Description

TECHNICAL FIELD The present invention relates to a heating machine, and more particularly to a heating machine that allows the start of heating operation and temperature setting to be remotely controlled using an operating terminal such as a remote control.

2. Description of the Related Art Hitherto, heaters have been known that include a heater main body and an operation terminal such as a remote control. The main body of the heater is provided with a main body operation section for starting and stopping the heating operation, setting the heating temperature, etc. The operating terminal is also provided with a terminal-side operating section for performing substantially the same operations as the main body of the heater. The heater main body includes a control section that controls the heating operation according to operations by the main body side operation section and the terminal side operation section.

Furthermore, in this type of heater, if the operating terminal is located a predetermined distance away from the main body of the heater, the heating temperature can be set using the operating terminal, but the operation to start heating operation is not accepted. (See Patent Document 1 below).

According to this, unless a user who wants to operate the operating terminal is near the heater main body, the operation of the heater main body cannot be started. Therefore, for example, if there are items that are not suitable for sudden temperature rises near the front of the hot air outlet of the heater body, or if there are children or pets, relatively high-temperature hot air will hit them. can be prevented.

JP2018-35986A

However, with the above-mentioned conventional devices, even if the user accurately understands the surrounding situation of the heating device before operating the operating terminal, the terminal is located a predetermined distance away from the heating device. Since heating operation cannot be started from the operating terminal, it is inconvenient to use.

Further, since a means for ascertaining that the operating terminal is located a predetermined distance away from the heater body is required, there is an inconvenience that the number of parts and the number of processing steps increase, resulting in an increase in cost.

Furthermore, if the heating operation does not start even after operating the control terminal, the user may not be able to understand the cause and may be confused, so a sound or display will be provided to indicate that the control terminal is located a predetermined distance from the heating unit. It is also necessary to notify the user of the problem, which also increases the number of parts and processing steps, resulting in an increase in cost.

In view of the above points, it is an object of the present invention to provide a heater that can prevent heating at excessively high temperatures when operated by an operation terminal, has a simple configuration, suppresses cost increase, and is easy to use. purpose.

In order to achieve such an object, the present invention includes a heating machine main body and an operation terminal for remotely controlling the heating machine main body, and the heating machine main body is configured to perform a first operation operation for starting a heating operation. a first heating temperature setting operation section for setting a heating temperature, and a control section for controlling heating operation, and the operation terminal includes a first heating temperature setting operation section for setting a heating temperature, and a first heating temperature setting operation section for controlling heating operation of the heating machine main body. a second heating temperature setting operation section for setting a heating temperature; In the machine, the first heating temperature setting operation section is capable of setting the heating temperature within a predetermined first temperature range, and the second heating temperature setting operation section is capable of setting the heating temperature within a predetermined first temperature range. It is characterized in that the temperature can be set within a predetermined second temperature range by setting the upper limit temperature lower than the range.

According to the present invention, the second temperature range that can be set by the second heating temperature setting operation section of the operation terminal is lower than the upper limit of the first temperature range that can be set by the first heating temperature setting operation section of the heater main body. Since the temperature is also low, heating at an excessively high temperature when operating the operating terminal can be prevented. Since the present invention has a configuration that limits the temperature range that can be set by the operating terminal, the increase in cost can be suppressed as a simple configuration, and when the user operates the operating terminal without being aware of it. Since heating at an excessively high temperature can be prevented, an easy-to-use heater can be provided.

Moreover, in the heater of the present invention, the first temperature range of the first heating temperature setting operation section is higher than at least a normal temperature setting range selected during normal use and an upper limit of the normal temperature setting range. The second temperature range of the second heating temperature setting operation section is configured by at least the normal temperature setting range, excluding the high temperature setting.

The normal temperature setting range is a heating temperature range in which many users feel comfortable, and is a range that includes setting temperatures that are selected relatively frequently in normal use. The set high temperature is a set temperature used to quickly warm up the room, and is higher than the upper limit temperature of the normal temperature setting range. Heating at a high temperature setting may have an adverse effect on articles that are not suitable for rapid temperature rises, and may cause discomfort to children and pets due to the heat.

If the user is near the heater main body, the user can check the surroundings of the heater main body, and therefore can quickly warm the room by operating the first heating temperature setting operation section and selecting a high temperature setting.

On the other hand, when the user operates the second heating temperature setting operation section of the operation terminal, the high temperature setting cannot be selected. Therefore, even if the user is located far away from the heater and cannot immediately check the area around the heater, it may have a negative effect on items that are not suitable for rapid temperature rises, or may cause harm to children. It is possible to prevent operation at high heating temperatures that may cause discomfort to pets.

FIG. 1 is a diagram showing a heater according to an embodiment of the present invention. The figure which shows typically the structure of the heating machine main body.

An embodiment of the present invention will be described based on the drawings. As shown in FIG. 1, the heating machine of this embodiment includes a heating machine main body 1 and a remote control 2 as an operating terminal for remotely controlling the heating machine main body 1.

As shown in FIG. 2, the heater main body 1 is placed on the floor in a space to be heated such as an indoor room of a house, and includes a gas burner 3 and a convection fan 4 that forcibly sends out air heated by the gas burner 3. , and a control device 5 (control unit) that controls heating operation.

A main body side operation panel 6, which will be described later, is provided on the upper surface of the heater main body 1. An air intake port 7 is formed on the back side of the heater body 1 to take in air sucked in by the operation of the convection fan 4 into the heater body 1. A room temperature sensor 8 is attached near the air intake port 7 to detect the room temperature.

Further, a hot air outlet 9 is formed at the lower front of the heater main body 1 to direct the air (warm air) sent out by the convection fan 4 forward. The hot air outlet 9 is provided with a louver 10 for determining the wind direction.

A portion of the air taken in from the air intake port 7 by the operation of the convection fan 4 is supplied to the gas burner 3 as combustion air. Fuel gas is supplied to the gas burner 3 from a gas supply path (not shown).

The combustion exhaust gas generated by the gas burner 3 is mixed with other air taken in from the air intake port 7, and is sent into the room from the hot air outlet 9 as warm air for heating.

Note that the amount of fuel gas supplied to the gas burner 3 is controlled by the control device 5 via a flow rate adjustment valve such as a gas proportional valve provided in a gas supply path (not shown). The amount of fuel gas supplied to the gas burner 3 is proportional to the combustion amount of the gas burner 3.

Further, the amount of combustion air supplied to the gas burner 3 can be increased or decreased depending on the rotation speed of the convection fan 4. The convection fan 4 is rotationally driven by an electric motor (not shown), and the rotation speed of the convection fan 4 is controlled by the control device 5 via the electric motor.

The control device 5 is composed of an electronic circuit unit including a CPU, RAM, ROM, an interface circuit, and the like. The control device 5 controls the combustion of the gas burner 3 and the operation of the convection fan 4 based on operations from the main body side operation panel 6.

As shown in FIG. 1, the main unit operation panel 6 includes a main unit operation switch 11 for starting and stopping the heating unit 1, a main unit up switch 12 for adjusting the heating temperature, and a main unit side up switch 12 for adjusting the heating temperature. A down switch 13 is provided.

Further, the main body side operation panel 6 is provided with a display section 14 . The display unit 14 displays various information such as the set heating temperature and the current room temperature.

In addition to this, the main body side operation panel 6 includes a plurality of switches for setting and changing the operating state of the heating machine main body 1 and setting a timer, but a description thereof will be omitted. The main body side up switch 12 and the main body side down switch 13 are used not only to adjust the heating temperature but also to change the timer time and the like.

The main body side operation switch 11 corresponds to the first operation operation section in the present invention, and the main body side up switch 12 and the main body side down switch 13 correspond to the first heating temperature setting operation section in the present invention.

As shown in FIG. 1, the remote control 2 is configured to be able to communicate with the heater main body 1 via wireless communication. In this embodiment, an infrared communication method is adopted as a communication method between the remote control 2 and the heater main body 1.

The remote control 2 includes a remote control side operation panel 15 including a plurality of switches. The remote control side operation panel 15 is mainly provided with a remote control side operation ON switch 16, a remote control side operation OFF switch 17, a remote control side up switch 18, and a remote control side down switch 19.

The remote control side operation ON switch 16 is pressed to start the operation of the heater main body 1, and the remote control side operation OFF switch 17 is pressed to stop the operation of the heater main body 1. The remote control side up switch 18 and the remote control side down switch 19 adjust the heating temperature.

The remote control side operation ON switch 16 corresponds to the second operation operation section in the present invention, and the remote control side up switch 18 and the remote control side down switch 19 correspond to the second heating temperature setting operation section in the present invention.

The control device 5 is electrically connected to the operating section 6 and also to an infrared receiving section 21 for receiving signals transmitted from the infrared transmitting section 20 of the remote controller 2 . The infrared receiving section 21 is exposed and disposed at the upper front surface of the heater main body 1.

Next, heating operation by the heater of this embodiment will be explained. When the user is near the heater main body 1, the user performs an operation to start heating operation using the main body operation switch 11 of the main body operation panel 6. Subsequently, the user operates to set a desired heating temperature using the main body side up switch 12 and the main body side down switch 13 as necessary.

When the heating temperature is set using the main body side up switch 12 or the main body side down switch 13 on the main body side operation panel 6, the control device 5 controls the combustion of the gas burner 3 with the combustion amount according to the set heating temperature. do.

At this time, the heating temperatures that can be selected by operating the main body side up switch 12 and main body side down switch 13 on the main body side operation panel 6 are each temperature within the normal temperature setting range and a low setting lower than the lower limit of the normal temperature setting range. temperature and a set high temperature higher than the upper limit of the normal temperature setting range.

Specifically, for example, the normal temperature setting range is "12°C to 26°C" in this embodiment, and the user presses the main body side up switch 12 or the main body side down switch 13 multiple times to set the temperature within this range. When the temperature is selected, the set heating temperature selected at that time is numerically displayed on the display section 14. When the set heating temperature is within the normal temperature setting range, the control device 5 controls the combustion amount of the gas burner 3 so that the room temperature reaches the temperature. Note that the normal temperature setting range is not limited to "12° C. to 26° C.", but is preferably a temperature range that is selected most frequently and provides high comfort for the user.

The set low temperature is "10°C" in this embodiment, and when the user selects this by pressing the down switch 13 on the main body side multiple times, "L" is displayed on the display section 14, and this becomes the lower limit set temperature. . The set low temperature is not to raise the room temperature but to maintain a sufficiently warm room temperature, and the control device 5 controls the gas burner 3 by keeping the combustion amount low. Note that the set low temperature is not limited to "10°C".

The set high temperature is "50°C" in this embodiment, and when the user presses the up switch 12 on the main body side multiple times to select this, "H" is displayed on the display section 14, and this becomes the upper limit set temperature. . The set high temperature is used to quickly warm up the room when the room is extremely cold, and the control device 5 controls the gas burner 3 at the maximum combustion amount. Note that the set high temperature is not limited to "50° C." since it is to continue the combustion operation with the gas burner 3 at the maximum combustion amount. Further, the control device 5 may have a control function that forcibly stops the heating operation when the room temperature reaches 35° C. or higher and the heating operation continues for 10 minutes, for example. According to this, an excessive rise in room temperature can be prevented.

When the control device 5 detects the operation of the main body side up switch 12 or the main body side down switch 13 on the main body side operation panel 6, the control device 5 selects the set low temperature, normal temperature setting range, and high temperature setting as the user's settable heating temperature range. Provided to.

On the other hand, when the user is located away from the heater main body 1, the user performs an operation to start the heating operation using the remote control side operation ON switch 16 of the remote control side operation panel 15 of the remote control 2. Subsequently, the user sets the desired heating temperature using the remote control up switch 18 and the remote control down switch 19 as necessary.

Even when the heating temperature is set using the remote control side up switch 18 or the remote control side down switch 19 on the remote control side operation panel 15, the control device 5 controls the combustion of the gas burner 3 with the combustion amount according to the set heating temperature. control.

At this time, each temperature within the normal temperature setting range and a set low temperature are prepared as heating temperatures that can be selected by operating the remote control side up switch 18 or remote control side down switch 19 on the remote control side operation panel 15. High temperature cannot be selected.

That is, when the user presses the main body side up switch 12 or the main body side down switch 13 multiple times to select any temperature within this temperature range, the display unit 14 displays the set heating temperature selected at that time as a numerical value. . The control device 5 controls the combustion amount of the gas burner 3 so that the heating temperature is within the set normal temperature setting range.

In this embodiment, since the normal temperature setting range is "12°C to 26°C", when the upper limit is reached by operating the remote control side up switch 18 of the remote control side operation panel 15, 26°C is selected. Therefore, a higher temperature cannot be selected.

The user can select a set low temperature by pressing the down switch 19 on the remote control side multiple times, similar to the operation on the main body side operation panel 6.

In addition, when the upper limit temperature of the normal temperature setting range is reached by operating the up switch 18 on the remote control side, the remote control 2 side may restrict so that a signal exceeding the upper limit temperature (here, 26° C.) is not output; When the control device 5 recognizes that the temperature is set according to the signal from the remote controller 2, it may control the combustion of the gas burner 3 so that the temperature does not exceed the upper limit temperature of the normal temperature setting range (here, 26° C.).

Further, the control device 5 stores the set temperature immediately before the previous heating operation was stopped, and the stored set temperature is used as the set temperature at the start of the next heating operation. Then, if the set high temperature (50°C in this embodiment) was selected immediately before the previous heating operation was stopped, the heating operation is started using the remote control side operation ON switch 16 of the remote control side operation panel 15. Then, the control device 5 forcibly sets the temperature to the maximum temperature in the normal temperature setting range (26° C. in this embodiment) and starts the heating operation.

As described above, unlike the operation to start operation or the heating temperature setting operation on the main unit side operation panel 6, when operating the remote control side operation panel 15, the set high temperature cannot be selected, and as a result, it is possible to inadvertently set a relatively high temperature. The warm air is not blown out from the hot air outlet 9 of the heater body 1.

As a result, if there are objects that are not suitable for sudden temperature rises, or if there are children or pets near the front of the hot air outlet 9 of the heater main body 1, relatively high temperature warm air will hit them. can be prevented. Moreover, it is only necessary to disable the setting high temperature from being selected when operating the remote control side operation panel 15, and there is no need to detect the distance between the heater body 1 and the remote control 2, for example, so the structure is simple but the cost increases. There are also extremely few. Furthermore, as long as the signal from the remote controller 2 (infrared rays in this embodiment) reaches the heater main body 1, heating operation can be smoothly started by operating the remote controller 2, making it easy to use.

In addition, in this embodiment, a hot air heater equipped with the gas burner 3 as a heat source is shown, but the present invention is not limited to this. The invention can be adopted and the same effects as this embodiment can be obtained.

Moreover, in this embodiment, although the communication between the remote control 2 and the heater main body 1 is performed by an infrared communication method, the communication is not limited to this, and Bluetooth (registered trademark) or Wi-Fi method may be used.

Further, in this embodiment, an example is shown in which the remote control 2 is used as the operating terminal, but the operating terminal is not limited to this, and a smart fan or a tablet terminal equipped with a remote control function by application software may be adopted. .
