Upper and lower heating elements 118, 119 (
Water heater appliance 100 also includes an inlet or cold water conduit 104 and an outlet or hot water conduit 106 that are both in fluid communication with a chamber or interior volume 114 (
Water heater appliance 100 extends longitudinally between a top portion 108 and a bottom portion 109 along a vertical direction V. Thus, water heater appliance 100 is generally vertically oriented. Water heater appliance 100 can be leveled, e.g., such that casing 102 is plumb in the vertical direction V, in order to facilitate proper operation of water heater appliance 100. A drain pan 110 is positioned at bottom portion 109 of water heater appliance 100 such that water heater appliance 100 sits on drain pan 110. Drain pan 110 sits beneath water heater appliance 100 along the vertical direction V, e.g., to collect water that leaks from water heater appliance 100 or water that condenses on an evaporator 128 (
Sealed system 120 may include a compressor 122, a first condenser 124, a second condenser 126 and an evaporator 128. Compressor 122 and/or evaporator 128 of sealed system 120 may be disposed within casing 102 at top portion 108 of water heater appliance 100. As is generally understood, various conduits may be utilized to flow refrigerant between the various components of sealed system 120. Thus, e.g., evaporator 128 may be between and in fluid communication with second condenser 126 and compressor 122. During operation of sealed system 120, refrigerant may flow from evaporator 128 through compressor 122. For example, refrigerant may exit evaporator 128 as a fluid in the form of a superheated vapor and/or high quality vapor mixture. Upon exiting evaporator 128, the refrigerant may enter compressor 122. Compressor 122 may be operable to compress the refrigerant. Accordingly, the pressure and temperature of the refrigerant may be increased in compressor 122 such that the refrigerant becomes a superheated vapor.
Each condenser 124, 126 may be assembled in a heat exchange relationship with tank 112 in order to heat water within interior volume 114 of tank 112 during operation of sealed system 120. First condenser 124 may be positioned downstream of and in fluid communication with compressor 122, and may be operable to heat the water within interior volume 114 using energy from the refrigerant. For example, the superheated vapor from compressor 122 may enter first condenser 124 wherein it transfers energy to the water within tank 112 and condenses into a saturated liquid and/or liquid vapor mixture. Second condenser 126 may be positioned downstream of and in fluid communication with first condenser 124, and may additionally be operable to heat the water within interior volume 114 using energy from the refrigerant, such as by further condensing the refrigerant.
Sealed system 120 may also include a first throttling device 130 between first condenser 124 and second condenser 126, and/or a second throttling device 132 between second condenser 126 and evaporator 128. Refrigerant, which may be in the form saturated liquid vapor mixture, may exit first condenser 124 and travel through first throttling device 130 before flowing through second condenser 126. First throttling device 130 may generally expand the refrigerant, lowering the pressure and temperature thereof. The refrigerant may then be flowed through second condenser 126. Similarly, refrigerant, which may be in the form of high quality/saturated liquid vapor mixture, may exit second condenser 126 and travel through second throttling device 132 before flowing through evaporator 128. Second throttling device 132 may generally expand the refrigerant, lowering the pressure and temperature thereof. The refrigerant may then be flowed through evaporator 128.
First and second throttling devices 130, 132 may be any suitable components for generally expanding the refrigerant. For example, in some exemplary embodiments, first and second throttling device 130, 132 may be a Joule-Thomson expansion valve, also known as a “J-T valve.” In other exemplary embodiments, first and second throttling device 130, 132 may be an ejector. In still other exemplary embodiments, a capillary tube, fixed orifice, or other suitable apparatus may be utilized as first and second throttling device 130, 132.
Water heater appliance 100 may additionally include a temperature sensor 152. Temperature sensor 152 may be configured for measuring a temperature of water within interior volume 114 of tank 112. Temperature sensor 152 can be positioned at any suitable location within water heater appliance 100. For example, temperature sensor 152 may be positioned within interior volume 114 of tank 112 or may be mounted to tank 112 outside of interior volume 114 of tank 112. Temperature sensor 152 may further be positioned within upper portion 160 or lower portion 162. When mounted to tank 112 outside of interior volume 114 of tank 112, temperature sensor 152 can be configured for indirectly measuring the temperature of water within interior volume 114 of tank 112. For example, temperature sensor 152 can measure the temperature of tank 112 and correlate the temperature of tank 112 to the temperature of water within interior volume 114 of tank 112. Temperature sensor 152 may be any suitable temperature sensor. For example, temperature sensor 152 may be a thermocouple or a thermistor.
Water heater appliance 100 may further include a controller 150 that regulates operation of water heater appliance 100. Controller 150 may be, for example, in operative communication with sealed system 120 (such as compressor 122, and/or other components thereof), auxiliary heating elements, and/or temperature sensor 152. Thus, controller 150 can selectively activate system 120 and/or auxiliary heating elements in order to heat water within interior volume 114 of tank 112.
Controller 150 includes memory and one or more processing devices such as microprocessors, CPUs or the like, such as general or special purpose microprocessors operable to execute programming instructions or micro-control code associated with operation of water heater appliance 100. The memory can represent random access memory such as DRAM, or read only memory such as ROM or FLASH. The processor executes programming instructions stored in the memory. The memory can be a separate component from the processor or can be included onboard within the processor. Alternatively, controller 150 may be constructed without using a microprocessor, e.g., using a combination of discrete analog and/or digital logic circuitry (such as switches, amplifiers, integrators, comparators, flip-flops, AND gates, and the like) to perform control functionality instead of relying upon software.
As may be seen in
Support ring 200 has or defines an outer perimeter OP and an inner perimeter IP when support ring 200 is in the closed configuration (
Support ring 200 may be constructed of or with any suitable material. For example, support ring 200 may be constructed of or with expanded polystyrene. In particular, first segment 210 and second segment 220 may be formed of separate or discrete pieces of expanded polystyrene and mounted to each other.
As may be seen in
Second segment 220 of support ring 200 also extends between a hinge portion 222 and a locking portion 224, e.g., along the circumferential direction. Thus, hinge portion 222 and locking portion 224 of second segment 220 may be spaced apart from each other along the circumferential direction C on casing 102 of water heater appliance 100. Hinge portion 222 and locking portion 224 of second segment 220 may be spaced apart from each other by any suitable distance along the circumferential direction C. For example, hinge portion 222 and locking portion 224 of second segment 220 may be spaced apart from each other by about one hundred and eighty degrees along the circumferential direction C. In such a manner, hinge portion 222 and locking portion 224 of second segment 220 may be positioned opposite each other on casing 102 of water heater appliance 100.
As may be see in
Hinge portion 212 of first segment 210 may also include an end wall 217. Cylinder 216 of first segment 210 may be mounted to and/or positioned at end wall 217 of first segment 210. Hinge portion 222 of second segment 220 may also include an outer projection 227. Outer projection 227 of second segment 220 is positioned on or contacts end wall 217 of first segment 210 when support ring 200 is in the open configuration. Conversely, outer projection 227 of second segment 220 is spaced apart from end wall 217 of first segment 210 when support ring 200 is in the closed configuration. In such a manner, outer projection 227 and end wall 217 may permit and limit pivoting of first and second segments 210, 220 relative to each other. In particular, outer projection 227 may act as a stop to limit pivoting of first and second segments 210, 220 relative to each other.
