[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0029] Example:

[0030] like Figures 1-4 As shown, the thermal storage type off-peak power bank includes a main shell 1, a heating module 2, a thermal storage module 3, and a control module 4;

[0031] Heating module 2 and heat storage module 3 are respectively arranged in different areas inside the main shell 1. Heating module 2 is used to heat using off-peak electricity, and heat storage module 3 is used to store the heat of heating module 2. Correspondingly, the main shell 1 is provided with an air outlet 5 for releasing heat to the outside.

[0032] Control module 4 is used to control the operation of the thermal storage type power bank.

[0033] In the described energy storage-type off-peak electricity power supply, the heating module 2 heats the electricity via electricity, prioritizing operation during off-peak hours to generate heat using inexpensive off-peak electricity. The heat generated by the heating module 2 is used to heat the heat storage module 3; in other words, the heat is stored through the heat storage module 3. During peak electricity consumption periods, the heat storage module 3 releases the stored heat, which flows out of the main casing 1 through the air outlet 5 and heats the surrounding environment, meeting the user's heating needs while reducing electricity consumption and burden during peak hours. Based on this, it solves the problem of existing air conditioning systems not being able to rationally utilize off-peak electricity prices, saving users electricity bills and improving energy efficiency.

[0034] It is worth noting that by controlling the automatic operation of each module in the thermal storage power bank through the control module 4, the intelligence and automation of the thermal storage power bank are improved. The heating and heat release parameters such as temperature and time can be set according to user needs, and the energy storage status of the thermal storage module 3 can be monitored in real time to ensure the efficient operation of the thermal storage power bank and help improve the user experience.

[0035] As is easily understood, the control module 4 can be any suitable existing model, offering a wide range of choices and good practicality. Furthermore, the main housing 1 is equipped with a control switch 14, allowing the user to control the start and stop of the thermal storage-type off-peak power supply via the control switch 14.

[0036] During operation, the thermal storage power bank has an energy storage mode and an energy release mode. During off-peak hours such as nighttime, the power bank operates in energy storage mode, where the heating module 2 uses off-peak electricity to generate heat and heat the thermal storage module 3, which then stores the heat. During peak hours such as daytime, the power bank operates in energy release mode, where the thermal storage module 3 releases heat to the outside through the air outlet 5 to meet the user's heating needs.

[0037] In addition, the aforementioned thermal energy storage power bank can also utilize clean energy sources (such as photovoltaic power generation and wind power generation), effectively expanding the energy supply sources and broadening its application scope.

[0038] In summary, the aforementioned thermal storage off-peak electricity power supply is a device that uses low-priced off-peak electricity to generate and store heat, and releases heat for heating during non-off-peak hours. It can effectively reduce heating costs and significantly save on electricity bills.

[0039] In one possible implementation, the main housing 1 is provided with an installation cavity and a partition, the partition separating the installation cavity into an upper cavity and a lower cavity, the lower cavity is provided with a heat release fan 6 for releasing heat to the outside, and correspondingly, the heating module 2 and the heat storage module 3 are respectively arranged in different areas of the upper cavity, and the control module 4 is arranged on the lower cavity.

[0040] The upper cavity is provided with a return air inlet 7, and the lower cavity is provided with an air outlet 5. A connecting port is provided between the main shell 1 and the partition to connect the return air inlet 7 and the air outlet 5 and form an air duct. The heat storage module 3 and the heat release fan 6 are both located on the air duct.

[0041] Based on the above design, a partition is used to separate the heating module 2 from the equipment in the lower cavity, preventing the heat generated by the heating module 2 from affecting the equipment and ensuring its service life. This also allows the heat generated by the heating module 2 to be absorbed by the heat storage module 3 as much as possible, improving heat utilization. Furthermore, in energy storage mode, the control module 4 is used to detect the amount of heat stored in the heat storage module 3. When the amount of heat stored in the heat storage module 3 reaches a preset value, the control module 4 controls the heating module 2 to stop heating, completing the heat storage process.

[0042] In energy release mode, the heat release fan 6 is used to improve the efficiency of heat release, allowing the user's perceived temperature to rise quickly to their desired level. Accordingly, the heat release fan 6 is connected to and interfacing with the heat storage module 3 to ensure that hot air can smoothly pass through the air outlet 5 and be directed to the user. Furthermore, the return air vent 7 can draw in cool air from the user's location, forming a closed-loop "heat release-return air" cycle, which helps reduce energy loss.

[0043] As is easily understood, the heat release fan 6 is electrically connected to the control module 4 so that the operation of the heat release fan 6 can be controlled by the control module 4.

[0044] Optionally, the main housing 1 is nested with an insulated box 8 for forming a double insulation structure, and the main housing 1 is detachably provided with a back plate 9 facing the heating module 2 and the heat storage module 3; the main housing 1 is provided with rollers 10 at the bottom.

[0045] Based on the above design, the heat exchange between the main shell 1 and the outside environment is reduced by the insulated box 8, thus reducing the dissipation of heat from the heating module 2 and minimizing energy loss. The back panel 9 is detachable, facilitating the installation, disassembly, and maintenance of the heating module 2 and / or the heat storage module 3, improving the convenience of the workers. The casters 10 enhance the ease of movement of the heat storage power bank, allowing it to be moved to the desired location; correspondingly, any suitable existing model of casters 10 can be selected.

[0046] Optionally, the return air vent 7 is located at the top of the upper cavity, and a return air duct and a first filter screen are connected to the return air vent 7; a second filter screen is provided on the air outlet 5.

[0047] Based on the above design, the return air vent 7 is located at the top and the air outlet vent 5 at the bottom. Utilizing the characteristic of hot air rising helps optimize air circulation efficiency. At the same time, the return air vent 7 is located at the top of the upper cavity, achieving a concealed design that saves space and improves aesthetics.

[0048] The return air vent 7 guides the airflow through the return air duct, and the air is filtered by the first filter to minimize the intrusion of impurities. Similarly, the air outlet 5 is equipped with a second filter that also serves a filtering function. Furthermore, any suitable existing model can be selected for both the first and second filters.

[0049] In one possible implementation, a humidification module, offset from the heat-releasing fan 6, is located inside the lower cavity, and the output of the humidification module is connected to the air outlet 5. Based on the above design, water mist is delivered to the user through the humidification module to maintain a suitable indoor humidity and improve user comfort.

[0050] Optionally, the humidification module includes a water tank 11, a water mist generator 12, and a disinfection lamp 13; the water tank 11 is disposed on the lower cavity; the water mist generator 12 is disposed in the lower cavity and is used to connect the water tank 11 and the air outlet 5; the disinfection lamp 13 is disposed in the lower cavity, and the working end of the disinfection lamp 13 is connected to the water tank 11 and the water mist generator 12.

[0051] Based on the above design, the water tank 11 contains a certain amount of water. The water mist generator 12 draws in water and generates water mist. Since the water mist generator 12 is connected to the air outlet 5, the water mist is transported to the user along with the hot air. When the water mist generator 12 is working, the disinfection lamp 13 is activated and sterilizes the water source in the water tank 11 and the water mist during the transportation process, ensuring the safety and cleanliness of the humidification module.

[0052] It is easy to understand that the water mist generator 12 can be a plasma water mist generator or any other suitable existing model; similarly, the disinfection lamp 13 can be an ultraviolet disinfection lamp or any other suitable existing model.

[0053] Optionally, a portion of the water storage tank 11 extends outside the main housing 1. Therefore, the portion of the water storage tank 11 extending outside the main housing 1 can be used as an indicator to facilitate quick identification of the orientation of the thermal storage power bank by staff.

[0054] Accordingly, the water tank 11 can be connected to other components in the humidification module by any suitable existing detachable connection method, and the present invention does not impose any restrictions on this.

[0055] In one possible implementation, heating module 2 is selected as a graphene heater. Based on this, graphene heaters possess the characteristics of high thermal conductivity, rapid heating, uniform heating, good safety, long service life, and low maintenance costs, achieving heating functionality while also considering safety and economic efficiency. Alternatively, heating module 2 can also be selected from any other suitable existing models.

[0056] In one possible implementation, multiple thermal storage modules 3 are arranged at intervals, with heat release ducts forming between adjacent thermal storage modules 3. Based on this, heat release ducts are formed through the gaps between two adjacent thermal storage modules 3, providing a channel for heat transfer and thus improving the heat exchange efficiency of the thermal storage modules 3.

[0057] In one possible design, thermal storage module 3 is selected as a PCM thermal storage module. Based on this, PCM (Phase Change Material) material has high energy storage density and a stable phase change temperature, enabling efficient storage and release of energy. As easily understood, a PCM thermal storage module includes a shell and the phase change material. The phase change material is fixed in the shell by a support structure of any suitable type, ensuring that the phase change material effectively performs its cold and heat storage operations.

It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
