本发明涉及远距离操作热水器主体的家庭用热水器。The present invention relates to a domestic water heater for remotely operating a water heater body.
以往，例如在煤气的热水器中，作为远距离操作器的有线通信式遥控，是在热水器主体接入电源时在热水器主体、遥控器之间进行通信信息(初始设定温度、热水器主体的状态)的收发的，并遥控显示热水器主体的状态。Conventionally, for example, in a gas water heater, the wired communication remote control as a remote operator communicates information between the water heater body and the remote control (initial setting temperature, state of the water heater body) when the water heater body is powered on. The sending and receiving, and the remote control shows the status of the main body of the water heater.
且停电复位时，热水器主体将通信信息(来自各遥控器的设定温度、时钟数据等)发送给遥控器，使热水器主体的状态与遥控器显示保持一致。And when the power failure resets, the main body of the water heater sends communication information (setting temperature, clock data, etc. from each remote controller) to the remote controller, so that the state of the main body of the water heater is consistent with the display of the remote controller.
但是，在无线式遥控情况下，由于各电源独立设置，即使无线式遥控器的电源处于接通状态，而热水器主体的电源也未必接入，因热水器主体的电源未接入而不能接收电波，所以存在无线式遥控器发射无用电波的问题。However, in the case of wireless remote control, since each power supply is set independently, even if the power supply of the wireless remote control is turned on, the power supply of the water heater body may not be connected, and the electric wave cannot be received because the power supply of the water heater body is not connected. Therefore, there is a problem that the wireless remote controller emits unnecessary radio waves.
另外，对于许多同型号热水器集中设置的集体住宅，因热水器产生的状态变化多，当从停电恢复供电时会全部发送通信信息(设定温度、最后的存贮、时钟复位等)，从而瞬间发生过密电波的冲突。因此存在因各热水器间无线电波的干扰而不能正常收发的问题。In addition, for collective houses where many water heaters of the same type are installed in a centralized manner, there are many state changes caused by the water heaters. When the power supply is restored from a power outage, all communication information (set temperature, last storage, clock reset, etc.) will be sent, resulting in instantaneous Conflict of over-dense radio waves. Therefore, there is a problem that normal transmission and reception cannot be performed due to interference of radio waves between the water heaters.
本发明为了解决上述问题，其第一目的在于，热水器主体的电源未接入时无线式遥控器不会发送无用的电波。In order to solve the above-mentioned problems, the first object of the present invention is to prevent the wireless remote controller from sending unnecessary radio waves when the water heater body is not powered on.
本发明的第二目的在于，当热水器主体的商用电源由停电至复电时，使热水器主体发送给无线式遥控器的信号数据简单化，通过减少集中设置的热水器间的电波冲突，热水器主体与无线式遥控器间就能容易进行无线通信。The second object of the present invention is to simplify the signal data sent by the water heater body to the wireless remote controller when the commercial power supply of the water heater body is restored from a power outage, and reduce the electric wave conflict between the water heaters that are centrally installed. Wireless communication between wireless remote controllers can be easily performed.
本发明第三目的在于，当热水器主体的商用电源从停电至复电时通过将各热水器主体向无线式遥控器发送信息的时间稍稍随机地错开，使集中设置的许多热水器间的多个信号的电波冲突减少，从而能进行热水器主体与无线式遥控器间的无线通信。The third object of the present invention is to stagger the time at which each water heater main body sends information to the wireless remote controller slightly randomly when the commercial power supply of the water heater main body is from a power outage to a power recovery, so that the communication between multiple signals among a large number of water heaters that are collectively installed Radio wave collisions are reduced, enabling wireless communication between the water heater body and the wireless remote controller.
为了实现上述目的，本发明第1实施例的无线式遥控热水器，它具有热水器主体和遥控操作该热水器主体、进行运行指示的无线式遥控器，其特征在于，上述热水器主体具有：检测电源接入的电源接入检测装置；接收电源接入检测装置的电源接入检测信号并将电源接入的信号和运行信息进行无线通信的热水器主体收发装置，所述无线式遥控器具有：根据热水器主体收发装置来的信号判定热水器主体电源是否接入的电源接入判定装置；显示热水器主体的运行信息和热水器主体的电源未接入信息的显示装置；与热水器主体进行无线通信的收发装置。In order to achieve the above object, the wireless remote control water heater according to the first embodiment of the present invention has a water heater main body and a wireless remote controller for remotely operating the water heater main body and performing operation instructions. It is characterized in that the above water heater main body has: The power access detection device; the water heater main transceiver device that receives the power access detection signal of the power access detection device and wirelessly communicates the power access signal and operation information, and the wireless remote controller has: The signal from the device determines whether the power supply of the water heater body is connected to the power supply judging device; the display device displays the operation information of the water heater body and the information that the power supply of the water heater body is not connected; the transceiver device for wireless communication with the water heater body.
本发明第2实施例是，其中热水器主体具有检测商用电源从停电至复电的复电检测装置。In the second embodiment of the present invention, the main body of the water heater has a power recovery detection device for detecting the recovery of the commercial power supply from a power failure.
本发明第3实施例是，其中当电源接入检测装置检测到从停电至复电时，热水器主体收发装置在其它热水器主体与其它热水器的无线式遥控器不同的发送时间进行发送。In the third embodiment of the present invention, when the power access detection device detects that the power is turned off and then the power is restored, the water heater body transceiver device transmits at different transmission times from the other water heater bodies and the wireless remote controllers of other water heaters.
按照上述第1实施例，本发明的无线式遥控器在热水器主体的电源接入时能给出区别于热水器主体的运行信息的特定显示，因不给热水器主体发送信号而不会输出无用电波(能有效利用电波)。According to the above-mentioned first embodiment, the wireless remote controller of the present invention can provide a specific display different from the operation information of the water heater body when the power supply of the water heater body is turned on, and will not output useless radio waves because no signal is sent to the water heater body ( can effectively use radio waves).
在第2实施例中，热水器主体检测到由停电至恢复供电时，由于向无线式遥控器发送上述特定显示的信息而能发送比发送任何运行信息更简单的通信数据，另外在第3实施例中，尤其是在许多同类型热水器集中设置的集体住宅情况下，通过使各热水器主体发送的时刻稍稍错开而能避免多个信号电波的冲突，使热水器主体的运行状态不会与无线式遥控器的显示不一致。In the second embodiment, when the main body of the water heater detects that the power supply is restored from a power failure, since the above-mentioned specifically displayed information is sent to the wireless remote controller, communication data that is simpler than any operation information can be sent. In addition, in the third embodiment In particular, in the case of collective housing where many water heaters of the same type are concentrated, the conflict of multiple signal waves can be avoided by slightly staggering the sending time of each water heater body, so that the running state of the water heater body will not be inconsistent with the wireless remote control. display is inconsistent.

热水器主体9的构成为：检测商用电源是否接入或从停电是否恢复供电的停电检测装置6；向无线式遥控器5指示热水器主体9的非通电状态的特定显示的“显示OFF”指示装置7；具有前述识别信号与无线式遥控器5进行无线通信的热水器主体收发装置8；和将向无线式遥控器5的发送时间稍稍错开的定时装置10。而遥控器收发装置3与热水器主体收发装置8相互判读对方的无线信号的识别信号，只与组合相符的对方进行无线通信。The water heater main body 9 is composed of: a power failure detection device 6 for detecting whether the commercial power supply is connected or whether the power supply is restored from a power failure; a "display OFF" indicating device 7 for a specific display indicating the non-energized state of the water heater main body 9 to the wireless remote controller 5 ; the water heater main transceiver device 8 having the identification signal wirelessly communicated with the wireless remote controller 5 ; The remote control transceiver device 3 and the water heater main body transceiver device 8 mutually interpret the identification signal of each other's wireless signal, and only carry out wireless communication with the counterpart that matches the combination.
下面说明第一实施例的动作。无线式遥控器5借助电源接入判定装置1根据来自热水器主体的无线信号的有无判定热水器主体9的电源是否接入。若电源未接入时由“显示OFF”请求装置2在无线式遥控器5的显示装置4中显示“显示OFF”。用户通过显示装置4显示的“显示OFF”了解到热水器主体9的电源未接入，这种显示能区别于热水器主体9的运行中或运行停止状态的显示。同时，遥控器收发装置3在由电源接入判定装置1判断为热水器主体9的电源未接入时不向热水器主体9发送无用的信号。Next, the operation of the first embodiment will be described. The wireless remote controller 5 judges whether the power supply of the water heater main body 9 is connected according to the presence or absence of the wireless signal from the water heater main body by means of the power input determination device 1 . If the power supply is not connected, the "display OFF" request device 2 displays "display OFF" in the display device 4 of the wireless remote controller 5. The user knows that the power supply of the water heater main body 9 is not connected through the "display OFF" displayed on the display device 4, and this display can be distinguished from the display of the water heater main body 9 in running or stopped state. At the same time, the remote control transceiver device 3 does not send unnecessary signals to the water heater main body 9 when it is judged by the power access determination device 1 that the water heater main body 9 is not powered on.
下面说明第2实施例的动作，当图1的热水器主体9在商用电源停电后再通电时，由停电恢复检测装置6判定为商用电源从停电恢复供电。在检测到这种从停电恢复供电之后，热水器主体收发装置8将来自“显示OFF”指示装置7的信号发送给无线遥控器5。无线式遥控器5的遥控收发装置3接收“显示OFF”指示信号，显示装置4根据来自“显示OFF”请求装置2的信号显示“显示OFF”。The action of the second embodiment will be described below. When the water heater main body 9 of FIG. 1 is powered on again after a commercial power failure, it is determined by the power failure recovery detection device 6 that the commercial power supply resumes power supply from a power failure. After detecting such restoration of power supply from a power outage, the water heater main body transceiving means 8 transmits a signal from the “display OFF” indicating means 7 to the wireless remote controller 5 . The remote control transceiver unit 3 of the wireless remote controller 5 receives the “display OFF” instruction signal, and the display unit 4 displays “display OFF” according to the signal from the “display OFF” request unit 2 .
在第三实施例中，在上述热水器主体9中设有定时装置10。该定时装置将各热水器主体的定时器动作时间设定成分别带随机的时间，这样，在集体住宅等集中设置多个热水器的情况下，热水器主体9从停电至复电时，由热水器主体9的热水器主体收发装置8发送来自“显示OFF”指示装置7的信号的时间对各热水器是各不一致的，因此，在集体住宅中多个热水器主体9一起从停电至复电的情况下，从各热水器主体9发送的无线电波是离散的，无线式遥控器5能减少电波的重复，同时能尽量避免了区别其它热水器系统的判定作业。In the third embodiment, a timer device 10 is provided in the above-mentioned water heater body 9 . This timing device sets the timer action time of each water heater main body to the time with random respectively, like this, under the situation that a plurality of water heaters are arranged collectively etc. collectively, when water heater main body 9 is from power outage to power recovery, by water heater main body 9 The time when the water heater main body transceiver device 8 sends the signal from the "display OFF" indicating device 7 is inconsistent for each water heater. The radio wave sent by the water heater main body 9 is discrete, and the wireless remote controller 5 can reduce the repetition of the radio wave, and simultaneously avoid the judgment operation of distinguishing other water heater systems as much as possible.
由上述说明可见，本发明权利要求1的无线式遥控热水器，在热水器主体未通电源时，用户用显示装置能区分热水器主体未接电源，无线式遥控器不发送无意义的信号，所以能有效地使用电波，并能防止发送无效的电波。It can be seen from the above description that in the wireless remote control water heater of claim 1 of the present invention, when the main body of the water heater is not powered on, the user can use the display device to distinguish that the main body of the water heater is not connected to the power supply, and the wireless remote control does not send meaningless signals, so it can effectively Use radio waves more efficiently and prevent invalid radio waves from being sent.
权利要求2的无线式遥控热水器，热水器主体从停电至复电时，发送特定信号，与电源接入时一样具有显示，所以，用户也能知道停电，具有与上述情况相同的效果。The wireless remote control water heater of claim 2, when the main body of the water heater sends a specific signal from power failure to power recovery, has the same display as when the power is turned on, so the user can also know the power failure, and has the same effect as the above case.
再有，在权利要求3中，给每个热水器装置设有随机的定时装置，通过将发送的时间稍稍错开，当从停电至复电时，即使在多个装置集中设置的情况下也具有能避免多个电波冲突的效果。Furthermore, in claim 3, each water heater device is provided with a random timing device, and by slightly staggering the sending time, when the power is restored from a power outage, even if a plurality of devices are collectively installed, it can Avoid the effect of multiple radio waves conflicting.
