Description

Air duct device and air conditioner integrated machine

Technical field

The invention belongs to the technical field of air conditioning, and specifically relates to the structural improvement of an air duct device and an air conditioner integrated machine with the air duct device.

Background technique

The air conditioner integrated machine is relative to the air conditioner split machine, the indoor heat exchanger, outdoor heat exchanger, compressor, throttling parts, four-way valve, pipeline and all other system components that make up the system are all in an integral shell Inside, an air duct is formed in the shell, and indoor air inlets, indoor air outlets, and indoor fans are set on the indoor side of the shell, and outdoor air inlets, indoor air inlets and outdoor fans are set on the outdoor side of the shell, common window air conditioners It is a kind of air conditioner.

All-in-one air conditioners have been recognized by more and more occasions and people because of their simple shape, convenient installation and space saving (no need to find space to install the external unit), easy to move and low operating noise, and bring major convenience to life. It is for areas and families with very small living area per capita.

technical problem

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. As the user breathes, the indoor oxygen content becomes lower and lower and the carbon dioxide content increases over time. The higher it is, the air is not fresh and even becomes stuffy. If you open the doors and windows at this time, it will cause energy loss and affect the indoor temperature, and when the outdoor air quality is poor, such as haze weather, opening the doors and windows will cause the indoor air quality to become worse and worse.

In order to solve the above technical problems, a new fan has appeared on the market. The new fan is an effective air purification device that can circulate the indoor air. On the one hand, it discharges the dirty indoor air outside, and on the other hand, it discharges the fresh outdoor air. After sterilization, disinfection, filtration and other measures, it is imported into the room to improve the indoor air quality and ensure that the air entering the room is clean and healthy. It is more and more popular with users. However, the use of fresh air fans to input fresh air into the room on the one hand will occupy indoor space, and on the other hand, fresh air fans need to be purchased separately, which increases the user's use cost. However, in the prior art, the integrated air conditioner, taking the window air conditioner as an example, does not have an air conditioner product that can realize both the air conditioning function and the function of a fresh air blower. The existing solution is only to open one on the indoor side of the window air conditioner. Small holes (too large aperture will affect the cooling and heating effect and increase energy consumption), so that a small amount of fresh air can enter the room, the ventilation effect is poor, and the ventilation effect of the dedicated fresh air blower cannot be compared.

The cooling and heating principles are the same as those in the prior art without detailed explanation, and throttling devices and four-way Valves, pipelines and compressors are the same as in the prior art, and are omitted in Figure 3; the indoor side panel 1500 is installed on the indoor side 1211 of the housing 1210, and is provided with the indoor air inlet 1213 and indoor air outlet 1214. Corresponding air outlets, the outdoor side panel 1600 is installed on the outdoor side 1212 of the housing 1210, and there are air openings corresponding to the outdoor air inlet 1215 and the outdoor air outlet 1216. The indoor side panel 1500 and the outdoor side panel 1600 are used as an air conditioner integrated machine. The main appearance components of the 1000 have the same structure as the prior art, and will not be repeated. The indoor side panel 1500 and the outdoor side panel 1600 and the housing 1210 of the air duct device 1200 together form the outer shell of the air conditioner 1000.

Different from the prior art, referring to Figs. 5 and 6, in conjunction with Figs. 3 and 4, the air duct device in this embodiment further includes a partition 1230 to realize that the air conditioner 1000 has a fresh air function at the same time, and Can switch with air conditioning function. Specifically, the partition 1230 is rotatably disposed in the air duct 1220, and the partition 1230 has a first position A and a second position B; at the same time, when the partition 1230 is in the first position A, as shown in FIG. 5, In this embodiment, the partition 1230 is perpendicular to the length of the housing 1210, the indoor air inlet 1213 is connected to the indoor air outlet 1214, the outdoor air inlet 1215 is connected to the outdoor air outlet 1216, and the indoor air inlet 1213 is connected to the outdoor air inlet. The air inlet 1215 is disconnected, the indoor air inlet 1213 is disconnected from the outdoor air outlet 1216, the indoor air outlet 1214 is disconnected from the outdoor air inlet 1215, and the indoor air outlet 1214 is disconnected from the outdoor air outlet 1216, so that the air The duct 1220 is divided into an indoor side part 1221 and an outdoor side part 1222 by a partition 1230. The air flow in the two air ducts does not affect each other, and the air flow direction is shown by the hollow arrow in Figure 5, which satisfies the realization of the air conditioning function of the air conditioner itself. The partition 1230 is equivalent to, for example, the central partition of an existing window air conditioner; when the partition 1230 is in the second position B, as shown in FIG. 6, the partition 1230 rotates parallel to the housing 1210 in this embodiment.
