The remote control device may include a case, a display, an RF transmitter, electronic circuitry, a microprocessor and a power supply connection. The base unit and space heater may include a container, an RF receiver, a variable flow control circuit, a status detection circuit, heater connection circuitry, electronic circuitry, a microprocessor, power supply, and heating elements. The remote control device transmits command controls to the base unit, and the base unit modulates the quantity of gas or electric current flowing through the space heater in accordance with the command controls.
Description
- The present invention relates to space heater control devices, and more specifically to a RF-signal, space heater remote control system.
- The fundamental aspects of space heaters are well-known in the art. A space heater typically generates heat in one of two ways: either flammable gas is combusted or electricity passes through resistive wiring. A typical heater assembly may house a source of heat, i.e., a heating device, a power source or a connection to a power source, and a control device. A fan integral to the heater may be used to circulate air in a room past the heating elements. An electrical heater, for example, may include electrical heating elements, an electrical cord, an electrical fan and a power switch. After connecting the electrical cord to a wall outlet, engaging the power switch may activate the electrical fan and the electrical heating elements. The fan may force air past the heating elements, heating the air by convection.
- A parasol heater is a particular variety of space heater that typically is a portable gas combustion heater commonly used for patios and other outdoor venues. A parasol heater commonly includes a trunk containing a gas tank, a pillar extending above the trunk, and an inverted burner assembly atop the pillar that combusts gas flowing through the pillar from the tank. Heating controls are often located on the trunk or the pillar. Parasol heaters are used to heat the preselected area surrounding the heater insofar as the burning assembly generally has a circular, umbrella-like shape that radiates heat down and around the heater.
- Whether using a gas heater or an electric heater, the amount of heat generated depends on many factors, but two primary variables are the amount of gas or electricity allowed to flow through the heater, affecting the intensity of the heat, and the duration of the flow. Typically, a control device is used to regulate the intensity and duration of heat generated. The duration of heat generation generally is dependent on the time during which the heater is turned on.
- A simple ON/OFF power switch is a basic control device, in that a presumably fixed amount of gas or electricity passes through the heater while the control device is in the ON state, generating a relatively constant intensity of heat. In a gas heater, igniting the reactants normally starts the reaction. Ignition usually requires a flame (e.g., a pilot light) or a spark, which may be induced, for example, by an electrical ignition combined with the power switch. Apart from residual heat dissipation, no heat is generated in the OFF state. More sophisticated control devices have used timers to alternate between the ON and OFF states, effectively regulating relative heat generation by controlling the duration of heat generation, without altering the amount of gas or electricity passing through the heater while in the ON state.
- Another means of controlling the relative heat generation while the heater is turned on is to marginally adjust the flow of gas or electricity within the heater through the use of a variable flow control, analogous to a dimmer switch. Increments of gaseous or electric flow adjustment may be coarse, such as with control settings of Low and High, or relatively fine, such as with settings of 1 to 10, with 1 corresponding to the lowest intensity of heat and 10 corresponding to the highest intensity of heat. Relative heat generation in this context is dependent on energy consumption, independent of the ambient temperature near the heater.
- Space heater control devices may also regulate heat generation by means of a thermostat in conjunction with a variable flow control device. Whereas a simple variable flow control device operating by itself may maintain a constant gaseous or electric flow in the heater, a thermostat may use a variable flow control to maintain a constant heater temperature by varying the gaseous or electric flow in the heater. Ambient temperatures around the heater will affect the heater temperature as heat is exchanged between them. The use of a fan for air circulation will also affect the exchange of heat. As ambient temperatures rise or fall, the thermostat may decrease or increase, respectively, the flow of gas or electricity to the heater to maintain a desired temperature.
- Remote control systems are also well-known in the art. Two popular methods of remote control involve infrared (IR) signals and radio frequency (RF) signals. Infrared signals are easily absorbed by objects in their path, so IR remote control devices require a direct, unobstructed line-of-sight between the IR remote control device and the base IR receiver. Most television remote control systems, for example, use IR remote control devices.
- Remote control systems that do not use IR signaling typically may use other RF signals that are not easily absorbed by objects in their path. RF remote control devices generally do not require a direct, unobstructed line-of-sight between the RF remote control and the base RF receiver. Therefore, an RF remote control may be operated to control a base unit from almost any location within the effective range of the RF transmission. The effective range of the RF transmission will depend largely on the strength and frequency of the signal. Garage door openers, for example, typically use RF remote control systems.
- Therefore, it would be advantageous to design a portable space heater having a remote control system that incorporates many of the benefits of previous space heater control devices in a remote control system using RF signaling.
- The present invention relates to a portable space heater having a remote control device, and more specifically to a RF-signal, space heater remote control system having a display. A space heater remote control system according to the present invention may include a remote control device and a base unit. The remote control device may include a case, a display, an RF transmitter or transceiver, electronic circuitry, a thermostat, a microprocessor and a battery power supply connection. The base unit may include a container, an RF receiver or transceiver, a variable flow control circuit, a status detection circuit, heater connection circuitry or valve, electronic circuitry, a microprocessor, a power supply, and possibly an electric ignition.

- Other features and advantages of the present invention will be apparent from the following description of the exemplary embodiments thereof, and from the claims.
- A space heater remote control system according to the present invention may include a
remote control device 100 and abase unit 200 coupled tospace heater 300. Referring to the figures, FIG. 1A shows a block diagram of a space heaterremote control device 100 according to an exemplary embodiment of the present invention. Theremote control device 100 may include a case 110 (shown in FIGS. 2 and 3), akeypad 120, anRF interface assembly 140,electronic circuitry 150, amicrocontroller 160 and apower supply 170. Theremote control device 100 also may include anoptional display 130. - As shown in FIG. 1A, the
microcontroller 160 may be coupled to each of thekeypad 120, thedisplay 130, theRF interface assembly 140, and thepower supply 170. Themicrocontroller 160 may include, for example, a central processing unit (CPU) 161, read-only memory (ROM) 162, random-access memory (RAM) 163, aninput port 164, anoutput port 165, and adisplay driver 166. Furthermore, theinput port 164 interfaces thekeypad 120 with theCPU 161, the output port interfaces theRF interface assembly 140 with theCPU 161, and thedisplay driver 166 interfaces thedisplay 130 with theCPU 161. - The
keypad 120 may include abacklight 122. Likewise, thedisplay 130 may include abacklight 132. Thebacklight 132 may be implemented, for example, with LED or LCD displays. TheRF interface assembly 140 may include anRF transmitter 141 connected to anantenna 142. Thepower supply 170 may include, for example, a battery bay to hold 2 “AAA” sized batteries. Alternatively, thepower supply 170 may include a rechargeable power cell that is recharged by a separate recharger assembly, which could be attached by a detachable recharger cord. - Although not shown in FIG. 1A, the
remote control 100 also may include a thermostat having a thermometer with whichremote control 100 measures the ambient temperature. Theremote control 100 therefore may display the ambient temperature on theoptional display 130. Furthermore, the system may use the ambient temperature instead of the heater temperature as a variable in adjusting the heat intensity level applied by thebase unit 200. Thus, the thermostat may compensate the heater heat level for the ambient room temperature. First, the thermometer may measure the ambient temperature, and second, the thermostat may apply temperature compensation to the heat level commands sent to thebase unit 200 to maintain constant heater temperature as the ambient temperature varies. An algorithm stored in theremote control 100 may calculate how much to adjust the heat level relative to the ambient temperature to maintain a desired heater temperature. - Likewise, the thermostat, thermometer, and the algorithm may be located on the
base unit 200 instead of on theremote control device 100, but this would require that theremote control device 100 be able to receive data transmitted by thebase unit 200 in order for thedisplay 130 of theremote control device 100 to show the ambient temperature measured at thebase unit 200. Such a configuration would require the use of RF transceivers in both theremote control device 100 andbase unit 200, as discussed in detail below. If RF transceivers are used, the thermometer may be separated from the thermostat and the algorithm, allowing for the ambient temperature data to be compiled at one place and transmitted to another place. Alternatively, thedisplay 132 on theremote control device 100 may show the temperature at the remote and not at theheater 300. Thebase unit 200 may include the thermostat while theremote control 100 sends thebase unit 200 desired temperature settings to adjust the thermostat. - By comparison, FIGS. 1B and 1C show block diagrams of a space
heater base unit 200 coupled to aspace heater 300 according to exemplary embodiments of the present invention. Thebase unit 200 and thespace heater 300 may be housed together or separately. Thebase unit 200 may include anRF interface assembly 210, amicrocontroller 220,electronic circuitry 230,power supply 240,heater connection circuitry 250, astatus detection circuit 260, and a variableflow control circuit 270. Thespace heater 300 may include, among other things,heating elements 310 and afan 320. In particular, thespace heater 300 may employ either only anelectric power supply 242, as shown in FIG. 1B, to power both the electronics and theheating elements 310, or anelectric power supply 242 in combination with agas power supply 243, as shown in FIG. 1C, theelectric power supply 242 to power the electronics and thegas power supply 243 to power theheating elements 310. - In any event, electric power is necessary to operate the electronic components of the
base unit 200. This electric power may come from either a power line connection, such aselectric power supply 242 as shown in FIG. 1B, or abattery 244, as shown in FIG. 1C. In the event that a power line connection is used, thespace heater 300 must remain within reach of an electrical outlet to be used, and theheating elements 310 just as well may use electric power. Use of abattery 244 to power the electronics lends itself to using agas power supply 243 so as to facilitate increased portability of thespace heater 300. - As shown in FIGS. 1B and 1C, the
microcontroller 220 may be coupled via theelectronic circuitry 230 to each of theRF interface assembly 210, thepower supply 240, theheater connection circuitry 250, thestatus detection circuit 260, and the variableflow control circuit 270. Themicrocontroller 220 may include, for example, a central processing unit (CPU) 221, read-only memory (ROM) 222, random-access memory (RAM) 223,input ports 224, and anoutput port 225. Furthermore, theinput ports 224 interface theRF interface assembly 210 and thestatus detection circuit 260 with theCPU 221, and theoutput port 225 interfaces the variableflow control circuit 270 with theCPU 221. - The
RF interface assembly 210 may include anRF receiver 211 connected to anantenna 212. As in FIG. 1B, thepower supply 240 may include an alternating current-to-direct current (AC/DC)converter 241 and apower cord 242 adapted to plug into a power outlet. The AC/DC converter 241 supplies a direct current to themicrocontroller 220. In the event of anelectric space heater 300, thepower supply 240 may provide 120V AC to the variableflow control circuit 270 that regulates electricity to theheating elements 310 andfan 320 via theheater connection circuitry 250 which couples thebase unit 200 to theheater 300. For easier disassembly and storage,power cord 242 may attach and detach from thebase unit 200 and theheater 300. - The variable
flow control circuit 270 interfaces thepower supply 240 with theheater connection circuitry 250. In anelectric heater 300, the variableflow control circuit 270 may modulate the duty cycle of the power supplied to theheater 300. In agas heater 300, the variableflow control circuit 270 electronically controls an electricgas control assembly 330. The electricgas control assembly 330 may include anelectric ignition 331 to ignite the gas, thereby turning on the heater, and agas regulator valve 332 to increase or decrease the flow of gas to theheating elements 310, thereby adjusting the power supplied to theheater 300. By remotely activating theelectric ignition 331, the user may remotely turn on theheater 300. Likewise, by remotely deactivating thegas regulator valve 332, the user may remotely turn off theheater 300. Marginal or incremental adjustments of the gas flow made from either the remote 100 or thebase unit 200 may permit the user to better control heat output of the heater to conform to the desired comfort of the user. - The
status detection circuit 260 may monitor heater sensors (not shown) or it may simply monitor the electrical feed-back from the power supplied by the variableflow control circuit 270. If for example thestatus detection circuit 260 detects a drop in resistance that may indicate a local short circuit, thestatus detection circuit 260 may inform themicrocontroller 220 which in turn may deactivate theheater 300. Also, thestatus detection circuit 260 may monitor, for example, the gas pressure inside thegas canister 243 and warn the user if the pressure is too low or too high. - In the event that the remote control system intends to have the
remote control device 100 receive data transmitted from thebase unit 200 as well as have thebase unit 200 receive data transmitted from theremote control device 100,RF transmitter 141 of FIG. 1A andRF receiver 211 of FIGS. 1B and 1C may be replaced with RF transceivers (not shown) coupled to both the input and output ports, respectively 164, 165 and 224, 225. The use of RF transceivers would permit thebase unit 200 to communicate the status of theheater 300 to theremote control device 100. - For example,
base unit 200 could inform theremote control device 100 that theheater 300 is not coupled to thebase unit 200, preventing the execution of any instructions received from theremote control device 100. Similarly, for example, if a battery were coupled to thebase unit 200, thebase unit 200 would have power to inform theremote control 100 that thepower supply 240 is not available, either becausepower cord 242 is unplugged or becausegas canister 243 is detached or empty. Thebase unit 200 could also relay intermediate status information to theremote control device 100. For example, theheater 300 may include a heater thermometer coupled to thestatus detection circuit 260, allowing thebase unit 200 to transmit the current heater temperature compared to the programmed heater temperature. Similarly, thestatus detection circuit 260 may measure the electrical resistance of theheater 300, and themicrocontroller 220 may calculate the current heater temperature using a temperature algorithm dependent on the measured electrical resistance of theheater 300 relative to the electrical power supplied to theheater 300. - FIGS. 2 and 3 respectively show a perspective view and a plan view of a space heater
remote control device 100 according to an exemplary embodiment of the present invention. Thecase 110 may house thekeypad 120, thedisplay 130, the RF interface assembly 140 (shown in FIG. 1A), the electronic circuitry 150 (shown in FIG. 1A), the microcontroller 160 (shown in FIG. 1A) and the power supply 170 (shown in FIG. 1A). Thekeypad 120 may includebuttons 121 and a keypad backlight 122 (shown in FIG. 1A) to illuminate thebuttons 121. Thedisplay 130 may include a multifunctional,digital LCD 131 and a display backlight 132 (shown in FIG. 1A). - FIG. 4 shows a partial cut-away perspective view of a
heater base unit 200 housed in a gas-operated parasol-style space heater 300′ according to an exemplary embodiment of the present invention. Theparasol heater 300′ as shown includes atrunk 350 containing agas tank 351, apillar 360 extending above thetrunk 350, and aninverted burner assembly 370 atop thepillar 360 that combusts gas flowing through thepillar 360 from thetank 351. Heating controls are often located on thetrunk 350 or thepillar 360, shown here within thecontainer 280 the houses thebase unit 200. Theparasol heater 300′ also may include a light 380, such as anelectric light 381 or agas light 382, that also may be controlled by theremote control 100 via thebase unit 200. - As also shown in FIG. 5, the
container 280 may house theRF interface assembly 210, themicrocontroller 220,electronic circuitry 230, thepower supply 240, theheater connection circuitry 250, the status detection circuit 260 (shown in FIG. 1C), and the variable flow control circuit 270 (shown in FIG. 1C). By comparison, FIG. 5 shows a partial cut-away perspective view of a spaceheater base unit 200 housed in a gas-operated catalytic-style space heater 300″ according to an exemplary embodiment of the present invention. - Shown in FIGS. 4 and 5, the
base unit 200 also may include one ormore LED indicators 281 and a sound generator 282, both of which are coupled tomicrocontroller 220. In the event that thebase unit 200 separately controls theheater elements 310 and thefan 320, twoLED indicators 281 may indicate the independent activation of theheater elements 310 or thefan 320. TheLED indicator 281 may luminesce when the associatedspace heater 300 is activated. The sound generator 282 may beep or chirp to acknowledge reception of instructions from theremote control 100 or to sound an alarm signaled by thestatus detection circuit 260. The sound generator 282 may comprise a loudspeaker, a piezoelectric element, or the like. - Given the intelligence of
microcontrollers display 130. TheLCD 131 may have fixedfields 133 andvariable fields 134 that are activated when the associated function is being programmed and displayed. For example, a preheat function may be displayed by a fixedfield 133 to indicate that the preheat function is active or being programmed. Conversely, a clock function requires avariable field 134 to display the passage of time. As shown in FIGS. 2 and 3, anexemplary LCD 131 may display information regarding the status of, among others, the power (On/Off/Auto), heating level, the time, heating times, and the heating duration. - As discussed, a space heater control device may employ several different methods to regulate the heating of the
heater 300. In conjunction with themicrocontroller 160 of theremote control 100, themicrocontroller 220 of thebase unit 200 may regulate the heating of aheater 300 coupled to thebase unit 200. A user may input a desired heating regime into theremote control 100, and theremote control 100 may program thebase unit 200 accordingly. Alternatively, all the programming may reside in theremote control 100. Thebase unit 200 may regulate the heating of aheater 300 by varying start and stop times, the duration of the heating, the intensity level of the heat, and the desired temperature of theheater 300. - By combining two or more of these variables, the
base unit 200, for example, may preheat aheater 300 quickly to a desired temperature or level by applying the maximum heat for a short period until the desired status is reached and then reducing the heat to maintain the desired status. Similarly, thebase unit 200 may intermittently heat theheater 300 over a longer period, possibly to conserve power and maintain a desired temperature. Intermittent ramping of heat may generate heat more efficiently with less excess, avoid overheating theheater 300, and prolong the life of theheater 300. - A number of embodiments of the present invention have been described above. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the invention. Accordingly, other embodiments are within the scope of the following claims. It is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. It is also understood that the following claims are intended to cover all of the generic and specific features of the invention herein described and all statements regarding the scope of the invention.
