Description

Technical Field

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

[0002] Smart toilets typically come equipped with deodorizing and drying functions to enhance user comfort. The drying function requires sufficient airflow to quickly dry the body, while the deodorizing function only needs to drive airflow to expel odors or purify them through a deodorizing component, without requiring strong airflow. Therefore, the airflow required for drying is usually much greater than that required for deodorizing.

[0003] Currently, there are two main ways to implement the deodorizing and drying functions of toilets. One method is to set up separate air ducts and fans for the deodorizing and drying functions, so that they do not interfere with each other. However, the air volume of the drying fan is relatively small, resulting in poor drying effect. The other method is to share the air duct and fan for the deodorizing and drying functions. The deodorizing or drying functions are achieved by controlling the forward and reverse rotation of the fan. The fan is an axial flow fan. When the axial flow fan rotates forward, it can generate a large air volume for drying. However, when it rotates in reverse, the air volume generated is too small to effectively achieve the deodorizing function. Utility Model Content

[0004] The purpose of this utility model is to provide a drying and deodorizing module and a toilet to solve the problem of insufficient air volume for drying or deodorizing existing toilets.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] In a first aspect, the present invention provides a drying and deodorizing module, including a first fan, a second fan, and a connecting duct. The second fan has a first air outlet, a second air outlet, and a third air outlet. The first air outlet and the second air outlet are arranged opposite each other along the fan axis of the second fan, and the axis of the third air outlet is arranged at an angle to the fan axis of the second fan. The connecting duct connects the air outlet of the first fan and the first air outlet.

[0007] In one embodiment, the drying and deodorizing module further includes a drying duct that connects to the third air outlet of the second fan.

[0008] In one embodiment, a blocking element is provided in the drying duct, which only allows airflow from the end of the drying duct where the second fan is located to the end of the drying duct away from the second fan.

[0009] In one embodiment, the blocking member includes a baffle and a blocking part. The baffle is hinged within the drying duct, and the blocking part is disposed on the side of the baffle near the second fan to restrict the baffle from rotating toward the second fan. The baffle can abut against the blocking part to disconnect the two ends of the drying duct.

[0010] In one embodiment, the blocking portion is a blocking protrusion formed on the inner wall of the drying duct; or, the second fan is at least partially located inside the drying duct, and the blocking portion is the fan housing of the second fan. In one embodiment, the drying and deodorizing module further includes a heating element disposed on the third air outlet side of the second fan.

[0011] In one embodiment, the drying and deodorizing module further includes a deodorizing air duct that is connected to the air inlet of the first fan.

[0012] In one embodiment, the drying and deodorizing module further includes a deodorizing component disposed on the air inlet side of the first fan.

[0013] Secondly, this utility model provides a toilet, including a toilet body and a drying and deodorizing module as described in any of the above claims, wherein the drying and deodorizing module is disposed on the toilet body.

[0014] The beneficial effects of this utility model are:

[0015] When the above-mentioned drying and deodorizing module is deodorizing, the first fan is turned on. Compared with the method of using an axial flow fan in reverse, the air volume of the separately set first fan is large enough to effectively deodorize. When drying, the first fan and the second fan work together, the fan utilization rate is high, and the air volume formed by the two is large, resulting in a good drying effect.

[0028] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] refer to Figures 1-8 As shown, an embodiment of this utility model provides a drying and deodorizing module, including a connecting duct 3, a first fan 1 and a second fan 2. The second fan 2 has a first air outlet 2a and a second air outlet 2b arranged opposite to each other along the fan axis of the second fan 2, and a third air outlet 2c whose axis is arranged at an angle to the fan axis of the second fan 2. The connecting duct 3 connects the air outlet of the first fan 1 and the first air outlet 2a.

[0033] During deodorization, the first fan 1 is turned on while the second fan 2 is turned off. The odorous gas passes through the first fan 1 and the connecting duct 3, and then enters the second fan 2 through the first air outlet 2a. According to Bernoulli's principle, the odorous gas is preferentially discharged from the second air outlet 2b, which is opposite to the first air outlet 2a, thus achieving the deodorization function. During drying, both the first fan 1 and the second fan 2 are turned on. At this time, both the first air outlet 2a and the second air outlet 2b are air inlets, meaning that the second fan 2 can achieve double-sided air intake. One airflow, under the action of the first fan 1, flows through the connecting duct 3, then through the first air outlet 2a, enters the second fan 2, and exits from the third air outlet 2c. The other airflow enters the second fan 2 through the second air outlet 2b and also exits from the third air outlet 2c. The airflow exiting from the third air outlet 2c can dry the object.

[0034] The aforementioned drying and deodorizing module connects the first fan 1 and the second fan 2 via connecting duct 3, and the second fan 2 is configured to be capable of bi-directional air intake. For example... Figure 5 As shown, during deodorization, the first fan 1 is turned on. Compared to using an axial fan in reverse, the airflow from the separately set first fan 1 is large enough to effectively deodorize; and as... Figure 6 As shown, during drying, the first fan 1 and the second fan 2 work together, resulting in high fan utilization and an air volume far exceeding that of a separately installed drying fan in the background technology, leading to better drying effect. It is understood that the first fan 1 can be either a centrifugal fan or an axial fan, while the second fan 2 is clearly a double-sided centrifugal fan.

[0035] In some embodiments, the power of the second fan 2 is greater than that of the first fan 1. Therefore, the noise generated by the first fan 1 is also less than that of the second fan 2. Compared with turning on the second fan 2 alone, turning on the first fan 1 and the second fan 2 at the same time will not significantly increase the noise, thus ensuring the user's experience.

[0036] refer to Figure 9 As shown, an embodiment of this utility model also proposes a toilet, including the above-mentioned drying and deodorizing module and a toilet body 20, wherein the deodorizing and drying module is disposed inside the toilet body 20.

[0037] Taking an axial flow fan as an example, the first fan 1 is located at the inlet end of the connecting duct 3. The axis of the inlet of the first fan 1 is parallel to the axis of the third outlet 2c of the second fan 2. Therefore, the axis of the outlet of the first fan 1 forms an angle with the axis of the first outlet 2a of the second fan 2. To reduce airflow resistance within the connecting duct 3, the connecting duct 3 is designed as an arc. For example, when the axis of the first outlet 2a is perpendicular to the axis of the third outlet 2c, the axis of the inlet of the connecting duct 3 is perpendicular to the axis of the outlet of the connecting duct 3.

[0038] refer to Figure 2 , Figure 5 and Figure 6 As shown, in order to guide the odor, the drying and deodorizing module also includes a deodorizing air duct 4, one end of which is connected to the air inlet of the first fan 1, and the other end is connected to the inner cavity of the toilet body 20.

[0039] To improve the deodorization effect, the drying and deodorizing module also includes a deodorizing component 6 for adsorbing or decomposing odors. To prevent odors from accumulating on the first fan 1 and being carried out during drying, the deodorizing component 6 is located on the air inlet side of the first fan 1. The deodorizing component 6 can employ any known deodorizing structure with deodorizing function, such as a physical adsorption deodorization structure with a built-in adsorption carrier (mainly activated carbon), a photocatalytic deodorization structure, a water-sealed assisted deodorization structure, etc., without specific limitations. Specifically, the deodorizing component 6 is located within the deodorizing air duct 4. Alternatively, the deodorizing component 6 can also be located on the air outlet side of the first fan 1.

[0040] Specifically, both the deodorizing air duct 4 and the connecting air duct 3 are injection molded parts. In order to reduce the processing steps, the deodorizing air duct 4 and the connecting air duct 3 are spaced apart and connected by a connecting part. The deodorizing air duct 4 and the connecting air duct 3 are integrally formed. The first fan 1 can be inserted into the gap between the deodorizing air duct 4 and the connecting air duct 3 and abut against the connecting part.

[0041] To ensure that the airflow reaches the area to be dried as much as possible, the drying and deodorizing module also includes a drying duct 5. One end of the drying duct 5 is connected to the third air outlet 2c of the second fan 2, and the other end is connected to the inner cavity of the toilet body 20. Specifically, in order to have a larger drying area, the effective flow area of ​​the end of the drying duct 5 connected to the inner cavity of the toilet body 20 gradually increases in the direction away from the second fan 2.

[0042] In some embodiments, the second fan 2 is disposed within the drying duct 5. The drying duct 5 is provided with a first duct opening for connecting to the connecting duct 3, a second duct opening for connecting to the outside atmosphere, and a third duct opening for connecting to the inner cavity of the toilet body 20. Specifically, to facilitate the installation of the second fan 2 within the drying duct 5, the drying duct 5 includes an upper housing 51 and a lower housing 52. The upper housing 51 and the lower housing 52 can be connected by means of bonding or bolting, not limited to bonding. During assembly, the second fan 2 can be assembled into the lower housing 51 first, and then the upper housing 51 and the lower housing 52 can be connected.

[0043] More specifically, the lower housing 52 and the deodorizing duct 4 are integrally injection molded to further reduce the processing difficulty of the drying and deodorizing module. Based on the arc-shaped setting of the connecting duct 3, the deodorizing duct 4 is approximately L-shaped to increase the turning radius of the connecting duct 3 and reduce the processing difficulty of the connecting duct 3.

[0044] In addition, refer to Figure 2 and Figure 7 As shown, the second fan 2 has a protrusion 21 on its fan housing, and the upper housing 51 has a limiting hole 5a for limiting the protrusion 21. The protrusion 21 is inserted into the limiting hole 5a to prevent the second fan 2 from rotating relative to the lower housing 52.

[0045] In some embodiments, a blocking element is also provided in the drying duct 5. The blocking element only allows airflow from the end of the drying duct 5 where the second fan 2 is located to the end of the drying duct 5 away from the second fan 2, so as to prevent unpurified odor from entering the second fan 2 through the drying duct 5 and causing the second fan 2 to be contaminated with odor.

[0046] In some embodiments, the blocking member includes a baffle 8 and a blocking part. The baffle 8 is hinged to the inner wall of the drying duct 5, and the blocking part is disposed on the side of the baffle 8 near the second fan 2. The blocking part restricts the baffle 8 from continuing to rotate in the direction of the second fan 2, and the baffle 8 can abut against the blocking part to disconnect the two ends of the drying duct 5.

[0047] Taking the upper end of the baffle 8 as hinged to the inner wall of the drying duct 5 as an example, the baffle 8 remains in contact with the blocking part under its own weight. When the second fan 2 is not started, the two ends of the drying duct 5 are disconnected, and the airflow cannot enter the second fan 2 from the end of the drying duct 5 that connects to the inner cavity. When the second fan 2 is started, under the push of the airflow, the baffle 8 rotates towards the end of the drying duct 5 that connects to the inner cavity, and the two ends of the drying duct 5 are connected, and the airflow flows out through the drying duct 5.

[0048] Specifically, the blocking part can be a blocking protrusion formed on the inner wall of the drying air duct 5, or the blocking part can be the fan housing of the second fan 2, and the baffle 8 can abut against the side wall of the fan housing of the second fan 2 to enclose the third air outlet 2c.

[0049] In other embodiments, in addition to the baffle 8 and the blocking part, the blocking member may also include an elastic member. The baffle 8 is connected to the elastic member and maintains a tendency to abut against the blocking part under the action of the elastic member. In this case, it is not limited to the upper end of the baffle 8 being hinged to the inner wall of the drying air duct 5, but the lower end of the baffle 8 may also be hinged to the inner wall of the drying air duct 5.

[0050] To improve the drying effect, the drying and deodorizing module also includes a heating element 7, which is located on the third air outlet 2c side of the second fan 2 to heat the airflow within the drying duct 5. The heating element 7 can be an electric heating wire heater or a PTC thermistor heater, etc., and is not specifically limited here. Based on the configuration of the drying duct 5, the heating element 7 is located within the drying duct 5.

[0051] 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 other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations 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.
