Description

Technical Field

[0001] This utility model relates to a housing for a control device and a control device having a control device and such a housing. Background Technology

[0002] Control devices typically include a control unit (e.g., a humidity regulator or a temperature regulator) and a housing that protects and contains the control unit.

[0003] Control devices (e.g., humidity controllers or temperature controllers) are typically used to adjust a physical quantity (e.g., relative humidity or temperature) to a desired value, whether the physical quantity remains constant or is intentionally changed. The physical quantity can also be called the control quantity, and its desired value can be called the setpoint or reference variable.

[0004] To adjust a setpoint, a rotatable adjusting component, such as a rotary adjuster or knob, is typically used. These adjusting components are connected to a control device so that the desired setpoint can be specified by rotating the component to a corresponding position. To limit the adjustable range of the adjusting component, for example, to prevent the rotational position from falling below a minimum or rising above a maximum value, a mechanical stop can be provided. Control devices with such stops are known, wherein the stops are soldered to a circuit board such that they limit the rotational movement of the adjusting component according to minimum and maximum values.

[0005] The manufacturing and assembly of such control equipment requires a significant amount of labor and time. Utility Model Content

[0006] Therefore, the purpose of this invention is to simplify the manufacturing and assembly of such control equipment.

[0007] According to this invention, this objective is achieved by the housing and control device described below.

[0008] Specifically, according to this invention, this objective is achieved through a housing for a control device, particularly for a humidity regulator or temperature regulator, the housing comprising: a housing bottom; a housing cover, which is connectable to or connected to the housing bottom; and an adjustment device for adjusting parameters of the control device. The adjustment device has at least one adjustment member rotatably arranged within the housing and operable from the outer side of the housing cover to rotate the adjustment member to a rotational position corresponding to the parameters. The housing cover and / or housing bottom has at least one stop formed on the inner side of the housing cover and / or housing bottom, adapted to restrict the rotational movement of the adjustment member in a first end position and a second end position. The housing cover and / or housing bottom are integrally formed.

[0009] Therefore, this utility model is based on the concept of integrally molding the housing cover and / or housing bottom. In other words, the entire housing cover and / or housing bottom (i.e., including all its components, such as stops) is made as a single piece, i.e., from the initial continuous... The material (especially casting material) or workpiece is used. This clearly distinguishes the housing according to this invention from the housing cover and / or housing bottom, which are initially assembled from two or more separate single pieces (especially from the base and separate stops) into a connected component.

[0010] The integral molding of the housing cover and / or housing bottom has various advantages. This reduces the number of components, thus simplifying manufacturing and assembly. Furthermore, it eliminates vulnerable connection points, thereby improving the stability of the housing. In particular, the mechanical stop according to this invention is part of the integral housing cover and / or housing bottom, thus providing even greater stability.

[0011] Preferably, the integral molding of the housing cover and / or housing bottom according to this invention is achieved by means of a molding process, particularly injection molding. Particularly preferably, the stop is produced in an injection molding die for the base of the housing cover and / or housing bottom. Therefore, the stop is preferably manufactured together with the base of the housing cover and / or housing bottom in the same injection molding die. Here, the base of the housing cover may include, for example, a cover plate and circumferential sidewalls, and the base of the housing bottom may include, for example, a base plate and sidewalls.

[0012] The parameter to be adjusted can be any parameter of the control device. Preferably, the parameter is a set value, i.e., a desired value, a control quantity (i.e., a variable), and in particular, a physical quantity that should be adjusted by the control device, whether the physical quantity remains constant or is changed intentionally. For example, the control quantity can be relative humidity or temperature, which can also be any other physical quantity.

[0013] The rotational position of the adjusting component corresponds to the specific value of the parameter to be adjusted. Preferably, the first end position forms the minimum value of the parameter to be adjusted, while the second end position forms the maximum value of the parameter to be adjusted. Therefore, the adjustable range preferably extends from the first end position to the second end position. Here, the stop member according to this invention ensures that the adjusting component can only rotate or be adjusted to a rotational position corresponding to the first end position or the second end position, or a position in between.

[0014] The adjusting component can be operated from the outer side of the housing cover in various ways. Therefore, the adjusting component can be operated manually or automatically. Manual operation is preferred (e.g., by hand or tool) and can be achieved either directly (i.e., through direct contact with the adjusting component) or indirectly (e.g., by operating another component and transmitting rotational motion to the adjusting component). Other types of operation are also possible.

[0015] The housing according to this invention is designed to house a control device, particularly a humidity regulator or temperature regulator. Specifically, the housing is designed for a mechanical humidity regulator used to regulate relative air humidity via a heater and a fan. The housing can also be used for other control devices and other equipment.

[0016] Preferred embodiments of the present invention are given in the dependent claims.

[0017] In a preferred embodiment of this invention, the stop member has a stop rib for adjusting the component at both the first and second end positions. Thus, the area between the stop ribs can be at least partially and substantially free of material, thereby advantageously saving material.

[0018] Particularly preferably, each stop rib has a stop surface adapted to cooperate with the adjusting component in a form-fitting manner at its respective end position. Therefore, each stop surface has a geometry that matches the geometry of the corresponding area formed by the adjusting component for stopping purposes. These mutually fitted surfaces enable the distributed transmission of force upon impact to a larger surface area. This improves the load-bearing capacity of the stop. Furthermore, damage caused by localized force peaks is reduced.

[0019] Furthermore, advantageously, the stop member has support ribs that connect the stop ribs to each other to provide support in both stopping directions. Therefore, the support ribs are preferably arranged to absorb at least a portion of the stopping force acting on one stop rib and transfer that force to the corresponding other stop rib. This stabilizes the stop ribs, thereby further increasing the load-bearing capacity of the stop member and further reducing the risk of damage.

[0020] Preferably, the stop, particularly the stop rib, is connected to the sidewall of the housing cover and / or the housing bottom to provide support in at least one stopping direction. Therefore, in this preferred embodiment, the housing cover and / or the housing bottom has a sidewall that protrudes, for example, from the cover plate of the housing cover and / or the base plate of the housing bottom and is formed in a circumferential shape. This sidewall is connected to the stop such that it supports the stop in at least one stopping direction, preferably in two stopping directions, to further increase the load-bearing capacity of the stop and further reduce the risk of damage.

[0021] Within the scope of this utility model, a control device having a control device and the aforementioned housing is also provided, wherein the control device is arranged in the housing.

[0022] For details regarding the effects and advantages of the control device according to this invention, please refer to the description related to the housing. Therefore, the housing can be disclosed and claimed either as part of the control device or as the housing itself (i.e., independently of the control device). Attached Figure Description

[0023] The present invention will now be described in more detail based on embodiments and with reference to the accompanying schematic diagrams. In the drawings:

[0024] Figure 1 A front view of the housing according to an embodiment of the present invention is shown;

[0025] Figure 2 It shows Figure 1 Side view of the shell;

[0026] Figure 3 It shows Figure 1 A cross-sectional view of the housing, wherein the adjusting component is in the first end position; and

[0027] Figure 4 It shows Figure 1 A cross-sectional view of the housing, with the adjusting component in the second end position. Detailed Implementation

[0028] Figure 1 A housing 1 for a regulating device according to an embodiment of the present invention is shown, specifically a housing 1 for a mechanical humidity regulator. The housing 1 includes a housing cover 10 and a housing bottom 20 (see [reference]). Figure 2 ) and adjusting device 30. In Figure 1 The outer side 11 of the housing cover 10 is shown.

[0029] The regulating device 30 is used to adjust the parameters of the control device, specifically the desired relative humidity, which the control device uses as the setpoint for regulating the actual relative humidity. The regulating device 30 can also be used for other purposes, such as adjusting other parameters (e.g., temperature setpoint) or selecting different operating modes.

[0030] The adjusting device 30 has an adjusting member 31, specifically an adjusting wheel or a rotary adjuster. The adjusting member 31 is rotatably arranged in the housing 1. For example, the adjusting member 31 may be rotatably fastened or mounted on a circuit board of the adjusting device arranged in the housing 1, or rotatably fastened or mounted on a housing component (e.g., housing cover 10 or housing bottom 20). The adjusting member 31 may also be arranged in the housing 1 in other ways.

[0031] Adjustment member 31 is arranged in housing 1 such that it can be operated from the outer side 11 of housing cover 10. Therefore, adjustment member can be accessed from the outer side 11. Specifically, an opening is formed in the cover plate 17 of housing cover 10, through which adjustment member 31 can be operated (i.e., rotated) from the outer side 11. Adjustment member 31 may, but does not necessarily, extend from housing cover 10 (specifically cover plate 17).

[0032] In the illustrated embodiment, the adjustment component 31 can be operated using a tool (specifically, a screwdriver). The adjustment component 31 can also be operated manually.

[0033] With proper operation, the adjusting component 31 can be rotated to a position corresponding to the parameter. Therefore, the rotational position of the adjusting component 31 corresponds to the specific value of the parameter to be adjusted.

[0034] Adjustment component 31 can be in the first end position (at Figure 1 The adjustment is between the first end position (shown in the diagram) and the second end position. In the illustrated embodiment, the first end position corresponds to a minimum value, specifically slightly less than 30% relative humidity (rF), and the second end position corresponds to a maximum value, specifically slightly greater than 95% relative humidity (rF). In this way, the end positions define the adjustable range of the parameter.

[0035] The adjusting member 31 can be rotated or adjusted to any rotational position between the first end position and the second end position. Therefore, the adjustment of the adjusting member 31 is stepless or continuous. It is also conceivable that the adjusting member 31 can only be adjusted to predetermined discontinuous rotational positions.

[0036] To prevent the adjusting member 31 from rotating to a position outside the adjustable range, the housing cover 10 has a stop 12 for the adjusting member 31 at the first end position and the second end position (see...). Figure 3 and Figure 4 The stop 12 is formed on the inner side of the housing cover 10 and is adapted to limit the rotational movement of the adjusting member 31 at the first end position and the second end position.

[0037] The housing cover 10 is integrally molded, specifically by means of an injection molding process. In other words, the entire housing cover 10 (i.e., including all components of the housing cover 10, such as the stop 12) is made of a single piece, i.e., from an initially coherent material (specifically, a casting material). Here, at least the stop 12 is produced together in an injection molding mold of the base of the housing cover 10, wherein the base has at least a cover plate 17 and preferably circumferential sidewalls 16.

[0038] Figure 2 It shows Figure 1Side view of housing 1. The bottom 20 of the housing is connected to the housing cover 10.

[0039] The bottom of the housing 20 has a substantially flat base plate 24 and circumferential sidewalls 23 arranged substantially vertically on the base plate 24. The base plate 24 and the sidewalls 23 form the base of the bottom of the housing 20. A connecting device 22 for connecting the housing 1 to the surrounding environment is provided on the outer surface of the bottom of the housing 20, specifically on the outer surface of the base plate 24.

[0040] The circumferential sidewalls 16 of the housing cover 10 are arranged substantially vertically on the cover plate 17. The cover plate 17 is constructed in a stepped shape, including a first region for an opening for operating the adjustment component 31. Figure 2 The lower part of the middle) and the second part ( Figure 2 The upper region of the shell is further away from the bottom 20 of the shell.

[0041] Ventilation openings, specifically ventilation slots, are formed in the side walls 16 and 23 of the housing cover 10 and the housing bottom 20. The ventilation openings extend from the side wall 16 of the housing cover 10 to the side wall 23 of the housing bottom 20.

[0042] Figure 3 and Figure 4 They are shown respectively Figure 1 and Figure 2 A cross-sectional view of the shell 1, wherein the section is along the... Figure 2 Section AA is marked as selected. Figure 3 and Figure 4 The only difference is the rotational position of the adjustment component 31 shown. Figure 3 The adjustment component 31 is shown in the first end position corresponding to the minimum value, while Figure 4 The adjustment component 31 is shown in the second end position corresponding to the maximum value.

[0043] exist Figure 3 and Figure 4 The stop 12 can be seen in the cut. It can be clearly seen from the shaded part of the cut-out housing cover 10 that the stop 12 and the base of the housing cover 10 are integrally formed as part of the housing cover 10, that is, formed from a single piece.

[0044] The stop member 12 has a stop rib 13 for the adjusting member 31 at both a first end position and a second end position. Each stop rib 13 has a stop surface 14 adapted to cooperate with the adjusting member 31 in a form-fitting manner at the respective end position. Therefore, each stop surface 14 has a geometry that matches the geometry of a corresponding region of the adjusting member 31 formed for stopping purposes (specifically, the side wings of the protrusion 32 of the adjusting member 31). The stop surfaces 14 (specifically, the stop ribs 13) and the side wings of the protrusion 32 extend substantially in the radial direction of the rotation axis of the adjusting member 31.

[0045] The stop member 12 has support ribs 15 that connect the stop ribs 13 to each other to provide support in two stopping directions. The stopping direction should be understood as the direction of movement of the corresponding area (i.e., the corresponding flank) formed by the adjusting member 31 for stopping purposes shortly before impacting the stop member. The support ribs 15 extend between the stop ribs 13 substantially tangentially to the direction of rotation of the adjusting member 31. Thus, when the stop is in the first end position and in the second end position, the support ribs 15 can support the substantially radially arranged stop ribs 13, i.e., absorb at least a portion of the stopping force exerted on the stop ribs 13 by the adjusting member 31.

[0046] The stop rib 13 is connected to the side wall 16 of the housing cover 10 to provide support in both stopping directions. Therefore, the stop rib 13 extends substantially in the radial direction of the rotation axis of the adjusting member 31 to the circumferential side wall 16.

[0047] In this regard, from Figure 3 and Figure 4 In the shaded portion of the cross-section of the housing cover 10, it can be seen particularly clearly that the stop 12 and the sidewall 16 of the housing cover 10 form a continuous structure without any connection points, connecting lines, etc. More precisely, the components of the housing cover 10, namely, the stop 12, the cover plate 17, and the sidewall 16, are integrally formed, i.e., made from the originally continuous structure (i.e., the casting material).

[0048] exist Figures 1 to 4 In the embodiment shown above, the stop 12 is formed as part of the housing cover 10. Alternatively or additionally, the stop 12 may also be formed as part of the housing bottom 20. This stop 12 has the same characteristics as described above. Figures 1 to 4 The embodiments shown have essentially the same structural and functional features.
