CN-224215536-U - Middle frame structure and air conditioner

Abstract

A middle frame structure and an air conditioner relate to the technical field of electric appliances. The middle frame structure comprises a middle frame and a first reinforcing structure, wherein the middle frame is provided with a mounting part used for mounting a detection component, the first reinforcing structure is arranged on the middle frame and located on one side of the middle frame facing to the detection component in the detection signal receiving and transmitting direction, and an avoiding part is arranged on one side of the first reinforcing structure facing away from the middle frame and used for avoiding detection signals received and transmitted by the detection component. The first reinforced structure is arranged on the middle frame, and plays a role of a reinforcing rib to improve the overall structural strength of the middle frame. When the first reinforced structure is arranged in the area where the middle frame possibly interferes with the detection signal, when the detection component receives and transmits the detection signal, the avoidance notch of the first reinforced structure is used for avoiding the detection signal received and transmitted by the detection component, the condition that the first reinforced structure shields the detection signal is reduced, the detection range of the detection signal is increased, and therefore the detection precision of the detection component is improved.

Description

Middle frame structure and air conditioner Technical Field The disclosure relates to the technical field of electric appliances, in particular to a middle frame structure and an air conditioner. Background Along with the improvement of life quality, the functional requirement of people on the air conditioner is no longer satisfied with the traditional refrigeration and heating functions, and the intelligent degree of the air conditioner is provided with higher requirements. In order to meet the intelligent demands of people on air conditioners, integration of more detection devices in the air conditioners is a trend. The integrated detection device is used for collecting and detecting surrounding environment information, so that detection data is provided for intelligent control of the air conditioner. Accordingly, how to ensure that the integrated detection device provides accuracy of detection data is also a problem to be solved in the art. Disclosure of utility model The disclosure provides a middle frame structure and an air conditioner. According to a first aspect of the present disclosure, there is provided a middle frame structure comprising: the middle frame is provided with an installation part for installing the detection component; the detection device comprises a middle frame, a detection component, a first reinforcing structure and a second reinforcing structure, wherein the first reinforcing structure is arranged on the middle frame and is positioned on one side of the detection component facing to the receiving and transmitting direction of the detection signal, and an avoidance part is arranged on one side of the first reinforcing structure, which is away from the middle frame, and is used for avoiding the detection signal received and transmitted by the detection component.
