The present invention belongs to the technical field of air conditioning, and more particularly relates to improvement of construction of an air duct assembly, and an integrated air conditioner with the air duct assembly.
The integrated air conditioner is relative to the air-conditioning split machine, an indoor heat exchanger, an outdoor heat exchanger, a compressor, a throttling component, a four-way valve, pipes and all other system components that make up the system are all in an integral housing; an air duct is formed in the housing; an indoor air inlet, an indoor air outlet and an indoor draught fan are arranged at an indoor side, and an outdoor air inlet, the indoor air inlet and an outdoor draught fan are arranged at an outdoor side. A common window air conditioner is a type of integrated air conditioner.
Because of the characteristics of simple structure, convenient installation and space saving (no need to find space to install the outdoor machines), easy moving and low operating noise, and major convenience to life, the integrated air conditioners have been recognized by more and more occasions and people, especially for areas and families with a very small living area per capita.
As we all know, in order to achieve a good cooling and heating effect, and save energy and reduce consumption, when the air conditioner is turned on, the indoor doors and windows are usually closed, however, as users breathe, the indoor oxygen content is getting lower and lower and the carbon dioxide content is getting higher and higher over time, resulting in that the air is not fresh, or even causing suffocating. If the doors and windows are opened at this time, it will cause energy loss and affect the indoor temperature, and when the outdoor air quality is poor, such as smoggy weather, opening the doors and windows will make indoor air quality worse and worse.
In order to solve the above technical problems, an air ventilation recycle system has appeared on the market. The air ventilation recycle system is an effective air purification device that can circulate the indoor air. On one hand, foul indoor air is discharged to the outside, and on the other hand, fresh outdoor air is subjected to sterilization, disinfection, filtration and other measures, and then input into the room to improve the indoor air quality, which can ensure that the air entering the room is clean and healthy, so the air ventilation recycle system is more and more popular among users. However, on the one hand, the use of the air ventilation recycle system to input fresh air into the room will occupy indoor space, and on the other hand, the air ventilation recycle system needs to be purchased separately, which increases the user's use cost. In the prior art, the integrated air conditioner, taking the window air conditioner as an example, does not have an air-conditioning product that can realize both the air conditioning function and the function of the air ventilation recycle system. The existing solution is only to open a small hole (if the diameter is too large, the cooling and heating effect will be influenced and the energy consumption will be increased) on the indoor side of the window air conditioner, so that a small amount of fresh air can enter the room, and the ventilation effect is poor, which cannot be compared with the ventilation effect of a dedicated air ventilation recycle system.
The present invention proposes an air duct assembly and an integrated air conditioner for the technical problem that the integrated air conditioner cannot achieve both the air conditioning function and the fresh air exchange function in the prior art.
In order to realize the aim of the present invention, the present invention adopts the following technical scheme:
an air duct assembly, which includes:
a fixed shell, provided with an indoor air inlet duct and an indoor air outlet duct positioned at an indoor side, as well as an outdoor air inlet duct and an outdoor air outlet duct positioned at an outdoor side; the fixed shell is internally provided with an air duct cavity located between the indoor side and the outdoor side, and the indoor air inlet duct, the indoor air outlet duct, the outdoor air inlet duct and the outdoor air outlet duct are all communicated with the air duct cavity;
a rotating air duct body, rotatably disposed in the air duct cavity, a first air duct and a second air duct apart from each other are formed in the rotating air duct body, and the rotating air duct body has a first position and a second position; and
when the rotating air duct body is at the first position, the indoor air inlet duct is communicated with the indoor air outlet duct, the outdoor air inlet duct is communicated with the outdoor air outlet duct, the indoor air inlet duct is disconnected from the outdoor air outlet duct and the outdoor air inlet duct, the indoor air outlet duct is disconnected from the outdoor air outlet duct and the outdoor air inlet duct; and when the rotating air duct body is at the second position, the indoor air inlet duct is communicated with the first air duct and the outdoor air outlet duct to form a turbid air exhaust duct, the indoor air outlet duct is communicated with the second air duct and the outdoor air inlet duct to form a fresh air inlet duct, and the turbid air exhaust duct is apart from the fresh air inlet duct.
Further, the rotating air duct body is cylindrical, and includes two coaxially arranged circular end plates, two vertical partitions located between the two circular end plates with two ends correspondingly and fixedly connected to the two circular end plates, and a lateral partition located between the two vertical partitions, two sides of the lateral partition are respectively and fixedly connected to the two vertical partitions to divide an internal space enclosed by the two vertical partitions and the two circular end plates into the first air duct and the second air duct, and both ends of the lateral partition are free ends.
Furthermore, both of the vertical partitions have recesses recessed toward the inside of the rotating air duct body, and the recesses are configured to respectively communicate the indoor air inlet duct and the indoor air outlet duct, and communicate the outdoor air inlet duct and the outdoor air outlet duct when the rotating air duct body is at the first position.
In order to rotate the rotating air duct body smoothly, the air duct cavity is a cylindrical cavity matched with the rotating air duct body, and one end of the air duct cavity penetrates through the fixed shell along an axial direction.
Further, when the rotating air duct body is at the first position, a vertical edge of the vertical partition matches and fits an inner wall of the air duct cavity, edges at two ends of the lateral partition match and fit the inner wall of the air duct cavity; and when the rotating air duct body is at the second position, the vertical edge of the vertical partition matches and fits the inner wall of the air duct cavity, and the edges at the two ends of the lateral partition match and fit the inner wall of the air duct cavity.
In order to reduce the length of an internal airflow path and reduce the airflow resistance, the indoor air outlet duct is arranged opposite to the outdoor air inlet duct, and the indoor air inlet duct is arranged opposite to the outdoor air outlet duct.
The air duct assembly further includes a rotating driving component for driving the rotating air duct body to rotate.
Further, the rotating driving component is a motor, and is fixedly mounted on an outer wall of the shell, one of the circular end plates of the rotating air duct body is correspondingly provided with a central rotating shaft, and the central rotating shaft is connected to an output shaft of the motor.
A limiting structure is disposed on the fixed shell, and is configured to prevent the rotating air duct body from being separated from the fixed shell, so as to make the overall operation reliable.
The present invention also provides an integrated air conditioner, which includes an air duct assembly, and the air duct assembly is the above-mentioned air duct assembly.
Compared with the prior art, the advantages and positive effects of the present invention are:
In the present invention, the rotatable rotating air duct body is arranged in the fixed shell of the air duct assembly. When the rotating air duct body is at the first position, the indoor air inlet duct is communicated with the indoor air outlet duct, and the outdoor air inlet duct is communicated with the outdoor air outlet duct; the indoor air inlet duct is disconnected from the outdoor air outlet duct, and the indoor air inlet duct is disconnected from the outdoor air inlet duct, so that the internal air duct of the air duct assembly is divided into a part close to the indoor side and a part close to the outdoor side, and the two parts do not affect each other, thereby satisfying the realization of the air conditioning function on the integrated air conditioner. When the rotating air duct body is at the second position, the indoor air inlet duct is communicated with the first air duct and the outdoor air outlet duct to form a turbid air exhaust duct; and the indoor air outlet duct is communicated with the second air duct and the outdoor air inlet duct to form a fresh air inlet air duct. The turbid air exhaust duct and the fresh air inlet duct are separated from each other, the two parts of the air ducts do not affect each other, and satisfies the fresh air exchange function on the integrated air conditioner. Thus the present invention makes the internal air duct of the air duct assembly variable through the rotatable rotating air duct body, thereby realizing the switch of the air conditioning function and the fresh air exchange function when being used for the integrated air conditioner, and the air duct with a larger space participates in the exchange of the fresh air when the fresh air exchange function is realized; compared with the existing scheme that only a small hole is arranged on the indoor side of the window air conditioner so that a small amount of fresh air can enter the room, the effect of fresh air exchange is greatly improved.
