Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, fig. 2 and fig. 3, the present embodiment discloses a cab defrosting heater, which is arranged in bilateral symmetry; thus, two air inlets and two air outlets are symmetrically formed on one cab defrosting heater; the defrosting heater of the cab comprises a shell 1, a heating element 2, an air inlet 3 and an air outlet 4; an air inlet 3 is arranged at the top of the shell 1; a heating element 2 is arranged in the cavity of the shell 1; an air outlet 4 is arranged at one side of the shell 1; such structure adopts the mode of electrical heating to set up the wind gap, utilize the mode of heated air to defrost, can solve like this and adopt article such as wiper to get rid of among the prior art, though feasible, but more troublesome, what clear away moreover is not very thorough, the severe case of frosting still can damage the wiper, if adopt the manual mode of getting rid of, the driver need stop technical problem such as work on hand, realize automatic defrosting.
Referring to fig. 1, fig. 2 and fig. 3, the shell 1 has an upper-layer structure and a lower-layer structure, and an air inlet 3 is formed in the upper layer of the shell 1; the lower layer of the shell 1 is a cavity; the upper layer edge of the shell 1 is connected with the lower layer edge of the shell 1 through rivets; a gasket 5 is arranged between the upper edge of the housing 1 and the lower edge of the housing 2, so that; air leakage cannot occur between the upper layer edge of the shell 1 and the lower layer edge of the shell 1, and the product is guaranteed to be used in a ventilating mode after being heated normally.
Referring to fig. 1 again, in the present embodiment, two ends of the heating element 2 are respectively fixed on the housing 1; the heating elements 2 are connected in parallel and then connected to a power supply on the connection terminals 5.
The heating elements 2 in this embodiment are wire wound resistors, 4 in number. In order to prevent the heating element 2 from overheating and adjust the temperature in the using process, a temperature controller 7 and a high-temperature-resistant switch 8 are connected outside the shell 1; according to the electrical connection scheme of the present embodiment shown in fig. 4, a temperature controller 7 and a high temperature prevention switch 8 are connected in series with the heating element 2 in an electrical circuit for preventing overheating of the heating element 2 and for temperature regulation of the heated air.
As a preferred embodiment of the present invention, it is obvious to those skilled in the art that the present invention is not limited to the details of the above-described exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention, and that the scope of the present invention is also encompassed by the present invention.
