CN202165330U - Cooling/heating bladeless fan - Google Patents

Abstract

The utility model discloses a cooling/heating bladeless fan, comprising a base, a fan body and a nozzle. The nozzle has an interior channel for receiving airflow from the base and an air exhaust. The nozzle is mounted on the base, which is provided with an air inlet. The fan body is mounted in the base and is arranged opposite to the air inlet. The cooling/heating bladeless fan is characterized by also comprising a cooling/heating unit which is arranged in the base and adjacent to the nozzle in such a manner to correspond to the fan body. The cooling/heating bladeless fan of the utility model has the beneficial effects that due to the addition of the cooling/heating unit, heated/cooled airflow can be generated, significantly prolonging the service lifetime of products; as the fan body is located in the base, noises are isolated, achieving the quiet effect; in addition, the cooling/heating bladeless fan has a beautiful appearance.

Description

A kind of cooling and heating does not have blade fan

Technical field

The utility model discloses a kind of fan assembly, is specifically related to a kind of indoor fan.

Background technique

Publication number is that the one Chinese patent application of CN 101424278A discloses a kind of no blade fan device that is used to produce air stream, and a kind of device that blade just can produce air-flow that need not is provided., existing technology can not produce the air stream of process heating or cooling but being merely able to produce common air-flow.

Summary of the invention

To the above-mentioned deficiency of mentioning of the prior art, the utility model provides a kind of air stream that can produce through heating or cooling.

The technological scheme that its technical problem that solves the utility model adopts is: a kind of cooling and heating does not have blade fan, comprises pedestal, fan and nozzle; Described nozzle comprises and is used to receive inner passage and the relief opening from the air-flow of pedestal that nozzle is installed on the pedestal; Described pedestal is provided with suction port; Described fan is installed in the pedestal, and fan is corresponding to the suction port setting; It is characterized in that: also comprise refrigerating and heating device, described refrigerating and heating device is arranged in the pedestal position near nozzle corresponding to fan.

Described nozzle is an annular solid.

Described refrigerating and heating device is a semiconductor refrigerating sheet.

Described refrigerating and heating device is the semiconductor refrigerating sheet that has electric heating wire.

Described refrigerating and heating device is an electric heating wire.

Also be provided with the switch that is used to control refrigerating and heating device and fan on the described pedestal.

Described a kind of cooling and heating does not have blade fan and passes through DC power supply.

Described a kind of cooling and heating does not have blade fan through the power supply of usb interface power supply.

The beneficial effect of the utility model is: owing to added refrigerating and heating device, can produce the air stream through heating or cooling, increase the service time of product greatly; Because fan is in the pedestal, noise is by isolated, and is very quiet; Profile is also very graceful.

To combine accompanying drawing and embodiment that the utility model is further specified below.
