Description

Technical Field

[0001] This utility model relates to the field of water dispenser heat dissipation technology, and more specifically, to a ventilation and heat dissipation structure for a water dispenser. Background Technology

[0002] As a core drinking water device in modern homes, offices, and public places, water dispensers can provide instant hot water, room temperature water, and cold water to meet diverse needs and offer high convenience. In addition, water dispensers are generally used in conjunction with filtration systems to ensure water quality safety and better meet users' requirements for healthy drinking water.

[0003] With the upgrading of consumption, the market share of water dispensers with cooling functions is increasing year by year. However, the introduction of the cooling module has also brought about the problem of internal heat accumulation. The ineffective dissipation of internal heat can not only easily affect internal components, leading to an increased failure rate or even a shortened lifespan, but also reduce cooling efficiency due to high internal temperature, resulting in the water temperature failing to meet the standard and affecting the user experience. Therefore, it is urgent to optimize the heat dissipation structure of water dispensers to ensure the reliability of the equipment.

[0004] Currently, the heat dissipation design of water dispensers varies widely in the industry. For example, patent CN220988481U discloses a water purifier with an air inlet on the side wall of the casing and an air outlet on the front panel, using a fan to draw air from the side and exhaust it from the front. Patent CN222706843U discloses a heat dissipation structure for an embedded water purifier, with a ventilation area at the bottom and internal cooling fans and ducts, the ducts located at the front of the machine for exhaust cooling. Patent CN222968331U discloses a water purifier with a front-mounted forced exhaust cooling system, with air ducts at the bottom of the casing and air exhaust from the side. All of these designs address the issue of heat dissipation, but in practice, different machine structures will lead to differences in heat dissipation performance, and the heat dissipation structure needs to be adjusted according to the arrangement of internal functional components. Utility Model Content

[0005] 1. Technical problem to be solved by the utility model In view of the fact that the problem of internal heat accumulation is more obvious after the introduction of a refrigeration module in the existing water dispenser, and the requirements for the heat dissipation performance of the machine are higher, this utility model intends to provide a ventilation and heat dissipation structure for a water dispenser, which can set the heat dissipation path according to the internal structural layout of the machine, so as to fully ensure the heat dissipation effect and ensure the operational reliability of the machine.

[0006] 2.

[0007] Furthermore, the air intake channel includes: a concave area formed by the recess of the base sidewall facing the inside of the machine body, an air intake opening formed by the outer side of the concave area facing the outside, a ventilation plate provided at the top of the concave area, and an air intake hole provided on the ventilation plate, connecting the concave area with the air intake cavity at the bottom of the cooling module.

[0008] Furthermore, the bottom surface of the concave area is an inclined, extended guide surface, which facilitates the entry of external airflow into the concave area from the bottom.

[0009] Furthermore, the rear side of the cooling module facing the installation opening is provided with multiple sets of vertically extending heat dissipation fins.

[0010] Furthermore, the rear outer panel along the length of the casing is provided with an outwardly protruding post that extends beyond the wall surface where the heat dissipation channel is located.

[0011] Furthermore, the bottom of the air conditioning unit installation area also has a bottom support plate, on which the air conditioning unit module is supported, and the bottom support plate has a through opening that connects to the air inlet cavity at the bottom of the air conditioning unit module.

[0012] Furthermore, the bottom of the mounting frame is also equipped with support legs that extend below the bottom support plate and contact the base, forming an air intake cavity at the bottom of the cooling module between the support legs and the base.

[0013] Furthermore, a secondary air intake channel is located above the main air intake channel inside the unit. This secondary air intake channel connects outward to the outer side of the mounting frame and inward to the main air intake channel to draw air in from the inner side of the unit. The secondary air intake channel also connects to the air intake cavity at the bottom of the cooling module. Furthermore, a secondary air intake channel is formed by a height gap between the bottom outer side of the mounting frame and the top wall of the base.

[0014] Furthermore, it also includes an outer panel, and an outwardly extending outer edge plate is provided on the base above the recessed area. The bottom of the outer panel is supported on the outer edge plate, and there is an air intake gap between the secondary air intake channel and the outer panel.

[0015] 3. Beneficial effects Compared with the prior art, the technical solution provided by this utility model has the following advantages: (1) The heat dissipation structure of this utility model has an independent cold tank installation area that is separated from other areas. The cold tank module is installed at the rear end of the body in the length direction. The installation opening of the cold tank module faces the rear side of the body directly. A heat dissipation channel is provided on the outer panel to communicate with the outside. Air inlet channels are set on both sides of the bottom of the body to directly connect with the cold tank installation area, realizing the ventilation path of air inlet on both sides of the bottom and air outlet at the rear end.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Example Combination Figures 1-13 As shown, this embodiment provides a ventilation and heat dissipation structure for a water dispenser, including: The mounting frame 100 has a cooling liner mounting area 160 at the rear end along the length of the body. A mounting opening is formed at the rear side of the cooling liner mounting area 160. The cooling liner module 600 is installed into the cooling liner mounting area 160 along the mounting opening. A heat dissipation channel 105 is provided on the outer rear panel of the body corresponding to the mounting opening. An air intake cavity is formed between the bottom of the cooling liner module 600 and the bottom surface of the body. The base 110 is located at the bottom of the mounting frame 100. The base 110 has air inlet channels 180 on both sides corresponding to the bottom position of the cooling module 600. The air inlet channels 180 face the outside and are connected to the air inlet cavity at the bottom of the cooling module 600.

[0025] In this embodiment, an independent cooling liner mounting area 160 is provided at the rear end of the body along the length direction P, and an mounting opening is formed on the rear side. The cooling liner module 600 is installed into the body horizontally through the mounting opening. It cooperates with the heat dissipation channel 105 on the rear outer panel. A cooling fan 602 is also provided on the rear side of the cooling liner module 600 to form a direct air outlet path on the rear side. The bottom of the cooling liner module 600 has an air inlet cavity, and the air inlet channels 180 on both sides form a bottom side air inlet, so that the air inlet is at the bottom of the body and the air outlet is at the rear, which facilitates the rapid and sufficient heat dissipation of the cooling liner module 600.

[0026] Furthermore, in practice, a secondary air intake channel 115 is also provided inside the unit above the air intake channel 180. The secondary air intake channel 115 connects outward to the outer side of the mounting frame 100 and inward to the air intake channel 180 to allow air to enter from the side inside the unit. Both the air intake channel 180 and the secondary air intake channel 115 are connected to the air intake cavity at the bottom of the cooling liner module 600. Specifically, the secondary air intake channel 115 is formed by a height gap between the outer bottom of the mounting frame 100 and the top wall of the base 110, and the secondary air intake channel 115 connects inward to the air intake channel 180. In this way, the air intake channel 180, which is connected to the outside, serves as the main air intake structure, allowing air to enter from the bottom of the unit; the secondary air intake channel 115 utilizes the internal edge space of the unit to provide auxiliary air intake from the side, achieving multi-channel air intake and effectively improving ventilation and heat dissipation.

[0027] The following describes the overall structure of the water dispenser. In this embodiment, the water dispenser integrates heating and cooling functions and does not involve a built-in pure water tank. Through the reasonable layout of the internal structure, the size of the equipment can be effectively reduced, achieving miniaturization and compactness of the machine body, thus meeting the user's space requirements. Specifically, the water dispenser includes an internal mounting frame 100. Along the length of the machine body, the top of the mounting frame 100 sequentially forms a water spout mounting area 120 and an electrical control mounting area 130. The electrical control mounting area 130 houses the machine's electrical control module 300, and the water spout mounting area 120 houses a water spout module 200. A partition is provided between the water spout mounting area 120 and the electrical control mounting area 130 to achieve water and electricity separation between the electrical control module 300 and the water spout module 200. Below the electrical control mounting area 130, a cold tank mounting area 160 is formed, and a cold tank module 600 is installed within the cold tank mounting area 160. Below the water tap installation area 120, there are a water channel installation area 140 and an instant heating installation area 150. The water channel installation area 140 contains a water channel assembly 400, and the instant heating installation area 150 contains an instant heating module 500. The water channel installation area 140 and the instant heating installation area 150 are distributed sequentially along the width direction N of the machine body, that is, they are located on both sides of the width direction of the machine body.

[0028] In practice, the water circuit component 400 specifically includes multiple water circuit connecting pipes, as well as valve groups and pump groups installed on the water circuits, to realize the input of purified water to the instant heating module 500 and the cold tank module 600, and the output of room temperature water, hot water, and cold water to the faucet module 200. The valve groups and pump groups are used to control the opening and closing of each water circuit and to transmit power. The instant heating module 500 is used to heat the incoming purified water and send it to the faucet module 200, and the cold tank module 600 is used to cool the incoming purified water and send it to the faucet module 200. The electrical control module 300 is electrically connected to and controls the various electrical control components. This is standard technology in the industry and will not be described in detail here.

[0029] This embodiment integrates heating and cooling functions within the unit through the above design, without setting up an internal water tank. The largest cold tank module 600 is placed alone at one end of the length direction, and the water circuit components 400 are centrally distributed and positioned opposite the instant heating module 500 along the width direction. This makes the overall width of the unit consistent with the width of the cold tank module 600, and the length is also effectively simplified. The entire unit is extremely simple and thin, effectively achieving a compact layout, reducing the overall volume of the unit, and making it more adaptable to installation space.

[0030] Furthermore, corresponding to the thinner design of the machine body, auxiliary plates 111 can be provided on both sides of the bottom of the machine body along the width direction to strengthen the support width of the machine body, ensure the stability of the machine body and prevent tipping. Specifically, the bottom of the mounting frame 100 also has a base 110, and the auxiliary plates 111 are detachably set on the base 110, which can be selected by the user according to their needs.

[0031] In this embodiment, the water tap module 200 is located at the end of the body in the length direction P. Preferably, the water tap module 200 is rotatably engaged with the mounting frame 100, so that the water tap module 200 can rotate between two adjacent sides at the end of the mounting frame 100. The position of the water outlet of the water tap module 200 can be adjusted as needed, which is convenient for users to adapt to different installation space requirements. It has high space placement flexibility and also helps to save installation space.

[0032] In practice, condensation is more likely to occur in the area near the cooling unit module 600. In this embodiment, an independent cooling unit installation area 160 is formed within the mounting frame 100. Specifically, in conjunction with... Figure 7 As shown, along the width direction of the machine body, the mounting frame 100 has an outer side plate 173 and an outer side plate 175 on both sides. The outer side plate 173 and the outer side plate 175 extend along the length direction of the machine body, and a middle partition plate 171 connects one end of the length direction. The other end of the length direction forms an installation opening for the cooling module 600 to be installed horizontally. An upper partition plate 174 is provided on the upper part of the outer side plate 173 and the outer side plate 175. The electronic control module 300 is installed on the upper partition plate 174, which separates the cooling module 600 from the electronic control module 300. The upper partition plate 174, the middle partition plate 171, the outer side plate 173 and the outer side plate 175 together form a cooling installation area 160. Along the length direction of the machine body, the rear end of the cooling installation area 160 forms an installation opening, which facilitates the direct installation of the cooling module 600. At the same time, this installation opening area is used as a heat dissipation wall.

[0033] In practice, the rear side of the cooling module 600 is provided with vertically extending heat dissipation fins 601, which extend outwards towards the mounting opening. Correspondingly, a heat dissipation channel 105 is provided on the outer rear panel of the body along the length P to achieve effective heat dissipation. A cooling fan 602 is also provided between the heat dissipation fins 601 and the heat dissipation channel 105 on the outer panel of the body. In this embodiment, a dual air intake path (bottom and side) is adopted for the bottom area of ​​the cooling module 600. Combined with the vertical arrangement of the heat dissipation fins 601, airflow can directly enter from the bottom and then quickly flow upwards along the heat dissipation fins 601 and be discharged by the fan, resulting in better ventilation and heat dissipation.

[0034] In this embodiment, outer side panel 173 and outer side panel 175 are preferably attached to the two side panels along the width direction of the water dispenser body. No other functional components are installed on the outer sides of outer side panel 173 and outer side panel 175 along the width direction of the body to ensure a thinner design of the body and to allow the cold tank module 600 to be completely independent, preventing heat from diffusing to other internal components. Outer side panel 173 and outer side panel 175 are also provided with multiple through-holes 102 to facilitate the routing of pipes and wiring.

[0035] Specifically, the central partition 171 extends along the width of the fuselage, and further, combined with... Figure 5 and Figure 6 As shown, a second partition 172 is also provided on the side of the first partition 171 away from the cooling tank module 600. The second partition 172 extends along the length of the machine body and divides the first partition 171 along the width direction, thereby forming a water circuit installation area 140 and an instant heating installation area 150 on both sides of the second partition 172. The second partition 172 also effectively separates the water circuit assembly 400 and the instant heating module 500, realizing the separate installation of water and electrical components.

[0036] In this embodiment, an upper partition 174 separates the lower cooling tank module 600 from the top electrical control module 300, and a middle partition 171 effectively separates the cooling tank module 600 from the water circuit assembly 400 and the instant heating module 500. This allows for the independent layout and installation of the cooling tank module 600, reducing heat dissipation and preventing condensation from affecting other functional components. Furthermore, the separation of major functional components avoids mutual interference and achieves a compact layout. The water circuit installation area 140 and the instant heating installation area 150 are located below the faucet installation area 120 and are positioned opposite each other along their width. This effectively saves on the length of the connecting water pipes and allows the pipes to be concentrated within the water circuit installation area 140, further conserving space.

[0037] In this embodiment, the mounting frame 100 is also provided with a base 110 at the bottom. The base 110 is detachably installed from the mounting frame 100. The end of the base 110 away from the cold tank module 600 along the length direction is also provided with an inwardly recessed water collection area 114. The water collection area 114 is surrounded by inclined and extending guide walls. The area where the water collection area 114 is located corresponds to the end where the water circuit installation area 140 and the instant heating installation area 150 are located. The main water circuit pipes, pump groups, valve groups and other structures are all concentrated in the water circuit installation area 140. When a pipe leak occurs, the water flow can be concentrated in the water collection area 114 to avoid affecting other components. In addition, a water leakage protector is also provided at the bottom of the mounting frame 100 at the position corresponding to the water collection area 114. When the water leakage reaches a certain level, it can promptly alarm and remind.

[0038] In this embodiment, no pure water tank is installed inside the water dispenser, nor is a purification function integrated within the machine. In practical applications, the water dispenser can be used in conjunction with an independent external purification module or pure water tank module, depending on user needs. The purification module can be directly connected to the water dispenser to supply pure water, or the pure water tank can be used to supply pure water. The diagram does not show the configuration with a purification module or pure water tank. Correspondingly, in conjunction with... Figure 1 As shown, a water connector 103 is provided at the bottom of the water dispenser body for connecting to an external purification module or an external pure water tank. Furthermore, the water connector 103 is preferably located on the side of the water circuit installation area 140 for easy connection of water pipes. Outer side panels 173 on both sides of the body width direction are located on the side of the water circuit installation area 140, and outer side panels 175 are located on the side of the instant heating installation area 150. The water connector 103 is internally connected to the inlet end of the water circuit assembly 400 to supply pure water to the cold tank module 600 and the instant heating module 500.

[0039] Taking an externally mounted pure water tank as a water supply module as an example, the pure water tank is installed on the side of the water circuit installation area 140. A water tank base can be detachably installed on the side of the water dispenser body where the water connector 103 is located, and the pure water tank is placed on the water tank base and connected to the water connector 103 for water circuit connection. Specifically, the water tank base can be fixedly connected to the side of the water dispenser with bolts. The outer side plate 173 has threaded holes corresponding to the fixed connection position of the water tank base as mounting positions, and reinforcing ribs 101 are provided around the threaded hole area to enhance the structural strength of the outer side plate 173 in this connection area, ensuring the stability of the installation with the water tank base.

[0040] To facilitate the use of the water dispenser body with the external water supply module and the connection of pipelines, specifically, the base 110 has an upwardly protruding boss 113 corresponding to the location of the water connector 103, and an external interface area 112 recessed towards the inside of the machine body is formed below the boss 113. A cover plate can also be installed to conceal the outer opening of the external interface area 112. The water connector 103 extends from the external interface area 112 to connect to the external water supply module pipeline. Furthermore, in practice, it is preferable to also provide a circuit interface within the external interface area 112 for power connection to the water dispenser body and for circuit signal connection between the water dispenser body and the external purification module when used together. This achieves a hidden circuit interface. A wiring groove is provided at the bottom of the base 110, allowing wiring to be routed from the bottom of the base 110 after the circuit interface is connected, without affecting the aesthetics of the machine body, and making the machine body more compact.

[0041] Furthermore, the ventilation and heat dissipation structure in this embodiment is described in detail below. Air inlet channels 180 are provided on both sides of the width direction of the area where the cooling module 600 is located at the bottom of the unit. Combined with the end of the cooling module 600, this achieves a ventilation path where air enters from both sides of the bottom of the unit and exits from the rear. The air inlet channels 180 directly face the bottom of the cooling module 600 for close-range, rapid air intake, which helps enhance the heat dissipation effect. Combined with... Figure 9 and Figure 10 As shown, specifically, the air intake channel 180 is configured as follows: Both sides of the base 110 in the width direction have recessed areas 181 facing inwards towards the interior of the unit. A ventilation plate 182 is located at the top of the recessed area 181, and an air intake control is provided on the ventilation plate 182 to connect the recessed area to the bottom air intake cavity of the cooling module 600. Furthermore, the bottom surface of the recessed area 181 is an inclined, extending guide surface 185 to facilitate the entry of external airflow from the bottom. The recessed area 181 effectively ensures sufficient air intake space, especially when the installation space of the unit is relatively narrow, thus widening the air intake path width on both sides.

[0042] Furthermore, the mounting frame 100 has outer panels on all four sides of the unit body, and the outer panels on both sides along the width direction of the unit body protrude beyond the outer side wall of the base 110. That is, the base 110 is narrower than the outer panels in the width direction of the unit body. Thus, a certain gap channel is formed between the outer panels of the unit body and the side wall of the base 110 in the width direction. This gap channel extends along the length direction of the unit body, which can further increase the air intake path. Even if the panels on both sides of the width of the unit body are set against the wall, a certain air intake gap can still be formed at the bottom, which, in conjunction with the recessed area 181, fully guarantees the air intake space at the bottom. Correspondingly, an opening groove 183 is also provided on the bottom surface of the base 110 at the position corresponding to the recessed area 181. The opening groove 183 does not penetrate through the bottom surface of the base 110, thus forming a thin-walled connecting plate 184 on the side wall of the base 110 between the opening groove 183 and the recessed area 181. The recessed area 181 is between the connecting plate 184 and the ventilation plate 182. With this design, the connecting plate 184 also acts as a reinforcing plate to ensure structural strength, and the opening groove 183 facilitates the processing and forming of the thin-walled connecting plate 184, ensuring the forming quality of the connecting plate 184 when the base 110 is integrally formed.

[0043] In this embodiment, the air intake duct 180 extends along the length of the unit body, and its extension length covers the extension length of the cooling duct module 600 within the unit body, thereby ensuring comprehensive and sufficient ventilation and heat dissipation. Specifically, regarding the secondary air intake duct 115, in conjunction with... Figures 11-13 As shown, an outwardly extending outer edge plate 116 is provided on the side wall of the base 110 above the recessed area 181. The bottom of the outer panel is supported on the outer edge plate 116, and there is an air intake gap between the secondary air intake channel 115 and the outer panel of the machine body. When the outer panel is not installed, the secondary air intake channel 115 is directly connected to the outside and can fully intake air. When the outer panel is installed, although it blocks the secondary air intake channel 115, there is still a certain gap between the secondary air intake channel 115 and the outer panel. When the cooling fan 602 is started, the airflow around the inside of the machine body can still flow into the interior through the secondary air intake channel 115, which works with the air intake channel 180 to achieve auxiliary air intake and improve the heat dissipation effect.

[0044] Furthermore, the preferred design features a bottom support plate 176 at the bottom of the cooling tank installation area 160, supporting the cooling tank module 600. The bottom support plate 176 has multiple through openings 177, and the bottom of the mounting frame 100, located below the bottom support plate 176, also has legs 178 at a certain height that contact the base 110. This creates a certain height gap between the bottom of the cooling tank module 600 and the base 110, forming an air intake cavity for the cooling tank module 600. A ventilation and heat dissipation path is formed between the through openings 177 and the bottom surface of the cooling tank module 600, further ensuring heat dissipation. Additionally, the bottom of the outer panel where the heat dissipation channel 105 is located on the water dispenser body has an outwardly extending protruding column 104. The protruding column 104 extends beyond the outer panel of the machine body, effectively preventing impact during installation and avoiding direct collision with the machine body panel. The protruding column 104 also prevents direct contact between the wall where the heat dissipation channel 105 is located and the mounting wall, ensuring a sufficient gap for ventilation and guaranteeing heat dissipation.

Thanks to the teachings of this utility model, those skilled in the art will readily recognize that alternative structures to the disclosed structure can be used as feasible alternative implementations, and that the disclosed implementations can be combined to produce new implementations, which also fall within the scope of the appended claims.
