[0042] At present, the heating capacity of air conditioners is insufficient during the heating process, and electric auxiliary heating devices are usually added to the indoor unit for auxiliary heating. The electric auxiliary heating devices are mostly installed in the evaporator cavity, but this will disturb the wind field in the cavity, resulting in poor heat exchange effect of the evaporator.

[0043] The related technology provides an air conditioner with an auxiliary heating function, which uses a sheet-shaped heating element, and the heating element is arranged between the evaporator and the back plate of the shell. The heating element and the evaporator are kept at a certain distance, which effectively reduces the obstruction of the air flow in the air conditioner and makes the air flow inside the air conditioner smoother.

[0044] Combination Figure 1-3 As shown, an embodiment of the present disclosure provides an air-conditioning indoor unit, including a housing 10 , a fan 20 , a heat exchanger 30 and a heating element 40 .

[0045] The shell 10 is provided with an air outlet 11; the fan 20 is arranged in the shell 10; the heat exchanger 30 is arranged in the shell 10, and the heat exchanger 30 is located between the fan 20 and the air outlet 11; the heating element 40 is arranged in the shell 10 and located at the air outlet 11, and the heating element 40 is arranged corresponding to the heat exchanger 30; wherein, along the air outlet direction, the fan 20, the heat exchanger 30 and the heating element 40 are arranged in sequence.

[0046] Air outlet direction Figure 1 shown.

[0047] The indoor unit of the air conditioner provided by the embodiment of the present disclosure is adopted, and the heating element 40 is arranged in the housing 10 near the air outlet 11, corresponding to the heat exchanger 30. Such a layout enables the heating element 40 to directly assist in heating the airflow passing through the heat exchanger 30, optimizes the air duct design, and thus improves the heating effect and efficiency. The air flowing into the housing 10 is driven by the fan 20 to flow toward the heat exchanger 30. After the airflow passes through the heat exchanger 30 for heat exchange with the refrigerant, it is supplemented by the heating element 40 so that the airflow can reach the required temperature before flowing out of the air outlet 11. After continuous heat exchange and heating processes, the loss of heat in the transfer process can be reduced, so that the thermal interaction of the airflow can be more compact and efficient. At the same time, the heating element 40 is arranged between the heat exchanger 30 and the air outlet 11, which can also avoid disturbing the wind field in the cavity of the heat exchanger 30 and improve the heat exchange effect of the heat exchanger 30.

[0048] Optionally, combined Figure 1-3As shown, a first end of the heating element 40 is connected to the inner wall of the housing 10 or the heat exchanger 30 , and a second end of the heating element 40 extends toward the air outlet 11 .

[0049] The first end of the heating element 40 is connected to the inner wall of the housing 10 or the heat exchanger 30, providing a stable fixing point, which can improve the stability of the heating element 40, thereby reducing the vibration generated when the air conditioner is running and reducing noise. The second end extends toward the air outlet 11, so that the heating element 40 forms a guide surface, which can more directly and effectively guide the airflow out of the heat exchanger 30 to the air outlet 11. At the same time, the second end of the heating element 40 extends toward the air outlet 11, which can also increase the contact area and contact time between the heating element 40 and the airflow out of the heat exchanger 30, thereby improving the auxiliary heating efficiency.

[0050] Optionally, combined Figure 1 As shown, the second end of the heating element 40 is connected to the inner wall of the housing 10 at the air outlet 11 , and the second end of the heating element 40 extends along the inner wall of the air outlet 11 .

[0051] The connection between the second end of the heating element 40 and the inner wall of the housing 10 forms a support point, which enhances the stability of the heating element 40. The second end of the heating element 40 is set according to the shape of the air outlet 11, and the extension along the inner wall of the air outlet 11 can increase the contact area with the airflow, thereby improving the heat exchange efficiency and allowing the air to be heated more effectively before being discharged from the air outlet. The extended portion of the heating element 40 can also serve as a natural deflector for the airflow, guiding the airflow to flow more smoothly through the heating area and reducing the airflow resistance. At the same time, the second end of the heating element 40 extends along the inner wall of the air outlet 11, which can also reduce the turbulence of the airflow at the air outlet 11, thereby reducing noise.

[0052] Optionally, combined Figure 1 As shown, the heating element 40 is inclined toward the air outlet 11 , and the angle formed between the heating element 40 and the inner wall of the housing 10 is an acute angle.

[0053] The angle formed between the heating element 40 and the inner wall of the housing 10 is as follows: Figure 1 As shown in α.

[0054] The heating element 40 is tilted toward the air outlet 11, and the angle formed with the inner wall of the housing 10 is an acute angle, which can make the heating element 40 closer to the airflow, improve the heat exchange efficiency, and allow the air to be heated faster before being discharged. The angle formed between the heating element 40 and the inner wall of the housing 10 can also change the straight-line flow direction of the airflow, causing the airflow to deflect when passing through the heating element 40, disturbing the wind field, and promoting the air flowing out of the heat exchanger 30 to mix more fully with the heat on the surface of the heating element 40, thereby improving the heating uniformity.

[0055] Optionally, a drain outlet is provided on the bottom wall of the shell 10, and the heating element 40 is provided on the bottom wall of the shell 10, and a first end of the heating element 40 extends obliquely toward the drain outlet.

[0056] The first end of the heating element 40 extends obliquely toward the drain outlet, so that a slope is formed between the heating element 40 and the bottom wall of the shell 10. During cooling, the inclined surface of the heating element 40 can guide the condensed water to be discharged to avoid water accumulation.

[0057] Optionally, combined Figure 2 As shown, the heating element 40 extends along the inner wall of the housing 10 toward the air outlet 11 .

[0058] The heating element 40 is arranged according to the shape of the inner wall of the shell 10 and extends along the inner wall of the shell 10 toward the air outlet 11. The heating element 40 can fit the inner wall of the shell 10, which can increase the contact area between the airflow and the heating element 40, reduce air resistance, and make the airflow flow smoothly on the heating element 40, thereby reducing turbulence and noise.

[0059] Optionally, combined Figure 3 As shown, the heating element 40 includes a first section 41 and a second section 42, the first section 41 is connected to the inner wall of the shell 10 or the heat exchanger 30; the second section 42 is connected to the inner wall of the air outlet 11; wherein the first section 41 and the second section 42 are connected and form a bend away from the inner wall of the shell 10.

[0060] The first section 41 and the second section 42 of the heating element 40 form a bent structure away from the inner wall of the housing 10, which can disturb the wind field, increase the contact points between the heating element 40 and the air flow path, improve the contact efficiency between the air and the heating surface, make the air flow more uniformly heated, and thus improve the heating effect. At the same time, the bending structure of the heating element 40 can also increase the length of the heating element 40 within a limited space, achieve a more compact layout, improve the space utilization rate within the housing 10, and increase the contact area between the air flow and the heating element 40.

[0061] Optionally, combined Figure 1-3 As shown, the air outlet 11 includes a first air outlet end 111 and a second air outlet end 112 which are radially opposite to each other, and the heating element 40 includes a first heating plate 43 and a second heating plate 44. The first heating plate 43 is arranged corresponding to the first end of the heat exchanger 30 along the length direction and extends toward the first air outlet end 111; the second heating plate 44 is arranged corresponding to the second end of the heat exchanger 30 along the length direction and extends toward the second air outlet end 112.

[0062] The length direction of the heat exchanger 30 is as follows Figure 3As shown. The first heating plate 43 and the second heating plate 44 are respectively arranged corresponding to the first outlet end 111 and the second outlet end 112 of the outlet 11, so that the heat energy of the heating element 40 is evenly distributed in the entire outlet 11 area. The first heating plate 43 and the second heating plate 44 form a symmetrical heating area along the radial direction of the outlet 11, which can effectively heat the airflow flowing to the outlet 11, thereby improving the heating uniformity and heating efficiency.

[0063] Optionally, combined Figure 1-3 As shown, the heat exchanger 30 is arranged tilted relative to the air outlet 11 .

[0064] The heat exchanger 30 is tilted relative to the air outlet 11, so that the air outlet side of the heat exchanger 30 can be prevented from directly facing the air outlet 11. In this way, after the airflow leaves the heat exchanger 30, the airflow can be retained in the housing 10 for a longer time, thereby increasing the contact time between the airflow and the heating element 40, so that the air reaches a more uniform temperature before being discharged, and the auxiliary heating effect of the heating element 40 on the airflow is improved.

[0065] Optionally, the air outlet side of the heat exchanger 30 is arranged toward the heating element 40 .

[0066] The air outlet side of the heat exchanger 30 is arranged toward the heating element 40 , so that the air can be heated by the heating element 40 more quickly after leaving the heat exchanger 30 , thereby improving the heat exchange efficiency between the heat exchanger 30 and the heating element 40 .

[0067] Optionally, combined Figure 4-5 As shown, the surface of the heating element 40 facing away from the inner wall of the shell 10 is provided with one or more air guide grooves 45, and the air guide grooves 45 extend toward the air outlet 11; when there are multiple air guide grooves 45, the multiple air guide grooves 45 are arranged in sequence along the width direction of the heating element 40.

[0068] The width direction of the heating element 40 is as follows Figure 4-5 As shown. The heating element 40 is provided with one or more air guide grooves 45, which are arranged on the surface away from the inner wall of the shell 10 and extend toward the air outlet 11, so as to guide the airflow to flow through the heating element 40 more smoothly. At the same time, it can also increase the surface area of ​​the airflow in contact with the heating element 40, thereby improving the heat exchange efficiency. When there are multiple air guide grooves 45, the multiple air guide grooves 45 are distributed along the width direction of the heating element 40, which increases the flow channel of the airflow on the surface of the heating element 40, can improve the uniformity of the airflow flow, and avoid the airflow from being retained in a local area on the surface of the heating element 40. At the same time, the airflow is evenly distributed on the surface of the heating element 40 through the multiple air guide grooves 45, which can also improve the heating efficiency of the heating element 40.

[0069] Optionally, combined Figure 4As shown, the air guide groove 45 includes an air guide convex groove, and the surface of the heating element 40 facing away from the inner wall of the shell 10 is provided with multiple air guide protrusions 451 extending toward the air outlet 11, and the multiple air guide protrusions 451 are arranged in sequence along the width direction of the heating element 40, and air guide convex grooves are formed between adjacent air guide protrusions 451.

[0070] A plurality of air guide protrusions 451 are provided on the surface of the heating element 40 away from the inner wall of the housing 10. The plurality of air guide protrusions 451 extend toward the air outlet 11 and are distributed along the width direction of the heating element 40, and can form a plurality of air guide convex grooves extending toward the air outlet 11 and distributed along the width direction of the heating element 40. The air guide convex grooves can guide the airflow to the air outlet 11, thereby enhancing the stability of the air flow. The air guide protrusions 451 extend toward the air outlet 11, and can also increase the surface area of ​​the airflow in contact with the heating element 40, thereby improving the heat exchange efficiency.

[0071] Optionally, the air guiding slot 45 includes an air guiding groove extending toward the air outlet 11 .

[0072] The air guide groove is a structure sunken in the surface of the heating element 40, which guides the air flow by forming an air flow channel. The air guide groove can increase the surface area of ​​the air flow in contact with the heating element 40, thereby improving the heat exchange efficiency.

[0073] Optionally, combined Figure 6 As shown, the heating element 40 includes a heating layer 46 and a substrate layer 47. The heating layer 46 is arranged on the side of the heating element 40 facing away from the inner wall of the shell 10 to heat the airflow; the substrate layer 47 is arranged on the side of the heating element 40 facing the inner wall of the shell 10 and is connected to the heating layer 46 to support the heating layer 46.

[0074] The heating layer 46 can heat up quickly and transfer heat to the airflow evenly. The substrate layer 47 provides necessary mechanical support for the heating layer 46, so that the heating layer 46 remains stable under high temperature and airflow impact, thereby improving the structural stability of the heating element 40.

[0075] Optionally, the heating layer 46 and the substrate layer 47 both extend toward the air outlet 11 .

[0076] The base material layer 47 extends toward the air outlet 11 to guide the airflow. The heating layer 46 extends toward the air outlet 11 to effectively heat the airflow flowing from the heat exchanger 30 to the air outlet.

[0077] Optionally, combined Figure 6As shown, the heating element 40 is a thick film heating plate, and the heating layer 46 includes a covering layer 461, a resistor layer 462 and a conductor layer 463; the thick film heating plate also includes an insulating layer 48, and the insulating layer 48 is arranged between the substrate layer 47 and the heating layer 46; wherein, along the thickness direction of the heating element 40, the covering layer 461, the resistor layer 462, the conductor layer 463, the insulating layer 48 and the substrate layer 47 are arranged in sequence, the substrate layer 47 is arranged on the side of the thick film heating plate facing the inner wall of the shell 10, and the covering layer 461 is arranged on the side of the thick film heating plate away from the inner wall of the shell 10.

[0078] The thickness direction of the heating element 40 is as follows Figure 6 As shown. The thick film heating plate can improve the heating efficiency and safety. The covering layer 461 is arranged on the side of the thick film heating plate away from the inner wall of the shell 10, in direct contact with the air, and can protect the other bottom layers of the heating element 40. The resistance layer 462 is coated with a resistance slurry and can generate heat after power is turned on. The conductor layer 463 plays a conductive role and can conduct electricity to the resistance layer 462. The substrate layer 47 is arranged on the side of the thick film heating plate facing the inner wall of the shell 10, and supports the heating element 40. The substrate layer 47 can be made of stainless steel or alloy steel to provide the necessary mechanical strength and durability, and improve the stability of the heating element 40. The insulating layer 48 is arranged between the substrate layer 47 and the heating layer 46, which can prevent the substrate layer 47 from conducting electricity, thereby preventing the heating element 40 from conducting electricity with the shell 10, and improving the safety of the heating element 40.

[0081] When the sensor feedback indicates that the indoor temperature is too low, the controller controls the air conditioner to increase the load, and the airflow exchanges heat with the refrigerant through the heat exchanger 30. When the air conditioner reaches the maximum load and the temperature is still too low, the controller controls the heating element 40 to be powered on, and after the airflow exchanges heat with the refrigerant through the heat exchanger 30, the heating element 40 performs auxiliary heating on the airflow. When the sensor feedback indicates that the temperature reaches the standard, the controller controls the heating element 40 to be powered off and the air conditioner is unloaded. In this way, the load can be automatically unloaded when the temperature reaches the standard, thereby achieving energy saving.
