Description

  The present invention relates to a box dryer for a pet that integrates a casing (drying chamber) for housing and drying a pet and an electric control device, and particularly improves the efficiency of cooling, ventilation, and heat exchange of electronic circuits and motors. The present invention relates to an electric control device for a pet box dryer.

  The blower motor incorporated in the electric control unit of the conventional pet box dryer has a cooling fan attached to reduce the temperature rise of the motor, a propeller fan attached to the blower motor shaft, or an electric fan. Although the motor is cooled by providing ventilation holes on the back of the control unit case, there are disadvantages such as an increase in cost and a low cooling effect (due to natural convection).

  In addition, the warm air sent into the drying chamber evaporates the moisture of the dried body (wet pet), increasing the humidity and decreasing the drying speed. Therefore, a large opening is provided around the drying chamber door for drying. It takes outside air into the room and discharges hot and humid air. For this reason, when used outdoors in cold regions, the temperature did not rise to a predetermined temperature and could not be put into practical use. Moreover, there existed a fault that the hair removal of a dry body scattered in a working chamber.

  Further, heat generated from the hot air blowing motor and the control circuit is discharged into the work chamber, and there is a drawback that a large amount of electricity is required for cooling the chamber.

  Further, the heat ray treatment released from the heater was not satisfactory.

  On the other hand, the following inventions have been proposed for pet drying apparatuses in which a drying module is installed in the drying chamber.

  Utility Model Registration No. 3166426 (Patent Document 1) is intended to dry a pet in a convenient and speedy manner by allowing the entire body of a pet to be dried for a pet that has been put into a storage space after showering. Including a box body and a drying module, and a housing space provided with a door inside the box body, and an air discharge duct for discharging and sending air to the outside is provided on one side of the housing space. Is attached to the box, has a storage chamber for storing the drying device, and is provided with an inlet duct for allowing external air to enter on the side of the storage chamber, and sends heat energy to one side of the drying device. There is an outlet, and a control valve for a conversion operation in the delivery direction is connected to the outlet, an extension pipe for performing a drying operation outside the pair of boxes is connected to one side of the control valve, and to the other side And wherein the inlet tube is provided which communicates with the housing space of the box "pet drying apparatus" is proposed.

  However, the above-described pet drying apparatus does not disclose cooling the blower motor or the control circuit with outside air. Nor is it disclosed that hot air from which hair has been removed by a filter is discharged.

  The applicant of the present application has developed a pet box dryer that is inexpensive and can be easily assembled by unitizing the electrical control device and the housing (drying chamber) and modularizing the housing. Obtained patent rights (Japanese Patent No. 5478763, Patent Document 2)
