The present embodiment is preferable that the undulated passage 6 is obtained by providing an undulated duct in the fourth housing 60, and the electric heater is installed on an inner wall of the undulated duct.

Other parts included in the air conditioner in this embodiment for achieving cooling and heating may be configured according to actual needs, and are not the focus of this embodiment, and therefore are not described in detail.

It should be noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
