Description

Technical Field

[0001] This invention relates to a vehicle dehumidification device and a vehicle air conditioning system. Background Technology

[0002] Automotive dehumidifiers can draw in air from inside the vehicle and dehumidify it to control the humidity inside the vehicle. However, when an automotive dehumidifier is installed independently, it will increase the number of components required in the vehicle. Furthermore, the configuration of the three air duct systems of the automotive dehumidifier—air intake, dehumidified air, and humidified exhaust—will also affect the component layout of other systems in the vehicle. Therefore, there is a need to consider integrating the automotive dehumidifier with other systems into a single integrated system component for installation.

[0003] On the other hand, automotive air conditioning systems are essential equipment in vehicles with enclosed cabin structures, used to regulate the ambient temperature inside the cabin, such as providing a cool or warm cabin temperature. When a dehumidifier is installed in the automotive air conditioning system, if air from the air intake of the automotive air conditioning system (including external air intake and internal air intake) passes through the dehumidifier, the external air may contain water droplets, which may degrade the membrane elements of the dehumidifier. Therefore, water-repellent countermeasures are required.

[0006] [Patent Document 1] Japanese Patent Application Publication No. 2016-064695 Summary of the Invention

[0007] This invention provides a vehicle dehumidification device and a vehicle air conditioning system. The vehicle dehumidification device can be used as a humidity control unit in a vehicle air conditioning system and has good reliability.

[0008] This invention provides a vehicle dehumidification device. During the dehumidification process, a dehumidification element dehumidifies the air inside the vehicle. During the regeneration process, the dehumidification element, after absorbing moisture, is heated, and the heated humidified air flows out of the vehicle through the dehumidification element to regenerate it. The vehicle dehumidification device is located upstream of the blower of the vehicle's air conditioning system, and its air inlet is located on the side of the dashboard separating the drive compartment and the passenger compartment. This ensures that only air from inside the vehicle can be introduced into the air inlet of the vehicle dehumidification device through the blower and then pass through the dehumidification element.

[0009] This invention provides an automotive air conditioning system, comprising: an air conditioning unit including an air intake end and a blower; and an automotive dehumidifier as a humidity control unit. The automotive dehumidifier has a dehumidifying element disposed upstream of the blower, and the air intake of the automotive dehumidifier is disposed on the side of the dashboard separating the drive compartment and the passenger compartment, so that only interior air can be introduced into the air intake of the automotive dehumidifier through the blower and then pass through the dehumidifying element.

[0010] In one embodiment of the present invention, the dehumidification element includes a first dehumidification element and a second dehumidification element, wherein when the vehicle dehumidification device dehumidifies the air inside the vehicle through one of the first dehumidification element and the second dehumidification element, the vehicle dehumidification device heats the other of the first dehumidification element and the second dehumidification element to regenerate the other of the first dehumidification element and the second dehumidification element.

[0011] In one embodiment of the present invention, the above-mentioned vehicle dehumidification device further includes: an airflow regulating mechanism located between the air inlets of the first dehumidification element and the second dehumidification element and the blower, for forming a first air inlet channel and a second air inlet channel respectively. The first air inlet channel connects the air inlet of the first dehumidification element and the blower, and the second air inlet channel connects the air inlet of the second dehumidification element and the blower. When the vehicle dehumidification device dehumidifies the air inside the vehicle through the first dehumidification element, the vehicle dehumidification device causes the airflow regulating mechanism to open the first air inlet channel and close the second air inlet channel. When the vehicle dehumidification device dehumidifies the air inside the vehicle through the second dehumidification element, the vehicle dehumidification device causes the airflow regulating mechanism to open the second air inlet channel and close the first air inlet channel. The air inside the vehicle that enters the blower through the air inlet of either the first dehumidification element or the second dehumidification element merges with the air inside the vehicle that enters the blower through the air inlet end and the outside air after passing through the airflow regulating mechanism.

[0012] In one embodiment of the present invention, the airflow regulating mechanism includes a damper structure capable of adjusting the opening degree, and the damper structure includes a first damper structure and a second damper structure. The first damper structure is used to open and close the first air intake passage and adjust the airflow of the in-vehicle air entering the blower through the first dehumidification element. The second damper structure is used to open and close the second air intake passage and adjust the airflow of the in-vehicle air entering the blower through the second dehumidification element. When the vehicle dehumidification device dehumidifies the in-vehicle air through the first dehumidification element, the airflow regulating mechanism opens the first damper structure to open the first air intake passage and closes the second damper structure to close the second air intake passage. When the vehicle dehumidification device dehumidifies the in-vehicle air through the second dehumidification element, the airflow regulating mechanism opens the second damper structure to open the second air intake passage and closes the first damper structure to close the first air intake passage.

[0013] In one embodiment of the present invention, the aforementioned airflow regulating mechanism includes a movable window structure with multiple openings, including a first opening and a second opening. The first opening of the airflow regulating mechanism forms a first air inlet channel when it intersects the partition wall region between the air inlet of the first dehumidifying element and the blower. The second opening forms a second air inlet channel when it intersects the partition wall region between the air inlet of the second dehumidifying element and the blower. Furthermore, when the vehicle dehumidifying device dehumidifies the air inside the vehicle through the first dehumidifying element, the vehicle dehumidifying device causes the first opening of the airflow regulating mechanism to intersect the first dehumidifying element. The partition area between the air inlet and the blower opens the first air intake passage, and the second opening of the air volume regulating mechanism moves away from the partition area between the air inlet and the blower of the second dehumidifying element to close the second air intake passage. When the vehicle dehumidifying device dehumidifies the air inside the vehicle through the second dehumidifying element, the vehicle dehumidifying device causes the second opening of the air volume regulating mechanism to cut into the partition area between the air inlet and the blower of the second dehumidifying element to open the second air intake passage, and causes the first opening of the air volume regulating mechanism to move away from the partition area between the air inlet and the blower of the first dehumidifying element to close the first air intake passage.

[0014] In one embodiment of the present invention, the above-mentioned vehicle dehumidification device further includes a regeneration fan. When the vehicle dehumidification device heats up to regenerate the other of the first dehumidification element and the second dehumidification element, the vehicle dehumidification device activates the regeneration fan so that the heated humidified air generated during the regeneration process of the first dehumidification element and the other of the second dehumidification element can flow out of the vehicle dehumidification device through the regeneration fan.

[0015] In one embodiment of the present invention, the above-mentioned regeneration fan includes a first regeneration fan and a second regeneration fan, wherein the first regeneration fan is disposed next to the air chamber of the first dehumidifying element and is used to allow the heated humidified air generated during the regeneration process of the first dehumidifying element to flow out of the vehicle dehumidifying device, and the second regeneration fan is disposed next to the air chamber of the second dehumidifying element and is used to allow the heated humidified air generated during the regeneration process of the second dehumidifying element to flow out of the vehicle dehumidifying device.

[0016] In one embodiment of the present invention, the first dehumidifying element is connected to the drain outlet of the air conditioning unit through the first exhaust channel, the second dehumidifying element is connected to the drain outlet of the air conditioning unit through the second exhaust channel, and the regeneration fan is located downstream of the first exhaust channel and the second exhaust channel after they merge. When the vehicle dehumidifying device regenerates the first dehumidifying element, the vehicle dehumidifying device opens the first exhaust channel and closes the second exhaust channel. When the vehicle dehumidifying device regenerates the second dehumidifying element, the vehicle dehumidifying device opens the second exhaust channel and closes the first exhaust channel.

[0017] In one embodiment of the present invention, the humidified air that has been heated flows out of the vehicle dehumidifier and is discharged outside the vehicle through the drain outlet of the air conditioning unit.

[0018] In one embodiment of the present invention, the air conditioning unit further includes a filter, wherein the filter is located between the air intake end and the blower, and the air intake end of the air conditioning unit includes an external air intake end and an internal air intake end, the external air intake end is used to draw in air from outside the vehicle, the internal air intake end is used to draw in air from inside the vehicle, and a partition is formed between the air intake end and the filter to separate the air inside the vehicle and the air outside the vehicle.

[0019] In one embodiment of the present invention, the air inlet of the above-mentioned vehicle dehumidification device is provided separately from the external air inlet and the internal air inlet of the air conditioning unit.

[0020] In one embodiment of the present invention, the above-mentioned vehicle dehumidification device is located between the blower and the filter of the air conditioning unit.

[0021] Based on the above, in an embodiment of the vehicle air conditioning system of the present invention, by configuring the vehicle dehumidifier, which serves as a humidity regulating unit, upstream of the blower of the vehicle air conditioning system and installing the air inlet of the vehicle dehumidifier on the dashboard side, the vehicle dehumidifier can control the humidity of the comfortable air provided by the vehicle air conditioning system by only drawing in air from inside the vehicle. This prevents external splashes of water or water droplets, or beverages spilled from inside the vehicle, from affecting the dehumidifying material through the air inlet, thereby reducing the risk of component degradation of the vehicle dehumidifier and thus achieving good reliability. Furthermore, by configuring the vehicle dehumidifier along the path of the ductwork of the vehicle air conditioning system, the vehicle-mounted performance of the vehicle dehumidifier can be improved. Since the airflow supplied to the vehicle by the vehicle air conditioning system remains unchanged, the thermal comfort of the human body is ensured through airflow, and the performance of the vehicle air conditioning system related to noise, vibration, and harshness (NVH) can be maintained at the same level as the prior art. Furthermore, the vehicle dehumidifier, through the installation of a regenerative fan, can reliably discharge heated and humidified air to the outside in a simple structure under negative pressure upstream of the blower of the vehicle's air conditioning system. Thus, by sharing the blower, housing, and part of the ductwork structure with the vehicle's air conditioning system, the vehicle dehumidifier can be integrated into the system as a humidity control unit, simplifying its structure, improving vehicle performance, and reducing the size of the air conditioning system. Simultaneously, by simplifying the necessary components of the air conditioning system, lower power consumption can be ensured while minimizing cost increases.

[0075] Please refer to Figure 1A In this embodiment, the vehicle air conditioning system 200 includes an air conditioning unit 210 and a vehicle dehumidifier 100 as a humidity control unit. Specifically, the air conditioning unit 210 (heating, ventilation and air conditioning, HVAC) includes an air intake end 211, a filter 212, a blower 213, an air duct mechanism 214, a temperature control module 215, and an air outlet end 216. Further, as... Figures 1A to 2CAs shown, the filter 212 is located between the air intake end 211 and the blower 213. The air intake end 211 of the air conditioning unit 210 includes an external air intake end 211a and an internal air intake end 211c. The external air intake end 211a is used to draw in outside air (OAR), and the internal air intake end 211c is used to draw in inside air (IAR). A partition 211b is formed between the air intake end 211 and the filter 212 to separate the inside air (IAR) and outside air (OAR). The blower 213 is installed in the duct mechanism 214 and can be controlled to start, creating a negative pressure environment upstream of the blower 213 and a positive pressure environment downstream of the blower 213. This generates an airflow from the external air intake end 211a or the internal air intake end 211c through the duct mechanism 214 and the temperature control module 215 to the air outlet end 216. Furthermore, in this embodiment, as... Figure 1B and Figure 1C As shown, the temperature control module 215 includes a cooling unit 215a and a heating unit 215c, and can cool or heat the air flowing into the temperature control module 215 through the blower 213 as needed to provide a comfortable ambient temperature inside the vehicle.

[0076] Generally speaking, such as Figure 1B As shown, the refrigeration unit 215a of the temperature control module 215 can be the evaporator of the refrigeration cycle system, having an inlet for refrigerant inflow and an outlet for refrigerant outflow, and is connected to the compressor 215b to allow refrigerant circulation. During the air cooling process, the refrigeration unit 215a causes the air from the blower 213 to exchange heat with the refrigerant, thus cooling the air. During the aforementioned cooling process, i.e., in the cooling mode of the vehicle air conditioning system 200, since the moisture in the air is simultaneously converted into water droplets, the refrigeration unit 215a of the temperature control module 215 can also function as a dehumidifier. Figure 1B As shown, a comfortable humidity level can be achieved inside the vehicle without activating the vehicle dehumidifier 100.

[0077] On the other hand, during the process of heating the airflow, i.e., in the warming mode of the vehicle air conditioning system 200, the air from the blower 213 can be heated by shutting down the refrigeration unit 215a and compressor 215b of the refrigeration cycle system and activating the heating unit 215c. For example, in this embodiment, the heating unit 215c can be a heater that can directly heat air using a thermistor with a positive temperature coefficient (PTC), a heater core in which refrigerant heated by engine exhaust heat dissipates heat through heat exchange with the passing air, or a heater core in which refrigerant heated by an electric heater dissipates heat through heat exchange with the passing air. Furthermore, when the air conditioning unit 210 is a heat pump type, the heating unit 215c can be an indoor condenser, into which the refrigerant compressed and heated by the compressor 215b flows. In this case, when the air from the blower 213 passes through the heating unit 215c, it can exchange heat with the high-temperature, high-pressure refrigerant in the indoor condenser, allowing the refrigerant to dissipate heat and thus raising the air temperature.

[0078] However, in the heating mode of the vehicle air conditioning system 200, when the outside temperature is low and the cooling unit 215a is operating, frost will form on the cooling unit 215a, thus the cooling unit 215a cannot be used for dehumidification. Therefore, as Figure 1C As shown, dehumidification needs to be achieved by activating the vehicle dehumidifier 100 to maintain a comfortable humidity level inside the vehicle. Furthermore, as... Figure 1A , Figure 3A and Figure 3B As shown, in this embodiment, the vehicle dehumidifier 100 includes a dehumidifying element 110. For example, such as Figure 3A and Figure 3BAs shown, in this embodiment, the dehumidifying element 110 is a thin dehumidifying element, which may contain HASClay®, a composite material made by synthesizing amorphous aluminum silicate and low-crystallinity clay, as an adsorbent to adsorb moisture in the air and thus dehumidify the air passing through the dehumidifying element 110. This composite material HASClay® has the advantages of high safety, high adsorption performance in a low humidity range, high-speed adsorption of moisture or regeneration cycle, high regeneration efficiency, low power consumption regeneration, low ventilation resistance, high reliability, high heat resistance, light weight, and low cost. In addition, as an adsorbent, besides the composite material HASClay®, zeolite, silica gel, and other polymeric adsorbents with high hygroscopicity under specified humidity conditions can also be used. Furthermore, the thin dehumidifying element can be, for example, a honeycomb substrate or a mesh substrate, as long as the component can be heated by electricity to support the desiccant. Furthermore, the thin desiccant element can also have another type of structure, in which a predetermined desiccant is carried on a folded, breathable sheet to form a moisture-absorbing section, and the heater (heating section) of the thin desiccant element directly contacts and heats the moisture-absorbing section. In this case, the heater is a plate-shaped heater extending along the airflow direction and directly contacts the moisture-absorbing section along almost the entire longitudinal direction. Moreover, by using the structural configuration of the thin desiccant element, the vehicle dehumidification device 100 can achieve the smallest system volume while having the same desiccant capacity. That is, although the system volume will vary depending on the desiccant capacity, since the thin desiccant elements can be arranged in series, even if multiple thin desiccant elements are arranged in the vehicle desiccant device 100 to increase the desiccant capacity, the increase in size due to series connection can be controlled to a small extent.

[0079] On the other hand, as the amount of adsorbed moisture increases over time, its adsorption capacity gradually decreases. In this situation, the vehicle dehumidifier 100 performs a regeneration process for the dehumidifier element 110. This is achieved by heating the moisture-absorbing dehumidifier element 110 with a built-in heater 130, thereby desorbing the moisture from the adsorbent. This replaces air heating, as the built-in heater 130 directly heats the dehumidifier element 110, allowing for efficient regeneration of the dehumidifier element 110 in a short time. Furthermore, in this embodiment, the built-in heater 130 has a positive temperature coefficient (PTC) thermistor, whose resistance increases with temperature. Therefore, the built-in heater 130 has a self-regulating characteristic that suppresses temperature rise during the regeneration process at a predetermined temperature. Thus, while providing the necessary regeneration temperature to the dehumidifier element 110, it simultaneously suppresses smoke and fire caused by abnormal heating. In addition, the vehicle dehumidifier 100 may be equipped with a regeneration fan 140 so that the heated humidified air MAR can leave the vehicle dehumidifier 100 so that the adsorption capacity of the dehumidifier element 110 can be restored, thereby regenerating the dehumidifier element 110.

[0080] And, as Figures 1A to 2C As shown, in this embodiment, the vehicle dehumidifier 100 is located between the blower 213 and the filter 212 of the air conditioning unit 210, and can be installed upstream of the blower 213 in the duct structure 214. Thus, by installing the vehicle dehumidifier 100 downstream of the filter 212, the maintainability required in case of malfunction can be improved, and the blower 213 can simultaneously create a negative pressure environment at the air inlet IT of the vehicle dehumidifier 100, causing air to flow from the air inlet IT of the vehicle dehumidifier 100 to the blower 213.

[0081] And, as Figures 1A to 2C As shown, the air inlet IT of the vehicle dehumidifier 100 is separately provided from the outer air inlet 211a and inner air inlet 211c of the air conditioning unit 210. The air inlet IT of the vehicle dehumidifier 100 is located on the side of the dashboard DB that separates the drive compartment MR and the passenger compartment. This allows only the air inside the vehicle IAR to be introduced into the air inlet IT of the vehicle dehumidifier 100 through the blower 213 and then through the dehumidification element 110, thus preventing the air outside the vehicle OAR from being introduced into the vehicle dehumidifier 100.

[0082] In addition, such as Figure 1AAs shown, the interior air IAR entering the blower 213 through the air inlet IT of the vehicle dehumidifier 100 can be combined with the interior air IAR entering the blower 213 through the air inlet 211 and the exterior air OAR, and then flow through the duct mechanism 214 and the temperature control module 215 before returning to the vehicle interior. Thus, the vehicle air conditioning system 200 can control the humidity of the air flowing out of the outlet 216 by mixing the interior air IAR dehumidified by the vehicle dehumidifier 100 with the interior air IAR entering the blower 213 through the air inlet 211 and the exterior air OAR, thereby enabling the vehicle dehumidifier 100 to be used as a humidity control unit of the vehicle air conditioning system 200. Furthermore, since the temperature of the air inside the vehicle (IAR) is higher than the temperature of the air outside the vehicle (OAR), and the vehicle dehumidifier 100 only needs to heat the air inside the vehicle (IAR) when performing the regeneration process of the dehumidification element 110, the power consumption of the built-in heater 130 installed in the vehicle dehumidifier 100 can be suppressed. In addition, in this embodiment, the heated humidified air (MAR) can also be discharged outside the vehicle through the drain outlet 217 of the temperature control module 215 of the air conditioning unit 210 after flowing out of the vehicle dehumidifier 100. Thus, the humidified air (MAR) of the vehicle dehumidifier 100 can share the drain outlet 217 with the condensate (W) formed by the temperature control module 215 of the air conditioning unit 210 during the air cooling process, without the need to install new holes in the body of the vehicle air conditioning system 200, thereby maintaining quiet performance at low cost.

[0083] The following will be paired Figures 3A to 4C The control process and specific structure of the vehicle dehumidifier 100 as a humidity regulating unit of the vehicle air conditioning system 200 will be further explained.

[0084] Specifically, such as Figure 1A , Figures 3A to 4CAs shown, in this embodiment, the dehumidification element 110 includes a first dehumidification element 111 and a second dehumidification element 112, and the vehicle dehumidification device 100 also includes an airflow adjustment mechanism 120. The airflow adjustment mechanism 120 is located between the air inlets IT of the first dehumidification element 111 and the second dehumidification element 112 and the blower 213, and is disposed on one side of the air chamber AC of the first dehumidification element 111 and the second dehumidification element 112, and can be used to form a first air inlet channel AP1 and a second air inlet channel AP2 respectively, wherein the first air inlet channel AP1 connects the air inlet IT of the first dehumidification element 111 and the blower 213, and the second air inlet channel AP2 connects the air inlet IT of the second dehumidification element 112 and the blower 213. For example, in this embodiment, the airflow regulating mechanism 120 includes an actuator 121 and a damper structure 122 with adjustable opening. The actuator 121 is connected to the damper structure 122 and is used to control the opening of the damper structure 122 to adjust the airflow of the vehicle interior air IAR entering the blower 213 through either the first dehumidifying element 111 or the second dehumidifying element 112.

[0085] Furthermore, the damper structure 122 includes a first damper structure 122a and a second damper structure 122b. The first damper structure 122a is located between the air inlet IT of the first dehumidifying element 111 and the blower 213, and is situated on one side of the air chamber AC of the first dehumidifying element 111. It can be used to open and close the first air inlet passage AP1 and adjust the airflow of the in-vehicle air IAR entering the blower 213 through the first dehumidifying element 111. The second damper structure 122b is located between the air inlet IT of the second dehumidifying element 112 and the blower 213, and is situated on one side of the air chamber AC of the second dehumidifying element 112. It can be used to open and close the second air inlet passage AP2 and adjust the airflow of the in-vehicle air IAR entering the blower 213 through the second dehumidifying element 112. Thus, as... Figures 3A to 4C As shown, the in-vehicle air IAR that enters the blower 213 through the air inlet IT of either the first dehumidifying element 111 or the second dehumidifying element 112 can be combined with the in-vehicle air IAR that enters the blower 213 through the air inlet end 211 and the outside air OAR with an appropriate airflow after passing through the airflow regulating mechanism 120.

[0086] On the other hand, such as Figure 1A , Figures 4A to 4CAs shown, in this embodiment, a first heater 131 and a second heater 132 are provided in the first dehumidifying element 111 and the second dehumidifying element 112. When the vehicle dehumidifying device 100 heats the first dehumidifying element 111 through the first heater 131 to regenerate the first dehumidifying element 111, or heats the second dehumidifying element 112 through the second heater 132 to regenerate the second dehumidifying element 112, the vehicle dehumidifying device 100 starts the regeneration fan 140. Correspondingly, the heated humidified air MAR generated during the regeneration process of the first dehumidifying element 111 or the second dehumidifying element 112 can flow out of the vehicle dehumidifying device 100 through the regeneration fan 140 and be discharged outside the vehicle through the drain outlet 217 of the temperature control module 215 of the air conditioning unit 210.

[0087] For example, in this embodiment, multiple regeneration fans 140 may be provided; that is, the regeneration fans 140 include a first regeneration fan 141 and a second regeneration fan 142. Specifically, as... Figures 3B to 4C As shown, in this embodiment, the first regenerative fan 141 is disposed next to the air chamber AC of the first dehumidifying element 111, and it and the first damper structure 122a are respectively located on different sides of the air chamber AC of the first dehumidifying element 111, and as... Figure 2C As shown, the air chamber AC of the first dehumidifying element 111 can be connected to the drain outlet 217 of the air conditioning unit 210 via the first regeneration fan 141 and the first exhaust passage 143. Thus, when the first regeneration fan 141 is activated during the regeneration process of the first dehumidifying element 111, the heated humidified air MAR generated during the regeneration process of the first dehumidifying element 111 flows out of the vehicle dehumidifier 100, and is discharged outside the vehicle after passing through the first exhaust passage 143 and the drain outlet 217 of the air conditioning unit 210. Similarly, the second regeneration fan 142 is disposed next to the air chamber AC of the second dehumidifying element 112, and it and the second damper structure 122b are located on different sides of the air chamber AC of the second dehumidifying element 112, and as shown... Figure 2C As shown, the air chamber AC of the second dehumidifying element 112 can be connected to the drain port 217 of the air conditioning unit 210 through the second regeneration fan 142 and the second exhaust passage 144. Thus, when the second regeneration fan 142 is activated during the regeneration process of the second dehumidifying element 112, the heated humidified air MAR generated during the regeneration process of the second dehumidifying element 112 can also flow out of the vehicle dehumidifier 100, and after flowing through the second exhaust passage 144 and the drain port 217 of the air conditioning unit 210, it can be discharged outside the vehicle.

[0088] Thus, by configuring the regenerative fan 140, even if the vehicle dehumidifier 100 is installed upstream of the blower 213, the regenerative fan 140 can prevent the humidified air MAR containing water vapor from either the first dehumidifying element 111 or the second dehumidifying element 112 from being drawn by the blower 213 and mixed with the dehumidified air from the other of the first dehumidifying element 111 and the second dehumidifying element 112 through regeneration circulation, thereby maintaining the dehumidification performance of the vehicle dehumidifier 100.

[0089] Furthermore, such as Figure 4A As shown, in this embodiment, when the vehicle air conditioning system 200 cools the air, i.e., in the cooling mode of the vehicle air conditioning system 200, the vehicle dehumidifier 100 does not operate. At this time, in the vehicle dehumidifier 100, the first damper structure 122a and the second damper structure 122b of the airflow regulating mechanism 120, the first heater 131 and the second heater 132, and the first regeneration fan 141 and the second regeneration fan 142 of the regeneration fan 140 are all in the closed state.

[0090] On the other hand, when the vehicle air conditioning system 200 heats the air, that is, in the heating mode of the vehicle air conditioning system 200, the vehicle dehumidifier 100 operates, and alternately switches the opening states of the first damper structure 122a and the second damper structure 122b of the air volume regulating mechanism 120, the first heater 131 and the second heater 132, and the first regenerating fan 141 and the second regenerating fan 142 of the regenerating fan 140.

[0091] For example, such as Figure 4B As shown, in this embodiment, when the vehicle dehumidifier 100 dehumidifies the in-vehicle air (IAR) through the first dehumidifying element 111, the vehicle dehumidifier 100 causes the airflow regulating mechanism 120 to open the first damper structure 122a to open the first air inlet passage AP1, and close the second damper structure 122b to close the second air inlet passage AP2. Simultaneously, the vehicle dehumidifier 100 can activate the second heater 132 to heat the second dehumidifying element 112 to regenerate it, and activate the second regeneration fan 142 to allow the heated humidified air (MAR) generated during the regeneration of the second dehumidifying element 112 to flow out of the vehicle dehumidifier 100.

[0092] Similarly, such as Figure 4CAs shown, when the vehicle dehumidifier 100 dehumidifies the in-vehicle air (IAR) through the second dehumidifying element 112, the vehicle dehumidifier 100 causes the airflow regulating mechanism 120 to open the second damper structure 122b to open the second air intake passage AP2, and close the first damper structure 122a to close the first air intake passage AP1. Simultaneously, the vehicle dehumidifier 100 can activate the first heater 131 to heat the first dehumidifying element 111, thereby regenerating the first dehumidifying element 111, and activate the first regeneration fan 141, allowing the heated humidified air (MAR) generated during the regeneration process of the first dehumidifying element 111 to flow out of the vehicle dehumidifier 100.

[0093] Thus, the vehicle dehumidifier 100, through the synchronous switching of the first damper structure 122a and the second damper structure 122b, the first heater 131 and the second heater 132, and the first regeneration fan 141 and the second regeneration fan 142, can alternately dehumidify the in-vehicle air (IAR) and regenerate either the first dehumidifier 111 or the second dehumidifier 112 simultaneously. That is, when the vehicle dehumidifier 100 dehumidifies the in-vehicle air (IAR) through one of the first dehumidifier 111 and the second dehumidifier 112, it can simultaneously regenerate the other of the first dehumidifier 111 and the second dehumidifier 112. Furthermore, since the first damper structure 122a and the second damper structure 122b can be used to adjust the airflow of the in-vehicle air IAR entering the blower 213 through the first dehumidifying element 111 and the second dehumidifying element 112, by adjusting the opening of the first damper structure 122a and the second damper structure 122b, during the process of the vehicle dehumidification device 100 dehumidifying and regenerating the in-vehicle air IAR through either the first dehumidifying element 111 or the second dehumidifying element 112, the air chamber AC can be adjusted to deliver air at a predetermined airflow and retain a predetermined amount of residual air for humidification.

[0094] Thus, the vehicle dehumidifier 100 can continuously dehumidify the in-vehicle air (IAR) by alternately using the first dehumidifying element 111 and the second dehumidifying element 112, and can also intermittently regenerate the first dehumidifying element 111 and the second dehumidifying element 112, thereby maintaining good dehumidification performance at all times. Furthermore, by shortening the cycle of alternating between the first dehumidifying element 111 and the second dehumidifying element 112 for dehumidifying and regenerating the in-vehicle air (IAR), the required moisture-absorbing material can be reduced, thereby lowering product costs and saving space. For example, in this embodiment, the time for the vehicle dehumidifier 100 to alternately dehumidify the in-vehicle air (IAR) using the first dehumidifying element 111 and the second dehumidifying element 112, and the time for regenerating the first dehumidifying element 111 and the second dehumidifying element 112, are each approximately 3 minutes, but the invention is not limited to this. In other embodiments, the vehicle dehumidification device 100 can alternately switch the dehumidification time cycle and the regeneration processing time cycle of the first dehumidification element 111 and the second dehumidification element 112 according to actual needs.

[0095] In this way, by configuring the vehicle dehumidifier 100, which serves as a humidity control unit, upstream of the blower 213 of the vehicle air conditioning system 200, and by mounting the air intake IT of the vehicle dehumidifier 100 on the dashboard DB side, the vehicle dehumidifier 100 can control the humidity of the comfortable air provided by the vehicle air conditioning system 200 by only drawing in the air inside the vehicle IAR. This prevents external splashes or water droplets, or beverages spilled from inside the vehicle, from affecting the dehumidifying material through the air intake IT, thereby reducing the risk of component degradation of the vehicle dehumidifier 100 and thus achieving good reliability.

[0096] Furthermore, by placing the vehicle dehumidifier 100 along the path of the ductwork 214 of the vehicle air conditioning system 200, the vehicle performance of the vehicle dehumidifier 100 can be improved. Since the airflow supplied to the vehicle interior by the vehicle air conditioning system remains unchanged, thermal comfort for the human body is ensured through airflow, and the performance related to noise, vibration, and harshness (NVH) in the vehicle air conditioning system can be maintained at the same level as existing technologies. In addition, through the installation of the regenerative fan 140, the vehicle dehumidifier 100 can reliably discharge heated and humidified air (MAR) to the outside in a simple structure under negative pressure conditions upstream of the blower 213 of the vehicle air conditioning system 200.

[0097] Thus, by sharing the blower 213, housing, and part of the ductwork 214 with the vehicle air conditioning system 200, the vehicle dehumidifier 100 can be integrated into the vehicle air conditioning system 200 as a humidity control unit. This simplifies the structure of the vehicle dehumidifier 100, improves vehicle performance, and reduces the size of the vehicle air conditioning system 200. Furthermore, by simplifying the necessary components of the vehicle air conditioning system 200, lower power consumption can be ensured while minimizing cost increases.

[0098] Furthermore, it is worth noting that in the aforementioned embodiments, multiple regeneration fans 140 are provided, but the present invention is not limited thereto; in other embodiments, only one regeneration fan 140 may be provided. For example, in another embodiment not shown, the regeneration fan 140 may be located downstream of the confluence of the first exhaust channel 143 and the second exhaust channel 144, and a first air valve and a second air valve may be respectively provided upstream of the confluence of the first exhaust channel 143 and the second exhaust channel 144. When the vehicle dehumidifier 100 regenerates the first dehumidifying element 111, the vehicle dehumidifier 100 may open the first air valve to open the first exhaust channel 143 and close the second air valve to close the second exhaust channel 144. When the vehicle dehumidifier 100 regenerates the second dehumidifying element 112, the vehicle dehumidifier 100 may open the second air valve to open the second exhaust channel 144 and close the first air valve to close the first exhaust channel 143. Thus, it is not necessary to provide regeneration fans on the outside of the air chambers AC corresponding to the first dehumidification element 111 and the second dehumidification element 112. Instead, exhaust can be performed by the same regeneration fan 140 after the first exhaust passage 143 and the second exhaust passage 144 merge. This reduces costs and allows the vehicle dehumidification device 100 with only one regeneration fan 140 to achieve similar effects and advantages as the aforementioned vehicle dehumidification device 100, which will not be elaborated here.

[0099] Figure 5 yes Figure 1A A schematic diagram of another airflow regulating mechanism; Figures 6A to 8B It is installed in a vehicle dehumidification device. Figure 5 The diagram shows the structure of the airflow regulation mechanism in different operating modes. Please refer to... Figures 5 to 8BThe vehicle dehumidifier 500 of this embodiment is similar to the vehicle dehumidifier 100, but the differences are as follows. In this embodiment, the airflow adjustment mechanism 520 of the vehicle dehumidifier 500 includes an actuator 121 and a movable window structure 522 with multiple openings OP. The fixed side of the movable window structure 522 is, for example, the side near the filter 212, and the movable side is, for example, the side near the blower 213. The actuator 121 is connected to the movable window structure 522 and controls the position movement of the multiple openings OP so that the multiple openings OP cut into or away from one side of the air chamber AC between the air inlet IT of the first dehumidifier element 111 or the second dehumidifier element 112 and the blower 213, thereby forming or blocking the air intake passage of the vehicle dehumidifier 100, and can also adjust the airflow at the same time.

[0100] For example, such as Figure 5 As shown, in this embodiment, the movable window structure 522 includes a first opening OP1 and a second opening OP2. Furthermore, as... Figures 7A to 8B As shown, when the first opening OP1 of the movable window structure 522 is inserted into the partition region R1 on one side of the air chamber AC between the air inlet IT of the first dehumidifying element 111 and the blower 213, a first air inlet channel AP1 is formed. When the second opening OP2 is inserted into the partition region R2 on one side of the air chamber AC between the air inlet IT of the second dehumidifying element 112 and the blower 213, a second air inlet channel AP2 is formed. In this way, the vehicle dehumidification device 500 allows the airflow regulating mechanism 520 to adjust the position of the multiple openings OP to alternately open one of the first air inlet channel AP1 and the second air inlet channel AP2, and correspondingly close the other of the first air inlet channel AP1 and the second air inlet channel AP2, thereby regulating the airflow.

[0101] For example, when the vehicle's air conditioning system 200 cools the air, the vehicle's dehumidifier 500 does not operate. At this time, if... Figure 6A and Figure 6B As shown, in the vehicle dehumidification device 500, the first opening OP1 and the second opening OP2 of the movable window structure 522 are not located on the partition area R1, R2 on one side of the air chamber AC between the air inlet IT of the first dehumidification element 111 or the second dehumidification element 112 and the blower 213, so the air volume adjustment mechanism 520 is in the closed state.

[0102] On the other hand, in this embodiment, when the vehicle air conditioning system 200 heats the air, i.e., in the heating mode of the vehicle air conditioning system 200, the vehicle dehumidifier 500 operates, and the airflow regulating mechanism 520 is activated. Furthermore, as... Figure 7A and Figure 7BAs shown, when the vehicle dehumidifier 500 dehumidifies the air inside the vehicle (IAR) through the first dehumidifying element 111, the vehicle dehumidifier 100 can cause the first opening OP1 of the airflow regulating mechanism 520 to engage with the partition area R1 between the air inlet IT of the first dehumidifying element 111 and the blower 213 to open the first air intake passage AP1, and cause the second opening OP2 of the airflow regulating mechanism 520 to disengage from the partition area R2 between the air inlet of the second dehumidifying element 112 and the blower 213 to close the second air intake passage AP2. Figure 8A and Figure 8B As shown, when the vehicle dehumidifier 500 dehumidifies the air inside the vehicle IAR through the second dehumidifier element 112, the vehicle dehumidifier 500 can cause the second opening OP2 of the air volume regulating mechanism 520 to cut into the partition area R2 between the air inlet IT of the second dehumidifier element 112 and the blower 213 to open the second air intake passage AP2, and cause the first opening OP1 of the air volume regulating mechanism 520 to leave the partition area R1 between the air inlet IT of the first dehumidifier element 111 and the blower 213 to close the first air intake passage AP1.

[0103] Thus, the airflow regulating mechanism 520 can adjust the airflow of the vehicle interior air IAR entering the blower 213 through the first dehumidifying element 111 and the second dehumidifying element 112 in a space-saving manner by adjusting the positions of multiple openings OP. Furthermore, since the vehicle dehumidifying device 500 has the same structure as other parts of the aforementioned vehicle dehumidifying device 100, when the vehicle dehumidifying device 500 is used… Figure 1A The vehicle air conditioning system 200 can also achieve similar effects and advantages to the aforementioned vehicle dehumidification device 100, which will not be elaborated here.

[0104] In summary, in the vehicle air conditioning system of the embodiments of the present invention, by configuring the vehicle dehumidifier, which serves as a humidity regulating unit, upstream of the blower of the vehicle air conditioning system and installing the air inlet of the vehicle dehumidifier on the dashboard side, the vehicle dehumidifier can control the humidity of the comfortable air provided by the vehicle air conditioning system by only drawing in air from inside the vehicle. This prevents external splashes of water or water droplets, or beverages spilled from inside the vehicle, from affecting the dehumidifying material through the air inlet, thereby reducing the risk of component degradation of the vehicle dehumidifier and thus achieving good reliability. Furthermore, by configuring the vehicle dehumidifier along the path of the ductwork of the vehicle air conditioning system, the vehicle-mounted performance of the vehicle dehumidifier can be improved. Since the airflow supplied to the vehicle by the vehicle air conditioning system remains unchanged, the thermal comfort of the human body is ensured through airflow, and the performance of the vehicle air conditioning system related to noise, vibration, and harshness (NVH) can be maintained at the same level as the prior art. Furthermore, the vehicle dehumidifier, through the installation of a regenerative fan, can reliably discharge heated and humidified air to the outside in a simple structure under negative pressure upstream of the blower of the vehicle's air conditioning system. Thus, by sharing the blower, housing, and part of the ductwork structure with the vehicle's air conditioning system, the vehicle dehumidifier can be integrated into the system as a humidity control unit, simplifying its structure, improving vehicle performance, and reducing the size of the air conditioning system. Simultaneously, by simplifying the necessary components of the air conditioning system, lower power consumption can be ensured while minimizing cost increases.
