[0043] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0044] It should be understood that the "plurality" mentioned herein refers to two or more. In the description of the embodiments of the present application, unless otherwise specified, " / " means "or". For example, A / B may represent A or B; the "and / or" herein is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in order to clearly describe the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish the same items or similar items with basically the same functions and roles. Those skilled in the art can understand that the words such as "first" and "second" do not limit the quantity and execution order, and the words such as "first" and "second" do not necessarily limit to be different.

[0045] In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily limit to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0046] Since currently when the air conditioner enters the defrosting mode in the heating mode, the reverse cycle method is usually adopted for defrosting. This method switches the heating condition to the cooling condition. At this time, the outdoor heat exchanger functions as a condenser, and the refrigerant condenses and releases heat in the condenser, so that the frost layer on the surface of the outdoor heat exchanger melts. This process will cause the air conditioner to suspend heating or reduce the heating capacity, and absorb heat from the room, thereby causing the room temperature to drop and affecting the comfort of users.

[0047] To solve the above technical problems, the present application proposes an air outlet assembly, an indoor unit, an air conditioner, an electronic device and a control method. Among them, the air outlet assembly includes a main body and a phase change energy storage unit provided on the main body;

[0048] The phase change energy storage unit includes an electromagnetic part and a phase change energy storage part. The electromagnetic part can generate an electromagnetic field in the energized state, and the phase change energy storage part can absorb or release heat through phase change under the action of the electromagnetic field to adjust the air outlet temperature of the air outlet assembly.

[0049] In this embodiment, by providing a phase change energy storage unit on the main body of the air outlet assembly, the electromagnetic field generated by the electromagnetic part of the phase change energy storage unit enables the phase change energy storage part of the phase change energy storage unit to release heat or absorb heat, so that when the air conditioner enters the defrosting, the heat stored in the phase change energy storage part can be released to reduce the fluctuation of the indoor temperature, improve the stability of the indoor temperature, and avoid excessive drop of the indoor temperature during the defrosting process, which affects the comfort experience of users. After the defrosting is completed, the phase change energy storage part absorbs heat to store heat for the next defrosting process.

[0050] The technical solution of this embodiment will be elaborated in detail below in conjunction with the accompanying drawings. Under the condition of no conflict, the following embodiments and examples can be combined with each other.

[0051] This embodiment proposes an air outlet component, which is used for an indoor unit and has the function of guiding and / or assisting the air outlet of the indoor unit. The air outlet component includes a main body and a phase change energy storage unit provided on the main body. The phase change energy storage unit includes an electromagnetic part and a phase change energy storage part 3. The electromagnetic part can generate an electromagnetic field in the energized state, and the phase change energy storage part 3 can absorb or release heat through phase change under the action of the electromagnetic field to adjust the air outlet temperature of the air outlet component.

[0052] The electromagnetic part is, for example, an electromagnet or an electric field generator. The phase change energy storage part 3 includes a material capable of solid-liquid phase change, such as paraffin or other modified materials, and its phase change temperature range matches the operating temperature range of the air conditioner.

[0053] In the case of a relatively low ambient temperature, the phase change energy storage part 3 can release heat to increase the ambient temperature; in the case of a relatively high ambient temperature, the phase change energy storage part 3 can absorb ambient heat to store heat. The absorption or release of heat by the phase change energy storage part 3 can be achieved through the electromagnetic field generated by the electromagnetic part, or the electromagnetic part can generate an electromagnetic field to release heat when the ambient temperature is low and release heat autonomously when the ambient temperature is high, or it can release heat autonomously when the ambient temperature is low and absorb heat through the electromagnetic field generated by the electromagnetic part when the ambient temperature is high. In practical applications, the heat absorption or heat release method of the phase change energy storage part 3 can be flexibly selected by comprehensively considering aspects such as the application scenario, the phase change temperature of the phase change material, and the energy demand.

[0054] The air outlet component of this embodiment can be realized that in the defrosting scenario, the phase change energy storage unit releases heat to increase the indoor temperature to reduce the fluctuation of the indoor temperature, and after the defrosting ends, the phase change energy storage unit absorbs heat to store heat to provide heat for the next defrosting. In other application scenarios, for example, in the high-temperature refrigeration condition, the phase change energy storage unit can also be used to absorb heat to accelerate the indoor cooling, and after the indoor temperature drops to the target temperature, it can also release heat to store cold, so as to assist the indoor cooling in the subsequent room temperature adjustment process.

[0055] In one example, the air outlet component includes a guiding vane 2, the main body includes a guiding vane main body, a phase change energy storage part 3 is arranged on the guiding vane main body, and an electromagnetic part is arranged at at least one end or at least one side of the guiding vane main body. In one example, the electromagnetic part is arranged at one end or one side in the length direction of the guiding vane main body, or is arranged at one end or one side in the width direction of the guiding vane main body. In another example, the electromagnetic part is arranged at opposite ends or both sides in the length direction of the guiding vane main body, or is arranged at both ends or both sides in the width direction of the guiding vane main body, so that the electromagnetic part can generate a uniform electromagnetic field at the position where the phase change energy storage part 3 is located, and improve the phase change effect of the electromagnetic field on the phase change energy storage part 3.

[0056] It should be noted that the electromagnetic part arranged at one end of the guiding vane main body in this embodiment means that the electromagnetic part is directly arranged on the guiding vane main body. The electromagnetic part arranged at one side of the guiding vane main body means that the electromagnetic part is not arranged on the guiding vane main body, but on other components near the guiding vane main body of the indoor unit of the air conditioner. For example, the guiding vane main body is arranged in the air outlet frame 1, and the electromagnetic part is located on the air outlet frame 1 on one side of the guiding vane main body.

[0057] In another example, as Figure 1 shown, the air outlet component includes an air outlet frame 1 and a guiding vane 2, the main body includes a guiding vane main body, the air outlet frame 1 is provided with an air outlet 11, and the guiding vane main body is arranged in the air outlet frame 1 and located inside the air outlet 11. Preferably, the guiding vane main body is rotatably arranged inside the air outlet 11 to adjust the air outlet direction of the air outlet 11. The phase change energy storage part 3 is arranged on the guiding vane main body, and the electromagnetic part is arranged on the air outlet frame 1 and located at one end or opposite ends of the air outlet 11. Preferably, the electromagnetic part is arranged at opposite ends of the air outlet frame 1 so that the electromagnetic part can generate a uniform electromagnetic field at the position where the phase change energy storage part 3 is located, and improve the effect of the electromagnetic field on the phase change energy storage part 3.

[0058] Preferably, there are multiple guiding vanes 2, and the multiple guiding vanes 2 are arranged along the width direction of the air outlet 11 main body, and the guiding vane main body of at least one guiding vane 2 is provided with a phase change energy storage part 3. Preferably, each guiding vane main body is provided with a phase change energy storage part 3 to increase the heat release amount and heat absorption amount of the phase change energy storage part 3 and improve the indoor temperature regulation effect. Further preferably, the phase change energy storage part 3 is arranged on the same side of multiple guiding vane main bodies to improve the aesthetic appearance of the air outlet component of the air conditioner.

[0059] In this embodiment, by arranging the phase change energy storage part 3 on the guiding vane main body, when the guiding vane 2 is arranged at the air outlet 11 of the indoor unit, when the phase change energy storage part 3 releases heat, the released heat can enter the room along with the air outlet. When the phase change energy storage part 3 absorbs heat, it can absorb the heat in the air flow blown into the room by the air outlet frame 1, and improve the indoor temperature regulation effect.

[0060] In other realizable ways, the air outlet component includes an air outlet frame 1, the main body includes the main body of the air outlet frame 1, the air outlet frame 1 is provided with an air outlet 11, the phase change energy storage part 3 is arranged on the peripheral wall of the air outlet 11, and the electromagnetic part is arranged on the air outlet frame 1 and is located at one end or opposite ends of the air outlet 11. At this time, the heat absorption and heat release of the phase change energy storage unit can also be realized, and the effect is similar to that when the phase change energy storage part 3 is arranged on the air guide vane main body, which will not be elaborated here.

[0061] In an optional implementation, the phase change energy storage part 3 is embedded on the surface of the air guide vane main body. For example, a groove is provided on the surface of the air guide vane main body, and the phase change energy storage part 3 is embedded in the groove. Among them, the groove can be formed by being recessed inward from the surface of the air guide vane main body, or can be a groove protruding outward from the surface of the air guide vane main body, that is, the groove protrudes outward from the surface of the air guide vane main body. In one example, the phase change energy storage part 3 is in the form of micron-sized phase change microcapsules, and a plurality of phase change microcapsules are embedded in the groove of the air guide vane main body.

[0062] And / or, the phase change energy storage part 3 is a temperature regulation coating coated on the surface of the air guide vane main body. In one example, the phase change energy storage part 3 is in the form of micron-sized phase change microcapsules, and a plurality of phase change microcapsules are sprayed on the surface of the air guide vane 2 to form a temperature regulation coating.

[0063] In this embodiment, the phase change energy storage part 3 is embedded and / or coated on the surface of the air guide vane main body to improve the heat release or absorption efficiency of the phase change energy storage part 3.

[0064] In an optional implementation, as Figure 2 shown, the phase change energy storage unit includes a housing 31 and a core 32, and the housing 31 wraps around the outside of the core 32. The housing 31 includes a material that can change its volume under the action of an electromagnetic field, for example, includes a shape memory material with electromagnetic response characteristics, such as a magnetic shape memory alloy or an electroactive polymer. The core 32 includes a phase change material, for example, a solid-liquid phase change material is selected, such as paraffin or its modified material, and its phase change temperature range matches the operating temperature range of the air conditioner.

[0065] When the electromagnetic part generates an electromagnetic field and applies it to the housing 31 of the phase change energy storage part 3, since the housing 31 will deform under the action of the electromagnetic field, its volume will change (expand or contract), and the change in the volume of the housing 31 will change the phase change conditions (such as pressure or temperature) of the core 32, thereby triggering the phase change process of the core 32 to release or absorb heat. During the process of applying the electromagnetic field to the phase change energy storage part 3, it is preferably to adopt a low-frequency application method to ensure the stable change of the volume of the housing 31 and the full phase change of the material of the core 32.

[0066] In this embodiment, a housing 31 made of a material that can change its volume under the action of an electromagnetic field is used to wrap the core 32, forming a receiving space for the core 32 to prevent the core 32 from leaking in the liquid state. At the same time, the change in the shape of the housing 31 will also change the phase change conditions of the core 32, which helps to trigger the phase change of the core 32, ensuring the absorption or release of heat by the core 32 and further improving the effect of adjusting the indoor temperature.

[0067] In an alternative implementation, the electromagnetic part can generate an electromagnetic field with variable intensity and / or direction, and the housing 31 has a variable volume under electromagnetic fields of different intensities and / or different directions. Specifically, when the direction of the current flowing through the electromagnetic part is the first direction, the first electromagnetic field generated by the electromagnetic part causes the housing 31 to expand; when the direction of the current flowing through the electromagnetic part is the second direction, the second electromagnetic field generated by the electromagnetic part causes the housing 31 to contract; the first direction is opposite to the second direction. In practical applications, the direction of the electromagnetic field can be changed by changing the direction of the current flowing through the electromagnetic part, and the intensity of the electromagnetic field can be adjusted by changing the magnitude of the current flowing through the electromagnetic part.

[0068] This embodiment can use the indoor comfort temperature as a measurement standard, change the direction of the electromagnetic field generated by the electromagnetic part according to the change of the indoor environmental temperature, so as to change the volume of the housing 31 of the phase change energy storage part 3, so that the core 32 of the phase change energy storage part 3 undergoes a phase change to release heat or absorb heat. At the same time, it can also dynamically adjust the application interval and application intensity of the electromagnetic field to avoid energy waste caused by excessive phase change of the phase change energy storage part 3.

[0069] This embodiment also proposes an indoor unit, which includes the air outlet assembly proposed above.

[0070] This embodiment also proposes an air conditioner, which includes an outdoor unit and the indoor unit proposed above.

[0071] During the operation of the indoor unit and the air conditioner of this embodiment, the fluctuation of the indoor environmental temperature can be reduced, the stability of the indoor temperature during the defrosting process in the heating mode can be ensured, and the comfort experience of the user during the heating and defrosting process can be improved.

[0072] This embodiment also proposes a control method for an air conditioner. The control method is applied to the air conditioner proposed above. Referring to Figure 3 the control flowchart, the control method includes the following steps:

[0073] S301. In the heating mode, determine the defrosting state of the air conditioner. The defrosting state includes the defrosting working state and the non-defrosting state;

[0074] S302. Control the working state of the electromagnetic part at least according to the defrosting state.

[0075] Specifically, in the heating mode, the temperature sensor is used to detect the surface temperature of the outdoor heat exchanger, and then determine the frosting condition of the outdoor heat exchanger. According to the frosting condition, the defrosting state of the air conditioner can be judged, so that the working state of the electromagnetic part can be controlled according to the defrosting state, and when the air conditioner enters the defrosting working state, the heat released by the phase change energy storage unit can be used to adjust the indoor temperature to ensure the stability of the indoor temperature.

[0076] In one example, controlling the working state of the electromagnetic part at least according to the defrosting state includes: when the air conditioner is in the defrosting working state, controlling the electromagnetic part to generate a first electromagnetic field, and controlling the working state of the electromagnetic part at least according to the indoor temperature; wherein, the first electromagnetic field is an electromagnetic field capable of causing the phase change energy storage part 3 to release heat.

[0077] In this embodiment, when the air conditioner is in the defrosting working state, it is described that the indoor temperature will decrease. At this time, the electromagnetic part can be controlled to be in the state of generating the first electromagnetic field, so that the phase change energy storage part 3 releases heat. Specifically, the first electromagnetic field can cause the housing 31 of the phase change energy storage unit to contract. The contraction of the volume of the housing 31 increases the pressure on the core 32, and the increase in pressure promotes the transformation of the core 32 from the liquid state to the solid state, releasing latent heat to the room.

[0078] When the electromagnetic part generates the first electromagnetic field, the working state of the electromagnetic field is also dynamically adjusted at least according to the indoor ambient temperature to avoid energy waste caused by excessive phase change of the phase change energy storage unit.

[0079] Wherein, the working state of the electromagnetic part includes at least one of the starting state of the electromagnetic part, the intensity of the electromagnetic field generated by the electromagnetic part, the direction of the electromagnetic field generated by the electromagnetic part, and the interval of the electromagnetic field generated by the electromagnetic part.

[0080] When the air conditioner is in the non-defrosting state, the current operating state of the air conditioner can be maintained.

[0081] When the air conditioner exits the defrosting working state, the air conditioner switches from the refrigeration condition to the heating condition, and the indoor ambient temperature will rise, and there is no need for the phase change energy storage part 3 to provide heat. In order to provide heat to the indoor environment in the next defrosting working state, the phase change energy storage part 3 needs to absorb heat to store heat.

[0082] In one example, controlling the working state of the electromagnetic part at least according to the defrosting state further includes: when the air conditioner exits the defrosting working state, controlling the electromagnetic part to generate a second electromagnetic field; wherein, the second electromagnetic field is an electromagnetic field capable of causing the phase change energy storage part 3 to absorb heat. Specifically, the second electromagnetic field can cause the housing 31 of the phase change energy storage unit to expand. The expansion of the volume reduces the internal pressure of the core 32, and the reduction of the pressure promotes the transformation of the core 32 from the solid state to the liquid state, absorbing the excess heat in the heating process and storing latent heat for the next defrosting process.

[0083] In other realizable manners, the heat absorption of the phase change energy storage unit 3 may not rely on the second magnetic field generated by the electromagnetic unit, and the heat storage can be achieved by the self-absorption of the phase change energy storage unit 3. For example, by using a core 32 made of a phase change material with a phase change temperature close to the user-set temperature, the heat storage can be achieved by the self-absorption of the core 32 when the indoor environmental temperature reaches the set temperature.

[0084] In this embodiment, during the process that the electromagnetic unit needs to generate a magnetic field to make the phase change energy storage unit absorb or release heat, the electromagnetic unit can be controlled to continuously start to generate a magnetic field, or the electromagnetic unit can be controlled to intermittently start to generate a magnetic field. In the case of controlling the electromagnetic unit to intermittently start to generate a magnetic field, after each electromagnetic field application cycle ends, the indoor temperature difference needs to be recalculated, and corresponding control is performed according to the recalculated indoor temperature difference.

[0085] In an optional realizable manner, the working state of the electromagnetic unit is controlled at least according to the indoor temperature, including: controlling the working state of the electromagnetic unit according to the defrosting working state and the indoor temperature difference before and after entering the defrosting working state. In this embodiment, when the air conditioner is still in the defrosting working state, it is necessary to adjust the working state of the electromagnetic unit according to the change of the indoor temperature difference before and after defrosting, so as to avoid the energy waste caused by the excessive phase change of the phase change energy storage unit 3.

[0086] Specifically, controlling the working state of the electromagnetic unit according to the defrosting working state and the indoor temperature difference before and after entering the defrosting working state includes:

[0087] When the air conditioner is in the defrosting working state and the indoor temperature difference is greater than the maximum value of the set temperature range, without external intervention, the indoor temperature difference will continue to increase rapidly on the basis of being greater than the maximum value of the set temperature range, affecting the comfort experience in the heating room. Therefore, in this case, the electromagnetic unit is controlled to generate an electromagnetic field at a first time interval and / or with a first intensity.

[0088] When the air conditioner is in the defrosting working state and the indoor temperature difference is within the set temperature range, at this time, the indoor comfort has been improved compared with that after the electromagnetic field was applied in the previous cycle. Therefore, the electromagnetic field application interval and intensity can be weakened to avoid the energy waste caused by the excessive phase change of the phase change energy storage unit. At this time, the electromagnetic unit is controlled to generate an electromagnetic field at a second time interval and / or with a second intensity, the second interval > the first interval, and the second intensity < the first intensity.

[0089] When the air conditioner is in the defrosting working state and the indoor temperature difference is less than the minimum value of the set temperature range, at this time, the indoor comfort has been maintained in a temperature change range comfortable for the human body compared with that after the electromagnetic field was applied in the previous cycle. At this time, the electromagnetic unit can be controlled to stop generating an electromagnetic field to reduce energy consumption.

[0090] In the above embodiments of the present application, the descriptions of the various embodiments have their own emphases. For the parts not detailed in a certain embodiment, reference may be made to the relevant descriptions of other embodiments. The steps shown in the relevant flowcharts can be executed in a computer system such as a set of computer-executable instructions. And although the logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in a different order than here. In other words, the step order described in the foregoing embodiments is only an example. Based on the content of the embodiments of the present application, a reasonable adjustment of the step order is also within the protection scope of the embodiments of the present application.

[0091] In a specific implementation of the embodiments of the present application, referring to Figure 4 the control flowchart, the control method of the air conditioner includes the following processing procedures:

[0092] The phase change energy storage part 3 is arranged on the air guiding blade 2 of the air outlet assembly, and the electromagnetic part is located on the opposite sides of the air outlet 11 of the air outlet assembly. The phase change energy storage part 3 includes a core 32 and a shell 31 wrapped outside the core 32. The shell 31 is made of a shape memory material with electromagnetic response characteristics (such as magnetic shape memory alloy or electroactive polymer), and the core 32 is made of a solid-liquid phase change material, such as paraffin or its modified material. After absorbing heat, the core 32 changes from solid to liquid, and after releasing heat, the core 32 changes from liquid to solid.

[0093] When the air conditioner operates in the heating mode, use a temperature sensor to detect the frosting condition on the surface of the outdoor heat exchanger and judge whether the air conditioner enters the defrosting working state. When the air conditioner enters the defrosting working state, calculate the indoor temperature difference Δt between the first indoor temperature t0 before entering defrosting and the second indoor temperature t after entering defrosting, and use Δt as the judgment condition for indoor comfort:

[0094] 1) When Δt ≤ 2°C, at this time, the degree of indoor temperature drop is within the temperature range acceptable to the human body sensation, so no additional operation is required;

[0095] 2) When Δt>2℃, if the air conditioner has exited the defrosting working state at this time, it can quickly restore the comfortable temperature in the normal heating mode. However, if the air conditioner is still defrosting at this time, without external intervention, the indoor temperature difference will continue to increase rapidly on the basis of Δt>2℃, affecting the indoor comfort experience. Therefore, in this case, the electromagnetic part placed on the air outlet frame 1 is positively started to apply a positive action to the shell 31 of the phase change energy storage part 3 on the air guide blade 2. At this time, the current direction of the electromagnetic part is the first direction, and the electromagnetic part will generate an electromagnetic field that can shrink the volume of the shell 31 of the phase change energy storage part 3. The shrinkage of the shell 31 increases the pressure on the core 32 material. The increase in pressure promotes the transformation of the core 32 material from liquid to solid, releasing latent heat into the room. The electromagnetic part will generate an electromagnetic field of A1 intensity at the initial start-up, and the interval of the electromagnetic field generation is t1=30s. In the actual operation process, it is also necessary to always detect whether the air conditioner is still in the defrosting working state:

[0096] When the air conditioner exits the defrosting working state, the electromagnetic part will start in the reverse direction. At this time, the current direction of the electromagnetic part is a second direction opposite to the first direction. The electromagnetic part will generate an electromagnetic field that can expand the volume of the shell 31 of the phase change energy storage part 3. The expansion of the shell 31 reduces the internal pressure of the core 32 material. The reduction in pressure promotes the transformation of the core 32 material from solid to liquid, which will absorb the excess heat in the heating process and store latent heat for the next stage of the defrosting process.

[0097] When the air conditioner is still in defrost mode, the time interval and intensity of the electromagnetic field applied by the electromagnetic part need to be adjusted according to the indoor temperature difference Δt;

[0098] a) When 1℃<Δt<2℃, the indoor comfort has been improved after the last magnetic field application cycle, so the electromagnetic field application interval and application intensity can be weakened to avoid energy waste caused by excessive phase change of the phase change energy storage unit 3. At this time, the electromagnetic unit generates an electromagnetic field of A2 intensity, and the generation interval of the electromagnetic field is t2=60s;

[0099] b) When Δt≤1°C, the indoor comfort is maintained in a temperature change range suitable for the human body after the last magnetic field application cycle, so the application of the electromagnetic field can be stopped, and the electromagnetic part stops generating the electromagnetic field.

[0100] In general, this embodiment can effectively reduce the fluctuation of indoor temperature during the defrosting process and high-temperature refrigeration conditions by setting a phase change energy storage unit in the air outlet component, utilizing the heat storage and release functions of the phase change energy storage unit, and combining it with the air conditioning operation control logic, thereby improving the stability of the indoor temperature and further improving the user experience; in addition, the use of the phase change energy storage unit can also optimize the energy distribution during the air conditioning heating process and improve the overall energy efficiency of the air conditioner.
