Description

Technical Field

[0001] The present application relates to the technical field of ice bladders, and in particular to an ice bladder device, a water system of a coffee machine, and a coffee machine. Background Art

[0002] At present, the water in the ice tank of the coffee machine on the market is cooled quantitatively, and the cooled ice water is used to brew coffee. After the ice water in the ice tank is used up, normal temperature water is added to the ice tank and it can be used after the cooling is completed. This results in a long cooling time, a limited number of coffee making times, and the inability to brew ice coffee continuously at a constant temperature. For example, the Chinese utility model patent with announcement number CN220695030U discloses an ice tank device for a pressure coffee machine, including an ice tank and an evaporation tube for refrigeration, a closed water storage chamber is formed in the ice tank, and the evaporation tube is provided in the water storage chamber. Because there is only one water storage chamber, coffee can only be brewed after the water in the water storage chamber is cooled to ice water, and continuous constant temperature water output cannot be achieved.

[0021] The circulating water inlet is arranged at the upper part of the side wall of the outer ice bladder body, and the first water inlet is arranged on the bottom wall of the inner ice bladder body, so that the normal temperature water entering the outer ice bladder body will not directly enter the inner ice bladder body to affect the temperature of the ice water in the inner ice bladder body, thereby better ensuring that the inner ice bladder body continuously discharges ice water at a constant temperature.

[0022] In some embodiments, a second exhaust port is provided at the upper portion of the side wall of the inner ice bladder body, and the second exhaust port is connected to the inner cavity and the outer cavity so that the water levels in the inner cavity and the outer cavity can be balanced.

[0055] The above and other aspects, features and advantages of the present application will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.

[0056] Specific embodiments of the present application are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present application, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present application. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as a basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of ways with substantially any suitable detailed structure.

[0057] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present application.

[0058] In order to solve the problems in the background technology, the present application provides an ice bladder device, which includes an ice bladder and an evaporating tube for refrigeration. The evaporating tube can be connected to the refrigerant pipeline of the compressor, so that the refrigerant is continuously transported to the evaporating tube by the compressor, and then the cold energy is released through the evaporating tube, thereby realizing the cooling of the water in the ice bladder to produce ice water.

[0059] like Figure 1 , Figure 2 and Figure 3 As shown, the ice bladder includes an inner ice bladder body 1 and an outer ice bladder body 2 which are interconnected, and the inner ice bladder body 1 is located inside the outer ice bladder body 2. Room temperature water or water of other temperatures can be introduced into the outer ice bladder body 2, and the water in the outer ice bladder body 2 can enter the inner ice bladder body 1 which is connected to the outer ice bladder body 2. Evaporation tubes are provided in both the inner ice bladder body 1 and the outer ice bladder body 2, so that the evaporation tubes can cool the water in the inner ice bladder body 1 and the outer ice bladder body 2 at the same time, so as to improve the efficiency of the ice bladder device in making ice water and shorten the time of making ice water.

[0060] The outer ice liner body 2 is provided with a circulating water inlet 201, which is connected to the water pump 13. After the water pump 13 is started, water at room temperature or other temperatures can be introduced into the outer ice liner body 2 through the circulating water inlet 201. For example, the water pump 13 can be connected to a water tank 14 filled with water at room temperature to pump the water in the water tank 14 into the outer ice liner body 2.

[0061] The inner ice bladder body 1 is provided with a first water inlet 101 connecting the inner ice bladder body 1 and the outer ice bladder body 2, so that the water in the outer ice bladder body 2 can enter the inner ice bladder body 1 through the first water inlet 101. The ice bladder device has a water outlet 3 connected with the inner ice bladder body 1, and the water in the inner ice bladder body 1 can be discharged from the inner ice bladder body 1 through the water outlet 3, wherein the water temperature in the inner ice bladder body 1 is lower than the water temperature in the outer ice bladder body 2.

[0062] The circulating water inlet 201 provided on the outer ice bladder body 2 and the first water inlet 101 provided on the inner ice bladder body 1 can be arranged alternately, and the two can have a certain height difference. When there is ice water in the outer ice bladder body 2 and the inner ice bladder body 1, the normal temperature water entering the outer ice bladder body 2 can circulate in the outer ice bladder body 2 for a certain period of time and mix with the existing ice water in the outer ice bladder body 2, and then enter the inner ice bladder body 1 through the first water inlet 101, and will not directly enter the inner ice bladder body 1 to affect the temperature of the ice water in the inner ice bladder body 1. Moreover, when normal temperature water is passed into the outer ice bladder body 2, the ice water in the inner ice bladder body 1 can also continue to provide constant temperature ice water through the water outlet 3 connected thereto. That is, the water with higher water temperature in the outer ice bladder body 2 will not directly affect the temperature of the ice water with lower water temperature in the inner ice bladder body 1 when normal temperature water is passed into the outer ice bladder body 2.

[0063] The ice bladder of the embodiment of the present application includes an inner ice bladder body 1 and an outer ice bladder body 2. The inner ice bladder body 1 and the outer ice bladder body 2 are both provided with evaporation tubes for refrigeration, so as to cool down the water in the inner ice bladder body 1 and the outer ice bladder body 2 at the same time. The outer ice bladder body 2 can take in water at room temperature, and the water in the outer ice bladder body 2 can enter the inner ice bladder body 1 through the first water inlet 101. The inner ice bladder body 1 can continuously provide constant temperature ice water, and the ice water can be used to brew ice coffee or drink directly. The two bladders are cooled at the same time, which can shorten the time of making ice water, and ice water can be continuously provided through the inner ice bladder body 1, shortening the waiting time of users.

[0064] In some embodiments, in combination Figure 3 The top of the outer ice bladder body 2 and the top of the inner ice bladder body 1 are both open.

[0065] Combination Figure 2 The ice bladder device also includes a top cover 4, which is arranged on the top of the outer ice bladder body 2, and the top cover 4 can block the opening at the top of the outer ice bladder body 2 and the opening at the top of the inner ice bladder body 1. The top cover 4 and the outer ice bladder body 2 are enclosed to form an outer cavity 202, and the top cover 4 and the inner ice bladder body 1 are enclosed to form an inner cavity 102. The top cover 4 is respectively enclosed with the outer ice bladder body 2 and the inner ice bladder body 1 to form the outer cavity 202 and the inner cavity 102, so that the ice bladder has two water storage cavities that are interconnected but have different water temperatures. Even when normal temperature water is passed into the outer cavity 202, the normal temperature water in the outer cavity 202 will not immediately affect the temperature of the ice water in the inner cavity 102, so that the ice bladder device can achieve continuous constant temperature ice water output.

[0066] The top cover 4 can be fixed to the outer ice bladder body 2 in a detachable manner, or can be set on the outer ice bladder body 2 by welding to prevent leakage of the inner cavity 102 and the outer cavity 202 at the position of the top cover 4. The detachable fixing method can be, but is not limited to, threaded fitting, snap fitting, etc.

[0067] In some embodiments, the upper portion of the outer ice bladder body 2 is provided with a first exhaust port 203 connected to the outside. Figure 8 , the first exhaust port 203 and the water outlet 3 can both be arranged on the top cover 4. Of course, it can be understood that the first exhaust port 203 can also be arranged on the upper part of the side wall of the outer ice bladder body 2, which is only used as an example and does not constitute a limitation on the protection scope of the claims. The first exhaust port 203 can exhaust the outer cavity 202 when water is passed into the outer cavity 202, release the pressure of the outer cavity 202, and avoid excessive pressure in the outer cavity 202.

[0068] In some embodiments, in combination Figure 1 , Figure 2 and Figure 3 The ice bladder device also includes a temperature sensor 5 for detecting the water temperature in the inner cavity 102, and the temperature sensor 5 is arranged on the top cover 4. The temperature sensor 5 can be, but is not limited to, an NTC (negative temperature coefficient thermistor). The temperature sensor 5 is used to measure the water temperature in the inner cavity 102 to determine whether the water temperature in the inner cavity 102 reaches the temperature requirement for producing ice water, so as to better meet the user's demand for ice water.

[0069] In some embodiments, Figure 8 As shown, the top cover 4 is provided with a first mounting hole 401, a second mounting hole 402 and a third mounting hole 403, the outer ice bladder body 2 is provided with a fourth mounting hole 204, and the fourth mounting hole 204 can be provided on the bottom wall or the side wall of the outer ice bladder body 2.

[0070] like Figure 2 , Figure 4 and Figure 5 As shown, the evaporation tube includes an inner evaporation tube 6 and an outer evaporation tube 7. The inner evaporation tube 6 is arranged in the inner cavity 102, and one end thereof extends from the inner cavity 102 through the first mounting hole 401 and communicates with the refrigerant introduction pipe (not shown in the figure), and the other end of the inner evaporation tube 6 extends from the inner cavity 102 through the second mounting hole 402. Specifically, the inner evaporation tube 6 can be arranged in the inner cavity 102 in a spiral shape. The outer evaporation tube 7 is arranged in the outer cavity 202, and one end thereof extends from the outer cavity 202 through the third mounting hole 403 and communicates with the other end of the inner evaporation tube 6, combined with Figure 6, the other end of the outer evaporator tube 7 extends from the outer cavity 202 through the fourth mounting hole 204 and is connected to the refrigerant outlet pipe (not shown in the figure). Specifically, the outer evaporator tube 7 can be arranged in the outer cavity 202 in a spiral shape, and the outer evaporator tube 7 is arranged in a spiral around the outer side of the inner ice bladder body 1. The refrigerant inlet pipe and the refrigerant outlet pipe are respectively connected to the compressor. The refrigerant inlet pipe first transports the refrigerant to the inner evaporator tube 6. At this time, the refrigerant entering the inner evaporator tube 6 has a lower temperature of cold energy than the refrigerant entering the outer evaporator tube 7 after passing through the inner evaporator tube 6, so as to cool the water in the inner cavity 102 more quickly. Of course, the refrigerant inlet pipe can also be connected to the outer evaporator tube 7, and the refrigerant outlet pipe can be connected to the inner evaporator tube 6. This is only used as an example and does not constitute a limitation on the scope of protection of the claims. The inner evaporator tube 6 and the outer evaporator tube 7 can be sealed and fixed at the first mounting hole 401, the second mounting hole 402, the third mounting hole 403 and the fourth mounting hole 204. For example, but not limited to, welding sealing can be used to prevent water in the inner cavity 102 and the outer cavity 202 from leaking.

[0071] The inner evaporator tube 6 and the outer evaporator tube 7 respectively installed in the inner cavity 102 and the outer cavity 202 are connected to each other to achieve simultaneous cooling of the water in the inner cavity 102 and the water in the outer cavity 202, and the inner evaporator tube 6 is connected to the refrigerant inlet pipe, and the outer evaporator tube 7 is connected to the refrigerant outlet pipe, so that the refrigerant can cool the water in the inner cavity 102 that directly discharges ice water more quickly.

[0072] In some embodiments, the outer bottom surface of the inner ice bladder body 1 is located above the inner bottom surface of the outer ice bladder body 2 and the two are spaced apart.

[0073] Combination Figure 7 The circulating water inlet 201 is arranged at the upper part of the side wall of the outer ice bladder body 2.

[0074] Combination Fig. 9 The first water inlet 101 is arranged on the bottom wall of the inner ice bladder body 1.

[0075] The outer bottom surface of the inner ice bladder body 1 is located above the inner bottom surface of the outer ice bladder body 2, and is arranged at intervals, so that the first water inlet 101 can be arranged on the bottom wall of the inner ice bladder body 1. The circulating water inlet 201 is arranged at the upper part of the side wall of the outer ice bladder body 2, and the first water inlet 101 is arranged on the bottom wall of the inner ice bladder body 1, so that the normal temperature water entering the outer ice bladder body 2 will not directly enter the inner ice bladder body 1 to affect the temperature of the ice water in the inner ice bladder body 1, but first enters the inner cavity 102 after being cooled by the outer evaporation tube 7 in the outer cavity 202, which better ensures that the inner ice bladder body 1 continuously outputs constant temperature ice water.

[0076] In some embodiments, the Fig. 9The upper part of the side wall of the inner ice bladder body 1 is provided with a second exhaust port 103, which connects the inner cavity 102 and the outer cavity 202, so that the water levels in the inner cavity 102 and the outer cavity 202 can be balanced. The second exhaust port 103 can balance the air pressure in the inner ice bladder body 1 and the outer ice bladder body 2, and prevent the different air pressures from affecting the water discharge of the ice bladder.

[0077] In some embodiments, in combination Figure 2 and Figure 3 The ice bladder device also includes a first one-way valve, which is arranged on the circulating water inlet 201 so that water can flow into the outer ice bladder body 2 through the first one-way valve in one direction. The first one-way valve can only allow water to flow into the outer ice bladder body 2, but cannot allow the outer ice bladder body 2 to flow out. In this way, it can be prevented that when making ice water out of the ice bladder, the pressure in the ice bladder increases and damages the ice bladder device.

[0078] The first one-way valve may be a spring-type one-way valve. For example, the first one-way valve includes a valve core 801 and a spring 802 disposed on the valve core 801. The valve core 801 and the spring 802 are both disposed in the circulating water inlet 201. A pipe joint 9 may also be disposed at the circulating water inlet 201. The pipe joint 9 is sealed and connected to the circulating water inlet 201 via a sealing ring. For example, one end of the pipe joint 9 is disposed in the circulating water inlet 201, a first pipe opening of the pipe joint 9 is located in the circulating water inlet 201, and a second pipe opening of the pipe joint 9 is located outside the circulating water inlet 202. The valve core 801 is blocked at the first pipe opening of the pipe joint 9 under the action of the spring 802 to prevent the water in the outer ice bladder body 2 from flowing out through the pipe joint 9. When the water pump 13 starts to deliver water to the outer ice bladder body 2 through the pipe joint 9 and the circulating water inlet 201, under the action of the water pressure, the valve core 801 of the first one-way valve is flushed away from the pipe opening of the pipe joint 9 located in the circulating water inlet 201 to open the circulating water inlet 201 and realize one-way water inlet. Of course, it can be understood that the first one-way valve can also adopt a one-way valve structure of other structural forms, which is only used as an example and does not constitute a limitation on the protection scope of the claims.

[0079] The present application also provides a water system for a coffee machine, such as Fig.10 As shown, the water system of the coffee machine includes a circulation component and an ice container device as described in any of the above embodiments.

[0080] Combination Figure 7 A second water inlet 205 is also provided on the outer ice bladder body 2 of the ice bladder device.

[0081] The circulation component includes a three-way solenoid valve 10, a circulation pump 11 and a second one-way valve 12. The first port of the three-way solenoid valve 10 is connected to the water outlet 3 of the ice bladder device, the second port of the three-way solenoid valve 10 is connected to the brewing component 15 of the coffee machine, the third port of the three-way solenoid valve 10 is connected to the water inlet of the circulation pump 11, the water outlet 3 of the circulation pump 11 is connected to the first port of the second one-way valve 12, and the other port of the second one-way valve 12 is connected to the second water inlet 205, so as to send the water in the inner ice bladder body 1 into the outer ice bladder body 2. When the outer ice bladder body 2 starts to take in water, the circulation pump 11 works, the first port and the third port of the three-way solenoid valve 10 are connected, and when the ice bladder device is filled with water, after the circulation pump 11 pumps water, its load current increases, and at this time, the water pump 13 that pumps water for the ice bladder device can be disconnected. Specifically, the circulation component can be used to measure the water level of the ice bladder device and the water in the circulating inner ice bladder body 1 and the outer ice bladder body 2. The circulation pump 11 draws water from the inner ice bladder body 1 and sends it to the outer ice bladder body 2. When the water level of the outer ice bladder body 2 is higher than the first water inlet 101, suction will be generated, resulting in no water in the outer ice bladder body 2. At this time, the second exhaust port 103 of the inner ice bladder body 1 can inhale the air in the outer ice bladder body 2, so that the water levels in the inner ice bladder body 1 and the outer ice bladder body 2 can be kept balanced and filled with water until full.

[0082] After the ice bladder device is filled with water, the evaporation tube can be started to cool the water in the inner ice bladder body 1 and the outer ice bladder body 2. The water in the inner ice bladder body 1 and the outer ice bladder body 2 can also be cooled when the ice bladder device has a certain water level.
