Description

Fresh air conditioner indoor unit and fresh air conditioner

Technical Field

The utility model relates to the field of fresh air conditioners, in particular to an indoor unit of a fresh air conditioner and the fresh air conditioner.

Background

At present, a plurality of air conditioning products in the market are all carried with a fresh air function so as to strengthen the circulation flow of indoor and outdoor air and improve the indoor air quality. However, the fresh air conditioner has a common problem, namely condensation. When excessive condensed water appears in the air conditioner, the service life of the fresh air conditioner is influenced, and the quality of the fresh air blown out by the fresh air conditioner is greatly reduced.

The condensation prevention scheme which is commonly used at present is to paste a large amount of sponge on the outer surface of the fresh air part for heat preservation so as to achieve the effect of preventing the condensation. However, the sponge cannot be adhered to the inner surface of the fresh air component, and under certain specific conditions, for example, after cooling is started in summer for a period of time, the temperature of the inner surface of the fresh air component is low, if the fresh air is started at this time, the humid and hot air of the outdoor side flows into the fresh air component, and after contacting the inner surface of the low-temperature fresh air component, a small amount of condensation water still can be generated, and the condensation water flows out and drops along the fresh air duct, so that the user experience is affected, and even the air conditioner fails.

Disclosure of Invention

In order to solve the technical problems, the utility model aims to provide an indoor unit of a fresh air conditioner and the fresh air conditioner, wherein a water guide way and a water storage area are arranged at an air outlet of a fresh air part and are used for guiding and storing condensed water formed in the air channel, so that the condensed water is prevented from flowing out of the air outlet.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

the utility model provides a fresh air conditioner indoor unit, includes interior machine main part and sets up the new trend part in the interior machine main part, the new trend part includes new trend spiral case, wind wheel, new trend box, filter core box and new trend lid, the new trend spiral case is installed in one side of new trend box, cooperates between new trend spiral case and the new trend box and forms the new trend wind channel, and the wind wheel is installed in this new trend wind channel, the new trend lid is installed at the opposite side of new trend box, the filter core box is installed between new trend lid and new trend box; the fresh air channel is characterized in that a water diversion channel is arranged at the air outlet of the fresh air channel, the water diversion channel is arranged in a V shape, a water storage area is arranged at the front end of the water diversion channel, and condensed water is led to the water storage area by the water diversion channel.

The temperature difference between the inner surface of the fresh air part and the outdoor fresh air generally reaches balance within 10 minutes after the fresh air is started, so that condensed water on the inner surface of the fresh air part is generally slowly formed within 3-10 minutes after the fresh air is started, and the water quantity is small, and therefore the problem that the condensed water flows out of an air outlet can be solved by adopting a mode of storing the condensed water. After the comdenstion water of new trend part internal surface forms, can outwards flow along with the wind channel, after the drop of water runner water guide, can flow into the water storage along the water guide, because the temperature of new trend is the ambient temperature of outdoor side, this ambient temperature is generally greater than 25 ℃, consequently in the new trend constantly blows over the water storage, the comdenstion water in the water storage can evaporate fast, along with the new trend is discharged indoor side, can not remain in the water storage.

Preferably, the water diversion channel comprises a first channel and a second channel, wherein the first channel and the second channel are arranged in a V shape, and the front end of the first channel is communicated with the front end of the second channel through a water storage area; the first channel is arranged on a first bottom plate of the fresh air volute, one part of the second channel is arranged on the first bottom plate of the fresh air volute, the other part of the second channel is arranged on a second bottom plate of the fresh air box, and the water storage area is arranged on the first bottom plate of the fresh air volute; or, a part of the first channel is arranged on the first bottom plate of the fresh air volute, the other part of the first channel is arranged on the second bottom plate of the fresh air box, the second channel is arranged on the second bottom plate of the fresh air box, the water storage area is arranged on the second bottom plate of the fresh air box, and the surface of the first bottom plate is flush with the surface of the second bottom plate. Because the water storage area is completely arranged on the first bottom plate or the second bottom plate, the seam between the first bottom plate and the second bottom plate is positioned on the first channel or the second channel, and therefore water in the water storage area cannot flow out from the seam between the first bottom plate and the second bottom plate.

Preferably, the first bottom plate and the second bottom plate are in plug-in fit.

Preferably, a groove is formed in one side, close to the fresh air box, of the first bottom plate, a convex rib is arranged on one side, close to the fresh air volute, of the second bottom plate, and the first bottom plate is connected with the second bottom plate through insertion and matching of the groove and the convex rib.
