Description

Technical Field

[0001] This utility model belongs to the technical field of chilled water machines and relates to a chilled water machine. Background Technology

[0002] Household water purifiers are mainly used to purify tap water in the tap so that it can be drunk directly. For ease of placement, most existing water purifiers are installed under the kitchen sink. When users want to drink ice water, they usually put room temperature drinking water in the refrigerator to cool it down, which is too cumbersome and inconvenient.

[0003] To address the aforementioned problems, a Chinese patent application discloses a condenser tank for a built-in evaporator in a water purifier [Authorization Announcement No.: CN204227959U], which includes a condenser tank body. The condenser tank body includes a tank body with a pure water inlet at the top. The pure water inlet is connected to the internal filter element assembly of the water purifier through a drain pipe. A spiral refrigerant flow channel is arranged along the axial direction on the side wall of the tank body, and a refrigerant inlet and a refrigerant outlet are respectively provided at both ends of the refrigerant flow channel.

[0004] The tank sidewall in the above structure is provided with a spiral preparation flow channel along the axial direction, so that drinking water flows along the spiral preparation flow channel and is cooled. However, the cooling effect of this method is poor, and the spiral shape needs to occupy a relatively large space when in use, resulting in a large size of the condenser tank body, which is not convenient for installation and placement. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a chilled water machine. The technical problem to be solved by this utility model is: how to solve the problem of poor cooling effect of existing chilled water machines.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A chilled water machine includes a housing with an installation chamber, a chilled water tank disposed within the housing, and a refrigeration device. The housing has an inlet and an outlet. The chilled water tank has a cooling chamber. The outlet of the chilled water tank is connected to the outlet, and the inlet of the chilled water tank is connected to the inlet. The cooling chamber is characterized by having two sets of partitions arranged alternately along the left and right sides. A refrigeration pipe is disposed within the cooling chamber. The refrigeration pipe has two serpentine curved sections arranged from top to bottom, and the two curved sections are arranged side-by-side along the front-back direction of the chilled water tank. One end of each set of partitions is fixed to the left and right walls of the cooling chamber, respectively, and the other end forms a flow gap with either the left or right wall of the cooling chamber. The bends of the curved sections pass through the flow gap sequentially from top to bottom, and the bottoms of the two curved sections connect.

[0008] By installing refrigeration pipes inside the cold water tank and circulating refrigerant through them, drinking water flows from the inlet of the shell through the inlet of the cold water tank and into the tank. Two sets of baffles are installed inside the cooling chamber, with one end fixed to the left and right walls of the chamber respectively. The baffles are staggered in the left-right direction, and the other end of each baffle forms a flow gap with either the left or right wall of the cooling chamber. The entire cooling chamber forms a serpentine flow path, increasing the flow path of the cooling water and reducing its flow velocity. The refrigeration pipes inside the cooling chamber have two serpentine bends. The bends of these bends pass through the flow gaps from top to bottom. The bottoms of the sections are connected, allowing the refrigerant entering the refrigeration pipe to flow from top to bottom along one of the curved sections, and then flow into another curved section from the bottom where the two curved sections meet. In the other curved section, the refrigerant needs to flow out from bottom to top, reducing the outflow velocity of the refrigerant. By increasing the residence time of the refrigerant and lengthening the flow path, a better cooling effect is achieved, enabling rapid cooling of the drinking water in the cold water tank. Furthermore, the baffle, designed in conjunction with the shape of the refrigeration pipe, allows the drinking water entering the cold water tank to flow along a serpentine path, thereby increasing the contact time and area between the drinking water and the refrigeration pipe, and reducing the flow velocity of the drinking water in the entire cooling tank, thus enabling the drinking water to achieve a better cooling effect.

[0009] In the aforementioned chilled water machine, the inlet and outlet of the refrigeration pipe are both located at the top of the cold water tank, and the outlet of the cold water tank is close to the inlet and outlet of the refrigeration pipe.

[0010] By placing the outlet of the cold water tank close to the inlet and outlet of the refrigeration pipe, the refrigerant that has just entered the refrigeration pipe can quickly cool the ice water at the outlet again, thus enhancing its cooling effect.

[0011] In the aforementioned chilled water machine, the inlet of the chilled water tank is located on one side of the lower end of the chilled water tank, and the outlet of the chilled water tank is located on the other side of the upper end of the chilled water tank.

[0012] The design of the inlet and outlet of the cold water tank ensures that the drinking water entering the tank flows slowly from the bottom to the top, thus guaranteeing the cooling effect of the drinking water.

[0013] In the aforementioned chilled water machine, all partitions are arranged in parallel, and both the front and rear sides of the partitions are fixedly connected to the inner wall of the chilled water tank.

[0014] By suspending one end of the partition and fixing both the front and rear sides of the partition to the inner wall of the cold water tank, the partition can divide the cold water tank into multiple interconnected cooling chambers from top to bottom. The parallel arrangement of all the partitions ensures that each cooling chamber is of equal size, which facilitates a stable and slow flow of drinking water, thereby achieving a better cooling effect.

[0015] In the aforementioned chilled water machine, the outlet of the chilled water tank is located between the uppermost partition and the top wall of the chilled water tank, and the inlet of the chilled water tank is located between the lowermost partition and the bottom wall of the chilled water tank.

[0016] This structure ensures that drinking water entering the cold water tank from the inlet flows sequentially along an S-shaped flow path from the bottom cooling chamber, guaranteeing that the drinking water entering the cold water tank is sufficiently cooled.

[0017] In the aforementioned chilled water machine, the chilled water tank includes a rectangular bottom with an opening on one side and a side cover that covers the bottom. The partition has mounting posts at both ends and in the middle. The side cover and the bottom are threadedly connected to the mounting posts by fasteners.

[0018] This structure facilitates the installation and setup of the refrigeration pipes, while also ensuring the stability of the connection between the partition and the side cover, preventing leaks and improving the cooling effect of the chiller.

[0019] In the aforementioned chilled water machine, the refrigeration device includes a compressor and a condenser with a fan, which are installed and connected in the installation chamber. An isolation plate is vertically connected to the bottom of the installation chamber. The condenser and compressor are located on one side of the isolation plate, and the chilled water tank is located on the other side of the isolation plate.

[0020] The partition can isolate components such as the compressor and condenser from the cold water tank, so that the compressor and condenser do not affect each other and reduce the impact on the cold water tank located on the other side of the partition, thereby allowing the cold water in the cold water tank to be better kept warm.

[0021] Compared with existing technologies, this chiller has the following advantages: the refrigerant entering the refrigeration pipes can flow from top to bottom along one bend, and then flow into another bend from the bottom where the two bends meet. In the second bend, the refrigerant needs to flow out from bottom to top, reducing the outflow speed of the refrigerant. By increasing the residence time of the refrigerant and lengthening the flow path, a better cooling effect is achieved, enabling rapid cooling of the drinking water in the cold water tank. Furthermore, the baffles, designed in conjunction with the shape of the refrigeration pipes, allow the drinking water entering the cold water tank to flow along multiple serpentine paths, thereby increasing the contact time and area between the drinking water and the refrigeration pipes, and reducing the flow rate of the drinking water in the entire cooling tank, thus enabling the drinking water to achieve a better cooling effect.

[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] like Figure 1 As shown, this chilled water machine includes a housing 1 with an installation chamber 11, a chilled water tank 2 disposed within the housing 1, and a refrigeration device.

[0030] Specifically, such as Figure 1-5 As shown, the shell 1 has a water inlet 12 and a water outlet 13. The cold water tank 2 has a cooling chamber 21. The water outlet 22 of the cold water tank 2 is connected to the water outlet 13, and the water inlet 23 of the cold water tank 2 is connected to the water inlet 12. The cooling chamber 21 is provided with two sets of partitions 24 arranged alternately from left to right. The cooling chamber 21 is provided with a refrigeration pipe 3. The refrigeration pipe 3 has two curved sections 31 arranged in a serpentine manner from top to bottom. The two curved sections 31 are arranged side by side along the front and back direction of the cold water tank 2. One end of the two sets of partitions 24 is fixed to the left and right walls of the cooling chamber 21, respectively. The other end forms a flow gap 4 between the left or right wall of the cooling chamber 21. The bends of the curved sections 31 pass through the flow gap 4 from top to bottom. The bottoms of the two curved sections 31 are connected.

[0031] A refrigeration pipe 3 is installed inside the cold water tank 2, and refrigerant is introduced into the refrigeration pipe 3. At this time, drinking water flows from the water inlet 12 of the shell 1 through the water inlet 23 of the cold water tank 2 and flows into the cold water tank 2. Two sets of baffles 24 are installed in the cooling chamber 21. One end of the two sets of baffles 24 is fixed to the left and right chamber walls of the cooling chamber 21, respectively, and the two sets of baffles 24 are staggered in the left and right directions. The other end of the baffles 24 forms a flow gap 4 with the left or right chamber wall of the cooling chamber 21. The entire cooling chamber 21 forms a serpentine flow path, which increases the flow path of the cooling water and also reduces the flow velocity of the cooling water. The refrigeration pipe 3 is installed in the cooling chamber 21. The refrigeration pipe 3 has two serpentine curved sections 31. The bends of the curved sections 31 pass through the flow channels from top to bottom. The gap 4 and the bottom of the curved section 31 are connected, so that the refrigerant entering the refrigeration pipe 3 can flow from top to bottom along one curved section 31 and then flow into another curved section 31 from the bottom where the two curved sections 31 are connected. In the other curved section 31, the refrigerant needs to flow out from bottom to top, reducing the outflow speed of the refrigerant. By increasing the residence time of the refrigerant and lengthening the flow path, a better cooling effect is achieved, realizing the rapid cooling of drinking water in the cold water tank 2. In addition, the baffle 24 is set in accordance with the shape of the refrigeration pipe 3, so that the drinking water entering the cold water tank 2 can flow along multiple S-shaped paths, thereby increasing the contact time and area between the drinking water and the refrigeration pipe 3, and also reducing the flow rate of the drinking water in the entire cooling tank 2, so that the drinking water can play a better cooling role.

[0032] The outlet and inlet sections of the refrigeration pipe 3 are both vertically arranged and extend out of the cold water tank 2.

[0033] like Figure 3-5 As shown, the inlet 32 ​​and outlet 33 of the refrigeration pipe 3 are both located at the top of the cold water tank 2. The outlet 22 of the cold water tank 2 is close to the inlet 32 ​​and outlet 33 of the refrigeration pipe 3. The outlet 22 of the cold water tank 2 is located between the uppermost partition 24 and the top wall of the cold water tank 2. The inlet 23 of the cold water tank 2 is located between the lowermost partition 24 and the bottom wall of the cold water tank 2. The inlet 23 of the cold water tank 2 is located on one side of the lower end of the cold water tank 2, and the outlet 22 of the cold water tank 2 is located on the other side of the upper end of the cold water tank 2.

[0034] like Figure 2-5 As shown, all partitions 24 are arranged in parallel. The front and rear sides of the partitions 24 are fixed to the inner wall of the cold water tank 2. The cooling tank 2 includes a rectangular bottom 25 with an opening on one side and a side cover 26 covering the bottom 25. The partitions 24 have mounting posts 24a at both ends and in the middle. The side cover 26 and the bottom 25 are threadedly connected to the mounting posts 24a by fasteners.

[0035] like Figure 1As shown, the refrigeration device 5 includes a compressor 51 and a condenser 52 with a fan 53 installed and connected in the installation chamber 11. An isolation plate 14 is vertically connected to the bottom of the installation chamber 11. The condenser 52 and the compressor 51 are installed on one side of the isolation plate 14, and the cold water tank 2 is installed on the other side of the isolation plate 14.
