Abstract

PROBLEM TO BE SOLVED: To provide a sink having a water tank which eliminates the need of increasing the strength of the bottom in the water tank by thickening a material or reinforcing the tank.SOLUTION: The sink having the water tank comprises: a horizontally-long water tank 1 which has an internal dimension of 75-85 cm in the width direction when viewed from above; a horizontally-long side-swollen portion 2 which is provided on one side wall in the water tank 1 so as to expand toward an inner side of a main body 11 of the water tank 1, and has an internal dimension of 9-12 cm in a depth direction when viewed from above; a bottom 6 of the side-swollen portion which is provided in the side-swollen portion 2 so as to swell downward; and a drain outlet 61 of the swollen portion which has a bore that fits to the bottom 6 of the side-swollen portion.

Description

  The present invention relates to a sink having a water tank provided with a side bulging portion that opens on the inner side of the main body of the water tank on one side wall.

  2. Description of the Related Art Conventionally, a water tank having a laterally bulging portion is known in which a drain outlet looks into the bulging portion. Generally, a drainage device having a diameter corresponding to a standard size (for example, a diameter of about 180 mm) is attached to the drainage port. In order to attach this drainage device, an opening having the same diameter as that of the drainage device is provided at the bottom of the water tank (see, for example, Patent Document 1).

JP 2008-297824 A (page 5, FIG. 3)

  However, in Patent Document 1, although the drainage port looks into the bulging portion because the drainage device has a large diameter, the drainage port does not completely fit into the bulging portion, and the large-diameter opening has a water tank. Because it is at the bottom, if a large load is applied to the bottom of the aquarium, a large stress is generated in the opening. Therefore, it is necessary to increase the thickness of the material, and if it is a resin aquarium, reinforcement with fiber reinforced resin is required. There is a problem.

  The present invention has been made paying attention to such problems, and provides a sink having a water tank that does not need to supplement the strength of the bottom of the water tank by increasing the thickness of the material or reinforcing the material. With the goal.

In order to solve the above problems, the sink having the water tank of the present invention is:
On the side wall in a horizontally long water tank whose inner width in the width direction is 75 to 85 cm in plan view, on the side of the oblong side in which the inner diameter in the depth direction is 9 to 12 cm in plan view with the inner side of the main body of the water tank open A bulging portion provided with a side bulging portion and provided with a laterally bulging bottom portion that is bulged downward in the side bulging portion and having a diameter that fits in the bottom portion of the side bulging portion It features a drain outlet.
According to this feature, the strength of the bottom of the main body can be reduced and the thickness of the material can be reduced by moving the drain outlet, which is a large opening disadvantageous in strength, from the bottom of the main body of the water tank to the bulging portion. In addition, it is possible to secure the dimensions in the water tank to such an extent that, for example, a wok can be added, and if the versatile frontage is 90 to 105 cm, the lower part of the water tank can be stored in the cabinet. In addition, since the bottom of the side bulge portion is horizontally long in a plan view while the diameter of the bulge portion drainage port is a predetermined length (45 to 55 mm) or more, the lateral dimension is larger than the bulge portion drainage port diameter. There is an advantage that the capacity of the garbage basket can be sufficiently secured without being affected by the size of the drainage port even when, for example, the garbage basket for trapping the soot is accommodated at the bottom of the side bulging part.

The sink with the water tank of the present invention,
The water tank is made of resin.
According to this feature, the thickness of the material can be made as thin as possible, and the reinforcement can be reduced even when the bottom is reinforced with fiber reinforced resin or the like.

The sink with the water tank of the present invention,
The bottom part of the main body of the water tank is the part where the part connected to the bottom part of the side bulge is the lowest at the bottom part of the main body, and the part connected to the side wall of the water tank facing the side swell part where the swell part drainage port is arranged And the bottom of the main body gradually increases.
According to this feature, conventionally, since the drain outlet is closer to the center of the bottom surface of the main body, the slope for drainage on the bottom surface of the main body had to be a mortar-shaped curved surface toward the center of the drain outlet. Is completely transferred from the bottom surface of the main body of the water tank into the bulging portion, so that a flat shape may be used as long as it is inclined toward the bulging portion, and the shape of the bottom surface of the main body can be simplified. This facilitates production of a mold for molding.

It is a perspective view which shows the water tank in Example 1. FIG. It is a sectional side view which shows the water tank in Example 1. FIG. (A) is a perspective view which shows the side bulging part in Example 1, (b) is a perspective view which similarly shows the state which attached the apron, (c) shows the back surface of an apron similarly. It is a perspective view. (A) is a perspective view which shows the storage device in Example 1, (b) is a perspective view which shows the storage device in a modification. It is a perspective view which shows the draining basket in Example 1. FIG. It is the bottom perspective view which showed the stress analysis by FEM of the water tank in a prior art example. It is a top perspective view like FIG. It is the bottom perspective view showing the stress analysis by FEM of the water tank in Example 1. It is a top perspective view like FIG. It is the bottom perspective view showing the stress analysis by FEM of the water tank in Example 2. It is a top perspective view like FIG.

  EMBODIMENT OF THE INVENTION The form for implementing the sink with the water tank concerning this invention is demonstrated below based on an Example.

  A sink having a water tank according to the first embodiment will be described with reference to FIGS. 1 to 5 and FIGS. Hereinafter, the lower left direction in FIGS. 1 and 5 and the left direction in FIG. 2 will be described as the front direction of the sink having a water tank. 6 to 11 show the strength analysis by FEM (finite element method) which is a well-known numerical analysis method, and large stress is applied to the dark gray portion in the drawing.

  First, the strength of the bottom surface of the water tank will be described. As shown in FIG. 1, the water tank 1 of the sink has an upper opening, is longer than the depth dimension in a plan view, and has an inner method of 75 to 85 cm in the width direction. A part of the back side surface of the water tank 1 further enters the back side, and is formed with a side bulging portion 2 having an inner depth of 9 to 12 cm in a depth direction in a plan view. The side bulge portion 2 is longer than the depth dimension in plan view. A water faucet (not shown) can be attached to the deck portion 3 adjacent to the side bulging portion 2, and its height is lower than that of the top plate upper surface 4 and is flat. The side bulging portion bottom 6 of the side bulging portion 2 bulges further downward from the main body bottom 5 of the water tank 1 and is formed in a horizontally long shape in plan view. The side bulging portion bottom 6 has a bulging portion drain opening 61 having a relatively small diameter that can be accommodated in the side bulging portion bottom 6 to which the drainage device is connected.

  Accordingly, in the conventional water tank 100 shown in FIGS. 6 and 7, since the drain port is substantially in the center of the bottom surface of the main body and has a large diameter, when a load is applied to the bottom surface 915 of the water tank body, the opening that is the drain port 91 is relatively Although a large stress was applied, in the aquarium 1 of this embodiment shown in FIGS. 8 and 9, the stress applied to the opening which is the bulging portion drain port 61 is reduced by making the drain port a small diameter and arranging it on the back side. Can be suppressed.

  In addition, by moving the drainage opening, which is a large opening disadvantageous in strength, to the bottom of the water tank 1 from the main body bottom 5 of the water tank main body to the bulging part, the strength of the main body bottom 5 is reduced and the thickness of the material can be reduced. The dimensions of the water tank 1 can be sufficiently secured to such an extent that, for example, a wok can be added, and if the highly versatile frontage is a 90 to 105 cm cabinet, the lower part of the water tank 1 can be stored in the cabinet. The lateral bulge bottom 6 is laterally long in plan view, while the diameter of the bulge drain 61 can be a predetermined length (45 to 55 mm) or more. The diameter can be larger than 61, and there is an advantage that the capacity of the garbage basket can be sufficiently ensured without being influenced by the size of the drainage port even when the garbage basket for trapping, for example, is accommodated in the bottom portion 6 of the side bulge.

  Moreover, since the bottom face strength of the water tank 1 can be reduced, if the water tank 1 is made of resin, the material can be made as thin as possible, and even when the bottom face of the water tank 1 is reinforced with fiber reinforced resin or the like, the reinforcement should be reduced. Is possible. Since there is no deformation around the bulging portion drain 61, water leakage can be prevented. Looking at the FEM analysis results, the stress at the bottom of the aquarium is smaller in the aquarium 1 of the embodiment according to the present invention shown in FIG. 8 than in the conventional aquarium 100 shown in FIG. Then, in the conventional water tank 100 shown in FIG.

  Next, it will be described that the drainage of water can be suppressed when the drainage is poured into the water tank vigorously. In FIG. 2, an apron 7 is erected on the boundary between the water tank body 11 and the side bulging part 2 from the height substantially equal to the body bottom part 5, and on the boundary between the body bottom part 5 and the side bulging part bottom part 6. The drainage guide path 62 for guiding drainage is formed from the front side of the apron 7 to the bottom part 6 of the side bulge part.

  Since the apron 7 is erected from the height substantially equal to the bottom portion 5 of the main body, the drainage that has flowed into the water tank 1 vigorously is deflected so that the apron 7 is temporarily blocked. Then, the drained wastewater is led from the drainage inlet 621 formed by the lower end of the apron 7 and the drainage guide path 62 to the bulging portion drainage port 61. Since the drainage is steeped and hardly splashes even if it hits the side wall 21, the drainage does not fall on the bottom of the container 221, and the dirt of the container 221 can be reduced.

  Moreover, since the apron 7 has a plate-like structure with the same thickness over the entire surface, the same material and the same construction method as the water tank 1 can be used when the water tank 1 is produced by compression molding such as BMC. The apron 7 can be made to have the same texture as that of the aquarium 1, and the appearance can be improved.

  Further, since the bulging portion drain port 61 is completely accommodated in the side bulging portion 2, no drain port is disposed at the bottom of the water tank body 11 and is concealed by the apron 7. In addition to being able to be used, conventionally, in a water tank having a drain outlet at the center of the bottom of the main body, when the lid that closes the drain outlet is made of a thermoplastic resin, when the heated cooking utensil is put into the water tank, it is thermally deformed. Although it was necessary to avoid it, it was no longer necessary.

  Next, the storage device will be described. As shown in FIG. 4 (b), the storage device 222 is a modification of the storage device according to the present invention, whereas the storage device 221 shown in FIG. It is comprised with the plate-shaped member which opened the hole for. By making the container bottom from a wire to a plate, it becomes more difficult for the container 222 to be entangled compared to the container 221 in the case where the dust splashed together with the drainage is a wire.

  Further, since the container bottom 2221 is plate-shaped and has a minimum number of holes for drainage, it is possible to suppress water from entering the container 222 that jumps from below. Further, foreign matter such as dust mixed in the waste water is also splashed up, but since it is a minimum hole, it is possible to suppress the foreign matter from being caught by the hole and attached.

  The storage units 221 and 222 are respectively composed of a front surface portion and storage device bottom portions 2211 and 2221, the rear surface is the side bulging portion inner wall 21 of the water tank 1, and the side surface is the side bulging portion side wall 26 of the water tank 1. By using these parts of the water tank 1, the container can be made a simple structure, and can be easily maintained by removing the container.

  Next, the design properties will be described. As shown in FIGS. 3 (a) and 3 (b), the bulging portion drain port 61 is sized to be completely accommodated in the side bulging portion bottom 6, and the side bulging portion bottom 6 and the water tank body. Since the apron 7 is erected on the boundary with the bulge 11 and the container 221 is above the bulge drain 61, the bulge drain 61 can be completely concealed, and the water tank is clean. Can show. Moreover, since the drain opening is concealed and a lid that is always exposed to the drainage is not required, the drain opening can be easily maintained.

  Next, the periphery of the side bulging portion 2 will be described. The side bulging portion bottom 6 is provided with a strainer (not shown) that captures dust. Dust larger than the drainage inlet 621 can be captured here, but dust smaller than that is captured by the strainer to prevent the outflow of dust to a drain pipe (not shown).

  4 (a) and 4 (b), the containers 221 and 222 are substantially L-shaped in a side view, and the left and right side bulging portion side walls 26 shown in FIG. Steps 23 on which the left and right sides of the bottoms of the containers 221 and 222 are placed are formed. Further, the left and right of the standing portions of the containers 221 and 222 are engaged with the step portion 24 of the side bulging portion side wall 26. As described above, since the bottoms and standing portions of the storage units 221 and 222 are detachably supported by the step portions 23 and 24 of the side bulging portion side wall 26, the articles are stored in the storage units 221 and 222. When the storage units 221 and 222 are inclined to the front, the movement can be prevented by the step portion 24, and when the storage devices 221 and 222 are inclined to the rear, the step portion 23 can prevent the movement and can be stably stored.

  Further, as shown in FIG. 3A, a convex portion 25 is formed on the left and right side bulging portion side walls 26, and is approximately J in a side view of the upper part of the back surface of the apron 7 shown in FIG. It is detachably engaged with the character-shaped engaging portion 71 upward. Since the engaging portion 71 is substantially J-shaped, the convex portion 25 is engaged from the front and rear and the upper side, and is engaged at a position higher than the center of gravity of the apron 7, so that it is stable despite being easy to attach and detach. Can be attached.

  Furthermore, if it is a resin-made water tank, the said step part 23, the step part 24, and the convex part 25 can be shape | molded integrally, and the connection part of the step part 23, the step part 24 and the convex part 25, and the side bulging part side wall 26 will be demonstrated. Since it has a smooth R shape, it can be easily removed even if dirt is attached, compared to the case where pins or the like are used for the stepped portion.

  Next, the main body bottom 5 will be described. As shown in FIG. 2, the main body bottom portion 5 gently descends and slopes from the user's front to the back, and drainage can be reliably performed only by making the boundary between the main body bottom portion 5 and the side bulging portion bottom portion 6 the lowest. Therefore, conventionally, since the drain outlet is closer to the center of the bottom of the water tank body, the slope for draining the bottom of the body has to be a mortar-shaped curved surface toward the center of the drain outlet. When the water outlet 61 is completely transferred from the water tank body bottom 5 into the side bulging part 2, the water tank body bottom 5 may be flat if inclined, and the structure can be simplified. This makes it easy to manufacture a mold for the purpose.

  Next, as shown in FIG. 5, a structure in which a drain basket 81, a draining plate or a cutting board (not shown), etc. can be stretched will be described. By making the upper part heights of the deck part 3 and the apron 7 equal and smoothly connected to each other, a draining basket 81 or a draining plate (not shown) is provided between the deck part or the apron 7 and the top plate front edge 41. Or a cutting board etc. can be spanned and it can be made slidable by connecting smoothly.

  In addition, since the apron 7 is stably placed as described above, the draining basket 81, a draining plate or a cutting board (not shown), and the like can be placed stably.

  Further, as shown in FIG. 3A, the apron 7 has at least four corners at the upper and lower corners by providing the side bulging portion side wall 26 with step portions 27 that support at least the left and right ends of the apron 7 from the rear. The draining basket 81, a draining plate or a cutting board (not shown), etc. can be supported more stably.

  Furthermore, as shown in FIG. 5, a draining basket 81 or a draining basket front end 811 such as a draining plate or cutting board (not shown) is mounted on a top top front edge 41 that is substantially L-shaped and horizontal when viewed from the side. The placement part which constitutes the placing part to be placed and is placed on the horizontal deck part 3 and / or the apron 7 in a substantially L-shape in a side view on the rear side facing the front end part 811 of the draining basket The difference between the heights of the draining basket rear end 812 and the draining basket front end 811 and the draining basket rear end 812 is equal to the difference in height between the deck portion 3 and the top plate front edge 41. By adopting such a structure, by using these parts of the water tank 1, the container can be made a simple structure, and can be easily maintained by removing the container, It becomes possible to horizontally support a draining plate or cutting board (not shown).

  Next, the cleanability of the water tank 1 will be described. As shown in FIG. 1, the front of the water tank 1 has no step between the top edge 41 of the top plate and the bottom 5 of the top plate, and the rear of the water tank 1 does not reach between the top surface 4 of the top plate and the deck 3. There are no steps, there is no step between the deck portion 3 and the main body bottom 5, and the corners and corners are formed in a smooth R shape. Thereby, the water tank 1 can reduce a step part, and cleanability improves by making a corner | angular part and a corner | angular part into a smooth R shape.

  Next, a sink having a water tank according to Example 2 will be described with reference to FIGS. The same components as those in the above embodiment are denoted by the same reference numerals and the description thereof is omitted.

  The water tank 51 is open at the top and is formed to be horizontally longer than the depth dimension in plan view. A part of the back side surface of the water tank 51 is formed with a side bulging portion 52 that further enters the back side. The side bulging portion 52 is longer than the depth dimension in plan view. A water faucet (not shown) can be attached to the deck portion 3 adjacent to the side bulging portion 52, and the height thereof is lower than the top surface 4 of the top plate (see FIG. 1). The side bulging portion bottom portion 56 of the side bulging portion 52 has the same height as the main body bottom portion 55 of the water tank 51. The side bulging portion bottom portion 56 is opened with a bulging portion drain port 92 having a small diameter enough to accommodate the side bulging portion bottom portion 56 connected to the drainage device.

  Accordingly, in the conventional water tank 100 shown in FIGS. 6 and 7, since the drain port is substantially in the center of the bottom surface of the main body and has a large diameter, when a load is applied to the bottom surface 915 of the water tank body, the opening that is the drain port 91 is relatively Although a large stress was applied, in the water tank 51 of this embodiment shown in FIGS. 10 and 11, the stress applied to the opening which is the drainage port 92 can be suppressed small by arranging the drainage port with a small diameter on the back side. it can.

  In addition, since the bottom strength of the water tank 51 can be reduced, if the water tank 51 is made of resin, the material can be made as thin as possible, and even when the bottom surface of the water tank 51 is reinforced with fiber reinforced resin or the like, the reinforcement should be reduced. Is possible. Moreover, since there is no deformation around the drain port due to the load, water leakage can be prevented.

  Next, it will be described that the drainage of water can be suppressed when the drainage is poured into the water tank vigorously. The apron 7 is erected at a boundary between the water tank main body and the side bulging portion 52 from a position slightly higher than the main body bottom 55 (see FIG. 1). Since the apron 7 is erected from a position slightly lower than the bottom 55 of the main body, when the water is vigorously flowed into the water tank 51, the water is deflected so that the apron 7 is temporarily blocked. Then, the offended water is guided from the opening formed by the lower end of the apron 7 and the main body bottom 55 to the drain. Since the water is steeped and hardly splashes even when it hits the side wall 21 of the side bulging portion, the bottom of the container 22 does not fall on the water, and dirt can be reduced.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.

For example, the sink with the water tank of the present invention is:
An apron stands on the boundary between the tank body and the side bulging part, and the lower part of the apron is erected from a height substantially equal to the bottom of the body. A path may be formed from the front of the apron to the bottom surface of the side bulging portion, and a container may be detachably provided in the side bulging portion on the back surface of the apron.
By doing in this way, even if drainage is poured into the water tank vigorously, it is temporarily blocked by the apron, and the momentum is lost. And the drained drained water is led to the drainage outlet from the drainage inlet formed by the lower end of the apron and the drainage guideway, but the drainage is strained and hits the back wall of the side bulge. Since there is little jumping up, drainage does not fall on the bottom of the container, and the dirt on the container can be reduced.

Also, for example, the sink with the water tank of the present invention is
The bottom of the container is plate-shaped and may have a plurality of holes for draining.
By doing so, the bottom surface of the container is plate-shaped and has only a minimum number of holes for drainage, so that it is possible to suppress the intrusion of water into the container that jumps from below. Further, foreign matter such as dust mixed in the waste water is also splashed up, but since it is a minimum hole, it is possible to suppress the foreign matter from being caught by the hole and attached.

Also, for example, the sink with the water tank of the present invention is
The container is configured at least in a substantially L shape in a side view of the front surface and the bottom of the container, the rear surface is disposed on the inner wall of the lateral bulging portion of the water tank, and the side surface is disposed on the side wall of the lateral bulging portion of the water tank Good.
By doing in this way, a container can be made into a simple structure by utilizing the site | part of these water tanks, and if a container is removed, it can maintain easily.

Also, for example, the sink with the water tank of the present invention is
Steps on which the left and right sides of the container are placed are formed on the side walls of the left and right side bulges, and the erection part of the container is formed on the steps of the side walls of the side bulges. The left and right sides of the left and right side bulges have convex portions formed on the upper side walls thereof, and are detachably engaged with a substantially J-shaped engagement portion in a side view of the upper part of the back surface of the apron. The joint part is substantially J-shaped and engages the convex part from front to back and from above, the step part and convex part are molded integrally with the water tank, and the step part and convex part and the side bulge part side wall The connecting portion may have a smooth R shape.
By doing in this way, when engaging a container and an apron with a water tank, compared with a pin etc., a stain | pollution | contamination is hard to adhere and it is easy to remove even if it adheres.

Furthermore, for example, the sink with the water tank of the present invention is:
A water faucet can be attached to the deck portion adjacent to the side bulging portion of the water tank, the height of which is lower than the top surface of the top plate, and the top height of the deck portion and the apron is made equal. And may be connected smoothly.
By doing in this way, a draining basket, draining plate, cutting board, etc. can be spanned between the deck section or apron and the top edge of the top surface, and it is slidable by being smoothly connected. be able to.

Also, for example, the sink with the water tank of the present invention is
A convex portion is formed on the upper side walls of the left and right lateral bulging portions, and a substantially J-shaped engaging portion is formed on the back surface of the apron in a side view, and the engaging portion is located above the convex portion. May be engaged.
By doing in this way, since the engaging part is substantially J-shaped, the convex part is engaged from the front and rear and above, and is engaged at a position higher than the center of gravity of the apron, so that the attachment and detachment is easy. Nevertheless, it can be mounted stably. Thereby, even if it puts on an apron, such as a draining basket, a draining plate, and a cutting board, it is stabilized.
