Detailed Description
In the following description of the wall-mounted air conditioning indoor unit according to the embodiment of the present invention, referring to fig. 1 to 10, the directions or positional relationships indicated by "front", "rear", "upper", "lower", "left", "right", "inner", "outer", and the like are based on the directions or positional relationships shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific direction, be configured and operated in a specific direction, and thus, should not be construed as limiting the present invention.
As shown in fig. 1 to 4 and 6, the wall-mounted air conditioning indoor unit according to the embodiment of the present invention includes a casing 10, an evaporator 70, two cross-flow fans, i.e., a first cross-flow fan 21 and a second cross-flow fan 22, two air ducts, i.e., a first air duct and a second air duct (only a second air duct 90 on the right side is illustrated in fig. 6), and an air cleaning device. The wall-mounted air conditioner indoor unit and the air conditioner outdoor unit together form a vapor compression refrigeration cycle system for refrigerating/heating the indoor environment.
The housing 10 may specifically include a skeleton 11, a shell 12, a left end cap 14, and a right end cap 15. The framework 11 constitutes the main supporting structure of the indoor unit. The shell 12 covers the framework 11. Two air outlets 101 arranged side by side along the left-right direction are arranged at the bottom of the housing 12, and an air inlet 121 is arranged at the top of the housing 12. Indoor air enters the inside of the casing 10 through the air inlet 121 under the action of the two cross-flow fans, and forms heat exchange air after finishing heat exchange with the evaporator 70, and the heat exchange air is blown to the indoor from the two air outlets 101 to perform cooling/heating.
The first air duct and the second air duct are arranged in the casing 10 side by side in the left-right direction, and are respectively used for guiding heat exchange air after exchanging heat with the evaporator 70 to the two air outlets 101.
The first cross flow fan 21 and the second cross flow fan 22 are cylindrical structures, and the axes of the first cross flow fan and the second cross flow fan are arranged in the two air ducts 90 side by side in a manner of extending along the left-right direction so as to respectively match with the two air outlets 101.
The air cleaning device is provided inside the case 70 for cleaning indoor air. Specifically, the air cleaning device includes a sterilization module 72, a negative ion generation module 76, and an electrostatic precipitation module 74. Wherein the sterilization module 72 is mounted on the evaporator 70 and configured to release negative ions and ozone after being powered on to remove bacteria and mold in the housing 10 and to inhibit growth of bacteria and mold in the housing 10.
The anion generating module 76 is installed at the air outlet 101, and is configured to release anions that will enter the indoor space with the wind, and can sterilize the air blown out from the air outlet 101, and can also make dust in the air charged with static electricity. An electrostatic precipitator module 74 is also mounted to the evaporator 70 and is configured to adsorb electrostatically charged dust in the air to effect dust removal. The three modules of the air cleaning device are all connected with a main control board of the indoor unit and controlled by the main control board.
It is preferable that the sterilizing module 72 is provided on a side surface of the evaporator 70 facing away from the first and second cross flow fans 21 and 22. For example, as shown in fig. 2, the evaporator 70 may be a three-stage evaporator, which encloses two cross-flow fans inside thereof), and the sterilizing module 72 may be disposed on the outer surface of the evaporator 70, so that when two cross-flow fans draw air through the evaporator 70, the negative ions emitted from the sterilizing module 72 and ozone can pass through the evaporator 70 under the suction force, so that the evaporator 70 is sufficiently cleaned. For the same reason, it is preferable that the electrostatic precipitator module 74 is also provided on the surface of the evaporator 70 facing away from the first and second cross flow fans 21 and 22, as shown in fig. 2.
In some embodiments, the degerming module 72 may be disposed at an end of the evaporator 70 near a main control panel of the wall-mounted air conditioner indoor unit so as to be electrically connected to the main control panel and be powered and controlled by the main control panel. For example, as shown in fig. 2, a main control panel (not shown) is located on the right side of the housing 10, with the mold device 72 also being located on the right side of the evaporator 70 so that its wires are connected to the main control panel.
In some embodiments, the first air duct and the second air duct are disposed in a staggered manner in the front-rear direction, so that the air supply distances of the two air outlets are different. For example, the first air duct is positioned more forward than the second air duct, so that the air supply distance of the first air outlet is longer.
In some embodiments, the axes of the first cross flow fan 21 and the second cross flow fan 22 are not arranged coaxially, so that the distance between the two and the corresponding air outlet is different. For example, the distance between the first cross flow fan 21 and the left air outlet 101 may be smaller than the distance between the second cross flow fan 22 and the right air outlet 101.
The wall-mounted air conditioner indoor unit can realize multiple air supply modes. According to the air supply requirement, when the air supply quantity requirement is small, the air conditioner can only start the first cross flow fan 21 or only start the second cross flow fan 22, so that the energy consumption of the fans is reduced. When the air supply quantity demand is large, two cross flow fans can be simultaneously started to realize quick refrigeration/heating and large-air-quantity refrigeration/heating.
The embodiment of the invention realizes the air supply differentiation of the two air outlets. If the distance between the human body and the indoor unit is far, the first through-flow fan 21 with a far air supply distance can be started, and only the air outlet on the left side supplies air; and two cross-flow fans can be selected to be started simultaneously, so that the two air outlets supply air. When the distance between the human body and the indoor unit is shorter, the second cross-flow fan 22 with shorter air supply distance can be turned on, so that the air outlet on the right side supplies air.
In some embodiments, the diameter of the first cross flow fan 21 may be equal to that of the second cross flow fan 22, and the length of the first cross flow fan 21 is longer than that of the second cross flow fan 22, so that the air volume of the first cross flow fan 21 is larger than that of the second cross flow fan 22 at the same rotation speed. Thus, the first through-flow fan 21 having a long air flow distance has a large air flow rate, and can contribute to long-distance air supply. The air quantity of the second cross flow fan 22 with a short air supply distance is small, short-distance air supply is facilitated, and the phenomenon that a human body with a short distance from an indoor unit feels strong air and is uncomfortable is avoided.
The first air duct and the second air duct are both limited by a volute tongue and a volute positioned behind and below the volute tongue. As shown in fig. 6, the second air duct 90 is defined by a volute tongue 91 and a volute 92 located behind and below the volute tongue 91. The volute tongue of the first air duct and the volute tongue of the second air duct are arranged in a staggered mode in the front-back direction, and the volute of the first air duct and the volute of the second air duct are arranged in a staggered mode in the front-back direction, so that the first air duct and the second air duct are arranged in a staggered mode in the front-back direction.
In some embodiments, the front edge of the volute (such as the volute 92 of the second air duct shown in fig. 6) is connected with the anti-condensation plate 80 extending obliquely downward and rearward, the lower edge of the anti-condensation plate 80 is connected to the housing 90, and the surface of the anti-condensation plate is formed with a plurality of ribs 801.
In this embodiment, when the air conditioner is used for cooling and cold air is blown out from the air outlet 101, the temperature of the casing part of the air outlet 101 is low, and water vapor in the air is likely to be condensed into condensed water on the casing surface. In order to avoid the dripping of the condensed water, the convex rib 801 arranged on the condensation-preventing plate 80 can increase the contact area with the cold air, and the condensed water formed on the condensation-preventing plate can not be condensed into larger water drops to drip due to the obstruction of the convex rib 801. It is preferable that the plurality of ribs 801 extend in the left-right direction and are parallel to each other, so that the condensed water can be better blocked, and the condensed water is prevented from flowing down along the groove formed between two adjacent ribs 801.
In some embodiments, as shown in fig. 1-4, the upper edge of the condensation preventing panel 80 is bent forward and downward to form a rib 82. When the heat exchange air is blown out at a high speed from the air outlet 101, negative pressure is formed, the indoor air can flow to the heat exchange air along the condensation preventing plate 80 under the action of the negative pressure at the air outlet to form drainage air, and the drainage air and the heat exchange air are mixed to form mixed air. So, when refrigerating, the temperature of mixed wind is higher than heat exchange wind, and when heating, the temperature of mixed wind is less than heat exchange wind, and the homoenergetic makes the air-out more comfortable. After the guide wind meets the flange 82, the guide wind is baffled forwards and downwards to flow in parallel with the heat exchange wind, so that the noise caused by the direct impact of the guide wind on the heat exchange wind is avoided. In addition, the arrangement of the blocking edge 82 can also enable the mixing area of the heat exchange air and the drainage air to be far away from the indoor unit, and can reduce condensation on the surfaces of various parts of the indoor unit.
In some embodiments, as shown in fig. 5 to 7, the wall-mounted air conditioning indoor unit further includes a bearing member 60. The motor 211 for driving the first cross flow fan 21 is provided on the left side thereof, and the motor 222 for driving the second cross flow fan 22 is provided on the right side thereof. The frame 11 may be provided with a motor cover 141 and a motor cover 151 for respectively mounting the motor 211 and the motor 222.
The bearing member 60 is attached to the housing 10, and specifically, the bearing housing 16 may be attached to the frame 11, and the bearing member 60 may be attached to the bearing housing 16. The left end of the bearing member 60 is connected to the right rotary shaft of the first cross flow fan 21, and the right end of the bearing member 60 is connected to the left rotary shaft of the second cross flow fan 22.
Specifically, the bearing member 60 may include a bearing having a relatively large axial dimension, which may be a radial bearing commonly used in the art, such as a deep groove ball bearing. Alternatively, more preferably, as shown in fig. 7, the bearing member 60 may also include a cylindrical housing 61 and two bearings 62. The cylindrical casing 61 has two cylindrical cavities 611 at both axial ends (the two cylindrical cavities 611 may be arranged non-coaxially so that the two cross-flow fans are not coaxial). Two bearings 62 are mounted in the two cylindrical cavities 611, respectively. The two bearings 62 are used to connect the right end rotation shaft of the first cross flow fan 21 and the left end rotation shaft of the second cross flow fan 22, respectively. The cylindrical housing 61 is detachably mounted in the bearing housing 16.
In other structures, two bearings which are completely independent from each other can be directly adopted to be matched with the rotating shafts of the two cross-flow fans, but in order to achieve smooth installation, enough operating space needs to be reserved between the two bearings, and the existence of the space is equivalent to the shortening of the effective length of the two cross-flow fans. Or, the air volume of the section of the evaporator corresponding to the operating space is almost zero, which will affect the heat exchange effect of the evaporator. Moreover, the portion of the front side of the housing corresponding to the operating space cannot be provided with an air outlet, which indirectly affects the length of the air outlet 101.
In the present embodiment, an integrated bearing member 60 is used to connect two cross-flow fans, and the integrated bearing member 60 does not need to reserve the above-mentioned operating space for two bearings installed independently. Even if the bearing member 60 includes two bearings 62, the distance between the two bearings 62 may be set to zero. Therefore, the occupied space of the integrated bearing component 60 is smaller, the influence on the heat exchange performance of the evaporator 70 is smaller, the influence on the length of the air outlet 101 is smaller, and the performance of the whole machine is better. Furthermore, the use of the integrated bearing component 60 will of course also simplify the assembly process.
In some embodiments, as shown in fig. 1, 5, 8, and 9, the wall-mounted air conditioning indoor unit further includes two air guiding devices 50. Each air guiding device 50 is disposed at one air outlet 101, and is used for adjusting the air outlet directions of the two air outlets 101. Each air guide device 50 comprises an air guide plate 52 and a swinging blade assembly. The air deflector 52 is disposed inside one of the outlets 101, and is configured to adjust the vertical direction of the outlet 101 to rotate around an axis extending in the horizontal direction. The rotating shaft 521 at one end of the air deflector 52 close to the middle of the casing 10 is inserted into the shaft hole 112 of the side plate 111, and the rotating shaft 521 at the other end is connected with a motor 523, and the motor 523 is used for driving the air deflector 52 to rotate. The swing blade assembly is disposed inside one air outlet 101, and includes a plurality of swing blades 51, and the plurality of swing blades 51 can swing left and right to adjust the left and right wind directions of the air outlet 101. Specifically, as shown in fig. 9, each swing blade assembly further includes a link 53 and a stepping motor. The length direction of the connecting rod 53 extends along the left-right direction and can reciprocate along the length direction, and different parts of the length direction of the connecting rod 53 are respectively hinged with one swing blade 51, so that the connecting rod 53 drives the swing blades 51 to synchronously swing left and right when reciprocating along the length direction. The step motor is configured to drive the connecting rod 53 to reciprocate along the length direction thereof, and it is generally known in the mechanical field how to convert the rotation of the step motor into the translation motion of the connecting rod 53, and the details are not repeated herein.
Two air ducting 50 and two air outlets 101 can send wind to two directions, perhaps make the directional air supply of an air outlet 101, and the wind is swept in another supply-air outlet circulation, perhaps makes the air-out of two air outlets 101 mix mutually, forms mixed flow wind, promotes user's comfort level.
In some embodiments, as shown in fig. 1, the wall-mounted air conditioning indoor unit further includes an environment information detecting device 40 configured to controllably detect indoor environment information including a human body surface temperature, human body position information, and a distance between a human body and the wall-mounted air conditioning indoor unit in a room, so as to adjust wind speeds of the first cross flow fan 21 and the second cross flow fan 22 to wind directions of the two wind outlets 101 according to the indoor environment information. For example: the air outlet direction is adjusted according to the position of the human body, so that cold air can keep away from people, and hot air can face. The wind speed (namely the wind quantity) of the cross flow fan is adjusted according to the surface temperature of the human body. The wind speed (wind volume) is adjusted according to the distance between the human body and the wall-mounted air conditioner indoor unit.
The environmental information detecting device 40 may include a human body temperature detecting module and an infrared detection sensing module. The infrared detection sensing module can sense the number of indoor users, can acquire the position of each human body and can sense the distance between the human body and the infrared detection sensing module, and the distance between the human body and the infrared detection sensing module can be regarded as the distance between the human body and the indoor unit of the wall-mounted air conditioner because the environment information detection device 40 is positioned on the indoor unit of the wall-mounted air conditioner. The use of infrared or other sensors to detect the number, location, etc. of the human body is well known to those skilled in the art, and the specific principles thereof will not be described in detail herein. The human body temperature detection module can detect the human body surface temperature of an indoor user. The use of infrared radiation to sense body temperature is also well known in the art and the specific principles thereof will not be described in detail herein.
