  However, in the remote control device, a certain display icon is continuously displayed according to the achievement level. Therefore, there is a problem that the user who sees the display icon gets bored with the picture and change of the display icon as the usage period of the remote control elapses, and the interest in executing the energy saving operation is reduced.

  It is an object of the present invention to provide a remote control device that can eliminate such problems and maintain the user's interest in performing energy saving operation.

In order to achieve this object, the remote control device of the present invention consumes target energy that is a target value of energy to be consumed by the water heater during the first predetermined period and is actually consumed by the water heater during the first predetermined period. The achievement level calculation means for comparing the energy consumption and calculating the achievement level of the consumption energy relative to the target energy, and using the achievement level set in advance according to the achievement level calculated by the achievement level calculation means A remote control device comprising: a display selection unit that selects a display icon to be displayed from among achievement level display patterns having a plurality of display icons to be recognized by a person; and a display unit that displays the display icon selected by the display selection unit. The display selection means includes a plurality of types of achievement level display patterns having different display forms. The display form differs from the achievement level display pattern according to changes in physical quantities of external factors including the passage of the second predetermined period or at least the temperature, humidity, and sunshine time detected by the detection means. A configuration for selecting the achievement level display pattern of the type is provided .

  In the remote control device of the present invention, the achievement level display selected according to the passage of the second predetermined period or the physical quantity detected by the detecting means, for example, the physical quantity of an external factor such as temperature, humidity, sunshine duration, etc. Another type of achievement level display pattern having a different display form is selected instead of the pattern, and a display icon corresponding to the achievement level is displayed on the display unit from the selected achievement level display patterns.

  Therefore, according to the remote control device of the present invention, as a result of the achievement level display pattern being changed to a different type, the display icon displayed on the display unit is automatically changed without being operated by the user. The user's interest in performing energy-saving operation can be maintained.

According to a first aspect of the remote control device of the present invention, the achievement level calculation means is adapted to match a preset correction value determined by the passage of the second predetermined period or the physical quantity and a user's energy saving driving skill. A correction achievement level obtained by correcting the achievement level with a correction value that increases with the lapse of a period of time, and the display selection means determines the achievement level according to the correction achievement level calculated by the achievement level calculation means. and selects the icon to be displayed from among the display pattern.

  A user's skill for realizing energy-saving operation usually increases with the passage of time. On the other hand, the motivation for realizing the energy saving operation of the user is usually lowered with the passage of time.

  In addition, energy consumption in a water heater tends to be influenced by physical quantities of external factors such as temperature, humidity, and sunshine duration.

  Therefore, when the user tries to maintain a predetermined achievement level, there are cases where it is easy and difficult to execute the energy saving operation that satisfies the achievement level.

  In this case, for example, when the execution of the energy saving operation is too easy, the user may lose interest in executing the energy saving operation because the user loses a sense of achievement for the execution of the energy saving operation. On the other hand, for example, when the execution of the energy saving operation is too difficult, the user may give up the execution of the energy saving operation and the interest in the execution of the energy saving operation may be reduced.

  Therefore, the remote control device having the above-described configuration sets in advance a correction value determined by the passage of the second predetermined period or the physical quantity, corrects the achievement level with the correction value, and then adjusts the correction achievement level after correction. A display icon to be displayed is selected from the achievement level display patterns.

As a result, the remote control device comprising the structure, that it allows adjusting the assessment of energy saving operation by the user, it is possible to maintain the interest for the execution of the energy saving operation of the user. Furthermore, the achievement level calculation means can calculate a corrected achievement level obtained by correcting the achievement level with a correction value that increases with the passage of time so as to match the increase in the user's energy-saving driving skill.

Next, according to a second aspect of the present invention, the achievement level calculation means is adapted to match the advance of the second predetermined period set in advance or the correction value determined by the physical quantity and the increase in the energy-saving driving skill of the user. A corrected target energy is calculated by correcting the target energy with a correction value that increases with the passage of time, and the corrected target energy is compared with the consumed energy, and the correction of the consumed energy with respect to the corrected target energy is achieved. level is calculated, and the display selecting means, in accordance with the correction achieved level calculated by the achieved level calculating means, and selects the icon to be displayed from among the achieved level display pattern.

  In addition to correcting the achievement level itself, the correction value may correct the target energy, or may correct the consumed energy.

As a result, the remote control device comprising the structure, that it allows adjusting the evaluation against the energy-saving operation by the user, it is possible to maintain the interest for the execution of the energy saving operation of the user. Furthermore, the achievement level calculation means can calculate a corrected target energy obtained by correcting the target energy with a correction value that increases with the passage of time so as to match the increase in the energy-saving driving skill of the user.

  In the remote control device of the present invention, the display selection unit has a hidden achievement level display pattern that is different in display form from the plurality of types of achievement level display patterns, and the achievement level meets a predetermined achievement condition. The hidden achievement level display pattern may be selected instead of the achievement level display pattern.

  In the remote control device having the above configuration, the display icon included in the hidden display pattern can be displayed only when the achievement level meets a predetermined achievement condition. Therefore, the user has the goal of displaying the display icon, and in order to obtain a sense of accomplishment that clears the goal, the user can aim for energy-saving operation where the achievement level meets a predetermined achievement condition.

  Each eco-mark pattern corresponds to each column of the table shown in FIGS. 4A, 4C, and 4E, and a plurality of eco-mark icons that have a common expression form are collected to form one eco-mark pattern. A mark pattern is formed and set in advance in the display selection means 34.

  In addition, when the variable eco-mark pattern 120 is selected, the display selection unit 34 selects a predetermined variable eco-mark from a plurality of variable eco-mark patterns 120 according to the passage of a period (month) or the change in the physical quantity. A process of selecting the mark pattern 120 can be performed (second selection).

  The variable eco mark pattern 120 corresponds to each column of the table shown in FIG. 4C and is configured by a plurality of types having different display forms. In addition, as shown in FIG. 4C, the variable eco-mark pattern 120 is preset with the variable eco-mark pattern 120 corresponding to a predetermined period, and the month to which the date and time acquired from the time measuring means 35 belongs.

  Next, the consumption energy calculation means 32 of the remote controller 30 acquires the consumption energy A (FIG. 5 / STEP 110).

  Then, the achievement level calculation means 33 of the remote controller 30 calculates the achievement level C (FIG. 5 / STEP 120) on the condition that the consumed energy A has been acquired (FIG. 5 / STEP 110... YES).

  Next, the display selection unit 34 of the remote controller 30 determines whether or not the variable eco-mark pattern 120 is selected (first selection) (FIG. 5 / STEP 130).

  First, the case where the variable eco-mark pattern 120 is not selected, that is, the case where the normal fixed eco-mark pattern 110 is selected will be described (FIG. 5 / STEP 130... NO).

  When the fixed eco-mark pattern 110 is selected, the display selection unit 34 of the remote controller 30 selects a specific fixed eco-mark icon 111 from the fixed eco-mark pattern 110 and displays it in the eco-mark display area 100. It is displayed (FIG. 5 / STEP 140).

  Specifically, when the achievement level C is 98%, for example, the display selection unit 34 selects the threshold region 112 (third row from the top of the table of FIG. 4A) among the plurality of threshold regions 112 ( 105> C ≧ 95), the fixed eco-mark icon 111 corresponding to the threshold area is selected and displayed in the eco-mark display area 100 as shown in FIG.

  Next, the case where the variable eco-mark pattern 120 is selected will be described (FIG. 5 / STEP 130... YES).

  When the variable eco-mark pattern 120 is selected, the achievement level calculation means 33 of the remote controller 30 acquires numerical information of the month to which the current date belongs from the time measurement means 35 (FIG. 5 / STEP 150).

  Next, the achievement level calculation means 33 calculates a corrected achievement level C ′ obtained by multiplying the achievement level C by a correction value set in advance according to the numerical value information of the month (FIG. 5 / STEP 160).

  Next, the display selection means 34 selects a specific variable eco-mark pattern 120 from among the plurality of variable eco-mark patterns 120 (second selection), and selects a specific variable from the selected variable eco-mark pattern 120. The eco-mark icon 121 is selected (third selection), and the selected variable eco-mark icon 121 is displayed in the eco-mark display area 100 (FIG. 5 / STEP 170).

  Specifically, first, as shown in FIG. 4C, the display selection unit 34 recognizes the numerical value information of the month to which the date and time acquired from the time measuring unit 35 from among the plurality of variable eco-mark patterns 120, For example, if the numerical information is July, since July belongs to the month from June to August, the representation form of the tree in the second column of the table corresponding to June to August is used. The variable eco-mark pattern 120 is selected (second selection). When the correction achievement level C ′ calculated by the achievement level calculation means 33 is, for example, 92%, the correction achievement level C ′ is the threshold value in the fourth row from the top of the table of FIG. After determining that it belongs to the region 122 (95> C ≧ 90), the variable eco-mark icon 121 corresponding to the threshold region 122 is selected (third selection), and as shown in FIG. Displayed in the eco-mark display area 100.

  First, on the condition that the display selection means 34 becomes 10:00 once a day (FIG. 6 / STEP 200), whether the correction achievement level C ′ belongs to a predetermined threshold region among a plurality of threshold regions, for example, Then, it is determined whether or not the correction achievement level C ′ is less than 90% (FIG. 6 / STEP 210).

  When the correction achievement level C ′ is less than 90% (FIG. 6 / STEP 210... YES), the display selection means 34 sets 1 to the counter variable i (FIG. 6 / STEP 220). Then, the display selection means 34 repeatedly executes the loop of STEP 200 to STEP 230 while incrementing i in STEP 220 until it is confirmed that the counter variable becomes 4 or more (FIG. 6 / STEP 230).

  When the counter variable is 4 or more (FIG. 6 / STEP 230... YES), the display selection unit 34 selects the hidden eco-mark pattern 130 instead of the variable eco-mark pattern 120 (second selection).

  Then, the display selection means 34 selects a specific hidden eco-mark icon 131 from the selected hidden eco-mark pattern 130 (third selection) and displays it in the eco-mark display area 100 (FIG. 5 / STEP 240). .

  Specifically, the display selection unit 34, when the correction achievement level C ′ is 107%, for example, among the plurality of threshold areas 132, the threshold area 132 in the second row from the top of the table of FIG. After determining that it belongs to (110> C ≧ 105), the hidden eco-mark icon 131 corresponding to the threshold region is selected, and the third selected hidden eco-mark is displayed as shown in FIG. An icon 131 is displayed in the eco mark display area 100.
