Description

  The present invention relates to an air conditioner having an ion generation function. More specifically, the present invention relates to a technique for displaying the amount of ions generated in a user-friendly manner in an air conditioner having an ion generation function.

An air conditioner having a function of generating positive ions and negative ions has been developed in order to remove floating bacteria in the room and adjust the ion balance in the room.
Since negative ions and positive ions are not visible and often odorless, it is difficult for the user to recognize whether the air conditioner generates ions. In addition, it is difficult for the user to recognize the type of ions generated by the air conditioner and the amount of ions generated. Against the backdrop of increasing interest in the influence of negative ions and positive ions on the indoor environment, there is a desire for users of air conditioners with an ion generation function to know the state of ion generation. In order to respond to such a desire, a technology has been developed that displays in an easy-to-understand manner the state of ion generation in a device having an ion generation function.

  For example, Patent Document 1 discloses a configuration in which the generation of negative ions is displayed by lighting a lamp, and the lamp luminance and the amount of light are changed according to the amount of negative ions generated. Patent Document 1 also discloses a configuration that uses an indicator display that changes the number of lamps that are turned on according to the amount of negative ions generated.

  Patent Document 2 discloses a configuration in which the amount of negative ions or positive ions detected by an ion sensor is displayed in correspondence with the same level of natural conditions. In the technique of Patent Document 2, the same level of natural conditions corresponding to the detected ion level is selectively selected by characters such as “waterfall / mountain stream”, “Shinshu forest”, “general residential area”, and “urban area”. indicate. Patent Document 2 also discloses a configuration in which the numerical value of the amount of negative ions or positive ions generated is digitally displayed.

  According to the techniques of Patent Document 1 and Patent Document 2, if the user knows in advance the display rules for the ion generation status in the air conditioner, the ion generation status is easily recognized from the displayed contents. can do. Therefore, when a limited user, such as a general household, uses the air conditioner on a daily basis, the user should be familiar with the display rules on the air conditioner and easily recognize the ion generation status. Will be able to.

However, for users who do not know the display rules for the ion generation status in the air conditioner, the conventional display technology has not always been easy to understand. For example, in a service that provides a place where guests can relax comfortably, such as a coffee shop, a hotel, or a rest area, if an air conditioner with an ion generation function is installed as part of the service, many of the visitors You will see the air conditioner for the first time. In such a situation, a visitor who is a user does not know in advance the display rules for the ion generation status in the air conditioner. Therefore, for example, in the display technique disclosed in Patent Document 1, the user immediately determines what the lamp display means, what the lamp brightness and brightness, and the number of lit lamps mean. Can not be recognized.
Further, as in Patent Document 2, even when the natural conditions at the same level as the generated ions are selectively displayed by characters, or when the amount of generated ions is digitally displayed numerically, the user can display the displayed characters and It was difficult to understand intuitively by reading the numbers and understanding the meaning. It was not necessarily a display technology that was easy for users to understand.

  The present invention has been made in view of the above problems, and in an air conditioner with an ion generation function, even if a user who does not know the display rules for the ion generation status, the generation of ions generated from the air conditioner Provide a technology that can easily recognize the situation.

The present invention is embodied as an air conditioner with an ion generation function. The air conditioner with an ion generation function includes ion generation means and display means. The ion generating means generates both positive ions represented by H ⁺ (H ₂ O) _m (m is a natural number) and negative ions represented by O ₂ ⁻ (H ₂ O) _n (n is a natural number). positive and negative ion mode to, provided with a negative ion mode to generate only the negative ion is operable in the selected mode from among the positive and negative ion mode and negative ion mode. The display means includes a positive ion mark stylized the positive ions, the the negative ions negative ions marks stylized, place a plurality of the positive ions marks and a plurality of negative ions mark in two dimensions A display area that can be displayed is provided, and the number of positive ion marks and negative ion marks displayed in the display area is changed according to the mode in which the ion generating means is operating. The display means displays substantially the same number of positive ion marks and negative ion marks in the display area when the ion generating means is operating in the positive / negative ion mode. The display means displays the negative ion mark in the display area and does not display the positive ion mark in the display area when the ion generating means is operating in the negative ion mode.

  In this air conditioner, the operation mode of the ion generating means is expressed by the number of positive ion marks and negative ion marks displayed in the display area. Since the positive ion mark and the negative ion mark are respectively designed positive ions and negative ions, the user of the air conditioner can quickly recognize what each mark means. In addition, the user of the air conditioner visually recognizes the distribution of positive ion marks and negative ion marks that are two-dimensionally arranged in the display area, and whether ions are actively being supplied into the room. Or it can grasp | ascertain intuitively whether it is performed gently.

  Further, in this air conditioner, when the ion generating means generates both positive ions and negative ions, substantially the same number of positive ion marks and negative ion marks are displayed in the display area, and the ion generating means is negative. When only ions are generated, only the negative ion mark is displayed in the display area, and the positive ion mark is not displayed. Therefore, the user of the air conditioner visually recognizes the distribution of the positive ion marks and the negative ion marks arranged two-dimensionally in the display area, and accurately determines the type of ions generated by the ion generating means. I can grasp it.

  According to this air conditioner with ion generation function, even a user who does not know the display rules for the ion generation status can intuitively grasp the ion generation status from the contents displayed in the display area. Can do. The generation state of ions can be easily recognized.

  In the air conditioner with an ion generation function, it is preferable that the positive ion mark and the negative ion mark have a round shape, and the coloring of the positive ion mark and the negative ion mark is different from each other.

In general, positive ions and negative ions are often designed as spherical particles. Therefore, by setting the positive ion mark and negative ion mark displayed in the display area in a round shape, the user of the air conditioner designs the positive ion and the negative ion respectively for the positive ion mark and the negative ion mark. In particular, it is possible to quickly conceive, and from the content displayed in the display area, it is possible to quickly grasp the generation state of ions.
In addition, by making the coloring of the positive ion mark and the negative ion mark different from each other, the user of the air conditioner can more clearly recognize the difference between the positive ion mark and the negative ion mark and The type can be quickly grasped.

  In the above-described air conditioner with an ion generating function, the ion generating means includes a blowing means for sending the generated ions to the outside of the air conditioner, and the blowing means can adjust the strength of the blowing capacity. It is preferable that the display means increase or decrease the maximum number of the positive ion marks and the negative ion marks or the maximum number displayed at a time in the display region for each of the positive ion marks and the negative ion marks according to the blowing capacity of the blowing means.

As the number of positive ion marks and negative ion marks displayed at one time in the display area is increased, the display area is filled with positive ion marks and negative ion marks. In this way, when the display area is filled with the positive ion mark or the negative ion mark, the user who visually recognizes the display area can be reminded of a scene in which the room is filled with positive ions or negative ions. .
Therefore, when the blowing means has a strong blowing capacity and the ions generated by the ion generating means reach every corner of the room, the user can increase the maximum number of ion marks displayed at one time in the display area. Can be recognized accurately.

  According to the air conditioner with an ion generation function of the present invention, even a user who does not know the display rules for the ion generation state can easily recognize the ion generation state in the air conditioner.

The main features of the embodiments described below are listed first.
(Embodiment 1) The ion generating means generates positive ions and negative ions by applying a high voltage from an AC power source to the inner electrode and the outer electrode that are arranged across the insulator on the cylinder and discharging them.

An embodiment of a gas fan heater with an ion generation function embodying the present invention will be described in detail with reference to the drawings.
As shown in FIGS. 1 and 2, the gas fan heater 100 of this embodiment includes a main body case 102, a heating unit 104 and an ion generation unit 106 housed in the main body case 102. The ion generation unit 106 is accommodated in the main body case 102 above the heating unit 104.

  As shown in FIG. 2, the main body case 102 forms an outer frame of the gas fan heater 100. A common air inlet 110 for taking in air used for heating and air used for generating ions is formed on the back surface of the main body case 102, an ion air outlet 108 is formed on the upper surface, and a hot air outlet 112 is formed on the front surface. Has been.

  A common air filter 114 is detachably provided in the common intake port 110 so as to cover the entire surface thereof. The common air filter 114 is for removing dust in the room, and is formed from a fine mesh made of resin. Air sucked from the common inlet 110 through the common air filter 114 is sucked into the heating unit 104 and the ion generation unit 106.

The heating unit 104 includes a combustion case 118 having a gas burner 116 therein, and a hot-air fan 120 disposed below the combustion case 118. The combustion case 118 and the hot air fan 120 are arranged behind the partition plate 122 formed in the main body case 102.
When the hot air fan 120 is rotated and the gas burner 116 is ignited, the combustion secondary air sucked from the common intake port 110 and sucked from the combustion secondary air intake port 124, and a combustion primary air intake port (not shown). The fuel gas is combusted by the primary air for combustion sucked from. Combustion gas generated by the combustion is discharged from the upper part of the gas burner 116 through the upper part of the combustion case 118.
During combustion, air is continuously sucked from the common intake port 110 by the rotation of the hot air fan 120. As a result, the combustion gas discharged from the upper part of the combustion case 118 and the air sucked from the common intake port 110 are mixed between the partition plate 122 and the combustion case 118 to become mixed air adjusted to an appropriate temperature. .
Further, the air sucked from the common intake port 110 by the rotation of the hot air fan 120 flows downward between the main body case 102 and the partition plate 122 to cool the main body case 102, and finally the partition plate 122. The air is sucked into the heating unit 104 from the lower gap and further mixed with the mixed air coming from the upstream side. The mixed air thus mixed becomes warm air having an appropriate temperature for heating.
The hot air is guided to the hot air outlet 112 by the rotation of the hot air fan 120 and blown out into the room.

  The ion generation unit 106 includes a small sirocco fan 128 disposed behind the partition plate 126 and an ion generator 130 disposed above the sirocco fan 128. A dust collection filter 132 is disposed behind the sirocco fan 128 and the ion generator 130. The rear of the ion generation unit 106 is open, and air can be sucked from the common intake port 110.

  The dust collection filter 132 is provided so as to cover the entire rear surface of the ion generation unit 106. The dust collection filter 132 collects fine particulate dust that has not been completely removed by the common air filter 114, odor sources, cigarette smoke, and the like, and cleans the air passing therethrough.

The details of the ion generator 130 are shown in FIGS. The ion generator 130 generates both positive ions and negative ions by applying a high voltage from the AC power supply 140 to the inner electrode 136 and the outer electrode 138 disposed with the cylindrical insulator 134 interposed therebetween. By applying an alternating high voltage between the inner electrode 136 and the outer electrode 138, an ionization phenomenon due to discharge or the like occurs in the atmosphere, and positive ions H ⁺ (H ₂ O) _m (m is a natural number) and negative ions O ₂ ⁻ (H ₂ O) _n (n is a natural number) is stably generated.

The sirocco fan 128 is rotated by driving a small motor 128a built in the center. The sirocco fan 128 sucks air from the common intake port 110 through the dust collection filter 132 and passes the air cleaned by the dust collection filter 132 and the ions generated by the ion generator 130 through the ion air outlet 108. Release into the room.
Positive ions and negative ions released into the room surround floating bacteria floating in the air. Positive ions and negative ions chemically react on the surface of the floating bacteria to generate hydrogen peroxide (H ₂ O ₂ ) or hydroxyl radical (OH), which are active species. Thereby, floating bacteria are destroyed and sterilized by the action of decomposing active species. Therefore, the bacteria floating in the indoor air can be sterilized and removed efficiently.

  The ion generator 130 can control the generation ratio of positive ions and negative ions. When an alternating voltage is applied as it is in the ion generator 130, positive ions and negative ions can be generated with substantially the same generation amount. Further, by applying only the negative side of the AC voltage and not applying the positive side, only negative ions can be generated.

As shown in FIG. 1, an operation panel 142 that allows the user to operate the heating unit 104 and the ion generation unit 106 is provided in front of the upper surface of the main body case 102. As shown well in FIG. 5, the operation panel 142 includes a liquid crystal display 144, a heating operation lamp 146 for notifying that the heating operation is being performed, and a filter lamp 148 for notifying that the air filter needs to be cleaned. Various operation switches such as a heating operation switch 150, an ion operation switch 152, and a temperature setting switch 154 are provided.
As shown in FIG. 1, an ion operation lamp 156 that notifies the state of the ion generation operation is provided above the front surface of the main body case 102. The ion operation lamp 156 includes a blue light emitting element and a green light emitting element, and emits blue or green light depending on the state of the ion generation operation.

  In operation panel 142 in FIG. 5, operation of heating operation switch 150 instructs the start and stop of heating operation performed by heating unit 104. By operating the ion operation switch 152, the start and stop of the ion generation operation performed by the ion generation unit 106 are instructed, and the ion generation operation mode desired by the user is set. The ion generation operation mode will be described later. The room temperature desired by the user is set by operating the temperature setting switch 154. The gas fan heater 100 with an ion generation function according to the present embodiment can perform the heating operation and the ion generation operation independently of each other, or can perform the heating operation and the ion generation operation at the same time.

  As shown in FIG. 2, a controller 158 that controls the operation of the heating unit 104 and the ion generation unit 106 is provided inside the main body case 102. The controller 158 controls the operation of the heating unit 104 and the ion generation unit 106 and also controls display on the user on the operation panel 142 and the like.

As shown in FIG. 6, the controller 158 includes a heating unit control unit 160, an ion generation unit control unit 162, and a display control unit 164.
The heating unit control means 160 controls the ignition / extinguishing operation of the gas burner 116, the amount of fuel gas supplied to the gas burner 116, and the rotational speed of the hot air fan 120. When instructed to start the heating operation by the heating operation switch 150, the heating unit control means 160 rotates the hot air fan 120, ignites the gas burner 116, and starts the heating operation. The heating unit control means 160 supplies the fuel gas to the gas burner 116 based on the current room temperature detected by the room temperature thermistor 166 provided on the back surface of the main body case 102 and the set room temperature set by the temperature setting switch 154. And the rotational speed of the hot air fan 120 is controlled. When the heating operation switch 150 instructs the heating unit control means 160 to stop the heating operation, the heating unit control means 160 extinguishes the gas burner 116, stops the rotation of the hot air fan 120, and stops the heating operation.

The ion generation unit control means 162 controls the type of ions generated in the ion generator 130 and the rotational speed of the sirocco fan 128. The ion generation operation mode controlled by the ion generation unit control means 162 is selected from the three modes of “ positive / negative ion strong operation”, “ positive / negative ion weak operation”, and “ negative ion operation” by operating the ion operation switch 152. Is set. When the ion operation switch 152 is pressed while the operation of the ion generation unit 106 is stopped, the mode is set to “ positive and negative ion strong operation”. When the ion operation switch 152 is pressed while “ positive / negative ion strong operation” is set, the mode is set to “ positive / negative ion weak operation”. When the ion operation switch 152 is pressed while “ positive and negative ion weak operation” is set, the mode is set to “ negative ion operation”. If the ion operation switch 152 is pressed while “ negative ion operation” is set, the ion generation unit 106 stops operation.

When the mode is set to “ positive and negative ion strong operation”, the ion generation unit control unit 162 causes the ion generator 130 to generate positive ions and negative ions with substantially the same generation amount, and drives the sirocco fan 128 at high speed. . As a result, both positive ions and negative ions are generated with substantially the same generation amount, and are released into the room with a large air volume.
When the mode is set to “ positive and negative ion weak operation”, the ion generation unit control unit 162 causes the ion generator 130 to generate positive ions and negative ions with substantially the same generation amount, and drives the sirocco fan 128 at a low speed. . As a result, both positive ions and negative ions are generated with substantially the same generation amount, and released into the room with a small air volume.
When the mode is set to “ negative ion operation”, the ion generation unit controller 162 generates only negative ions in the ion generator 130 and drives the sirocco fan 128. As a result, only negative ions are generated and released into the room.

  The display control unit 164 controls the display of the liquid crystal display unit 144 and lighting of the heating operation lamp 146, the ion operation lamp 156, and the filter lamp 148. As shown in FIG. 5, the set room temperature of heating and the current room temperature are digitally displayed near the center of the liquid crystal display unit 144. The left end portion of the liquid crystal display unit 144 is an ion display region 168, and an ion generation operation mode set in the ion generation unit control unit 162 is displayed.

  A display change mode in the ion display region 168 of the liquid crystal display unit 144 will be described with reference to FIGS.

FIG. 7 shows a display change mode in the ion display area 168 when the ion generation operation mode is “ positive and negative ion strong operation”. The display control means 164 switches the display in the ion display area 168 at predetermined time intervals in the order of (a), (b), (c), (d), and (e) in FIG. Are switched again in the order of (a), (b), (c), (d), and (e) in FIG. The display control means 164 repeats such display switching until the ion generation operation mode is changed.

  In the display state of FIG. 7A, negative ion marks 170 expressing negative ions and positive ion marks 172 expressing positive ions are alternately formed at the bottom of the ion display region 168 so as to form a row in the horizontal direction. Placed in. The negative ion mark 170 and the positive ion mark 172 are designed as circles having the same diameter and different internal colors.

  When the display state shown in FIG. 7A is switched to the display state shown in FIG. 7B, the negative ion mark 170 and the positive ion mark 172 displayed in FIG. A row in which 170 and positive ion marks 172 are alternately arranged is newly arranged. In the column added in the display state of FIG. 7B, the diameters of the negative ion mark 170 and the positive ion mark 172 are larger than the diameters of the negative ion mark 170 and the positive ion mark 172 in the lower column. The spacing is also slightly increased. Further, the numbers of the negative ion marks 170 and the positive ion marks 172 in the added row are equal to the numbers in the lower row, and the order in the row is also the same. Further, the center position in the left-right direction of the added row is aligned so as to be equal to the center position in the left-right direction of the lower row.

When the display state of FIG. 7B is changed to the display state of FIG. 7C, negative ions are further above the two rows of the negative ion mark 170 and the positive ion mark 172 displayed in FIG. 7B. A row in which the marks 170 and the positive ion marks 172 are alternately arranged is newly arranged.
In the column added in the display state of FIG. 7C, the diameter of the mark is larger than the diameter of the mark in the lower column, and the interval between the marks is slightly widened. Further, the number of negative ion marks 170 and positive ion marks 172 in the added column is equal to the number of each in the lower column, and the order in the column also matches. Further, the center position in the left-right direction of the row is aligned with the center position in the left-right direction of the lower row.
Further, in the state of FIG. 7C, a minus sign and a plus sign are respectively given to the inside of the negative ion mark 170 and the positive ion mark 172 in the added column.

  In FIG. 7D and FIG. 7E as well, a row of negative ion marks 170 and positive ion marks 172 is sequentially added in the same manner. The negative ion mark 170 and the positive ion mark 172 added in FIGS. 7D and 7E are given a minus sign or a plus sign in the same manner as those added in FIG. 7C. Yes.

When the display in the ion display area 168 is changed as shown in FIG. 7, a negative ion mark 170 and a positive ion mark 172 are generated at the lower part of the ion display area 168, and these generated marks are moved upward in the ion display area 168. And the ion display region 168 is filled with the negative ion mark 170 and the positive ion mark 172. Further, since the diameter of the mark increases toward the upper side of the ion display region 168, the effect of the perspective method gives the impression that these marks gradually approach the near side.
By changing the display in the ion display region 168 as described above, positive ions and negative ions generated by the ion generation unit 106 are discharged upward from the ion air outlet 108 and the released ions are used. It can be reminiscent of the user as it spreads to the user side and eventually fills the room with positive and negative ions. In addition, the negative ion mark 170 and the positive ion mark 172 are expressed by circles having different internal colors, and a minus sign or a plus sign is assigned to the inside of each mark. It can be intuitively recognized that the negative ions and the positive ions are generated to the same extent.

  By performing such display in the ion display area 168, even a user who does not know the display rules for the amount of ions generated, both positive ions and negative ions are generated, and positive ions It can be intuitively recognized that the negative ions are generated at substantially the same rate, and that the blowing capability of the ion generation operation is strong and the generated ions are distributed throughout the room.

FIG. 8 shows how the display changes in the ion display area 168 when the ion generation operation mode is “ positive / negative ion weak operation”. The display control means 164 switches the display in the ion display area 168 at predetermined time intervals in the order of (a), (b), and (c) in FIG. 8 and then switches to (c) in FIG. Switching is performed in the order of (a), (b), and (c) in FIG. The display control means 164 repeats such display switching until the ion generation operation mode is changed.
The display of the negative ion mark 170 and the positive ion mark 172 in (a), (b) and (c) of FIG. 8 is the same as the display of these marks in (a), (b) and (c) of FIG. Therefore, the overlapping description is omitted here.

When the display in the ion display area 168 is changed as shown in FIG. 8, the scene where the positive ions and negative ions generated by the ion generation unit 106 spread in the room is used as in the case shown in FIG. Can be reminiscent of a person.
Unlike the case shown in FIG. 7, when the display is changed as shown in FIG. 8, the entire ion display region 168 is not completely filled with the negative ion mark 170 and the positive ion mark 172. The lower half of the display area 168 is filled with the negative ion mark 170 and the positive ion mark 172. Accordingly, the user can intuitively recognize that the blowing ability of the ion generation operation is weak and the generated ions are not distributed throughout the room.

FIG. 9 shows how the display changes in the ion display area 168 when the ion generation operation mode is “ negative ion operation”. The display control means 164 switches the display in the ion display region 168 at predetermined time intervals in the order of (a), (b), (c), and (d) in FIG. 9 and switches to (d) in FIG. Thereafter, switching is again performed in the order of (a), (b), (c), and (d) in FIG. The display control means 164 repeats such display switching until the ion generation operation mode is changed and the operation of the ion generation unit 106 is stopped.

As shown in (a), (b), (c) and (d) of FIG. 9, when the ion generation operation mode is set to “ negative ion operation”, the ion display region 168 includes The positive ion mark 172 is not displayed and only the negative ion mark 170 is displayed. The display of the negative ion mark 170 in (a), (b), (c) and (d) of FIG. 9 is the positive ion mark 172 in (a), (b), (c) and (d) of FIG. Since this is the same as the case where only the negative ion mark 170 is displayed without displaying, redundant description is omitted here.

When the display in the ion display area 168 is changed as shown in FIG. 9, the user is reminded of the scene in which ions generated by the ion generation unit 106 spread into the room, as in FIGS. be able to.
In the case of FIG. 9, since only the negative ion mark 170 is displayed in the ion display area 168 and the positive ion mark 172 is not displayed, the user generates only negative ions, and positive ions are generated. It can be intuitively recognized that it is not.

  According to the gas fan heater 100 of the present embodiment, even a user who does not know the display rules for the amount of generated ions in advance can perform the ion generation operation from the content displayed in the ion display area 168. Aspect can be intuitively recognized. The user's desire to know the generation state of ions from the gas fan heater 100 can be satisfied.

Various display modes of the ion display region 168 other than those described above are conceivable. For example, when the ion generation amount in the ion generator 130 is variable, the maximum number of positive ion marks and negative ion marks displayed in the ion display region 168 may be increased or decreased according to the ion generation amount. . Alternatively, the ratio between the number of positive ion marks and the number of negative ion marks displayed may be changed according to the generation ratio of each ion.
The display switching speed in the ion display area 168 may be increased or decreased according to the rotation speed of the sirocco fan, or may be increased or decreased according to the amount of ions generated.
