air inlet duct and the air intake duct are connected to the same end of the confluence channel. By partially adapting the bottom cover to form the air inlet duct, and partially adapting the upper shell to form the air intake duct and the confluence channel, and by connecting the air inlet duct and the air intake duct to the same end of the confluence channel, dry air and humid air can respectively enter the confluence channel from the air inlet duct and the air intake duct and mix to form condensate. This structural design, utilizing the first housing assembly to form a dual-airflow system that simultaneously introduces dry air and steam, makes the overall structure of the condensing device more compact and simple, ensuring sufficient condensation effect while simplifying the installation process.

[0010] In one embodiment, the intermediate main body has an air inlet communicating with the air inlet duct, and the upper shell has an air inlet communicating with the air intake duct. By providing an air inlet communicating with the air intake duct on the intermediate main body and an air inlet communicating with the air intake duct on the upper shell, the orientation of the air inlet communicating with the outside atmosphere is consistent with the orientation of the air inlet communicating with the washing chamber, enabling the condensation device to adapt to dishwashers with different layouts.

[0011] In one embodiment, the bottom cover has a first air inlet communicating with the air inlet duct. By providing a first air inlet communicating with the air inlet duct on the bottom cover, the first air inlet is connected to the outside atmosphere, and the direction of the first air inlet communicating with the outside atmosphere is opposite to the direction of the air inlet communicating with the washing chamber. By setting the direction of the air inlet of the condenser to communicate with the outside air in the same as or opposite to the direction of the air inlet communicating with the washing chamber, the condenser can be adapted to dishwasher structures with different layouts, thus broadening its application.

[0012] In one embodiment, the second housing assembly includes a second housing body, a guide rib, and a housing cover. The housing cover is disposed on the second housing body, and the housing cover and the second housing body are adapted to form a condensate channel and a condensate return chamber. The guide rib is disposed on the second housing body and is horizontally positioned within the condensate channel, with a portion of the guide rib extending into the condensate return chamber. The guide rib has an air vent. By providing a guide rib within the condensate channel, when condensate formed in the confluence channel flows into the condensate channel, the guide rib can guide the condensate to the condensate return chamber. The condensate in the condensate return chamber can then flow back into the washing chamber to condense the steam in the washing chamber, further improving the condensation effect of the condensing device. The air vent on the guide rib allows the condensate channel to be unobstructed. Uncondensed steam will pass through the air vent and reach the second condensation section for further condensation. The condensate formed at this time will flow along the inner wall of the condensate channel into the water storage chamber, making the discharged gas drier and preventing liquid from flowing out of the machine body, which would affect the user experience.

[0013] In one embodiment, the second housing body is connected to the intermediate body, and the housing cover is connected to the upper housing. The upper housing and the intermediate body are fitted together to form a confluence channel, and the housing cover and the second housing body are fitted together to form a condensate channel. The second housing body and the housing cover are respectively connected to the intermediate body and the upper housing, thus connecting the confluence channel and the condensate channel to form two condensation sections, improving the condensation effect of the condensation device.

[0014] In one embodiment, the second housing body is integrally formed with the intermediate main body, and the housing cover is integrally formed with the upper housing. By integrally forming the second housing body with the intermediate main body and the housing cover with the upper housing, and by using the structural design of the guide ribs to divide the air duct into a confluence channel and a condensate channel, better condensation effect can be ensured. At the same time, the overall structure of the condensing device is simpler, and the assembly process of the condensing device is simplified.

[0015] In one embodiment, there are multiple guide ribs, spaced apart on the second housing body. Each guide rib has an air passage in the middle, and the multiple air passages are arranged opposite each other to allow the condensate water channel to be unobstructed. By setting multiple layers of guide ribs, the condensate water in the confluence channel is guided to the condensate water return chamber, so that the condensate water is recovered as much as possible. In addition, the multiple air passages on the multiple guide ribs are arranged opposite each other, so that the condensate water channel is unobstructed, and the unobstructed condensate water channel reduces the load on the second fan.

[0016] In one embodiment, the second housing assembly has a return hole communicating with the condensate return chamber, which is used to communicate with the outside. By providing the return hole on the second housing assembly and connecting it to the washing chamber via a pipe, condensate in the condensate return chamber can flow back into the washing chamber through the pipe. The condensate returning to the washing chamber can further condense the steam in the washing chamber, accelerating the condensation process and allowing the tableware in the washing chamber to dry quickly.

[0017] A dishwasher includes: a housing assembly having a mounting cavity therein; a washing tub disposed on the housing assembly and located within the mounting cavity, the washing tub having a washing chamber; and a condensing device as described above, the condensing device being disposed on the washing tub and located within the mounting cavity.

[0018] The second aspect of this application discloses a dishwasher that uses a condenser device that is simultaneously connected to both outside air and the washing chamber of the inner tub. This allows the condenser device to draw in dry outside air and steam from the washing chamber into a confluence channel to mix and form condensate, achieving the purpose of condensation. During the washing process, the washing chamber is filled with a large amount of steam. The condenser device's dual-inlet design, which simultaneously draws in both dry and humid air, makes the overall structure more compact, resulting in better condensation and higher efficiency. A condensate channel is provided to allow uncondensed steam to continue condensing, further improving the condensation effect. The compact structure of the condenser device enables rapid and effective steam discharge and cooling, accelerating the drying of tableware while simultaneously cooling the machine body quickly.

[0033] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0035] The condensing device and dishwasher of some embodiments of this application are described below with reference to the accompanying drawings.

[0036] Example 1, as Figures 1 to 7 As shown, this embodiment discloses a condensation device, including: a first housing assembly 1, in which a confluence channel 101 is formed, and one end of the confluence channel 101 is respectively provided with an air inlet 102 and an air inlet 103, the air inlet 103 being used to communicate with a washing chamber; a second housing assembly 2, which is disposed on the first housing assembly 1, and is provided with a condensate water channel 201 and a condensate water return chamber 202, the condensate water channel 201 being connected to the confluence channel 101, and the condensate water return chamber 202 being able to communicate with the washing chamber; and a third housing 3, which is disposed on the second housing assembly 2, and is provided with a water storage chamber 301 and an exhaust port 302, the water storage chamber 301 being connected to the condensate water channel 201, and the exhaust port 302 being connected to the water storage chamber 301.

[0037] The first aspect of this application discloses a condensation device. An air inlet 102 on the first housing assembly 1 communicates with the outside air, and an air inlet 103 communicates with the washing chamber. The air inlet 102 and air inlet 103 respectively introduce dry air and steam from the washing chamber into a confluence channel 101, where they mix to form condensate. The first housing assembly 1 allows for the independent introduction of both dry and humid air through dual channels, and the mixing of dry and humid air within the confluence channel 101 makes the overall structure of the condensation device more compact and simple. A condensate channel 201 communicates with the confluence channel 101. The condensate formed in the confluence channel 101 is guided to a condensate return chamber 202 and then returned to the washing chamber, condensing the steam in the washing chamber. Steam that is not completely condensed in the manifold 101 can undergo a second stage of condensation when it flows through the condensate channel 201. The condensate formed at this time will flow along the inner wall of the condensate channel 201 into the water storage chamber 301 of the third housing 3, which can make the gas discharged from the exhaust port 302 drier and prevent the condensate from flowing out of the machine body. In addition, the condensate in the water storage chamber 301 can also condense the steam that flows through it later, further improving the condensation effect of the condensation device.

[0038] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further includes: a fan assembly 4, which includes a first fan 41 disposed at the air inlet 102 of the first housing assembly 1, with the air inlet and outlet of the first fan 41 respectively opposite to the air inlet 102 and the confluence channel 101; and / or, the fan assembly 4 includes a second fan 42 disposed at the air outlet 302 of the third housing 3, with the air inlet and outlet of the second fan 42 respectively opposite to the water storage chamber 301 and the air outlet 302. By installing the first fan 41 at the air inlet 102, the first fan 41 can introduce dry outside air into the confluence channel 101, mix it with the humid air in the confluence channel 101 to form condensate, thereby realizing the function of the condensing device in condensing steam. A second fan 42 is installed at the exhaust vent 302. The second fan 42 can exhaust the dry air in the condensate channel 201, so that a negative pressure is formed in the manifold channel 101 and the condensate channel 201. The steam in the washing chamber will enter the manifold channel 101 due to the negative pressure and mix with the dry air in the manifold channel 101 to form condensate.

[0039] like Figure 2 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first housing assembly 1 is provided with a plurality of condensation protrusions, which are densely distributed in the first housing assembly 1 and located within the confluence channel 101. By providing a plurality of densely arranged condensation protrusions within the confluence channel 101, the contact area between dry and humid air and the confluence channel 101 is increased, the rate of condensation formation is accelerated, and the condensation effect is further improved.

[0040] like Figure 3 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further includes: a backflow prevention baffle 5; the first housing assembly 1 is provided with an air inlet duct 104; the first housing assembly 1 is provided with a connecting protrusion located inside the air inlet duct 104; one end of the backflow prevention baffle 5 is rotatably disposed on the connecting protrusion; the backflow prevention baffle 5 has at least a first state and a second state; when the backflow prevention baffle 5 is in the first state, the end of the backflow prevention baffle 5 away from the connecting protrusion is separated from the inner wall of the air inlet duct 104, so that the air inlet 102 is connected to the air inlet duct 104; when the backflow prevention baffle 5 is in the second state, the end of the backflow prevention baffle 5 away from the connecting protrusion is attached to the inner wall of the air inlet duct 104, and the backflow prevention baffle 5 separates the air inlet 102 from the air inlet duct 104. The anti-backflow baffle 5 rotates relative to the connecting protrusion on the first housing assembly 1 as the first fan 41 starts and stops, thus switching between a first state and a second state. When the first fan 41 starts, the end of the anti-backflow baffle 5 away from the connecting protrusion is blown up and separated from the inner wall of the lower end of the air inlet duct 104. At this time, the anti-backflow baffle 5 is in the first state, allowing the air output by the first fan 41 to enter the air inlet duct 104. When the first fan stops working, the anti-backflow baffle 5 switches from the first state to the second state, and the end of the anti-backflow baffle 5 away from the connecting protrusion hangs down naturally, abutting against the inner wall of the lower end of the air inlet duct 104, separating the air inlet 102 from the air inlet duct 104. The simple structure of the anti-backflow baffle 5 switching states with the start and stop of the first fan 41 makes the structural design of the condensation device simpler, while effectively protecting the first fan 41 and extending the service life of the equipment.

[0041] like Figure 3 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further defines: the first housing assembly 1 includes an intermediate body 11, a bottom cover 12, and an upper shell 13. The bottom cover 12 is disposed on the intermediate body 11 and partially adapted to form an air inlet duct 104. The upper shell 13 is disposed on the side of the intermediate body 11 away from the bottom cover 12. The upper shell 13 is partially adapted to form an air inlet duct 105 and a confluence channel 101. The air inlet duct 104 and the air inlet duct 105 are connected to the same end of the confluence channel 101. By partially adapting the bottom cover 12 to form the air inlet duct 104, and partially adapting the upper shell 13 to form the air inlet duct 105 and the confluence channel 101, and by connecting the air inlet duct 104 and the air inlet duct 105 to the same end of the confluence channel 101, dry air and humid air can respectively enter the confluence channel 101 from the air inlet duct 104 and the air inlet duct 105 to mix and form condensate. The structural design of using the first housing component 1 to form a dual air duct to simultaneously introduce dry air and steam makes the overall structure of the condensing device more compact and simple, ensuring a good condensing effect while simplifying the installation process of the condensing device.

[0042] like Figure 2 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: an air inlet 102 communicating with the air inlet duct 104 is provided on the intermediate main body 11, and an air inlet 103 communicating with the air inlet duct 105 is provided on the upper shell 13. By providing an air inlet 102 communicating with the air inlet duct 104 on the intermediate main body 11 and an air inlet 103 communicating with the air inlet duct 105 on the upper shell 13, the orientation of the air inlet 102 communicating with the outside atmosphere is consistent with the orientation of the air inlet 103 communicating with the washing chamber, so that the condensation device can be adapted to dishwashers with different layouts.

[0043] like Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a first air inlet 106 communicating with the air inlet duct 104 is provided on the bottom cover 12. By providing the first air inlet 106 communicating with the air inlet duct 104 on the bottom cover 12, the first air inlet 106 is connected to the outside atmosphere. At this time, the direction in which the first air inlet 106 communicates with the outside atmosphere is opposite to the direction in which the air inlet 103 communicates with the washing chamber. By setting the direction in which the air inlet of the condensing device communicates with the outside air to be the same as or opposite to the direction in which the air inlet 103 communicates with the washing chamber, the condensing device can be adapted to dishwasher structures with different layouts, thus expanding its application.

[0044] like Figure 1 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further defines: the second housing assembly 2 includes a second housing body 21, a guide rib 22, and a housing cover 23. The housing cover 23 is disposed on the second housing body 21, and the housing cover 23 and the second housing body 21 are adapted to form a condensate channel 201 and a condensate return cavity 202. The guide rib 22 is disposed on the second housing body 21 and is horizontally disposed within the condensate channel 201. A portion of the guide rib 22 extends into the condensate return cavity 202, and an air outlet 203 is provided on the guide rib 22. By providing the guide rib 22 within the condensate channel 201, when the condensate formed in the confluence channel 101 flows into the condensate channel 201, the guide rib 22 can guide the condensate to the condensate return cavity 202. The condensate in the condensate return cavity 202 can flow back into the washing chamber, condensing the steam in the washing chamber and further improving the condensation effect of the condensing device. The guide rib 22 is provided with an air vent 203 to allow the condensate water channel 201 to pass through. Uncondensed steam will pass through the air vent 203 and reach the second condensation section to continue condensing. The condensate formed at this time will flow into the water storage chamber 301 along the inner wall of the condensate water channel 201, making the exhaust gas drier and preventing liquid from flowing out of the machine body, which would affect the user experience.

[0045] like Figure 1 and Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the second housing body 21 is connected to the intermediate body 11, and the housing cover 23 is connected to the upper housing 13. The upper housing 13 and the intermediate body 11 are adapted to form a confluence channel 101, and the housing cover 23 and the second housing body 21 are adapted to form a condensate channel 201. The second housing body 21 and the housing cover 23 are respectively connected to the intermediate body 11 and the upper housing 13, so that the confluence channel 101 and the condensate channel 201 are connected to form two condensation sections, improving the condensation effect of the condensation device.

[0046] like Figure 6 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the second housing body 21 is integrally formed with the intermediate body 11, and the housing cover 23 is integrally formed with the upper shell 13. By integrally forming the second housing body 21 with the intermediate body 11 and the housing cover 23 with the upper shell 13, and by using the structural design of the guide rib 22 to divide the air duct into a confluence channel 101 and a condensate channel 201, better condensation effect can be ensured. At the same time, the overall structure of the condensing device is made simpler, and the assembly process of the condensing device is simplified.

[0047] like Figure 2 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of guide ribs 22 is multiple, and the multiple guide ribs 22 are spaced apart on the second housing body 21. Each guide rib 22 has an air passage 203 in the middle, and the multiple air passages 203 are arranged opposite each other to make the condensate channel 201 unobstructed. By setting multiple layers of guide ribs 22, the condensate in the confluence channel 101 is guided to the condensate return cavity 202, so that the condensate is recovered as much as possible. In addition, the multiple air passages 203 on the multiple guide ribs 22 are arranged opposite each other to make the condensate channel 201 unobstructed, and the unobstructed condensate channel 201 puts less load on the second fan 42.

[0048] like Figure 1 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the second housing assembly 2 is provided with a return hole 204 communicating with the condensate return chamber 202, and the return hole 204 is used to communicate with the outside. By providing the return hole 204 on the second housing assembly 2 communicating with the condensate return chamber 202, and by providing a pipe fitting to connect the return hole 204 to the washing chamber, the condensate in the condensate return chamber 202 can flow back into the washing chamber from the return hole 204 through the pipe fitting. The condensate returning into the washing chamber can further condense the steam in the washing chamber, further accelerating the steam condensation speed and enabling the tableware in the washing chamber to dry quickly.

[0049] Example 2, as Figures 1 to 7 As shown, this embodiment discloses a dishwasher, including: a housing assembly with an installation cavity inside; a washing inner tub disposed on the housing assembly and located within the installation cavity, the washing inner tub having a washing chamber; and a condensing device 100 as described above, disposed on the washing inner tub and located within the installation cavity.

[0050] The second aspect of this application discloses a dishwasher in which a condensing device 100 is simultaneously connected to both outside air and the washing chamber of the inner tub. This allows the condensing device 100 to introduce dry outside air and steam from the washing chamber into a confluence channel 101, where they mix to form condensate, achieving the purpose of condensation. During the washing process, the washing chamber is filled with a large amount of steam. The dual-inlet design of the condensing device 100, which simultaneously introduces both dry and humid air, makes the overall structure of the condensing device 100 more compact, resulting in better condensation and higher efficiency. A condensate channel 201 is provided to allow uncondensed steam to continue condensing, further improving the condensation effect of the condensing device 100. The compact structure of the condensing device 100 enables rapid and effective steam discharge and cooling, accelerating the drying speed of tableware while simultaneously cooling the machine body quickly.

[0051] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
