Description

Technical Field

[0001] This invention relates to the field of intelligent toilet technology, and more particularly to a toilet heating assembly and toilet device. Background Technology

[0002] With technological advancements, the heating components of smart toilets are gradually moving towards miniaturization, modular integration, and increased airflow. However, these changes have led to inconsistent air temperature within the duct, meaning that the temperature varies at different points in the duct. For example, the temperature in the center is generally lower than the surrounding air. If the temperature sensor cannot accurately reflect the overall or average air temperature in the duct, the controller may not be able to adjust the heater power in a timely manner, ultimately resulting in unstable airflow temperature throughout the unit and negatively impacting the user experience.

[0003] 1. Due to the miniaturized design, the air temperature sensor needs to be placed closer to the electric heating wire during the air duct design. There is not enough space for the warm air to be mixed evenly, and the air temperature varies at multiple points in the air duct (2), resulting in poor air temperature consistency in the air duct.

[0004] 2. Modular integration, for example, placing the SCR-controlled PCBA assembly in the air duct and using the cool air from the fan for heat dissipation. However, the components and wiring harnesses on the SCR-controlled PCBA will cause uncertainty in the direction of the airflow, resulting in poor temperature uniformity in the air duct.

[0005] 3. High air volume is the guarantee of fast drying, but high air volume requires high power of heating wire to ensure the air temperature at the outlet. High power will result in poor air temperature consistency in the air duct.

[0006] In existing technologies, cylindrical air temperature sensors are used, and multiple air temperature sensors are installed inside the air duct for multi-point monitoring to reflect the air temperature in the air duct. However, this method has the following drawbacks:

[0007] First: Using multiple wind and temperature sensors increases the product cost and also makes installation more difficult.

[0008] Second: Multiple air temperature sensors are located around the periphery of the air duct, lacking monitoring of the middle section of the air duct cross-section. The monitoring range is limited and cannot accurately reflect the overall or average air temperature in the air duct. Summary of the Invention

[0009] The purpose of this invention is to overcome the shortcomings of the prior art and provide a novel toilet heating air assembly and toilet device. By using a metal heat-conducting element and a temperature sensor, it reduces product cost and installation difficulty, and can obtain more accurate air duct temperature, which is conducive to timely adjustment of heater power, making the overall air outlet temperature more stable and improving the user experience.

[0020] The slot and the temperature sensor are located in the air duct.

[0024] In one of the alternative technical solutions, one end of the fixing sleeve is connected to a limiting sleeve, the limiting sleeve is inserted into the fixing sleeve, and one end of the temperature sensor with a wire harness is located in the limiting sleeve;

[0025] The limiting sleeve has a notch extending along the axial direction, through which the wire harness passes.

[0026] In one of the alternative technical solutions, a limiting block is provided on one side of the limiting sleeve on the outer surface of the air duct;

[0050] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0051] like Figure 1-4 and Figure 8-9 As shown, a toilet warm air assembly provided in one embodiment of the present invention includes a fan 1, an air duct 2 connected to the fan 1, a heater 3 assembled in the air duct 2, a controller 4 for controlling the heater 3, and an air temperature monitoring module 5 for monitoring the air temperature.

[0052] The wind temperature monitoring module 5 includes a metal heat-conducting element 51 and a temperature sensor 52.

[0053] The metal heat-conducting element 51 includes a connecting heat-conducting part 511 connected to the temperature sensor 52 and a porous heat-conducting part 512 connected to the connecting heat-conducting part 511. The partition 5122 between any two adjacent ventilation holes 5121 of the porous heat-conducting part 512 constitutes a wind temperature collection part.

[0054] The porous heat-conducting part 512 is assembled in the air duct 2 and is located between the air outlet of the heater 3 and the air outlet of the air duct 2.

[0055] The heater 3 and the temperature sensor 52 are respectively connected to the controller 4. The controller 4 adjusts the power of the heater 3 according to the real-time air temperature monitored by the temperature sensor 52.

[0056] The toilet warm air assembly provided by this invention is a blower assembly for a smart toilet.

[0057] The toilet heating system includes a fan 1, an air duct 2, a heater 3, a controller 4, and a temperature monitoring module 5.

[0058] Duct 2 is connected to fan 1, which blows air into duct 2. Heater 3 can be a resistance wire heater or other types of heater. Heater 3 is installed in duct 2, downstream of fan 1. In this invention, upstream and downstream are defined along the airflow direction in duct 2. Controller 4 can be a microcontroller unit (MCU), a silicon controlled rectifier (SCR) board, etc. Heater 3 and controller 4 are connected by wires for signal transmission. Controller 4 can control the power of heater 3 and adjust its power to regulate the air temperature. Generally, the outlet air temperature of the toilet's warm air assembly is preferably within a certain range. If the outlet air temperature is detected to be too high, controller 4 reduces the power of heater 3 to lower the air temperature in duct 2. If the outlet air temperature is detected to be too low, controller 4 increases the power of heater 3 to raise the air temperature in duct 2. The control of heater 3's power by controller 4 is prior art and will not be described further here.

[0059] If needed, the fan 1 can also be connected to the controller 4 via a wire, and the controller 4 can control the switching on and off of the fan 1. Of course, the fan 1 can also be connected to other controllers or mainboards of the toilet for automatic control of the switch.

[0060] Depending on the requirements, the controller 4 can be integrated with the air duct 2 or optionally with the fan 1.

[0061] The air temperature monitoring module 5 is used to monitor the air temperature in the air duct 2 in real time, so that the controller 4 can determine the current air temperature in the air duct 2 and thus determine whether to adjust the current power of the heater 3.

[0062] Specifically, the air temperature monitoring module 5 includes a metal heat-conducting element 51 and a temperature sensor 52. The metal heat-conducting element 51 is made of a metal with good thermal conductivity, which can collect heat from the air duct 2 at multiple points and send it to the temperature sensor 52. The metal is preferably a copper alloy, stainless steel, etc.

[0063] Preferably, the metal heat-conducting element 51 is a metal heat-conducting plate or a metal heat-conducting sheet, with a thickness as thin as possible, preferably less than 2 mm, in order to reduce thermal inertia and improve the sensitivity of wind temperature sensing.

[0064] The metal heat-conducting element 51 adopts the following design:

[0065] The metal heat-conducting element 51 includes a connecting heat-conducting part 511 and a porous heat-conducting part 512. The porous heat-conducting part 512 is connected to the connecting heat-conducting part 511, and the two can be integrally formed. The connecting heat-conducting part 511 is used to mount the temperature sensor 52, and the porous heat-conducting part 512 is used to place the air duct 2 for heat detection or collection. The porous heat-conducting part 512 has a plurality of spaced ventilation holes 5121, and the partition 5122 between any two adjacent ventilation holes 5121 constitutes an air temperature collection part. The porous heat-conducting part 512 has multiple air temperature collection parts.

[0066] During installation, the temperature sensor 52 can be optionally mounted inside the air duct 2, but is preferably mounted outside the air duct 2 to avoid obstructing the wind. The temperature sensor 52 is connected to the controller 4 via a wire to achieve signal transmission.

[0067] A porous heat-conducting part 512 is assembled in the air duct 2, located downstream of the air outlet of the heater 3 and upstream of the air outlet of the air duct 2. The porous heat-conducting part 512 is arranged along the longitudinal section of the air duct 2, where the longitudinal section refers to the section perpendicular to the extension direction of the air duct 2. The porous heat-conducting part 512 can simultaneously collect heat from multiple points in the air duct 2. Due to the good heat transfer effect and high heat transfer efficiency of the metal heat-conducting element 51, the heat collected by multiple air temperature collection parts (ribs 5122) is transferred to the connecting heat-conducting part 511 almost simultaneously. The heat collected by the connecting heat-conducting part 511 is essentially the average heat from multiple air temperature collection parts. This collected heat is then transferred to the temperature sensor 52, and the air temperature monitored by the temperature sensor 52 is the overall or average air temperature of the air duct 2. The temperature sensor 52 transmits a real-time temperature signal or a current temperature signal to the controller 4, which adjusts the power of the heater 3 based on the real-time or current temperature signal. Specifically, assuming the preset outlet air temperature range of the toilet's warm air assembly is between T1 and T2. If the current or real-time air temperature detected by temperature sensor 52 is lower than T1, controller 4 increases the power of heater 3 to raise the air temperature in duct 2. When the current or real-time air temperature detected by temperature sensor 52 is between T1 and T2, the current power of heater 3 is maintained. If the current or real-time air temperature detected by temperature sensor 52 is higher than T2, controller 4 decreases the power of heater 3 to lower the air temperature in duct 2. When the current or real-time air temperature detected by temperature sensor 52 is between T1 and T2, the current power of heater 3 is maintained.

[0068] In summary, compared with the existing technology that uses multiple air temperature sensors, the toilet warm air assembly provided by the present invention uses a metal heat-conducting element 51 and a temperature sensor 52 in its air temperature monitoring module 5, which saves the number of temperature sensors 52, helps to reduce product cost, and is also convenient for installation.

[0069] The toilet warm air assembly provided by this invention features a porous heat-conducting portion 512 of the metal heat-conducting element 51 covering the cross-section of the air duct 2, thus achieving a more accurate air duct temperature. The air temperature transmitted from the metal heat-conducting element 51 to the temperature sensor 52 is the overall or average air temperature aggregated from multiple points, eliminating the need for the controller to first calculate the average value of multiple temperature sensors and then adjust the heater power, which can lead to power adjustment lag, as is required in existing technologies. The control method of the toilet warm air assembly provided by this invention is simpler and more convenient, facilitating timely adjustment of the heater 3's power and resulting in a more stable overall air outlet temperature, thus improving the user experience.

[0070] In one embodiment, the periphery of the porous heat-conducting portion 512 can be connected to the inner surface of the air duct 2, thereby covering the entire longitudinal section of the air duct 2. The periphery, middle, and areas between the periphery and middle of the longitudinal section of the air duct 2 all have air temperature collection portions, resulting in better air temperature collection.

[0071] In one embodiment, the periphery of the porous heat-conducting part 512 is sealed to the air duct 2 to prevent air leakage between the periphery of the porous heat-conducting part 512 and the inner wall of the air duct 2, thereby avoiding affecting the accuracy of the monitoring results.

[0072] A sealing ring can be installed between the periphery of the porous heat-conducting part 512 and the air duct 2, or the periphery of the porous heat-conducting part 512 can be bonded to the inner wall of the air duct 2 with sealant.

[0073] In one embodiment, such as Figure 3 and Figure 5 As shown, the air duct 2 has a slot 23, and the edge of the porous heat-conducting part 512 is engaged in the slot 23.

[0074] In this embodiment, a ring-shaped groove can be opened on the inner wall of the air duct 2 to engage the edge of the porous heat-conducting part 512 in the groove 23. This not only improves the installation stability of the porous heat-conducting part 512, but also helps to improve the sealing between the periphery of the porous heat-conducting part 512 and the inner wall of the air duct 2.

[0075] In one embodiment, such as Figure 3 and Figure 8-9 As shown, the porous heat-conducting part 512 is in the shape of a grid, with multiple rectangular ventilation holes 5121 and multiple baffles 5122. Under the condition of not affecting the air outlet of the air duct 2 as much as possible, more air temperature collection parts are arranged, which is conducive to improving the accuracy of air temperature monitoring of the air duct.

[0076] In one embodiment, such as Figure 8-9 As shown, the heat-conducting part 511 has a sleeve part 5111 or a slot part 5113, and the temperature sensor 52 is inserted into the sleeve part 5111 or the slot part 5113.

[0077] In this embodiment, the heat-conducting part 511 has a sleeve part 5111, or the heat-conducting part 511 has a slot part 5113, and the central angle of the cross section of the slot part 5113 is preferably greater than 180°.

[0078] When the heat-conducting part 511 has a sleeve part 5111, the detection end of the temperature sensor 52 is inserted into the sleeve part 5111, which provides good assembly stability and enables timely reception of the heat transmitted from the sleeve part 5111 for temperature monitoring.

[0079] When the heat-conducting part 511 has a slot 5113, the detection end of the temperature sensor 52 is inserted into the slot 5113, which facilitates assembly. Whether it is installed in place can be observed through the side slot of the slot 5113. The total heat of the heat-conducting part 511 can be transferred to the temperature sensor 52 through the slot wall of the slot 5113.

[0080] In one embodiment, such as Figure 9 As shown, the metal heat-conducting element 51 includes two porous heat-conducting parts 512 and a slot part 5113, with the two porous heat-conducting parts 512 connected to opposite sides of the slot part 5113.

[0081] The slot 5113 and the temperature sensor 52 are located in the air duct 2.

[0082] In this embodiment, the metal heat-conducting element 51 includes two porous heat-conducting parts 512, and the connecting heat-conducting part 511 includes a slot part 5113.

[0083] The slot portion 5113 is located between two porous heat-conducting portions 512, which are connected to opposite sides of the slot portion 5113. The temperature sensor 52 is inserted into the slot portion 5113.

[0084] The assembly method of the metal heat-conducting element 51 and temperature sensor 52 provided in this embodiment can meet the arrangement requirements of a single air duct with a slightly larger width. During assembly, the slot part 5113 and the temperature sensor 52 are roughly located in the middle of the air duct 2, and the two porous heat-conducting parts 512 are located on the left and right sides for temperature collection.

[0085] The assembly method of the metal heat-conducting element 51 and temperature sensor 52 provided in this embodiment can also meet the arrangement requirements of the air duct adopting a left and right double branch air duct. During assembly, a porous heat-conducting part 512 is located in one branch air duct, and the slot part 5113 and temperature sensor 52 are approximately located in the partition between the two branch air ducts.

[0086] In one embodiment, such as Figure 2-4 , Figure 6 and Figure 8 As shown, the metal heat-conducting element 51 includes a porous heat-conducting part 512 and a sleeve part 5111. The sleeve part 5111 is connected to one end of the porous heat-conducting part 512 through a heat-conducting connecting piece 5112.

[0087] The outer side of the air duct 2 has a fixing sleeve 24, and there is a channel 25 between the air duct 2 and the fixing sleeve 24.

[0088] The heat-conducting connecting piece 5112 passes through the channel 25, and the sleeve part 5111 is inserted into the fixed sleeve 24.

[0089] In this embodiment, the metal heat-conducting element 51 includes a porous heat-conducting portion 512, and the connecting heat-conducting portion 511 includes a sleeve portion 5111 and a heat-conducting connecting piece 5112. The sleeve portion 5111 is connected between the porous heat-conducting portion 512 and the sleeve portion 5111 through the heat-conducting connecting piece 5112. The sleeve portion 5111 extends outward from one end of the porous heat-conducting portion 512, thereby allowing the temperature sensor 52 to be arranged outside the air duct 2.

[0090] The outer surface of the air duct 2 has a fixing sleeve 24, specifically, the fixing sleeve 24 is installed on the top surface of the air duct 2. A channel 25 is provided between the air duct 2 and the fixing sleeve 24 for the passage of the heat-conducting connecting piece 5112. During assembly, the sensing end of the temperature sensor 52 is inserted into the sleeve portion 5111, the heat-conducting connecting piece 5112 passes through the channel 25, and the two are sealed together by a sealing ring or sealant to prevent air leakage. Finally, the sleeve portion 5111 is fixed in the fixing sleeve 24, thereby fixing the temperature sensor 52 to the outside of the air duct 2.

[0091] In one embodiment, such as Figure 3-4 and Figure 6-7 As shown, one end of the fixed sleeve 24 is connected to the limiting sleeve 26, the limiting sleeve 26 is inserted into the fixed sleeve 24, and one end of the wire harness 53 of the temperature sensor 52 is in the limiting sleeve 26.

[0092] The limiting sleeve 26 has a notch 261 extending along the axial direction, through which the wire harness 53 passes.

[0093] In this embodiment, to limit and fix the end of the wire harness 53 (wire) of the temperature sensor 52, a limiting sleeve 26 is connected to the open end of the fixing sleeve 24. The limiting sleeve 26 and the fixing sleeve 24 are detachably connected, for example, by plugging or snapping. The limiting sleeve 26 has a notch 261 that extends axially along the limiting sleeve 26 and is used for the wire harness 53 to pass through for connection.

[0094] During assembly, after the sleeve portion 5111 is fixed in the fixing sleeve 24, the end of the wire harness 53 (wire) of the temperature sensor 52 extends out of the outside of the fixing sleeve 24. Then, the wire harness 53 is passed through the notch 261, and the end of the temperature sensor 52 is inserted into the limiting sleeve 26. Finally, the limiting sleeve 26 is connected to the fixing sleeve 24 to limit and fix the temperature sensor 52, and also to provide protection.

[0095] In one embodiment, such as Figure 6-7 As shown, a limiting block 27 is located on one side of the limiting sleeve 26 on the outer surface of the air duct 2. A limiting claw 262 is connected to the limiting sleeve 26, and the limiting claw 262 engages with the limiting block 27.

[0096] In this embodiment, a limiting claw 262 is connected to the side of the limiting sleeve 26 opposite to the notch 261. The limiting claw 262 extends toward the fixing sleeve 24, and its outer surface has a protrusion. A limiting block 27 is also specially configured on the outer surface of the air duct 2, located on one side of the fixing sleeve 24. During assembly, after the limiting sleeve 26 and the fixing sleeve 24 are assembled, the limiting claw 262 is engaged with the limiting block 27 to improve the installation stability of the limiting sleeve 26.

[0097] In one embodiment, such as Figure 2 and Figure 4-6 As shown, the air duct 2 includes a lower housing 21 and an upper housing 22, which are detachably connected to the lower housing 21.

[0098] In this embodiment, the air duct 2 consists of a lower housing 21 and an upper housing 22. The two can be detachably connected by means of snap-fit ​​or pin connection, so as to install the fan 1, heater 3, controller 4 and air temperature monitoring module 5.

[0099] In one embodiment, such as Figure 5-6 As shown, a housing buckle 28 is provided on the upper housing 22 / lower housing 21, and correspondingly, a housing block 29 is provided on the lower housing 21 / upper housing 22. The housing buckle 28 and the housing block 29 are engaged.

[0100] In this embodiment, the lower housing 21 and the upper housing 22 are connected by a snap-fit ​​mechanism. Optionally, a housing latch 28 can be provided on the upper housing 22, and a housing latch 29 can be provided on the lower housing 21, with the housing latch 28 and housing latch 29 snapped together. Alternatively, a housing latch 28 can be provided on the lower housing 21, and a housing latch 29 can be provided on the upper housing 22, with the housing latch 28 and housing latch 29 snapped together.

[0101] In one embodiment, such as Figure 2 and Figure 4-6 As shown, the lower housing 21 includes a tray portion 211 and a main body portion 212 connected to the tray portion 211. The fan 1 is detachably mounted on the tray portion 211. The upper housing 22 is detachably connected to the main body portion 212.

[0102] In this embodiment, the lower housing 21 includes a tray portion 211 and a main body portion 212. The tray portion 211 is used to mount the fan 1, and the main body portion 212 is the lower half forming the air duct 2. The main body portion 212 is generally U-shaped. One end of the main body portion 212 is connected to the tray portion 211, and the two can be integrally formed. The fan 1 is directly mounted on the tray portion 211, and the two can be connected by clips, pins, etc. The upper housing 22 is also generally U-shaped and is connected to the main body portion 212. One end of the upper housing 22 is connected to the air outlet of the fan 1. The upper housing 22 does not cover the top of the fan 1 so that the air inlet of the fan 1 can be located at the top.

[0103] In one embodiment, such as Figure 1 and 5 As shown, the tray section 211 is provided with a tray claw 2111, which engages with the fan 1.

[0104] In this embodiment, two or more tray claws 2111 are arranged at intervals along the circumferential direction on the tray part 211. During assembly, the tray claws 2111 are clamped to the top surface of the fan 1 to fix the fan 1 on the tray part 211, which facilitates the assembly and disassembly of the fan 1.

[0105] In one embodiment, such as Figure 2 and Figure 5 As shown, a mounting groove 2121 is provided on the main body 212, and the controller 4 is installed in the mounting groove 2121. Integrating the controller 4 on the main body 212 of the lower housing 21 of the air duct 2 can shorten the distance between the controller 4 and the heater 3, which facilitates wiring and installation.

[0106] In one embodiment, such as Figure 1-2 and Figure 6 As shown, a shielding cover 221 is installed at the end of the upper housing 22. The shielding cover 221 extends upward at an angle and serves to guide the diffusion of the air coming out of the air outlet of the air duct 2, and also serves to shield and prevent objects above from falling into the air outlet of the air duct 2.

[0110] The above are merely the principles and preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several other modifications can be made based on the principles of the present invention, and these modifications should also be considered within the scope of protection of the present invention.
