Description

Technical Field

[0001] The invention relates to a tableware washing machine which can pull a washing tank out of a shell body to accommodate tableware and wash the tableware. Background Art

[0002] Conventionally, the mainstream structure of a built-in dishwasher used in a state of being assembled in an integrated kitchen is that a washing tank having an openable and closable door at the front is fixed in a housing.

[0003] In recent years, however, dishwashers that pull out a washing tank having an upper opening from a housing to accommodate and wash tableware have become mainstream, as disclosed in, for example, Japanese Patent Application Laid-Open No. 2007-135650 (hereinafter referred to as "Patent Document 1").

[0004] The dishwashing machine disclosed in Patent Document 1 includes: a washing tank having an opening at the top for accommodating tableware; a housing for supporting the washing tank so that it can be freely pulled out and pushed in along the front-back direction; a detergent inlet provided outside the washing tank for injecting detergent into the washing tank; and an injection path connecting the detergent inlet and the washing tank. In addition, detergent is injected from the detergent inlet provided at a position independent of the washing tank. Thus, detergent can be reliably injected regardless of the size and shape of the tableware inserted into the washing tank.

[0005] A dishwasher including a detergent storage container in a washing tank is disclosed in, for example, Japanese Patent Application Laid-Open No. 2000-225087 (hereinafter referred to as "Patent Document 2").

[0006] The dishwashing machine disclosed in Patent Document 2 has a detergent container that is detachable from the inner wall of a washing tank or integrally mounted on the inner wall of the washing tank. The detergent container is mounted at a height substantially the same as a water supply port for washing water provided on the inner wall of the washing tank or at a position above the water supply port. Thus, before washing dishes, the possibility of detergent spilling, flowing out, or solidifying is prevented, and dishes, etc. can be effectively washed.

[0007] However, in the structure of the dishwasher of Patent Document 1, when detergent is added from the upper opening, the detergent flows directly into the washing tank. In other words, the conventional dishwasher cannot store detergent in advance. Therefore, when using the dishwasher, the user must put the required amount of detergent into the washing tank each time.

[0008] Therefore, as disclosed in Patent Document 2, it is considered to install a detergent container in the washing tank. In this case, the detergent in the detergent container may solidify due to repeated moisture and dryness in the washing tank. In addition, the volume of the washing tank is reduced due to the installation of the detergent container. Therefore, the space for placing tableware is reduced. Summary of the invention

[0009] The invention provides a dishwashing machine, which stores detergent outside a washing tank to prevent the detergent from solidifying, and has good convenience in use while ensuring the volume of the washing tank.

[0010] The dishwashing machine of the present invention comprises: a washing tank having an opening at the top for accommodating tableware; a housing for supporting the washing tank so that it can be freely pulled out and pushed in along the front-back direction; a detergent tank provided at the front outside of the washing tank for storing liquid detergent; and a detergent discharge path for connecting the detergent tank and the washing tank. In addition, the detergent tank is configured so that it can be freely pulled out and pushed in along the left-right direction relative to the washing tank.

[0011] According to the dishwasher of the present invention, a detergent tank is provided outside the washing tank and can be freely pulled out and pushed in. Thus, the detergent can be stored in the detergent tank outside the washing tank, thereby preventing the detergent from solidifying. In addition, the volume of the washing tank can be increased by the amount of detergent tank not being arranged in the washing tank. Moreover, the user can easily put in the detergent by attaching and detaching the detergent tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Embodiments of the present invention will be described below with reference to the drawings. However, the present invention is not limited to the embodiments.

[0019] (Implementation Method 1)

[0020] The following reference Figure 1 A schematic structure of the dishwasher according to the first embodiment will be described.

[0021] Figure 1 1 is a schematic side view of the dishwasher in the state where the washing tank 1 is pulled out from the housing 2 in the first embodiment. Figure 1 A schematic side view showing a state in which washing tank 1 of a dishwasher is pulled out from housing 2 of the dishwasher.

[0022] The dishwasher of Embodiment 1 is a built-in dishwasher installed in, for example, a kitchen or the like.

[0023] In the first embodiment, as shown in the figure, the front is described as the direction in which the door body 3 and the washing tank 1 are pulled out, and the rear is described as the direction in which the washing tank 1 is stored and the door body 3 is closed. In addition, hereinafter, the side of the opening 1a of the washing tank 1 of the dishwasher is described as the upper side, the opposite side is described as the lower side, and the right side is described as the right side and the left side is described as the left side when viewed from the front of the door body 3.

[0024] like Figure 1 As shown, the dishwasher of Embodiment 1 includes a housing 2, a washing tank 1 disposed inside the housing 2, a side wall 12, a detergent tank 15, a control device 19, and a door 3 for opening and closing the opening of the housing 2.

[0025] The washing tank 1 has an opening 1a at the top, and a basket 7 for accommodating tableware 8 is arranged inside. The washing tank 1 has a first rail 5 fixed at the bottom. On the other hand, the housing 2 has a second rail 6 fixed inside the inner surface. The first rail 5 is supported so as to be movable along the second rail 6 of the housing 2. Thus, the washing tank 1 is supported so as to be freely movable from the housing 2 in the front-rear direction (in the Figure 1 (left and right directions on the paper) pull out and push in.

[0026] The washing tank 1 is provided with a plane portion 23 disposed in front of the opening portion 1a at the upper front portion of the outer side. The plane portion 23 is provided with an operation portion 24 and a display portion 25. The operation portion 24 sets the washing program of the dishwasher, the power on and off, etc. according to the operation of the user. The display portion 25 is used to display the washing status, the operation status, the time, etc. In addition, an operation display substrate (not shown) for controlling the operation of the plane portion 23 is disposed on the back side of the surface where the operation portion 24 and the display portion 25 are disposed.

[0027] The side walls 12 are disposed on both sides between the cleaning tank 1 and the door body 3. The side walls 12 connect the cleaning tank 1 and the door body 3 so that they can move integrally. At this time, there is a front space portion 13 formed by dividing the front surface side of the cleaning tank 1, the rear surface side of the door body 3, the side walls 12 and the flat surface portion 23.

[0028] The door body 3 is provided with a handle 4 protruding forward on the top. The handle 4 is for the user to hold and is used to pull the cleaning tank 1 out of the housing 2 and push it in.

[0029] In addition, washing water for washing tableware in the washing tank 1 is supplied to the dishwasher of the first embodiment according to the path shown below. Specifically, first, washing water such as tap water is supplied to a water supply path such as a water supply hose from a branch faucet on the integrated kitchen (not shown). The supplied washing water is supplied to the washing tank 1 at a required water level and in a required amount through a water supply pump and a water supply valve (not shown) via the water supply path. Water is supplied to the washing tank 1 according to the path constructed as described above.

[0030] A circulation pump 9 is disposed at the lower outer side of the washing tank 1. The circulation pump 9 circulates the washing water supplied to the washing tank 1 through the circulation path, and sprays the washing water from the washing nozzle 11. The sprayed washing water can be used to wash the tableware 8. In addition, a heater 10 for heating the washing water is also disposed near the bottom of the washing tank 1.

[0031] In addition, the dishwasher of the first embodiment includes a drainage path for draining the washing water from the washing tank 1. The drainage path is composed of a drainage pump and a drainage hose (not shown). When the washing and rinsing of the tableware 8 is completed, the drainage pump is driven to drain the washing water to the outside through the drainage hose. In other words, the drainage path is configured to drain the washing water in the washing tank 1 to a sink in the kitchen.

[0032] A detergent tank storage portion 14 is disposed in the front space portion 13 located in the front of the outer side of the washing tank 1. A detergent tank 15 is accommodated in the detergent tank storage portion 14 in a manner that the detergent tank 15 can be pulled out and pushed in freely. The detergent tank storage portion 14 is welded or screwed to one side of the side wall 12, or is formed integrally with the side wall 12. In addition, a structure in which the detergent tank storage portion 14 is provided on the front surface of the washing tank 1 may also be adopted.

[0033] The dishwasher of Embodiment 1 is configured as described above.

[0034] Next, refer to Figure 2 and Figure 3 The structure around detergent tank 15 of the dishwasher will be described.

[0035] Figure 2 It is a schematic front view of the dishwasher showing a state in which detergent tank 15 is in the process of being stored or pulled out. Figure 3 It is a schematic front view showing the dishwasher in a state where detergent tank 15 is stored.

[0036] like Figure 2 and Figure 3 As shown, the detergent tank storage portion 14 has a cavity-like space. Thus, the detergent tank 15 is stored in the space of the detergent tank storage portion 14 in a manner that allows it to be freely pulled out and pushed in. When viewed from the front (the front side of the door body 3), the detergent tank 15 is stored in a manner that allows it to be freely pulled out and pushed in, for example, along the left-right direction (sideways).

[0037] In addition, if Figure 1 As shown, detergent tank storage portion 14 is disposed substantially below (including below) plane portion 23 (operation portion 24 or display portion 25 ), for example, to the right of the center of washing tub 1 , for storing detergent tank 15 .

[0038] In addition, Figure 2 and Figure 3 In the figure, the structure in which the detergent tank 15 is pulled out to the right from the detergent tank storage portion 14 is shown as an example, but it is not limited to this. For example, the detergent tank storage portion 14 and the detergent tank 15 may be arranged at the same Figure 2 , Figure 3 In this case, it is desirable to configure the detergent tank 15 to be pulled out from the detergent tank storage portion 14 to the left.

[0039] According to the above structure, when the washing tank 1 is completely stored in the housing 2, the detergent tank 15 is not conspicuous. Therefore, the dishwasher can be constructed with a simple design. In addition, the space (front space 13) for storing the detergent tank 15 outside the washing tank 1 can be effectively utilized.

[0040] In addition, if Figure 1 As shown, the detergent tank 15 is configured so that when the cleaning tank 1 is pulled forward by at least a distance a ( Figure 1 In the state above the dotted arrow (shown in FIG. 1 ), the detergent tank 15 can be freely pulled out and pushed in from the detergent tank storage section 14 in the left and right directions. In addition, the distance a represents the shortest distance between the back surface of the door body 3 and the frontmost interface of the housing 2 and the surface of the detergent tank storage section 14 on the side of the washing tank 1. That is, the distance a represents the state in which at least the detergent tank storage section 14 is pulled out as a whole to a position closer to the front side than the frontmost part of the housing 2.

[0041] According to the above structure, when the cleaning tank 1 is completely stored in the housing 2, the detergent tank 15 will not be conspicuous. Therefore, the dishwashing machine can be constructed with a simple design. Moreover, the detergent tank 15 can be pulled out and pushed in only when the cleaning tank 1 is pulled out forward by more than a predetermined distance (distance a). Therefore, the user can easily pull out and push in the detergent tank 15 by using the space in front of the cleaning tank 1 for storing the detergent tank 15 and the space on the side when the cleaning tank 1 is pulled out from the housing 2. In addition, the distance a is not particularly limited as long as it is a distance that allows the detergent tank 15 to be pulled out and pushed in in the left-right direction.

[0042] In addition, as described above, the dishwasher of Embodiment 1 has the operating unit 24, which is provided at the upper front portion outside the washing tank 1 and is used by the user to set the washing program, turn the power on and off, etc. Thus, the user can operate the operating unit 24 with one hand, for example, from the upper front portion of the washing tank 1. At this time, the user can simultaneously pull out and push in the detergent tank 15 in the left and right directions with the other hand. As a result, the user's operability can be improved.

[0043] In addition, the detergent tank 15 is composed of a container such as a bottle for storing liquid detergent. Specifically, the detergent tank 15 includes a detergent tank detergent discharge port 15c, a detergent tank detergent suction path 15d, a detergent containing cover 15e, and the like.

[0044] The detergent tank detergent discharge port 15c, the detergent tank detergent suction path 15d, and the detergent containing cover 15e are integrally formed and configured to be detachable relative to the detergent tank 15. Therefore, when the detergent containing cover 15e is removed from the detergent tank 15, the detergent tank detergent discharge port 15c and the detergent tank detergent suction path 15d, which are integrally formed, can also be removed from the detergent tank 15 at the same time. In addition, the top end of the detergent tank detergent suction path 15d for sucking liquid detergent extends to the vicinity of the bottom surface of the detergent tank 15. Thus, the liquid detergent can be sucked from the detergent tank 15 until it is almost no longer present. Therefore, the liquid detergent in the detergent tank 15 can be used efficiently without waste.

[0045] When the user replenishes liquid detergent into detergent tank 15, the user first removes detergent tank 15 from detergent tank storage portion 14. Then, the user removes detergent containing cover 15e from detergent tank 15. Thus, the user can easily replenish detergent tank 15 with liquid detergent.

[0046] According to the structure of the detergent tank 15 described above, liquid detergent can be supplied to and stored in the detergent tank 15 outside the cleaning tank 1. Therefore, it is possible to suppress the solidification of the detergent in the detergent tank 15 due to moisture, dryness, etc. in the cleaning tank 1 during cleaning. In addition, the volume of the cleaning tank 1 can be increased accordingly compared to when the detergent tank 15 is not configured. And the user can easily load and unload the detergent tank 15. That is, in the past, a substrate for controlling the operation unit, the display unit, etc. was configured between the cleaning tank and the door body, and the space outside the substrate was a dead zone. Therefore, in the present embodiment, the detergent tank 15 is configured in parallel with the substrate in the left-right direction in the dead zone. As a result, the dead zone is effectively utilized, and compared with the previous cleaning tank, the volume of the cleaning tank 1 can be increased accordingly compared to when the detergent tank 15 is not configured in the cleaning tank 1.

[0047] In addition, if Figure 2 As shown, the detergent tank detergent outlet 15c of the detergent tank 15 has a convex portion 15f protruding convexly from the detergent containing cover 15e to the left side. On the other hand, the detergent tank storage portion 14 has a concave portion 14c for engaging the convex portion 15f of the detergent tank detergent outlet 15c. In addition, the concave portion 14c of the detergent tank storage portion 14 engages with the convex portion 15f of the detergent containing cover 15e. Thus, the storage of the detergent tank 15 in the detergent tank storage portion 14 is completed.

[0048] In addition, when the detergent tank 15 is accommodated in the detergent tank storage section 14 by the engagement of the concave section 14c and the convex section 15f, a path for transferring liquid detergent from the detergent tank detergent discharge port 15c to the detergent tank storage section side detergent discharge path 14b is formed. Furthermore, by the engagement of the convex section 15f and the concave section 14c, the detergent tank 15 can be stably accommodated in the detergent tank storage section 14.

[0049] In addition, the detergent tank storage section 14 is provided with a detergent tank storage section detergent outlet 14a provided in the recessed portion 14c. One end of a detergent tank storage section side detergent outlet path 14b is arranged and connected to the detergent tank storage section detergent outlet 14a. On the other hand, a detergent pump 16 is connected to the other end of the detergent tank storage section side detergent outlet path 14b. Furthermore, a detergent pump 16 is connected to a detergent tank detergent outlet 17 (see FIG. 1 ) provided on the front surface of the cleaning tank 1. Figure 1) is connected to the washing tank side detergent discharge path 18. That is, the detergent pump 16 is arranged between the other end of the detergent tank storage portion side detergent discharge path 14b and the washing tank side detergent discharge path 18, that is, in the middle of the detergent input path.

[0050] As described above, the detergent tank 15 has a detergent tank detergent discharge port 15c for discharging liquid detergent in the detergent tank storage portion side detergent discharge path 14b. In addition, the detergent tank storage portion side detergent discharge path 14b is connected to the detergent tank storage portion 14. In other words, when the detergent tank 15 is stored in the detergent tank storage portion 14, the detergent tank detergent discharge port 15c is connected to the detergent tank storage portion side detergent discharge path 14b.

[0051] In addition, if Figure 1 As shown, the control device 19 is disposed below the front surface of the washing tank 1. The control device 19 is used to control the driving of the circulation pump 9, the drainage pump, the water supply pump (water supply valve), the detergent pump 16, etc., for example.

[0052] Specifically, the control device 19 is used to control the driving rotation speed, driving time, etc. of the detergent pump 16. Thus, when washing the tableware 8 and the like, a required amount of liquid detergent is sucked from the detergent tank 15. The sucked liquid detergent is sequentially supplied to the washing tank 1 via the detergent tank detergent suction path 15d, the detergent tank detergent discharge port 15c, the detergent tank storage portion detergent discharge port 14a, the detergent tank storage portion side detergent discharge path 14b, the detergent pump 16, the washing tank side detergent discharge path 18, and the washing tank detergent discharge port 17. That is, it is configured so that the liquid detergent stored in the detergent tank 15 can be transferred and supplied to the washing tank 1.

[0053] The periphery of detergent tank 15 of the dishwasher is configured as described above to supply liquid detergent into washing tub 1 .

[0054] The following reference Figure 4 The structure of the dishwasher in another example of the first embodiment will be described.

[0055] Figure 4 This is a schematic side view of another example of the dishwasher in the state where washing tank 1 is pulled out from housing 2 in Embodiment 1.

[0056] like Figure 4As shown, another example of a dishwasher has a transparent portion 15a provided at least partially on the side of the detergent tank 15. The transparent portion 15a is provided so that when the detergent tank 15 is stored in the detergent tank storage portion 14, the user can visually check the remaining amount of liquid detergent in the detergent tank 15 with the help of the transparent portion 15a. The transparent portion 15a also has a scale 15b for indicating the amount of detergent in the liquid detergent. Thus, even when the detergent tank 15 is stored in the detergent tank storage portion 14, the user can visually check the amount of detergent in the detergent tank 15 from the side with the help of the transparent portion 15a. Therefore, the user can infer the consumption of the liquid detergent, the timing of replenishment, etc. by visual inspection. As a result, the user can pull out the detergent tank 15 and easily replenish the liquid detergent at an appropriate time.

[0057] (Implementation Method 2)

[0058] The following reference Figure 5 and Figure 6 A schematic structure of a dishwasher according to a second embodiment will be described.

[0059] Figure 5 It is a schematic front view of the dishwasher in the state where detergent tank 15 is accommodated in Embodiment 2. Figure 6 This is a schematic side view of the dishwasher in the second embodiment in a state where washing tank 1 is pulled out from housing 2 .

[0060] like Figure 5 and Figure 6 As shown, the dishwasher of Embodiment 2 is different from Embodiment 1 in the arrangement positions of operation unit 24 and display unit 25 and the structure of handle 4. The other structures are the same as those of Embodiment 1, and thus the description of the duplicate structures is omitted.

[0061] That is to say, Figure 5 As shown, in the dishwasher of the second embodiment, the operation unit 24 and the display unit 25 are arranged on the upper front surface of the door body 3. The handle 4 is formed in a shape that is recessed toward the inner side of the door body 3. The operation unit 24 is the same as that of the first embodiment, and the washing program and the power supply are set by the user. The display unit 25 is used to display the washing status, operation status, time, etc.

[0062] The operation unit 24 and the display unit 25 of the second embodiment are arranged on the front side of the door body 3 at the upper front portion outside the washing tank 1. Thus, as in the first embodiment, the user can operate the operation unit 24 from the upper front portion of the washing tank 1 while, for example, pulling out and pushing in the detergent tank storage unit 14 from the left and right directions at the same time.

[0063] In addition, if Figure 6As shown, either the operation unit 24 or the display unit 25 may be disposed on the plane portion 23 as in the first embodiment, and the other of the display unit 25 or the operation unit 24 may be disposed on the upper front surface of the door 3 .

Moreover, the user can easily put in the detergent by loading and unloading the detergent tank.

[0066] In addition, the dishwasher of the present invention is preferably configured such that, when the washing tank is pulled forward by more than a predetermined distance, the detergent tank can be freely pulled out and pushed in relative to the washing tank in the left and right directions. Thus, when the washing tank is completely stored in the housing, the detergent tank will not be conspicuous. Therefore, the dishwasher can be configured with a simple design. On the other hand, the user can only pull out and push in the detergent tank when the washing tank is pulled forward by more than a predetermined distance. Therefore, the detergent tank can be easily pulled out and pushed in by utilizing the space in front of the washing tank for storing the detergent tank and the side space when the washing tank is pulled out from the housing.

[0067] In addition, the dishwasher of the present invention is preferably configured to further include a detergent tank storage portion for storing a detergent tank in the front of the outer side of the washing tank. Thus, when the washing tank is completely stored in the housing, the detergent tank will not be conspicuous. Therefore, the dishwasher can be configured with a simple design. Moreover, the space for storing the detergent tank in the front of the outer side of the washing tank can be effectively utilized. For example, a substrate for an operating unit and a main substrate for control can be stored next to the detergent tank as in the past.

[0068] In addition, the dishwasher of the present invention is preferably configured to further include a transparent portion, and when the detergent tank is stored in the detergent tank storage portion, the user can visually check the side of the detergent tank through the transparent portion, and the transparent portion has a scale for indicating the amount of detergent. Thus, even when the detergent tank is stored in the detergent tank storage portion, the user can easily confirm the amount of detergent in the detergent tank by visual inspection.

[0069] In addition, the detergent tank of the dishwasher of the present invention further comprises a detergent discharge port for discharging liquid detergent to a detergent discharge path. The detergent discharge path is connected to the detergent tank storage portion, and the detergent discharge port is configured such that when the detergent tank is stored in the detergent tank storage portion, the detergent discharge port is connected to the detergent discharge path. Thus, when the detergent tank is stored in the detergent tank storage portion, a path for transferring liquid detergent from the detergent discharge port to the detergent discharge path can be ensured.

[0070] In addition, the dishwasher of the present invention further comprises a detergent pump for transferring the liquid detergent stored in the detergent tank to the washing tank. Thus, the liquid detergent stored in the detergent tank can be sucked by the detergent pump and transferred to the washing tank. At this time, by controlling the driving time of the detergent pump, the liquid detergent in the washing tank can be transferred to the washing tank in an amount required for washing.

[0071] In addition, the dishwasher of the present invention is preferably configured such that the detergent pump is disposed in the middle of the detergent discharge path, so that the liquid detergent stored in the detergent tank can be sucked by the detergent pump and transferred to the washing tank through the detergent discharge path.
