A bladeless fan for heating and cooling with a horizontally arranged annular air duct

Abstract

This utility model discloses a bladeless fan with a horizontally arranged annular air duct for both heating and cooling. It includes a main housing with an air inlet on one side. Inside the main housing is a fan with its air inlet aligned with the air inlet. A baffle assembly for balancing the airflow on both sides is located at the upper end of the annular air duct. This horizontal arrangement, aligning the fan's air inlet with the air inlet on the main housing, minimizes the space occupied by the fan installation, saving more space for other components and structures. This results in a smaller, more compact bladeless fan, improving space utilization. The cooperation of baffles A and B ensures that even if the airflow from the horizontally arranged fan's outlet into the left and right annular air ducts differs, the baffles can buffer the side with the stronger airflow, maintaining uniform airflow from both sides and preventing wind noise caused by differences in airflow strength.

Description

Technical Field

[0001] This utility model belongs to the technical field of bladeless fans for both heating and cooling, and specifically relates to a bladeless fan for both heating and cooling with a horizontally arranged annular air duct. Background Technology

[0002] Electric fans are common household appliances in summer. Traditional electric fans use electric motors to drive the blades to rotate and generate high-speed airflow. However, the high-speed rotation of the blades also poses certain dangers. As a result, bladeless fans have emerged on the market. In bladeless fans, the high-speed airflow generated by the base is forced into the head by high pressure and finally ejected from the nozzle. This makes it difficult for users to touch the blades and other rotating parts, making it safe to use and easy to clean. In order to provide heating, bladeless fans that can be used for both heating and cooling have also been designed.

[0003] The existing bladeless fan has the fan and air inlet direction offset from each other in order to ensure that the air delivered to the annular air duct can be evenly distributed on both sides of the annular air duct and to avoid wind noise caused by different wind speeds on both sides. However, this fan layout causes the fan to occupy a lot of space inside the casing, thereby occupying the installation space of other parts. As a result, the overall casing size has to be increased, making the overall bladeless fan larger and the space utilization rate low. Utility Model Content

[0004] The purpose of this invention is to provide a bladeless fan with a horizontally arranged annular air duct for both heating and cooling, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bladeless fan with a horizontally arranged annular air duct for both heating and cooling, comprising a main housing, an air inlet on one side of the main housing, a fan arranged inside the main housing with its air inlet end aligned with the air inlet, an annular air duct at the upper end of the main housing, the air outlet end of the fan communicating only with the annular air duct via a guide plate, an electric heater installed inside the annular air duct, a pair of air outlets symmetrically distributed on one side of the annular air duct, and a baffle assembly at the upper end of the annular air duct for balancing the air volume on both sides.

[0006] Preferably, the main housing is provided with a detachable humidifier, the main housing is formed by splicing together a splicing housing A and a splicing housing B, and the annular air duct is formed by splicing together the upper ends of splicing housing A and the upper ends of splicing housing B.

[0007] Preferably, the baffle assembly includes a pair of baffles A symmetrically arranged at the upper end of the annular air duct, and a baffle B located at the center of the top of the annular air duct. The pair of baffles A are symmetrically distributed and fixed at the upper end of the splicing shell A, and the baffles B are distributed and fixed at the top of the splicing shell B.

[0008] Preferably, the bottom of the main housing is provided with a base that can rotate relative to it, and the bottom of the main housing is provided with a swing servo drive module that can drive the base to rotate relative to it.

[0009] Preferably, the edge of the guide plate is sealed and fitted to the inner surface of the main housing, and the opening size of the guide plate matches the size of the fan outlet.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] By aligning the air inlet of the fan with the air inlet on the main casing in a horizontal arrangement, the space occupied by the fan installation can be minimized, thereby saving more internal space to arrange and install other parts and structures, thus ensuring that the entire bladeless fan is smaller in size, more compact in overall design, and improves space utilization.

[0012] By symmetrically arranging a pair of baffles A at the upper end of the annular air duct and designing a baffle B in the center of the top of the annular air duct, the cooperation of baffles A and B can ensure that even if the air force of the horizontally arranged fan air supply ends entering the annular air duct on both sides is different, the baffles can buffer the annular air duct on the side with greater air force, so that the air outlet on both sides of the annular air duct can still remain uniform and there will be no wind noise caused by the difference in the strength of the air force on both sides.
