COMPRESSOR

Abstract

A compressor includes a compressor housing, a fastening device arranged on the compressor housing, and a support device, connected to the fastening device, for a temperature sensor, the support device being designed to hold, by pressing, the temperature sensor against a wall of the compressor housing. The support device has, for multiple connection to the fastening device, at least two sections, located on different sides of the temperature sensor, wherein, when the compressor is used as intended, the temperature sensor is designed to brace against the compressor housing from below.

Description

[0010] In which

[0011] FIG. 1 shows the compressor with a support device according to a first exemplary embodiment in a side view;

[0012] FIG. 2 shows the support device of the compressor according to FIG. 1 in perspective;

[0013] FIG. 3 shows the support device of the compressor according to a second exemplary embodiment;

[0014] FIG. 4 shows the support device of the compressor according to FIG. 3 in perspective.

[0015] The compressor according to the invention consists of a compressor housing 1, a fastening device 2 arranged on the compressor housing 1, and a support device 3 connected to the fastening device 2 for a temperature sensor 4, wherein the support device 3 is designed to press the temperature sensor 4 against a wall 1.1 of the compressor housing 1, see FIG. 1.

[0016] It is thus essential for the compressor according to the invention that the support device 3 has at least two sections 3.1, 3.2 located on different sides of the temperature sensor 4, for repeated connection to the fastening device 2, wherein, when the compressor is used as intended, the temperature sensor 4 is designed to be braced against the compressor housing 1 from below, see FIGS. 1 to 4.

[0017] In this case, it is preferred that the fastening device 2 is designed in the form of at least two, preferably three, lugs which protrude from the compressor housing 1 and which are arranged to be distributed over the periphery thereof.

[0018] It is also preferred, when the compressor is used as intended, that the temperature sensor 4 is preferably designed to be braced against the compressor housing 1 from below, preferably against the wall 1.1 forming a base of the compressor, by means of the sections 3.1, 3.2 which run at least partially above the fastening device 2. In this manner, the position of the temperature sensor 4 on the compressor housing 1 is clearly defined and leads to reproducible and comparable measurement results.

[0019] The support device 3 is preferably also designed to be suspended on the fastening device 2. Similarly, it is preferred, when the compressor is used as intended, that the fastening device 2 is arranged above the temperature sensor 4. This permits a particularly simple assembly of the support device 3 on the compressor.

[0020] It is also preferred that the support device 3 is designed to be stamped from a metal sheet and to be produced by re-shaping, see FIGS. 1 and 2. Alternatively, it is preferred that the support device 3 is designed to be produced from wire, see FIGS. 3 and 4. In these cases, therefore, the support device can be produced particularly simply and cost-effectively, but without losing its effectiveness.

[0021] Additionally, regarding the construction of the support device 3 it is preferably provided that at least one of the sections 3.1, 3.2 has an opening 3.3 for receiving the fastening device 2 (see FIGS. 1 to 4) and/or that at least one of the sections 3.1, 3.2 is designed as a hook which is open on one side (see FIGS. 3 and 4). Moreover, it is preferred that the sections 3.1, 3.2 are designed as free end sections of the support device 3. It is also preferred, when the compressor is used as intended, that the sections 3.1, 3.2 are designed to run horizontally on the contact region with the fastening device 2. This permits an effective hold of the support device 3 on the fastening device 2 and prevents the support device 3 from slipping off.

[0022] It is also preferred that the temperature sensor 4 is designed to be bar-shaped. Additionally, the temperature sensor 4 is preferably designed to be fastened by a receiving element 5 to the support device 3. In this case, the receiving element 5 preferably has a receiving slot 5.1 for the temperature sensor 4, the receiving slot being adapted to the shape of the temperature sensor 4 and being open toward the wall 1.1. The measure that the receiving slot 5.1 is open toward the wall 1.1 makes it possible for the temperature sensor 4 to bear directly, i.e. without an intermediate space, against the compressor housing 1, which in turn improves the temperature measurement. In this case, the receiver element 5 is preferably formed from a material with a thermal conductivity of less than 0.1 W/(mK), in particular from plastics. In this regard, see also https://de.wikipedia.org/w/index.php?title=W%C3%A4rmeleitf%C3%A4higkeit&oldid=203331633.

[0023] It should also be mentioned that the above measure, namely that the support device 3 is to be connected to the fastening device 2, not only describes compressors in which the support device 3 is positioned partially on the fastening device 2 as shown in the figures. Embodiments are also encompassed thereby in which the support device 3 and the fastening device 2 are designed to be connected together by a connecting element, such as for example screws or bolts.

[0024] The compressor according to the invention according to the exemplary embodiment of FIGS. 1 and 2 functions as follows:

[0025] Initially the temperature sensor 4 is inserted into the receiving slot 5.1 of the receiving element 5. Now the support device 3, on which the receiving element 5 is located, is pulled with its sections 3.1 and 3.2 over the fastening device 2 such that the tabs of the fastening device 2 come to rest in the openings 3.3 of the support device 3 and the temperature sensor 4 comes into contact with the wall 1.1 of the compressor housing 1. In this manner, each time the carrier element 4 is assembled, the temperature sensor 4 is automatically fitted in the correct position on the compressor housing 1 and can deliver reliable measurement results. Additionally, this effect is ensured by the use of a carrier element 4 which can be produced simply and cost-effectively.
