Description

Technical Field

[0001] The present invention relates to the field of sanitary ware, and particularly to an air outlet structure with a low-noise speed increasing function and a drying device for intelligent toilets. Background Art

[0002] The drying function has become a basic function of existing intelligent toilets. The specific drying method of the existing drying structure of intelligent toilets is as follows: After connecting a device that forms hot air at the end of the air inlet pipeline, it is blown out from the other end, and finally the buttocks are dried; The existing drying method has a simple structure and is easy to implement, but there are the following defects: (1) In order to prevent the buttocks from being scalded by hot air, the distance between the air outlet of the air inlet pipeline and the buttocks cannot be too close, and there is a certain distance between the two. However, when the existing hot air is discharged from the air outlet of the air inlet pipeline, it quickly diffuses around due to the loss of the restriction of the pipeline, resulting in insufficient wind force and low wind speed, and the fast drying effect cannot be achieved. Through market research and sales feedback, the existing drying efficiency is too low, and it requires a drying time of more than 4 minutes; In addition, during the slow drying process, the water on the buttocks is blown by low-speed hot air, forming a similar low-temperature steam, resulting in discomfort on the buttocks; (2) For the hot air entering the air inlet pipeline, the wind speed and potential energy of the hot air are bound to be gradually weakened in the pipeline, and the fast drying effect cannot be achieved, and the user experience is poor; (3) The air outlet noise is large, generating abnormal noises, affecting the user experience.

[0003] In summary, a structure that can improve the drying efficiency is needed to meet the use requirements. Summary of the Invention

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An air outlet structure with a low-noise speed increasing function, the air outlet structure includes a housing and a first air guiding unit;

[0007] The housing includes an air inlet, an air outlet and an air passage connecting the air inlet and the air outlet; The air passage is gradually tapered from the air inlet towards the air outlet;

[0008] The first air guiding unit is arranged at the air outlet, and an air flow accumulation area for making the air flow attach to the inner wall of the housing is formed between the first air guiding unit and the inner wall of the housing;

[0009] Wherein, the air flow enters from the air inlet, and after increasing the speed in the air flow accumulation area of the air passage, it is ejected from the air outlet.

[0010] Further, a fresh air hole is also formed on the housing, which is close to the air outlet and is arranged corresponding to the airflow accumulation area.

[0011] Further, the cross-sectional shapes of the air outlet of the housing and the first air guiding unit are elliptical; the first air guiding unit is installed in the air outlet of the housing through a connecting rib.

[0012] Further, an elliptical ring-shaped airflow accumulation area is formed between the housing and the first air guiding unit.

[0013] Further, one end of the first air guiding unit away from the air outlet forms a flat arc-shaped air guiding part.

[0014] Further, the connecting rib is an arc-shaped connecting rib.

[0015] A drying device for a smart toilet, which includes a mounting seat, a heating component, a blowing component and the air outlet structure as described above; the mounting seat is connected to the housing of the air outlet structure; the heating component and the blowing component are respectively installed in the mounting seat, and the heating component is arranged between the air outlet structure and the blowing component.

[0016] Further, the mounting seat is an arc-shaped mounting seat, and a second air guiding unit is arranged at the bending position of the arc-shaped mounting seat, which is used to guide the air blown out by the blowing component into the central part of the heating component.

[0017] Further, the second air guiding unit includes at least two air guiding plates; the two air guiding plates are attached to the inner side wall of the bending position of the mounting seat on the same side and in parallel, three air ducts are separated by the two air guiding plates, and the air passing area of the middle air duct is smaller than that of the other two air ducts.

[0018] Further, one side of the two air guiding plates is a connecting part, which is connected to the inner wall of the mounting seat; the other side of the air guiding plate is a free part, which extends radially and inwards along the mounting seat and crosses the axis of the mounting seat.

[0019] Further, the free part of the air guiding plate is an arc surface.

[0020] Further, the radian of the arc surface free part of the air guiding plate on the side close to the blowing component is smaller than that on the side close to the heating component.

[0021] Further, the blowing component is an axial flow fan.

[0022] Further, the air outlet direction of the air outlet structure is inclined upwards.

[0023] Further, the mounting base and the housing are hermetically mounted through a mortise connection structure; the mortise connection structure includes a mounting groove and a protruding portion, the mounting groove is opened on the end face of the housing facing the mounting base; the protruding portion is formed on the mounting base; wherein, the protruding portion is fitted into the mounting groove to make the mounting base and the housing hermetically and tightly matched.

[0024] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention provides an air outlet structure with a low-noise speed increasing function and a drying device for a smart toilet, which has a simple structure, reasonable design and is easy to implement, realizes the effect of accumulating air outlet, improves the drying efficiency, has low noise, and is easy to meet the user's usage experience; the air outlet structure adopted by the present invention is provided with a first air guiding unit at the air outlet, so that when the air flow passes through the first air guiding unit, an air flow gathering area will be formed, so that the air flow can still maintain the wind force for a certain distance when leaving the air outlet, improving the blowing effect; moreover, due to the continuous air flow, the air flow attenuation time can be extended; not only that, but also the noise can be greatly reduced. When the noise passes through the first air guiding unit, due to the gradually shrinking gap and the gradually enhanced diffuse reflection effect, the sound wave energy gradually weakens, and the noise can be basically eliminated (especially the low-frequency noise of 10-100HZ), achieving the effects of enhancing the wind force and reducing the noise;

[0026] 2. The present invention also sets fresh air holes in the air flow gathering area, and supplements new air into the air flow gathering area through the fresh air holes to form a diffuser effect, inhaling more air, and after micro-compression, the air flow velocity is increased, and the time for the attenuation of the high-speed air flow is extended;

[0027] 3. The present invention adopts an elliptical air outlet and a first air guiding unit, and an elliptical ring-shaped outlet is formed between the two. By using the cross-sectional area difference, the air forms micro-compression after passing through, and the flow velocity is greatly increased to form a high-speed air flow, so that a speed increasing effect is formed at the air outlet, further enhancing the wind force and realizing an efficient blowing or drying effect;

[0028] 4. The present invention sets the end of the first air guiding unit far from the air outlet into a flat arc-shaped air guiding part, so that the first air guiding unit has an elliptical conical structure. The arc transition is adopted to make the air flow flow smoothly, and it is not easy to cause energy loss due to hitting the corners, achieving the effects of good air flow fluidity and small energy loss;

[0029] 5. The present invention applies the air outlet structure to the drying device of the intelligent toilet, and at the same time sets the heating component between the blowing component and the air outlet structure. After the air enters the blowing component, it is heated by the heating component to form warm air, forming a concentrated and controllable warm air flow, avoiding the loss of flow velocity and heat of the warm air flow due to too long pipelines; at the same time, the heating component is set in the middle, and the temperature is easier to control and the temperature control is more accurate;

[0030] 6. The present invention sets the mounting seat in an arc shape, and a second air guiding unit is provided at the bending position, which not only extends the air passing distance, but also uses the arc-shaped wall surface to block the diffusion of noise, achieving the noise reduction effect. Moreover, it can also guide the air blown out by the blowing component forward and more concentratedly into the middle position of the heating unit, improving the air passing and heating efficiency.

[0031] 7. The second air guiding unit of the present invention is provided with at least two air guiding plates, and the air passing area of the middle air duct formed between the two air guiding plates is smaller than that of other air ducts. This structural design is ingenious, adopting a structure similar to a "fish fin", making the flow velocity through the middle air duct greater than that of other air ducts. Using Bernoulli's principle, the air flow is accelerated and concentrated towards the middle for rectification, forming a highly concentrated high-speed laminar air flow. At the same time, it can attract the air from other air ducts and quickly enter the middle part of the heating component. The air flow is more concentrated when passing through the heating component, so as to better heat and form warm air. In addition, it also has the effect of weakening noise, and the noise is easily in a diffuse reflection state when passing through, thus weakening the noise.

[0032] 8. One side of the air guiding plate of the present invention is a free part, so that the passing air encounters less air resistance, further accelerating the formation of a concentrated high-speed laminar air flow.

[0033] 9. The arc surface of the free part of the air guiding plate of the present invention is designed, and the radian on the side close to the blowing component is smaller than the radian on the side close to the heating component, so as to reduce air resistance, improve fluid performance and reduce energy loss.

[0034] 10. The blowing component of the present invention is an axial flow fan. The spiral wind (spiral air flow) generated by the axial flow fan can better flow through the middle air duct, better realizing the high-speed laminar air flow.

[0035] 11. The present invention sets the air outlet direction to be inclined upward, so that the air outlet direction fits better with the buttocks, and the air outlet accurately blows the moist part of the buttocks.

[0036] 12. The housing of the present invention and the assembly of the housing and the mounting seat both adopt a mortise connection structure for assembly. This method not only has a firm assembly, but also has a better sealing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] As Figures 1 to 4 shown, the present invention provides an air outlet structure with a low-noise speed increasing function, and the air outlet structure 1 includes a housing 2 and a first air guiding unit 3;

[0055] The housing 2 includes an air inlet 22, an air outlet 21 and an air passing channel 23 communicating the air inlet 22 and the air outlet 21; the air passing channel 23 is tapered from the air inlet 22 towards the air outlet 21; (it should be noted that the housing 2 of the present invention is separately provided (as Figure 10 shown), and is divided into a first outer shell 2A and a second outer shell 2B, and the first and second outer shells 2A and 2B are tightly fitted through a mortise connection structure 20);

[0056] The cross-sectional shapes of the air outlet 21 of the housing 2 and the first air guiding unit 3 are elliptical; the first air guiding unit 3 is installed in the air outlet 21 of the housing 2 through a connecting rib 4; the connecting rib 4 is an arc-shaped connecting rib 4;

[0057] The first air guiding unit 3 is arranged at the air outlet 21, and an air flow accumulation area 24 for making the air flow adhere to the wall is formed between the first air guiding unit 3 and the inner wall of the housing 2; one end of the first air guiding unit 3 far from the air outlet 21 forms a flat arc-shaped air guiding part 30;

[0058] A fresh air hole 20 is further opened on the housing 2, and the fresh air hole 20 is close to the air outlet 21 and is arranged corresponding to the air flow accumulation area 24;

[0059] Among them, the air flow enters from the air inlet 22, and after accelerating in the air accumulation area 24 of the air passage 23, it is ejected from the air outlet 21.

[0060] More specifically, an elliptical annular air accumulation area 24 is formed between the housing 2 and the first air guiding unit 3.

[0061] Embodiment 1, as Figures 1 to 6 shown, the present invention takes a drying device for a smart toilet as an example. The drying device includes a mounting seat 5, a heating component 6, a blowing component 7 and an air outlet structure 1; the air outlet structure 1 mainly includes the following components: a housing 2, a first air guiding unit 3 and a connecting rib 4;

[0062] The mounting seat 5 is mounted to the housing 2 of the air outlet structure 1 (it should be noted that the mounting seat 5 and the outer housing 2 are hermetically mounted through a mortise connection structure 9; the mortise connection structure includes a mounting groove 91 and a protrusion 92. The mounting groove 91 is opened on the end face of the housing 2 facing the mounting seat 5; the protrusion 92 is formed on the mounting seat 5; wherein, the protrusion 92 is fitted into the mounting groove 91 to make the mounting seat 5 and the outer housing 2 hermetically and tightly fitted); the heating component 6 and the blowing component 7 are respectively mounted in the mounting seat 5, and the heating component 6 is arranged between the air outlet structure 1 and the blowing component 7; the air outlet direction of the air outlet structure 1 is inclined upward.

[0063] Actual assembly and working principle: The drying device includes two parts:

[0064] As Figure 5 shown, the front part is the air outlet structure 1, and the rear part is the blowing component 7 and the heating component 6. The housing 2 of the air outlet structure 1 is docked with the mounting seat 5 provided with the blowing component 7 and the heating component 6; the blowing component 7 is mounted at the end of the mounting seat 5, and the heating component 6 is located between the blowing component 7 and the air outlet structure 1; wherein, in this embodiment, the blowing component 7 adopts a high-speed axial flow fan, and the heating component 6 adopts an electric heating wire. The above blowing component 7 and heating component 6 are not limited in the present invention, and components with the same function belong to the protection scope of the present invention; when the drying function is turned on, air is inhaled into the air duct of the mounting seat 5 through the axial flow fan 7 and heated by the electric heating wire 6 to form warm air. The use of the axial flow fan 7 and the electric heating wire 6 can quickly form warm air and can instantaneously heat the air to about 50°C within a few seconds. In addition, the air type at the air outlet 21 of the axial flow fan 7 is spiral, forming a high-speed warm current; while the front air outlet structure 1 optimizes the air flow, and finally blows out a continuous high-speed, controllable and concentrated warm air flow; compared with the drying device of the traditional smart toilet, the heat of the warm air in the above way is not easily lost, and the air flow velocity is not easily weakened.

[0065] The warm air enters from the air inlet 22 of the housing 2 of the air outlet structure 1;

[0066] The housing 2 forms an air inlet 22, an air outlet 21, and an air passage 23 connecting the air inlet 22 and the air outlet 21, and the air passage 23 is tapered from the air inlet 22 towards the air outlet 21; at the air outlet 21, a first air guiding unit 3 is arranged through a connecting rib 4, and the connecting rib 4 is an arc-shaped connecting rib 4, so that the air outlet 21 becomes an annular air outlet 21. In this way, when the warm current passes through the air passage 23, it is slightly compressed, the flow rate is greatly increased, and a high-speed warm air flow is formed; in this embodiment, the air outlet 21 of the housing 2 is set to have an elliptical cross-sectional shape with the first air guiding unit 3, so that the air outlet 21 becomes an elliptical ring, so that the potential energy of the air flow passing through is not easily reduced; when the spacing width of the elliptical annular air outlet 21 of the present invention is between 2 mm and 3.5 mm, the controllability and stability of the air flow at the air outlet 21 are relatively high;

[0067] An air flow accumulation area 24 for making the air flow adhere to the wall is formed between the first air guiding unit 3 and the inner wall of the housing 2; one end of the first air guiding unit 3 far from the air outlet 21 forms a flat arc-shaped air guiding part 30; a fresh air hole 20 is also opened on the housing 2, and the fresh air hole 20 is close to the air outlet 21 and is arranged corresponding to the air flow accumulation area 24;

[0068] When the warm current enters the air passage 23 from the air inlet 22, the warm current enters the air flow accumulation area 24 formed between the first air guiding unit 3 and the inner wall of the housing 2 after reaching the arc-shaped air guiding part 30. The warm current in the air flow accumulation area 24 will flow along the surface of the first air guiding unit 3. The air flow accumulation area 24 is the Stokes area. The principle is that when the Reynolds number is less than or equal to 1, the viscous force on the surface of the object dominates the air flow to adhere to the surface of the first air guiding unit 3 similar to an elliptical cone. When approaching the air outlet 21, the air flow speed increases, and when leaving the bottom surface of the elliptical cone, the Reynolds number increases, the air flow symmetry is lost, a von Kármán vortex street is formed, and the air pressure at the first air guiding unit 3 of the elliptical cone drops rapidly, the air flow shrinks and converges, and the directivity is enhanced; in addition, more air is inhaled by using the fresh air hole 20 opened on the housing 2 (4 fresh air holes 20 are arranged in this embodiment, symmetrically arranged at the upper and lower positions of the housing 2). After inhaling air in the air flow accumulation area 24, a diffuser effect will be formed, increasing the high-speed air flow rate and extending the attenuation time of the high-speed air flow. In this way, a directional air flow can be formed after the spiral warm air passes through the air outlet structure 1. At the same time, the warm current can still maintain a strong wind force after leaving the air outlet 21, and cooperate with the upwardly inclined air outlet direction to achieve the effect of quickly drying the buttocks;

[0069] Embodiment 2, as Figures 7 to 9As shown, the same parts in the second embodiment and the first embodiment will not be repeated here. The difference lies in the mounting seat 5. By modifying the structure of the mounting seat 5, the air passing, the rapid formation of warm air, and the noise reduction (cooperating with the noise reduction function of the air outlet structure to achieve secondary noise reduction, that is, effectively reducing or eliminating low-frequency noise of 10 - 200HZ) effects are further improved;

[0070] Actual assembly and working principle: This drying device includes two parts:

[0071] As Figure 5 shown, the front part is the air outlet structure 1, and the rear part is the mounting seat 5, the heating component 6, and the blowing component 7;

[0072] The part of the air outlet structure 1 is the same as that in the first embodiment and will not be described in detail. The main difference lies in the part of the mounting seat 5 at the rear;

[0073] The housing 2 of the air outlet component 1 is docked with the mounting seat 5 where the blowing component 7 and the heating component 6 are installed; the blowing component 7 is installed at the end of the mounting seat 5, and the heating component 6 is located between the blowing component 7 and the air outlet structure 1; among them, in this embodiment, the blowing component 7 uses a high-speed axial flow fan, and the heating component 6 uses an electric heating wire. The above blowing component 7 and heating component 6 are not limited in the present invention, and components with the same function belong to the protection scope of the present invention; when the drying function is turned on, air is inhaled into the air duct of the mounting seat 5 through the axial flow fan 7 and heated by the electric heating wire 6 to form warm air. Using the axial flow fan 7 and the electric heating wire 6 can quickly form warm air and can instantaneously heat the air to about 50°C within a few seconds. In addition, the air flow pattern at the air outlet 21 of the axial flow fan 7 is spiral, forming a high-speed warm current; and the air outlet structure 1 at the front part optimizes the air flow, and finally blows out a continuous high-speed, controllable and concentrated warm air stream; compared with the drying device of the traditional intelligent toilet, the heat of the warm air in the above method is not easily lost, and the air flow rate is not easily weakened;

[0074] Among them, a second air guiding unit 8 is also provided between the blowing component blowing the wind of the axial flow fan 7 into the heating wire 6;

[0075] During actual preparation and use, the mounting seat 5 is an arc-shaped mounting seat 5, and a second air guiding unit 8 is provided at the bending position of the arc-shaped mounting seat 5, which is used to guide the wind blown out by the blowing component 7 into the central part of the heating component 6;

[0076] The second air guiding unit 8 includes at least two air guiding plates 81 and 82; the two air guiding plates 81 and 82 are attached to the inner side wall of the bending position of the mounting seat 5 on the same side and in parallel, and three air ducts 83, 84, and 85 are separated by the two air guiding plates 81 and 82, and the air passing area of the middle air duct 83 is smaller than that of the other two air ducts 84 and 85; it should be noted that one side of the two air guiding plates 81 and 82 is the connecting part 810 and 820, which is connected to the inner wall of the mounting seat 5; the other side of the air guiding plates 81 and 82 is the free part, which extends radially and inwards along the mounting seat 5 and crosses the axis A of the mounting seat 5.

[0077] In order to improve the air guiding effect and reduce energy loss, the free parts of the air guiding plates 81 and 82 are designed as arc surfaces in the present invention, and the radian of the side close to the blowing component B is smaller than that of the side close to the heating component C; it should be noted that the smaller here means that the radian is more gentle;

[0078] During use, the axial flow fan sucks in air to form a spiral air flow, and then enters through the middle air duct 83 formed between the two air guiding plates 81 and 82. Of course, part of the air also enters through the upper and lower air ducts 84 and 85 outside the middle air duct 83. However, due to the small spacing of the middle air duct 83, the air flow is accelerated and rectified by using Bernoulli's principle to form a high-concentration high-speed laminar air flow. The air flow velocity of the middle air duct 83 is faster than that of the other air ducts 84 and 85. When blowing air towards the heating wire 6, it attracts the air flow of the other air ducts 84 and 85 and quickly blows it concentratedly into the middle of the heating wire 6, thereby better heating it into warm air; it should be noted that generally, the inner diameter of the mounting seat 5 is 29.3 mm, and the spacing of the middle air duct 83 is preferably 6 mm, and the noise reduction effect is better when it is between 5 and 8 mm; during this process, due to the arc surface design of the free parts of the air guiding plates 81 and 82, not only is it easier for the spiral air to enter the middle air duct 83, but also the air resistance is small. Compared with the triangular and trapezoidal air guiding plates 81 and 82 through wind speed testing, the air resistance is greatly reduced; in addition, the arc transition on the side B close to the axial flow fan is gentler than that on the other side C, increasing the contact time and angle with the air flow. Combined with the circular air duct, it is easier to form a high-concentration laminar flow.

[0079] Not only that, the wind noise generated by the axial flow fan 7 is easily in a diffuse reflection state when passing through the second air guiding unit 8, thereby weakening the noise. Cooperating with the arc-shaped mounting seat 5, the curved wall surface can well block the diffusion of noise;

[0080] The warm air passing through the heating wire plays a good role in drying and noise reduction when passing through the aforementioned air outlet structure, and it is easy to meet the usage requirements of users.

[0081] The descriptions of the above-mentioned specification and embodiments are used to explain the protection scope of the present invention, but do not constitute a limitation to the protection scope of the present invention. Modifications, equivalent substitutions or other improvements to the embodiments of the present invention or some of its technical features obtained by those of ordinary skill in the art through logical analysis, reasoning or limited experiments in combination with common general knowledge, ordinary technical knowledge in the field and / or the prior art under the inspiration of the present invention or the above-mentioned embodiments shall all be included within the protection scope of the present invention.
