Description

Technical Field

[0001] This invention relates to the field of household appliance technology, specifically to a waterproof air outlet device and a drying equipment. Background Technology

[0002] A drying machine is a device that quickly dries clothes and other items. Its working principle involves increasing air temperature, airflow speed, and expanding the evaporation area to achieve rapid drying. Common heating methods used in drying machines include electric heating wire and semiconductor heating.

[0003] When existing drying equipment is in use, water droplets fall onto the shell and splash, and the splashed water can easily enter the equipment through the air outlet, causing equipment damage and safety issues. Summary of the Invention

[0004] In view of this, the present invention provides a waterproof air outlet device and a drying equipment to solve the problem that water easily enters the interior of existing drying equipment, causing equipment damage and affecting safety during use.

[0005] In a first aspect, the present invention provides a waterproof air outlet device, comprising,

[0006] case;

[0007] An air outlet hood is disposed on the top of the housing. The air outlet hood is provided with multiple air outlet grilles, and a water-blocking structure is provided at the bottom of the gap between adjacent air outlet grilles.

[0008] A water baffle is disposed on top of the air outlet hood, and the horizontal dimension of the water baffle is larger than the horizontal dimension of the air outlet hood.

[0009] Beneficial effects: By installing a water-blocking structure at the bottom of the air outlet grille gap, when water droplets fall to the top of the housing, the water-blocking structure can block the splashing water droplets, preventing water from splashing into the air outlet hood through the air outlet grille gap, thus preventing equipment damage and improving the safety of equipment use. At the same time, a water-blocking cover is installed on the top of the air outlet hood, and the horizontal dimension of the water-blocking cover is larger than that of the air outlet hood, so that the water-blocking cover can block the air outlet hood, preventing water dripping from above from entering the air outlet hood, further improving the safety of equipment use.

[0010] In one optional embodiment, the bottom edge of the water shield is provided with a splash-proof platform, and the top of the water shield is provided with a dividing rib corresponding to the position of the splash-proof platform.

[0011] Beneficial effects: By setting the dividing ribs, water droplets dripping on the top of the water shield are divided by the dividing ribs to form a water surface, preventing water droplets from accumulating at the edge of the water shield and preventing continuous collision and splashing of dripping water droplets with the edge of the water shield. At the same time, the splash-proof platform set on the back of the dividing ribs, due to its large width, prevents water at the edge of the water shield from flowing along the back, but instead drips downwards due to gravity, preventing water from flowing into the device and further improving the waterproof effect.

[0012] In one optional embodiment, the upper surface of the water shield is provided with an arc-shaped protrusion, the splash-proof platform and the arc-shaped protrusion are smoothly transitioned by a concave curved surface, and a converging structure is provided between the dividing rib and the arc-shaped protrusion; the waterproof air outlet device also includes a drainage structure, the drainage structure is connected to the converging structure, and the converging structure discharges water to the outside through the drainage structure.

[0013] Beneficial effects: By setting up a confluence structure, when water droplets fall onto the water-blocking cover, the water can be collected through the confluence structure, which facilitates the centralized discharge of accumulated water and prevents water from flowing into the device, thus improving the waterproof effect; by setting up a drainage structure connected to the confluence structure, it is easy to discharge the collected water, ensuring smooth drainage and improving drainage efficiency and effect.

[0014] In one optional embodiment, the water-blocking structure includes a plurality of water-blocking ribs, the height of which is H1. The value range of the height H1 is H1≥H2×C+5, where H2 is the height from the edge of the water-blocking cover to the top of the shell, and C is a constant and related to the material of the shell.

[0015] Beneficial effects: By setting the height H1 of the water-retaining ribs to H1≥H2×C+5, the waterproof effect is guaranteed while the air outlet grille is not excessively blocked, thereby increasing the air volume of the equipment and thus improving the drying effect.

[0016] In one alternative embodiment, a plurality of the air outlet grilles are arranged at circumferential intervals along the air outlet hood, and the air outlet grilles are arranged perpendicular to the water-blocking ribs.

[0017] Beneficial effects: By setting multiple air outlet grilles at circumferential intervals on the air outlet hood, the air outlet area is increased, the air outlet volume of the air outlet hood is improved, and the air outlet is made smoother. In addition, the air outlet grilles are set perpendicular to the water baffle ribs, so that the air outlet grilles do not overlap with each other, reducing the impact of the air outlet grilles on the air outlet area, not obstructing the air outlet, increasing the air outlet area, and thus increasing the air outlet volume of the air outlet hood.

[0018] In one optional embodiment, the water-blocking shield has a blocking length L over the air outlet shield, and the blocking length L satisfies the following relationship:

[0019] L=H2×C×sinα×2

[0020] In the above formula, α is the splash angle, 0°≤α≤90°;

[0021] The air outlet area of ​​the air outlet hood is S, and the air outlet area S satisfies the following relationship:

[0022] S = (H2 - H1) × d

[0023] In the above formula, d is the distance between adjacent air outlet grilles.

[0024] Beneficial effects: The formula for the shielding length L shows that the shielding length L is related to the height H2 from the edge of the water baffle to the top of the shell and the splash angle α. By calculating the shielding length L, the width of the water baffle can be determined. By controlling the ratio of the width of the water baffle to the shell size, the overall coordination and aesthetics of the equipment can be improved. The formula for the air outlet area S shows that the air outlet area S is related to the height H1 of the water baffle ribs, the spacing d between adjacent air outlet grilles, and the height H2 from the edge of the water baffle to the top of the shell. By calculating the air outlet area S, the maximum air volume can be achieved while satisfying the overall coordination and aesthetics of the equipment.

[0025] In one optional embodiment, the air outlet hood has an air outlet cavity communicating with the air outlet grille, and the top of the air outlet hood is provided with a protrusion protruding toward the air outlet cavity, the protrusion being configured as a raised arc-shaped surface structure.

[0026] Beneficial effects: By setting a protrusion that faces the air outlet, the air direction can be changed to a certain extent, causing the air to diffuse at an angle along the protrusion, thereby guiding the hot air to disperse around the protrusion, improving the airflow and diffusion effect, and shortening the airflow distance, thus improving the air outlet efficiency.

[0027] In one alternative embodiment, the inner surface of the protrusion is provided with a plurality of guide ribs.

[0028] Beneficial effects: By setting multiple guide ribs on the inner surface of the protrusion, the wind diffusion is made finer and more diffuse, reducing the high-frequency noise generated by concentrated wind noise and achieving the effect of wind guidance and noise reduction.

[0029] In one optional embodiment, a first foolproof positioning structure is provided between the air outlet cover and the water baffle cover, the first foolproof positioning structure being used to restrict the assembly direction during the assembly process of the air outlet cover and the water baffle cover.

[0030] Beneficial effects: The first foolproof positioning structure can guide and position the installation of the air outlet cover and the water baffle, making it easier for users to identify the relative directions of the air outlet cover and the water baffle when installing them. This allows the water baffle to be installed more accurately on top of the air outlet cover, improving installation efficiency and accuracy.

[0031] In one optional embodiment, the first anti-mistake positioning structure includes at least one anti-mistake rib and a first anti-mistake groove. The anti-mistake rib is disposed on one of the air outlet cover and the water baffle cover, and the first anti-mistake groove is disposed on the other of the air outlet cover and the water baffle cover.

[0032] Beneficial effects: By setting matching anti-foolproof ribs and the first anti-foolproof groove, the air outlet cover and the water baffle can be detachably connected, so that the water baffle can be detachably installed on the air outlet cover, which facilitates the installation and removal of the air outlet cover and the water baffle.

[0033] In one optional embodiment, a first guide structure is provided between the air outlet hood and the water baffle. The first guide structure includes a plurality of guide posts and guide grooves. The guide posts are disposed on one of the air outlet hood and the water baffle, and the guide grooves are correspondingly disposed on the other of the air outlet hood and the water baffle.

[0034] Beneficial effects: By setting a first guide structure between the air outlet cover and the water baffle, the installation of the air outlet cover and the water baffle can be guided and positioned, so that the water baffle can be quickly and accurately installed on the top of the air outlet cover, improving installation efficiency and accuracy.

[0035] In one optional embodiment, a second guide structure is provided between the air outlet cover and the water baffle cover. The second guide structure includes a plurality of assembly ribs, which are disposed on the air outlet cover and are correspondingly disposed with the air outlet grille.

[0036] Beneficial effects: By setting mounting ribs corresponding to the air outlet grille, the installation of the air outlet cover and the water baffle can be guided and positioned, so that the water baffle can be installed quickly and accurately, further improving installation efficiency and accuracy.

[0037] In one optional embodiment, a second foolproof positioning structure is provided between the air outlet cover and the housing, the second foolproof positioning structure being used to restrict the assembly direction during the assembly process of the air outlet cover and the housing.

[0038] Beneficial effects: By setting a second foolproof positioning structure, the installation of the air outlet cover and the housing can be guided and positioned, making it easier for users to identify the relative direction of the air outlet cover and the housing, so that the air outlet cover can be installed more accurately on the top of the housing, improving installation efficiency and accuracy.

[0039] In one optional embodiment, the second foolproof positioning structure includes at least one foolproof post and a second foolproof groove, wherein the foolproof post is disposed on one of the air outlet hood and the housing, and the second foolproof groove is correspondingly disposed on the other of the air outlet hood and the housing.

[0040] Beneficial effects: By setting matching anti-foolproof pillars and second anti-foolproof grooves, the air outlet cover and the housing can be detachably connected, thereby allowing the water baffle to be detachably installed on the housing, which facilitates the installation and removal of the air outlet cover and the housing.

[0041] In a second aspect, the present invention also provides a drying device, including a waterproof air outlet device as described in the first aspect above.

[0042] Beneficial effects: Since the drying equipment includes a waterproof air outlet device, it has the same effect as the waterproof air outlet device, so it will not be elaborated here.

[0043] In one alternative implementation, the drying equipment includes a clothes dryer or a clothes dryer.

[0044] Beneficial effects: This waterproof air outlet device is suitable for a variety of drying equipment and has strong applicability. Attached Figure Description

[0066] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0067] When using drying equipment with related technologies, water droplets fall onto the shell and splash, and the splashed water can easily enter the equipment through the air outlet, causing equipment damage and safety issues.

[0068] In view of the above problems, the present invention provides a waterproof air outlet device and drying equipment to prevent water from splashing into the air outlet cover 2 through the gap of the air outlet grille 201, thereby preventing equipment damage and improving the safety of equipment use.

[0069] The following is combined with Figures 1 to 10 The following describes embodiments of the present invention.

[0070] According to an embodiment of the present invention, a waterproof air outlet device is provided, including a housing 1, an air outlet cover 2, and a water-blocking cover 3. The housing 1 includes a detachable upper shell 101 and a lower shell 102. The air outlet cover 2 is disposed on the top of the upper shell 101. A plurality of air outlet grilles 201 are provided on the air outlet cover 2. A water-blocking structure is provided at the bottom of the gap between adjacent air outlet grilles 201. The water-blocking cover 3 is disposed on the top of the air outlet cover 2. The horizontal dimension of the water-blocking cover 3 is larger than the horizontal dimension of the air outlet cover 2, so that the water-blocking cover 3 can shield the air outlet cover 2, and water dripping from above will not enter the air outlet cover 2.

[0071] The waterproof air outlet device in this embodiment has a water-blocking structure installed at the lower part of the gap in the air outlet grille 201. When water droplets fall to the top of the housing 1, the water-blocking structure can block the splashing water droplets, preventing water from splashing into the air outlet hood 2 through the gap in the air outlet grille 201, thus preventing equipment damage and improving the safety of equipment use. At the same time, a water-blocking cover 3 is installed on the top of the air outlet hood 2, and the horizontal dimension of the water-blocking cover 3 is larger than the horizontal dimension of the air outlet hood 2, so that the water-blocking cover 3 can shield the air outlet hood 2, and the water dripping from above will not enter the air outlet hood 2, further improving the safety of equipment use.

[0072] like Figure 7 and 8 As shown, in one embodiment, a splash-proof platform 301 is provided at the bottom edge of the water shield 3, and a dividing rib 302 is provided at the top of the water shield 3 corresponding to the position of the splash-proof platform 301. By providing the dividing rib 302, water droplets dripping on the top of the water shield 3 will be divided by the dividing rib 302 to form a water surface, preventing water droplets from accumulating at the edge of the water shield 3 and preventing continuous collision and splashing of dripping water droplets with the edge of the water shield 3. At the same time, the splash-proof platform 301 provided on the back of the dividing rib 302 has a large width, so that water at the edge of the water shield 3 will not flow along the back, but will drip downwards due to gravity, preventing water from flowing into the device and further improving the waterproof effect.

[0073] like Figure 7As shown, in one embodiment, the upper end face of the water shield 3 is provided with an arc-shaped protrusion 203, the splash-proof platform 301 and the arc-shaped protrusion 203 are smoothly transitioned by a concave curved surface, and a confluence structure is provided between the dividing rib 302 and the arc-shaped protrusion 203.

[0074] In this embodiment, the confluence structure includes a confluence channel 303, which is arranged circumferentially along a concave curved surface. When water droplets fall onto the water shield 3, the water can be collected through the confluence channel 303, which facilitates the centralized discharge of accumulated water, prevents water from flowing into the device, improves the waterproof effect, and ensures that the water in the confluence structure can be discharged sequentially by setting a smoothly transitioning concave curved surface, thus preventing water accumulation.

[0075] like Figure 3 , 5 As shown in Figure 6, in one embodiment, a drainage structure is also included, which is connected to the confluence structure, and the confluence structure discharges water to the outside through the drainage structure.

[0076] In this embodiment, the drainage structure includes a drain hole 304 and a guide channel 204. There is one drain hole 304, located at the bottom of one corner of the confluence channel 303. The guide channel 204 is correspondingly located at one corner of the air outlet hood 2 and connects to two adjacent air outlet grilles 201. The length of the guide channel 204 is the same as the length of the air outlet grilles 201, allowing water discharged through the drain hole 304 to flow through the guide channel 204 to the bottom of the air outlet hood 2, and then along the air outlet hood 2 through the upper shell 101 to be discharged, preventing water from accumulating inside the device. By providing the drain hole 304 and the guide channel 204 connected to the confluence channel 303, the collected water can be discharged quickly and orderly, improving drainage efficiency and effect.

[0077] The shielding length of the water shield 3 to the air outlet shield 2 is L, and the shielding length L is the shielding length of one side of the water shield 3.

[0078] The blocking length L satisfies the following relationship 1: L = H² × C × sinα × 2

[0079] In the above formula, H2 is the height from the edge of the water shield 3 to the top of the upper shell 101, C is a constant and is related to the material of the upper shell 101, α is the splash angle, which is the angle between the splashed water droplet after the water droplet falls onto the upper shell 101 and the top surface of the upper shell 101, 0°≤α≤90°;

[0080] The air outlet area of ​​the air outlet hood 2 is S, and the air outlet area S satisfies the following relationship 2: S=(H2-H1)×d, where H1 is the height of the water-blocking rib 202 and d is the distance between adjacent air outlet grilles 201.

[0081] Specifically, the cross-sectional area of ​​the water shield 3 and the air outlet shield 2 is square. The length and width of the water shield 3 are both L1, and the length and width of the water shield rib 202 are both L2. The blocking length L of one side of the water shield 3 satisfies the following relationship 2: L=(L1-L2) / 2.

[0082] When water droplets fall on the top surface of the upper shell 101, the closer the droplets are to the air outlet grille 201 (the shorter the shielding length L), the more likely the splashed water droplets are to break through the height H1 of the water-blocking rib 202, causing the water droplets to enter the device. Therefore, the larger the shielding length L on one side of the water-blocking cover 3 and the height H1 of the water-blocking rib 202, the less likely water is to enter the device. However, if the shielding length L on one side of the water-blocking cover 3 is too large, the overall shape of the device will be inconsistent. If the height H1 of the water-blocking rib 202 is too large, it will block the air outlet grille 201 too much, resulting in a smaller air outlet area. For the above reasons, it is necessary to ensure the waterproof effect while maximizing the air outlet area.

[0083] When water droplets fall to the top of the upper shell 101, they disperse into multiple droplets. The maximum splash height of the water droplets is Y, which satisfies the following relationship 3: Y = H2 × C. When the water droplets reach the maximum splash height, the lateral distance of the splash is X, which satisfies the following relationship 4: X = Y × sinα. Based on the experiment, it was found that when X = L / 2, the height H1 of the water-blocking rib 202 meets the requirement of the maximum air outlet area, thus L = H2 × C × sinα × 2.

[0084] The following experimental calculations demonstrate the effects of the shielding length L, the height H2 from the edge of the water shield 3 to the top of the upper shell 101, the maximum splash height Y of the water droplets, and the air outlet area S.

[0085] It is known that water can be prevented from entering the air outlet hood 2 and causing danger when H1=Y+5. The splash angle α=45°, L2=125, the overall width of the device, that is, the width of the upper shell 101, is 235, and the spacing of the air outlet grilles 201 is d=5-6. In this embodiment, d=5.

[0086] Experimental data (1):

[0087] When H2=30, C=1 / 3, Y=10, X=5√2 is calculated. When L=(L1-L2)=2X, L1=125+10√2 is calculated. At this time, the ratio of the width of the whole machine to L1 is large, which makes the shape of the whole machine uncoordinated and unsightly. The air outlet area S=(H2-H1)×d=15d, so the air outlet area S=45 can be calculated.

[0088] Experimental data (2):

[0089] When H2=75, C=1 / 3, Y=25, X=12.5√2 is calculated. When L=(L1-L2)=2X, L1=125+25√2 is calculated. At this time, the ratio of the overall width of the device to L1 is moderate and the value is appropriate. The air outlet area S=(H2-H1)×d=45d, so the air outlet area S=225 can be calculated.

[0090] Experimental data (3):

[0091] When H2=120, C=1 / 3, Y=40, X=20√2 is calculated. When L=(L1-L2)=2X, L1=125+40√2 is calculated. At this time, the ratio of the overall width of the device to L1 is small, which is not aesthetically pleasing. The air outlet area S=(H2-H1)×d=75d, so the air outlet area S=375 can be calculated. At this time, H2 is the same as the height of 201 without the air outlet grille, and the overall height of the unit is not coordinated.

[0092] Based on the above three sets of experimental data, it can be found that when X=L / 2, that is, L=H2×C×sinα×2, the ratio of the overall width of the device to the water baffle 3 is moderate and relatively coordinated; when S=(H2-H1)×d, the air outlet area of ​​the air outlet hood 2 is the largest, that is, the height of the water baffle rib 202 is the lowest, and the obstruction of the air outlet grille 201 is minimal.

[0093] The formula for the shielding length L shows that the shielding length L is related to the height H2 from the edge of the water baffle 3 to the top of the housing 1 and the splash angle α. By calculating the shielding length L, the width of the water baffle 3 can be determined. By controlling the ratio of the width of the water baffle 3 to the size of the housing 1, the overall coordination and aesthetics of the equipment can be improved. The formula for the air outlet area S shows that the air outlet area S is related to the height H1 of the water baffle ribs, the distance d between adjacent air outlet grilles 201, and the height H2 from the edge of the water baffle 3 to the top of the housing 1. By calculating the air outlet area S, the maximum air volume can be achieved while satisfying the overall coordination and aesthetics of the equipment.

[0094] In one embodiment, the water-blocking structure includes a plurality of water-blocking ribs 202, the height of the water-blocking ribs 202 is H1, and the value range of the height H1 of the water-blocking ribs 202 is H1≥H2×C+5.

[0095] Based on the above formula H1=Y+5, we can deduce that H1=H2×C+5. In this embodiment, the height H1 of the water-blocking rib 202 is set to H1≥H2×C+5. This ensures the waterproof effect without excessively obstructing the air outlet of the air outlet grille 201, thereby increasing the air volume of the equipment and improving the drying effect.

[0096] like Figure 2As shown, in one embodiment, a plurality of air outlet grilles 201 are arranged at intervals along the circumference of the air outlet hood 2. The plurality of air outlet grilles 201 arranged at intervals along the circumference can increase the air outlet area, increase the air outlet volume of the air outlet hood 2, and can evenly outlet the air around the air outlet hood 2, making the air outlet smoother and improving the uniformity of the air outlet.

[0097] like Figure 2 As shown, in one embodiment, the air outlet grille 201 is arranged perpendicular to the water-blocking rib 202, which will not cause the air outlet grilles 201 to overlap with each other, reduce the impact of the air outlet grille 201 on the air outlet area, increase the air outlet area, and thus increase the air volume of the air outlet hood 2.

[0098] In other embodiments, the included angle between the air outlet grille 201 and the water-blocking rib 202 can be 70°, 80° or 85°, so that the adjacent air outlet grilles 201 have a certain overlapping and shielding effect when viewed from the front. In this case, the height of the water-blocking rib 202 can be appropriately reduced, which can also achieve the effect of waterproofing and air outlet.

[0099] like Figure 9 As shown, in one embodiment, the air outlet hood 2 has an air outlet cavity 205 communicating with the air outlet grille 201, and the top of the air outlet hood 2 is provided with a protrusion 206 protruding toward the air outlet cavity 205, and the protrusion 206 is configured as a raised arc-shaped surface structure.

[0100] In this embodiment, the air intake method is bottom intake (please refer to the airflow direction). Figure 9 (Indicated by the middle arrow) When air blows upwards into the air outlet hood 2, it impacts the protrusion 206. Since at least a portion of the protrusion 206 protrudes towards the air outlet cavity 205, this protruding shape causes the airflow to bounce back prematurely after impact, with most of the airflow being blown out through the air outlet grille 201. If the upper surface of the air outlet hood 2 is designed as a planar structure, the airflow will be blocked and bounced after hitting the planar structure, which to some extent reduces the speed of the airflow exiting from the air outlet grille 201 and reduces the airflow effect. However, in this embodiment, by providing the protrusion 206 protruding towards the air outlet cavity 205, the airflow direction can be changed to some extent, causing the airflow to diffuse at an angle along the protrusion 206, thereby guiding the hot air to disperse around the protrusion 206, improving the guiding and diffusion effect, and shortening the airflow distance, thus improving the airflow efficiency.

[0101] In one embodiment, the inner surface of the protrusion 206 is provided with a plurality of guide ribs.

[0102] In this embodiment, multiple guide ribs and the air outlet cover 2 are integrated into one structure and are manufactured by one-piece molding, which makes the overall structure of the air outlet cover 2 stronger and improves assembly efficiency. By setting multiple guide ribs on the inner surface of the protrusion 206, the air diffusion is finer and more dispersed, reducing the high-frequency noise generated by concentrated wind noise and achieving the effect of wind guidance and noise reduction.

[0103] In one embodiment, a first anti-foolproof positioning structure is provided between the air outlet cover 2 and the water baffle cover 3. The first anti-foolproof positioning structure is used to restrict the assembly direction during the assembly process of the air outlet cover 2 and the water baffle cover 3.

[0104] It should be noted that mistake prevention is a behavioral constraint method for prevention and correction. It uses restrictive methods to avoid errors, allowing operators to complete the correct operation without expending attention, experience, or professional knowledge.

[0105] The first foolproof positioning structure in this embodiment can guide and position the installation of the air outlet cover 2 and the water baffle cover 3, making it easier for users to identify the relative directions of the air outlet cover 2 and the water baffle cover 3 when installing them, so that the water baffle cover 3 can be installed more accurately on the top of the air outlet cover 2, improving installation efficiency and accuracy.

[0106] like Figure 2 and 5 As shown, in one embodiment, the first anti-mistake positioning structure includes at least one anti-mistake rib 401 and a first anti-mistake groove 402.
