Description

Technical Field

[0001] This utility model relates to the field of toilet technology, and in particular to a deodorizing and drying module and a smart toilet. Background Technology

[0002] There are two common drying and deodorizing solutions for existing smart toilets: One solution separates the drying and deodorizing modules. The drying function is achieved by a fan, a heating element, and a separate drying duct, while the deodorizing function is achieved by a separate fan, a deodorizing element, and a separate deodorizing duct. This solution uses two independent modules to achieve drying and deodorizing functions separately, resulting in cumbersome assembly and requiring significant space. The other solution shares a single fan for both drying and deodorizing functions. The airflow generated by the fan passes through two interconnected ducts, flowing through the heating element and the deodorizing element respectively. Forward rotation of the fan directs air towards the heating element for drying; reverse rotation draws air inward, directing it towards the deodorizing element for deodorization. This solution saves space compared to the first solution, but during deodorization, some polluted gas that hasn't been processed by the deodorizing module flows through the heating element, potentially causing odors during subsequent drying. Utility Model Content

[0003] The purpose of this utility model is to provide a deodorizing and drying module and a smart toilet to solve the problem that polluted gas flows through the heating element during deodorization and that odors are easily generated when the heating element is used for drying.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] The deodorizing and drying module includes a housing, a heating element, a drying baffle, a deodorizing element, and a bidirectional fan. The housing contains a drying duct and a deodorizing duct, which are separated from each other. The drying duct has a drying inlet and a drying outlet connecting to the outside of the housing. The deodorizing duct has a deodorizing outlet and a deodorizing inlet connecting to the outside of the housing. A connecting duct is also formed within the housing, connecting to the drying duct via the drying inlet and the deodorizing duct via the deodorizing outlet. The connecting duct has a ventilation opening connecting to the outside of the housing. The heating element is disposed within the drying duct. The drying baffle is disposed between the drying duct and the connecting duct, allowing air to flow only from the connecting duct to the drying duct. The deodorizing element is disposed within the deodorizing duct. The bidirectional fan is disposed within the connecting duct; when the bidirectional fan is turned off, the drying baffle is closed.

[0006] Optionally, the drying duct and the deodorizing duct are arranged vertically and vertically within the housing, the top of the drying baffle is rotatably mounted on the housing, and a drying limiting protrusion is provided on the side wall of the connecting duct. When the bidirectional fan is turned off, the drying baffle abuts against the drying limiting protrusion to disconnect the drying duct and the connecting duct.

[0007] Optionally, the housing includes an upper top plate, a lower bottom plate, and a partition plate. One end of the partition plate is connected to the lower bottom plate and divides the inner cavity of the housing into a first air duct and a second air duct that are spaced apart vertically. The second air duct is the drying air duct. The deodorizing air outlet is opened on the partition plate, and the deodorizing air inlet is opened on the lower bottom plate. The drying baffle divides the first air duct into the drying air duct and the connecting air duct.

[0008] Optionally, the deodorizing and drying module further includes a deodorizing baffle that is movably disposed within the deodorizing air duct, the deodorizing baffle only allowing air to flow from the deodorizing air inlet to the deodorizing air outlet.

[0009] Optionally, the top of the deodorizing baffle is rotatably connected to the housing, and a deodorizing limiting protrusion is provided around the side wall of the deodorizing air duct. The deodorizing baffle can abut against the deodorizing limiting protrusion to block the deodorizing air duct.

[0010] Optionally, when the bidirectional fan is turned off, the deodorizing baffle is in the open state.

[0011] Optionally, the cross-sectional area of ​​the drying air duct decreases at least partially from one end of the drying air inlet to one end of the drying air outlet.

[0012] Optionally, the cross-sectional area of ​​the deodorizing duct increases at least partially from one end of the deodorizing air outlet to one end of the deodorizing air inlet.

[0013] Optionally, the effective flow area of ​​the drying air duct is not less than the effective flow area of ​​the deodorizing air duct.

[0014] A smart toilet includes a smart toilet seat and the deodorizing and drying module described in any one of the above-mentioned embodiments, wherein the deodorizing and drying module is installed on the smart toilet seat.

[0015] The beneficial effects of this utility model are:

[0016] The deodorizing and drying module and the smart toilet including the deodorizing and drying module proposed in this utility model can prevent air from flowing in the drying air duct during deodorization. Thus, polluted gas will not flow through the heating element located in the drying air duct, solving the problem of odors easily generated when using the heating module for drying.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0028] This embodiment proposes a deodorizing and drying module and a smart toilet. The smart toilet includes the aforementioned deodorizing and drying module, a smart toilet seat, and a ceramic body. The smart toilet seat is movably mounted on the ceramic body, and the deodorizing and drying module is disposed on the smart toilet seat. (Reference) Figures 1-5 As shown, the deodorizing and drying module includes a housing 1, a heating element 2, a deodorizing element 3, a drying baffle 5, and a bidirectional fan 4. The housing 1 contains a drying duct 11 and a deodorizing duct 12, which are separated from each other and connected to the outside of the housing 1. The drying duct 11 has a drying inlet and a drying outlet 111, with the drying outlet 111 connecting the outside of the housing 1 to the drying duct 11. The heating element 2 is located at one end of the drying duct 11 near the drying outlet 111. The deodorizing duct 12 has a deodorizing inlet 121 and a deodorizing outlet 122, with the deodorizing inlet 121 connecting the outside of the housing 1 to the deodorizing duct 122. A deodorizing air duct 12 is formed inside the housing 1; a connecting air duct 13 is also formed inside the housing 1; a drying baffle 5 is movably disposed between the drying air duct 11 and the connecting air duct 13; the drying baffle 5 only allows air to flow from the connecting air duct 13 through the drying air inlet to the drying air duct 11; the connecting air duct 13 is connected to the deodorizing air duct 12 through the deodorizing air outlet 122; the connecting air duct 13 has a vent 131 that connects to the outside of the housing 1; a bidirectional fan 4 is disposed inside the connecting air duct 13; when the bidirectional fan 4 is closed, the drying baffle 5 is in the closed state, that is, the drying baffle 5 disconnects the connecting air duct 13 and the drying air duct 11.

[0029] like Figure 4As shown, during the drying operation, the bidirectional fan 4 rotates in the first direction. Air enters the connecting air duct 13 through the vent 131 and then flows through the drying air inlet to the drying air outlet 111. The drying baffle 5 allows air to flow through. After being heated by the heating element 2, the air flows out from the drying air outlet 111, thus drying the part to be dried. Figure 5 As shown, during deodorization, the bidirectional fan 4 rotates in the second direction, and the drying baffle 5 disconnects the drying duct 11 and the connecting duct 13. Air carrying polluted gas enters the deodorization duct 12 from the deodorization inlet 121, then is deodorized by the deodorizing component 3, and finally enters the connecting duct 13 from the deodorization outlet 122 and is discharged through the vent 131. During deodorization, the bidirectional fan 4 rotates in the second direction, and the drying baffle 5 disconnects the drying duct 11 and the connecting duct 13, thus preventing airflow within the drying duct 11. Polluted gas does not flow through the heating component 2, making it less likely to produce odors during subsequent drying operations. The first and second directions are opposite.

[0030] The heating element 2 and the deodorizing element 3 can each adopt any suitable structure with heating and deodorizing functions, without specific limitations. For example, the heating element 2 can be a mica heater formed by connecting a heating wire and a mica sheet, and the deodorizing element 3 can be a filter with a filter element.

[0031] refer to Figure 1 As shown, the drying duct 11 and the deodorizing duct 12 are arranged vertically and vertically within the housing 1, and the effective flow area of ​​the drying duct 11 is not less than the effective flow area of ​​the deodorizing duct 12 to improve drying efficiency. The top of the drying baffle 5 is provided with a rotating shaft, which is vertically inserted into the opposite side walls of the housing 1, thereby allowing the drying baffle 5 to be rotatably connected to the housing 1. A drying limiting protrusion 17 is provided on the side wall of the connecting duct 13. The drying limiting protrusion 17 facing the drying baffle 5 has a first inclined surface that gradually approaches the drying baffle 5 from top to bottom. When the bidirectional fan 4 is turned off, under the action of gravity, the drying baffle 5 abuts against the first inclined surface, thereby disconnecting the drying duct 11 and the connecting duct 13.

[0032] In other embodiments, the drying baffle 5 can also be kept in contact with the drying limiting protrusion 17 by means of an elastic element.

[0033] To increase the hot air velocity at the drying outlet 111 without changing the power of the bidirectional fan 4, and further improve drying efficiency, the cross-sectional area of ​​the drying duct 11 from one end to the drying inlet to the other end to the drying outlet 111 is at least partially reduced. Simultaneously, the cross-sectional area of ​​the deodorizing duct 12 from one end to the deodorizing outlet 122 to the other end to the deodorizing inlet 121 is at least partially increased, so as to absorb more polluted gas without changing the power of the bidirectional fan 4, thereby improving deodorization efficiency.

[0034] Specifically, the housing 1 includes an upper top plate 14, a lower bottom plate 15, a front side plate, a rear side plate, and a partition plate 16. The upper top plate 14, the lower bottom plate 15, the front side plate, and the rear side plate together enclose a cavity structure with openings at both ends. The upper top plate 14 extends from the end closest to the heating element 2 to the end furthest from the heating element 2. Figure 1 The bottom plate 15 gradually slopes upward from left to right. It includes a first plate 151 and a second plate 152. The first end of the second plate 152 is connected to the end of the first plate 151 away from the heating element 2, and the height of the first end of the second plate 152 is higher than the height of the first plate 151. The second plate 152 gradually slopes downward from the first end to the second end. The partition plate 16 is collinear with the second plate 152. Its first end is connected to the first end of the second plate 152 and extends inclinedly away from the second end of the second plate 152, thereby dividing and forming a first air duct and a second air duct that are spaced apart vertically within the housing 1. The deodorizing air outlet 122 is opened on the partition plate 16, and the deodorizing air inlet 121 is opened on the first plate 151. The second air duct is the drying air duct 11, and the first air duct is further divided into the drying air duct 11 and the connecting air duct 13 by the drying baffle 5. The opening of the housing 1 near the heating element 2 is the drying air outlet 111 of the drying air duct 11. Since the top plate 14 gradually tilts upward from the end closest to the heating element 2, while the second plate 152 tilts downward from the first end to the second end, the cross-sectional area of ​​the connecting air duct 13 gradually decreases from the end furthest from the drying air duct 11 to the end connected to the drying air duct 11, which further increases the airflow velocity during the drying operation and improves the drying effect.

[0035] More specifically, in order to fix the bidirectional fan 4 within the connecting duct 13, a first limiting plate is provided on the upper top plate 14 and / or the lower bottom plate 15 at a position corresponding to the connecting duct 13. The first limiting plate and the end face of the housing 1 away from the heating element 2 form a first limiting space, and the bidirectional fan 4 is fixedly assembled in the first limiting space. Similarly, in order to fix the heating element 2 within the drying duct 11, a second limiting plate is provided within the drying duct 11. The second limiting plate and the end of the housing 1 near the heating element 2 form a second limiting space, and the heating element 2 is fixedly assembled in the second limiting space. A third limiting plate is provided within the deodorizing duct 12. The third limiting plate and the first plate 151 cooperate to form a third limiting space, and the deodorizing element 3 is located within the third limiting space.

[0036] refer to Figure 2 and Figure 3As shown, the housing 1 includes a front housing 1 and a rear housing 1. The front housing 1 is detachably connected to the rear housing 1 by means including but not limited to bolts and snap-fit ​​connections to facilitate future maintenance. The front housing 1 includes a first upper top plate, a first lower bottom plate, and a rear side plate. The rear side plate includes a second upper top plate, a second lower bottom plate, and a front side plate. The first upper top plate and the second upper top plate are connected to form an upper top plate 14. The first lower bottom plate and the second lower bottom plate are connected to form a lower bottom plate 15. One of the front housing 1 and the rear housing 1 includes a partition plate 16, which is connected to the front side plate or the rear side plate.

[0037] In this embodiment, the deodorizing drying module also includes a deodorizing baffle 6 movably disposed within the deodorizing air duct 12. The deodorizing baffle 6 only allows air to flow from the deodorizing air inlet 121 to the deodorizing air outlet 122. When the deodorizing drying module performs drying operations, air flows from the connecting air duct 13 towards the drying air outlet 111 and tends to flow towards the deodorizing air inlet 121. Under the action of the airflow, the deodorizing baffle 6 blocks the deodorizing air duct 12, causing all the airflow generated by the bidirectional fan 4 to flow out from the drying air outlet 111, further improving the drying efficiency.

[0038] refer to Figure 1 As shown, the deodorizing baffle 6 is also rotatably connected to the top wall (partition plate 16) of the deodorizing air duct 12 via a rotating shaft. A deodorizing limiting protrusion 18 is arranged around the side wall of the deodorizing air duct 12. The deodorizing limiting protrusion 18 is located at the end of the deodorizing baffle 6 near the deodorizing air inlet 121, and the side of the deodorizing limiting protrusion 18 facing the deodorizing baffle 6 forms a second inclined surface that gradually moves away from the deodorizing baffle 6 from top to bottom. The deodorizing baffle 6 can abut against the second inclined surface to block the deodorizing air duct 12.

[0039] In this embodiment, when the bidirectional fan 4 is off, the deodorizing baffle 6 is in the open state under the action of gravity, that is, the deodorizing duct 12 is connected to the connecting duct 13. When the bidirectional fan 4 rotates in the first direction, the airflow generated by the bidirectional fan 4 applies a thrust to the deodorizing baffle 6, causing the deodorizing baffle 6 to abut against the deodorizing limiting protrusion 18, thereby sealing the deodorizing duct 12. It can be understood that when the deodorizing drying module performs deodorization operations, the gap between the deodorizing baffle 6 and the bottom wall (first plate 151) of the deodorizing duct 12 is larger than when the bidirectional fan 4 is off, resulting in a better deodorization effect.

[0040] Specifically, in order to improve the sealing between the deodorizing baffle 6 and the deodorizing limiting protrusion 18, the longitudinal section of the deodorizing limiting protrusion 18 located on the top wall of the deodorizing air duct 12 is set as L-shaped.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
