Instant heating type water heater under cabinet

Abstract

The invention discloses an instant heating type water heater under a cabinet. The instant heating type water heater comprises a water heater casing, a cold water inlet port and a hot water outlet port, wherein an electric heating pipe is arranged inside the water heater casing; a water inlet is arranged at the lower end of the water heater casing; a water outlet is arranged at the upper end of the water heater casing; the cold water inlet port is connected with the water inlet; the hot water outlet port is connected with the water outlet; a water flow switch is arranged between the hot water outlet port and the water outlet; and a throttling bayonet is formed in the cold water inlet port or the hot water outlet port. The instant heating type water heater has the advantages that the discharged water temperature in the low water temperature situation in winter can be increased under a limited heating power condition, and the throttling bayonet is formed in the water outlet of the water heater to control the hydraulic pressure of the discharged water flow to be below the normal hydraulic pressure, namely lower than 3 L / min through a smaller pipe diameter, so that the required discharged water temperature can be reached under a lower heating power condition, and can save water at the same time.

Description

technical field [0001] The invention relates to a water heater, in particular to an under-cabinet instantaneous water heater. Background technique [0002] The instant water heater is a convenient and energy-saving water heater, because it does not need to heat the water in advance and store it in the insulated water tank, and it can be used as soon as it is turned on, which avoids the heat loss after the water is heated in advance. But the instant water heater also has a fatal problem, that is, the power consumption of the water heater is quite large when it is in use, usually at least more than ten kilowatts, and the power supply lines of ordinary households often cannot bear such a large power consumption, so the use is restricted. limit. [0003] There is also an instant electric water heater, whose power is much smaller than that of ordinary instant water heaters, below 3kw, but on the one hand, the heating effect is not good when used with such a small power, especial...

Problems solved by technology

But the instant water heater also has a fatal problem, that is, the power consumption of the water heater is quite large when it is in use, usually at least more than ten kilowatts, and the power supply lines of ordinary households often cannot bear such a large power consumption, so the use is restricted. restricted

[0003] There is also an instant electric water heater, whose power is much smaller than that of ordinary instant water heaters, below 3kw, but on the one hand, the heating effect is not good when used with such a small power, especially when it is most needed in winter , often not reaching the desired water temperature

In addition, because I brought the faucet myself, the style and grade of the faucet are relatively general, which limits the users who want to use a relatively high-end special faucet. Therefore, it restricts its market in a considerable way, especially in the new house decoration market, so this product is only available in the market. There is a certain market for low-end products
