Disinfection or cleaning liquid can be used to de-infect the actual cooling device. For example, it can be removed and used to clean a freezer. Furthermore, the immersion cooler of a corresponding device, but also milking goggles or the like. getting cleaned. Finally you can use the container on this Purpose also train so that you can use the immersion cooler, the milking harnesses or the like. can bring directly into him. These objects can then even be stored in the container as long as they are not needed.

Finally, the container can also be used to produce hot water. This can also be done in many cases in connection with the dairy industry.

According to the main patent, Bs are already various means to regulate the temperature in the liquid container Provided, such as in particular slide, through which the condensate or air flow can additionally bypass the liquid container and also slide, through which the container is additionally heated by the radiant heat of the cooling machine can be.

However, there are cases when these means of regulation the temperature in the liquid container is not sufficient. In particular, when the outside temperature is lower, for example at 3 C outside temperature, the pressure of the compressed air drops

Coolant so far that in the part of the coolant line provided for heating the liquid container the desired temperatures can no longer be maintained can. It must be taken into account that a pressure drop on 7 * there is about a temperature drop to 35 ° in the KÜhleiit parts! tion corresponds. At 8 ° outside temperature, however, it drops Pressure when using a normal capacitor to 5 atU, so that with the compressed coolant it is no longer possible to heat the liquid container. I.

According to the invention, these disadvantages are now eliminated prevented the temperature of the compressed coolant used to heat the liquid container from being adjustable by changing the condenser air flow.

According to the invention, this can be done by changing the running time or the running speed of the fan in order to generate the condenser air flow. To this Way, the pressure of the compressed coolant and thus also its temperature can exactly correspond to the desired Height can be adjusted so that the liquid in the too. heating container to the desired one Temperature can be brought, but above all disruptive influences of the outside temperature can be switched off.

You can also do it in addition to or independently of the regulation the fan running time or speed proceed as follows, that the compressed coolant can be conducted to the cooler by bypassing the condenser. So you can with it switch off the condenser from the coolant circulation. This can lead to an undesirable pressure drop, especially when the outside temperature is lower, and thus too much cooling of the compressed coolant. Self-understanding Both measures can be combined with one another.

Advantageously, the means of diverting the condensation process is used serving line attached a throttle valve. Through this throttle valve, the diversion For example, they can be closed when the outside temperature is higher and opened when the outside temperature is lower. Be ee then no further valves are required, because when the throttle valves are open because of the high resistance in the capacitor the entire coolant flow through the diversion

The invention is further characterized in that an otruck- or temperature-independent switching device is housed, whereby in the case of a regulation of the fan running time or speed, preferably a pressure-dependent Control unit is used while · in the case of bypassing the coolant, bypassing the condenser Temperaturmeß- or - © cfealtgerät is used.

According to the invention, the switching device controls the running time or speed of the fan and / or the position of the throttle valve in the bypass line.

A pressure of about 7 atü corresponds approximately to a temperature of 35 ° of the coolant and a pressure of 11 atti corresponds to a temperature of about 55 C. Since it is not practical to use a coolant with a lower. Temperature than 35 ° .umgekehrt for heating the FlüssigkeitsbehUlters to use and, at a pressure rise above 11 Kühlraaschdne atmospheres are claimed too would · is set the switching means so as to atmospheres at a pressure less than 7 and a temperature below 35 ° ^the The fan switches off or the throttle valve of the bypass line opens and, at a pressure above 11 atmospheres or a temperature above 55 °, the fan starts up or the throttle valve closes. *

On the drawings is an embodiment of the device shown according to the invention, for example.

A conventional cooling machine 1, coolant supply 2 and coolant discharge 3 work together with an immersion cooler k, the immersion spiral 5 of which surrounds an agitator 6. At the end of the container 7 to be cooled, a cover 8 is vox'go seen on the immersion cooler.

Uie KUhlmittÖllinien the immersion cooler are in housed in a protective tube.

The gas compressed in the cooling unit passes in the usual way through a cooler baw. Condenser 9 through which air flow is sucked by means of a fan "Io".

Before it passes through the cooler, the coolant line 3 is routed around a liquid container 11. One can of course also proceed in such a way that the line 3 is introduced into the container and through in the form of a snake guides the container through and out again. Finally, a spiral can also be attached to the bottom of a container or the container can be double-walled and the coolant can be passed through the jacket thus formed at the same time the cavity formed as a collector for the Use coolant.

The liquid container is equipped with an extraction cock 12 through which the content can be drained. Liquid or liquid heated in this way can also be used. a heated disinfectant or cleaning agent will be removed. '·

Openings which can be closed by slides 13 and 1h are provided in the housing of the device. If the slide 13 is closed and the slide valve is opened *, the

Through the air flow sucked in by the fan Io first past the condenser 9 , then on to the cooling wall 1 and the container 11, it exits through the opening of the sole lever Ik . The previously mentioned hit or cooling effect then occurs.

If the slide 13 is opened and the slide Ik is closed, which, as mentioned, happens in particular at high outside temperatures, the air does not sweep past the container 11, but exits directly. The slide 13 and Ik can also be combined with one another, so dall. a single slide closes one opening and releases the other opening. A thermostat can be used to regulate the slide.

Finally, baffles can be attached inside the housing in order to direct the air flow in the desired direction, which is advantageous, for example, if the liquid container cannot be attached directly above the refrigerator. Such sheets can also be designed as flaps and take over the task of the slide 13 and lh.

In the present full, the owner is not only through the Condensate heat and the airflow flowing past it also due to the radiated heat of the cool mask warmed up. This can lead to excessive warming.

Another very advantageous way of regulating the heating is provided by a heating device l6, which is in the form of an electric heating plate at the bottom of the Container arranged ibt. A switch 17 for this heating plate can be attached to the outside of the housing. The electrical power can be supplied from the cables that are already present in your housing.

Of course, an electrical heating device can also be looped around the container in a helical manner. The corresponding heating wire ο can then be used according to line 3 be arranged.

Of course, other than electrically operated ones can also be used Heating devices are used when there is a convenient way to do so under the given circumstances offers.

According to the invention, a switch 18 is installed in the cooling oil line 3 after it has been passed around or through the container 11, which switches the pressure and / or

There is also a bypass line 19 for the coolant provided that this coolant is immediately behind the Switch 18 bypassing the condenser 9 to the cooler feeds. A throttle valve 2o ″ is accommodated in this bypass line 19.
