Horizontal angle provided
The range of positive and negative angles is provided because the orientation depends on which main direction of movement the customer is moving along the refrigeration appliance, e.g., clockwise or counterclockwise. An orientation is used that causes the discharge direction to be co-directional with the direction of movement so that the customer does not feel the flow from the front or diagonally forward.
In order to increase the throw distance (Wurfweite) and to obtain the discharge direction for corner protection, a variant of the ventilation device proposes: the at least one fan has an outlet channel which is integrated in the fan or is connected to the fan.

Wherein the suction opening is oriented in the direction of a ground-near region in front of the refrigeration device and the discharge opening is oriented in the direction of a ceiling region of the refrigeration device opposite the ground-near region, so that cooling air discharged from the refrigeration device can be sucked off from the ground-near region and discharged on the ceiling region of the refrigeration device.
The suction device generates a suction flow by means of one or several ventilators of the ventilation device and sucks off this air which is discharged from the refrigerating device before it accumulates in the near-ground region spatially in front of the refrigerating device to form a certain "cold air lake" (in which a customer has to stand). The suction flow is discharged in the area of the top surface of the refrigerating appliance by the aforementioned ventilation device.
In an advantageous further development, the suction device can be integrated in the refrigeration appliance or can be arranged on the refrigeration appliance, while the following embodiments are particularly preferred: the suction channel is partly formed by the refrigeration device. The refrigeration appliance includes a housing enclosing a refrigerated compartment except for an open access side. The suction channel is preferably formed along this housing, so that the suction flow is guided on the outside along the bottom side and the rear wall side of the housing around the refrigerating device. The suction opening of the suction channel is preferably directed to the open access side and to the near-ground region in front of the refrigerating device.
In the case of a refrigeration system which operates independently, the components of the heat cycle which generate waste heat are arranged on the rear side of the refrigeration system. The following technical solutions of the suction device are advantageous: the suction channel is guided along the component generating the residual heat, so that a suction flow which is characterized by cooling air can pass by the component generating the residual heat, as a result of which the efficiency of the refrigerating appliance can be improved.
If the average orientation of the suction opening of the suction channel (mittlere Ausrichtung) is at an angle of 20 ° to 60 °, in particular 25 ° to 45 °, to the vertical height direction of the refrigerating appliance, the suction effect of the suction opening is positively influenced. The cold air stream discharged from the open access side can thereby be sucked off directly before it accumulates in the near-ground region in front of the refrigerating device. The special orientation facilitates the delivery of the cold air flow into the suction channel, while ensuring that air from the near-ground region is always also sucked in, in order to be able to counteract cold air which accumulates in front of the refrigerating device, if necessary, under the influence of external factors (for example during filling of the refrigerating device).
In a further aspect, the aspiration device further comprises a controller and a temperature sensor. The temperature sensor is preferably positioned on or in the suction channel in order to measure the temperature of the suction flow. The control unit can be used to regulate the suction flow delivered by the fan as a function of the measured temperature value of the suction flow and thus of the air in the near-ground region in front of the refrigerating device.
The invention also comprises a method for reducing the accumulation of cooling air discharged from a refrigeration device in the near-ground region in front of the refrigeration device, on the open access side of the refrigeration device, wherein a suction flow is generated by means of a suction device, the cooling air discharged from the refrigeration device being sucked off from the near-ground region by the suction flow and being discharged on the top surface region of the refrigeration device by a ventilation device.
In a refrigeration appliance having an open access side, a circulating flow is generated by means of a fan, which circulating flow is distributed along the access side towards the customer and around the refrigeration appliance housing defining the refrigerating compartment. The circulating flow may be directed through a heat exchanger and used as refrigerated air for the refrigerated compartment. However, since the fan can always deliver only a certain volume flow and an air exchange with ambient air also takes place in the region of the open take-off side, a certain amount of cooling air always comes out of the refrigerating device, which otherwise would accumulate in front of the refrigerating device. To the method, the utility model further provides the following preferred scheme: the suction flow is at least partially distributed parallel to the circulation flow generated by the fan of the refrigeration appliance.
In one embodiment of the method, the following is set up: the suction channel is guided along the heat-generating components of the heat cycle of the refrigeration device, and the suction flow flows along or through the heat-generating components.
Further, the method is characterized by: the volume flow of the suction flow is regulated by a controller and a temperature value, which is provided by a temperature sensor arranged in or on the suction channel.
In an advantageous embodiment of the method, the following is provided: the volume flow of the suction flow delivered by the ventilator is less than or equal to the volume flow of the circulation flow delivered by the fan. In this way, the suction flow is mainly applied to the near-ground region in front of the refrigerating device without adversely affecting the circulation flow.

The circulating flow ZS flows through the take-off side 21 and thus through the entire refrigerating compartment 23 from the vertically downward outlet 27 to the vertically upward inlet 26. As indicated by arrows P, the cold from the circulation flow ZS and the refrigerating compartment 23 is discharged from the take-off side into the ambient air due to the temperature gradient and flows outwardly in the direction of the near-ground area 10 in front of the refrigeration device 20.

The following embodiments, although not explicitly shown, are also included: a temperature sensor and a controller for the volume flow control of the ventilator 7 depending on the temperature value, in particular of the suction flow AS. This control can be integrated in the volume flow controller of fan 12 of refrigerating device 20, so that the two volume flows of suction flow AS and of recirculation flow ZS are controlled in a correlated manner. In the illustrated embodiment, the volume flow of the suction flow AS delivered by the ventilator 7 is by default smaller than the volume flow of the circulation flow ZS delivered by the fan 12, so that the suction flow AS does not negatively influence the circulation flow ZS. However, the volumetric flow of the suction flow AS can also be greater than the volumetric flow of the circulating flow ZS, for example when it is recognized that the suction flow AS is significantly cooler and therefore it can be inferred that cooling air accumulates in the near-ground region 10 in front of the refrigerating device 10.
