Description

Technical Field

[0001] The utility model relates to the technical field of water purifying and drinking machines, and more specifically, to an embedded water purifying and drinking machine. Background Art

[0002] The water purifying and drinking machine integrates water purification and drinking. According to different household use area scenarios, it has developed into various structural installation forms such as under-counter type, countertop type, wall-mounted type, etc. For example, the embedded water purifying and drinking machine is more and more favored by consumers because it can be completely embedded in the cabinet or wall and form a coordinated whole with the overall kitchen. The raw water from the outside is directly introduced into the water purifying and drinking machine, and the purified water obtained by filtration flows into the user's liquid-containing cup from the water outlet of the water purifying and drinking machine.

[0003] The installation of the embedded water purifying and drinking machine has certain particularity. Compared with the conventional countertop type, the whole machine of the embedded water purifying and drinking machine is completely embedded and hidden in the cabinet or wall, the installation space is very limited, and there will be no large gaps reserved between the water purifying and drinking machine and the surrounding cabinet or wall. This also results in a relatively close fit between the embedded water purifying and drinking machine and the surrounding cabinet or wall. During the use of the water purifying and drinking machine, the problems of vibration and noise have always been the focus of attention in the industry. Especially for the embedded water purifying and drinking machine, which is integrally embedded inside the wall or cabinet, the vibration and noise of the machine body are also easy to be transmitted to the cabinet or wall, and the resonance transmission is more likely to amplify the problems of vibration and noise. Moreover, once the embedded water purifying and drinking machine is installed, it is not convenient for users to move it frequently, and the problems of vibration and noise are also difficult to effectively overcome. How to reduce vibration and noise has also become an important factor affecting the user experience. Summary of the Utility Model

[0004] 1. Technical problems to be solved by the utility model

[0005] Aiming at the situation in the prior art that the installation space of the embedded water purifying and drinking machine is narrow, it is relatively close to the surrounding walls and cabinets, and the problems of vibration and noise of the machine body are more likely to be amplified, affecting the user experience. The utility model intends to provide an embedded water purifying and drinking machine, which helps to alleviate the problems of vibration and noise of the water purifying and drinking machine through the optimization of the internal structure of the machine body, also reduces the damage to the wall or cabinet, and has a simple structure, is easy to implement, and is suitable for popularization and application.

[0006] 2. Technical solutions

[0007] To achieve the above object, the technical solutions provided by the utility model are as follows:

[0008] An embedded water purifier of the present utility model includes a front panel, a water circuit board, and an installation middle frame. The front panel is the front appearance panel of the embedded water purifier, and there is a water receiving area facing the user at the front panel. In practice, the rear side wall and the surrounding wall surfaces of the water purifier are all embedded in a wall or a cabinet, and do not extend beyond the four peripheral edges of the front panel in the up, down, left, and right directions. Thus, only the front panel can be observed after installation, and it can form a relatively beautiful unified whole with the wall or the cabinet; the water circuit board is located inside the water purifier and is used for water circuit distribution; the installation middle frame is located inside the water purifier and is used for installing internal components, such as functional components like a filter element module, a water tank, a refrigeration module, a heating module, etc.; particularly, in this solution, the water circuit board is longitudinally arranged inside the water purifier and is close to a certain side edge position of the water purifier. The front wall surface of the water circuit board is an installation surface for installing the filter element module, and there is an installation middle frame in front of the installation surface of the water circuit board. The installation middle frame is provided with a laterally extending filter element installation cylinder, and the filter element installation cylinder is used for the filter element module to be inserted and connected to the installation surface of the water circuit board; at least part of the back side surface of the water circuit board facing away from the installation middle frame is covered with a water circuit isolation layer; or / and, at least part of the outer peripheral wall surface of the filter element installation cylinder is covered with a filter cylinder isolation layer.

[0009] In a water purifier, the water circuit board is used for water circuit distribution. It has complex and variable flow channels inside for water flow at any time. Generally, the width and length of the flow channels on the water circuit board are limited by the volume, and the space is relatively limited. Water flow turning and impact are likely to cause vibration and noise problems. The filter element installation cylinder is used to install the filter element, and water flow is also constantly occurring inside the filter element. Both of them belong to the areas where water flow impact is more widely distributed inside the water purifier. In addition, multiple sets of power pump structures including a booster pump generally need to be set on the water circuit board. Especially when the booster pump operates, obvious vibration and noise are further generated. There will also be obvious vibration and noise when the filter element module operates. It not only conducts resonance transmission inside the machine body, but also generates resonance between the wall and the cabinet body, further amplifying the vibration and noise problems. In this solution, an isolation layer is wrapped on the back side of the water circuit board and the outer peripheral wall surface of the filter element installation cylinder. Specifically, the water circuit isolation layer and the filter cylinder isolation layer can be made of heat-insulating cotton or foam material, and can be fixed by bonding. At a certain edge position of the water circuit board close to the water purifier, that is, at a certain edge wall surface close to the water purifier. In practice, for an embedded water purifier, except for the front panel facing the user, the remaining four wall surfaces are hidden inside. It can be chosen not to set other appearance panels or to set other appearance panels. When no other appearance panels are set, the back side of the water circuit board close to a certain edge wall surface of the water purifier can be understood as the back side of the water circuit board close to the wall or the inner wall of the cabinet where it is installed. The isolation layer can effectively isolate between the back side of the water circuit board and the wall or the cabinet, avoiding the resonance transmission of the vibration inside the water circuit board and the machine body to the wall or the cabinet, thereby avoiding further amplification of vibration and noise, and also avoiding damage caused by direct contact between the wall or the cabinet and the water circuit board. Similarly, wrapping an isolation layer around the outer periphery of the filter element installation cylinder can also effectively alleviate the resonance transmission problem.

[0010] To adapt to the compact layout of the embedded water purifier, in this solution, the water circuit board is longitudinally arranged and close to one edge. Preferably, the water circuit board is set at the rear position inside the water purifier, and its thickness direction extends along the front-back direction of the water purifier. The front wall surface of the water circuit board is the installation surface, and the installation middle frame is located between the installation surface of the water circuit board and the front panel. In this way, the water circuit board leans against the rear side of the water purifier, and its back side is close to the rear side of the wall or the cabinet. The setting of the isolation layer further forms a protection between the water circuit board and the wall or the cabinet, not only further reducing vibration and noise, but also avoiding damage caused by direct contact between the wall or the cabinet and the water circuit board.

[0011] Similarly, in this solution, it is preferred that the filter element installation cylinder is located at a position on the installation middle frame close to the left or right edge side wall of the water purifier, that is, the filter element installation cylinder is also close to the edge position of the water purifier, that is, close to the side wall of the wall or the cabinet. The setting of the isolation layer forms a protection between the filter element installation cylinder and the wall or the cabinet, not only further reducing vibration and noise, but also avoiding damage caused by direct contact.

[0012] To fully ensure the effectiveness of the isolation layer, preferably, no installation interface is provided on the back side of the water channel plate, so as to facilitate full coverage on the back side, make the coverage area of the water channel isolation layer not less than the area of the back side of the water channel plate, and achieve full protection and sufficient vibration reduction of the back side of the water channel plate. Similarly, the filter cartridge isolation layer is at least wrapped on the outer side wall surface of the filter element installation cylinder in the direction close to the left / right edge side wall of the water purifier, so as to have isolation protection and vibration reduction and noise reduction at least at the position close to the wall cabinet. Preferably, the filter cartridge isolation layer can also be comprehensively wrapped around the circumferential side wall of the filter element installation cylinder to fully isolate, protect, reduce vibration and noise.

[0013] Preferably, in this solution, a back plate is provided at the rear side of the water purifier as an appearance panel, the water channel plate is arranged inside the back plate and is as close to and attached to the back plate as possible, and the water channel isolation layer is located between the water channel plate and the back plate. Similarly, a left side plate and a right side plate are respectively provided on the left and right sides of the water purifier as appearance panels, the installation middle frame is located between the left side plate and the right side plate, and the filter element installation cylinder is located on one side of the installation middle frame close to the left side plate or the right side plate, that is, the filter element installation cylinder is located on one side in the left-right direction of the installation middle frame.

[0014] In this solution, preferably, two filter element installation cylinders are provided corresponding up and down and parallel in the height direction of the upper edge of the installation middle frame, the rear ends of the two filter element installation cylinders are respectively connected to the water channel plate correspondingly, and the two filter element modules are independently arranged, which is convenient for individual replacement and also convenient for selecting and using water of different filtration grades. Correspondingly, the filter cartridge isolation layer is wrapped on the outer circumferential wall surfaces of the two filter element installation cylinders close to the left side plate or the right side plate.

[0015] In practice, optionally, a water purification tank is provided in the water purifier, the water purification tank is used to store the filtered purified water, and the outer periphery of the water purification tank is wrapped with a water purification isolation layer; or / and, a refrigeration module and a cold water tank are provided in the water purifier, the cold water tank is connected to the refrigeration module and is used to store cold water, and the outer periphery of the cold water tank is wrapped with a cold water isolation layer. The water purification isolation layer and the cold water isolation layer can also be made of heat-insulating cotton or foam material and wrapped by an adhesive method, which also helps in isolation and protection and can effectively keep warm. Especially for the cold water tank, a single-layer or multi-layer isolation layer can be set to fully keep warm and ensure the cold water temperature. Description of the Drawings

[0030] The following further describes the present utility model in conjunction with embodiments

[0031] Embodiment

[0032] Combined with Figures 1 - 5As shown in the figure, an embedded water purifier of this embodiment includes a front panel 120, a water circuit board 200, an installation middle frame 300, etc. The front panel 120 is the front appearance panel of the embedded water purifier, and there is a water receiving area facing the user at the front panel 120. The rear side wall surface and the surrounding wall surfaces of the water purifier are all embedded in the accommodation space of the water purifier, and do not extend beyond the four peripheral edges of the front panel 120 in the up, down, left, and right directions; the water circuit board 200 is located inside the water purifier; the installation middle frame 300 is located inside the water purifier and is used for installing internal components such as a filter element module, a refrigeration module, a heating module, etc.; in this embodiment, the water circuit board 200 is longitudinally arranged inside the water purifier and is close to a certain side edge position of the water purifier. The front wall surface of the water circuit board 200 is an installation surface for installing the filter element module, and there is an installation middle frame 300 in front of the installation surface of the water circuit board 200. There is a horizontally extending filter element installation cylinder 301 on the installation middle frame 300, and the filter element installation cylinder 301 is used for the filter element module to be inserted and connected to the installation surface of the water circuit board 200; at least part of the back side surface of the water circuit board 200 facing away from the installation middle frame 300 is covered with a water circuit isolation layer 202; and / or, at least part of the outer peripheral wall surface of the filter element installation cylinder 301 is covered with a filter cylinder isolation layer 302. The filter cylinder isolation layer 302 and the water circuit isolation layer 202 can be set separately or simultaneously.

[0033] In practice, the water circuit isolation layer 202 and the filter cylinder isolation layer 302 can preferably adopt thermal insulation cotton or foam materials, and are preferably covered and fixed by an adhesive method. Using the isolation layer covering has excellent vibration reduction and noise reduction effects. Especially for the water circuit board 200 and the filter element installation cylinder 301, the water circuit board 200 has complex and diverse water circuit pipelines, water valve groups, pump groups and other structures, and a filter element module for filtering water at any time is installed in the filter element installation cylinder 301. Relatively speaking, the water flow distribution range and water flow impact faced by both are more obvious, and the water circuit board 200 and the filter element installation cylinder 301 are connected in cooperation. After the filter element module is inserted into the filter element installation cylinder 301, it is connected in cooperation with the corresponding filter element seat on the water circuit board 200. The vibration transmission between the two is inevitable, and the need for vibration reduction and noise reduction is more urgent. In this embodiment, for the water circuit board 200 and the filter element installation cylinder 301, a special isolation layer is set for adhesive covering to avoid resonance transmission. Especially, the water circuit board 200 and the filter element installation cylinder 301 can be installed at a position close to the edge of the water purifier, that is, close to the cabinet or wall, and can also effectively isolate between the cabinet or wall, avoiding contact collision and further avoiding resonance transmission, reducing vibration and noise.

[0034] It should also be noted that when external raw water enters the inside of the water purifier in practice, there are still problems that cannot be ignored. Condensate is likely to form inside the water dispenser, especially in the water circuit board area and the filter element area. As the areas where water flow is most concentrated, it is easier for surface water vapor to condense due to temperature differences. The accumulation and flow of condensate inside the machine can easily pose a safety hazard, and the overflow of condensate will create an illusion of water leakage in the water dispenser. Especially for built-in water dispensers, the overflowed condensate is not easily detected in time, and it is likely to erode the cabinet or wall over a long period, even leading to mildew. In conventional home designs, multiple built-in spaces are often provided on the wall or in the cabinet to place multiple built-in household appliances in layers. For example, a water dispenser is placed on the upper layer and a microwave oven is placed on the lower layer. If the water dispenser leaks, the water flowing down to the lower electrical appliance can easily damage other electrical appliances, causing greater losses. In the prior art, to prevent condensate, methods such as enhancing heat dissipation or additional collection are generally adopted. For example, the patent with publication number CN208822393U provides a built-in water dispenser. This design has a condenser heat dissipation port and a condenser heat dissipation component on the back panel of the machine shell, and quickly removes the heat accumulated in the air around the condenser by enhancing heat dissipation, thereby alleviating the formation of condensate. However, the practical effect is difficult to meet the requirements. The patent with publication number CN111592056A provides an anti-condensate device inside a water purifier. On the one hand, by setting heat sinks, the protected devices inside the water purifier can be heated to prevent the formation of condensate; on the other hand, the condensate is collected and centrally processed through a water collection container to prevent the condensate from evaporating again or flowing around. However, this structural design is relatively complex, and the additional setting of a water collection container will inevitably increase the volume of the machine body. Since the installation space of a built-in water dispenser is already limited, it is even more difficult to apply.

[0035] In this solution, an insulating layer is wrapped around the back side of the water circuit board 200 and the outer periphery of the filter element installation cylinder 301. While reducing vibration and noise, the water circuit board 200 and the filter element installation cylinder 301 can be effectively isolated from the air respectively, thereby avoiding the condensation and accumulation of air, reducing the generation of condensate, and avoiding potential safety hazards. It is not only convenient to operate and has a simple structure, but also achieves multiple benefits at one stroke, with a low implementation cost and is extremely easy to promote and apply.

[0036] As an optimized layout of the built-in water purifier, in this embodiment, it is preferably to arrange the water circuit board 200 at the rear position inside the water purifier. Its thickness direction extends along the front-rear direction of the water purifier, its length direction extends along the left-right length direction of the water purifier, and its width direction extends along the up-down height direction of the water purifier. The bottom of the water circuit board 200 has at least one connection water port 201. The connection water port 201 is located at the bottom of the thickness wall surface of the water circuit board 200 and extends downward for connecting with an external pipeline. In this way, the front wall surface of the water circuit board 200 is the installation surface, and the installation middle frame 300 is located between the installation surface of the water circuit board 200 and the front panel 120; the water circuit board 200 is arranged at the rearmost position of the water purifier, and further preferably, no installation interface is provided on the back side surface of the water circuit board 200, so as to facilitate the full bonding of the water isolation layer 202 on the back side surface, so that the coverage area of the water isolation layer 202 is not less than the area of the back side surface of the water circuit board 200. At this time, the water isolation layer 202 can not only play a better anti-condensation effect, but also isolate and protect between the water circuit board 200 and the rear edge of the water purifier, and has the effects of anti-contact, anti-impact, and anti-resonance transmission, etc.

[0037] Similarly, in this embodiment, it is preferably to arrange the filter element installation cylinder 301 at a position on the side wall of the installation middle frame 300 close to the left or right edge of the water purifier, and preferably, the filter cylinder isolation layer 302 at least wraps around the outer side wall surface of the filter element installation cylinder 301 in the direction of the left or right edge of the water purifier. For example, Figure 2 as an example, in this embodiment, the filter element installation cylinder 301 is located at the left end in the left-right direction of the installation middle frame 300, close to the left edge wall surface of the water purifier. The filter element installation cylinder 301 is a cylindrical structure, and the filter cylinder isolation layer 302 is arranged at least on the semi-cylindrical wall surface on the left side. At this time, the filter cylinder isolation layer 302 can not only play a better anti-condensation effect, but also isolate and protect between the filter element installation cylinder 301 and the left edge of the water purifier, and has the effects of anti-contact, anti-impact, and anti-resonance transmission, etc.

[0038] As a built-in and hidden installation method, in addition to the front panel 120 facing the user, the other wall surfaces of the built-in water purifier can be hidden inside the wall or cabinet. Therefore, an appearance panel can be selectively set or not set. In this embodiment, it is preferably that a back panel 100 is provided at the rear side of the water purifier as the appearance panel. The water circuit board 200 is arranged inside the back panel 100 and close to the back panel 100, and the water isolation layer 202 is located between the water circuit board 200 and the back panel 100. On the left and right sides of the water purifier, a left side panel 130 and a right side panel 140 are preferably provided as the appearance panels respectively. The installation middle frame 300 is located between the left side panel 130 and the right side panel 140, and the filter element installation cylinder 301 is located on one side of the installation middle frame 300 close to the left side panel 130 or the right side panel 140. For example, Figure 2It is located on one side close to the left side plate 130. At this time, the waterway isolation layer 202 isolates between the waterway plate 200 and the back plate 100, and the filter cartridge isolation layer 302 isolates between the filter cartridge installation cylinder 301 and the left side plate 130, further preventing vibration from being transmitted to the appearance panel and the cabinet wall of the water purifier and ensuring the vibration reduction and noise reduction effect.

[0039] In practice, at least one filter cartridge module can be provided in the water purifier. For example, in this embodiment, two filter cartridge modules are provided. Two filter cartridge installation cylinders 301 are provided on the installation middle frame 300 corresponding to each other and parallel in the height direction. Filter cartridge isolation layers 302 are coated on the outer circumferential wall surfaces of the two filter cartridge installation cylinders 301 close to the left side plate 130 or the right side plate 140. The two filter cartridge installation cylinders 301 are compactly arranged up and down, and at the same time help to streamline the volume of the waterway plate 200.

[0040] In practice, other components are also included in the water purifier. For example, a water purification tank 400 can be additionally provided to store the filtered purified water. As shown in Figure 3 shown, the water purification tank 400 can be arranged at the upper part of the installation middle frame 300 and above the filter cartridge installation cylinder 301. A purified water isolation layer 401 is coated on the outer periphery of the water purification tank 400. For example, a refrigeration module 600 and a cold water tank 500 can be provided in the water purifier. The cold water tank 500 is connected to the refrigeration module 600 and used to store cold water. As shown in Figure 3 shown, the refrigeration module 600 is arranged at the bottom on the right side of the water purifier, the cold water tank 500 is located above the refrigeration module 600, and a cold water isolation layer 501 is coated on the outer periphery of the cold water tank 500. The purified water isolation layer 401 and the cold water isolation layer 501 can also be made of heat-insulating cotton or foam materials, and the two can exist alone or simultaneously. Similarly, the setting of the isolation layer here not only helps to prevent condensation and reduce vibration and noise, but also has a good heat preservation effect. Especially for the cold water tank 500, at least one layer of isolation layer can be provided to ensure the cold water temperature.

[0041] The above schematically describes the present invention and its implementation manners. This description is not restrictive. It is only one of the implementation manners of the present invention, and the actual situation is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and without departing from the creative purpose of the present invention, without creative design, they create structural manners and embodiments similar to this technical solution, which should all fall within the protection scope of the present invention.
