Description

Technical Field

[0001] This invention relates to the field of vehicle technology, specifically to a dehumidifying automotive floor heating system, control method, and vehicle. Background Technology

[0002] With the increasing demand for automotive comfort, underfloor heating systems have gradually become a common feature in mid-to-high-end models and vehicles used in cold northern regions. Existing automotive underfloor heating systems are mainly divided into water-based systems for gasoline vehicles (relying on waste heat from the engine coolant) and electric-heated systems for new energy vehicles (such as PTC heating films and heat pump-driven systems). Their core operating logic is to heat the area under the car carpet using heating elements to keep the feet and lower limbs of passengers warm.

[0003] However, existing automotive underfloor heating systems still suffer from various core technological shortcomings in real-world winter weather conditions, particularly during rain and snow. For example, the problem of damp carpets remains unresolved: during rain and snow, passengers' shoes bring in large amounts of rainwater and snowmelt, which seeps into the surface and interior of the car carpet. Current underfloor heating systems only provide heating and lack an active dehumidification mechanism. The heat cannot quickly evaporate the moisture inside the carpet; instead, the localized high temperature and humidity accelerate moisture retention, causing the carpet to remain damp for extended periods. The heating efficiency is also affected: damp carpets have lower heat transfer efficiency than dry carpets, increasing the heating load on the system and leading to higher energy consumption. Furthermore, the damp environment may cause a decrease in the insulation performance of the heating components, posing a short-circuit risk.

[0004] In summary, existing automotive floor heating systems generally suffer from the functional defect of "only heating and not dehumidifying," making them unsuitable for use in winter rainy and snowy weather scenarios. This results in compromises in comfort, safety, and health. Therefore, how to solve the technical problems existing in the current technology is a direction that the industry urgently needs to research. Summary of the Invention

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] It should be noted that although functional modules are divided in the system diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the system or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0021] Before providing a detailed description of the embodiments of this application, some of the nouns and terms involved in the embodiments of this application will be explained first. The nouns and terms involved in the embodiments of this application are subject to the following interpretations.

[0022] The carpet surface refers to the carpet installed inside the car, which is mainly used to decorate the floor of the car cabin, improve the feel underfoot, reduce noise, absorb moisture, and keep warm.

[0023] A water collection box is a box used to collect water. It is usually connected to the vehicle's drainage system so that the collected water can be drained out of the vehicle.

[0024] In vehicle-related technologies, how to solve the various problems caused by damp carpets (water accumulation) in existing technologies? Those skilled in the art generally believe that the main function of automotive floor heating is heating, and dehumidification can be achieved solely through the air conditioning system. However, excessively damp carpets increase the dehumidification burden on the air conditioning system, causing various problems (such as discomfort). Therefore, this application discloses a dehumidifying automotive floor heating system, a corresponding control method, and a vehicle.

[0025] Please refer to the following: Figure 1 and Figure 4 , Figure 1 This is a schematic diagram showing the relationship between the various components of a dehumidifying car floor heating system. Figure 4 This is a flowchart of the dehumidification control method.

[0026] This application discloses a dehumidifying car floor heating system. The specific components of the dehumidifying car floor heating system include: a carpet surface layer 101, a water collection box, a hydrophobic composite system, a dehumidification system, a floor heating layer 301, and a collaborative control system.

[0027] The hydrophobic composite system is used to collect water droplets on the carpet surface 101 and transfer them to a water collection box. The underfloor heating layer 301 is used to generate heat and transfer it to the carpet surface 101. The dehumidification system is used to absorb moisture from the carpet surface 101 or the air. The coordinated control system is used to coordinate the control of the underfloor heating layer 301 or the dehumidification system to reduce the amount of moisture returning to the carpet surface 101.

[0028] In practical applications, during rainy or snowy weather in winter, rainwater and snowmelt brought into the vehicle by passengers seep into the carpet surface 101. The hydrophobic composite system collects water droplets from the carpet surface 101 through contact with it. To ensure these water droplets are promptly removed, the hydrophobic composite system connects to a water collection box and transfers the collected water droplets to the box.

[0029] For the structure of hydrophobic composite systems, refer to Figure 2 , Figure 2 This is a schematic diagram illustrating the connection relationship between the hydrophobic composite system and other components in one embodiment. In one embodiment, the hydrophobic composite system includes: a micro / nano hydrophobic coating 201 and a water-guiding channel 202.

[0030] The water-guiding channel 202 is disposed along the edge of the carpet surface layer 101, and the micro-nano hydrophobic coating 201 is disposed on the lower side of the carpet surface layer 101. The micro-nano hydrophobic coating 201 is used to repel water droplets that come into contact with it towards the edge of the carpet surface layer 101. The water-guiding channel 202 is connected to the water collection box, and the water-guiding channel 202 is used to collect water droplets that are repelled from the edge of the carpet surface layer 101 and transfer them to the water collection box.

[0031] In this embodiment, since the micro / nano hydrophobic coating 201 is located on the lower side of the carpet surface 101, water in the carpet surface 101 will move into the micro / nano hydrophobic coating 201 due to gravity. Due to the properties of the micro / nano hydrophobic coating 201, it utilizes its superhydrophobic surface to rapidly form water droplets. These droplets will flow along the gaps in the raised array on the surface of the micro / nano hydrophobic coating 201 towards the water guide grooves 202 at the edge.

[0032] The water channel 202 is designed with a certain slope. After the water droplets collect, they flow into the water collection box through the slope of the water channel 202. This completes the collection of water droplets. It prevents water from accumulating on the carpet surface 101, reduces the humidity on the carpet surface 101, and reduces the overall humidity in the vehicle cabin by reducing the humidity on the carpet surface 101.

[0033] Of course, in addition to the hydrophobic composite system to remove liquid water from the carpet surface 101, further and reliably reducing the humidity inside the vehicle cabin requires the absorption of water vapor from the air. That is, absorbing moisture from the carpet surface 101 or the air (the air inside the vehicle cabin). Therefore, this application also includes a dehumidification system.

[0034] In one embodiment, the dehumidification system includes a semiconductor condenser, heat-conducting fins, and an exhaust fan. The semiconductor condenser, also called a semiconductor cooling chip, has a cold end and a hot end. By injecting current, it can transfer heat from the cold end to the hot end. The cold end of the semiconductor condenser is located in the water channel 202.

[0035] To dissipate heat from the hot end of the semiconductor condenser as quickly as possible and ensure its normal operation, the hot end of the semiconductor condenser is positioned within the heat-conducting fins. The exhaust fan generates convective air, which is then directed onto the heat-conducting fins; these fins facilitate heat exchange between the heat transferred from the hot end of the semiconductor condenser and the convective air.

[0036] Utilizing the heat transfer function of the semiconductor condenser, in this embodiment, the cold end of the semiconductor condenser acts within the water guide channel 202, resulting in a lower temperature for the entire water guide channel 202. Because of this lower temperature, the water guide channel 202 exhibits a strong condensation effect on water vapor. The water guide channel 202 is located at the edge of the carpet surface 101 and is in contact with it. Therefore, water vapor in the carpet surface 101 will condense into liquid water due to condensation. This liquid water can be removed using a hydrophobic composite system, achieving the goal of reducing water vapor in the carpet surface 101.

[0037] Of course, since the inner wall of the water guide channel 202 is also in contact with the air inside the vehicle cabin, it will condense the water vapor in the air inside the vehicle cabin. This condensed liquid water will be collected by the water guide channel 202 and flow into the water collection box. This achieves the goal of reducing the water vapor in the air inside the vehicle cabin.

[0038] To achieve efficient dehumidification, a collaborative control system is also provided. This system mainly coordinates the control of the underfloor heating layer 301 or the dehumidification system to reduce the return of water vapor to the carpet surface 101.

[0039] Since the primary application scenario involves dehumidification during winter, the underfloor heating layer 301 will operate to ensure warmth within the vehicle cabin. To achieve efficient dehumidification in this application scenario, this application also provides a dehumidification control method. In the dehumidification control method, the coordinated control system includes a control unit and a humidity sensor unit. The humidity sensor unit is used to collect the humidity value of the carpet surface layer 101 and transmit the humidity value to the control unit.

[0040] The dehumidification control method operates in the control unit. When the dehumidification control method is run, the execution steps include: Step 1, obtaining the current humidity value of the carpet surface 101 from the humidity sensor and recording the humidity value as the target humidity value.

[0041] Step 2: Retrieve the preset first humidity threshold and second humidity threshold. The first humidity threshold is greater than the second humidity threshold.

[0042] Step 3: Compare the target humidity value with the first humidity threshold and the second humidity threshold respectively.

[0043] Step 4: When the target humidity value is greater than or equal to the first humidity threshold, the dehumidification system is activated, and the floor heating layer 301 is controlled to operate in a low heating power state to reduce the heat output of the floor heating layer 301. When the target humidity value is less than or equal to the second humidity threshold, the dehumidification system is stopped, and the floor heating layer 301 is controlled to return from the low heating power state to the normal heating power state to restore the heat output of the floor heating layer 301.

[0044] In some specific embodiments, the first humidity threshold is set to 30%, and the second humidity threshold is set to 15%. It should be noted that humidity here refers to relative humidity. Therefore, in some specific embodiments, when the control unit operates the dehumidification control method, it communicates with a humidity sensor to determine the current humidity value of the carpet surface 101, i.e., obtains the target humidity value. The control unit has an internal storage unit. This storage unit pre-stores the first and second humidity thresholds. The control unit retrieves the first and second humidity thresholds from the storage unit. The target humidity value is compared with both the first and second humidity thresholds to obtain a comparison result. The comparison result is then used for further judgment.

[0045] The underfloor heating layer 301 uses a flexible heating film, supporting both normal heating power and low heating power operating modes. Therefore, when the dehumidification system is required, the underfloor heating layer 301 needs to operate in low heating power mode to reduce its heat output and avoid affecting the dehumidification system's operation. Conversely, when humidity decreases, i.e., when the target humidity value is less than or equal to the second humidity threshold, to maintain warmth in the vehicle cabin, the dehumidification system needs to be stopped, and the underfloor heating layer 301 needs to be restored from the low heating power state to the normal heating power state to restore its heat output.

[0046] For the structure of hydrophobic composite systems, refer to Figure 3 , Figure 3 This is a schematic diagram illustrating the connection relationship between the hydrophobic composite system and other components in another embodiment. In another embodiment, the hydrophobic composite system includes: a micro / nano hydrophobic coating 201 and a capillary water-conducting network 203. The micro / nano hydrophobic coating 201 is disposed on the lower side of the carpet surface 101. The capillary water-conducting network 203 is in contact with the micro / nano hydrophobic coating 201. The micro / nano hydrophobic coating 201 is used to repel water droplets into the capillary water-conducting network 203. The capillary water-conducting network 203 is used to carry the water droplets repelled from the micro / nano hydrophobic coating 201 and transfer them to a water collection box.

[0047] In this embodiment, since the micro / nano hydrophobic coating 201 is located on the underside of the carpet surface 101, water in the carpet surface 101 will move into the micro / nano hydrophobic coating 201 due to gravity. Due to the properties of the micro / nano hydrophobic coating 201, it utilizes its superhydrophobic surface to rapidly form water droplets. These droplets flow along the gaps in the array of protrusions on the surface of the micro / nano hydrophobic coating 201 towards the capillary network 203. The capillary network 203 then guides the water into the collection box through capillary action.

[0048] In some further specific embodiments, the dehumidification system includes an adsorption dehumidification module, which is used to adsorb moisture from the carpet surface 101 or from the air.

[0049] In some further specific embodiments, the dehumidifying automotive floor heating system also includes a thermal insulation layer 302, which is disposed below the floor heating layer 301; the thermal insulation layer 302 is used to reduce the heat loss from the floor heating layer 301 to the vehicle chassis.

[0050] In some further specific embodiments, the micro / nano hydrophobic coating 201 is prepared using a polytetrafluoroethylene-silica composite modified material with a thickness of 50 μm to 100 μm. The surface is provided with a micron-scale bump array, a static contact angle ≥150°, and a roll-off angle ≤10°. This structure facilitates the repellency of liquid water.

[0051] Those skilled in the art generally believe that the main function of automotive underfloor heating is heating, while dehumidification can be achieved solely through the air conditioning system. However, this invention creatively recognizes that underfloor heating accelerates the evaporation of residual liquid water, leading to a surge in air humidity and consequently increasing the burden on the air conditioning system. Therefore, this application introduces liquid water source interception to directly remove liquid water from the carpet surface 101. Furthermore, it adds the capture of moisture from the carpet surface 101 or the air. This hybrid strategy of liquid water source interception and gaseous water capture not only solves the problem of humidity rebound during the heating process, which increases the burden on the air conditioning system, but also unexpectedly reveals that the reduced thermal conductivity of the air after dehumidification allows the heat generated by the underfloor heating layer 301 to be more concentrated on the human body rather than wasted on heating humid air, thus increasing the perceived temperature for occupants and enhancing comfort. This is particularly suitable for winter rainy and snowy weather scenarios.
