Description

TECHNICAL FIELD

[0001] The present application relates to a drying device of a smart toilet, and more particularly, to a drying device of a smart toilet which can be adjusted in extension and retraction and is heat-insulated. BACKGROUND

[0002] With the popularization and application of smart toilets, more and more consumers pursue the functional experience of smart toilets, and the drying function of a smart toilet is a representative function of the increasing demand of consumers for smart toilets. The conventional drying device of a smart toilet is mainly fixed, and the drying performance thereof cannot achieve the drying effect expected by consumers. With the continuous improvement of the functional experience of smart toilets, a toilet with an air outlet pipeline of a drying device which can be adjusted in extension and retraction has appeared.

[0003] The air outlet pipeline of a smart toilet can be moved and adjusted in extension and retraction, which can improve the functional experience of a smart toilet and improve the drying effect, but also brings problems. That is, in a long hot air blowing process, the moving air duct and the high-temperature airflow inside the pipeline achieve thermal equilibrium, resulting in a very high temperature of the surface of the moving air duct. If the surface of the human body accidentally contacts the surface of the moving air duct during work or immediately after work, there is a risk of scalding. Therefore, how to avoid this risk is a very realistic problem. SUMMARY

[0004] In view of the above problems, the main purpose of the embodiments of the present application is to provide a drying device and a smart toilet. In a toilet drying device with an air outlet passage which can be moved and adjusted in extension and retraction, a heat-insulating structure is arranged at one end of the moving air duct close to the air outlet and on the upward side of the outer wall of the moving air duct. The heat-insulating plate moves in extension and retraction with the moving air duct, and can effectively isolate the high temperature of the outer surface of the moving air duct caused by long-time hot air drying work of the moving air duct, thereby avoiding the user from being scalded by accidentally contacting the moving air pipe.

[0033] ​​​​​In order to make the purposes, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0034] Referring to Figures 1-15 the structural schematic diagram of the drying device of the embodiments of the present application. The drying device of the present application is applicable to a smart toilet, but is not limited to a smart toilet.

[0035] Figures 1-4 the appearance structural schematic diagram of the drying device of an embodiment of the present application. Figure 5 the exploded structural schematic diagram of the drying device of Figure 1 . Figure 6 the cross-sectional structural schematic diagram of the drying device of Figure 1 . As shown in Figures 5-6 , the embodiments of the present application provide a drying device, which comprises an air duct body 1, a movable air duct 2 and a heat insulation plate 3; the air duct body 1 is configured in a cylindrical shape; the movable air duct 2 is configured in a cylindrical shape, the air duct body 1 is sleeved on the movable air duct 2, the movable air duct 2 can slide relative to the air duct body 1, and one end of the movable air duct 2 away from the air duct body 1 is provided with an air outlet 21; the heat insulation plate 3 is arranged at one end of the movable air duct 2 close to the air outlet 21 and located on the upward side of the outer wall of the movable air duct 2. Figures 1-4 and Figure 6 , the movable air duct 2 extends into the air duct body 1, and the movable air duct 2 extends into the air duct body 1 in the initial state or after drying is completed. Figure 7 , the movable air duct 2 extends out of the air duct body 1. Figure 8 , the cross-sectional structural schematic diagram of the drying device of Figure 7 is shown, Figure 8 the arrows indicate the flow direction of the warm air flow inside the air duct body 1 and the movable air duct 2, and the warm air flow finally flows out through the air outlet 21. Figure 9 the cross-sectional structural schematic diagram of the drying device of Figure 7 . Figure 10 the cross-sectional structural schematic diagram of the drying device of Figure 9 , which shows that the heat insulation plate 3 is arranged at one end of the movable air duct 2 close to the air outlet 21 and located on the upward side of the outer wall of the movable air duct 2.

[0036] Specifically, during the drying operation of the drying device, the movable air duct 2 needs to move out of the air duct body 1 to output warm air, and the output drying warm air is adjusted according to the use requirement. Assuming that the required air temperature contacting the human body is 45℃, the warm air output by the heating assembly of the drying device is sent to the surface of the human body through the air duct body 1, the movable air duct 2 and the air outlet 21, and the temperature of the warm air is reduced during the whole process. The user requires an air temperature of 45℃, and the air temperature generated at the output starting end and inside the air duct is basically about 70℃. During the long-time output process through the air duct, the inside and outside of the air duct will form a temperature balance (constant temperature state). At this time, if the human body accidentally contacts the extended movable air duct 2, it is possible to be scalded.

[0037] Notably, the drying device described in the embodiments of the present application is provided with a movable air duct 2 that can be telescopically moved relative to the air duct body 1, and a heat insulation plate 3 is arranged on the side of the outer wall of the movable air duct 2 facing upward. When the movable air duct 2 is extended, the heat insulation plate 3 is adjacent to or in contact with the surface of the human body. The drying device of the present application can reduce the temperature of the position where the movable air duct 2 has a probability of contacting the surface of the human body during the moving drying operation, thereby preventing the user from being accidentally scalded by the relatively hot movable air duct 2.

[0038] In addition, the drying device of the present application is provided with a heat insulation plate 3 arranged at one end of the movable air duct 2 close to the air outlet 21 and on the side of the outer wall of the movable air duct 2 facing upward. The heat insulation plate 3 telescopically moves in the air duct body 1 along with the movable air duct 2, does not occupy the space of the closestool, has a simple structure and is convenient for popularization and application.

[0039] In one exemplary embodiment, as shown in Figure 10 the heat insulation plate 3 includes a plate body 31; the plate body 31 includes a first plate face 311 facing the inner cavity of the movable air duct 2, and the first plate face 311 and the outer wall of the movable air duct 2 have a gap 4 therebetween.

[0040] Specifically, the gap 4 is arranged between the first plate face 311 and the outer wall of the movable air duct 2, and the gap 4 is an air spacing layer, which can effectively isolate the heat flowing from the inner cavity of the air duct body 1 and the movable air duct 2 to the upper part of the outer wall near the air outlet 21 of the movable air duct 2, and reduce the heat conduction temperature of the upper part of the outer wall near the air outlet 21 of the movable air duct 2. That is, the gap 4 arranged between the first plate face 311 and the outer wall of the movable air duct 2 can more effectively prevent the user from being scalded by the upper surface of the movable air duct 2 extended out of the air duct body 1.

[0041] In one exemplary embodiment, the width H of the gap 4 is 0.5mm-3mm.

[0042] Specifically, due to the structural space limitation of the intelligent toilet, the heat insulation plate 3 cannot occupy additional space of the drying device, but the heat insulation plate 3 should also have effective heat insulation and cooling effects. Therefore, as shown in Figure 10 According to actual design experience, the width H of the gap 4 is set to be 0.5mm-3mm. Of course, if the space of the intelligent toilet is sufficient, the larger the width H of the gap 4, the better the heat insulation effect of the air gap layer.

[0043] In an exemplary embodiment, as shown in Figures 12-13 The heat insulation plate 3 further includes a protruding part 32 arranged on the first plate surface 311, and an end of the protruding part 32 away from the first plate surface 311 abuts against the outer wall of the moving air duct 2.

[0044] Specifically, the protruding part 32, the first plate surface 311 and the outer wall of the moving air duct 2 enclose the gap 4 having heat insulation and cooling effects.

[0045] In an exemplary embodiment, as shown in Figure 12 The protruding part 32 is configured as a strip-shaped protrusion extending along the edge of the first plate surface 311.

[0046] Specifically, the protruding part 32 is configured as a strip-shaped protrusion extending along the edge of the first plate surface 311, so as to maximize the space of the gap 4, and make the heat insulation and cooling effects of the gap 4 best.

[0047] In an exemplary embodiment, as shown in Figure 13 The protruding part 32 is provided with two, and the two protruding parts 32 are arranged on opposite sides of the first plate surface 311 respectively, and the moving air duct 2 includes two vertically arranged side wall parts 22, and the two protruding parts 32 are connected to the two side wall parts 22 respectively along the length direction of the moving air duct 2.

[0048] Specifically, Figure 13 As shown in the cross-sectional structure diagram of the drying device, the two protruding parts 32 are arranged on opposite sides of the first plate surface 311 respectively, and the two protruding parts 32 are connected to the two side wall parts 22 respectively along the length direction of the moving air duct 2, which can maximize the space of the gap 4 so that the upper side of the end of the moving air duct 2 close to the air outlet 21 can be cooled and insulated more effectively. Moreover, the two protruding parts 32 of the heat insulation plate 3 are connected to the side wall parts 22 of the moving air duct 2, which can further reduce the efficiency of heat conduction of the high-temperature airflow in the cavity of the moving air duct 2 to the heat insulation plate 3; at the same time, the area of the side wall parts 22 of the moving air duct 2 is utilized to increase the loss of heat on the moving air duct 2 in the heat conduction process. In this way, the heat insulation plate 3 is supported in structure while ensuring the heat insulation and cooling functions of the heat insulation plate 3 with the smallest contact area and the lowest thermal conductivity.

[0049] Preferably, the thickness L2 of the side wall portion is greater than the thickness L1 of the protruding portion, so that the connection between the heat insulation plate 3 and the moving air duct 2 is stable and firm, and the heat transferred to the protruding portion 32 through the side wall portion 22 is small.

[0050] In an exemplary embodiment, as shown in Figure 12 and Figures 14-15 shown, the first plate surface 311 is provided with a first buckle 33 on one side close to the air duct body 1, and the moving air duct 2 is provided with a first clamping hole 23, the first buckle 33 passes through the first clamping hole 23 and hooks the edge of the first clamping hole 23.

[0051] Specifically, Figure 12 is a schematic diagram of the three-dimensional structure of the heat insulation plate 3 of an embodiment of the present application, which shows the structural composition of the side of the heat insulation plate 3 facing the moving air duct 2. Figure 12 In the embodiment shown, the first buckle 33 is provided at one end of the heat insulation plate 3 and is arranged as two spaced apart. Of course, the first buckle 33 can also be provided as one, three or more. As shown in Figure 5 is a schematic diagram of the structure of the drying device, the moving air duct 2 is provided with two first clamping holes 23, and the two first clamping holes 23 and the two first buckles 33 are respectively arranged in position, and the two first clamping holes 23 and the two first buckles 33 are respectively buckled together during assembly.

[0052] In an exemplary embodiment, as shown in Figure 15 , the first buckle 33 includes a first clamping hook 331 away from the first plate surface 311, and a first connecting portion 332 extending from the first plate surface 311 and connected to the first clamping hook 331, the first connecting portion 332 passes through the first clamping hole 23, and the first clamping hook 331 abuts the inner wall of the moving air duct 2;

[0053] The first clamping hook 331 includes a first side surface 3311 away from the first plate surface 311, and the first side surface 3311 and the inner wall 24 of the moving air duct 2 are smoothly transitioned.

[0054] Specifically, the heat insulation plate 3 and the moving air duct 2 are fixed by buckle connection, which is simple in structure and convenient to disassemble and assemble. Of course, the heat insulation plate 3 and the moving air duct 2 can also be connected and fixed by other ways. The first side surface 3311 of the first clamping hook 331 away from the first plate surface 311 is smoothly transitioned with the inner wall 24 of the moving air duct 2, which can reduce the fluid resistance in the working process of the air duct. That is, as shown in Figure 15 , the inner wall 24 of the moving air duct 2 and the first clamping hook 331 are designed as a bevel structure near the first clamping hook 331, so that the outer surface of the bevel structure and the first side surface 3311 of the first clamping hook 331 are smoothly transitioned and connected.

[0055] In an exemplary embodiment, as shown in Figures 10-12As shown, the first plate surface 311 is provided with a second buckle 34 away from one side of the air duct body 1, and the movable air duct 2 is provided with a second clamping hole 25, the second buckle 34 is clamped through the second clamping hole 25 and hooks the edge of the second clamping hole 25.

[0056] Specifically, Figure 12 The second buckle 34 of the heat insulation plate 3 in the embodiment shown is arranged on the first plate surface 311 and at the end opposite to the first buckle 33. Figure 12 In the embodiment shown, the second buckle 34 is arranged as one. Of course, the second buckle 34 can also be arranged as multiple. For example, Figure 5 The structure diagram of the drying device shown, the movable air duct 2 is provided with one second clamping hole 25, the second clamping hole 25 and the second buckle 34 are arranged in position respectively, and the second clamping hole 25 and the second buckle 34 are buckled together in correspondence when assembled.

[0057] In an exemplary embodiment, as shown, Figure 11 As shown, the second buckle 34 includes a second hook 341 away from the first plate surface 311, and a second connecting portion 342 extending from the first plate surface 311 and connected to the second hook 341, the second connecting portion 342 is clamped through the second clamping hole 25, and the second hook 341 abuts against the inner wall of the movable air duct 2; the second hook 341 includes a second side surface 3411 away from the first plate surface 311, and the second side surface 3411 and the inner wall 24 of the movable air duct 2 are smoothly transitioned.

[0058] Specifically, the heat insulation plate 3 and the movable air duct 2 are fixed by buckle connection, which is simple in structure and convenient to disassemble and assemble. Of course, the heat insulation plate 3 and the movable air duct 2 can also be connected and fixed by other ways. The second side surface 3411 of the second hook 341 away from the first plate surface 311 is smoothly transitioned with the inner wall 24 of the movable air duct 2, which can reduce the fluid resistance in the working process of the air duct. That is, Figures 10-11 As shown, the inner wall 24 of the movable air duct 2 is designed as a bevel structure near the second hook 341, so that the outer surface of the bevel structure is smoothly transitioned and connected with the second side surface 3411 of the second hook 341.

[0059] It is worth noting that, Figure 10 , Figure 12 and Figure 15 As shown in the embodiment of the drying device, the opening directions of the first buckle 33 and the second buckle 34 are opposite, so that the heat insulation plate 3 and the movable air duct 2 are more firmly connected and fixed.

[0060] In an exemplary embodiment, as shown, Figure 7 and Figures 10-11 The plate body 31 also includes a second plate surface 312 away from the inner cavity of the movable air duct 2, and the second plate surface 312 is flush with the outer wall of the movable air duct 2.

[0061] Specifically, in order to ensure that the appearance of the drying device is neat and tidy and does not occupy additional space of the intelligent toilet, while ensuring the integrated design of the shape of the movable air duct 2, the heat insulation plate 3 is connected to the movable air duct 2 in a design connection structure. After the heat insulation plate 3 is connected and fixed to the movable air duct 2, the parts of the movable air duct 2 and the heat insulation plate 3 located in the heat flow cavity of the drying device adopt an overall over-arc surface and a beveled smooth transition design, which can not only ensure smooth connection of the connecting surface, but also reduce the resistance suffered by the heat flow gas circulation.

[0062] In an exemplary embodiment, as shown in Figures 1-9 , the drying device further comprises a heating assembly 5 and a fan 6, one end of the heating assembly 5 is in communication with the end of the air duct body 1 away from the movable air duct 2, and the air outlet 61 of the fan 6 is in communication with the other end of the heating assembly 5.

[0063] Specifically, the fan 6 is used to produce airflow, and the heating assembly 5 is used to heat the airflow output from the air outlet 61 of the fan 6.

[0064] In an exemplary embodiment, as shown in Figure 5 and Figure 7 , the drying device further comprises a driving assembly 7, the driving assembly 7 comprises a motor 71 and a transmission gear set 72 arranged on the side surface of the air duct body 1, and a transmission member (not shown in the figure) arranged on the movable air duct 2.

[0065] The motor 71 drives the transmission gear set 72 to rotate, and the transmission gear set 72 drives the transmission member to move, so that the movable air duct 2 slides in the air duct body 1.

[0066] Specifically, the transmission member can be a rack fixedly arranged on the movable air duct 2, and the rack is arranged in meshing transmission with the transmission gear set 72, so that the rack and the movable air duct 2 move together relative to the air duct body 1.

[0067] Notably, when the driving assembly 7 is arranged on one side of the drying device, the overall occupied space of the drying device can be saved, and the module matching performance of the drying device can be improved.

[0069] Specifically, the support 8 is used to connect the drying device and the intelligent toilet together, and the support 8 has the effect of making the structure of the drying device more firm and stable.
