Problems solved by technology

[0004] Although such a solution can increase the wind pressure of the range hood to a certain extent, in practical applications, such a series fan system requires a large change in the circuit structure of the range hood, and the design cycle is long, which is not conducive to large-scale promotion. application

Embodiment Construction

[0056] As mentioned in the background art, in existing range hoods, a series fan system is commonly used to increase the air pressure of the range hood, so as to better improve the exhaust air volume of the range hood and optimize user experience.

[0057] For the existing series fan system used for range hoods, due to the increase in the number of fans, manufacturers need to add a set of corresponding control circuits to control each fan in the range hood system while adding fans to the range hood. The working status of the fan; or, some manufacturers choose to redesign the control chip, so that the control chip that originally only needs to control one fan can control two fans at the same time.

[0058] However, no matter which of the above solutions is adopted, the circuit structure of the range hood needs to be greatly improved, and the design cycle is long, which is not conducive to large-scale popularization and application.

[0059] In order to solve the above technical...

Abstract

A range hood and its series fan system, control method, connectors, and fan system, the series fan system for range hoods includes: a first fan; a second fan; a connector, the two ends of the connector are respectively connected to the second The air outlet end of the first fan and the air inlet end of the second fan; the connecting piece includes a control switch, which is used to detect the fluid characteristics of the detection points in the connecting piece, and control the working state of the second fan according to the fluid characteristics, so that the second The blower opens with the opening of the first blower, and closes with the close of the first blower; the connecting piece also includes a throat, the opening cross-sectional size of the throat is smaller than the opening cross-sectional size of other parts of the connecting piece, and the detection point is located between the throat and Between the outlet ends of the first fan. The technical solution provided by the invention can simplify the installation method of the second fan without changing the first fan, and the two fans can work in linkage, and can effectively improve the working efficiency of the entire series fan system.

Description

technical field [0001] The invention relates to the field of household electrical appliances, in particular to a range hood, its serial fan system, a control method, a connecting piece, and the fan system. Background technique [0002] As the two key indicators to measure the performance of a range hood, wind pressure and exhaust air volume largely determine whether a range hood is popular with the public. As a result, when designing a range hood, manufacturers of range hoods will take wind pressure and exhaust air volume as the two major design reference factors, hoping that the final designed fan system will have a higher wind pressure, and, when the wind pressure is determined, In the case of a large exhaust air volume. [0003] In order to increase the wind pressure, an existing technical solution is to connect two blowers in series and place them in the range hood as a whole. However, in the existing series fan system, the on / off control of the two fans is realized th...
