[0026] Please refer to Figure 1 The embodiments of this application provide a bottle warmer, including a heat preservation cavity 1, a heating cavity 2, a first heater 3, a second heater 4, a fan 5, a buzzer, and a controller. The heating cavity 2 is disposed inside the heat preservation cavity 1, and the first heater 3 and the second heater 4 are both disposed outside the heating cavity 2. The first heater 3 is located at the bottom of the heating cavity 2, and the second heater 4 is disposed at a distance from the first heater 3. The fan 5 is disposed in the heat preservation cavity 1. A first temperature detector 21 is disposed at the bottom of the heating cavity 2, a second temperature detector 11 is disposed inside the heat preservation cavity 1, and a liquid level detector 22 is disposed on the side wall of the heating cavity 2. The controller is electrically connected to the first heater 3, the second heater 4, the fan 5, the buzzer, the first temperature detector 21, the second temperature detector 11, and the liquid level detector 22.
[0027] In other embodiments, a third temperature detector 23 is also provided on the side wall of the heating chamber 2, and the controller is electrically connected to the third temperature detector 23.
[0028] Both the first heater 3 and the second heater 4 can be selected as heating belts or heating pipes. The insulation cavity 1 is provided with an air inlet and an air outlet. The fan 5 is used to form an air guide path between the air inlet and the air outlet to remove the heat in the insulation cavity 1. The fan 5 can send the hot air in the insulation cavity 1 out of the air outlet, or introduce the cold air from the outside into the air inlet.
[0029] like Figure 1 As shown, the fan 5 can be vertically placed on the side of the insulation cavity 1 to exhaust the hot air inside the insulation cavity 1 from the side; as Figure 2 As shown, the fan 5 can also be placed horizontally at the bottom of the insulation cavity 1 to exhaust the hot air inside the insulation cavity 1 downwards, or as... Figure 3 As shown, external cold air can also be introduced upwards into the insulation cavity 1.
[0030] Please refer to Figure 4 In some embodiments, embodiments of this application provide a bottle warmer temperature control method, applied to the aforementioned bottle warmer, the bottle warmer temperature control method comprising: Step S1: Control the first heater 3 to start, so as to heat the milk in the heating chamber 2.
[0031] Step S2: Obtain the liquid level signal from the liquid level detector 22 to determine whether the milk volume in the heating chamber 2 has reached the preset amount. If the milk volume in the heating chamber 2 has reached the preset amount, control the second heater 4 to start heating the milk in the heating chamber 2.
[0032] Step S3: Obtain the temperature signal from the third temperature detector 23 to determine whether the milk temperature in the heating chamber 2 has reached the first preset temperature. If the milk temperature in the heating chamber 2 has reached the first preset temperature, control the second heater 4 to stop operating.
[0033] Step S4: Obtain the temperature signal from the first temperature detector 21 to determine whether the milk temperature in the heating chamber 2 has reached the second preset temperature. If the milk temperature in the heating chamber 2 has reached the second preset temperature, control the first heater 3 to stop running and control the fan 5 to start.
[0034] Step S5: Obtain the temperature signal from the second temperature detector 11 to determine whether the temperature of the insulation cavity 1 has reached the third preset temperature. If the temperature of the insulation cavity 1 reaches the third preset temperature, control the fan 5 to stop running.
[0035] In the above steps, the controller first activates the first heater 3 to heat the milk in the heating chamber 2; then, the level detector 22 detects the amount of milk in the heating chamber 2 to generate a level signal. The controller determines whether the amount of milk in the heating chamber 2 has reached a preset amount based on the level signal. If the amount of milk in the heating chamber 2 has reached the preset amount, the controller activates the second heater 4. At this time, the first heater 3 and the second heater 4 work together to heat the milk in the heating chamber 2; the third temperature detector 23 detects the temperature of the milk in the heating chamber 2 and generates a temperature signal. The controller determines whether the temperature of the milk in the heating chamber 2 has reached a first preset temperature (e.g., 35~40℃) based on this temperature signal. If the temperature of the milk in the heating chamber 2 has reached the first preset temperature... If the temperature is detected, the second heater 4 is stopped, while the first heater 3 remains operational. The first temperature detector 21 detects the milk temperature in the heating chamber 2 and generates a temperature signal. The controller determines whether the milk temperature in the heating chamber 2 has reached the second preset temperature (e.g., 37~42℃) based on this temperature signal. If the milk temperature in the heating chamber 2 reaches the second preset temperature, the first heater 3 is stopped, and the fan 5 is started. The second temperature detector 11 detects the temperature in the insulation chamber 1 and generates a temperature signal. The controller determines whether the temperature in the insulation chamber 1 has reached the third preset temperature (e.g., 45~50℃) based on this temperature signal. If the temperature in the insulation chamber 1 reaches the third preset temperature, the fan 5 is stopped.
[0036] During the heat dissipation process of the fan 5, the first temperature detector 21 and the third temperature detector 23 monitor the milk temperature in real time. When the milk temperature is lower than the fourth preset temperature (e.g., 37°C), the fan 5 is controlled to stop. If the first temperature detector 21 detects that the milk temperature is lower than the fourth preset temperature, the first heater 3 is controlled to start. If the third temperature detector 23 detects that the milk temperature is lower than the fourth preset temperature, the second heater 4 is controlled to start, thereby achieving the heat preservation effect.
[0037] During the milk heating process, the first temperature detector 21 and the third temperature detector 23 monitor the milk temperature in real time. When the milk temperature is higher than the fifth preset temperature (e.g., 50°C), the first heater 3 and the second heater 4 are both stopped, and the fan 5 is started to discharge the excess heat from the heat preservation chamber 1.
[0038] Step S2 also includes: If the amount of milk in heating chamber 2 does not reach the preset amount, then proceed to step S4.
[0039] It should be noted that if the milk volume in heating chamber 2 does not reach the preset amount, it indicates that the milk volume in heating chamber 2 is low. At this time, there is no need to start the second heater 4. The first heater 3 can heat the milk to the second preset temperature. Once the controller determines that the milk temperature in heating chamber 2 has reached the second preset temperature, it controls the first heater 3 to stop running and controls the fan 5 to start.
[0040] Step S3 also includes: If the milk temperature in heating chamber 2 does not reach the first preset temperature, the first heater 3 and the second heater 4 will continue to operate.
[0041] It should be noted that the third temperature detector 23 monitors the milk temperature in the heating chamber 2 in real time. As long as the milk temperature in the heating chamber 2 does not reach the first preset temperature, the controller will control the first heater 3 and the second heater 4 to continue running until the milk temperature in the heating chamber 2 reaches the first preset temperature.
[0042] Step S4 also includes: If the milk temperature in heating chamber 2 does not reach the second preset temperature, then step S1 is executed again.
[0043] It should be noted that the first temperature detector 21 monitors the milk temperature in the heating chamber 2 in real time. If the milk temperature in the heating chamber 2 does not reach the second preset temperature, the controller will re-execute the previous steps S1-S3 until the milk temperature in the heating chamber 2 reaches the second preset temperature.
[0044] After step S5, the following also includes: Step S6: Obtain the preset working time of the bottle warmer. If the bottle warmer reaches the preset working time, control the buzzer to start; if the bottle warmer does not reach the preset working time, repeat step S1.
[0045] It should be noted that the preset working time is the countdown timer set for the bottle warmer. If the bottle warmer has reached the preset working time after the fan 5 stops, the countdown ends and the controller activates the buzzer to alert the user. If the bottle warmer has not reached the preset working time after the fan 5 stops, the controller will re-execute the previous steps S1-S5 to achieve cyclic heating.
[0046] Please refer to Figure 5 , Figure 6 In other embodiments, embodiments of this application also provide a bottle warmer temperature control method applied to a bottle warmer, wherein the third temperature detector 23 is eliminated, and the bottle warmer temperature control method includes: Step S1: Obtain the liquid level signal from the liquid level detector 22 to determine whether the milk volume in the heating chamber 2 has reached the preset amount. If the milk volume in the heating chamber 2 has reached the preset amount, control the first heater 3 and the second heater 4 to start simultaneously and operate at the first heating power to heat the milk in the heating chamber 2.
[0047] Step S2: Obtain the temperature signal from the first temperature detector 21 to determine whether the milk temperature in the heating chamber 2 has reached the first preset temperature. If the milk temperature in the heating chamber 2 has reached the first preset temperature, control the first heater 3 and the second heater 4 to operate at the second heating power to heat the milk in the heating chamber 2. The second heating power is less than the first heating power.
[0048] Step S3: Obtain the temperature signal from the first temperature detector 21 to determine whether the milk temperature in the heating chamber 2 has reached the second preset temperature. If the milk temperature in the heating chamber 2 has reached the second preset temperature, control the first heater 3 and the second heater 4 to stop operating and control the fan 5 to start.
[0049] Step S4: Obtain the temperature signal from the second temperature detector 11 to determine whether the temperature of the insulation cavity 1 has reached the third preset temperature. If the temperature of the insulation cavity 1 reaches the third preset temperature, control the fan 5 to stop running.
[0050] In the above steps, the level detector 22 detects the amount of milk in the heating chamber 2 to generate a level signal. The controller determines whether the amount of milk in the heating chamber 2 has reached a preset amount based on the level signal. If the amount of milk in the heating chamber 2 has reached the preset amount, the controller controls the first heater 3 and the second heater 4 to start simultaneously and operate at the first heating power. Subsequently, the controller determines whether the temperature of the milk in the heating chamber 2 has reached the first preset temperature based on the temperature signal from the first temperature detector 21. If the temperature of the milk in the heating chamber 2 has reached the first preset temperature, the controller controls the first heater 3 and the second heater 4 to reduce the heating power to the second heating power to continue heating the milk in the heating chamber 2. Subsequently, the controller determines whether the temperature of the milk in the heating chamber 2 has reached the second preset temperature based on the temperature signal from the first temperature detector 21. If the temperature of the milk in the heating chamber 2 has reached the second preset temperature, the controller controls the first heater 3 and the second heater 4 to stop operating and controls the fan 5 to start to reduce the temperature of the heat preservation chamber 1.
[0051] Step S1 also includes: If the milk volume in heating chamber 2 does not reach the preset amount, the first heater 3 and the second heater 4 are controlled to operate at the second heating power to heat the milk in heating chamber 2.
[0052] It should be noted that if the amount of milk in heating chamber 2 does not reach the preset amount, it indicates that the amount of milk in heating chamber 2 is low. In this case, it is only necessary to control the first heater 3 and the second heater 4 to operate at a lower second heating power to heat the milk in heating chamber 2 to a suitable temperature.
[0053] Step S2 also includes: If the milk temperature in heating chamber 2 does not reach the first preset temperature, the first heater 3 and the second heater 4 are controlled to continue operating at the first heating power.
[0054] It should be noted that if the milk temperature in heating chamber 2 does not reach the first preset temperature, the first heater 3 and the second heater 4 will be controlled to continue to operate at a higher first heating power until the milk temperature in heating chamber 2 reaches the first preset temperature.
[0055] Step S3 also includes: If the milk temperature in heating chamber 2 does not reach the second preset temperature, the first heater 3 and the second heater 4 are controlled to continue operating at the second heating power.
[0056] It should be noted that if the milk temperature in heating chamber 2 does not reach the second preset temperature, but since the first preset temperature has already been reached, the controller only needs to control the first heater 3 and the second heater 4 to continue operating at a lower second heating power until the milk temperature in heating chamber 2 reaches the second preset temperature.
[0057] After step S4, the following also includes: Step S5: Obtain the preset working time of the bottle warmer. If the bottle warmer reaches the preset working time, control the buzzer to start; if the bottle warmer does not reach the preset working time, repeat step S1.
[0058] It should be noted that the preset working time is the countdown timer set for the bottle warmer. If the bottle warmer has reached the preset working time after the fan 5 stops, the countdown ends and the controller activates the buzzer to alert the user. If the bottle warmer has not reached the preset working time after the fan 5 stops, the controller will re-execute the previous steps S1-S4 to achieve cyclic heating.
[0059] In summary, this application provides a bottle warmer and its temperature control method. The bottle warmer can adopt different heating modes according to the liquid level signal of the liquid level detector 22. Its controller can control the first heater 3 and the second heater 4 to heat the milk in the heating chamber 2 individually or simultaneously. After the milk is heated to a certain temperature, the controller can control the heater to stop and the fan 5 to start, so as to avoid the milk from overheating and losing nutrients. The first temperature detector 21 can detect the temperature in the heating chamber 2, and the second temperature detector 11 can detect the temperature in the heat preservation chamber 1, providing accurate temperature data to the controller. The controller can then accurately regulate the operation of the heater and the fan 5, thereby reducing the temperature control deviation of the milk and improving the temperature control accuracy.
