Description

Technical Field

[0001] This utility model relates to the field of electric oil heater technology, and in particular to a rapid thermal radiation humidification type electric oil heater. Background Technology

[0002] An oil-filled radiator is a common household heating device. Its heating principle is as follows: the inside of the oil-filled radiator is filled with high-temperature heat-conducting oil. The oil acts as a heat carrier and is heated by the electric heating element. It then circulates naturally through convection, transferring heat to the metal heat sink and finally heating the indoor space through air convection.

[0003] Traditional oil-filled radiators generally use a mechanical temperature control structure, adjusting the heating power with a single knob to achieve temperature control. These devices suffer from poor human-machine interaction; lacking a visual display module, users cannot obtain real-time information about the current temperature, target temperature, or device operating status, leading to reliance on experience-based judgment, low adjustment accuracy, and susceptibility to errors.

[0004] Therefore, there is an urgent need to develop a new type of electric oil heater that integrates intelligent display and collaborative control, and achieves precise temperature control and airflow control through human-computer interaction optimization and mechatronics design. Utility Model Content

[0005] The purpose of this invention is to provide a fast-heating humidifying electric oil heater with optimized human-computer interaction and precise temperature control.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a rapid thermal radiation humidification type electric oil heater, comprising an electric oil heater body, an oil tank connected to one side of the electric oil heater body, an electric heating tube disposed inside the oil tank, an axial flow fan disposed inside the electric oil heater body, the axial flow fan being electrically connected to an internal controller, a display screen mounted on the other side of the electric oil heater body, a temperature control knob and a fan speed control knob disposed in the same direction below the display screen, the temperature control knob being electrically connected to the electric heating tube inside the oil tank, and the fan speed control knob being signal-coupled to the axial flow fan drive module.

[0007] By adopting the above technical solution, when the temperature control knob is turned on or off, it sends a signal to the controller. The controller then controls the electric heating element to turn on or off. When the temperature control knob changes the temperature, the user sets a target temperature, and the display shows the set target temperature value in real time. The knob sends a signal to the controller, which monitors the current temperature of the hot oil in the oil tank in real time and compares it with the set target temperature, calculating the deviation. The controller then adjusts the heating temperature by controlling the energizing time of the electric heating element based on the deviation value. Similarly, when the fan speed control knob is turned on or off, it sends a signal to the controller, which controls the axial fan motor to turn on or off. When the fan speed control knob changes the speed, the user sets a target speed, and the display shows the set target speed value in real time. The knob sends a signal to the controller, which monitors the current speed of the axial fan in real time and compares it with the set target speed, calculating the deviation. The controller then controls the motor voltage of the axial fan to change the speed based on the deviation value. The display refreshes data at a fixed frequency, forming a real-time data interface. Users can obtain real-time information on current temperature / speed, target temperature / speed, and operating status of electric heating element / axial fan, optimizing human-machine interaction and achieving precise temperature and airflow control.

[0008] A further feature of this invention is that a temperature sensor is provided on the outer wall of the main body of the electric oil heater. The temperature sensor is electrically connected to the controller inside the main body of the electric oil heater. When the temperature sensor senses that the indoor temperature reaches a preset temperature threshold, the controller controls the electric heating tube inside the oil tank to switch on and off.

[0009] By adopting the above technical solution, a temperature threshold is first preset on the controller. The temperature sensor detects the ambient temperature and outputs a signal to the controller. After receiving the temperature signal, the controller compares the temperature value read with the preset temperature threshold and calculates the deviation. The controller controls the electric heating tube to turn on and off based on the deviation value, which can reduce energy consumption and save electricity costs.

[0010] A further feature of this invention is that the main body of the electric oil heater is equipped with a humidification device and a humidity sensor that senses the outside of the main body of the electric oil heater. The humidity sensor is located on the outer wall of the main body of the electric oil heater and is electrically connected to a controller inside the main body of the electric oil heater. When the humidity sensor senses that the indoor humidity reaches a preset humidity threshold, the controller controls the axial fan and the humidification device to switch on and off.

[0011] By adopting the above technical solution, a humidity threshold is first preset on the controller. The humidity sensor detects the ambient humidity and outputs a signal to the controller. After receiving the humidity signal, the controller compares the humidity value it reads with the preset humidity threshold and calculates the deviation. The controller controls the power supply of the axial fan and humidification device based on the deviation value, which can reduce energy consumption and save electricity costs.

[0012] A further feature of this invention is that the humidification device includes: a water tank detachably connected inside the main body of the oil-filled radiator; a water pump fixedly installed above the water tank, electrically connected to a controller inside the main body of the oil-filled radiator; a water intake pipe connecting the water tank and the water pump to form a water inlet channel; several water permeable holes penetrating through the side wall of the main body of the oil-filled radiator, the axial direction of the water permeable holes forming a convection channel with the air outlet direction of the axial flow fan; a water outlet pipe connecting the water outlet of the water pump to form a water outlet channel, the water outlet pipe being arranged between the axial flow fan and the water permeable holes; and multiple spray heads mounted on the water outlet pipe, configured to atomize water and spray it into the airflow.

[0013] By adopting the above technical solution, after the water pump is turned on, water is drawn out of the water tank through the water pipe and sprayed out through the spray head on the water outlet pipe. Since the water outlet pipe is arranged between the axial fan and the water permeable hole, and the air outlet direction of the axial fan is convective with the axial direction of the water permeable hole, the water sprayed out through the spray head is blown by the axial fan through the water permeable hole to the outside of the electric oil heater body, thereby regulating the humidity of the external environment and reducing the stuffy feeling of the electric oil heater to the human body during use.

[0014] A further feature of this invention is that the main body of the electric oil heater has a cavity for inserting the water tank, a fixed stop protruding from the cavity, the fixed stop being located on the upper part of the water tank, a chamber being opened on the water tank, a drive mechanism being provided in the chamber, the water tank being inserted into the cavity, and the fixed stop locking the drive mechanism.

[0015] A further configuration of this utility model is as follows: the driving mechanism includes a movable block and a driving rod that actuates the movable block; the bottom of the movable block abuts against an elastic member, and the elastic member applies a force to the movable block toward the fixed stop; the movable block has an unlocked state in which it is actuated by the fixed stop or the driving rod and retracted into the cavity; and a locked state in which it extends out of the cavity and abuts against the fixed stop.

[0016] A further feature of this invention is that the fixed block and the movable block are provided with oppositely arranged guide slopes, and both the fixed block and the movable block are located in the placement trajectory of the water tank.

[0017] A further feature of this invention is that one end of the drive rod is inserted into the cavity and actuates the movable block away from the fixed stop block, and pressure rods extend from both sides of the movable block. The drive rod extends upward about the hinge position to form a pressure head, and the pressure head abuts against the pressure rod.

[0018] By adopting the above technical solution, the fixed block and the movable block are provided with oppositely arranged guide slopes. The fixed block and the movable block are preferably wedge-shaped blocks. The fixed block prevents the movable block from coming out, thereby locking the water tank. Therefore, when the water tank is in the combined state with the cavity, the water tank will be in a stable state during use and will not shake up and down. When the water tank needs to come out of the cavity, the elastic element abuts against the movable block, and the pressure head on the drive rod can compress the elastic element by pressing the pressure rods on both sides of the movable block, causing the movable block to move down and away from the fixed block. Since the water tank is fixed by the stop cooperation between the movable block set on the water tank and the fixed block in the cavity, it is only necessary to push up the drive rod on the surface of the water tank to drive the movable block to move away from the stop range of the fixed block, so that the water tank can come out smoothly. The structure is simple and the operation is convenient.

[0019] A further feature of this invention is that the fan speed control knob has an AUTO mode. When the fan speed control knob is rotated to this mode, the humidity sensor will automatically sense the indoor humidity. When the indoor humidity reaches a preset humidity threshold, the sensor will automatically control the power supply to and from the axial fan and the water pump.

[0020] By adopting the above technical solution, when the AUTO mode is selected, the humidity threshold is first preset on the controller. The humidity sensor will detect the ambient humidity in real time and output a signal to the controller. After receiving the humidity signal, the controller will compare the humidity value read with the preset humidity threshold and calculate the deviation. The controller will control the power supply of the axial fan and water pump according to the deviation value. Moreover, the user can choose whether to switch the control mode. The human-computer interaction is strong and the operation is convenient. When using this mode, it automatically senses changes in the environment and adjusts without manual intervention. It is intelligent and portable.

[0021] A further feature of this invention is that a heat dissipation hole is provided on the side wall of the electric oil heater body, corresponding to the axial fan.

[0022] By adopting the above technical solution, several heat dissipation holes are arranged along the vertical direction of the side wall of the electric oil heater body, and the axial fan and electronic components located inside the electric oil heater body can dissipate heat in a timely manner through the heat dissipation holes.

[0023] In summary, this utility model has the following beneficial effects:

[0024] The electric oil heater has an oil tank connected to one side of its main body, which contains an electric heating element. An axial fan is installed inside the main body and is electrically connected to an internal controller. A display screen is installed on the other side of the main body, and a temperature control knob and a fan speed control knob are located below the display screen in the same direction. The temperature control knob is electrically connected to the electric heating element in the oil tank, and the fan speed control knob is signal-coupled to the axial fan drive module, which features optimized human-machine interaction and precise temperature control.

[0034] The present invention will be further described below with reference to the accompanying drawings.

[0035] Example 1:

[0036] A type of electric oil heater that provides rapid thermal radiation humidification, such as Figure 1As shown, the device includes an electric oil heater body 1, an oil tank 2 connected to one side of the body 1, an electric heating element 21 disposed inside the oil tank 2, an axial fan 12 disposed inside the body 1, the axial fan 12 being electrically connected to an internal controller, a display screen 3 mounted on the other side of the body 1, a temperature control knob 31 and a fan speed control knob 32 disposed in the same direction below the display screen 3, the temperature control knob 31 being electrically connected to the electric heating element 21 inside the oil tank 2, and the fan speed control knob 32 being signal-coupled to the drive module of the axial fan 12.

[0037] The temperature control knob 31 is based on the potentiometer principle. Rotating it changes the resistance value, outputting different voltage signals corresponding to different temperature settings. The user sets the target temperature by rotating the knob 31, transmitting the voltage signal to the controller (not shown in the figure). The controller, a microcontroller, is located inside the oil heater body 1. On one side, the controller sends temperature data via the I²C / SPI protocol to drive the chip (such as HD44780) of the display screen 3, controlling the pixels to display on the screen. On the other side, it controls the energizing time of the heating element 21, providing the controller with a temperature threshold. A thermistor (not shown in the figure) is installed inside the oil tank 2. Thermistors detect oil temperature through resistance changes, a common and existing technology. Without going into too much detail, the thermistor, the electric heating element 21, the controller, and the temperature control knob 31 are located in the same circuit. The controller monitors the current temperature of the hot oil in the oil tank 2 in real time through the thermistor and compares it with the set target temperature to calculate the deviation. The controller controls the power-on time of the electric heating element 21 based on the deviation value to adjust the heating temperature. For example, if the preset temperature threshold is ≥20℃ and the set target temperature is 70℃, the controller controls the electric heating element 21 to heat continuously for 20-25 minutes until the temperature of the hot oil in the oil tank 2 reaches 70℃. Then, the controller controls the electric heating element 21 to turn off the power. After 10 minutes, the temperature of the hot oil in the oil tank 2 reaches 68℃, and then it continues to heat for another 3 minutes to rise back to 70℃, and the cycle repeats.

[0038] The fan speed control knob 32 is based on the potentiometer principle. When rotated, it changes the resistance value and outputs different voltage signals, corresponding to different fan speed settings. The user sets the target speed by rotating the fan speed control knob 32, and the voltage signal is transmitted to the controller (not shown in the figure). The type and location of the controller have been described above, so they will not be repeated here. The controller sends fan speed data through the I²C / SPI protocol to drive the chip (such as HD44780) of the display screen 3 to control the pixels to be displayed on the display screen 3. On the other hand, it is used to control the voltage of the axial fan 12 motor. A Hall effect sensor (not shown in the figure) is set in the main body 1 of the electric oil heater. The working principle of the Hall effect sensor is that the rotor is embedded with a magnetic ring, the Hall element detects the change of magnetic field, and outputs pulses when rotated. It is a very conventional existing technology, and the applicant will not elaborate on it here. The sensor, axial fan 12, controller, and fan speed control knob 32 are located in the same circuit. The controller monitors the current speed of the axial fan 12 motor inside the main body 1 of the electric oil heater in real time through the sensor and compares it with the set target speed to calculate the deviation. The controller controls the motor voltage of the axial fan 12 to change the speed according to the deviation value. For example, if the preset speed threshold is 1000 rpm and the set target speed is 800 rpm, the controller controls the voltage of the axial fan 12 motor to drop from 12V to 9.6V, so that the speed of the axial fan 12 slows down. Conversely, if the preset speed threshold is 1000 rpm and the set target speed is 1200 rpm, the controller controls the voltage of the axial fan 12 motor to rise from 12V to 14.4V, so that the speed of the axial fan 12 speeds up. Display screen 3 refreshes the temperature data and fan speed data sent by the controller at a fixed frequency to form a real-time data interface. Users can obtain the current temperature / speed, target temperature / speed, and operating status information of electric heating tube / axial fan in real time, which optimizes human-machine interaction and realizes precise temperature control and air volume control.

[0039] Preferably, a heat dissipation hole 10 is provided on the side wall of the electric oil heater body 1 at the position corresponding to the axial fan 12. Several heat dissipation holes 10 are provided along the vertical direction of the side wall of the electric oil heater body 1, so that the axial fan 12 and the electronic components located inside the electric oil heater body 1 can dissipate heat in a timely manner through the heat dissipation hole 10.

[0040] Example 2:

[0041] A type of electric oil heater that provides rapid thermal radiation humidification, such as Figure 2-7 As shown, the difference between this embodiment and specific embodiment one is that:

[0042] The main body 1 of the electric oil heater is also equipped with a humidification device, which includes: a water tank 41, which is detachably connected to the inside of the main body 1; a water pump 42, which is fixedly installed above the water tank 41 and electrically connected to a controller inside the main body 1; a water intake pipe 43, which connects the water tank 41 and the water pump 42 to form a water inlet channel; a water outlet pipe 44, which connects to the outlet of the water pump 42 to form a water outlet channel, and is arranged between the axial fan 12 and the water permeable hole 11; multiple spray heads 45, which are located on the water outlet pipe 44 and are configured to atomize water and spray it into the airflow; and several water permeable holes 11, which are opened through the side wall of the main body 1, and the axial direction of the water permeable holes 11 forms a convection channel with the air outlet direction of the axial fan 12. After the water pump 42 is turned on, water is drawn out of the water tank 41 through the water pipe 43 and sprayed out through the spray head 45 on the water outlet pipe 44. Since the water outlet pipe 44 is arranged between the axial fan 12 and the water permeable hole 11, and the air outlet direction of the axial fan 12 is convective with the axial direction of the water permeable hole 11, the water sprayed out through the spray head 45 is blown out of the electric oil heater body 1 through the water permeable hole 11 under the blowing of the axial fan 12, thereby regulating the humidity of the external environment and reducing the stuffy feeling of the electric oil heater to the human body during use.

[0043] The main body 1 of the electric oil heater has a groove forming a cavity 46 on its side wall. The cavity 46 is used to accommodate the water tank 41. A fixed stop 461 protrudes from the cavity 46 and is located on the upper part of the water tank 41. The water tank 41 also has a chamber 411, which contains a driving mechanism. The driving mechanism includes a movable block 412 that is movably disposed relative to the fixed stop 461, and a driving rod 413 that actuates the movable block 412. The movable rod 413 is at least partially exposed on the surface of the water tank 41. The fixed block 461 and the movable block 412 are provided with oppositely arranged guide slopes, and both the fixed block 461 and the movable block 412 are located in the insertion trajectory of the water tank 41. The movable block 412 has an unlocked state that is actuated by the fixed block 461 or the drive rod 413 and retracted into the chamber 411; and a locked state that extends out of the chamber 411 and abuts against the fixed block 461. The driving mechanism includes an elastic element 414 that abuts against the movable block 412. The elastic element 414 applies a force to the movable block 412 toward the fixed stop 461. One end of the driving rod 413 is inserted into the chamber 411 and actuates the movable block 412 away from the fixed stop 461. Pressure rods 415 extend from both sides of the movable block 412. The driving rod 413 extends upward about the hinge position to form a pressure head 416, and the pressure head 416 abuts against the pressure rod 415. The fixed stop 461 and the movable block 412 are provided with oppositely arranged guide slopes. The fixed stop 461 and the movable block 412 are preferably wedge-shaped blocks. The fixed stop 461 prevents the movable block 412 from dislodging, thus locking the water tank 41. Therefore, when the water tank 41 is engaged with the cavity 46, the water tank 41 will remain stable during use and will not wobble. When the water tank 41 needs to dislodge from the cavity 46, the elastic element 414 abuts against the movable block 412, and the pressure head 416 on the drive rod 413 can press the pressure rods 415 on both sides of the movable block 412 to... The elastic element 414 is compressed, causing the movable block 412 to move downward and move away from the fixed stop 461. Since the water tank 41 is fixed by the stop of the fixed stop 461 in the cavity 46, the drive rod 413 exposed on the surface of the water tank 41 and located on the side wall of the electric oil heater body 1 is pushed up, so that the pressure head 416 on the drive rod 413 can drive the movable block 412 to move away from the stop range of the fixed stop 461, so that the water tank 41 can be smoothly removed from the cavity 46 on the side wall of the electric oil heater body 1. The structure is simple and the operation is convenient.

[0044] Example 3: A rapid thermal radiation humidifying electric oil heater, such as... Figure 8 As shown, the difference between this embodiment and specific embodiment two is that:

[0045] The humidification device also includes a humidity sensor 6, which is located on the outer wall of the oil-filled radiator body 1. The humidity sensor 6 is electrically connected to the controller inside the oil-filled radiator body 1. The fan speed control knob 32 has an AUTO mode. When the fan speed control knob 32 is rotated to this mode, the humidity sensor 6 automatically senses the indoor humidity. When the indoor humidity reaches a preset humidity threshold, it automatically controls the power supply to the axial fan 12 and the water pump 42. A temperature sensor 5 is also located on the outer wall of the oil-filled radiator body 1. The temperature sensor 5 is electrically connected to the controller inside the oil-filled radiator body 1. The temperature control knob 31 has an AUTO mode. When the temperature control knob 31 is rotated to this mode, the temperature sensor 5 automatically senses the indoor temperature. When the indoor temperature reaches a preset temperature threshold, it automatically controls the power supply to the electric heating element 21 inside the oil tank 2.

[0046] The temperature sensor 5 is a thermistor, which is installed on the side wall of the oil-filled radiator body 1. Thermistors detect indoor temperature by changing resistance, which is a common existing technology and will not be elaborated on here. The thermistor, controller, temperature control knob 31, and electric heating element 21 are located in the same circuit. The temperature control knob 31 is based on the potentiometer principle. When rotated, it changes the resistance value and outputs different voltage signals. The user can switch to AUTO mode by rotating the temperature control knob 31, which transmits the voltage signal to the controller (not shown in the figure). The controller is a microcontroller located inside the oil-filled radiator body 1. The controller receives the temperature data sent by the thermistor in real time. The controller sends the current temperature data through the I²C / SPI protocol to drive the chip (such as HD44780) of the display screen 3 to control the pixels to be displayed on the display screen 3. The temperature sensor 5 can send temperature data to the controller in the following ways: the analog sensor outputs an analog signal, which is converted into a digital value by the controller's analog-to-digital converter module; or a digital sensor can be used to directly output a digital temperature value through protocols such as I2C and SPI. Then, a temperature threshold is preset for the controller. The controller compares the current indoor temperature value sent by the thermistor with the preset temperature threshold, calculates the deviation, and controls the power supply to the electric heating element 21 based on the deviation value to adjust the heating temperature. For example, the electric heating element 21 is turned off when the preset temperature threshold is 30°C and restarted when it is 25°C. When the temperature sensor 5 detects an indoor temperature of 30°C, the controller controls the electric heating element 21 to turn off the power through a relay (not shown in the figure) connected in series with it; when the temperature sensor 5 detects an indoor temperature of 25°C, the controller controls the electric heating element 21 to turn on the power through the relay connected in series with it. It features strong human-machine interaction and convenient operation. In this mode, it automatically senses environmental changes and adjusts accordingly, requiring no manual intervention, making it intelligent and portable.

[0047] The humidity sensor 6 is a capacitive humidity sensor, which is installed on the side wall of the oil-filled radiator body 1. Capacitive humidity sensors detect indoor humidity by detecting changes in capacitance caused by moisture absorption through hygroscopic materials; this is a common existing technology and will not be elaborated upon here. The capacitive humidity sensor 6, controller, fan speed control knob 32, and axial fan 12 are located in the same circuit. The fan speed control knob 32 is based on the potentiometer principle; rotating it changes the resistance value and outputs different voltage signals. The user switches to AUTO mode by rotating the fan speed control knob 32, transmitting the voltage signal to the controller (not shown in the figure). The controller is a microcontroller located inside the oil-filled radiator body 1. The controller receives humidity data sent by the fan speed control knob 32 in real time and sends the current humidity data via the I²C / SPI protocol to drive the display screen. A chip (such as HD44780) controls the pixel display on screen 3. A humidity threshold is preset for the controller. The controller compares the current indoor humidity value sent by the capacitive humidity sensor 6 with the preset humidity threshold, calculates the deviation, and controls the power supply of the axial fan 12 and water pump 42 based on the deviation value to regulate the indoor humidity. For example, when the preset humidity threshold is 30%, the axial fan 12 and water pump 42 are turned on, and when it is 60%, they are turned off. When the humidity sensor 6 detects an indoor humidity of 30%, the controller controls the power supply of the axial fan 12 and water pump 42 through a relay (not shown in the figure) connected in series with the axial fan 12 and water pump 42; when the humidity sensor 6 detects an indoor humidity of 60%, the controller controls the power supply of the axial fan 12 and water pump 42 through the relay connected in series with the axial fan 12 and water pump 42. This design offers strong human-machine interaction and convenient operation. In this mode, it automatically senses environmental changes and adjusts accordingly, requiring no manual intervention; it is intelligent and portable.

[0048] Preferably, the temperature sensor 5 and the humidity sensor 6 can also be provided with separate isolation covers to avoid errors in measuring indoor temperature and humidity caused by the heating function of the oil heater itself.
