Description

Water heating device

Technical Field

The embodiment of the invention relates to the field of water heaters, in particular to a water heating device.

Background

The existing outdoor gas water heater is inconvenient to adjust the temperature on an outdoor unit because the existing outdoor gas water heater is arranged outdoors, so that the scheme of an external wiring controller is generally adopted. But the line controller is higher in cost, longer in wiring and inconvenient to install due to the fact that the wall needs to be penetrated. When some users need to adjust the temperature, the outdoor unit panel shell is opened, and a display is connected externally to adjust the temperature, but the operation is very inconvenient, and the cost is increased. Similarly, the temperature adjustment by adopting a wireless method is easily influenced by external factors such as electrostatic shielding, distance, signals and the like.

Disclosure of Invention

The present invention is directed to solving at least one of the problems of the prior art or the related art.

In view of the above, the present invention provides an embodiment of a water heating apparatus.

In order to achieve the above object, an embodiment of the present invention provides a water heating apparatus including: the heating device comprises a heating body, wherein a water tank and a heating device for heating the water tank are arranged in the heating body; the controller is electrically connected with the heating device and can control the water outlet temperature of the heating body; the code dialing device is electrically connected with the controller, comprises a plurality of code dialing switches, a plurality of gears are formed according to the opening and closing states of each code dialing switch, and the controller can control the water outlet temperature according to the gears of the code dialing device.

The water heating device comprises a heating body and a controller, wherein a water tank and a heating device are arranged in the heating body. The water tank is used for storing water to be heated so that the heating device can heat the water in the water tank, and the controller can control the water outlet temperature of the water tank.

In this scheme, the controller is connected with heating device electricity, and the user can set for the controller temperature through the code dialing ware, and then sets for hot water system's play water temperature. The code dialing device is simple in structure, stable and durable, free of environmental interference, and stable in water temperature setting through the code dialing device for a hot water device which does not need to frequently adjust water outlet temperature.

The dial is provided with a plurality of dial switches, and a plurality of gears can be formed according to the opening and closing states of the dial switches. Different gears may correspond to different operating states or temperature values. Therefore, the outlet water temperature of the water heating device can be adjusted within a certain range, so that the water heating device is suitable for scenes with low temperature adjusting frequency.

In particular, it is inconvenient to set the outlet temperature value for a water heater installed outdoors. The wire controller needs to penetrate through the wall, and a wireless method is adopted, so that the wire controller is easily interfered by the environment. In this case, the dial indicator can be installed outdoors, and the temperature value can be set through the dial indicator, so as to keep the outlet water temperature of the hot water device always stable at the temperature set by the user. If the water outlet temperature needs to be adjusted, the dial switch of the dial indicator is only needed to be adjusted to the corresponding water outlet temperature.

In addition, the water heating device in the above scheme provided by the invention can also have the following additional technical characteristics:

among the above-mentioned technical scheme, heating device includes auxiliary heater and combustor, and auxiliary heater is used for heating water to send the water tank with the water after the heating, hot water system still includes: and the water temperature sensor is used for detecting the water inlet temperature of the water flowing into the water tank, and the controller is also used for controlling the combustor to work when the water inlet temperature is lower than the first temperature.

In this technical scheme, heating device includes auxiliary heater and combustor, and these two can heat water, and specifically, auxiliary heater heats the water before flowing into the water tank, sends into the water tank after the heating to slow down the intensification pressure of combustor, in the water tank, heats through the combustor again, until the temperature reaches the temperature that the user set for.

When the water heated by the auxiliary heater flows into the water tank, the water temperature sensor can detect the water inlet temperature of the water in the water tank, namely the temperature of the water sent into the water tank from the auxiliary heater. The controller can judge whether the temperature of the inlet water reaches the first temperature, and if the temperature of the inlet water reaches the first temperature, the water in the water tank can be provided for a user without being heated again. If the water temperature sensor detects that the temperature of the inlet water does not reach the first temperature, the burner can be started to work, and the water is heated and then is provided for a user to use. Through the secondary heating of the burner, the outlet water temperature can be ensured to meet the use requirements of users no matter whether the heating temperature of the auxiliary heater reaches the temperature set by the users.

The first temperature is the temperature which the auxiliary heater is sent into the water tank to reach, namely the preset temperature.

In the above technical scheme, the auxiliary heater is a solar heater.

In the technical scheme, the auxiliary heater is selected as the solar heater, so that the water can be heated by solar energy, and the solar water heater is more economic and environment-friendly and saves energy compared with methods such as electric heating and gas heating.

The heating effect of the solar heater is greatly influenced by weather. Under the condition of sufficient sunlight irradiation, the heating effect is very good. In winter or cloudy days and the like, when the sunlight irradiation is weak, the heating effect is not obvious. Therefore, in this embodiment, the solar heater is set as the auxiliary heater. When the temperature of the water fed into the water tank by the solar heater does not reach the first temperature, the controller starts the burner to heat the water again.

In the above technical solution, the outlet water temperature includes a plurality of temperature intervals, and each gear of the dial indicator is associated with the outlet water temperature in one temperature interval.

In the technical scheme, the outlet water temperature comprises a plurality of different temperature intervals, and the hot water device can set the temperature interval to be used currently. Different temperature intervals represent different temperature ranges, and when the gear is adjusted to each gear, the corresponding temperature interval can be determined.

It is necessary to supplement that, after the temperature interval is determined, the temperature of the temperature interval can be refined through the gear position of the dial. Each gear of the code dialing device corresponds to one water outlet temperature in the temperature range, and obviously, the more gears of the code dialing device, the more accurate the temperature setting.

In the above technical solution, each gear of the dial indicator is associated with at least one outlet water temperature.

In the technical scheme, different gears of the code dialing device correspond to one or more water outlet temperatures, and it can be understood that a plurality of temperature ranges, such as a high temperature range and a low temperature range, can be preset for the water heating device, and for different temperature ranges, the same gear corresponds to different water outlet temperatures. Thus, each gear may be associated with at least one outlet water temperature. In this way, the dialer can use fewer gears and cover a larger temperature range.

Wherein, because the dialler is to refining of different temperature interval temperature, can understand, even the fender position of dialler is the same, when adjusting different temperature intervals, can adjust to different temperatures.

Among the above-mentioned technical scheme, the hot water system includes: the wire controller is electrically connected with the controller, the wire controller can control the water outlet temperature of the heating body through the controller, and the priority of the wire controller is greater than that of the code dialing device.

In this technical scheme, through being connected wire controller and controller electricity, can control the controller, the leaving water temperature of control heating body. Wherein, if the hot water device is provided with the dialer and the wire controller at the same time, the control priority of the wire controller is higher than that of the dialer.

Generally, the dialer is installed at a location that is not frequently touched by users outdoors or indoors, and the outlet water temperature setting is adjusted by adjusting the gear. This is not very intuitive for the average user and is prone to error. Therefore, the dial is often used when the outlet water temperature is not adjusted frequently. And the drive-by-wire ware can install indoor to satisfy user's demand, specifically, the user can adjust outlet water temperature through the drive-by-wire ware at any time. The wire controller is relatively convenient for adjusting the temperature relative to the code dialing device.

Among the above-mentioned technical scheme, the hot water system includes: the display panel is electrically connected with the controller, can receive control instruction in order to control the leaving water temperature of heating the body through the controller, and the priority of display panel is greater than the priority of dialling the sign indicating number ware, and the priority of display panel is greater than the priority of line accuse ware.

In the technical scheme, the display panel is electrically connected with the controller and can be used for receiving a control instruction and controlling the controller according to the control instruction so as to adjust the water outlet temperature of the heating body. Relative to dialling a yard ware and drive-by-wire ware, the display panel can audio-visually show relevant information to the user, and is most audio-visually, relatively speaking, and it is most convenient to use. Therefore, if the hot water unit is equipped with a dialer, a line controller and a display panel, the display panel will have a higher priority than the dialer, the line controller and the display panel.

In actual use, the display panels have various forms, such as a traditional key and display screen mode and a more convenient touch screen mode, and can check related information such as the state of the water heater, the preset water outlet temperature and the like at any time while a user inputs an instruction.

In the technical scheme, the controller can be used for controlling the outlet water temperature according to the priority and the instruction of the display panel or the wire controller.

In the technical scheme, the priorities of the dialer, the line controller and the display panel are different, the priority of the display panel is the highest, and the priority of the dialer is the lowest. When two or more of the hot water apparatuses are installed at the same time, the controller determines the water temperature only at the temperature set by the apparatus having the highest priority.

For example, when the line controller and the dialer are installed in the equipment, the outlet water temperature is determined by the temperature set by the line controller, and the dialer does not work. When the equipment is simultaneously provided with the display panel, the line controller and the code dialing device, the outlet water temperature is determined by the display panel, and the line controller and the code dialing device do not work.

Due to the design, the situation that the control logic is disordered due to the fact that different devices jointly control the controller in the water heating device can be avoided.

Meanwhile, the priority of the controllers can also enable the equipment with low priority to immediately control after the equipment with high priority fails, thereby improving the working stability of the water heating device.

In the technical scheme, after the wire controller and the display panel are disconnected with the controller, if at least one dial switch is turned on, the controller controls water outlet according to the water outlet temperature corresponding to the gear of the dial indicator.

In the technical scheme, the priority of the wire controller and the display panel in the hot water device is higher than that of the dialer. Thus, if one of the two devices is installed in the hot water device, neither of the dials will contribute to the temperature setting.

Conversely, if the line controller or display panel is disconnected from the hot water unit, then the dialer is the only temperature control device in the hot water, and the dialer will then be active in the temperature setting of the controller. The dial switch is equivalent to setting a water outlet temperature value for the controller as long as one dial switch is turned on. The controller can take the temperature value corresponding to the code dialing device as the water outlet temperature.

Generally, the dialer is located in a location that is not frequently touched by the user, and the probability of failure is small. In this way, it can be ensured that the outlet water temperature of the water heater is in a controlled state under any condition.

In the technical scheme, when the water heating device is powered on, the controller is used for detecting the switch state of the dial switch of the dial indicator, when all the dial switches are closed, the water outlet temperature is controlled according to the line controller or the display panel, and when any one dial switch is turned on, the water outlet temperature is controlled according to the dial indicator.

In this technical scheme, when the hot water system circular telegram, because the state of dialling the sign indicating number can not change usually, consequently adopt the state of dialling the sign indicating number as the basis of hot water system temperature initial value, can guarantee the stability of hot water system temperature initial value that goes out. The hot water device can firstly detect the switch state of the switch of the code dialing device so as to obtain the set initial value of the water outlet temperature. If only one dial switch is turned on, the water heating device takes the temperature value corresponding to the dial switch as the initial value of the outlet water temperature. If all the dial switches are in the off state, the water heating device can set an initial value according to the display panel or the wire control device.

After the hot water device obtains the initial value of the outlet water temperature, the outlet water temperature is controlled according to the priority of the control device.

Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

Detailed Description

In order that the above objects, features and advantages of the embodiments of the present invention can be more clearly understood, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, embodiments of the present invention may be practiced in other ways than those described herein, and therefore the scope of the present application is not limited to the specific embodiments disclosed below.

Some embodiments according to the invention are described below with reference to fig. 1 to 4.

Example one

As shown in fig. 1, according to the technical solution of the present invention, there is provided a water heating apparatus 1: comprises a heating body 2 and a controller 206, wherein a water tank 202 and a heating device 204 are arranged in the heating body 2. The water tank 202 is used for storing water to be heated, the controller 206 can control the water outlet temperature of the heating body 2, and the controller 206 is electrically connected with the heating device 204. The dial 208 is electrically connected with the controller 206, and the controller 206 controls the outlet water temperature according to the gear of the dial 208.

The dialer 208 is a device having a plurality of dial switches 222, each of the dial switches 222 having both an on state and an off state. The different combinations of the plurality of dip switches 222 form a plurality of gears. These different gears may correspond to different values. Thus, the outlet temperature may be set using the dip switch 222. When the water heater is used, the controller 206 controls the water heater 1 according to the temperature set by the user according to the position of the dial switch 222 corresponding to the temperature to be set according to the convention, and finally the outlet water temperature is the temperature set by the user.

The dial switch 222 needs to be manually toggled by a user to change the state, and the operation is inconvenient. And is therefore typically used in situations where the state is not adjusted frequently. The dialer 208 is a mechanical structure and is not easily affected by the environment. Can be installed outdoors. For a water heater, the use of the dialer 208 may be sufficient if the outlet water temperature is not adjusted often.

Example two

As shown in fig. 2, according to the technical solution of the present invention, there is provided a water heating apparatus 1: comprises a heating body 2 and a controller 206, wherein a water tank 202 and a heating device 204 are arranged in the heating body 2. The water tank 202 is used for storing water to be heated, the controller 206 can control the water outlet temperature of the heating body 2, and the controller 206 is electrically connected with the heating device 204. The dial 208 is electrically connected with the controller 206, and the controller 206 controls the outlet water temperature according to the gear of the dial 208.

The heating device 204 in this embodiment comprises an auxiliary heater 210 and a burner 212. The auxiliary heater 210 employs a solar heater 216. The solar heater 216 heats the water and then feeds the water to the water tank 202. The water temperature sensor 214 senses the temperature of the incoming water to the tank 202.

The solar heater 216 does not need a user to provide energy for the heater, and relies on solar radiation to heat water, which is a very economical and environment-friendly heating mode. The water entering the water heating device 1 from the water pipe firstly enters the solar water heater and is heated by solar energy. The water is heated by the solar heater 216 and then sent to the water tank 202.

The temperature of the water flowing from the solar heater 216 into the water tank 202 is unstable due to the influence of the environment such as weather. Typically in winter, the heating effect of the solar heater 216 is much less than in summer. There was little heating effect on cloudy days.

The heating principle of the solar heater 216 is that sunlight is irradiated for a long time to continuously heat water. The solar heater 216 is heated for a relatively long time. In order to prevent bacteria from breeding in water and ensure the health of water for users, the scheme requires that the water inlet temperature of the solar heater 216 flowing into the water tank 202 must reach the first temperature to ensure that the bacteria can be killed. The first scheme in this scheme is set to 50 ℃.

Therefore, the water temperature sensor 214 is arranged in the scheme to detect the inlet water temperature. If the incoming water temperature is lower than the first temperature, the controller 206 may activate the burner 212 to increase the water temperature. Thus, even if the temperature of the inlet water from the solar heater 216 to the water tank 202 does not reach the first temperature, the heating device 204 can perform heating by the burner 212 to sterilize the water from the solar heater to the water tank 202 while ensuring the temperature of the outlet water.

The dial switch 222 needs to be manually toggled by a user to change the state, and the operation is inconvenient. And is therefore typically used in situations where the state is not adjusted frequently. The dialer 208 is a mechanical structure and is not easily affected by the environment. Can be installed outdoors. For a water heater, if the outlet water temperature is not adjusted frequently, the dial 208 can be used to meet the requirement.

EXAMPLE III

The heating device 204 in this embodiment comprises an auxiliary heater 210 and a burner 212. The auxiliary heater 210 employs a solar heater 216. The solar heater 216 heats the water and then feeds the water to the water tank 202. The water temperature sensor 214 detects the temperature of the water supplied to the water tank 202.

In practice, if there is some reason, the heating device 204 is not connected to the solar heater 216, but the cold water in the water pipe is directly introduced into the water tank 202 as inlet water. In this case, the problem of water sterilization can be eliminated, so that the step of heating the water to a temperature higher than the first temperature can be omitted, and energy can be saved.

In order to make the system distinguish whether the heating device 204 is equipped with the solar heater 216, it is set in the water heating device 1. If solar heater 216 is provided, the outlet water temperature should be higher than the first temperature, typically 50 ℃ to 70 ℃, which is a high temperature zone. If the solar heater 216 is not installed, the outlet water temperature may be lower than the first temperature, typically 35 ℃ to 50 ℃, which is a low temperature zone.

The dialer 208 subdivides the temperature zones based on their temperature ranges in the different temperature zones. In different temperature zones, the same dial 208 shifts, corresponding to different actual temperatures.

By means of the arrangement, the water heating device 1 can simultaneously deal with the situations that a solar water heater exists and no solar water heater exists under the condition that equipment is not added.

Example four

As shown in fig. 3, according to the technical solution of the present invention, there is provided a water heating apparatus 1: comprises a heating body 2 and a controller 206, wherein a water tank 202 and a heating device 204 are arranged in the heating body 2. The water tank 202 is used for storing water to be heated, the controller 206 can control the water outlet temperature of the heating body 2, and the controller 206 is electrically connected with the heating device 204. The dial 208 is electrically connected with the controller 206, and the controller 206 controls the outlet water temperature according to the gear of the dial 208.

The heating device 204 includes an auxiliary heater 210 and a burner 212. The auxiliary heater 210 employs a solar heater 216. The solar heater 216 heats the water and then feeds the water to the water tank 202. The water temperature sensor 214 detects the temperature of the water supplied to the water tank 202. In order to enable a user to adjust the outlet water temperature at any time, a wire controller 218 is added to set the temperature of the controller 206.

In this embodiment, the line controller 218 is installed indoors and is electrically connected to the controller 206. The user can directly operate the line controller 218 to adjust the setting of the outlet water temperature. Line director 218 has a higher priority than dialer 208. When the line controller 218 is installed in the water heating apparatus 1, the temperature setting of the dialer 208 is invalid, and the outlet water temperature is based on the line controller 218. When line controller 218 fails or is dialed, the priority of line controller 218 is automatically released within 60 seconds, and the water outlet temperature is set by the low priority dialer 208.

Line controller 218 is simpler and more convenient to operate than dialer 208.

EXAMPLE five

As shown in fig. 4, a display panel 220 is added to the water heating apparatus 1 based on the above embodiment. The display panel 220 is electrically connected to the controller 206. The display panel 220 can receive a control command from a user and control the outlet water temperature via the controller 206.

The display is relative to the dialer 208 and the wire controller 218, the display panel 220 adopts a touch panel, the outlet water temperature of the water heater can be directly adjusted on the touch panel, and the touch panel can synchronously display related information for a user, so that the display is most intuitive and relatively most convenient to use. When the hot water unit 1 is equipped with the dialer 208, the line controller 218, and the display panel 220, the display panel 220 has a higher priority than the dialer 208, the line controller 218, and the display panel 220. Dialer 208 and line controller 218 no longer set the outlet water temperature.

If the display panel 220 is unplugged during use, the priority of the display panel 220 will automatically be released within 10 seconds, instead of the priority being lower than the outlet water temperature set by the line controller 218 where the display panel 220 is higher than the dialer 208. If the line controller 218 is unplugged again, the priority of the line controller 218 is automatically released within 10 seconds, and the dialer 208 with the lowest priority is changed to set the outlet water temperature.

The temperature setting equipment with different priority levels not only ensures that the temperature setting of the outlet water is not disordered, but also ensures that other equipment can play a role even if a certain temperature setting equipment is cancelled or fails.

EXAMPLE six

As shown in fig. 4, according to the technical solution of the present invention, there is provided a water heating apparatus 1: comprises a heating body 2 and a controller 206, wherein a water tank 202 and a heating device 204 are arranged in the heating body 2. The water tank 202 is used for storing water to be heated, the controller 206 can control the water outlet temperature of the heating body 2, and the controller 206 is electrically connected with the heating device 204. The dial 208 is electrically connected with the controller 206, and the controller 206 controls the outlet water temperature according to the gear of the dial 208.

The heating device 204 includes an auxiliary heater 210 and a burner 212. The auxiliary heater 210 employs a solar heater 216. The solar heater 216 heats the water and then feeds the water to the water tank 202. The water temperature sensor 214 detects the temperature of the water supplied to the water tank 202. Display panel 220, line controller 218, and dialer 208 set the temperature of controller 206.

A display panel 220 and a line controller 218 are provided in the water heating apparatus 1. The display panel 220 is electrically connected to the controller 206. The display panel 220 can receive a control command from a user and control the outlet water temperature via the controller 206.

Display relative to dialer 208 and line controller 218, display panel 220 provides visual and most intuitive, and relatively convenient, display of relevant information to the user. When the hot water unit 1 is equipped with the dialer 208, the line controller 218, and the display panel 220, the display panel 220 has a higher priority than the dialer 208, the line controller 218, and the display panel 220. Dialer 208 and line controller 218 no longer set the outlet water temperature.

If the display panel 220 is unplugged during use, the priority of the display panel 220 will automatically be released within 10 seconds, instead of the priority being lower than the outlet water temperature set by the line controller 218 where the display panel 220 is higher than the dialer 208. If the line controller 218 is unplugged again, the priority of the line controller 218 is automatically released within 60 seconds, and the dialer 208 with the lowest priority is changed to set the outlet water temperature.

When the water heating device 1 is just powered on, the outlet water temperature needs to be set. At this time, whether the hot water device 1 is provided with the line controller 218 or the display panel 220, the hot water device 1 will first check the on-off state of the dial switch 222 of the dial 208. If the dial switch 222 is turned on, the water heating apparatus 1 will use the temperature value set by the dial 208 as the initial value. Only when the dial switch 222 is turned off, the temperature value memorized by the line controller 218 or the display panel 220 is used as the set outlet water temperature.

After the hot water apparatus 1 is powered on and started, the outlet water temperature set by the controller 206 is adjusted according to the priority of the display panel 220, the line controller 218 and the encoder.

According to the technical scheme of the invention, the outlet water temperature of the hot water device 1 can be set through the dial-up device 208, and the requirement of a use scene with lower temperature regulation demand frequency is met. Logic for the priority relationship of display panel 220, line controller 218 and dialer 208 is also presented to satisfy the compatibility requirements of various temperature regulating devices.
