Description

Technical Field

[0001] This invention relates to the field of thermal energy conversion technology, and in particular to a steam heat pump heating device for outdoor travel. Background Technology

[0002] A steam heat pump is an energy-saving device that uses the principle of heat pumps to produce steam. It uses electric power to convert low-grade heat energy into high-grade heat energy, and has significant advantages in industrial heating, waste heat recovery and other fields.

[0003] Traditional steam heat pumps are bulky and inconvenient to carry outdoors. Existing outdoor heating devices either rely on fuel for heating, posing safety hazards and making fuel inconvenient to carry, or rely on pure electric heating, which has high energy consumption and short battery life. They cannot simultaneously meet the needs of heating and steam supply (cooking / sterilization).

[0004] Therefore, we propose a steam heat pump heating device for outdoor travel to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a steam heat pump heating device for outdoor travel, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An outdoor travel steam heat pump heating device includes a housing, a heat pump circulation system, and a steam generating module. The heat pump circulation system includes an evaporator, a compressor, a condenser, and an expansion valve connected in sequence. The evaporator is installed at the air inlet grille of the housing. The steam generating module includes a water tank with a heating pipe and a steam valve installed on the water tank. The water tank and the condenser are installed on the same wall. A lithium battery pack is also installed inside the housing, and a handle is provided on the housing.

[0008] In a further embodiment, a heat insulation layer is provided between the heating tube and the lithium battery pack.

[0009] In a further embodiment, a magnetic dust filter is installed outside the air intake grille of the housing via magnetic blocks.

[0010] In a further embodiment, casters are installed at all four corners of the bottom of the housing.

[0011] In a further embodiment, a charging interface and a USB interface are provided on the outer side of the housing corresponding to the lithium battery pack.

[0012] In a further embodiment, the housing is symmetrically hinged with extension platforms on both sides, and each extension platform has a pair of support rods hinged to its inner side.

[0013] In a further embodiment, the support rod consists of a threaded sleeve and a core rod, and an anti-slip pad is installed at the end of the core rod away from the sleeve.

[0014] In a further embodiment, the extended platform has a guide groove inside, a cover plate is slidably connected to the outside of the guide groove, and a solar panel is embedded in the inner surface of the guide groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention integrates a heat pump circulation system and a steam generation module into a small housing, greatly reducing the size of the entire device and improving its portability. The heat pump circulation system inside the device uses air heat energy for heating, with a significantly higher energy efficiency ratio than pure resistance heating. The condenser and water tank share the same wall design, allowing the waste heat from the heat pump to directly heat the water tank, greatly reducing the energy consumption for steam generation, extending the battery life of the lithium battery pack, and solving the problem of outdoor power shortages. The whole device has the dual functions of heating and steam supply. Attached Figure Description

[0025] Please see Figure 1-4 An outdoor travel-use steam heat pump heating device includes a housing 1, a heat pump circulation system, and a steam generating module. The housing 1 has a handle in the upper middle section and casters 13 at the four corners of the bottom for easy movement on flat ground, enhancing portability. The heat pump circulation system is installed on the left side inside the housing 1, while the steam generating module is installed on the right side. The heat pump circulation system includes an evaporator 5, a compressor 6, a condenser 7, and an expansion valve 8 connected in sequence. The evaporator 5 is embedded in the air inlet grille of the housing 1 to absorb outdoor air heat. A magnetic dust filter is installed outside the air inlet grille via magnetic blocks 12. 11. Cover the air intake grille to prevent dust; the compressor 6 compresses the low-temperature refrigerant into a high-temperature gas; the high-temperature refrigerant enters the condenser 7 to release heat and liquefy, and the heat is transferred to the water tank 2 through the common wall; after the expansion valve 8 reduces the pressure, the refrigerant returns to the evaporator 5. The steam generation module includes a water tank 2 with a heating tube 3. The heating tube 3 is installed in a disc shape at the bottom of the water tank 2. A steam valve 4 is installed on the top of the water tank 2. The steam valve 4 extends out of the top of the shell 1. The water tank 2 and the condenser 7 are installed on the same wall. The heat is transferred to the water tank 2 through the common wall. The heating tube 3 built into the water tank 2 assists in rapid vaporization. The steam valve 4 controls the steam output.

[0026] A lithium battery pack 9 is also installed inside the housing 1. The lithium battery pack 9 is installed below the heat pump circulation system and is powered by the lithium battery pack 9. A charging interface 14 and a USB interface 15 are provided on the outside of the housing 1 corresponding to the lithium battery pack 9. The charging interface 14 supports external power supply, and the USB interface 15 supports charging of electronic devices. The heat insulation layer 10 isolates the heating tube 3 from the lithium battery pack 9 to avoid the risk of high battery temperature.

[0027] The housing 1 has symmetrically hinged extension platforms 16 on both sides. Each extension platform 16 has a pair of support rods 17 hinged to its inner side. The support rods 17 are composed of a threaded sleeve 171 and a core rod 172. The end of the core rod 172 away from the sleeve 171 is equipped with an anti-slip pad 173. When the extension platform 16 is unfolded, an outdoor operating surface is provided. The length of the support rods 17 is adjusted, and the anti-slip pad 173 is fixed to the ground to adapt to uneven ground. The cover plate 18 on the guide groove of the extension platform 16 is slid to expose the solar panel 19 to generate electricity. The electrical energy is stored in the lithium battery pack 9 through the controller to further extend the range.

[0028] Workflow: Powered by lithium battery pack 9, compressor 6 is started to drive heat pump circulation. Air flows in from the air inlet grille, evaporator 5 absorbs low-grade heat energy from the air, refrigerant vaporizes, compressor 6 compresses and heats the refrigerant, and sends it to condenser 7 to release high-temperature heat. The heat from condenser 7 is conducted to water tank 2 through the common wall, heating pipe 3 assists in heating the water, steam valve 4 outputs steam as needed. While condenser 7 releases heat, it can also heat the inside of the casing 1. The extension platform 16 is unfolded, and the sliding cover 18 exposes the solar panel 19 to generate electricity and replenish the lithium battery power.
