Technical Field

[0001] This application relates to the technical field of the drainage structure of a heat pump dryer, and particularly to a drainage structure of a heat pump dryer. Background Art

[0002] The heat pump dryer performs heat exchange through an evaporator and a condenser to evaporate the water in the clothes and condense the wet air, achieving the functions of drying clothes and removing water. In this process, the evaporator absorbs the heat in the wet air and condenses the water vapor into water. Therefore, a water receiving tray is usually designed below the evaporator to collect the condensed water. The water receiving tray should have a certain capacity to ensure continuous collection of condensed water during the drying process. Due to the long-term use of the dryer, excessive dirt will accumulate in the water receiving tray, blocking the water outlet in the water receiving tray and preventing the condensed water from draining. Utility Model Content

The water receiving component is arranged below the evaporator, and the cleaning component is arranged on the air inlet surface of the evaporator;

[0006] The water receiving component includes a water receiving tray, a filter screen, a rotating roller, and a drain pipe. A water receiving cavity is formed in the water receiving tray, and the projected area of the evaporator in the water receiving cavity along the vertical direction is less than or equal to the area of the water receiving cavity. The filter screen is detachably installed above the water receiving cavity. A drain port is formed on the side surface of the water receiving tray, and the drain port is communicated with the water receiving cavity. One end of the drain pipe is connected to the drain port. The rotating roller is arranged in the water receiving cavity, and bristles are arranged along its length direction.

[0007] Further, an embedding port is formed on the other side surface of the water receiving tray. The embedding port horizontally extends towards the drain port direction, and an embedding groove is formed on the inner wall of the water receiving cavity. The filter screen passes through the embedding port and slides and fits above the water receiving cavity along the embedding groove.

[0008] Further, the water receiving cavity includes opposite first inner wall surface and second inner wall surface. The bottom wall of the water receiving cavity slopes downward from the second inner wall surface towards the first inner wall surface direction, and the drain port penetrates through the first inner wall surface.

[0009] Further, the rotating roller is disposed at a position 5-10 cm away from the first inner wall surface.

[0010] Further, the rotating roller is configured to rotate clockwise from the second inner wall surface towards the first inner wall surface.

[0011] Further, the cleaning assembly includes a spraying member disposed above the air inlet surface of the evaporator and a splash guard disposed below the air inlet surface of the evaporator, and a water storage cavity is formed in the splash guard.

[0012] Further, water outlet ports communicating with the water receiving cavity are formed on both side surfaces of the splash guard along its length direction.

[0016] The beneficial effects of the present application are as follows: It aims to effectively solve the common drainage blockage problem in traditional dryers by efficiently collecting, filtering, and accelerating the discharge of condensed water. The structure includes an evaporator, a water receiving component, and an innovative cleaning component. During the drying process, the evaporator absorbs the heat in the humid air, causing the water vapor to condense into water, which then drips into the water receiving component below. The water receiving component includes a water receiving tray with a water receiving cavity formed inside for collecting condensed water. The projected area of the evaporator in the water receiving cavity along the vertical direction is designed to be less than or equal to the area of the water receiving cavity, ensuring that all condensed water can be effectively collected and preventing overflow.

Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of this application.

[0027] In this application, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above", and "on the top" of the second feature includes that the first feature is directly above and obliquely above the second feature, or only means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below", and "under the bottom" of the second feature includes that the first feature is directly below and obliquely below the second feature, or only means that the horizontal height of the first feature is lower than that of the second feature.

[0028] As Figures 1-6As shown in the figure, this embodiment provides a drainage structure for a heat pump dryer, including: an evaporator 1, a water receiving component 2, and a cleaning component 3. The water receiving component 2 is arranged below the evaporator 1, and the cleaning component 3 is arranged on the air inlet surface of the evaporator 1. The water receiving component 2 includes a water receiving tray 201, a filter screen 202, a rotating roller 203, and a drain pipe 204. A water receiving cavity 2011 is formed in the water receiving tray 201, and the projected area of the evaporator 1 in the water receiving cavity 2011 in the vertical direction is less than or equal to the area of the water receiving cavity 2011. The filter screen 202 is detachably installed above the water receiving cavity 2011. A drain port 2012 is formed on the side surface of the water receiving tray 201, and the drain port 2012 is communicated with the water receiving cavity 2011. One end of the drain pipe 204 is connected to the drain port 2012. The rotating roller 203 is arranged in the water receiving cavity 2011, and bristles are arranged along its length direction.

[0029] Based on the above solution, it aims to effectively solve the common drainage blockage problem in traditional dryers by efficiently collecting, filtering, and accelerating the discharge of condensed water. This structure includes an evaporator 1, a water receiving component 2, and an innovative cleaning component 3. During the drying process, the evaporator 1 absorbs the heat in the humid air, causing the water vapor to condense into water, which then drips into the water receiving component 2 below. The water receiving component 2 includes a water receiving tray 201 with a water receiving cavity 2011 formed inside for collecting condensed water. The projected area of the evaporator 1 in the water receiving cavity 2011 in the vertical direction is designed to be less than or equal to the area of the water receiving cavity 2011 to ensure that all condensed water can be effectively collected and prevent overflow. Above the water receiving cavity 2011, a detachable filter screen 202 is installed, which can intercept and accumulate impurities, dust, and other dirt in the condensed water, effectively preventing these dirt from entering the drainage system, thereby keeping the drain port 2012 unobstructed. To further accelerate the discharge of condensed water, a rotating roller 203 is also arranged in the water receiving tray 201. The rotating roller 203 is equipped with bristles along its length direction. When the rotating roller 203 is started, the bristles will rotate and actively sweep the accumulated water from the bottom of the water receiving cavity 2011 towards the drain port 2012. This design not only significantly speeds up the discharge rate of condensed water but also physically cleans the dirt at the bottom of the water receiving cavity 2011, further reducing the risk of blockage. Finally, the condensed water after filtration and acceleration is smoothly discharged outside the dryer through the drain pipe 204, and the drain pipe 204 is tightly connected to the drain port 2012 of the water receiving tray 201 to ensure seamless connection and efficient completion of the drainage process. In summary, the drainage structure of this application integrates innovative elements such as the filter screen 202 and the rotating roller 203, which not only effectively prevents drainage blockage, improves drainage efficiency, but also facilitates users' daily maintenance, significantly enhancing the overall performance and user experience of the heat pump dryer.

[0030] To enhance the user experience and facilitate cleaning and maintenance, the design of the water receiving tray 201 in this application also includes a fitting opening 2015 and a fitting groove 2016 structure. Specifically, a fitting opening 2015 is provided on the other side of the water receiving tray 201, and this fitting opening 2015 extends horizontally towards the drain opening 2012, providing a convenient channel for users to install and remove the filter net 202. On the inner wall of the water receiving cavity 2011, a fitting groove 2016 is formed at a position corresponding to the fitting opening 2015, and this fitting groove 2016 extends along the direction of the fitting opening 2015, providing a stable installation track for the filter net 202. When the user needs to install the filter net 202 above the water receiving cavity 2011, just align the filter net 202 with the fitting opening 2015, and then gently slide it along the fitting groove 2016, and the filter net 202 can be easily fitted in place and firmly fixed. This sliding and fitting design not only simplifies the installation and removal process of the filter net 202, enabling users to easily complete the operation without the need for any tools, but also improves the stability and sealing performance of the filter net 202, effectively preventing the condensed water from bypassing the filter net 202 and directly flowing into the drain opening 2012, thereby further enhancing the filtering effect of the drainage structure.

[0031] Furthermore, to optimize the collection and drainage efficiency of the condensed water, the water receiving cavity 2011 is designed to have opposite first inner wall surface 2013 and second inner wall surface 2014, and these two inner wall surfaces jointly enclose the collection space for the condensed water. The key design improvement lies in the bottom wall of the water receiving cavity 2011, which is not completely horizontal, but gradually slopes downward from the second inner wall surface 2014 towards the first inner wall surface 2013. This inclined design enables the condensed water dripping into the water receiving cavity 2011 to naturally flow towards the vicinity of the first inner wall surface 2013, thus more effectively converging to the drain opening 2012 area. The drain opening 2012 is provided on the first inner wall surface 2013 and penetrates through the side wall of the entire water receiving tray 201 and is connected to the external drain pipe 204. Due to the inclined design of the bottom wall, the condensed water can smoothly flow towards the drain opening 2012 under the action of gravity and be quickly discharged through the drain pipe 204, avoiding the occurrence of water accumulation.

[0032] Furthermore, the rotating roller 203 is 5 - 10 cm away from the first inner wall surface 2013. The selection of this position is based on multiple considerations. First, it ensures that the bristles on the rotating roller 203 can fully cover most areas of the water receiving cavity 2011 during rotation, thus effectively sweeping the accumulated water towards the drain outlet 2012 and accelerating the drainage process. Second, this position maintains a certain distance from the drain outlet 2012, avoiding direct contact or collision between the rotating roller 203 and the drain outlet 2012 during operation, and reducing the possibility of failures. Finally, the 5 - 10 cm spacing also takes into account the convenience of cleaning and maintenance, enabling users to operate more smoothly when cleaning the water receiving cavity 2011 and replacing the filter screen 202.

[0033] Meanwhile, the rotating roller 203 is configured to rotate clockwise from the second inner wall surface 2014 towards the first inner wall surface 2013. When the rotating roller 203 rotates clockwise, the bristles on it will sweep along the inclined bottom wall from the second inner wall surface 2014 towards the first inner wall surface 2013, and this sweeping direction is consistent with the natural flow direction of the condensate towards the drain outlet 2012, thereby being able to more effectively push the accumulated water towards the drain outlet 2012 area. In addition, the clockwise rotation helps to prevent the reverse flow phenomenon of the rotating roller 203 during operation, further improving the drainage efficiency.

[0034] In some embodiments, the cleaning component 3 includes a spraying member 301 disposed above the air inlet surface of the evaporator 1 and a splash guard 302 disposed below the air inlet surface of the evaporator 1. A water storage cavity 3021 is formed in the splash guard 302, and water outlet openings communicating with the water receiving cavity 2011 are formed on both side surfaces of the splash guard 302 along its length direction. The spraying member 301 is disposed above the air inlet surface of the evaporator 1, and its function is to spray cleaning liquid or clean water onto the surface of the evaporator 1 to remove impurities such as dust and dirt attached to the evaporator 1. This spraying cleaning method can not only effectively improve the cleanliness of the evaporator 1, but also maintain its good heat exchange efficiency, thereby extending the service life of the heat pump dryer. In order to prevent the liquid generated during the spraying process from splashing onto other components of the dryer, a splash guard 302 is also provided below the air inlet surface of the evaporator 1. A water storage cavity 3021 is formed inside the splash guard 302 for collecting the liquid dripping from the spraying member 301. At the same time, water outlet openings communicating with the water receiving cavity 2011 are formed on both side surfaces of the splash guard 302 along its length direction. In this way, the liquid collected in the water storage cavity 3021 can be smoothly discharged into the water receiving cavity 2011 through the water outlet openings and finally discharged outside the dryer through the drain pipe 204. This design not only avoids the problem of liquid splashing during the spraying cleaning process, but also realizes the recycling and effective discharge of the cleaning liquid. In addition, the presence of the splash guard 302 can also block dust and impurities below the air inlet surface of the evaporator 1 from entering the water receiving cavity 2011 to a certain extent, further ensuring the cleanliness and smoothness of the drainage system.

[0035] Specifically, the spraying member 301 includes a support portion 3011 protruding from the air inlet surface of the evaporator 1 and a spray head 3012 installed below the support portion 3011. The spray head 3012 can slide along the length direction of the support portion 3011, and the spraying direction of the spray head 3012 is opposite to the air inlet surface of the evaporator 1. The design of the support portion 3011 ensures that the spraying member 301 can be firmly fixed above the air inlet surface of the evaporator 1. At the same time, its protruding shape also provides sufficient installation space and adjustment room for the spray head 3012. The spray head 3012 is installed below the support portion 3011 through a slide rail or a card slot, etc., so that it can slide along the length direction of the support portion 3011. The spraying direction of the spray head 3012 is specifically designed to be opposite to the air inlet surface of the evaporator 1, which means that when the spray head 3012 works, it can directly spray cleaning liquid or clean water onto the surface of the evaporator 1, thereby achieving full coverage and effective cleaning of the air inlet surface of the evaporator 1. In addition, the function of the spray head 3012 sliding along the support portion 3011 further enhances the flexibility and adaptability of its cleaning, and the spraying range and intensity can be adjusted according to actual needs to achieve the best cleaning effect.

[0036] Optionally, the evaporator 1 includes four support columns 101 and heat exchange fins 102. The four support columns 101 are arranged in an array to form an installation cavity for installing the heat exchange fins 102. A clamping groove 1011 is formed on the outer wall surface of each support column 101, and an elastic buckle 205 that cooperates with the clamping groove 1011 is provided on the water receiving tray 201. The four support columns 101 are arranged in an array, maintaining a certain distance and angle from each other, and together constitute a stable installation framework. Inside this installation framework, an installation cavity for installing the heat exchange fins 102 is formed. The heat exchange fins 102 are fixed in the installation cavity according to a specific arrangement to achieve an efficient heat exchange function. To stably install the water receiving tray 201 below the evaporator 1, clamping grooves 1011 are specifically formed on the outer wall surface of the support columns 101. The shape, size, and position of these clamping grooves 1011 are designed to ensure perfect cooperation with the elastic buckles 205 provided on the water receiving tray 201. During the installation process, the user only needs to align the water receiving tray 201 with the position below the support columns 101 and then gently press down, so that the elastic buckles 205 automatically snap into the clamping grooves 1011 to complete the installation. This clamping connection method not only simplifies the installation steps and improves the installation efficiency but also ensures a stable connection between the water receiving tray 201 and the evaporator 1. At the same time, due to the adoption of the elastic buckle 205 design, the water receiving tray 201 has a certain degree of tolerance during the installation process, and even if the position is slightly deviated, the installation can be successfully completed, further enhancing the user experience.

[0037] Preferably, the water receiving assembly 2 further includes a power member, and the power end of the power member is connected to the rotating roller 203. The power member, such as a motor, an air pump, or other forms of driving devices, is integrated into the water receiving assembly 2, and its power end is directly connected to the rotating roller 203. When it is necessary to accelerate the discharge of condensed water, the power member is activated to generate a driving force, and this driving force is transmitted to the rotating roller 203 through the power end. The rotating roller 203 starts to rotate under the action of the driving force, and the bristles on it also rotate accordingly, effectively pushing the accumulated water in the water receiving cavity 2011 towards the drain port 2012. This mechanized drainage method not only significantly improves the drainage efficiency but also reduces the operation burden of the user.

[0038] In addition, the introduction of the power member also makes the working state of the water receiving assembly 2 more controllable and stable. The user can set the working mode and parameters of the power member, such as rotation speed, working time, etc., through a control panel or an intelligent control system to adapt to different usage scenarios and requirements. The improvement of this flexibility and intelligence will undoubtedly further enhance the overall performance and user experience of the heat pump clothes dryer.
