Abstract

The present invention relates to a housing (10) for a control device with a first area (11) and a second area (12) projecting beyond the first area (11), the second area (12) forming a receiving space for an electrical component. To enable intuitive operation of the control device, particularly in limited visibility conditions, and to simultaneously save material, it is proposed that the second area (12) have a substantially polygonal, in particular rectangular, shape, wherein a first corner (13) and a second corner (14) of the second area (12) each have a radius that differs from the radius of the other corners, and wherein the radius of the first corner (13) is larger than the radius of the second corner (14).

Description

The invention relates to a housing for a control device having the features according to the preamble of claim 1. Such a housing is, for example, made of US D1,002,397 S known. Control devices serve to compare certain setpoint values with certain actual values and, if necessary, to initiate action to bring the actual value into line with the setpoint. Thermostats and humidistats are examples of this. These devices continuously or discretely measure or receive actual temperature values, or alternatively, humidity values, within a specific area, such as a room in a building. These values are compared with a preset setpoint, which can be provided by a control device. Thermostats and humidistats are also common and widely used, allowing the setpoint temperature or humidity to be manually adjusted. If the actual value is found to be lower than the setpoint, the thermostat activates a heating system to raise the room temperature. In the case of a humidistat, the switching function depends on excessively high humidity, at which point it activates a heater. The same principle can also be used to regulate cooling. Likewise, control devices are known that regulate humidity in a room according to the same principle. An example of a thermostat with manual setting of the target temperature is from the US D1,002,397 S is known. This includes a rotary control and a scale arranged around the rotary control. To change the target temperature, a user simply needs to rotate the rotary control to the corresponding position. Such a control device is relatively wide and therefore requires a considerable amount of space on the DIN rail. These designs result in less space on the DIN rail, which incurs additional secondary costs for the control cabinet manufacturer. Furthermore, the control device is largely point-symmetrical around the rotary knob. This makes it difficult for a user to operate the control device intuitively, i.e., to precisely adjust the rotary knob, under limited visibility conditions, such as dim or no lighting. The present invention therefore aims to describe a control device which, compared to the prior art, enables intuitive operation even under limited visibility conditions. A further aspect concerns material savings and the associated reduction in weight and costs, as well as lower resource consumption, which ultimately also results in lower CO2 emissions. This problem is solved by a housing for a control device with the features according to claim 1. Advantageous further developments are the subject of the dependent claims. The housing according to the invention for a control device has a first area and a second area. The second area projects beyond the first area and forms a receiving space for an electronic component. This can be, for example, a temperature sensor or a humidity sensor, or another electronic component such as a processing unit or a control unit necessary for the operation of the control device. Also included and claimed is a design in which the receiving space is formed by the first area and the second area. In this case, the receiving space is located at least partially in the space between the first area and the second area. Such a design allows for space-saving and thus material-saving accommodation of the electronic component while simultaneously providing an aesthetically pleasing finish. According to the invention, the second area has a substantially polygonal, i.e., multi-sided, shape. In particular, the second area has a substantially rectangular shape. Its corners are not necessarily formed by two edges meeting at strict right angles, but rather it is understood that the opposite edges are arranged parallel to each other. Such a design is easy to implement from a manufacturing perspective. The housing according to the invention for a control device is further characterized in that a first corner and a second corner of the second region each have a radius that differs from the radius of the other corners. For example, the second region can have two corners where the respective edges meet at strictly right angles, so that, apart from manufacturing-related deviations, there is no rounding in the corners. The first corner and the second corner, on the other hand, have a clearly recognizable and also desirable radius from a manufacturing perspective. The radii enable a material-saving design of the housing of the control device, thus optimizing its weight and therefore also its cost. The radius of the first corner is larger than the radius of the two ten corner. In limited visibility conditions, this allows a user to intuitively determine by touch where the individual components of the control device are located, and consequently to operate them safely and reliably. The second area and its design are not only based on technical aspects, but also offer creative freedom for aesthetic design. According to a preferred embodiment, the first and second corners are arranged diagonally opposit
