The present invention provides a pet drying box, which uses an electrical control device in conjunction with techniques of frame unitization and modularization to realize the rationalization of production procedure, service, and maintenance, inexpensive equipment expansion, environmental improvement, and energy-saving measures, etc. The electrical control device (1) can perform regulations of air volume and temperature by means of a temperature sensor, and control the number of rotations of a fan motor by means of a humidity sensor, this invention is provided with a partition plate for separating the electrical control device (1) and an opening portion of the side surface of a frame (14). At a substantially central portion of the partition plate, there is mounted a filter-attached window, and a warm air discharge port is provided at the bottom of the partition plate. The front side of the frame (14) is configured with a pet door (19), and a side plate (23) is mounted at the side surface on the opposite side of to the opening portion. By enabling the electrical control device (1) and the frame (14) to generate a connection at the opening portion, assembly and detachment can be easily carried out.本發明提供一種寵物用烘乾箱,其使用電氣控制裝置與框體的單元化‧模組化技術,而加以實現生產步驟的合理化、服務‧維護的合理化、設備擴展的低廉化、環境改善、節能對策等。電氣控制裝置(1)係具備有藉由溫度感測器而進行風量‧溫度調整且藉由濕度感測器而控制風扇馬達旋轉數的功能,設置有將電氣控制裝置(1)與框體(14)之側面開放部之間加以隔開的隔板,在上述隔板的大致中心部,安裝有附過濾器之窗,而在上述隔板的下方,設置有暖風排出口,框體(14)係在其前面,安裝有用於寵物的門(19),且在與上述側面開放部為相反側的側面,安裝有側板(23),並藉由使電氣控制裝置(1)與框體(14),在上述側面開放部產生連結,而能夠簡單地進行組裝及分解。1‧‧‧電氣控制裝置14‧‧‧框體19‧‧‧門23‧‧‧側板
