[0046] The terminology used in the embodiments of this utility model is for the purpose of describing particular embodiments only and is not intended to limit the utility model. The singular forms “a,” “said,” and “the” used in the embodiments of this utility model and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise; “multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0047] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0048] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system.

[0049] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0050] RVs provide a comfortable travel experience for an increasing number of users, and also provide comprehensive protection for their travel and lifestyle.

[0051] However, during the trip, it is necessary to wash and dry underwear and other clothing, but sometimes it is inconvenient to dry them outdoors due to weather conditions. If clothes are not dried in time, they are prone to mold growth and odor due to high humidity when stored, which can affect the living environment inside the RV and, in severe cases, affect physical and mental health.

[0052] Alternatively, after camping, you need to wash dishes and cleaning cloths. After washing, the dishes are still wet and can easily develop mold and odors if left in the storage box for a long time. This will also affect the living environment inside the RV, and unclean dishes can also affect the physical and mental health of users.

[0053] In order to reduce the impact of damp clothes or undried tableware on the living environment inside the RV, an exemplary embodiment of the present invention provides a vehicle-mounted drying device 100, which can be applied to the RV 10.

[0054] A motorhome (RV), also known as a recreational vehicle or caravan, is a special type of vehicle that combines mobility and home functionality. In addition to basic automotive features, RVs also include essential home amenities such as bedding, a stove, a refrigerator, a dining table and chairs, and a bathroom. The design concept of an RV is to combine family life with travel, allowing people to enjoy home-like comforts while traveling; therefore, it is also called a "mobile home," providing travelers with comprehensive support for their travel and lifestyle.

[0055] Among them, RV 10 may include a motorhome or a towed motorhome, or RV 10 may also be an off-road motorhome or a camping motorhome, etc.

[0056] See Figure 1 As shown, the vehicle-mounted drying device 100 includes a storage chamber 110, a drying channel 120 with opening and closing function, and a heat exchanger 130.

[0057] The storage compartment 110 can be installed in the interior space of the RV 10. The interior of the storage compartment 110 is configured as a drying space for accommodating items to be dried, and one or more exhaust vents 11a with opening and closing functions can be installed on the side wall or top of the drying space.

[0058] It should be noted that the items to be dried can include various tableware or various fabrics.

[0059] The hot and humid airflow generated during the drying process of the items to be dried in the storage chamber 110 can be discharged to the outside of the vehicle through the exhaust port 11a.

[0060] An intelligent control valve is installed at the location of exhaust port 11a to enable the opening and closing function of exhaust port 11a.

[0061] A temperature detection unit (not shown in the figure) and a humidity detection unit (not shown in the figure) are installed in the drying space to form the storage chamber 110 in this example.

[0062] The temperature detection unit may include, but is not limited to, a temperature sensor or a temperature and humidity sensor, and the humidity sensor may include, but is not limited to, a humidity sensor or a temperature and humidity sensor. The temperature detection unit and the humidity detection unit are respectively installed on different side walls of the storage chamber 110 (i.e., the drying space), for example, on two opposite side walls of the storage chamber 110. The temperature detection unit is used to detect temperature-related parameters within the storage chamber 110, and the humidity detection unit is used to detect humidity-related parameters within the storage chamber 110.

[0063] It should be noted that there can be multiple temperature detection units, which are set at different positions on the same side wall of the storage chamber 110 to obtain the temperature at different positions inside the storage chamber 110. The average value of the temperatures at multiple different positions is used as the final temperature detection value to improve the accuracy of temperature detection inside the storage chamber 110.

[0064] In one example, a data fusion algorithm can also be used to integrate temperature detection data from multiple temperature sensors to improve the accuracy of temperature detection. For example, a weighted average method can be used, assigning different weights based on the accuracy and reliability of each temperature sensor, and then calculating a comprehensive temperature value, which is then used as the temperature detection value inside the storage chamber 110.

[0065] Among them, the temperature detection units located below the middle position of the storage chamber 110 have a larger weight, while the temperature detection units located above the middle position have a smaller weight.

[0066] Furthermore, there can be multiple humidity detection units, which are set at different positions on the same side wall of the storage chamber 110 to obtain the humidity at different positions in the storage chamber 110. The average value of the humidity at multiple different positions is used as the final humidity detection value to improve the accuracy of humidity detection in the storage chamber 110.

[0067] In one example, a data fusion algorithm can be used to integrate humidity detection data from multiple humidity sensors to improve the accuracy of humidity detection. For example, a weighted average method can be used, assigning different weights based on the accuracy and reliability of each humidity sensor, and then calculating a comprehensive humidity value, which is then used as the humidity detection value inside the storage chamber 110.

[0068] Among them, the humidity detection units located below the middle position of the storage chamber 110 have a larger weight, while the humidity detection units located above the middle position have a smaller weight.

[0069] In some embodiments, the storage compartment 110 may be rectangular or cubic in shape, or the shape of the storage compartment 110 may be flexibly designed according to the spatial conditions of its placement position in the RV interior.

[0070] The air outlet 121 of the drying channel 120 is connected to the drying space in the storage chamber 110. Hot air with heat can be transported to the drying space through the drying channel 120 to dry the items to be dried in the drying space.

[0071] A heat exchanger 130 surrounds the heat-generating component of the RV 10, forming a heat exchange area 131. The heat-generating component of the RV 10 can be an exhaust duct for the flow of high-temperature fumes generated by a stove during cooking. The air outlet of the heat exchange area 131 is connected to the air inlet 122 of the drying duct 120. The heat exchanger 130 exchanges heat with the heat-generating component of the RV 10 to heat the air within the heat exchange area 131. The heated air then enters the drying space of the storage chamber 110 through the drying duct 120 to dry the items within the drying space.

[0072] In this example, heat exchange component 130 is used to exchange heat with the heat-generating components of RV 10, thereby heating the air in heat exchange area 131. The heated air enters the drying space of storage chamber 110 through drying channel to quickly dry the items to be dried in the drying space, so that the items to be dried are in a dry state, preventing the items to be dried from developing mold or odors and polluting the living environment inside RV 10. This greatly enhances the versatility of RV 10's functions and effectively improves the user's experience of using RV.

[0073] like Figure 1 As shown, in some embodiments, the drying channel 120 includes a main pipe 123, a first branch pipe 124, and a third branch pipe 125.

[0074] The air inlet 122 of the main pipe 123 is connected to the air outlet of the heat exchange area 131. The main pipe 123, as the core part of the drying channel 120, plays the role of transmitting heat airflow.

[0075] The inlet of the first branch pipe 124 and the inlet of the second branch pipe 125 are both connected to the air outlet of the main pipe 123. The outlet of the first branch pipe 124 is connected to the side wall of the storage chamber 110 and communicates with the drying space.

[0076] The outlet of the second branch pipe 125 is connected to the bottom of the storage chamber 110 and communicates with the drying space.

[0077] The first branch pipe 124 and the second branch pipe 125 can transport hot air from the main pipe 123 to the drying space of the storage chamber 110, and can transport hot air from different locations to the drying space.

[0078] The air inlet of the main pipe 123 is the air inlet 122 of the drying channel 120, and the outlet of the first branch pipe 124 and the outlet of the second branch pipe 125 form the air outlet 121 of the drying channel 120.

[0079] Hot air supplied by the first branch pipe 124 enters the drying space horizontally, with the first branch pipe 124 being flush with the main pipe 123. Hot air supplied by the second branch pipe 125 enters the drying space vertically upward. This allows the two streams of hot air entering the drying space to converge at the location where the items to be dried are placed. Furthermore, the converging airflows can increase the turbulence on the fabric, thereby effectively ensuring the drying efficiency of the items to be dried.

[0080] In this example, the connection structure between the first branch pipe 124 and the second branch pipe 125 and the main pipe 123 is designed so that the drying channel 120 can ultimately transport the heat generated by the heat-generating components of the RV 10 to the drying space through different air intake positions, thereby achieving effective heat collection and transmission. This provides a reliable heat source for the items to be dried in the storage chamber 110 and also effectively improves the utilization rate of energy.

[0081] like Figure 1 As shown, in some embodiments, an air duct 126 is provided in the main pipe 123, which is used to guide the heated air in the heat exchange zone 131 to the drying space of the storage chamber 110.

[0082] The induced draft component 126 may include, but is not limited to, an induced draft fan, an axial flow fan, a centrifugal fan, etc.

[0083] In this example, through the fan blades and other structures in the air duct 126, a certain airflow pressure difference is formed on the front and rear sides of the air duct 126 when the air duct 125 rotates. This attracts the heat from the heat exchange area 131, which then flows along the main pipe 123 and through the first branch pipe 124 and the second branch pipe 125 into the drying space in the storage chamber 110. This achieves effective utilization of heat, improves the coordination between different components inside the RV, and dries the items to be dried in the storage chamber 110, or adjusts the temperature inside the storage chamber 110.

[0084] like Figure 1 As shown, in some embodiments, an electric heating element 127 is also provided in the main pipe 123. Along the flow direction of the heated air, the electric heating element 127 can be located upstream of the air duct 126, or the electric heating element 127 can also be located downstream of the air duct 126.

[0085] Among them, the electric heating element 127 can be an electric heater, which may include, but is not limited to, graphite heaters, semiconductor heaters, etc.

[0086] It should be noted that the electric heating element 127 can be used in conjunction with the stove in the RV 10 to assist in drying when the stove's heating is insufficient. Alternatively, when the stove is not available, the electric heating element 127 can be used alone to dry items in the drying space.

[0087] When the electric heating element 127 is located upstream of the exhaust fan 126, it can preheat or heat the air entering the main pipe 123. For the RV 10 operating in low-temperature environments, cold air may cause problems such as condensation and decreased equipment performance. By preheating the air with the electric heating element, the air temperature increases, and its humidity capacity changes, effectively preventing condensation from occurring in subsequent equipment or pipes.

[0088] On the other hand, when the preheated air passes through the induced draft fan, its density changes due to the increased air temperature. With the internal pressure of the main pipe 123 remaining approximately constant, the increased internal temperature of the air causes it to expand in volume. Since relatively warmer air is easier to drive, the induced draft fan 126 can guide and transport the preheated air more efficiently, reducing its energy consumption.

[0089] When the electric heating element 127 is located downstream of the exhaust fan 126, the exhaust fan 126 first guides and transports the hot air from the heat exchange zone 131, forming a stable airflow within the main pipe 123. Then, the electric heating element 127 further heats the guided hot air. Based on this, the exhaust fan 126 can precisely control the flow rate and velocity of the hot air according to the drying requirements of the items in the drying space, ensuring a stable flow rate of hot air through the electric heating element 127. This is highly advantageous for precisely controlling the temperature of the heated air, as a stable airflow means that the temperature rise of the air is more predictable at a given electric heating power.

[0090] like Figure 1 As shown, in some embodiments, in order to realize the opening and closing function of the drying channel 120, a baffle 128 is provided at the air inlet 122 of the drying channel 120. The baffle 128 is used to control the opening or closing of the main pipe 123.

[0091] The baffle 128 has a heat insulation function. For example, a heat insulation layer can be provided on the front or rear side of the baffle 128, which can effectively block the transfer of heat. The heat insulation layer can be made of materials with low thermal conductivity, such as ceramic fiber or rock wool. These materials can greatly reduce the conduction of heat through the baffle. Alternatively, a heat insulation coating can be applied to the front or rear side of the baffle 128. The heat insulation coating can reflect or absorb heat, thereby reducing the heat transfer on the surface of the baffle 128.

[0092] It should be noted that the front side of the baffle 128 refers to the side that is in direct contact with the hot air in the heat exchange zone 131.

[0093] When it is necessary to dry the items to be dried in the drying space of the storage chamber 110, the baffle 128 is opened so that the baffle 128 is in the open state. The hot air in the heat exchange area 131 enters the storage chamber 110 through the drying channel 120 under the action of the induced draft fan 126, so as to dry the items to be dried in the drying space of the storage chamber 110.

[0094] When drying is not performed, the control baffle 128 is closed, allowing hot air from the heat exchange zone 131 to enter the storage chamber 110.

[0095] like Figure 1 As shown, in some embodiments, the heat exchanger 130 includes a heat exchanger 132 and an insulation element 133.

[0096] The heat exchanger 132 surrounds the heat-generating components of the RV 10. The heat-generating components of the RV 10 are used to provide a smoke exhaust duct for the high-temperature flue gas generated by the stove during cooking. In other words, the heat exchanger 132 surrounds the smoke exhaust duct, that is, the heat exchanger 132 is directly mounted on the smoke exhaust duct.

[0097] The heat exchanger 132 may include, but is not limited to, a plate heat exchanger or a shell-and-tube heat exchanger. Regardless of the type of heat exchanger used, the heat exchanger 132 can achieve efficient heat exchange, thereby absorbing the heat in the high-temperature flue gas and dissipating it into the heat exchange area 131.

[0098] When cooking is required, high-temperature flue gas will circulate in the exhaust duct. Through the heat exchanger 132, the high-temperature flue gas is cooled down and discharged outside the RV 10. After heat exchange, the hot air is guided by the induced draft fan 126 and enters the drying space through the first branch pipe 124 and the second branch pipe 126 at different air intake angles, and quickly dries the items to be dried in the drying space.

[0099] The insulation component 133 can be made of low thermal conductivity materials, such as glass wool combined with sheet metal, polyurethane foam, etc. Multiple temperature sensors can also be installed on the insulation board to monitor the temperature in the heat exchange area 131 in real time.

[0100] Multiple insulation panels are spaced around the heat exchanger 132 and wrap around all sides of the heat exchanger 132. This ensures that the insulation components 133 do not affect the normal heat exchange function of the heat exchanger 132, and works together with the heat exchanger 132 to form a relatively closed heat exchange area 131. This effectively reduces heat loss in the heat exchange area 131, reduces energy waste, and makes the RV 10 more energy efficient.

[0101] like Figure 1 As shown, in some embodiments, the heat-generating components of the RV 10 may include a smoke exhaust duct 11 for discharging high-temperature flue gas generated when the stove is in use.

[0102] The heat exchanger 132 is installed on the exhaust duct 11 to heat the air entering the drying duct 120 through heat exchange between the heat exchanger 132 and the high-temperature flue gas in the exhaust duct 11.

[0103] like Figure 1 As shown, an exemplary embodiment of the present invention also provides a motorhome 10. The motorhome 10 includes a stove 12, a smoke exhaust duct 11 for high-temperature flue gas emission, and a vehicle-mounted drying device 100 as described in any of the above embodiments.

[0104] The stove 12 is installed inside the RV 10. The exhaust duct 11 is located above the stove 12 and is used to exhaust the high-temperature flue gas generated when the stove 12 is in use.

[0105] The heat exchanger 130 in the vehicle-mounted drying device 100 is mounted on the exhaust duct 11.

[0106] The stove 12 includes a stove 12a and an exhaust fan 12b. The exhaust duct 11 includes a fume hood 111 and an exhaust pipe 112 that are interconnected, and a heat exchanger 132 is fitted onto the exhaust pipe 112.

[0107] The fume hood 111 is located directly above the stove 12a, and the exhaust fan 12b is located inside the fume hood 111. The exhaust fan 12b is used to guide the high-temperature flue gas generated when the stove 12a is in use to the exhaust pipe 112.

[0108] In this example, the vehicle-mounted drying device 100 includes a storage chamber 110, a drying channel 120 with an opening and closing function, and a heat exchanger 130. The storage chamber 110 is internally configured as a drying space for accommodating items to be dried. The air outlet 121 of the drying channel 120 communicates with the drying space in the storage chamber 110. The heat exchanger 132 in the heat exchanger 130 surrounds the exhaust channel 11 in the RV 10 and, together with the insulation component 133, forms a heat exchange area 131. The air outlet of the heat exchange area 131 is connected to the air inlet of the drying channel 120. The heat exchange area 131 is used to exchange heat with the heat-generating components of the RV 10. The heat-generating components can be the high-temperature flue gas generated when cooking in the RV. The high-temperature flue gas is used to heat the air in the heat exchange area 131. The heated air enters the drying space of the storage chamber 110 through the drying channel 120 to quickly dry the items to be dried. At the same time, it will not have any impact on the living environment inside the RV, and can effectively improve the user's experience of using the RV.

[0109] In some embodiments, when the stove 12a is turned on, the exhaust fan 12b is also turned on simultaneously. At this time, the baffle 132 is in a closed state, causing the temperature in the heat exchange zone 131 to rise rapidly to the first temperature T1.

[0110] When the temperature in the heat exchange zone 131 rises to the first temperature T1, the control baffle 132 and the induced draft fan 126 open simultaneously to dry the items to be dried in the drying space of the storage chamber 110.

[0111] During the drying process of the items to be dried, the second temperature T2 in the drying space is monitored in real time.

[0112] When the temperature difference between the first temperature T1 in the heat exchange zone 131 and the second temperature T2 in the drying space tends to stabilize and is less than or equal to the set difference T3, it can be determined that the drying process in the drying space is in the final stage of drying and that the items to be dried in the drying space have basically been dried.

[0113] Then, the induced draft fan 126 is controlled and turned off, but the control baffle 132 is turned off after a set time t1. At this time, the residual heat in the heat exchange area 131 can still enter the drying space, and finally the drying stops.

[0114] In this example RV, the heat from the high-temperature flue gas generated during cooking is collected and transferred to the air in the drying channel 120 through the heat exchange function of the heat exchanger 130, thereby heating the air in the drying channel 120.

[0115] Guided by the air intake 126, the heated air enters the drying space of the storage chamber 110 through the first branch pipe 124 and the second branch pipe 125. The hot air transported by the first branch pipe 124 enters the drying space horizontally, with the first branch pipe 124 flush with the main pipe 123. The hot air transported by the second branch pipe 125 enters the drying space vertically upward. This allows the two streams of hot air entering the drying space to converge at the location where the items to be dried are placed. The converging airflows also increase the wind disturbance effect on the fabric, thereby effectively ensuring the drying efficiency of the items to be dried. Throughout the drying process, heat is effectively collected and transferred, providing a reliable heat source for the items to be dried in the storage chamber 110 and effectively improving energy utilization.
