Description

The present invention relates to a cleaning device for cleaning radiators and heat-transferring surfaces, in particular panel radiators, according to the preamble of claim 1. Panel radiators consist of several heating plates made of steel or other materials through which a heating medium flows. Between the heating plates, several metal sheets, known as convection fins, can be installed. These fins absorb heat from the heating plates and warm the air flowing through the radiator via convection, thus significantly increasing the proportion of heat emitted by convection. Often, the heating plates and convection fins form a finned structure, which increases the surface area. Due to the large surface area of the heating plates and convection fins, panel radiators emit the majority of their heat in the form of convection. Panel radiators with convection fins can be operated with particularly low flow temperatures due to the significantly increased surface area. At the same time, the temperature difference between the flow and return temperatures can be kept especially high, ensuring economical operation for the heat generator regardless of the fuel used, such as natural gas, heating oil, or electricity. Dirt and dust particles that accumulate on the heating plates and convection plates over time reduce the heat output of the panel radiators to the ambient air, which significantly reduces the efficiency of the panel radiators, necessitates increased fuel consumption, and consequently increases CO2 emissions. Besides the deterioration of the indoor climate due to reduced heat output, such soiling poses a significant health risk for people with dust allergies, especially at the beginning of the heating season when air circulation stirs up dirt and dust particles. These dirt and dust particles also settle on furniture, creating an additional burden in the form of dust deposits. The DE 10 2020 105 740 A1 Disclosure reveals a device for cleaning a radiator, comprising an upper frame and a lower frame, each completely covering the radiator's horizontal end faces. A cleaning fluid is introduced into the radiator via the upper frame, collected by the lower frame, and extracted. To prevent leakage, the upper and lower frames must be fitted as tightly as possible onto the radiator. A casing element surrounding the radiator's sides and positioned between the upper and lower frames prevents lateral leakage. Due to the water requirement, the device is heavy and has a complex design. Furthermore, the cleaning process, requiring the attachment of the casing element, is particularly time-consuming and can lead to moisture damage, for example, if water leaks onto a wooden floor. From the DE 201 09 287 U1 A device for cleaning radiators is known. The device comprises a blower and suction unit connected via a flexible tube to an air nozzle and a suction nozzle. The air nozzle is placed on top of the radiator and the suction nozzle on bottom of the radiator in such a way that the air nozzle and the suction nozzle completely cover the radiator in the width direction and partially cover it in the length direction. Since the air nozzle and the suction nozzle only cover a portion of the radiator, sealing tabs are inserted through the radiator in front of and behind the air and suction nozzles to create an airtight connection between them. In this way, a completely closed airflow can be achieved for cleaning the radiator. Following cleaning with the airflow, steam treatment is carried out. For complete cleaning of the radiator, the sealing tabs must be removed from the radiator after the partial cleaning, the air and suction nozzles repositioned, and the sealing tabs inserted through the radiator again. These steps are repeated until the radiator has been cleaned along its entire length. Cleaning radiators with known cleaning devices is particularly complicated and very time-consuming. If the radiator is located under a windowsill or in radiator recesses, cleaning using this method is either impossible or extremely difficult. The present invention aims to provide a cleaning device for radiators that enables quick and particularly easy cleaning. The above problem is solved by a cleaning device according to claim 1. Advantageous embodiments are the subject of the dependent claims. The proposed cleaning device is designed for cleaning a radiator, including one with convection fins. The cleaning device includes a compressor unit for generating an airflow by means of overpressure, with an air nozzle unit connected to the compressor unit for directing the compressed air into the radiator. The air nozzle unit is either mounted on or positioned at a distance from the upper flat surface of the radiator. The air nozzle unit only partially covers the upper flat surface in the longitudinal and/or transverse direction. The cleaning device further comprises a suction device for extracting air and/or air containing contaminants, such as dust particles,
