Description

Technical Field

[0001] The invention relates to the field of air conditioning, and in particular to a ceiling air conditioner with an electric heating function. Background Art

[0002] At present, for air conditioners equipped with electric heating, in order to ensure the safe operation of the electric heating, a sensor for collecting the electric heating temperature is usually installed on the electric heating, and a controller is used to control the operation of the electric heating according to the collected temperature to prevent accidents from happening to the electric heating and cause hazards such as fire. However, the existing sensors equipped on the electric heating are complex and have low safety, and the electric heating is placed in the straight section of the evaporator, occupying a large amount of space. Therefore, it is of great significance to study how to optimize the setting of the electric heating device in the ceiling machine in order to improve the safety of the installed electric heating device.

[0003] Existing embedded air conditioners often use electric heating devices to be set on the straight section of the evaporator, and the electric heating devices are directly set on the bottom inside the air conditioner shell, which easily causes the electric heating devices to occupy a large space and affect the arrangement of other components inside the air conditioner shell.

[0004] In addition, patent CN109780637A mentions a heating component, an electric heating device and a ceiling machine, wherein the heating component includes a bracket, a PTC heater, a mounting frame, a first fuse and a thermostat, wherein the bracket is used to be installed on a mounting plate, the PTC heater is installed on the bracket, the mounting frame is installed on the bracket and is located on the surface of the PTC heater, the first fuse and the thermostat are installed on the mounting frame, and the first fuse and the thermostat are electrically connected to the PTC heater; the electric heating device includes a mounting plate and a plurality of the heating components installed on the mounting plate, and the bracket is installed on the mounting plate, which can solve the problem of complex form and low safety of the existing electric heating sensors, but the layout of the wire pressing plate and the electric heating device is relatively complicated. When the wire pressing plate needs to be disassembled and re-wired, the setting position of the electric heating device is likely to affect the disassembly and wiring of the wire pressing plate, thereby reducing the disassembly and assembly efficiency inside the ceiling machine.

[0005] In patent CN208579412U, a ceiling machine is mentioned, comprising: a shell; an airflow driving member, at least a part of which is arranged in the shell; a heat exchanger, at least a part of which is arranged in the shell, and the heat exchanger surrounds the airflow driving member; a heating member, at least a part of which is arranged in the shell, and the heating member surrounds the airflow driving member, and the heating member is connected to a wiring harness; a controller, the controller is connected to the heating member; a wiring harness positioning member, the wiring harness positioning member is connected to the shell, and the wiring harness is positioned by the wiring harness positioning member; through the arrangement between the components, the impact on the air outlet efficiency can be reduced and the safety performance can be improved, but the wire pressing plate in this application is arranged below the airflow driving member, and the heat exchanger surrounds the airflow driving member, which still easily causes the problem of inconvenient disassembly and assembly of the wire pressing plate.
