Description

TECHNICAL FIELD

[0001] The utility model relates to air conditioning equipment technical field, specifically provide a kind of air conditioner. BACKGROUND

[0002] The working principle of air conditioner is to realize refrigeration or heating by circulating air, the indoor air is inhaled through inlet, and the adjusted air is blown out by outlet after being processed by refrigeration or heating system inside air conditioner. If the inlet or outlet is blocked, the air circulation will be blocked, which leads to the air conditioner cannot work normally, and the working efficiency of air conditioner is reduced. The blocked inlet also affects the amount of inhaled air, reduces the air volume, and affects the refrigeration or heating effect. When the inlet or outlet is blocked, the air conditioner needs to consume more energy to overcome the resistance of air circulation, which will lead to energy efficiency reduction and increase electricity bill. At the same time, due to poor air circulation, the refrigeration or heating system inside air conditioner may be overheated or cooled, which affects the performance and service life of the equipment. If the air conditioner runs under the condition of poor air circulation for a long time, the motor and compressor inside air conditioner may be overheated, which may cause failure or even fire hazard.

[0003] The inlets and outlets of most air conditioners are usually located on different sides of the shell, for example, rear inlet and front outlet or upper inlet and front outlet, which requires the air conditioner to be placed considering the smoothness of inlet and outlet. It cannot be blocked at will. In the layout of the house, a specific space is usually reserved for the air conditioner, which limits the flexibility and aesthetics of the house to some extent. If it is placed in the cabinet, the side wall, top plate, etc. of the cabinet may block the inlet and / or outlet. In order to ensure sufficient air circulation to ensure the normal operation of the air conditioner, holes or gaps corresponding to the inlet and / or outlet need to be opened on the cabinet to ensure that air can flow in and out of the air conditioner smoothly. The position, size and shape of the hole or gap need to be carefully designed to ensure that air can circulate along the predetermined path. If the air conditioner is placed against the wall, the outlet or inlet is easy to be blocked by the surrounding curtain. Therefore, the structure of the existing air conditioner is not conducive to the integration of the house.

[0004] Even if the inlet and outlet can be set on the same side to solve the problem that the air conditioner is not conducive to the integration of the house, but this improved air conditioner is often limited by the space of home decoration, which leads to insufficient air intake and cannot achieve faster temperature adjustment in the room.

[0005] Correspondingly, there is a need in the art for a new technical solution to solve the above problems. UTILITY MODEL CONTENT

[0006] The utility model aims at solving above-mentioned technical problem, namely solves the problem that the indoor temperature adjustment efficiency is relatively slow due to being limited by the space of home decoration in the process of home integration of existing air conditioner.

[0024] Furthermore, in order to more clearly show the core technical scheme of the utility model, the description below omits the description of the known structure of the air conditioner, but this omission is only for the convenience of description and does not mean that the air conditioner can be without these structures.

[0025] Figure 1 It is the structure schematic diagram of the air conditioner in the utility model, and the left view of the internal structure of the air conditioner is shown after being placed on the ground. Figure 2 It is the front view of the air conditioner in the utility model. As shown in Figures 1 to 2 The utility model discloses an air conditioner, which comprises a shell 1, an air inlet 2 and an air outlet 3, the air inlet 2 and the air outlet 3 are arranged on the same side surface of the shell 1, a cavity is arranged in the shell 1, the air inlet 2, the cavity and the air outlet 3 are sequentially communicated, an evaporator 4 is arranged in the cavity, a first fan 5 is rotatably arranged in the cavity, the air inlet end of the first fan 5 faces the air inlet 2, and the first fan 5 is used for sucking external air into the cavity from the air inlet 2, a second fan 6 is rotatably arranged in the cavity, the air inlet end of the second fan 6 faces the air outlet end of the first fan 5, the air outlet end of the second fan 6 is communicated with the evaporator 4, and a driving member 7 is arranged in the cavity and used for driving the first fan 5 and the second fan 6 to rotate.

[0026] In the embodiment, in order to solve the problem of small air inlet of the air conditioner under the concept of home integration, the air conditioner provided by the utility model comprises a shell 1, an evaporator 4, a first fan 5, a second fan 6 and a driving member 7. A cavity is arranged in the shell 1, the air inlet 2, the cavity and the air outlet 3 are sequentially communicated, and the air inlet 2 and the air outlet 3 are arranged on the same side surface of the shell 1. When the air conditioner is designed for home integration, the air inlet 2 and the air outlet 3 are located on the side surface of the air conditioner facing the indoor. The evaporator 4, the first fan 5, the second fan 6 and the driving member 7 are located in the cavity, wherein the air inlet end of the first fan 5 faces the air inlet 2, the air outlet end of the first fan 5 faces the air inlet end of the second fan 6, the air outlet end of the second fan 6 is communicated with the evaporator 4, and the driving member 7 is used for driving the first fan 5 and the second fan 6 to rotate simultaneously.

[0027] When the first fan 5 and the second fan 6 are rotating, the first fan 5 sucks air from outside the air conditioner through the air inlet 2, and then the air flows through the second fan 6, the evaporator 4 and then flows out from the air outlet 3. Because two fans are provided, the second fan 6 assists to increase the air volume sucked in through the air inlet 2, so that the air volume is effectively increased in a limited space. Compared with the mode that the first fan 5 and the second fan 6 are respectively driven by two driving devices, the mode that the first fan 5 and the second fan 6 are simultaneously driven by one driving member 7 in the embodiment can reduce the energy consumption for driving the fans.

[0028] In addition, the air inlet 2 and the air outlet 3 are both arranged on the same side of the shell 1, for example, the front side of the shell 1 faces the indoor space, then the air inlet 2 and the air outlet 3 are both arranged on the front side of the shell 1, front side air inlet and front side air outlet, so that when the air conditioner is integrated with the furniture, only the arrangement position of the side is needed to be considered, which greatly improves the flexibility and convenience of placing the air conditioner, and solves the problem that the existing air conditioner is not conducive to the integration with the furniture. If it is placed in a cabinet, only the side is needed to be considered not to be blocked, and no hole needs to be opened on different sides of the cabinet, which reduces the construction amount of adapting the furniture when the air conditioner is placed with the furniture, avoids damaging the overall aesthetics of the furniture, and is easy to clean and maintain the air conditioner in the later period. If it is placed against a wall, only the side of the air inlet and outlet is needed to be avoided by the curtain.

[0029] Further, as shown in Figure 1 and Figure 2 , the driving member 7 is located between the first fan 5 and the second fan 6.

[0030] In the embodiment, in order to make full use of the space, the driving member 7 is arranged between the first fan 5 and the second fan 6, which is also convenient for the driving member 7 to simultaneously drive the first fan 5 and the second fan 6. In addition, the arrangement of the driving member 7 between the first fan 5 and the second fan 6 can provide the first fan 5 and the second fan 6 with similar power, thereby avoiding the mutual influence of the first fan 5 and the second fan 6 in power.

[0031] It needs to be specially pointed out that the driving member 7 can include a driving motor and a speed reducer, the driving motor is electrically connected with the controller built in the air conditioner, the speed reducer is arranged in the cavity, the speed reducer can have one input shaft and two output shafts, the input shaft of the speed reducer can be connected with the driving motor through a shaft coupling, and the two output shafts of the speed reducer can be connected with the first fan 5 and the second fan 6 through shaft couplings respectively.

[0032] Further, as shown in Figure 1 and Figure 2 , the first fan 5 is an axial fan, and / or the second fan 6 is a centrifugal fan.

[0033] In this embodiment, in order to minimize the space occupied by the air path in the horizontal direction, the first fan 5 is an axial fan, and the second fan 6 is a centrifugal fan. The air sucked by the axial fan and the air blown by the axial fan are both along the axis of the rotating shaft of the axial fan, and the air sucked by the centrifugal fan and the air blown by the centrifugal fan are generally perpendicular. According to the characteristics of the two fans, the first fan 5 is selected as an axial fan, and the second fan 6 is selected as a centrifugal fan. The external air flows through the axis of the axial fan to the centrifugal fan, and then the flow direction of the fan is changed by the centrifugal fan. In this way, the outflow direction of the centrifugal fan and the position of the evaporator 4 can be flexibly adjusted. In addition, the air suction capacity of the axial fan is generally larger than that of the centrifugal fan. Therefore, the axial fan is arranged at the air inlet, which can make the air suction capacity of the air conditioner better.

[0034] Further, as shown in Figure 1 and Figure 2 , the first fan 5 and the second fan 6 are coaxially arranged so that the driving member 7 drives the first fan 5 and the second fan 6 at the same time. By coaxially driving the first fan 5 and the second fan 6 to rotate through the driving member 7, the air inlet capacity can be increased, the overall size of the improved air conditioner can be reduced, and the energy consumption can be reduced. For example, the power of a single fan is 60w, the rotating speed is 750r / min, and the hourly power consumption is 0.06kw / h. If two motors are used to drive two fans, the hourly power consumption is 0.12kw / h. In this embodiment, the first fan 5 and the second fan 6 are coaxially driven to rotate by the driving member 7. When the voltage U and the current I of the driving member 7 are unchanged, the power is still 0.06kw / h, which is less than the power consumption 0.12kw / h when two motors work independently. Although the rotating speed will decrease, experimental data shows that the overall air inlet capacity increases. It should be specially noted that the selection of the first fan 5 and the second fan 6 should take into account the power of the driving member to avoid the driving member from being unable to drive due to improper selection.

[0035] Further, as shown in Figure 1 and Figure 2 , the evaporator 4 is located between the second fan 6 and the air outlet 3.

[0036] In this embodiment, in order to make the flowing gas have a better heat displacement effect, the evaporator 4 is arranged between the second fan 6 and the air outlet 3. The first fan 5 is close to the air inlet 2, the evaporator 4 is close to the air outlet 3, and the second fan 6 is between the first fan 5 and the evaporator 4. In this way, the smoothness of the gas during the flow process can be ensured, and the influence of the gas after completing heat displacement on the fan can be avoided. This influence not only reduces the temperature adjustment efficiency of the air conditioner, but also causes the service life of the fan to decrease sharply.

[0037] Further, as shown in Figure 1 and Figure 2As shown, the air inlet 2 is located below the air outlet 3.

[0038] In this embodiment, since the hot air is generally above the cold air, in order to quickly complete the replacement of the indoor air heat, the air inlet 2 is arranged below the air outlet 3.

[0039] Further, as shown in Figure 1 and Figure 2 , the air conditioner further comprises an air inlet grille 8, which is arranged at the air inlet 2.

[0040] In this embodiment, in order to prevent external impurities from entering the air conditioner, the air inlet grille 8 is further arranged on the shell 1. The air inlet grille 8 can prevent larger impurities from entering the air conditioner, thereby protecting the components in the air conditioner and improving the overall service life. It also avoids the need for frequent maintenance by the user during normal use.

[0041] Further, as shown in Figure 1 and Figure 2 , the air inlet grille 8 is at an angle with the horizontal plane. By changing the angle between the air inlet grille 8 and the horizontal plane, the air inlet direction when the air inlet 2 inhales air can be adjusted; when the air inlet grille 8 is inclined upward, the air inlet 2 inhales external air from above; when the air inlet grille 8 is inclined to the ground, the air inlet 2 inhales external air from above.

[0042] In addition, in this embodiment, in addition to facilitating home integration, the return air problem also needs to be considered, that is, if the air inlet and outlet are located on the same side, the air blown out of the air outlet 3 may be sucked into the air inlet 2 in a short time. In order to solve this problem, in this embodiment, the air inlet grille 8 is preferably inclined to the ground, so that the air inlet 2 inhales external air from below. After the air outlet 3 blows the air out of the shell 1 from the front, the air inlet 2 inhales the indoor air into the shell 1 from below the front of the air inlet 2 through the air inlet grille 8, avoiding the blown gas directly entering the air conditioner, and reducing the return air problem caused by the air inlet and outlet being arranged on the same side.

[0043] Further, as shown in Figure 1 and Figure 2 Figure 1 Figure 2 , the air conditioner further comprises an air filter screen, which is arranged at the air inlet 2 and the air outlet 3, respectively.

[0044] In the embodiment, in order to avoid too much dust into the air conditioner, and then is not conducive to the user himself to clean the dust in the air conditioner, and ultimately will affect the customer experience. In the air inlet and air outlet are provided with air filter screen, air filter screen is usually used to filter the impurities or dust invisible to the naked eye in the air, air filter screen is set in the way of clamping, and the air filter screen is a common product on the market, so as to facilitate the customer to replace. The clamping structure is also a common structure, so as to be simple to operate, and the user does not need to use any tool in the replacement process.

[0045] Further, the air conditioner further comprises an air outlet grille (not shown in the figure), and the air outlet grille is arranged on the air outlet 3. The air outlet grille can control the air outlet direction, and the user can adjust the included angle between the air outlet grille and the ground to control the air outlet direction according to the need, so as to avoid the air conditioner wind directly blowing on the body.
