[0056] Figure 1 This diagram shows a partial structural schematic of the toilet provided in an embodiment of the present invention; Figure 2 This diagram illustrates the arrangement of the drying device and spray gun according to an embodiment of the present invention. (Refer to...) Figures 1-2 This embodiment provides a drying device and a toilet.

[0057] The toilet includes a toilet body, a bowl, and a spray gun 20. The bowl is formed within the toilet body, which has an installation space 10. The spray gun 20 is disposed within the installation space 10, and its nozzle 21 is retractable relative to the bowl to allow it to enter the bowl for personal washing or to retract for storage. The toilet also includes a drying device as described in this embodiment. This drying device is disposed within the installation space 10 and is arranged side-by-side with the spray gun 20. The drying device can supply air to the nozzle 21 of the spray gun 20, the installation space 10, or the bowl to perform different operating modes.

[0058] Figure 3 An exploded view of the drying apparatus provided in an embodiment of the present invention is shown; Figure 4 A cross-sectional view of the drying device provided in the embodiment of the present invention in drying operation mode is shown. Figure 5This diagram shows a partial exploded view of the drying device and spray gun provided in an embodiment of the present invention; Figure 6 This diagram shows a cross-sectional view of the drying device provided in the embodiment of the present invention in the spray gun sterilization working mode. Figure 1 ; Figure 7 This diagram shows a cross-sectional view of the drying device provided in the embodiment of the present invention in the spray gun sterilization working mode. Figure 2 . Reference Figures 3-7 The drying device includes a housing 100, a fan 200, and a heating mechanism 300.

[0059] Specifically, the outer casing 100 internally forms a first air duct 110 and a second air duct 120. The drying air outlet 111 of the first air duct 110 is connected to the toilet bowl. The second air duct 120 is provided with an installation space air outlet 121 and a spray gun air outlet. The installation space air outlet 121 is selectively connected to the installation space 10, and the spray gun air outlet faces the spray gun 20 of the toilet. The first air duct 110 and the second air duct 120 are selectively connected, such as... Figure 4 and Figure 6 As shown. The airflow in the second air duct 120 can be used for disinfection by the spray gun 20 and drying within the installation space 10. The airflow exiting through the drying outlet 111 can be used for drying human bodies or disinfecting toilets. The fan 200 is connected to the housing 100 and to the first air duct 110, providing airflow. The heating mechanism 300 is disposed in the first air duct 110, heating the airflow, and the temperature of the heating mechanism 300 is adjustable to adapt to different working conditions.

[0060] More specifically, the first air duct 110 is provided with a first windbreak structure 130, which has a first position that disconnects the first air duct 110 and the second air duct 120, such as... Figure 4 As shown; the first windbreak structure 130 also has a second position that connects the first air duct 110 and the second air duct 120 and blocks the air outlet of the drying air outlet 111, as shown. Figure 6 As shown. It should be noted that in other embodiments, when the first windbreak structure 130 is in the second position, it may not block the drying air outlet 111. In this embodiment, the first windbreak structure 130 is movably disposed in the first air duct 110 and can rotate between the first position and the second position.

[0061] More specifically, the drying device also includes a drive mechanism 400. The drive mechanism 400 is disposed at the rotatable connection of the first windbreak structure 130, which can switch between the first position and the second position under the drive of the drive mechanism 400. In this embodiment, the drive mechanism 400 is specifically a motor, disposed outside the housing 100, with its output end extending into the first air duct 110 and connected to the first windbreak structure 130 to drive its rotation.

[0062] Continue to refer to Figure 2 , Figure 3 and Figure 5 The housing 100 includes a bottom cover 160 and a top cover 170. The top cover 170 is detachably connected to the bottom cover 160 by means of snaps or the like. The bottom cover 160 and the top cover 170 enclose the first air duct 110 and the second air duct 120. The second air duct 120 is specifically formed in the top cover 170, and the air outlet 121 of the mounting space is also located on the top of the top cover 170. This arrangement facilitates the separation of the housing 100 to allow for the inspection or replacement of its internal components.

[0063] Continue to refer to Figure 2 , Figure 5 and Figure 7 The drying device also includes a rotating hood 510, which is connected to the upper cover 170. The internal space of the rotating hood 510 and the internal space of the upper cover 170 together form the second air duct 120. The outlet of the rotating hood 510 is the spray gun outlet, which is set at a right angle to the drying outlet 111 to match the side-by-side arrangement of the spray gun 20 and the drying device, so that the airflow of the drying device can reach the spray gun 20.

[0064] Specifically, the drying device also includes a spray gun air guide shroud 520. The spray gun 20 also includes a spray gun self-cleaning shroud 22. When the spray gun 20 is in a non-working state or a self-cleaning state, the nozzle 21 retracts into the spray gun self-cleaning shroud 22. The spray gun air guide shroud 520 is disposed on the spray gun self-cleaning shroud 22 and is vertically positioned directly opposite the nozzle 21, and is connected to the air deflector shroud 510 via a connecting pipe 530. Through the above arrangement, the airflow in the air deflector shroud 510 can be vertically guided to the nozzle 21, thereby increasing the contact area between the airflow and the nozzle 21 and improving the disinfection effect and efficiency of the nozzle 21.

[0065] To be more specific, refer to Figures 3-6 The drying device also includes a temperature sensor 600. The temperature sensor 600 is disposed within the housing 100 and can detect the temperature of the airflow within the housing 100. In this embodiment, the temperature sensor 600 is specifically disposed within the air hood 510, near the spray gun outlet, enabling it to more accurately reflect the temperature of the airflow at that location.

[0066] It should be noted that a temperature sensing component (not shown) can also be installed in the first air duct 110. This temperature sensing component is specifically located near the drying air outlet 111 and can detect the temperature of the airflow flowing into the toilet bowl through the drying air outlet 111.

[0067] More specifically, the toilet also includes a control module. The heating mechanism 300, the drive mechanism 400, the temperature sensor 600, and other temperature sensing components are all communicatively connected to the control module. The control module can control the heating temperature of the heating mechanism 300 based on the current operating mode of the drying device and the temperatures detected by the temperature sensor 600 and the temperature sensing module. The control module can also control the operation of the drive mechanism 400 based on the current operating mode of the drying device, so that the first baffle structure 130 is in a first position or a second position. The user can set the operating mode of the drying device through the control module, or the control module can automatically select the operating mode of the drying device. In this embodiment, the control module can specifically be a PLC controller or a microcontroller, which are existing technologies, and their structure and control principles will not be described in detail here.

[0068] Figure 8 This is a cross-sectional view showing the drying device provided in an embodiment of the present invention in its moisture-proof operating mode within the installation space. (Refer to...) Figures 1-8 The upper cover 170 is provided with a second windbreak structure 140, which is rotatably disposed at the air outlet 121 of the installation space, and can open or close the air outlet 121. The air volume of the fan 200 is adjustable, and the fan 200 has a driving air volume. The second windbreak structure 140 can open the air outlet 121 of the installation space under the push of the airflow of the driving air volume. It should be noted that when the drying device sterilizes the spray gun 20, the fan 200 can output air at the spray gun sterilization air volume, which is less than the driving air volume. In this embodiment, the fan 200 is also communicatively connected to the above-mentioned control module, which can control the air volume of the fan 200.

[0069] Preferably, a sealing element 150 is provided around the air outlet 121 of the installation space, and the sealing element 150 can abut against the second windbreak structure 140. Specifically, the sealing element 150 can be a rubber ring, which can ensure the sealing performance between the two when the second windbreak structure 140 covers the air outlet 121 of the installation space.

[0070] Preferably, the drying device further includes an auxiliary disinfection mechanism 700, which is connected to the first air duct 110 and / or the second air duct 120. The auxiliary disinfection mechanism 700 is configured to generate a disinfecting substance. In this embodiment, the auxiliary disinfection mechanism 700 is disposed outside the outer casing 100 and connected to the interior of the outer casing 100, specifically connected to the common portion of the first air duct 110 and the second air duct 120, i.e., connected upstream of the heating mechanism 300. When the first air duct 110 and the second air duct 120 are connected, the disinfecting substance generated by the auxiliary disinfection mechanism 700 can enter the second air duct 120.

[0071] Alternatively, in other embodiments, the auxiliary disinfection mechanism 700 may also be disposed inside the housing 100, specifically upstream of the heating mechanism 300.

[0072] Specifically, the auxiliary disinfection mechanism 700 can be a negative ion generator, a plasma generator, or an ozone generator, etc., and the disinfection substances it produces can be negative ions, plasma, or ozone, etc. Through the aforementioned auxiliary disinfection mechanism 700, the disinfection effect and efficiency of the drying device during the disinfection process can be improved.

[0073] The drying device provided in this embodiment has multiple working modes, namely, human buttock drying mode, spray gun disinfection mode, and installation space ventilation drying mode.

[0074] In the human buttocks drying mode, the control module controls the drive mechanism 400 to rotate and maintain the first air baffle structure 130 in the first position, and controls the fan 200 to turn on. The user can then use a remote control to set the temperature of the heating mechanism 300 or adjust the fan speed of the fan 200. At this time, airflow is blown from the drying outlet 111 into the toilet bowl to dry the human buttocks. Figure 4 As shown.

[0075] The spray gun disinfection modes include automatic disinfection mode and manual disinfection mode.

[0076] In automatic disinfection mode, when the user leaves the toilet seat, the control module can drive the drive mechanism 400 to rotate the first baffle structure 130 to the second position, and keep the first baffle structure 130 in the second position for a preset time. Figure 6As shown. The control module can control the heating mechanism 300 to raise the temperature and uses the temperature sensor 600 to monitor the airflow temperature, achieving closed-loop control of the disinfection airflow temperature to keep it within the high-efficiency sterilization air temperature range. If the temperature of the disinfection airflow cannot reach the sterilization air temperature range, the control module reports an error and stops working. Once the temperature of the disinfection airflow reaches the sterilization air temperature range, the high-temperature sterilization process of the spray gun 20 begins. At this time, the airflow in the drying device can sequentially pass through the first air duct 110, the second air duct 120, the connecting pipe 530, and the spray gun air guide shroud 520, finally guiding to the nozzle 21 to achieve sterilization, as shown. Figure 6 and Figure 7 As shown.

[0077] After the high-temperature disinfection process of the spray gun 20 reaches the preset disinfection time, the heating mechanism 300 stops running, and the fan 200 delays its operation for a period of time to eliminate the residual heat of the heating mechanism 300. At the same time, the control drive mechanism 400 is activated to drive the first windbreak structure 130 to rotate back to the first position.

[0078] In manual disinfection mode, users can manually turn on the spray gun using a remote control or other means to perform the same steps as in automatic disinfection mode. It should be noted that in manual disinfection mode, users can set the preset disinfection duration or specify a set number of uses before the toilet is disinfected.

[0079] It should be noted that in both automatic and manual disinfection modes, the auxiliary disinfection mechanism 700 will operate simultaneously to enhance the disinfection effect.

[0080] Alternatively, in the spray gun disinfection mode, the fan 200 can be de-energized, and the auxiliary disinfection mechanism 700 can work independently. When the production of disinfection substances such as negative ions is sufficient, they will be released onto the surface of the nozzle 21 to continuously disinfect the spray gun 20.

[0081] It should be noted that the ventilation and drying mode in this embodiment is specifically achieved by increasing the airflow of the fan 200 based on the spray gun disinfection mode. In the ventilation and drying mode, when the user leaves the toilet seat, the control module can drive the drive mechanism 400 to rotate the first baffle structure 130 to the second position, and maintain the first baffle structure 130 in the second position for a preset time. The control module can also control the heating mechanism 300 to heat up and use the temperature sensor 600 to monitor the airflow temperature, achieving closed-loop control of the disinfection airflow temperature to keep it within the sterilization temperature range. If the temperature of the disinfection airflow cannot reach the sterilization temperature range, the control module reports an error and stops working. When the airflow of the disinfection airflow reaches the spray gun's disinfection airflow and the temperature reaches the sterilization temperature range, the high-temperature disinfection process of the spray gun 20 begins. Simultaneously, the airflow of the fan 200 is increased to the driving airflow. At this time, the second baffle structure 140 can open the air outlet 121 of the installation space under the airflow of this driving airflow, allowing airflow to enter the air outlet 121 of the installation space, thereby achieving drying, moisture prevention, and disinfection inside the air outlet 121 of the installation space. Figure 1 and Figure 8 As shown. After the high-temperature disinfection process of the spray gun 20 has reached the preset disinfection time, the heating mechanism 300 stops operating, and the fan 200 delays its operation for a period of time to eliminate the residual heat of the heating mechanism 300. At the same time, the control drive mechanism 400 is activated to rotate the first windbreak structure 130 back to the first position. At this time, due to the reduced airflow of the fan 200, the second windbreak structure 140 can re-seal the air outlet 121 of the installation space under the action of gravity. It should be noted that, in order to ensure that the second windbreak structure 140 can respond to the action in a timely manner under the action of gravity, in this embodiment, the second windbreak structure 140 is provided with a counterweight.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
