Definitions
- the present invention is related to the measurement of variables such as transparency, temperature and conductivity of a fluid, such as water used in household appliances such as washing machines, dishwashers, etc., proposing a device that allows controlling said variables through a very advantageous and practical embodiment.
- a device for measuring variables such as turbidity, temperature, and conductivity of a fluid, such as water used in household appliances such as washing machines, dishwashers, etc.
- This device object of the invention consists of a housing closed by a cover, determining a housing where a functional assembly comprising a printed circuit and electronic elements intended to measure application variables are included, all that functional assembly being arranged on a support single piece of insulating material that determines a base provided with hooks for the fastening of the printed circuit and from which there are pins that determine fittings for the fastening of the electronic measuring elements, as well as guides for accommodation of the connection cables of said elements.
- the support of the functional set determines two pins, in which the respective component elements of a turbidity sensor and the corresponding connection cables are incorporated.
- the base of the support also determines conformations that allow to establish the clamping of the printed circuit by means of a clipping hook of the plate thereof, with the possibility of disassembly. In this way the elements of the functional assembly are safely housed in the device, while the arrangement of the cables inside the guides that determine the pins of the support, in turn ensures the fastening and protection of said cables, to properly maintain your connections.
- the support determines three pins, two of them intended for the incorporation of the component elements of a turbidity sensor and the third for incorporating a temperature sensor, a housing of the device structured with three being provided in relation to this support.
- hollow prominences to accommodate in them the respective pins of the support with the elements of the functional assembly that they incorporate, so that the prominences of housing of the turbidity sensor components are of a length, while the prominence of accommodation of the temperature sensor It is shorter than those others.
- two electrodes can also be incorporated to measure the conductivity of the application medium, which electrodes are arranged by going outside through sealed passages, incorporating through the prominences of the housing in which they are housed.
- the turbidity sensor components which prominences are determined in this case with a recess in the end part, in which the corresponding electrode protrudes.
- the cover of the housing of the device determines on its edge some conformations that correspond and complement with other reciprocals that determines the housing, defining between both some exit passages of the external connection cables; while the fastening of the lid is established by means of housing stems that exit through holes in the lid and are riveted by thermo-highlighting on the outside.
- a turbidity sensor device that can be combined with a temperature sensor and / or with a conductivity sensor, the functional assembly being housed in a closed housing that determines two equal hollow prominences in which the sensor elements are included turbidity together with the elements of the conductivity sensor where appropriate, while in the case of the temperature sensor it is included in a third hollow prominence of the housing of different length than the previous ones.
- the placement of the temperature sensor in a separate individual housing prevents the influence of heat dissipation of the turbidity sensor elements and also facilitates assembly.
- said device object of the invention results from particular characteristics that give it its own life and preferential character with respect to the devices currently known for similar applications.
- Figure 1 shows in exploded perspective the set of a turbidity sensor according to the invention.
- Figure 2 shows in an exploded perspective an embodiment of the turbidity sensor together with a temperature sensor.
- Figure 3 is a perspective of the assembly of the previous figure mounted on observation from the top
- Figure 4 is a perspective of the same set of the previous figure in observation from the bottom.
- Figure 5 is a perspective of an embodiment of the turbidity sensor in conjunction with a conductivity sensor.
- Figure 6 is a perspective of the mounting bracket of the turbidity sensor components in the recommended device.
- Figure 7 is a perspective of the closing lid of the device observed from the bottom.
- Figure 8 is an exploded perspective view of the assembly of the support bracket for the components of a turbidity sensor and a temperature sensor, with the respective elements of said sensors in correlative mounting position.
- the object of the invention consists of a device designed to measure variables such as the turbidity, temperature and conductivity, in relation to a fluid such as water used by household appliances such as washing machines, dishwashers, etc., incorporating all the elements for these functions in a single assembly assembly.
- Said device is constituted by a housing (1) of insulating material, preferably transparent, which is closed with a cover (2), determining a housing in which a functional assembly is included comprising a support (3) on which It incorporates a printed circuit (4) and electronic elements to perform the application functions.
- the support (3) has a base (5), from which two pins (6) are formed in solidarity with it, which are configured as guides and determine at the end a socket for the attachment of the respective components (7 and 8) of a turbidity sensor, the base (5) having holes (9) for the passage of the connecting cables (10) to the outside from a strip (11) associated to the base itself (5), while the cables ( 12) of connection of the components (7 and 8) are housed along the guides defined by the pins (6), thus being protected in the arrangement of the assembly in its extension until the connection with the printed circuit (4).
- the base (5) also determines coupling shapes (13), by means of which the printed circuit (4) on said base (5) is clamped, with the possibility of disassembly.
- the support (3) can determine in itself structural assembly a third pin
- the housing (1) of the device determines hollow prominences (15), in which the pins (6 and 6.1) are housed with the respective elements (7, 8 and 14) responsible for carrying out the application functions, in such a way that one of the prominences (15) houses the pin (6) of the support (3) that comprises the component element (7) of the turbidity sensor, in another of the prominences (15) the pin (6) that leads to the component element (8) of the turbidity sensor is housed and in the third prominence (15) the pin (6.1) that carries the sensor element (14) is housed of temperature, this third prominence (15) being shorter than the other two, in the same way as the relationship between the pins (6) and the pin (6.1) of the support (3).
- two electrodes (16) can also be incorporated, which are arranged in turn connected to the printed circuit (4) and going outside through watertight steps to perform a function of measuring the conductivity of the medium of application; said electrodes (16) being provided to be parallel respectively in relation to the pins (6) of the support (3), including inside the corresponding ones hollow prominences (15) housing said pins
- the housing (1) also determines, in an area of its inner contour, corrugated conformations (21), in correspondence with which the cover (2) determines a block (22) of reciprocal conformations in its periphery, defining between the two sets of conformations (21 and 22), when the cover (2) is incorporated in its assembly, passageways for the cables (10) for connection to the outside, which are caught and held between the mentioned conformations (21 and 22) , so that their retention is perfectly ensured.
- the cables (10) can extend freely outside, to be connected where they are of interest, according to figures 1 and 5, or they can end up in a connector (23) associated with the cover (2), according to the figures 2, 3 and 4.
- a connector (23) associated with the cover (2), according to the figures 2, 3 and 4.
- said connector (23) is provided in a lateral arrangement angled at 30 °, which allows ease of connection and disconnection, with possibility of assembly according to any orientation in 360 ° to facilitate the connection without interference with other parts,
