Embodiment Construction

[0020] figure 1 A domestic appliance 10 is shown in which a first fluid circuit 20 circulates a fluid and a second fluid circuit 34 circulates said fluid. The first fluid circuit 20 of the domestic appliance 10 has a compressor 22 which is connected in series with a bypass 28 , wherein the bypass 28 has at least one valve. The at least one valve can be designed as a solenoid valve or also as a bistable or bidirectional valve. The first fluid circuit 20 is connected in parallel to the second fluid circuit 34 , wherein the second fluid circuit 34 forms the actual fluid circuit of the domestic appliance 10 . In the second fluid circuit 34 , the original cooling circuit, the compressor 22 , the evaporator 24 and the liquefier 26 are connected in series.

[0021] The bypass 28 in the first fluid circuit 20 can be actuated by means of the control device 30 , in particular at the start of operation of the domestic appliance 10 or during operation through at least one predetermined ...

Abstract

The invention relates to a household appliance (10) having a first fluid circuit (20) and a second fluid circuit (34) for circulating fluid during operation of the household appliance (10), wherein, acompressor (22) for compressing fluid is provided in the first fluid circuit (20) and the second fluid circuit (34), the compressor having a low pressure side (38) and having a high pressure side (36). A bypass (28) is also provided in the first fluid circuit (20), wherein, in order to achieve vibration reduction and / or noise reduction during running start or during operation of a predetermined rotational speed range, the compressor (22) is capable of bridging with the bypass (28) to counteract the building of the pressure on the high pressure side. Furthermore, the invention relates to a method for operating a household appliance (10) in a manner that reduces vibration and / or noise.

Description

technical field [0001] The invention relates to a household appliance having a first fluid circuit and a second fluid circuit for circulating a fluid during operation of the household appliance, and to a household appliance for reducing vibration and / or noise A method of operating in a reduced manner. Background technique [0002] Compressors are used in many household appliances for compressing fluid media, in particular coolants. Compressors, which require sufficiently good oil lubrication, are known, for example, for use in heat pumps. However, precisely in domestic refrigeration appliances, such as refrigerators, the cooling circuit with the heat pump does not run without interruption. In the case of a fluid circuit (or cooling circuit) start-up, the compressor is started. In this starting state, however, the compressor does not have good oil lubrication, ie the oil is not distributed throughout the compression space of the compressor precisely at the start of operati...
