Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an indoor unit of an air conditioner. Background Technology

[0002] Wall-mounted air conditioners typically consist of two parts: an indoor unit and an outdoor unit. The outdoor unit is usually installed on an exterior wall, balcony, or roof, while the indoor unit is usually installed on an interior wall. The indoor unit draws in air through a heat exchange inlet on its casing, and after the air passes through the indoor heat exchanger, it is released into the room through the heat exchange outlet.

[0003] In related technologies, the heat exchange air outlet of the indoor unit of wall-mounted air conditioners lacks protective components. If a user accidentally touches the high-speed rotating fan, it can cause personal injury. Currently, some wall-mounted air conditioners incorporate protective meshes at the air outlet to protect the fan and prevent user contact. However, some of these protective meshes are currently fixed to the air outlet with screws, while others use additional plastic parts at both ends of a wire mesh, which are then fixed to the air outlet. Both of these wire mesh fixing methods suffer from low assembly efficiency and increased costs due to the addition of extra parts (such as screws or plastic parts). Utility Model Content

[0033] The components include: outer casing 100, air outlet 101, first connecting part 110, first limiting groove 111, second limiting groove 112, guide surface 113, limiting protrusion 114, mounting cover 120, and limiting groove 130.

[0036] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0037] The indoor and outdoor units of an air conditioner are connected by pipes to transfer refrigerant. The indoor unit includes an indoor heat exchanger and a fan assembly (such as a heat exchange fan), while the outdoor unit includes a compressor, a four-way valve, an outdoor heat exchanger, an outdoor fan, and an expansion valve. The compressor, outdoor heat exchanger, expansion valve, and 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 and indoor heat exchangers to achieve the air conditioner's cooling or heating mode.

[0038] An expansion valve connects the outdoor and indoor heat exchangers. The opening degree of the expansion valve regulates the refrigerant pressure flowing through both heat exchangers, thereby regulating the refrigerant flow rate between them. The flow rate and pressure of the refrigerant flowing between the outdoor and indoor heat exchangers affect their heat exchange performance. The expansion valve can be an electronic valve. Its opening degree is adjustable to control the flow rate and pressure of the refrigerant passing through it.

[0039] The outdoor heat exchanger is configured to exchange heat between outdoor air and refrigerant transported within it. For example, in the cooling mode of the air conditioner, the outdoor heat exchanger operates as a condenser, causing the refrigerant compressed by the compressor to dissipate heat to the outdoor air and condense. In the heating mode of the air conditioner, the outdoor heat exchanger operates as an evaporator, causing the depressurized refrigerant to absorb heat from the outdoor air and evaporate.

[0040] In some embodiments, the outdoor heat exchanger further includes heat exchange fins to increase the contact area between the outdoor air and the refrigerant transported in the outdoor heat exchanger, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0041] The air conditioner also includes a control unit. This control unit is configured to control the compressor's operating frequency, the expansion valve's opening degree, the outdoor fan's speed, and the indoor fan's speed. The control unit is connected to the compressor, expansion valve, outdoor fan, and indoor fan assemblies via data cables to transmit communication information.

[0042] The following is for reference. Figures 1-10 The indoor unit 1 of the air conditioner according to an embodiment of the present utility model includes: a housing 100, a fan assembly and an indoor heat exchanger.

[0043] Specifically, the outer casing 100 is provided with an air inlet and an air outlet 101; a fan assembly is disposed inside the outer casing 100; an indoor heat exchanger is disposed inside the outer casing 100, and the fan assembly is used to introduce airflow from outside the outer casing 100 into the outer casing 100 through the air inlet, and to exchange heat through the indoor heat exchanger and output it to the outside through the air outlet 101; it also includes: a protective net 200, which is disposed at the air outlet 101 and fixedly connected to the outer casing 100 and is used to shield the fan assembly; wherein, the outer casing 100 is provided with a first connecting part 110, and the outer periphery of the protective net 200 is provided with a second connecting part 210, and the first connecting part 110 and the second connecting part 210 are connected and fixed to each other to fix the protective net 200 to the outside of the air outlet 101.

[0044] In other words, during the use of the indoor unit 1 of the air conditioner, it is appropriate to construct an air inlet and an air outlet 101 on the outer casing 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 heat exchange is suitable for acting on the indoor environment through the air outlet 101, so that the indoor unit 1 of the air conditioner is suitable for improving the indoor environment and enhancing the user's experience in the indoor environment.

[0045] Furthermore, a fan assembly is suitable for constructing within the outer casing 100 to drive airflow, allowing the airflow to circulate from the air outlet 101 under the drive of the fan. To increase the air outlet 101's airflow efficiency, the air outlet area is made larger. While this results in higher airflow efficiency, it also poses a higher safety hazard. Therefore, a protective net 200 is installed at the air outlet 101. The protective net 200 effectively prevents external debris from entering the interior of the outer casing 100, helps maintain the cleanliness of the interior of the outer casing 100, protects the internal structure from impacts, reduces the impact of foreign objects on the indoor unit 1 of the air conditioner, extends the service life of the indoor unit 1 of the air conditioner, and also prevents users from accidentally inserting their fingers or other objects into the air outlet 101, avoiding injury from accidental contact with the rotating fan assembly inside the outer casing 100. For example, the protective net 200 can be made of wire mesh.

[0046] Specifically, a first connecting part 110 is provided on the outer shell 100, and a second connecting part 210 is provided on the outer periphery of the protective net 200. By connecting the first connecting part 110 and the second connecting part 210, the assembly restriction of the protective net 200 at the air outlet 101 is realized. This allows the protective net 200 to be arranged in the air outlet 101 relatively easily to shield its internal structure, while also avoiding the safety hazard of fingers or other objects being inserted into the air outlet 101.

[0047] According to an embodiment of the present invention, the indoor unit 1 of the air conditioner is equipped with a protective net 200 at the air outlet 101. This net not only prevents debris from entering the interior of the outer casing 100, but also avoids the safety hazard of users inserting their fingers into the indoor unit 1, thus improving the safety of using the indoor unit 1. Furthermore, a first connecting part 110 is provided on the outer casing 100, and a second connecting part 210 is provided on the protective net 200. By connecting the first connecting part 110 and the second connecting part 210, the assembly of the protective net 200 is achieved, simplifying the assembly process, reducing assembly difficulty, and improving assembly efficiency.

[0048] In some embodiments, the protective net 200 includes: a first protective part 201 and a second protective part 202. Multiple first protective parts 201 are arranged horizontally at intervals; multiple second protective parts 202 are arranged vertically at intervals, and the first protective parts 201 and the second protective parts 202 are fixedly connected. Second connecting parts 210 are provided at both ends of the second protective parts 202. Thus, during the construction of the protective net 200, it is suitable to use the first protective parts 201 and the second protective parts 202 to form the protective net 200. Because the first protective parts 201 and the second protective parts 202 are arranged alternately and vertically, they have high structural strength during construction, thereby improving the performance of the protective net 200 and enabling more reliable placement at the air outlet 101 to enhance the reliability of the indoor unit 1 of the air conditioner. Meanwhile, the relatively small gap between the staggered first protective part 201 and the second protective part 202 minimizes the impact on the airflow from the indoor unit 1 of the air conditioner and prevents accidental finger insertion, thus improving the safety of the air conditioner. Furthermore, the fixed connection between the first protective part 201 and the second protective part 202 ensures the high structural performance of the protective net 200, making its construction and use more reliable and thus better protecting the user.

[0049] In some embodiments, the first connecting portion 110 includes: a first limiting groove 111 and a second limiting groove 112. The first limiting groove 111 is disposed on the upper side of the air outlet 101 and is a blind hole; the second limiting groove 112 is disposed on the lower side of the air outlet 101. The second connecting portion 210 includes: a first limiting portion 211 and a second limiting portion 212. The first limiting portion 211 is disposed on the upper part of the first protective portion 201 and is inserted into the first limiting groove 111; the second limiting portion 212 is disposed on the lower part of the first protective portion 201 and is restricted to the second limiting groove 112.

[0050] In other words, in some specific embodiments, the first connecting part 110 is adapted to include a first limiting groove 111 and a second limiting groove 112. The first limiting groove 111 is adapted to be constructed as a blind hole so that the first limiting part 211 in the second connecting part 210 can be constructed in the first limiting groove 111 by plugging in to achieve assembly restriction, so as to simplify the assembly process of the protective net 200. Meanwhile, the second connecting part 210 is also adapted to include a second limiting part 212, which is adapted to limit the first limiting groove 111. This allows the protective net 200 to be assembled at the air outlet 101 by limiting the first limiting part 211 within the first limiting groove 111 and limiting the second limiting part 212 within the second limiting groove 112 during assembly. This simplifies assembly efficiency and ensures that the protective net 200 at the air outlet 101 has high reliability. This allows the protective net 200 to cover the air outlet 101 as designed and effectively prevents accidental insertion of the user's fingers, thereby improving the reliability of the indoor unit 1 of the air conditioner.

[0051] In some embodiments, the second limiting portion 212 extends horizontally; and / or the second limiting groove 112 is formed by a limiting protrusion 114. Thus, by extending the second limiting portion 212 horizontally, a larger contact area is provided for the assembly and restriction of the second limiting portion 212 and the second limiting groove 112, thereby making the assembly of the protective net 200 more reliable and improving the reliability of the indoor unit of the air conditioner. Furthermore, by setting the second limiting groove 112 as a limiting protrusion 114, the assembly of the protective net 200 can be completed by first inserting the first limiting portion 211 into the first limiting groove 111, and then rotating the protective net 200 to restrict the second limiting portion 212 into the second limiting groove 112. This assembly process is relatively simple, improving the production efficiency of the indoor unit 1 of the air conditioner while also making the assembly more reliable. The protective net 200 can better achieve its protective function, reduce safety hazards, and improve the reliability of the indoor unit 1 of the air conditioner.

[0052] In some embodiments, the limiting protrusion 114 is provided with a guide surface 113, which is an inclined surface and tilted towards the air outlet 101. That is, during the construction of the limiting protrusion 114, the guide surface 113 is also suitable. The guide surface 113 is suitable for guiding the assembly process of the protective net 200, so that during assembly, the second limiting part 212 is suitable for being confined within the limiting protrusion 114 by the guide surface 113, making the installation process of the protective net 200 at the air outlet 101 simpler and more reliable. Furthermore, by setting the guide surface 113 as an inclined surface, the second limiting part 212 can be tilted and guided during assembly, allowing the protective net 200 to be assembled via the guide surface 113, 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 can be assembled from the outside to the inside into the limiting protrusion 114 and restricted by the limiting protrusion 114, thereby improving assembly efficiency and reducing assembly difficulty.

[0053] In some embodiments, the protective net 200 further includes a third protective part 203 and a fourth protective part 204. The third protective part 203 is a plurality of horizontally arranged parts and is located 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. In other words, during the construction of the protective net 200, the vertical position is restricted by the first connecting part 110 and the second limiting part 212. The horizontal position restriction of the upper protective net 200 is not obvious. Therefore, a third protective part 203 and a fourth protective part 204 are provided at one end of the protective net 200. 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. During the construction of the protective net 200, the third protective part 203 is suitable to be provided on the side of the air outlet 101 to block the side of the air outlet 101. The fourth protective part 204 is suitable to be constructed on the outside of the third protective part 203, so that the fourth protective part 204 is suitable to vertically connect multiple third protective parts 203. This makes the structure of the third protective part 203 more reliable, so that the third protective part 203 and the fourth protective part 204 can more reliably block the side of the air outlet 101, so as to better prevent the user's finger from accidentally entering and improve safety.

[0054] Furthermore, in the actual construction process, it is appropriate 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 confined 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 indoor unit 1 of the air conditioner.

[0055] In some embodiments, the bottom of the housing 100 is further provided with a mounting cover 120, and the first protective part 201 is provided with a relief groove 205. The relief groove 205 is recessed towards the air outlet 101, and the relief groove 205 is opposite to the mounting cover 120. It is understood that during the assembly process of the housing 100, it is necessary to use methods such as screwing or welding to connect the housing 100 to other structural components. Therefore, a mounting cover 120 can be provided at the bottom of the housing 100. The mounting cover 120 is suitable for covering the outside of the screwed structure to cover and beautify it, and at the same time, it can prevent the airflow from bringing in dust and impurities that come into contact with it and affect its service life. When screwing or removing screws, it is appropriate to open the mounting cover 120. There is a possibility that the mounting cover 120 may collide and interfere with the protective net 200. 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. Without removing the protective net 200, screwing is more difficult and the screwing efficiency is lower. Therefore, an n-shaped structure is suitable for being constructed on the protective net 200 so that a clearance groove 205 can be constructed on the protective net 200. The clearance groove 205 is suitable for being set opposite to the safety cover so that when the safety cover is opened and used, the mounting cover 120 can be rotated into the clearance groove 205 so that the screwing process is easier and the assembly and disassembly efficiency is improved.

[0056] In some embodiments, the inner peripheral wall of the housing 100 is further provided with a limiting groove 130, and the second protective part 202 is limited to the limiting groove 130. It is understood that after the protective net 200 is assembled, it is suitable to limit the second protective part 202 in the protective net 200 to the inner peripheral wall of the housing 100, so as to make the structural arrangement of the second protective part 202 more reliable, thereby correspondingly improving the reliability of the protective net 200 at the air outlet 101.

[0057] In some embodiments, the protective net 200 is a metal protective net 200. It is understood 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 production costs while having better 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 indoor unit 1 of the air conditioner.

[0058] An 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. The housing 100 is provided with an air inlet and an air outlet 101. The fan assembly is disposed inside the housing 100. The indoor heat exchanger is disposed inside the housing 100. The fan assembly is used to introduce airflow from outside the housing 100 into the housing 100 through the air inlet, and to exchange heat through the indoor heat exchanger and output it to the outside through the air outlet 101. It also includes: a protective net 200, which is disposed at the air outlet 101 and fixedly connected to the housing 100 and is used to shield the fan assembly. The protective net 200 includes: a first protective part 201, which consists of multiple horizontally spaced parts; and a second protective part 202, which consists of multiple vertically spaced parts. The first protective part 201 and the second protective part 202 are fixedly connected. The two ends of the second protective part 202 are provided with second connecting parts 210, which are connected to the air outlet 101.

[0059] Specifically, the casing is provided with an air inlet and an air outlet 101, the fan assembly is located inside the casing, and the indoor heat exchanger is located inside the casing. The fan assembly is used to introduce the airflow outside the casing into the casing through the air inlet, and after heat exchange by the indoor heat exchanger, it is output to the outside through the air outlet 101.

[0060] Specifically, airflow flows through the air inlet and air outlet 101 on the casing, realizing air circulation between the indoor airflow and the indoor unit 1 of the air conditioner. The fan assembly can drive the external airflow into the indoor unit 1 of the air conditioner from the air inlet. The indoor heat exchanger exchanges heat with the external airflow entering from the air inlet. The heat exchange airflow formed 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.

[0061] The air inlet is located on the upper side of the casing, and the air outlet 101 is located on the lower front side of the casing. The indoor heat exchanger can be a V-type heat exchanger, a straight plate heat exchanger, etc. The fan assembly contains an indoor fan, which can be a cross-flow fan.

[0062] During the heat exchange process in the indoor heat exchanger, the operation of the fan assembly can increase the wind speed and air volume, thereby increasing the heat transfer efficiency between the airflow and the indoor heat exchanger, resulting in a better user experience.

[0063] Furthermore, a protective net 200 is installed at the air outlet 101 and is connected to the casing. The protective net 200 is used to shield the fan assembly, and the casing provides a stable mounting platform for the protective net 200, thereby improving the installation stability of the protective net 200. The protective net 200 does not affect the flow of heat exchange air at the air outlet 101 and also prevents foreign objects from entering the casing through the air outlet 101, thus improving practicality and safety.

[0064] According to an embodiment of the present invention, the indoor unit 1 of the air conditioner is equipped with a protective net 200 at the air outlet 101. This net not only prevents debris from entering the interior of the outer casing 100, but also avoids the safety hazard of users inserting their fingers into the indoor unit 1, thus improving the safety of using the indoor unit 1. Furthermore, a first connecting part 110 is provided on the outer casing 100, and a second connecting part 210 is provided on the protective net 200. By connecting the first connecting part 110 and the second connecting part 210, the assembly of the protective net 200 is achieved, simplifying the assembly process, reducing assembly difficulty, and improving assembly efficiency.
