Description

Technical Field

[0001] The present invention belongs to the technical field of washing machines, and in particular, relates to a detergent dispensing device and a washing machine. Background Art

[0002] With the advancement of technology, existing fully automatic washing machines have gradually appeared with automatic detergent dispensing functions. The working principle is roughly to place the detergent in a liquid storage box in advance. After the outlet of the liquid storage box is connected to the water box docking valve, the detergent is drawn into the water box for dilution, and then put into the inner barrel of the washing machine for washing.

[0003] The existing detergent dispensing device is connected to the detergent dispensing waterway through the water inlet waterway. When washing, the detergent dispensed therein is mixed in the water inlet waterway and flushed into the washing machine. However, the water inlet end of the water inlet waterway is externally connected to a tap water pipe, and the water pressure of the water supply therein is variable. When there is no control measure to adjust and control the water pressure, when the water pressure is high, the high-pressure water flow may impact the pipes or control components such as the valve body between the water inlet waterway and the detergent dispensing waterway, causing some components to be broken down and fail, resulting in a malfunction of the detergent dispensing operation and inability to perform subsequent washing operations.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a detergent dispensing device, wherein a connected bypass chamber is provided on a water inlet branch, and an adjusting member is provided between the bypass chamber and the water inlet branch. Under the action of water pressure changes, the adjusting member automatically rotates to change the water flow path of the water inlet branch. The water pressure can be self-regulated by the adjusting member to maintain a stable water pressure, thereby preventing the water pressure of the inlet water flow from being too high and piercing through control devices such as a one-way valve in the water inlet branch and / or the detergent dispensing water channel.

[0006] Another object of the present invention is to provide a washing machine.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: to provide a detergent dispensing device, including a water inlet branch for the flow of water inlet, and also including:

[0008] The bypass chamber is arranged on the water inlet branch and is connected with the water inlet branch;

[0009] The regulating member is rotatably and sealingly arranged on the side wall between the bypass chamber and the water inlet branch. Under the action of the change of water pressure, the regulating member in the bypass chamber is driven to rotate, so as to drive the regulating member in the water inlet branch to rotate and change the water flow path size of the water inlet branch.

[0010] Furthermore, a bypass pipeline is provided on the side wall of the water inlet branch, one end of which is connected to the water inlet branch and the other end of which is connected to the bypass chamber;

[0011] The connecting port between the bypass pipeline and the water inlet branch is located above the connection between the regulating member and the water inlet branch.

[0012] Furthermore, the regulating member located in the bypass chamber includes:

[0013] A rotating part, rotatably connected to the center of the bypass chamber;

[0014] The blocking portion extends along the outer peripheral wall of the rotating portion toward the inner peripheral wall of the bypass chamber until it contacts the inner peripheral wall;

[0015] The inner wall of the bypass chamber is provided with a partition, which extends from the inner wall of the bypass chamber to the outer wall of the rotating part until it contacts the inner wall of the bypass chamber. The blocking part, the partition and the rotating part divide the bypass chamber into a first chamber and a second chamber, and the bypass pipeline is connected to the first chamber.

[0016] Furthermore, the regulating member located in the bypass chamber also includes:

[0017] A mounting portion extending from the outer peripheral wall of the rotating portion to the inner peripheral wall of the bypass cavity, and the mounting portion is located in the second cavity;

[0018] A spring is arranged between the mounting portion and the inner peripheral wall of the bypass chamber, for providing a restoring force for the rotation of the rotating portion.

[0019] Furthermore, a stopper is provided in the region of the bypass chamber corresponding to the blocking portion and the mounting portion, and the stopper extends from a connection with the inner wall of the bypass chamber toward a center of the bypass chamber;

[0020] Preferably, the extension length of the stopper portion is greater than the gap between the mounting portion and the inner wall of the bypass chamber.

[0021] Furthermore, the regulating member located in the water inlet branch extends transversely from the end surface of the regulating member located in the bypass chamber toward the water inlet branch and blocks the entire passage of the water inlet branch;

[0022] The regulating member located in the water inlet branch is provided with a water hole for connecting with the water inlet branch.

[0023] Furthermore, a rotating groove coaxial with the bypass chamber is provided in the water inlet branch, and the rotating groove is communicated with the interior of the water inlet branch;

[0024] The regulating member located in the water inlet branch contacts the rotating groove surface.

[0025] Furthermore, an adjusting component is arranged on the outside of the water inlet branch, and the adjusting component extends into the interior of the bypass cavity and abuts against the spring, so as to adjust the expansion and contraction amount of the spring.

[0026] Further, the regulating component comprises,

[0027] A connecting pipe passes through the interior of the bypass chamber, and the connecting pipe and the spring are on the same axis;

[0028] The adjusting rod is connected with the connecting pipe by sliding or threading, and one end of the adjusting rod abuts against the end of the spring.

[0029] The present invention also provides a washing machine, comprising an external water pipe, wherein any of the above-mentioned detergent dispensing devices also comprises a water mixing branch and a water outlet branch, the water inlet branch, the water mixing branch and the water outlet branch are connected in sequence, the water introduced by the water inlet branch and the extracted detergent are mixed in the water mixing branch, and are dispensed into the interior of the washing machine through the external water pipe by the water outlet branch.

[0030] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0031] (1) The present invention provides a bypass cavity connected to the water inlet branch, and an adjusting member is provided between the bypass cavity and the water inlet branch. Under the action of water pressure changes, the adjusting member automatically rotates to change the water flow path of the water inlet branch, and the water pressure can be self-regulated by the adjusting member to maintain a stable water pressure. This prevents the water pressure of the inlet water flow from being too high, which may cause the one-way valve and other control components in the water inlet branch and / or the detergent delivery water path to break through, thereby causing the overall detergent delivery operation to fail and making it impossible to perform subsequent washing operations.

[0032] (2) The present invention provides a blocking portion extending toward the inner wall of the bypass chamber on the outer peripheral wall of the rotating portion, and a partition is provided on the inner wall of the bypass chamber. The partition, the blocking portion, the outer peripheral wall of the rotating portion and the inner wall of the bypass chamber form two mutually isolated chambers. During the water intake process, the water flow can enter the first chamber through the bypass pipeline. When the water pressure changes, the pressure will be transmitted to the rotating portion, pushing the blocking portion to rotate. Then the regulating member provided in the water intake branch rotates to change the water flow path size in the water intake branch.

[0033] (3) The present invention provides a mounting portion on the outer peripheral wall of the rotating portion, the mounting portion is located in the second cavity, and a spring is arranged between the mounting portion and the bypass cavity. During the rotation process when the water pressure increases, the spring stretches or contracts according to the position of the mounting portion. When the water pressure drops, the regulating member needs to be reversed to ensure the water pressure and water flow on the water inlet branch. Under the rebound effect of the spring, the regulating member can be rotated to the initial state.

[0034] (4) The present invention provides an adjustment assembly on the outside of the water inlet branch, including a connecting pipe connected to the bypass chamber and an adjustment rod slidably or threadedly connected to the connecting pipe. The adjustment rod can be adjusted along the expansion and contraction amount of the spring, thereby changing the initial length of the spring. Due to the change in the initial length of the spring, the deflection angle of the blocking part relative to the bypass pipe changes, thereby adapting to different rated water pressure requirements.

DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0046] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0047] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] like Figures 1 to 6 As shown, a detergent dispensing device described in the present invention includes a water inlet branch 1 for the flow of inlet water.

[0049] The detergent dispensing device of the present invention comprises a detergent dispensing waterway and a water inlet branch 1. One end of the water inlet branch 1 is connected to the detergent dispensing waterway, and the water inlet branch 1 is externally connected to a tap water pipe. By supplying tap water to the water inlet branch 1, water is supplied to the interior of the washing machine and / or the detergent dispensed in the detergent dispensing waterway is mixed and rinsed.

[0050] As we all know, the water pressure of the incoming water flow provided by the tap is often unstable. When the water pressure is high, on the one hand, the effect of mixing the incoming water flow and the detergent is inconsistent, which affects the washing effect; on the other hand, when the water pressure of the incoming water flow is too high, it will break through the control devices such as the one-way valve in the water inlet branch 1 and / or the detergent delivery water channel, thereby causing the overall detergent delivery operation to malfunction and making it impossible to perform subsequent washing actions.

[0051] In order to overcome the above-mentioned defects, the present invention provides corresponding improvements:

[0052] It also includes a bypass chamber 4, which is arranged on the water inlet branch 1 and is connected to the water inlet branch 1;

[0053] The adjusting member 7 is rotatably and sealingly arranged on the side wall between the bypass chamber 4 and the water inlet branch 1. Under the action of the change of water pressure, the adjusting member 7 in the bypass chamber 4 is driven to rotate, so as to drive the adjusting member 7 in the water inlet branch 1 to rotate and change the water flow path size of the water inlet branch 1.

[0054] In the present invention, a disc-shaped structure protruding outward is provided on the outside of the water inlet branch 1, and the inside thereof is hollow to form the bypass chamber 4. There is a wall thickness between the bypass chamber 4 and the water inlet branch 1 to isolate the cavities of the two into independent spaces, and there is a connection between the two, so that during the water flow through the water inlet branch 1, water can flow into the bypass chamber 4 through the connection.

[0055] A perforation is provided between the wall thickness of the bypass chamber 4 and the water inlet branch 1, and an adjusting member 7 is provided on the perforation for rotational sealing. Then a part of the adjusting member 7 is inside the bypass chamber 4, and the other part is on the water inlet branch 1. For the convenience of subsequent description, they are respectively recorded as the first adjusting member 71 and the second adjusting member 72. When the water pressure changes during the water flow of the water inlet branch 1, especially when the water pressure suddenly increases, since the bypass chamber 4 and the water inlet branch 1 are connected, the water pressure acts on the first adjusting member 71 in the bypass chamber 4. When the first adjusting member 71 is driven to rotate, the second adjusting member 72 rotates accordingly, which can change the water flow path size of the water inlet branch 1. Then the water flow rate entering the rear section of the water inlet branch 1 is reduced, and the overall water pressure is reduced, so that when the water flows to the inside of the washing machine and / or the detergent put into the detergent water channel is mixed and rinsed, the water pressure can be self-regulated by the adjusting member 7 to keep the water pressure stable. This prevents the water pressure of the incoming water flow from being too high, which may cause the water inlet branch 1 and / or the one-way valve and other control components in the detergent delivery water path to break down, thereby causing the overall detergent delivery operation to malfunction and making subsequent washing operations impossible.

[0056] Furthermore, a bypass pipe 6 is provided on the side wall of the water inlet branch 1, one end of which is connected to the water inlet branch 1, and the other end of which is connected to the bypass chamber 4;

[0057] The connecting opening between the bypass pipeline 6 and the water inlet branch 1 is located above the connection between the regulating member 7 and the water inlet branch 1 .

[0058] In the present invention, a bypass pipe 6 is provided on the side wall of the water inlet branch 1, and the inside of the water inlet branch 1 is connected with the inside of the bypass chamber 4. The water inlet branch 1 may include two detachable parts, front and rear, and water tanks are provided on the opposite side walls, and the two parts are relatively spliced, so that the water tanks are butted to form the bypass pipe 6. The water inlet branch 1 is formed into the bypass pipe 6 by splicing, which is convenient for rapid internal molding.

[0059] Reference Figure 1The water inlet branch 1 is located below the detergent dispensing device, and extends vertically upward to communicate with the mixing branch of the detergent dispensing device (which will be described in detail in the subsequent embodiments), so that the inlet water flows from the water inlet branch 1 located below to the mixing branch. In addition, since the water inlet branch 1 is connected to the bypass chamber 4 through the bypass pipe 6, the inlet water flow will also fill the bypass chamber 4. The inlet water flows from the upper end of the bypass pipe 6 to the inside of the bypass chamber 4. When the water pressure suddenly changes, its pressure will be transmitted to cause the adjustment member 7 inside the bypass chamber 4 to rotate. Since the rotation of the first adjusting member 71 will drive the second adjusting member 72 to rotate accordingly, thereby changing the water flow path size of the water inlet branch 1, the water flow rate is reduced and the water pressure is lowered, so that the adjusting member 7 can self-adjust the water pressure change of the water inlet branch 1, and ensure that the water with a stable and safe water pressure flows through the water inlet branch 1 to the mixing water branch 2, avoiding the breakdown of the control components such as the one-way valve in the water inlet branch 1 and / or the detergent delivery water channel, thereby causing the overall detergent delivery operation to malfunction and making it impossible to perform subsequent washing actions.

[0060] Furthermore, the regulating member 7 located in the bypass chamber 4 includes:

[0061] The rotating part 711 is rotatably connected to the center of the bypass chamber 4;

[0062] The blocking portion 712 extends along the outer peripheral wall of the rotating portion 711 toward the inner peripheral wall of the bypass chamber 4 until it contacts the inner peripheral wall;

[0063] The inner wall of the bypass chamber 4 is provided with a partition, which extends from the inner wall of the bypass chamber 4 to the outer wall of the rotating part 711 until it contacts the inner wall. The blocking part 712, the partition and the rotating part 711 divide the bypass chamber 4 into a first chamber and a second chamber, and the bypass pipeline 6 is connected to the first chamber.

[0064] In the present invention, the first adjusting member 71 includes a rotating portion 711 and a blocking portion 712. The rotating portion 711 is connected in a rotating sealing manner on the perforation on the wall thickness between the bypass chamber 4 and the water inlet branch 1. The longitudinal section of the bypass chamber 4 is circular, wherein the rotating portion 711 matches the longitudinal section shape of the bypass chamber 4, and there is a gap between the outer peripheral wall of the rotating portion 711 and the inner wall of the bypass chamber 4. The outer peripheral wall of the rotating portion 711 is provided with a blocking portion 712 extending toward the inner wall of the bypass chamber 4, and the extended end of the blocking portion 712 is in contact with the inner wall of the bypass chamber 4. In order to ensure sealing, a sealing strip is provided on the side wall of the extended end of the blocking portion 712. A partition is provided on the inner wall of the bypass chamber 4, wherein the preferred partition extends horizontally to the outer peripheral wall of the rotating portion 711 and contacts its outer wall. Similarly, in order to ensure sealing performance, a sealing strip is provided at the extended end of the partition. Through the above arrangement, the partition, the blocking portion 712, the outer peripheral wall of the rotating portion 711 and the inner wall of the bypass chamber 4 form two mutually isolated chambers, which are respectively recorded as the first chamber and the second chamber. The first chamber is connected to the inside of the water inlet branch 1 through the bypass pipe 6.

[0065] During the water intake process, the water flow can enter the first chamber through the bypass pipe 6. When the water pressure changes, the pressure will be transmitted to the rotating part 711, pushing the blocking part 712 to rotate. Then the adjusting member 7 arranged in the water intake branch 1 rotates to change the water flow path size in the water intake branch 1. By adjusting the water intake amount, the water pressure of the water intake is reduced, so as to avoid the breakdown of the control components such as the one-way valve in the water intake branch 1 and / or the detergent delivery water path, thereby causing the overall detergent delivery operation to fail and the subsequent washing action cannot be performed.

[0066] Furthermore, the adjusting member 7 located in the bypass chamber 4 further includes:

[0067] The mounting portion 713 extends from the outer peripheral wall of the rotating portion 711 to the inner peripheral wall of the bypass chamber 4, and the mounting portion 713 is located in the second cavity;

[0068] A spring 8 is provided between the mounting portion 713 and the inner peripheral wall of the bypass chamber 4 to provide a restoring force for the rotating portion 711 to rotate.

[0069] In the present invention, the first adjusting member 71 further includes a mounting portion 713 disposed on the outer peripheral wall of the rotating portion 711, and the mounting portion 713 is located in the second cavity. The mounting portion 713 extends along the radial direction of the rotating portion 711 toward the inner wall close to the bypass cavity 4, and a spring 8 is disposed between the mounting portion 713 and the bypass cavity 4. When the first adjusting member 71 rotates when the water pressure increases, the spring 8 stretches or contracts according to the position of the mounting portion 713. When the water pressure drops, the first adjusting member 71 needs to be reversed to ensure the water pressure and water flow on the water inlet branch 1. Under the rebound effect of the spring 8, the adjusting member 7 can be rotated to the initial state.

[0070] Furthermore, a stopper 9 is provided in the area of ​​the bypass chamber 4 corresponding to the blocking portion 712 and the mounting portion 713, and the stopper 9 extends from the connection with the inner wall of the bypass chamber 4 to the center of the bypass chamber 4;

[0071] Preferably, the extension length of the stopper portion 9 is greater than the gap between the mounting portion 713 and the inner wall of the bypass chamber 4 .

[0072] In the present invention, a stopper 9 is provided on the inner wall of the accommodating chamber of the second chamber, and the stopper 9 can be counteracted with the mounting portion 713 on the rotation path of the rotating portion 711. That is, the extension length of the stopper 9 is greater than the gap between the mounting portion 713 and the inner wall of the bypass chamber 4. During the rotation of the rotating portion 711, the blocking portion 712 is prevented from rotating at an excessive angle, exceeding the bypass pipeline 6 or just blocking the bypass pipeline 6, thereby preventing the rotating portion 711 from changing its rotation direction, which may increase the water flow path of the water inlet branch 1 and further increase the water pressure.

[0073] Another preferred embodiment: In order to prevent the rotation direction of the rotating part 711 from changing, a torsion spring can be provided on the rotating part 711. Through the rotation characteristics of the torsion spring, on the one hand, a rotation elastic force for resetting the rotating part 711 can be provided, and on the other hand, the rotating part 711 will no longer rotate after rotating to the initial state.

[0074] Furthermore, the regulating member 7 located in the water inlet branch 1 extends transversely from the end surface of the regulating member 7 located in the bypass chamber 4 toward the water inlet branch 1 and blocks the entire passage of the water inlet branch 1;

[0075] The regulating member 7 located in the water inlet branch 1 is provided with a water hole 721 for connecting with the water inlet branch 1 .

[0076] In the present invention, one end of the second adjusting member 72 is coaxially connected to the end of the rotating part 711 in the first adjusting member 71, and the other end of the second adjusting member 72 extends horizontally to the passage of the entire water inlet branch 1, and the inner side wall of the water inlet branch 1 is contacted by the outer peripheral wall of the second adjusting member 72 to achieve the blocking of the inside of the water inlet branch 1. A water hole 721 is provided on the second adjusting member 72, wherein the water hole 721 can connect the water inlet branch 1 at the upper and lower ends of the second adjusting member 72. In the process that the second adjusting member 72 rotates with the first adjusting member 71, the water flow path of the water hole 721 in the water inlet branch 1 can change. That is, when the water hole 721 in the second adjusting member 72 coincides with or contacts the inner wall of the water inlet branch 1 during rotation, the water flow path of the water hole 721 is reduced, which plays a role in reducing the water flow and lowering the water pressure.

[0077] Furthermore, a rotating groove coaxial with the bypass chamber 4 is provided in the water inlet branch 1, and the rotating groove is communicated with the interior of the water inlet branch 1;

[0078] The regulating member 7 located in the water inlet branch 1 contacts the rotating groove surface.

[0079] In the present invention, a rotating groove matching the shape of the second adjusting member 72 is provided inside the water inlet branch 1. The second adjusting member 72 is preferably a columnar structure, and the cross section of the rotating groove is circular. The second adjusting member 72 is in the rotating groove, so that the two are in surface contact, thereby ensuring that the second adjusting member 72 and the water inlet branch 1 are sealed on the relative surface, and no water leakage occurs, so that the inlet water flow can only pass through the water hole 721. This ensures that the second adjusting member 72 can adjust the water pressure more accurately.

[0080] Furthermore, an adjusting component 5 is provided on the outside of the water inlet branch 1 . The adjusting component 5 extends into the inside of the bypass chamber 4 and abuts against the spring 8 , so as to adjust the expansion and contraction amount of the spring 8 .

[0081] In the present invention, in correspondence with different washing machines or different washing programs in the washing machine, the requirements for the water flow rate per unit time are also different, that is, the rated water pressure passing through is different. Therefore, corresponding to the second adjusting member 72 and the water inlet branch 1 in the initial state, the opening size of the water flow path of the water hole 721 needs to be adjusted. Specifically, an adjusting component 5 is provided on the outside of the water inlet branch 1, and the adjusting part of the adjusting component 5 can be adjusted along the expansion and contraction amount of the spring 8, thereby changing the initial length of the spring 8. Furthermore, due to the change in the initial length of the spring 8, the deflection angle of the blocking portion 712 relative to the bypass line 6 changes, which can adapt to the requirements of different rated water pressures.

[0082] Further, the adjustment component 5 includes,

[0083] The connecting pipe 51 passes through the interior of the bypass chamber 4, and the connecting pipe 51 and the spring 8 are on the same axis;

[0084] The adjusting rod 52 is slidably or threadedly connected to the connecting pipe 51 , and one end of the adjusting rod 52 abuts against the end of the spring 8 .

[0085] In the present invention, the connecting pipe 51 in the adjusting assembly 5 is connected to the bypass chamber 4, and the direction of the outward extension is on the same axis as the spring 8. The connecting pipe 51 is provided with an adjusting rod 52, which can slide or be threadedly connected with the inner wall of the connecting pipe 51, and the adjusting rod 52 extends into the bypass chamber 4 to abut or connect with the end of the spring 8. The preferred threaded connection between the adjusting rod 52 and the connecting pipe 51 can ensure the sealing of the bypass chamber 4, and the adjusting rod 52 can be more stably maintained at the preset position after adjustment.

[0086] The present invention also provides a washing machine, comprising an external water pipe, wherein any of the above-mentioned detergent dispensing devices also comprises a water mixing branch 2 and a water outlet branch 3, wherein the water inlet branch 1, the water mixing branch 2 and the water outlet branch 3 are connected in sequence, and the water introduced by the water inlet branch 1 and the extracted detergent are mixed in the water mixing branch 2 and dispensed into the washing machine through the external water pipe by the water outlet branch 3.

[0087] In the present invention, the detergent delivery device includes a water inlet branch 1, a water mixing branch 2 and a water outlet branch 3, wherein the water inlet branch 1 and the water outlet branch 3 are respectively connected vertically to the two ends of the water mixing branch 2. Among them, the water outlet branch 3 is connected to the external water pipe in the washing machine. The water mixing branch 2 is connected to each detergent delivery waterway, and a one-way valve is provided at the connection point. In order to avoid the water pressure of the inlet water flow in the water inlet branch 1 being too high and entering the water mixing branch 2, causing the one-way valve and other control devices in the water inlet branch 1 and / or the detergent delivery waterway to be broken. Then, an adjusting member 7 is provided in the water inlet waterway, and the adjusting member 7 is driven to rotate by the change of water pressure to change the size of the water flow path of the water inlet waterway, so as to achieve the effect of adjusting the water pressure, thereby ensuring that the overall detergent delivery operation will not fail, so that the mixed liquid can be delivered to the inside of the washing machine through the external water pipe, and then the subsequent washing action is completed.

[0088] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
