Definitions

  • the present invention relates to the field of domestic gas appliances, and more particularly to hydraulic systems of gas water heating appliances.
  • a user When turning on a hot faucet to start a gas water heating appliance, such as a gas water heater, a user often has to wait a long time for hot water output from the hot faucet. This is because, on one hand, there is a large amount of cold water staying in water pipelines within or outside of the appliance, especially for the gas-fired appliance with a small buffer tank that stores water, and this amount of cold water has to be drained out first and then hot water comes out; on the other hand, at the beginning of starting the gas water heater, for consideration of security, a blower will be first activated to exhaust residual gas within a combustion chamber and flue pipes, and the combustion burner will be ignited after the residual gas being all replaced by fresh air, during the period, hot faucet continuously outputs cold water. Obviously, the big volume of drained cold water causes the waste of water resources. In addition, this will lead to a poor user experience, for example, when the user desires to take a shower in winter, the user has to wait a long time to get hot water.
  • a gas water heating appliance including a housing, a burner, a heat exchanger, and a pipe assembly.
  • the pipe assembly includes incoming pipelines located at upstream of the heat exchanger and outgoing pipelines located at downstream of the heat exchanger.
  • a water tank is disposed in the outgoing pipelines, and the water tank includes an electric heating device contained therein.
  • the incoming pipelines has an inlet pipe section, and the pipe assembly further includes a circulation pipe section disposed in parallel with the inlet pipe section, and a circulation pump is disposed in the circulation pipe section.
  • the appliance further includes a timer disposed in the housing, and the circulation pump starts working on a time preset by the timer.
  • the appliance further includes a controller disposed in the housing for controlling the operation of the burner to heat cold water to a predetermined target outlet temperature.
  • the timer is independent of the controller.
  • the controller activates the circulation pump on the preset time and ignites the burner on detecting water flow within the pipelines reaches or exceeds a threshold.
  • the appliance further includes a temperature sensor associated with the incoming pipelines, and the controller controls the operation of the burner according to the predetermined target outlet temperature, a real outlet temperature, and a temperature detected by the temperature sensor.
  • the temperature sensor is disposed at a common pipe section communicating with both the inlet pipe section and the circulation pipe section.
  • the appliance further includes a pressure regulating device associated with the incoming pipelines or the outgoing pipelines.
  • the pressure regulating device is a pressure relief valve or an expansion vessel.
  • the circulation pump By employing the circulation pump, cold water accumulated in the pipelines and the water tank of the gas water heating appliance can be preheated, thereby providing instant hot water when users turn on the hot faucet.
  • the timer since the timer is disposed independently of the controller, it can activate the circulation pump without assistance of the controller, in other words, the timer and the circulation pump can be added to any gas water heating appliances to realize the preheating function without modifications to the existing electric circuit boards.
  • Gas water heating appliances could be fired with combustible gas, such as natural gas, city gas, liquefied petroleum gas, methane, etc., thereby supplying hot water and/or heating living space for domestic sanitary usage and heating purpose, such as gas water heaters and/or gas boilers.
  • combustible gas such as natural gas, city gas, liquefied petroleum gas, methane, etc.
  • a gas water heater will be exemplified hereinafter.
  • a gas water heater 1 includes a housing 10, and a burner 11, a heat exchanger 13, a flue hood 14, an air supply fan 15 all contained in the housing 10, and flue pipes.
  • the flue pipes can take the form of annular tubes, that is, the flue pipes define an outer passageway 161 for being passed through by incoming air and an inner passageway 162 for being passed through by exhausting flue gas.
  • the external air is introduced in via the outer passageway 161 by the air supply fan 15 and mixed with incoming gas so as to together feed to the burner 11.
  • the mixture of gas and air is ignited in the burner 11 and combusted in the combustion chamber 12 defined by the burner 11 and the heat exchanger 13.
  • the combustion gas at a high temperature is driven by the air supply fan 15 to pass through the heat exchanger 13, and cold water flowing in tubes surrounding an outer casing of the heat exchanger 13 is heated to be hot water.
  • the flue gas is collected by the gas hood 14 and discharged out through the inner passageway.
  • a pipe assembly is disposed in the housing 10 and connected with the heat exchanger 13.
  • the pipe assembly includes incoming pipelines located upstream of the heat exchanger 13 and outgoing pipelines located downstream of the heat exchanger 13.
  • the outgoing pipelines includes a first outgoing pipe 34 connected with the heat exchanger 13 and a second outgoing pipe 35 connected with external pipelines 42.
  • a water tank 17 is disposed between the first and the second outgoing pipes 34, 35, and an electric heating device 171 is disposed in the water tank 17.
  • the electric heating device 171 can be an electric heating rod or an electric tracing band.
  • the incoming pipelines includes an inlet pipe section 32 connected with water main pipelines 41, a circulation pipe section 31 disposed in parallel with the inlet pipe section 32, and a common pipe section 33.
  • the common pipe section 33 has one end communicated with both the inlet pipe section 32 and the circulation pipe section 31, and the other end communicated with tubes surrounding the heat exchanger 13.
  • a circulation pump 21 is disposed in the circulation pipe section 31.
  • a timer 22 and a controller 24 are both disposed in the housing 10.
  • the controller 24 may be a logic control circuit consists of a number of electronic components, or may incorporate a Micro Controller Unit (MCU). Of course, the controller can also use other types of integrated circuits, such as Field Programmable Gate Array (FPGA) etc..
  • the timer 22 is an electronic timer, and it can turn on the power based on users' settings.
  • the timer 22 can be independent of the controller 24, and it has a user interface for being input settings by users.
  • the circulation pump 21 When a pre-set time arrives, the circulation pump 21 is activated, and the controller 24 can detect a water flows via a flow sensor (not shown), thereby taking appropriate actions, which will be described in details hereinafter.
  • the advantage of the timer 22 being independent of the controller 24 is that, the timer 22 and the circulation pump 21 can be added to any gas water heating appliances to realize appropriate functions which will be described without modification to the existing electric circuit boards. It should be apparent to those skilled in the art that, the timer 22 can also communicate with the controller and let the controller 24 control the circulation pump, however, the control circuit has to be modified in this case.
  • a user can set the timer 22 to pre-heat cold water accumulated in the pipe assembly and the water tank 17 of the gas water heater 1, so that the user can enjoy instant hot water when the hot faucet is turned on. For example, the user intends to take a shower at nine o'clock in the evening, so he can set the timer 22 to start the appliance to work at a pre-heat mode at eight forty-five in the evening in advance.
  • the circulation pump 21 is energized, and in the meantime, the controller 24 can sense a water flow within the pipelines via the flow sensor. When the water flow reaches or exceeds a lower threshold, e.g. 2.2 L/min, the related components will be activated to work, like the air supply fan and the combustion burner.
  • water flow passes through the circulation pipe section 31, the common pipe section 33, the heat exchanger 13, the first outgoing pipe 34, the water tank 17, the second outgoing pipe 35, the external pipelines 42, 43 and returns to the circulation pipe section 31.
  • the circulation of water flow repeats till the temperature of water reaches a pre-determined outlet temperature and maintain at this temperature.
  • a temperature sensor 23 can be associated with the incoming pipelines, preferably, the temperature sensor 23 is disposed at the common pipe section 33.
  • the gas water heater 1 enters a normal heating mode, and cold water introduced from the water main pipelines 41 passes through the inlet pipe section 32 and enters the common pipe section 33.
  • the circulation pump 21 can stop working, or continue to work. If the circulation pump 21 continues to work, the water passing through the circulation pipe section 31 will enter the common pipe section 33 and merges with the cold water from the incoming pipe section 32.
  • the controller 24 could not control the operation of the appliance based on the temperature of inlet water coming from the water main pipelines 41.
  • the temperature detected by the temperature sensor 23 can be regarded as the temperature of inlet cold water for being used by the controller to control appropriate operations of the appliance.
  • the controller 24 may continuously adjust combustion power of the burner according to the temperature detected by the temperature sensor 23, a real outlet temperature that can be detected by another temperature sensor (not shown) disposed at water outlet, and a predetermined target outlet temperature.
  • the pressure regulating device can be disposed in the incoming pipelines or the outgoing pipelines, in this embodiment, the pressure regulating device 25 is disposed at the second outgoing pipe 35 before hot water outlet, and it can be a pressure relief valve. When the pressure within the pipelines is larger than certain threshold, the pressure relief valve will automatically open to drain a part of water, so that the pressure within the pipelines can be back to a balance value.
  • the pressure regulating device can be an expansion vessel that also play a role in regulating the internal pressure of the pipelines.
  • the circulation pump By employing the circulation pump, cold water accumulated in the pipelines and the water tank of the gas water heating appliance can be preheated, thereby providing instant hot water when users turn on the hot faucet.
