DETAILED DESCRIPTION

[0019] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0020] The indoor unit and the outdoor unit of the air conditioner are connected by pipelines to transmit refrigerant. The indoor unit of the air conditioner includes an indoor heat exchanger and a fan assembly (such as a heat exchange fan), and the outdoor unit of the air conditioner includes a compressor, a four-way valve, an outdoor heat exchanger, an outdoor fan and an expansion valve. The compressor, the outdoor heat exchanger, the expansion valve and the indoor heat exchanger connected in sequence form a refrigerant circuit. The refrigerant circulates in the refrigerant circuit and exchanges heat with the air through the outdoor heat exchanger and the indoor heat exchanger respectively to realize the cooling mode or heating mode of the air conditioner.

[0021] The expansion valve is connected between the outdoor heat exchanger and the indoor heat exchanger. The opening of the expansion valve adjusts the pressure of the refrigerant flowing through the outdoor heat exchanger and the indoor heat exchanger to adjust the flow of the refrigerant flowing between the outdoor heat exchanger and the indoor heat exchanger. The flow and pressure of the refrigerant flowing between the outdoor heat exchanger and the indoor heat exchanger will affect the heat exchange performance of the outdoor heat exchanger and the indoor heat exchanger. The expansion valve can be an electronic valve. The opening of the expansion valve is adjustable to control the flow and pressure of the refrigerant flowing through the expansion valve.

[0022] The outdoor heat exchanger is configured to perform heat exchange between outdoor air and the refrigerant transmitted in the outdoor heat exchanger. For example, the outdoor heat exchanger works as a condenser in the cooling mode of the air conditioner, so that the refrigerant compressed by the compressor condenses by dissipating heat to the outdoor air through the outdoor heat exchanger. The outdoor heat exchanger works as an evaporator in the heating mode of the air conditioner, so that the decompressed refrigerant absorbs the heat of the outdoor air through the outdoor heat exchanger and evaporates.

[0023] In some embodiments, the outdoor heat exchanger further includes heat exchange fins to expand the contact area between the outdoor air and the refrigerant transmitted in the outdoor heat exchanger, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0024] The air conditioner also includes a control device. The control device is configured to control the operating frequency of the compressor, the opening of the expansion valve, the rotation speed of the outdoor fan and the rotation speed of the indoor fan. The control device is connected to the compressor, the expansion valve, the outdoor fan and the indoor fan assembly through a data line to transmit communication information.

[0025] Reference below Figure 1-Figure 10 The indoor unit 1 of an air conditioner according to an embodiment of the present invention includes a housing 100 , a fan assembly and an indoor heat exchanger.

[0026] Specifically, the shell 100 is provided with an air inlet and an air outlet 101; the fan assembly is arranged in the shell 100; the indoor heat exchanger is arranged in the shell 100, and the fan assembly is used to introduce the airflow outside the shell 100 from the air inlet into the shell 100, and output it to the outside through the air outlet 101 through heat exchange in the indoor heat exchanger; it also includes: a protective net 200, the protective net 200 is arranged at the air outlet 101 and is fixedly connected to the shell 100 and is used to shield the fan assembly; wherein, the shell 100 is provided with a first connecting portion 110, and the two ends of the protective net 200 in the vertical direction are provided with second connecting portions 210, and the first connecting portion 110 and the second connecting portion 210 are mutually connected and fixed to fix the protective net 200 on the outside of the air outlet 101.

[0027] That is to say, during the use of the air conditioner indoor unit 1, it is suitable to construct an air inlet and an air outlet 101 on the outer shell 100, so that the air inlet is suitable for introducing outdoor airflow, and the outdoor airflow exchanges heat on the heat exchanger in the heat exchange room, so that the airflow after the heat exchange is suitable for acting on the indoor environment through the air outlet 101, so that the air conditioner indoor unit 1 is suitable for improving the indoor environment, so as to enhance the user experience in the indoor environment.

[0028] Moreover, a fan assembly is suitable for driving the airflow to circulate in the housing 100, so that the airflow can circulate from the air outlet 101 under the drive of the fan. In order to make the air outlet efficiency of the air outlet 101 higher, the air outlet area of ​​the air outlet 101 will be made larger. In this way, although the air outlet efficiency is high, it has a high safety hazard. Therefore, a protective net 200 is provided at the air outlet 101. The protective net 200 is provided at the air outlet 101 to effectively prevent external debris from entering the interior of the housing 100, which helps to maintain the cleanliness of the interior of the housing 100 and protect the internal structure of the housing 100 from collision, reduce the impact of external foreign matter on the indoor unit 1 of the air conditioner, extend the service life of the indoor unit 1 of the air conditioner, and prevent users from accidentally inserting their fingers or other objects into the air outlet 101 of the air conditioner, so as to avoid users from being injured by accidentally touching the rotating fan assembly in the housing 100. For example, the protective net 200 can be a wire mesh.

[0029] Specifically, a first connecting portion 110 is provided on the outer shell 100, and a second connecting portion 210 is provided on the outer peripheral side of the protective net 200. The first connecting portion 110 is connected to the second connecting portion 210 to achieve the assembly restriction of the protective net 200 at the air outlet 101, so that the protective net 200 can be arranged at the air outlet 101 more simply to shield its internal structure, while avoiding the safety hazard of fingers or other objects being inserted into the air outlet 101.

[0030] According to the air conditioner indoor unit 1 of the embodiment of the present invention, a protective net 200 is provided at the air outlet 101, so that the protective net 200 can block the sundries from entering the interior of the housing 100, and can also avoid the potential safety hazard of the user's fingers inserting into the air conditioner indoor unit 1, so that the safety of the use of the air conditioner indoor unit 1 is improved. In addition, a first connecting portion 110 is provided on the housing 100, and a second connecting portion 210 is provided on the protective net 200. By restricting the connection between the first connecting portion 110 and the second connecting portion 210, the protective net 200 can be assembled at the air outlet, which simplifies the assembly process and reduces the difficulty of assembly, thereby improving the assembly efficiency.

[0031] In some embodiments, the protective net 200 includes: a first protective part 201 and a second protective part 202, wherein the first protective part 201 is a plurality of horizontally spaced parts; the second protective part 202 is a plurality of vertically spaced parts, and the first protective part 201 and the second protective part 202 are fixedly connected, and the second connecting parts 210 are provided at both ends of the second protective part 202. In this way, in the process of constructing the protective net 200, it is suitable to use the first protective part 201 and the second protective part 202 to form the protective net 200. Since the first protective part 201 and the second protective part 202 are staggered and vertically arranged, the first protective part 201 and the second protective part 202 have a higher structural strength when being constructed, so that the use performance of the protective net 200 is improved, and the air outlet 101 can be arranged more reliably to improve the reliability of the use of the air conditioner indoor unit 1. At the same time, the gap formed between the first protective part 201 and the second protective part 202, which are arranged at staggered intervals, is relatively small, which has a relatively small impact on the air outlet of the air conditioner indoor unit 1 and can also prevent the user's fingers from entering by mistake, thereby improving the safety of the air conditioner. At the same time, the first protective part 201 and the second protective part 202 are fixedly connected to make the structure of the protective net 200 have higher structural performance, so that the construction and use of the protective net 200 are more reliable, thereby better realizing the protection effect for the user.

[0032] In some embodiments, the first connection portion 110 includes: a first limiting groove 111 and a second limiting groove 112, the first limiting groove 111 is arranged on the upper side of the air outlet 101, and the first limiting groove 111 is a blind hole; the second limiting groove 112 is arranged on the lower side of the air outlet 101; the second connection portion 210 includes: a first limiting portion 211 and a second limiting portion 212, the first limiting portion 211 is arranged on the upper part of the first protective portion 201, and the first limiting portion 211 is plugged into the first limiting groove 111; the second limiting portion 212 is arranged on the lower part of the first protective portion 201, and the second limiting portion 212 is limited to the second limiting groove 112.

[0033] That is to say, in some specific embodiments, the first connecting portion 110 is suitable for including a first limiting groove 111 and a second limiting groove 112, and the first limiting groove 111 is suitable for being constructed as a blind hole, so that the first limiting portion 211 in the second connecting portion 210 can be constructed in the first limiting groove 111 by plugging to achieve assembly restriction, so that the assembly process of the protective net 200 is simplified. At the same time, the second connecting portion 210 is also suitable for including a second limiting portion 212, and the second limiting portion 212 is suitable for being limited with the first limiting groove 111, so that during the assembly process of the protective net 200, it is suitable for limiting the first limiting portion 211 within the first limiting groove 111 and limiting the second limiting portion 212 in the second limiting groove 112 to realize the assembly of the protective net 200 at the air outlet 101. While simplifying the assembly efficiency, it can also make the construction of the protective net 200 at the air outlet 101 have higher reliability, so that the protective net 200 can block the air outlet 101 as designed, and can better avoid the user's fingers from accidentally entering, so as to improve the reliability of the air conditioner indoor unit 1.

[0034] In some embodiments, the second limiting portion 212 extends in the horizontal direction; and / or the second limiting groove 112 is formed by a limiting protrusion 114. In this way, the extension direction of the second limiting portion 212 is extended horizontally, so that the second limiting portion 212 and the second limiting groove 112 have a larger contact area for limiting, so that the assembly construction of the protection net 200 is more reliable, so that the reliability of use in the air conditioner is improved. In addition, the second limiting groove 112 is set as a limiting protrusion 114, so that during the construction process of the protection net 200, the first limiting portion 211 is first plugged into the first limiting groove 111, and then the protection net 200 is rotated to allow the second limiting portion 212 and the second limiting groove 112 to limit to complete the assembly. The assembly process is relatively simple, and the production efficiency of the air conditioner indoor unit 1 is improved while the assembly can be made more reliable. The protection net 200 can better achieve the protective effect, reduce safety hazards, and improve the reliability of use of the air conditioner indoor unit 1.

[0035] In some embodiments, the limiting protrusion 114 is provided with a guide surface 113, which is an inclined surface and is inclined toward the air outlet 101. That is to say, during the construction process of the limiting protrusion 114, it is also suitable to be provided with a guide surface 113, and the guide surface 113 is suitable for guiding the assembly process of the protective net 200, so that when the protective net 200 is assembled, the second limiting portion 212 is suitable for being limited in the limiting protrusion 114 through the guide surface 113, so that the setting process of the protective net 200 at the air outlet 101 is simpler and the restriction is more reliable. In addition, the guide surface 113 is set as an inclined surface so that the second limiting portion 212 can be inclined and guided by the guide inclined surface during the assembly process, so that the protective net 200 can be assembled through the guide surface 113 during the assembly process, thereby making the assembly of the protective net 200 simpler and more reliable. In addition, it is also suitable to tilt the inclined surface toward the air outlet 101, so that the protective net 200 is assembled from the outside to the inside of the limiting protrusion 114 and is restricted by the limiting protrusion 114, thereby improving the assembly efficiency and reducing the difficulty of assembly.

[0036] In some embodiments, the protective net 200 also includes: a third protective part 203 and a fourth protective part 204, the third protective part 203 is horizontally arranged in multiple pieces and the third protective part 203 is arranged at one end of the first protective part 201; the fourth protective part 204 is vertically connected to the free end of the third protective part 203. That is to say, during the construction of the protective net 200, it is suitable to limit the position in the vertical direction through the first connecting part 110 and the second limiting part 212, and the position restriction of the upper protective net 200 in the horizontal direction is not obvious. Therefore, a third protective part 203 and a fourth protective part 204 are also provided at one end of the protective net 200, and the third protective part 203 is suitable to be constructed at one end of the first protective part 201, so that the free end of the third protective part 203 is suitable to be constructed with the fourth protective part 204, so that during the construction of the protective net 200, it is suitable to provide the third protective part 203 on the side of the air outlet 101 to block the side of the air outlet 101, and the fourth protective part 204 is suitable to be constructed on the outer side of the third protective part 203, so that the fourth protective part 204 is suitable for vertically connecting multiple third protective parts 203, so that the structural construction of the third protective part 203 is more reliable, so that the third protective part 203 and the fourth protective part 204 can be more reliably blocked on the side of the air outlet 101, so as to better avoid the user's fingers from entering by mistake and improve safety.

[0037] Moreover, in the actual construction process, it is suitable to make the extension direction of the third protective part 203 perpendicular to the extension direction of the first protective part 201, so that the third protective part 203 can be more reliably restricted to the side of the air outlet 101, thereby making the use of the protective net 200 safer and avoiding safety hazards during the use of the air conditioner indoor unit 1.

[0038] In some embodiments, the bottom of the housing 100 is further provided with a mounting cover 120, and the first protective portion 201 is provided with an avoidance groove 205, which is recessed toward the air outlet 101, and the avoidance groove 205 is arranged opposite to the mounting cover 120. It is understandable that during the assembly process of the housing 100, the housing 100 needs to be connected to other structural parts by means such as screwing or welding. Therefore, a mounting cover 120 can be correspondingly arranged at the bottom of the housing 100, and the mounting cover 120 is suitable for shielding the outside of the screwing structure to shield and beautify it, and at the same time, it can also prevent the airflow from bringing in dust and impurities to contact with it to affect the service life. In the process of screwing or removing the screwing, it is suitable to open the mounting cover 120, and there may be a situation where the mounting cover 120 and the protective net 200 interfere with each other, and if the position of the mounting cover 120 and the protective net 200 is too close, it will also affect the screwing process and screwing efficiency. In the case of not removing the protective net 200, the screwing difficulty is greater and the screwing efficiency is low. Therefore, it is suitable to construct an n-type structure on the protective net 200 so that an avoidance groove 205 can be constructed on the protective net 200. The avoidance groove 205 is suitable to be arranged opposite to the safety cover so that when the safety cover is opened and used, it is suitable to rotate the installation cover 120 into the avoidance groove 205, so as to make the screw connection process easier and improve the assembly and disassembly efficiency.

[0039] In some embodiments, the inner circumferential wall of the housing 100 is further provided with a limiting groove 130, and the second protection part 202 is limited to the limiting groove 130. It is understandable that after the assembly of the protection net 200 is completed, it is suitable to limit the second protection part 202 in the protection net 200 to the inner circumferential wall of the housing 100, so that the structural arrangement of the second protection part 202 is more reliable, thereby correspondingly improving the reliability of the protection net 200 at the air outlet 101.

[0040] In some embodiments, the protective net 200 is a metal protective net 200. It is understandable that in the production process of the specific protective net 200, the protective net 200 can be set as a metal protective net 200, so that the protective net 200 can reduce the production cost while having a relatively good structural performance so that the protective net 200 can be more reliably arranged at the air outlet 101 to shield and protect the air outlet 101, thereby improving the safety of using the air conditioner indoor unit 1.

[0041] According to an embodiment of the present invention, the indoor unit 1 of the air conditioner comprises: a housing 100, a fan assembly and an indoor heat exchanger, wherein the housing 100 is provided with an air inlet and an air outlet 101; the fan assembly is arranged in the housing 100; the indoor heat exchanger is arranged in the housing 100, and the fan assembly is used to introduce the airflow outside the housing 100 into the housing 100 from the air inlet, and output it to the outside through the air outlet 101 through heat exchange in the indoor heat exchanger; and further comprises: a protective net 200, which is arranged at the air outlet 101 and fixedly connected to the housing 100 and used to shield the fan assembly; wherein the protective net 200 comprises: a first protective part 201, which is a plurality of the first protective parts 201 arranged at horizontal intervals; a second protective part 202, which is a plurality of the second protective parts 202 arranged at vertical intervals, and the first protective part 201 and the second protective part 202 are fixedly connected, and second connecting parts 210 are arranged at both ends of the second protective part 202, and the second connecting part 210 is connected to the air outlet 101.

[0042] Specifically, the casing is provided with an air inlet and an air outlet 101, the fan assembly is arranged in the casing, the indoor heat exchanger is arranged in the casing, and the fan assembly is used to introduce the airflow outside the casing into the casing from the air inlet, and output it to the outside through the air outlet 101 after heat exchange in the indoor heat exchanger.

[0043] Specifically, the air flow flows through the air inlet and the air outlet 101 on the casing to realize air circulation between the indoor air flow and the indoor unit 1 of the air conditioner. The fan assembly can drive the external air flow to enter the indoor unit 1 of the air conditioner from the air inlet. The indoor heat exchanger exchanges heat with the external air flow entering from the air inlet. The formed heat exchange air flow is then blown into the room from the air outlet 101 under the drive of the fan assembly, thereby achieving the effect of regulating the indoor temperature.

[0044] Among them, the air inlet is located on the upper side of the casing, the air outlet 101 is arranged at the lower front side of the casing, the indoor heat exchanger can be a V-shaped heat exchanger, a straight plate heat exchanger, etc., and the fan assembly is provided with an indoor fan, which can be a cross-flow fan.

[0046] Furthermore, the protective net 200 is disposed at the air outlet 101, and the protective net 200 is connected to the housing, and the protective net 200 is used to shield the fan assembly, and the housing can provide a stable installation carrier for the protective net 200, thereby improving the installation stability of the protective net 200. Among them, the protective net 200 will not affect the circulation effect of the heat exchange airflow at the air outlet 101, and can also prevent foreign objects from entering the housing through the air outlet 101, thereby improving practicality and safety.

[0047] According to the air conditioner indoor unit 1 of the embodiment of the present invention, a protective net 200 is provided at the air outlet 101, so that the protective net 200 can block the sundries from entering the interior of the housing 100, and can also avoid the potential safety hazard of the user's fingers inserting into the air conditioner indoor unit 1, so that the safety of the use of the air conditioner indoor unit 1 is improved. In addition, a first connecting portion 110 is provided on the housing 100, and a second connecting portion 210 is provided on the protective net 200. By connecting the first connecting portion 110 and the second connecting portion 210 to realize the assembly of the protective net 200, the assembly process can be simplified, the assembly difficulty can be reduced, and the assembly efficiency can be improved.
