It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0041] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0042] Please see Figure 1 and Figure 2 As shown, this application embodiment provides a household appliance 100, which includes a cylindrical body 1 and a condenser assembly 2. The cylindrical body 1 forms a receiving space (not shown) for accommodating objects, and an opening (not shown) communicating with the receiving space is provided on one axial side of the cylindrical body 1, which is also equivalent to the opening of the receiving space. A drying air duct 10 is provided on the other axial side of the cylindrical body 1, and the drying air duct 10 can communicate with the receiving space; the condenser assembly 2 is disposed in the drying air duct 10.

[0043] When the condenser assembly 2 is installed in the drying duct 10, it is used to condense and dehumidify the humid and hot air in the drying duct 10. Specifically, the humid and hot air generated in the containment space can enter the drying duct 10, and after being condensed and dehumidified by the condenser assembly 2, it becomes low-humidity air, which is then recirculated into the containment space and carries away the moisture on the objects inside.

[0044] The specific type of the household appliance 100 is not limited.

[0045] In one embodiment, the household appliance 100 is a washer-dryer combo. In this case, the drum body 1 is fixedly installed, and the condenser assembly 2 is fixedly installed relative to the drum body 1. Specifically, the drying air duct 10 may be formed at least on the opposite axial surface of the drum body 1. Typically, the household appliance 100 also includes a housing (not shown), within which the drum body 1 and the condenser assembly 2 are integrally arranged. Furthermore, the household appliance 100 also includes an inner drum (not shown), located within the receiving space of the aforementioned drum body 1 (the drum body 1 is essentially the outer drum). The drum body 1 is fixedly installed within the housing, and the inner drum is rotatably installed within the receiving space of the drum body 1. The rotation center line of the inner drum can be considered as the central axis of the drum body 1.

[0046] The interior of the inner drum forms a space for handling clothes. The drum body 1 provides certain support for the inner drum, which can withstand the various forces generated by the inner drum during washing, spin-drying and drying, ensuring that the inner drum can operate normally, while maintaining the overall structural stability of the household appliance 100, preventing the inner drum from shaking, shifting or even being damaged due to uneven force.

[0047] When the household appliance 100 is in washing mode, the containment space can store washing water. During the washing and rinsing process, the drum 1 is responsible for storing an appropriate amount of water to provide a washing and rinsing environment for the clothes in the inner drum.

[0048] When the household appliance 100 is in drying mode, the refrigerant flows into the condenser assembly 2, giving the condenser assembly 2 a lower temperature. At this time, the hot and humid air from the clothes handling space enters the drying duct 10 through the containment space, where it is condensed by the condenser assembly 2. The condensed, low-humidity air then returns to the clothes handling space and further removes moisture from the clothes.

[0049] Please see Figure 1 and Figure 2 As shown, the drying duct 10 can be composed of a side plate 101 disposed on the opposite side of the cylinder 1 along its axial direction and a sealing plate (not shown). The side plate 101 is generally annular, and the sealing plate is connected to the end face of the side plate 101 facing away from the cylinder 1. The side plate 101 can be integrally formed with the cylinder 1. However, this is not a limitation; in other alternative embodiments, the drying duct 10 can have other configurations.

[0050] The drying air duct 10 is connected to the accommodating space through the second inlet 102 and the second outlet 103, such as... Figure 1 and Figure 2 As shown.

[0051] Please see Figure 3As shown, in one embodiment, the household appliance 100 further includes a filter assembly and a spray assembly 3. The filter assembly is disposed within the drying duct 10, dividing the drying duct 10 into at least a first space and a second space along the airflow direction (the direction of flow of humid and hot air). A condenser assembly 2 is disposed within the second space, and the spray assembly 3 is disposed within the second space, with the condenser assembly 2 located between the cylinder 1 and the spray assembly 3. The purpose of this arrangement is that the filter assembly is located upstream of the condenser assembly 2, which can collect foreign matter such as lint mixed inside the humid and hot air. The condenser assembly 2 is located between the cylinder 1 and the spray assembly 3, and the spray assembly 3 can spray water towards the filter assembly, that is, away from the condenser assembly 2, to reverse-wash the foreign matter such as lint adsorbed on the filter assembly. The washed foreign matter can be discharged with the water through the drain section, the receiving space of the cylinder 1, and the drain pipe.

[0052] For example, the spray assembly 3 is inclined from top to bottom in the drying air duct 10, and the distance between the upper part of the spray assembly 3 and the outer cylinder is greater than the distance between the lower part of the spray assembly and the outer cylinder.

[0053] Understandably, due to the presence of the spray assembly 3, the second space is relatively narrow in the axial direction of the cylinder 1. The condensation assembly 2 of this application can be placed vertically between the duct wall of the drying duct 10 and the spray assembly 3 to maximize the use of the narrow space and improve heat exchange efficiency.

[0054] The filter assembly includes a mounting bracket 4 and a filter element (not shown). The mounting bracket 4 is disposed within the drying air duct 10 and located on the side of the spray assembly 3 opposite to the condenser assembly 2. The filter element is mounted on the mounting bracket 4. The filter element can be one or more layers of filter mesh.

[0055] In this embodiment, the shape of the accommodating space of the cylinder 1 is not limited; it can be a circular space or a square space, for example, a circular space, to accommodate the rotating inner cylinder. The space inside the inner cylinder can be a circular space.

[0056] In one embodiment, the household appliance 100 is a clothes dryer. In this case, the drum 1 is rotatably mounted inside the casing about its central axis, and an inner drum is not required. The accommodating space of the drum 1 is used to hold the clothes to be dried, and the drum 1 can rotate with the clothes to be dried, so that the low-humidity air can fully contact the clothes and remove the moisture from the clothes. In this embodiment, the accommodating space of the drum 1 can be a circular space to facilitate the effective circulation and rolling of the clothes inside.

[0057] In this configuration, the drying duct 10 and the cylinder 1 are independently configured; that is, the drying duct 10 is enclosed and defined by other structures outside the cylinder 1. The condenser assembly 2 is fixedly installed together with the drying duct 10. During the rotation of the cylinder 1, the accommodating space remains in constant communication with the drying duct 10.

[0058] In one embodiment, the household appliance 100 can also be a dishwasher. The accommodating space of the drum 1 is used to accommodate tableware. After the tableware is washed, the air temperature and humidity in the accommodating space are high. At this time, the air in the accommodating space can enter the drying duct 10 and be condensed and dehumidified. After returning to the accommodating space, it can continue to remove moisture from the surface of the tableware. In this embodiment, the drum 1 is fixedly installed. Similarly, the drying duct 10 can be at least partially disposed on the surface of the other side of the axial direction of the drum 1.

[0059] In this embodiment, the accommodating space of the cylinder 1 can be a near-square space, such as a regular space close to a cuboid, which is beneficial for the placement of tableware.

[0060] The following section, using a washer-dryer combo as an example, will provide a detailed explanation of the specific structure of the condenser assembly 2 and its use in the household appliance 100.

[0061] It is understood that the household appliance 100 provided in this application embodiment has a specific orientation during use. For example, the rotation center axis of the inner cylinder is generally horizontal or horizontal. Based on this, for ease of description and understanding, the terms "upper," "lower," "front," and "rear" used in the accompanying drawings and the following description are all based on the orientation of the user when using the household appliance 100. The side of the household appliance 100 facing the user is front, the side away from the user is rear, the side closer to the ground is lower, and the side away from the ground is upper.

[0062] In an embodiment where the condenser assembly 2 is installed in the drying duct of the household appliance 100, the condenser assembly 2 is located on the rear side of the cylinder 1.

[0063] The specific substance of the refrigerant is not limited. For example, the refrigerant can be water, specifically low-temperature water; or, the refrigerant can be low-temperature air; or, the refrigerant can be other low-temperature organic substances. The following explanation uses low-temperature water as an example of a refrigerant.

[0064] Specifically, such as Figures 4 to 7 As shown, the condenser assembly 2 includes a base plate 21 and a cover plate 22 disposed opposite to each other, forming a flat space 20 for refrigerant flow between the base plate 21 and the cover plate 22. Please refer to the reference. Figure 6 and Figure 7 As shown. Please refer to the following: Figure 2 As shown, the bottom plate 21 is located on the other side of the cylinder 1 along the axial direction, and the cover plate 22 is located on the side of the bottom plate 21 away from the cylinder 1 along the axial direction. The bottom plate 21 and the cover plate 22 are arranged opposite each other along the front and rear direction of the cylinder 1.

[0065] The condensing assembly 2 provided in this application embodiment includes a bottom plate 21 disposed on the other side of the cylinder 1 along the axial direction, and a cover plate 22 disposed on the side of the bottom plate 21 away from the cylinder 1 along the axial direction. A flat space 20 for refrigerant flow is formed between the bottom plate 21 and the cover plate 22. Thus, the condensing assembly 2 is generally flat and has a small thickness in the front-back direction, making it suitable for use in flat spaces, such as the space between the spray assembly 3 and the other side of the surface of the cylinder 1 along the axial direction.

[0066] In the household appliance 100, the cylinder 1 has a certain radial area. Therefore, the flat condenser assembly 2 is suitable for use in the flat space on the other side of the cylinder 1 along the axial direction. It can be adapted to the axial end face of the cylinder 1 and has a large inner surface for heat exchange with the refrigerant. The condenser assembly 2 has a small volume and a large heat exchange area. Furthermore, the household appliance 100 using the condenser assembly 2 can also have a small thickness and volume.

[0067] It should be noted that the condenser assembly 2 is arranged vertically within the drying duct 10. The purpose of this arrangement is that the drying duct 10 is the area with the largest airflow and the highest temperature and humidity in the household appliance. The condenser assembly 2 is arranged roughly parallel to the airflow direction of the hot and humid air within the drying duct 10, allowing the condenser assembly 2 to have the largest contact area and the highest heat exchange efficiency with the hot and humid air.

[0068] Please see Figure 2 , Figure 4 and Figure 5 As shown, a condensation assembly 2 is provided.

[0069] The condenser assembly 2 is also provided with a first inlet 201 and a first outlet 202 communicating with the flat space 20. The first inlet 201 allows refrigerant to flow into the flat space 20, and the first outlet 202 allows refrigerant to flow out of the flat space 20. Figure 6 As shown. In one embodiment, the first inlet 201 is located at the upper end of the flat space 20, and the first outlet 202 is located at the lower end of the flat space 20. Please refer to [link / reference] for details. Figure 6 As shown. That is, in this condensation assembly 2, the refrigerant flows in from the upper end of the flat space 20, flows downward under the action of gravity, and disperses between the bottom plate 21 and the cover plate 22.

[0070] The form of the first inlet 201 and the first outlet 202 is not limited. For example, the first inlet 201 and the first outlet 202 can be set as round holes, or the upper and lower ends of the base plate 21 and the cover plate 22 can be separated by a certain distance to form the first inlet 201 and the first outlet 202.

[0071] Specifically, for easier water intake, please refer to [link / reference]. Figure 2 and Figure 4As shown, a pipe section 213 is provided at the upper end of the base plate 21 and / or cover plate 22. The pipe section 213 communicates with the flat space 20, and the upper end of the pipe section 213 is used to connect to the water inlet pipe 11 (see...). Figure 1 and Figure 2 (As shown). At least a portion of the water inlet pipe 11 can be fixedly disposed on the outer surface of the cylinder 1. Exemplarily, the refrigerant is water, and water is supplied to the condenser assembly 2 through the water inlet pipe 11 when the household appliance 100 starts running the drying program, and the water supply is stopped after the drying program has been running for a period of time or after the program is completed.

[0072] Please see Figure 4 , Figure 5 and Figure 6 As shown, in one embodiment, the lower ends of the base plate 21 and the cover plate 22 are arranged separately to form a first outlet 202 for refrigerant to flow out. In this case, the first outlet 202 has a flat opening style. The purpose of this arrangement is to simplify the structure and reduce the manufacturing cost of the cover plate 22 and the base plate 21.

[0073] It should be noted that the condenser assembly 2 is located inside the drying duct 10, and the first outlet 202 is open. Therefore, after the cooling water flows out from the first outlet 202, it actually enters the drying duct 10. In one embodiment of this application, the drying duct 10 is also provided with a drainage section (not shown) for the cooling water to be discharged. For example, the drainage section is connected to the receiving space and further connected to the drain pipe, so that the water can be discharged through the receiving space and the drain pipe (not shown).

[0074] Based on this, although cooling water will enter the drying air duct 10, by reasonably setting the positions of the second inlet 102 and the second outlet 103, the drainage part is separated from the second outlet 103, and the flow path of the hot and humid air and the flow path of the cooling water do not affect each other, thus preventing the cooling water from entering the second outlet 103.

[0075] For example, one implementation is to place the drain section at the lower end of the drying duct 10, so that the cooling water automatically collects at the drain section under gravity, while the second outlet 103 can be placed at the upper end of the drying duct 10, so that the second outlet 103 is separated from the drain section as much as possible. The position of the second inlet 102 is not too limited, as long as it can ensure that the hot and humid air comes into contact with the condenser 2 as much as possible in the drying duct 10. For example, the second inlet 102 can also be placed at a relatively lower position in the drying duct 10 and spaced apart from the drain section, so as to ensure that the hot and humid air flows from bottom to top over the surface of the condenser 2.

[0076] In this embodiment, cooling water flows from the first inlet 201 to the first outlet 202 under the influence of gravity. To ensure that the cooling water is dispersed as much as possible on the inner surfaces (surfaces facing each other) of the base plate 21 and the cover plate 22, and to improve condensation efficiency, such as... Figure 4 and Figure 7 As shown, the inner surface of the base plate 21 is provided with a plurality of protruding horizontal ribs 211, which are spaced apart in the vertical direction, such as... Figure 6 and Figure 7 As shown, there is a gap 2110 between the horizontal rib 211 and the inner surface of the cover plate 22, and the horizontal width D of the gap 2110 is smaller than the horizontal width L at other locations within the flat space 20. That is to say, the arrangement of the horizontal rib 211 allows the cooling water flowing down from the first inlet 201 to be dispersed on the upper surface of the horizontal rib 211. On the other hand, the smaller size of the gap 2110 between the horizontal rib 211 and the inner surface of the cover plate 22 slows down the speed at which the cooling water flows downward from the horizontal rib 211. Overall, this allows the cooling water to be fully dispersed between the cover plate 22 and the bottom plate 21, and to fully exchange heat with the bottom plate 21 and the cover plate 22.

[0077] The horizontal width D of the gap 2110 is set to be as small as possible while allowing cooling water to pass through. For example, the horizontal width D of the gap 2110 is less than or equal to 1 mm. Optionally, the horizontal width D of the gap 2110 is less than or equal to 0.8 mm; alternatively, the horizontal width D of the gap 2110 is less than or equal to 0.5 mm. In some embodiments, the horizontal width D of the gap 2110 is greater than or equal to 0.3 mm to allow for smooth flow of cooling water.

[0078] Please refer to the following: Figure 4 and Figure 6 As shown, the first inlet 201 is formed on the base plate 21. The purpose of this arrangement is that, in the vertical direction, the first inlet 201 is easily aligned with the horizontal rib 211, so that the cooling water flowing in from the first inlet 201 first reaches the upper surface of the uppermost horizontal rib 211 for dispersion, rather than directly reaching the gap 2110 between the horizontal rib 211 and the cover plate 22.

[0079] In other alternative embodiments, the horizontal rib 211 may be disposed on the inner surface of the cover plate 22. Optionally, the first inlet 201 is formed on the cover plate 22 and may be aligned with the horizontal rib 211 in the vertical direction.

[0080] Alternatively, the horizontal ribs 211 can be formed on both the inner surface of the cover plate 22 and the inner surface of the base plate 21. Specifically, the horizontal ribs 211 on the cover plate 22 and the horizontal ribs 211 on the base plate 21 are aligned horizontally and spaced apart to form a gap 2110. Alternatively, the horizontal ribs 211 on the cover plate 22 and the horizontal ribs 211 on the base plate 21 can be arranged alternately in the vertical direction, so that the flow path of the cooling water in the vertical direction is S-shaped, which is beneficial to further increase the full dispersion of the cooling water in the flat space 20. Optionally, the first inlet 201 can be provided on the base plate 21 and / or the cover plate 22, as long as it can make the cooling water as fully dispersed as possible on the upper surface of the horizontal ribs 211.

[0081] Please refer to the following: Figure 2 As shown, the base plate 21 is positioned close to the cylinder 1, while the cover plate 22 is positioned away from the cylinder 1. Therefore, the outer surface of the cover plate 22 is primarily used for heat exchange with the humid and hot air. Optionally, the cover plate 22 is made of a material with a high thermal conductivity, such as metal. Specifically, the cover plate 22 can be made of aluminum, copper, or steel.

[0082] The base plate 21 can be made of metal or non-metal. For example, if the base plate 21 is made of metal, it can be made of aluminum, copper, or steel. Alternatively, if the base plate 21 is made of non-metal, it can be made of plastic.

[0083] Optionally, the base plate 21 is made of the same material as the cylinder 1. For example, both the base plate 21 and the cylinder 1 are made of plastic.

[0084] Based on this, the aforementioned horizontal ribs 211, pipe segments 213, etc. can all be integrally formed on the base plate 21, without needing to be formed on the cover plate 22, which can simplify the processing cost of the metal cover plate 22.

[0085] Please refer to the following: Figure 5 and Figure 6 As shown, the portion of the cover plate 22 protruding from the bottom of the base plate 21 forms an extension section 223. That is, in the vertical direction, the cover plate 22 has an extension section 223 that protrudes downward relative to the bottom of the base plate 21. The side surface of the extension section 223 facing the base plate 21 is used for the flow of cooling water. By providing the extension section 223, the surface area of ​​the cover plate 22 can be further increased to improve the heat exchange rate between the cover plate 22 and the humid air. Furthermore, by using the small size design of the gap 2110 between the horizontal rib 211 and the cover plate 22, the cooling water can be evenly distributed between the inner surface of the extension section 223 and the rear surface of the cylinder 1 after flowing out of the gap 2110; in addition, the cooling water can flow along the rear surface of the cylinder 1 toward the drain, rather than being suspended relative to the rear surface of the cylinder 1, which can avoid the problem of cooling water splashing or spraying caused by humid air.

[0086] In addition, please see Figure 5 As shown, in one embodiment, the cover plate 22 is provided with a plurality of vertical recesses 221, which are recessed toward the flat space 20 and the bottom plate 21, and the plurality of vertical recesses 221 are distributed at intervals along the horizontal direction. The purpose of this arrangement is that, on the one hand, the arrangement of the vertical recesses 221 can further increase the surface area of ​​the cover plate 22 and increase the heat exchange rate between the cover plate 22 and the humid and hot air; on the other hand, the vertical recesses 221 also serve as reinforcing ribs, which can increase the strength of the cover plate 22 and prevent the cover plate 22 from deforming. Especially when the area of ​​the cover plate 22 is relatively large, it is beneficial to maintain the size of the flat space 20 and the gap 2110 between the cover plate 22 and the bottom plate 21.

[0087] It should be noted here that "concave" and "convex" are relative terms; the portion between the vertical concave areas 221 is the vertical convex area 222 (please refer to the relevant documentation). Figure 5 (As shown). The vertical concave area 221 and the vertical convex area 222 can be formed by pressing a portion of the cover plate 22 in the direction toward the base plate 21, or by pressing a portion of the cover plate 22 away from the base plate 21.

[0088] Of course, the inner surface of the cover plate 22 is also concave-convex to match the surface of the cover plate 22. On this basis, the end face of the horizontal rib 211 of the base plate 21 is concave to match the vertical recess 221. The purpose of this arrangement is to ensure that the horizontal width of the gap 2110 between the horizontal rib 211 and the inner surface of the cover plate 22 is consistent at all points, so as to prevent the cooling water from flowing away from one point in a concentrated manner.

[0089] Please refer to the following: Figure 8 As shown, a condenser assembly 2 with an alternative structure is provided.

[0090] In this embodiment, the first outlet 202 is located at the upper end of the flat space 20. The purpose of this arrangement is to ensure that at least a portion of the cooling water flows from bottom to top and eventually exits from the upper end of the flat space 20, which ensures that the cooling water is fully filled within the flat space 20.

[0091] Regarding the location of the first import 201, as follows: Figure 8 As shown, in one embodiment, a first inlet 201 for refrigerant inflow is located at the upper end of the flat space 20. Figure 8In the pipe section 213, there is a first inlet 201 (not shown here). At least one of the bottom plate 21 and the cover plate 22 has a dividing rib 23 on its inner surface. The dividing rib 23 extends from between the first inlet 201 and the first outlet 202 towards the lower end of the flat space 20. However, the lowermost end of the dividing rib 23 does not completely block the flat space 10; rather, it allows the flat space 10 to remain connected below the dividing rib 23. The purpose of this arrangement is to divide the flat space 20 into two parts: one part is used for cooling water to flow downwards from the first inlet 201 and be stored at the bottom of the flat space 20; the other part is used for the stored cooling water to gradually flow upwards and reach the first outlet 202. Thus, the cooling water can be dispersed as much as possible within the flat space 20.

[0092] In other alternative embodiments, the first inlet 201 may also be located at the lower end of the flat space 20. In this way, the cooling water completely fills the entire flat space 20 from bottom to top.

[0093] In this embodiment, the lower end of the cover plate 22 is also provided with an extension section 223. The extension section 223 allows the refrigerant to flow on its surface after flowing out of the first outlet 202, specifically, it can flow on the surface of the extension section 223 facing the bottom plate 21. Figure 8 As shown, the first outlet 202 is located on the base plate 21. During installation, the condenser assembly 2 has a certain gap between the base plate 21 and the rear surface of the cylinder 1, allowing cooling water to flow from the first outlet 202 down the front surface of the base plate 21 and reach the front surface of the extension section 223. Although the temperature of the cooling water flowing out of the first outlet 202 is slightly increased, it is still relatively low-temperature compared to the humid air, thus allowing the extension section 223 to continue exchanging heat with the humid air.

[0094] As mentioned earlier, when the condenser assembly 2 is located between the spray assembly and the duct wall of the drying duct 10 in the household appliance drying duct, the distance between the upper part of the spray assembly 3 and the outer cylinder (that is, between the spray assembly 3 and the duct wall of the drying duct 10) is greater than the distance between the lower part of the spray assembly 3 and the outer cylinder. At a certain height of the spray assembly 3, the space between the spray assembly 3 and the outer cylinder is too narrow to accommodate the flat space formed by the bottom plate and the cover plate of the condenser assembly 2. In order to make full use of this space for heat exchange, an extension section for heat exchange is provided on the cover plate.

[0095] In one optional embodiment, the cover plate 22 is provided with a plurality of vertical recesses 221, which are recessed toward the flat space 20. The plurality of vertical recesses 221 are spaced apart in the horizontal direction, and the spaces between the vertical recesses 221 serve as vertical convex areas 222. This can also increase the surface area of ​​the cover plate 22 and improve the heat exchange efficiency between the cover plate 22 and the humid air.

[0096] Please see Figure 2 As shown, in one embodiment, a seal 24 is provided between the cover plate 22 and the base plate 21, surrounding the flat space 20 and avoiding the first inlet 201 and the first outlet 202. The purpose of this arrangement is to maintain a sealed connection between the cover plate 22 and the base plate 21 except for the first inlet 201 and the first outlet 202, so that cooling water can only flow in from the first inlet 201 and flow out from the first outlet 202, and will not flow out from other locations, so as to ensure that the cooling water can be completely exchanged with the humid and hot air through the condensation assembly 2.

[0097] The installation method of the seal 24 is not limited. Specifically, the cover plate 22 and the base plate 21 are locked together by fasteners (not shown), and the seal 24 is clamped between the cover plate 22 and the base plate 21 in a way that allows for elastic deformation. The position of the seal 24 can be planar (see [reference]). Figure 4 and Figure 5 As shown, the edges of the inner surfaces of the base plate 21 and the cover plate 22 are relatively flat, and they may also be provided with sealing grooves 210 and / or sealing protrusions 220, such as... Figure 8 As shown, taking the example of a sealing protrusion 220 on the cover plate 22 and a sealing groove 210 on the base plate 21, the sealing element 24 is located within the sealing groove 210 and is pressed tightly by the sealing protrusion 220. Of course, in Figure 8 In the illustrated embodiment, the sealing element 24 is simultaneously disposed on the partition rib 23, and correspondingly, the sealing protrusion 220 and / or the sealing groove 210 can be simultaneously disposed on the partition rib 23. In more embodiments, at least a portion of the sealing protrusion 220 and the sealing groove 210 can be interchanged, as long as the sealing element 24 can be limited and pressed.

[0098] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
