Description

WIRELESS TEMPERATURE VERIFICATION SYSTEM FIELD OF THE INVENTION The present invention refers to a wireless temperature verification system useful to reduce the risk of burn of a user. The system includes a temperature sensor / transmitter on the end of a tap, which communicates through a wireless link to a controller. The wireless link is used to facilitate installation on a tap. The invention also provides a digital display with audio and / or visual alarms to indicate whether a pre-set maximum temperature and a shut-off valve have been exceeded to interrupt the flow of water to the faucet.

BACKGROUND OF THE INVENTION The risk of burn through the one of hot water faucets by certain groups of people, particularly incapacitated, elderly or very young children, is present in homes and institutions. In general, these people confuse hot water and cold water in a tap or have difficulty operating a tap, which leads to dangerous exposure to hot water from the tap. Typically, water temperatures in excess of 42 ° C can cause damage to unprotected skin. While, in several hot water heaters, it is possible to set the thermostat at a lower temperature, many hot water tanks have their thermostats set at an excess of 60 ° C in order to ensure an adequate supply of hot water to the system to tasks such as washing or operating a dishwasher, where a higher water temperature is desired. Accordingly, there has been a need for products that effectively control the flow of hot water from a tap to ensure that potentially hot temperatures do not exceed through particular faucets in a hot water system. The above temperature monitoring and temperature closure systems exist to control the flow of water or a fluid through conduits. There are also systems with respect to faucets that regulate and control the flow of water from a tap. These systems usually include mechanisms to electronically check the water temperature and adjust the flow of hot and cold water to control a selected temperature. A disadvantage of these systems is that they are usually highly complex, requiring a complete replacement of the entire faucet to implement their installation. The complexity generally leads to an increased cost for the consumer. In addition, these prior systems can detract from the aesthetic appearance of a particular faucet by requiring unpleasant looking joints in the faucet or, alternatively, requiring the complete replacement of the faucet with a design that does not complement the overall style or appearance of a bathroom or kitchen. For example, in those systems that do not require the replacement of the existing faucet, the installation detracts from the aesthetic appearance of the faucet either through visible cables or valves and / or complex control panels. Consequently, there has been a need for a device against burns, which can be installed in existing faucets without detracting from the aesthetic appearance of the faucet, specifically without the use of cables or unpleasant-looking mechanisms. In addition, there has been a need for a device against burns, which can be easily installed in a few minutes by either a plumber or anyone who has a minimal experience in plumbing. Specifically, there has been a need for a device that verifies the temperature of the water flowing from a tap and communicates the temperature information to a controller for processing via a wireless communication link. The information received from the controller can be used to provide a digital temperature display or to control a shut-off valve in the event that the water temperature exceeds that of the pre-established value. A review of the prior art indicates that there are systems that provide verification of water temperature, control and closure in the case of excess temperatures. These include devices described in the U.S.A. patent. 4,256,258, patent of E. U.A. 5, 184, 642, patent of E. U.A. 4,756,030, patent of E. U.A. 4,886,207 and patent of E. U.A. 5,226,629. However, none of these patents describe a device, which addresses and resolves the above problems, specifically providing a device, which can be easily updated to existing faucets without significantly detracting from the appearance of the faucet.

COMPENDIUM OF THE INVENTION In view of the above needs, the invention seeks to provide a device against burns, which can be easily configured to existing faucets and which does not significantly detract from the aesthetic appearance of the faucet. Accordingly, the invention provides a temperature sensing device and a transmitter, preferably for attaching to the end of a tap with an eyebolt having a standard thread. The temperature information from the tap is transmitted to the controller, where it can be used to operate a hot water shut-off valve, to provide a digital display of the actual temperature, or both. In the case of a hot water shut-off valve, it is preferable that the shut-off valve be operated through a battery. In one embodiment, the controller and the shut-off valve are different units, which communicate through a wireless link. In another embodiment, the system can provide a reset switch, to allow the user to reactivate his hot water minister if the system has been closed. The system can also be provided with the ability to cancel the system against burns to allow higher temperatures to be obtained. The override aspect may require special keystroke to activate specific tasks such as washing clothes or frets. Thus, according to the invention, a tap control system is provided to verify the temperature of a fluid flowing from a tap, the tap control system comprises: a temperature sensor and transmitter for joining the tap, the sensor and temperature transmitter to obtain temperature data of a fluid flowing from the tap and to transmit the temperature data; a controller for receiving and processing the temperature data, wherein the controller includes means for interrupting the flow of fluid from the tap, if the temperature of the fluid flowing from the tap exceeds a preset value. The invention also provides a tap control system comprising: a temperature sensor and transmitter for attaching to a tap, the sensor and temperature transmitter to obtain temperature data of a fluid flowing from the tap and to transmit the data of temperature; a controller for receiving and processing the temperature data, wherein the controlled r includes means for displaying the temperature of the fluid flowing from the tap. In a preferred embodiment, the temperature sensor and transmitter continuously transmits the temperature data and includes means for transmitting a pass signal. Preferably, a pulse width modulated signal is used. The valve unit preferably includes means for connecting between an ignition safety and shutdown safety mode, wherein the valve unit is connected to the shutdown safety mode upon receipt of a pass-through signal. Preferably first and second time circuits are used during the power-on and safety-off modes. Furthermore, it is still preferred that the valve unit includes means for verifying the state of the battery and alarm means for notifying the user in the event of a low battery state. In this embodiment of the invention, the unit may also include a base unit for receiving, displaying and interpreting the temperature data of the sensor and temperature transmitter, which itself may include alarm means to notify the user if the temperature The fluid that flows from the tap exceeds a pre-set maximum temperature.

DETAILED DESCRIPTION OF THE INVENTION In FIGS. 1 a, 1 b and 1 c, three different embodiments of a wireless temperature verification device 10 are shown. With reference to FIGS. 1 a, 1 b and 1 c, a tap 12 mounted on a manifold 14, the manifold is shown in cut-off form. In each case, the temperature verification device 10 shown comprises separate components, namely, a temperature sensor / transmitter 16, a controller 18 and a shut-off valve 20, configured to the hot water supply 21 of the tap 12. In the embodiment shown in Figure 1 a, the controller 18 and the shut-off valve 20 are shown as being connected through a cable link 22. The controller 18 is shown as having a digital display. Figure 1 b shows a modality with a wireless link between the controller 18 and the shut-off valve 20 with the controller 18 also having a digital display. Figure 1 c shows a mode with the controller 18 and the shut-off valve combined in a single unit without a digital display. A reset button 24 on the temperature sensor / transmitter 16 is also shown. Referring to Figure 2, the temperature sensor / transmitter 16 is a compact unit having a circuit, which verifies the temperature of the water flowing from the tap 12 and which transmits the temperature information to the controller 18. The circuit sensor / transmitter 26 includes a sensor 26, a battery 27 and the transmitter 28 within a sensor / transmitter body 30. The sensor / transmitter body 30 is preferably a compact body having a hole 32 to allow the passage of water to through it. The body 30 is also preferably equipped with normal tap threads to allow the connection of the body 30 to the tap 12 thus allowing water to flow through the hole 32 on the sensor 26. The temperature sensor / transmitter 16 can also be provided with a reset button 24 for reactivating the water flow, if the associated shut-off valve 20 has been activated and / or an LED 24a which serves as a visual alarm. In Figure 3 there is shown a flow diagram of the operation of the temperature sensor / transmitter 16. By not using the tap 12, the tap circuit is in a standby mode (box 40), wherein a signal of transmission of Temperature is not generated and transmitted in order to conserve battery power. Since in the idle mode 40, a temperature reading (box 42) is periodically taken from the sensor 26. The battery level is checked (box 43), and if correct, the temperature change scale (box 44) it is determined based on a temperature reading taken approximately 1 second previously. If the temperature change scale (box 44) is smaller than a pre-set value, for example 2 ° C per second, the circuit is said to be in the standby mode (box 40). If the temperature change scale (box 44) is greater than 2 ° C per second, the transmitter 28 is turned on. The transmitter 28 will remain active for a pre-set time value, for example, 120 seconds, after which time, the transmitter will be closed (box 46). When the transmitter is ON, the temperature data (box 48) are read and transmitted to the controller 18. At the end of the preset time value (box 50), the circuit will read 3 temperatures for a period of 15 seconds (box 52) and store these readings. The circuit will determine if the three temperature readings are equal (box 54) and, if so, the transmitter 28 is turned off and the unit returns to the standby mode (box 40). If the three temperature readings are not equal in the box 54, the time controller is restored to the preset value and the transmitter 29 remains ON and continues transmitting the temperature data (box 48). During both the ENCEN DI DO and the OFF mode of the transmitter, the circuit also continues to check the status of the battery 27. If the battery status is not correct, a low battery signal (box 60) is transmitted to the controller 1 8. The low battery signal is transmitted at a different frequency or pulse width. In an embodiment of the invention having a reset button on the body 30, the circuit can determine if the water temperature is greater than a set value (box 62), for example 42 ° C. If the water temperature exceeds this value, the temperature data continues to be transmitted and an LED 24a can be activated to turn on (box 64). The compression of the reset button (box 66) will cause a restored signal (box 68), at a different frequency or pulse width, to be transmitted to the controller 18 and turn off the LED (box 70), if any. Referring to Figures 4a and 4b, the controller 1 8 includes a circuit, which receives and interprets the signals from the temperature sensor / transmitter 16. In a preferred embodiment, the controller 1 8 includes a LC D 80 screen, push buttons 82 and LED indicator 84. Internally, controller 1 8 includes a power supply 86 and a controller circuit 88, as shown in Figure 4b. Figure 5 shows a flow chart of the operation of the controller circuit. The controller circuit 88 includes a sleep mode, a safe OFF mode and a safe ON mode. The controller circuit 88 contemplates the use of 5 operating frequencies and five signaling variables. However, it is understood that the operation of the controller described herein is merely representative of several control schemes, which may be implemented. Referring to Figure 5, during the standby mode (box 100), the variables designated "a", "b", "c", "v" and "s" are set to zero. The battery status of both the controller and the tap circuits is verified, the controller battery 86 through a battery check circuit and the tap circuit battery upon receipt of a battery voltage signal (frequency designated 5). ) from the temperature sensor / transmitter 16. If the battery voltage of any circuit is insufficient, a low battery indicator, such as LED 84, will be activated (box 104) indicating that the replacement of one or more batteries is required . Alternatively, an LCD segment on the controller's display may be illuminated, indicating the low battery status. If the variable "s" remains false (box 106), ie zero, a valve shut-off signal (box 108) is sent to the shut-off valve 20 at a different frequency (frequency designated 2). If "s" is true, that is, one, the battery voltage check is repeated (box 102). If the battery voltage (box 102) is correct, the circuit 88 determines whether it is receiving a temperature transmission signal (box 110). If it is NO, the circuit is set to idle mode (box 100). If it is Sl, indicating the use of the tap, the circuit 88 fails with the safety ON mode and sets the variables "a" and "v" as true. The variable "a" activates the LCD screen 80. The variable "v" activates the shut-off valve 20 allowing the water to flow (box 114). The circuit 88 will then determine if the temperature transmission is still received (box 116). It is, is not it, then "v" is set as false and closing valve 20 is closed (box 118). If the temperature transmission is still received (box 116), the circuit 88 continues to receive and display the temperature transmission (box 120) and check whether the variable "b" is true (box 122). If "b" is true, and T2 is zero (box 124) (T2 is described below), the unit is kept in safety ON mode and "b" is set to false (box 126). If "b" is false (box 122), circuit 88 checks whether the security aspect is ON (box 124a). If it is NO, T2 is given a pre-set value, for example, that corresponds to an ON time of 120 seconds, and "b" is set to true (box 126a), thus bringing the system to a passing condition, where the temperature of the tap water is allowed to exceed its maximum closing temperature. The security aspect (box 124a) can be deactivated through a specific key sequence in controller 18. If the security aspect (box 124a) is ON, circuit 88 determines whether the water temperature exceeds the maximum closing (box 128). If it is Sl, the alarm is ON, thus activating LED 84 and / or a vibrating alarm and "v" is set to false, thus causing valve 20 to close (box 130). For a wireless model, this is achieved through a different radio frequency (frequency designated 2). If the reset button is pressed, or the frequency 4 is received, (box 132), a temperature reading is taken and the temperature is displayed (box 134). If the reset button is not pressed, or the frequency 4 is not received, the alarm remains ON (box 130). In box 136, the temperature reading is compared to the maximum closing temperature. If the temperature is higher than the closing temperature, the temperature readings are read and presented (box 134). If the temperature is lower than the closing temperature, the alarm goes OFF (box 138). After the alarm has been turned OFF, 2V2 is set as true, the shut-off valve 20 is turned on through frequency 3 (wireless model) (box 140). With the valve 20 ON, the battery level is checked in the controller and the tap (box 142). If the battery levels are correct, the system checks the temperature readings (box 1 16). If the battery levels in the controller 88 or the sensor / temperature transmitters are not correct (box 142), "s" is set to false and a low battery indicator is activated (box 104).

The shut-off valve 20 is a valve configured for hot water supply 21 of a faucet 12 and responds to the controller 18. The shut-off valve 20 includes a shut-off valve circuit 146, the battery 148 and the pressure sensor 149, shown schematically in Figure 6. Figure 7 shows a flow diagram of the valve actuator. With the tap turned on, the valve actuator is in a standby mode with the valve open (box 150). During standby, the valve actuator circuit checks the condition of the battery 148 (box 152). If the state of the battery is low, the valve 20 is turned off (box 154). If the battery status is correct, the valve circuit expects to receive the closing signals from the controller 18. These can be received as three different frequencies, designated as frequency 1 to place the valve in a standby mode (box 156), frequency 5 indicating a low battery condition (box 158) of controller 18 or frequency 2 indicating that the maximum preset temperature has. been, exceeded (box 160). In the case of receiving a signal of rest of frequency 1 (box 156), the closing circuit 146 will turn off the valve (162) and will remain off until an activation signal is received through a pressure perception signal (box 164). A pressure sensor 149 is mounted downstream of the valve 20 to the tap usage signal. Accordingly, if the tap is turned off, the pressure sensor 149 will detect a line pressure between the shut-off valve and the tap valve. If the tap is turned on, the line pressure will drop, thus producing a signal to turn the shut-off valve (box 168) ON. The valve will remain ON in a sleep mode (150). If no pressure signal is received, the system will wait with the valve OFF (box 166). Box 164 represents the start site of the program during activation or battery change. In the case of receiving a frequency signal 5 or a frequency signal 2 indicating a low battery state in the spigot controller or battery or a water temperature in excess of the maximum temperature, the valve 20 is turned off (box 154) . If a frequency signal 3 is received (box 170), the valve 20 is turned on (box 174), otherwise the circuit waits for the appropriate valve signal ENCEN DI DA (box 172). It is understood that various forms of presentation and / or programming of the system control can be implemented without departing from the spirit and scope of the invention. Figure 8 shows a typical schematic diagram of a controller 18. The programming sequences can enable the user to set the maximum closing temperature, connected between presentations in Fahrenheit and Celsius, connected between ENCEN DI DO modes of safety and OFF safety and provide the appropriate audio and visual alarms if a dangerous water temperature occurs. The presentation can also show the battery status of the controller 18 and the temperature sensor / transmitter 16.

The operation of a further and preferred embodiment of the invention is shown in Figures 9-12, which describe control schemes of the temperature sensor / transmitter 16, a display unit 18 and a shut-off valve 20. With reference to the Figure 9, the temperature sensor / transmitter 16 is shown to communicate via an RF link directly with both the base unit 18 and the shut-off valve 20. In this embodiment, the temperature sensor / transmitter 16 continuously transmits the temperature to both the base unit 18 and the shut-off valve 20. Figures 10-12 show control schemes for the temperature sensor / transmitter 16, the base unit 18 and the shut-off valve 20, respectively. Referring to Figure 10, the temperature sensor / transmitter 16 continuously transmits temperature data as shown in the case 200. If the step button 24 is pressed (box 202) a specific step signal (204) is transmitted. The temperature sensor / transmitter 16 contemplates the use of a pulse width modulated signal, wherein the pulse width of the signal is proportional to a specific temperature. Compression of the pass button will cause a specific signal of a particular pulse width to be transmitted, which is interpreted as a pass-through signal from the valve unit 20. Referring to Figure 11, the base unit receives and processes temperature data from the temperature sensor / transmitter and presents this information. When activated (box 210), the variables "B" and "T" are manually set as B = 1 and T = 1 through a key switch located on the base unit. The variable "B" indicates two modes of operation, mainly security on and security off. If B = 1, the base unit is in safety mode, while if B = 0, the base unit is in safety shutdown mode. The variable "T" indicates the temperature scale. T = 1 will present the temperature in degrees centigrade, while T = 0 will present the temperature in degrees Fahrenheit. After activating, box 212, the base unit determines whether it is receiving the temperature data. If not, the circuit returns to the activation module (box 210). If the unit is receiving the temperature data, the circuit determines the operating mode. If B = 0 (box 214), the temperature data are interpreted and presented (box 216). If the temperature exceeds a preset security value (box 218), a vibrator will turn on and the LCD screen may turn on (box 220) and continue to check the reception temperature data (box 222). If the temperature is lower than a pre-set value (box 218), the unit will similarly continue to check the reception of the temperature data (box 222). If the unit has been set in the safety shutdown mode (box 214) and B = 0, the temperature data is interpreted and displayed (box 224). However, in the safety shutdown mode, no alarm is activated if a signal corresponding to high temperature water is received. As in the safety ignition mode, the unit continues the verification of the reception of the temperature data (box 222). If, in box 222, the temperature data is not received, the activation circuit is activated (box 210). With reference to Figure 12, the operation of the valve unit is described. Generally, the valve unit receives and interprets temperature and pass-through data from the temperature sensor / transmitter. The valve unit has three variables, particularly the safety mode., "S", valve, "V", and vibrator, "B", each of which can be either 1 or 0. S = 0 corresponds to a security shutdown mode, while S = 1 indicates a security on mode. V = 0 sets the valve closed, while the open valve and B = 0 indicates that the alarm is off, while B = 1 indicates that the alarm is off. The circuit also includes time control variables T and T2, which represent specific time control values in seconds. In the activation (box 230), the variables are set as S = 1, V = 0 and B = 0. In box 232, the unit determines whether it is receiving temperature data or a pass signal. If not, the circuit returns to box 230 and continues the link until the data is received. If the temperature data is received, V = 1 and the valve is open allowing water to flow through the tap. In box 236, a check of the battery is made. If the battery level is correct, the unit continues to determine if the temperature data is being received (box 240), otherwise V is set to = and the vibrator will periodically sound (box 238). In box 240, if the temperature data are being received (ie not a passing signal), S = 1 (box 242) and the temperature data are interpreted (box 244). If the temperature is higher than the closing temperature (box 240). V is set to 0 (valve closed), B is set to 1 (alarm on) and T2 starts counting down (box 248). Typically, T2 could be 5 seconds. Therefore, when T2 is 0, ie 5 seconds have elapsed, (box 250), V is set to 1 (open valve) and B is set to 0 (alarm off). The unit continues to check if it is receiving data (box 252), and, if so, it returns to box 242. In box 246, if the temperature is lower than the closing temperature, the unit checks the battery status ( box 242). If the state of the battery is correct, the circuit returns to box 240, otherwise V is set to 0 (valve closed) and the alarm sounds periodically (box 256). In box 242, if a pass signal is received, S is set to 0 (security shutdown mode) and the time control sequence T begins to count down (box 258). Typically, T could be 5 minutes. When the 5 minutes have elapsed (box 260), S is set to 1 (security on mode) and the circuit proceeds to box 252. In box 240 and box 252, if the unit is not receiving temperature data or a passing signal, the circuit returns for activation (box 230). Accordingly, since the base unit and the valve unit receive data from the temperature sensor / transmitter independently of one another, the invention can be implemented in different ways. For example, the base unit may be omitted, where the water temperature is not presented to the user. In addition, the valve unit can be omitted, wherein only the water temperature is presented to the user. Preferably, the valve unit is also provided with a rotary switch, which allows the user to set the value of the closing temperature to discrete levels. Similarly, in order to facilitate installation in an environment where multiple units can be installed close to one another, the temperature sensor and transmitter and the valve unit are preferably provided with a frequency selector in order to allow the operation of adjacent units at different frequencies in order to minimize the risk of interference. In certain facilities, such as residential care facilities, old homes, care facilities and schools, full-time burn protection may be desired. Accordingly, units can be constructed, which do not allow the device to be deactivated against burns. In other facilities, such as residential houses, it may be desirable to provide an operator with the ability to switch to safety firing mode as indicated above.

Since the modalities described above contemplate a radio frequency link between the sensor / transmitter 16, the controller 18 and the valve unit 20, other wireless links such as LEDs, infrared or sound links can be used. The terms and expressions, which have been used in that specification, are used as terms of description and not limitation, and there is no intention in the use of such terms and expressions to exclude any equivalent of the aspects shown and described or portions of the same, but it is recognized that several modifications are possible within the scope of the claims.
