Technical Field

The invention relates to an air conditioner, in particular to an indoor hanging unit of an air conditioner.

Background technique

With the popularity of air conditioners, users have higher and higher requirements for the comfort and health of air supply. Traditional air conditioners have strong air supply, and the cold air blows directly on people. Air-conditioning disease is the biggest problem for users to use air conditioners. Through the continuous innovation of air conditioning technology, jet technology and drainage technology have emerged, bringing the concept of healthy air supply that is cool but not cold. However, these technologies still have certain limitations. The biggest problem is uneven mixed flow, which affects the user's comfort experience.

Traditional drainage or jet solutions lack a mixing flow structure at the air outlet and the drainage or jet port, so the cold air blown out by the air conditioner is not completely mixed with the indoor air before it blows directly to the user, failing to achieve the ideal cool but not cold effect.

Detailed ways

Air conditioners generally draw indoor air in from the air inlet of the indoor unit, and after heat exchange in the heat exchanger, the heated gas is blown out from the air outlet of the indoor unit again, repeating this cycle, continuously exchanging heat for the indoor gas to maintain a comfortable temperature for the indoor air.

FIG. 1 is an indoor air conditioner unit 10 according to an embodiment of the present invention, and FIG. 2 is a schematic side sectional view of the indoor air conditioner 10 shown in FIG. 1 ; the indoor air conditioner 10 includes an air conditioner body 100 and an air supply mixed flow assembly 200 .

Among them, those skilled in the art can understand that the function of the hook body 100 provided by the present invention is the same as the function of a separate indoor hook in the prior art, that is, a heat exchanger 130 is arranged in the hook body 100, and the indoor gas enters from the main air inlet 110 of the hook body 100, and after heat exchange by the heat exchanger 130, it is blown out from the main air supply port 120 of the hook body 100 to the room, and circulates to exchange heat for the indoor air.

Furthermore, a main crossflow fan 140 is provided at the heat exchanger 130 facing the main air supply outlet 120, and a main volute is provided on the outside of the main crossflow fan 140, and the above-mentioned main air supply outlet 120 is provided at the lower part. The main crossflow fan 140 is used to introduce indoor air from the main air inlet 110 into the main air duct inner diameter heat exchanger 130 for heat exchange and then send it to the main air supply outlet 120 for output.

In this embodiment, specifically, Figure 3 is a schematic diagram of the air flow direction of the indoor hanging machine 10 shown in Figure 2. When the mixed flow air inlet 221 is facing the upper rear side of the hanging machine body 100, the air flow of the mixed flow air inlet 221 is entirely from the indoor air; the mixed flow air outlet 222 is facing the upper front side of the hanging machine body 100, so that the air flow of the mixed flow air outlet 222 is entirely blown toward the air outlet direction of the main air supply port 120.

Furthermore, the mixed flow outlet 222 is completely located on the side of the vertical plane where the lowest point of the main air supply outlet 120 is located, facing the indoor room. When the airflow outlet direction of the mixed flow outlet 222 is perpendicular to the heat exchange air outlet direction of the main air supply outlet 120, the air from the mixed flow outlet 222 is all blown toward the main air supply outlet 120, breaking up the heat exchange air of the main air supply outlet 120, and making the heat exchange air and indoor air fully mixed. The hot and cold airflows in different directions are dispersed and mixed with each other, and the airflow direction changes randomly, eventually forming a soft natural wind that is cool but not cold, thereby improving the user experience.

In particular, there is a spacing distance between the horizontal plane where the highest point of the mixed flow outlet 222 is located and the horizontal plane where the lowest point of the main air supply outlet 120 is located; if there is no spacing distance between them, the air delivered from the mixed flow outlet 222 cannot be fully mixed with the heat exchange air due to its too fast flow rate and is delivered inside, and the air supply effect of being cool but not cold cannot be achieved; but if the spacing distance between them is too large, the air delivered from the mixed flow outlet 222 cannot be blown to the main air supply outlet 120, and cannot be fully mixed with the heat exchange air.

In some preferred embodiments, the hook body 100 further includes an air guide plate 150, which is installed at the main air outlet 120, and the horizontal plane of the air guide plate 150 is perpendicular to the plane where the main air outlet 120 is located. That is, the flow direction of the air sent from the main air outlet 120 to the room is parallel to the horizontal plane of the air guide plate 150, so that the air heated by the heat exchanger 130 is sent out in a direction parallel to the air guide plate 150 as much as possible, and the air from the mixed flow outlet 222 can be completely blown to the air supply of the main air outlet 120, completely breaking up the heat exchange air sent from the main air outlet 120120, so that the heat exchange air and the indoor air are fully mixed to form a cross mixed flow air supply, so that the user feels a soft natural wind that is cool but not cold.

In particular, the indoor wall-mounted unit 10 of the air conditioner provided by the present invention has an air supply mixing flow component 200 added to the lower part of the wall-mounted unit body 100, and the air supply mixing flow component 200 includes a mixed flow cross-flow fan 210 and a mixed flow volute 220. The mixed flow volute 220 is provided with a mixed flow air inlet 221 and a mixed flow air outlet 222. The airflow of the mixed flow air inlet 221 comes from the main air supply port 120 and the indoor air at the same time. Especially in the cooling mode of the indoor unit, the gas cooled by the wall-mounted unit body 100 is fully mixed with the indoor hot gas, and the mixed gas forms a cool but not cold airflow, thereby forming comfortable cooling.

In some preferred embodiments, the diameter of the mixed crossflow fan 210 is smaller than the diameter of the main crossflow fan 140, so that the air volume of the mixed flow outlet 222 is smaller than the air volume of the main air supply port 120. If the diameter of the mixed crossflow fan 210 is greater than or equal to the diameter of the main crossflow fan 140, the heat exchange air volume delivered from the main air supply port 120 of the hook body 100 is smaller than or equal to the mixed flow air volume delivered to the room by the mixed flow outlet 222, so that the indoor temperature reaches the preset temperature very slowly, and the user experience is extremely poor.

Furthermore, on the mixed flow volute 220 , an air inlet grille 223 and an air outlet grille 224 are provided at the mixed flow air inlet 221 and the mixed flow air outlet 222 , respectively, which are used to ensure safety and prevent dust from entering the interior of the air supply mixed flow component 200 , thereby facilitating the cleaning of the air supply mixed flow component 200 .

Figure 4 is a schematic exploded view of the air supply mixed flow component 200 of the indoor hanging unit 10 shown in Figure 1. A motor 211 is provided at one end of the mixed flow crossflow fan 210, and a bearing 214 is provided at the other end. The rotating shaft of the motor 211 drives the mixed flow crossflow fan 210 to rotate with the bearing 214 as the axis. After the mixed flow crossflow fan 210 rotates, the heat exchange air delivered by the main air supply port 120 and the indoor air can be mixed; specifically, the rotating shaft of the motor 211 passes through the first motor bracket 212 to be connected to the mixed flow crossflow fan 210, and the motor 211 is fixed to one side of the mixed flow volute 220 through the second motor bracket 213; the bearing 214 and the bearing seat 215 are connected by interference fit to the mixed flow crossflow fan 210 and fixed to the other side of the mixed flow volute 220.

In addition, the mixed flow through-flow component provided by the present invention can operate independently of the hook body 100, and the user can choose whether to turn on the mixed flow through-flow component according to actual conditions to supply cool but not cold air to the air outlet of the main air supply port 120.

In other preferred embodiments, the air supply mixed flow component 200 is fixedly connected to the lower part of the hanging machine body 100 through the connecting member 300. Figure 5 is an enlarged schematic diagram of the connecting member 300 of the indoor hanging machine 10 shown in Figure 1. The connecting member 300 specifically connects the axial middle part of the air inlet grille 223 and the middle part of the lower end of the hanging machine body 100. The connecting member 300 connects the middle part of the air inlet grille 223, so that the air supply mixed flow component 200 and the hanging machine body 100 are point-to-point connected and matched. The structure is simple and beautiful, which simplifies industrial production and improves the production efficiency of air conditioners.

Specifically, the connecting member 300 includes a connecting shaft 310, and a connecting end 320 and a fixing end 330 are connected to the connecting shaft 310; wherein the connecting end 320 is an arc-shaped surface to match the arc of the air inlet grille 223, and is used to connect and fix the air supply mixed flow assembly 200; the fixing end 330 includes a fixing surface 331 fixed to the bottom of the housing of the hook body 100 and a connecting surface 332 along the fixing surface 331 toward the front of the indoor unit, and the connecting surface 332 is connected to the connecting shaft 310. Through the connection of the connecting member 300, the air supply mixed flow assembly 200 can be firmly fixed to the bottom of the hook body 100, so that the air supply mixed flow assembly 200 and the hook body 100 work in coordination. All the air from the mixed flow outlet 222 is blown toward the main air supply outlet 120, breaking up the heat exchange air in the main air supply outlet 120, making the heat exchange air and indoor air fully mixed, and the hot and cold air currents in different directions are dispersed and mixed with each other, and the air flow direction changes randomly, eventually forming a soft natural wind that is cool but not cold, thereby improving the user experience; or part of the air from the mixed flow outlet 222 is blown toward the main air supply outlet 120, while driving the jet port to form a hot air jet, eventually achieving a dual airflow mixing effect, greatly increasing the drainage volume, increasing the mixed flow temperature, and improving the cool but not cold experience effect, thereby achieving comfortable cooling.

The indoor hanging machine 10 of the present invention has an air supply mixed flow component 200 disposed at the lower part of the shell outside the hanging machine body 100, and is connected to the hanging machine body 100 through a connector 300. With such a structure, the user can install the air supply mixed flow component 200 separately without replacing the hanging machine body 100, and has strong operability. According to the needs of the user, it is flexible to choose whether to install the air supply mixed flow component 200. For example, for the room where young people live, they like strong air supply during cooling, so they can choose not to install the air supply mixed flow component 200 and use a traditional indoor air conditioner, or they can choose to install the air supply mixed flow component 200. The indoor hanging machine 10 with the air supply mixed flow component 200 can choose whether to turn it on according to the actual situation. For the room where the elderly and children live, it is necessary to install the air supply mixed flow component 200 for comfortable cooling.

At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention.
