Description
本發明是有關於一種飲水機，且特別是有關於一種可穩定供給冰水與熱水的飲水機。The present invention relates to a water dispenser, and more particularly to a water dispenser that can stably supply ice water and hot water.
一般市售飲水機以溫度控制功能分類可分為；溫熱型與冰溫熱型等兩種。冰水溫度約在4~8℃間，溫水溫度指常溫27℃至50℃間，熱水溫度約50~95℃間。習知飲水機的熱水產生方式是利用電熱管直接或間接加熱熱水膽內之飲用水至90℃左右，以獲得飲水機所需之熱水，其缺點在於電熱管的熱交換效率差。飲水機之冰水產生方式則利用壓縮機配合冷卻盤管對冷水膽內飲用水進行製冷處理，其缺點在於冷媒有礙環保目的與壓縮機振動噪音問題。Generally, the commercially available water dispensers can be classified into two types according to the temperature control function classification: warm type and ice type. The temperature of ice water is about 4~8 °C, the temperature of warm water is between 27 °C and 50 °C, and the temperature of hot water is about 50~95 °C. The hot water generation method of the conventional water dispenser is to directly or indirectly heat the drinking water in the hot water bladder to about 90 ° C by using the electric heating pipe to obtain the hot water required by the water dispenser, and the disadvantage is that the heat exchange efficiency of the electric heating pipe is poor. The ice water production method of the water dispenser uses the compressor and the cooling coil to cool the drinking water in the cold water bladder. The disadvantage is that the refrigerant hinders the environmental protection purpose and the vibration noise of the compressor.
近期部分飲水機利用熱電元件達到製造冰水的目的。飲水機使用熱電元件之優點在於製熱或製冷時只需依靠熱電元件中的電子移動，不需要任何機械作動，具有系統穩定及低維修需求的特性，在小型家電領域應用具有極大的潛力。熱電元件用於製熱時，需另外設計致冷側的散熱機制。氣冷式散熱機制是在熱電元件的致冷側貼附散熱鰭片，再以風機進行散熱處理，缺點是散熱效率不佳。水冷式散熱是讓熱電元件之兩側分別貼附於冷水膽與熱水膽上，熱電元件作用時可同時加熱熱水膽中之飲用水及降低冷水膽中飲用水溫度。但是，冷水膽與熱水膽的容積是固定的，當使用者由其中之一水膽中取用飲用水後，晶片兩側之製熱與製冷能力會不平衡而使熱電元件的功能失常，因此市面上目前未見實際之商品販售。Recently, some water dispensers use thermoelectric elements to achieve the purpose of making ice water. The advantage of using the thermoelectric element in the water dispenser is that it only needs to rely on the movement of electrons in the thermoelectric element during heating or cooling, does not require any mechanical action, has the characteristics of system stability and low maintenance demand, and has great potential in the application of small household appliances. When the thermoelectric element is used for heating, the heat dissipation mechanism on the cooling side needs to be additionally designed. The air-cooled heat-dissipating mechanism attaches heat-dissipating fins to the cooling side of the thermoelectric element, and then dissipates heat by the fan. The disadvantage is that the heat-dissipating efficiency is not good. Water-cooled heat dissipation allows the two sides of the thermoelectric element to be attached to the cold water bladder and the hot water bladder respectively. When the thermoelectric element acts, the drinking water in the hot water bladder can be simultaneously heated and the drinking water temperature in the cold water bladder can be lowered. However, the volume of the cold water bladder and the hot water bladder is fixed. When the user takes the drinking water from one of the water bladders, the heating and cooling capacities on both sides of the wafer may be unbalanced, causing the thermoelectric elements to malfunction. Therefore, there is currently no actual sale of goods on the market.

為讓本發明之上述特徵和優點能更明顯易懂，下文特舉實施例，並配合所附圖式作詳細說明如下。The above described features and advantages of the present invention will be more apparent from the following description.
圖1是本發明一實施例的飲水機的示意圖。請參照圖1，本實施例的飲水機1000包括一進水系統1100、一飲用水儲存系統S12、一冷卻水系統1200、一製冷系統1300、一製熱系統1400以及一出水系統1500。飲用水儲存系統S12連通進水系統1100。製冷系統1300連通飲用水儲存系統S12，包括一冷水膽1320與一第一熱電元件1310。第一熱電元件1310之致冷側接觸冷水膽1320。製熱系統1400連通飲用水儲存系統S12，包括一低溫熱水膽1420與一第二熱電元件1410。第二熱電元件1410之致熱側接觸低溫熱水膽1420。冷卻水系統1200連通進水系統1100且連接至第一熱電元件1310之致熱側與第二熱電元件1410之致冷側。出水系統1500連通製熱系統1400與製冷系統1300。1 is a schematic view of a water dispenser according to an embodiment of the present invention. Referring to FIG. 1 , the water dispenser 1000 of the present embodiment includes a water inlet system 1100 , a drinking water storage system S12 , a cooling water system 1200 , a refrigeration system 1300 , a heating system 1400 , and a water outlet system 1500 . The drinking water storage system S12 is connected to the water inlet system 1100. The refrigeration system 1300 is connected to the drinking water storage system S12 and includes a cold water tank 1320 and a first thermoelectric element 1310. The cold side of the first thermoelectric element 1310 contacts the cold water bladder 1320. The heating system 1400 is connected to the drinking water storage system S12 and includes a low temperature hot water tank 1420 and a second thermoelectric element 1410. The heat generating side of the second thermoelectric element 1410 contacts the low temperature hot water bladder 1420. The cooling water system 1200 communicates with the water inlet system 1100 and is coupled to the heating side of the first thermoelectric element 1310 and the refrigeration side of the second thermoelectric element 1410. The water outlet system 1500 communicates with the heating system 1400 and the refrigeration system 1300.
本實施例的飲水機1000中，第一熱電元件1310的致冷側接觸製冷系統1300的冷水膽1320，而第一熱電元件1310的致熱側(散熱側)則連通冷卻水系統1200而接觸常溫的水，以藉由冷卻水系統1200提供的冷卻水將致熱側(散熱側)的熱量帶走而維持第一熱電元件1310的正常運作。因此，第一熱電元件1310可持續且穩定地對製冷系統1300的冷水膽1320作用而產生冰水。另一方面，第二熱電元件1410的致冷側則連通冷卻水系統1200而接觸常溫的水，以藉由冷卻水系統1200提供的冷卻水提供熱量給致冷側來提高致冷側的溫度而維持第一熱電元件1310的正常運作。而第二熱電元件1410的致熱側接觸製熱系統1400的低溫製熱水膽1420。因此，第二熱電元件1410可持續且穩定地對製熱系統1400的低溫製熱水膽1420作用而產生熱水。因為製冷系統1300與製熱系統1400並不共用熱電元件與散熱機制，所以即使從製冷系統1300的冷水膽1320中取出大量冰水，也不會影響製熱系統1400的製熱功能。反之，即使從製熱系統1400的低溫製熱水膽1420中取出大量熱水，也不會影響製冷系統1300的製冷功能。In the water dispenser 1000 of the present embodiment, the cooling side of the first thermoelectric element 1310 contacts the cold water tank 1320 of the refrigeration system 1300, and the heating side (heat dissipation side) of the first thermoelectric element 1310 communicates with the cooling water system 1200 to contact the normal temperature. The water maintains the normal operation of the first thermoelectric element 1310 by taking away the heat of the heat generating side (heat dissipating side) by the cooling water supplied from the cooling water system 1200. Therefore, the first thermoelectric element 1310 can continuously and stably act on the cold water bladder 1320 of the refrigeration system 1300 to generate ice water. On the other hand, the cooling side of the second thermoelectric element 1410 communicates with the cooling water system 1200 to contact the water of normal temperature to provide heat to the cooling side by the cooling water provided by the cooling water system 1200 to increase the temperature of the cooling side. The normal operation of the first thermoelectric element 1310 is maintained. The heat generating side of the second thermoelectric element 1410 contacts the low temperature hot water bladder 1420 of the heating system 1400. Therefore, the second thermoelectric element 1410 can continuously and stably act on the low temperature hot water tank 1420 of the heating system 1400 to generate hot water. Since the refrigeration system 1300 and the heating system 1400 do not share the thermoelectric elements and the heat dissipation mechanism, even if a large amount of ice water is taken out from the cold water tank 1320 of the refrigeration system 1300, the heating function of the heating system 1400 is not affected. On the contrary, even if a large amount of hot water is taken out from the low temperature hot water tank 1420 of the heating system 1400, the cooling function of the refrigeration system 1300 is not affected.
藉此，本實施例的飲水機1000可穩定提供熱水與冰水，而溫水也可由混合熱水與冰水獲得。此外，熱電元件的熱交換效率也優於電熱管與壓縮機，且兼具低噪音、無機械損耗與符合環保要求的優點。藉由適當調控冷卻水系統1200之冷卻水水溫，可同時使第一熱電元件1310與第二熱電元件1410皆處在良好的運作效率下，進行製冷與製熱。Thereby, the water dispenser 1000 of the embodiment can stably provide hot water and ice water, and the warm water can also be obtained by mixing hot water and ice water. In addition, the heat exchange efficiency of the thermoelectric element is also superior to that of the electric heating tube and the compressor, and has the advantages of low noise, no mechanical loss and environmental protection requirements. By appropriately adjusting the cooling water temperature of the cooling water system 1200, both the first thermoelectric element 1310 and the second thermoelectric element 1410 can be simultaneously cooled and heated with good operating efficiency.
本實施例的進水系統1100具有一原水進水頭1110、一淨水進水頭1120與一排水頭1130。然而，在其他實施例中，進水系統也可僅包含單一進水頭或有更多種類的進水頭與排水頭。本實施例的製熱系統1400具有第二熱電元件1410、低溫製熱水膽1420、一高溫製熱水膽1430與一浸水式電熱管1440。本實施例的冷卻水系統1200具有一冷卻水槽1210。本實施例的出水系統1500具有一冰水控制閥1510、一溫水控制閥1520與一熱水控制閥1530，但其他實施例的出水系統也可以僅有兩個出水頭或更多出水頭。冰水控制閥1510連通冷水膽1320。本實施例的飲水機1000還具有一淨水系統1600、多個水泵1700、多根管路1800、多個控制閥1900、多個水位偵測器1910與多個溫度偵測器1920。控制閥1900用以控制水的通過與否，水泵1700則用以加壓輸送水。以下，說明上述元件的連接關係以及部分元件的細部構造。The water inlet system 1100 of the present embodiment has a raw water inlet head 1110, a clean water inlet head 1120 and a drain head 1130.

The cooling water system 1200 of the present embodiment has a cooling water tank 1210. The water outlet system 1500 of the present embodiment has an ice water control valve 1510, a warm water control valve 1520 and a hot water control valve 1530. However, the water outlet system of other embodiments may have only two water outlet heads or more water outlet heads. The ice water control valve 1510 communicates with the cold water bladder 1320.

The control valve 1900 is used to control the passage of water, and the water pump 1700 is used to pressurize the water. Hereinafter, the connection relationship of the above elements and the detailed structure of the partial elements will be described.

The purified water inlet head 1120 is introduced into the drinking water that has been purified by the drinking fountain 1000. The raw water inlet head 1110 is directly connected to the cooling water tank 1210 via the line 1800 and the control valve 1900. The raw water inlet head 1110 is also connected to the water purification system 1600 via the line 1800, and is connected to the cooling water tank 1210 via the line 1800 and the control valve 1900, and is connected to the drinking water storage system S12 via the line 1800. The water entering the cooling water tank 1210 can supplement the shortage of the cooling water, and can also adjust the water temperature of the cooling water. The drain head 1130 is connected to the cooling water tank 1210, the cold water tank 1320 and the high temperature hot water tank 1430 via the pipeline 1800 and the control valve 1900 for discharging the water in the cooling water tank 1210, the cold water tank 1320 and the high temperature hot water tank 1430.

The raw water is sent to the filter cotton filter 1610 to remove sand and microorganisms, and then enters the reverse osmosis membrane filter 1620 through the control valve 1900 to filter bacteria, compounds and heavy metals. Control valve 1900 is here used to control the amount of water stored in the system. Finally, the post-activated carbon filter 1630 is used to remove the odor. In this way, the drinking water purification treatment is completed.

This embodiment takes two thermoelectric wafers 1314 as an example, but may be single or more. In addition, the bottom plate 1312 of two viewing angles is simultaneously illustrated in FIG. 3 for convenience of explanation, but actually only a single bottom plate 1312. The bottom plate 1312 has a first surface 1312A and a second surface 1312B opposite to each other. The second surface 1312B has a first spoiler 1312C. The thermoelectric wafer 1314 is disposed on the first surface 1312A of the bottom plate 1312 to directly contact the cold water tank 1320. The cover plate 1316 is assembled to the second surface 1312B of the bottom plate 1312. The cover plate 1316 has a second spoiler 1316A facing the surface of the second surface 1312B.

The immersed electric heating tube 1440 extends into the high temperature hot water tank 1430 to serve as a heating heat source for the high temperature section drinking water. When the heating capacity of the second thermoelectric element 1410 used is insufficient, the submerged electric heating tube 1440 can be used to obtain hot water of high temperature. A temperature detector 1920 is disposed in the high temperature hot water tank 1430, and the opening and closing of the water immersion electric heating tube 1440 is controlled accordingly. A water level detector 1910 is also disposed in the high temperature hot water tank 1430 to control the control valve 19 that is connected to the low temperature hot water tank 1420. The heating system 1400 has, for example, a pressure equalization tube 1450. The pressure balance pipe 1450 communicates with the low temperature hot water tank 1420 and the high temperature hot water tank 1430 to balance the pressure in the high temperature hot water tank 1430 by the pressure relief valve 1422 of the low temperature hot water tank 1420. The high temperature hot water bladder 1430 communicates with the hot water control valve 1530 via line 1800 to provide hot water.
