[0001] The present invention relates to the technical field of parking heaters, and particularly to an outdoor multi-functional parking heater system. Background Art

[0002] As a traditional heating device, a diesel heater provides necessary warm air function for users in outdoor environments. However, the existing diesel heater technology has certain limitations in terms of applicability in extreme weather conditions, energy utilization efficiency, and functional diversity. In extremely cold conditions, the diesel heater may not work properly due to diesel waxing, which limits its reliability in low-temperature environments. At the same time, the high-temperature exhaust gas generated during the operation of the diesel heater is usually not effectively recovered, resulting in energy waste and environmental pollution. Although there is a certain potential for recovering the heat energy in the exhaust gas, the existing technology has not achieved 100% effective utilization of the exhaust gas heat energy.

[0003] In addition, the design of existing diesel heaters often focuses on a single warm air function and lacks the expansion of functions such as hot water supply, heating of water blankets, cooking, etc. This functional singularity limits the practicality of diesel heaters in outdoor activities and cannot meet the various needs of users for heating, hot water, cooking, etc.

[0004] Therefore, in order to overcome the deficiencies of the existing technology, an improved diesel heater technology is needed, which can operate stably in extremely cold conditions, effectively recover and utilize the heat energy of the exhaust gas emissions, and provide more function expansions to improve the comfort and convenience of outdoor activities.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0043] Embodiment 1

[0044] Referring to Figure 1-11 For an embodiment of the present invention, it discloses an outdoor multi-functional parking heater system, which specifically includes a heating unit 1 and an expansion unit 2 connected by pipelines; wherein, the heating unit 1 includes a housing 11, and a water tank assembly 12, a fuel tank assembly 13 and a heating assembly 14 are installed in the housing 11, and a heat exchange device 15 is also fixed inside the housing 11;

[0045] The heating assembly 14 exchanges heat with the heat exchange device 15, and the water outlet end of the water tank assembly 12 is heated and raised in temperature through the heat exchange device 15.

[0046] Certainly, in the present invention, a controller is also provided for realizing the start-stop control of each electrical component. Preferably, the controller is arranged inside the housing 11 and covered with a maintenance cover, and the overall structure is rainproof and dustproof. At the same time, due to the high temperature inside the machine, the use stability of the liquid crystal screen of the controller in a low-temperature environment is ensured.

[0047] In addition, in the embodiments of the present invention, a drainage groove is provided at the bottom of the housing 11. The purpose is that in case of special circumstances where water enters the interior of the chassis, it can quickly drain water. This is also required for the internal and external temperature balance. When the machine is working, the heat inside the chassis will accumulate and increase, and this can also discharge some heat, so that the interior of the chassis will not overheat.

[0048] Referring to Figure 1 , in some embodiments, the expansion unit 2 in the present invention includes one or more combinations of a hydrothermal air conditioner 21, a water heating blanket 22, a water pool 23, a stove 24, and a vehicle-mounted window air conditioner 26. Specifically, the hydrothermal air conditioner 21 and the water heating blanket 22 are both existing technologies and will not be elaborated here. The hydrothermal air conditioner 21 uses water circulation to adjust the indoor temperature. Specifically, it uses fins to exchange heat with the circulating water pipe and blows out the heat through a fan. It is more energy-saving and environmentally friendly than traditional air conditioning systems. The water heating blanket 22 provides a new heating method, heating the blanket through hot water circulation, which is both comfortable and energy-saving. The water pool 23 can directly heat the water to meet the hot water demand functions such as outdoor bathing. That is, in this system, through the expansion of functions such as hot water, water heating blanket, and cooking, the recovery and utilization of tail gas emissions can be realized.

[0049] As Figure 13 shown, in this embodiment, the vehicle-mounted window air conditioner 26 includes a hanging plate, a ventilation fan 262 and a heat exchanger 261 installed on the hanging plate. The hanging plate is connected to the car window for fixation. Two water pipe holes and an outlet hole are opened on the hanging plate. During specific installation, the in-vehicle power cord can be led out along the outlet hole and electrically connected to the device. Then, the two water pipes of the heat exchange device 15 enter through the two water pipe holes and are connected to the heat exchanger 261. The heat exchanger 261 evenly transfers the heat in the hot water pipe with the help of fins and blows it out by the fan to heat the interior of the vehicle.

[0050] Furthermore, in this embodiment, the heating component 14 is a warm air heater. The specific structure and working principle of the warm air heater have been publicly disclosed in the prior art, so no further elaboration will be provided;

[0051] Referring to Figure 2 , 3 , specifically, in this embodiment, an air inlet 111 and an air outlet 112 for the warm air heater to intake and exhaust air are respectively opened on the outer side of the housing 11. A combustion air pipe 113 connected to the warm air heater is also provided on the outer side of the housing 11. The exhaust port 114 of the warm air heater is communicated with the heat exchange device 15.

[0052] Referring to Figure 4, on the basis of the above embodiments, in the heat exchange device 15 of the embodiments of the present invention, the heat exchange device 15 includes a heat exchange box 151. Inside the heat exchange box 151, two stacked and interconnected annular pipes 152 are fixedly installed. The two annular pipes 152 are used for the water in the water supply tank 121 to flow, so as to achieve heat exchange and temperature rise. Heat exchange fins 153 are fixedly extended to the outside in the annular pipes 152. Specifically, when the high-temperature exhaust gas is discharged from the exhaust port 114 of the air heater, the exhaust gas exchanges heat through the heat exchange fins 153 to achieve temperature reduction, and the heat exchange fins 153 can heat the water in the annular pipes 152 to complete the temperature rise of the water in the annular pipes 152;

[0053] Refer to Figure 4 , 5 , 10, wherein, a heat conduction pipe 154 is also fixedly installed inside the heat exchange box 151. Preferably, the heat conduction pipe 154 in this embodiment is a square pipe. One end of the heat conduction pipe 154 penetrates through the heat exchange box 151 and extends to the outside of the housing 11. The upper end of the heat conduction pipe 154 is communicated with the exhaust port 114 of the air heater, and an exhaust gap 155 is opened on its bottom end surface. A tail gas hole 156 communicating to the outside of the housing 11 is also fixedly installed on the heat exchange box 151. The tail gas hole 156 is arranged as a round pipe, which is used to discharge the heat-exchanged tail gas. Specifically, in the embodiments of the present invention, a muffler 245 can be inserted inside the tail gas hole 156. The muffler 245 is a common noise reduction device, which reduces the noise generated when the air flow passes through through the design of its internal structure. Inserting the muffler 245 inside the tail gas hole 156 can effectively reduce the noise level during tail gas emission, make the operation of the whole system quieter, and also meet the requirements of environmental protection and noise reduction.

[0054] Refer to Figure 5 , further, cover plates 157 can be fixedly connected to the outer ends of the heat conduction pipe 154 and the tail gas hole 156 in this embodiment. Among them, one side of the cover plate 157 is rotatably connected to the top of the housing 11, and the other side is detachably screwed to the heat exchange box 151, which is convenient for the later maintenance, repair or replacement of the heat exchanger. Specifically, two heat exchange fins 153 are provided in this embodiment, and six-layer serpentine exhaust pipes are configured to absorb all the effective heat energy of the tail gas and improve the heat exchange efficiency.

[0055] Refer to Figure 2, on the basis of the above embodiments, in the embodiments of the present invention, the water tank assembly 12 includes a water tank 121 and a water pump 122. The water tank 121 is communicated with one of the annular pipes 152 through a water pipe, a water pump 122 and a joint 123. An outlet pipe 124 is connected to the other annular pipe 152 through a joint 123. The outlet pipe 124 is connected to the expansion unit 2, and the return pipe 125 of the expansion unit 2 is connected to the water tank 121 to achieve pipeline connection.

[0056] Of course, in this embodiment, the fuel tank assembly 13 includes a fuel tank and an oil pump. Both the fuel tank and the water tank 121 are integrally welded with all-aluminum alloy, ensuring the thermal conductivity of both. When the machine is running, the water tank 121 is at a high temperature, so the fuel tank is always in a warm state. Therefore, the problem of waxing of diesel oil at extremely cold low temperatures and the machine stopping working will not occur. The water tank and the fuel tank are treated with all-aluminum alloy spray painting technology, ensuring complete airtightness and no air leakage.

[0057] Among them, the one-way exhaust valve is on the water tank 121 in the present invention. After the lid is tightened, negative pressure can be used to absorb water, which can realize the heating of the water pool 23, achieving the separation of water and electricity. It is a fully enclosed negative pressure self-priming circulation system. The transmission and release of heat energy are both completed by water. The heat-insulating sleeve of the water pipe with extremely low heat loss ensures the long-distance transmission of heat energy.

[0058] The two-way breather valve on the fuel tank is oil-resistant. It can only allow air to pass through and diesel oil cannot come out. In this way, even if the fuel tank is tilted or inverted, no oil will leak, truly achieving no oil leakage and no diesel smell.

[0059] When used outdoors, without starting the heating component 14, if there is a cold source such as mountain spring water nearby, or relatively cold river water or deep water, and the water temperature in the deep water area is relatively low and the water quality is good, the function of an air-cooled air conditioner can be realized by using the external circulation of negative pressure water absorption. In the case of poor water quality, the warm air heat exchanger can also be placed in the cold source to obtain cold water, and then the cold air can be released by using the water heat air conditioner.

[0060] That is to say, compared with the existing outdoor gas water heater products and outdoor heating equipment, the outdoor water heat circulation system provided by the present invention has significant technical advantages and a wider application scenario. The existing gas water heater products have problems such as complex operation and rough structure, and there are many potential safety hazards. The present invention uses higher-quality materials and delicate designs to ensure the safety, reliability and long-term stability of the system.

[0061] The present invention can provide the heating function for a ton - level swimming pool water by connecting to the water pool 23 and realizing circulating heating. In a high - temperature environment in summer, when the air temperature reaches 38 degrees, the normal water temperature is usually 26 degrees, which may be too cool for children to swim. Out of concern for the children, parents may not be willing to let their children swim in such water temperature. However, through the swimming pool water heating function of the present invention, parents can heat the swimming pool water temperature to 30 degrees, creating a comfortable warm - water environment for children to swim in the pool without worrying about the water temperature being too low.

[0062] The device of the present invention not only provides the hot - water function, but also integrates a warm - air system, which is applicable to outdoor showers, bathing, and more extensive uses, such as outdoor steam baths, saunas, heating of ton - level swimming pool water, and even can be used for heating artificial hot springs in the wild. Different from gas water heaters, the present invention is applicable to various complex weather conditions, including rain, snow, sand and wind, etc., realizing a multi - functional outdoor heat - energy solution that can be used throughout the four seasons.

[0063] Especially in an environment with a relatively low temperature, the present invention provides a more comfortable and healthy bathing experience. Users can pre - heat the bathroom air through the warm - air system before bathing, creating a warm environment while enjoying hot - water bathing. After bathing, the warm - air system can also be used to dry the body, hair, clothes, towels, etc., providing all - round warmth and convenience.

[0064] In summary, the outdoor water - heat circulation system provided by the present invention is significantly superior to the existing outdoor gas water - heater products and outdoor heating equipment in terms of functional diversity, safety and reliability, material quality, applicability, etc., representing the technological progress in the field of outdoor heat - energy equipment.

[0065] Refer to Figure 1 , it should be noted that in the embodiment of the present invention, the air outlet 112 pipeline of the warm - air heater is connected to the warm - air heat exchanger 25, and the exhaust end of the warm - air heat exchanger 25 is connected to the air inlet 111 of the warm - air heater through a pipeline to realize hot - air circulation. The exhaust end of the warm - air heat exchanger 25 is connected to the air inlet 111 of the warm - air heater through a pipeline, forming a hot - air circulation system. Such a circulation design can effectively utilize the heat energy in the hot air, avoid energy waste, and can continuously provide a warm ambient temperature;

[0066] Among them, the water outlet pipe 124 of the water tank assembly 12 is secondarily heated through the warm - air heat exchanger 25, and the water - heat air conditioner 21 and the water - heating blanket 22 are both connected to the water outlet pipe 124 of the water tank assembly 12 to form a return water pipe 125.

[0067] That is, in the embodiment of the present invention, the warm air heat exchanger 25 is provided to perform secondary heating on the water in the water outlet pipe 124. After the water outlet pipe 124 of the water tank assembly 12 is subjected to secondary heating through the warm air heat exchanger 25, the water temperature is further increased. This structure effectively utilizes the hot air generated by the warm air heater 25, realizes the secondary heating of water, improves the utilization efficiency of thermal energy, and provides multiple warm solutions for the indoor environment. This design is not only energy-saving and efficient but also provides a comfortable experience.

[0068] Referring to Figure 6-8 , in a preferred embodiment, the stove 24 in the present invention includes a stove body 241 and a cooking utensil 242. Among them, a transfer pipe 16 is connected between the stove body 241 and the heat conduction pipe 154. Specifically, the cooking utensil 242 in this embodiment can be set as a cooking pot or a fish baking tray, with multiple cooking methods available, improving the convenience and applicability of use;

[0069] Referring to Figure 7 , a partition 246 is fixed inside the stove body 241. An air delivery pipe 243 is fixedly installed outside the stove body 241. The air delivery pipe 243 is connected to the transfer pipe 16. The air delivery pipe 243 communicates to the partition 246. A number of air return holes 247 are also opened on the end face of the partition 246. A discharge pipe 244 communicating between the partition 246 and the stove body 241 is fixed outside the stove body 241. A silencer 245 is detachably connected to the discharge pipe 244.

[0070] Referring to Figure 6 , specifically, in the present invention, the transfer pipe 16 is used to connect the heat conduction pipe 154, which can realize guiding all the high-temperature exhaust gas discharged from the exhaust port 114 of the warm air heater to the stove body 241 to achieve flameless high-temperature heating. It should be noted that in the present invention, high-temperature gas is introduced through the air delivery pipe 243. After the high-temperature gas heats the cooking utensil 242, the cooled exhaust gas enters below the partition 246 along the air return holes 247 and is discharged outward through the discharge pipe 244. This design can ensure the separation of the two paths of gas, avoid interference between the high-temperature gas and the relatively low-temperature gas after heating, and ensure the heating stability of the cooking utensil 242.

[0071] At present, mainstream outdoor flameless cooking technologies include electric heating, solar stoves and self-heating stoves, but these technologies have their own disadvantages, such as high energy consumption, weather dependence or safety hazards. In contrast, our flameless outdoor cooking stoves are made of all 304 stainless steel, which is durable and has low power consumption. They use exhaust heat for cooking, and can also realize hot water backup and heating. They are suitable for forest fire prevention periods, meet a variety of cooking needs, and can be converted to other modes after the end. The specific switching method will be described in detail later, so I won’t go into details here. It is an ideal choice for traceless camping and the best flameless outdoor cooking solution.

[0072] It should be noted that, in the embodiment of the present invention, a limiting tube 161 is fixed on the outer side of the adapter tube 16, and the limiting tube 161 limits the maximum plug-in position of the adapter tube 16. A adapter notch 162 is opened above the end of the adapter tube 16. When one end of the adapter tube 16 is plugged into the heat transfer tube 154, the adapter notch 162 is used to lead out the high-temperature gas in the exhaust port 114 of the air heater.

[0073] Reference Figure 9 , 10 On the basis of the above embodiment, in the present invention, a plurality of positioning holes 163 are provided inside the heat conducting pipe 154 and the gas delivery pipe 243, a U-shaped locking rod 164 is movably inserted on the outer side of the transfer pipe 16, a pressing rod 165 fixed to the U-shaped locking rod 164 is inserted on the outer side of the limiting pipe 161, and a spring 166 is fixedly connected between the U-shaped locking rod 164 and the transfer pipe 16;

[0074] That is to say, in the present invention, the U-shaped locking rod 164 can be pressed by pressing the pressing rod 165. When the U-shaped locking rod 164 moves inward, the U-shaped locking rod 164 can be clamped with the positioning hole 163 in the heat pipe 154 and / or the gas pipe 243 to locate the clamping position of the U-shaped locking rod 164. The position-adjustable structural design can change the position of the U-shaped locking rod 164 inserted into the heat pipe 154. Such a design can achieve an air conduction ratio between the transfer notch 162 and the exhaust port 114 of the air heater.

[0075] Specifically, when the adapter tube 16 is completely inserted into the heat conducting tube 154, the stop tube 161 stops at the outside of the housing 11, and the bottom of the adapter tube 16 blocks the exhaust notch 155, so all the high-temperature exhaust gas will enter the inside of the adapter tube 16 along the adapter notch 162 to heat the pot 242;

[0076] When the adapter tube 16 is not fully inserted inside the heat conduction tube 154, at this time, a part of the high-temperature gas enters the inside of the adapter tube 16 along the adapter notch 162 to realize the heating and heat preservation modes of the cookware 242, and a part of the high-temperature exhaust gas enters the inside of the heat exchange device 15 along the exhaust notch 155 to realize the heating of water to meet the usage requirements of other expansion units 2.

[0077] Refer to Figure 10 , wherein, a push rod 167 is movably inserted inside the adapter tube 16, a stop block 168 that abuts against the push rod 167 is fixed on the inner side of the heat conduction tube 154, an indicating rod 1610 is rotatably connected to the limiting tube 161 through a shaft rod 169, and an indicating portion 1611 is arranged on the outer side of the limiting tube 161. Among them, a torsion spring 1614 is arranged between the shaft rod 169 and the adapter tube 16, and a gear 1612 is fixed at the bottom, and a rack 1613 meshing with the gear 1612 is fixed on the end surface of the push rod 167.

[0078] That is, in the present invention, a rotatable indicating rod 1610 is provided to cooperate with the indicating portion 1611 to visually display the insertion depth of the current adapter tube 16. That is, calculate the ratio according to the maximum insertion depth of the adapter tube 16, and then display it according to the indicating portion 1611. During specific operation, when the adapter tube 16 is inserted, the push rod 167 inside it will abut against the stop block 168 inside the heat conduction tube 154. In this way, the push rod 167 generates a relative displacement inside the adapter tube 16, and thus the rack 1613 outside it can mesh with the gear 1612 to rotate, so as to drive the entire shaft rod 169 to drive the indicating rod 1610 to rotate. At this time, according to the insertion depth ratio displayed by the indicating rod 1610, it is possible to control the amount of high-temperature gas discharged outside in the double-row mode.

[0079] In addition, as Figure 12 shown, in the present invention, the flameless cooking stove 241 can be turned over and used as an alcohol stove, which is suitable for non-forest fire prevention periods or household use. Multiple support claws are arranged at the bottom of the stove 241, and the support claws can support almost all household cookware, further optimizing its functionality and expanding the scope of application.

[0080] Specifically, the present invention includes the following combined usage modes of multiple modes:

[0081] The main cabinet of the air heater: It has an independently controlled main machine and a negative pressure self-absorbing water circulation system, which can be used for car washing, vegetable washing, etc. when the diesel heater equipment is not started. After starting, it uses the heat energy of the diesel heater exhaust gas to heat water, and after turning off the diesel heater, the system provides constant temperature bathing water.

[0082] Air heater main unit + Warm air heat exchanger: These two combinations achieve outdoor heating and hot water freedom. The system is safe, interesting, suitable for children, and has diverse functions, including showering, bathing, sauna, steam bath, and pool water heating, even artificial hot springs in the wild. Since the air heater main unit has slow hot water, it can heat the water heating blanket. Heating a small amount of water for a long time can obtain hot water. Only when the air heater main unit and the warm air heat exchanger are combined together can the function of heating tons of water be achieved;

[0083] Air heater main unit + Water heat air conditioner: Effectively manage heat energy. The water heat air conditioner can convert the excessive heat of the water heating blanket into warm air, both cooling the water heating blanket and raising the indoor temperature. Users can adjust it remotely to ensure comfort;

[0084] Air heater main unit + Warm air heat exchanger + Flameless cooking stove: This system can achieve flameless hot water freedom, flameless cooking, and flameless outdoor heating. By using them together, the maximum utilization rate of the heat energy released by the air heater can be exerted;

[0085] Air heater main unit + Warm air heat exchanger + Water heat air conditioner: Suitable for camping environments with women or children. In addition, in the present invention, through a tee, operations such as splitting one air duct or water pipe into two or three can be realized, increasing the area of the water heating blanket or heating two or more tents simultaneously.

[0086] Embodiment 2

[0087] Refer to Figure 14-15 , specifically, in this embodiment, the same parts as those in Embodiment 1 will not be elaborated again. The differences are as follows:

[0088] In this embodiment, the heating component 14 is a water heater. Of course, the water heater is also prior art and will not be elaborated here. It works by connecting to the fuel tank component 13, and its water tank component 12 is heated by the water heater;

[0089] The water heat efficiency of the water heater main unit box is 2 - 3 times that of the air heater main unit. For the water heat air conditioning heating system of the air heater main unit, it is necessary to convert the warm air into water heat, and there is a large amount of heat energy loss in the process. While the water heater itself is a water heating boiler, the internal combustion chamber burns diesel to directly heat the circulating water in the boiler, and its heat loss is extremely low. The water heat air conditioning heating system of the air heater main unit can at most achieve a one-to-two split, while the water heater main unit can achieve a one-to-two split, a one-to-three split, or even a one-to-four split, etc. One machine can supply heat to multiple tents simultaneously, and the maximum inlet water temperature of each tent can be set to 90 degrees.

[0090] Wherein, a combustion air pipe 113 connected to the water heating heater is further provided on the outer side of the housing 11, an exhaust gas hole 156 is formed on the outer side of the housing 11, and an exhaust port 114 of the water heating heater is communicated with the exhaust gas hole 156.

[0091] Further, in this embodiment, the specific heating method is that the water tank assembly 12 is connected to the water heating heater through a water pump 122 and a water pipe, and after being heated by the water heating heater, it is externally discharged to connect each expansion unit 2.

[0092] It should be noted that since the water heating heater has a relatively high thermal efficiency compared to the air heating heater, its exhaust gas temperature is relatively low. In addition, in the present invention, negative pressure suction of the water tank is adopted to realize the cyclic heating of water to improve the heating efficiency. Secondly, in the case where the exhaust gas temperature of the water heating heater is relatively low in the present invention, considering that the applicable surface is small when connecting the stove 24, only one exhaust gas hole 156 is provided on the housing 11 in this embodiment. The exhaust gas hole 156 is provided as a round pipe, which is used to directly discharge the exhaust gas. Specifically, in the embodiment of the present invention, a muffler 245 can be inserted into the exhaust gas hole 156. The muffler 245 is a common noise reduction device, which reduces the noise generated when the air flow passes through by the design of its internal structure. Inserting the muffler 245 into the exhaust gas hole 156 can effectively reduce the noise level during exhaust gas emission, making the operation of the entire system quieter.

[0093] The outdoor water heat circulation system provided by the present invention is significantly superior to the existing outdoor gas water heaters and outdoor heating equipment in terms of functional diversity, safety and reliability, material quality, applicability, etc., representing the technological progress in the field of outdoor thermal energy equipment. Secondly, the whole set of equipment is of an assembled structure, and each spare part is convenient to replace, maintain and repair. It is especially developed for the forest fire prevention period, providing a flameless outdoor cooking and heating function, ensuring the safety and environmental protection during the use process. Generally speaking, this solution ensures the safety and comfort of users, while greatly improving the energy utilization efficiency, reducing the cost, and providing diversified outdoor thermal energy solutions.

[0094] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
