Description

  Aspects of the invention generally relate to a sanitary washing apparatus.

  For example, as a toilet seat device equipped with a human body detection sensor that detects a user entering a toilet room and a user leaving the toilet room, a toilet seat device provided with a human body detecting means using radio waves has been proposed. (Patent Document 1). The human body detecting means of the toilet seat apparatus described in Patent Document 1 uses high-frequency radio waves called microwaves or millimeter waves. The human body detection means of the toilet seat device described in Patent Document 1 is a front part in the upper part of the cleaning nozzle and the inside of the main body part of the toilet seat device in order to detect a user approaching the toilet seat device from the front of the toilet seat device as soon as possible. Provided in the department.

  However, the door of the toilet room where the sanitary washing apparatus is installed may be installed not only on the front surface of the sanitary washing apparatus but also on the side of the sanitary washing apparatus. In the configuration described in Patent Document 1, when the door of the toilet room is installed on the side of the sanitary washing device, when the user enters the detection area of the human body detection means, the user and the sanitary washing device The distance between may be relatively close. When the distance between the user and the sanitary washing device is relatively close, the speed at which the user moves toward the toilet seat device is relatively slow. Then, there is a possibility that the human body detection means cannot acquire information related to the user (user detection signal).

JP 2003-284655 A

  The present invention has been made based on the recognition of such a problem, and provides a sanitary washing apparatus that can more reliably acquire information about a user in a sanitary washing apparatus having a human body detection sensor using radio waves. The purpose is to do.

  A first invention includes a main body part, a human body detection sensor provided in the main body part for detecting at least a user entering a toilet room by radio waves, and a human body provided to be movable forward and backward with respect to the main body part. And the human body detection sensor is disposed in a region facing the rear surface of the main body portion and in a region rearward of the cleaning nozzle in a state of being retracted inside the main body portion. This is a sanitary washing device.

  According to this sanitary washing device, both when the toilet room door is installed in front of the sanitary washing device and when the toilet room door is installed on the side of the sanitary washing device, The distance between the toilet room door and the toilet room can be secured longer. Therefore, it is possible to secure a wider detection area of the human body detection sensor near the door. Therefore, the human body detection sensor detects a user who is relatively far from the sanitary washing apparatus, that is, a user who moves relatively toward the sanitary washing apparatus. Therefore, the human body detection sensor can detect the user who has entered the toilet room at an earlier stage. Thereby, the human body detection sensor can detect a user's entrance more reliably. That is, it can suppress that a human body detection sensor does not detect a user's entrance.

  A second invention is the sanitary washing device according to the first invention, wherein the human body detection sensor is disposed above the washing nozzle in a state of being retracted inside the main body.

  According to this sanitary washing device, it is possible to prevent the human body detection sensor from detecting the washing nozzle that performs forward and backward movement. Therefore, the detection accuracy by the human body detection sensor when the user enters the room can be improved.

  In a third aspect based on the second aspect, the main body has a case cover, and the human body detection sensor is arranged at the uppermost position in the region facing the rear surface, and is positioned higher than the human body detection sensor. Is a sanitary washing device characterized in that only the case cover exists.

  According to this sanitary washing device, disturbances other than the case cover can be suppressed. Therefore, the human body detection sensor can accurately detect the user's entry.

  A fourth aspect of the present invention is the sanitary washing apparatus according to the third aspect, wherein the uppermost part of the rear surface of the case cover is the uppermost part of the main body.

  According to this sanitary washing device, it is possible to reduce obstacles until radio waves radiated from the human body detection sensor through the case cover reach the user. Therefore, the human body detection sensor can accurately detect the user's entry.

  A fifth invention is the sanitary washing device according to the third or fourth invention, wherein the human body detection sensor is attached to the case cover.

  According to this sanitary washing device, the angle relationship between the surface of the case cover and the maximum directivity direction of the radio wave radiated from the human body detection sensor can be stabilized. Thereby, the attenuation degree of the electromagnetic wave by a case cover can be stabilized. Therefore, the human body detection sensor can accurately detect the user's entry.

  In a fifth aspect based on the fifth aspect, the mounting direction of the human body detection sensor with respect to the case cover includes a first mounting direction, a second mounting direction, and a third mounting direction. The first maximum directivity direction of the radio wave radiated from the human body detection sensor attached to the case cover in the first attachment direction and the human body detection attached to the case cover in the third attachment direction The third maximum directivity direction of the radio wave radiated from the sensor is from the second maximum directivity direction of the radio wave radiated from the human body detection sensor attached to the case cover in the second attachment direction. This is a sanitary washing device characterized by being symmetrical.

  According to this sanitary washing device, the maximum directivity direction of the human body detection sensor can be set to an optimum direction according to the position of the door of the toilet room. Therefore, the human body detection sensor can accurately detect the user's entry.

  According to a seventh invention, in any one of the first to sixth inventions, the electronic device further comprises a toilet lid pivotally supported so as to be openable and closable with respect to the main body, and the human body detection sensor further includes leaving the user. The sanitary washing device is characterized in that the toilet lid that is detected and opened is positioned behind the human body detection sensor.

  According to this sanitary washing device, when the human body detection sensor detects the user leaving the room, the toilet lid can be prevented from being damaged. Therefore, the human body detection sensor can accurately detect the user leaving the room.

FIG. 2A is a block diagram illustrating a main configuration of the sanitary washing device according to the present embodiment. FIG. 2B is a block diagram illustrating a modification of the human body detection sensor.

  The toilet device 10 shown in FIG. 1 includes a Western-style seat toilet (hereinafter simply referred to as “toilet” for convenience of explanation) 800 and a sanitary washing device 100 provided on the toilet 800. The sanitary washing device 100 includes a main body 110, a toilet seat 120, a toilet lid 130, and a human body detection sensor 140. The main body 110 is placed on the toilet bowl 800. Each of the toilet seat 120 and the toilet lid 130 is pivotally supported with respect to the main body 110 so as to be freely opened and closed.

  The human body detection sensor 140 is provided inside the main body 110 and detects the user entering the toilet room and the user leaving the toilet room. Details of the arrangement of the human body detection sensor 140 will be described later. The human body detection sensor 140 radiates (transmits) high-frequency radio waves such as microwaves or millimeter waves, and receives reflected waves from the detected object of the radiated radio waves. The human body detection sensor 140 detects the presence / absence and state of the detected object and outputs a detection signal thereof.

  As illustrated in FIG. 2A, the human body detection sensor 140 includes an antenna 141, a transmission unit 143, a reception unit 145, and a mixer unit 147. A radio wave in a frequency band of 10 kHz to 100 GHz such as a high frequency, a microwave, or a millimeter wave is radiated from an antenna 141 connected to the transmission unit 143. Specifically, for example, a transmission wave T1 having a frequency of 24.15 GHz is radiated from the antenna 141. A reflected wave or transmitted wave T <b> 2 from a detected object such as a human body is input to the receiving unit 145 via the antenna 141.

  Like the human body detection sensor 140 shown in FIG. 2A, the transmitting antenna and the receiving antenna may be a common antenna (antenna 141). Alternatively, as in the human body detection sensor 140 a illustrated in FIG. 2B, the transmission-side antenna 141 a may be connected to the transmission unit 143 and the reception-side antenna 141 b may be connected to the reception unit 145. That is, the human body detection sensor 140 illustrated in FIG. 2A may be replaced with the human body detection sensor 140a illustrated in FIG.

In the present embodiment, a case where the human body detection sensor 140 is a Doppler sensor using the Doppler effect will be described as an example.
A part of the transmission wave and the reception wave are respectively input to the mixer unit 147 and synthesized, and, for example, an output signal reflecting the Doppler effect is output. The detection signal output from the mixer unit 147 is output to the control unit 151.

The detection signal output from the mixer unit 147 has a waveform in which a high frequency signal is superimposed on a low frequency baseline. The high frequency component includes information on the Doppler effect. That is, when a detection object such as a human body moves, the wavelength of the reflected wave shifts due to the Doppler effect. The Doppler frequency ΔF (Hz) can be expressed by the following equation (1).

ΔF = Fs−Fb = 2 × Fs × v / c Equation (1)

Where Fs: transmission frequency (Hz)
Fb: reflection frequency (Hz)
v: object moving speed (m / s)
c: speed of light (= 300 × 10 ⁶ m / s)

When the object to be detected moves relative to the human body detection sensor 140, an output signal including a frequency ΔF proportional to the speed v is obtained as represented by the equation (1). The output signal has a frequency spectrum, and there is a correlation between the peak frequency corresponding to the peak of the spectrum and the velocity v of the moving object. Therefore, the velocity v can be obtained by measuring the Doppler frequency ΔF. In Japan, a frequency of 10.50 to 10.55 GHz or 24.05 to 24.25 GHz can be used for the purpose of detecting a human body.

  In addition, the human body detection sensor 140 of this embodiment is not limited to a Doppler sensor using the Doppler effect. The human body detection sensor 140 may be a distance measuring sensor using frequency modulation or pulse output.

  The cleaning nozzle 155 receives the driving force transmitted from the nozzle motor 153, and can advance from the inside of the main body 110 to the outside of the main body 110, or can retract from the outside of the main body 110 to the inside of the main body 110. . That is, the nozzle motor 153 can move the cleaning nozzle 155 forward and backward based on the signal transmitted from the control unit 151. An advancing opening (not shown) is provided in front of the cleaning nozzle 155 stored in the main body 110. The advance opening is provided in the casing 111 that forms the outer shape of the main body 110.

  In the present specification, the front is “front” when viewed from the user sitting on the toilet seat 120 in the normal use state, and the rear is “rear” when viewed from the user sitting on the toilet seat 120 in the normal use state. Further, the right side is referred to as “right side” and the left side is referred to as “left side” as viewed from the user standing in front of the toilet bowl 800.

  A nozzle shutter 115 (see FIG. 1B) is provided in front of the advance opening. The nozzle shutter 115 is provided to close the advance opening. For example, when the user operates the operation unit 200 while sitting on the toilet seat 120, the cleaning nozzle 155 advances into the bowl 801. At this time, the cleaning nozzle 155 advances into the bowl 801 by pressing the inner surface of the nozzle shutter 115 (the inner surface of the main body 110) and opening the nozzle shutter 115, for example.

  One or a plurality of water outlets 155 a are provided at the tip of the cleaning nozzle 155. The washing nozzle 155 can wash water such as a “butt” of a user sitting on the toilet seat 120 by jetting water from a water outlet 155 a provided at the tip of the washing nozzle 155. In the present specification, the term “water” includes not only cold water but also warm hot water.

  The toilet lid opening / closing unit 157 opens and closes the toilet lid 130 based on the signal transmitted from the control unit 151. The toilet seat opening / closing unit 159 opens and closes the toilet seat 120 based on the signal transmitted from the control unit 151.

FIG. 3 is a schematic plan view for explaining the difference in the installation position of the door of the toilet room.
FIG. 3A is a schematic plan view illustrating a toilet room in which a door is installed on the front (front) of the sanitary washing device. FIG. 3B is a schematic plan view illustrating a toilet room in which a door is installed on the side of the sanitary washing device.

  As illustrated in FIG. 3A, the door 311 of the toilet room 300 in which the sanitary washing device 100 is installed may be installed on the front (front) of the sanitary washing device 100. Alternatively, as shown in FIG. 3B, the door 311 of the toilet room 300 in which the sanitary washing device 100 is installed is installed on the side of the sanitary washing device 100 (on the left side in the example of FIG. 3B). Have been.

  When the door 311 of the toilet room 300 is installed in front of the sanitary washing device 100 as indicated by an arrow 351 shown in FIG. 3A, the user enters the detection region 148 of the human body detection sensor 140. Sometimes the distance between the user and the sanitary washing device 100 is relatively far. On the other hand, when the door 311 of the toilet room 300 is installed on the side of the sanitary washing device 100 as indicated by an arrow 353 shown in FIG. When entering 148, the distance between the user and the sanitary washing device 100 is relatively close.

  In general, at a position relatively close to the sanitary washing device 100, the user decreases the moving speed toward the sanitary washing device 100. That is, at a position relatively close to the sanitary washing device 100, the speed at which the user moves toward the sanitary washing device 100 is relatively slow. Therefore, when the door 311 of the toilet room 300 is installed on the side of the sanitary washing device 100, the human body detection sensor 140 is not connected to the toilet room 300 even if the user enters the detection area 148 of the human body detection sensor 140. The user who entered the room may not be detected.

In contrast, as shown in FIGS. 3A and 3B, the human body detection sensor 140 according to the present embodiment is an area inside the main body 110 and faces the rear surface 112 of the main body 110. Provided in the area.
The arrangement of the human body detection sensor 140 will be further described with reference to the drawings.

FIG. 4 is a schematic cross-sectional view showing the installation position of the human body detection sensor of the present embodiment.
FIG. 4A and FIG. 4B are schematic cross-sectional views taken along the cutting plane AA shown in FIG. Fig.4 (a) is typical sectional drawing showing the state which the toilet lid opened, and the toilet seat closed. FIG. 4B is a schematic cross-sectional view showing a state in which the toilet lid and the toilet seat are opened.

  The main body 110 of the sanitary washing device 100 has a casing 111 that forms the outer shape of the main body 110. As shown in FIGS. 4A and 4B, the casing 111 includes a case cover 111a and a case plate 111b.

  The case cover 111a has a first rear surface portion 112a and a second rear surface portion 112b. The first rear surface portion 112a has a surface inclined with respect to the horizontal direction. The second rear surface portion 112b is connected to the first rear surface portion 112a and extends in the vertical direction. The outer surface of the first rear surface portion 112 a and the outer surface of the second rear surface portion 112 b form the rear surface 112.

  Note that the case cover 111a is not limited to having the first rear surface portion 112a and the second rear surface portion 112b. The rear surface 112 of the case cover 111a may be formed by one part. Alternatively, the rear surface 112 of the case cover 111a may be formed by three or more parts. The casing 111 illustrated in FIG. 4A and FIG. 4B is an example, and is not limited thereto.

  As described above with reference to FIGS. 3A and 3B, the human body detection sensor 140 according to the present embodiment is provided in an area inside the main body 110 and facing the rear surface 112 of the main body 110. ing. Further, as shown in FIGS. 4A and 4B, the human body detection sensor 140 is provided in a region behind the cleaning nozzle 155 in a state of being housed in the main body 110 (retracted state). It has been. In other words, there is a gap C <b> 1 between the rear end portion of the cleaning nozzle 155 stored in the main body portion 110 and the front end portion of the human body detection sensor 140.

  According to this, both when the door 311 of the toilet room 300 is installed in front of the sanitary washing device 100 and when the door 311 of the toilet room 300 is installed on the side of the sanitary washing device 100. The distance between the human body detection sensor 140 and the door 311 of the toilet room 300 can be ensured longer than when the detection sensor 140 is provided in the front part of the main body 110. Therefore, a wider detection area 148 of the human body detection sensor 140 near the door 311 can be secured. Therefore, the human body detection sensor 140 detects a user at a position relatively far from the sanitary washing device 100, that is, a user moving at a relatively high speed toward the sanitary washing device 100. Therefore, the human body detection sensor 140 can detect the user who has entered the toilet room 300 at an earlier stage. Thereby, the human body detection sensor 140 can more reliably detect the user entering and leaving the user. That is, it can suppress that the human body detection sensor 140 does not detect a user's entrance and a user's leaving.

  Further, the human body detection sensor 140 is provided in a region above the cleaning nozzle 155 that is housed in the main body 110. In other words, there is a gap C <b> 2 between the upper end of the cleaning nozzle 155 that is housed in the main body 110 and the lower end of the human body detection sensor 140.

  According to this, it can suppress that the human body detection sensor 140 detects the washing nozzle 155 which performs advancing / retreating motion. Therefore, the detection accuracy by the human body detection sensor 140 of the user entering and leaving the user can be improved.

  In addition, the human body detection sensor 140 is provided at the top of the region facing the rear surface 112 inside the main body 110, and only the case cover 111 a exists above the human body detection sensor 140. In other words, there is no member other than the case cover 111a at a position above the human body detection sensor 140 inside the main body 110.

  According to this, disturbances other than the case cover 111a can be suppressed. Therefore, the human body detection sensor 140 can accurately detect the user entering and leaving the user.

The uppermost part of the rear surface of the case cover 111 a is the uppermost part of the main body 110.
According to this, it is possible to reduce obstacles until radio waves radiated from the human body detection sensor 140 through the case cover 111a reach the user. Therefore, the human body detection sensor 140 can accurately detect the user entering and leaving the user.

  As shown in FIGS. 4A and 4B, the opened toilet lid 130 is located behind the human body detection sensor 140. In other words, there is a gap C <b> 3 between the front end portion of the opened toilet lid 130 and the rear end portion of the human body detection sensor 140.

  According to this, when the human body detection sensor 140 detects the user leaving the room, the failure of the toilet lid 130 can be suppressed. Therefore, the human body detection sensor 140 can accurately detect the user leaving the room.

Next, a specific example of the mounting structure of the human body detection sensor will be described with reference to the drawings.
FIG. 5 is a schematic perspective view showing a specific example of the attachment structure of the human body detection sensor of the present embodiment.

  Case cover 111a of this embodiment has upper surface part 114 (refer to Drawing 4 (a) and Drawing 4 (b)). As shown in FIG. 5, the inner surface 114a of the upper surface 114 of the case cover 111a is provided with a protrusion 114b that protrudes substantially downward from the inner surface 114a. As shown in FIG. 5, the cover member 161 is fixed to the protruding portion 114 b by a fastening member 163 such as a screw. The human body detection sensor 140 of this specific example is attached to the cover member 161. That is, the human body detection sensor 140 of this specific example is attached to the case cover 111a via the cover member 161.

  According to this specific example, the angle relationship between the surface of the case cover 111a and the maximum directivity direction 149 of the radio wave radiated from the human body detection sensor 140 (see FIGS. 1A and 1B). Can be stabilized. Thereby, the attenuation degree of the electromagnetic wave by the case cover 111a can be stabilized. Therefore, the human body detection sensor 140 can accurately detect the user entering and leaving the user.

  In the present specification, the “maximum directivity direction” refers to a direction in which the intensity of the radio wave is maximum in the detection region 148 of the human body detection sensor 140.

FIG. 6 is a schematic perspective view showing another specific example of the mounting structure of the human body detection sensor of the present embodiment.
A support portion 114c that extends substantially downward from the inner surface 114a is provided on the inner surface 114a of the upper surface portion 114 of the case cover 111a. The support part 114 c supports the cover member 161. The human body detection sensor 140 of this specific example is attached to the cover member 161. That is, the human body detection sensor 140 of this specific example is attached to the case cover 111a via the cover member 161.
According to this example, the same effect as described above with reference to FIG. 5 can be obtained.

FIG. 7 is a schematic perspective view showing still another specific example of the mounting structure of the human body detection sensor of the present embodiment.
In this specific example, as described above with reference to FIG. 5, the cover member 161 is fixed to the protrusion 114b by a fastening member 163 such as a screw. The cover member 161 has a curved surface 161a. Further, the cover member 161 has an angle restricting portion 162 that protrudes downward from the lower surface of the cover member 161. As shown in FIG. 7B, the angle restricting portion 162 has a convex portion 162a protruding in the radially outward direction.

  A holding member 165 is attached to the cover member 161. The holding member 165 holds the human body detection sensor 140. As shown in FIG. 7B, the holding member 165 has a hole 166 that can be engaged with the angle restricting portion 162 of the cover member 161. The hole 166 includes a first concave portion 166a, a second concave portion 166b, and a third concave portion 166c that can be engaged with the convex portion 162a of the angle restricting portion 162. In the specific example shown in FIG. 7B, the convex portion 162 a of the angle restricting portion 162 is engaged with the second concave portion 166 b of the hole 166.

  The holding member 165 has a curved surface 165a. The curved surface 165 a of the holding member 165 can slide on the curved surface 161 a of the cover member 161.

  For example, when manufacturing the sanitary washing device 100 according to the present embodiment in a factory, the operator determines the concave portion of the hole 166 to be engaged with the convex portion 162a of the angle restricting portion 162, so that the human body detection sensor 140 is The maximum directivity direction 149 can be set in a predetermined direction.

For example, the operator engages the convex portion 162a of the angle restricting portion 162 with the first concave portion 166a of the hole 166, so that the maximum pointing direction of the human body detection sensor 140 is set as shown in FIGS. 3 (a) and 3 (c). The first maximum pointing direction 149a shown in FIG.
For example, the operator engages the convex portion 162a of the angle restricting portion 162 with the second concave portion 166b of the hole 166, so that the maximum pointing direction of the human body detection sensor 140 is set to FIG. 3 (a) and FIG. 3 (c). The second maximum directivity direction 149b shown in FIG.
For example, the operator engages the convex portion 162a of the angle restricting portion 162 with the third concave portion 166c of the hole 166, so that the maximum pointing direction of the human body detection sensor 140 is set to FIG. 3 (a) and FIG. 3 (c). The third maximum pointing direction 149c shown in FIG.
The first maximum directivity direction 149a and the third maximum directivity direction 149c are symmetrical with respect to the second maximum directivity direction 149b.

  According to this specific example, the maximum directivity direction 149 of the human body detection sensor 140 can be set in an optimum direction according to the position of the door 311 of the toilet room 300. Therefore, the human body detection sensor 140 can accurately detect the user entering and leaving the user.

The determination of the concave portion of the hole 166 to be engaged with the convex portion 162a of the angle restricting portion 162 may be performed not at the factory but at the installation site of the sanitary washing device 100.
Further, the angle restricting portion 162 does not necessarily have the convex portion 162a. The hole 166 does not necessarily have the first recess 166a, the second recess 166b, and the third recess 166c. For example, the operator may set the maximum directivity direction 149 of the human body detection sensor 140 in a predetermined direction by using a jig.
In addition, since at least one of the holding member 165 and the cover member 161 has a lock function (not shown), the setting of the maximum directivity direction 149 of the human body detection sensor 140 can be easily performed at the installation site of the sanitary washing device 100. Good.

FIG. 8 is a schematic perspective view showing still another specific example of the mounting structure of the human body detection sensor of the present embodiment.
In this specific example, the functional component 167 of the sanitary washing device 100 is provided on the inner surface 116a of the bottom surface portion 116 (see FIGS. 4A and 4B) of the case plate 111b. As shown in FIG. 8, the holding member 165 is fixed to the functional component 167 by a fastening member 163 such as a screw. The holding member 165 holds the human body detection sensor 140. That is, the human body detection sensor 140 of this example is attached to the case plate 111b via the holding member 165 and the functional component 167.
