Description

Technical Field

[0001] This utility model relates to an electric heater. Background Technology

[0002] Currently, electric heaters on the market are mainly divided into two categories: direct-heating electric heaters and heat storage electric heaters. Direct-heating electric heaters use electric heating elements to directly heat the air or metal heat sink, and heat up quickly. However, due to the lack of heat storage capacity, the heating effect drops rapidly once the power is cut off. In addition, their continuous operation may cause large power fluctuations, affecting the stability of the power grid, and their energy utilization efficiency is low.

[0003] Thermal storage electric heaters store heat through energy storage materials (such as high-temperature ceramics, thermal storage bricks, etc.) and then slowly release the heat energy through radiation or convection, resulting in a high energy efficiency ratio. However, such devices heat up slowly and cannot provide comfortable indoor temperature regulation in a short period of time. Furthermore, existing thermal storage electric heaters are often large in size, which limits their installation and use. Utility Model Content

Detailed Implementation

[0049] Specific Implementation Method 1: Combination Figures 1 to 5 This embodiment describes an intelligent control energy storage electric heater, which includes a direct heating component 1, a heat storage component 2, and an intelligent control system.

[0050] The heat storage component 2 includes a heating rod 2-1, a heat storage body 2-2, and a heat preservation box 2-3;

[0051] The heat storage body 2-2 is placed inside the heat preservation box 2-3, and the heating rod 2-1 is inserted into the heat preservation box 2-3 from one side, passes through the heat storage body 2-2, and exits from the other side of the heat preservation box 2-3;

[0052] The intelligent control system includes a controller 15, a temperature adjustment knob 11, a switch 12, and a temperature sensor 16;

[0053] The switching switch 12 is used to input a switching command, and the switching command signal output terminal of the switching switch 12 is connected to the switching command signal input terminal of the controller 15. The controller 15 selects to connect the power supply of the direct heating component 1 or the heating rod 2-1 according to the input switching command signal.

[0054] The temperature sensor 16 is used to acquire the ambient temperature, and the temperature sensing signal output terminal of the temperature sensor 16 is connected to the temperature sensing signal input terminal of the controller 15.

[0055] The temperature adjustment knob 11 is used to input the temperature threshold, and the temperature threshold signal output terminal of the temperature adjustment knob 11 is connected to the temperature threshold signal input terminal of the controller 15.

[0056] The controller 15 compares the input temperature sensing signal with the input temperature threshold signal. When the temperature sensing signal is less than the temperature threshold signal, the controller 15 outputs an increase power control signal to the power supply. When the temperature sensing signal is greater than or equal to the temperature threshold signal, the controller 15 outputs a decrease power control signal to the power supply.

[0057] In this embodiment, the heat storage body 2-2 is made of a high-efficiency heat storage material, such as phase change energy storage material, high-density heat storage brick, special ceramic or metal heat storage body; after the power supply is turned on, when the heating rod 2-1 heats, the heat storage body 2-2 absorbs a large amount of heat energy and gradually releases heat in the power-off or low-power mode to ensure continuous heating capacity; the heat preservation box 2-3 has a heat preservation effect, which can effectively slow down the heat loss, so that the heat stored in the heat storage body 2-2 is released slowly at a certain rate; when the power supply receives the power increase control signal, the power supply will increase the current output. When the initial current output of the power supply reaches the maximum rated current, the power supply will maintain the maximum rated current output and will not continue to increase; the direct heating component 1 can provide high-power heat output in a short time to achieve rapid heating. The system rapidly raises the ambient temperature to the set threshold. The heat storage component 2 absorbs a large amount of heat energy when powered on and gradually releases it during power outages or low-power operation, ensuring continuous heating capacity. Optimized heat distribution design: Through a reasonable structural arrangement, the direct heating component 1 prioritizes providing power to the heat storage component 2, while the heat storage component 2 releases stored heat energy when the direct heating component 1 is off or operating at low power, achieving efficient thermal management. The intelligent control system precisely manages the heating process, improving energy efficiency and reducing unnecessary energy waste. Dual-mode switching: The temperature sensor 16 measures the ambient temperature outside the casing 3, and the controller 15 can switch between direct heating mode and heat storage mode based on the ambient temperature, user-set threshold temperature, and operating status. For example, when turned on, the direct heating component 1 operates first. Once the temperature reaches the set temperature threshold, the controller 15 gradually reduces the power of the direct heating component 1 and activates the heat storage and release mode to maintain a stable temperature and save energy. The controller 15 is model LY-PDWA11. The controller 15 has an intelligent energy-saving mode: it automatically adjusts the heating power based on factors such as indoor temperature and external climate conditions to reduce unnecessary energy consumption. The controller 15 also has multiple safety protection modes: including over-temperature protection, over-current protection, and tip-over power-off protection, to ensure safe operation of the equipment. Over-temperature protection: when the temperature... When the safety value is exceeded, the power supply automatically cuts off; overcurrent protection: when the current output by the power supply reaches the maximum safe current threshold, the power supply automatically cuts off to prevent short circuits or overloads. The maximum safe current threshold is greater than the maximum rated current, thereby improving equipment safety; tilting power-off protection: when the equipment tilts beyond a certain angle, the power supply automatically cuts off to prevent safety hazards; the intelligent control energy storage electric heater described in this embodiment can provide a comfortable heating effect in a short time, while also having a long-term heat storage capacity, improving energy efficiency, reducing user operating costs, and meeting the needs of modern smart homes.

[0058] Specific Implementation Method Two: This implementation method further defines the intelligent control energy storage electric heater described in Specific Implementation Method One. In this implementation method, it also includes a housing 3.

[0059] The direct heating component 1, the heat storage component 2, and the controller 15 are all housed inside the outer casing 3. The heat storage component 2 is located at the bottom of the outer casing 3, the direct heating component 1 is located on the heat storage component 2, and the controller 15 is located on the upper part of the inner wall of the outer casing 3 to avoid mutual interference between different structures.

[0060] The temperature adjustment knob 11 and the switch 12 are both located on the outer side wall of the housing 3;

[0061] The temperature sensor 16 is located inside the controller 15.

[0062] In this embodiment, the direct heating component 1, the heat storage component 2 and the control system are integrated together by the outer casing 3. The outer casing 3 protects the direct heating component 1, the heat storage component 2 and the control system, reducing the possibility of damage from external forces. At the same time, the outer casing 3 also protects the user. The outer casing 3 can effectively prevent direct contact with the high-temperature direct heating component 1 and avoid safety accidents.

[0063] Specific Implementation Method 3: This implementation method further defines the intelligent control energy storage electric heater described in Specific Implementation Method 2. In this implementation method, the outer shell 3 is a cuboid structure, and a bevel is cut between the front and top surfaces of the cuboid.

[0064] A row of direct-heating air outlets 10 are provided on the inclined surface; and a gas guide shroud 4 is provided inside the outer casing 3 at the position corresponding to the direct-heating air outlets 10.

[0065] A row of direct-heating air inlets 5 and a row of heat storage air outlets 6 are provided on the front of the outer casing 3; wherein, the direct-heating air inlets 5 are opposite to the direct-heating component 1; and the heat storage air outlets 6 are opposite to the heat storage component 2.

[0066] A row of main air inlets 13 is opened at the bottom of the outer casing 3.

[0067] In this embodiment, cold air from outside the outer casing 3 enters through the direct-heating air inlet 5, and is heated by the direct-heating heating component 1 to become hot air. The hot air then passes through the gas guide shroud 4 and the direct-heating air outlet 10 before returning to the outside of the outer casing 3, thus realizing the heating cycle of the direct-heating heating component 1. Cold air from outside the outer casing 3 enters through the main air inlet 13, and is heated by the heat storage component 21 to become hot air. The hot air then returns to the outside of the outer casing 3 through the heat storage air outlet 6, thus realizing the heating cycle of the heat storage component 2. The gas guide shroud 4 is an inclined steel plate, which forms a 90-degree angle with the aforementioned inclined surface. The gas guide shroud 4 prevents hot air from entering the dead corners of the outer casing 3, instead directly refracting the hot air to the direct-heating air outlet 10, from which it is directly discharged. The two circulation paths can be superimposed to form a special air intake structure, achieving the optimal convective heat exchange effect. To better control the air circulation effect and the heat dissipation time and speed of the heat storage component 2, a circulation fan can be installed in the air circulation passage inside the housing 3.

[0070] In this embodiment, the anti-slip mat 8 has a columnar structure, preferably a cylindrical structure, and the number of anti-slip mats 8 is three or more, preferably four. By setting the anti-slip mat 8, it is ensured that the bottom of the outer shell 3 can be in direct contact with the outside air. In addition, the anti-slip mat 8 can prevent the temperature of the outer shell 3 from becoming too high and damaging the items placed there. At the same time, the anti-slip mat 8 has an anti-slip function to prevent the outer shell 3 from moving.

[0071] Specific Implementation Method 5: This implementation method further defines the intelligent control energy storage electric heater described in Specific Implementation Method 2. In this implementation method, it also includes a handle 9.

[0072] The handle 9 is located on the left and right side walls of the outer casing 3.

[0073] In this embodiment, the handle 9 is provided to facilitate the movement of the intelligent control energy storage electric heater.

[0074] Specific Implementation Method Six: This implementation method further defines the intelligent control energy storage electric heater described in Specific Implementation Method One. In this implementation method, the direct heating component 1 is a PTC ceramic heating element, an electric heating wire, or a carbon fiber heating wire.

[0075] In this embodiment, the PTC ceramic heating element, heating wire or carbon fiber heating wire are all high-efficiency resistance heating elements. The direct heating assembly 1 is composed of multiple high-efficiency resistance heating elements arranged side by side. After the high-efficiency resistance heating element is connected to the power supply, it provides high-temperature heat in a short time, so that the user can feel the warmth immediately after turning on the electric heater.

[0076] Specific Implementation Method Seven: This implementation method further defines the intelligent control energy storage electric heater described in Specific Implementation Method One. In this implementation method, the bottom of the heat preservation box 2-3 is provided with a gas guide hole 7.

[0077] In this embodiment, the gas guide hole 7 is designed to ensure that cold air from outside the outer shell 3 can freely enter the outer shell 3 and come into full contact with the insulation box 2-3, so that the temperature of the insulation box 2-3 can freely diffuse to the outside of the outer shell 3.

[0078] Specific Implementation Method 8: This implementation method further defines the intelligent control energy storage electric heater described in Specific Implementation Method 1. In this implementation method, a bracket 14 is also included.
