Description

Technical Field

[0001] The present invention relates to the field of dishwashers, and in particular to an internal circulation drying device and a dishwasher. Background Art

[0002] Existing internal circulation drying devices typically feature a fan and heater, consisting of left and right housings. These two housings are fastened together to form a mounting cavity, which secures the fan, heater, and other components. However, this structural design presents significant drawbacks: Firstly, repairs are extremely inconvenient in the event of a heater or fan failure; secondly, since the housing housing the heater requires more expensive, high-temperature-resistant materials, this integrated design of the left and right housings results in higher costs. Summary of the Invention

[0003] Based on this, it is necessary to provide an internal circulation drying device and a dishwasher to address the problem of inconvenient maintenance operations.

[0004] An internal circulation drying device, comprising:

[0005] A condensation shell, wherein the condensation shell is provided with a condensation channel, and the condensation shell is provided with a first air inlet and a first air outlet communicating with the condensation channel, wherein the first air inlet is used to communicate with the inner tank;

[0006] a heating shell assembly, the heating shell assembly being detachably mounted on the condensing shell, the heating shell assembly being provided with a heating channel, and the heating shell assembly being provided with a second air inlet and a second air outlet communicating with the heating channel;

[0007] a fan assembly, the fan assembly being disposed on the condensing shell and / or the heating shell assembly, the fan assembly being in communication with the first air outlet and the second air inlet, respectively;

[0008] The air outlet shell is detachably mounted on the heating shell assembly, the air outlet shell is provided with an air outlet channel, the air outlet shell is provided with a third air inlet and a third air outlet connected to the air outlet channel, the third air inlet is connected to the second air outlet, and the third air outlet is used to connect to the inner tank.

[0009] The internal circulation drying device disclosed in this application has a condensation channel provided on the condensation shell that is connected to a first air inlet and a first air outlet. When the hot and humid air from the inner tank enters the condensation channel through the first air inlet, the hot and humid air comes into contact with the cold wall surface of the condensation shell within the channel, and the water vapor in the air is cooled and liquefied, thereby effectively removing moisture from the air. This design allows the moisture generated during the drying process to be condensed and discharged in a timely manner, improving drying efficiency and ensuring the drying effect. The heating shell assembly is detachably mounted on the condensation shell, and the heating channel inside it is connected to other components through the second air inlet and the second air outlet. When the fan assembly is operating, the dry air after condensation and dehumidification is sucked in from the first air outlet and enters the heating channel for heating. The detachable design not only facilitates maintenance and repair of the heating shell assembly, but also allows the heating shell assembly to be flexibly replaced or adjusted according to different drying needs to meet the drying temperature requirements of different materials. The outlet shell is detachably mounted on the heating shell assembly, and the outlet channel inside it is connected to the second air outlet through the third air inlet, which is used to connect to the inner tank. The heated, dry air enters the air outlet channel through the third air inlet and is then delivered to the inner container through the third air outlet to dry the material. The detachable air outlet housing is easy to install and remove, allowing for quick removal when cleaning or maintenance of the inner container is required.

[0010] In one embodiment, the condensation shell includes a condensation outer shell and a condensation element, the condensation outer shell is provided with the condensation channel, the condensation outer shell is provided with the first air inlet and the first air outlet, and the condensation element is arranged on the condensation outer shell and located in the condensation channel. The condensation shell consists of a condensation outer shell and a condensation element, and the condensation element is arranged in the condensation channel of the condensation outer shell. When the hot and humid air from the inner tank enters the channel through the first air inlet, the condensation element increases the contact area between the hot and humid air and the cold wall surface, so that the water vapor is more fully cooled and liquefied. This structural design effectively improves the dehumidification amount per unit time and shortens the drying cycle, and is particularly suitable for drying scenarios with high-humidity materials. The layout of the condensation element in the condensation channel can guide the hot and humid air to flow evenly and avoid dead corners in the channel.

[0011] In one embodiment, the condensation channel includes a condensation air inlet section, a condensation section, a liquid guide section and an air outlet section, the condensation air inlet section, the condensation section, the liquid guide section and the air outlet section are connected in sequence, the condensation air inlet section is connected to the first air inlet, the air outlet section is connected to the first air outlet, and the condensation elements are distributed in the condensation section and / or the liquid guide section. By dividing the condensation channel into a condensation air inlet section, a condensation section, a liquid guide section and an air outlet section, each section is connected in sequence. The condensation air inlet section is connected to the first air inlet, which can guide the hot and humid air to enter the channel smoothly and reduce the air flow impact loss; the condensation elements are centrally arranged in the condensation section and / or the liquid guide section to form an exclusive heat exchange area, so that the air can be fully condensed and dehumidified here; the liquid guide section receives the water liquefied by the condensation section, and through the inclined slope or guide groove design, the condensate is quickly guided to the collection device to avoid liquid retention affecting air circulation.

[0012] In one embodiment, the liquid guide section is provided with a water outlet, and the air outlet housing is provided with a water inlet, the water outlet being connected to the water inlet. The air outlet housing is configured to communicate with the inner container so that condensed water in the condensation channel can flow back into the inner container. The connection between the air outlet housing and the inner container allows generated condensed water to be promptly fed into the inner container for recycling, while preventing accumulation of condensed water and clogging the condensation channel, thereby improving the condensation effect.

[0013] In one embodiment, a portion of the condensing shell is concave, and the concave portion is the air outlet section. The concave portion of the condensing shell forms the air outlet section, which can increase the flow area of the channel.

[0014] In one embodiment, a limiting protrusion is provided on one of the condensing housing and the fan assembly, and a limiting opening is provided on the other of the condensing housing and the fan assembly, and the limiting protrusion and the limiting opening are adapted to each other. By providing the limiting protrusion and the limiting opening to the condensing housing and the fan assembly, respectively, the adapted design of the two can form precise positioning during installation. When the limiting protrusion is embedded in the limiting opening, it can effectively prevent the fan assembly from lateral displacement or angular deviation relative to the condensing housing, ensure that the air inlet of the fan assembly is accurately docked with the first air outlet of the condensing channel, and reduce the problem of airflow leakage caused by installation errors.

[0015] In one embodiment, a portion of the condenser housing is disposed opposite the fan assembly, and the portion of the condenser housing opposite the fan assembly is raised toward a side away from the fan assembly. By raising the portion of the condenser housing opposite the fan assembly, the area of this area can be increased, thereby minimizing obstructions to the fan assembly during operation.

[0016] In one embodiment, the first air outlet is located between the highest and lowest levels of the condensation channel. This design prevents the air outlet from being submerged in condensate when located at the lowest point of the channel, while also preventing increased air flow resistance due to a location that is too high.

[0017] In one embodiment, the condensing shell, the heating shell assembly and the air outlet shell are arranged in sequence from top to bottom. The condensing shell, the heating shell assembly and the air outlet shell are arranged in sequence from top to bottom to form a vertical air flow circulation channel. The hot and humid air from the inner tank enters the condensation channel from the first air inlet of the condensing shell, is discharged from the first air outlet after condensation and dehumidification, and is then sucked into the heating channel of the heating shell assembly by the fan assembly below. The heated dry air then enters the air outlet shell at the bottom and is sent back to the inner tank. This top-down layout allows the airflow to follow the natural gravity flow direction of "condensation and dehumidification → heating → drying", reducing the resistance loss caused by horizontal turning.

[0018] In one embodiment, the first air inlet and the first air outlet are located at either end of the condensation channel. This allows the hot and humid air to flow through the channel, ensuring that the hot and humid air can fully pass through the condensation section and come into contact with the condensing element.

[0019] In one embodiment, the second air inlet is located at one end of the heating channel. By having the second air inlet located at one end of the heating channel, the condensed and dehumidified air enters the heating area from a single direction, forming a stable unidirectional flow.

[0020] In one embodiment, the device further includes a baffle assembly that is rotatably mounted on the air outlet housing and located at the third air inlet, and that can open or close the third air inlet. The baffle assembly is rotatably mounted at the third air inlet of the air outlet housing, and the air inlet can be opened or closed by adjusting the rotation angle. When the drying process needs to be started, the baffle assembly is rotated to the open position, allowing hot air from the heating channel to flow smoothly into the air outlet channel. When the drying process is stopped, the baffle assembly is rotated to the closed position to prevent the hot and humid air in the liner from flowing back into the heating shell assembly.

[0021] In one embodiment, the heating shell assembly includes a first shell, a second shell and a heating assembly, the first shell is arranged on the second shell, the first shell and the second shell cooperate to form the heating channel, and the heating assembly is arranged on the first shell. The heating channel is formed by the structure in which the first shell is arranged on the second shell. This modular design facilitates assembly and disassembly and simplifies the equipment maintenance process. When it is necessary to clean or replace the internal components of the heating channel, the first shell and the second shell can be directly disassembled to improve the convenience of operation. By setting the heating assembly on the first shell, the heating area can be precisely controlled according to the flow direction or heating requirements of the medium in the channel.

[0022] In one embodiment, on the second shell, the first shell and the second shell cooperate to form the second air inlet and the second air outlet.

[0023] In one embodiment, the first shell and the second shell are connected by a snap connection or a screw connection.

[0024] In one embodiment, a baffle assembly is further included, which is rotatably mounted on the heating shell assembly and located at the second air outlet, and the baffle assembly can open or close the second air outlet. The baffle assembly is rotatably mounted at the second air outlet of the heating shell assembly, and the air outlet can be opened or closed by rotating. When the drying process needs to be started, the baffle assembly is rotated to the open position, and the hot air in the heating channel can flow smoothly into the air outlet housing; when the machine is shut down, the baffle assembly is rotated to the closed position, which can effectively prevent the hot and humid air in the air outlet housing and the inner tank from flowing back to the heating channel, thereby preventing the heating component from being shortened in service life due to contact with moisture.

[0025] In one embodiment, the baffle assembly includes a shaft portion, a baffle, and a gravity portion. The shaft portion is rotatably mounted on the heating housing assembly, and the baffle and gravity portion are both mounted on the shaft portion. The shaft portion has at least a first position and a second position. When the fan assembly is operating, the shaft portion is in the first position, opening the second air outlet. When the fan assembly is deactivated, the gravity portion drives the shaft portion to rotate from the first position to the second position, whereupon the baffle blocks the second air outlet. The baffle assembly achieves interlocked control with the fan assembly through the cooperation of the shaft portion, the baffle, and the gravity portion. When the fan assembly is operating, the power generated by the airflow drives the shaft portion to the first position, keeping the second air outlet open and ensuring smooth discharge of hot air from the heating channel. When the fan assembly is deactivated, the gravity portion, by its own weight, drives the shaft portion to rotate to the second position, at which point the baffle automatically blocks the second air outlet. This allows for automatic opening and closing of the air outlet without the need for an additional drive device, thereby enhancing the device's intelligence and ease of use.

[0026] A second aspect of the present application discloses a dishwasher, comprising:

[0027] The above-mentioned internal circulation drying device.

[0028] The dishwasher disclosed in this application is equipped with the aforementioned internal circulation drying device. Through the cooperation of the condensing housing, heating housing assembly, and other components, it can quickly reduce the surface moisture of dishware. The condensing channel's dehumidifying effect on the hot and humid air, combined with the heated air circulation in the heating channel, can quickly reduce the surface moisture content of the dishware, ensuring that the dishware is dry and free of water droplets when removed, improving user convenience.

[0057] The fan assembly 3 is provided on the condensing shell 1 and / or the heating shell assembly 2, and the fan assembly 3 is respectively connected to the first air outlet 103 and the second air inlet 202;

[0058] The air outlet shell 4 is detachably mounted on the heating shell assembly 2. The air outlet shell 4 is provided with an air outlet channel 401. The air outlet shell 4 is provided with a third air inlet 402 and a third air outlet 403 connected to the air outlet channel 401. The third air inlet 402 is connected to the second air outlet 203. The third air outlet 403 is used to connect to the inner tank.

[0059] The internal circulation drying device disclosed in the present application has a condensation channel 101 provided on the condensation shell 1 that is connected to the first air inlet 102 and the first air outlet 103. When the hot and humid air from the inner tank enters the condensation channel 101 through the first air inlet 102, the hot and humid air contacts the cold wall surface of the condensation shell 1 in the channel, and the water vapor therein is cooled and liquefied, thereby effectively removing moisture from the air. This design enables the moisture generated during the drying process to be condensed and discharged in a timely manner, thereby improving the drying efficiency and ensuring the drying effect. The heating shell assembly 2 is detachably provided on the condensation shell 1, and the heating channel 201 inside it is connected to other components through the second air inlet 202 and the second air outlet 203. When the fan assembly 3 is working, the dry air after condensation and dehumidification is sucked in from the first air outlet 103 and enters the heating channel 201 for heating. The detachable design not only facilitates the maintenance and inspection of the heating shell assembly 2, but also allows the heating shell assembly 2 to be flexibly replaced or adjusted according to different drying needs to meet the drying temperature requirements of different materials. The air outlet housing 4 is removably mounted on the heating shell assembly 2. Its internal air outlet duct 401 communicates with the second air outlet 203 via the third air inlet 402. The third air outlet 403 is connected to the inner container. Heated, dry air enters the air outlet duct 401 through the third air inlet 402 and is then delivered to the inner container through the third air outlet 403, drying the material. The removable air outlet housing 4 facilitates installation and removal, allowing for quick and easy removal when cleaning or maintenance is required.

[0060] like Figure 7As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that: the condensing shell 1 includes a condensing outer shell 11 and a condensing element 12, the condensing outer shell 11 is provided with a condensing channel 101, the condensing outer shell 11 is provided with a first air inlet 102 and a first air outlet 103, and the condensing element 12 is arranged on the condensing outer shell 11 and located in the condensing channel 101. The condensing shell 1 consists of the condensing outer shell 11 and the condensing element 12, and the condensing element 12 is arranged in the condensing channel 101 of the condensing outer shell 11. When the hot and humid air from the inner tank enters the channel through the first air inlet 102, the condensing element 12 increases the contact area between the hot and humid air and the cold wall surface, allowing the water vapor to be more fully cooled and liquefied. This structural design effectively improves the dehumidification capacity per unit time and shortens the drying cycle, and is particularly suitable for drying high-humidity materials. The layout of the condensing element 12 in the condensing channel 101 can guide the hot and humid air to flow evenly and avoid the formation of airflow dead corners in the channel.

[0061] like Figure 7 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the condensation channel 101 includes a condensation air inlet section 1011, a condensation section 1012, a liquid guide section 1013, and an air outlet section 1014; the condensation air inlet section 1011, the condensation section 1012, the liquid guide section 1013, and the air outlet section 1014 are sequentially connected; the condensation air inlet section 1011 is connected to the first air inlet 102, and the air outlet section 1014 is connected to the first air outlet 103; and the condensation element 12 is distributed in the condensation section 1012 and / or the liquid guide section 1013. By dividing the condensation channel 101 into the condensation air inlet section 1011, the condensation section 1012, the liquid guide section 1013, and the air outlet section 1014, each section is sequentially connected. The condensing air inlet section 1011 is connected to the first air inlet 102, which can guide the hot and humid air to enter the channel smoothly and reduce the air flow impact loss; the condensing section 1012 and / or the liquid guide section 1013 are centrally arranged with the condensing element 12 to form an exclusive heat exchange area, so that the air can be fully condensed and dehumidified here; the liquid guide section 1013 receives the liquefied water from the condensing section 1012, and through the inclined slope or guide groove design, quickly guides the condensate to the collection device to avoid liquid retention affecting air circulation.

[0062] like Figure 7 As shown, in addition to the features of the above embodiment, this embodiment further defines: the liquid guide section 1013 is provided with a water outlet, the air outlet housing 4 is provided with a water inlet, the water outlet and the water inlet are connected, and the air outlet housing 4 is used to communicate with the inner tank so that condensed water in the condensation channel 101 can flow back into the inner tank. The connection between the air outlet housing 4 and the inner tank allows the generated condensed water to be promptly input into the inner tank for recycling, while preventing the accumulation of condensed water and clogging the condensation channel 101, thereby improving the condensation effect.

[0063] like Figure 7As shown, in addition to the features of the above embodiment, this embodiment further defines that: the condensing housing 11 is partially recessed, and the recessed portion is the air outlet section 1014. The recessed portion of the condensing housing 11 forms the air outlet section 1014, which can increase the flow area of the channel.

[0064] In addition to the features of the above-mentioned embodiment, this embodiment further defines that: a limiting protrusion is provided on one of the condensing housing 11 and the fan assembly 3, and a limiting opening is provided on the other of the condensing housing 11 and the fan assembly 3, and the limiting protrusion and the limiting opening are adapted to each other. By providing the limiting protrusion and the limiting opening to the condensing housing 11 and the fan assembly 3, respectively, the adapted design of the two can form precise positioning during installation. When the limiting protrusion is embedded in the limiting opening, it can effectively prevent the fan assembly 3 from lateral displacement or angular deviation relative to the condensing housing 11, ensuring that the air inlet of the fan assembly 3 is accurately docked with the first air outlet 103 of the condensing channel 101, and reducing the problem of airflow leakage caused by installation errors.

[0065] like Figure 5 As shown, in addition to the features of the above embodiment, this embodiment further provides that: a portion of the condensing housing 11 is disposed opposite the fan assembly 3, and the portion of the condensing housing 11 opposite the fan assembly 3 is raised toward a side away from the fan assembly 3. By raising the portion of the condensing housing 11 opposite the fan assembly 3, the area of this region can be increased, thereby minimizing obstructions to the fan assembly 3 during operation.

[0066] like Figure 6 and Figure 7 As shown, in addition to the features of the above embodiment, this embodiment further defines that the first air outlet 103 is located between the highest and lowest levels of the condensation channel 101. The first air outlet 103 is located between the highest and lowest levels of the condensation channel 101. This design prevents the air outlet from being submerged in condensate when it is at the lowest point of the channel, and also prevents increased air flow resistance due to a location that is too high.

[0067] like Figure 1 and Figure 2 As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that: the condensing shell 1, the heating shell assembly 2 and the air outlet shell 4 are arranged in sequence from top to bottom. The condensing shell 1, the heating shell assembly 2 and the air outlet shell 4 are arranged in sequence from top to bottom to form a vertical air flow circulation channel. The hot and humid air from the inner tank enters the condensation channel 101 from the first air inlet 102 of the condensing shell 1, is discharged from the first air outlet 103 after condensation and dehumidification, and is then sucked into the heating channel 201 of the heating shell assembly 2 by the fan assembly 3 below. The heated dry air then enters the air outlet shell 4 at the bottom and is sent back to the inner tank. This top-down layout enables the airflow to follow the natural gravity flow direction of "condensation and dehumidification → heating → drying", reducing the resistance loss caused by horizontal turning.

[0068] like Figure 3 As shown, in addition to the features of the above embodiment, this embodiment further defines: the first air inlet 102 and the first air outlet 103 are respectively located at both ends of the condensation channel 101. By having the first air inlet 102 and the first air outlet 103 located at both ends of the condensation channel 101, the hot and humid air forms a through-flow in the channel, ensuring that the hot and humid air can completely pass through the condensation section 1012 and fully contact the condensation element 12.

[0069] like Figure 10 and Figure 11 As shown, in addition to the features of the above embodiment, this embodiment further defines that the second air inlet 202 is located at one end of the heating channel 201. By having the second air inlet 202 located at one end of the heating channel 201, the air after condensation and dehumidification enters the heating area from a single direction, forming a stable unidirectional flow.

[0070] In addition to the features of the above-mentioned embodiment, this embodiment is further defined as follows: it also includes a baffle assembly 5, which is rotatably set on the air outlet housing 4 and located at the third air inlet 402, and the baffle assembly 5 can open or close the third air inlet 402. By rotating the baffle assembly 5 at the third air inlet 402 of the air outlet housing 4, the air outlet can be opened or closed by the rotation angle. When it is necessary to start the drying process, the baffle assembly 5 is rotated to the open position, and the hot air from the heating channel 201 can smoothly enter the air outlet channel 401; when the machine is shut down, the baffle assembly 5 is rotated to the closed position to prevent the hot and humid air in the inner tank from flowing back to the heating shell assembly 2.

[0071] like Figure 9 、 Figure 10 and Figure 11 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the heating shell assembly 2 includes a first shell 21, a second shell 22 and a heating assembly 23, the first shell 21 is arranged on the second shell 22, the first shell 21 and the second shell 22 cooperate to form a heating channel 201, and the heating assembly 23 is arranged on the first shell 21. The heating channel 201 is formed by the structure in which the first shell 21 is arranged on the second shell 22. This modular design facilitates assembly and disassembly and simplifies the equipment maintenance process. When it is necessary to clean or replace the internal components of the heating channel, the first shell 21 and the second shell 22 can be directly disassembled to improve the convenience of operation. By arranging the heating assembly 23 on the first shell 21, the heating area can be precisely controlled according to the flow direction or heating requirements of the medium in the channel.

[0072] like Figure 11As shown, in addition to the features of the above embodiment, this embodiment further defines that: on the second shell 22 , the first shell 21 and the second shell 22 cooperate to form a second air inlet 202 and a second air outlet 203 .

[0073] In addition to the features of the above embodiment, this embodiment further defines that the first shell 21 and the second shell 22 are connected by snap-fit connection or screw connection.

[0074] like Figure 11 and Figure 12 As shown, in addition to the features of the above-mentioned embodiment, this embodiment is further defined as follows: it also includes a baffle assembly 5, the baffle assembly 5 is rotatably set on the heating shell assembly 2 and is located at the second air outlet 203, and the baffle assembly 5 can open or close the second air outlet 203. The baffle assembly 5 is rotatably set at the second air outlet 203 of the heating shell assembly 2, and the air outlet can be opened or closed by a rotating action. When it is necessary to start the drying process, the baffle assembly 5 is rotated to the open position, and the hot air in the heating channel 201 can flow smoothly into the air outlet shell 4; when shutting down, the baffle assembly 5 is rotated to the closed position, which can effectively prevent the hot and humid air in the air outlet shell 4 and the inner tank from flowing back to the heating channel 201, thereby preventing the heating assembly 23 from being shortened in service life due to contact with moisture.

[0075] like Figure 11 and Figure 12 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the baffle assembly 5 includes a rotating shaft portion 51, a baffle 52, and a gravity portion 53. The rotating shaft portion 51 is rotatably mounted on the heating shell assembly 2. The baffle 52 and the gravity portion 53 are both mounted on the rotating shaft portion 51. The rotating shaft portion 51 has at least a first position and a second position. When the fan assembly 3 is operating, the rotating shaft portion 51 is located in the first position, and the second air outlet 203 is open. When the fan assembly 3 stops operating, the gravity portion 53 drives the rotating shaft portion 51 to rotate from the first position to the second position. When the rotating shaft portion 51 is in the second position, the baffle 52 blocks the second air outlet 203. The baffle assembly 5 achieves linkage control with the fan assembly 3 through the cooperation of the rotating shaft portion 51, the baffle 52, and the gravity portion 53. When the fan assembly 3 is working, the power generated by the airflow drives the rotating shaft portion 51 to the first position, so that the second air outlet 203 remains open, ensuring that the hot air in the heating channel 201 is discharged smoothly; when the fan assembly 3 stops working, the gravity portion 53 relies on its own gravity to drive the rotating shaft portion 51 to rotate to the second position. At this time, the baffle 52 automatically blocks the second air outlet 203, and the air outlet can be automatically opened and closed without an additional driving device, thereby improving the intelligence and ease of use of the equipment.
