Description

[Technical Field]

[0001] The present disclosure relates to an air conditioner that removes bacteria, fungi, viruses, odors, and the like from the air using electrolyzed water obtained by passing electricity through water. [Background technology]

[0002] A conventional air conditioner comprises a main body case, a water storage container, a water supply means for automatically supplying water to maintain a constant water level in the water storage container, and a means for detecting the presence or absence of liquid in the water storage container. Providing two detection means for the water storage container and the water storage container would increase the size of the device, so two detection means are realized with one detection means (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-183981 Summary of the Invention [Problem to be solved by the invention]

[0004] In conventional water storage containers and systems for detecting the presence or absence of liquid in the container, a float unit with a built-in magnet that floats depending on the water level in the container is installed inside the container, and a detector element that can detect the magnetic field of the magnet is installed on the main body case. Because the float with a built-in magnet that floats depending on the water level is installed rotatably inside the container, this creates an uneven shape on the container, which makes it difficult to maintain.

[0005] Therefore, the present invention aims to solve the above-mentioned conventional problems and to provide a water storage container and a means for detecting the presence or absence of liquid in the water storage container without using a float with a built-in magnet, in order to minimize unevenness and make the water storage container easy to clean. [Means for solving the problem]

[0006] In order to achieve this object, the space conditioning device according to the present invention comprises: a main body case having an air intake port and an air outlet; a water storage container that is detachably provided in a hollow portion of the main body case, the hollow portion being partially surrounded by a partition wall, and that stores water; a filter disposed so that its lower end is immersed in the water in the water storage container; a blower that blows air drawn in through the air intake port through the filter to the air outlet; an electrostatic sensor provided on the isolation wall and configured to detect electrostatic capacitance; a control unit that stores the capacitance detected by the electrostatic sensor, the cavity portion extends horizontally inward from one side surface of the main body case, the electrostatic sensor is provided on the isolation wall so as to face the water in the water storage container via a side surface of the water storage container; The capacitance detected by the electrostatic sensor when the water storage container is attached to the hollow portion is: the capacitance is greater than the capacitance detected by the electrostatic sensor when the water storage container is not attached to the hollow portion, The capacitance detected by the electrostatic sensor when the water storage container containing water at a predetermined level is attached to the hollow portion is: The electrostatic sensor detects the water when the water storage container is attached without storing water in the hollow portion. The capacitance is larger than the The control unit detects the attachment of the water storage container to the hollow portion and the presence of water at the specified water level based on the change in capacitance detected by the electrostatic sensor, thereby achieving the intended purpose. [Effects of the Invention]

[0007] According to the present invention, it is possible to obtain the effect of reducing the uneven shape of the water storage container, making it easier to clean the water storage container. [Brief explanation of the drawings]

[0009] (Embodiment 1) A first embodiment of the present disclosure will be described with reference to the drawings.

Fig. 3 is a view showing the cross-sectional configuration of the air conditioning apparatus 1 viewed from the right side as you face the front.

[0011] In the following, the vertical direction when the air conditioning apparatus is installed (hereinafter also referred to as the "installed state") as shown in Fig. 1 may be referred to as the up-down direction, and the horizontal direction as the left-right direction. In the following, in the installed state, the side of the air conditioning apparatus on which panel 9 is provided will be referred to as the "right side," and the side facing the right side of the air conditioning apparatus will be referred to as the "left side." When viewed from the right side of the air conditioning apparatus, the left side is the "front," and when viewed from the right side of the air conditioning apparatus, the right side is the "rear."

[0012] The following describes the detailed configuration of the air conditioner 1. As shown in Figures 1 to 3, the air conditioner 1 of this embodiment includes a substantially box-shaped main body case 2, a blower 3, an air conditioning unit 4, a control unit 5, and an operation unit 6.

[0013] The main body case 2 has a generally vertically long box shape, and is provided with an air intake 7, an air outlet 8, and a panel 9.

[0014] The air intakes 7 are provided on the left and right side surfaces of the main body case 2.

[0015] The air outlet 8 is provided on the rear side of the top surface of the main body case 2. An operation unit 6 is provided on the front side of the top surface of the main body case 2.

[0016] An openable panel 9 is provided on one side surface of the main body case 2. When the panel 9 is opened, the air conditioning unit 4 is located inside the main body case 2.

[0017] 3, an air passage 11 (indicated by an arrow) that connects the air intake 7 and the air outlet 8 is provided inside the main body case 2. In the air passage 11, in order from the air intake 7, the air conditioning unit 4 (including a water storage container 19 and a filter portion, which will be described later), the blower 3, and the air outlet 8 are provided.

[0018] The blower 3 is provided in the upper part of the main body case 2, and includes a motor section 12, a fan section 13 rotated by the motor section 12, and a scroll-shaped casing section 14 surrounding these.

[0019] The motor unit 12 is a single-shaft motor, and a rotation shaft 15 of the motor unit 12 extends from the front side to the rear side of the main body case 2.

[0020] The fan unit 13 is a sirocco fan, and is fixed to the tip of a rotary shaft 15 that extends horizontally from the motor unit 12.

[0021] The casing unit 14 is provided with an outlet 16 and an inlet (not shown). The outlet 16 is provided on the top surface of the main body case 2 of the casing unit 14. The inlet is provided on the back surface of the main body case 2 of the casing unit 14. When the fan unit 13 is rotated by the motor unit 12, air outside the casing unit 14 flows into the casing unit 14 through the inlet, and is blown out of the casing unit 14 through the outlet 16.

[0022] Fig. 4 is a perspective view of the air conditioning apparatus 1 according to the first embodiment of the present disclosure, with the panel 9 open and the tank member 20 removed, and the air conditioning apparatus 1 viewed from diagonally above the front side. Fig. 5 is a perspective view of the air conditioning apparatus 1 according to the first embodiment of the present disclosure, with the panel 9 open and the water storage container 19 removed, and the air conditioning apparatus 1 viewed from diagonally above the front side.

[0023] As shown in Figures 4 and 5, the air conditioning unit 4 is provided in a hollow portion 10. The hollow portion 10 is a hole recessed from one side surface (right side surface) of the main body case 2 to the other side surface (left side surface) of the main body case 2. The air conditioning unit 4 can be removed from inside the hollow portion 10 to the outside of the main body case 2. The air conditioning unit 4 includes a water storage container 19, a tank member 20, and an air-liquid contact portion 21.

[0024] The water storage container 19 is made of resin, has a bowl shape with an opening on the top, and is structured to store water. One example of the material is ABS resin. The water storage container 19 is arranged at the bottom of the main body case 2, and is arranged so that it can be attached and detached by opening the panel 9 and sliding horizontally from the cavity 10. The water storage container 19 stores water supplied from the tank member 20.

[0025] Fig. 6 is an exploded perspective view of the tank member 20 according to the first embodiment of the present disclosure. Fig. 7 is a diagram showing a cross-sectional configuration of the tank member 20 according to the first embodiment of the present disclosure. Fig. 8 is a diagram showing a cross-sectional configuration of the water storage container 19 according to the first embodiment of the present disclosure. Fig. 9 is a cross-sectional configuration of the water storage container 19 according to the first embodiment of the present disclosure with the tank member 20 and the gas-liquid contact portion 21 attached thereto. FIG.

[0026] 6 to 9, the tank member 20 is installed at the bottom inside the main body case 2 and has a structure that allows it to be attached to and detached from the water storage container 19. The bottom surface of the water storage container 19 is provided with a tank holding portion 23 that protrudes upward.

[0027] The tank member 20 is attached to the tank holder 23 provided on the bottom surface of the water storage container 19. The tank member 20 has a tank 24 for storing water, an opening 24a provided on the bottom surface of the tank 24 that connects the inside of the tank 24 to the outside of the tank 24, and a lid 25 that covers the opening 24a.

[0028] The center of lid 25 is provided with hole 25b that communicates in the vertical direction, valve 26 that opens and closes hole 25b, and cylindrical tube portion 25a that surrounds hole 25b, has a central axis that extends in the vertical direction, and protrudes downward from lid 25. Hole 25b is disposed in the center when viewed in the direction of the central axis of tube portion 25a.

[0029] In the above configuration, when the tank member 20 is attached to the tank holding portion 23 of the water storage container 19 with the opening 24a of the tank 24 facing downward, the valve portion 26 is opened by the tank holding portion 23. In other words, when the tank member 20 is filled with water and attached to the tank holding portion 23, the valve portion 26 is moved upward by the tank holding portion 23, and the hole 25b of the lid 25 is opened. When the hole 25b of the lid 25 is opened, water in the tank 24 is supplied to the water storage container 19 through the hole 25b of the lid 25, and water accumulates in the water storage container 19.

[0030] When the water level in water storage container 19 rises and reaches the upper end of notch 25c at the lower end of tubular portion 25a of lid 25, hole 25b in tank member 20 is sealed with water, and water supply stops. Water remains inside tank member 20, and whenever the water level in water storage container 19 drops, water from inside the tank is supplied to water storage container 19. In other words, the water level in water storage container 19 is kept constant.

[0031] FIG. 10 is a perspective view of the water storage container 19 according to the first embodiment of the present disclosure with the gas-liquid contact portion 21 attached thereto.

[0032] 8 and 10, the gas-liquid contact portion 21 is a member that brings the water stored in the water storage container 19 into contact with the indoor air drawn into the main body case 2 by the blower 3. The gas-liquid contact portion 21 has a filter 27, a filter frame 28, and a drive unit 29.

[0033] The filter 27 is cylindrical and has holes around its circumference that allow air to pass through. The filter 27 is attached to a filter frame 28 so that one end of the filter 27 is immersed in the water in the water storage container 19.

[0034] The filter frame 28 is rotatably supported by a bearing portion 30 provided in the water storage container 19. The filter 27 and the filter frame 28 are configured to be rotated by a drive portion 29.

[0035] Indoor air drawn into the main body case 2 through the air intake 7 by the blower 3 is blown to the filter 27, the lower end of which is immersed in the water stored in the water storage container 19. The air blown to the filter 27 comes into contact with the water held in the filter 27, becoming humid air, which is then blown from the air outlet 8 into the room outside the main body case 2.

[0036] The control unit 5 controls the drive unit 29 of the gas-liquid contact portion 21 and the motor unit 12 of the blower 3. Specifically, the control unit 5 controls the operation of the drive unit 29 of the gas-liquid contact portion 21, the rotation speed of the fan unit 13 of the blower 3, etc. in response to the operation of the operation unit 6.

[0037] When fan unit 13 is rotated by motor unit 12 of blower 3, air is sent to air passage 11. As fan unit 13 rotates, outside air that has entered main body case 2 through air intake 7 passes through filter 27, blower 3, and air outlet 8, and is then blown out of main body case 2. By sending air to filter 27, which is immersed in water in water storage container 19, air conditioning device 1 vaporizes the moisture held by filter 27, thereby humidifying the air.

[0038] Fig. 11 is a perspective view of the air conditioning apparatus 1 according to the first embodiment of the present disclosure, showing the air conditioning apparatus 1 viewed from diagonally above the side with the panel 9 open and the tank member 20 removed. Fig. 12 is a diagram showing the cross-sectional configuration of the water storage container and electrostatic sensor as viewed from the right side of the main body case according to the first embodiment of the present disclosure. Fig. 13 is a block diagram showing the configuration of the air conditioning apparatus according to the first embodiment of the present disclosure.

[0039] As shown in Figures 3, 11, 12, and 13, cavity 10, which is a hole extending horizontally from one side (right side) of main body case 2 toward the inside of main body case 2, is partially surrounded by a partition wall 39 inside the main body case. A water storage container for storing water is detachably mounted horizontally inside cavity 10, which is partially surrounded by partition wall 39. A capacitance-type electrostatic sensor 40 that detects capacitance is mounted on partition wall 39. Main body case 2 is equipped with a control unit 5 that stores the capacitance detected by electrostatic sensor 40 and can attach water storage container 19 to cavity 10 and detect a predetermined water level in water storage container 19 based on changes in the capacitance detected by electrostatic sensor 40.

[0040] The partition wall 39 is made up of surfaces provided on the front, back, and left sides of the water storage container 19 when viewed from the front of the air conditioning apparatus 1. The partition wall 39 is made of resin, one example of which is ABS resin. The partition wall 39 is configured to surround at least a portion of the rear side, left side, and front side of the main body case 2 in the water storage container 19.

[0041] FIG. 12 is a diagram showing the cross-sectional configuration of the electrostatic sensor and its vicinity as viewed from the right side as facing the front of the air conditioner. The electrostatic sensor 40 detects electrostatic capacitance. One example of an electrostatic sensor 40 is a sensor that can be used to detect the presence and position of an object without touching it by detecting static electricity generated when an object is charged and converting it into an electrical signal. The electrostatic sensor 40 has a pair of electrodes, and electrostatic capacitance exists between the electrodes. The electrostatic capacitance varies depending on the distance between the electrostatic sensor 40 and the water. The electrostatic capacitance detected by the electrostatic sensor 40 decreases as the distance between the electrostatic sensor 40 and the water increases. The electrostatic sensor 40 is installed on the side of the partition wall 39 that is perpendicular to the water surface, facing the water in the water storage container 19 through the side of the water storage container 19. Here, the water storage container 19 and the partition wall 39 are configured such that the capacitance detected by the electrostatic sensor 40 when the water storage container 19 is attached to the hollow portion 10 is greater than the capacitance detected by the electrostatic sensor 40 when the water storage container 19 is not attached to the hollow portion 10, and the capacitance detected by the electrostatic sensor 40 when the water storage container 19 containing water at a predetermined level is attached to the hollow portion 10 is greater than the capacitance detected by the electrostatic sensor 40 when the water storage container 19 without water is attached to the hollow portion 10.

[0042] Specifically, when the water storage container 19 without water is attached to the cavity 10, the electrostatic sensor 40 detects the capacitance of the water storage container 19 that faces the electrostatic sensor 40. When the water storage container 19 is not attached to the cavity 10, the electrostatic sensor 40 detects the capacitance of the isolation wall 39 that faces the electrostatic sensor 40. Since the water storage container 19 and the isolation wall 39 are made of resin, there is not much difference in the capacitance between the water storage container 19 and the isolation wall 39. Since the distance to the water container 19 is shorter than the distance between the electrostatic sensor 40 and the isolation wall 39, the capacitance detected by the electrostatic sensor 40 when the water storage container 19 is attached to the hollow portion 10 is greater than the capacitance detected by the electrostatic sensor 40 when the water storage container 19 is not attached to the hollow portion 10.

[0043] Furthermore, when the water storage container 19 containing no water is attached to the cavity 10, the electrostatic sensor 40 detects the capacitance of the water storage container 19 facing the electrostatic sensor 40. When the water storage container 19 containing water at a predetermined level is attached to the cavity 10, the electrostatic sensor 40 detects the capacitance of the water storage container 19 facing the electrostatic sensor 40 and the capacitance of the water in the water storage container 19 facing the electrostatic sensor 40. Because the water storage container 19 is made of resin, the capacitance of the water in the water storage container 19 is greater than the capacitance of the water storage container 19. The capacitance detected by the electrostatic sensor 40 when the water storage container 19 containing water at a predetermined level is attached to the cavity 10 is greater than the capacitance detected by the electrostatic sensor 40 when the water storage container 19 containing no water is attached to the cavity 10.

[0044] This allows the control unit 5 to detect the attachment of the water storage container 19 to the cavity 10 and the presence of a predetermined level of water in the water storage container 19 based on the change in capacitance detected by the electrostatic sensor 40. When the control unit 5 detects the attachment of the water storage container 19 and the presence of a predetermined level of water in the water storage container 19 using the electrostatic sensor 40, it controls the operation of the drive unit 29 of the gas-liquid contact part 21 and the rotation speed of the fan unit 13 of the blower 3, etc., in accordance with the operation of the operation unit 6.

[0045] The electrostatic sensor 40 is also provided on the outer surface of the partition wall 39. Specifically, the electrostatic sensor 40 is provided facing the water storage container 19 across the partition wall 39 provided behind the water storage container 19 when viewed from the front of the air conditioning apparatus 1. The partition wall 39 provided at the rear also spatially separates the electrostatic sensor 40 from the cavity 10. This prevents the user from touching the electrostatic sensor 40, ensuring safety and preventing breakdowns and deterioration of the electrostatic sensor 40 and misalignment of the installation position.

[0046] Furthermore, the minimum distance between the portion of the partition wall 39 where the electrostatic sensor 40 is provided and the side surface of the water storage container 19 is smaller than the thickness of the side surface of the water storage container 19. Specifically, the water storage container 19 is detachable, and to enable detachment, there is a gap between the water storage container 19 and the partition wall 39 provided behind the water storage container 19 when viewed from the front of the air conditioning apparatus 1, and this gap is not uniform due to inclination, etc. The minimum distance of this gap is smaller than the thickness of the side surface of the water storage container 19 facing the electrostatic sensor 40. The thickness of the side surface of the water storage container 19 is, for example, 1.0 mm to 3.0 mm. This allows the electrostatic sensor 40 to be closer to the liquid in the water storage container 19, enabling changes in capacitance to be detected with high sensitivity.

[0047] Furthermore, the minimum distance between the portion of the partition wall 39 where the electrostatic sensor 40 is provided and the side surface of the water storage container 19 is smaller than the thickness of the portion of the partition wall 39 where the electrostatic sensor 40 is provided. Specifically, the thickness of the portion of the partition wall 39 where the electrostatic sensor 40 is provided is, for example, 0.5 mm to 3.0 mm. This allows the electrostatic sensor 40 to be closer to the liquid in the water storage container 19, enabling changes in capacitance to be detected with high sensitivity.

[0048] Furthermore, the thickness of the partition wall 39 is smallest at the portion where the electrostatic sensor 40 is provided. Specifically, the partition wall 39 has a certain thickness to ensure the strength of the product. The thickness of only the portion where the electrostatic sensor 40 is provided only needs to be thick enough to hold the electrostatic sensor 40, and is smallest compared to the portion of the partition wall 39 where the electrostatic sensor 40 is not provided. This allows the electrostatic sensor 40 to be closer to the liquid in the water storage container 19, enabling changes in capacitance to be detected with high sensitivity.

[0049] 14 and 15 are cross-sectional views of the air conditioning apparatus 1 according to the first embodiment of the present disclosure, viewed from above. The cross-sectional heights of FIGS. 14 and 15 are different. As shown in FIGS. 13 and 14, the air conditioning apparatus 1 has a distance restriction unit 41 that restricts the distance between the electrostatic sensor 40 and the water storage container 19. The distance restriction unit 41 has a front restriction unit 42 and a rear restriction unit 43.

[0050] The front regulating portion 42 is provided forward of the electrostatic sensor 40 in the insertion direction of the water storage container 19 when the water storage container 19 is attached to the hollow portion 10. Specifically, the front regulating portion 42 has a front water storage regulating portion 42a provided on the water storage container 19 and a front isolation regulating portion 42b provided on the isolation wall 39.

[0051] The front water storage restriction portion 42a has a shape in which a surface or a protrusion protrudes from the water storage container 19, or a shape in which a surface or a protrusion can be accommodated.

[0052] The front isolation restriction part 42b has a shape that allows it to be inserted and reinserted into the front water storage restriction part 42a. The gap distance between the front water storage restriction part 42a and the front isolation restriction part 42b is smaller than the minimum distance between the part of the isolation wall 39 where the electrostatic sensor 40 is provided and the side surface of the water storage container 19.

[0053] As a result, the minimum distance between the part of the isolation wall 39 where the electrostatic sensor 40 is installed and the side of the water storage container 19 on the front side regulating section 42 side does not vary more than the minimum distance, and even if the minimum distance varies due to the attachment and detachment of the water storage container 19, the variation in the electrostatic capacitance can be reduced, and the attachment of the water storage container 19 to the hollow section 10 and water at a predetermined level can be detected.

[0054] The rear regulating portion 43 is provided rearward of the electrostatic sensor 40 in the insertion direction of the water storage container 19 when the water storage container 19 is attached to the hollow portion 10. Specifically, the rear regulating portion 43 has a rear water storage regulating portion 43a provided on the water storage container 19 and a rear isolation regulating portion 43b provided on the partition wall 39.

[0055] The rear water storage restriction portion 43a has a shape in which the surface parallel to the separating wall 39 on which the electrostatic sensor 40 is provided protrudes from the water storage container 19.

[0056] The rear isolation restriction portion 43b has a shape that fits into the shape of the rear water storage restriction portion 43a. The gap distance between the rear water storage restriction portion 43a and the rear isolation restriction portion 43b is smaller than the minimum distance between the portion of the separation wall 39 where the electrostatic sensor 40 is provided and the side surface of the water storage container 19.

[0057] As a result, the minimum distance between the part of the isolation wall 39 where the electrostatic sensor 40 is installed and the side of the water storage container 19 on the rear side regulating section side does not vary more than the minimum distance, and even if the minimum distance varies due to the attachment and detachment of the water storage container 19, the variation in the electrostatic capacitance can be reduced, and the attachment of the water storage container 19 to the hollow section 10 and the water at a predetermined level can be detected.

[0058] Figure 16 is a cross-sectional view of the air conditioning apparatus 1 according to the first embodiment of the present disclosure, viewed from the front. As shown in Figure 16, the cavity and the water storage container have temporary fixing parts 44 that temporarily fix the water storage container 19 in the cavity 10 when the water storage container 19 is inserted to a predetermined position in the cavity 10. When the water storage container 19 is temporarily fixed in the cavity 10, the distance between the electrostatic sensor 40 and the water storage container 19 is regulated by the front regulating part 42 and the rear regulating part 43.

[0059] The temporary fixing portion 44 has a claw shape extending from the bottom surface of the cavity 10 toward the inside of the cavity 10. The water storage container 19 is provided with a shape corresponding to the temporary fixing portion 44, and the water storage container 19 is When the water container 19 is inserted into the cavity 10 , the temporary fixing portion 44 is caught on the water storage container 19 to temporarily fix the water storage container 19 in the cavity 10 .

[0060] This regulates the distance between the electrostatic sensor 40 and the water storage container 19, allowing for accurate detection of the electrostatic capacitance, and making it possible to detect the presence or absence of the water storage container 19 and the presence or absence of liquid in the water storage container 19.
