Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, and in particular to a dishwasher with a multi-layer heat insulation and noise reduction structure. Background Technology

[0002] A dishwasher is a device that automatically cleans tableware such as bowls, chopsticks, plates, dishes, knives, and forks. Based on installation method, they can be divided into built-in, freestanding, countertop, and sink-type dishwashers. Dishwashers produce some noise during the washing process, which can affect the user experience.

[0003] Most sink dishwashers on the market today use ordinary asphalt damping sheets on the sink, primarily for vibration reduction and noise reduction. However, a single layer of asphalt damping sheet has limited heat insulation and noise reduction effects, making it difficult to meet the needs of users with high noise reduction requirements. Therefore, this paper proposes an improved dishwasher with a multi-layered heat insulation and noise reduction structure. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a dishwasher with a multi-layer heat insulation and noise reduction structure to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a dishwasher with a multi-layer heat insulation and noise reduction structure, including a dishwasher body, a washing basin on one side of the dishwasher body, a washing assembly at the bottom of the washing basin, a heat insulation layer on the outer side of the washing basin, and a noise reduction box on the outer side of the heat insulation layer; an inner wall is fixedly connected to the inner side of the noise reduction box, a first partition and a second partition are provided between the inner wall and the noise reduction box, a plurality of sound guide tubes are fixedly connected inside the noise reduction box, penetrating the first partition, the second partition and the inner wall, a sound receiving tube is fixedly connected to the inner end of the sound guide tube and attached to the heat insulation layer, a horizontal tube is fixedly connected to the outer end of the sound guide tube, a honeycomb segment is provided between the first partition and the second partition, and a plurality of vertical partitions are provided inside the noise reduction box.

[0007] Preferably, in any of the above embodiments, the bottom surface of both the heat insulation layer and the noise reduction box is fixedly connected to the outside of the dishwashing assembly.

[0008] The above technical solution involves a dishwasher body that provides an installation platform for a sink and other structures. The sink holds the dishes and utensils to be washed, while the washing assembly cleans them. An insulation layer is installed on the outside of the sink to insulate against internal and external heat, retaining heat within the sink, improving washing efficiency, and saving energy. A noise reduction chamber isolates sound from the sink, reducing the environmental impact of noise during washing. The insulation layer and the bottom of the noise reduction chamber are fixed to the washing assembly, ensuring that the exposed bottom of the sink is also protected from heat and noise.

[0009] Preferably, the insulation layer is a bubble wrap or pearl cotton, as described in any of the above solutions.

[0010] The above technical solution employs an insulation layer to prevent heat transfer between the inside and outside of the sink. This layer uses bubble wrap, which is made from high-pressure polyethylene bubble film that has been cut to the required bag dimensions using a specialized bubble wrap bag-making machine. The bubble film is made from high-pressure low-density polyethylene. The air inside the bubble wrap provides excellent insulation, effectively blocking heat radiation from the sink's perimeter.

[0011] Pearl cotton is a type of polyethylene foam with a non-crosslinked closed-cell structure. It is composed of countless independent air bubbles generated by the physical foaming of low-density polyethylene resin. This overcomes the shortcomings of ordinary foam, such as fragility, deformation, and poor resilience. It possesses numerous advantages, including water and moisture resistance, shock absorption, sound insulation, heat insulation, excellent plasticity, high toughness, recyclability, environmental friendliness, and strong impact resistance. It can also effectively isolate heat radiation from the sink.

[0012] Preferably, as described in any of the above embodiments, a damping plate is provided on the outer surface of the heat insulation layer, and the damping plate on the outer surface of the heat insulation layer is an aluminum foil asphalt damping plate.

[0013] The above technical solution involves installing a damping plate on the outside of the insulation layer to block heat radiation. The damping plate is made of aluminum foil asphalt, with aluminum foil on top to reflect some of the heat radiation, achieving a dual insulation effect. Simultaneously, both the insulation layer and the damping plate can absorb some vibration effects, reducing source noise.

[0014] Preferably, in any of the above schemes, the height of the first partition and the second partition is the same as the height of the noise reduction box, and several of the sound guide tubes are evenly arranged along the width and height directions of the noise reduction box.

[0015] The above technical solution involves installing a first partition and a second partition inside the noise-reducing chamber. These partitions divide the internal space of the chamber into several individual spaces, effectively blocking and reflecting sound waves. Sound guide tubes are used to guide the sound waves generated in the sink, allowing them to travel into the noise-reducing chamber. Several sound guide tubes are evenly distributed to facilitate the propagation of sound from various locations within the sink into the noise-reducing chamber.

[0016] Preferably, in any of the above schemes, the receiver is made of a flexible material, and several of the vertical partitions are symmetrically arranged on both sides of the sound guide tube.

[0017] The above technical solution employs a sound-collecting hopper to guide sound waves emanating from the sink, concentrating them at the sound-collecting tube. Made of flexible material, it deforms slightly with the sink's vibrations, preventing motion interference. After entering the noise-reducing chamber through the sound-collecting tube and horizontal tube, the sound waves repeatedly reflect between the vertical partitions, thus reducing the noise's impact on the external environment. The honeycomb segments on the sound-collecting tube also allow sound waves to propagate outwards; similarly, these sound waves are repeatedly reflected and transmitted between the vertical partitions, the first partition, and the second partition, further reducing the noise's impact on the external environment.

[0018] Preferably, in any of the above schemes, the first partition is provided with a plurality of secondary conduits, which are symmetrically arranged on the outside of the sound guide tube and are located between the vertical partition and the sound guide tube.

[0019] The above technical solution involves installing a secondary conduit on the first partition, allowing sound waves to pass through. This causes the sound waves to repeatedly reflect between the second partition and the inner wall, thus interfering with and weakening the sound waves that are repeatedly reflected between the vertical partitions. The vertical partitions, the first partition, the second partition, the noise reduction box, and the inner wall together form a structure similar to a shielding box, effectively blocking the sound waves.

[0020] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0021] 1. This multi-layered heat insulation and noise reduction dishwasher utilizes a structure including an insulation layer, a noise reduction chamber, an inner wall, a first partition, a second partition, a sound guide tube, a sound receiving hopper, and horizontal pipes. The sound receiving hopper guides sound waves emanating from the sink, concentrating them at the sound guide tube. After entering the noise reduction chamber through the sound guide tube and horizontal pipe, the sound waves repeatedly reflect between the vertical partitions, thus reducing the impact of noise on the external environment. The honeycomb segments on the sound guide tube also allow sound waves to propagate outwards; similarly, these sound waves are repeatedly reflected and transmitted between the vertical partitions, the first partition, and the second partition, further reducing the noise impact on the external environment. The vertical partitions, the first partition, the second partition, the noise reduction chamber, and the inner wall form a shield-like structure that blocks sound waves, resulting in superior noise reduction.

[0022] 2. This dishwasher features a multi-layered heat insulation and noise reduction structure with several evenly distributed sound guide tubes, facilitating the transmission of sound from various parts of the sink into the noise reduction chamber. The sound-collecting bucket is made of flexible material, allowing it to deform slightly with the vibration of the sink, thus preventing motion interference. A secondary guide tube is installed on the first partition, allowing sound waves to pass through and causing them to repeatedly reflect between the second partition and the inner wall. This effectively interferes with and weakens the sound waves that repeatedly reflect between the vertical partitions.

[0023] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] like Figures 1-4 As shown, this utility model includes a dishwasher body 1, a sink 2 on one side of the dishwasher body 1, a washing assembly 3 at the bottom of the sink 2, a heat insulation layer 4 on the outside of the sink 2, and a noise reduction box 5 on the outside of the heat insulation layer 4. An inner wall 6 is fixedly connected to the inner side of the noise reduction box 5, and a first partition 7 and a second partition 8 are provided between the inner wall 6 and the noise reduction box 5. Several sound guide tubes 10 are fixedly connected inside the noise reduction box 5, passing through the first partition 7, the second partition 8 and the inner wall 6. A sound receiving tube 9 attached to the heat insulation layer 4 is fixedly connected to the inner end of the sound guide tube 10, and a horizontal tube 11 is fixedly connected to the outer end of the sound guide tube 10. A honeycomb segment 12 is provided between the first partition 7 and the second partition 8 of the sound guide tube 10. Several vertical partitions 13 are provided inside the noise reduction box 5.

[0033] Example 1: The bottom surfaces of the heat insulation layer 4 and the noise reduction box 5 are both fixedly connected to the outside of the dishwasher assembly 3. The dishwasher body 1 provides an installation platform for structures such as the sink 2, which is used to hold dishes and utensils to be washed, while the dishwasher assembly 3 is used to wash the dishes and utensils. A heat insulation layer 4 is provided on the outside of the sink 2 to isolate internal and external heat, retaining the heat inside the sink 2, improving washing efficiency, and saving energy. The noise reduction box 5 is used to isolate sound inside the sink 2, reducing the impact of noise on the environment during dishwashing. The bottom surfaces of the heat insulation layer 4 and the noise reduction box 5 are fixed to the dishwasher assembly 3, so that the exposed bottom part of the sink 2 also receives heat insulation and noise reduction protection.

[0034] The insulation layer 4 is made of bubble wrap or pearl cotton. Insulation layer 4 is used to isolate heat transfer between the inside and outside of the sink 2. It uses bubble wrap, which is made from high-pressure polyethylene bubble film that has been cut to the required bag size and then processed using a specialized bubble film bag-making machine. The bubble film is made of high-pressure low-density polyethylene. The air inside the bubble wrap has excellent heat insulation properties, effectively isolating heat radiation from the sink 2. Pearl cotton is polyethylene foam with a non-crosslinked closed-cell structure. It is composed of countless independent air bubbles generated by the physical foaming of low-density polyethylene resin. This overcomes the shortcomings of ordinary foam, such as fragility, deformation, and poor resilience. It has many advantages, including water and moisture resistance, shock absorption, sound insulation, heat insulation, good plasticity, high toughness, recyclability, environmental friendliness, and strong impact resistance. It can also effectively isolate heat radiation from the sink 2.

[0035] Example 2: A damping plate is provided on the outer surface of the heat insulation layer 4. The damping plate on the outer surface of the heat insulation layer 4 is an aluminum foil asphalt damping plate. The damping plate is provided on the outside of the heat insulation layer 4 to block heat radiation. The damping plate is made of aluminum foil asphalt damping plate, with aluminum foil on it, which can reflect part of the heat radiation, achieving a double heat insulation effect. At the same time, both the heat insulation layer 4 and the damping plate can absorb part of the vibration effect and reduce the source noise. The height of the first partition 7 and the second partition 8 is the same as the height of the noise reduction box 5. Several sound guide tubes 10 are evenly arranged along the width and height of the noise reduction box 5. The first partition 7 and the second partition 8 are provided inside the noise reduction box 5. The partitions divide the internal space of the noise reduction box 5 into several individual spaces, which can block and reflect sound waves. The sound guide tubes 10 are used to guide the sound waves generated in the sink 2, so that the sound waves are conducted into the noise reduction box 5. Several sound guide tubes 10 are evenly arranged to facilitate the propagation of sound from all places in the sink 2 into the noise reduction box 5.

[0036] Example 3: The sound-receiving hopper 9 is made of flexible material, and several vertical partitions 13 are symmetrically arranged on both sides of the sound-guiding tube 10. The sound-receiving hopper 9 is used to guide the sound emanating from the sink 2, allowing the sound waves to converge at the sound-guiding tube 10. Its flexible material allows it to deform with the vibration of the sink 2, preventing motion interference. After the sound waves enter the noise reduction box 2 through the sound-guiding tube 10 and horizontal tube 11, they are repeatedly reflected between the vertical partitions 13, thus reducing the impact of noise on the external environment. The honeycomb segment 12 on the sound-guiding tube 10 can also transmit sound waves outwards. Similarly, this portion of the sound waves is repeatedly reflected and transmitted between the vertical partitions 13, the first partition 7, and the second partition 8, further reducing the impact of noise on the external environment. Several secondary conduits 14 are provided on the first partition 7, symmetrically arranged on the outside of the sound-guiding tube 10, and positioned between the vertical partitions 13 and the sound-guiding tube 10. A secondary conduit 14 is installed on the first partition 7, allowing sound waves to pass through. This causes the sound waves to be repeatedly reflected between the second partition 8 and the inner wall 6, thus interfering with the sound waves that are repeatedly reflected between the vertical partitions 13 and weakening them. The vertical partitions 13, the first partition 7, the second partition 8, the noise reduction box 5, and the inner wall 6 form a structure similar to a shielding box, which blocks the sound waves.

[0037] The working principle of this utility model is as follows:

[0038] S1. When the dishwasher is working, the heat insulation layer 4 isolates the heat inside and outside, so that the heat in the sink 2 is retained, improving cleaning efficiency and saving energy.

[0039] S2 and the sound-collecting hopper 9 guide the sound waves emanating from the sink 2, allowing them to converge at the sound-collecting tube 10. After the sound waves pass through the sound-collecting tube 10 and the horizontal tube 11 into the noise reduction box 2, they are repeatedly reflected between the vertical partitions 13, thus reducing the impact of noise on the external environment.

[0040] S3. The honeycomb segment 12 on the sound guide tube 10 can also transmit sound waves outward. Similarly, this part of the sound waves is repeatedly reflected and transmitted between the vertical partition 13, the first partition 7, and the second partition 8, which can further reduce the impact of noise on the external environment.

[0041] Compared with the prior art, the present invention has the following advantages:

[0042] 1. This multi-layered heat insulation and noise reduction dishwasher, through the arrangement of a heat insulation layer 4, a noise reduction box 5, an inner wall 6, a first partition 7, a second partition 8, a sound guide tube 10, a sound receiving hopper 9, and a horizontal pipe 11, etc., guides the sound emanating from the sink 2, allowing the sound waves to converge at the sound guide tube 10. After the sound waves enter the noise reduction box 2 through the sound guide tube 10 and the horizontal pipe 11, they are repeatedly reflected between the vertical partitions 13, thus reducing the impact of noise on the external environment. The honeycomb segments 12 on the sound guide tube 10 can also transmit sound waves outward. Similarly, this part of the sound waves is repeatedly reflected and transmitted between the vertical partitions 13, the first partition 7, and the second partition 8, further reducing the impact of noise on the external environment. The vertical partitions 13, the first partition 7, the second partition 8, the noise reduction box 5, and the inner wall 6 form a shield-like structure that blocks sound waves, resulting in a more excellent noise reduction effect.

[0043] 2. This dishwasher with a multi-layered heat insulation and noise reduction structure has several evenly arranged sound guide tubes 10, facilitating the transmission of sound from various parts of the sink 2 into the noise reduction box 5. The sound receiving bucket 9 is made of flexible material, which can deform to a certain extent with the vibration of the sink 2, avoiding motion interference. A secondary conduit 14 is set on the first partition 7, allowing sound waves to pass through and causing the sound waves to be repeatedly reflected between the second partition 8 and the inner wall 6. This can interfere with the sound waves repeatedly reflected between the vertical partitions 13, thus weakening the sound waves.
