Description

Technical Field

[0001] This utility model relates to the field of dishwashers, and in particular to an internal circulation drying device and a dishwasher. Background Technology

[0002] Existing internal circulation drying devices typically include a fan and a heater, and the drying unit comprises left and right housings. The two housings are fastened together to form a mounting cavity, which then secures components such as the fan and heater within this cavity. However, this design has significant drawbacks: firstly, maintenance is extremely inconvenient when the heater or fan malfunctions; secondly, the integrated design of the left and right housings results in higher costs because the housing for the heater requires more expensive high-temperature resistant materials. Utility Model Content

[0003] Therefore, it is necessary to provide an internal circulation drying device and dishwasher to address the problem of inconvenient maintenance and operation.

[0004] An internal circulation drying device, comprising:

[0005] A condenser housing, wherein the condenser housing is provided with a condensation channel, and the condenser housing has 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 liner;

[0006] A heating shell assembly is detachably mounted on the condenser shell. The heating shell assembly is provided with a heating channel and has a second air inlet and a second air outlet communicating with the heating channel.

[0007] A fan assembly is disposed on the condenser housing and / or the heating housing assembly, and the fan assembly is connected to the first air outlet and the second air inlet respectively.

[0008] An air outlet housing is detachably mounted on the heating shell assembly. The air outlet housing has an air outlet channel and a third air inlet and a third air outlet that communicate with the air outlet channel. The third air inlet communicates with the second air outlet, and the third air outlet communicates with the inner liner.

[0009] The internal circulation drying device disclosed in this application has a condensation channel on the condenser shell connected to a first air inlet and a first air outlet. When hot, humid air from the inner tank enters the condensation channel through the first air inlet, the hot, humid air comes into contact with the cold wall surface of the condenser shell within the channel, causing the water vapor in the air to liquefy upon cooling, 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 drying effect. The heating shell assembly is detachably mounted on the condenser shell, and its internal heating channel is connected to other components through a second air inlet and a second air outlet. When the fan assembly is working, the dried air, after condensation and dehumidification, is drawn in from the first air outlet and enters the heating channel for heating. The detachable design not only facilitates the maintenance and repair of the heating shell assembly but also allows for flexible replacement or adjustment of the heating shell assembly according to different drying needs, adapting to the drying temperature requirements of different materials. The air outlet shell is detachably mounted on the heating shell assembly, and its internal air outlet channel is connected to the second air outlet through a third air inlet. The third air outlet is used to connect to the inner tank. The heated, dry air enters the air outlet channel through the third air inlet and then is sent into the inner liner through the third air outlet to dry the material. The detachable air outlet housing is easy to install and remove. When the inner liner needs to be cleaned or maintained, the air outlet housing can be quickly removed, making operation convenient.

[0010] In one embodiment, the condensing shell includes a condensing outer shell and a condensing element. The condensing outer shell is provided with the condensing channel, and has a first air inlet and a first air outlet. The condensing element is disposed on the condensing outer shell and located within the condensing channel. The condensing shell consists of a condensing outer shell and a condensing element, with the condensing element disposed within the condensing channel of the condensing outer shell. When humid and hot air from the inner liner enters the channel through the first air inlet, the condensing element increases the contact area between the humid and hot air and the cold wall surface, allowing water vapor to liquefy more fully upon cooling. This structural design effectively increases the dehumidification rate per unit time and shortens the drying cycle, making it particularly suitable for drying high-humidity materials. The layout of the condensing element within the condensing channel guides the humid and hot air to flow evenly, avoiding dead airflow zones within the channel.

[0011] In one embodiment, the condensation channel includes a condensation inlet section, a condensation section, a liquid guide section, and an air outlet section. These sections are sequentially connected. The condensation inlet section is connected to the first air inlet, and the air outlet section is connected to the first air outlet. The condensing components are distributed in the condensation section and / or the liquid guide section. By dividing the condensation channel into these sections, each sequentially connected, the condensation inlet section connects to the first air inlet, guiding humid and hot air smoothly into the channel and reducing airflow impact loss. The condensation section and / or the liquid guide section centrally arrange condensing components, forming a dedicated heat exchange area where the air is fully condensed and dehumidified. The liquid guide section receives the liquefied water from the condensation section, and through an inclined slope or guide channel design, quickly guides the condensate to a collection device, preventing liquid stagnation from affecting airflow.

[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 and the water inlet are connected, and the air outlet housing is used to connect with the inner liner to allow condensate in the condensation channel to flow back into the inner liner. This connection between the air outlet housing and the inner liner allows the generated condensate to be promptly returned to the inner liner for recycling, while also preventing condensate from accumulating and clogging the condensation channel, thus improving the condensation effect.

[0013] In one embodiment, a portion of the condenser housing is recessed, and this recessed area forms the air outlet section. This partial recess in the condenser housing to form the air outlet section allows for a larger flow area in the channel.

[0014] In one embodiment, a limiting protrusion is provided on one of the condenser housing and the fan assembly, and a limiting port is provided on the other of the condenser housing and the fan assembly. The limiting protrusion and the limiting port are adapted to each other. The design of the limiting protrusion and the limiting port on the condenser housing and the fan assembly, respectively, and their compatibility, allows for precise positioning during installation. When the limiting protrusion is embedded in the limiting port, it effectively prevents lateral displacement or angular deviation of the fan assembly relative to the condenser housing, ensuring precise alignment between the air inlet of the fan assembly and the first air outlet of the condenser channel, reducing airflow leakage problems caused by installation errors.

[0015] In one embodiment, a portion of the condenser housing is positioned opposite the fan assembly, with the portion of the condenser housing facing the fan assembly protruding towards a side away from the fan assembly. This protrusion of the portion of the condenser housing facing the fan assembly allows for a larger area, resulting in less obstruction to the fan assembly during operation.

[0016] In one embodiment, the first air outlet is located between the highest and lowest horizontal positions of the condensation channel. Positioning the first air outlet between the highest and lowest horizontal positions of the condensation channel prevents it from being submerged in condensate when at the lowest point of the channel, while also preventing increased airflow resistance due to an excessively high position.

[0017] In one embodiment, the condenser housing, the heating housing assembly, and the air outlet housing are arranged sequentially from top to bottom. This arrangement forms a vertical airflow circulation channel. Moist, hot air from the inner liner enters the condenser channel through the first air inlet of the condenser housing, is dehumidified by condensation, and is then discharged from the first air outlet. Subsequently, the air is drawn into the heating channel of the heating housing assembly by the fan assembly below, and the heated, dry air then enters the bottom air outlet housing and is returned to the inner liner. This top-down layout ensures that the airflow follows the natural gravity flow direction of "condensation and dehumidification → heating → drying," reducing resistance losses caused by horizontal turning.

[0018] In one embodiment, the first air inlet and the first air outlet are located at opposite ends of the condensation channel. By positioning the first air inlet and the first air outlet at opposite ends of the condensation channel, humid and hot air flows continuously within the channel, ensuring that the humid and hot air can pass completely through the condensation section and make full contact with the condenser components.

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

[0020] In one embodiment, a baffle assembly is further included. This baffle assembly is rotatably mounted on the air outlet housing and located at the third air inlet. The baffle assembly can open or close the third air inlet. By rotating the baffle assembly at the third air inlet of the air outlet housing, the air outlet can be opened or closed. When the drying process needs to be started, the baffle assembly rotates to the open position, allowing hot air from the heating channel to smoothly enter the air outlet channel. When the machine is stopped, the baffle assembly rotates to the closed position to prevent hot and humid air 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 component. The first shell is disposed on the second shell. The first shell and the second shell cooperate to form the heating channel, and the heating component is disposed on the first shell. Through the structure in which the first shell is disposed on the second shell, the heating channel is formed. This modular design facilitates assembly and disassembly, and can simplify 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, improving the operation convenience. By disposing the heating component on the first shell, the heating area can be accurately controlled according to the flow direction of the medium in the channel or the heating requirement.

[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 snap connection or screw connection.

[0024] In one embodiment, a baffle assembly is further included. The baffle assembly is rotatably disposed on the heating shell assembly and is located at the second air outlet. The baffle assembly can open or close the second air outlet. The baffle assembly is rotatably disposed at the second air outlet of the heating shell assembly, and the opening or closing of the air outlet can be realized through a rotational movement. When it is necessary to start the drying process, the baffle assembly rotates to the open position, and the hot air in the heating channel can smoothly flow into the air outlet shell; when the machine stops, the baffle assembly rotates to the closed position, which can effectively prevent the humid hot air in the air outlet shell and the inner liner from flowing back to the heating channel, and avoid shortening the service life of the heating component due to contact with moisture.

[0025] In one embodiment, the baffle assembly includes a rotating shaft portion, a baffle, and a gravity portion. The rotating shaft portion is rotatably disposed on the heating shell assembly. The baffle and the gravity portion are both disposed on the rotating shaft portion. The rotating shaft portion has at least a first position and a second position. When the fan assembly works, the rotating shaft portion is located at the first position, and the second air outlet is opened. When the fan assembly stops working, the gravity portion drives the rotating shaft portion to rotate from the first position to the second position. When the rotating shaft portion is located at the second position, the baffle blocks the second air outlet. The baffle assembly realizes the linkage control with the fan assembly through the cooperation of the rotating shaft portion, the baffle, and the gravity portion. When the fan assembly works, the power generated by the air flow drives the rotating shaft portion to be located at the first position, keeping the second air outlet open, ensuring the smooth discharge of the hot air in the heating channel; when the fan assembly stops working, the gravity portion drives the rotating shaft portion to rotate to the second position by relying on its own gravity. At this time, the baffle automatically blocks the second air outlet, and the automatic opening and closing of the air outlet can be realized without an additional driving device, improving the intelligent level and use convenience of the equipment.

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

[0027] The aforementioned internal circulation drying device.

[0028] The dishwasher disclosed in this application is equipped with the aforementioned internal circulation drying device. Through the cooperation of components such as the condenser shell and the heating shell assembly, it can quickly reduce the surface humidity of tableware. The dehumidifying effect of the condenser channel on the hot and humid air, combined with the hot air circulation in the heating channel, can quickly reduce the surface moisture content of the tableware to a minimum, ensuring that the tableware is dry and free of water droplets when it is removed, thus improving ease of use.

[0050] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0051] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0052] The following describes some embodiments of the internal circulation drying apparatus and dishwasher of the present invention with reference to the accompanying drawings.

[0053] Example 1

[0054] like Figures 1 to 15 As shown, this embodiment discloses an internal circulation drying device, including:

[0055] The condenser housing 1 is provided with a condensation channel 101. The condenser housing 1 has a first air inlet 102 and a first air outlet 103 that are connected to the condensation channel 101. The first air inlet 102 is used to communicate with the inner liner.

[0056] Heating shell assembly 2 is detachably mounted on condenser shell 1. Heating shell assembly 2 is provided with heating channel 201 and has a second air inlet 202 and a second air outlet 203 communicating with heating channel 201.

[0057] Fan assembly 3 is mounted on condenser shell 1 and / or heating shell assembly 2, and fan assembly 3 is connected to the first air outlet 103 and the second air inlet 202 respectively.

[0058] The air outlet housing 4 is detachably mounted on the heating shell assembly 2. The air outlet housing 4 is provided with an air outlet channel 401. The air outlet housing 4 has a third air inlet 402 and a third air outlet 403 that are 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 with the inner liner.

[0059] The internal circulation drying device disclosed in this application has a condensation channel 101 in the condensation shell 1 connected to a first air inlet 102 and a first air outlet 103. When hot and humid air from the inner tank enters the condensation channel 101 through the first air inlet 102, the hot and humid air comes into contact with the cold wall surface of the condensation shell 1 within the channel, and the water vapor in it liquefies upon cooling, 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 drying effect. The heating shell assembly 2 is detachably mounted on the condensation shell 1, and its internal heating channel 201 is connected to other components through a second air inlet 202 and a second air outlet 203. When the fan assembly 3 is working, the dried air after condensation and dehumidification is drawn in from the first air outlet 103 and enters the heating channel 201 for heating. The detachable design not only facilitates the maintenance and repair of the heating shell assembly 2, but also allows for flexible replacement or adjustment of the heating shell assembly 2 according to different drying needs, to adapt to the drying temperature requirements of different materials. The air outlet housing 4 is detachably mounted on the heating shell assembly 2. Its internal air outlet channel 401 connects to the second air outlet 203 via a third air inlet 402. The third air outlet 403 connects to the inner liner. Heated dry air enters the air outlet channel 401 through the third air inlet 402 and is then sent into the inner liner from the third air outlet 403 to dry the material. The detachable air outlet housing 4 facilitates installation and disassembly. When cleaning or maintaining the inner liner is required, the air outlet housing 4 can be quickly removed, making operation convenient.

[0060] like Figure 7As shown, in addition to the features of the above embodiments, this embodiment further defines: the condenser shell 1 includes a condenser outer shell 11 and a condenser component 12. The condenser outer shell 11 is provided with a condensation channel 101, and the condenser outer shell 11 has a first air inlet 102 and a first air outlet 103. The condenser component 12 is disposed on the condenser outer shell 11 and located within the condensation channel 101. The condenser shell 1 is composed of the condenser outer shell 11 and the condenser component 12, and the condenser component 12 is disposed within the condensation channel 101 of the condenser outer shell 11. When the humid and hot air from the inner liner enters the channel through the first air inlet 102, the condenser component 12 increases the contact area between the humid and hot air and the cold wall surface, allowing water vapor to be liquefied more fully upon cooling. This structural design effectively improves the dehumidification capacity per unit time and shortens the drying cycle, making it particularly suitable for drying high-humidity materials. The layout of the condenser component 12 within the condensation channel 101 can guide the humid and hot air to flow evenly, avoiding dead airflow corners within the channel.

[0061] like Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further defines: 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, condensation section 1012, liquid guide section 1013, and 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. The condensing 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, condensation section 1012, liquid guide section 1013, and air outlet section 1014, each section is sequentially connected. The condenser air inlet section 1011 is connected to the first air inlet 102, which can guide the hot and humid air into the channel smoothly and reduce the airflow impact loss. The condenser section 1012 and / or the liquid guide section 1013 are arranged with condenser 12 in a concentrated manner to form a dedicated heat exchange area, so that the air can be fully condensed and dehumidified here. The liquid guide section 1013 receives the water liquefied in the condenser section 1012, and through the inclined slope or guide channel design, the condensate is quickly guided to the collection device to avoid liquid stagnation affecting air circulation.

[0062] like Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: 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 connect with the inner liner so that the condensate in the condensation channel 101 can flow back into the inner liner. The connection between the air outlet housing 4 and the inner liner allows the generated condensate to be promptly input into the inner liner for recycling, while preventing condensate from accumulating and clogging the condensation channel 101, thus improving the condensation effect.

[0063] like Figure 7As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a portion of the condenser housing 11 is recessed, and the recessed area forms the air outlet section 1014. The partial recess of the condenser housing 11 to form the air outlet section 1014 can increase the flow area of ​​the channel.

[0064] In addition to the features of the above embodiments, this embodiment further specifies that: one of the condenser housing 11 and the fan assembly 3 is provided with a limiting protrusion, and the other of the condenser housing 11 and the fan assembly 3 is provided with a limiting port, and the limiting protrusion and the limiting port are adapted to each other. The design of the limiting protrusion and the limiting port respectively on the condenser housing 11 and the fan assembly 3, and their compatibility, allows for precise positioning during installation. When the limiting protrusion is embedded in the limiting port, it effectively prevents lateral displacement or angular deviation of the fan assembly 3 relative to the condenser housing 11, ensuring precise alignment between the air inlet of the fan assembly 3 and the first air outlet 103 of the condenser channel 101, reducing airflow leakage problems caused by installation errors.

[0065] like Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a portion of the condenser housing 11 is disposed opposite to the fan assembly 3, and the portion of the condenser housing 11 opposite to the fan assembly 3 protrudes toward the side away from the fan assembly 3. By protruding the portion of the condenser housing 11 opposite to the fan assembly 3, the area of ​​this region can be increased. The fan assembly 3 experiences fewer obstacles during operation.

[0066] like Figure 6 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the first air outlet 103 is located between the highest and lowest horizontal positions of the condensation channel 101. The first air outlet 103 is positioned between the highest and lowest horizontal positions of the condensation channel 101. This design prevents the air outlet from being submerged by condensate when it is at the lowest point of the channel, and also prevents increased airflow resistance due to an excessively high position.

[0067] like Figure 1 and Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the condenser shell 1, the heating shell assembly 2, and the air outlet shell 4 are arranged sequentially from top to bottom. The condenser shell 1, the heating shell assembly 2, and the air outlet shell 4, arranged sequentially from top to bottom, form a vertical airflow circulation channel. Moist and hot air from the inner liner enters the condenser channel 101 through the first air inlet 102 of the condenser shell 1, is dehumidified by condensation, and is discharged from the first air outlet 103. Subsequently, the air is drawn into the heating channel 201 of the heating shell assembly 2 by the fan assembly 3 below, and the heated dry air then enters the bottom air outlet shell 4 and is sent back to the inner liner. This top-down layout allows the airflow to follow the natural gravity flow direction of "condensation and dehumidification → heating → drying," reducing resistance losses caused by horizontal turning.

[0068] like Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: 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, humid and hot air forms a through-flow within the channel. This ensures that the humid and hot air can completely pass through the condensation section 1012 and fully contact the condenser 12.

[0069] like Figure 10 and Figure 11 As shown, in addition to the features of the above embodiments, this embodiment further specifies 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 embodiments, this embodiment further includes a baffle assembly 5, which is rotatably mounted on the air outlet housing 4 and located at the third air inlet 402. 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 rotating the angle. When the drying process needs to be started, the baffle assembly 5 rotates to the open position, allowing the hot air from the heating channel 201 to smoothly enter the air outlet channel 401; when the machine is stopped, the baffle assembly 5 rotates to the closed position to prevent the humid and hot 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: the heating shell assembly 2 includes a first shell 21, a second shell 22, and a heating component 23. The first shell 21 is disposed on the second shell 22, and the first shell 21 and the second shell 22 cooperate to form a heating channel 201. The heating component 23 is disposed on the first shell 21. The structure of the first shell 21 disposed on the second shell 22 to form the heating channel 201 facilitates assembly and disassembly, simplifying equipment maintenance procedures. 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, improving operational convenience. By disposing of the heating component 23 on the first shell 21, the heating area can be precisely controlled according to the flow direction of the medium within the channel or the heating requirements.

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

[0073] In addition to the features of the above embodiments, this embodiment further specifies that the first housing 21 and the second housing 22 are connected by snap-fit ​​or screws.

[0074] like Figure 11 and Figure 12 As shown, in addition to the features of the above embodiments, this embodiment further includes a baffle assembly 5, which is rotatably mounted on the heating shell assembly 2 and located at the second air outlet 203. The baffle assembly 5 can open or close the second air outlet 203. The baffle assembly 5 is rotatably mounted at the second air outlet 203 of the heating shell assembly 2, and the air outlet can be opened or closed by rotation. When the drying process needs to be started, the baffle assembly 5 rotates to the open position, and the hot air in the heating channel 201 can flow smoothly into the air outlet shell 4; when the machine is stopped, the baffle assembly 5 rotates to the closed position, which can effectively prevent the hot and humid air in the air outlet shell 4 and the inner liner from flowing back into the heating channel 201, and avoid shortening the service life of the heating assembly 23 due to contact with moisture.

[0075] like Figure 11 and Figure 12 As shown, in addition to the features of the above embodiments, this embodiment further specifies 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 working, the rotating shaft portion 51 is in the first position, and the second air outlet 203 is open. When the fan assembly 3 stops working, 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 51 to the first position, keeping the second air outlet 203 open and ensuring that the hot air in the heating channel 201 is discharged smoothly. When the fan assembly 3 stops working, the gravity part 53 drives the rotating shaft 51 to rotate to the second position by its own gravity. At this time, the baffle 52 automatically blocks the second air outlet 203. The air outlet can be automatically opened and closed without the need for an additional driving device, which improves the intelligence and ease of use of the equipment.

[0076] Example 2

[0077] This embodiment discloses a dishwasher, including:

[0078] The aforementioned internal circulation drying device.

[0079] The dishwasher disclosed in this application is equipped with the aforementioned internal circulation drying device. Through the cooperation of components such as the condenser shell 1 and the heating shell assembly 2, it can quickly reduce the surface humidity of tableware.
