Fig. 11 shows the installation process of the water pan. When the water-collecting tray is installed, the hook can be hooked on the clamping shaft 129 (for example, the position and the state of the water-collecting tray are shown by 160 '), then the front end of the water-collecting tray is lifted upwards, and the front end of the water-collecting tray is fixed at the front end of the ice maker (for example, the position and the state of the water-collecting tray are shown by 160'). After the installation, the front end of the drip tray 160 is higher than the rear end of the drip tray 160. Specifically, the front end of the water pan can be fixed at the front end of the ice maker through screws and the like.

In order to realize rapid ice making of the ice maker 120, the refrigerant pipe 131 is disposed at a lower portion of the ice tray 121 of the ice maker 120 and is in thermal contact with the ice tray 121 of the ice maker.

In some embodiments of the present application, the refrigerant tube 131 may be in direct contact with the bottom of the ice grid 121 of the ice maker.

In some embodiments of the present application, refrigerant tube 131 may be in contact with ice grid 121 of the ice making machine through a thermally conductive material.

For good thermal contact of refrigerant tubes 131 and ice grid 121. An ice making compartment refrigerant line bracket 136 is provided in certain embodiments of the present application. The ice making compartment refrigerant pipe bracket 136 may be fixed to the ice maker by a screw 137, so that the ice making compartment refrigerant pipe 131 between the ice maker 120 and the ice making compartment refrigerant pipe bracket 136 is fixed in a press-fit manner. Specifically, in some embodiments, the ice making compartment refrigerant pipe 131 is press-fit between the ice making compartment refrigerant pipe bracket 136 and the bottom of the ice tray 121, and is in direct contact with the ice tray 121 or in contact with the ice tray 121 through a heat conductive material.

In order to promote the thermal circulation of the entire ice making compartment, an ice making fan compartment 150 is further provided at the front end of the ice maker 120 with an ice making fan 151. The ice making compartment refrigerant pipe bracket is a U-shaped bracket, and an air guide pipe is formed between the inner surface of the ice making compartment refrigerant pipe bracket 136 and the ice maker 120. The rear end of the air guide duct is open, forming an opening 1362. The front end of the air guide duct is communicated with the ice making fan compartment through an air inlet 152 of the ice making fan compartment. An air inlet 152 is formed at the rear side of the ice making fan compartment 150 below the ice maker. An air outlet 153 is formed in front of the ice-making fan compartment 150. After the fan runs, the ice making fan chamber continuously sucks air from the air guide pipeline and blows the air forwards. The air blown out from the ice making compartment blows to the front wall of the ice making compartment and then spreads in all directions, mainly spreading downward. And then exchanges heat with different parts such as an ice bank, an ice crushing chamber and the like in the whole ice making chamber. When the ice making chamber refrigerant pipeline normally runs, the temperature of the ice making chamber refrigerant pipeline is low, heat exchange is carried out between the space sucked from the air guide pipeline and the ice making chamber refrigerant pipeline, and the temperature is relatively low. After being blown out by the ice making fan, the ice making air is diffused to different sections, and the cooling of the whole ice making chamber space is promoted.

To better promote the circulation of air, a plurality of openings are opened at the bottom of the refrigerant pipe bracket 136 of the ice making chamber, and air can enter the diversion pipe through the opening 1361 at the bottom of the pipe bracket 136. After the water tray 160 is installed, the ice making chamber refrigerant pipe bracket 136 is positioned between the water tray 160 and the ice maker 120. The bottom of the ice making chamber refrigerant pipeline bracket 136 is opened with a plurality of openings facing the water receiving tray 160. Air can enter the diversion pipeline through the opening 1361 in the bottom of the pipeline bracket 136, so that the air flow near the water-receiving tray 160 is indirectly promoted, and the possibility of frost formation of the water-receiving tray 160 is reduced.

The second ice blocking plate 180 is provided with a second ventilation opening 181, and the second ventilation opening 181 may include a plurality of ventilation openings. The size of each second ventilation opening is smaller than that of the ice-making grid so as to ensure that ice blocks made by the ice-making grid cannot pass through the second ventilation openings. Through the second ventilation opening 181, air can circulate between the crushed ice compartment 1180 and the ice bank 119.

An air inlet 152 is formed at the rear side of the ice making fan compartment 150 below the ice maker. An air outlet 153 is formed in front of the ice-making fan compartment 150.

An ice feeder is provided in the ice bank 119 to feed ice toward the crushing compartment 1180 on the front side. The ice enters the crushed ice compartment 1180 through an ice inlet of the crushed ice compartment 1180. Due to the arrangement of the second ice baffle 180, on one hand, the normal opening size of the ice inlet of the crushed ice compartment 1180 is ensured, and when the ice crushing device of the crushed ice compartment 1180 works due to overlarge size, ice blocks return to the ice storage box 119 from the crushed ice compartment 1180. Meanwhile, the second vent 181 is formed through the second ice blocking plate 180, so that air blown out from the ice making compartment can enter the crushed ice compartment 1180 through the second vent 181, and the flow rate is increased.

In some embodiments, the refrigerant line 131 passes through the refrigerator liner 15 and enters the ice making compartment after passing through the ice making compartment rear sidewall 115. The rear side wall of the ice making compartment is provided with a first duct 1151 extending toward the front of the ice making compartment, and the first duct 1151 extends from the inside of the base plate 1150 of the rear side wall 115 toward the front of the ice making compartment.

The cross-sections of the lower protector 133 and the upper protector 134 perpendicular to the extending direction of the refrigerant pipe line are gradually reduced in size to match the first guide pipe 1151. Since the size of the cross-section of the first guide pipe 1151 perpendicular to the extending direction of the refrigerant pipe is gradually reduced, when the protector is inserted into the first guide pipe, the insertion depth of the protector is limited, thereby achieving the limitation of the upper, lower, left, right, and front sides of the insert and the ice making compartment refrigerant pipe.

In some embodiments, the water-in-use waterway system operates as follows:

1) when the water path control system of the refrigerator receives a drinking water instruction, the external water valve 210 and the water storage tank 260 are opened corresponding to the water outlet pipe 262, and the external water flows to the external water valve 210, the filter part 240, the water storage tank 250 and the water outlet pipe 262 of the water valve B in sequence under the action of water pressure and finally flows out of the water outlet of the water dispenser assembly 300.

2) When the water channel control system of the refrigerator receives an ice-making water injection instruction, the valves of the external water valve 210 and the water storage tank water valve 260 corresponding to the water outlet pipe 263 are opened, the external water flows to the external water valve 210, the filter part 240, the water storage tank 250 and the water outlet pipe 263 of the water storage tank water valve 260 in sequence under the action of water pressure, finally flows out from the water injection port of the ice-making chamber 100 and enters the ice-making machine to make ice.

3) When the refrigerator waterway control system receives drinking water and ice making water injection instructions at the same time, the valves of the external water valve 210 and the water storage tank water valve 260 corresponding to the water outlet pipe 262 and the water outlet pipe 263 are all opened, the external water flows to the external water valve 210, the filter part 240, the water storage tank 250 and the water outlet pipe 262 and the water outlet pipe 263 of the water storage tank water valve 260 in sequence under the action of water pressure, and cold water flows out from the water outlet of the water dispenser assembly 300 and the water injection port of the ice making chamber 100 respectively.

The above is the basic control logic of the parts of the waterway system when the ice making and drinking module works. In the above process, after the low-temperature water pre-cooled in the tank 251 flows out of the water dispenser assembly 300 and/or the ice making chamber 100, the externally-connected high-temperature hot water enters the water storage tank 250, and at this time, the tank 251 is heated and expands, and the volume is increased; then, as the temperature in the refrigerating compartment is reduced, the tank 251 shrinks and the volume is reduced. When hot water enters, a part of water stored in the tank body is expanded and increased when the tank body is heated, flows to a water outlet pipe 253 of the water storage tank in the process of contraction when the tank body is cooled, and is discharged through a water outlet pipe 262 and a water outlet pipe 263 of a water valve 260 of the water storage tank. Wherein the water outlet leading to the water dispenser component can generate the water seepage problem of the drinking water port when being discharged. Since the temperature of the region where the ice making function module is located is lower than 0 ℃, a problem of freezing and blocking of the water filling port may occur when the water filling port leading to the ice making chamber 100 is discharged.

In this embodiment, a water storage tank water valve 260 is disposed behind the water storage tank 250, and when water taking/ice making and water injection are completed, the water storage tank water valve 260 is closed to seal the water outlet pipe 253 from the water storage tank water outlet pipe 253 to the water outlet pipe 262 of the water storage tank water valve 260 respectively communicated with the water dispenser assembly 300 and the water outlet pipe 263 of the water storage tank water valve 260 communicated with the water injection port of the ice making chamber 100, so as to prevent water extruded due to thermal expansion and contraction of the water storage tank from leaking from the water outlet port of the water dispenser and/or the water injection port of the ice maker.

In some embodiments of the present application, two or more water valves are provided in the water supply system, and after the water supply is completed, the closing time intervals between the water valves have a priority requirement. That is, the water storage tank 210 before the water storage tank 250 is closed, and the water storage tank valve 260 after the water storage tank 250 is closed after a first time interval, so that a part of the water in the tank 251 is discharged by inertia.

Because the water storage tank 250 is provided with the water storage tank water valve 260, after the drinking water pre-cooled and cooled in the tank 251 is discharged, the externally connected high-temperature hot water enters the tank 251, the tank 251 expands after being heated, and then the tank 251 can contract along with the reduction of the temperature in the refrigerating chamber. Since the water supply line from the water storage tank 251 is closed by the water valve 260, a certain internal pressure is generated in the tank 251. Along with the prolonging of the time interval, the internal pressure generated in the process is gradually increased, and stress impact is generated on waterway parts such as the water storage tank 250 and the like; as the number of times of water intake/ice making/water injection is accumulated, the stress shock is continuously generated and accumulated, thereby reducing the durability of the water storage tank 250 and other waterway components connected thereto. The durability of the waterway parts is prevented from being damaged by the internal pressure generated by the water storage tank 250 expanding with heat and contracting with cold. The value of the first time interval is related to the relative position relationship between the front and the back water valves, the layout of the water supply pipeline and other factors.

For the refrigerator with the automatic water drinking function, the problems of incomplete water flow and water dripping after water taking are always the chronic diseases which plague the products. One of the key reasons is the accumulation of gas in the parts of the water supply system or the water supply lines, for example, due to the inability to evacuate bubbles from the water. After external water is injected into a water supply system, bubbles are mixed in water flow, so that the water flow at the water outlet of the water dispenser is discontinuous and incomplete, and the problems of incomplete water flow and water dripping after water taking are further caused. Research shows that the water path part which is most easy to cause air trapping problem is the water storage tank.

Certain embodiments of the present application. The water storage tank inlet 254 is located below the water storage tank outlet 255, and when water is first filled, the tank 251 is sequentially filled with water from bottom to top, so that air in the tank 251 is guaranteed to be discharged before the water is filled.

In some embodiments of the present application, the water outlet 255 is disposed at the highest position of the tank 251, that is, after the water storage tank 250 is assembled and fixed, the area near the water outlet 255 has no point which is equal to or higher than the water outlet. To achieve this effect, the assembly fixing position of the water storage tank 250 is very critical. The relative position of the water outlet 255 on the tank body 251 needs to be fully considered, and the relative position of the water storage tank 250 and the bottom surface of the refrigerator liner needs to be reasonably designed.

In some embodiments, the water tank 251 is a cylinder with two spherical ends. The can 251 is placed obliquely in the refrigerating compartment 10 a. The water outlet 255 is located on a hemispherical portion of the upper end of the can 251.

In some embodiments, the water storage tank 251 is a cylinder with two spherical ends. The water storage tank body 251 is placed in the refrigerating chamber 10a with inclination. The lower end of the water storage tank body 251 is placed at the bottom of the refrigerating chamber. The water outlet 255 is located on a hemispherical portion of the upper end of the can 251. The included angle between the central axis of the water storage tank body 251 and the bottom surface of the tank container is alpha, after the water storage tank 250 is assembled and fixed, the water outlet 255 is positioned at the highest point of the tank body 251, and no point which is equal to or higher than the water outlet exists in the adjacent area. The value of alpha needs to comprehensively consider factors such as the structure of the water storage tank 250, the bottom surface space of the refrigerating chamber liner, the relative position of the water storage tank 250 assembled and fixed on the bottom surface of the refrigerating chamber liner and the like, and preferably takes a large value on the premise of not influencing the assembly performance and the manufacturability, and the recommended value is that alpha is more than or equal to 5 degrees. When water is injected, the water outlet 255 is the last point filled by the water surface, and bubbles in the water storage tank body 251 are ensured to be drained completely; when water is taken, external water flows into the tank body 251 through the water inlet 254, and the highest point of the water surface is firstly discharged from the water outlet 255, so that the problems of incomplete water flow and water dripping after water is taken are solved.

For the refrigerator with the automatic ice making or drinking functional module, because the external water source of the refrigerator is directly connected with the household water delivery system, when the water pressure of the water delivery system is unstable, parts of the water path system can be impacted by continuous water pressure along with the fluctuation of the water pressure, and the durability of the parts is reduced. In some embodiments, an external water valve 210 is added between the external water source and the filter member 240. In a non-working state (no water intake/ice making and water injection), the external water source and the refrigerator waterway system are sealed by the external water valve 210, so that key parts of the waterway (such as the water storage tank 250, the filter part 240 and the like) are protected from impact of water pressure fluctuation.

In some embodiments of the present application, the pre-cooled chilled water in the water storage tank 250 is supplied to both the water dispenser assembly 300 and the ice-making chamber 100.

In some embodiments of the present application, as shown in fig. 17B, the cold water cooled by pre-cooling in the water storage tank is separately supplied to the water dispenser assembly, so as to reduce the interference of the externally connected high-temperature hot water newly injected during the ice making and water injection to the temperature of the cold water. And a filter water valve is arranged behind the filter assembly and is respectively communicated with the ice maker and the water storage tank. When the filter water valve is communicated with the water storage tank, water flowing out of the filter flows into the water storage tank, and then can flow to the water dispenser assembly through the water storage tank. A water storage tank-water dispenser valve is arranged between the water storage tank and the water dispenser component and is used for controlling the water storage tank to be communicated or closed to the water path of the water dispenser component.

In some embodiments of the present application, the closing time interval between the filter water valve and the water storage tank-water dispenser water valve has a precedence requirement. Namely, the water valve of the filter is closed firstly, and then the water valve of the water storage tank and the water dispenser is closed after a second time interval delta t.

In some embodiments of the present application, the closing time interval between the filter water valve before the water storage tank 5 and the external water valve is not particularly required, both can be closed at the same time,

in some embodiments of the present application, the external water valve may be closed first, and the filter water valve may be closed after a third time interval Δ t'.

In some embodiments of the present application, the water supply system includes a filter member 4, as shown in fig. 17A and 17B.

As shown in fig. 17C and 17D, in some embodiments of the present application, the filter member 4 is absent from the water supply system. In particular, when the water filtration and purification device is installed in the household water delivery system of the user, the filter part in the water path system can be eliminated.

As shown in fig. 17-3, in certain embodiments of the present application, chilled water is supplied to both the water dispenser assembly and the ice maker assembly while the water storage tank is pre-cooled. The external water valve is communicated with a water storage tank, and the water storage tank is respectively communicated with the ice maker of the water dispenser assembly through the water valve of the water storage tank. Water in the external water source flows to the water storage tank through the external water valve and then flows to the water valve of the water storage tank, and is divided into two paths after passing through the water valve of the water storage tank, wherein one path of water is communicated to the water dispenser assembly, and the other path of water is communicated to the ice machine.

In some embodiments of the present application, the closing time interval between the external water valve and the water storage tank water valve has a precedence requirement. Namely, the external water valve in front of the water storage tank is closed first, and after the fourth time interval, the water valve of the water storage tank is closed.

As shown in fig. 17D, in some embodiments of the present application, the external water valve is in communication with the ice maker and the water storage tank, respectively, and the water storage tank is in communication with the water storage tank-water dispenser valve. The cold water pre-cooled in the water storage tank is separately supplied to the water dispenser component. The water in the external water source flows into the external water receiving valve and is divided into two paths after passing through the external water valve B, one path is directly led to the ice maker, and the other path is led to the water storage tank, flows to the water storage tank and the water dispenser valve through the water storage tank and further flows to the water dispenser assembly.

In some embodiments of the present application, the closing time interval between the water storage tank-water dispenser water valve and the external water valve has a precedence requirement. Namely, the external water receiving valve in front of the water storage tank is closed firstly, and after a fifth time interval, the water valve in the water storage tank-the water dispenser valve behind the water storage tank is closed.
