Description

Technical Field

[0001] This application relates to the technical field of air duct structures, and more particularly to a drying air duct structure. Background Technology

[0002] In the field of teacup cleaning devices, traditional drying duct designs have certain limitations. Currently common drying ducts typically have only one air outlet, primarily used for drying teacups, thus limiting their applicability. This single-outlet drying duct cannot meet the diverse drying needs of teacup cleaning devices under complex operating conditions; for example, it cannot effectively dry the cleaning components within the cleaning chamber simultaneously. In actual use, if the cleaning components of a teacup cleaning device are not dried sufficiently in a timely manner, it may lead to surface dampness and bacterial growth, affecting the cleaning effect and lifespan of the device, increasing maintenance costs and the risk of malfunction, and limiting the overall performance improvement of the teacup cleaning device. Utility Model Content

[0003] The purpose of this application is to provide a drying air duct structure to solve the technical problems of the prior art.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] On the one hand, a drying air duct structure is provided, which is applied to a cup washing and drying device having at least two cavities. The drying air duct structure includes: a shell and a baffle. An air supply channel is formed inside the shell. The shell is provided with two air outlets that are respectively connected to the air supply channel. The two air outlets are respectively connected to the two cavities one by one. The baffle is disposed inside the shell and can move relative to the shell so that hot air is output from either of the two air outlets or from both air outlets simultaneously.

[0006] Furthermore, it also includes a power component. The wind deflector is disposed inside the housing. The drive end of the power component is connected to the wind deflector for driving the wind deflector to switch between a first state and a second state. When the wind deflector is in the first state, either of the two air outlets is connected to the air supply channel. When the wind deflector is in the second state, both air outlets are connected to the air supply channel.

[0007] Furthermore, the two air outlets are respectively a first air outlet and a second air outlet. The first state includes the wind deflector rotating to a first position or a second position under the drive of the power component. When the wind deflector rotates to the first position, the first air outlet and the air supply channel are connected. When the wind deflector rotates to the second position, the second air outlet and the air supply channel are connected.

[0008] Furthermore, the inner wall of the housing is provided with windproof protrusions corresponding to the two air outlets one by one. The air outlets are located on the leeward side of the windproof protrusions. When the windproof component is in the first state, the windproof component is located on the leeward side of one of the windproof protrusions. The windproof protrusion is used to block the wind in the air supply channel from passing through the gap between the inner wall of the side where the windproof protrusion is located and the windproof component.

[0009] Furthermore, a detection component is also provided on the housing, which is used to detect the position of the windshield.

[0010] Furthermore, the detection component includes a photoelectric sensor disposed on the outside of the housing and a light-blocking component disposed on the outside of the housing and coaxially connected to the windshield component. The photoelectric sensor detects the position of the light-blocking component and thus obtains the position of the windshield component.

[0011] Furthermore, at least one of the air outlets is equipped with an air guide, which is used to guide hot air to blow out at an angle downwards.

[0012] Furthermore, the air guide is a one-piece molded part made of elastic material.

[0013] Furthermore, the housing is provided with a drain outlet at a height lower than the air outlet, the drain outlet being used to drain water that enters the housing.

[0014] Furthermore, one of the cavities is a cleaning cavity, and a water-blocking part is provided inside the housing, the water-blocking part being located on the side of the drain outlet away from the cleaning cavity.

[0015] The beneficial effects of this application are as follows: The drying duct structure described in this application is applied to a cup washing and drying device with at least two cavities. Its core lies in setting two air outlets that connect to the two cavities respectively, and using a movable baffle to flexibly control the flow direction of hot air. When a cavity needs to be dried, the baffle moves to the corresponding position, causing hot air to blow out only from the corresponding air outlet, concentrating on drying the teacups or cleaning components in the target cavity. When two cavities need to be dried simultaneously, the baffle is in a specific position, allowing hot air to be output from both air outlets simultaneously, achieving synchronous drying of the two cavities. This flexible duct control mechanism allows the drying duct to precisely guide hot air to the required cavity according to different needs, completing an efficient drying operation.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0026] like Figures 1 to 5 As shown, this embodiment provides a drying air duct structure, applied to a cup washing and drying device with at least two cavities. The drying air duct structure includes: a housing 1 and a baffle 2. An air supply channel 101 is formed inside the housing 1. The housing 1 is provided with two air outlets 102 that are respectively connected to the air supply channel 101. The two air outlets 102 are respectively connected to the two cavities one by one. The baffle 2 is disposed inside the housing 1 and can move relative to the housing 1 so that hot air is output from either of the two air outlets 102 or from both air outlets 102 simultaneously.

[0027] Based on the above scheme, the two chambers are specifically a cleaning chamber and a drying chamber. Hot air enters the air supply channel 101 of the housing 1 under the action of the fan 10, or cold air enters the air supply channel 101 under the action of the fan 10 and is heated. When only the teacup needs to be dried, the baffle 2 moves to the position of blocking the air outlet 102 connecting the cleaning chamber, and all the hot air is blown out from the air outlet 102 connected to the drying chamber, forming a strong hot airflow to quickly remove moisture from the surface of the teacup. When only the cleaning element needs to be dried, the baffle 2 moves to the position of blocking the air outlet 102 connecting the drying chamber, and the hot air is output from the air outlet 102 connected to the cleaning chamber, precisely targeting the cleaning element to dry it. More uniquely, if both chambers need to be dried at the same time, the baffle 2 can be placed in a specific intermediate position, so that hot air is output from both air outlets 102 at the same time, realizing synchronous operation. The whole process only requires controlling the position of the baffle 2, which is simple to operate, yet can meet complex and varied drying needs.

[0028] In this solution, from a drying efficiency perspective, the dual air outlets 102 target the drying chamber and the cleaning chamber respectively, simultaneously removing moisture from the surface of the teacup and residual moisture from the cleaning components. Compared to the traditional single air outlet 102, the drying effect per unit time is significantly improved. Regarding lifespan, the timely drying of the cleaning components prevents bacterial erosion and corrosion in a humid environment, thus extending the equipment's lifespan. From the user's perspective, this flexible drying mode greatly enhances the equipment's applicability and convenience. For example, in places like hotels, it can meet the need for quick cleaning and drying of teacups while also maintaining the equipment's own cleaning components; in home settings, users can flexibly choose the drying mode according to their actual needs, achieving rational resource utilization.

[0029] Furthermore, it also includes a power component 3. The wind deflector 2 is disposed inside the housing 1. The drive end of the power component 3 is connected to the wind deflector 2 for driving the wind deflector 2 to switch between a first state and a second state. When the wind deflector 2 is in the first state, either of the two air outlets 102 is connected to the air supply channel 101, and hot air is blown out only from that air outlet 102 to precisely dry the corresponding cavity. When the wind deflector 2 is in the second state, both air outlets 102 are connected to the air supply channel 101, and hot air is evenly distributed and output from the two air outlets 102 to achieve synchronous drying of the drying cavity and the cleaning cavity. Through the precise control of the power component 3, the drying mode can be flexibly selected according to actual needs. The operation is simple and highly automated, ensuring that the equipment can operate efficiently under different working conditions.

[0030] By introducing a power component 3 to automate the switching of the wind deflector 2, the intelligence level and ease of operation of the equipment are effectively improved. Users no longer need to manually adjust the wind deflector 2, reducing the risk of misoperation and improving the user experience. Secondly, this flexible drying mode switching mechanism can fully meet the diverse needs of different scenarios. When only teacups or cleaning components need to be dried, the corresponding air outlet 102 can be opened separately to concentrate hot air resources, improve drying efficiency, and save energy; while when both teacups and cleaning components need to be dried simultaneously, it can quickly switch to the synchronous drying mode, saving time and improving overall work efficiency. In addition, the stable drive of the power component 3 ensures the accuracy and reliability of the switching of the wind deflector 2, further enhancing the stability and durability of the equipment, reducing the failure rate and maintenance costs, and promoting the development of cup washing and drying devices towards intelligence and high efficiency.

[0031] As an optional specific implementation, the movement of the wind deflector 2 can also be adjusted manually. For example, a handle can be provided on the outside of the housing 1, and the handle can be extended into the inside of the housing 1 and connected to the wind deflector 2. The wind deflector 2 can be switched freely by manual control. Compared with the automated solution, this solution has an advantage in manufacturing cost.

[0032] In some embodiments, the two air outlets 102 are defined as a first air outlet 102 and a second air outlet 102, respectively communicating with the drying chamber and the cleaning chamber. The movement of the baffle 2 inside the housing 1 is driven by the power component 3, specifically manifested as the rotation of the baffle 2. When the power component 3 drives the baffle 2 to rotate to the first position, the passage between the baffle 2 and the first air outlet 102 and the air supply channel 101 is aligned, so that hot air is blown out only from the first air outlet 102 to dry the teacup in the drying chamber; while when the power component 3 drives the baffle 2 to rotate to the second position, the passage between the baffle 2 and the second air outlet 102 and the air supply channel 101 is aligned, and hot air is blown out from the second air outlet 102 to dry the cleaning element in the cleaning chamber. This design achieves individual drying control of different chambers by precisely controlling the rotation position of the baffle 2, ensuring that hot air can be accurately delivered to the area that needs to be dried.

[0033] As another optional specific implementation scheme, the movement mode of the wind deflector 2 can be sliding. The wind deflector 2 slides to the first position or the second position under the drive of the power component 3. By precisely controlling the sliding position of the wind deflector 2, individual drying control of different cavities can be achieved to meet diverse drying needs.

[0034] In addition, the inner wall of the housing 1 is provided with wind-blocking protrusions 4 corresponding to the two air outlets 102, with the air outlets 102 located on the leeward side of the wind-blocking protrusions 4. When the power unit 3 drives the wind-blocking component 2 to the first state, the wind-blocking component 2 is located on the leeward side of one of the wind-blocking protrusions 4. At this time, the wind-blocking protrusion 4 plays a crucial blocking role, effectively preventing air from leaking from the air in the air supply channel 101 through the gap between the inner wall of the wind-blocking protrusion 4 and the wind-blocking component 2. This design ensures the concentration of air pressure, so that the hot air in the air supply channel 101 can only be blown out from the corresponding air outlet 102, accurately targeting the target cavity that needs to be dried. Whether it is a teacup in the drying cavity or a cleaning element in the cleaning cavity, efficient and concentrated drying can be achieved. When it is necessary to switch to the second state, the power unit 3 drives the wind-blocking component 2 to move to another position. At this time, the wind-blocking protrusion 4 corresponding to the other air outlet 102 starts to work, blocking the air leakage on the other side, realizing the independent drying function of the other air outlet 102. By providing a baffle protrusion 4 corresponding to the air outlet 102 on the inner wall of the housing 1, and cleverly designing the air outlet 102 on the leeward side of the baffle protrusion 4, hot air leakage from the gap between the baffle 2 and the inner wall of the housing 1 is effectively prevented, thus improving drying efficiency and energy utilization. In practical applications, this design ensures that hot air can be accurately delivered to the area requiring drying, achieving a fast and uniform drying effect whether drying teacups or cleaning components.

[0035] It is worth mentioning that a detection component 5 is also provided on the housing 1, which is used to detect the position of the baffle 2. When the power component 3 drives the baffle 2 to move within the housing 1, the detection component 5 monitors the position status of the baffle 2 in real time. When the baffle 2 is in the first state (i.e., in the first position or the second position), the detection component 5 can accurately identify and confirm whether the baffle 2 has accurately reached the designated position. This real-time monitoring function ensures that the automated control system of the equipment can perform precise operation and switching according to the actual position of the baffle 2, thereby realizing individual drying control of different chambers. Through the feedback of the detection component 5, the equipment can adjust the drive of the power component 3 in a timely manner to ensure that the movement and positioning of the baffle 2 are accurate, ensuring the efficiency and stability of the drying process. Moreover, the feedback mechanism of the detection component 5 enables the equipment to adjust and optimize the drying process in a timely manner, enhancing the stability and durability of the equipment.

[0036] Specifically, the detection component 5 consists of a photoelectric sensor 501 and a light-blocking component 502. The photoelectric sensor 501 is mounted on the outside of the housing 1, and the light-blocking component 502 is also located on the outside of the housing 1, and is coaxially connected to the wind-blocking component 2. When the power component 3 drives the wind-blocking component 2 to change position within the housing 1, the light-blocking component 502 rotates synchronously. Due to the precise transmission relationship between the two, the positional change of the light-blocking component 502 can directly reflect the positional state of the wind-blocking component 2. The photoelectric sensor 501 monitors the movement of the light-blocking component 502 in real time. When the light-blocking component 502 enters the detection area of ​​the photoelectric sensor 501, the sensor can quickly capture this signal change. In this way, the equipment's control system can accurately obtain the positional information of the wind-blocking component 2, thereby achieving real-time monitoring of the position of the wind-blocking component 2, and precisely controlling the operation of the drying duct based on the monitoring results, ensuring the efficiency and stability of the drying process, and meeting the drying requirements of different chambers.

[0037] By introducing a detection component 5 consisting of a photoelectric sensor 501 and a light-blocking element 502, precise monitoring of the position of the wind-blocking element 2 is achieved, providing a crucial guarantee for the efficient operation of the equipment. The photoelectric sensor 501, with its non-contact detection, fast response speed, and high accuracy, can capture real-time positional changes of the light-blocking element 502, thereby indirectly obtaining the accurate position of the wind-blocking element 2. This design not only improves the intelligence level of the equipment but also enhances its stability and reliability, ensuring that hot air is accurately delivered to the area requiring drying, thus improving drying efficiency and energy utilization. Simultaneously, this real-time monitoring mechanism facilitates timely detection and correction of positional deviations in the wind-blocking element 2, reducing equipment failure rates, minimizing maintenance costs, and extending equipment lifespan.

[0038] Optionally, at least one air outlet 102 is equipped with an air guide 6, which guides the hot air to be blown downwards at an angle. When hot air enters the air outlet 102 from the air supply channel 101, the air guide 6, through its unique tilt angle and shape, adjusts the flow direction of the hot air to a downward angle. This design allows the hot air to cover the surface of the teacup or cleaning element in a more fluid dynamic manner, forming a uniform and concentrated hot air curtain. In this way, the hot air can not only blow onto all surfaces of the target object more efficiently, but also reduce the direct impact of the hot air at the air outlet 102, avoiding local overheating or damage caused by direct hot air blowing. The presence of the air guide 6 optimizes the distribution of hot air to a certain extent, ensuring the uniformity and efficiency of the drying effect and improving the overall performance of the equipment. Most importantly, the hot air is relatively light, so the downward-blown hot air can better diffuse upwards within the cavity, making the entire cavity evenly filled with heat and improving drying efficiency.

[0039] Meanwhile, the air guide 6 is a one-piece molded component made of elastic material. The elasticity of the air guide 6 is mainly reflected in its installation and disassembly process, allowing it to be easily installed at the air outlet 102. It also allows for elastic deformation under external force without damage. The one-piece molding design ensures the structural integrity of the air guide 6, improving its durability and reliability. During use, the air guide 6 continuously guides hot air out at the optimal angle, optimizing the drying effect and extending the service life of the equipment.

[0040] Generally, the housing 1 is provided with a drain outlet 7 at a height lower than the air outlet 102. The drain outlet 7 is used to drain water that enters the housing 1. When hot air flows in the air supply channel 101 and is blown out from the air outlet 102, a small amount of water vapor may enter the housing 1 with the hot air, or in some cases, water in the cavity may accidentally enter the housing 1. Because the drain outlet 7 is located lower than the air outlet 102, water naturally collects in the area where the drain outlet 7 is located under the action of gravity and is discharged outside the housing 1 through the drain outlet 7. This design effectively prevents water from accumulating inside the housing 1, avoiding equipment damage or reduced drying efficiency caused by water accumulation. At the same time, the position of the drain outlet 7 ensures that it can efficiently drain accumulated water without affecting the flow of hot air, maintaining the normal operation of the equipment and the drying effect.

[0041] Furthermore, the housing 1 is provided with a water-blocking part 8, which is located on the side of the drain outlet 7 opposite to the cleaning chamber. When water accidentally enters the housing 1 from the cleaning chamber, it flows towards the drain outlet 7 under gravity. The water-blocking part 8 plays a crucial blocking role, preventing water from overflowing the drain outlet 7 and entering other locations in the air supply channel 101, such as the locations where the heating device 9 and the fan 10 are installed, when the amount of water is excessive. By setting up the water-blocking part 8, the water is effectively blocked and guided to the drain outlet 7, ensuring that all water can be smoothly discharged from the drain outlet 7, avoiding damage to key components such as the heating device 9 and the fan 10, and ensuring the normal operation of the equipment and the drying effect.

[0042] In addition, a thermostat 11 is also provided on the housing 1. The thermostat 11 is used to detect the temperature inside the air supply channel 101. When the thermostat 11 detects that the temperature inside the air supply channel 101 exceeds the preset temperature threshold, it will immediately trigger the power-off protection, causing the heating device 9 to stop heating. Alternatively, the thermostat 11 is electrically connected to the heating device 9. When the temperature exceeds the preset temperature threshold, the thermostat 11 sends a corresponding control signal to the heating device 9 to control the heating device 9 to stop working independently. After the temperature drops to the normal range, the heating device 9 is then controlled to start heating again. This way, it will not have a significant impact on the operation of the entire device, and it can also ensure the safety and stability of operation.
