Embodiment Construction

[0029] and figure 1 and figure 2 as well as Figure 5 to Figure 8 Correspondingly, the blower device 1 according to the invention has a housing 2 and has a motor 4 mounted in the housing 2 via a motor mount 3 (only in figure 1 and figure 2shown in the middle figure), in particular an electric motor, where the engine mount 3 is held on the housing 2 by the arm 5, so as to allow the movement of the motor 4 relative to the housing 2, but to dampen and thus reduce the transmission of vibrations from the engine 4 to the housing 2 . A blower device 1 of the described type can be used, for example, in a heating, ventilation or air conditioning system 14 , in particular in a motor vehicle. According to the invention, it is now the case that the motor mount 3 , the arm 5 and the housing 2 are formed as an integral injection-molded part, whereby the motor mount can be produced not only inexpensively but also simply in terms of production. Furthermore, each arm 5 has a first porti...

Abstract

A blower device may include a housing and a motor mounted in the housing via a motor holder. The motor holder may be held on the housing via a plurality of arms such that a movement of the motor relative to the housing is permitted and a transmission of vibrations of the motor to the housing is dampened. The motor holder, at least one arm of the plurality of arms and the housing may be configured as a unipartite plastics injection-moulded part. Each arm of the plurality of arms may have a plurality of sections. The plurality of sections may include a first section connected to the motor holder, a second section angled relative to the first section, and a third section angled relative to the second section and connected to the housing.

Description

technical field [0001] According to the preamble of claim 1 , the invention relates to a blower device having a housing and having a motor mounted in said housing via a motor mount. The invention also relates to a heating, ventilation or air-conditioning system, in particular a heating, ventilation or air-conditioning system in a motor vehicle, having at least one such blower device. Background technique [0002] EP1844965B1 has disclosed a general blower arrangement having a housing and having a motor mounted in said housing by means of a motor mount held on the housing by arms to allow movement of the motor relative to the housing, But at the same time, the transmission of vibrations from the engine to the casing is suppressed. Here, the arm is formed in the manner of a fastening beam and is mechanically connected to, ie mounted on, the housing. [0003] However, a drawback of the blower devices known from the prior art is their relatively cumbersome manufacture and the ...
