Description

Technical Field

[0001] This application relates to the technical field of intelligent household appliances, for example, to a method and device for adjusting the air volume of an auxiliary heating air conditioner and an intelligent air conditioner. Background Art

[0002] Currently, an electric heating device is usually provided on an air conditioner, such as a semiconductor electric heating device with a positive temperature coefficient (PTC), to improve the heating effect of the air conditioner. In some special cases, for example, the filter of the indoor unit of the air conditioner is too dusty, or the set air volume is too small, resulting in the heat generated by the electric heating device not being taken away by the wind in time, so that the surface temperature of the electric heating device is too high, which will trigger the temperature protector of the electric heating device to act, causing the electric heating device to power off and stop heating, thus affecting the indoor heating effect.

[0003] To improve the heating effect of the electric heating device, the existing air conditioner control method can be improved. For example, by real-time detecting the working temperature of the electric heating device and adjusting the working state of the air conditioner according to the real-time temperature of the electric heating, when the working temperature of the electric heating device rises, the wind speed and the air volume are adjusted to improve the heat circulation efficiency, reduce the working temperature of the electric heating device, and thus reduce the phenomenon of the electric heating device powering off, improving the heating effect of the electric heating device.

[0004] In the process of implementing the embodiments of the present application, it is found that there are at least the following problems in the related art:

[0005] The temperature protector of the electric heating device usually uses a thermosensitive switch with relatively low cost, but the thermosensitive switch cannot detect the working temperature of the electric heating device. To detect the working temperature of the electric heating device, a temperature sensor usually needs to be additionally provided in the air conditioner. Although this solution can reduce the action of the temperature protector of the electric heating device, the additional temperature sensor increases the production cost of the air conditioner.

It should be understood that such data can be interchanged under appropriate circumstances so as to implement the embodiments of this application described herein.

[0033] The term "and / or" is a description of the associated relationship of an object, indicating that there can be three relationships. For example, A and / or B means: A or B, or, A and B these three relationships.

[0034] Figure 1It is a schematic diagram of an electronic control module of an auxiliary heating air conditioner provided by an embodiment of the present application. The auxiliary heating air conditioner in the embodiment of the present application refers to an air conditioner including an electric heating device. During the heating process of the auxiliary heating air conditioner, the condenser of the auxiliary heating air conditioner has a heating function, and the electric heating device also has a heating function. Here, the electric heating device can be a PTC semiconductor electric heating device.

[0035] As Figure 1 shown, the auxiliary heating air conditioner includes a controller 11, an electric heating device 12, a temperature protector 13, and an air volume adjustment device 14.

[0036] The controller 11 is connected to the electric heating device 12. The controller 11 can read the on / off state of the electric heating device 12. For example, a relay that controls the on / off of the electric heating device 12 can send the action state of the relay to the controller 11, enabling the controller 11 to obtain the on / off state of the electric heating device 12.

[0037] The electric heating device 12 is connected to the temperature protector 13. The temperature sensing element in the temperature protector 13 (such as a temperature sensing element composed of a bimetallic strip) can deform at the temperature of the electric heating device 12. Then, when the temperature of the electric heating device 12 is too high, the temperature protector 13 switches the electric heating device 12 from the on state to the off state. For example, the temperature protector 13 sends a control signal to the relay that powers on the electric heating device 12, causing the relay that powers on the electric heating device 12 to switch from the closed state to the open state.

[0038] The controller 11 is connected to the air volume adjustment device 14. The air volume adjustment device 14 can act under the control of the controller 11 to adjust the air volume of the indoor unit of the air conditioner. For example, the air volume adjustment device 14 can include the fan of the indoor unit of the air conditioner and / or the drive motor of the air deflector of the indoor unit of the air conditioner. By adjusting the rotation speed of the fan of the indoor unit of the air conditioner and / or changing the angle of the drive motor to change the opening degree of the air deflector, the air volume output from the indoor unit of the air conditioner can be adjusted.

[0039] Different from the prior art that adjusts the air volume by detecting the accurate temperature of the electric heating device, the air volume adjustment method provided in the embodiment of the present application adjusts the air volume of the indoor unit of the air conditioner only relying on the overheat protection measures of the electric heating device itself when the accurate temperature of the electric heating device cannot be obtained, and improves the heating effect of the electric heating device.

[0040] Figure 2 It is a schematic flowchart of an air volume adjustment method for an auxiliary heating air conditioner provided by the present application. The air volume adjustment method of the auxiliary heating air conditioner can be executed by the controller of the air conditioner, can be executed by a control panel communicatively connected to the air conditioner, or can be executed by a server communicatively connected to the air conditioner.

[0041] Combined with Figure 2As shown, the air volume adjustment method of the auxiliary heating air conditioner includes:

[0042] S201. In the auxiliary heating mode, obtain the on / off state of the electric heating device.

[0043] The auxiliary heating air conditioner includes an auxiliary heating mode and a non-auxiliary heating mode. When the indoor temperature is not too low, for example, when the indoor temperature is greater than the set lower limit ambient temperature, the auxiliary heating air conditioner operates in the non-auxiliary heating mode. At this time, the auxiliary heating air conditioner heats the indoor air through the condenser; when the indoor temperature is too low, for example, when the indoor temperature is less than the set lower limit ambient temperature, the auxiliary heating air conditioner operates in the auxiliary heating mode. At this time, the auxiliary heating air conditioner heats the indoor air through the condenser and the electric heating device.

[0044] Alternatively, a user instruction can be received and the auxiliary heating mode or the non-auxiliary heating mode can be entered in response to the user instruction.

[0045] The on / off state of the electric heating device can be determined by obtaining the on / off state of the relay that supplies the working current to the electric heating device. Alternatively, the working current of the auxiliary heating air conditioner is detected. When the operating state of the auxiliary heating air conditioner (such as the compressor frequency, the indoor fan speed, the outdoor fan speed, etc.) does not change and the working current of the air conditioner shows a stepwise increase, it is determined that the electric heating device has switched from the off state to the on state.

[0046] S202. When the electric heating device switches from the off state to the on state for the non-first time, obtain the current air volume of the indoor unit of the air conditioner and the air volume compensation amount.

[0047] In the embodiments of the present application, the air volume refers to the air circulation volume per unit time. For example, the units of the current air volume and the air volume compensation amount can be cubic meters per second.

[0048] When the auxiliary heating air conditioner first enters the auxiliary heating mode, the electric heating device switches from the off state to the on state for the first time. At this time, there are two situations: the first situation is that the air volume of the air conditioner makes the heat dissipation rate of the electric heating device equal to the heating rate of the electric heating device; the second situation is that the air volume of the air conditioner makes the heat dissipation rate of the electric heating device less than the heating rate of the electric heating device. The second situation may be caused by a low rotation speed of the air conditioner or serious blockage and dirt of the filter of the indoor unit of the air conditioner.

[0049] In the second case, the temperature of the electric heating device will continue to rise until the overheat protection is triggered by the temperature protection device corresponding to the electric heating device, causing the electric heating device to switch from the powered-on state to the powered-off state. After that, the temperature of the electric heating device continues to drop until it is lower than or equal to the protection release temperature, and then the electric heating device switches from the powered-off state to the powered-on state. This switching process is the second time the electric heating device switches from the powered-off state to the powered-on state in the auxiliary heating mode. In the switching processes from the powered-off state to the powered-on state after this time, they all belong to the cases where the electric heating device switches from the powered-off state to the powered-on state not for the first time.

[0050] The current air volume output of the indoor unit of the air conditioner can be represented by the fan speed and / or the deflector opening degree of the indoor unit of the air conditioner; thus, obtaining the current air volume output of the indoor unit of the air conditioner can include: obtaining the current fan speed of the indoor unit of the air conditioner and / or the current deflector opening degree of the indoor unit of the air conditioner.

[0051] The air volume compensation amount can be preset; when the current air volume output is represented by the current fan speed, the air volume compensation amount can be a preset fan speed. For example, the preset fan speed can be 1 / 10, 1 / 9, 1 / 8, 1 / 7, 1 / 6, 1 / 5, or 1 / 4 of the maximum fan speed of the indoor unit of the air conditioner; when the current air volume output is represented by the current deflector opening degree, the air volume compensation amount can be a preset deflector opening degree. For example, the preset deflector opening degree can be 1 / 10, 1 / 9, 1 / 8, 1 / 7, 1 / 6, or 1 / 5 of the maximum deflector opening degree of the indoor unit of the air conditioner; when the current air volume output is represented by the current fan speed and the current deflector opening degree, the air volume compensation amount can be a preset fan speed and / or a preset deflector opening degree, and the preset fan speed and the preset deflector opening degree are set with reference to the above.

[0052] Alternatively, the air volume compensation is calculated. For example, obtaining the air volume compensation amount can include: obtaining the continuous heating duration of the electric heating device between the last time the electric heating device switches from the powered-off state to the powered-on state and then from the powered-on state to the powered-off state; obtaining the power-off duration of the electric heating device between the last time the electric heating device switches from the powered-on state to the powered-off state and then from the powered-off state to the powered-on state; and obtaining the air volume compensation amount that is negatively correlated with the continuous heating duration and positively correlated with the power-off duration.

[0053] By using the continuous heating time and the power-off time to measure the increase in the heat dissipation rate required by the electric heating device, not only can the air volume compensation amount meet the heat dissipation demand of the electric heating device as much as possible and improve the heating effect of the auxiliary heating air conditioner, but also the value of the air volume compensation amount can be reduced as much as possible to reduce the discomfort caused to the user by the increase in air volume. In the embodiment of the present application, the continuous heating time can reflect the difference rate between the heating rate and the heat dissipation rate of the electric heating device. The longer the continuous heating time, the smaller the difference rate, and the shorter the continuous heating time, the larger the difference rate; the power-off time can reflect the heat dissipation rate of the electric heating device. The longer the power-off time, the smaller the heat dissipation rate of the electric heating device, and the longer the power-off time, the larger the heat dissipation rate of the electric heating device. This is not the first time that the electric heating device switches from the power-off state to the power-on state, indicating that the heat dissipation rate of the electric heating device cannot meet the heat dissipation demand of the electric heating device at this time, and the heat dissipation rate of the electric heating device needs to be increased. The air volume compensation amount is positively correlated with the power-off duration, and the air volume can be further increased to increase the heat dissipation rate of the electric heating device as soon as possible; the air volume compensation amount is negatively correlated with the continuous heating duration, and the air volume is increased at a relatively slow growth rate to minimize the discomfort caused to the user by the increase in air volume. Finally, the technical solution in the embodiment of the present application can not only make the air volume compensation amount meet the heat dissipation demand of the electric heating device as much as possible and improve the heating effect of the auxiliary heating air conditioner, but also reduce the value of the air volume compensation amount as much as possible to reduce the discomfort caused to the user by the increase in air volume.

[0054] In some application scenarios, the moment when the electric heating device switches from the power-off state to the power-on state is recorded as the first moment; then the electric heating device is powered on and operated, and because the heat dissipation rate of the electric heating device is lower than its heating rate, at a certain moment, the electric heating device switches from the power-on state to the power-off state, and this moment is recorded as the second moment; then the electric heating device is in the power-off state, and as the temperature of the electric heating device gradually decreases, at another moment, the electric heating device switches from the power-off state to the power-on state again, and this moment is recorded as the third moment. In this way, the continuous heating duration can be obtained by subtracting the first moment from the second moment; the power-off duration can be obtained by subtracting the second moment from the third moment.

[0055] Specifically, a quantitative amount of air volume compensation can be obtained in the following manner: obtain the ratio of the power-off duration to the continuous heating duration, and a first product of the ratio and the current air volume; and determine the air volume compensation amount based on the first product.

[0056] Wherein, determining the wind volume compensation amount according to the first product may include: determining the first product as the wind volume compensation amount; or, determining the first product and the second product of the protection coefficient as the wind volume compensation amount; wherein the protection coefficient is less than 1.

[0057] The protection coefficient here is used to adjust the size of the air volume compensation as a whole. In specific applications, if the electric heating device frequently switches between the powered-on state and the powered-off state, the protection coefficient can be appropriately increased; if the air volume becomes too large after adjusting the air volume, causing discomfort to the user, the protection coefficient can be appropriately decreased. In this way, through the balanced adjustment of this protection coefficient, the auxiliary heating air conditioner can maintain a better heating effect, and at the same time, the user can have a better blowing experience.

[0058] S203. Adjust the air volume of the indoor unit of the air conditioner according to the sum of the air volume compensation and the current air volume.

[0059] For example, the current air volume of the indoor unit of the air conditioner can be increased by the air volume compensation, that is, the air volume of the indoor unit of the air conditioner is adjusted to the sum of the air volume compensation and the current air volume.

[0060] In the specific adjustment process, if the air volume compensation is represented by a preset fan speed, the fan speed of the indoor unit of the air conditioner is increased. For example, the current fan speed of the indoor unit of the air conditioner is increased by the preset fan speed; if the air volume compensation is represented by a preset air deflector opening, the air deflector opening of the indoor unit of the air conditioner is increased. For example, the current air deflector opening of the indoor unit of the air conditioner is increased by the preset air deflector opening; if the air volume compensation is represented by a preset fan speed and a preset air deflector opening, the fan speed and / or the air deflector opening of the indoor unit of the air conditioner is increased. For example, the current fan speed of the indoor unit of the air conditioner is increased by the preset fan speed, or the current air deflector opening of the indoor unit of the air conditioner is increased by the preset air deflector opening, or the current fan speed of the indoor unit of the air conditioner is increased by the preset fan speed, and at the same time, the current air deflector opening of the indoor unit of the air conditioner is increased by the preset air deflector opening.

[0061] In the case of overheating of the electric heating device, the on-off state of the electric heating device switches from the powered-on state to the powered-off state. The temperature protector of the electric heating device itself is used to monitor the overheated state of the electric heating device, and then the air volume of the indoor unit of the air conditioner is increased to enable the electric heating device to achieve a better heating effect; all the hardware relied on in the above process of improving the heating effect are the default hardware of a conventional air conditioner, and there is no need to set additional hardware such as a temperature sensor on the indoor unit of the air conditioner, reducing the production cost of the air conditioner.

[0067] S304. When the sum of the air volume compensation and the current air volume is greater than or equal to the maximum air volume of the air conditioner indoor unit, adjust the air volume of the air conditioner indoor unit according to the maximum air volume.

[0070] S401. Obtain the on / off state of the electric heating device in the auxiliary heating mode.

[0071] S402. Determine whether the electric heating device switches from the power-off state to the power-on state for the non-first time; if so, execute S403; otherwise, execute S401.
