Those skilled in the art should understand the specific meaning of the above terms in the present invention according to specific situations.
The embodiment of the invention provides an air conditioner. Air conditioners are used to condition indoor air, including conditioning the temperature, humidity, air quality of the air, humidifying, dehumidifying, introducing fresh air, and the like. The air conditioner can form a vapor compression refrigeration cycle system by an evaporator, a condenser, a compressor, a throttling device and other necessary elements so as to output cold air/hot air through a fan and realize refrigeration and heating of indoor environment.
The air conditioner of the embodiment of the invention can be a household air conditioner and also can be a central air conditioner. Specifically, the specific form of the air conditioner can be various forms such as a split wall-mounted type, a split vertical type, an integral type and a ceiling type. The embodiment of the present invention does not limit the specific form of the air conditioner at all. Fig. 1 to 5 illustrate only an embodiment of a floor type air conditioner.
Fig. 1 is a schematic front view of an air conditioner according to an embodiment of the present invention; FIG. 2 is a schematic right side view of the air conditioner shown in FIG. 1; fig. 3 is a schematic view of the lower half of the inside of the air conditioner shown in fig. 1.
As shown in fig. 1 to 3, an air conditioner according to an embodiment of the present invention may generally include a housing 10, a heat exchange air duct 11, a heat exchanger 40, a first fan 60, and a fresh air duct 30.
The casing 10 defines a structural body of the air conditioner, which defines a receiving space to receive main components of the air conditioner, such as a heat exchanger, a fan, a controller, and the like. Fig. 1 and 2 illustrate a casing of an indoor unit of a split-type floor air conditioner.
The heat exchange air duct 11 is disposed in the casing 10, and has an air supply outlet 112 for delivering heat exchange air flow to the indoor environment. Further, the heat exchange air duct 11 may further have an air inlet 111 to allow indoor air to enter the heat exchange air duct 11 through the air inlet 111. Both the supply air outlet 112 and the intake air inlet 111 penetrate the housing 10 to face the indoor environment. The air guide device 50 may be disposed at the air supply opening 112 for guiding the air outlet direction of the air supply opening 112.
A heat exchanger 40 is disposed within the housing 10 for exchanging heat with the airflow passing therethrough to form a heat exchange airflow. The heat exchanger 40 is an evaporator of a vapor compression refrigeration cycle system. The heat exchanger 40 may be disposed inside the heat exchange air duct 11, or may be disposed outside the heat exchange air duct 11.
The first fan 60 is disposed in the casing 10 for blowing the heat exchange air flow to the indoor environment through the blowing port 112, so as to condition the indoor air with the heat exchange air flow. The first fan 60 may be disposed inside the heat exchange air duct 11, or may be disposed outside the heat exchange air duct 11, or may be disposed at an inlet of the heat exchange air duct 11.
The fresh air duct 30 is disposed in the casing 10 and configured to introduce fresh air outdoors. The fresh air duct 30 has a bypass inlet 330 communicating with the heat exchange air duct 11 to allow a portion of the heat exchange air flow to enter the fresh air duct 30 through the bypass inlet 330 to be mixed with the fresh air flow. Because some heat exchange air flows are mixed, the temperature of the low-temperature fresh air flow is increased during heating, and the temperature of the high-temperature fresh air flow is reduced during refrigeration, so that the fresh air flow is blown to the indoor environment at a more comfortable temperature. Otherwise, if the outdoor cooler fresh air flow is directly blown to the indoor environment during heating in winter, the indoor heating effect is destroyed, and the human body feels uncomfortable. If when refrigerating in summer, outdoor hotter new trend air current directly blows to indoor environment, will destroy indoor refrigeration effect, and hot-blast blowing is also experienced the refrigeration that influences the human body to the human body.
Fig. 4 is a schematic physical structure diagram of the heat exchange air duct 11 in the air conditioner shown in fig. 3. The heat exchange duct 11 of fig. 3 is defined by a duct wall 116 (alternatively referred to as a volute) as shown in fig. 4.
In some embodiments, as shown in fig. 3 and 4, the first fan 60 may be a cross-flow fan, the heat exchange air duct 11 may be a cross-flow air duct, and one axial end of the heat exchange air duct 11 is provided with an air outlet 113 connected to the bypass inlet 330, so as to inject the heat exchange air flow into the fresh air duct 30. The open end of the heat exchange wind tunnel 11 may be provided with a support grid 1161, which functions to mount and support the first fan 60.
Because the cross-flow fan radially enters air and radially exits air, two axial ends of the conventional cross-flow air duct are closed and do not have a ventilation function. The axial end part of the through-flow air duct is opened in the embodiment, so that the effect of discharging partial heat exchange air flow to the fresh air duct 30 is achieved, and the conception is very novel and ingenious. And moreover, any obstruction to radial air inlet and air outlet of the cross-flow fan can not be caused.
Fig. 5 is a schematic physical structure diagram of the first fan 60 in the air conditioner shown in fig. 3.
Further, as shown in fig. 5, at least one blade 62 may be fixedly disposed at an axial end of the first fan 60 (cross-flow fan) for blowing out the heat exchange airflow in a direction axially away from the first fan 60 when the first fan 60 is operated, so that the heat exchange airflow flows into the fresh air duct 30. That is, as the first fan 60 rotates, the at least one blade 62 also rotates, applying a force to the airflow. In other words, the at least one blade 62 also forms a small fan, so that the heat exchange air flow in the cavity of the first fan 60 is applied to the fresh air duct 30. This design ingeniously utilizes the normal rotation of the first fan 60 to achieve bi-directional air supply (both radial and axial). Preferably, as shown in fig. 5, the number of the blades 62 is plural.
The first fan 60 includes a plurality of strip-shaped cross-flow blades 61 extending along the axial direction thereof, the plurality of cross-flow blades 61 are arranged at intervals along the circumferential direction of the first fan 60, and two ring-shaped mounting rings 63 are respectively arranged at two axial ends of the first fan 60. The plurality of blades 62 have one end connected to a radially inner side of the mounting ring 63 and the other end gathered at a center of the mounting ring 63 and connected to one mounting shaft 64. The mounting shaft 64 is used to mount the first fan 60 to the heat exchange air duct 11. It will be appreciated that a drive motor is connected to the upper end plate of the first fan 60.
As shown in fig. 5, the blades 62 are preferably axial flow blades, and the entire blades 62 constitute a single small axial flow impeller. The air inlet and the air outlet of the axial flow impeller are parallel to the axial direction of the axial flow impeller, so that the air flow can be sucked out from a cylindrical cavity formed by the through-flow blades 61 more conveniently.
In some embodiments, referring to fig. 2 and 3, for the embodiment of the floor air conditioner, the housing 10 may be defined with a lower chamber 12 below the heat exchange air duct 11, and the fresh air duct 30 is located in the lower chamber 12. That is, the position of the heat exchange air duct 11 is further upward, so that the position of the air supply opening 112 is further upward, so as to supply air to a further distance and enlarge the air supply distance and angle.
In some embodiments, as shown in fig. 1 and 3, the fresh air duct 30 has a fresh air inlet 310 and a fresh air outlet 320, the fresh air inlet 310 is used for connecting with the fresh air duct 80 connected to the outdoor environment, and the fresh air outlet 320 faces the indoor environment for exhausting fresh air.
Further, the fresh air inlet 310 may be located at the rear side of the housing 10 so as to be connected to the fresh air duct 80. The fresh air outlet 320 is located at the front side of the casing 10 so as to output fresh air forward. The present embodiment designs the fresh air duct 80 as an independent part detachably mounted to the housing 10, which can facilitate design, manufacture and transportation of the air conditioner.
In some embodiments, as shown in fig. 3, the air conditioner may further include a second fan 90. The second fan 90 is disposed in the lower chamber 12 for promoting the flow of the fresh air flow in the fresh air duct 30.
Further, as shown in fig. 3, the fresh air duct 30 may include an upstream section 31 and a downstream section 32. Wherein, the inlet of the upstream section 31 constitutes a fresh air inlet 310, and the outlet is connected to the inlet of the second fan 90. The inlet of the downstream section 32 is connected to the outlet of the second fan 90, the outlet constituting a fresh air outlet 320. In this embodiment, the second fan 90 includes not only a rotor, but also a housing for mounting the rotor and beginning with an inlet and an outlet. The aforementioned bypass inlet 330 is provided in the downstream section 32. The second fan 90 may be a centrifugal fan with its axis extending vertically, and the upstream section 31 is located below the second fan 90 and the downstream section 32 is located in front of the second fan 90. The new air duct 30 is divided into two sections in the embodiment, so that the height space and the depth space of the lower cavity 12 can be fully utilized, the second fan 90 is positioned outside the new air duct 30, the installation and the disassembly are convenient, and the structure is ingenious.
Further, as shown in fig. 3, the downstream section 32 may include a branch section 33, and an inlet of the branch section 33 constitutes the bypass inlet 330. Moreover, the air flow direction of the branch section 33 and the air flow direction of the main body part of the downstream section 32 form an acute angle, so that the fresh air flow can be prevented from being poured into the branch section 33, and the heat exchange air flow in the branch section 33 can also be prevented from being reversely poured into the fresh air flow.
In some alternative embodiments, the fresh air duct 30 may be an integral structure, the second fan 90 includes only a wind wheel, and the second fan 90 is disposed in the fresh air duct 30.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
