Description

Horizontal electric water heater

The horizontal electric water heater of this case is related to the general horizontal electric water heater. In more detail, it is aimed at how to combine the advantages of the currently used water storage type and instant heat electric water heater with a single electric water heater, and reduce the installation height of the water storage tank. It also provides structural inventions that provide continuous source of hot water for the convenience of the user.

According to the current water heater, it is mainly divided into two types: water storage type and instant heat type.

The water storage type electric water heater is used for a family with a large population, and has a cylindrical vertical storage bucket with a heating rod inside, and the water stored in the water storage tank can be heated when it is not used normally. The rod heats the water stored in the water storage tank, and the heating water in the barrel is heated to a certain temperature (generally 65 ° C), then the heating is stopped, and when the water temperature drops to the set temperature (generally 55 ° C), the heating is restarted. The storage water in the water storage tank is maintained at a preheating temperature within a certain range to provide the user with the use at any time.

However, the above-mentioned water storage type electric water heaters are mainly used for storing water in a storage tank for a large amount of water, and the water storage tanks have to occupy a large space, so they can only be placed at the balcony. Although the balcony provides a large space for the storage bucket to be placed, in the case of Taiwan, the balcony space of each building is relatively small, resulting in the depth of the storage tank body. There is still room for improvement in the space where it is placed. In addition, it cannot be directly installed in the bathroom, so that the initial installation requires a long pipeline to be buried, which results in a complicated installation and the pipeline between the sections. The heat loss of the pipeline is formed; and, due to the certain amount of water stored, and the hot water pipe of the shower head or the faucet is opened by the user to make the hot water output from the hot water pipe of the water storage tank, how much heat is discharged from the hot water pipe of the water storage tank Water must be equivalent to the same amount of cold water from the cold water pipe into the interior of the water storage tank, and it must be heated by the heating rod to store the water in the whole bucket storage tank. It takes a lot of electricity and time to heat up, and it usually takes at least one hour to match the volume, which results in considerable power consumption.

Instant heat electric water heaters are generally used in places with a small number of people such as small suites, and because of their small size, they can be directly installed in the bathroom, when the shower head or the hot water end of the faucet is used, directly The water pressure of the water heater is used to activate the pressure switch of the water heater to start heating the heating rod to provide hot water use.

However, the above-mentioned instantaneous heat type electric water heater activates the heating rod to instantaneously heat the cold water flowing through the pressure switch of the water heater due to the water pressure when the water flow is mainly flowing, so that the cold water flowing through is heated by the instant heating. The temperature is used for the purpose, so the water temperature will be affected by the flow rate of the water flow, and the occurrence of cold and heat will occur; in particular, if the flow rate of the water is too small, the pressure switch cannot be activated at all, and the pair is located at the end of the pipeline. For users, it is simply not available.

Therefore, when it can be found that there is no improvement in the instantaneous electric water heater of the water storage type electric water heater.

Furthermore, the structural invention of the "Electric Water Heater Structure with Heat Storage and Instant Heat" (certificate No. I308206) for the improvement of the above-mentioned water storage and instant heat water heaters, and its structural features, The technical means and the intended purpose of the invention are as shown in the first aspect of the invention patent document, from the fifth line of the fifth page to the eleventh line of the eleventh line [embodiment]. A partition plate (20) is disposed in the heat storage cylinder (10), and a cold water inlet pipe (30) and a hot water outlet pipe (40) are disposed through the inner and outer portions of the heat storage cylinder (10), and are matched and stored. The hot water (10) is heated by water inside, and the electric heat storage cartridge (10) is provided with an electric heater (50), wherein a hanging group (11) is arranged above or on one side of the outer circumference of the heat storage cylinder (10). For fixing the heat storage cylinder (10), the partition plate (20) is in the shape of a crucible, which makes the heat storage cylinder (10) be divided into a heat storage space (12) and an instantaneous heat space (13), and a heat storage space ( 12) For the upper half to extend into the lower rear space, the instantaneous heat space (13) extends to the front upper space for the lower half and the hot and cold mixed exchange space below the heat storage space (12) (1) 21), above the instantaneous heat space (13) is a high temperature space (131), and the partition plate (20) is disposed between the heat storage space (12) and the instantaneous heat space (13) above the vertical partition (21) There is an upper through hole (22), and a lower through hole is provided at the lower vertical partition (23) (24) The cold water inlet pipe (30) is connected to the water flow at a normal temperature, which is connected to the hot and cold mixed exchange space (121) of the heat storage space (12), and the water inlet of the cold water inlet pipe (30) An inductor (60) is disposed at the heat storage cylinder (10), and the hot water outlet pipe (40) is connected to the outside by a high temperature space (131) of the instantaneous heat space (13) to heat to a set temperature. The water flow is guided for use, and the electric heater (50) is placed in front of the heat storage cylinder (10) and bent to extend into a length space below the instantaneous heat space (13), and cooperates with the lower through hole ( 24), and the electric heater (50) is connected to the inductor (60).

The use of the structure, as shown in Figures 3 and 4, when there is no water or water shortage in the heat storage cartridge (10), the water flow is introduced by the cold water inlet pipe (30) to make the heat storage cartridge (10) The heat storage space (12) and the instantaneous heat space (13) are both filled with spare water, and the water source is heated by the electric heater (50) so that the water source in the entire heat storage cylinder (10) reaches a certain setting. Temperature, during heating, the electric heater (50) is the water source in the instantaneous heat space (13) where it is heated. When the water temperature in the instantaneous heat space (13) gradually rises, it will pass through the convection. The upper and lower through holes (22) (24) cause hot and cold convection inside the heat storage cylinder (10) until the temperature in the entire heat storage cylinder (10) reaches the set temperature, and the inductor (60) senses and controls The electric heater (50) stops heating, and the internal hot water is kept warm by the heat storage cartridge (10).

The use of hot water, after the hot water is turned on, the hot water is derived from the hot water outlet pipe (40) at the high temperature space (131) of the instantaneous hot space (13), as shown in Fig. 4, to provide When hot water is used, when the hot water flows out from the hot water outlet pipe (40), the cold water is replenished by the cold water inlet pipe (30), and when the cold water is replenished by the cold water inlet pipe (30), it is mixed with hot and cold water. The exchange space (121) is mixed with hot water, so that the water temperature of the heat storage space (12) in the area is slightly decreased, and the small molecule of hot water pushes the hot water of the large molecule forward, so that the hot water is stored by the heat. The hot water in the space (12) flows from the upper through hole (22) to the high temperature space (131), and the hot water under the hot and cold mixed exchange space (121) enters through the lower through hole (24), and the instantaneous hot space (13) The hot water at the place is sent to the upper space by the high temperature space (131), so that the hot water passing through the upper through hole (22) from the heat storage space (12) and the hot water flowing from the instantaneous hot space (13) Mixing, generating the thermal effect of temperature rise, so that the water flowing out of the high temperature space (131) is sufficient temperature, and when the hot water is used in a large amount, the water temperature in the entire heat storage space (12) space is drop , And (13) in space using instantaneous space thermal electric heater (50) of the heating, so that temperature can be maintained in the region over the temperature, and There is a partition plate (20) between the heat storage space (12) and the instantaneous heat space (13), so the water temperature does not directly interfere. When the hot water is used continuously, the hot water is directly in the instantaneous heat space ( 13) After being heated, it is sent to a high temperature space (131) and is led out by a hot water outlet pipe (40). The water flow is continuously heated by the lower through hole (24) into the instantaneous heat space (13), in the heat storage space (12). The water temperature is too low, which is sensed by the inductor (60) and controls the heating of the electric heater (50). At this time, the water flowing into the instantaneous heat space (13) is directly electrically heated (50). The heating, after heating, will flow to the upper high temperature space (131), so the water source in the high temperature space (131) will always maintain the preset high temperature, and the partition plate (20) can separate two different temperature changes. Water source area.

The above structure, although it can be designed like a water storage type electric water heater, can be directly installed in the bathroom by a heat storage cylinder (10) having a small volume, so that a long tube can be connected. Road, and as long as there is hot water release, there is cold water injection heating, not as the existing instant hot water heater may change the temperature due to insufficient water pressure or different water output, resulting in the lack of water temperature And when it is used, the hot water is taken out from the hot water outlet pipe (40) at the high temperature space (131) of the instantaneous heat space (13) to produce hot water for use, when the hot water is discharged from the hot water How much water pipe (40) flows out, how much cold water inlet pipe (30) is replenished, and when cold water is replenished by cold water inlet pipe (30), it is mixed with hot water in its hot and cold mixed exchange space (121) to make the zone The water temperature in the heat storage space (12) drops, and when it drops to a certain temperature, it is induced by its inductor (60), and the electric heater (50) is controlled to heat up to provide an instant electric water heater like the one. The function.

In the above structure, when the user wants to start using the hot water to open the hot water end of the shower head or the faucet, the hot water can be exported from the hot water outlet pipe (40) at the high temperature space (131) of the instantaneous heat space (13) to reach the heat. How much water flows out of the hot water outlet pipe (40), and the cold water is supplemented by the cold water inlet pipe (30); however, it acts as a heat storage space (12) and a heat storage space (12) 13) The partition (20) is in the shape of a crucible and consists of an upper vertical partition (21), a horizontal partition and a vertical partition (23), that is, the upper vertical partition (21), The horizontal partition plate and the lower vertical partition plate (23) are perpendicularly connected to each other to form a partition (20) between the shapes of the top, so that The vertical partition (21) and the horizontal partition, the horizontal partition and the lower vertical partition (23) are perpendicularly connected to each other, and a water flow stagnation zone is formed respectively, so that the water flow cannot be completely smooth during the convection process, resulting in The cold water is replenished into the heat storage space (12) by the cold water inlet pipe (30) and mixed with the hot water in the hot and cold mixed exchange space (121), so that the water temperature of the heat storage space (12) in the area is slightly decreased, and The small molecule of hot water pushes the hot water of the macromolecule forward, so that the hot water in the heat storage space (12) flows to the high temperature space through the through hole (22) provided on the upper vertical partition (21) ( 131), and the hot water under the hot and cold mixed exchange space (121) is entered by the through hole (24) provided on the lower vertical partition (23), and the hot water at the instantaneous heat space (13) is turned upwards. The high temperature space (131) is sent, and the hot water from the heat storage space (12) through the upper through hole (22) is mixed with the hot water heated by the instantaneous heat space (13) to generate the heat effect of the temperature rise, and further In order to make the water flowing out of the high temperature space (131) sufficient temperature effect and purpose, it is invisibly discounted and needs to be improved.

Secondly, when the hot water is continuously used in a large amount, the water temperature of the entire heat storage space (12) is lowered, and thus must be heated by the electric heater (50) provided in the instantaneous heat space (13). When the water flow heated by the electric heater (50) is continuously derived from the hot water outlet pipe (40) at the high temperature space (131) of the instantaneous heat space (13), it may be through the partition plate (20). The interval, so that the electric heater (50) only heats the water flow in the instantaneous heat space (13), and provides the water temperature at the instantaneous heat space (13) in a short time, however, due to its How much is discharged from the hot water outlet pipe (40), and the cold water is replenished by the cold water inlet pipe (30). In addition, it is in the shape of a partition plate (20) in the heat storage space (12), and the instantaneous heat space (13) The upper vertical partition (21) is provided with an upper through hole (22), and the lower vertical partition (23) is provided with a lower through hole (24), especially on the upper vertical partition (21). The through hole (22) is such that the heat storage space (12) communicates with the high temperature space (131) in the instantaneous heat space (13), and the water flow of the hot water outlet pipe (40) is from the high temperature space (131). Exported inside, so that the cold water inlet pipe (30) is added to the heat storage The cold water in the space (12), wherein the cold water of the cold heat exchange space (121) in the lower part of the heat storage space (12) flows from the lower vertical partition (23) and the through hole (22) flows into the instantaneous space ( 13) The electric heater (50) is heated to increase the temperature, and the cold water in the upper portion of the heat storage space (12) will occur when the electric heater (50) is not heated at all. The upper through hole (22) of the upper vertical partition (21) directly flows into the high temperature space (131) in the instantaneous heat space (13), and the hot water outlet pipe (40) disposed in the high temperature space (131) with the water outlet. A serious loss is also derived.

In particular, the entire interior of the heat storage cylinder (10) is partitioned into a heat storage space (12) and an instantaneous heat space (13) by a partition plate (20), which is provided as an electric heater (50) for heating the water stream. In the instantaneous heat space (13), the inductor (60) that controls the electric heater (50) to start heating or cut off the power supply and stop heating is set in a lower temperature heat storage space (12). The area, but completely unable to measure the true water temperature in the hot space (13) as the heating space, causing the water temperature sensed by the sensor (60) when the user stops using the hot water and closes the shower head or the faucet. The temperature at which the electric heater (50) is stopped from heating (ie, 65 ° C) has not yet been reached, so that the electric heater (50) inside the instantaneous heat space (13) located at a higher temperature state will continue to be located in the instantaneous heat. The water in the space (13) is continuously heated and heated. Therefore, when the temperature of the heat storage space (12) measured by the inductor (60) reaches a preset power cutoff and the electric heater (50) stops operating ( That is, 65 ° C), the water temperature inside the instantaneous heat space (13) of the heat storage cylinder (10) is inevitably higher than the preset temperature of stopping heating, and even higher than Seriously, the entire heat storage cylinder (10) must withstand the high pressure generated by the high temperature, and there is a collapse of the heat storage cylinder (10) due to the high pressure, which is the biggest shortcoming and hidden worry. And urgently need to improve.

The present invention is directed to the improvement of the aforementioned structural defects and undesirable aspects. Therefore, the main object of the present invention is to provide a horizontal electric water heater comprising: a water storage tank, a partition, a heating rod, a hot water outlet pipe, a cold water inlet pipe and a temperature sensor. Wherein, the partition partitions the water storage tank into a heat storage space and an instantaneous heat space, and the water inlet and the heating rod of the hot water outlet pipe are disposed in the instantaneous heat space, and the water outlet of the cold water inlet pipe is disposed in the heat storage space. The temperature sensor is disposed on the outer wall of the water outlet of the cold water inlet pipe of the water storage tank; in particular, the partition is inclined from the inner bottom end of the water storage tank toward the top end, so as to be separated into the instantaneous heat space bottom space It can be larger than the upper space, and the heating rod is inserted into the bottom end of the instantaneous heat space. The upper part of the baffle is provided with a pair of flow tubes in the direction of the heat storage space, and the end of the convection tube is provided with a backstop for opening and closing control, and the partition plate Lower section The convection tube is arranged in the direction of the instantaneous heat space, and the end of the convection tube is also provided with a backstop for opening and closing control, and a temperature sensor is arranged on the outer wall of the water storage barrel outside the instantaneous heat space; accordingly, the electricity is made The water heater reduces the installation height and the water level in the storage tank is ensured. The storage level can be preheated and stored in the water storage tank. When the shower head or the hot water end of the faucet is opened, the hot water flows out and the cold water is injected into the heat storage space from the cold water inlet pipe. When inside, the heating rod is activated to make the hot water flow out continuously for convenient use.

The remaining structural features and operations of the case will be discussed in the form of a graphic description.

As shown in the first to seventh figures, the horizontal electric water heater of the present invention comprises: a water storage tank 2, a partition 3, a heating rod 4, a hot water outlet pipe 5, a cold water inlet pipe 6 and a temperature sensor 7; wherein the partition 3 partitions the water storage tank 2 into a heat storage space 21 and In the instantaneous heat space 22, the water inlet 51 and the heating rod 4 of the hot water outlet pipe 5 are disposed in the instantaneous heat space 22, and the water outlet 61 of the cold water inlet pipe 6 is disposed in the heat storage space 21, and the temperature sensor 7 The utility model is disposed on the outer peripheral wall of the water outlet port 61 of the cold water inlet pipe 6 of the water storage tank; in particular, the partition plate 3 is inclined from the inner bottom end of the water storage tank 2 toward the top end, so as to be separated into the bottom space of the instantaneous heat space 22 The heating rod 4 is inserted into the bottom end of the instantaneous heat space 22, and the upper part of the partition 3 is arranged in the direction of the heat storage space 21 with a convection tube 31, and the end of the convection tube 31 is provided for opening and closing. The reverse block 311, the lower part of the partition 3 is arranged in the direction of the instantaneous heat space 22 with a convection tube 32, and the end of the convection tube 32 is also provided with a backstop 321 for opening and closing, and the storage tank has two instantaneous heat spaces. A temperature sensor 8 is additionally disposed on the outer peripheral wall of the outer wall 22 .

With the above composition, since the water storage tank 2 is disposed in a horizontal manner as a whole, when assembled in the ceiling wall surface of the bathroom, the height of the water tank 2 protruding from the wall surface can be greatly reduced, and the height of the space occupied by the water tank 2 can be reduced. .

As shown in the second and third figures, when the initial installation is completed and the water storage tank 2 is in a waterless state, the cold water inlet pipe 6 can be used to introduce water into the heat storage space 21 through the water outlet 61, and the water flow can flow in. The convection tube 32 disposed in the lower portion of the baffle 3 in the direction of the instantaneous hot space 22 pushes the backstop 321 at the end of the convection tube 32 into the instantaneous heat space 22, so that the water flows through the upper portion of the partition 2 toward the heat storage space 21 The convection tube 31 is disposed in the direction, and the backstop 311 at the end of the convection tube 31 is pushed open, so that the water flow enters the heat storage space 21 again to form a circulating convection passage, and the heat storage space 21 and the instantaneous heat space 22 are filled. Spare water.

As shown in the fourth and fifth figures, further, the switch for controlling the heating rod 4 inserted into the bottom end of the instantaneous heat space 22 from the water storage tank 2 to start heating can be turned on (all are not drawn), so that the rapid parasitic instantaneous heat space is enabled. The water stored in the heating water in 22 is heated to increase the pressure of the water in the instantaneous heat space 22 due to the increase of the temperature. The upper part of the instantaneous heat space 22 passes through the upper part of the partition plate 3 of the water storage tank 2 toward the heat storage space 21 The inside of the convection pipe 31 is disposed, and the reverse stop piece 311 pivoted at the end of the convection pipe 31 is pushed into the heat storage space 21, and the convection mode is passed, so that the water flows through the lower part of the partition plate 3 provided in the water storage tank 2 The inside of the convection tube 32 is provided in the direction of the hot space 22, and the same The backstop 321 pivoted at the end of the convection tube 32 is pushed open into the instantaneous heat space 22, so that the in-situ instantaneous heat space 22 is heated at a higher temperature and the water storage line of the heat storage space 21 is convectively heated, so that the water storage tank When all the stored water in 2 reaches a predetermined temperature (generally 65 ° C), the temperature sensor 7 senses the set temperature and cuts off the power supply, so that the heating rod 4 stops heating; and if the user does not use the hot water immediately, When the water temperature in the barrel drops to a set low temperature (generally 55 ° C), the heating rod 4 can be restarted, so that the hot water in the water storage tank 2 is maintained between 55 ° C and 65 ° C.

As shown in the sixth and seventh figures, when the user starts to use the hot water, the hot water in the hot space 22 of the water storage tank starts to flow from the hot water outlet pipe 5 to the hot water end of the shower head or the faucet. The cold water is simultaneously injected into the heat storage space 21 of the water storage tank 2 from the water outlet 61 of the cold water inlet pipe 6, so that the water flow flows into the convection pipe 32 disposed in the lower portion of the partition 3 toward the instantaneous heat space 22, and the convection is pushed away. The backstop 321 at the end of the tube 32 enters the instantaneous heat space 22, and at the same time, the temperature sensor 7 on the barrel wall of the storage tank 2 is configured to control the activation of the heating rod 4, and only The water in the instant heat space 22 is simply heated, and the partition 3 is inclined from the inner bottom end of the water storage tank 2 toward the top end, so that the water heated by the heating rod 4 can smoothly flow to the instantaneous heat space. In the upper section of the upper portion of the partition plate 3 of the water storage tank 2, the backstop 311 of the end of the convection tube 31 disposed in the direction of the heat storage space 21 is closed (as shown in the sixth figure), plus, based on water The principle of flowing out in the direction of fast flow rate, the hot water can be continuously discharged from the hot water outlet pipe 5 The output is available for use.

Further, when the user stops using the hot water to close the shower head or the faucet, the water outlet 61 of the cold water inlet pipe 6 of the water storage tank 6 enters the temperature sensor 7 provided in the wall of the water tank 2, which senses the water storage. The water storage temperature inside the inner heat storage space 21 of the barrel 2 has not reached the temperature at which the heating rod 4 stops heating (ie, 65 ° C), so that the heating rod 4 in the instantaneous heat space 22 located in the higher temperature state continues to The water located in the instantaneous heat space 22 is continuously heated and heated, and is additionally monitored by the temperature sensor 8 provided on the instantaneous heat space 22, and the actual water temperature inside the instantaneous heat space 22 is known. The hot water which is subjected to high pressure due to continuous heating can be again disposed inside the convection pipe 31 in the direction of the heat storage space 21 via the upper portion of the partition plate 3 provided in the water storage tank 2, and is pivoted at the end of the convection pipe 31. The backstop 311 is pushed open In the heat storage space 21, and through the convection mode, the water flows through the inside of the convection pipe 32 disposed in the direction of the instantaneous heat space 22 in the lower portion of the partition plate 3 provided in the water storage tank 2, and is also disposed at the end of the convection pipe 32.
